Description
BACKGROUND OF THE INVENTION
This invention pertains to ornamental, tapered columns, and more
particularly to columns formed of extruded sections.
1. Field of the Invention
This invention is particularly directed to ornamental tapered
columns which are entirely prefabricated from extruded plastic or
metallic sections.
2. Description of the Prior Art
Large columns have been used for support and ornamentation in
buildings for many centuries, particularly from the times of
ancient Greece and Rome to the present time. Massive masonry
columns are now used in many of our Federal, State and Memorial
Buildings.
These great columns always stood as a silent symbol of the
architectural splendor and grandeur of the past, and when specified
for public buildings of the present are usually designed to be
architecturally compatible with the design periods such buildings
represent; but the cost of producing and handling these great
columns today has almost eliminated their use.
Heretofore such columns were usually constructed of reinforced
concrete in several vertical sections to attain the desired height,
and were assembled at the building site to form the columns.
The base and cap or capital portions of these columns were usually
cast of concrete in the particular ornamental design required to
blend with the architectural period of the building, such as
"Doric," "Ionic," or "Corinthian," and were usually assembled with
the columns at the building site. This old style building procedure
necessitated the use of many expensive forms, heavy duty hauling
and handling apparatus, and a great deal of time for building and
installing each column, making the overall cost of producing such
masonry columns prohibitive today.
In accordance with the present invention, new and improved columns
and methods of prefabricating them have been provided which columns
may be tapered from bottom to top, having a fluted outer perimeter,
ornamental bases and caps or capital portions to produce simulated
versions of the great columns of old. The method disclosed
prefabricates such columns inexpensively, of lightweight, extruded
plastic or metallic sections which are simple to handle and easily
assembled into columns for building structural use.
SUMMARY OF THE INVENTION
It is therefore one object of this invention to provide a
prefabricated, tapered column formed of interlocking sections.
Another object of this invention is to provide a new and improved
method of preforming interlocking arcuate sections which, when
assembled, form a replica of the Doric, Ionic and Corinthian
architectural periods.
A further object of this invention is to provide an improved
extruded arcuate section which, when extruded in an elongated
section and assembled with other like sections, forms a structural
column.
A still further object of this invention is to provide an
extrudable section of plastic or metal which, when interlocked with
other like sections, forms a column.
A still further object of this invention is to provide an extruded
tapered column formed of a plurality of extruded arcuate sections
which interlock to form a column.
Further objects and advantages of the invention will become
apparent as the following description proceeds and the features of
novelty which characterize this invention will be pointed out with
particularity in the claims annexed to and forming a part of this
specification.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the various views of the drawings for a more
detailed description of the construction and other features of the
invention by characters of reference, FIG. 1 illustrates the
prefabricated, tapered column 10, assembled with its base member 11
and cap or capital member 12, as it would appear when installed in
a building structure.
The tapered column 10 is preferably prefabricated from a number of
hollow pre-assembled sectors 13, such as shown in FIGS. 6 and 7 and
in diagramatic form in FIGS. 2, 3, 4 and 5. These sections may be
formed of suitable plastic or metallic materials and as shown and
described here is formed of extrudable aluminum. As by way of
example, the preferred number of sectors 13 utilized to form the
tapered column 10 of this invention is twenty, and each sector is
pre-assembled to provide an 18 degree segment, radiating from the
center of a circular plane, having a predetermined outside and
inside diameter. Each of the sectors 13 is assembled into a single
unit by joining together, as at 14 in FIG. 6, the inner and outer
individually shaped extruded aluminum sections 15 and 16,
respectively.
The forming of the sections 15 and 16, which may be U-shaped in
cross-sectional configuration, only requires the use of two
extrusion dies, one to produce the shape of the inner section 15,
and the other to produce the shape of the outer section 16. These
sections and the resulting assembled sectors 13 fabricated
therefrom may be any desired length (from 20 to 30 feet or longer),
depending on the required height of the column being fabricated.
The desired outside and inside diameters of the column being
fabricated can readily be attained by increasing or decreasing the
arcuate widths and radial lengths of each inner and outer section,
and hence the assembled sectors or segments 13, so long as the
converging angular sides (represented by planes shown by dot-dash
lines 17 and 18 in FIGS. 6 and 7) of each sector 13 remain in
contacting alignment with the radial dividing lines of each 18
degree segment of the particular column.
It should be noted and understood that the number of sectors 13
utilized to form or fabricate the tapered column 10 of the
invention would not necessarily be limited to 20, or 18 degree
segments of a circle, as recited in the foregoing example of the
preferred embodiment; but that a column of any desired diameter
could be fabricated from any number of pre-assembled sectors
designed to have the same angular convergence as an equal number of
radial segments into which a perfect circle could be divided. In
the preferred embodiment shown, an equal number of sectors or
segments is utilized to allow for assembly and installation of the
column in two separate halves, the purpose of which will
hereinafter appear.
The inner and outer sections 15 and 16 are quickly and
inexpensively produced in any desired length by any known extrusion
method, and as previously stated, only one extrusion die is
required to obtain the desired shape of each section.
Each of the sections 15 and 16 are preferably shaped as shown in
FIG. 6, with their aligned converging sides represented by planes
17 and 18, angled to align with the radial dividing lines of a
predetermined segment of a circle, so that each assembled sector 13
will nestle within each adjoining sector (as shown in FIG. 7) to
form the diameter of the desired cylindrical column.
The inner and outer sections 15 and 16 are extruded of aluminum to
provide fairly thin and slightly flexible wall sections in the
desired shape. The inner section 15 is shaped with an arcuate faced
wall section 19 which extends to its angular converging left side
represented by plane 17, where it is provided with an angular
shaped detent or catch 20, and which extends on the right side to a
point 21 which is in radial alignment with the outer face 22 of the
inwardly depressed portion 23 of the angular converging right side
formed by plane 18. At this point wall section 19 is provided with
an angular depression or notch 24 which is adapted to receive in
locking relation another detent 20 on an adjoining section 15, as
clearly shown in FIG. 7.
The angular converging or diverging side walls represented by
planes 17 and 18 and the integrally depressed wall portions 23 of
sections 15 and 16 are designed to project inwardly or outwardly
approximately one half of the radial depth of an assembled sector
13, as indicated by the dot-dash line 25. The end 17" of the inner
section's portion of its diverging side wall and its diverging
depressed portion 23 are provided with inwardly projecting
extensions 26 having rounded cam-shaped ends 27 and outwardly
facing angular depressions or notches 28 in their opposed sides
which are adapted to mate with and receive the inwardly projecting
detents or catches 29. These catches are integrally formed on the
ends 17" of the outer section's portion of its converging side wall
represented by plane 17 and its portion 23' of the inwardly
depressed wall 23, to securely lock the inner section 15 and outer
section 16 into a single unit sector or segment 13.
The outer section 16 is shaped to provide an arcuate faced wall
section 30, which extends to the left converging side plane 17 of
the section, and is evident on the right side for a short distance,
ending in alignment with the radial outer face 22 of the depressed
wall portion 23 where it is provided with an angular depression or
notch 31. The arcuate faced wall section 30 is also provided at its
left end with an integral inwardly projecting detent or catch 32.
The notch 31 and the detent 32 are adapted to mate with identical
detents and notches in the adjoining outer sections 16 (as shown in
FIG. 7) to form the outer circular perimeter of the column being
assembled.
The arcuate faced wall section 30 is provided with an integral
concave wall section 33, which is substantially semi-circular in
shape and is located approximately midway between the angular
converging sides forming planes 17 and 18 of the outer section 16.
This concave wall section 33 is intended to simulate in appearance
the longitudinal flutes or concave depressions in the massive
masonry columns of the past.
Previous to the assembly of the inner and outer sections 15 and 16
into unit sectors 13 from which the tapered aluminum column 10 is
fabricated, another operation is required which will result in
tapering of the assembled column. Reference should be had to FIGS.
8, 9, 10 and 11 of the drawings which illustrate one method and the
equipment required to perform the tapering operation.
The tapering of the inner and outer sections 15 and 16 may be
accomplished by a simple rolling and pressing operation which is
performed on each piece or section before said sections are
assembled together to form sectors 13. In other words, this
operation results in the reduction of the overall cord widths of
each piece or section, as indicated by the dimensions "A" in FIG. 8
and "B" in FIG. 9 of the outer section 16, and also by the
dimensions "C" in FIG. 10 and "D" in FIG. 11 of the inner section
15, resulting in the reduction of the inner and outer cord widths
of the assembled sectors 13.
The rolling and pressing equipment required to accomplish a gradual
tapering of each section from one end to the other preferably
comprises two sets of three rollers each, one set 34 for the
operation on the inner sections 15, and one set 35 for the
operation on the outer sections 16. Each of the rollers 34 and 35
is journaled to rotate in opposed lever arms 36 or 37 of the
stationary tapering machine (not shown), which also includes
advancing mechanism for moving the extruded aluminum sections
through the machine.
The rollers 34 and 35 are preferably positioned with one roller
contacting the outside surface, and two rollers contacting the
inside surface of portion A' of section 16 in FIG. 8 and portion C'
of section 15 in FIG. 10 to be narrowed by the tapering operation.
It should be understood that each of the sections 15 and 16 upon
which the tapering operation is to be performed may be 20 or 30
feet in length, or even longer, to provide for the required height
of the column to be assembled from these individual sections.
The tapering operation described above must be done gradually and
accurately and the machine or mechanism employed must be nearly
automatic to advance the shaped sections through the rollers at a
constant speed and constant depression rate from one end to the
other end of the section being tapered. If only one pass through
the machine is not enough or if the depth of the depression being
formed is not enough to provide the necessary narrowing of that
particular section as shown in FIGS. 9 and 11 of the drawings and
indicated by the dimensions B' and D' respectively, then one or
more additional passes of the section through the machine must be
undertaken to provide further deepening of the formed depressions
and hence the required narrowing of sections 15 and 16. FIGS. 9 and
11 illustrate the final shape of the sections at the end of the
tapering operation.
Having described in the preceding paragraphs the features
pertaining to fabrication and tapering of the extruded aluminum
sections which are utilized to prefabricate the tapered aluminum
column 10 of this invention, the following steps are required to
assemble these components and base member 11 and capital member 12
into a complete column as shown in FIG. 1.
The inner sections 15 and the outer sections 16 are first joined
together as at 14 to form the individual sectors or segments 13.
This is easily accomplished by slightly bending the angular side
17" and the depressed wall portion 23 of sections 15 inwardly
toward each other and forcing the opposed sections 15 and 16 toward
each other, allowing the rounded ends 27 of the extensions 26 to
pass inwardly over the ends of the detents or catches 29 on the
ends of outer sections 16. This action causes the projecting
detents 29 to snap into the angular shaped notches 28 in the
extensions 26 of the inner section 15 to complete the assembly of
sections 15 and 16, resulting in the creation of a segment 13.
The pre-assembled sectors 13 are next assembled in locked
contacting radial relation to each other to form the cylindrical
tapered column 10. This is accomplished by aligning the angular
converging side formed by planes 17 and 18 of each sector 13 with
the like sides of the next sector to which it must be secured, and
sliding the right hand depressed portion, which is made up of the
wall portions 23 and 23' of each inner and outer section, over the
left hand extending portion which is made up of the wall portions
17' and 17" of each inner and outer section until the outer face 22
of the depressed portion meets the adjacent outer face of the left
hand extending portion, as clearly illustrated in FIG. 7.
When this nesting operation is being performed it automatically
causes the angular surfaces of the inner section detent 20, and the
outer section detent 32, to spread the arcuate faced outer wall
section 30 and the arcuate faced inner wall section 19 slightly
apart, and allows the detents 20 and 32 to snap into their
respective mating notches 24 and 31 in the inner and outer
sections. This nesting operation forms a portion of the inner and
outer cylindrical surfaces of the bore 38 and the outer perimeter
39 of the tapered column being assembled. The assembly of all the
sectors 13 in the same subsequent manner completes the assembly of
the column. In assembling this column these members must always be
first pressed into two halves, then these two halves are pressed
together; otherwise the last member will not go in place. This
mating operation can easily be done with two rocking jigs.
In order to add strength and stability to the assembled column and
to prevent longitudinal creeping of the assembled sections and
sectors of the column, especially during transportation to and
installation of the column at the building site, the tapered bore
38 of the column is provided at each open end with reinforcing
flanged sleeve members 40 and 41 as shown in FIGS. 2-5. These
sleeve members are adapted to fit snugly into the tapered bore 38
of the column and are provided at their outer ends with integral
flat cylindrical flanges 42 and 43, the diameters of which are
large enough to extend radially over the end surfaces 44 and 45 of
each of the assembled sections 15 and 16.
Each of the flanged sleeve members 40 and 41 is provided with
diametrically opposed pairs of integral inwardly projecting
brackets 46 and 47 at their inner ends, and each bracket is
provided with a hole or aperture through which a pair of cables or
rods 48 extend longitudinally from one end of the assembled column
to the other. These cables or rods 48 are preferably made of
aluminum material so as to have similar expansion and contraction
characteristics as the material of which the components of the
column are made. Each cable is secured in longitudinal compressed
relation to the outer surfaces of the brackets 46 and 47, as by
means of the collars 49, which are provided with set screws to
adjustably secure the cables or rods in taut relation between the
brackets, to thereby strengthen, reinforce and prevent longitudinal
movement of the many sections or components of the entire assembled
column as clearly shown in FIG. 5.
It should be noted that suitable means other than the cables 48,
adjustable collars 49 and their set screws, as shown, could be
utilized to accomplish the same purpose. For example, rods having
integral head portions at one end and threaded portions at their
other ends extending through the holes in brackets 46 where they
could be secured by nuts to provide the desired compression of the
column's components may be used.
Large prefabricated aluminum columns such as shown and described
could be used as weight-bearing support members if so desired; but
this would necessitate the use of thicker and stronger aluminum
sections for their fabrication. This would entail considerable
additional expense for material and fabricating operations.
Therefore in the preferred embodiment of the invention shown, these
large columns are not intended to be used as weight supporting
structural members and hence can be fabricated from thinner,
lighter and less expensive material, resulting in lower assembled
weight of the column and less expensive handling, transportation
and installation costs of the finished product.
In other words, the prefabricated, tapered aluminum column of this
invention has been designed to be ornamental in nature rather than
structural, and to simulate the appearance of the great heavy
masonry columns of old, without their inherent prohibitive
cost.
The columns of this invention are therefore designed to have the
large cylindrical bore 38 in their exact centers so they can be
installed in the building structure over and around suitable weight
bearing structural members such as "I" beams 50 (shown in dotted
line) in FIGS. 1, 2, 3 and 5. These "I" beams may be installed in
or on a concrete base 51, previously prepared at the building site
at the desired locations of the columns, in perpendicular relation
to the base 51 and are rigidly secured to the base. They are
somewhat longer than the assembled columns, so that they can be
securely attached at their tops to a horizontal structural member
52 before or after the surrounding column is installed. If the
assembled column is to be installed before the "I" beam 50 is
connected to the horizontal structural member, the column would be
delivered to the site completely assembled, and lifted by crane or
other suitable equipment with its base end above the top end of the
"I" beam, then carefully lowered directly over the upright beam
until its bottom end rests on the concrete foundation or base
51.
Should it be desired to install the column after the "I" beam has
been connected to the horizontal structural member 52, the column
would be pre-assembled and delivered to the site in two
semi-circular halves, where each half would be set up in vertical
position, adjacent to the "I" beam 50 and assembled or snapped
together to form the complete column surrounding the pre-installed
"I" beam.
Having thus installed the prefabricated, tapered aluminum column 10
in the building structure as above described, it remains only
necessary to install the ornamental base member 11 and the
ornamental cap or capital member 12 each in their respective
positions surrounding the lower end and upper end of the previously
installed column to complete the installation or erection of the
non-weight-bearing, tapered aluminum column of this invention.
The component parts of the base and cap members 11 and 12 are
preferably fabricated of aluminum by a rolling and pressing
procedure, especially for the simple Doric styled members shown in
FIGS. 1, 2, 3 and 5 of the drawings. The base member 11 comprises
two cylindrical upstanding sections 53 and 54, the section 54 being
of smaller diameter than the section 53 upon which it rests.
Section 53 is adapted to be held in concentric relation to the
center of column 10 which it surrounds by the inwardly extending
cylindrical flange or collar 55. The upper section 54 is provided
with a slightly tapered cylindrical flange or collar 56 which is
adapted to bear against the circumferential tapered wall portions
30 of the column for the same purpose. The circumferential portions
of the flange or collar 56 fit into the concave wall sections or
flutes 33 of the assembled column and can be made to fit snugly
thereinto by performing the additional operation of forming the
collar into a series of compound curves as shown in dotted line at
57 in FIG. 5. This can also be accomplished by initially making the
flange 56 in a contour pre-formed to match the outside contour of
the column at the point of contact with the same.
The top cap or capital member 12 is preferably fabricated in a
manner similar to that described for base member 11, that is, it is
made in two sections, an upper section 59 and a lower section 60.
The lower section is smaller in diameter than the upper section and
adapted to be held in concentric relation with the center of the
column by means of its semi-circular shaped exterior rim 61, shown
in FIG. 5, which interlocks with upper section 59. The lower
section 60 is also provided with a downwardly extending cylindrical
flange or collar 62 which may be made to match and mate with the
outside tapered, fluted contour of the column at its point of
contact in a manner similar to that described in connection with
the formation of cylindrical flange 56 on the upper base section
54.
The upper section 59 of the cap member 12 is provided with a pair
of opposed, flat cover members 63 and 64 respectively, the inner
parallel edges of which are spaced apart sufficiently to allow
clearance for the upwardly extending top end of the "I" beam
structural member 50. These cover members are of sufficient
thickness to slide between the underside of the horizontal
structural member 52 and the top face of the flat cylindrical
flange 43 of the sleeve member 41 to close up the gap therebetween.
These cover members also securely support the assembled capital
member 12 by means of the depending integral arcuate rims 65 and 66
which project downwardly in contact with the inside cylindrical
wall of the upper section 59, where they are secured as by means of
welding or otherwise, as clearly shown in FIG. 5.
The assembled base member 11 and the assembled cap member 12 could
each be constructed as individual units, to be installed on the
assembled columns in their respective positions at the factory,
allowing for transportation to and erection of the complete column
at the job site; but this method would increase the cost of
handling and erection of the completely assembled column. Therefore
the base member 11 and the capital member 12 of this invention have
been designed to be fabricated as two separate semi-circular
portions. Portions 67 and 68 form base member 11, and portions 67'
and 68' form capital member 12. These half portions of the base and
capital members are installed in their respective positions
surrounding the erected column by sliding the two half portions
together until their mating edges meet at the central dividing line
69, where they are securely held together to form the base or
capital by means of suitable snap-locking spring catches or latches
70. One element of each of the latches is mounted on the opposite
halves of the inside cylindrical walls of the upper and lower
sections that form the assembled base member or cap member 12, as
clearly shown in FIG. 4.
It should be noted that neither the base member 11, the capital
member 12, or the assembled column itself carries any load, but are
designed to completely surround and cover the load bearing "I" beam
structural support member 50 to thereby enhance the appearance and
lessen the cost of the completely installed ornamental column. It
is also conceivable that other designs of the base and cap members
could be substituted for the Doric styled members shown and
described because of their simplicity and consequently minimum cost
factor involved in the use of such styling; but that other styles
of ornamental bases and capitals such as the elaborate Ionic or
Corinthian period designs could be used if they fitted the desired
architectural design motif of the structure.
Such departure from the Doric styled base and capital members shown
to the Ionic, Corinthian or other styles would merely require such
members to be fabricated of cast aluminum, with open contoured
tapered bores which would receive and closely surround the lower
and upper contoured circumference of the erected column.
Although but one embodiment of the invention has been shown and
described, it will be apparent to those skilled in the art that
various changes and modifications may be made therein without
departing from the spirit of the invention or from the scope of the
appended claims.
