Description
This invention relates to barges and more particularly to the
provision of a plurality of portable, sectional, self-contained,
floatable units which are capable of being transported over land by
a suitable vehicle with the sections being later assembled in the
water or along the banks of a stream, if desired, and later dragged
or slid into the water.
Portable barges of this type, which are transportable either by
truck over a highway or by railroad car to landlocked or otherwise
inaccessible bodies of water (lakes, canals, river cut-offs, etc.),
have considerable utility. Thus, the utility of portable
assemblable barges has been well-known heretofore and although
patents have been obtained thereon, it has been found during usage
of these known barges that their design features leave much to be
desired, particularly since their manner of construction has been
expensive and the means by which the plurality of sections are
locked in assemblable relation have not proved to be entirely
satisfactory; thus, their public acceptance has been anything but
phenomenal.
Such barges are easily transportable overland, in the form of a
plurality of stacked units, to a particular site by a large motor
vehicle or flat bed truck as well as by railroad flat cars and they
afford an expedient answer to the desirability of moving heavy
equipment across bodies of water, and may be also secured when in
assembled relation in a mud flat or marsh land by suitable
retractable pile members when this is desired.
Thus, it is the principal object of the invention to provide a
plurality of self-contained, floatable barge sections which are
capable of being more readily assemblable than any known heretofore
by reason of the construction and design of the units, the end and
side walls of each of which are formed complementally to one
another.
Another object of the invention is to provide a plurality of
sections of a barge which have a latching means insertable from the
deck of the barge.
Still another object of the invention is to provide portable barge
units and ramps therefor, all of which are assembled in adjacent
relationship and latched together into a complete organization of
predetermined size by locking members.
Yet another object of the invention is to provide a novel
interlocking system for innumerable other types of float sections
such as dredges, pontoons as well as towboats.
Another object of the floatable elements described herein combines
the weight advantage achieved by the utilization of complementally
formed corrugated side and end platings with the precise
interfitting of the walls of adjacent units upon assembly.
Another object of the invention is to provide buoyant units of
almost any size and shape consistent with the specific purposes for
which they are desired.
The invention will be better understood, and further objects and
advantages will become more apparent, from a reading of the
following detailed specification taken in conjunction with the
drawings, in which:
FIG. 1 is a top plan view of a barge of predetermined size
constructed of a plurality of floatable units, to one edge portion
of which is secured a series of ramps;
FIG. 2 is a side elevational view of a barge assembly shown in FIG.
1;
FIG. 3. is a partial side elevational and partial cross-sectional
view of a spud socket used for positioning the portable units
individually or as a group in a body of water or marsh land;
FIG. 4 is a fragmentary view in vertical cross section through two
adjacent units illustrating the complementally abuttable adjacently
arranged wall sections with a pin in position to be inserted as
soon as the units are attached;
FIG. 5 is a section on line 5--5 of FIG. 1 showing the units of
FIG. 4 in assembled condition with the latching means in position;
and
FIG. 6 is an alternative embodiment of a male and female assembly
for abuttable sections with the pin inserted to lock them in
position.
Turning now to FIG. 1, there is shown a barge indicated generally
at A which has been assembled from a plurality of floatable units
10 and each of which is provided with a forwarding projecting ramp
section 11. These units can be of any width and length desired and
the construction shown in FIG. 1 will be best understood by stating
that its overall length including the ramps is approximately 90
feet; however, the standard length of a unit for a portable barge
has generally been chosen to be 40 feet, although they may be built
in increments extending anywhere from 10 feet up to 60 feet.
The floatable units 10 are each provided with at least a pair of
equally spaced means defining vertical openings or recesses 13 that
are provided with fixed bar members 15 by means of which the units
may be lifted from a suitable land vehicle or railroad flat car by
manual or power-driven means and lowered into the water and vice
versa.
The portable units from which the barge is constructed are built up
from vertically disposed and longitudinally extending framing
members 16 and 17, respectively, (see FIG. 4), which are welded to
diagonal braces 18 with the complementally formed side walls 20 and
end walls 21 and 21' being welded to the framing members 16 and 17
and plate steel top and bottom elements 22 and 23,
respectively.
Also shown in FIGS. 1, 2 and in greater detail in FIG. 3, are means
S--S which represent floatable spud sockets that are availed of for
securing the assembled units in a body of water such as mud or
marsh land. With further reference to FIG. 3 the floatable spud
socket unit 15' is provided with corrugated front and rear walls
16' and 17', respectively, which may be positioned against a mating
surface on any side or end wall of the floatable units 10. As shown
best in the plan view of FIG. 1, the spud socket includes a
perpendicularly disposed aperture 18' through which a spud device
19' may be inserted for firmly positioning the portable barge
relative to the bed of a stream or river.
As shown in the side elevational view of FIG. 2 and still better in
the fragmentary views of FIGS. 4 and 5, each of the floatable units
10 is provided with corrugated side walls 20 and end walls 21 and
21', the corrugations of each of the ends of which are provided
with vertically aligned perforations. See, for example, those shown
in wall 21 as at 25. The top deck portion 22 is also provided with
an aperture 27 that is aligned with the series of apertures 25
previously described.
It will be observed that each of the corrugations in the end wall
21 which is apertured, as described, is also provided on the
interior thereof with socket members 30a, 30b, 30c and 30d secured
thereto. These socket members are provided for a dual purpose,
first as a reinforcement and strengthening means for the
corrugations to prevent distortion thereof if a unit happens to be
mishandled in transit and while being assembled and disassembled,
and secondly, as a guide for the locking shaft member 32.
The corrugated wall 21' at the opposite end of this barge unit is
also provided with a series of vertically disposed, aligned
openings 35 with each corrugation through which the openings extend
being provided with aligned socket members 33a, 33b and 33c which
serve not only to reinforce each of the outwardly projecting
corrugations, but also to guide the locking shaft 32 into its
seated position when any two of the floating units are brought into
abutting relation.
As is well shown in both FIGS. 4 and 5, each of the corrugated end
walls 21 and 21' are bent backwardly toward the top deck and bottom
wall of the unit at 38, 39 and 40, 41, respectively, to provide
horizontally extending flanges to which the plate steel skin top
and bottom elements 22 and 23, respectively, can be attached.
In an alternative form of the invention, as shown in FIG. 6, each
of the end and side walls of the floatable units is provided with
complemental interengaging male and female portions 50 and 51,
respectively.
Further, the end wall 60 is deformed in such a manner as to provide
opposed horizontal walls 61 and 62 which are integral with the
vertically extending wall 51 and thus provide the outwardly
projecting male member or elongated nose section. This wall 51 is
reinforced by welding thereto a laterally extending rib 64 which
is, in turn, welded to a brace 65 that is secured to top and bottom
horizontally disposed framing members 66--66.
The companion barge unit adapted for attachment to the previously
described unit is in substantially all respects similar in
construction except for the fact that it includes outwardly
extending, spacedly arranged ledges 70 and 70' which extend
transversely the full length of the elongated nose or male portion
51.
As in the first embodiment of this invention, the deck is provided
with a transverse series of perforations (one shown as 75 in the
cross-sectional view of FIG. 6), each of which is in vertical
alignment with other perforations provided in the bottom of ledge
70 and the top of ledge 70'.
The male member 51 is correspondingly perforated transversely
thereof so that the locking pins 80 (one shown) may be inserted in
each opening.
As is also clearly shown in the second embodiment of the invention,
vertically arranged sleeve members secured to adjacent structure
for guiding pins 80 into proper position through the abutting hull
sections are provided.
It is to be understood that the walls of the spud socket which are
shown as being complemental to the barge structure of FIGS. 1 and 2
may be modified to mate with the alternative form of the invention
shown in FIG. 6.
Furthermore, it is contemplated that in lieu of the structure shown
in FIG. 3 being provided with an aperture to receive the spud its
body portion can be made of any configuration and be provided with
a power plant which may be attached to any side or end wall of the
barge to power the barge or any floatable unit thereof in a stream
or other body of water.
From the disclosure of this application it will be apparent that
since the side and end walls of the floatable units are designed in
the manner described that any particular assemblage of units can be
achieved. For example, longitudinal sections can be arranged to
abut the side walls of an adjacent section to an L-shaped assembly,
or three sections can be arranged to form a "U." Thus, any
conceivable arrangement of elements can be provided to meet the
desires of the customer.
