Description
BACKGROUND OF THE INVENTION
This invention relates to paint brush and paint roller cleaning
devices, and particularly to such a device for holding either a
paint brush or a paint roller, and adapted to be rotated about its
longitudinal axis to effect cleaning of a paint brush or paint
roller through the action of centrifugal force. Other devices to
effect cleaning of paint brushes and paint rollers by centrifugal
force are known, but such devices are usually complex mechanical
structures expensive to purchase and complicated to use.
Accordingly, it is one of the objects of the present invention to
provide a holding device for a paint brush or a paint roller which
is both economical to manufacture and simple to use.
Another object of the invention is to provide a paint brush and
roller cleaning device constituting an elongated tubular structure
embodying holding means along its inner and outer periphery, the
holding means associated with the inner periphery being effective
to retain the handle of a paint brush, while the holding means
associated with the outer periphery are effective to retain a paint
roller in place while it is being rotated.
The invention possesses other objects and features of advantage,
some of which, with the foregoing, will be apparent from the
following description and the drawings. It is to be understood
however, that the invention is not limited to the embodiment
illustrated and described, since it may be embodied in various
forms within the scope of the appended claims.
SUMMARY OF THE INVENTION
In terms of broad inclusion, the invention comprises an elongated
tubular body sections of the wall of which have been displaced in
reference to the inner and outer periphery of the tube so as to
define a restricted passageway within the confines of the tube
within which the handle of a paint brush may be inserted and
resiliently held, while also providing resilient wall portions
projecting beyond the outer periphery of the tube and over which
may be inserted a paint roller, to be held by the resilient
projecting wall portions impinging upon the inner periphery of the
paint roller. One end of the elongated tubular body is provided
with a stub shaft adapted to be mounted in the chuck of a drill
motor so as to effect rapid rotation of the device with brush or
paint roller mounted thereon, so as to effect cleaning thereof
through the action of centrifugal force.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a plan view illustrating the device as used in
conjunction with a paint roller, the latter being shown in broken
lines.
FIG. 2 is a vertical cross-sectional view taken in the plane
indicated by the line 2--2 in FIG. 1, and illustrating sections of
the wall of the tubular body projecting inwardly and outwardly in
relation to the inner and outer peripheries of the tubular
body.
FIG. 3 is an elavational view illustrating the use of the device in
connection with the cleaning of a paint brush.
FIG. 4 is a view similar to FIG. 3, but showing the device in use
for the purpose of cleaning a paint roller.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In terms of greater detail, the paint brush and roller cleaning
device of the invention comprises a generally elongated tubular
member designated generally by the numeral 2, and including a
generally cylindrical wall 3, preferably fabricated as a tubular
member from an appropriate synthetic resinuous material such as
polyvinyl chloride, and having an overall length of about 7 inches
and a diameter of about 1 1/4inch. As illustrated in FIGS. 1 and 2,
the tubular member 2 is provided with inwardly projecting resilient
sections 4 spaced equally about the periphery of the tube and which
project inwardly to produce a constricted throat or passageway 6
into which the handle of a paint brush 7 may be inserted and
resiliently retained between the resilient portions 4. Each of the
resilient portions 4 forms a part of the original wall of the tube
2, and is formed by cutting pairs of parallel elongated slits 8 in
the wall and under heat and pressure depressing the portion of the
wall 4 thus separated from the main body of the tube until it
achieves the position illustrated in FIG. 2.
At the opposite end of the tube there is provided similar slits 9
defining wall sections 12 which instead of being depressed inwardly
into the interior of the tube 2, are caused to project outwardly as
shown so that they project beyond the outer periphery of the tube.
Thus, as illustrated in FIG. 1, the resilient portions 12 serve to
resiliently engage the inner peripheral surface 13 of a roller
assembly 14 slipped over the outer periphery of the tube. It has
been found that sufficient frictional resistence exists between the
surfaces of the roller assembly or the brush and the associated
displaced members 4 and 12 of the tube to permit rapid rotation of
the tube and the attendant brush or roller so as to effect cleaning
of the brush or roller through the effect of centrifugal force.
To effect such rotation, there is provided at one end of the tube
2, a cap structure 16 having a cylindrical wall 17 in the inner
periphery 18 of which is proportioned to snugly engage the outer
periphery 19 of the tube. The member 6 is fabricated from
appropriate synthetic resinous material and if desired may be
adhesively secured to the end of the tube. It has been found
preferable however that the proportions of the inner peripheral
surface 18 and the outer peripheral surface 19 of the tube be
formed so that the member 16 may be retained on the tube through
frictional resistance.
Mounted through the member 16 is the shank of a cap screw or bolt
21, the head 22 of which lies within the member 16 and the shank of
which passes outwardly therefrom along the central axis of the
tube. An appropriate washer 23 and lock nuts 24 are provided to
lock the shank to the member 16. The portion of the shank 21 that
extends beyond the lock nuts 24 thus constitutes a stub shaft and
may be used to attach the device in the chuck 26 of a drill motor
27. As shown in FIGS. 3 and 4, when so mounted, whether the brush
be supported within the tube and retained by the wall portion 4, or
whether the roller assembly 14 be supported on the tube by the
portions 12, actuation of the drill motor 27 will effect rotation
of the brush or the roller, which has preferably been immersed in a
solvent appropriate for the paint being used. When the device is
rapidly rotated within the confines of a container 28 as shown,
centrifugal force causes the paint particles retained between the
bristles and in the felted roller to dislodge themselves and fly
radially outwardly out of the brush or roller. Thus, it is possible
to clean a brush or roller in a matter of seconds as opposed to the
laborious process normally followed by most painters.
While the elongated tubular member has been described as fabricated
from a synthetic resinous material, it will be obvious to those
skilled in the art that it may be made from many suitable
materials. Additionally, while the strips 4 and 12 are shown as
spaced apart by a section of the tube from which they are struck,
these strips may be continuous onepiece members formed in an
undulating pattern so that one portion projects inwardly and
another portion projects outwardly.
