Description
This invention relates to an improvement in paint brush supports,
and deals particularly with a support for a paint brush which will
hold it suspended over the paint pail when not in use.
Over the years, a great many devices have been produced for
suspending the bristle end of a paint brush over the paint pail
when the brush is not in use, and for scraping the excess paint
from the brush during the painting operation. These devices vary
quite considerably in form and shape. In some instances, the
devices comprise a paint pail cover which extends only partially
over the pail, and which may be used to form a brush support and
scraper. In other cases, such devices may comprise a wire extending
across the pail and having arcuate ends which are engaged in the
groove which normally encircles the top of the can and which is
designed to accommodate a downwardly projecting ridge on the paint
pail lid.
While these previous devices are undoubtedly of assistance in
accomplishing the desired result, I have found that they are
deficient in certain respect. For one thing, supports which extend
across a paint pail and support the bristle end of the brush
accumulate paint, and over a period of time build up a coating
which is adpt to chip off and fall down into the paint, causing
hard lumps of hardened paint which mix with the paint and must be
removed from the surface being painted. Furthermore, for the most
part, the previous devices depend upon a frictional engagement of a
portion of the device in the grooves surrounding the opening of the
paint pail, and which is designed to accommodate the downwardly
extending circular flanges of the cover, and which may be easily
forced from place during the painting operation. One of the
purposes of any such device is to prevent the paint from collecting
in this groove, both for the reason that paint collecting in the
groove will harden and prevent the cover from securely closing the
can, and also for the reason that a build up of paint in this
groove eventually causes the paint to overflow and run down the
outer walls of the can.
I have found that the previous difficulties may be eliminated to a
large extent by using a helical spring as the brush support. When
the brush is rested upon such a helical spring, the paint tends to
drain down from the brush and unto the coils of the spring.
However, when the spring is removed, it may be stretched and
allowed to return to its normal position, and any paint which is
dried upon the spring tends to flake off due to the distortion of
the spring coils. As a matter of fact, even after the paint has
dried, the flexing of the spring will usually distort the paint
coating on the springs efficiently so that the paint will flake off
so that the spring is relatively free of paint when it is
reused.
Another feature of the present invention resides in the provision
of a means of retaining the brush support on the pail when it is in
use. If the brush support loosens on the pail, not only is the
brush liable to drop into the pail, but also the supporting device
itself is likely to fall from place dropping to the floor or other
surface over which the pail is suspended.
Most paint pails are provided with bosses designed to accommodate
the handles by means of which the pail may be carried. These bosses
are hollow, and are provided with apertures spaced outwardly from
the walls of the pail in which the ends of the handle are engaged.
I have found that by engaging the ends of the brush support in
these bosses, the brush support is actually supported by means
spaced from the edges of the pail and which are less likely to
become disengaged during the painting operation.
Another feature of one form of construction of the device lies in
the fact that the helical spring which supports the paint brush is
readily adjustable relative to the means connecting the spring to
the handle supporting bosses which have been described. The ends of
the helical spring may be adjustably connected either to another
spring or to a wire clip, either of which may be used to tighten
the tension of the spring by merely winding the point of connection
helically along the spring toward the center thereof. As a result,
the device may be used to fit upon pails of different diameters
without difficulty.
These and other objects and novel features of the present invention
will be more clearly and fully set forth in the following
specification and claims .
In the drawings forming a part of the specification.
FIG. 1 is a perspective view of the top of a paint pail showing a
brush support which comprises a helical spring.
FIG. 2 is a vertical sectional view through the pail shown in FIG.
1 showing the manner in which one end of the helical spring may be
supported.
FIG. 3 is a view similar to FIG. 2 but showing helical spring means
used for connecting the brush supporting spring to the external
boss on the can.
FIG. 4 shows a simpler form of device which does not include the
advantages of the helical spring, but does include the novel means
of attaching the brush supporting means to the pail.
FIG. 5 is an elevational view of the brush supporting means shown
in FIG. 4.
FIG. 6 shows a second modified form of construction in which the
brush support comprises merely an elongated helical spring having
hook ends, the spring being designed to extend diametrically across
the top of the can, and the hook ends of the spring being designed
to engage in the handle supporting bosses on opposite sides of the
pail.
The brush supporting means A which is indicated in FIGS. 1 and 2 of
the drawings, is designed to extend diametrically across the top of
the paint pail B. The paint pail B as is indicated in FIG. 2 of the
drawings, usually include a cylindrical wall 10 having a bottom
closure which is not illustrated in the drawings, and having a
ring-shaped member 11 at its upper end which is crimped to the top
of the wall 10 as is indicated at 12, and which includes an
inwardly extending flange 13 connected to a generally U-shaped rim
portion 14 which terminates at its inner edge along a rolled edge
15. The U-shaped portion of the ring forms a groove 16 which is
normally designed to accommodate a downwardly projecting U-shaped
ring on the can cover. Due to the normal resilience of the material
used, this particular arrangement has been found very effective for
tightly sealing paint cans. On the other hand, the groove 16 tends
to form a natural receptacle for paint, as excess paint is usually
wiped from the brush such as the brush C indicated in FIG. 4 of the
drawings, and some of the paint usually drains into the groove 16
until this groove becomes filled or becomes overflowed. If the
painter is sufficiently expert to recognize the problem, the
painter will constantly swing the tip end 17 of the brush level at
a minimum. However, with a less experienced painter, the groove 16
tends to fill with the paint, and it the painting operation
continues over a sufficient length of time, the paint will become
hard in the groove 16 and will prevent the tight sealing of the can
lid.
The can D is also provided with a pair of diametrically opposed
bosses 20 which project radially from the surface of the can, and
which actually comprise hollow sleeve 21 having an axially
apertured outer wall 22 which is often inwardly and indented as
indicated in FIGS. 2 and 3 of the drawings. The handle of the pail
B usually comprises a generally semicircular loop 28 having hook
ends which engage through the apertures 23 in the outer walls 22 of
the bosses 20.
The brush support A indicated in FIGS. 1 and 2 of the drawings
includes a helical coil spring 24 connected at opposite ends to the
angularly extending anchoring brackets 25 designed to connect the
spring 24 to the pail B. The brackets 25 each include a loop end 26
which is threaded between the convolutions of the spring 24 at one
end thereof. Each arm of bracket 25 includes a generally
horizontally extending arm portion 27, and a downwardly extending
arm portion 29 connected thereto and terminating in a hook end 30.
The angle between the arms 27 and 29, or the resiliency of the
bracket itself, permits the hook end 30 to be engaged in the boss
20, while attached at its other end to one end of the spring
24.
FIGS. 3 of the drawings shows a slightly modified form of
construction in which a helical spring 32 is substituted for the
bracket 25. The helical spring 32 is provided with a looped end 33
adjustably engaged with the end of the transverse spring 24. The
spring 32 also has at its opposite end a hook shaped portion 34
which is designed to engage in the aperture 23 of a handle boss 20.
Obviously, the spring 32 may be substituted for the bracket 25
either at one or both ends of the spring 24.
The structure shown in FIGS. 4 and 5 lacks certain of the
advantages of the previously described construction in that the
member which acts as a support for the brush C comprises a straight
wire member rather than a helical spring as is preferred. As is
indicated in FIG. 5 of the drawings, the support D indicated in
these figures includes a crossmember 34 which is of proper length
to extend across the open upper end of the pail B, and includes
arms 36 extending downwardly from opposite ends of the member 35.
The downwardly extending arms 36 are provided with hook ends 37
which are designed to extend into the bosses 20 on opposite sides
of the pail to secure the paint brush support B in place.
FIG. 6 of the drawings shows another modified form of paint brush
support which is indicated in general by the letter E. This device
comprises merely an elongated unitary helical spring 40 which is
provided with hook ends 41. The spring 40 is of sufficient length
to extend over the top of the paint pail, downwardly along portions
of opposite sides thereof, and to permit the hook ends 40 to engage
in the bosses 20 on opposite sides of the pail. This structure,
while simple in nature, permits a single unitary spring to serve as
the brush support and also as a means of holding the brush support
to the pail.
In accordance with the Patent Statutes, I have described the
principles of construction and operation of my improvement in paint
brush supports, and while I have endeavored to set forth the best
embodiment thereof, I desire to have it understood that changes may
be made within the scope of the following claims without departing
from the spirit of my invention.
