APPARATUS FOR CLEANING BRUSHES Filed Feb. 7, 1958 FIG. .1.

INVENTOR.

JOSEPH /v. knee/s,

Un sd st tePatsm 0. Tie

This invention relates to a brush holder. More specifically, the instant invention deals with a. brush holder 7 adapted for connection with a rotatable power source for the purpose of spinning the brush at a high rate of speed in order to clean the bristles thereof.

Among the objects of this invention is to provide a brush holder of the class described which is especially adapted for use in cleaning paint brushes.

Another object is to provide a brush holder intended for use in the following manner: First,-the brush to be cleaned is secured to the holder; second, the holder is mounted in a power source (for example, a power drill); third, the brush is dipped into a suitable solvent and finally, the brush is rotated at a high speed within an enclosed area thus throwing off the paint and solvent by centrifugal force.

Still another object is to provide a brush holder formed in such a manner that the brush will be securely held during the spinning process, and yet be easily demountable when the process is completed.

Among the further objects and advantages of this invention is to provide a brush holder constructed and assembled in accordance with the teachings thereof, the brush holder being inexpensive to manufacture, simple in construction and durable in use. I

Other and further objects will become more readily apparent from a consideration of the following specification when read in conjunction with the annexed drawing, in which:

Figure 1 is a side elevational view of a 'brush holder falling within the scope of this invention, having a brush mounted therein for cleaning and being releasably secured to a hand power drill of a conventional type;

Figure 2 is an enlarged, detail cross-sectional view of the brush holder shown in Figure l, the view taken substantially along the vertical plane of the line 22 of Figure 1, looking in the direction of the arrows;

Figure 3 is an enlarged top plan view of the brush holder dismounted from the power source, but having the brush in place; and i Figure 4 is an enlarged detail cross-sectional view taken substantially on the horizontal plane of line 4-4 of Figure 2, looking in the direction of the arrows.

Referring now more specifically to the drawings, reference numeral 10 designates, in general, a brush holder constructed and assembled in accordance with the teachings of this invention. The brush holder 10 is seen to comprise an elongated, substantially hollow, cylindrical main body portion 12, constructed of rubber or any other equivalent resilient material, having an open end 14 and an opposed substantially closed end 16 and, as is seen in the drawing, a substantially annular boss 17 formed therearound adjacent the closed end 16.

The closed end 16 is provided with a substantially circular opening 18, in coaxial alignment with the major axis of the main body portion 12, the opening 18 extending transversely therethrough for a purpose to be described below. The main body portion 12 also has .-a

2,931,661 Patented Apr. 5, 1960 series of spaced, alternate, longitudinally extending lands 19 and grooves 20 formed on the outer surface thereof for the purpose of providing a firm grip when inserting or withdrawing a brushfrom the holder 10. The lands 19 and grooves 20 extend longitudinally down the outer surface of the main body portion 12 from the boss 17 thereof to the open end 14.

In assembling this device, a substantially cylindrical spindle member 22 having a substantially disc-shaped base 24 is fitted through the opening 18 in the main body portion 12, the opening 18 being of sufficient size to allow the passage of the spindle member 22 therethrough, but not of suflicient size to allow the passage of the disc 24 which is of substantially the same outer dimensions as the diameter of the inner side of the main body portion 12 adjacent the boss 17. The spindle 22 is provided with a threaded portion 26 adjacent the portion thereof which passes through the opening 18. A washer 28 of conventional design is placed around the spindle 22 and bears against the closed end 16 of the main body portion 12, the washer being held in place by a hexagonal nut 30 which is threadedly connected to the threaded portion 26 of the spindle 22.' It may be observed from the drawings that the base 24 and the washer and nut 28, 30, cooperate to releasably connect the main body portion 12 to the spindle 22.

A substantially cylindrical plug member 32 having a bore 34 extending therethrough and coaxial with respect to the spindle 22 is press-fitted into the inner surface of the main body portion 12 and rests against the closed end 16 thereof.

In making use of the brush holder to clean a paint brush, the handle 36 of the brush 38 to be cleaned is pressed into the open end 14 of the main body portion 12 and the spindle 22 is secured by conventional means to the chuck portion of a hand drill 40 or other rotatable power source. Because the main body portion is constructed of a resilient material, the resiliency thereof will tend to grip and hold the brush 38 Within the main body portion 12 of the holder 10. Furthermore, when the power source is activated it has been found that at the initial rotation of the brush the body 12 is slightly contracted and as the device 10 is rotated at a high rate of revolutions per minute, a suction is formed within the main body portion which will, along with the aforementioned elasticity, secure the brush therein during the cleaning process.

It should be noted that where it is desired to clean a brush having a substantially conical handle (not shown), the tip of the handle of such a brush is inserted into the bore 34 of the resilient plug 32 and thus a still further holding means is provided.

Having described and illustrated one embodiment of this invention, it is to be noted that this embodiment is given only by way of example and that this invention is to be limited only by the scope of the appended claims.

What is claimed is:

1. In an accessory device for a rotary drill or the like, said device being adapted to releasably grip the handle portion of a brush for spinning in the drill; a brush handle holder comprising an elongated, resilient, substantially hollow main body portion, said main body portion including an open end and an opposing closed end; and means connected to said closed end for the connection of said device with said drill.

2 A brush handle gripping device adapted for use with a rotary power source including a chuck, said device comprising an elongated main body portion formed of a resilient material and having a longitudinally extending cavity formed therein adapted to receive said brush handle; and means on said device for. effecting the release able connection thereof with said power source.

Eg s-1,001-

3. A brush handle gripping device as defined in claim 2 wherein longitudinal re-inforcing means are provided on the exterior surface of said main body portion.

4. A brush holder adaptedtq hold the handle; portion of a brush, said handle portion including a p'ointed tip; and said brush holder being adapted. fontuse' with a portable electric drill which includes a chuck, s aid holder comprising an elongated, hollow main body portion formed of a resilient material, said main body' portion having an elongated handle-receiving cavity,extending trom an open end thereof to an opposing closed end; means adjacent said closed end for connection of said holder in said chuck; andan annular plug member in said cavity adjacent they closed end of the main body portion, said plug having an opening formed therein adapted to grip said pointed tip of said brush.
