PAINT IMPLEMNT CLEANING DEVICE Filed May 10, 1962 3 Sheets-Sheet 3 INVEN TOR.

ie States This invention relates to a cleaning device and more particularly to a device for cleaning paint applicators such as brushes, rollers and the like.

This application is a continuation-in-part of application Serial No. 115,763, tiled lune S, 1961, now abandoned.

lt has been common practice to clean paint brushes by suspending them in a container lled with a solvent or detergent and then cleaning with water after the solvent or detergent action is completed. Any agitation has been accomplished by manually moving the brushes through the solution. In the case of cleaning rollers, the fleece cover is removed and placed in the solvent and then washed.

The present invention is directed to a device in which the applicators, whether they be brushes or rollers are suspended in the cleaning solution and are agitated therein and can be moved in their suspended position from one container to the other having different cleaning solutions therein. The device is adaptable for cleaning the entire paint roller without removing the cover.

An object of this invention is to provide a device in which paint brushes and rollers can be suspended in a cleaning solution and manually agitated therein in such manner that the entire assembly can be removed from one cleaning solution to another.

Other objects of the invention will be obvious from the attached drawing in which FlGURE l is an elevational view in section showing the device of my invention with paint brushes positioned therein;

FIGURE 2 is a top plan View of the device shown in FlGURE l; and

FIGURE 3 shows the same type container with a conventional roll applicator suspended therein.

Referring to FIGURE l there is shown a container 2 of the bucket type, which is preferably made of spun aluminum so as to avoid a seam along the side and in the area where the side wall and the bottom adjoin. It will be understood, of course, that other types of containers may be utilized satisfactorily in carrying out this invention. A bottom support member 3 rests on the circular bottom of the container 2 so that it spans substantially the entire diameter of the container. The ends of the support 3 are rounded at 4 to conform to the arc of the wall of the container. An upstanding bearing stud 5 is attached to the center of the support 3 by means of a screw 6. The support 3 is so shaped that the ends 7 are bent slightly downwardly so that the central portion 8 of the support is positioned above the bottom 9 of the container a distance sufficient to prevent the head l@ of the screw 6 from engaging the bottom of the container. In the embodiment here illustrated the support 3 has adjustable ends ll secured thereto by means of the clamping screws l2 passing through slots 13 in the support 3 and being in threaded engagement with the end l1. With this arrangement the screws l2 can be loosened and the ends l1 moved in or out as the case may be to conform to the size of the container 2.

A top support 14 spans the top of the container 2 across a diameter preferably parallel to the bottom support 3.

teilt This top support ld is secured to the container by means llbjflS Patented Jan. 7, 1964 erably at an angle of ninety degrees with respect to the long dimension of the top support le.

The brushes to be cleaned are secured to a shaft 13 by means of a bolt 19 and thumb screws 2t?. The bolt passes through the brushes and a hole in the shaft 18. The shaft 13 is hollow to receive the stud 5 secured to the bottom support 3. The longitudinal opening 2l in the center of the shaft is suiciently large to receive the stud 5 with a minimum of friction. The stud 5 is provided with a shoulder 22 on which the bottom surface 23 of the shaft 18 is supported.

The top of the shaft 1S has an extension 24 which is received in the notch 317. The two slidable members 25 are attached to the top support ld by means of screws 26 which pass through slots 27 in the members 25. Each of these members 25 is provided with an opening 2S which is of a width equal to the diameter of extension 24 and is of a depth slightly greater than one-half the diameter of extension 2d. These two openings 23 are at right angles to the notch 17. When the shaft extension 24 is in position in the notch f7, the sliding members 25 are pushed toward one another until their edges 29 abut. In this position the screws 26 are tightened, clamping the two slidable members to the top support ld holding the shaft l in substantially vertical position in the center of the container 2. ln order to insure that the sliding members 25 will not become loose due to continual rotating of the shaft 1S there are provided two studs 30, one in each sliding member which are threaded to each sliding member 2S and enter into holes in the top support ld. The arrangement is such that when the sliding members 25 are in abutting relationship the holes in the sliding members 25 and the top support ld are in alignment so that the studs 3@ enter the openings in the support 14 and prevent movement of the sliding members 25. A device such as a hand crank 3l is attached to the top of the shaft extension Z4 for turning the shaft and the brushes 32 attached thereto. The brushes should be preferably so positioned that the longitudinal axis through the handle of the brush is not parallel to the shaft i3 but is at a relatively wide angle with respect thereto so that for each revolution the brush will travel through a wide arc in the solution. The brushes are prevented from assuming a position parallel to the shaft ES by means of collars 33 located between the brushes 32 and the shaft l. These collars are provided with sharp tines 34 which penetrate the wood part of the brush handle. When the thumb screws Ztl are tightened on the bolt 19 they clamp the brushes 32 thereon and this clamping action prevents the collars 33 from turning on the bolt 19. With this arrangement the brushes can be oriented at the proper angle and tightened in that position so as to attain the optimum benefit of the path of travel of the brushes in the cleaning solution.

The top support 14 is also provided with a pivoted support 35 which is attached to the suport for rotary motion with respect thereto by means of a stud 36. This support has an opstanding member 37 which is substantially the same size as the stud 5 attached to the bottom support 3. When the brushes are removed from the solution the support 35 is pivoted one hundred and eighty degrees from the position shown in FGURE l and the shaft l@ is placed over the upstanding member 37 so that the assembly is supported in this manner over the container permitting the cleaning solution to drain from the brushes back into the container. In the modification shown in FIGURE 3, the same device is used for suspending a conventional paint roller in cleaning solution by placing the shaft 3S of the handle supporting portion of the roller in the notch 17 and sliding the members 25 into position surrounding the shaft 3% holding the same rmly in position in the center of the container. The sliding members 25 are then locked in this position by means of the locking studs Se. This device can then be agitated by merely turning the handle 39 between the palms of the hands.

in operation, the brushes to be cleaned are attached to the hollow shaft TLS by means of the bolt and thumb screw assembly ll9 and 2i) and the brushes are rotated about the bolt h3 until the longitudinal axis through the handle is at a relatively wide angle with respect to the shaft i8. When the brushes have assumed this position the thumb screws 28- are tightened so that the tines 3-'3- of the collars 33 penetrate the wood of the handle and hold the brushes at this angle. The bottom support 3 is then tipped slightly to one side so that the bottom of the shaft 18 can be placed over the stud 5. This can be accomplished by merely pushing the stud with the bottom of the shaft il@ until the two are in proper axial alignment for placing the shaft over the stud. When the shaft is so positioned, the entire assembiy is rotated about the pivot point provided by the bottom support 3 until the central shaft L; is in a vertical position with the extension 24. in the center of the notch f7. Slidable members are then moved in a direction parallel to the long dimension of the top support 14 until they abut one another with the openings 23 therein surrounding extensions 24 and forming a top bearing therefor. The sliding rnembers 2S are locked in this position by means of the studs 3G. The cleaning solution is then poured into the container and the brushes are agitated therein by means of turning a hand crank for a sufficient time to remove the paint from the brushes.

The supporting shaft i8 is then removed by sliding the members 2.5 away from one another permitting the extension 24 to be removed from the notch 17 and rotating the shaft f8 about the pivot point formed by the bottom support 3 a sufficient distance to allow the brush assembly to be lifted past the top support le. At this time the pivoted support 3S is rotated one hundred eighty degrees about the Stud and the shaft 18 is placed over the upstanding member 37 and in this position the cleaning solution remaining in the brushes can drain back into the container.

Similar containers can be provided with other types of solution and the assembly of the shaft i8 with the brushes and the handle can be placed in another container in the same manner as described. ln those cases Where only one container is available, different cleaning solutions can be placed in the same container sequentially until the proper degree of cleaning is effected.

lt will be clear from the above that I have provided a device which will simplify the cleaning of paint brushes and which will be highly useful for cleaning brushes at the scene of a painting operation.
