Among the purposes and objectsof. my inven- A brush rotating means which alternates the direction of motion at certain intervals.

A handy, convenientpainters accessory. A resilient holder and reverse motion shockabsorber. A clutch and adjusting means for it which also closes the top of thecan to preventsplashingp A spray proof can closure and brush holding spindle for revolvingthe, brush in the can.

I accomplish the above and other objects by the construction herein set-forth-and shown in the accompanying drawings forming a part hereof, in which: v v A Fig. 1 is a perspective view showing'one of the applications of my device.

Fig. 2 is fragmentary detail of the spindle and clutch. l i i Fig. 2A is a fragmentary detail of a modificatio of one of the jaws of the clutch. i

Fig. 3 is adetail cross section at 3-3 Fig. 4.- Fig. 4 is a fragmentary cross section of the cover. i Fig. 5 is an elevation of one of the segmental gears. 1- Similar reference characters refer to similar parts throughout the several views of the drawing and in the specifications to follow. 1

My invention cleans the paint from the bristles of paint brushes by a whirling or centrifugal motion, by revolving the brush, first in one direction and then the other. moving the device from the can in which the cleaning fluid is kept to an empty motion is repeated.

. In this, my disclosure, I have not attempted to show all the modifications which are possible to make within the scope and concept of my inventionbutrather to describe, in detail, a-preferred of paint cans which. are nearly universally used at this time, particularly in the sizesone gallon to a* device particularly The brush is dried by reone where the Claims. (01. 134-143) ,2 and less carried by, hardware and paint stores. Snuglyfitting the inner diameter ofthe opening 2 in the top of the can, I have provided the depending flange 3 which may be one of a plurality of such flanges secured to or formed integral with the cover plate or base 14.; The several flanges 3. are suitable to engage the tops of paint cans of,

The base 4 not only serves as ameans detachably securing my device to the paint can-but also serves to cover'the canjduring operation to prevent paint or other liquid and/or pigment from being sprayed :or thrown out. Thebase 4 also is provided with the frame 5 which supports the bearings 6 and 1 and the movingparts.

The vertical bearing, 6 receives the journal 8 l of the spindle 9, the upper end ID of which is securedto the bevel'pinion II .which alternately meshes with the segmental racks l2 and I3 which are sodisposed on the drive shaft l4 that one of said racks meshes on one side of said pinion;

then after disengaging said pinion, the other rack engages the pinion onthe opposite side, thereby causing the spindle to revolve first in one direction then in theopposite direction.

The same result is also obtainable by substituting' friction surfacesfor the teeth'l5 of the pinion II and the teeth It and I! of the segmental racks' l2 and l3.- 1 Q Secured to .the spindle 9 at the end opposite thepinion ll is the1chuck l8 comprising the spring retracted arms I9 which normally diverge from the hub 20 when the chuck is open and are substantially parallel when the chuck is closed by forcing the slidable collar down over the arms.

Each arm is preferably providedwith the resilientpads22 of neoprene-sponge or othersuit+ able material which is adapted to withstand the oil and cleaning liquid whicnmay be on the handle 23 of the bru-shzll which maybe held in the chuck and revolved by the mechanism described above.

In Fig. 2A I have shown the modified arms I8" conform to the longitudinal variations of shape and size-and also provide resiliency in absorbing some of the shock of the sudden reversing of motion of the spindle 9 resulting from the alternate engagement of the segmental racks l2 and I3 with the pinion II or the modified friction devices and surfaces (not shown) which may be substituted for the pinion and segmental racks.

In Fig. 2A, I have shown a modification of the chuck H5 in which the arms l9 are shown detachably secured to the hub 20' by means of the screws 2i. The arms l9 may be flat springs and thus are detachably secured to the hub at one end and are permanently secured to the heavy, more rigid lower portion of the arms to which the resilient pads 22 are secured.

The collar 2| may, in some cases, be, modified by being threaded and the arms also may be provided with threads to receive the'threaded collar to assist in forcing the collar to clamp the arms on the brush handle or other device which is held in the chuck.

The base 4 is provided the center aperture 3| which is of sufficient diameter to receive the arms IQ of the chuck when in their open position as may be seen by referring to Fig. 2 of the drawings. The collar at its lower position of travel over the arms of the chuck is partly shown in broken lines.

The base 4' is preferably provided with an upwardly projecting ridge 32 surrounding the collar 2| and catching any liquid or spray which may escape between the under face 33 of the collar and the top surface 34 of the base 4.

The collar is provided with the outward extending flange 35 which serves as a, handle or knob for sliding the collar on the chuck arm-s and the lower flange 36 which serves as a cover over the aperture 3| as well as to provide the extended under surface 33 for the collar.

A downwardly projecting ridge 3'"! is provided around the aperture 3| to reduce the spray leakage through the aperture around the chuck and handle.

. The bristles 38' of the brush 25, when revolved, are thrown outwardly as shown in Fig. I of the drawings, thus most effectively releasing the liquid and pigmentsin cleaning. The bristles return to their normal vertical position, then rubagainst each other and fly outwardly away from each other at each stop or reversal of the direction of travel of the revolving brush, chuck and spindle.

The drive shaft I4 is shown as being provided with a crank 38 or other means for revolving said shaft in one direction or both directions. The racks l2 and I3, however, will reversethe motion of the spindle 9 while the drive shaft continues to revolve in one direction. It is thus unnecessary to reverse the motion of the drive shaft such as by turning the crank in the opposite direction or obviously by providing other mechanical devices to revolve the drive shaft in one direction, then to revolve it in the opposite direction.

The size and relation of the parts may vary to suit the particular service to which my device may be suited.

The foregoing specifications of the preferred embodiment of my invention are, by this disclosure, a contribution to the better understanding of the following claims which setforth my invention and for which this is my Letters Patent.
