BRUSH.

Application filed February My present invention relates to improve ments in brushes of the type used for floor and street sweeping, provided with a handle, and as a rule manipulated by the use of two hands of the sweeper. In such brushes the end of the handle is generally grasped by onehand, and in the control of the movement of the brush in connection with the hand which grasps in intermediate portion blisters and callous places to develop with consequent discomfort and inconvenience.

The primary object of my invention is the provision of means on the handle, and preferably located at its free end, which will compensate for the relative movement of the hand and handle, prevent rubbing of the hand on the handle, and insure convenience in the operation or strokes of the brush when manipulated by the sweeper.

The invention consists essentially in pro viding an anti-friction, rotatable bearing member, as a head preferably located on the free end of the brush-handle and adapted to be h novel combinations and arrangements of parts in connection with this rotatable head as will hereinafter be more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete. example of the physical embodimentof my invention where in the parts are combined and arranged according to the best move I have thus far de vised, together with a slight modification thereof, showing the practical application of the principles of the invention.

Figure 1 is a perspective view of a brush embodying my invention. 7

Figure 2 is an enlarged sectional View of the bearing head showing its relation to the brush or broom handle.

F igure 3 is a perspective view of the ferrule or bearing sleeve used in the head.

Figure 4 is a sectional view showing a slight modification of the invention.

In carryingout the invention I utilize a brush or broom of the type illustrated in Figure 1 of the drawing in which the brush a head 1 is equipped with the usual bristles 2 and located in position transversely of the grasped in the hand or fingers, and in 16', 1926. Serial 210,38541.

handle 3. The handle is secured in the brush head in any suitable manner and inclines upwardly therefrom as shown, with its free end a used as a bearing end for the hand grasp 5. The hand grasp is preferably made in the shape of a spherical knob or rounded bearing head of convenient size to a be grasped by the hand or by'fingers and a thumb of the hand, andit is retained on the handle and adapted to rotate on an axis forming a continuation of the longitudinal axis of the stationary handle.

The bearing head or knob is fashioned with a radial socket 6, and a smaller opening or bore 7 is formed as a continuation of this socket. The socket as shown in the drawings is designed to fit over the end a of the handle, and the opening 7 is designed to accommodate a screw 8 that is threaded into the head 4: of the handle 3. The head 9 of the screw is located in a countersunk opening of the hole 7 in order that it may not form an obstruction on the-surface of the bearing head or knob, and to retain the knob on the end of the handle.

Between the screw head and the handle head, and encasing the smooth stem of the screw is located a metal ferrule or sleeve 10 which is fashioned at its inner end with a mushroom-shaped or taperedhead 11, and on the face of the end of the handle is located a perforated washer 12 through which the screw is passed. By the utilization of this construction the hearing head 5 isprovided with a bearing which extends sub-- stantially through the head and includes the wall of the socket in engagement with the handle together with'the ferrule or sleeve on the screw, and the bearing head is retained with stability on the handle but permitted to freely turn thereon when grasped by the hand or fingers and thumb, as the broom or brush is manipulated.

The mushroom-shaped or tapered head 11. of the ferrule, which is resilient, permits the screw to be turned to bring the bearing head into such close relation to the handle as to prevent detachment therefrom, and at the same time permits the necessary rotary niovement of the'bearing head onthe hand e.

In some instances the handle 3 of Figure 4 is of such a large size as to preventattachment of the bearing head of. the size shown in Figure 2. In such instance the end 4? of too 2. The combination with a brush handle and an attaching screw secured thereto, of a knob having a socket and a screw opening 15 aligned therewith and fitted over the handle, a bearing ferrule encasing the attaching screw Within said opening a perforated washer on the end of the handle, and a mushroom-shaped resilient head on said fer- 20 rule engaging the Washer.

In testimony whereof I affix my signature.
