2 Claims. (Cl. 15-230) My invention relates to an improved paint roll and paint roll mounting.

More particularly stated my invention relates to a paint roll and paint roll handle mounting so constructed and designed as to facilitate a cleaning operation for the roll clothing.

One of the principal objects of'my invention is the addition to a somewhat conventional paint roll mounting of a device so located as to facilitate the spinning of the roll in a centrifugal cleaning operation, such device in its preferred form being incorporated permanently in the roll and mounting structure so as tobe available at all times and even with the simplest of accessory equipment.

In the drawings:

Figure 1 is a plan view of a paint roll and its handled mounting made in accord with one form of my invention, a portion of the roll and roll clothing being broken away to show portions thereof in section.

Figure 2 is a section through an alternative form of paint roll cylinder mounted upon a shaft 10 of a paint roll frame, the section being comparable to a section on line 2-2 of Figure 1 but showing an alternative bulkhead and cylinder surface construction.

Figure 3 is a fragmentary detail in section of an alter native spinner hub for the type of roll mount shown in Figure 2.

Figure 4 is a diagrammatic view partly in vertical section and partly in elevation showing the application of motive power to a hub of a roll as it may be held in a container in a cleaning operation.

It is somewhat conventional to provide a paint roll with a handled mounting as shown in a typical example illustrated in the U.S. Letters Patent to Thomas et al., No. 2,520,863, issued August 29, 1950, which-shows a straight shaft such as the shaft provided by the applicant at 10 upon which the roll 11 is mounted for rotation. The straight shaft 10 has a frame extension 12 approximately at right angles to the straight shaft and of sufficient length so that the continuation of the frame at 13 may parallel the straight shaft 10. Hereinafter I shall refer to the configuration of the shaft 10, frame member 12 and frame member 13 as being J shaped. Extending at right angles from the frame portion 13 is the frame portion 14 upon which handle 15 is mounted. As to these features, my paint roll and paint roll mounting is conventional except as to the features now to be described.

It has heretofore been suggested that a paint roll which has the usual lambs wool or pile fabric applicator surface or clothing material 16 upon a revoluble cylinder 17 mounted upon a shaft such as the shaft 10, may be cleaned by centrifugal forces, and the usual procedure is to remove the roll 11 from shaft 10 and mount it in a fixture so that it may be spun upon its axis at relatively high speeds in a cleaning operation. In keeping with my invention it is possible, as shown in my draw- United States a Patent. Tice ings, to spin the roll 11 in a centrifugal cleaning oper- Patented Nov. 24; 1959 ation without removal of theroll 11 from the shaft 10 and in fact without disassembling any of the mechanical elements of the roll and roll mount shown in Figure 1.

In accord withv my invention I provide an elongated shaft 10 upon which the roll 11 may be mounted and I provide adjacent the frame portion 12 and between the roll 11 and such frame portion, a device which will turn with the roll and which may be used as a manual or power application element to induce the necessary rapid rotation of the roll in the cleaning operation. As indicatedin Figure 4, a relatively deep container 20, having 'an inturned upper flange 21 to prevent spillage, is used to provide a container for cleaning liquid and to provide a receptacle in which the roll may be spun in a centrifugal cleaning and drying operation. The J shape of the shaft 10, and frame portions 12 and 13 make it possible for the user to hold the handle 15 during a motorized drive of the roll 11. A motor 22 with a friction disk 23 on its shaft 24 may be used to apply rotative power frictionally to a friction drum 25 forming a part of the roll assembly. In this cleaning operation as thus motorized,

the user may grasp the handle 15 with one hand and the stationary frame portions 12 and 13 to hold the drum 25 against friction disk 23 as will be readily apparent from an examination of Figure 4.

If motorized means such as shown in Figure 4 are not available, an ordinary knurled sleeve 26 forming part of the assembly of the roll 11 may be used at a time when the roll 11 is positioned in container 20 and the palms of the hands of the user may be disposed on either side of the sleeve 26 in an equal and opposite reciprocation of the palms of the hands against the sleeve to cause the roll 11 to spin.

It will be noted that the shape of the shaft 10 and frame portions 12 and 13 is such that the manual rotation of the sleeve between the palms of the hands of the user is not impeded and because the sleeve 26 is of smaller diameter than the exterior diameter of the roll 11, a considerable surface speed of rotation of the roll surfacing material 16 is possible.

In Figure 3 I have shown in greater detail a mounting of a paint roll upon shaft 10. This mounting includes a roll sleeve 30, a hub 31 and an exterior roll cylinder 17 hearing snugly against the cone shaped surface 32. The extended portion of the hub 31 at 33 is grooved at 34 for a belt drive to any form of motorized apparatus such as that shown at 22, 23, 24 where the disk 23 may be grooved to receive a belt (not shown). Figure 2 shows at the extreme right a hub oppositely conically shaped to receive cylinder 17, and it will be noted that in Figure 2 the sleeve 30' of the roll mount extends well beyond the hub as shown in Figure 3, and it is this extended portion which provides the knurled end 26 as shown in Fig. 1. It will be further noted that to prevent the cramping of the knurled sleeve 26 at the bend of the shaft 10, a friction cup nut 35 is threadedly secured to the end of the sleeve 30 and a headed screw 36 threaded into a bore 37 in shaft 10 limits the movement ofthe sleeve 30 to the right as seen in Figure 2.

Other means for imparting rotative motion to the roll would include a wrap around string or cord for a pulley 33 or knurled sleeve 26' to be pulled by hand, or recipro cated in boy scout fashion with a bow or other tension member.

From the above description it will be seen that a relatively simple mechanical mounting for a paint roll and the extension of a relatively small diameter sleeve 26 facilitates the manual or power rotation of a paint roll in a centrifugal cleaning operation.
