United States Patent O 3,562,837 PAINT ROLLER Stanley W. Baginski and Stanley W. Baginski, Jr., both of 189 E. 18th St., Brooklyn, N.Y. 11226 Filed Nov. 25, 1968, Ser. No. 778,654 Int. Cl. B05c 1/08 U.S. Cl. 15-230.11 2 Claims ABSTRACT OF THE DISCLOSURE A paint roller assembly comprised of a pair of paint rollers carried upon ball bearings supported on a shaft, and the ball bearings being enclosed within an oil reservoir that is designed to be leakproof regardless of the position of the paint roller assembly.

This invention relates generally to paint rollers such as are manually rolled across a surface during painting operation.

A principal object of the persent invention is to provide an improved paint roller which comprises a pair of paint roller units along a common axis which is connected between the roller units to an extending handle.

Another object is to provide an improved paint roller wherein the extending handle is interchangable so as to comprise either a straight or L-shaped handle so to afford maximum comfort to use in various areas.

Another object is to provide an improved pain roller comprising a dual roller that can be easily changed to a single roller by removing either one of the roller units, thus affording still further accomodation thereof so to be adaptable to use in various areas.

Yet another is to provide a paint roller wherein the roller units are carried upon ball bearings that are sealed Within an oil reservoir, thus giving a friction free movement and providing a long life against wear and break down.

Yet a further object is to provide a paint roller wherein the oil reservoir is designed to be leakproof against oil dripping therefrom, regardless of the angle or position of the paint roller.y

Other objects are to provide an improved pain roller which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efiicient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a side view of the invention shown partly in cross section.

FIG. 2 is a side view thereof shown in an alternate position, and shown secured to a modified type of handle.

Referring now to the drawing in detail, the reference numeral represents an improved paint roller according tothe present invention wherein there is a handle rod 11 secured to a post end of a T-fitting 12. The arm ends of the T-fitting are secured by screw threads to the ends of a pair of shafts 13 which thus are in axial alignment to each other, each shaft supporting a paint roller unit 14.

Each paint roller unit 14 includes a hollow arbor 15 mounted upon ball bearings 16 contained therewithin; the ball bearings being supported upon the shaft. The arbor comprises a cylinder having central cavity 17 which serves as an oil reservoir for lubricating the ball bearings. The arbor includes cylindrical side wall 18 and op- 3,562,837 Patented Feb. 16, 1971 posite end walls 19 and 20 integrally formed or leak proof sealed to the side wall 18. Accordingly the end wall 19 may comprise a cock plug seal tightly fitted to the cylinder end, while the end wall 20 compirses an integral element having a central opening 21 through which the shaft 13 extends. A sleeve 22 integral at one end with end wall 20 is of sufficient length so to prevent oil within the reservoir to run out of the opening 21 when the device is tilted as shown in FIG. 2 the sleeve thus extending higher than the depth of the oil. An oil fitting 23 such as a Gits oiler is seated in the end wall 20 so to allow refilling oil into the reservoir whenever needed. It will be noted that the end wall 20 is diametrically larger than the side wall 18 thus forming an outward flare or flange 24 all around for a purpose which will be explained herebelow.

A replacable paint roller sleeve 25 is fitted over the arbor, the sleeve being of relatively shorter length than the arbor. The wall 19 has a flange to retain the roller sleeve 25 on the arbor. The sleeve 25 is comprised of a core 26 slidable upon the arbor, and a lamb wool cover 27 around the outer side of the core.

It will now be evident that the lamb wool holds the paint while it rolls across a surface being painted. Any paint dripping from the sleeve 25 will be confined by the flange 24 from running down upon the shaft 13.

The handle rod 11 is threadedly securable to a straight handle extension 28 (as shown in FIG. l) or to an L- shaped handle extension 29, each of which has a handle hold 30 for being grasped within the hand.

In operative use, the device can be adjusted for convenient use in various different places. Either roller unit may be removed by unscrewing the shaft 13 from the T-fltting, and either handle may be employed. The device may be tilted to any angle without oil spilling from the reservoir.

While various changes may be made in the detail construction, it is understood that such changes will be within the spirit and scope of the present invention.

We claim as follows:

1. A paint roller assembly comprising a solid shaft having two similar paint rollers mounted symmetrically thereon in combination with a handle extending transversely from the shaft center, each of said rollers comprising a hollow arbor mounted rotatably on said shaft spaced from said handle, including ball bearings mounted between the shaft and arbor, and a roller sleeve mounted slidably on said arbor `wherein said arbor is of longer length than the sleeve, said arbor including an inner fiared end wall adjacent said handle of larger diameter than the general arbor diameter, and an outer end wall with a flange to retain the roller sleeve on the arbor, further including an oil sealing sleeve snugly engaging the shaft and extending integrally from the inner end wall for a predetermined distance.

2. A paint roller assembly as in claim 1 wherein the handle has an extension offset and parallel to the handle axis.
