retreat CONVEYER ROLL Application filed. April 5, 1930.` Serial No.` V211,752

This invention relatesto conveyer rolls of the anti-friction type, and has for an object to provide an improved roll that is simple in design, composed of Vrelatively few parts, and which is substantial, durable and eiiicient in operation. Another object is to produce an improved conveyer roll which is comparatively inexpensive to manufacture. A further object is to provide an improved anti-friction7 journal bearing for conveyer rolls with a simple, compact and novel arrangement for supplying lubricant to the bearings. It consists in certain features and elements of construction, in combination, as herein sho-wn and described and' as indicated by the claims.

In the drawing:

Figure 1 is a fragmentary verticalY section through a conveyer roll and its mounting, embodying my invention.

Figure 2 is a fragmentary perspective view of the conveyer roll and mounting.

Referring now in detail to the drawing: The conveyer roll, as illustrated, includes a f tubular body, 10, journaled on a shaft, 11,

whose Aends are carried in supporting brackets, 12. Firmly secured in each end of the tubular body is a head, 13, which may be in the nature of a stamping or a casting. Adjacent each end of the tubular body there are provided a plurality of depressed portions,

15, which in eect form an Vinternal abuts. It may be understood that these dedistance from the end of the tubular body so that the heads may be formed with annular flanges, 17, of substantial width, which flanges are dimensioned for a snug fit inside the end of the tubular body and serve to reinforce the same. The heads are lirmly locked in the ends of the tubular body against theV stop shoulders, 16, by spinning the extreme end portions of the tubular body over the outer peripheral edges of the head; as indicated at 18.

Each head, 13, as shown in Figure 1 of the drawing, is dished in cross section to form a cavity, 19, with an internal transverse stop shoulder, 20, and has its central area further ings, 27 This sleeve,

' which will greatly reduce the amount of luc. 2go
