ROLLER FOR GRAVITY CARRIERS Filed Feb. 25, 1924 CHARLES A. ADAMS, OF ELLWOOD CITY,

PENNSYLVANIA, ASSIGNOR '10 MATHEWS GRAVITY. CARRIERCOMPANY, OF. ELLWOOD CITY, PENNSYLVANIA, A CORPORA- TION OF PENNSYLVANIA.
ROLLER r03 enavrrir CARRIERS.
Application fiied'rebmary 23, 19%. Serial No. 694,732.
This invention relates to improvements in rollers, or conveyor members, of gravity carriers and is an lmprovement particularly upon the rollers illustrated-and described in' 5 thepatents to Herman J. Buck, No..1,238,- 880, issued September 4, 1917, reissued J anuary 20, 1920, NO."14:,792, and No. 1,445,821, issued February 20, 1923.
The object of the present invention is to provide means to secure in position in each end of the roller,'.=-'the head in which the anti-friction cage'of'the roller is mounted.
The invention consists in'the construction and combinations -hereinafter described and 15 particularly pointed-out in the claims;'
In the accompanying drawing,.form1ng part of this specification, Fig." -l is" an elevation and partiali'section of a gravity carrier roller, embodyi'ii'g'z iny' invention, the side rails of" the earrier'being shown in section and the supportingshaft, or axle, in elevation. I f
Fig. 2 is a-detailfi 5 j In the drawing 2, 2 represent the side rails of the carrier in which the carrier shaft, or axle 4, is -mounted;' 7 represents a conveyor or carrier} roller, preferably made of light steel tubin and-openatj-e'afch end. Arranged on thewfs" aft ;4, and capableof. rotary and-longitudinal movement thereon, is a sleeve, 18, on whichis mounted a-ball carrier cage, 17,21'ireferably of substantially the-rsame construction that is shown in the Buck- Patent No: 1,445,821, hi'einbefore re- 5 ferred to. ,A head, 8, is arrangedfin each end of the roller'fZ. This headis preferably in the form of an annulus, having the circular webs 9 and 10 united by 'a trans-. ,verse" web, 11. The outer surface of the 40 web 9 is -provideld with a circumferential depression, or rece'ss,"16. This web is prefer.- abl coincident with the'inner surface of the rol e r 7, so tha said head fits snugly-in the rollerf'with the rige'ess IGj-arranged opposite;
the extreme'end if the roller, which is"deress'e'd 'into the circumferential recess 16.
he ball-cage 175,-when' the bearing is assembled, is slidably seated within the web 10, the flange of saidcage resting against the edge of the web. With this construction the head is reliably and permanently secured in position in the end of the roller so that it is impossible for it to become loosened therefrom. In.-tl 1e ordinary construction of roller carriers'greatdifficulty is experienced in maintaining-the heads-in the rollers, as these heads workdoose and move ahead on the shaft into-the interior of the roller. In my. constructioii'I form the circumferential recess 16 with an'outwardly flaring wall 20, against which the edge 21 of the metal, forming the roller 7, abuts when the parts are assembled, as shown in the drawing. This makes-it absolutelyimpossible for the head, under anyv circ'um-' stances, to work ahead on the shaft-and get farther into the roller. ;f I
I have shown in detail o'nly the construction at one end of the roller. Itjgwillbe understood, however, that 'thesaiii'el'construction is preferably used onjboth ends; of the roller. v I claim as m invention'i 1. The combination of a' tubulai'ffgravity carrierroller, an anti-friction cage'iarran'ged "in the end of the roller, a head generally U-shaped in cross-section between' s'aid cage and the end of the roller, and supporting said roller, the head comprisinginner and outer circular webs; connected byga transverse portion, said "head opeiiingioiit from the end of the roller; and withfitjs'outer .webbed portion bent"'i nwardlyf wardly forming an annular 're'c ly open in its outer arments-(115mm of which is less thanthe'diaineterloi'the roller elsewhere, the end ofiitheioller'jtitting over the inwardly bent-sur fa'c'e-of head and having the end"'edg of,. the metal; of the roller seated against the {wall oi-said recess.
2. The combination. with .a' tubulapgravity carrier roller, of-an anti-frictiongfcege arranged in the end of the, .,rol le r,l afhead betweensaid cage and rolleifaii supporting said roller, said heaii cliiiiin' annular o ter we the u s li .f i si ite'iids inwardlyfito'wards the age. and thence outwardly from th fcagegtb recess'in the outer surface of said the=-end of the roller extendin -.-inwar dly nd its inwardly tux-ne -end -'fitti ver-fthe outer surface of saidhead,with tiie eiitrine end of the roller seatedagainst-thewall of said recess.
