SPECIFICATION forming part of Letters Patent No. 742,512, dated December 22, 1903.
- Application filed April 16, 1903. Serial No. 152,683. (No model.)
To all whom it may concern: their inner edge with recesses 9, and in these 50 Be it known that I, GEORGE N. TOMS, a citirecesses 9 the roller-shafts 6 engage and are zen of the United States, and a resident of held in proper relative position. Between Boston, in the county of Suifolk and State of the rings that form the inner'casing 4 are in- 5 Massachusetts, have invented a new anduseterposed split thrust-rings 10, which prevent ful Improvement in Antifriction Devices, of. lengthwise movement of the roller shafts 55 which the following is a specification, refer- 6. These split thrust-rings are shown in eleence being had to the accompanying drawation in Fig. 2. The ratio of the diameter ings. of the roller-shaft 6 to the diameter of the 10 My invention relates to improvements in enlargement 3, upon whichit rides, is equal roller-bearings, and particularly to that class to the ratio of the diameter of the collar 7 to do in which proportional circles of rotation are the inner wall of the inner casing 4, upon used. 7 which said collars 7 ride.
The object of my invention is to provide The outer casing 11 projects at both ends '15 an antifriction device which shall be simple beyond the wooden hub 12 audits projecting and cheap in construction, easily assembled, ends are formed with screw-threads, and are 65 and eflicient in operation. thereby adapted to engage the caps 13 and In the drawings I have shown my device as 14, as is shown in Fig. 1. These caps 13 and applied to an ordinary wheel and axle; but 14 are formed with annular recesses 15, with- I desire it to be distinctly understood that I in which the wooden hub 12 is fitted, and they do not confine myself to that embodiment of therefore serve not only as dust-caps, but 70 my invention, for my invention may be apalso as retaining devices for the hub 12 and the plied to many other uses than the one herein parts of the rollerebearing. Awasherof felt or specifically shown and described. like materiallti serves to aid in the exclusion In the drawings, Figure 1 is a sectional of dust and moisture on the inside of the View on the line A A, Fig. 2.

1 is a standard axle upon which is a sleeve The spokes 18 are fitted between the flanged 2, having formed on its outer cylindrical snrbands 19 and secured in the usual manner face a plurality of enlargements 3, and 4 is by the rivets 20. the inner casing, made up, of three rings, as I believe that the new roller-bearing herein is clearly shown in Fig. 1. 7 described and shown is the only roller-bear- 85 Between the sleeve 2 and the rings that ing having the following characteristics and form the inner casing4 are interposed a plu-" at the same time applicable to an axle havrality of roller shafts 6, each of which is inga tapering'end: The sleeve 2 extends the 40 formed with a plurality of collars 7. At the length of the axle end and is formed with a ends of each shaft 6 the collar is split or reconical bore which makes it adaptable to a 90 cessed, as shown in Fig. 4, to receive a thin, taper-end axle, and the roller-shafts o extend flat, or disk-like separator-ring 8, which is the length of the sleeve 2, the collars 7 riding illustrated in perspective in Fig. 5 and in upon the rings-of the inner casing 4, while elevation in Fig. 3. The separator-rings 8 the rollershafts ride upon the enlargements are made in two parts or split, as is shown in 3 of the sleeve 2. The thin recessed split 9 Fig. 3. This construction permits of the separator-rings 8 space the roller-shafts cirready assembling of the roller-shafts in posicumferentially around the sleeve 2 and serve tion. The separatorrings are formed on as bearings for the said shafts 6. The spaces between the collars 7being too long to admit of the use of a thin separator-ring 8 I groove circumferentially the end collars to receive said thin rings 8. The nut 17 retains the sleeve 2 and the roller-shafts 6, aided by the split thrust-rings 10, against lengthwise displacement, while the caps 13 and 14 hold the several parts of the structure together in assembled relation as well as exclude dust.
What I claim is 1. An antifriction device made up of the following instrumentalities: ashaft; asleeve upon said shaft, said sleeve being formed with a plurality of enlargements; a plurality of roller-shafts formed with a plurality of collars, which collars ride upon an inner casing while the portions of said roller-shafts between said collars ride upon said enlargements; a pair of thin two-part separatorrings formed with recesses within which said roller-shafts engage; said inner casing made up of a plurality of rings; a plurality of twopart thrust-rings which are interposed between the rings of said innercasingand which project inwardly each between a pair of the collars on each of said roller-shafts; and an outer casing.
2. The combination with an axle; a wheelhub; an outer casing projecting beyond said hub at each end; and an antifriction device interposed between said axle and easing; of caps each formed with an annular recess adapted to inclose the end of said hub and a second annular recess formed with screwthreads to interlock with the projecting end of said casing.
3. The combination of an axle; a sleeve formed with a plurality of enlargements and extending the length of the end portion of said axle; a plurality of roller-shafts which extend the length of said sleeve and are formed with collars which engage between said enlargements; thin two-part spacingrings which are formed with recesses within which said roller-shafts engage and which are fitted into narrow peripheral grooves in said collars; thrust-rings which project inwardly between said collars; an inner casing upon which said collars ride; an outer casing; and a cap adapted to engage said outer casing.
4. The combination of a hub; an axle; an outer casing; an antifriction device mounted upon said axle; aflanged retaining-nut which holds said device upon said axle; and caps each formed with a plurality of recesses, one of which incloses the end of said hub, 21. second of which is screw-threaded to engage the projecting end of said casing, and the other of which receives said nut; said casing projecting beyond said hub at each end.
5. The combination of an axle having a tapering end; a sleeve fitting on and extending the length of said end, and formed with a series of circumferential grooves; rollers portions of which enter said grooves; an inner casing which coacts with said rollers; an outer casing; a wheel-hub; and a pair of caps adapted to lock said outer casing and wheelhub together.
6. In a roller-bearing, the combination of an axle having a tapering axle end; a sleeve formed with a series of circumferential grooves and adapted to fit on said axle end; a plurality of roller-shafts formed with a plurality of collars; said collars engaging in said grooves; two-part separator-rings for spacing said shafts; a casing made up of a plurality of rings; thrust-rings interposed between the rings ofsaid casing; an outer casing; a wheelhub surrounding said outer casing; and a pair of caps adapted to lock said hub, outer casing and casing-rings in their relative positions.
In testimony whereof I have hereunto set my hand at said Boston, in the presence of two witnesses, this 8th day of April, A. D. 1903.
