ANTIFRICTION- BEARING.

SPECIFICATION forming part of Letters Patent'iilo. 725,620, dated April 14, 1903. Application filed November 13,1902. Serial No. 131,169. (No model.)

This invention relates to improvements in IQ antifrlction-bearings; and the main object of my invention is the provision of a bearing whose bearing-rollers have their greatest-di-i ametered portions contacted by the revolving bearing-surfaces and having their smaller I portion contacted by the stationary bearing surfaces, or vice versa, and also means carried by'the bearing-rollers for holding them properly spaced.

Another ob ect of. my invention is to mount by the rollers and that the revolving motion of the cage may be slower'in proportion to the revolution of the revolving bearing-sur- 2 5 face of the bearing.

To attain these objects, the invention consists of a roller-bearing embodying novel fea-.

tures of construction and combination ofv ders 9 of the bearing-rollers, while in Fig. 2 'I place thrust-rings 16 upon both ends of the parts, substantially as described herein.

In the accompanying drawings, Figure l is a sectional view of my bearing as applied toa journal and boxing, the journal being the revolving part. Fig. 2 is a similar view, except that the boxing is the revolving part of the bearing. Fig. 3 is a similar view applied to a bicycle crank-hanger. Fig. 4 is a seciional view of the bearing as applied to a bi: cycle hub and axle. Fig. 5 is an end view of one of the entire cages. 12, and 13 are detail views of modified forms of tie-rods used in combination with the cage and also bearing-rollers and retaining-rings. Referring to the drawings, the numeral 1 in Figs. 1 and 2 designates the journal, having mounted thereon the sleeve 2, which allows all of the bearing elements to be removed from the journal. Centrally located of the sleeve is the enlarged portion 3, which in'Fig. 1 contacts the enlarged portion 4 of the bearing-rollers and their cage so that the end thrust of the bearing may be taken up- Figs. 6, 7, 8, 9, 10,11,

' the bearing-rollers, but which in Fig. 2 forms only an abutting means for the two rings 5'. These rings 5 in Fig. 2 form bearing-surfaces for the reduced ends 6 of the bearing-rollers, while in Fig. 1 they form abutting rings 5 for the flanged-end nuts ,7 and also means for retaining the thrust-rings S. I reduce and shoulderthe inner ends of the rings 5 and 5 and mount thereon the rotatable thrust-rings 8 and 8 for the enlarged portion 4 and the shoulders 9 .and 9 of the bearing-rollers, as shown in Figs. 1 and 2, respectively.

7 In the boxing 10 and 10 I employ the central lining sleeve or ring 11 and 11,which is ;integral. In Fig. 2 the sleeve 11 contacts the portion 4 of the bearing-rollers and, as shown in Fig. 1, forms a spacing and holding means for the two rings 12, which are opposed to the rings 5 andsubstantially the same length. In Fig. 1 these rings 12 contact the reduced portions 6 of the bearing-rollers,while in Fig. 2 the rings 12 form spaces for the flanged nuts 13, which are flanged oppositely to the nuts 7, so as to, in conjunction with saidnuts, provide recesses for the reception of the retaining-rings 14 of the bearing-rollers. In Fig. 1 I provide thrust-rings 15 upon the inner ends of the rings 12 for the shoulbearing-linings llfor the ends of the portion 4 of the bearing-rollers. V

In Fig.3 the numeral 3 designates a modification of the enlarged portion 3, as shown,

in Figs. 1 and 2.

In Figs. 3 and 4 I mount two sets of bearing-rollers 4 in practically the same manner as in Figs. 1 and 2, respectively, except that I dispense with the sleeve 2, which I would state at this time can be'dispensed with in all figures mounting the various parts upon the journal 1, axle 1, and crank hanger shaft 1".

In Fig. 3 I have dispensed with the thrustrings 15, as these rollers are so small as not to necessitate the thrust-rings at this point. The linings 11 in this form are formed integral with the boxing, having mounted thereon the rings 12 and 12 and having the central inwardly-projecting shouldered portion 17 to properly space said rings 12 and 12 and thus prevent inward movement of both sets of bearing-rollers.

In Fig. 4 I dispense with the thrust-rings 8, but provide a central annular shoulder 3 and oppositely-extending portions 3*, terminating in the shoulder 18. The rings 19 surround the portion 3 and abut against the shoulder 3*, which prevents the inward movement of the bearing-rollers, while the shoulder 18 forms an abutting means for the rings 5.

I employ the thrust- rings 18 and 18", the former of which fits in a recess formed at the inner end of the rings 12", the bearing-sleeve 18 forming the inner abutment for said rings 18, while in the inner ends of the bearingsleeve 18 I provide a recess to receive the thrust-rings 18", the shouldered ends of the portion 17 forming the inner abutment to limit the movement of said thrust-rings 18".

As shown in Figs. 1 and 3, the tie-rods 19 for the cage pass through the bore 20, which is formed in each alternate roller. Shoulders 21 are formed on the tie-rods, and conical washers 22 abut against the face of this shoulder and the inside of the rings and provide means for adjusting the bearing-rings 14 relatively to the bearing-rollers and at the same time provide aconical bearing for roll-.

instead of conical-that is, the shoulders 21 are formed on the tie-rodsand the washer or journal 24 fitsin the cylindrical recess 23 of the bearing-roller.

In Figs. 1 and 5 I employ the antifriction spacingv device 25, which is more clearly shown in Fig. 6. This spacing device consists of the supports 26, provided with the head 27, the journal 28 for the roller 29, and the reduced portion upon which is mounted the washer 30, which abuts against the shoulder of the journal and the face of the ring and in conjunction with the head forms abutting shoulders for the roller. The reduced end is threaded and is adapted to pass through or be secured within the opening 31 in the I rings 14 and may be more securely held thereopenings 37 for the reception of the rollers 38. In the openings 37 I adjustably mount the threaded pin 39, which has a depression in its inner face to engage one pintle of the roller and retain the other pintle in the depression 36, so as to adjustably mount the roller in the frame. In Fig. 8 I cut away the frame 34 upon its lower edge, so as to form a notch 40 for the reception of the roller, which is adjustably journaled in the frame in the same manner as in Fig. 7. These frames fit in radial grooves 40 in the inner face of the rings to prevent the frame from twisting. The bearing-rollers not mounted on the tierods and all the rollers, as shown in Fi 4, are provided with pintles 41, which are journaled in conical recesses 42 upon the inner faces of the retaining-rings.

In Fig. 4 I employ the tie-rod, as shown in detail in Figs. 9 and 10. This tie-rod in plan View is substantiallyrectangular, being provided with the central cut-away portion 43, so as to properly space the enlarged portion of the bearing-rollers. Upon opposite sides of the portion 43 I provide apertures 44, having upon their inner edges conical bearings 45 and upon opposite sides thereof and extending through the tie-rod to its ends the threaded openings 46 for the reception of the threaded adjustable pins 47,which adj ustably hold the spacing-rollers 48 in place. These journals also extend through the retainingrings and by means of the nuts 49 hold the retaining-rings relatively to the bearing-rollers. The shoulders 9 of the bearing-rollers instead of being formed integral with the bearing-rollers may be rotatably mounted thereon, thus dispensing with mounting the thrust-rings upon the rings 5, as shown in Fig. 2, and the rings 12, as shown in Fig. 1.

From the foregoing description, taken in connection with the drawings, it is evident that I provide an improvement in roller-bearings in which the bearing elements are so arranged as to greatly reduce the friction in all points of contact, this reduction being obtained by means of novel means.
