' Application filed October 27 1917. Serial No. 198,763..

To all whom it may concern:

Be it known that I, CHARLES S. LocKwooo, a citizen of the United States, residing at 496 Clinton avenue, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Roller-Bearings with Sectional Rolls, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to an improved construction for the rolls of a roller-bearing, by which rolls spirally grooved or wound in opposite directions may be employed to facilitate the distribution of oil in the hearing, and without any tendency of the rolls to crowd toward either end of the hearing so as to wear upon the heads of the hearing or the heads of a cage movable therein.

Such tendency is avoided by means which operate independently of the cage to hold the roll-sections from moving apart from one another.

To prevent the sections of the roll fi'om working apart from one another when carrying a heavy load, a tie-bar is inserted through the bore of the roll and collars secured upon the tie-bar in contact with shoulders upon the ends of the roll; thus preventing the sections from separating, but permitting them to turn freely independent of one another when required.

Such tie-bar is preferably formed with pintles at the ends, the tie-bar being shouldered down to form such pintles, and at the same time to form shoulders to which the collars may be secured. Such pintles are adapted to ilt loosely in holes in theheads of a roll-cage, and thus hold the rolls in arallelism during their movement in the caring.

The collars may be verycheaply secured to the tie-bars adjacent to the end shoulders, by grooving the pintles next the shoulders and after the collars are applied thereto pressing the metal of the collar inward against the pintle and forcing it into the groove, which looks the collar permanently thereon.

The invention will be understood by re erence to the annexed drawing, in which Figure 1 is an end-view of a roll-cage with one of the cage-heads removed; and the collar in the nearer end of one ofthe rolls omitted. Fig. 2 is a section of the roll-cage on line 22 in plied to the rolls. In Fig. 2 the ends of the rolls are recessed to receive the collars. Fig. 3 is a side-view of one of such rolls removed from the cage; Fig. 4 is an end-view of said roll; Fig. 5 is a perspective view of one section of said roll; Fig. 6 is a side-view of the tie-bar used in said roll; Fig. 7 'is a view of one end of the tie-bar enlarged with a collar locked thereon; Fig. 8 shows a section similar to that in the lower part of Fig. 2 with the collars bearing upon the extreme ends of the roll; Fig. 9 is-a side-view of such a roll, and Fig. 10 is an end-view of'such a roll.

a and a designate cage-heads of usual construction,-the heads a being omitted in Fig. 1. b designates cross-ties having their ends secured to the heads when the parts are all assembled. Each roll is shown divided transversely into sections 0 and 0', being formed of strands wound spirally in opposite directions with grooves or interspaces d between the coils. the end of the roll is shown with recess e forming anv annularv shoulder e far enough within the end of the roll to receive a collar f. A tie-bar the roll in the lower part of Fig. 2, its ends being shouldered down forming pintles h to fit rotatably in the holes 2' in the cage-head.

The shoulders upon the tie-bar are at such distance apart that when the collars f are secured upon the pintles the roll-sections c and 0' are held snugly together but rotatable independently of one -another.

A very effective way of securing the collars next the shoulders upon the tie-bars is shown in Figs. 2, 6, and where the neck of the pintle is shown withan annular groove j, and a collar is shown applied to the pintle in cont-act with the shoulder upon the tie-bar, and the metal of the collar pressed inwa dly around the pintle, as indicated by the depression liesuch pressure upon the metal crowding it into the annular groove 9', as shown in Fig. 7, and locking the collar firmly to the die-bar.

By forming the recesses e in the ends of the rolls, the collars can be sunken therein and the healing-surface of the roll thus enabled to extend from one of the heads to the other in the cage.

The tie-bar and collars-can operate in precisely a similar manner it the collars are Fig. l, with both heads t .In Figs. 2 to 5 inclusive, I

g is shown extended through end elf fine 011 es e the sneuiciere Y on the tie-ban g are enevvn coincident with i -he outer encis of fine 1 01i, and the sellers secured. against the seici shoulders by the means deserieeci in eenneetien with Z. With the same ee-ge, the reiis of this lam/e1 oonstmciien are necessarily silent/e1 with the design shown in Fig. :2.
