ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 560,521, dated May 19, 1896.

Application filed July 16, 1895. Serial N0. 556,203. (No model.)

To @Zt whom. it may concern:

Be it known that I, FRANK MOSSBERG, of Attleborough, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Roller-Bearings; and I do hereby declare that Athe following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in that class of antifriction-bearings known as roller-beari-n gs.

The object of this invention is to produce a bearing in which the journaled portion of the shaft will be provided with antifrictionbearing surfaces extending nearly the full length of said journaled portion.

The further object of this invention is to produce a roller-bearing in which the torsional strain exerted on the antifrictional rolls and the cage containing,` these rolls by the revolution of the shaft journaled therein will be reduced to a minimum.

In the drawings, Figure 1 represents a horizontal sectional view of the improved rollerbearing and journal, a part of a shaft being shown in elevation as journaled therein. Fig. 2 is a section of the cage lengthwise through its center after being bored for the rolls. Fig. 3 shows the ring of wire separate. Fig. 4. is a right-hand end view of the cage, showing the way of holding the rolls in the cage. Fig. 5 shows the flange made on the inside of the cage instead of the outside. Fig. 6 is one of the rolls.

In carrying out my invention I take a sleeve or tube A, made of suitable metal and of the proper diameter, the sides of the same being of considerable thickness, and starting at one end I bore it from end to end of a uniform size a little larger in diameter than the journal it is to be used upon. The outer surface of the sleeve is then turned off until the sides are of a less thickness than the diameter of the roll to be held in it, except that at the end fromvwhich the holes u were bored a stren gth-V ening-ange r isv left, which extends around the sleeve. A series of holes 'u of the proper size for the rolls CL to turn in easily are thenv drilled in the sleeve nearly to the bottom, leaving only a short portion 'n to hold the bars together at that end, as the drill cuts through on both the inside and outside of the sleeve except at the end where the flange o is, which flange holds the barsy together at that end. The rolls a a, Fig. 6, are then prepared from round bars of metal of a size to easily fit and rotate within the bearings formed by the concaved surfaces of the bars h, the ends of these rolls being rounded or slightly cone-shaped to avoid friction with the ends of the cage. The bearing holes or slots c in the cage being filled with a like number of rolls, a groove s is then made in the end of the bars inside the flange and a wire ring g sprung in, as shown in Fig. 3, to keep the rolls in when handled. The bearing is now complete and can be shipped without danger of the rolls falling out. When it is to be placed in position in a journal-box, I cut away a portion of the inner surface of said box at the end to admit the entrance therein of the fiange lr. lVhen in operation, t-hose portions of the rolls extending beyond the outer surface of the cage will bear against the inner surface of the journal-box,'while the portions of the rolls extending beyond the inner surface of said cage will bear against the journaled portion of the shaft, the end of which is generally surrounded with the collar H, secured in place on the shaft by the set-screw s.

It will be readily seen that the twisting or torsional strain either on the cage or on the rolls is entirely prevented by this device, the cage being free to revolve and the rolls to rotate in their bearings, in which they are held perfectly parallel to each other and to the line of the shaft, it being impossible for one end of a roll to move faster than the other end, which is usual in roller-bearings.

The fiange can be made on the inside, as in Fig. 5, in cases where it is better to make the rabbet for it in the axle or shaft instead of the hub of the Wheel or box.

Having thus described my improvement, I claim as my invention and desire to secure by Letters Patent- A cage for a roller-bearing consisting of a series of bars made integral or fast at one end with a collar, to hold the rolls, said bers having L groove made in the faces of the ends of the bers Where the spaces are left open for the insertion of the rolls, @Wire ring iitted to spring into said groove and hold the rolls in, 1o with rolls to occupy the spaces between said bars, substantially as described.
