ANTI-FRICTION BUSHING.
SPECIFICATION forming part of Letters Patent No. 242,290, dated May 81, 1881.
' Application inea May 2,1881. (No moua.)
To all whom it may concern:
Be it known that I, THOMAS R. FERRALL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Anti-Frictional Bushings, of which the following is a. full, clear, and exact description. Y
This improved an ti-frictional bushing is composed in substance of a loose sleeve and a loose ring or rings surrounding the sleeve and constructed to receive or carry a series of loose friction-rolls, in combination with a box or casing, all substantially as hereinafter described, reference being had tothe accompanying plate of drawings, in which- Figure l is aface View ofone end of the box or casing. Fig. 2 is a construction on line 2 2, Fig. 1. Fig. 3 is a horizontal section on line 3 3, Fig. 2, Fig. 4, aside elevation of the loose sleeve detached; Fig. 5, a sectional view, showing modication in construction of loose sleeve; Fig. 6, a side elevation of theloose sleeve with the ring upon it; Figs. 7, 8, 9, and 10, views in modification to be hereinafter more partielllarly referred to.
In the drawings, A represents a cylindrical box or easing. This box, at one end, a, is open for its full diameter, and it is there provided with an external peripheral flange, b, and at its other end, c, it is closed only in part, and has its central portion, d, open. The open end a of the box is closed by a plate, B, which has a circular opening, f, through it corresponding to and concentric with the opening d at the other end of the box. This plate is fastened to the box by screws, and in order to have. it iiush with the open and ilanged end a of the box, such end is suitably recessed or shouldered, as at g, to receive it. (See Fig. 2 more particularly.)
C is a metallic ring, sleeve, or hub, having a shoulder, h, atl each end, and this hub or sleeve is conned by the shoulders of its two ends between the two ends a c of the box A, and exteriorly within said box it has, intermediate of its length, a peripheral groove, l, which receives a ring, D, which is free to move around upon it. This ring D has a series of notches or recesses, m, in its outer periphery, arranged at regular and equal distances apart, and each notch is of a similar circular shape, and each receives a friction-roll, E, all of a corresponding size and shape, and such as to bear against the inner periphery of the box and the outer periphery of the hub or sleeve O and to be coulned against escape at their ends by the two end pla-tes B o of the box. The notched or recessed plate separates the friction-rolls from each other and so holds them. The shouldered sleeve or hub, arranged, as described, between the two head or end plates of the box,
obviously cannot escape therefrom, and secures y a bearing upon an axle pin or shaft for the full thickness ofthe box or casing. The sleeve or hub is free to revolve in contact with the friction-rolls, the friction-rolls in contact with the sleeve or hub and box, and the recessed ring upon the sleeve or hub, all as is obvious without further description.
This im proved frictional bushing is intended for pulley-sheaves, carriage-hubs, and other analogous purposes, and in such cases its advantages are plainly apparent, and therefore need no particular recital herein.
The peripheral groove l of the hub may be secured in various ways-as, for instance, by grooving the hub, by making the hub transversely in two parts and making cach of such parts of such forni that when put together they will leave the desired groove, (see Fig. 2,) by shoulderin g the hub, and then by the application of a separate and distinct ring, n, leave the desired groove. (See Fig. 5.)
The recessed ring may be in several sections or parts in lieu of in one piece, as described; but it is preferable to have it in one piece, which of course necessitates that the hub or sleeve which receives it should be in parts,
substantially as shown and described. lf in separate sections or parts, obviously they may be disposed, as described, about the hub without necessarily separating or dividing it.
The grooved hub or sleeve O, in its action in combination with the recessed ring D, obviously simply holds such ring from moving along the length of the hub, leaving it free to turn upon the same, and, as is plain, the same results may be similarly secured by grooving the inner edge of the ring and tonguing or Hangin g the hub to lit such groove.
The shouldered hub or sleeve C, as before stated, receives a bearing ofthe frictional bushing equal to the full thickness of the box or casing, and this result is in no sense dependent upon nor does it have the least bearing or relation either to the action between the sleeve and recessed ring, or between the sleeve and the friction-rolls, and the reverse is also true, and although it obviously is preferable to use it, yet it is plain that the hub or sleeve could be arranged to be ooniined simply by its two ends without shoulders between the end plates of the box.
The recessed ring, as shown, has its recesses open at its edge 5 but these recesses may be closed for their whole periphery, so that they will completely surround the friction-rolls; but as this construction, if no means be taken to obviate it, would prevent the l'rictional rolls from having a bearing upon the inside of the box, it is not desirable, nor is it necessary in any respect so fur as atl'ecting i'or the better or worse the operation ofthe recessed ring D, to keep the friction-rolls separate. However, it' a recessed ring ofthe modied construction above described be used, by simply grooving the periphery of the box or casing to receive the outer peiiphery of the ring the frictionrolls can be given their desired bearing upon the box.
The loose frictiolrrolls E, as shown and described, are solid, and are confined at each end from escape by the head or end plates of the box; but in lieu thereof they may be grooved about their periphery, and with the recessed plate in such groove of each they are thus held from escape from either end of the box and the ring heldin its position. (See Figs. 7 and S.) The solid ring, however, is preferable, as it is simple and cheap, ellicient and practical.
In Figs. 9 and l() is shown another way ot'- connecting the friction-rolls to the loose ring; and it consists of pins o upon the ring or plate and holes p in the rollers to receive such pins, the rolls being each side ot' the plate. It the ring and rolls be so connected, obviously thel loose sleeve, as has been described. This is also true in substance when the rolls are grooved and the ring entering such grooves of the rolls, as has been before described.
As to Figs. 9 and 10, the sockets and pins of the rolls and ring may be reversedthat is, the pins be in the rolls and the sockets in the ring-with the same results and elfeets.
More or less in number of the rings may be combined in one and the same anti-frictional bushing-as, for instance, one at each end of the friction-rolls, with a bearing of the rolls in each.
In anti-frictional bushings, &c., as well known, the combination of a loose sleeve and a series of loose frictionrolls is not new, and therefore such is no part of this invention.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. In an anti-frictional bushing, thecolnbination of a loose sleeve, C, a loose ring or rings, I), and loose friction-rolls E, constructed and arranged together and in relation to eachother and as to a box or casing, A, substantially as and for the purpose described.
2. In an anti-frictional bushing, a loose shouldered sleeve, C, in combination with a box or casing, A, all substantially as described, for the purpose specified.
3. In an anti-frictional bushing, duc., a loose shouldered sleeve, C, a loose ring or rings, D, and loose friction-rolls E, constructed and arranged together and in relation to each other and as to a box or casing substantially as and for the purpose described.
4. In anti-frietional bushings, the combina-- tion of a loose sleeve, C, having a peripheral groove, Z, a loose ring or rings, D, having rccesses m and entering such sleeve-groove l, and loose frictioirrolls E, arranged in said recesses, with a box or casing, A, all substantially as and lor the purpose described.
In testimony whereofl I have hereunto set my hand in the presence of two subscribing witnesses.
