`SPECIFICATION forming part of Letters Patent No. 282,539, dated Aiigust '7, 1883.

- Application filed January G, 1883. (Nomode.)

To @ZZ whom t may concern,.-

Bre it,known that l, PERIEs LINCOLN, a citizen of the United States, residing at Coldwater, in the county of Branchand State of Michigan, have invented certain new and useful Improvements in Axles, Axle-Boxes, and Bands, of which the following is a specification, referen ce being had to the accompanying drawings.

My invention relates to the peculiar construction of pipe-boxes, axle-trees, and wheels for Vehicles.

One object of my invention is to construct an axle of such a form that the hub will be held to its place without a nut on its outer end. Another object is to construct athilnble skein or box that can be retained in place on the axle without the use of a nut on the outer end of the axle. VAnother obj ect is to so arrange the spokes and axle-box that the spokes may be tightened by changing the .positionof the hub on the axle-box. Ll attain these objects by the peculiar formation and arrangement of the various parts of my invention, as will be more fully pointed out in the specification and claims. v t

Similar letters refer topsimilar p arts throughout the drawings..

In the drawings, Figure l represents a longitudinalsectional view of my invention, showing the axle, axle-box, hub, spokes, and section of tightening-band. Fig. 2 is a perspective View of the axle, showing the springs for retaining the axle-box in place. Fig. 3 is a plan view of the thimble-skein or axle-box.

A represents an axle-arm, formed in the usual manner, with a square shoulder ou its inner end, against which a washer or the hub works, as will be more fully described hereinafter,

Two springs or metal strips, c and c, are formed with their outer ends curved outward and extended on either side to form T-shaped projections, the ends of said projections being curved inward in the form of a half-circle, the inner ends of said metal plates being perforated to receive a bolt, b, that passes through a perforation in axle-arm A, and by means of which saidsprings are held in place. .Between the outer and inner ends of said metal plates pins c `and c' cross the axle, and underneath the springs said pins are secured in place by means of staples d d. The purpose of said springs is to press the outer ends of plates a c from the axle. y

B represents a pipe-box or thinible-skein, formed of metal, (preferably cast.) The outer end of said pipe-box is formed with ascrew- ,thread upon its outer surface. The inner end of said pipe-box is enlarged to form a shoulder,

e, and on the inside of the enlargement an annular recess, f, is formed, for the purpose of receiving the curved ends of the metal plates a and a. From the shoulder e outward the pipe-box is enlarged to a point, g, about onethirdpits length, and from point g to near the screw-threads it is formed tapering. The said pipe-box is splined in the usual form, for the purpose of holding the same in place in the hub. Screw-threads are formed on the inside of the outer end of said pipe-box, for the purpose of receiving the screw-threaded cap h, said cap being in the form of a disk with a central screw-threaded projection, and its purpose is to prevent grease from exuding from the end of the hub, and it also prevents garments from being soiled should they be brought in `contact with the end of the hub.

An ordinary nut or burr, z', is formed `with" angular sides for the reception of a wrench, by f which it is turned, and screw-threaded on its inner surface and adapted to fit and screw onto the outer end ofthe pipe-box B, the purpose of which is io force the hub onto the pipebox B. y Awashenj, is formed of sufficient diameter to pass loosely over the pipe-box B up to and against the shoulder e.

Al hub, C, is formed in the usual manner and ofthe proper form and size on its inner surface to receive the axle-box B. The ends of the said hub are banded with metal bands to prevent splitting"`o`r checking. HubB is mortised through from the outer to the inner surface ffor the reception of spokes.

Two metal bands, k and 7c', are formed to pass around the hub B on either side of the spokes and embrace the saine. Both bands are formed with an upwardly-projecting flange or lip, Z and l. The inner faceof lipsl and Z are formed with inwardly-inclined surfaces extending from the outer edge of said flanges down to the lower face of the bands kand k. Said lips or iianges are perforated toreceive IOO againstthe outer surface of pipe-box B. At the point of contact with the pipe-boX said spokes are cut slightly inclined to coliform to the inclination of the pipe-box B, the purpose of which is to force the spokes outward when the pipe-box is forced i'nto the hub far enough to bring the enlarged part of said pipe-box against the inner ends of the spokes.

The spokes used in my improved wheel are ,beveled or inclined outward at or near vtheir shoulders on the outer surface of the hub, for

i the purpose of fitting tightly against the i11- side of the lips or flanges Z and Z of the bands la and 7c. When the spokes become loose by shrinkage, the washer j is removed and the pipe-box B is forced into the hub against the ends of the spokes, thus forcing them out against the inclines of the bands 7c and 7c and said springs being pressed outward by fulcrum-rods c and c, each spring: formedfwith an upwardly-curved shoulder and inwardlycurved lips, as shown, on its outer end, said 35V shoulder and lips adapted to engage with the outer' shoulder of the annular recess f, formed in the inner end of pipe-box B, substantially as shown and specified.

2. rlhe combination of a wooden hub of a vehicle-wheel, its middle portion surrounded with bands 7c and k', having outwardly-projecting iianges with inwardlyinclined faces,

as shown, said hub being formed with straightfaced mortises extending through the shell of 4 5 the same, in which spokes are inserted, the pipe-box B having inclined outer surface,

its outer end inwardly and outwardly screwthreaded, as shown, with the screw-threaded nut z, adapted to screw on the outer end of 5o said pipe box, substantially as shown and specified.

3. ln combination, the axle A, pipe-box B, hub C, bands k and k', recess f, and nuts t' and h, all arranged and operated as shown, substantially as and for the purpose set forth.

In testimony whereof l affix my signature in presence of two witnesses.
