HUB.

SPECIFICATION forming part of Letters Patent No. 513,258, dated January 23,1894.

Application filed August 23, 1893.

To all whom it may concern;

Be it known that I, CHARLES G. BERGER, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Hubs for Velocipedes or other Vehicles; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, and represent, in-- Figure 1, a side elevation of the hub; Fig. 2,

assembled thereon, and the ends of the fingers or lugs ready to be upset or bent upon them; Fig. 3, a cross-section of one of the annular plates, and an elevation of one end of the tubular member, showing how they are secured against relative rotary movement; Fig. 4, a detail view, being 'a section through one of the fingers or lugs, and showing how the spokes are drawn thereupon; Fig. 5, a detail View showing one of the fingers or lugs upset or bent down over a spoke-section.

- My invention relates to a hub for velocipedes or other vehicles, and the method of attaching the spokes thereto, and its object is to provide a convenient, strong and simple means for attaching the spokes to a hub and, whereto the spokes are held positively and firmly.

To these ends my invention consists in a hub, comprising a tubular member to receive the axle, annular plates or flanges at each end of the tubular member,.and a series of fingers or lugs projecting laterally from the sides of the rims or peripheries of the plates and having a substantial wedge-form in longitudinal section, produced by beveling or inclining the inner faces of the same, whereby to gradually tighten the spokes, which are formed in pairs from U-shaped sections of wire, the heads of the sections are forced along the inclined faces, and when they reach the bases of the fingers or lugs, the sections are secured in position upon the hub.

My invention also consists in certain features of construction and combination of $erial No. 484,207. (No model.)

parts to be hereinafter described and then particularly claimed. The tubular member a of the hub has an annular shoulder 1) near each end, and each entering end 0 receives the collar (1 of an annular plate or flange e, which fits jamb up against the said shoulder. Extending longitudinally outward from each shoulder 17 along the entering end 0 is a radial tapering fin or rib f, see Fig. 3, which enters a corresponding notch or recess g in the interior of the collar 61, whereby the latter and the flange thereof are interlocked with the tubular member a.

Projecting sidewise from each annular plate or flange e and outwardly from the rim or periphery thereof is a concentric series of equally spaced fingers or lugs 72. of malleable metal, whose outer facestl conform to the 0011- tour of and arefiush with'the said periphery and whose basesj are curved or rounded on In assembling the spokes with the hub, each spoke-section is slipped over a finger or lug h, its head a being in contact with the inclined inner face Z thereof. The heads a are then pressed inwardly over the inclines until they come in contact with the inner side of the annular plate or flange e, see Fig. 4,

whereby the spokes are drawn inwardly, and thereby strained and tightened. The free outer ends of the fingers or lugs are now upset or bent over and around the heads n of the spoke sections, as shown in Fig. 5, so as to tightly and firmly grasp them and retain them in position, thereby effectually looking or fastening the spokes to the hub.

I am aware that it is not new to construct the flanges of a hub to adapt them to receive U-shaped spoke sections and to be bent to impose strain upon thesaid sections, and also that The spokes employed 75 it is old to construct hub-flanges with radial fingers adapted to have U-shaped spoke-sections connected with them and to be bent and turned upon themselves inwardly to retain the sections in place and impose strain upon them, and I do not therefore claim either of those constructions broadly, but only my particular construction of laterally projecting fingers or lugs having inclined lower faces.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a hub, the combination with U shaped spoke-sections, of the hub proper comprising a tubular member, annular plates or flanges thereon, and a series of fingers or lugs projecting laterally from the sides of the rims or peripheries of the plates or flanges, and having a substantial wedge-shape in longitudinal section, produced by beveling or inclining the inner faces of the same, whereby the said U- shaped sections which form the spokes may be strained and tightened as they are forced over the inclined faces, the said sections being secured against the inner sides of the plates or, flanges substantially as set forth.

2. In a hub, the combination with U -shaped spoke-sections, of the hub proper comprising a tubular member, annular plates or flanges thereon, and a series of malleable fingers or lugs projecting outwardly from the outer sides of the rims or peripheries of the plates or flanges and having inclined inner faces, whereon the said U-shaped sections may be forced and strained, the ends of the fingers or lugs being upset or bent over the said sections, substantially as and for the purpose set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CHARLES G. BERGER.
