SPECIFICATION forming part of Letters Patent No. 541,238, dated J une 18, 1895.

Application filed March 26, 1395. Serial No, 543,197. (No model.)

To a/ZZ whom t may concern:

Be it known that I, HARLEY F. KENDALL, a citizen ot' the United States of America, residing at Springfield, in the county of Hampden and State ot' Massachusetts, have invented new and useful Improvements in Pedals for Bicycles, ot' which the following is a speciiication.

This invention for improvements in bicycle pedals more particularly pertains to improvements in the means of connection of the pedal-shaft with the crank, and in the means of connection ofthe foot-bearing blades of the pedal-frame with the arms which at their extremities support the blades; and the invention consists in the constructions and combinations of parts all substantially as will hereinafter fully appear and be set forth in the claims.

Reference is to be had to the accompanying drawings, in Which- Figure 1 is a side view of the pedal and a portion of the crank to which it is attached. Fig. 2 is a plan View, the detachable rubbers and the conning devices therefor being indicated by a dotted line. Fig. 3 is a central horizontal sectional view taken on line 3 3, Fig. 1, 011e of the detachable rubbers and the confining means therefor being here positively shown. Fig. 4 is an elevation and sectional view as taken on the line 4 4t, Fig. 3. Fig. 5 is a perspective view showing the pedalshaft and various other parts to be hereinafter more particularly referred to. Fig. 6 is an illustration of the inner and outer faces of the end of the crank. Fig. 7 is a perspective view of the sleeve or tubular v.center ot the pedal-frame. Fig. 8 is a perspective view of one ot' the fastenings for the rubber. Figs. 9 and 10 are sections in detail transversely through the end of the crank on the lines 9 9 and l0 10, Fig. 6.

In the drawings, A represents the pedalshaft, B represents the pedal-frame and C represents the crank. The crank has the cruciform opening, D, two of the wings, 11, 11, of which extend straight through the crank from face to face, while the two wings, 12, 12, which are at right angles to those, 11, 11, extend only partially through the thickness of the crank, their bases constituting solid seats, 13, 13.

These bases are preferably inwardly beveled. The pedal-shaft has its end of attachment formed with the radial lugs, ci, a., the width of which corresponds to that of the said severalV wings, 11, 12, of the opening, D. The pedal-shaftis, inside of its lug-provided end, screw-threaded and receives thereon the nur, b. By screwing the said nut inwardly, sufficiently, the pedal-shaft may be slipped 6o removed from the crank (as it may be by inwardly turning the nut on the pedal-shaft sufticiently far) the nut is not detached, and there is no liability of its becoming lost.

The pedal-frame embodies the opposite foot-bearing blades, d, d, and the transverse arms,f,f, to the ends of which the said arms are connected and which Vare intermediately constructed with the ball-cases as usual, and this frame also preferablycomprises the tube, g, on the reduced ends of which the parts,f, f, are closely tted. The foot-bearing blades, d, d, have the lips, h,'h,vstruck up from portions ot the blades within their edges, these lips standing inwardly at right angles to the length of the blade. The extremities ot the arms,f,f, overlap these ears and are held by the screwsnl. Bolts with nuts might be used, but the screws as shown are deemed preferable.

In order to impart additional stiffness to the connection between the blades, d, and arms,f, the ends ot' the arms are formed with the separatedtenons, 20, 20, (see Figs. 1 and 5,) which loosely enter the mortises, 22, therefor in the blades.` The aforesaid set screws, in, constitute the entire connections tor the said parts, cl and f, the nccessityot' upsetting or riveting the endsof the tenons being obviated. Therefore, when it becomes desirable to remove a blade, in the event of breakage,

ICO

distortion, damage, and for the purpose of repairing `the pedal or sharpening the points, it is only necessary to remove the screws, i.

, It will be perceived from the illustrations that a combn ation pedal is provided whereby, at pleasure, the rider may have a rat-trap or a rubber pedal.

The rubbers, G, consist of fiat bars having a width greater than that of the blades or in any event sufficient to extend beyond the edge or edges of the blades, and the rubbers are held firmly to the blades, at the outer side thereof, by the metallic clampstrips,j. The rubbers and clamping strips are connected by means of the bolts, m, having the lateral extending lugs, m2, 'm2, one or more, the nuts, m3, and the provision of the openings, n, through the pedal-blades which are practically identical so far as their form is concerned with those-hereinbefore particularly described as being provided in and through the attaching ends of the crank. The nuts are applied at the outer ends of the bolts. By unscrewing the nut sufticiently far,-not necessarily removing them from the bolts,- the bolts may be pushed endwise inward so that the lugs, m2, clear the non-penetrating socket-wings in which they had been seated, permitting the bolts to be given a quarter turn, whereupon the bolts, rubbers, and clamping strips may bevall bodily removed from the pedal and without disconnection of the last enumerated parts.

In this pedal, I have provided at the inner bearing (as well as the outer bearing) a cone, t, which is formed separately from the pedalshaft and is adjustable longitudinally thereon by reason of its screw-engagement with the threaded portion, fr, at the extremity of the shaft, which is adjacent the crank. The same screw-threads may be continued, from the place Where the nut, b, is set up, to Within the bearings. This cone has outside'ot' the ballrace the outfiying tlange, t2. The ball-raees Aare surrounded and in part constituted by, the

endwise projecting hub, u, which is brought integrally With the pedal-trame and this is externally screw-threaded and receives the dust-cap, fu, which has its outer end wall o1* head centrally and circularly apertured to surround with closeness, and yet without obstructing the free rotation of the pedal, the

inner boundary of the ball-race which is of` less width than the diameter of the balls. When the pedal-frame is removed from the shaft, the balls are retained against dropping out of the race bythe washer. The washer may be removed by the use of a knife or otherwise. y

Having thus described my invention, what I claim, and desire to secure by Letters Pat:l

ent, is-

1. In a crank and pedal for bicycles, the combination with the pedal-shaft having at its end one or more laterally extending lugs and screw-threaded within such end of the crank having the transverse opening with the penetrating and non-penetrating wings, and the nut screwing on the shaft and against the inner face of the crank, substantially as and for the purpose set forth.

2. In a pedal, the combination with thef'oot-V bearing blades, d, each having the inwardly extending ears, h, h, struck up from internal portions of the blade and also having the adjacent mortises, 22, ot' the supporting arms,f,

f, having the tenons at their ends entering said mortises, the extremities of the'said arms overlapping said ears, and the'set-sci'ews, 1', fi, confining the ears and arms, substantially as described. A
