BICYCLE.

SPECIFICATION forming part of Letters Patent No. 364,231, dated June 7, 1887.

Application filed September 28, 1885. Serial No. 178,484. (No model.)

' head, of the bicycle.

In the annexed drawings, making part of this specification, Figure 1 is a side elevation of the improved bicycle, and Fig. 2 is a front elevation. Figs. 3 to 10 are details upon an enlarged scale, Fig. 3 being a sectional View of a pedal, the section being on the line 5 5 of Fig. at; Fig. 4, a plan of a pedal; Fig. 5, an

outer end elevation of a pedal; Fig.6, a sectional elevation of the head; Fig. 7, a plan, partly broken away, of the head, and Fig. 8 a side elevation showing the mode of attaching a handle-bar to a fork already made. Fig. 9 isa detail showing thehandleextensible. Fig. 10 is a detail showing the handle extending backward, outward, and upward.

The same letters of reference denote the same parts.

A, Figs. 1 and 2, represents a bicycle of the customary construction, saving as modified by the present improvement. B B represent the handle-bars. They are attached ad j ustabl y or otherwise to the fork O, and respectively on opposite sides thereof, extending from a point about midway between the hub D and the head E, backward to about opposite the rear end of the saddle F, substantially as is represented at b in Fig. 1; thence laterally outward from the wheel sufficiently for the riders leg to pass between the wheel G and the upright portion of the handlebar, substantially as is represented at b, Fig. 2, and thence upward, as is represented at W, Figs. 1 and 2, and at the upper end being provided with the handle N, which preferably points horizontally forward, as shown in Fig. l. The handle-bars thus constructed may be made in one piece with the fork, as in Fig. 1, or they may be attached at any desired point to a fork, as in Fig. 8.

The handle-bar B can be so made as to be readily attached to almost any fork, and as is now generally indicated in Fig. 8, Where the end of the bar B is branched and secured. to the fork by aserew through its ends at any deployed.

.in Figs. 3, 4, and 5:

sired location; but in the merely mechanical details of carrying out this idea many differcnt methods of construction may be em- The upright part (see Fig. 9, not shown in Figs. 1 and 2) may be'made verti cally adjustable or extensible, to enable the handle Z) to be suited to the rider, who, when in the saddle, grasps the handles at each side of him and guides the bicycle as if the handles were attached to an ordinary handle-bar.

The advantage of this form of handlebars is that it enables the rider to mount from in rear of the large wheel in the usual manner, and to dismount either in the rear or in the front of the large wheel. It also permits of an upward pull upon the handle in propelling the wheel.

The construction of the pedal H, as shown The pedal-pin h is attached t0 the crank h by means of the nut if.

The inner end of the pedal-pin at h is threaded.

The outer end,h,is pointed. The pedal-frame Wis held in place and adapted to rotate on the pedal-pin by means of the nuts h and 71 the balls h and h". The pedal-frarne at h is inclosed, both to exclude dust and to retain the oil upon the bearing and prevent it from being rubbed against. The nuts h and h are beveled at their opposing ends, and after they are screwed on the threaded end of the pedal-pin into place their beveled ends jointly provide a bearing for the balls h The inner side of the pedal-frame bears upon the balls If. The outer side, at h bears upon the balls 71:", and by adjusting the nuts h and it upon the pedalpin, the balls h and the pedal-frame are drawn sidewise upon the pedal-pin, so as to hold the part h of the pedal-frame and the balls it" against the pointed end h, and the pedal is thereby held properly in place. All the parts of the pedal can be separated by removing the nuth from the pedal-pin, detaching the pedalpin from its crank, and then removing the nuts from the pedatpin.

The backbone I, Figs. 6 and 7, is attached to the fork G by means of the nut K. This nut is beveled at 70. The fork is beveled at c, and the backbone at it'svpoint of connection with the fork is shapedto form the concave ring 2. A series of balls, L, are inclosed between the ringt and the bevels k and c, and

the backbone can be tightened as desired upon the fork by screwing the nut upon the fork projection 0, Figs. 6 and 7.

The structure of the spokes, hub, and rim will not be claimed in this case, as they will form the subject of another application by me for patent thereon.

I am aware that heretofore the handlebar has been angled, but know of no case where it extends baekwardly, outwardly, and upwardly.

I clain1-- 1. In a bicycle substantially as shown, a handle-bar attached at one end to the fork about midway between the hub and head of the fork, and thence extending backward, outward, and upward, substantially as and for the purposes set forth.
