To all who-In it neat concern.-

Be it known that we, JOHN GALT and ARCH- IBALD P. RANKIN, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and usefullmprovements in Ad j ustableHandle-Bars and we hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in the steering apparatus of bicycles, tricycles, quadricycles, tandem bicycles, and like Vehicles; and the object of the invention is to provide a steering post with a handle-bar the shape and elevation of which can be altered by the rider without dismounting; and the invention consists, essentially, of making the handlebar in two equal sections, the inner end of each of which is fitted with an eye having an internal segmental gear extending partially across its face and fitting the steering-post with a horizontal pin, on which are mounted the said eyes, providing the pin with two obliquelyopposed slots, and fitting into the pin two engaging pinions,each adapted to work through its respective slot and mesh with the gear of the eye of its respective handle-bar section in order that the movement of one handlebar section will cause a simultaneous corresponding movement on the part of the other handle-bar section, the whole device being hereinafter more'fully set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View showing our improvements, partially in section. Fig. 2 is a plan view of the top of the steering-post, the horizontal pin, and the engaging pinions. Fig. 3 is a transverse sectional view showing the eye of one of the handle-bar sections,thc engaging pinions, the horizontal pin, and the top of the steeringpost. Fig. 4 is a similar view of the other handle-bar section. Fig. 5 is a perspective view, partially in section, of the horizontal pin. Fig. 6 is a perspective view of the eye of one of the handle-bar sections. Fig. 7 is a perspective view of the eye of the other handlebar section. Fig. 8 is. a perspective View of the horizontal pivot.

Like letters of reference refer to like parts throughout the specification and drawings.

Screwed, brazed, riveted, or otherwise fastened'to the top of the steering-post A is a horizontal pin 15. The pin B is hollow and is provided with two obliquely-opposed slots 0 0. Located within the pin B are two pinions D D, so arranged asto engage with each other. The teeth dof the pinion D project through the slot 0, while the teeth d of the pinion D project through the slot 0. The teeth (1 01 project through their respective slots sufficiently to engage the teeth in the eyes of their respective handle-bar sections.

The slot 0 and pinion D are located contiguous to the head E of the steering-post, while the slot C and pinion D are located contigu ous to the screw-threaded part of the pin B. The pinions D D overlap each other sufficiently to allow the teeth (Z cl to mesh, to enable one pinion to impart its motion to the other.

Mounted on the pin B contiguous to the head E of the steering-post is the eye F of a handlebar section G. Mounted on the sleeve B contiguous to the eye F is the eye F of the handle-bar section G. The adjacent side face of each of the eyes F F is provided with a series of serrations g g, respectively, which interlock and assist in holding the handie-bar sections in their adjusted positions.

The inner face of the eye F is provided with a semiannular gear H, the teeth of which extend partially across the inner face of the eye, and between the end of the teeth H and that side face of the eye F contiguous to the eye F is a clearance h, entirely devoid of teeth. The inner face of the eye F is provided with a semiannular gearH, the teeth of which extend partially across the inner.

face of the eye. Between the end of the teeth H and that side face of the eye F contiguous to the eye F is a clearance h. The

teeth of the semiannular gear H mesh with the pinion D, while the teeth of the semiannular gear H mesh with the teeth of the pinion D. The clearance 7L precludes any possibility of the teeth of the semiannular gear H meshing with the teeth of the pinion D, while the clearance it prevents any possibility of the teeth of the semiannular gear H meshing with the teeth of the pinion D. Screwed on the end of the pin B is a locking cap or nut I to hold the several parts together.

The operation of the device is as follows: By releasing the locking cap or nut I the handle-bar sections can be moved in either direction. Assume that the handle-bar section G is moved upward or in the direction indicated by arrows,the teeth of the semiannular gear H meshing with the teeth of pinion D, and the teeth of the pinion D meshing with the teeth of the pinion D, and the teeth of the pinion D meshing with the teeth of the semiannular gear H. The upward movement of the handle-bar section G causes a corresponding si- 1 multaneous movement on the part of the handle-bar section G. the handle-bar section G would cause a reverse movement of the handle-bar section G.

When the handle-bar sections have been adjusted to their properpositions,tl1e locking cap or nut I is screwed tightly against the adjacent 1 side face of the eye F of the handle-bar sec tion G and locks the two sections tightly against each other and against the head of the steering-post.

sections in their adjusted positions.

By means of this device the handlebar sections can be raised or lowered, as required,

in any position, and when stored in a hall way can be lowered to occupy a more limited space than they otherwise would.

what we claim as new, and desire to secure by Letters Patent, is-

their inner ends on coincident axes, an intermediate connecting-gearing sustained by the head and operatively connected to the handlebars and means for holding the handlebars in their adjusted positions.

2. The combination with the steering-head of the two handle-bars provided with gearteeth and pivotally connected to said head on coincident axes, gear-wheels mounted in bearings sustained by the head and meshing with each other and also with the teeth on the handle-bars, and means for locking the handle-bars in their adjusted positions.

3. The combination with the steering-head provided with a horizontal arm formed with bearings, of two intermeshing gears mounted in the bearings in said arm, two handle-bars provided at their inner ends with eyes to receive the arm and formed with internal gear- The reverse movement of It might be stated that by this arrangement of parts it is possible for the rider to adjust the handlebar sections without dismounting and to lock the handle-bar through which passes the horizontal arm, an
