TRICYCLE.

srncrmonrron forming.

To ctZZ whom it may concern.-

Be it known that I, HENRY K. SHANCK, of

Dayton, in the county of Montgomery and' improvement consists of the novel constructicn hereinafter described and claimed.

In the drawings, Figure 1 is a vertical section of my improved tricycle. Fig. 2 is a rear elevation of the same, and Figs. 3, 4, 5, and 6 are detail views.

The framework of my improved tricycle consists of apendent frame, A, mounted upon the axle B, and extended to the front and rear downward near the ground, and connected to the yoke C of the guiderwheel D by a gooseneck E. The inclination of the goose-neck is to be such as to throw the handles F of the yoke within easy reach of the rider, who is to occupy a seat, G, arranged justabove the axle on the frame A. At or near the rear extremity of the pendentframe A is a transverse stationary shaft, H, having a pair of pulleys, I I, loosely mounted thereon, and connected thereto by clock-springs J, arranged within the pulleys. To the pulleys I are connected cords K, which are adapted to be wound thereon by the action of the springs, and these cords are attached to the pulleys L L, respectively. To the pulleys L L are also attached cords M, M, which extend down in front of the axle, and are connected to the pedal-levers N N at points intermediate between the ends of the pedals. The pedals are to be loosely connected in any suitable manner to the shaft H. The pulleys L, which are mounted upon the axle B, are preferably to be made with spokes, and provided with two or more peripheral grooves,

" O O, of different diameters, and the cords M M are to be secured in perforations formed in the smaller grooves, and adapted to be laid over from the smaller to the larger grooves through recesses I, as shown in Fig. 4, when it is desired to increase the driving-power, as in heavy roads. The cords K are secured in the larger grooves O in like manner, and these part of Letters Patent No. 289,151, dated November 2'7, 1883. Application filed January 26, 1883. (No model.)

larger grooves are to be made wider than the smaller ones, in order to provide suiiicient room for winding the two sets of cords thereon, when the cords M are placed in the larger grooves for the purpose above described. The pulleys L are to be provided with ratchets and pawls in the usual manner, and it is designed, also, that the wheels Q. shall be provid ed with ratchets, to facilitate the turning of the vehicle around sharp curves.

It will be observed that instead of placing the clock-springs on the axle of the vehicle, in the usual manner, I locate them at the rear or pivoted end of the pedal-levers. The object of this construction is to adapt the machine to utilize the pressure or weight upon the pedals for exerting both an upward draft and pressure upon the rear of the frame A, so that the entire burden or weight of the rider on the vehicle shall be practically thrown forward, without special effort, to a position for acting upon the propelling apparatus, instead of resting squarely upon the axle. In this manner less muscular force is required for propelling the vehicle, since the weight of the rider is utilized in great measure for that purpose.

Instead of the two sets of cords, one set of continuous cords passing over the pulleys L and connecting the pedals with the pulleys I might be used, although I prefer the arrangement first described. If desired, also, additional clock-springs might be arranged in the pulleys on the axle.

On the yoke O are arranged springs R R, to break the jarring caused by the guide-wheel striking obstacles or uneven surfaces in the road. It is designed that a spring-cushion shall be used for the seat to assist in securing the same object. 7

S indicates the brake for the guide-wheel.

As shown in Fig. 6, the cords M are to be made of extra length and wrapped around the cross-bars T of the pedal-levers before being secured thereto, in order that they may be adjusted in length as occasion may require.

By constructing the tricycle as above described it is adapted for general use, The connection of the axle to the yoke of the guidewheel by means of the low pendent frame and goose-neck forms an open-sided vehicle, which is specially convenient for use by women, and as the weight of the rider may be easily thrown upon the propelling apparatus at will with but little, if any, change of position, the ve hicle is adapted for use even by persons of but raiig' d with their free ends forward andthe opposite endspivoted to a frame projecting downwardandreai'ward from the axle, and, in combination therewith, a pair of springactiiated pulleys located on or near the pivotrod of the pedal-levers, and having I two sets of cords which are conn'eeted to pulleys on v the axle and to the pedal-leversat p'( )ints bef ween the ends of the same, substantially-as shownand described.

' 3. In a tricycle, the combination, with the main axle of the vehicle and the yoke of a front guide-wheel, of a connecting-frame projecting downward and rearward from the axle, and having a goose-neck adapted to incline the yoke toward the seat, a pair of pedal-levers pivoted to the lower part of said fra1ne,- the cord-retracting pulleys located on or near the pivot-rod of the levers, and the cords connected to pulleys on the axle and to thelevers at points between the ends of the same, sub stantially as shown and described, and for the purpose set forth.

4. In a tricycle, the combination, with the axle and the two sets of driving-cords, of the pulleys having two or more peripheral grooves of different diameters, and recesses forpass ing the cords across from one groove toa'nother, substantially as and for the purpose specified.
