TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 373,282, dated November 15, 1887.

Application filed August 20, 1887. Serial No. 247,429. (No model.)

To all whom it rota/7, concern.-

Be it known that I, HERMANUS THEODORE FRIE, of Curagoa, Dutch West Indies, have invented a new and Improved Tricycle, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved tricycle which can be easily and conveniently propelled at a high rate of speed without much exertion on the part of the operator.

The invention consists of a rocking-chair located on the frame and operating at its free end on a segmental gear-wheel connected by a train of gear-wheels with the axle of a drivingwheel. n

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of my improvement. Fig. 2 is a similar view of the same with parts removed. Fig. 3 is a sectional side elevation of a modified form of the device for transmitting power. Fig. 4 is an enlarged vertical crosssection of my improvement on the line an c of Fig. 2. Fig. 5 is a sectional plan view of the same on the line yy ofFig. 2. Fig. 6 is a plan view of the brake mechanism. Fig.

. 7 is a sectional side elevation of part of the same. Fig. 8 is a face view of'the foot-wheel for the. steering apparatus. Fig. 9 is a vertical cross-section of the same, and Fig. 10 is a detail View ofthe spring-pinion.

Of the two main driving-wheels A A, the latter is loosely mounted on the spindle B of the frame B, of suitable construction, and the other driving-wheel, A, is secured on ashaft, O, mounted torotate in suitable bearings formed on said main frame B. On the inner end of the shaft O is secured a gear-wheel, D, which meshes into the internal gear-wheel, E, mounted to rotate loosely on the shaft E, held on the main frame B.

On the internal gear-wheel, E, is formed an external gear-wheel, F, which meshes into the pinion G, loosely mounted on the shaft H, p

. bearings on the main frame B.

whichis mounted to rotate in'suitable bearings formed on the main frame B. The pinion G is connected with a clutch held on the end of the arm I, pivotally connected with one of the spokes of the fiy-wheel J, secured to said shaft H and provided on its hub with a ratchetwheel, K, with which engages a pawl, L, pivoted on the gear-wheel N, mounted loosely on said shaft H and meshing into the gear-wheel O, secured to the shaft 0, mountedin suitable The gear-wheel O meshes into the pinion P, secured to the shaft P, mounted to rotate in suitable hearings on the main frame B, and on said shaft P is coiled a spring, P fastened by one end to the in its bottom edge with a V-shaped groove fitting on the V-shaped top edge of the longitudinal bar B secured to themain frame B.

Each end of each runner of the rocking-chair R is provided with a friction-wheel, R", rolling on a segmental arm, B secured to the main frame B, so as to prevent the rockingchair R from moving laterally, butpermitting a free rocking motion.

To prevent the runners of the rockingchair R from jumping the longitudinal bars B", I provide the rollers B connected with each other on each-side by the rods B", said rollers R engaging, respectively, the top edges of the runners and the bottom edges of the longitudinal bars B. These rollers B'" travel on the lowest or contact points of the runners of the rocking-chair B, and thereby prevent the runners from jumping the respective tracks, but permit a free and easy rocking motion of the rocking-chair R.

The lower end of the segmental gear-wheel Q is pivotally connected bya link, S, with the rear end of the foot-lever T, fulcrumed at T to the main frameB and carrying at its front end a foot-piece, T operated on by the foot of the operator seated in the rocking-chair R.

IOC

The train of gear-wheels and connected parts above described are preferably covered by a hood, U, of any suitable material or shape, so as to prevent the operator from coming in contact with the train of gear-wheels, and also to prevent dust from settling on the said mechanism.

The fly-wheel J is provided on part of its rim with a ratchet-wheel, J, which engages a pawl, J held adjustably on the hood U in such a manner as to move said pawl J in or outof contact with the ratchet-wheel J. The pawl J serves to prevent the fly-wheel J from running in a wrong direction as long as the operator desires it. On part of the rim of the fiy-wheel J operates a brake-shoe, V, secured to the lever V, fulcrumed at V to the hood U, and provided at its rear end with a handle, V", at the side of the rocking-chair, so as to be within convenient reach ofthe operatorseated in the rocking-chair R.

The steering-wheel V is located in front of the drivingwheels A and A, and is mounted on the npwardly-extending rod W, having its bearing in the front end of the main frame B. On the upper end of said rod W is secured the bevel gear-wheel X, meshing into the pinion \V, fastened on the horizontal shaft \V, mounted to rotate in suitable bearings formed on the main frame B, and the inner end of said shaft \V carries the foot-wheel \V pro vided on its inner face with notches or offsets W, so as to permit the operator to turn said foot-wheel W with his foot conveniently, whereby a turning motion is imparted to the vertical rod \V, so that the steeringwheel \V is turned at an angle to the main drivingwheels A and A, whereby the entire apparatus is steered.

The operation is as follows: The operator is seated in the rocking-chair R, and by rocking in the same he imparts by the pin It a downward motion in the direction of the arrow at to the segmental gear-wheel Q, which rotates the pinion P, and the latter imparts a similar motion to the gear-wheel O, which transmits its motion to the gear-wheel N, rotatingloosely on the shaft II, and said gear-wheelNimparts by its pawl L a rotary motion to the ratchetwheel K, so that the fly-wheel J, on which said ratchet-wheel K is formed, is turned in the direction of the arrow b. The fiy-wheel J, by means of the clutch-arm I, imparts a rotary motion to the pinion G, mounted loosely on theshaft II, and said pinion G transmits its rotary motion to the external gear-wheel, F, which, on account of being connected with the internal gear-wheel, E, imparts a rotary motion to the pinion D, secured to the shaft 0, and the latter, which carries the main drivingwheel A, thus imparts a rotary motion to the said main driving-wheel Ain the direction of the arrow c, and thereby propels the machine forward in the direction of the arrow d. As soon as the downward motion of the rockingchair R is completed and the operator rocks backward, the segmental gear wheel Q is moved to its former position by the compressed coil-spring I which had been wound up by the downward motion of said segmental gearwheel Q. It will be seen that the return movement of the segmental gear-wheel Q, the pinion P, and the gear-wheel 0 does not affect the motion of the fly-wheel J, as said gearwheel Q only imparts a motion in the direction of the arrow 1) to said flywheel J by the gearwheel N, carrying the pawl L, engaging the ratchet-wheel K. If the operator desires, he can press his foot on the foot-piece T on the downward motion of the rocking-chair R, thus assisting the segmental gear-wheel Q in its downward movement, thereby increasing the transmission ofthe power to the main drivingwheel A, as before described. The operator can apply the brake V whenever desired to the fly-wheel J by raising the handle V of the lever V, so that the shoe V engages the rim of said fly-wheel J.

When the veloeipede is designed for carrying freight, I prefer to arrange the transmission of power from the gear-wheel O to the gearwheel N in the manner iliustrated in Fig. 3, in which the gear-wheel O meshes into a rack, 0 carrying a piston, 0, operating in a small cylinder, 0, containing water and secured to the main frame 13. Said small cylinder O connects at its lower end with a larger cylinder, N, in which operates a piston, N", connected with a rack, N, meshing into the gear-wheel N, which latter, however, is notin mesh with the gear-wheel 0, but is connected with the fly-wheel J in the manner above described. It will be seen that when the gearwheel 0 is rotated, as above described, by the action of the rockingchair R the piston O" is forced downward, so that the water in the cylinder O" presses thepiston N upward, thereby imparting motion by its rack N to the gearwheel N. The difference in the sizes of the gear-wheels O and N and of the cylinders O and N causes a strong transmission of power applied at a slow rate of speed.

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