SPECIFICATION forming pm of 'Leners Patent No. 323,052, aaa-a July 2a, laas.

Application filed November 1, 1884. (No model.)

To all whom it may oon/cern:

Be it known that I, JEFFERSON W. MATTE- SON, a citizen of the United States of America, residing at Hebron, in the county of Botter and State of Pennsylvania, have invented certain new and useful Improvements in Tricycles; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethey same, reference being had to the accompany-1 ing drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

. My invention has reference to tricycles, and it consists in the improvements hereinafter described and set forth, and then sought to be specifically defined in the claims.

In the accompanying drawings, forming a part of this specification, Figure l lis a side elevation of my improved tricycle. Fig. 2 is a rear and Fig. 8 a plan view of the same.

Fig. 4 is a sectional detail ony the dotted line :r x of Fig. 3. Figs. 5, 6, and 7 are detail views; and Fig. Sis a perspective view. a

The supporting-frame of the machine con. sists of a rod, A, which'is projected at its front end to form the horizontal portion a, which terminates in the loop b, designed to receive the shank c of the vertical yoke B, looped at its lowerend to receive the journals d of the guide-wheel C. The rod A is bifurcated to provide the rearwardly-extending portions A A, each ofl which depends down from. the horizontal portion a, and is then bent upward and rearward, each termihating at its rear end in a socket, e.

D D represent the rear carrying-wheels of the structure, the hubs d of which are mounted loosely on the stub-shaft d, the inner end of which shaft bears in the adjacent socket e, and is clamped therein by means of a screw, d, which pierces said said socket and bites the end of said shaft. Each hub d is pro` vided on its inner face with a ratchet-wheel, d', which is adapted on the forward rotation of said wheel to engage a pawl located on an adjacent sprocket-wheel, f,which is mounted loosely on the shaft d, but is held in position thereon by being Vretained between said ratchpierced by said stub-shaft c and is provided f et-wheel cw and a plate or guard, F, which is y on its inner side with a collar, f, which embraces said shaft and bears against the adjacent 'socket e, thereby insuring the proper lateraly position of the several parts mentioned. An arm, g, is secured on each of the rear portions of the rods A, so as to bear against the adjacent plate F and re-enforce the same against pressure. -A strap, g'fdepends from each rear portion, Al A, adjacent to its socket e, and is secured at its lower end to a horizontal plate or platform, G. A brace, h, is secured to each of the rods A A', near the front depressed portion thereof, and each of the said braces extends inward toward the center of the machine for the attachment of parallel rods h', the lower ends of which are secured to the platform Gr, the centers being braced by a strap, h, which is looped at its ends to embrace said rod so as to play vertically there.

on. A second strap, 717, is located near the bottom of said rods, so as to play vertically thereon. A vertical rod, H, is connected to the straps WN, as shown in. Fig. 2, and terminates at its upper end in a handle, hthe front face of said barbeing arranged so as to present a vertical series of rack-teeth, hm.

A sleeve, I, is located upon the depressed portion of each of the sections A A, as indicated most clearly in Fig. 4, and each of the said sleeves is de'signedto form the en'd bearing for a transverse shaft, J, which has loosely mounted on each end a sprocket-wheel, J provided on itsv inner face with a hub, j, having a series of teeth, j. A gear-wheel, K, is mounted loosely on the said shaft J immediately opposite each vertical rack-bar I-I, so as to mesh with the teeth thereof. A sleeve, K', is located on the shaft J adjacent to each of the gear-wheels K, and the said sleeve is rigidly secured to said shaft by means of a setscrew, k, one end of said sleeve K being arranged to present a ratchet-face, 7s, designed to be engaged by a dog, k, located in a recess in the adjacent side face of the gear-wheel K when the said gear-wheel is rotated in a forward direction. Two vertical series of paralvided with a transverse series of straps, m

m, arranged on said rods,simi1ar to the straps hh, and having secured thereto a vertical rack-bar, M, the rear rack -face of which meshes with a gear-wheel, N, mounted loosely on the shaft J, and designed-to rotate said shaft by means of a central sleeve, K, provided at its ends with ratchet-faces a, adapted to beengaged by pawls on the adjacent gear-wheels N When said gear-wheels are rotated in a forward direction. A spring, o, embraces one of the rods of each pair m m', so as tomaintain the straps of each pair about the upper portions of said rods. The lower ends of each of the vertical rack-bars M carry a pedal, O.

l? represents astud located on the horizontal portions a of the rod A, and forming the pivotal bearing for acasting, P', the front face of which is provided with a series of rackteeth, p, arranged in the form of an arc .and adapted to mesh with the teeth of a gear-pinion, P, bolted on the upper end of the shank c of the yoke B. The casting B has pivoted at its rear portion a hand-lever, p, which is designed to engage one of a series of notches formed in a curved bar, P, supported on the rod A by means of a curved brace, 19. A plate, q, projects from each rod A A and forms the fulcrum on which to pivot the front end of the lever Q, provided with a pin on its under side designed to engage one of the teeth` j in the adjacent wheel J.

R R represent two plates, which are pivoted on the upper side of the socket e, as shown in Fig. 3, and which when arranged as shown in said figure, form conjointly a double seat, each section It R' being provided with a bent wire rod, r, to serve as aback for said seat. A spring-brace, s, is secured at one end to the under side of each of the seat-sections R R', while its other end is perforated for the engagement of a pin, t, depending from the .under side of each of the sockets e.

A suitable fastening device, a, is designed to secure the seat-sections together in the positionsillustrated in Figs. 3 and V7.

A link-chain serves to transmit motion from each wheel J to each sprocket-wheelf.

The operation of the device is as follows: Two persons are each to manipulate one of the bars H and M. It will be obvious that as each bar M is depressed it will rotate the adjacent gear-wheel N, so that the pawl of the same will engage the ratchet-face of the L sleeve K and revolve the shaft J, and consequently rotate the carrying-wheels D of the machine. l rlhe successive lifting of the bar H will effect the like rotation of the adjacent gear-wheel K, and continued revolution of shaft J and carrying-wheels D. The operator effects the return of the bar H to its first position by means of the handle h thereof, the reverse revolution of the gear-wheel K resulting in a disengagement of said wheel from the adjacent sleeve, K', thereby preventing any reverse movement of the shaft J. The

.springs o effect the return of the bars N to lto manipulate the lever p, so as to swing the casting and effect a partial turning ofthe guidewheel C in either direction.

The guard-plates F serve as a protection against liability of injury to the operator by contact with the revolving wheels D.
