' SPECIFICATION forming part of Letters Patent No. 433,542, dated August 5, 1890.

Application filed December 28, 1889. Serial No. 335,230. (No model.)

To all whom t may concern.-

Bc it known that I, PETER SCHAEEER, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Velocipedes, of which the following is a specication, reference being had therein to the accompanying drawings.

1o This invention relates to velocpedes, and more particularly to tricycles; and it has for its object to provide such a vehicle in which one, two, or more persons seated thereon will transmit motion to the dri ving-wheels by rock- :5 ing the seat to and fro in a manner to impart a fast speed thereto with an easy movement; and with that object in View my invent-ion consists of the novel devices and combinations of devices hereinafter described, and

2o specifically claimed.

In the accompanying drawings, Figure 1 represents a section al elevation of the tricycle from line :n a' in Fig. 2. Fig. 2 is a plan view ot' the same, the seat being removed. Fig. 3

is a transverse vertical section on the line of the main axles; and Fig. 4 is a sectional elevation from line y y in Fig. 2. Figs. 5 and 6 represent a sectional elevation and -a plan view of the tricycles, showing a modified device for transmitting motion from the rocking seat to the drive-wheel axle.

Corresponding figures of reference in the several figures of the drawings designate like parts.

The main axles 1 and 2 have each rigidly mounted upon one end a main drive-wheel 3,

and are journaled to beaxiallyin linewith each other in the side bearings 4, and with their abutting ends in central bearing 5 of the rear portion of the frame. This frame is formed longitudinally of two side bars 6 and one central bar 7,bent stair-like, to be lower in front, and these three bars are transversely connected by rear bar 8 and front bar 9 to be rigid, and to the front bar 9 is secured the lower end of agoose-neck-shaped bracket 10, having to its upper forwardly-curved extremity a vertical hub bored to receive the upper trunnion of a bifurcated standard 11, into 5o which is pivoted the pilot or steering wheel 12. This frame thus supported on three wheels has secured between the vertical portions of Vbars 6 and 7 and the bracket 10 a platform or foot-board 13, which may be adjustably fixed for a more or less elevated position to accommodate different-sized occupants.

Upon each axle 1 and 2 is loosely pivoted a sleeve 22, upon one end of which is rigidly mounted a disk 14, and upon its opposite end is rigidly mounted a sprocket-wheel 23, and 6o upon each sleeve 22, intermediate of disk 14 and sprocket-wheel 23, is loosely pivoted the hub of a semi-wheel 15, and against the opposite side of disk 14 is loosely sleeved upon each axle 1 and 2 a semi-wheel 16, and the 65 semi-wheels 15 being radially smaller have teeth out in the outward edges of their rims, while the larger semi-wheels 16 have teeth cut in the inward edges of their rims, both engaging with pinions 17, rigidly mounted 7o upon a shaft 1S, journaled in suitable bearings against the rear edges of the vertical portion of the framebars G and '7 .in a manner that a rocking movement of one of the semiwheels 15 or 16 will transmit a reverse rock- 7 5 ing movement to the other semi-wheel. The cap portion of the hub of each semi-wheel 15 and 16 is provided with a radial arm 19, having a small disk 20, eccentrically pivoted upon a crank-pin at the upper ends of such 8o arms 19, which moving over disk 14 in a forward direction will take frictional hold ou such disk 14` to move with it, but moving in a backward direction such disk 2O will release its hold on disk 14, whereby a noiseless movement is produced that will operate upon disk 14 in the same. manner as a pawl upon a ratchet-wheel. It will thus be readily seen that a rocking movement imparted to semi-Wheel 16,by means ot' shaft 1S and pin- 9c ions 17, will impart a similar movement in au opposite direction to semi-wheel 15, so that the disks 2O of the arms of the two semi-wheels 15 and 1G will alternately grip the disk 14, imparting to it a continuous rotating' move- 95 ment iu one direction. Upon the diametrical bar of the two semi-wheels 16, at the'opposite sides of the tricyole, are secured the legs of a seat 21, provided with a back and with armrests, and being of the desired width for one loo or two occupants, who when seated will rest their feet upon foot-board 13. This seat 21 is fixed upon semi-wheels 16, sufficiently more toward the front thatthe weight of the occupant will makesuch seat rock forward and that by the force of his legs the occupant will recline the seat backward, thus producing a to-and-fro movement of such seat and of the semi-wheels 16 and 15 for rotating disk 14.

Close to the cent-ral bearing 5 is loosely mounted upon each' axle 1 and 2 a sprocketwheel 24, and the sprocket- wheels 23 and 24 are provided with clutch-teeth on their opposing sides, and between these sprocketwheels 23 and 24 is sleeved upon each axle 1 and 2, and upon a feather rigid with the axle, a coupling 25, in a manner to rot-ate with the axle, but to be free laterally to slide thereon, each end of such coupling 25 being provided with clutch-teeth adapted to engage and couple with either one of the sprocket-wheels 23er 24, to turn with and drive the axle. Each such coupling of thetwo axles 1 and 2 is annularly grooved to engage the ring end ofa bar 2G or 27, the opposite ends of which bars'26 and 27 are pivotally coupled at opposite sides of its fulcrum-bolt to a lever 28, pivotedupon central bar 7 of the frame, with its rearward handle extending beyond bar 8 of the frame, on which the heads of.t\vo bolts 29 are provided for holding such lever 28 in either one of its two positions with the clutch 25, coupling either sprocket- wheels 23 or 24, which simultaneously of both axles 1 and 2 are thus made to move with these axles.

lTo be in line with sprocket- wheels 23 and 24 are loosely mounted upon shaft 18 sprocketwheels 30 and 31, both made rigid with each i other by a long hub, the sprocket-wheels 31 'stretched an endless chain 32,

being of larger diameter than sprocket-wheels 30, and over sprocketvheels 23 and 30 is and over` sprocket- wheels 24 and 31 is stretched an endless chain 33, whereby motion imparted to disk 14 and sprocket-wheel 23 will be transmitted to sprocket- wheels 30 and 31 by chain 32, and, again will be transmitted at a faster speed to sprocket-wheel 24 by chain 33, in a manner that by shifting the couplings 25 to engage wheels 23 the speed transmitted to the axles will be less than with shifting the coupling toengage wheel 24, so that the occupant can go at a slow speed while riding uphill, and when on a level road he can change the mechanism fora faster speed with the same rocking movement of the seat.

Upon the upper projecting end of the trunnion of the bifurcated standard 11 for pilotwheel 12 is rigidly secured a crank 34, connected by a rod 35 with another crank 3G of a sta-ff 37, pivoted in suitable brackets against the vertical part of one of the side bars 6 of the frame, and this staff 37 has to its upper extremity a handle 38, in easy reach of the occupant, by which h'e controls'the pilot-wheel for steering the vehicle.

Figs. 5 and 6 show a modication of the driving-gears for transmitting a continuous rotating movement to the axles from the rocking seat. In this device, instead of disk 14 and semi-wheels 15 and 16, is loosely mounted upon each axle an interiorly-toothed gearwheel 30, meshing with pinion 17 of shaft 18. The seat 2l is secured upon two swinging beams 40, loosely pivoted upon the axles, and the forward ends of these beams 40 have each pivoted a spring-controlled pawl 41, engaging the teeth of wheels 39. Rearwardlyextending arms 42, also loosely pivoted upon the axles and each provided with a springcontrolled pawl 43, are coupled each with the rear end of a beam 39 by chains 44, passed over pulleys 45, whereby a rocking movement of the seat 21 in one direction will transmit a rocking movement to the arms 42 in an opposite direction, and whereby one of the two pawls 4l or 43 will alternately be in engagement with one of the teeth of wheels 39, while the other pawl will be on its return movement sliding over the teeth therein, so as to impart a continuous rotating movement to such wheels. Upon shaft 17 are also rigidly mounted two sprocket-wheels 16, and

uponeach axle is rigidly mounted a sprocketwheel 47, and over each pair of sprocketwheels is stretched an endless chain 48, that will transmit motion from shaft 17 driven by pinion 18, and from wheels 39 to the axles l and 2. l

Vhile a single axle may be efficient, I prefer to provide an independent axle to each drive-wheel, whereby the tricycle will move over a curved road with more ease than with both wheels rigidly mounted upon a single' axle. Y
