SPECIFICATION forming part 0f Letters Patent NO. 653,452, dated. July 10, 1900.

Application led January 30,\1900. Serial No. 3,315. (No model.)

To all whom, it may concern:

Be it known that I, FRIEDRICH KLEINvo# GEL, a citizen of the United States, residing at No. 738 Central avenue, Newport, Kentucky, have invented certainnew and useful Improvements in Lever-Driven Mechanisms; 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 use the same.

This invention relates to lever driven mechanisms mainly intended for the propul-v sion of vehicles.

It comprises a crank-shaft, pedal-levers, a means for imparting motion from said pedallevers to the crank-shaft, a means for returning said levers to their operative position, and means for transferring motion from the crank-shaft to a driven shaft. L

It further consists in certain details of construction, all as hereinafter described and claimed.

In the drawings which accompany and form a part of this specification, and to which reference will behad in the course of the following description, I have shown a preferred embodiment of my invention.

Figure 1 is a side elevation of a lever-propelled vehicle, showing its general arrangement. Fig. 2 is a vertical'section through the same; and Fig. 3 a top plan view, the'le-V, ver system being omitted for clearness.

Like reference-numerals denote like parts throughout the several views.

1 designates a rectangular tubular frame curved and bent upwardly at its forward end and supporting the head-'post 2, in which turns the steering-rod 3, retained in its seat by clamp 4, and having the handle-bar 5. The head-post is braced by rods 6, connecting with the cross-rail 7.

8 8 are journals connected with the frame, in which is adapted to rotate the axle 9, bearing the traction-wheels 10. Two parallel rods l1 are arranged midway of the frame and conneet the cross-rods 7 and the rear extremity 12 of the frame and serve to carry the superstructure carrying the gearing. This may comprise the plates 13 13, bolted or otherwise secured to rods 1l and united at their extremities. In the front portion of said plates is mounted the crank-shaft 14, carrying the cranks 15 16 and also the sprocket-wheel 17,

located between said plates and connected by chain 18 with sprocket-wheel19, mounted upon the axle 9.v An additional shaft 2O is mounted in said plates and carries the balance-wheel 21 and 'sprocket-Wheel' 22, connecting with sprocket-Wheel 19 through the medium of chain 23, as clearly shown in Figs.

2 and 3.

Wheels 24 25 are rigidly mounted on rocking shafts 26 26, carried in suitable bearings 27 upon the frame 1 and plates 13 13. Each of said wheels is provided on its lower periphery with an angular block 28, the baseline 'of which is tangent to the periphery of the wheels, as seen in Figs. 1 and 2. 'A chain 29 or' its equivalent is connected at one end to the periphery of said wheel at a point in rear ofrv the angular block 28 and is always guided upon the latter by lugs 30, the chains being connected at their opposite ends to links 3l 32, engaging, respectively, with crank-arms 15 16. The frame 1 is further provided on either side thereof, near its rear portion, with inverted-V-shaped frames 33 33, which are braced and connected with each other byV transverse rods 34 35, Fig. 2. 'Ihe rod 84. is connected to the rear portion 12 of the frame 1 by parallel rods '36. The latter serve to carry the rear ends ofthe seat-sup-A port, consisting of two forwardly-extended members 37 38, separated at their front ends bya coil-spring 39 provided. The lower member 37 is stationary upon the saddle-post, the latter consisting of two vertically-extended rods 40, borne upon rods 11. The top member 38 carries the saddle 45 and below the same a bolt 46, which passes loosely through the bore 42 and carries upon its lower threaded portion a block 41, adapted to be vertically reciprocated upon the spring 43, between the rods40. The spring 43 is mounted upon the block 44, secured between the rods 40 to the lateral plates 13.

The pedal-levers 47 48 are pivoted, as at 49, upon pins connecting the V-frames y33 and rods 36 and are connected by links 50 to levers 51, fulcrumed at 52 upon transverse rod IOO 34. Each of levers 51 has pivoted at its for- 55 to one of the spokes of wheels 24 25, contiguous the angular blocks 2S. .Another lever 56 is pivoted substantially at its middle upon a pin 57, carried in rods 58, connecting the transverse rods 34 35. The same construction is duplicated upon the other side. The obliquely-extended levers 56 are connected at their upper ends by links 59 to levers 51 and are connected at their respective lower ends by staples G0 to forked members 61, which in turn are pivoted, as at G2, to the peripheries of wheels 24 25, respectively, the last connection being in a horizontal plane with the pivot connection 55.

The machine may be provided with any suitable steering-gear. In the present instance I have shown a steering-wheel 63, mounted in a easter 64, centrally of the rear portion 12 and having a laterally-extended pin G5, connected by chains 6G with rods 67, which cross each other and extend to the forked end GS of steering-rod 3, to which they may be connected by links 69.

It will be seen that upon depressing one of the pedal-levers 47 48 the respective top lever 51 will be drawn down and will operate to transmit motion through the medium of lever 53 to wheel 24, giving the same a forward rocking motion, whereby the crank-shaft 14 is rotated through its arm 15 and chain 18, the rotation being made continuous by the crank-arms 15 16 being arranged at an angle of ninety degrees to one another. This results in an opposite rocking motion of wheels 24 25. Motion is transferred from crankshaft 14 to the axle 9 through the medium of sprocket-wheel 17, chain 18, and sprocketwheel 19, the movement being regulated by balance wheel 21, operated by sprocketwheel 22, connected with sprocket-Wheel on axle 9 by chain 23.

While I have described my improved mechanical movement as associated with a vehicle which may take the the place of a bicycle or similar machine, especially where intended for travel on badly-graded roads or which may have attached thereto any wellknown means for use as a eultivator, it is obvious that its use is not restricted to any special mechanism or devices.

IIaving thus described my invention, I claim- 1. In mechanism such as described, a crankshaft, wheels mounted upon separate axes and having a partial rotatory or rocking movement in opposite relation to each other, segments secured to the lower peripheries ol' said wheels, and chains guided upon said segments and connecting the crank-shaft and Wheels, pedal-levers pivoted at 'their rear extremities to a stationary part, a series of levers operatively connecting said pedal-levers and wheels for imparting a rocking movement to the latter, means for transferring motion from the crank-shaft upon a driven shaft, and including a balance-wheel to regulate the movement, substantially as specied.

2. In a vehicle, a frame for the vehicle, a revoluble front axle, traction-wheels upon said axle, a crank-shaft, shafts journaled in bearings near the back of the frame, a Wheel upon each shaft, having each a partial rotatory or rocking movement in opposite relation to the other, segments secured to the lower peripheries of said rocking members or wheels, and chains guided upon said segments and connecting the crank-shaft and wheels, pedallevers pivoted to the rear of the frame, a series of levers operatively connecting said pedal-levers and wheels for imparting a rocking movement to the latter, and means for transferring motion from the crank-shaft upon the front axle, including a balance-wheel to regulate the movement, substantially as described.

In testimony whereof I aix my signature in presence of two witnesses.

FRIEDRICH KLEINVOGEL.
