SPECIFICATION forming part of Letters Patent No. 304,960, dated September 9, 1884.

Application filed February 27, 1884. (No model.)

To all whom it may concern:

Be it known that we, CHARLES A. RODINE and JOHN G. MALMGREN, citizens ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented cer-V tain new and useful Improvements in Motors, of which the following is a specification, to Wit:

Thisinvention relates to an improvement in motors,- and it consists in the peculiar construction and arrangement of the same, substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure 1 is a side elevation of a vehicle having our motor applied. Fig. 2 is a bottom,

plan view of the same. Fig. 3 is a detail view of the mechanism of the motor, and Figs. 4 and 5 are details of parts of the device.

A represents a vehicle of an ordinary and well-known kind, to which our motor is applied. Below the body of the vehicle is secured a frame, I), in which are journaled a series of gearwheels constituting the main portion of the motor. C represents a handleverprovided at its lower end with a ratchet-wheel, C', secured to a shaft, c, and with which a spring-pawl, d, upon the lever engages, as in Fig. 4. Upon the shaft c is a gear, C2, meshing with a pinion, c, upon a second shaft, which latter also carries a gear, Ci, engaging a pinion, c3, upon a third shaft journaled in the frame, as will be fully shown in Fig. 3. This shaft is also provided with a gear, C", meshing with and giving mot-ion to a pinion, c4, upon a shaft, D, .which also carries a iiy or balance wheel, D. In the drawings this shaft D is provided with two cranks, d d, connected by pitmen DL with the rear aXle,

I D3, which is also cranked, and has rigidly secured to it the driving-wheels D4, as shown. W'e donot, however, desire to confine ourselves to the crank-and-pitman connection between the motor and the driving-axle, but for light carriages will use a chain-belt connection with driving pulleys upon the shaft D and axle D, as will be at once understood.

For heavy work and climbing steep grades, we hinge to each pitman Dia push-arm, E. having its lower end formed withteeth or serrations e e, as in Fig. 1. This arm is normally lifted and secured to the pitman, but when desired for use its rear end is dropped upon the ground, and, engaging therewith, aids in propelling the vehicle forward. This will not be necessary, however, except uponheavily-loaded vehicles upon steep grades.

The lever C is provided with a spiral spring, F, attached to the rea-r side of the lever, and also to the body or bed of the vehicle, and

while the lever is easily pushed forward and the force of this spring overcome, by reason of its length of leverage, the spring exerts a force in pulling it back again, which,by means of the intermediate train of gearing, is communicated to the wheels of the vehicle and moves it forward. The lever is pushed forward by the attendant as often as may be necessary, and the device is thus kept in motion.

The front axle, G, of the vehicle is pivoted as usual, and its ends connected by a liexble chain or rope, g, running over pulleys g, under the rear of the bed. This cha-in or cord is connected to the lower end of a hand-lever, G', which is pivoted upon the side of the bed or body and provided with a thumb-latch, g2, engaging with a notched segmentrack, G2, by which the machine is guided in any direction, and is held in any position by engaging with the rack, as will bc at once seen by reference to Fig. l.

Upon the frame which supports the gearing is pivoted, at one end, a brake-bar, H, having a shoe, h, adapted to bear against the balancewheel, and the free end of this bar is by a cord, h', connected to a foot-pedal, H, which, on being pushed down, draws forward the bra-ke against the ily-wheel and stops the machine at any time. The brake-bar is drawn back again by means of a spring, h2, secured to its free end, as in Fig. 2.

The wheels D1' D" of this vehicle are formed with a iiange, d, and are thus enabled to run with equal facility upon. the bare ground or upon a car-track, a tire, of the same form being placed around them for protection, as usual.

An alarm-bell, fi, may bc attached and op- IOO eratcd by a foot-lever, and, if found desirable, the lever C maybe extended below its shaft and be supplied with asccond torsion-spring, similar in all respects to the first, and working in the opposite direction, which will of course increase the power and speed of the inachine.

It will seldom be found necessary to reverse the motion of this niotor; but should it be desired, the lever may be slipped oil" the shaft and reversed, when the ratchet will of course act in a reverse direction.

It is obvious that the peculiar arrangement of gearing shown is not an arbitrary one, but maybe varied somewhat-as, for instance, the gearing maybe laid horizontal and connected to the ratchet-lever, to operate in the saine manner, and occupy less rooin below the bed i of the vehicle.

Having thus fully described our invention, what we claim as new(` and desire to sccurc by Letters Patent, is-

1. The frainc A, having the cranked axle D", and the lever C, with its spiral spring F, in

combination-with an intermediate system of 25 gearing connected to the axle by pitinen, substantially as and for the purpose set forth.

2. The combination, with the balance-Wheel B', of the brake-lever H, having a retracting spring, h2, and the cord h, and foot-pedal H', substantially as and for the purposes set forth.

3. The lever G, connected by a ratchet and pawl to the shaft c, and provided with a torsion-spring, F, in combination with the gearing G2 C C, connected to the driving-axle, substantially as shown and described.

In testimony whereof we afiix our signatn res in presence of two witnesses.
