IMPROVEMENT IN MOTORS.
Specification forming part of Letters Patent No. 124,829, dated March 19, 1872. I
To all whom it may cont-emu;
Be it known that I, SYLvnsrER L. LANG DON, of New Orleans, Louisiana, have invented certain new and useful Improvements in Motors, of which the following is a specification:
The Nature of the Invention.
The nature of my invention consists in the construction of a motor for the propulsion of cars, operating cotton-gins, and all kinds of machinery where a powerful and continuous rotary motion is required; and consists in, first, the use of levers of suitable construction, which are attached or connected by means of cranks to gear-wheels in such a manner that by operating the levers a rotarymotion is imparted to the wheels, and from them, by means of any suitable connections, to the machinery which it may be desired to operate; second, in the arrangement of the cranks in such relation to each that while one is on its deadpoint the other will be on its reverse deadpoint, so as to form a fulcrum for a lever to put them in motion, the cranks being always in parallel lines with each other; third, in slotted standards, in which the levers are supported, so as to keep them in place, and at the same time to allow their full weight to be thrown upon each crank on the down stroke; fourth, in the general arrangement and combination of devices, to be more fully described hereafter, by which I obtain a cheap and simple motor of great power by the exertion of comparatively little force.
In the accompanying drawing, Figure 1 is a view of my invention as applied to propelling street or other cars. Fig. 2 is a side elevation A represents the frame of my machine, which may be constructed of any desired shape or Extending upward from each side of this frame there is an upright standard, B, the upper ends of whichv are slotted downward to any suitable distance, so as to receive the steadypins 0:, of the levers G, and to allow the weight of the levers to be used in giving additional power on the down strokes to the cranks. The levers G are balanced in the standards B, so as to give the longer end to the operator, and
are provided with holes I), so that the connecting-rods D, placed at equal distances from the standards B, can be madeto make a longeror shorter stroke, as may be desired. These connecting-rods D have their lower ends attached to cranks F, one of which is placed on each shaft in such relation to each other that when one is on its dead point or center the other will be on its reverse dead point or center, and thereby become the fulcrum for the other. The
shafts G, on which the cranks F are secured,
have each a gear-wheel, H, attached to it, having an equal number of cogs, and which receive the power from the levers and transmit it to the machine which is to be operated' These wheels, in revolving, keep the cranks always in the same relative positions, and, if desired, one of the wheels may have a few more cogs than the other. These two Wheels may either gear together, or an intermediate smaller one, I, may be placed between them and receive the power from both, and by means of a suitable connecting device, J, transmit it to any desired point. When it is desired to use this motor for propelling street or other cars this wheel I is placed upon the axle K of the car, and the power of the two wheels H will be exerted in propelling the car forward.
This smaller wheel, when the motor is applied to running machinery, may be dispensed with, if desired, the two wheels H being made to mesh with each other, and the power transmitted from them by any suitable device. To each one of the levers O, at its outer end, there is secured a connecting-rod, L, which have their lower ends connected to the cranks Non the shaft 0. These cranks are placed at right angles to each other, so that when the shaft 0 is revolved by the operator by means of the hand-wheel P or any other suitable operating device the levers are alternately raised and depressed, thereby communicating a rapid and powerful motion to the wheels H at comparatively little expenditure of power.
When this motor is applied to cars the parts may be arranged as shown-the wheels arranged, as shown, under one end, and the levers extending along inside or outside.
Either two or four cranks may be used; when four are used, as shown in the present instance, they may be placed on the shafts, so
that the two front cranks will be on the top center at the same time, and the rear ones on the bottom center, in which case the two levers would work together, instead of alternately, only one crank then being used on the shaft 0.
The levers C may be extended at both ends, and may be placed underneath the machine as well as above, if so desired.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The combination and arrangement of the gear-wheels H with the reversed cranks F, substantially as shown and described.
2. The rods D, secured to cranks having reversed centers placed on parallel lines with
