Description: |
| Claim:
The purpose of this invention is to provide an improved motor in the shape of a gas or oil engine for association with and to assist in propelling a bicycle or other vehicle. One specific purpose kept in mind as a motive for the invention is to provide a motor adapted to operate with the least possible intervening mechanism upon the driving-wheel of the vehicle and at the same time to prevent the excessive strain upon the parts which results when the mechanical connections from the piston-rod of the motor to the wheel are exposed to the shock of the explosion and the resultant almost instantaneous movement of the piston. To avoid making such direct connection heretofore, motors have been constructed whose prime shaft-that is, the shaft having immediate crank connection with the piston-has a high rotary speed, from which proper speed-reducing train extends to the vehicle-wheel. The objections to such train are obvious, and the necessity of a high rate of motion for the engine and its prime shaft which is involved in that mode of construction is seriously objectionable; and my invention as to this point consists in causing the action of the piston under the force of explosion to store up power by coiling a spring whose uncoiling at any speed and at any time drives the vehicle-wheel. |
