ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for converting reciprocal linear motion to continuous rotary motion. The device is particularly usefull for converting reciprocal motion of a piston engine arrangement into rotary motion of an output shaft for a vehicle.
2. Description of the Prior Art
U.S. Pat. Nos. 2,578,559; 3,347,478; 3,465,602; 3,572,140 and 3,661,019 disclose devices for converting reciprocal motion to rotary motion or vice versa. U.S. Pat. No. 2,578,559 discloses a flywheel, which is said to maintain a nearly constant rotational shaft velocity in a reciprocal to rotary conversion device having only one power stroke. U.S. Pat. No. 4,282,442 discloses a basic conversion machine in two embodiments which are used in the present disclosure.
SUMMARY OF THE INVENTION
In a device in accordance with the present invention, the reciprocal linear motion of an input member is converted into alternating rotary motion of a drive member such as a drive shaft or a drive gear. U.S. Pat. No. 4,282,442 issued on Aug. 4, 1981 describes such a device and is therefore incorporated by reference into the present application in support of the embodiments herein disclosed for detailed teachings. The present invention further teaches certain advances in the art within several embodiments as described in detail and claimed in the following.
