Abstract

Abstract An apparatus and method of converting reciprocating motion to rotary motion. The apparatus includes an endless rack assembly reciprocally mounted for reciprocating motion through a stroke; a cooperating pinion rotatably mounted on a rotatable element operative to track the rack assembly; and lock means cooperating with said rotatable element for blocking rotation of said element during a substantial portion of said stroke. The method comprises reciprocating the rack assembly under control of a power source; causing a first pinion of a rotatable pinion assembly which cooperates with the endless rack assembly to traverse the rack assembly continuously as said rack assembly reciprocates effective to rotate the first pinion continuously in a given direction; using the first pinion to drive a second pinion of the pinion assembly; and using the second pinion to drive a flywheel and an output shaft thereby rendering power output uniform throughout a given cycle.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 214 words
An apparatus for converting reciprocating motion of varying potential to rotary motion of uniform potential comprising: a base with a pair of support members integrally bound to said base and each support member including a structure defining a common shaft aperture; a common shaft rotatably lodging within the common shaft aperture of each of the support members; a flywheel means bound to an end of said common shaft; a rotatable element having a structure defining a pinion aperture and an element aperture wherethrough said common shaft rotatably passes for mounting thereon said rotatable element; an endless rack assembly reciprocally mounted on said common shaft for reciprocating motion through a stroke; a cooperating pinion assembly rotatably mounted through and within the pinion aperture of said rotatable element operative to track the endless rack assembly; and lock means secured to said base cooperating with said rotatable element for blocking rotation of said element during a substantial portion of said stroke; said rack assembly is formed with a cam element and the rotatable element carries a cam follower means for maintaining the pinion assembly in contact with the rack assembly; the surface of the cam element is so contoured such that the cam follower means is operative to move the rotatable element to disable the lock means.
Claim 2
Independent Claim 214 words
An apparatus for converting reciprocating motion of varying potential to rotary motion of uniform potential comprising: a base with a pair of support members integrally bound to said base and each support member including a structure defining a common shaft aperture; a common shaft rotatably lodging within the common shaft aperture of each of the support members; a flywheel means bound to an end of said common shaft; a rotatable element having a structure defining a pinion aperture and an element aperture wherethrough said common shaft rotatably passes for mounting thereon said rotatable element; an endless rack assembly reciprocally mounted on said common shaft for reciprocating motion through a stroke; a cooperating pinion assembly rotatably mounted through and within the pinion aperture of said rotatable element operative to track the endless rack assembly; and lock means secured to said base cooperating with said rotatable element for blocking rotation of said element during a substantial portion of said stroke; said rack assembly is formed with a cam element and the rotatable element carries a cam follower means for maintaining the pinion assembly in contact with the rack assembly; the surface of the cam element is so contoured such that the cam follower means is operative to move the rotatable element to disable the lock means.
Claim 3
Dependent Claim 58 words
The apparatus of claim 1 wherein said pinion assembly comprises a pinion shaft rotatably mounted through the pinion aperture of said rotatable element, a first pinion gear fixed to one end of said pinion shaft, and a second pinion gear fixed to the other end of said pinion shaft to be rotationally driven by the first pinion gear.
Claim 4
Dependent Claim 39 words
The apparatus of claim 2 additionally comprising a common shaft gear bound to the common shaft and meshing with the second pinion gear to be driven by same in order to cause the common shaft to turn the flywheel.
Claim 5
Dependent Claim 51 words
The apparatus of claim 3 wherein said rotatable element has a structure defining a pair of opposed notches, said lock means engaging one of said notches through a given stroke until the cam follower means contours an end of said cam element operative to disable the lock means from a notch.
Claim 6
Dependent Claim 30 words
The apparatus of claim 4 wherein said rack assembly comprises an endless rack gear meshing with and cooperating with the first pinion gear and driving same with a given stroke.
Claim 7
Dependent Claim 34 words
The apparatus of claim 5 wherein said flywheel includes a momentum which causes the rotatable element to rotate the pinion assembly around and underneath the rack assembly after the lock means has been disabled.
Claim 8
Dependent Claim 27 words
The apparatus of claim 6 wherein said rotatable element rotates the pinion assembly until the lock means engages one of the opposed notches on said rotatable element.
Claim 9
Dependent Claim 30 words
The apparatus of claim 6 wherein said base has a structure defining an elongated slot for passing said second pinion gear when said pinion assembly is in the inverted position.
Claim 10
Dependent Claim 224 words
In a reciprocating power source supplying power in varying levels of potential throughout a given cycle, a method of converting reciprocating motion to rotary motion with uniform power output comprising the steps of: (a) providing an elongated endless rack supported by a base means and cooperating rotatable pinion assembly having a first pinion and a second pinion engaged to a pinion shaft; (b) securing to a common shaft a rotatable element; (c) positioning a cam follower means on said rotatable element for maintaining the pinion assembly in contact with a gear rack that meshes with the first pinion; (d) forming the end of the rack with a cam element; (e) securing to said base means a lock means that cooperates with said rotatable element for blocking rotation of said element; (f) contouring the surface of the cam element such that the cam follower means is operative to move the rotatable element to disable the lock means; (g) reciprocating the rack under control of said power source; (h) causing the first pinion to traverse the rack continuously as the rack reciprocates effective to rotate the first pinion continuously in a given direction; (i) using the first pinion to drive said second pinion; and (j) using the second pinion to drive a flywheel and an output shaft thereby rendering power output uniform throughout a given cycle.
Claim 11
Dependent Claim 224 words
