Abstract
Abstract A rotary-linear motion converter has a rotatable housing and a shaft within the housing offset from the rotary axis thereof and having a number of journal or cam discs eccentrically fixed on the shaft. The journal discs are rotatably positioned within corresponding openings in a corresponding number of slide members which are slidably mounted in the housing for reciprocatory movement so that rotation of the shaft causes the slide members to reciprocate and to rotate the housing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
59 words
In a mechanical movement as claimed in claim 1 wherein said housing shaft is fixed against rotation and said second shaft is rotated about its axis whereby said housing will be rotated about the housing shaft under the action of the discs rotating within said slide members which slide said housing and rotate about a moving center of rotation.
Claim 2
Dependent Claim
50 words
In a mechanical movement as claimed in claim 1 wherein said housing is fixed against rotation and said housing shaft is rotated whereby said second shaft will follow a planetary path while rotating at twice the speed of said housing shaft and said slide members will reciprocate within said housing.
Claim 3
Dependent Claim
61 words
In a mechanical movement as claimed in claim 3 with there being a piston on each end of a slide member and a cylinder receiving each piston, means operatively associated with each cylinder and piston for actuating said cylinder and piston in a cycle of an internal combustion engine whereby the reciprocating movement of said slide members rotates said housing shaft.
