' gaged by a cam follower at a position lying in *» * . . a second plane extending normal to said firs suriaoe at said position, and b, a second closed ourved surface facing in a direction opposite to said first surface and including: I first and second tracking sections disposed at different locations in a direction exten . A cam member for use in a cam-cam follower system for movement through a path lying in a first plane, said cam member having: a. a first curved surface adapted to be engaged by a cam follower at a position lying in a second plane extending normal to said first surface at said position; and b. i a second curved surface facing in the direction opposite to said first surface and including: first and second tracking sections disposed at different locations in a direction extending perpendicular to said first plane for engagement separately by two guide follower members disposed on opposite sides of said second plane, said two tracking sections being, contoured relative to the first surface for progressively directing said first surface through said position as the cam member is moved through said path relative to and between said cam follower and said guide follower members and for maintaining said first surface normal to said second plane as it passes through said position 5· A cam-cam follower system comprising: a. a cam having a first curved surface and a second curved surface facing in the direction opposite to said first surface and including first and second tracking sections; b. a cam follower engaging the first curved surface at a position lying in a predetermined plane extending normal to the first surface at said position; c. separate guide follower members engaging separately against the first and second tracking sections, said members being disposed on opposite sides of said predetermined plane and said two tracking sections being contoured relative to the first surface for progressively directing said first surface through said position as the cam member is moved relative to the cam follower and^guide. follower members for maintaining said first d. drive means for effecting movement of. the cam relative to and between 8aid cam follower and guide follower members* 6·> A cam-cam follower system according to Claim 5 further comprising: a* means for urging said follower members against said first or second tracking 1 sections in a direction to create a resultant force lying in said predetermined plane and extending through the position of engagement of the cam member with the cam follower 7* A cam-cam follower system according to Claim 6 wherein: < a* 8aid cam member is an annular structure with said first and second surfaces being closed curves; and b. said first curved surface of the cam member faces inwardly of the curve while the second surface faces outwardly* 8. A cam-cam follower system according to Claim 7 wherein: a*i said cam follower includes a rotatable wheel; and b. said drive means includes means for driving said wheel*' 9* A cam-cam follow)jer system according to Claim 8 wherein: a* said guide follower members comprise follower wheels rotatably mounted with their axes of rotation lying in one plane extending perpendicular to said predetermined plane* 10. A cam-cam follower system substantially as hereinbefore described) the with reference to accompanying drawings*' COHEN ZEDEK & SPISBACH P.O.BOX 33116, TEL AVIV., ATTORNEYS FOR APPLICANT
