Claim 10

The invention of claim 8 wherein each pair of said surfaces is oriented perpendicular to said second direction, and each opening further providing a clearance with respect to its associated drive member in the first direction.

Claim 11

The invention of claim 2 wehrein said first eccentric means comprises at least one eccentrically mounted drive member, and said support means includes openings each opening receiving an associated drive member, each opening having a pair of oppositely oriented surfaces for contacting said associated drive member.

Claim 12

The invention of claim 10 wherein each pair of said cam surfaces is oriented perpendicular to said first direction, and each opening further providing a clearance with respect to its associated drive member in the second direction.

Claim 13

The invention of claim 1 further comprising means for selectively rotating said first eccentric means while holding said second eccentric means fixed, and for selectively rotating said second eccentric means while holding the first eccentric means fixed, to selectively provide displacement of said support means in one of two different directions with respect to said chassis.

Claim 14

The invention of claim 12 wherein said rotating means comprises first and second arcuate gear racks operatively coupled to first and second gears secured to said first and second eccentric means respectively.

Claim 15

The invention of claim 13 wherein said rotating means further comprises means including a timer gear of the machine for controlling the motion of said first and second arcuate gear racks to hold one of them against rotation and to intermittently rotate the other.

Claim 16

The invention of claim 14 wherein said rotating means further comprises means for axially shifting said timer gear to hold said first arcuate gear rack fixed while rotating the second, or to hold the second arcuate gear rack fixed while intermittently rotating the first.

Claim 17

In combination: first and second shafts; first and second gears secured respectively to said first and second shafts; and means including an axially shiftable timer gear for selectively holding a first one of said gears against rotation while intermittently rotating the second, and for holding said second gear fixed while intermittently rotating said first gear.

Claim 18

In combination: first and second shafts; first and second gears secured respectively to said first and second shafts; and means including an axially shiftable timer gear for selectively holding a first one of said gears against rotation while intermittently rotating the second, and for holding said second gear fixed while intermittently rotating said first gear.

Claim 19

In combination: a first, stationary member; a second member displaceably mounted with respect to the first member; first and second eccentric assemblies each mounted for rotation about a respectively differeNt axis fixed with respect to the first member and operatively interconnecting said first and second members; and means for selectively rotating said first eccentric assembly while holding the second assembly fixed, and means for selectively rotating said second eccentric assembly while holding the first assembly fixed, to selectively provide displacement of said second member in one of two different directions with respect to the first member.

Claim 20

In combination: a first, stationary member; a second member displaceably mounted with respect to the first member; first and second eccentric assemblies each mounted for rotation about a respectively differeNt axis fixed with respect to the first member and operatively interconnecting said first and second members; and means for selectively rotating said first eccentric assembly while holding the second assembly fixed, and means for selectively rotating said second eccentric assembly while holding the first assembly fixed, to selectively provide displacement of said second member in one of two different directions with respect to the first member.

Claim 21

The combination as defined in claim 17 for providing relative movement between two members either in a first predetermined direction or in a different direction, said members having openings, wherein: said first eccentric assembly includes a pair of eccentrics each having its shaft journaled in one of said members and the eccentric portion confined in an opening in the other member, said openings each having one side extending in said first direction and engaging each said eccentric for producing movement in a direction generally perpendicular to said side when said eccentrics are rotated, said openings having clearance for said eccentrics in other directions; and said second eccentric assembly includes a thrid eccentric mounted to coact with said two members, said third eccentric being journaled in one of said members and being enclosed by an opening in the other member, said opening having opposed parallel sides extending in a different direction from said first direction to produce relative motion of said members in said first direction when said second eccentric assembly is rotated.

Claim 22

The combination as defined in claim 17, comprising: means for positively restraining rotation of the first eccentric assembly during operation of said means for rotating the second eccentric assembly; and means for positively restraining rotation of the second eccentric assembly during operation of said means for rotating the first eccentric assembly.
