Abstract
Abstract A machine controller for connection to a repetitively linearly movable part on the machine to be controlled, which machine includes means for controlling its operation, comprising a rotatably mounted cam shaft having cams for selectively actuating each of the machine''s control means, and means coupled to said shaft and to the linearly moving machine part to translate linear machine movement into rotational movement. Spring means is operably coupled to the assembly biasing it to a normal at rest position corresponding to the start position of the machine being controlled.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
115 words
Apparatus for controlling operation of a machine having a linearly moving machine element, comprising: a support connected to a relatively stationary part of said machine; at least one actuating means journalled for rotation on said support for actuating control mechanism of said machine; a rotatable member coupled to said actuating means for rotation therewith; an elongate connecting member drivingly coupled to said rotatable member and having means thereon for connection to said linearly moving machine element; and biasing means coupled to said actuating means yieldably biasing the latter to a predetermined at rest position, whereby linear movement of said machine element and said connecting member is translated to rotational movement to rotate said actuating means.
Claim 2
Dependent Claim
115 words
Apparatus for controlling operation of a machine having a linearly moving machine element, comprising: a support connected to a relatively stationary part of said machine; at least one actuating means journalled for rotation on said support for actuating control mechanism of said machine; a rotatable member coupled to said actuating means for rotation therewith; an elongate connecting member drivingly coupled to said rotatable member and having means thereon for connection to said linearly moving machine element; and biasing means coupled to said actuating means yieldably biasing the latter to a predetermined at rest position, whereby linear movement of said machine element and said connecting member is translated to rotational movement to rotate said actuating means.
Claim 3
Dependent Claim
36 words
