Abstract
Abstract This disclosure pertains to novel means whereby a cam pauses momentarily with respect to a pivotally oscillating cam shaft upon which the cam is mounted. The cam is pivotally mounted on the cam shaft in operative relationship with a cam actuator secured to the cam shaft. A cam follower maintains the cam in a fixed position as the cam shaft and cam actuator pivot in one direction through a predetermined angle, the cam actuator ultimately contacting and impelling the cam in the same pivotal direction. Oscillation of the cam shaft in the opposite pivotal direction impells the cam in the same direction until the cam again becomes pivotally fixed by the cam follower.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
A time-delay cam assembly comprising a cam shaft, cam means pivotally mounted on said cam shaft, cam actuator means secured to said cam shaft, cam follower means reciprocated by said cam means, detent means operatively mounted on said cam follower means and interacting with said cam means, whereby said detent means maintains momentarily said cam means in a fixed position as said cam shaft and said cam actuator means pivot through a predetermined angle.
Claim 2
Dependent Claim
74 words
A time-delay cam assembly comprising a cam shaft, cam means pivotally mounted on said cam shaft, cam actuator means secured to said cam shaft, cam follower means reciprocated by said cam means, detent means operatively mounted on said cam follower means and interacting with said cam means, whereby said detent means maintains momentarily said cam means in a fixed position as said cam shaft and said cam actuator means pivot through a predetermined angle.
Claim 3
Dependent Claim
36 words
A time-delay cam assembly as defined in claim 1 wherein said detent means including a projection mounted on said cam follower means and an indentation on said cam means matching substantially the contour of said projection.
Claim 4
Dependent Claim
46 words
A time-delay cam assembly as defined in claim 1 wherein said detent means including a roller rotatably mounted on said cam follower means, said cam follower means continually impelled against said cam means, said cam means having an indentation matching substantially the contour of said roller.
Claim 5
Dependent Claim
41 words
A time-delay cam assembly as defined in claim 1 wherein said cam follower means is slidably mounted on said frame means and impelled toward said cam means, said cam means having an indentation matching substantially the contour of said detent means.
Claim 6
Dependent Claim
32 words
A time-delay cam assembly as defined in claim 1, wherein adjustment means mounted on said cam actuator means permits angular adjustment of said cam actuator means with respect to said cam shaft.
Claim 7
Dependent Claim
32 words
A time-delay cam assembly as defined in claim 1, wherein adjustment means mounted on said cam actuator means permits angular adjustment of said cam means with respect to said cam actuator means.
Claim 8
Dependent Claim
97 words
A time-delay cam assembly comprising a cam shaft, cam means pivotally mounted on said cam shaft, cam actuator means secured to a cam shaft, cam follower means operatively mounted for motion imparted by said cam means, said cam follower means continually impelled toward said cam means, detent means operatively mounted on said cam follower means, said cam means having an indentation matching substantially the interface contour of said cam follower means, whereby said detent means maintains momentarily said cam means in a fixed position as said cam shaft and cam actuator means pivot through a predetermined angle.
Claim 9
Dependent Claim
97 words
A time-delay cam assembly comprising a cam shaft, cam means pivotally mounted on said cam shaft, cam actuator means secured to a cam shaft, cam follower means operatively mounted for motion imparted by said cam means, said cam follower means continually impelled toward said cam means, detent means operatively mounted on said cam follower means, said cam means having an indentation matching substantially the interface contour of said cam follower means, whereby said detent means maintains momentarily said cam means in a fixed position as said cam shaft and cam actuator means pivot through a predetermined angle.
