Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 178 words
A timing device comprising: a. a single base member, said base member including first and second sections, disposed substantially normal to each other, b. a rotatable shaft extending through said first section, c. A cam stack having individual cams carried by said shaft, d. a housing carried by said first section and substantially surrounding said cam stack, e. a first constant speed drive means coupled to said shaft and carried by said housing, f. a cooperating fixed and movable electrical contact means carried by said housing, said movable electrical contact means responsive to said cam stack, g. a second constant speed drive means carried by said second section, h. a single cam carried by said second section and coupled to said second constant speed drive means, i. a snap-action switch means responsive to said single cam, j. electrical terminals electrically coupled to said fixed electrical contact means and said snap-action switch means, and k. bussing means providing a means to selectively electrically couple said electrical terminals of said snap-action switch means and said constant speed drive means together.
Claim 2
Dependent Claim 178 words
A timing device comprising: a. a single base member, said base member including first and second sections, disposed substantially normal to each other, b. a rotatable shaft extending through said first section, c. A cam stack having individual cams carried by said shaft, d. a housing carried by said first section and substantially surrounding said cam stack, e. a first constant speed drive means coupled to said shaft and carried by said housing, f. a cooperating fixed and movable electrical contact means carried by said housing, said movable electrical contact means responsive to said cam stack, g. a second constant speed drive means carried by said second section, h. a single cam carried by said second section and coupled to said second constant speed drive means, i. a snap-action switch means responsive to said single cam, j. electrical terminals electrically coupled to said fixed electrical contact means and said snap-action switch means, and k. bussing means providing a means to selectively electrically couple said electrical terminals of said snap-action switch means and said constant speed drive means together.
Claim 3
Dependent Claim 27 words
