Abstract
Abstract Upon insertion of a coin into a receiver of a timing mechanism, an actuator rotates a ratchet which in turn rotates a cam. The cam and a disc each have a tab extending therefrom. When the ratchet and cam are rotated, the tabs separate from each other providing a desired timing cycle and the cam is set to close electrical switches. When the timer is operative, the disc rotates causing its tab to engage the tab of the cam to rotate the cam and open the electrical switches.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
In a coin operated controller wherein insertion of at least one coin into a receiving means associated with a timing mechanism causes a motor drive means to drive cam means to open and close electrical switches associated therewith, an improvement characterized in a means providing extended cycles for said timing mechanism comprising: (a) a drive shaft, (b) at least one cam fixedly carried on said drive shaft and having a plurality of lobes providing a cam outer periphery and notches therein, (c) at least one electrical switch biased in an open position when engaging said outer periphery and biased in a closed position when engaging said notices, (d) a ratchet fixedly carried on said drive shaft and including teeth synchronized with said lobes, and actuator means engaging said ratchet and rotating same a predetermined amount upon an insertion of a coin in said receiving means, (e) a rotating means rotatably carried on said drive shaft and a gear carried on said rotating member and coupled to said motor drive means, and (f) a tab extending radially from a periphery of said rotating member and a cooperating tab extending from a face of said cam means near its periphery, insertion of a coin causing rotation of said ratchet and said cam means and displacing said tabs with respect to each other.
Claim 2
Dependent Claim
220 words
In a coin operated controller wherein insertion of at least one coin into a receiving means associated with a timing mechanism causes a motor drive means to drive cam means to open and close electrical switches associated therewith, an improvement characterized in a means providing extended cycles for said timing mechanism comprising: (a) a drive shaft, (b) at least one cam fixedly carried on said drive shaft and having a plurality of lobes providing a cam outer periphery and notches therein, (c) at least one electrical switch biased in an open position when engaging said outer periphery and biased in a closed position when engaging said notices, (d) a ratchet fixedly carried on said drive shaft and including teeth synchronized with said lobes, and actuator means engaging said ratchet and rotating same a predetermined amount upon an insertion of a coin in said receiving means, (e) a rotating means rotatably carried on said drive shaft and a gear carried on said rotating member and coupled to said motor drive means, and (f) a tab extending radially from a periphery of said rotating member and a cooperating tab extending from a face of said cam means near its periphery, insertion of a coin causing rotation of said ratchet and said cam means and displacing said tabs with respect to each other.
Claim 3
Dependent Claim
237 words
In a coin operated controller wherein insertion of at least one coin into a receiving means associated with a timing mechanism causes a motor drive means to drive cam means to open and close electrical switches associated therewith, an improvement characterized in a means providing extended cycles for said timing mechanism comprising: (a) a drive shaft, (b) at least one cam fixedly carried on said drive shaft and having a plurality of lobes providing a cam outer periphery and notches therein, (c) at least one electrical switch biased in an open position when engaging said outer periphery and biased in a closed position when engaging said notches, (d) a ratchet fixedly carried on said drive shaft and including teeth synchronized with said lobes, and actuator means engaging said ratchet and rotating same a predetermined amount upon an insertion of a coin in said receiving means, (e) a rotating member rotatably carried on said drive shaft and a gear carried on said rotating member and coupled to said motor drive means, and (f) a tab carried by said cam means and a tab carried by said rotating member, insertion of a coin causing rotation of said ratchet and said cam means and separating said tab of said cam means from said tab of said rotating member, and motor driven rotation of said rotating member causing its tab to engage said tab of said cam means and rotate same.
Claim 4
Dependent Claim
237 words
In a coin operated controller wherein insertion of at least one coin into a receiving means associated with a timing mechanism causes a motor drive means to drive cam means to open and close electrical switches associated therewith, an improvement characterized in a means providing extended cycles for said timing mechanism comprising: (a) a drive shaft, (b) at least one cam fixedly carried on said drive shaft and having a plurality of lobes providing a cam outer periphery and notches therein, (c) at least one electrical switch biased in an open position when engaging said outer periphery and biased in a closed position when engaging said notches, (d) a ratchet fixedly carried on said drive shaft and including teeth synchronized with said lobes, and actuator means engaging said ratchet and rotating same a predetermined amount upon an insertion of a coin in said receiving means, (e) a rotating member rotatably carried on said drive shaft and a gear carried on said rotating member and coupled to said motor drive means, and (f) a tab carried by said cam means and a tab carried by said rotating member, insertion of a coin causing rotation of said ratchet and said cam means and separating said tab of said cam means from said tab of said rotating member, and motor driven rotation of said rotating member causing its tab to engage said tab of said cam means and rotate same.
Claim 5
Dependent Claim
32 words
In a controller according to claim 2 wherein a tab extends radially from a periphery of said rotating member and a tab extends from a face of said cam near its periphery.
