Abstract
Abstract A control device for actuating an actuator for a predetermined period of time by the turning of a control knob to a selected time period and, thereafter, initiating the running of the time period by depressing a push button member, or for providing a continuous actuation of the actuator by setting the control knob in a continuous on manual position thereof, or for providing momentary manual actuation of the actuator by manually depressing the push button member when the control knob is set in its off position, the control device having a latch member which in one position thereof latches the timer motor from operating and in another position thereof unlatches the timer motor while latching a plunger operator for the actuator in its actuating position in both the time operated condition of the control device and the continuous on condition thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A control device comprising frame means, an actuator carried by said frame means, a movable plunger carried by said frame means to operatively engage and actuate said actuator when said plunger is moved from a first position thereof to a second position thereof, timer means carried by said frame means, latch mans including a movable latch member carried by said frame means, said latch member when in one position thereof operatively latching said timer means from operation thereof and when in another position thereof operatively unlatching said timer means and being adapted to latch said plunger in said second position thereof, and control means carried by said frame means, said control means having a first means for setting said timer at a preselected time period and having a second means for moving said plunger from said first position to said second position thereof.
Claim 2
Dependent Claim
143 words
A control device comprising frame means, an actuator carried by said frame means, a movable plunger carried by said frame means to operatively engage and actuate said actuator when said plunger is moved from a first position thereof to a second position thereof, timer means carried by said frame means, latch mans including a movable latch member carried by said frame means, said latch member when in one position thereof operatively latching said timer means from operation thereof and when in another position thereof operatively unlatching said timer means and being adapted to latch said plunger in said second position thereof, and control means carried by said frame means, said control means having a first means for setting said timer at a preselected time period and having a second means for moving said plunger from said first position to said second position thereof.
Claim 3
Dependent Claim
31 words
A control device as set forth in claim 1 wherein said plunger prevents said latch member from unlatching from said timer means when said plunger is in said first position thereof.
Claim 4
Dependent Claim
43 words
A control device as set forth in claim 1 wherein said second means of said control means can move said plunger from said first position thereof to said control position thereof independently of the position of said first means of said control means.
Claim 5
Dependent Claim
38 words
A control device As set forth in claim 1 wherein said first means includes a control shaft carried by said frame means and operatively interconnected to said first means of said control means and to said timer means.
Claim 6
Dependent Claim
39 words
A control device as set forth in claim 4 wherein said control shaft has actuator means for controlling movement of said latch member from said latching position for said timer means to said unlatching position for said timer means.
Claim 7
Dependent Claim
52 words
A control device as set forth in claim 5 wherein said control shaft must first move to at least one particular position thereof before said actuator means of said control shaft will permit said latch member to move to said other position thereof for latching said plunger in said second position thereof.
