Abstract
Abstract An actuator device for use with an interval timer comprises a manually displaceable setting member displaceable between a nonworking position and a working position and a locking lever for releasably locking the setting member in its working position whereby an output device may be actuated by the setting member when same is moved into its working position. The setting member is biased into its nonworking position by a biasing spring and is maintained in its working position against the restoring force of the biasing spring by the locking lever. The locking lever is mounted for pivotal movement into a locking position in response to manual depression of the setting member to thereby prevent return movement of the setting member and is mounted for tilting movement to an unlocking position in response to either further manual depression of the setting member or in response to movement of an external output member to thereby permit the setting member to return to the nonworking position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
An actuator device comprising: a manually movable setting member manually movable in one direction from a rest position to a set position and movable in the opposite direction from said set position to said rest position; biasing means biasing said setting member in said opposite direction towards said rest position; and locking means for releasably locking said setting member in said set position and operative in one mode in response to further manual movement of said setting member in said one direction to effect unlocking of said setting member thereby enabling said biasing means to return same to said rest position and operative in another mode independently of any further movement of said setting member in said one direction to effect unlocking of said setting member thereby enabling said biasing means to return same to said rest position.
Claim 2
Dependent Claim
138 words
An actuator device comprising: a manually movable setting member manually movable in one direction from a rest position to a set position and movable in the opposite direction from said set position to said rest position; biasing means biasing said setting member in said opposite direction towards said rest position; and locking means for releasably locking said setting member in said set position and operative in one mode in response to further manual movement of said setting member in said one direction to effect unlocking of said setting member thereby enabling said biasing means to return same to said rest position and operative in another mode independently of any further movement of said setting member in said one direction to effect unlocking of said setting member thereby enabling said biasing means to return same to said rest position.
Claim 3
Dependent Claim
108 words
An actuator device according to claim 1; wherein said locking means comprises a locking member, a movable locking lever, means mounting said locking lever for both pivotal movement into a locking position wherein same engages with said locking member in response to manual movement of said setting member into said set position and tilting movement into an unlocking position wherein same tilts out of engagement with said locking member, and means connecting said locking lever to said setting member to effect tilting movement of said locking lever in response to said further manual movement of said setting member in said one direction during said one mode of operation.
Claim 4
Dependent Claim
43 words
An actuator device according to claim 2; wherein said locking lever has a camming surface movable into camming contact with said locking member during manual movement of said setting member in said one direction to cam said locking lever into its locking position.
Claim 5
Dependent Claim
68 words
An actuator device according to claim 2; wherein said locking lever has an inclined surface movable into sliding engagement with said locking member in response to said further manual movEment of said setting member in said one direction and slidable over said locking member to tilt said locking member into its unlocked position by the biasing force of said biasing means when said setting member is manually released.
Claim 6
Dependent Claim
74 words
An actuator device according to claim 2; wherein said locking means includes an intermediate lever pivotally connected to said setting member and pivotal in a given direction in response to movement of said setting member in said one direction, and means mounting said locking lever for pivotal movement on said intermediate lever whereby pivotal movement of said intermediate lever in said given direction effects pivotal movement of said locking lever into its locking position.
Claim 7
Dependent Claim
19 words
An actuator device according to claim 2; wherein said locking member comprises a pin connected to said setting member.
Claim 8
Dependent Claim
64 words
An actuator device according to claim 2; wherein said locking means further includes another lever mounted for pivotal movement in a plane transverse to the plane of pivotal movement of said locking lever, and means on said another lever engageable with said locking lever to effect tilting of said locking lever into its unlocking position in response to pivotal movement of said another lever.
