Camera self-timer

Claim 2

In combination with a camera including a shutter and a shutter control mechanism movable between an advance shutter release position actuating said shutter and a retracted position, a shutter release member movable between an advance and a retracted position, a spring-wound self-timer motor movable between a spring-wound advanced and a spring-unwound condition, means responsive to said motor being in at least a partially wound condition for releasably locking said shutter control mechanism against movement to a shutter release position, means responsive to the concurrent advance of said shutter release member and the unwound condition of said motor for releasing said shutter control mechanism to a shutter release position, means for releasably locking said shutter release upon advance thereof to said advanced position, and means responsive to the closing of said shutter for releasing said shutter release member for movement to its retracted position.

Claim 3

The combination of claim 1, including means for braking said motor, and means responsive to the retracted position of said shutter release member for locking said braking means in a motor-braking position.

Claim 4

The combination of claim 2 comprising a governor including an escape wheel rotatable with the unwinding of said timing motor, said braking means including means for restraining the rotation of said escape wheel.

Claim 5

The combination of claim 1, including first means for releasably locking said shutter mechanism in a cocked position, and means responsive to the unwinding of said motor for releasing said first shutter-locking means.

Claim 6

The combination of claim 4 including second means for releasably locking said shutter mechanism in a cocked position and means responsive to the advance of said shutter release member for releasing said second shutter-locking means.

Claim 7

The combination of claim 1, wherein said shutter release member comprises an axially slidable rod spring urged to a retracted position and including a first leg, and said shutter release member locking means includes a stop member spring urged into the path of said first leg and releasably locked in a position out of said path, and means responsive to the unwinding of said motor for releasing said stop member for movement into the path of said first leg.

Claim 8

The combination of claim 1, wherein said shutter release member includes a depressable rod spring urged to a raised position and having a projecting leg, said locking means comprises a pivoted lever including a first arm movable into and out of the path of said leg and said leg being in the path of said arm when said rod is in a raised position, spring means urging said lever to an advanced position with said arm registering with the path of said leg, means releasably locking said lever in a retracted position, and means responsive to the unwinding of said motor for releasing said lever locking means.

Claim 9

The combination of claim 7, including means responsive to the retraction of said lever for braking said motor.

Claim 10

In a camera including a shutter and a shutter control mechanism selectively adjustable to a preselected shutter open time and a bulb exposure control in which adjustment during the shutter open position from bulb exposure to a time-setting position effects the closing of said shutter, a self-timer spring-wound motor, a shutter release member movable between an advance and a retracted position, means responsive to the wound condition of said motor and the advance of said shutter control member for releasably locking said shutter control member in its advanced position, means responsive to the advance of said shutter control member and the unwound condition of said motor for actuating said shutter control mechanism to open said shutter, and means responsive to the closing of said shutter for releasing said shutter release member for return to its retracted condition whereby the advance of said shutter control member when said motor is wound and said shutter control mechanism is set to bulb effects the continued open condition of said shutter until said shutter control mechanism is switched from said bulb exposure setting.

Claim 11

In a camera including a shutter and a shutter control mechanism selectively adjustable to a preselected shutter open time and a bulb exposure control in which adjustment during the shutter open position from bulb exposure to a time-setting position effects the closing of said shutter, a self-timer spring-wound motor, a shutter release member movable between an advance and a retracted position, means responsive to the wound condition of said motor and the advance of said shutter control member for releasably locking said shutter control member in its advanced position, means responsive to the advance of said shutter control member and the unwound condition of said motor for actuating said shutter control mechanism to open said shutter, and means responsive to the closing of said shutter for releasing said shutter release member for return to its retracted condition whereby the advance of said shutter control member when said motor is wound and said shutter control mechanism is set to bulb effects the continued open condition of said shutter until said shutter control mechanism is switched from said bulb exposure setting.
