Abstract A timer in a camera having a depressable camera release plate having a pivoted camera release lever that actuates a shutter release lever when the depressable release plate is depressed for taking exposures. The timer provides for timed exposures and comprises a governor which is manually charged. The governor has a gear that is driven when the governor is charged to actuate an interlocking lever transported on a self-release lever biased to a raised position in which the interlocking lever cams the camera release lever clear of the path of the shutter release lever as the release plate is depressed. The charging of the governor manually automatically sets the timer for a timed exposure and a locking lever actuated by the interlocking lever when at its raised position locks the governor. When the release plate is depressed the interlocking lever effects release of the governor and the movement of the governor causes the gear to move the self-release plate downwardly so that it actuates the shutter release lever.

A self-timer for a camera having a depressable release plate having a camera release lever pivoted thereon and a shutter release lever actuated by said release lever when the depressable plate is depressed, the self-timer comprising, a self-release plate actuatable longitudinally, an interlocking lever pivotally mounted on the self-release plate, a governor having a rotatable gear for charging the governor, means for rotating the gear to charge the governor, a braking lever actuated by said interlocking lever for releasably locking said governor and for unlocking the governor, said gear having means for initiating movement of said self-release plate for transporting the interlocking lever to a position for camming the camera release lever out of the path of the shutter release lever when the depressable release plate is depressed when the goverNor is cocked for timed exposures, said interlocking lever having means releasing the governor when said depressable release plate is depressed and said interlocking lever is in said position, said governor having means restoring the self-release plate to a rest position when released by said braking lever, and said selfrelease plate having means actuating the shutter release lever when said governor restores it to said rest position.
Claim 3
Dependent Claim
21 words
A self-timer for a camera according to claim 1, in which said governor comprises an anchor actuated by said braking lever.
Claim 4
Dependent Claim
51 words
A self-timer for a camera according to claim 1, in which said interlocking lever is disposed in a position clear of the camera release lever when the governor is not charged to allow the camera release lever to engage the shutter release lever when the camera depressable release plate is depressed.
