A program plate for a timer with setting means preferably arranged about the circumference of the program plate for the determination of a switching program, wherein the program plate is rotatably connected with a clockwork drive mechanism for operation of the program plate. An additional time display is operable through a further drive mechanism, which evidences a higher timewise resolution than the program plate, and which is integrated into the program plate. Within the circumferential surface area of the program plate, there is rotatably supported a preferably centrally positioned display disc for the higher resolved or defined time display, in which the further drive is supported within the program plate, and wherein the display disc is actuated by the further drive by means of the differential speed between the program plate and a housing component of the clockwork mechanism.

Program plate for a timer

An escapement or directional latching mechanism for a timer which actuates a timing switch component through the intermediary of a driving member, which is manually settable relative to the driving member against a larger moment of resistance in one direction of rotation as in the other direction of rotation. The escapement includes a ring having an internal toothing coupled with the driving member, and a ratchet wheel connected secured fixed against rotation with the timing switch component and which is located coaxially with the ring, with the ratchet wheel including at least two arms located in the plane of the ring, which with a finger thereof engage spring-elastically in the radial direction into the internal toothing, and which finger upon a displacement in one or the other direction of rotation is forced out of engagement with the internal toothing, whereby the pairing constituted of the internal toothing and the finger is provided with on the first pairing portion with tooth sides which are angularly symmetrical relative to the radius of the ring.
