Timer construction and clutch construction therefor or the like

Abstract

A timer construction having a timer motor and a selectable time period unit adapted to be interconnected to the timer motor of a clutch construction to drive the time period unit for a selected time period, the clutch unit including a first rotatable member driven by the timer motor and having a plurality of teeth arranged in a ring-like circular array and a second rotatable member being axially movable and having a plurality of teeth on the outer periphery thereof. The second member is operatively interconnected to the time period unit and is adapted to have some of its teeth mesh with at least some of the teeth of the first member to be driven thereby when the second member is axially moved into the circular array of teeth of the first member. Each tooth of the first member comprises a leg having one end secured to a flat face of the first member and having the other end thereof disposed in cantilever fashion, each leg having a tooth face that extends between the ends thereof, is substantially flat, faces at an angle to the axis of rotation of the first member and has an inner edge that is angled relative to such axis of rotation.
