ABSTRACT:
A motor operated swing or the like is disclosed which includes a canopy supported by legs which in turn has mounted therein a reciprocable closed carriage which supports a swing seat, cradle or the like and encloses the motor mechanism and the controls therefor. The canopy has outer enclosing end plates and inner end plates which are readily assembled to the canopy, with the inner end plates supporting a spring winding shaft with a spring tube thereon surrounded by the motor spring. A friction free escapement of synthetic plastic is provided which includes a toothed ratchet wheel, a gravity actuated safety pawl, a gravity actuated safety dog and a gravity actuated actuator for successively actuating said pawl and dog, the motor spring being connected at one end to the carriage and at the other end to the ratchet wheel. The escapement has double safety provisions for the pawl and dog, is constructed so as to be readily assembled without extra parts, and has accessible provisions for unwinding, if desired.
