Abstract
A toy timing device including an escapement-like mechanism regulating the movement of a movable portion toward a position on a housing toward which it is biased by the alternate slipping and sticking of parts of a rubber band extending over ribs on the movable portion as the rubber band parts move along a continuous surface on the housing.
Claims5
An escapement-like mechanism comprising:
- a first member including a wall having a continuous surface;
- a second member mounted on said first member to afford relative movement of said members between first and second relative positions, said second member including a projection which stays in closely spaced relationship along said surface during said relative movement;
- means for biasing said members toward said first relative position;
- and
- a length of elastic resilient material mounted on said second member in a position generally aligned in the direction of relative movement of the members, said length extending across and being unattached to the projection with part of the length of elastic material slightly compressed between the projection and said surface so that the elastic material will intermittently stick and slip against said surface to regulate movement of said members from said second position to said first position under the influence of said biasing means.
