US Patent:
4236344, Dec 2, 1980
Filed:
Dec 4, 1978
Appl. No.:
5/966166
Inventors:

Abstract:
A toy having a pivotable component in the form of a construction wheel loader having a shovel, the toy including a manually actuable handle cocking a spring coupled to a slidable member having a rack portion for operating the shovel. Movement of the slidable member during cocking of the handle simultaneously moves a coupler connected to a piston slidable axially within a stationary closed ended cylinder. The piston has a minute aperture in the face thereof with a larger aperture in the skirt thereof with the apertures being on opposite sides of the piston seal. A locking lever coacts with the coupler for retaining the parts in the powered position against the force of the spring. Manual release of the locking lever permits the spring to urge against the slidable member with the two apertures in the piston providing speed regulation during movement of the piston into the cylinder for moving the slidable member gradually.
