<p>TITLE: PNEUMATICALLY OPERATED TOY EMPLOYING A MOVABLE IMPLEMENT An effective, relatively safe, relatively inexpensive toy can be constructed so as to utilize an air compressor to supply compressed air to move a piston within an output cylinder so as to in turn move an implement operatively connected to the piston. The piston is constructed so as to permit air to move past it in the event that the implement is for any reason reasonably restrained against movement so as to avoid possible damage to whatever is restraining the implement against movement and so as to avoid possible damage to the toy.</p> |
