Abstract: An apparatus for expelling baseballs or other game balls with a considerable backspin. In the usual case, where the game ball is shot out generally parallel to the ground, the ball trajectory starts out relatively straight due to the rather large expulsion force, and thereupon when the expulsion force is almost spent, the backspin takes over, and the game ball will suddenly rise above the ground. This simulates a real life baseball pitcher whose fast ball has a "live hop". The apparatus features a rotating flywheel with an upper guide chute, in which is disposed a rubber pad to provide a constriction of lesser dimension than the diameter of the game ball, so that the game ball when fed onto the flywheel is passed through the guide chute, for subsequent expulsion in a generally linear, e.g. horizontal, trajectory, but with subsequent upward movement due to the backspin which is caused by the game ball passing through the constriction.

Abstract: A siren having electronic components is mounted on a cycle-type pedal-powered handle-barred vehicle. The components are actuated by a remote momentary action push button switch mounted on the handlebar of the vehicle at a location away from the siren. A multi-part kit including brackets, bolts, nuts and analogous hardware is employed to mount the siren on and to tilt the siren relative to the vehicle. The kit permits a user the option of mounting the siren on either a bicycle, or a tricycle, or a low-slung children's tricycle.

Abstract: A rear steering three-wheeled toy vehicle includes a frame which is propelled by a pedal-driven front wheel assembly rotatably mounted on the leading end of the frame.A rear steering assembly having a pair of rear wheels is pivotally mounted at the trailing end of the frame for turning movement about an inclined pivot pin. Lever controls are operatively connected to the rear assembly for turning the same in requisite direction about the pivot axis. A stabilizing arrangement reinforces the pivot connection formed by the pivot pin intermediate the rear assembly and the frame. This arrangement includes a support member, opposite ends which are detachably connected to the frame and to one end of the pivot pin. The arrangement also includes a support rod, opposite ends of which are detachably connected to the rear assembly and to the opposite end of the pivot pin.
