  • Patent number: 6202636
    Abstract: The present invention is a pitching machine for use in batting and fielding practice for baseball and softball. The pitching machine of the present invention uses an expanding gas to propel a ball down a barrel toward the intended target. While the expanding gas could be created by a variety of means without departing from the scope of the present invention, including a piston, ignition of a combustible fuel, or a chemical reaction, the preferred embodiment of the present invention uses compressed air in a reservoir. The compressed air is held in a reservoir and released into the barrel behind the ball using a quick release valve. Spin is imparted on the ball by means of an engageable friction surface which forms a portion of the barrel, thereby allowing the pitching machine of the present invention to simulate any type of pitch. The barrel is able to rotate relative to the pitching machine to allow the engageable friction surface to contact the ball at any angle.

  • Patent number: 5184852
    Abstract: A rod casing for activating vertically arranged latch bolts, the casing and latch bolts arranged in an active stile of a door and engageable to a door frame. The rod casing provides a vertically slidable actuator cam engageable by both a lock/unlock actuator and a delatch or dogging actuator. The lock/unlock actuator and the delatch actuator are rotatably mounted upon a spindle piece which itself is rotatable by a user such as by a key-activated lock cylinder. The lock/unlock actuator when rotated slidingly abuts the actuator cam and drives the actuator cam vertically upward to cause unlatching of the latch bolts. The delatch actuator, upon rotation of the spindle piece in an opposite direction underlies the actuator cam and dogs the actuator cam in its vertically risen position. To deactivate the delatch actuator, the lock/unlock actuator can be rotated to interfere and displace the delatch actuator to release the actuator cam from the dogging position.
