Abstract:
A spring air gun includes a reciprocable piston and a slide for cocking the piston. The slide is movable between forward and rearward positions. A piston rod is connected to the slide and is slidably mounted within a piston tube which is connected to the piston. A pair of springs are concentrically mounted on the piston tube, and the forward end of each spring engages the piston. The rearward end of the inner spring engages the slide, and the rearward end of the outer spring engages the frame of the gun. A detent maintains the slide in the forward position, and a sear maintains the piston in the cocked position and is engageable with the detent for preventing the slide from moving rearwardly until the gun is fired. The gun is fired by pulling a trigger, which releases the sear from the piston. The detent can then be moved to allow the slide to be moved rearwardly to cock the piston. When the slide is not in the forward position, the detent prevents the trigger from being pulled.
Abstract:
A gun with a pivoting barrel includes a compression tube having a forked front end and a fork member which is inserted into the front end of the compression tube. The fork member includes a cylindrical body which is inserted into the compression tube and a pair of forked arms which extend along the inside of the forked end of the compression tube. A barrel is pivotably connected to the forked ends of the fork member and the compression tube. A spring clip on the barrel engages a stud on the fork member for releasably retaining the barrel in a firing position. A cocking lever connected to the barrel is engageable with a trigger extension for preventing the trigger from being pulled when the barrel is not in the firing position.
Abstract:
A light signal provides fixed focus and the ability to service the device solely from the rear. This light signal comprises a housing having a rear entry for desired maintenance and an immovable front wall, the lens mount containing a lens unit that is removable secured to an inside surface of the immovable front wall of the housing. Each lens mount includes a fixed focusing means having a receptacle for operative receipt of a light means, wherein the fixed focusing means is positioned at the end of the lens mount nearest an inner lens; whereby the focus of the light means is fixed relative to the lens unit.
Abstract:
A latch assembly configured to attach to a door includes one of a knob and a lever. The latch assembly further includes a latch extending from the door. A spindle is rotatable from a first position to a second position to move the latch from an extended position to a retracted position. A first biasing member is selectively operable to bias the spindle toward the first position. A second biasing member is selectively operable to bias the spindle toward the first position. An actuator is movable between a knob position in which only one of the first biasing member and the second biasing member biases the spindle toward the first position and a lever position in which both the first biasing member and the second biasing member cooperate to bias the spindle toward the first position.

Abstract:
A frequency generating circuit and a cap-freeing mechanism in a bolt are responsive to a longitudinal movement of a piston in response to overheating of an associated bearing. The cap-freeing mechanism transfers a force from the piston to a cap, thereby freeing the cap from a head portion of the bolt and allowing an antenna to extend to the outside of the bolt. The frequency generating circuit is activated by a connection made between a switch and a battery of the circuit by the piston. Upon becoming activated, the frequency generating circuit sends a predetermined frequency or frequency pattern through the antenna.
