Abstract: A firearm has a hammer and a trigger. The trigger abuts the lower end of a safety, and one or more springs urge the hammer down and constantly bias the safety towards a safe range. The upper part of the safety has a gap, and a sear is mounted coaxially with the safety in alignment with the gap. When the hammer is down, a nose on the hammer extends into the gap while lugs on the hammer engage abutment surfaces of the safety and prevent the latter from moving to its safe range. Partial cocking of the hammer causes the lugs to release the safety which is thereupon urged into such range. In the safe range, shoulders on the safety located opposite the abutment surfaces can engage the lugs to hold the hammer in a half-cocked position with the hammer nose contacting the sear. Further cocking of the hammer causes the lugs to become disengaged from the shoulders and the nose to release the sear.

Abstract: A valve assembly for controlling the flow of fluid has a housing defining a valving chamber accommodating a transversely movable valve plate. A manually operated lever connected to the valve plate with a rod is operable to move the valve plate between open and closed positions. A resilient member mounted on the housing within the chamber surrounds the fluid outlet opening in the chamber. Rails secured to the housing cooperate with the valving member to hold the valving member in sealing engagement with the resilient member when the valving plate is in the closed position. The valving plate may be connected with a remotely located actuator lever mounted on a tubular member secured to the valve housing.
