Abstract: A firearm having a toggle and bolt assembly. The bolt is reciprocal and houses a firing pin connected to a driver which are spring biased by the recoil springs. The firing pin is independent of the bolt and is engaged by a trip and sear mechanism when the weapon is initially cocked. The recoil springs act also as firing pins but are taken out of the system when the gun is cocked. The toggle mechanism is biased toward a bolt closed position by a handle spring. The ejector and trigger are held in place by pins in blind bores to prevent ready conversion to automatic firing.

Abstract: A hesitation blowback toggle action weapon in which an under-center toggle employing interconnected toggle links recedes and redirects the recoil energy directed against the face of the bolt generated at the time of firing into the handle of the weapon, and in so doing either:1. Avoids the full auto sear as long as the trigger is pressured so that movement of the bolt and linkage of the weapon will continue until the ammunition of the magazine is spent, or2. Engages a semi automatic sear pivotally associated with the trigger of the weapon to lock the weapon in toggle collapsed position until the trigger is sequentially released to unseat sear from the trigger, and then again pressured to release the sear from the toggle mechanism, thus firing another single round.

Abstract: A yoke weight lifting yoke supported by a harness is disclosed having a body member and pivotable, adjustable arm supports for pivoting to a comfortable angle with respect to the user's arms and for adjusting the height of the arm support with respect to the body member to properly align on the user's arms to prevent obstruction of the movement of the user's arms during weight lifting exercises such as bicep curls and tricep extensions.

Abstract: Hand held rifles and pistols employing a novel bolt firing pin configuration and controls therefor which effectively absorb the effects of the shell explosive forces.

Abstract: A toggle action pistol employing improved bolt design and movement control to reduce recoil, facilitate loading and ejecting of the shells and to substantially reduce misfiring of the weapon.

Abstract: A gun employing improved bolt design and movement control to reduce recoil, facilitate loading and ejecting of the shells and employable with a floating firing pin.
