The loader is provided with a bore into which a projectile is loaded, and the loader is movable to a firing position to align the bore with the barrel of the gun. A bolt on the gun is movable through the bore of the loader into the barrel to position the projectile in the barrel for firing.

Abstract: A heat exchanger assembly for an undercounter furnace includes first and second complementary, flanged sidewalls shaped to provide a fire chamber. Integral lower combustion air intake and upper exhaust flue are formed from the same sheet metal as the sidewalls. The width of the fire chamber is less than its height and length. A circulating fan is located behind the fire chamber and between the intake and flue ducts, taking room air from the rear of the casing and forcing it forwardly to sweep over both sidewalls and into the room to be heated. The heat exchanger is mounted to a removable chassis.

Abstract: A safety link assembly prevents discharge or firing of a gun unless the trigger is pulled. The assembly includes a hammer link pivotally connected to a link mounting member. The link mounting member is pivotally mounted on the same pivoting axis as the trigger, and a trigger-engaging portion on the link mounting member engages the trigger so that movement of the trigger pivots the link mounting member. The hammer of the gun is pivotally mounted on the gun for movement between cocked and fired positions. When the hammer is in its fired position, it is spaced from the firing mechanism of the gun. When the trigger is pulled, the link mounting member pivots with the trigger to move the safety link into position between the firing mechanism and the hammer so that when the trigger releases the hammer from its cocked position, the hammer will strike the safety link and force it against the firing mechanism to discharge the gun.

Abstract: A cup is provided adjacent the generator tube of a kerosene lantern for holding a measured amount of fuel. A wick is located in the cup for burning the fuel at a controlled rate. A foraminous housing extends around and above the wick to control the entrainment of air with the fuel from the wick during burning and to direct the resulting flame against the generator tube thereby preheating fuel in the generator tube to its vaporization temperature until the heat of combustion of fuel at the mantle causes the vaporization of fuel in the generator to be self-sustaining.

Abstract: The portable single burner campstove of this invention is characterized by compactness to conform to the space limitations of backpacking. The cooking unit assembly which can be mounted on top of a tank includes a reflector bowl, a burner within the reflector bowl and a grate. In addition, there is provided a burner box attached to the reflector bowl in communication with the burner. The burner box includes internal venturi means for carrying fuel from the tank into the burner box. In particular, there is provided a tube extending inwardly from the side of the burner box. The tube serves to entrain air with the fuel as the fuel is fed into the burner box. In addition, the burner box serves as a mixing chamber and distribution plenum for feeding a steady flow or an air/fuel mixture to the burner. The portable single burner campstove of the invention is characterized by high efficiency with minimum external dimensions.

Abstract: Fusible low-temperature alloy is used to secure a flanged sleeve to an adjusting stem which adjusts the tension on a spring-biased diaphragm which actuates a normally-closed valve. If a predetermined temperature is reached, the alloy melts, displacing the sleeve and removing the compressive force on the spring, thereby closing the valve.

Abstract: A handle assembly is provided for carrying a container such as a cooler. The assembly includes a bracket having a pair of spaced mounting members, a pin extending from each of the mounting members, and a handle having a member terminating in a pair of pin-receiving channels joined to a pair of spaced grip members. The assembly utilizes the pins for rotating or sliding the handle with respect to the bracket. The container can be carried by moving the handle from a resting position to a carrying position using one of two distinct modes of movement provided by the handle assembly.

Abstract: A hand-held tool includes a pair of oppositely-directed punch heads coupled to a pneumatic cylinder and piston rod unit by an expansion linkage. A finger-actuated lever on the tool operates a valve to supply compressed air to the cylinder and piston rod unit which actuates the linkage and drives the punch heads apart. Each punch head is provided with a tri-facial point for forming a detent in metal adjacent plastic. Part of the metal is torn at the detent and embedded in the plastic to couple the two elements together. When the lever is released, air is routed to reverse the action of the cylinder and piston rod unit.

Abstract: Two arms of an articulated linkage are pivotally connected together. The distal end of one arm is connected at a pivot point to the side of the vehicle body, and the distal end of the other arm is connected to a tailgate pivot screw located on a linkage plate attached to the tailgate. When the arms are extended, the tailgate is held in a horizontal open position. As the tailgate is raised to the closed position, the connecting pivot point of the arms is moved downward, and a projecting guide tab on the linkage plate gathers the articulated linkage. A lock lever pivoted on the side of the vehicle has a slot to snap over the tailgate pivot screw of the tailgate, and is locked with a wing nut on the screw.

Abstract: A tent structure includes a covering which has four upright triangular walls laid out in rectilinear relation to each other. A pair of transverse ridges are formed at the top of the tent covering. A rigid ridge pole assembly supports the covering along one of the ridges; and a flexible spreader bar assembly supports the covering along the other ridge. Four top/corner pieces of covering material are provided--one for each quadrant defined by the cross ridges. Each top/corner piece extends between adjacent ridge sections and between the inclined edges of adjacent ones of the triangular walls to complete the enclosure. The spreader bar assembly overlies and is carried by the rigid ridge pole assembly; and the tent covering is tensioned by lengthening upright support poles which support the rigid ridge pole assembly.

Abstract: An air terminal for a horizontal vent of a sealed combustion furnace includes a faceplate for mounting to an exterior vertical wall. A horizontal flue pipe extension, receiving the combustion products, is surrounded by an oval sleeve. Fresh air is communicated to the furnace through the space between the flue pipe and the sleeve. The outlet of the flue pipe is at least about 3/4 in. outside the faceplate. An enlarged fresh air intake opening exists about the flue pipe, and a pocket-shaped rain shield is located beneath the flue pipe extending upwardly and inwardly. A horizontal wind deflector vane is located beneath the flue pipe and extends across the width of the fresh air intake opening for directing incident wind downwardly along the wall. The terminal improves operation of the furnace under all wind conditions, whether the furnace is operating on pilot or main burner modes.

Abstract: A fuel control means is provided for supplying vaporized fuel to burners such as gasoline lanterns and camp stoves. The control means includes fuel and pressurized air conduits which extend from the fuel tank of the burner toward the burning means and which provide inlet and outlet orifices. Inlet orifice restricting means and outlet orifice restricting or cleaning means are movably mounted within the conduit, and a valve member is movably mounted within the conduit to open and close the fuel passage therethrough.
