Abstract: A pressurization and regulating device uses a CO.sub.2 cartridge for pressurizing a fluid container such as the fuel tank of a gasoline lantern or stove, a garden or lawn sprayer, and the like. The device includes an elongated body having an open end for receiving the cartridge and a cap for forcing the cartridge toward the body. The other end of the body is provided with a fluid outlet opening. An outlet cap is mounted on the second end of the body. A piston is reciprocably mounted in the outlet opening of the body, and a seal on the piston is engageable with a valve seat in the outlet opening for closing the outlet opening. A spring in the outlet cap biases the piston away from the valve seat. An eccentric shaft is rotatably mounted in the outlet cap and engages the piston. The eccentric shaft is rotatable between a first position in which the seal engages the valve seat and a second position in which the spring moves the seal away from the valve seat.

Abstract: A cable guard includes a rod to be fixed to the handle of a compound bow extending from the handle toward the bowstring and positioned laterally offset from the central plane of the bow to keep the tension cables out of the path of an arrow fired by the bow. A tube fits slidably on the rod and carries a pair of pulleys at its distal end, coaxial with the rod and the tube. The first pulley is fixed to the tube, and the second pulley is freely rotatable on the tube. The tension cables are trained respectively into the grooves of the two pulleys on the side of the pulleys opposite from the central plane of the bow. As the bow is drawn the first cable turns its pulley together with the tube in one direction, while the second cable turns its pulley in the opposite direction. Simultaneously, the cables work together to draw the tube axially along the rod away from the handle.

Abstract: A modular construction for compound archery bows includes sets of spacer blocks for insertion between the bow handle and the limbs. The blocks are shaped to provide selected variations in the geometry of the bows, selectively adjusting the brace height and the overall length of the bow. The manufacturer is enabled to create bows of many different characteristics without investing in dies to produce differently shaped handles, needing only differently shaped spacer blocks.

Abstract: In a compound bow a pin is carried at one end of the tension cable and fitted through an axial hole in the eccentric wheel at the end of the flexible limb. A peripheral groove is formed in the pin at its end opposite from the cable, and the bowstring is looped around the pin, lying in the groove. The cable lies on one side of the wheel and the bowstring on the opposite side so that the pin is trapped in the hole in the wheel and no additional parts are required for retaining the pin in the wheel.
