Abstract: A powered caulking apparatus includes a power source, a motor, a drive gear, an extension tape, and a top roller guide and bottom roller guide. The tape includes extension tape slots that receive gear teeth of the drive gear such that rotational motion of the drive gear translates into linear motion of the extension tape. The extension tape preferably comprises a radius, and the top roller guide and bottom roller guide preferably conform to the radius of the tape. The top roller guide and bottom roller guide may form an interference for the tape while still allowing linear motion of the tape. The apparatus may extend the tape to cause the tape to exert a force on a caulk tube to extrude caulk, and the tape may thereafter reverse linear motion of the tape to remove the force of the apparatus on the caulk tube.

Abstract: A projectile launching apparatus includes a linear motion converter driven by a motor, a piston coupled to the linear motion converter and reciprocally movable within a cylinder, a gas spring and a breech assembly. The piston, when actuated by the linear motion converter, may energize the gas spring, and after the gas spring is fully energized, the linear motion converter may release the piston. When the piston is released, the piston may compress a gas within the cylinder, which compressed gas may be communicated to a barrel of the breech assembly. The compressed gas may expand in the barrel of the breech assembly for launching a projectile that has been chambered in the barrel, with a high velocity.

Abstract: A fastener driving apparatus comprises at least one gas spring or spring, a drive mechanism, an anvil assembly, and an anvil. The drive mechanism selectively engages one of the at least one gas spring, spring or anvil assembly. A locking mechanism (such as a one-way clutch) is used to provide a middle stopping point during which the gas spring(s) is/are being energized. The motor of the apparatus may thereafter be turned off. When the user is ready to fire a nail, the motor is re-energized and the drive mechanism continues, releasing the gas spring(s) to drive the nail. The drive mechanism may include its own one-way clutch for overrunning and causing the drive mechanism to be released from the locking mechanism. To complete, the cycle the crank continues rotation and re-engages the anvil assembly and energizes the gas spring(s).

Abstract: A compact impacting apparatus includes a spring anvil assembly with a spring, an anvil, and a barrel cam. A cam follower engages the barrel cam to energize the spring anvil assembly. The spring anvil assembly is thereafter released to impact a striker, which striker delivers impact force to an impact target.

The spring anvil assembly may be disposed against a rotating pusher plate while engaged by the cam follower. Force of impact may be adjusted by repositioning the pusher plate and or changing the compression of the spring of the spring anvil assembly. The cam follower provides for repeated impacts upon the impact target and the striker holds the impact target in place for effective impacting.

Abstract: A fastener driving apparatus includes a spring anvil assembly that comprises a gas spring and an anvil. The end of the piston that extends out of the gas spring may be fixedly disposed against an object that is capable of exerting a force against the piston for at least a portion of the operational cycle. A drive mechanism acts on the spring assembly to store potential energy in the spring. The drive mechanism thereafter ceases acting on the spring assembly and the potential energy is released, causing the spring anvil assembly move and to separate from the drive mechanism for a period of free flight of the spring anvil assembly, the anvil thereafter moving to strike a fastener to drive the fastener into a substrate.
