Abstract: In the caulking gun disclosed herein, the piston of a caulking cartridge is driven by axial movement of a exteriorly threaded tube which is, in turn, driven by a rotating ring gear which is interiorly threaded to mate with the tube. The threaded tube is longitudinally split so that it can collapse out of engagement with the threads on the ring gear. A tapered plug cooperates with an expandable bushing inside the tube so as to hold the tube in engagement with the threads in the ring gear when the plug is in a first postion but, when the plug is moved to a second position, the bushing allows the tube to collapse thereby releasing pressure from the piston and allowing quick retraction of the split tube to facilitate loading of a new caulking cartridge.

Abstract: A dispenser gun having a hollow tubular body member for receiving a cartridge of flowable material therein, and a removable cap member to maintain the cartridge within the body member so that a nozzle of the cartridge extends through an opening in the cap member. The body member includes a trigger mechanism for acting upon a cam retaining mechanism to disengage a cable into a released position to allow a spring biased pressure disc, which is connected to the cable, to act upon the cartridge to dispense or discharge the flowable material therefrom. In the non-discharging position, the cam retaining mechanism engages the cable in a locked position so that the cable prevents any forward movement of the pressure disc against the cartridge. The cartridge can be of either the disposable type or the reusable type, where a liquid impermeable insert bag can be inserted within the reusable type cartridge.

Abstract: This dripless automatic syringe for dispensing fluids has a barrel for containing the fluid, a nozzle for discharging the fluid, and a housing to which the barrel is attached. A piston rod in the housing carries a rigid sealed piston head in the barrel for pushing out the fluid. Behind the piston head a normally unflexed elastic disc in the housing. The disc flexes when the piston rod moves forwardly under a driving force. The disc unflexes to retract the piston rod and piston head slightly when the driving force stops to create a suction which draws fluid back into the nozzle and thereby prevents dripping. The disc has an integral nipple which frictionally grips the rod to hold it in place, when the driving force ceases. The nipple permits axial rearward movement of the piston rod by an externally applied force for filling the barrel with fluid.

Abstract: When using cartridges with delivery plungers, the afterflow of the cartridge content after the action on the piston has stopped, is annoying and undesirable. In a dispenser for such cartridges, which has a ram to act upon the piston as well as a mechanism for driving the ram forward, this drawback is eliminated by the action of at least one retrieval element which is frictionally guided on a ram. The retrieval element is movable longitudinally (distance s) relative to the dispenser body and by way of retrieval springs, engaging at the retrieval element, loadable through the forward drive mechanism. In this way, immediately after each completion of the forward drive of the ram, the ram is guided back and the cartridge plunger as well as the releasable connection between cartridge and dispenser is reduced with respect to stress. This construction has application to dispensers for a single cartridge as well as for double (two-component) cartridges.

The shaped body is pivoted on a shaft remote from the trigger pivot and is preferably formed with a recess providing a curved finger engaging portion adjacent the end of the curved contour opposite from the pivot and adapted for moving the shaped body about the pivot to displace the detent from one position to an adjacent position on the caulking gun handle.
