Abstract: A paper binding apparatus such as staplers in the form of a thin, compact device employing pre-formed U-shaped staples where the staples are pushed through the papers by pressure applied directly by a hand pressing one of the stapler bars. The stapler enables a reduction in size of the stapler's dimensions, in particular its width, so that its width would be determined only by the thickness of the magazine. The stapler is based on performing the "stapling operation" in two steps. Initially, the stapler is closed and the magazine is parallel to the direction of the moving driving mechanism. The second stage, the operational one is that at which the magazine becomes perpendicular to the direction of movement of the driving mechanism.

Abstract: A fluid-driven tool for mechanically driving a spring-grip fastener onto a shaft or rod, which fasteners are automatically insertable within the tool and may be positioned at a predetermined depth upon the shaft by means of a stroke-adjusting device.

Abstract: A lightweight fastener driving tool capable of being battery powered utilizes a low cost fastener driving ram or blade that is normally located in a nip defined between a motor driven flywheel and an idler wheel. Upon the actuation of a trigger operated timing circuit, a solenoid is energized. The solenoid controls a toggle mechanism to adjust the position of the idler wheel with respect to the flywheel so as to force the blade against the flywheel and thereby to close the nip for a sufficient amount of time to initiate the driving of the blade downwardly through the nip. The timing circuit deenergizes the solenoid prior to the time that the blade exits the nip but the toggle mechanism maintains the idler wheel against the blade such that the blade continues to be driven by the flywheel. When the top of the blade exits the nip, the idler wheel can move towards the flywheel and the toggle mechanism releases the idler wheel so that the nip is open.

Abstract: There is disclosed a surgical instrument for implanting in bodily tissue, wound staples each comprising two legs and a crown connecting the legs. The staples are moved in succession out of a magazine onto an anvil, to be deformed thereon by means of a driver. The driver is lowered from a position of rest towards the staple on the anvil, and is further moved to close the staple on the anvil by bending the staple theraround, and to insert the legs of the staple into the bodily tissue. For problem-free and symmmetrical deformation of the staple, a hold-down device is lowered onto the anvil and upon deformation of the staple thereon presses the crown of the staple onto the anvil and so prevents the staple from moving laterally during its deformation.

Abstract: An air-powered driving tool for returning the working piston to its driving position by way of an auxiliary piston and valve arrangement. After the fastener is driven, the auxiliary piston is operated to engage the working piston to move it to its driving position after which the auxiliary piston is moved to an inoperative position. A valve is operated to direct high-pressure air to the auxiliary piston to move it to a working piston engaging position and then the air is released to allow it to return to its inoperative position. Thus, there is no force opposing the working piston when the driving tool is operated to drive a fastener into a workpiece.
