Abstract: A pneumatically operated nail gun having a safety device which prevents a trigger lever from being accidentally manipulated. The gun has a nail guide movably disposed over a bit guide. A movable segment having a pipe-shaped portion and an arm portion formed integrally therewith is provided. The pipe-shaped portion is disposed movably in the nail guide, and the arm portion is movable in a slit of the nail guide. The arm portion is coupled to the safety arm whose end portion is engageable with the trigger lever. A spring is provided to urge the safety arm in a direction to maintain engagement between the end portion and the trigger lever. When the nail inserted in the nail guide is depressed onto the workpiece, the pipe-shaped portion moves against the biasing force of the spring, so that the end portion of the safety arm disengages from the trigger lever, whereupon the trigger lever can be operated.

Abstract: A device is disclosed for use in cutting specific lengths from the end of a shaft, specifically the shaft of a golf club. It includes a base that allows the user to affix the device to a table or support surface and a support block that can be rotated in relation to the table where the axis of rotation is parallel to and fixed in relation to the table. The support block has a calibrated stop rod, a handle to facilitate the rotation, a shaft or workpiece cradle, and a cutting slot that extends through the cradle in the support block. The calibrated stop rod is held in the desired position by a threaded rod being turned and thus urged against it when the desired cutting length is indicated by calibrating marks or indicia thereon. The shaft is then placed in the cradle and the device is rotated such that a cutting blade moves through the cutting slot, severing the shaft at the desired point.

Abstract: A hand tool having a pair of pivotally connected blades connected to a cutting blade having an arcuate outer edge with teeth thereon and an anvil so that on movement of the handles toward each other, the blade rotates toward the anvil and the anvil moves toward the blade to cut an object located between the blade and anvil.

Abstract: In the course of the upward turning movement of the magazine, the lowermost sheet of staples is taken from the staple cartridge as the feeding member is slidably displaced in the forward direction. Since the thrusting force given by the tension spring is sufficiently larger than the frictional resistance present between the lower surface of the lowermost sheet of staples and the feeding member, each sheet of staples can be more reliably taken from a staple cartridge. As the magazine is turned in an upward direction, a feeding member is displaced in the forward direction by the resilient force of a tension spring, and a contact portion on the feeding member comes in contact with the rear end of the lowermost sheet of staples.

Abstract: In a grinding mill, a polymeric filler material is molded into the rectangular or prismatic recesses in a metallic or ceramic lining. In a grinding mill where longitudinally extending elongate ribs of the lining have two different radial thicknesses or heights, with relatively narrow bars and relatively thick bars alternating with one another, the filler material is initially cast to have a cylindrical or undulating inner surface. Where the surface is cylindrical, the filler material is worn away during use of the grinding mill and gradually conforms to the alternating narrow and thick bars to assume an undulating inner surface. Supplemental lifter bars may be embedded in the grid and rubber filler material during the casting process. Where the lining is assembled from elongate wedge-shaped metallic or ceramic bas and spacers, the bars and spacers are provided in modular forms with the spacers as wing-like extensions on the bars. Ceramic or other hard particles are embedded in the filler material.
