Abstract: A slide hammer tool is particularly useful for replacing worn teeth of a trenching machine. The teeth are retained in chain links of the trenching machine by respective open keeper rings. The tool has a rod with stops proximate both ends. A hammer is slidable on the rod between the stops. On one rod end is a wedge with converging surfaces that match radial surfaces on the keeper rings. The other end of the rod has a concave surface that matches the keeper ring outer diameter. To remove the keeper ring from a worn tooth, the wedge converging surfaces are abutted against the keeper ring radial surfaces. The hammer is rapidly struck against the corresponding stop. The impact of the hammer on the stop is transmitted to the wedge converging surfaces and to the keeper ring radial surfaces. The impact is sufficient to cause the keeper ring opening to expand, and the keeper ring is pushed off the tooth.

Abstract: A hinge pin remover comprised of a pair of plier members, each having a jaw portion and a handle portion, wherein the plier members are pivotally connected. A circular indentation is formed in each of the jaw portions of the plier members that is configured to fit around the shaft of a hinge pin. An edge is formed in the circular indentations which can be interposed between the bottom of the head of the hinge pin and the top surface of a flange forming a channel for the hinge pin.

Abstract: The invention concerns an apparatus and a method for mechanically joining metal sheets, profiles and/or multi-sheet joints lying on top of each other, wherein joining tools are moved by power means towards the parts to be joined and a joint is made between the parts to be joined by the force effect of the joining tools. To make the joining tools easier to handle and widen the range of application for joints, it is proposed to reduce the reaction forces of the joining process by the fact that one joining tool applies the joining force to the joint at an exciting frequency which is above the characteristic frequency of the opposite joining tool, and the mounting of at least one joining tool is isolated from vibrations. The vibration isolation can also be arranged exclusively or in addition in the excited joining tool or the parts to be joined.

When the pin is being extracted, the force is transferred through the slotted bar to the bottom of the head.

Abstract: A combination hinge adjustment and pintle removal tool which has the ability to perform three functions in a single wrench-shaped hand tool. A first end of the tool includes a punch tip mounted orthogonal to the longitudinal axis of the tool, which is used to initially dislodge the hinge pintle from the hinge by driving the opposite side of the tool body with a hammer. The same end of the tool also includes a cupped indentation centered colinear with the longitudinal axis of the tool.

Abstract: A pneumatically-powered battering ram for striking objects quickly and effectively with an initial high striking velocity resulting in an increased peak force effective in breaking the target object. The battering ram includes an elongated hollow housing containing a mass to be propelled, preferably a piston, and a supply of compressed gas, preferably carbon dioxide disposed within the housing. A valve mechanism releases a portion of the compressed gas into a charge cavity located between the piston and the supply of compressed gas. A sear mechanism holds the piston in place against the pressure of the compressed gas in the charge cavity. When the battering ram is swung at an object such as a door, a trigger mechanism releases the sear mechanism which in turn releases the piston. The piston is then accelerated forward by the compressed gas charge. Consequently, as the ram reaches the door, so does the piston which is traveling at a much higher velocity than could be obtained solely by manual swinging.
