摘要： A tool mounting construction which includes a tool holder having a pneumatic cylinder, a piston in said cylinder for mounting a tool, pressure regulating means in communication with the cylinder for maintaining the pressure in the cylinder substantially constant regardless of the forces applied to the tool holder to thereby cause the piston to press the tool against a workpiece with a substantially constant force, an elongated rod having a first end for bearing against an external surface remote from the workpiece, and a connection between the tool holder and a second end of the rod for effecting a connection therebetween to thereby apply a force on the tool holder from the bearing relationship between the rod and the external surface. The foregoing tool mounting construction is mounted in a kit with a plurality of tubular extension rods for varying the length of the rod. The kit also contains a chest pad and associated coupling members which permit a workman to bear against the tool mounting construction with his body weight rather than applying the force thereto by sheer arm strength. A tool having pneumatic or mechanical mechanism integral therewith for causing the tool to apply a predetermined force on a work surface regardless of the external force applied to the tool. A tool mounting construction for moving a tool in a perfectly linear direction and which is mounted on an extension rod which is aligned with the linear direction by a level associated therewith.

摘要： A power tool combination including a hammer drill, an adapter secured to the drill for attaching it to an elongated rod which bears on the floor, a pneumatic cylinder and piston unit mounted between the elongated rod and the drill for applying an uniform external force for moving the power drill into the ceiling, and a coupling member between the pneumatic piston and cylinder unit. The coupling member is rigid for transmitting axial forces therethrough under normal operating conditions but is capable of yielding to absorb abrupt shock forces in the event that the drill encounters an undesirable obstruction in the ceiling, the coupling member including structure for causing it to return to a normal rigid condition after the shock forces have been absorbed.

摘要： A hydraulic jack comprises a first and second piston mounted on the opposite ends of a hollow piston rod which extends through a partition in a cylinder, said rod having an intermediate floating piston mounted thereon for axial movement relative to the first and second pistons. A first chamber is defined between the first and intermediate pistons, and second and third chambers are provided are on opposite sides of the second piston. These three chambers are filled with hydraulic fluid. An actuating piston, preferably of the same diameter as the other three pistons, is disposed in spaced relation to the second piston and is subjected to pressure transmitted through the fluid present in the third chamber to extend the rod of the actuating piston and thus engage the work or load. A sequence valve is located within the hollow piston rod to control the flow of fluid between the chambers and is normally positioned to establish communication between the first and second chambers. The sequence valve is responsive to an external load encountered by the actuating piston rod to interrupt such communication and establish communication between the second and third chambers whereby the pressure in the second and third chambers is intensified to a high-pressure sufficient to overcome the resistant force of the load encountered by the rod of the actuating piston. Air under pressure is employed to move the first piston and the sequence valve is operative to permit transfer of hydraulic fluid in a self contained supply from a low-pressure state to a highpressure stage through the hollow piston rod. Retraction of the actuating piston is also accomplished by compressed air and the hydraulic fluid is returned by means of the sequence valve to its original position.
