Abstract: This invention relates to an attachment device for a pneumatic hammer tool used to remove a bolt or rod being held in a fixture. The low cost attachment device consists of an alignment sleeve and a tapered coil spring which aligns a driving bit of an air hammer to the bolt to be driven from the fixture and absorbs the shock of the impact during the driving operation. As the driving bit reaches the end of its travel, the addition of a spacer bar allows the driving operation to continue. A method for removal of the bolt is disclosed to facilitate the removal operation. This method relies on the contact of the alignment sleeve with the fixture and the compression of the spring to facilitate quick removal of the bolt. An application of this apparatus has been used to remove a spring attachment bolt on a truck trailer reducing the time for removal to 30 minutes from 3 to 4 hours.

Abstract: Attachment members (28) are used for securing insulation panels (30) to structural components (31). Each attachment member (28) includes a nail (29) which is driven by a setting tool into the structural component. A connecting region (26a) on a guide tube (25) of the setting tool generates a frictional force with a counter-connecting region of a hollow shaft (28b) in the attachment member when the nail (29 is driven. Via the generated frictional force, it is possible to check if the attachment member is properly connected after the setting tool drives the nail. The frictional force between the guide tube (25) and the inside surface of the hollow shaft is greater than the frictional force between the hollow shaft (28b) and the insulation panel (30).

Abstract: A railroad spike driving tool (30) is adapted to be inserted by its shank (22') for cooperation into hand-held hammer machines of the type comprising a machine housing (10) with a cylinder (11), in which a reciprocating drive piston (14) via a gas cushion in a working chamber (12) repeatedly drives a hammer piston (15) to impact on the shank (22') during spike driving. Forward sudden displacement of the shank (22') causes the hammer piston (15) to perform a forward blow in the void and come to rest. If the tool (30), as a result of the last impact and simultaneous sideward shifting of the machine, happens to hit against the rail, a safety spring (36), pre-stressed between a rearwardly facing shoulder (34) on the tool (30) and the machine housing (10), prevents the tool (30) from bouncing back into the machine and thus from being hit by said hammer blow in the void or from releasing a new blow. Possible injury to the operator is thereby avoided.

Abstract: A fastener applicator, for example for cable clips, uses the kinetic energy of a flywheel rotated by a prime mover, preferably a battery driven electric motor, to drive a striker for firing a fastener into a support. An actuator which strikes the striker may be a fixed projection on the flywheel or be an element on the flywheel movable relative to the flywheel by centrifugal force to project the actuator from an inoperative position to an operative position for striking the striker. The drive from the prime mover to the flywheel is through a clutch or releasable drive coupling which temporarily disconnects the drive when the actuator strikes the striker so that the kinetic energy at the flywheel alone drives the striker and the prime mover is protected from the impact. A micro-processor measures the rotational speed of the flywheel and stops the prime mover when a pre-determined speed for the necessary kinetic energy is achieved.

Abstract: An improved impact apparatus of the type in which an impact member delivers an impact to a work piece, an elongated guide confines the motion of the impact member to within a predetermined path, an input handle receives the input movement, and a speed multiplying mechanism transmits the input movement to the impact member. The input movement is received as an input force along an input axis causing the input handle to move at an input velocity. This input is transformed by the speed multiplying mechanism into an output force along an output axis, causing the impact member to move at an output velocity which is faster than the input velocity. For apparatus in which the speed multiplying mechanisms are not axially symmetric, thus having output axis laterally displaced from the input axis, the present invention provides improved positioning of the input and output axes along lines that pass near the center of gravity of the impact member, thus minimizing the unwanted torque on the moving parts.
