An explosively operated tool includes a ram and an anvil. The ram (22) is driven towards the anvil (20) by ignition of a cartridge. A crusher sleeve is provided on the ram (22) such that, in the event the ram is driven towards the anvil (20) without a member or members therebetween, by an accidental discharge of the tool, the crusher sleeve (50) can deform to thereby absorb kinetic energy from the ram (22) and safely render the tool inoperative.

A power booster bushing (14) for obturating powder gases in a cartridge case (10) employed by power actuated tools used for connecting power cables. The power booster bushing (14) supports an explosive power cell (12) and is slidably positioned in the cartridge case (14) bore (27) and has a series of ribs (62) defined by grooves (60) engaging the cartridge case bore (27). The interface between the cartridge case bore (27) and the bushing (14) is sealed during detonation of the power cell by means of the circumferential ribs (62). The bushing (14) undergoes an "accordion effect" during detonation characterized by axial compression of the bushing (14) and resulting in the prevention of powder gas escape through the open breech end (24) of the cartridge case (10).

A fastener driving tool is capable of not only linearly driving but also rotationally fastening a fastener into a workpiece P. The fastener driving tool includes a housing 2, a nose portion 40 formed with an injection passage 40a through which a fastener 41 is driven, a magazine 4 accommodating fasteners 41 and supplying a fastener 41 to the nose portion 40, a push lever 5 movable relative to the housing 2 upon depression against the workpiece P, combustion chamber frames 12, 22 movable in the housing 2 in accordance with the movement of the push lever 5, and first and second cylinders 7, 8 fixed to the housing 2. First and second pistons 71, 81 are movably disposed in the first and second cylinders 7,8, respectively, and a bit 9 extends from the first piston 71. A rod 14 formed with a rack 14A extends from the second piston 72. The rack 14A is engageable with a motion conversion mechanism 6 for converting a linear motion of the rod 14 into rotational motion of the bit 9.

A tool for securing a connector on a conductor using an explosive charge includes a first tool member and a second tool member movably mounted on the first tool member. A breech chamber is defined in at least one of the first and second tool members. The breech chamber is adapted to receive the explosive charge. A breech opening is defined in at least one of the first and second tool members and communicates with the breech chamber. A drive member is provided. The tool is adapted to forcibly move the drive member responsive to an explosion of the explosive charge in the breech chamber. The second tool member is movable between a closed position, wherein the breech opening is closed, and an open position, wherein the breech opening is open to allow loading and unloading of the explosive charge into and from the breech chamber, by sliding the second tool member relative to the first tool member along a slide axis and additionally pivoting the second tool member relative to the first tool member about a pivot axis transverse to the slide axis.

Bei einem Handgerät zum Einschrauben von Schrauben oder ähnlichen Befestigungsmitteln wird vorgeschlagen, einer für sich gesehen bekannten, nach dem Kolbenprinzip arbeitenden und durch das Zünden einer Ladung eine axiale Druckwirkung erzeugenden Schießapparatur einen einem ersten Kolben (16) nachgeschalteten zweiten Drehkolben (19) vorzusehen, der in einer Verzahnung mit einem zugeordneten Führungsrohr (21) zwangsgeführt eine gleichzeitige Axial- und Drehbewegung durchführt und an dessen vorderem Teil eine Schraube so gehalten ist, daß diese in ein entsprechendes Gegenmaterial eingeschraubt werden kann.

摘要:
A fastener-driving tool includes a combustion power source (14) configured for driving a driver blade (46) linearly towards a workpiece, and an electrical power source (80) associated with the combustion power source for rotationally driving the driver blade upon completion of the linear travel, both power sources being disposed in the tool.
