ABSTRACT:
An improved power-actuated tool having means for preventing firing if the tool is not properly aligned with the work surface. The tool housing member includes a slidably mounted firing mechanism having cocking means extending forwardly into engagement with a sensing means mounted in the barrel member for relative axial movement therewith. A first member is attached to the barrel member. A second member is mounted within the first member for relative axial movement therewith and with respect to the barrel member, and includes a portion adapted to engage the sensing means. The second member must be moved rearwardly with respect to the first member whereby the sensing means is moved rearwardly with respect to the barrel member and engages the cocking means to move the firing mechanism into the cocked position. The tool may also include an extractor mechanism mounted on the breech end of the barrel and provided with a lip portion adapted to engage the head of a cartridge positioned in the cartridge chamber. The extractor mechanism also includes an elongated portion slidably mounted in the barrel member and extending into a barrel guide slot. The end of the elongated portion is adapted to be engaged by a barrel guide screw secured to the housing upon movement of the barrel member from the breech closed to breech open position. The movement of the barrel member relative to the housing serves to move the extractor mechanism rearwardly with respect to the cartridge chamber thereby withdrawing the cartridge from the cartridge chamber.
