Definitions

  • a specific improvement in the tool resides in the use of a minimum number of parts, thus providing a simple mechanism for permitting the tool to be fired.
  • FIGURE 1 illustrates a perspective view of a tool made according to the principles of the invention and showing a connector and conductors therein;
  • FIGURE 2 is a fragmentary, sectional view of the device of FIGURE 1 without the connector and conductors;
  • FIGURE 3 is a view similar to FIGURE 2, showing the tool after firing
  • FIGURES 46 illustrate the tool of FIGURE 1 in the pre-fired, firing and post-fired conditions (respectively).
  • a pair of conductors C and C are adapted to be disposed within a C- shaped connector body A, having a slidable wedge W designed to hold the connectors in place as described above.
  • the tool includes a body or frame member B, and a firing mechanism F.
  • the body member is comprised of a flat, planar member adapted to receive a connector body A, of the type disclosed in the above-mentioned copending application.
  • This planar member 10 is supported by a longitudinal rib 12, and has a post 14 at one end to restrain the conductor and connector during the crimping operation.
  • a second post 16 at the opposite end is adapted to receive the barrel of the firing member.
  • the post 14 has a pair of recessed portions 18 and 20 which permit the conductors C and C to be received therein.
  • Post 14 also has a lip 22 projecting toward the other post 16 which fits over the top of the connector body A when the connector and conductors are in place (see FIGURE 1).
  • the firing mechanism F (FIGURES 2, 3 and 5) includes a barrel 24 with external screw threads 26 which mate with screw threads 28 in an aperture 30 in the post 16.
  • the barrel 24 is longitudinally coaxial with the the wedge W.
  • the central section of the barrel 24 contains an opening 32 through which section 33 of a ram member 34 moves as well as retains ram member 34 therein.
  • the opening 32 is undercut at 36 to permit sliding motion of another section 38 of ram member 34.
  • An abutting surface 35 is located at the intersection of sections 32 and 38.
  • the opposite end of the opening is also undercut at 40, forming an abutment 41, to accept a shoulder 42 on the other end of the ram member.
  • the length (FIGURE 2) of the undercut 40 is greater than the length of the shoulder 42 to permit movement of ram member 34 so that it can slide in a direction away from the wedge W.
  • the abutment 41 limits longitudinal travel of ram member 34.
  • the barrel 24 is further recessed at 43 to define a chamber to permit an explosive shell 44 to be inserted therein.
  • the explosive shell is disclosed in my prior application, Serial No. 793,814, filed February 17, 1959 (now Patent No. 3,007,409), and includes a cylindrical member 46 sealed at one end 48, and having a plug 50 seated therein.
  • the plug 50 retains a powder charge 52 and also has a primer 54 on its outer surface.
  • a projection 56 on the inner end of section 38 operates to detonate the primer 54, thus igniting the powder charge 52.
  • the shell has a shoulder 58 which seats against one end of the barrel 24 to support it therein.
  • a cap 60 is threaded over the end of the barrel 24 and has a pin 62 in its inside surface which punctures the sealed end of the shell 44.
  • the outer surface of the barrel 24 may contain radially-extending ridges 64 to permit the operator to grasp the barrel more easily.
  • a ring 66 may be attached to the rib 12 to permit the operator to suspend the device from a peg or his belt when not in use.
  • the connector body A When it is desired to make an electrical connection, the connector body A is fitted on the planar member 10 with the lip 22 securing it therein. The conductors C and C are inserted in opposite arms of the connector with the wedge W inserted therebetween.
  • the barrel 24, with the ram member therein, is threaded into the post 16 and this provides an adjustable feature so that the edge of barrel 24 can be brought into engagement with wedge W.
  • a shell 44 is forced into the firing chamber in the barrel with the section 38 of the ram member projecting into the shell.
  • the shoulder 42 on the ram member is retained within the undercut 40 by the wedge W, while allowing rearward movement of the ram member.
  • a cap 60 is threaded onto the outer surface of the barrel 24 with the pin 62 puncturing the closed end of the shell.
  • the cap is then struck a sharp blow with a hammer or a pair of pliers, and the reaction from the blow causes ram member 34 to move toward the primer 54 with sufiicient force to cause detonation.
  • Ram member 34 drives the wedge W into the connector body A, thus tightly securing the conductors C and C' between the wedge W and the connector body A.
  • the cap 60 may be unthreaded from the barrel and the release of the cap and the pin 62 permits burnt gases to escape from the shell. This relaxes the shell and permits it to be removed rather easily.
  • the ram member may be moved rearwardly to drive the shell 44 partially out of the chamber, thus permitting easy access to it. The tool is then ready to make another connection.
  • a tool for making electrical connections comprising frame means having a stationary section against which one element of a connection assembly engages, a power unit on said frame means including a barrel member having a chamber for receiving an explosive means, means on said barrel member to maintain said explosive means within said chamber, a ram member movably mounted in said chamber having one end for engagement with another element of said connection assembly and another end for disposition within a hollow portion of said explosive means to define an enclosed chamber, said explosive means having detonating means for disposition adjacent said other end of said ram member, said other end of said ram member being reactively driven against said detonating means upon said power unit being struck a forceful blow to detonate said explosive means thereby forcefully driving said ram member outwardly relative to said barrel member to forcefully drive the other element into the one element.
  • a tool according to claim 1 wherein means are provided on said frame means and said power unit to permit said power unit to be adjustable relative thereto.
  • a frame having an area in which one of said members is to be disposed, a firing means on said frame for engaging the other of said members, said firing means having a cartridge-receiving chamber for receiving an explosive cartridge, a ram member movably disposed in said firing means and having one section for engaging the other of said members and another section disposed in said cartridge-receiving chamber, said other section being disposed within a hollow portion of said explosive cartridge and along therewith defining an enclosed chamber, means on said firing means for disposition adjacent the end of said explosive cartridge to maintain said enclosed chamber closed, and detonating means in said explosive cartridge for disposition adjacent said other section of said ram member, said other section of said ram member being reactively driven against said detonating means upon said firing means being struck a forceful low to detonate said explosive cartridge thereby driving said one section exteriorly of said firing means and drive said members into frictional engagement with each other.
  • An explosively-operated tool for performing useful work to drive one member relative to another member comprising a frame member for engagement with one of said members, firing means on said frame member including a chamber for receiving an explosive means, a ram member movably mounted in said firing means, said ram member having a first and second section, said first section for disposition in a hollow portion of said explosive means adjacent detonating means thereof, said second section engageable with another of said members, said first section being reactively driven against said detonating means upon said firing means being struck a forceful blow to detonate said explosive means thereby forcefully driving said ram member and driving one of said members relative to the other.
