Definitions

  • a dual configuration cable cutter in which two blades independently operated by opposed piston members cut the cable at the same point, thus eliminating the possibility of the cable jamming in the hoist and causing severe damage.
  • FIG. 1 is a view in longitudinal section of a complete embodiment of the present invention, shown in the prefiring condition.
  • FIG. 2 is a view similar to FIG. 1 showing the condition of the apparatus following the firing of the cable-severing mechanism.
  • FIG. 3 is a fragmentary sectional view taken on line 3-3of FIG. 1 looking in the direction of the arrows.
  • FIG. 4 is a somewhat isometric view of the piston and cablecutting portion of the device.
  • FIGS. 1 and 2 indicates a cable-cutting device having a substantially cylindrical housing 11 provided with a wall 12 at one end thereof and an internally threaded port 13 at its opposite end.
  • a second internally threaded port 14 is cut into the sidewall 15 of the housing 10 adjacent the end wall 12.
  • the ports 13 and 14 are adapted to receive gas expansion driving means such as pressure cartridges 16 therein.
  • a pair of opposed piston members 17 are slidably received within the bore 18 of the housing 11.
  • Each of the pistons are provided with sealing rings 19 to prevent the escape of gases between the pistons and the walls of the bore 18 during firing.
  • the pistons are each provided with flat blades 20 which are cut out of the body of the pistons and which extend in the direction of the center of the housing 1].
  • An arcuate upstanding wall 21 at the cable end of the blades 20 serves as a guide for the blade during firing.
  • each of the blades 20 is provided with an opening 22 therein through which the cable 23 is threaded.
  • the edges of the openings 22 are beveled as indicated at 24 to provide knifelike cable-severing blades.
  • the pressure cartridges 16 When it IS necessary to sever the cable 23, the pressure cartridges 16 are fired by means of some remote electrical impulse (well known in the art and therefore not illustrated). Expanding gases within the chambers 29, 30 between the ends of the pistons 17 and the pressure cartridges 16 drive the pistons 17 toward each other thereby causing the knives 24 of the blades 20 to sever the cable 23. It will be noted that the cable 23 is severed along the plane between the blades 20 and that in the event one of the pistons I7 fails to move by reason of cartridge failure or the like, the opposite piston will perform the necessary blade-severing operation.
  • FIG. 2 The condition of the piston assembly following cable severing will be seen in FIG. 2 in which the shearpins 26 have been cut and the knives 24 brought into position where the opening 22 therebetween has been substantially closed.
  • a cable-severing device comprising an elongated housing transversely bored to receive the cable therethrough, a longitudinal bore in said housing, opposed pistons, slidably carried within the longitudinal bore, a flat blade member on each of the pistons extending outwardly thereof in the direction of the opposed piston and in overlapping relationship, a cablereceiving aperture in each of the blades, a cable-severing edge on each of the apertures and a pressure cartridge carried by the housing and in communication with each of the pistons to drive the pistons and their blades in the direction of the cable to sever the said cable.
  • a device in which one end of the longitudinal housing bore is closed by a wall, the opposite end of the bore is closed by the pressure cartridge and a bore is provided in the side of the housing in communication with the longitudinal bore adjacent the end wall to receive a second pressure cartridge.
  • a device in which the cutting edges of the blades move along substantially the same plane during the severing action.
