Definitions

  • the present invention relates to a vibrating blade knife, and more particularly such a knife comprising a body and a blade mounted in said body.
  • Knives with vibrating blades are already known, intended in particular for opening shells, in which the vibrations of the blade are obtained by electromagnetic means.
  • the invention aims to provide such a vibrating blade knife with pneumatic drive.
  • the subject of the invention is a knife with a vibrating blade comprising a body and a blade mounted in said body, characterized in that the blade is integral with an anvil sliding in a cylinder in which is disposed a movable piston , an axial duct opening into the cylinder on one side of the piston and a vent opening into the cylinder on the other side of the piston, means being provided for supplying said axial duct with alternating air pressure.
  • the piston may consist of a simple ball, but it is preferably made of an elongated member having a substantially spherical surface at each of its ends.
  • the axial duct can be formed on one side or the other of the cylinder, but it is preferably formed in the anvil, the vent opening into the cylinder on the side opposite to the anvil.
  • the axial duct can then open, at its end opposite to the cylinder in the side wall of the anvil, an air supply duct opening into the wall of the cylinder on the same generator as the axial duct.
  • Elastic means can be provided to press the anvil in a position such that the ends of the axial duct and the air supply duct are not opposite, a pressure exerted on the blade against the action said elastic means being capable of bringing said ends opposite.
  • a pneumatic switch is produced in this way since, as long as no pressure is exerted on the blade, the ends of the conduits are not opposite and therefore does not occur. no vibration.
  • a pressure is exerted on the blade, for example when opening a shell, the blade is pushed in until the ends of the conduits come opposite, which causes the setting in motion of the piston and consequently the vibration of the blade.
  • a seal can also be mounted on the anvil, so as to provide the seal between the anvil and the cylinder when the anvil is in its position where said ends are opposite.
  • said means for supplying an alternating air pressure comprise a pressure chamber connected to said axial duct and closed by a vibrating membrane.
  • the same membrane means can supply air under alternating pressure to a plurality of knives according to the invention.
  • the knife shown in the drawing comprises a body 1 serving as a handle, in which a blade 2 is mounted.
  • a bore made in the body 1 and a jacket 3 form a cylinder 4 in which is disposed a piston 5 with a very slight play.
  • the play can be of the order of 5/100 to 1 / 10th of millimeter for a diameter of the piston of the order of 10 mm.
  • the piston 5 is constituted in the present case by an elongated member comprising a substantially spherical surface 5a at each of its ends. This member forms two radial bearing surfaces 5b making it possible to guide it in the cylinder, spaced apart by an area 5c of smaller diameter in order to limit friction.
  • One of the ends of the cylinder 4 is put into the open air by a vent 6 while the other end slidably receives an anvil 7 with which the blade 2 is secured.
  • a conduit 11 is formed in the anvil 7. This conduit has one of its ends 12 opening axially in the cylinder 4 and its other end 13 opening radially at the periphery of the anvil.
  • Another duct 14 is formed in the body and one of its ends 15 opens radially into the interior wall of the cylinder 4 on the same generator as the end 13 of the duct 11.
  • Guide means are provided to prevent rotation of the anvil 7 and secure by Consequently, the ends 13 of the conduit 11 and 15 of the conduit 14 are indeed on the same generator.
  • the other end 16 of the conduit 14 opens to the outside of the body 1 at a location where it can be connected by a flexible conduit 17, to means 18 making it possible to supply the conduit 14 with an alternative air pressure.
  • These means 18 comprise in the present case an electric motor 19 on the output shaft of which a connecting rod 20 is mounted by means of an eccentric 21.
  • the end of the connecting rod 20 is fixed to a membrane 22 delimiting with a flange 23 an air pressure chamber 24 into which the end of the duct 17 opposite the knife opens.
  • the rotation of the electric motor 19 consequently causes a vibration of the membrane 22 and therefore an alternating pressure in the chamber 24.
  • the resulting alternating pressure is transmitted via the duct 17 to the air supply duct 14, but does not cause any vibration as long as the anvil is in the position shown in the drawing, where the ends 13 and 15 respective conduits 11 and 14 are not opposite.
  • shocks of the piston 5 on the anvil 7 occur at the rate of the period of rotation of the engine 19, these shocks causing the desired vibration of the blade 2.
  • the event can be connected to a chamber where an alternating pressure prevails in phase opposition with the pressure in the chamber 24, which increases the speed of displacement of the piston.
