Definitions

  • the present invention relates to a launching apparatus for discharging a projectile connected to a lifeline or the like, comprising a launching tube which is connected to a source of compressed air via a main valve having rapid valve movement.
  • a launching apparatus suitable for discharging a projectile connected to a lifeline or the like, comprising a launching tube connected to a source of compressed air via a main valve having a rapid valve movement.
  • a compressed air reservoir is arranged in connection with a launching tube.
  • the main valve is arranged between the reservoir and the launching tube and has a large flow area.
  • the valve is actuated into an open position by means of a pressure-driven servomechanism consisting of a cylinder with a piston which is connected to the main valve.
  • Inlets for compressed air to the cylinder space in back of the piston are provided, wherein a manually-operable valve in a non-actuated position holds said inlet open.
  • the manual actuated valve has a passage for draining air from the cylinder space in back of the piston which is open by operating the manual valve, while at the same time the inlet for compressed air to the cylinder space is closed, such that the pressure in back of the piston disappears and the piston is pushed back.
  • the front side of the piston being open towards the compressed air reservoir.
  • the valve means have however, an exposed position outside the compressed air reservoir and may easily be damaged. It also is necessary to arrange pipelines outside the launching apparatus.
  • the object of the present invention is to eliminate the above mentioned drawbacks, and achieve a compact launching apparatus and to protect valve means from damage.
  • a launching apparatus for discharging a projectile connected to a lifeline or the like, comprising a launching tube connected to a source of compressed air via a main valve having rapid valve movement, a compressed air reservoir being arranged in connection with the launching tube, the main valve being arranged between the reservoir and the launching tube and having a large flow area, the valve being actuated into an open position by means of a pressure-driven servomechanism consisting of a cylinder with a piston which is connected to the main valve, inlets for compressed air to the cylinder space in back of the piston being provided, wherein a manually-operable valve in a non-actuated position holds said inlet open, and a compression spring being provided on the back side of the piston which pushes the piston and thereby the main valve into a closed position, and wherein the manually-actuated valve has a passage for draining air from the cylinder space in back of the piston which passage is opened by operating the manual valve, while at the same time the inlet is
  • the figure shows a cross section through an embodiment of a launching apparatus according to the invention.
  • the launching apparatus consists of a preferably cylindrical, tube-shaped pressure chamber 1 which constitutes a reservoir for compressed air. At one end of the chamber, the forward end when the apparatus is in use, a launching tube 2 is connected to the reservoir via an annular flange 3.
  • the annular flange 3 has a passage 4 which corresponds to the passage 5 of the launching tube.
  • the flange 3 is formed with an inclined surface at the inner edge thereof which constitutes a valve seat 6.
  • a strong valve plate 7 having an inclined surface 6a corresponding to the valve seat 6 cooperates with the valve seat.
  • the valve plate 7 is attached to the forward end of a rod 9 which in turn is attached to a piston 10.
  • the piston is movable back and forth in a cylinder 8.
  • the piston 10 is controlled by a steering member 11 which runs in a bore 12.
  • the cylinder 8 is integrated into a holder 13 which by means of spokes 14 is attached to the interior of the reservoir 1.
  • a manually operable valve 15 is arranged in one of the spokes.
  • an inlet 17 for compressed air is arranged, as well as an outlet 18 to the cylinder space 19 in back of the piston 10.
  • an air drain passage 21 is provided in the valve slide 20 .
  • the slide 20 is extended such that it constitutes an actuating button 22.
  • the reservoir 1 is supplied with compressed air through a nipple 23.
  • the compressed air can be supplied, for example, from a compressed air bottle having a reducing valve such that the air supplied has a pressure of 60 kp.
  • the steering member 11 has an air drain passage 24 for the bore 12 when the piston 10 is pushed backwardly.
  • a compression spring 25 which serves as an auxiliary member for holding the valve 7 in place against the seat 6. This will be explained in greater detail below.
  • Fastened to the rearward end of the launching apparatus is a firing lever 26.
  • the firing lever 26 is made of a resilient material, for example a resilient plastic or plastic-coated steel, and in the unloaded state lies a short distance from the end of the actuating button 22. When the lever is pushed inwardly, it will press against the button 22 and the shot will be fired.
  • the purpose of the firing lever is to make the apparatus easier to operate, for example, with numb fingers or with mittens on.
  • the apparatus operates in the following manner:
  • the actuator button 22 will be provided with a safety guard to prevent accidental firing, for example, in the form of a cotter pin or a detachable cover.
