y 5 1948- 1 F.- A. 'DODEZLIN 1 2,441,011 1 DISCHARGE HEAD FOR PRESSURE FL UID TANKS Filed Oct. 10, 1946 IN VEN TOR.
ZMQTM 7% ATTORN adapted to pierce the sealing disc at its center..
As the cutter. 26 isshifted axially, in the. manner to be explained, thepiri. 28 first pierces the sealing disc I1 and the shearing edge 21 then shears oii the disc at the inner edge of the shoulder [8. To prevent rotation of the cutter 25, as it slides within the chamber 23, a pin 29 is provided through the wall of the housing. This cooperates '4 provide a recess, as indicated at 54, at its upper end. This recess forms an extension of the explosion chamber within the piston. At its upper end the member 53 is provided with a laterally extending flange 55 which is normally held substantially in engagement with a. shoulder on the member 35. If desired theengagement of flange 55 with said shoulder may determine the upper limit of movement of the piston and a slight clearance may be provided between flange 32 and the plate 35. In the operation of the device the flange 55 shifts freely within the chamber 37.
with an elongated slot 30 in the wall of the cutchambers 24 and 25 of the housing. The main I I body of the piston is adapted to fit the bore of the chamber 24, while the flange 32 is arranged to .slide along. the wallet the chamber 25. A spring33, which surrounds the piston within the chamber 25, 'acts'at its upper end against the flange 32 and at its lower end against a shoulder 34 oi the housing. This spring tends to keep the piston inits upper position as shown in the drawing. A flat annular plate 35 is provided across theupper end of .the housing member 22 and is arranged to be clamped against the latter by a cup-like'member. 33 which forms another part of the housing. As shown, the member 36 is provided with internal threads adapted to engage externalthreads at the upper end of member 22. An inwardly extending shoulder within the member 33. serves to clamp the disc 35 and provides achamber 31 which may be considered a part of the explosion chamber. The latter is also .form'ed in part by successively reduced portions 38 and 39 of the space within member 35.
At its. upper or outer end the member 36 is externally .threaded to receive internal threads on a cap 40 which serves to retain a plug 4| within the'upper end of member 36 and squeezes this. plug against a gasket or washer 42 which provides an eiiective seal at the upper end of the; explosion chamber. Plug 4| is preferably formed of hard rubber or som suitable plastic material having good dielectric properties and capable of withstandingtthe heat and pressure of the explosion to which the device is subjected. A downwardlyextending central portion 43 of the plug is adapted to frictionally receive the upper open end 44 of a suitable small cartridge. The latter contains a charge of gun powder or other suitable explosive 45 which is held in the shell by a paper; wador disc 46. Plug 41. has a further downward extension 41 which is embedded, in the powder charge 45. .A pair of long passages 48, extending through the plug M from its outer to itsinner end, serves to receive and retain the two legs of a U-shaped electrical. resistance wire 49, the opposite ends of which are connected to binding posts 50. As willbe understood, when it is desired to discharge the. contents of the tank to which the unit is attached, current from a suitable source will be passed through the wire 49 toignite or set-ofi the charge 45. For the purpose of sealing on theupp r ends of the passages 48,: a small disc or washer 5| is provided, this being held in'place by a screw 52. The disc 5|, may suitably be formed of rubber or other insulating. material capable of providing a good seal.
Within the: piston 3! is provided a centrally disposed member 53 which is largely hollow to Member 53, piston 3|, and cutter 26 are Preferably held together as a unitary assembly by means of ascrew-threaded portion at the upper end of the spike 2B. This screw-threaded portion of the spike engages threads within the member 53 so that the spike serves to clamp all of the parts together.
An annular space is provided within the piston 31 around the member 53. Within this space a Sylphon bellows 51, formed preferably of copper or bronze, or stainless steel, is provided, this having its upper end attached by welding, soldering, or the like to the under surface of the innor edge of the annular. plate 35. The other end of the Sylphon bellows is preferably clamped between the lower end of the member 53 and the bottom of the piston, in the manner shown. If desired, any other or additional means, such as soldering, welding, or the like, may be employed to retain the lower end of the bellows.
It will be apparent that as explosive charge 45 is ignited, in the manner explained, by the passage of an electrical current through the wire 49, the gasses developed by the explosion will force the piston 3| and all of the connected parts downwardly to puncture and shear the sealing disc I! and thus allow the fluid within the tank to flow upwardly through the interior of the cutter 2B, outwardly through an opening in the side wall of the cutter, and into a laterally extending outlet branch 58. The latter may be threaded, as shown at 59, to receive any suitable form of coupling to connect the housing with a hose line or tubing for the delivery of the fluid to the desired points of use.
The smoke and dirt generated upon the explosion of the charge 45 is retained within the explosion chamber and is definitely prevented from reaching the relatively sliding surfaces of flange 55 within this chamber.
the piston 3| and the housing 22 by means of the Sylphon bellows 51., This bellows also prevents overheating of the piston by preventing the transfer of heat, by convection, from the explosion gases directly to the inner wall of the piston. Moreover, most of the smoke and dirt generated upon the explosion will be confined to the pocket or chamber 54 within member 53 and the portions 38 and 39 of the main explosion chamber above the laterally extending flange 55. Of course, as thepiston. moves downwardly these gases will expand and follow the flange 55 downwardly. A small portion of the gases may pass around the outer edge of the flange 55 and may enter the pocket provided within the bellows. However, the relatively small amount'of the gases which will do this; will carry very little dirt or heat into the bellows 5'! so that the latter is quite efiectively shielded. The small amount of dirt which will lodge on the surfaces of the chamber 3'1 will not interfere seriously with the subsequent use of the device,,because of the relatively loose fit of the Therefore, it is not necessary to take the device apart and clean slow escape of gases from said explosion chamber,
and an elongatable sleevemember connected at one end with said housing and at its other end with said piston member for shielding the cooperating surfaces of said piston and housing against the gases resulting from explosion of said charge.
