24 Claims.
The present invention relates to apparatus for discharging fluid material such as liquid or dry powder, and, more particularly, to the type wherein a charge of burning substance is utilized for developing pressure medium adapted to expel the material from a container.
Accordingly, an object of the present invention is to provide discharge apparatus of the foregoing type which is an improvement over such apparatus heretofore known.
Another object is to provide such apparatus wherein the pressure medium is metered into the container at a predetermined rate to prevent exwhich can be readily cleaned and reloaded.
A further object is to provide such apparatus which is simple and economical in construction. Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to oneskilled in the art uponemployment of the invention in practice. 7
In accordance with the invention, the foregoing objects may be accomplished by providing apparatus comprising a container for storing the material havinga discharge outlet, a closure for the outlet adapted to unclose the outlet upon the attainment of a predetermined pressure within the container, a chamber for a charge of burning substance adapted to develop pressure medium, the chamber being constructed to withstand a much greater pressure than the container, and orifice means for establishing communication between the chamber and the container adapted to meter'pressure medium into the container at a predetermined rate.
In an illustrative embodiment of the invention, a strainer is provided between the chamber and the orifice means to prevent clogging thereof by products of combustion, and a frangible disc is provided for preventing material in the container from'entering the chamber by way of the orifice means. .A plurality oflatera1 ports associated 2 with the orifice means are utilized to introduc the pressure medium into the container to minimize recoil. I
In this embodiment, the chamber is provided by a two piece construction including a removably secured cover member which facilitates access to the chamber for cleaning and reloading. The strainer has clip means for securing the charge of burning substance thereto and for securing the strainer in the chamber in proper relation to the orifice m'eans.
A preferred embodiment of the invention has been chosen for purposes of illustration and description, and is shown in the accompanying drawing, forming a part of the specification, wherein:
Figure 1 is a fragmentary longitudinal sectional view of discharge apparatus in accordance with the present invention.
Figure 2 is a perspective view of the strainer and charge of burning substance assembly.
Referring to the drawing and more particularly to Figure 1 thereof, there is shown a container ID for storing material such as liquid or dry powder adapted for use as a fire extinguishing medium or the like. The container may be spherical in shape or may be generally cylindrical, in either case having substantially hemi-spherical ends as shown. The container is constructed of suitable metal to safely withstand an internal pressure of about 800 pounds per square inch.
The container Ill is formed with an outlet opening II at the lower end or bottom thereof, in which an outlet spud or nipple i2 is secured.- The nipple has an internal shoulder l4 definin -an outlet port, which port is sealed by murals secured against the shoulder by a shear ring 1'3 and a screw ring I6. The closure I5 a's illustrated may be a thinfrangible or rupturable disc dc.- signed to burst and unclose the outlet upon the attainment of a predetermined pressure within the container, for example, approximately 350 pounds per square inch.
Anelbow I! or other fitting for connecting the outlet of the nipple to the pipe (not shown) adapted to conduct the material in the container to its point of use is secured over the end of the nipple by a coupling ring l8. A strainer I9 is positioned in the elbow over the outlet of the nipple for preventing fragments of the closure l5 from being conducted into the pipe.
A chamber 20 for a charge of burning substance adapted to develop pressure medium is provided at the top or upper end of the container; and comprises a bottom or receptaclemembertl and a top or cover member 22 removably secured to the member 2 I.
The receptacle member 2| is generally cupshaped and is secured in an opening in the container. The member 2! has a lower portion 24 extending into the container and has an upper collar portion 25 extending outwardly of the container which has an internal screw thread and a shoulder 26. The bottom of the lower portion 24 is formed with a well 2'! at the interior which is surrounded at its upper end by a collar portion 29 having an annular groove 38 extending about the exterior thereof. The bottom of the lower portion 24 is further formed with a boss or projection 3| at the exterior which has a plurality of lateral apertures 32 connected for fluid flow communication to the well 21 by a bore 34 and has a wall 33 facing the bore.
A member 35 having a metering orifice 36 therein is screw threadedly secured in the well 21 for metering pressure medium from the chamber to the container, and a rupturable or frangible disc 31 is positioned on the bottom of the well to seal the upper end of the bore 34 and is held in place by the member 35.
The cover member 22 has a skirt portion 38 threaded on the exterior for cooperation with the threads of the collar portion 25 of the receptacle member 2|. A gasket 39 is positioned between the shoulder 26 and the lower end of the skirt portion 38 to provide a pressure tight seal between the members 2| and 2-2. The upper interior portion of the cover member is provided with charge igniting means 40 of any conventional design, but preferably, of the electrically actuated type.
A charge 4| of burning substance such as slow burning powder adapted to develop pressure is placed in the chamber over the well 21, and a strainer 42 is disposed between the charge and the well for preventing products of combustion of the charge from clogging the metering orifice 36.
As shown in Figure 2, the charge 4| and strainer 42 may comprise an assembly to facilitate loading thereof into the chamber 2|]. The strainer has spring clip elements 44 secured thereto for attaching the strainer to the charge, and has clips 45 on the under side for engaging the collar portion 29 surrounding the well 27. The clips 45 may have projections 46 at their ends for cooperating with the groove 30 to more securely lock the strainer over the well and thereby hold the charge in place within the chamber.
If desired, a conventional safety discharge fitting 49 containing a safety disc 50 may be connected to the container as shown. The safety disc is designed to burst at a pressure of about 750 pounds per square inch in the event such a pressure is established in the container by unusual circumstances.
The container ID is further provided with a conventional fitting having an opening for introducing the material into the container and having closure means 52 for sealing the opening.
The chamber 20 may also be protected against excessive pressure developed therein in the event orifice 36 is blocked or the disc 3'! fails to burst for some unforeseen reason. Such safety means may be advantageously provided by forming the chamber cover 22 with an opening 60 in the top thereof and lateral anti-recoil openings 6| communicating with the opening 60, and positioning a safety disc 62 across the opening 6|) which is held in place by a hollow plug 65 threaded to the 4 cover at the interior thereof. The disc 62- has the charge igniting means 40 mounted thereon and the interior of the hollow plug 65 serves as a chamber for the charge igniting means.
The charge 4| when ignited, is adapted to develop a gaseous pressure medium in the chamber 20 which normally has a maximum pressure of about 3300 pounds per square inch, the chamber being constructed to safely withstand such pressure. The pressure medium passes through the strainer 42, is metered through the orifice 36 causing the disc 3'! to burst, and is conducted through the bore 34, against the wall 33 and through the lateral apertures 32 to diffuse the medium and thereby prevent the medium from blasting through the fluid material in the container l0. As pressure builds up in the container to a value which the closure l5 cannot withstand, the closure 5 bursts to unclose the outlet and to allow the material in the container to be expelled through the elbow 1! into a pipe (not shown) adapted to be connected to the elbow. The orifice continues to meter pressure medium into the container at a desired rate to provide a substantially uniform pressure head above the material during its entire discharge. The value of the pressure head depends on the resistance to the flow of the discharged material through the pipe, and normally is less than 750 pounds per square inch, whereby the safety disc 50 will not burst during normal discharge. Preferably, the apparatus and the distributing pipe (not shown) are so designed that, under normal conditions of discharge, the pressure head is about 200 pounds per square inch after the closure |5 has been burst. By controlling the pressure through the orifice, the container may be constructed of relatively light metal to thereby make its design more economical. In the event the orifice should be locked whereby an excessive pressure may be developed in the chamber, the safety disc is adapted to burst and provide for discharge of the pressure medium through the safety vents.
From the foregoing description, it will be seen that the present invention provides novel discharge apparatus which is relatively light in weight, simple and economical in construction, and yet can withstand the rough usuage to which it may be subjected.
As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.
