S AFETY VENTIN G ATTACHMENT.
Specification of Letters Patent.
Patented Nov. 17, 1908.
Application filed May 7 1907. Serial No. 372,428.
Be it known that -I, J ACOB (JOHN, a subject of the German Emperor, residing at 19 Ashchurch Grove, Shepherds Bush, in the county of London, England, have invented certain new and useful Improvements in .Safety Venting Attachments; and I do hereby declare the following to be a full, clear, and exact description of-the-invention, such as will enable others skilled in the art to which it appertaiins to make and use the same.
This invention relates-to safety devices for venting casks, cans and other vessels in such a way that the accidental explosion of their liquid contents, when of an inflammable nature, is efiiciently prevented.
The device is of the type in which a cylinder or a plurality of cylinders of wire if desired, by cylinders of perforated metal, are mounted in connection with the opening in the vessei, say, the bung hole in the case of a cask, in such a way that when the bung should become fired the fire will be unable to pass through the gauze or other cylinder and ignite the whole. of the liquid. With apparatus of this class as hitherto constructed it has been proposed to-provide-the screw cap or other device by means of which access is obtained to the bung hole, for filling and other purposes, with a fusible plug secured to its seat by means of soft solder, which plug on a rise in temperature is blown out of the cap or the like and prevents explosion. 'I have found thisexpedient objectionable in practice owing to-the uncertainty of temperature or. pressure necessary for releasing the plug, and owing to the possibility of the plug becoming damaged by an accidental blow or otherwise in the event, say, of a cask falling over.
According to a former invention of my own fOPWhl Ch I have obtained Letters Pat- January 8th, 1907, I
hole is open .if the liquid- .the beveled portion 7',
valve held on its seating by the force of gravity alone.
My present invention refers to a valve for automatically releasing the pressure when it reaches any given point and is applicable to all classes of venting devices of the character before mentioned. And in order that my said invention may be better understood I will proceed to describe the same with reference to'the drawings accompanying this specification, in which my invention is shown applied to two'forms of safety venting devices, located in the bung hole. or filling hole of a cask, tank or the like, and in which Figure l, is a vertical sectional view of one form, and Fig. 2, a like view of another form of my invention.
a shows, for example, gauze of suitable mesh; the .particular construction of the cylinder forming no material part of my invention. This cylinder is soldered or suitably fixed to the lower part of a tubular piece I). In the form of the device shown in Fig. 1, the tube is beveled to form a counter furnished with a boss or projection b and its bore is beveled at itsupper end to form a seat for the cap e as shown. Surrounding the 'tube b is another tube 0 provided with a screw threaded extension at its upper end to receive the cap, and also having its inner upper end beveled to receive the boss 6. The tube 0 is further provided with a flange d for attachment by screws, or other suitable means, to the wall of the vessel surroundin the bung hole and containing the infiamma le liquid.
6 is a cap which screws on to the outside of the tube 0. This cap 0 has a circular depression f countersunk a central hole g, extending from the bottom of the countersunk depression to the other side of the cap e in which is screwed or otherwise secured a valve seating u.
h is a guide piece fixed at the bottom of the seating u, the guide piece in this particular case assuming the form of a ring with a number of arms so that "ir or gas can pass up around the ring past the guide piece.
In the top of the cap 6 1s fitted a valve which comprises the valve proper 7' consisting in this case of a perforated hollow disk having and which disk is of sufiiciently small size to enable it to rest on the bottom of the depression f on the seating u.
This disk j has a packing ring 1' on its under in the middle thereof and a cylinder of wire side, as shown, in order to make a ti ht joint,
and a circular perforated upstan 'ng portion is into which a rod m provided with a ball n at the top, can be dropped, the hole being so shaped that the bal cannot drop through. When inserted through the upper perforation in the valve 7' the ball may be retained in position by means of a screw or other cap 1). The rod m passes through the .guide 71. and a. helical spring g is placed around the rod m, between the ide h and a nut or the like screwing on to t e end of the rod m.
The construction of the valve at Fig. 2 is similar to that shown at Fig. 1. but in this case an air hole 8 is shown which allows 'air' The action of the device will be readily understoodz' The spring 9 can be regulated to allow the valve to open at any predetermined ressure and when such pressure is reached in the vessel, the inflammable gases or the like open the valve and blow off until the pressure is automatically reduced. In the event of the gases firing, the fire can at the most only pass into the lnterior of the gauze tube a and will not in any event fire thebody of the liquid in the vessel. Owing to the way in which the valve is formed, in the event of one side of'the cap j being fixed by the cask or the like leaning against any obstruction or from any other cause, the valve is still enabled to rise on one side as shownclearly at Fig. 2.
What I claim and desire to secure by Letters Patent of the United States of America 1s:-
1. In a safety venting attachment for bungs, the combination of a tube 0 provided with an extension at its upper end, said tube adapted to enter the bung hole of a barrel and provided with,a beveled inner bore, a tube 5 in said tube 0; and provided with boss I) seating against the bevel in the tube 0, a wire gauze cylinder a, attached to said tube 1), a cap 6, fitting the extension onsaid.
tube 0, and provided with a depression f, and a central hole g, a valve seat at secured in said hole, and provided-with the guide piece soasei h, a valve j seated on said valve seat, a rod m passing through said guide piece, and into said valve, and provided with the ball 9% at its upper end, and a spring 9 surrounding the lower end of said rod, substantially as described.
2. In a safety venting attachment for bungs, the'combination of a tube cprovided with a screw threaded extension at its upper end adapted to receive a cap, and with a flan e adapted to secure the same to a barrel, the ore of said tube being beveled at its upper end, a tube 5, provided with boss I), seating against said bevel, and, also, having its bore beveled at its upper end, a wire gauze cylinder attached to said tube 7), and located inside said tube a, a screw threaded cap e fitting the said extension and provided with a depression f, the outer walls of which fit the said bevel in the upper end of the bore of said tube 5, said cap, also, provided with a screw threaded hole 9, a screw threaded valve seat u, fitted in said hole, a hollow valve disk j, seated in said depression f, and on said valve seat u, said valve provided with a hole through its lower wall, and said valve seat provided with a perforated guide It, a rod m provided with a ball n at its upper end,
passing throu h the lower wall of said valve 7 and said gui e piece, and a spring surrounding the lower end of said rod and resting at its upper end against said guide piece, substantially as descrlbed.
'3. In a safety venting attachment for bungs the combination of a tube provided with a screw. threaded extension, and a flange adapted to secure the same to a barrel. a cap fittlng said extension and provided with a depression, said cap, also, provided with a screw threaded hole, a. screw threaded valve seat, fitted in said hole, a hollow valve disk seated in said depression, and on said valve seat, said valve rovided with a hole throu h its lower wal and said valve seat provi ed with a perforated guide'k, a rod provided with a ball at its u per end, passing through the lower wall 0 said valve and said erforated guide, and a spring surroun ing the lower endof said rod and resting at its upper end against said guide, substantially as described. In testimon whereof, I afiix my signature, in presence 0 two witnesses.
