Buttner, July 15, 1940, for Valves for gas cylinders and the like, reference to which is hereby made. One of the objects of the present invention is 10 to provide a new and improved form of ?tting or valve assembly which constitutes a unitary structure that will contain a gas check valve, posi tive manual control means for opening it, a pres l—‘! of Fig. 5; Fig. 8 illustrates an improved manner by which a ?tting, such as those shown in Fig. '7 or Fig. 3 may be mounted upon the container in a new and improved manner including a guard for the ?tting, and Fig. 9 is an illustration of a pair of tanks as they are disposed with respect to each other to place the ?ttings conveniently for receiving a . , sure relief valve, means for connecting the cylin 15 service line. Throughout the speci?cation and drawings, der to a regulator or the like, a closure for said like parts are indicated by like characters and means, and means for positively locking the man ual control means against opening during the time that the cylinder or tank is in transit or in storage. A further object of the invention is to pro vide a ?tting, as outlined, which is capable of use with a container having a threaded opening of less than one and one-half inches. referring to the several ?gures in the drawings the metallic gas cylinder generally employed for 20 storing and transporting lique?ed petroleum gas is indicated by the numeral I. The bottom of the tank may be fashioned in any suitable man ner with an opening la in the top which may be closed in one of two days shown in Figs. 1 and A further object of the invention is to pro 25 8 of the drawings, respectively. Referring to Fig. 1, the opening Ia is'perma vide a ?tting, as outlined in the two preceding nently closed by a spud 2 which may include a objects, that provides a pressure relief area of flange 3 adapted to be welded as at 3a, or other .015 square inch or more for a container used wise secured to the cylinder body.

Fig. 2; In the embodiment illustrated in Fig. 4, the Fig. 4 is a section taken upon the line 4--4 of ?tting 6 comprises a valve body 6a which is 55 chambered as at 8 to communicate with a pas Fig. 2; tainer; 2,408,912 ~~ " ~" 3 sage 9 having a raised valve seat I9 at the upper Figures 2 and 4, the diaphragm protector spring end ‘thereof and extending into the chamber 8. l3 and a disk guide 14 which is screw threaded 3| holds the diaphragm in its raised position to leave the stem 28 of the check valve free to close. When the lever 39 is in the dotted line position it moves the eccentric 38 to force the stem 33 on the‘upper end. The disk is adapted to be held seated on the valve seat I 0 by a safety relief spring l5 which is received at the upper end in inwardly to press the diaphragm protector 30, whereby the end of the valve stem 28 is posi tively engaged and the check valve is forced a recess |5a upon the bottom of the body 5a with open. A valve disk II is held on a valve stem [2, re ceived through the opening 9 by a disk retainer l2 to adjust the tension upon the spring I 5 which is preserved by soft solder I9 when the pressure sage 39 by means of two inclined intersecting passages 40 and 4| drilled into the body 6a through the outlet 39 and compartment 23, re relief characteristics are established. A guide stop I6 is threaded into the chamber 8 to limit the outward movement of the disk guide l4 when the valve opens, and a restriction 9a at the bottom of the passage 9 serves to guide spectively, The passage 39 receives a plug 42 that is adapt ed to seat on the intermarginal edges of a ring gasket 43 to close the passage 39 and prevent escape of gas from the chamber 23. A chain 44 is anchored at one end around the neck of the plug the valve stem [2 at the lower end thereof so that between the guide 16 and the restriction 9a .. the stem [2 is held against tilting, The passage 9 in the embodiment illustrated in Fig. 4 for pur in swivelled relationship and to the valve body 60. at the other end on a chain screw 45 (Fig. poses of illustration has a diameter of .281" and is in communication with the interior of the tank 2).

A check valve chamber 23 is machined in the valve body 6a to communicate with the interior of the cylinder through an upwardly extending internally-threaded collar 24, for the chamber 23. The internal thread receives the nut 25 of. the check valve, such as a dill valve, to force the packing member of’ the check valve into tightly seated ‘relationship to the tapered walls of the ‘passage 21 that extend to the chamber 23 to the interior of the cylinder.

The outer end of the chamber 23 is ‘closed by a diaphragm 29 partially supported by a dia phragm protector 30 and a diaphragm protector spring 3| which is disposed around and held in Thus, it is impossible for the plug 42 to be threaded into place with the valve 28 held in open position by the lever-.35 without the oper ator knowing or being required to close the valve by lever 38 to prevent the escape of gas. Once the valve 28 is permitted to close, the valve 36 of necessity, because of flatness upon the face of the eccentric, must of necessity be so located that when the plug 42 is threaded into place the chain 44 naturally and conveniently extends over the valve 36 to prevent tampering therewith. Moreover, the plug 42 has to be removed before the lever 36 is moved to valve opening position, and when removed the plug 42 has been removed under such circumstances that a connection will have been made either to the ?lling rack in the bulk service station or to the usual regulator 41, shown in Fig. 9. Referring now to Fig. '7, a further and pre ferred embodiment of the invention is disclosed wherein in addition to the intersecting passages provided with a radially extending flange 32a 49 and. 4 l, providing increase of liquid to the con supporting in guided relationship a stem or ele tainer during ?lling operations, a dill valve 59 is ment-33 that rests upon the upper face of the 60 provided in a threaded passageway similar to the diaphragm 29.

In Fig. 6, a construction is shown which can be used with either of the embodiments illustrated in Figs. 3 and 7 in which the safety valve em ployed is a dill type valve rather than a safety valve H, or in lieu of substitution of valves, the safety valve shown in Fig. 6 could be used to supplement the safety valve H by locating it adjacent to the passage 2| in the stock of the valve body shown to be sufficient for this purpose in Figs. 4 and 2. The safety valve 53 shown in Fig. 6 is dis posed in the vertical passage 54 threaded at oppo site ends thereof, as at 55 and 55, the tapering seat 57 of the valve being disposed inwardly of the threading 55 where the valve packing 58 and the valve itself are held in place by a valve nut 59. In this particular embodiment the stem ?ll of the valve moves outwardly to open and is disposed inside of the tank where it cannot be tampered with. Opposing the outward move ment of the stem 59 is a compression spring 6! inserted through the threading 55 where it is held under an adjusted tension by an adjusting nut 62, the spring 6! augmenting the normal tendency of the valve 53 to close. Thus, a safety valve construction is provided which can be dis posed within narrow dimensions in the stock of the valve body to augment other Valves of dif its inner spring which is not shown and flows into the container, ?lling it to the desired point. The supply of gas is then cut off, the connec tion removed from the chamber 39, .the valve 25 closes and the plug 42 is put in place. While the plug 52 may be fastened in any way, it is preferable to fasten it by means of the chains shown. Thus it cannot be lost when it is re moved and the chains serve the additional pur 10 pose mentioned below. When the full container has been taken to the point of use, it is connected with a system leading to the place where the fuel is to be burned or the contents of the container otherwise used, 15 and this connection is made through the cham ber 39 after the removal of the plug 42. Since pressure from within the container normally closes the valve 25, it is necessary to open it before the contents can be discharged. Manual means to do this include the lever 36, and the cam or eccentric 38, the follower 33 and the protector 38. Ordinarily when the container is not in use and the plug 42 is in place as shown in Figures 1, 2 and 3, the chain extends across 25 the handle of the lever 36 and holds it down in the closed position. When a connection to a system where the fuel is to :be used has been made, the plug 1%2 has been removed and the chain 64 is no longer over the handle 36. There 30 fore, the handle can be moved, for example, from the full line position of Figures 2 and 4 to the ferent or like construction. dotted line positions of those ?gures.
