FOR STORING, PROTECTING, ANN DISPENSING LIQlIE'FiEED Application filed January 31, 1980. Serial No. 485,022. i
The present invention relates to equipment adapted to be installed on customers premises for storing and dispensing petroleum gas in liquid phase, such as propane, under pressure, but which changes to a gas or vapor phase when its pressure is reduced to a certain extent.
It is the practice to provide supplies of liquefied gas of this character for customers by what is generally known as the twodrum and one drum systems. The former includes a cabinet or housing located on the premises of the customer and containing two drums or cylinders suitable for storing and dispensing liquefied gas, only one of which is ordinarily drawn from at one time, the other being normally in reserve and to be drawn from when a drum becomes empty. When empty it is removed and another substantially filled is substituted. According to the one drum system a cabinet or housing containing one drum or cylinder suitable for the purpose, is provided on the customers premises, the supply of liquefied gas being replenished from time to time without removing the drum from the premises. The advantages of the one drum system are to be found in low investment requirements, economics in distribution and increased conven: ience to the customer. This periodic charging of the drum or cylinder on the premises or the customer is accomplished by the use of tank delivery trucks, and the transactions between the distributor and customer are very much'like those between the distributor equipment such as those devices for cooking,
heating and lighting, in that the customer may be billed from time to time for so much i of the product as he has used between calls by the service man. Thus the customer is not required to make a large outlay at various times as is the usual ractice where a completely filled substitute rum is furnished for one which been emptied by the cus-,
tomers use.
An important factor from an economical standpoint of the one drum system is low cost of assembly and installation of the equipment on the premises of the customer, and the expeditious periodical servicing of customers. The drums are usually weighed to determine the quantity of liquefied gas which has been used and suitable equipment for this purpose is disclosed in a plication for Letters Patent of Paul S. ndacott, filed July 27, 1929, Serial Number 381,503. It is one of the principal objects of the present invention to provide equipment which may be quickl assembled, and which when assembled acilitates the procedure of weighing the drums and inspection by the service men while covering their routes.
This is in part accomplished by supporting on the drums such accessorie as excess pressure release devices and pressure regulating and reducing valves for control of the egress of the gaseous vapor from the drums, instead of on or by the cabinets, and in part by the placing of these accessories well within the planes of the lateral walls of the drums, so that the cabinets may be placed or removed over the drums while the latter rest in upright position on their bases and without injury to vention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification and in which drawings:
Figure 1 is a view partly in elevation and partly in vertical section on the line 1- -1 of Figure 2 of customers equipment.
Figure 2 is a horizontal sectional view on the line 2--2 of Figure 1.
Figure 3 is a fragmentary section on sub stantially the line 33 of Figure 2 looking in the direction of the arrows.

In the drawings, A desi 'nates a cabinet or housing including a base f3, main bod part C carried by the base, and a cover D or the body art. i
In igures 1, 2 and 3, E is a drum, preferably cylindrical in shape, comprising a base portion F, main body portion or lateral wall G, and a top Wall H which bulges inwardly as shown in Figures 1 and 3 and is preferablyT welded to the wall G providing a cavit In Figures 4, 5 and 6, K is a modified form of drum having a main body portion or lat eral wall L provided with an integral outwardly bulging to wall M.
Suitable means are shown for controlling the egress of gaseous vapor from the drums and K and service conduit lines 0 associated with means N. Ingress of the liquefied gas at the drum may be had thru valve P.
In the examples shown, the cabinet A differs only slightly from what is shown in aplication for Letters Patent filed by Paul S.
ndacott, May 26 1928, Serial Number 280,- 745, on Customers apparatus for storin and dispensing liquid gas, in that the base has a reduced portion 7 laterally engagin the interior surface of main body part the latter being preferably cylindrical in shape and resting upon the wider portion 8 of the base. The body part C has a mouth 9 or open upper portion, normally closed by a cover D which may be moved so as to expose the interior cavit 11 of the cabinet. An opening 12 is provided in the main body part C, adjacent the mouth 9 for a purpose to be subsequently set forth. The upper portion 10 of the cover may be dome or cone-shaped so as to readily shed rain water.
The means N for controlling the egress of gaseous vapors from the drums may comprise outlet valve 15 and-a pressure reducing and regulating device 16 in communication with valve 15 as by fittings 17 the devices 16 having an outlet 18 in communication with the aforesaid service conduit line 0.
The service conduit line 0 comprises a rigid section 20 and a flexible section 21, the former extending into the cavity 11 as thru opening 12, and the latter having connection with the outlet 18 at the low pressure side of the pressure reducing and regulating device 16, as by a coupling 22. The sections 20'and 21 may be conveniently joined in fluid conducting relation by a union 23. Y
The valve P serves as suitable means for the introduction of the liquefied gas into the drum and this may be accomplished by the used by the customer, by lifting the drum from the base and the use of scales. To facilitate the weighing operation the heads H and M may have welded or otherwise secured at their centers screw threaded socket members 25 for the reception-of a hook, not shown in the drawings, more fully disclosed in application for etters Patent filed by me for liquid gas containers, October 8, 1929, Serial Number 398,239. a
The devices 15 and 16, and the valves P are preferably carried by the top walls of the drums so thatthey are within the plane of the lateral wall of their respective drum thus making it possible to assemble the drum on the base B and particularly the pressure reducing and regulating device 16 in place before the main body part C of the cabinet is slipped into place in embracing relation to the drum and its accessories, without liability of damaging the latter. After these parts have been assembled, the rigid section of the service conduit line may be connected to the pressure reducing and regulating device 16 by the flexible section 21 in a manner that when valve 15 is opened, the service conduit line is subjected to a considerably reduced pressure over that which normally exists in the drum.
The preferred arrangement is to dispose this flexible section 21 uppermost, that is, so that it will extend over the inlet valve P, the outlet valve 15, and the device 16, where it may be readily inspected by the service man each time he weighs the drum and its contents, or replenishes the supply of liquefied gas in the drum.
It is to be observed that the procedure in weighing may be accomplished without disturbing the rigid section 20 of the service conduit line, this section in practice being secured to some rigid object, such as the building containing the heating, cooking and/or lighting fixture to be supplied with gas from this equipment.
In the form shown in Figures 1, 2 and 3 the valves for inlet and egress of the petroleum product are mainly disposed in the cavity J and the mercury seal or other safetydevice 19 carried by the pressure reducing and regulating device 16 may rest upon the top wall H as shown more particularly in Figure 3 but it is to be understood that various other arrangements may be provided at the upper portion of the drum without departing from the spirit of the invention as defined in the appended claims. For instance, in Figures 4, 5 and 6, where there is no such cavity as is shown in Figures 1, 2 and 3, the mercury seal 19 or safety device may be supported ,on a
leg 19' shown more I claim: 1. Customers e uipment for dispensing an inflammable lique ed gas comprising, a portable drum for the liquefied gas under superatmospheric pressure, a pressure regulator particularly in Figure 6.
