VALVE CONSTRUCTGN Application iedliugust 13, 1930. Serial No. 474,932.

l opened very quickly to its full capacity, by a slight movement oii an operating lever; second, to produce a valve adapted for being installed in a tank bottoni, and that is capable of draining the contents or' the tank coml pletely; thirc to supply a. valve of the foregoing character which requires no packings 'for any ot its movingI aarts, and which, nevertheless, will not permit of any leakage or discharge of fluid except through the passage provided and intended for that purpose; tov sini, y I'alve embodying the above characteristics and that has a discharge spigot bottle necks and similar restricted inlets of receiving vessels; and, ftli, to accomplish the v ti'ated in the accompanying drawings, re aresenting an embodiment of my invention that is intended primarily tor the dispensing of iiuids into containers tl at have restricted inlets, and in which 1xlligure l is a side elevation o'l my improved valve construction, in cooperative relation to a tank bottom, and its operating mechanism, most of the parts being shown in central longitudinal s felon; and, n

Figure 2 is an elevation of the above valve by itself, when revolved 90 degrees about its axis from the position shown in Fig. l.

Similar reference numerals refer to similar parts throughout both views.

ln such uses as the self-serving dispensing of fluids, it is highly desirable to provide Jfor discharging an accurately predetermined quantity oi' the huid. rl iis may be accomplished by providing a storage container oi the exact capacity desired, ii' there are accompanying means 'for completely draining its contents. The obvious way of accomplishing this is to install the discharge valve at the lowest part of the container, arranged in suoli a manner as to completely drain it. Such a valve should have facilities :tor allowing it to be opened to its full capacity very quickly for permitting its discharge outlet to be inserted into an oriice of a receiving container; and Vigor preventing any drip or i'iow of luid 55 through any other passage than the discharge` outlet. Packings are objectionable, since they require attention and may become a possible source ot leakage, and also because they introduce more orless rictional resistance to '6g the operation of the parts packed.

l'assing to a detailed description of the 'forni of my invention that l have selected Jlor illustrative purposes', l have indicated aportion of the bottom of a sheet metal tank at 5. TWhere the metal ot the tank is relatively thin, it is desirable to :re-enforce it around the discharge oriiice.V This niav be accomplished by means of a metallin ring (i, surrounding the orifice at the outside, and brazed or sweated onto the tank bottom as indicated at 7. The thus re-eniorced outlet ci the tank is tapped.

lily valve comprises a tubular body meinber 8, the upper end of which is exteriorly screw-threaded at 9 and screwed through the a5 tank oriiice. lt frequently is desirable to provide a liange l0 on the body member, for supporting the valve operating mechanism. Such mechanism may consist of a supporting washer ll through whichthe valve body @o extends, clamped between ring 6 and flange l0, with gaskets l2 and 13 res iectively therebetween. rlhis supportingwasher has an integral, or otherwiseattached, portion 14, serving as a bracket for he operating lever l5, 'the latter being pivotally attached thereto by pivot screw 1G. c y

The upperfend of body member 8 constitutes a cylindrical chamber i7, and the lower end constitutes nozzle portion i8 having a 90 discharO'e passage 'i9 therethrough communicating with the chamber. The diameter of this passage is considerably smaller' than that of the chamber, and it is normali i closed by a-ball'QO, within the chamber and seated upon 95 the margin surrounding the mouth ol' the passage. Since the airis of this valve isvertical, the ball will normally vbe retained against its seat by gravity, 'lf additional y seating `force for this valve is desired, a

tapered helical spring 21 may be provided, and a plug 22 is screwed-into the top of the body member to serve as the reaction base for the spring, and to retain the parts within chamber 17.

.Fluid Yfrom the tank is allowed to enter chamber 17 through an oriiice in its side wall. This lmay be in the formr of the -V-shaped notch z3, the base 2li of the notch being horizontal and flush with, or slightly below, the level oi' the tank bottom.

Surrounding nozzle 18, and longitudinally slidable thereon, is a tubular spigot V25. This has a lug 26 projecting from its side, adapted 'for being engaged by the cam-ended eX- tremity 27 lof lever 15. Angular movement of theA spigot is prevented, and its longitudinal movement is limited, by the provision of .a longitudinal slot 28 in its wall, and vby the insertion of a stop-screw 29 through Athis slot and tapped into the wall oiffnozzle 18.

lVithin the bore ot spigot 25, near its lower end, is a perforate partition or spider 30, and an axial rod 31 extends upwardly therefrom and terminates just short of ball 20,- when the spigot is in its lowermost position. Therefore a slight upward movement of the spigot will serve to unseat the ball, and allow the contents of the tank to be discharged through passage 19 of the nozzle and passage 32 of the spigot. The raisingof the spigot is accomplished by pulling down on the operating lever at its right hand end, as by a chain (not shown) depending from hole 33 in the lever. n

Obviously the dimensions of spigot Q5 may be made such that it may readily be inserted into asmall bottle neck, or other restricted passage of a receiving container. It will also be apparent that all of the discharge from the tank mustnecessarily pass through passage 32. These provisions prevent splashing or any other diverted iowof thefluid, and there will be no loss thereofl in delivery to a customer.

Having thus fully described my invention, I claim:

1. Valve construction comprising; a tubular body member adapted for being inserted through a tank bottomvand having a tubular nozzle extending downwardly therefrom; a valve within said body at the upper end of the nozzle, adapted to close the passage therethrough; a tubular spigot surrounding said nozzle and slidable thereon; and means eX- ternal to said body for moving saidspigot upwardly; said spigot being provided with an axial rod extending upwardly through the nozzle passage and normally terminating just short of said valve, adapted to unseat the valve when the spigot is raised.

2. The construction set forth in claim 1 in co-operation with a tank bottom through which thek body member is inserted, and

therewith.
