Application led June 29, 1905. Serial No. 267,507.

To (LZZ whom it may concern:

Be it known that I, ARTHUR KLEINFELDT, a citizen of the United States, residing at Hoboken, in the county of Hudson, in the State of New Jersey, have invented certain new and useful Improvements in Si hons for Dispensing Liquids, of which the fo owing is a specification, reference being had to the accom anying drawings, forming a part hereof.

T 's invention relates to apparatus of the general character of that shown in Letters Patent of the United States No. 706,423, dated August 5, 1902, and adapted for the supply of carbonio-acid gas or other gas under pressure to a liquid-containing receptacle for the purpose of dispensing the liquid under a uniform gas-pressure.

, The object of the invention is to improve the construction of such a paratus, and particularly to make it possib e to ll the liquidreceptacle while the receptacle containing the gas under pressure is in lace on the liquid-receptacle and is charged) with gas without occasioning the loss of gas, to provide for the automatic relief of excessive pressure in the liquid-receptacle without requiring the use of an independent safety-valve, and to prevent tampering with the apparatus after 1t has been regulated to give t e proper results under the conditions of use.

The invention will be more fully explained hereinafter with reference to the accompanying. drawings, in which it is illustrated, and 1n y xwhich- Figure 1 is a view of the improved apparatus in vertical central section, showing the receptacle.

gas dome or receiver and in art the liquid- Fi 2 is a detai view showing the controllingever in end view. Fig. 3 is a view of a portion of the apparatus shown in Fig. l, but with the tool or appliance inserted to open the valve in the ipe for the liquid. Fig. 4 is a view similar to 1g. 3, but showing a modification of the structure shown in Fig. 3 with parts broken oli.

` The gas receiver or dome or reservoir,

adapted 'to receive a charge of gas under con-'- siderable ressure, is mounted upon a cap or plug l), a ated to be secured tightly to the mouth of t e liquid-receptacle c. -The ca or plug b is rovided with a flanged outletji adapted to ave secured thereto a draw-off tap or valve f, which communicates, through a passage g, with a tube hwithin the liquidreceptacle c and extending nearly to the bottom thereof. Y

Arranged in the side of the gas receiver or dome a and adjacent to the operating-handle 7' of the draw-off tap is a plug or bushing 7c, provided with a thimble Z, having therein a passage which communicates with the interior of the dome or receiver a and with a'pipe m, through which the gas ma be admitted from the receiver into the liqui -receptacle c. The valve 'n is seated in the inner end of the bore of the thimble Z, its spindle o being provided at its outer end with a button or washer p,

which bears lagainst an elastic dia hragm g,

held againstthe end of the bushing by a cap r thereon. A spring s, surrounding the spindle o of the valve n and bearing against the washer p and a seat formed therefor in the thimble Z, holds the valve o normally against its seat with the button p pressed against the diaphragm g. A plun er t, bearing against the outer surface of t e diaphragm g or a block carried thereby and supportedbly the cap 1, extends outwardl through the atter in position to be engage b the cam-like end of the pivoted operatingever y', as clearly shown 1n Fi 1.

The liquioutlet gis closed normally by a valve-plug u, which preferably opens outward with the ressure of the llquid and gas in the receptac e c, as' shown in Flgs. 1 and 3,

so that it may act as a safety-valve to relieve excessive pressure in the receptacle c when lnecessary, being held to its seat by a spring o, which surrounds the stem u of the valve, bearing against the valveplug u and against a sealing-washerf, held in the casing of the tap f by a threaded nut f 2. The valve-stem u 1s rovided above the washer and nut with a for ed or slotted head u2, through which passes the operating-lever y', the head being provided with an adjusting-screw us, by

which the action of the lever y' in lifting the valve u may be regulated with respect'to its action u on the plunger t and the valve n.

As be observed bg reference to the drawings, the length of t e slot in the head u2 is considerablygreater than the width of the lever where it bears against the head, so

' thaty the ead is capable of movement inde- IOO pendently of the lever in the direction in which the valve u moves to open. As a convenient means for producing such movement of the head a2 and of the valve a independently of the movement of the lever for the purpose of moving the valve u from its seat without moving the operating-lever j, and therefore without opening the gas-valve n, a suitable tool or implement m may be provided, as shown in Fi 3, the same being adapted to be inserte between the upper Side of the lever j and the head a2 to lift the latter away from the lever j. ln order that the lever shall not be disturbed in this operation, it is preferably provided with two bearing-points, as at j and jz, on opposite sides of the fulcrum of the lever, one of such bearing oints, as y', being preferably slotted, as c early shown in Fig. 2, for the purpose of guiding and steadying the implement ai when it is being introduced. As shown, the implement consists of a convenientlyformed wire or rod, preferably having its end tapered, as at fc.

Obviously the valve u might be arranged to be opened downward against the pressure in the receptacle c, as shown in Fig. 4, the spring o in this -case acting lbetween a lower fixed abutment f3 and a shoulder at on the head u2 to hold the valve u normally up ward against its seat. In this case the eX cess of space between the lever and the head u2 is above the lever, so that when the implement is inserted, as shown in Fig. 4, beneath the lever j it forces the head downward in the proper direction to unseat the valve u, A Y

v As shown in Figs. l and 3 of the drawings, the adjusting-screw 'as is preferably covered by a key-cap f4, screwed on the body f of the tap, which furnishes a seat for the head of the screw to limit the movement of the lever and hence the extent of opening of the valves. The cap also conceals the head of the adjust, ing-screw, so that it cannot be tampered with by unauthorized persons who do not carry the key necessary to remove the cap `lf desired, ascrew-plug u4 might be inserted in a hole in the cap, so that by its removal access might be had to the adjusting-screw, which is otherwise concealed.

It will now be understood. that whenever it is desired to refill the receptacle c it can be accomplished even if the gas-reoeiver a is in place and is fully charged, for by the introuction of the implement a: the valve a is raised from its seat, as shown in Fig. 3, or is moved downward from its seat, as shown in Fig. 4, to o en the liquid-passage without disturbing tie valve n, With the valve u open and the valve a closed the filling of the receptacle c with liquid can be proceeded with in the usual manner. As soon as the implement a: is withdrawn the valves u and n are operated simultaneously by the lever y', so that gas from the receiver a is admitted to the receptacle c in proportion to the drawingoff of the liquid from such receptacle. If it be desired to provide the receptacle c with a l safety-valve, the construction shown in Figs.

l and 3 of the drawings is preferred, since the valve u, which is held normally to its seat by the spring v against the pressure from the receptacle c, is permitted to lift and relieve the pressure in the receptacle whenever such pressure becomes excessive.
