DEVICE FOR DRAWING EFFERV ESCENT LIQUIDS.

SPECIFICATIONfoz-mingpart of Letters Patent No. 660,331, dated October 23, 1900.

Application filed May 12, 1900- T0 at whom it may concern:

Be it known that I, JOHN NAGELDINGER, a citizen of the United States, residing in New York, borough of Manhattan, State of New York, have invented certain new and useful Improvements in Apparatus for Drawing Effervescent Liquids, of which the followingis a specification.

This invention relates to improvements in apparatus for drawing off liquids under pressure of carbonic-acid gas without the excessive foaming which occurs when the liquid is drawn off directly from thefountain, the ob ject of the invention being to provide an apparatus in which the manipulations of supplying the carbonated beverage from the fountain to a pressurerelieving chamber, the discharge of the excess of gas from said chamber, and the drawing off of the beverage are accomplished by simple and easilymanipulated devices; and the invention consists of an apparatus for drawing effervescent liquids, which comprises a pressure-relieving chamber, a socket for supporting said chamber, the socket being provided with a supplychannel, a pressure-relieving channel, and a discharge-channel, a valved supply-pipe connected with the supply-channel, a pressure: relieving valve, a spindle for operating said pressure-relieving valve, a. valvechamber inclosing said pressure-relieving valve and provided with a dischargetube extending upwardly into the pressure-relieving cham-' ber above the level of the carbonated liquid in the same, a liquid-discharge valve, a stationary handle on the socket of the pressurerelieving chamber, an auxiliary handle below the same for operating the pressure-relieving and liquid-discharge valves, and a lever for operating the supply-valve, as will be fully described hereinafter and pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side elevation of my improved apparatus for drawing efiervescent liquids.

Fig. 2 is a front elevation of the same. Fig. 3 is a horizontal section on line 3 3, Fig. 1. Fig. 4 is a vertical longitudinal section on line 4 4:, Fig. 2, drawn on a larger scale. Fig. 5 is a detail vertical section of the reliefvalve for discharging the surplus gas from the pressurenrelieving chamber, drawn ona Serial Nb. 16,410. the model.)

still larger scale. Fig. 6 is a vertical longitudinal section showing the gas-relief valve of the pressure-relievingcham ber in position for discharging the surplus gas from said chamber. Fig. 7 is a similarsection showing the gas -relief valve and liquid -discharge valve in open position for discharging the carbonated beverage from said pressure-relieving chamber. Figs. 8 and 9 are horizontal sections on line 8 8, Fig. 4, showing the supply-valve respectively in closed and open position, so as to interrupt or permit the supply of carbonated liquid from the fountain to the pressure-relieving chamber.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a pressure-relieving chamber, which is preferably made of glass of suitable thickness so as to resist the pressure of the effervescent liquid that is to be supplied to and drawn off from the same. The pressure-relieving chamber A is preferably made of a rounded shape at its upper closed part and provided with a cylindrical neck, which is supported in a socket A, the lower end of the neck resting on an elastic packing-ring a, that is seated in an annular recess in the bottom of the socket A. The lower end of the neck of the pressure-relieving chamber A is made thicker, so as to form a rim 0., which is engaged by a split annular screw-nut A that screws by its exterior screw-thread into the interiorlythreaded socket A, so as to hold the neck of the pressure-relieving chamber A tightly in connection with the elastic packing a.

The rear part of the socket A is connected by a valved supply-pipe B with the vessel or fountain containing the carbonated liquid under pressure. In the bottom of the socket A are arranged two vertical channels d and 01 the channel (1 communicating with the supplypipe B, while the central channel d communicates with a discharge-spout D, which is screwed into the front part of the socket A diametricallyin line with the supply-pipe D. The bottom of the socket A is provided at right angles with the supply-pipe B and the discharge-spout D with a horizontal stationary handle H, while at a point diametrically opposite thereto are arranged two lugs h h, which are connected by a pivot-link h with 7 eeossi the end of the second fulcrumed handle H, which is provided with a circular enlargement that extends around a cylindrical casing H which slides on the cylindrical neck A of the socket A. The circular enlargement of the lower handle H is fulcrumed by diametrical pivot-screws h to the casing H the handle H being located vertically below the stationary handle I-I, so that when the palm of the hand rests on the stationary handie the fingers can readily grasp the lower handle H, and thereby lift it in an upward direction toward the stationary handle H.

In the neck A of the socket A is guided a spindle E, which is screwed into the bottom of the casing H and is held in position therein by a jam-nut e. The upper end of the spindle E carries a valve E, which presses on a seat at the upper end of a tube Ehwhich is attached into the bottom of a cylindrical valve-chamber F, located in the neck of the pressure-relieving chamber A. The bottom of the valve-chamber F is provided at its under side with an elastic gasket F,that rests on a circular valve-seat f at the upper end of the central channel (1 of the socket A, while the upper tapering end of the valvechamber F is provided with a tube f which extends centrally through the pressure-relieving chamber above the level of the liquid in said chamber, the upper interiorly-threaded end of the valve-chamber being screwed onto the bottom portion of the same, as shown clearly in Fig. 5. The lower part of the spindle is made solid, while the upper part is made tubular by means of a central bore, the upper end of the spindle being provided below the valve E with several transverse holes 0, while the lower end of the bore is also provided with transverse holes 0, which communicate with the hollow space around the spindle and from there with a small gasrelief spout D, which is located below the liquid-discharge spout D, as shown in Fig. 4:.

The valve E is provided with several upwardlyrprojecting lugs e, that abut against the upper end of the valve-chamber F, so as to lift the valve-chamber when the spindle E is lifted by the handle H and produce thereby, first, the opening of the gas-relief valve and then the opening of the liquid-discharge valve F, as shown in Figs. 6 and 7. A helical springs is interposed between the bottom of the cylindrical casing H and a washer g, which is pressed against an interior shoulder g, an elastic packing being interposed between the washer g and shoulder g. The tension of the spring 3 holds the gas-relief valve, as well as the liquid discharge and supply valve, normally in a closed position when the lower handle H is not lifted. When the handle H is lifted, the casing H slides in upward direction on the neck A of the socket A, it being provided with a vertical recess g for clearing the auxiliary gas-discharge spout D, the lifting of the sliding casin g H? and spindle E producing successively shorter arm of an elbow-shaped lever H which is fulcrumed to a horizontal lug b of the valve-casing, the longer arm or handle of the elbow-shaped lever being arranged parallel with and on a level with the stationary handle H, as shown clearly in Figs. 1 and 3. The rear end of the supply-pipe B is coupled with a pipe leading to the fountain containing the carbonated liquid to be dispensed.

When the proper connection with the fountain is made, rnyimproved apparatus for disposing the eifervescent liquids is operated as follows: The tumbler or other vessel into which the carbonated beverage is to be discharged is held in the left hand, while the right hand is used for operating the apparatus. For this purpose the palm of the right hand is placed on the stationary handle H, so that the fingers can grasp the handle of the main supply-valve and move the same toward the station ary handle. This opens the supply-valve B against the tension of its spring, so that immediately a supply of carbonated liquid from the fountain is delivered through the connecting-channel in the valve-casing and the channel d in the socket A to the pressure-relieving chamber, in which the liquid rises to such a level until the equilibrium of pressure in the pressure-relieving chamber and the fountain is established. As soon as the pressure-relieving chamber is filled to this extent the handle H of the su p pl y-valve is released and the auxiliary handle H grasped by the fingers, so as to produce the lifting of the same. This produces the lifting of the cylindrical casing H on the neck of the socket A and the lifting of the spindle E against the tension of the spring 3, so that first the gas-relief valve at the upper end of the spindle is lifted away from its seat, as shown in Fig. 6, and thereby the connection between the space above the liquid in the pressure-relieving chamber, the hollow upper end of the spindle, the interior of the valve'ch amber, and the gasdischarge spout is obtained and an immediate discharge of the surplus gas in the pressurerelieving chamber is produced. By continuing the lifting of the auxiliary handle, valvecasing, and spindle the upwardly-projecting lugs at the upper end of the gas-relief valve abut'against the upper part of the valvechamber F and produce the lifting of the same, so that the liquid-discharge valve in the neck of the pressure-relieving chamber is moved away from its seat, and thereby a connection between the neck of the pressurerelieving chamber, the channel (Z and the discharge-spout D is established, so that the carbonated liquid can be drawn off from the pressure-relieving chamber withoutexcessive foaming into the glass or vessel held below the spout. During the drawing off of the carbonated liquid from the pressure-relieving chamber the air is permitted to pass through the auxiliary spout D, the neck of the socket A, the central bore of the spindle, valve-chamber, and the discharge-tube, so that atmospheric pressure is established in the upper part of the pressure relieving chamber and the free drawing off of the carbonated liquid into a tumbler or vessel obtained. The blowing off of the surplus gas through the auxiliary spout and the discharge of the carbonated liquid take place in quick succession, as the upward motion of the auxiliary handle produces the opening of the gas and liquid discharge valves, the escape of gas being indicated by a slight noise, which takes place immediately before the flow of the liquid from the dischargespout. When it is desired to interrupt the discharge of the efiervescent liquid, the auxiliary handle is released, so that the gas relief and discharge valves are immediately returned by the tension of the spring on the sliding casing H to their closed positions on the respective valve-seats and the discharge of the liquid interrupted.

As the supply of the carbonated liquid to the pressure -relieving chamber is accom plished by one lever and the discharge of the carbonated liquid by a second lever, no possible mistake in operating the device can occur. The actuation of one lever produces immediately a supply of carbonated liquid, while the actuation of the other lever produces the discharge of the same. As the hand always rests on the stationary handle when operating either the handle of the supply or discharge valve, the drawing off of the carbonated liquid from the fountain is accomplished in a very convenient and certain manner without any excessive foaming of the liquid.
