SERVICE APPARATUS FOR MALT LIQUORS.

SPECIFICATION forming part of Letters Patentl No. 348,668, dated September 7l 1886.

Application filed March 3, 1886. Serial No. 193,862. (No model.)

To all whom t may concern.-

Be it known that I, JOHN I). GRUBER, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain Improvements in Service Apparatus for Malt Liquors, of which the following` is a specification.

My invention relates to an apparatus designed, in the main, for serving that class of malt liquors known to brewers as ale/7 although it may be employed for beers classified under other names, and especially those of an unctuous character, which readily foam when drawn.

It is well known that when new ale is drawn from the cask it is nsually'allowed to stand in a measure for a time, in order that the foam may break up, as it is very difficult to draw it directly into the glass. This use of an open measure is very uncleanl y, and in summer time attracts flies and other insects.

The object of iny apparatus is to provide means for drawing the ale or vother liquor solid (or with very little foam) directly into the glass; or at will the liquor may be drawn through the same faucet directly from the cask into a vessel or glass; or, it may be drawn partly directly from the cask and partly from the receptacle of my apparatus, all as will be hereinafter described.

An apparatus embodying` to some extent the characteristics indicated above is shown in my Patent No. 2l0,0l8, dated April l2, 1881.

The novel features of my invention will be hereinafter fully set forth, and carefully defined in the claims.

In the drawings which serve to illustrate my invention, Figure l is a general sectional elevation of my improved apparatus. Fig. 2 is a detached sectional view taken in the plane indicated byline 22 in Fig. l. Fig. 3 is a detached sectional view taken in the plane indicated byline 3 3 in Fig. l. Fig. 4 is a longitudinal sectional view of the two-way faucet F, whereat the liquor is drawn.

Before proceeding to describe my invention, I will say that herein I have shown the servicefaucet connected close to the receiver or receptacle ofthe apparatus, for convenience of illustration; but this is not essential. They may bev separated to any desired extent, and be arranged with respect to each other in any way that is found most convenient.

A represents a receiver, which I usually make of sheet metal and of cylindrical form. It may, however, be made of any form and of any suitable material.

B is a glass-tube gage, connected to the receiver at` its top and bottom in the manner of a tube gage for a steam-generator. This gage has graduations formed by marks a a, and designated by the letters Pt., Qt., arranged in alternate order, as shown. These indicate both the quantity of the liquor at any time remaining in the receiver, and also the amount in pints drawn from it at any time. I usually employ different-colored paints for marking the pint and quart graduations, so that they may be readily distinguished from each other.

C is the eduction or 'delivery tube ofthe receiver, which depends to or nearly to the bottom of the receiver, and has a screw-threaded boss, b, which screws into the top of the receiver onto a packing-ring, c, whereby a gastight joint is produced. To the upper outer end of the yeduction-tube is coupled by a detachable union, D, the delivery-pipe E, which leads to the two-way service-faucet F, which will be more particularly described hereinafter.

On the crown of the receiver is mounted an adjustable pressure-valve, G, whereby, when the gaseous tension in the receiver exceeds a predetermined point the gas is allowed to escape and relieve the pressure. This device consists of a valve, d, which rests en a seat, e, and has a stem, f,whieh passes out through the crown of a screw-cap, g, which screws down into an internallyscrew-threaded flange around the valve-seat. Between the valve and this cap is arranged a spring, h, the tension of which is regulated byscrewing the cap g up or down, as will be well understood.

I will now describe the induction portion of my apparatus.

II is the pipe leading from the cask of ale, which may be placed anywhere, as in the cellar, for example. I have herein shown this pipe as branched at the coupling I, the main pipe going directly to the service-faucet F, and the branch H going to the receiver through a pressure-regulator, J. Both ,pipes H H might lead directly from' the cask, but I prefer to employ one main pipe, H, for the sake of economy and convenience7 and to couple the branch H to it by a union or coupling, I which I will describe.

K is a cock, usually of brass,which is placed in branch H', usually of lead pipe, and which controls the passage in said pipe. On the end of one of the arms i of cock J is fixed or integrally formed a plate, j, having a half-round groove in its face to receive pipe H (also of lead) and flanges with screw-holes therein. Another similar plate, k, embraces the pipe H on the opposite side, and screws Z Z, passing through the flanges of the plates j k, cause them to clamp the pipe H firmly. A hole of the proper size is cut in the side of pipe H, next Yto platej, and a short coned tube, m, on plate j, which may be the prolongation through the plate of the arm 'i of cock K, enters said aperture in pipe H, and thus opens communications between pipe H and branch H. Of course pipe H might lead to the cask and pipe H from the branch. rllhe ale on its way through pipe H to the receiver A must pass through the pressureregulator J, which I will describe with reference to Figs. l and 3. To the inlet a of the regulator is coupled the pipe H. rlhis inlet is prolonged inside of the shell 0 of the regulator, is closed at its inner end, and has an aperture, p, which is closed by a valve, q. This valve has two arms, 1' r, which pass up alongside ofthe inlet-tube, and are e0nnected to the valve-stem s. Between disks on the stem is clamped a rubber diaphragm, t, which forms a partition across the shell o. On the valve-stem, and pressing on a ilanged nut, a, on same, is a spring, c, the upper end of which takes under a screw-cap, w, that screws V.own into an aperture in the top of shell o.

,fr is merely an external cap perforated to admit air to the upper side of the diaphragm and designed to protect the regulator J from accidental injury or disarrangement.

y is the outlet of the regulator, which is coupled by a readily-detachable union to the induction-tube M of the receiver A. In order that the ale may enter the receiver in fine iets and be delivered in an upward direction, i usually slope or bevel the inner end of the tube M on the upper side and cover this end with a perforated plate,

Referring to Figs. l and 4, I will now describe the construction of the two-way faucet F. In the shell l is formed the usual conical bore to receive the plug 2, and also the axial outlet-passage 3, and two inlet-passages, 4 and 5. These inlet-passages are connected, respectively, each with one of the pipes E and H, usually through the medium of couplingtubes 6 and 7, which are arranged in the hollow arm S of the faucet.-. The plug 2 is usually cored out or formed hollow at the point where it passes through the shell 1, and it is provided with a wide port, 9, which is always in coincidence with the passage 3, as the plug 2 is or should be provided with stops, in the usual way,- to limit its axial rotation. The plug 2 also has a narrow port, 10, opposite the port 9, which former may, by the axial rotation of the plug, be placedto coincide with either one of the passages 4 5, or be placed between them, as seen in Fig. 4. Vhen the plug stands as seen in Fig. 4, I prefer to arrange the crosshandle 11 of the plug to stand at right angles to the faucet-axis, as shown. In this position the faucet is closed.

I will now describe the'operation ofthe ap paratus, premising that pipe H is connected below to a cask of ale under gaseous pressure, and that faucet F is closed, as seen in the drawings. The tension of spring e over the diaphragm of pressure-regulator J is regulated by screwing down or up the cap w, and the same is done to the spring of the regulator G on the receiver A. 'When the cock K is opened, the ale, under pressure from the Cask, will ow through pipes H and H, and enter the shell 0 of the regulator J through port p, depressing valve q, in order to force a passage, and will flow thence through outlet y and into the receiver A through the jet apertures In passing through the regulator J, the gaseous tension will be reduced and made uniform. 'Ihe degree of tension in the receiver will be regulated by the spring c. The pressure tending to open valve q is equal to the tension in the pipe H', and this is opposed by an upward pressure on the diaphragm t, which is equal to the pressure in the receiver. As the diaphragm is many times larger in area than the port p, it follows that a moderate tension in the receiver will close the valve q against a much greater pressure 011 the valve, tending to open it; but the tension of the spring c is opposed to the tension in the receiver, and consequently the difference between the initial tension and that in receiver A may be regulated by the spring c. This is generally effected primarily, and allowed to remain without change; but the tension in the receiver may be conveniently and readily reduced or increased, temporarily, by means of the regulator (lv-that is to say, by increasing or diminishing the tension of spring It by manipulation of screw-cap g. The ale flows into the receiver A until it is full, and its level is indicated on gage I3. If it be desired to draw the ale solid-that is, from the receiver-the attendant turns the plug 2 of the faucet F in the direction indicated by arrow-l2 in Fig. 4, up to the stop, which opens the faucet by way of passage 4, tube 6, and pipe E with the receiver A, and the ale flows out through eduction-tube C under a moderate pressure and with little foam. If it be desired to draw a measured quantity, this will be indicated by the gage B,as the inflow at induction-tubeM during the process of drawing will be comparatively inappreciable, and may be ignored. If the ale be too solid or dead 7 when drawn as above to suit the purchaser, the attendant may, before` IOO 'up to the stop, and this will have the effect to close the faucet to the receiver and open it to the ale-casl; direct through passage 5, tube 7, and pipe II. rlhis will of course supply the necessary aeration and foam, as will be well understood. lIhus the attendant has it within his control to proportion the quantities of ale under high and low tension to suit the tastes of customers. IVhen required, he may draw wholly directly from the cask.

If it be desired to remove the receiver for cleansing or for repair, this can readily be done without interference with the draft direct at the faucet F by simply detaching the couplings D and L, having first taken the precaution to close cock K. Ihe regulator J may also be removed by means of the detachable connection of same with pipe H.

In the bottom of receiver A is a screw-plug, a', which may be removed for convenience of rinsing out the receiver. The glass tube of gage B may be readily swabbed out an d rinsed by first removing the screw-cap b at the top of same.

From the above description it will be seen that my apparatus provides a closed receiver for the ale in lieu of the open measure or pitcher usually employed, thereby avoiding insects, and at the same time keeping a reservoir of the liquor under a reduced gaseous pressure, and not open to the air. As before stated, the attendant may at any time reduce the pressure in the receiver A by manipulation of the cap g of the pressurevalve G. The proper adjustment of the regulators J and G is a matter always within the control of the attendant and subject to his judgment.

I usually make the pipe 6 a little larger than the pipe 7, as the pressure in the latter is greater; but this is not essential.

A close receiver with an inlet controlled by a pressure-regulator near its top and an outlet from near` its bottom is fullyillustrated in my former patent, referred to; and these features I do not broadly claim herein.

Having thus described my invention, I claim- I. IThe coinbination, with the receiver provided with au outlet and an inlet and with a pressure-regulator arranged between the inlet and the cask from which the beer is drawn, of a two-way faucet, a pipe leading to said faucet from the outlet of the receiver, and abranched pipe from the beer-Cask, one branch of which leads to said two-way faucet and the other to the receiver through said pressure-regulator, substantially as set forth.

2. rlhe combination, with a two-way faucet, substantially as described, having two tubes, 6 and 7, whereby it is coupled to the pipes E and H, respectively, of the said pipes, the former connecting the faucet with the receiver and the latter connecting the faucet with the liquid source direct, the receiver A, provided with an inlet, M, the pipe H', which connects the inlet of the receiver with the liquid source, and the pressure-regulator J iu the pipe which supplies the liquid to the receiver, whereby the attendant is enabled to draw at will liquid from the receiver or the liquid source direct 7o through the same faucet.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
