' Application led Angnst1|9 1899. v Serial No. 727,754. (llo model.) i v To @ZZ whom" 'it may 'concern' i Be it known that I, .ARTHUR KLEINRELDT,

acitizen of the United States, residing in Newv Yorlgborough 4of Manhattan, and' State of New York, have invented certain new and useful Improvements in BeerSiphons, of which 'the following is ,a specification.

This invention yrelates to'certain improve! 'ments `iii-beer sipho'ns'or vesselsl of that class in which are contained fermented liquids un-l d'era pressure ofl carbonio-acid gasand from which the liquid can bev drawny through a' valvcd spout under pressure of the'gas until the vessel is entirely emptied. l vA number of,

devices have heretofore been proposedy for thisfpurpose, but so far withlittle, practical success,partly for the reason thatthe vessels were too cumbrous and little adaptedfor vcfOnvenient refrigerationand partlyfor the rea` 2o son that the mechanism by which the car# ,bonita-acid gas was suppliedv from its receiver to the 'liquid-containing'vesseldid `:not func- Wheninnse. i The object of this inventionA is to supplya tion with'a suiiicient degree of reliability der pressnreof carbonio-acid gas whichhas and eiec'tive manner,so that a suflicient quantity of carbonio-acid gas is supplied for forcjing outvall the liqud'contained in the vessel the same, anf'opening in' the' bottom of said. receiver, .a valv'for opening and closing said consists of a beerfsiphon which comprise a under uniform pressure; andthe inventin carbonio-acid secured to the neck-of the vesopening,a diaphragm connectedwith the stem of said' valve,achannel connecting. the space onthe pressure side of the diaphragm with a v fbor'e `in the neck of the Vreceiver and with the i interior of the .liquid-containing vessel, openlings .for connecting the-space at the opposite side 'of .the diaphragm with 'the atmosphere,

Vand avalved siphon-tube for'drawingoi the liquid under pressure from the liquid-con- 'i taining vessel'.

The invention consists,furtl1er, of. certain details of construction, which ,willbefully described hereinafter, and iinallyfpointed out 'inthe claim. r

In the accompanying drawings, 'Figure 1 represents :aside elevationxof my improved beer-Siphon. Fig. 2 is a vertical central secl tion-,through the1 head of the s iphou, drawn on alarger scale; vand Fig. .3 isa ,bottom-view,

Similar letters. of reference indicate 'corre-4 sponding parts.

Referring tothe drawings, A represents a4 .vesselwhich is preferably-made otglass in the general-shape ofail-ordinary s'iphon for carbonated Waters, sai'dsiphon being made oli sufficient size to containfone, two, or more gallonsof fermented liquid, such as,beer,ale, Wine, &c.- The liquid vessel Aecan also be madeof steel or. other. suitable material,

though it is preferable .to 'make it offglass, soI fjthat'the contents of 'the vessel canl be readily seen.' .The vessel A is providedwth-aneck ci, having an interior threadgintofgwhich is tightly .screwed and cemented a" bushing b, into which the threaded neck/r of a'carboni'c acid receiver R is screwed. A ringshaped gasketjcl, of elastic-material, isinterposed be-- tween the shoulder r ofthe neck of 'thefre-l ceiver R :and' the recessed top part of the ,bushing b, so as tosecurethe tightiitting of the receiver to thenec'k'of 'the liquidi vessel, ,The carbonio-acid 'receiverR is preferably made of copper.- or other suitable material, its upper part being 'dome-shaped, while'its vlower edge is securely soldered or brazed into the upper half of a diaphragm^casingiD,-the lower Vhalf of 'which is secured :by s crewsb to the upperhalf, said two halves holding the sheet-metal diaphragm D tightly-imposition between their circumferential" rirns.-A 'The' neck r of the receiver-R isjcast'integral with the lower half of-the .diaphragm-'casting D, said lower half being provided with a number'of-.openings d', so that atmospheric pressurejs exerted on the 'under side of: the dia- Phmgill-D'f e l The; receiver 'R s provided vat its central top part with anl opening having au interiorly-threaded bushing e, into which is screwed a plug E, which has a central perforation f, the inner end of which is closed by a springactuated valve ff, retained by a'perforated cage f2. The valvedplugE serves forcharging the receiver R with carbonio-acid 'gas under pressure'. The carbonio acid'is preferably supplied'to the receiver by connecting .the upper threaded end of'the plug Ewith -pre'ssure in the receiver fa tube connecting it with the outlet-valve of a cylinder lcontaining liluid carboui'c acid. -As soon as the required 4 The stem g of the valve g passes throughl the has been removed, and therebythe position' opening o and is connected with the center of 4the diaphragm D'.

The valve q is 'provided with an interiorly-threaded socket, so that it can be adjusted higher or lower on the threadf 'ed upper end of the valve-stem. The valve g' has' a nick gz in its head, so that a screwdriver can be inserted through the opening in the 'top of the receiver R after the' plug E of the valve g on its stem' adj usted higher'or lower relatively to its valve-seat. A' channel hin the-upper half' of the diaphragm-casiog'h D leads from the space above the diaphragm theower half of the casing D and then in an inclined direction in the same to a center bore h' in the neckr, as shown in Fig'. 2, S'o as to place the space above in communication with ythe interior of the liqvuid-containing vessel. The upper end of the bore h' isclosed bya springactuated escapevalve h, sothat in case the pressure in the liquid-containing vessel should rise'above the required pressure the escape-,valve will be liftedagainst the tensionnh'tsspringand the surplus gas 'discharged into the space below the diaphragm and from thesame into the athere. -As soon as the normal pressure for which the escape-valve is set is established inthe liquid vessel the Aescape-valve will close again the central bore of .the neck fr. The lower halfl of the valve-casing D is further providcd with an outlet -channel 'L' of Y larger size than the channels'h h', said outlet-channel being provided at its inner -end with a nipple i, to which .a siphon-tube F is applied by means of an elastic sleeve s, said sleeve permitting a certain play to the si phontube, so that during transportation or by egree of pressure is provided with an opeu` ingo, having a beveled `valve-seat o', on which rts tightly a correspondingly-shaped valve g.

the diaphragm give suiciently'so as to be prevented'from breaking. The outlet-channel is provided with an exteriorly-threaded nipple i* at its outer end, to which a discharge-spout G, having avalve, faucet, o r other'suit'able device G', is applied. This discharge spout or nozzle G is screwed onto the nipple of the outletchannel, which nipple is preferably cast integral wth the lower half of the diaphragmcasing D. Anysnitable construction of valve or stop-cock for the discharge-spout may be used, that shown in the drawings being in the nature of an ordinary lever-actuated valve, such as commonly used on siphonsfor aerated waters.

The receiver R is provided at diametricallyopposite points of its side wall with sockets for receiving the inwardly-bent ends of a pivoted bail B, by which the siphon can be conveniently carried.- When the bail is not in use, it assumes an inclined position of rest, as shown in Fig. 1. The operation of my improved beer-siphon is as follows: The fermented liquid is charged 'into the liquid-vessel A under pressu're'ot car- 'bonic-acid gas through the discharge-spout in the same manner as the siphons for aerated waters are charged, or the liquid is charged without -pressure into the liquid vessel by uuscrewing the neck of the receiver from the bushing in the top part of the vessel and then.

.supplying the vessel with the determined quantity of fermented liquid. The receiver is then screwed again into position in the bushing of the vessel. The plug E is then removed ,and then connection with a cylinder containing liquid carbonic acid establshed.-

As soon as the required pressure of carbonio acid in the receiver is obtained, which is read off on a suitable pressure-gage connected with the Asupply-pipe leading from the' cylinder to the receiver, 'the cap is placed on the plug E and the receiver thereby tightly. closed. During the charging of the receiver wi th carbonicacid gas the diaphragm is in its normal posi- -tion' with the valve g in open position-z'. e.,

vaway from its seat-so that the gas can pass through the opening or port o into the space above-the diaphragm and through the channel h h into the spaceabove theliquid in the vessel A. 'As soon as the required pressure .is established in the receiver Rand the liquid-containing vessel A the back'pressure of the'gas from the liquid vessel will act upon the diaphragm D', so that it will bulge downward and close the valve g tightly on its seat o', so as to Iinterrupt the connection of the liquid vessel with the receiver. ,The parts remain in this condition until liquid is to be drawn from the vessel A by opening the valve of the discharge-spout. As soon as the discharge-spout is opened, the liquid will flow through the Siphon-tube and the spout into the receptacle held below the same. The gas-pressure in the liquid vessel A above the liquid is reduced during the discharge of the liquid, and thereby ythe pressure on the diaphragm reduced, so that it will return into its normal position and lift the valve g, Wherev by a new supply of gas can pass from the receiver to the liquid vessel. As soon as the valve of the discharge-spout is closed and the p outiiow .of liquid interrupted, the back pressure ofthe gas in the liquidvessel will again act on the upper surface of the diaphragm and press the same downward into slightlybulged shape, so as to cause the valve to be seated firmly on its seat and interrupt therevby the connection of the receiver with the liquid vessel and the supply of gas to the latter. To secure'the required pressure yin the liquid vessel, the valve is adjusted oniits valve-stem either in upward or downward direction. When the valve is adjusted higher on its stern, a greater pressure is necessary to close the valve thanvlwhen the valve is adj usted lower on its stem, in which case -a smaller pressure isrequired.

My improved beer-Siphon has the advantages of compact shape, so as to be easily cooled either in thez refrigerator or cooler. .All the parts by which the carbonio acid is supplied to the liquid vessel are fully inclosed -and not liable tobe rendered inoperative. y The siphon can be manufactured at compara- -tively-small expense and enables the consumer to be supplied with fermented liquids in larger quantities, such as one or tvvoI or more gallons, in place of delivering them in bottles in the usual manner. As the liquid drawn from the siphon is always under pressure of carbonio-acid gas it is more refreshing and palatable and can be drawn 0E at differenttimes and in any desired quantity, the siphon being then returned to the refrigerator, so that its contents are kept cool and ready for use Whenever required.

Having thus described my invention, I 7

claim as new and desire to secure by Letters Patent- The combination, with a liquid vessel, of a carbonio-acid receiver provided with a neck secured into said liquid vessel, said neck having a longitudinal bore, a diaphragm-casing at lthe lower part of said receiver provided with an opening communicating with the atmosphere, a diaphragm supported by said casing, a valve located in the receiver, a stem connecting said valve through the opening or port in the bottom of the receiver with the diaphragm, a gas-supply channel connecting the space above the diaphragm with the liquid vessel, a spring-actuated escape-valve at `the upper end of said bore, an outlet-channel located in the lower part of the diaphragm- Y casing, a Siphon-tube connected with the inner end of said outlet-channel, and a valved discharge-spout connected with the outer end of said outlet-channel, substantially as setl forth. i l q In testimony that I claim the foregoing as my invention l have signed my name in presence of tWoV subscribing Witnesses.
