BARTOLOMAY KRALL, OF BOSTON, MASSACHUSETTS.
DRAFTMCOCK.
SPECIFICATION forming part of Letters Patent No. 608,874, dated August 9, 1898.
Application filed october 2a, 1897.
To (all whom t may concern.-
Beit known that I, BAnToLoMAY KRALL, a citizen of the United States, residing at Boston, in the count-yof Suiolk and State of Massachusetts, have invented a new and Improved Draft-Cock, of which the following is a specification.
By the Within-described invention there is provided an improved draft-cock for sodafountains or like apparatus which deliver liquid under pressure. The improved draftcock may -be so constructed that by a single continuous movement of a handle the liquid under pressure is delivered rst to the outlet, which may consist, first, of a jet-nozzle and next a spray-nozzle, and so that the cock when closed shuts the entrance or intake from the source of supply by means of a stop, the gates or valves leading to the outlet aperture or apertures being relieved of pressure when theintakeis closed. Further, the draftcock is provided with an outer shell which surrounds the liquid discharging devices, this shell being separable from its seat in such manner that Without interfering with the relationship of the valves to the intake and outlet openings the liquid-passages of the draft-cock may be exposed for cleaning. This outer shell of the draft-cock is further so proportioned and adjusted with relation to jet and spray outlets that the jet is delivered unhindered by the outer shell, and the spray is, on the contrary, efectually distributed and scattered so as to flow from the nozzle of the apparatus copiously and with the least possible force. Thus the improved draft-cock is especially well adapted to use with sodafountains where the two distinct kinds of delivery of liquid are required.
In the drawings hereto annexed, Figure 1 is a vertical cross-section of the draft-cock, showing all its parts. Fig. 2 is a side elevation of the valve and the screw-threaded stem by which it is operated. Fig. 3 is a crosssection of Fig. 2 along the broken line x ce, viewed from the right. Fig. 4 shows the outer cap of the shell of the draft-cock as viewed from the right of Fig. 1. y
The principal operative portions of the dcvico consist of discharge-chamber,4iJ which ineloses a valve-carriage 9 and is secured by a screw-threaded neck to a corresponding faces.
Serial No. 656,634. (No model.)
(Not
Vithin the discharge-chamber 4 is situated the valve-carriage 9. This valve-carriage is moved toward and from the intake-aperture 12 of supply-pipe 1 by an ordinary handwheel 14 on a screw-threaded stem 13. The valve-carriage 9 has two operative valve-sur- One, the compression-stop 10, serves eiectually to close the intake-aperture 12 by `being pressed iirmly against the lip 11 when hand-wheel 14 is turned toits extreme righthand position. The other operative valvesurface is in the cylindrical'portion of the valve at 17. This valve-surface turns and slides with the movement of screw 13 in the cylindrical barrel of discharge-chamber 4. This valve-surface serves as the gate to open and close the apertures 19a and 21, which appear on Athe lower and upper sides, respectively, of the discharge-chamber 4. This ,portion of the valve will therefore be called the gate in order to distinguish it from the stop 10.
In order to insure easy Working of the draftcock, the gate 17 shouldhave only a good sliding t on the -inside of the dischargechamber 4. When a slide-valve is depended on to out off pressure, such a sliding lit is liable to leakage if the fit is loose enough to permit ready movement, and, on the other hand, if the fit is tight thevalve is liable to stick until worn again by usage to the slack fit, which permits leak. By the structure of the valve 9 leakage is prevented, while at the` same time a very free sliding iit between the gate 17 and discharge-chamber l may be preserved. The stop portion 10 of the valve 9 closes the intake-aperture 12 by pressure,
,which may be regulated to serve the conditions of liquid-pressure at any time prevailing. When the intake-stop 10 is firmly closed, there can be no leakage by the sliding sur- -faces of thegate 17, and when the valve 9 is opened and stop 10 removed from the lip 11 any leakage of liquid r'through and by the gate 17 will be unnoticed for the reason that IOO upon the opening ofthe valve the liquid is delivered throughits regular channels, as desired. The openings of the gate 17 are shown at 19 and 20. These openings are so arranged that one only of the apertures 19 and 21 shall be in communication with the interior of valve 9 at one time. The aperture 2O is therefore set nearer the intake end of the valve than aperture 19 and not directly opposite, so that a still further left-hand turn of the wheel 13 is required to bring aperture 20 into position to register with the outlet 21 after outlet 19 has passed its corresponding opening 19:.
Imagine the hand-wheel 14 removed from its stem and the valve-carriage 9 inclosed in position so that the supply-pipe is effectually shut by the stop 10. Although the valve-chamber 4 is entirely uncovered, even though the jet and spray nozzles 1S and 22 are removed, no liquid can escape into the valve-carriage or leak from the discharge-chamber. First, the middlebarrel 3 is screwed to the outer thread of flange 2, which is integral with the supplypipe 1. `When the barrel 3 is in position, the cap 23 is slipped on over stem 13 and screwed to the barrel 3. lhen jet-nozzle 1S and spraynozzle 22 are screwed to the barrel of the discharge-chamber 4, and the outer nozzle 7 is screwed to the neck 8 of barrel 3 and the dome 5 similarly screwed on the neck 6. These parts can be removed in an inverse order without disturbing the valve-carriage 9 and its relationship with the several inlet and outlet apertures, and thus without shutting off the pressure from the source of supply which leads to the supply-pipe 1 or, as is often the case, waiting until the pressure from the source of supply has been exhausted. At
f any time all the parts of the improved draftcock which are liable to collect dirt of any kind may be removed for cleaning Without disturbing the channels of supply with which the said fountain is provided.
The parts of this draft-cock which remain to be described are as follows: The jet-nozzle 13 is in the usual form and projects directly down from the valve-chamber 4 to the center of opening 23a. The spray-nozzle 22 is on the opposite side of the valve-chamber 4 from the ljet-nozzle 13 and points up into the dome 5.
This dome is not closed at the top, but, on the contrary, is provided with an opening 2S, which leads into a hollow cap 27, which in turn is open to the air at 29. When the draft-cock valves are closed and there is no pressure on the inside of the shell, this aperture is open and permits the passage of air through the shell. A bell 24 hangs from the top of the dome 5 by a stem 25, which is open at the top and provided at its lower portion with slots 30. A collar 31 on this hollow stem 25 rests on the upper neck 26 of the dome 5 and sustains the weight of the bell 24. At the top of the bell 24 is a washer 32, which when the bell is pressed upward closes the aperture 2S.
In Figs. 2 and 3 the construction of the valve 9 and the location of apertures 19 and 2O and the passages 15 are shown.
The operation of the improved draft-cock is as follows: Assume the hand-wheel 14 turned to its farthest right-hand position and stop 10 closing intake 12. The sliding gate 17 is then in such position that the apertures 19 and 2O are closed by the cylindrical surfaces of discharge-chamber 4. In Fig. 4 assume the dotted line 14n to represent a spoke of the hand-wheel 14 when the valve is in its closed position and spoke 14a standing at the arrow-point marked c. To open the valve, turn hand-wheel 14 to the left until spoke 14n stands opposite the arrow-point marked j. lVith the hand-wheel in the latter position the operation of the screw-threaded stem 13 has withdrawn the stop 10 from the lip 11 of the intake 12 and brings aperture 19 lopposite the opening 19a in the dischargechamber 4, this opening 19 communicating with the jet-nozzle 13.
The admission of the liquid under pressure into the discharge-chamber 4 by the removal of the stop 10 from its seat places the jetnozzle 18 in free communication with the source of supply and a fine sharp stream of soda-Water is directed into the glass. As soon as the spray or hat stream is desired hand-Wheel 14 is turned still farther to the left, so that spoke 14 stands opposite the arrow-point s, Fig. 4. This last movement of the wheel 14, stem 13, and valve 9 has moved aperture 19 away from the opening 19a and brings aperture 2O opposite opening 21, which leads to spray-nozzle 22. The jet of water flowing from nozzle 22 into the dome 5 impinges against the bell 24, which immediately is lifted and closes the aperture 28 by .means of the washer 32, thus preventing any undesirable escape of liquid through the upper opening of the dome.
From the dome 5 the spray flows around the valve-chamber 4, through the barrel 3 and outer nozzle 7, and out at the opening 23 in a copious stream free from undue pressure. When the glass belouT the draft-cock is full, a quick turn of the wheel 14 to the right transfers the spoke 14t from position s, Fig. 4, to position c and closes the valve by com- IIO pressing the stop l against the lip ll. The pressure within the dome being relieved by the closure of the valve, the bell 24 falls to its normal position and the air-passages in the top of the dome are again opened, facilitating the escape of carbonic-aoid gas and hastening the drying of the interior of the shell of the draft-cock by the introduction of air. This serves to prevent the greater part, if not all, of the dripping which usually follows the closing of a soda-fountain cock.
The form of draft-cock, with its dischargechamber, intake and outlet valves, jetfapertures, and shell, which is shown in the drawings and hereinabove described is believed to embody all the features which render it veasy to-construct and simple and sure in operation. It is thought best to employ a cont pression-valve for the control of the intake, for the pressure in the supply-pipe of such apparatus as a soda-fountain not infrequently rises as high as one hundred and eighty pounds to the square inch and atight closure is necessary to hold such pressure in check; but some other form of valve might conceivably be used to bar the entrance of liquid 'from the supply, and thus relieve the 0utletvalves of duty when the cock is closed, and this invention be embodied in an apparatus diiering in detail from the one shown herein, while employing the same underlying idea. The complete draft-cock 'for soda-fountains should contain both the jet and spray nozzle and modes of delivery. This, however, need not always be the case. The arrangement of intake-stop and valve, discharge-chamber, Y
and outletvalves herein shown may be used to advantage in apparatus `Where only one outlet-aperture is used.
I claim- 1. In a draft-cock, a supply-pipe, a discharge-chamber directly secured thereto and provided with a discharge-valve and its con trolling-stem,ashell,enveloping thedischargechamber and formin ga space around the saine, the said shell secured to the supply-pipe by a connection external to the discharge-cham ber connection and removable therefrom independently of the discharge-chamber, the valve-stem being secured in its relationship to the valve by connections through the dischargechamber independently of the surrounding shell, substantially as described.
2. In a draft-cock, the combination with a supplypipe, of a discharge chamber and valve, the discharge-chamber provided with outlet-apertures, a shell enveloping the dischargechamber provided with a dome on one side of the discharge-chamber and a nozzle on the other, one of the outlet-apertures from the dischargechamber directed to the shell-nozzle, the other directed to the dome.
3. In a draft-cock, thecombination with a supply-pipe of discharge-outlets and a controlling-valve therefor, a shell enveloping the discharge devices of the pipe and forming a chamber around said discharge devices, said shell provided with a nozzle at its lower end and with a normally open air-passage at its upper end, substantially as described and for the purposes set forth.
4. In a draft-cock, the combination with a supply-pipe of a discharge chamber and valve, a shell enveloping the discharge-chamber, said shell being provided with a liquid-nozzle and an air-passage, and a valve in said airpassage adapted to close in response to fluidpressure from Within the shell.
