VALVE-FITTING FOR SODA-WATER APPABLTQ'S.

Specification of Letters Patent. P t nted Sept. 14, 1909.

Application filed August 4, 1908. 'seriel No. 448,888.

exactdescription as will enable any one I D ing and discharging ofthe cylinder without frequent removal of the valve-fitting being skilled in the art'to-which it appertains to inake and use the same, reference being had to the accompanying drawings, forming part of this specification.

The principal objects of my presentin -vention are to provide a soda water fountain valvefitting having but a single hand-valve controlling the passage through which the water and charging gas are introduced and the charged water withdrawn, and which fitting at the same time permits both chargremoving the fitting, thereby avoiding the necasity of. removing the valve fitting to charge the cylinder, as has heretofore been the general practice, the drawback to this the-rupturing of the joint between the blocktin lining of the fountain and the bung or ipe-connection to which the valve-fitting is connected. D

With these and other ob ects 1n View, my

invention consists in the various novel and peculiar arrangements and combinations of the several diiferent parts of the apparatus, all as hereinafter fully set forth and then pointedoutin the claims. I

I have illustrated types of my invention in the. accompanying drawings. wherein Figure 1 is a longitudinal vertical sectional view of a soda water fountain or cylinder shown as. having my improved fitting appliedthere'to. Figs. 2 and 3 show, respectively, enlarged wrews of vertical central sections of the fitting shown detached, the sections being taken at right angles to each other, in these two views. Flg. 4,1s a view of a central longitudinal section of a-modified form of the fitting. i V

Referring to the drawings, in which like numbers of rcferencel dislgnate like ptarts l at 1 is a sore ountain cons1s 1ng iii riij liiidr made of suitable metal to withstand the internal pressure from the conindex 1 and the linin 2 and to which the lining is secured in on er to form a gas and water tight joint. The exterior of the outer "end of the nozzle is provided wit-ha screw thread ,on which works a nut 6 for drawing the nozzle upwardly and securely locking it in place in the cylinder. The fitting comprises a valve casing 7 provided with a valve chamber 8 in which works a valve 9 which is made of suitable soft material and seats itself on the annular ridge 10 which is rounded as indicated to revent, cutting the soft material of the va re. The ynlve is provided with a stem ll which has a screwthread 12 working in a corresponding screwthread upon the interior of the removable part 12 which at its inner end has an external thread 13 fitting a corresponding interniil thread in the tubular extension 14. A washer 15 is placed between the part 12 and tlie'end of the tubtdar extension 14 to make a gas and water tight joint and the outer end of theJ'alve-stem 11 passes through a removable cap 16 which has an interior screwth'read l7 fitting a corresponding exterior' thread on the outer end of the removable part- ]2". and a soft washer or packing 18 1s placed within the cap, as indicated, to make.

the joint gas and water tight. The valve casing has a branch 19. through which ex-' lends a passage 20 counnunicating with the lower end of said branch and with the valvechamber 8, the valve-seat 10 being at the inner end of this passage 20. The exterior. of

the branch 19 is screw-threaded at '21 to fit the internal screw-thread of the pipe-section or nozzle 4,'and it is also provided with a, lateral flange 22 in the under face of which is sunk a soft annular washer 23 which bears down against the upper end of the pipe-seetion 4 when the fitting is screwed down hard and thus provides a gas and water tight joint between the fitting and the ipe-sect-ion 4.

To'the lower end of the brane 19 of the fit-- ting is soldered or suitably secured the tube 24 which is used for both filling the cylinder and witlulrawing the contents. and this pipe extendsto near the botttim of the cylinder,

as indicated in Fig. l. The fitting '7 is also 5 provided with another lateral Branch or extension through which extends a passage liiCOlHlTilllllCiltlllg with the valve-chambers so that this valve controls the communic:

tion between the passage 20 and the passage :56. This branch part :35 is provided with an external screw-thread 27 by means of which it may be coupled with any device for withdrawing the contents of the cylinder or with the pipe for charging the water within the cylinder with carbonic acid gas; Ifit beattempted to fill the cylinder with'liquid, by

opening the valfia J and forcing the liquid in, it will be found that the necessary quantity of liquid cannot thus be forced in without some means of venting or permitting a quantity of the contained air to escape. for

this reason it has been the custom to remove the fitting in order to obtain the large opening provided through the pipe-section a and to then fill the cylinder by a pipe or hose inserted in the nozzle and to the desired height,

though, of course, these cylinders are not entirel y filled with liquid as some considerable space must be left for the compressed gas with which the water is charged.

In my present invention, I provide an air vent which comprises a duct or passage extending through the fitting and connnuuieating at its lower end with the short tube 130 which runs down parallel with the main tube 24 and is soldered thereto at 31. he outer end of the air duct 2!) extends through a boss or'projection 32 which is provided with a hand valve comprising a cap haviag an interior screw-thread 34 working on acorresponding screw-thread on the boss or extension 32, and this cap is provided with a lateral opening 36. The air vent 29 opens upon the outer end of the boss or extension 32 which forms practically a valveseat for the valve 37 which is made of soft material and this closes by screwing down the cap tight upon the boss, as shown in Fig. *1. This cap is provided on its exterior m) with flat faces 38 like those of a nut for receiving a wrench to turn down the valve hard to L'll) t it and to loosen the same when it is desired to vent the cylinder, the vent :21) being in free counuunication with the .55 lateral perforation 36 in the cap when the cap is partly unscrewed. as shown in Figs.

2 and 3. In order to prevent the cap from 3 becmfllng detached, 1 provide the same with an inwardly projecting pin 35) which takes so into an oblique slot 40 in the side of the boss 32, and this pin and slot serve to retain the cap from detac luuent, as will be readily understood from the drawings.

'In Fig. 4, I show another form of the ii tin, it lacing. substantially the same as thatdescribed in the other figures with the enception that instead of the air vent 29 opening through a boss upon the upperend of the fitting, it opens into a socket 41 in the side of the fitting which socket or cavity is provided with an internal thread for receiving the exterior screw-thread {'2 on a plug 43, and this plug is provided with an L-shaped passage l4 extending longitudinally into the same and then laterally so as [0 open on one side of the plug aswell as the end, as indi- 'cated in Fig. 4. This plug is provided with a lateral flange 45 beneath which is a washer at; for bearing upon the outer end of the socketed part 47. This washer 40 and the SQ end of the socketed part 47 form practically a valve and its seat, so that the vent may be closed by screwing the plug in tight, in which case the vent 44 opening upon the side of the plug .will be completely covered and 35 closed air and water tight. By unscrewing this plug partially or entirely the vent may be opened. l-he outer end of this plug is provided with flat faces for recei ing a wrench like the part 38 of the valve cap 33 in the other construction.

The upper end of the fitting T in Fig. -'l provided with a rounded projection 50 which like the end of the valve cap 33 in the other figure, may he used as a handle in rolling the cylinder 1 on its lower end from place to place, the same as a barrel is rolled by a person in moving it from one point to another.

It will now he understood that with this I venting arrangement, thecylinder may be filled with water to the required height without. removing the fitting at all, so that the same becomes practically a permanent fixture of the soda fountain or cylinder. In

charging these fountains, it is the practice to only partially fill the vessel in order to leave above the water therein a space for the charging or carbonating' gas which is also injected into the fountain. The length of 11!).

the vent-pipe 30 depends somewhatupon the amount of liquid with which the cylinder is to be charged so that where a lessquantity of water is to be used the vent-pipe 30. is made longer than when the cylinder is to be 1 charged with'more water. Accordingly if desired. this ent-pipe 30 may be varied in length depending upon whether the cylinder is to contain a less or greater amount of \vatcr. By attaching a pipe, such as -18. to the lateral branch the empty cylinder may have the water forced therein to fill it, by opening the valve 9 by me'ans of the handle '49 secured to the end of the valve stem 11 at the same time opening the valve of the vent passage 29. Under this condition, as the water is forced in the cylinder, it begins to compress the air above the water, as the water enters much more rapidly than the air can escape through such a small passage as 29. When the water rises in the filling o oration to a point above the lower end of t 1c vent pipe 30.1ll0fi1'8n'8l1l8 of the air above the water will be' 'm to force th water up through the vent pipe and this wi '1 continue until a quantity of \vater'is forced out of the outer end of the air vent so as to be seen by the operator. and this indicates that it is time to shut oh" the supply of water as the same has then reached the required height in the cylinder. .In this way the venting arrangenwnt also serves as a gage for informing the operator as to the quantity of water in the cylinder and letting him know when to stop the filling process. Ordinarily, the proper height ofthe water is ascertained in filling these cylinders with the fitting removed by the operator inserting a'sticlt or rod in the nozzle 4 and withdraw-' ing it to note the height of the water in the cy inder.

It will, of course. be understood that the outlet or eduction port of the air vent may be located upon any part- 0 the valve casing. l hav ng herewith shown two such loca tions both of which provide very convenient arrangements. Of course, any well-known form of hand valve may be'nsed to control the venting part.

Having thus described my inventionwhat I claim and desire to secure by Letters Pfitx eat is:
