SIPHON-BOTTLE.

' SPECIFICATION forming part of Letters Patent lIo. 361,400, dated April 19, 1887.

Application filed May 6, 1886. Serial No. 201,366. (No model.)

To all whom it may concern:

- Be it known that I, CHARLES DE QUILL- FELDT,a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a new and useful Improvement in-Siphon-Bottles, of which the following is a specification. 7

The invention relates to the top or valve mechanism of so-called siphon-bottles, or such as are used for carbonated mineral waters, in which the pressure of the carbonic-acid gas with which the beverage is charged is the means by which the liquid is expelled through the spout when the valve is opened.

The invention comprises improvements in thefollowing respects: the construction and combination-of parts, whereby, when the valve is open, direct communication is formed with the spout without an intermediate vertical channel, while at the sametime the packing around the valvestem is pressed tightly aron nd the same, so as to cause no leakage through the bore in which the valve-stem fits and without pinehingthe packing between the said valvestem and bore, and when the valve is normally closed the lever rests against a positive stop at the upper end of its stroke,so as not to lessen the throw on the depression or downward stroke needed to sufliciently open the valve; also, the construction whereby the valve-lever is kept steady, instead of playing loosely, as heretofore, thereby making it more agreeable to operate and facilitating its depression in such a manner as to effect a gradual opening of the valve and prevent sudden spurts of the liquid; also,thc construction whereby the packing in the valve-rod tube tightens its grip around the valve-stem in proportion as the vertical pressure increases.

The improvement will be hereinafter fully described, and specifically pointed out in the claims,reference being had to the accompanying drawings, in which- Figure 1 represents a vertical section of the top and upper part of the glassof a siphonbottle constructed according to my present improvement. Figs. 2 and 3 are detail sections of two modifications of the valve-stem packing.

A is the bottle, and B the ordinary glass tube reaching down nearly to the bottom of the bottle, and through which the liquid. is pressed up to the spout by the pressure of the gas within the bottle. The pipe B is provided at its upper end with the usual flanged top or fitting,b,of soft metal, the upper end of which fits in a corresponding recess in the lower end of the top piece,G, which latter is united to.

the bottle by being threaded and screwed down upon the threaded ring a, made of two semicircular pieces which embrace the bottle-neck and are retained by the shoulder on the bottie-head, as usual. A packing-ring, 1), makes a tight joint between the top piece, 0, the flanged piece I), and the upper end of the bot tle simultaneously.

In line with the glass tube B the lower end surface of the top piece,O, is provided with a. preferably spherical cavity, 0, and in the side of the said cavity is formed the inner end opening,n,of the spout c. i

D is the tube in which the valve rod or spindle E is arranged, as usual. The bottom of the said tube D is concave at d, where it forms a seat for the packing of the valve-stem e, which works in a bore through the bottom of the tube from the center of the cavity (1 to the metal, and has at its upper end, beneath its top flange, a transverse slot, d.

Iis the valve-lever, the inner part of which is of hard metal, to which the outer part or thumb-piece, made of soft metal, is united in the casting. The inner end of the lever I is notched upon its upper surface, or formed in the shape of a hook, 1;, which enters a correspondingly-madc little socket in the side of the tube D, and engages with the said notch a hard-metal pin, (1, which is secured by being cast in place, so that neither pin nor socket will show from the outside of the casting. The portion 1' of the lever I, by which it engages the spindle E, is of the same height as the slot in 'which it fits, and its opposite upper and lower surfaces are curved to a radius of half the height of the slot, so that when the leveris depressed to move the spindle downward and open the valve F the said portion 5 will always move ewenly and without play in the slot d.

H is the valve-stem packing. This is made of a rubber tube, as shown in Fig. 2, or preferably of a hollow sphere,with diametricallyopposite perforationsto receive the valve-stem,

as in Fig. 3. Upon the upper end surface of the said packing is placed a metallic washer, g;

fitted to move up and down slightly in the bore I 5 of the tube D. When the spherical packing is er 9 is depressed against the packing H by the force of the ordinaryspiral spring, G, which surrounds the spindle,the packing will assume the shape shown in Fig. 1, pressing, both at its up- 2 5 per and its lower end, tightly around the valvcstem e, the tightening increasing with the increase of the pressure upon the spring,as when depressing the lever I to open the valve for drawing liquid from the bottle.

The upper end of the spiralspring G (which heretofore always was arranged to bear against the under side of the end flange of the spindle, as shown in United States Patent No. 182,612, and consequently closed the valve independ- 5 ently of the greater; or less steadiness of the ,1,.. everlbe s,iaslshow iE g. 1. upon i men; throughgtghe; slot; din' I j j while; compressing the sp pressure of the spring."

The said stop z" prevents the lever from being pulled out without a special manipulation for the purpose. The upper end of the tube D is covered by a cap, d as shown in Fig. 1.

In siphon-bottles as heretofore constructed the outlet or the channel to the spout was the same as the opening through which the valvestem works, the spout-opening adjoining the said channel a distance above the valve. Above the said spout-opening the spindle was surrounded with three flat washers, of metal,

induced a tendency to leakage through the valve-rod tube, and madeno provision for keeping the lever steadily and firmly in contact with the spindledefects which, by my present invention, are overcome.

As samples of the state of the art previous to this application, in addition to the patent before mentioned, I referto United States Patent N 0. 336,463; English Patents No. 2,049 of 1860 and No. 1,450 of 1882; also, French Patent No.. 25,699 of 1860; and I do not claim anything shown in the said patents.

As shown and described in one of the above mentioned patents, English Patent No. 2,049,.- it is old in siphons to employ an elastic conical-shaped valve having a flat upper surface in connection with a correspondingly-shaped seat; but I have found by practical trial that such a valve is open to the following defects: First, there is so much of the surface of the valve tightly wedged against the wall of the sipho 2 and t vea eat that; it Every soon isticks -and wedges fast secon -when not .1sisnb ectdraws it outer-shape, so {that its keep it tight; third, when. p Z818: itimust be inorder to fit tighathe wedg; iing Preven t Ifli p ti iurface-fronr touch ing the flat; valve-seat, I fourth, under such; I) ve the'valv'e,

A loose globular valve free, when open, to play between two surfaces a distance apart is impracticable for the present purpose, as it would close the inner glass tube, and thus prevent any liquid from entering the bottle when the siphon-bottle is inverted for filling. In order to vork'satisfactorily, it is necessary that the valve-stem be tight-fitting in its bore,

while the valve must be elastic, so as to adapt itself readily to the valve-scat opening. When the valve is elastic and globular and used in combination with the tight-fitting valve-stein threaded into the spindle E, and surrounded by the automatically-adjustable packing H,

tightening against; the said valve-stem, and

with the spiral spring G and lever I, the pressare "of the said spring (acting in connection with the elastic valve, capable of more yield- .ingor compression than what is necessary to fit it tight against its seat) pushes the lever I always up to its absolute stop in -the slots, so

as to insure the same throw-in depressing it to open the valve. If the valve were not elastic, the fish would be incurred that it would not be held tight'by thespring unless the lever stop short of its-stroke or before reaching the stop in'the slot 8, and consequently it would shorten the downward throw of the lever to that extent, and thus lessen the opening between the valve and its seat.

In Patent No. 182,612, above mentioned, the non-elastic valve used is, to a certain degree,

automatically adjustable by the valve-stem springing sidewise in the bore in whichit is loosely fitted; but in thatcase the packing pinching it between the valve-stem and its bore, while the adjustment of the same inthe spindle E forms'a featuremecessary, in combination with the elastic valve and packing, to

regulate the distance between the valve-seat 1 and the stop for the upper throw of the lever, to'take advantage of the elasticity of the valve -for tightening the same without shortening the upstroke of the lever. o

Havingthus described my invention, what I claim as newQand desire to secure by Letters 7 Patent, is l 1. In a siphon-bottle, the'top 0, provided with the cavity'c, having 'bore for the valvestem,'sid'e' opening leading to the spout,- and circular valve-seat, in combination with the stem e, fitting tightly inthe said bore and carrying anelasti'cwalve fitting the said seat, the self adjusting packing. H, surrounding the said stem.v e,-the spindle E, spring G, and 1e ver I, the said stem e, being adjustable in the .said spindle and the'saidspring acting to tighten the said packing around the stem and to raise the said spindle and valve.

2. The combination of the valve-lever I, the

slotted spindle E, the valve stempacking, and a A. Y
