SPECIFICATION forming part of Letters Patent No. 729,423, dated May 26, 1903. Application filed November 3, 1900. Serial No. 35,405; (No model.)

To aZZ whom it may concern:

Be it known that we, EUGEN SOHEIBER and EMIL KWAYssER, subjects of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Compression Stop-Cocks and we do hereby declare the following to be a full, olear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention has relation to compression stop-cocks,and more particularly to such stopcocks used on bottles containing effervescent or so called aerated liquids, commonly termed siphon-bottles The invention has for its object a construction of dispensing-head for such bottles provided with a compression-cock so organized and arranged to be adapted for operation by the hand whichholds the bottle, so that the glass to be filled maybe held by the other hand. In order that this may be readily and conveniently accomplished, it is necessary that the device by means of which the compression-cock is operated should be so located as to be in reach of a finger of one hand,while the compression device should be so organ ized as toimmediatelyand automatically close the discharge-duct in the head the moment the device which operates the compressor is released. 7

The compression stop-cock which forms the subject of the present invention consists,,essentially, of an elastic tube with a closing arrangement which under the action of a spring orthe pressure in the vessel containing fluid squeezes party of the pipe, so as to prevent passage of fluid. The arrangement is such that the fluid comes nowhere in contact with metal. v

Figure l of the accompanying drawings illustrates in longitudinal section the application of this invention to an elastic siphonhead, the squeezing of which is eitected by a a spring. Fig. 2 shows the squeezing efiected by the fluid-pressure. Fig. 3 shows, separately, the closing-lever shown in Fig. 2. Fig.

4 is a section of the cock-casing of the siphonhead shown in Fig. 2. Fig. 5 shows a closing of the siphon-head in which a one-armed by a spring '5, so as to force the presser 9 strongly toward a rounded piece m, fixed in the siphon-head.

As shown in Figs. 2 and 5, the pressure in the siphon causes the closure, the lever 72, which is pivoted at n, being acted on by the pressure, so as to squeeze the elastic tube between the two rounded parts at 'm.

t On pressing the lever h the passage at m is opened, allowing the fluid to pass out.

The springs'vl in Figs. 2 and 5 serve only to make the closure at m more certain.

As the fluid nowhere comes in contact with the heada, it may be made of any material, such as cast metal or sheet metal, shaped and put together in halves without requiring tightness against leakage.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is as follows:

1. The combination with a siphon-b0ttle,of a dispensing-head comprising a casing provided with a dispensing-nozzle and a flexible impermeable discharge-tube connected to said nozzle and connectible to the siphon-tube, a compressing member intermediate the inlet and outlet of said tube, a two-armed lever mounted on said head one of its arms bearing on said compressing member and-a spring acting on the other arm of said lever, for the purpose set forth.

2. The combination with a siphon-bottle,of a dispensing-head, an impermeable flexible tube therein connectible to the siphon-tube, means intermediate the ends of the flexible tube operated by pressure within the bottle to compress said tube, and a hand-operated device acting on the compressing means to relieve the tube of pressure, for the purpose set forth.

o. A stop-cock comprising a fiexible tube; a casing-therefor comprising a stationary part and a movable part in contact with said tube adapted to be operated to compress said tube by the pressure of liquid in the tube; and means adapted to move the movable part into position to release the pressure on the flexible tube, substantially as herein set forth.

t. The combination with a siphon-bottle, of a dispensing-head comprising a casing provided with a through-passage and a fixed coinpressing member an therein, a flexible impermeable tube 1) in said passage, a dispensingnozzle fitting into the outer end of said tube and securing it in position, the inner free end of the tube connectiblo to the siphon-tube, a
