SIPHON APPARATUS.

SPECIFICATION forming part of I etters'Patent No. 643,605, dated February 13, 1900.

Application filed A ril 21, 1899.

to art to which it appertains to make and use the same.

This invention relates to means for filling or partially filling small receptaclessuch as bottles, for example-from a cask or other x larger vessel containing a supply of liquids,

and especially where a series of like small receptacles have a known capacity when filled to a certain height.

In the drawings, Figure 1 shows in elevation the apparatus as it appears in use, al-

though With the flask somewhat lower than it would be held while the liquid is passing. Fig. 2 is an enlarged section through a certain stopper. Fig. 3 is an enlarged detail view of 2 5 part of a certain tube.

In the figures, A represents a cask, and B a small flask or bottle in a plane at some distance below the level of the liquid in the cask. From the interior of the cask to the interior 0 of the bottle passes a tube 0 0, usually wholly or partly of rubber, having at a suitable distance from its lower end an enlargement D in the form of a conical stopper adapted to fit closelyin the mouth of the bottle. In this 3 5 stopper slides a second closely-fitting tube E, of suitable material, normally open at both ends and having marked upon that portion which slides in the stopper a suitable scale or scales FF. Each scale is such as to indicate o correctly the amount of liquid contained in a flask of a given size when the surface G of the liquid in the flask touches the lower open end of the sliding tube. The apparatus being adjusted as shown, air is exhausted from the empty flask through suction at the outer end of the sliding tube, and the liquid in the cask flows over in the tube 0 C, which then acts as a siphon until the liquid discharged semi No. 713,932. on) model.)

in the flask rises to and closes the inner end of the slidingtube, preventing further escape of air-.; The flow is thus arrested automatically, and the siphon being raised for an instant the flask may be removed and replaced by another, and so on. If the tube be-of small bore and such that the liquid will not readily wet its surface, the liquid will not rise within it; but otherwise it will rise to the level of the liquid in the cask. In the latter case the u pwardly-extending portion of the tube must be made longer or the flask 'must be so held that the tube rises above the level in the cask.

The conical form of the stopper of course compensates variations in the form or size of mouths of different bottles. The small tube is usually of rubber, the graduated stem be ing of hard rubber; but where the nature of the liquids makes it desirable other material may be used, and in some cases the tubes are of glass or are lined with glass or coated with paraffin.

For exhausting the air an air-pump H and valve H may be used at the outer end of the sliding tube, and for preventing flow through the siphon while the bottles are being changed a cut-ofi I may be employed, thus obviating the necessity for raising the apparatus.

WVhat I claim is The combination with the stopper having internal upward and downward extensions, of the siphon-tube having its channel extended through said extensions and stopper, a cut off for this tube above the stopper, a normally-open tube passing through the stopper, fittingand sliding therein and having scalemarks to indicate at the surface of the stopperthe capacity of a given flask when fllled to the lower end of said tube, and means for exhausting air from such flask through the tube last mentioned.

In testimony whereof I aflix my signature in presence of two witnesses.
