APPARATUS FOR FILLING BOTTLES.

SPECIFICATION forming part of Letters Patent N o. 634,793, dated October 10, 1899. Application filed October 29, 189B. Serial No. 694,904. (Alle model.)

To all whom t may concern.-

Be it known that I, WILHELM BACHNER, a citizen of the Germanl Empire, residing at Stuttgart, in the Kingdom of Wrtemberg, Germany, have invented certain new and useful Improvements in Apparatus for Filling Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apport-aine to make and use the same.

This invention relates to improvements in apparatuses for lling bottles and. the like with eervescing drinks, such as beer, from larger receptacles, such' as casks and the like, under the pressure of carbonio acid or air.

As is well-known', when gaseous liquids under pressure are drawn into open vessels a partial escape of the gas takes place-#for instance, in the case of such liquids as contain carbonio acid-owing to trot-hing or foaming. This is avoided in the apparatus which forms the subject of the present invention by theracking or drawingb device, and the vessel to be lled is placed temporarily in commua nication with a vessel standing under pres-` sure by means of movable pistons, so that only a slight difference of pressure exists be tween the vessel to be emptied and the one to be filled. This improved drawing-0R del vice is shown in the accompanying drawings, Figure l being a front elevation of same; Fig. 2, a plan view; Fig. 3, an end view, partly in section.l Figs. t to 6 are separate detail sectional views, on an enlarged scale, of the parts of the apparatus on which the invention is based.

The cask B to be emptied is connected in the ordinary manner4 by means of a backpressure valve b', pipe b, reducing-valve b2,

vand the like with a carbonio-acid container A further tube H is located over the tube G' and carries at the bottom a filling-plu g J for the bottle, said tube H being tightly jointed onto the outside of the tube G by means of a stuiiing-box h and having at the sides a nozlale and a three-way cock 71,' with two small tubular connections. On one of these latter 'a tube 1l is attached, which is connected with a pipe it, situated in a vessel K.

The vessel K is mounted on a bracket K', attached to the frame A of the apparatus and is closed at the top by a cover or cap M, in which a piston m,havin g a rod m', is air-tightly mounted. On the second tubular attachment of the three-way tap h a pipe c' is attached, which leads directly to the carbonio-acid container C, and thus serves at the commencement of the filling of the bottle-that is to say, before any pressure exist-s in the vessel K--to convey carbonio acid directly tothe bottle F.

The bottle F- is placed on a movable bottle-l holder or dish R (normally in an elevated position) after it has been closed by means of the plug J, which dish is fixed on a slide P, which is mounted so as to be vertically adjustable on a slide-bar N by means of two sliding jaws p p' and which is connected with a lever D at the top by means of a chain d'. The lever D is mounted on the plug e of the tap E and is so adjustable. by means of a counterweight ci that when the bottle is placed on the dish R the latter, together with the bottle, sinks or descends and the lever D is turned and the cock E automatically opened. The beer then flows out of the cash B through the pipes c and e', cock E, and filling-tube G into the bottle, while after-the cock h of the filling apparatus has lbeen opened air escapes from the bottle through the pipes H and t and t the pipe To into the vessel K. The air in the latter is thus compressed, corresponding to the pressure of the carbonio acid or the air acting in the cask, and thereby the piston m, located in the cover M of the vessel K, is raised as soon 4as the pressure has reached a certain height. l

Several small openings o are formed in the sides of the cylindrical part O of the cover M at 'an equal height, Fig. 4, through which holes the compressed air can partially escape out of the vessel Kl after t'he piston m has passed said holes, after which the piston 'm immediately descends under the action of a spring-actuated valve m2, arranged at theend of the hollow rod m', and thereby closes the openings o. As soon as the piston "m moves past the opening o there is a sudden outrush- IOO ing-of air from the vessel K due to the excess of pressure in the latter, and thus is there a tendency to the production of a partial vacuum in said vessel, which tendency causes lthe piston to start to sink suddenly of its own weight. The effect of this outrushing of air is usually so great that the said piston would, unless provided against, be lowered with considerable force," and it is for the purpose of preventing this that the valve m2 is employed. This valve is so adj usted by its spring that as soon as the pressure beneath the piston m sinks below the normal the valve is caused to open, and air immediately passes in and through tube m to supply the deticiency ou the under side of the piston. In this way the downward movement of said piston is made easy and gradual, with no tendency lto back pressure either in tube i or the bottle being filled. lVhen the bottle is filled it is raised, together with the lling device G H and the pipe c at'ter the tap h has first been closed. the bottle is automatically closed by the counterweight d on the lever D and on a fresh empty bottle being placed on the dish R is again automatically opened. As soon as an empty bottle has been placed on the dish the tap 7L is then opened, whereby the bottle communicates with the vessel K and stands under pressure in such a way that the beer flowing into the bottle encounters a resistance and any frothing or foaming is avoided. By

altering the weight or' the piston on, the amount of pressure in the vessel K and bottle F may be regulated.

In case of the overflowing of the bottlethat is to say, if the same be removed too late-thebeer passes into the vessel K, and in order to allow of the same being removed therefrom a drawing-off nozzle, with a tap'k and pipe l, is arranged on the same, through which the beer can be run off intoavessel or the like placed beneath, or it may also be drawn oft into any bottle. In the latter case a draw-off tap l', with an air-escape tap Z2, is provided on the pipe Z.

The parts of the drawing-oft apparatus are .attached to the partition-wall A of a stand,

which can be conveniently attached to any racking or drawing-oft apparatus. A hori- Zontal table-plate A is arranged on the lower part of the stand A to allow of the bottles being placed thereon.

I declare that what I claim is- 1. In an apparatus for lling bottles, the combination with a pressure-tank adapted for connection with a cask of beer or the like, of a The tap E on the removal of tap normally closed by a plug orvalve means for connecting said tap with the cask, a movable bottle-holder for. opening said tap by the weight of an empty bottle, means for simultaneously closing the tap and raising the bottle-holder on theremoval ot' the iilled bottle, a filling-tube for the bottle, and a tubular connection between said filling-tube and the tap. n
