BARREL CHARGING OR DISCHARGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 553,709, dated January 28, 1896. Application filed July 13, 1895. Serial No. 556,853. (No model.)

To all whom it may concern:

Be it known that I, EDGAR FRIEDMAN, a citizen of the United States, residing at Dobbs Ferry, county of estchester, and State of New York, have invented certain new and useful Improvements in Barrel or Package Ohargin g or Discharging Apparatus, of which the following is a specification.

My invention relates to apparatus for use in charging into or discharging from barrels or other packages fermented, carbonated, aerated, saponaceous, or any effervescent liquid with the object of producing an even fiow and preventing frothing, foaming or a disturbed condition of the liquid.

I have found that by releasing the pressure upon the liquid within thefilling or discharging pipe immediately before the liquid flows into the receptacle into which it is being charged and preventing the escape into the package of the unassimilated or free gases from the beer the foaming and frothing are greatly lessened. To release the pressure, I gradually increase the size of the dischargepipe of the apparatus at the discharge end, and to prevent the escape of the unassimilated gases I cover the discharge-openings with a fine wire-gauze. I find also that by placing a small ball immediately at the outlet of said pipe in the direct path of the current of liquid and rounding the inner surfaces of the dis charge-opening over which the liquid passes the frothing and foaming of the latter are almost entirely prevented.

In order that my invention may be fully understood I will first describe the same with, reference to the accompanying drawings, and afterward point out the novelty with more particularity in the annexed claims.

In said drawings, Figure I is a front elevation of my improved apparatus, showing it in position in a barrel. Fig. II is an elevation of the same, partly in section, looking at the left side of Fig. I.- Fig. III is an enlarged detail sectional view of the discharge end of the discharge-pipe. Fig. IV is an enlarged detail view of the three-way valve. Figs. V

and VI are respectively a side elevation and section of the discharge end of the pipe having the wire-gauze covering the outlet.

My improvements are applicable to any place in which a liquid liable to foam is to be charged into or discharged from a receptacle.

In said drawings, 1 is a flexible hose adapted to be connected with a vat from which the liquid is to be drawn and having its end coupled at 1 to the end of a bent pipe or gooseneck 2, which is screwed into the upper end of the valve-casing 3. Valve-casing 3 has screwed into its other end the discharge-pipe 6o 4, which slides freely through a head 5 and is provided with a lower expanding end having side discharge-openings.

' The head 5 carries a packing 5 near its upper end, which closely surrounds the pipe 4 and is confined by a; threaded follower 5". The lower end 5 of the head 5 is reduced and screw-threaded to receive the tapered rubber bushing or bung 5, which latter is adapted to fit snugly in the bung-hole of a barrel or other package to be filled. The head 5 also has handles 6 projecting from its opposite sides, by means of which it can be easily lifted from the barrel by hand. A counterweight 7 attached to the end of a cord 8, which 7 5 runs over pulleys 9 and is attached to the goose-neck 2 by a hook 8, serves to balance the weight of the apparatus to facilitate inserting it and removing it from the barrel.

10 is a three-way valve-plug seated in the So casing 3 and having a liquid-passage directly through it and an air-passage extending from one side into the liquid-passage. The passage directly through the barrel-plu g allows the liquid to flow freely through the pipe 4 when in the position indicated in the drawings; but when turned at right angles the fluid-passage Will be closed and the portion of the discharge-pipe 4 below the valve-casing will be placed into communication with 0 the air-inlet 11. The air-inlet is closed when the liquid is flowing into the package.

12 is an annular chamber or hollowed-out portion in the lower end of the head 5, which surrounds the discharge- pipe 4, and 13 is a 5 vent leading from said annular chamber up into a sight-tube or gage-glass 15, which is supported directly in front of the head 5 by means of the tube 13 at its lower end and the projection 14 at its upper end.

25 is a three-way coupling-pipe coupled to the upper end of the tube 26 leading from ICO the gage 15 and having a flexible air-tube 27 coupled to its upper end.

28 is a branch of the coupling-pipe 25 connected by flexible tube 29 to the air-inlet 11.

The liquid-passage is somewhat enlarged downwardlythat is to say, the pipes 2 and 4, with the passage through the valve-easin g 3, are slightly larger in diameter than the hose 1-and at the bottom the discharge-pipe 4: is still further expanded into a flaring discharging end 16, which is preferably separately formed and applied to the end of the discharge-tube by a suitable screw-thread 16. The structure of the lower flared end of the discharge-tube is clearly shown in Figs. I and III of the drawings. It is formed with side openings 1 7, the rounded bottom. portion 17, and is provided with a hollow ball 18, which is centrally confined upon the headed pin 20.

The ball 18 is allowed to rise slightly upon the stem 20 under the action of the discharging fluid.

I prefer to form the side openings 17 of oval shape extending crosswise of the tube, and I form the edges of the opening tapered or rounded, in order that the discharging liquid will only come in contact with the rounded surfaces and have its passage facilitated.

To further insure against the frothing or foaming of the aerated liquid passing through my apparatus I prefer to cover the side openings 17 with a wire-gauze 30, which may be screwed in place by any suitable meanssuch, for example, as shown in Figs. V and VI of the drawings. I have experimented with this wire-gauze over the outlet-openings of the discharge-pipe and find that itis a great addition to the apparatus, as it appears to confine the free or unassimilated gases within the discharge-pipe and prevents the foaming and frothing of the liquid.

The liquid entering the apparatus willhave its pressure released on entering the pipe 2,

and the pressure will be still further taken off as the liquid enters the flaring part 16 of the pipe, and when it impinges against the ball 18 it will flow smoothly around the same and out through the passage 17 without frothing or foaming.

As the package fills with liquid, there will be considerable back-pressure within the package, as the bung-hole is tightly closed by the head and the vent 13 is of small diameter compared with the supply-pipe 4E and the liquid is charged into the package under pressure. \Vhen the package is full, a small quantity of beer passes up through the chamber 12 and vent 13 and appears in the gage-glass 15. The valve is now turned down, stopping the further flow of liquid and opening the air-inlet 11, so that when the workman raises the apparatus by means of the handles 6 the air will be allowed to flow in through pipes 27, 25, 28 and 29 to vent 13 and down through the pipe 4, clearing the same of liquid, which enters the package in sufficient quantity to fill the space which was occupied by the apparatus. Air also passes from pipe 25 down through gage and empties it of liquid.

As the pipe a slides freely through the head 5, it maybe slid down after the head is in position 011 the package until it rests upon the bottom of the same. The apparatus is thus applicable to packages of any size.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In an apparatus for charging liquid into, or discharging it from, a barrel or other package, the combination of the expanded dis charge-pipe 4 increasing in diameter toward its discharge end, the three-way valve 10 and Valve-casing 3, the latter having air-inlet 11, the liquid- supply pipes 2 and 1, and the bungfitting head 5 wherein the pipe 1 freely slides and having the vent 12, 13, substantially as set forth.

2. In an apparatus for charging liquid into, or discharging it from, a barrel or other pack age, the combination of the discharge-pipe increasing in diameter toward its discharge end and formed with discharge-openings in its side, and the ball placed within the discharge end thereof, substantially as set forth.

3. In an apparatus for charging liquid into, or discharging it from, abarrel or other package, the combination of the expanded discharge-pipe 4 having outlets 17, the ball 18 and headed stem all arranged and adapted to operate, substantially as set forth.

a. In an apparatusfor charging liquid into or discharging it from a barrel or otherpackage, the combination of the discharge-pipe having expanded discharge end, a ball confined within the discharge end, side openings in said discharge end, and wire net or gauze covering the openings, substantially as and for the purpose set forth.
