WILLIAM KOEDDING, OF ST. LOUIS, MISSOURI.
SPECIFICATION forming part of Letters atent No. 747,729, dated December 22, 1903.
Application filed September 8, 1902. SerialNo. 122,477. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM KOEDDING, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Automatic Filling-Machine, of which the following is a' specification.
My invention relates to machines for filling bottles and other receptacles with liquid, and has for its principal objects to produce a filling-machine which will operate automatically when the Vbottle is pressed against it i-n proper position to be filled, to equalize the vpressure in the bottle with the pressure in the supplypipe before the supply-pipe is opened to permit the liquid to How into the bottle, to provide for automatically stopping the flow of the liquid when the bottle is filled, and to prevent any stale liquid getting into the bottle.`
' of a hollow cylindrical thimble or guide 1,
which has a iange 2 on its upper end and projects downwardly through' a hole inthe table or other suitable support 3, to which it V tutes a fulcrum for a lever 6.
is firmly clamped by means of a nut 4, working on a thread on the exterior of said thimble.l Extending upwardly from the flange 2 is an upright or-supporting arm 5, which constithe vertical thimble is a hollow cylindrical slide 7, whose upper end is closed and provided with an arm 8. This arm extends lat-` erally and upwardly and is pivotally connected with the lever 6 at a point about midway between the fulcrunn or seat of thelever and the prolonged axis of the slide. Extending longitudinally throughthe slide is the liquid-supply pipe 9. This supply-pipe/Q is provided with a collar 10, which is ad'justably clamped thereto a suitable distance above the end of the slide. This collar is pivotally connected with the lever 6 by a pin or other suitable means. The pipe 9 is provided with a second collar l1, arranged to move up and Working inl l down inside of the slide 7. This last-mentioned collar 11- forms the lower abutment for a helical spring 12, whose upper end bears against the end portion of the slide 7, surrounding the inlet-pipe. p The lower end of the slide7 is screw-threaded'to` fit into a body-piece 13, which is hollowed out and threaded to receive it. The inlet-pipe 9 extends downwardly a suitable distance 'beyond this body-piece, and the inner edge of its lower end is beveled off to cooperate with an adjustable seat 14 provided therefor. This seat consists of a soft-rubber plug secured in a cap-piece orclosure 15,which is threaded to engage a thread provided there-l for on the end of a tube 16, which is fixed to the body-piece 13 and forms a casing or guide for the supply-pipe 9. This last-mentioned tube 16 has one or more perforations or ports 17 near its lower end in position to be traversed or covered and uncovered. by the lower end of the supply-pipe 9. Surrounding the upper end of the tube 16, where'the tube enters the body-piece, is a cylindrical sleeve 18, which isprovided'with one or more slots or passage-ways 19. These slots or passage-ways 19 extend upwardly from a point below the body-piece to a passage-way 20, arranged horizontally vtherein and obviously may be formed in the body-piece itselfand the sleeve 18 thereby dispensed with. This pas-- sage-way 2O communicates with achamber 21, which is provided with a float 22, adapted to close the port 23 at the top of its chamber. From the port 23 at the upper end of the chamber 31 a passage-way 24 extends to a suitable point for connection to the air-pipe 25. The several passage-ways are preferably drilled in the body-piece 13, and the ends of the drillholes are closed by threaded plugs 26. The port 23 is controlled .by a valve 27, arranged insidel 'of the passage-way 24 and consisting of a plug whose lower edge is beveled to conform to the beveled edge of port 23. Said valve 27 is provided with a rodor stern 28,
rwhich extendsvertically beyond the turn of the passage-way 24 and a stuffing-box 29, provided therefor. This valve-rod 23 .extends IOO 30, adjustably mounted thereon above said lever 6 or the collar 10, and is equipped with a spring 31, abutting upwardly against the same and downwardly against a shoulder 32, provided therefor on the valve-rod 28.
The under side-of the body-piece 13 is pro vided with a soft-rubber washer or ring 33, which surrounds the tube 16 and the sleeve 18 thereon.
The operation of my machine is as follows:V The supply-pipe 9 is connected with the lower portion of the tank of beer or other liquid to be bottled, and the air-pipe 25 is connected to the upper portion of said beer-tank. The bottle 34 to be filled is then placed around the tube 16 with its lip against the softrub ber ring 33. In the normal position of the parts the supply-pipe 9 is closed at its end by means of the soft-rubber plug 14, and the air-pipe is closed by the valve 27. The bottle is forced upwardly against the soft-rub ber ring, thereby sealing the bottle from the atmosphere and at the same time forcing the body-piece 13 and all the parts connected thereto upwardly. The upward movement of the bodyl thus eected is transmitted to the slide 7 and through it to the lever 6, and the movement of the lever carries with it the supply-pipe 9 and the valve-rod 28 and the valve 27. The lifting of the valve 27 from its seat opens the air-pipe, so as to establish free communication between the upper end of the bottle and the upper end of the beertank through passage-ways 19 and 2O and the air-pipe. In this manner the pressure inside of the bottle is equalized with the pressure on the beer in the tank, and consequently when the filling-pipe is open the beer is free to flow by means of gravity without foaming or other disadvantages. The opening of the fi1ling-pipe results from the differential movement of this pipe with reference to its incasing-tube, and consequently such opening requires an appreciable time,whereas the air-valve is lifted directly from its seat. The proper timing of these movements is regulated by shifting the adjustable soft-rubber seat 14 by which the end of the fillingpipe is closed, the adjustable collar 50 on the stern of the air-valve, or the relative positions of the connections to the lever 6 of the fillingpipe andthe stem of the air-valve. When the beer has filled the bottle, it enters the passage-way 20 and through it the Heat-chamber 21 and lifts the ioat against its seat, thereby closing the port 23 and air-pipe 25 and cutting off the flow of beer.
TWhen the bottle is removed, the spring automatically returns the parts to their normal positions. In the returning movement the filling-pipe is closed before the air-valve is seated. Consequently the beer in the passageways of the body piece is forced out and the liability of becoming stale and getting into another bottle is thus prevented.
Obviously the construction hereinbefore described admits of considerable modification without departing from my invention, and I do not wish to be restricted to such construction. So, too, my machine may be used for filling other receptacles besides bottles and with other liquids besides beer.
