SPECIFICATION forming part of Letters Patent No. 721,547, dated February 24;, 1903.

Application filed January 10, 1902. Serial No. 89,106. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. EARL,a citizen of the United States, residing at Detroit,in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Siphon-Fillers; and I do 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 appertains to make and use the same, reference being had to the accompanyingdrawings, and to the fig ures of reference marked thereon, which form a part of this specification.

This invention relates to a device for filling siphon-bottles and similar receptacles with carbonated water and other liquids under pressure, and it consists in the construction and arrangement of partshereinafter fully set forth, and pointed out particularly in the claims. u

The object of the invention is to provide simple and efficient means for maintaining the siphon-bottle imposition, so that the liquid under pressure may be directed into the nozzle of the siphon and the valve of the siphon opened at the same time to allow the water to flow into the bottle. A further arrangement provides for a relief-opening which allows the liquid and gas occupying the channel between the controlling-valve and the siphon-nozzle to escape when the controlling-valve is closed, thereby preventing the escape of gas and water at the nozzle of the siphon when the siphon is removed after the bottle has been filled.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is an elevation showing my improved apparatus and a siphon-bottle in position for filling. Fig. 2 is a longitudinal section through the coupling and controllingvalve, showing the position of parts when the fluid under pressure is being directed into the siphon-bottle. Fig. 3 is a transverse section as on line 3 3 of Fig. 2. Fig. Lisa sectional View similar to Fig. 2, but showing the controlling-valve in position to cut off the flow designates the siphon-bottle,havin g the usual spring-controlled valve provided with the projecting stem 2,adapted to be actuated through the lever 3 to open the valve. A bracket lis attached to the under 'side of a bar or counter (indicated by line 5 in Fig. 1) andis provided with a clamp 6, which embraces a coupling 7 and supports said coupling in position. Pivoted at 8 to the bracket 4 is a lever 9, adapted to bear upon the upper end of the valve-stein 2 when the siphon-bottle is in the position shown in Fig. 1. Projecting from the rear of the coupling 7 is a threaded boss 10, adapted for attachment to a pipe leading from the pressure-reservoir (not shown) adapted to contain thecarbonated water or other liquid under pressure. Opening through said threadediboss 10 is an intake-port 11, which passesinwardly and downwardly and opens into a socket formed in the lower end of said coupling. Also communicating with the socket in the lower end of said coupling is a passage-way 12, which terminates in a nipple 13 at the couplings upper end. Surrounding said nipple within an annular recess at the end of the coupling is a compressible washer 14.

Located within the socket at the lower end of the coupling is a compressible gasket 15, having openings therethrough which register with theintake-port 11 and the passage-Way 12, respectively. Seated in said socket is a rotary plug-valve 16, havingin the face thereofthe inwardly-extending openings 17 and 18, connected at their inner ends by the transverse channel 19, whereby a continuous passage is formed through the valve by way of said openings and channel. Screwed into the outer threaded opening in the recess at the bottom of the coupling is a plug 20, which surrounds the stem 21 of the valve 16 and 2, communication is established between the intake-port and the passage-way 12 by way of the valve 16.

When desiringto fill the siphon-bottle, the nozzle 23 of the siphon is placed over the nipple 13 and against the compressible washe 14, surronndingsaid nipple, as shown in Figs. 1 and 2. By a downward pressure upon the lever 9 the valve-stein 2 is depressed to unseatthe sighon-valve and at the same time force the siphon-nozzle onto the washer surrounding the nipple 13, thereby making a tight coupling between said nozzle and the discharge end of the passage-way 12. The valve 16 is then opened or turned to the position shown in Fig. 2, when the fluid under pressure will flow through said valve and through the nozzle of the siphon in the bottle. When the bottle has been filled, the flow of liquid is cut off by closing the valve or ro tating it so as to carry the apertures 17 and 18 therein out of alinement with the intakeport 11 and the passage-way 12, which position is shown in Fig. 4. To provide for an escape of the fluid contained in the passageway 12 when the valve 16 is closed, said valve is provided with a discharge-opening 24, which extends inwardly from the face of the valve and thence diametrically thereof between the openings 17 and 18, its discharge end passing through the side of the valve and communicating with the relief-port 25, passing through the wall of the coupling, whereby all gas and water under pressure contained in the passage-way 12 finds immediate escape, enabling the siphon-bottle to be removed from the coupling without spurting or sniffing as the nozzle is withdrawn from the nipple 13. It will be observed that the arrangement is such as to cause the discharge-opening in the valve to register with the passage-way 12 only when the valve is closed to cutoff the flow of liquid through the port 11 and that when the valve is open to allow the liquid to flow into the siphonbot-tle the discharge-port in said valve is out of alinement with said passage-way 12, as shown in Fig. 3.

For the purpose of supporting the bottle firmly in position when placedon the coupling for refilling an inclined plate 26 is screwed onto the lower end of the coupling and secured by a jam nut 27, the downwardly-extending end of said plate being concave, as at 28, to receive the round of the bottle and maintain it in position while being filled.

It will be observed that in this apparatus the controlling-valve does not depend upon the action of a spring to close it, therefore obviating the failure of the valve to close through a weakening of the spring or the accumulation of some substance upon the valveseat. It will also be observed that simultaneously with the closing of the controllingvalve a relief is provided for the fluid under pressure remaining in the passage-way 12, so that an escape of fluid at the nozzle of the siphon is obviated as the bottle is removed from the coupling.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a siphon-filler, the combination of a stationary coupling having an intake-port adapted to be connected with a source of fluid under pressure and having a passage-way extending from end to end of said coupling, a member at the terminal of said passage-way adapted to receive a siphon-nozzle, a controlling-valve in said coupling adapted by its movement to connect the intake-port with the nozzle of the siphon through said passageway, a relief-port through the wall of the coupling, and a discharge-opening in said valve adapted to connect the passage-way leading to the nozzle of the siphon with said relief port when the controlling valve is closed.

2. In a siphon-filler, the combination of a coupling, an intake-port in said coupling connected with a source of fluid under pressure, a passage-way through said coupling, a nipple at the terminal of said passageway adapted to receive a siphon-nozzle, a valve in said coupling provided with an opening adapted to connect said intake-port with said passageway, a discharge-opening in said valve, a relief-port in the wall of the coupling, said discharge-opening being adapted to connect said passage-way and nozzle with said relief-port in the wall of the coupling when the valve is closed.

3. In a siphon-filler, the combination of a coupling, an intake-port therein connected with a source of fluid under pressure, a passage-way through said coupling, an external nipple at the discharge end of said passageway adapted to receive a siphon-nozzle, a compressible washer around said nipple, a valve adapted to establish communication between the intake-port and said passage-way, a reliefport through the wall of the coupling, and means operated upon the closing of the valve for connecting said passage-way with the atmosphere through said relief-port.

In testimony whereof I sign this specification in the presence of two witnesses.

CHARLES M. EARL.
