UNITED STATES PATENT I 'atented November 10, 1903 Erica SlPH,ON--FILLER.

SPECIFICATION forming part of Letters Patent No. 743,798, dated November 10, 1903.

Application filed November 10, 1902. Serial No. 130,673. (IT model.)

To all whom it may concern:

Be it known that I, HENRY A. ALLWARDT, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Siphon-Fillers; and I declare the following to. be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it pertains to make and use the sarne, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to siphon-fillers, an d.

has for its object an improved fixture to be attached to a tank or barrel which contains aerated fluid and which will enable one to transfer the fluid from the tank to a siphonbottle easily and readily. The fixture itself is intended to be secured to any permanent framework and to be connected to a more or less distant tank by a pipe, and it constitutes work and a siphon-bottle being shown in en-- gagement with it. The parts are shown in the position which they take when the siphon is being filled. Fig. 2 is a longitudinal sec (ion of the valve-casing, the parts being in the position which they take when the nozzle of the siphon is being withdrawn. Fig. 3 is a perspective of the valve, its parts being shown separated.

A is the framework, and B is a tubular coupling secured by a flange (indicated in dottedlines in Fig. l) to the framework A. At the upper end of the coupling B is an internally-screwthreaded enlargement G.

.I is a part of a pipe engaged at.K to the lower end of the couplingB and extending to the reservoir from which the liquid is to be drawn.

D is a valve-casing having screw-threads at its lower end which engages to form a tight joint with the threads of the enlargement G. The interior of the valve-casing D is divided into two parts by a partition 01, through the center of which is a cylindrical aperture.

G is a piston adapted to reciprocate in the upper part of the casing D, in which it is fitted so as to be tight.

H is a cylindrical stem extending from the piston G through the aperture in the partition at. The upper end of the piston G is .The distance along the stem H between the holes 72 and h is so proportioned with refer ence to the thickness of the partition d that there is a clearpassage from the lower chamber through the stem and the piston when the parts are in the position shown in Fig. 1, and there is a clear passage through the piston G between the opposite parts of the chamber in which this piston rests when the nozzle of the siphon-bottle is withdrawn or is withdrawing and the parts are taking the position shown in Fig. 2.

I is a disk or piston secured to the lower end of the stem H and adapted to fit loosely in the lower part of the cavity of the valvecasing D.

E is acap having a centralaperture e. The cap E is adapted to screw on the upper end of the casing D.

N is a rubber washer between the upper end of the casing D and the cap E. The washer N has a central aperture formed through it, audthis aperture may be contracted by screwing down upon the cap E, so as to compress the material of the washer between said cap and the casing D.

h is a valve-seat formed around the stern H upon the inner side of the partition d. The upper surface ofthe piston Iis formed, as by a washer 'i, to seat against the partition 62, as a valve, and to form a tight joint.

M is a siphon, and F is the nozzle thereof.

The method of using the above-described device is as follows: The liquid being under considerable pressure, the piston I being seated against the valve h, as indicated in Fig. 2, the nozzle F of the siphon is passed through the aperture in the cap E and washer N, which forms a tight joint therewith. The end of the nozzle is forced against the piston G, pressing it down to the position indicated in Fig. 1. The end of the nozzle forms a tight joint with the conical surface of the piston G. W'hen said piston is pressed down, it forces the piston I away from its seat, leaving a free passage for theliquid through the pipe J, past the piston I, through the hole h and the aperture, through the piston G and the stem therefrom, through the nozzle F of the siphon, and into the body of said siphon, the siphon-valve being held open,as indicated in Fig. 1.

When it is desired to withdraw the siphon, its valve is allowed to close, and the nozzle F is'pulled out from the cap, the pressure of the liquid and the spring L causing the piston G to follow the nozzle until the piston I partition (Z into the siphon-bottle.

rests against the partition cl. It will be noticed that as the piston G rises a chamber is formed beneath it, into which the liquid from the nozzle F will flow. This chamber is contracted as the nozzle of the siphon-bottle is pushed into place and is practically reduced to nothing when the parts are in the position shown in Fig. 1, at which time there is free communication from thec hamber below the When the nozzle is withdrawn and the parts assume the position shown in Fig. 2, the capacity of the chamber is increased, and there is free communication between it and the nozzle of the siphon-bottle, but no communication between the chambers on the opposite sides of the partition, and at this time the excess fluid that has traveled past the valve I but has not yet entered the siphon-bottle is free to run back into the chamber. The first action on inserting the siphon-nozzle again into the fixture is followed by a pushing back of the piston G, contracting the chamber underneath it 1. In a fixture for filling siphon-bottles, thecombination of a casing, a perforated partition across said casing arranged to form two communicating chambers therein, a pistonstem arranged to reciprocate in the communicating passage, provided with a head at each end, the head at the upper end forming a piston in the upper chamber, said stem being provided with a central longitudinal passage with an opening from said longitudinal passage adapted to communicate with the lower of said chambers, a second opening from said central passage through the stem adapted to communicate with the upper of said. chambers underneath the piston therein, said piston being provided with an opening therethrough, substantially as described.

2. In a fixture for filling siphon-bottles, the combination of a casing having an aperture for the reception of the siphon-nozzle, a reciprocatory piston in the casing arranged to be engaged by the siphon-nozzle, a passage through the piston having an inlet-opening, means for closing the inlet-opening, a chamber to receive the excess of fluid, and means for automatically opening a passage into said chamber, substantially as described.

3. In a fixture for filling siphon-bottles, the combination of a casing having an opening therethrough, a valve arranged to close the opening, a reciprocating piston, a passage connecting the spaces at the ends of said piston, means whereby said passage is open when the valve is closed, and means whereby said passage is closed when the valve is open, substantially as described.

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