APPARATUS FOR DRAWING OFF 0R DISPENSING AERATED OR OTHER LIQUID-.

SPECIFICATION forming part of Letters Patent No. 735,867, dated August 11, 1903. Application filed February 4, 1903. Serial No. 141,842. (No model-) To aZ Z whom it may concern.-

Be it known that I, JOSEPH FLETCHER, engineer, a subject of the King of Great Britain,

residing at 73 Narford road, Clapton, Lon

don, England, have invented new and useful Improvements in Apparatus for Drawing Ofi or Dispensing Aerated or other Liquids, of which the following is a specification.

This invention relates to improvements in apparatus for' drawing off or dispensing aerated and other liquids.

According to the invention I provide an intermediate vessel from which the aerated or other liquor is drawn from the main reservoir, the said vessel being provided with inlet and outlet valves and with a snifting-valve, and

also with means, such as a spindle, whereby the said valves can be controlled by their proper sequence by a single operation.

In the accompanying drawings, Figure 1 is a front elevation of a suitable form of apparatus made according to the invention.

Fig. 2 is a plan view thereof. Fig. 3 is a sectional side elevation of the apparatus. Fig. 4 is a section at line 4 4, Fig. 3; and Fig. 5 is a vertical section illustrating the modification in the construction of the apparatus where the latter is designed for dispensing still-liquors.

a is the intermediate vessel or chamber, which is provided with the outlet or deliveryspout b, into which it opens by the orifice b, the said vessel being mounted upon the hollow standard 0, adapted to be secured in any suitable position.

Through the hollow standard a there passes a supply-pipe d, which is in connection at its lower end with a pipe 6, extending from the reservoir containing the aerated orother liquid to be dispensed. This pipe at is in connection with the chamber a through the medium of a passage e, the said passage being, however,normally closed byavalve e, mounted upon a tube or hollow spingle f, extending completely through the pipe cl to the exterior and through the intermediate chamber a, as clearly shown in Fig. 3. This valve 6' is normally held against the seating e by means of the spiral spring f, which is coiled around the hollow spindle f, and bears at its upper end against a collar 9 upon the said spindle and at its other end against a collar g, fixed in the pipe d. V

IL is a hollow spindle which passes through a stuffing-box h, provided at the upper part of the chamber a, the said spindle extending into an internal hollow projection or boss 2' inside the chamber a and having a thread or projection j, which engages an internal spiral groove or thread j, formed in the said hollow boss 2', so that as the said spindle his turned, through the medium of the handle 70, it is moved up and down relatively with the boss 1'. Below the said boss the hollow spindle h is provided with a collar Z, which bears upon the upper end of a spring m, coiled around a sleeve m, attached to a valve m against which the lower end of the said spring 4% bears and which is adapted, as hereinafter described, to close the orifice b to the de-- livery-spout b. The upper end of the sleeve m is formed with an internal lip or flange n and is made with a central hole to-receive a sleeve o. This sleeve 0 is secured to the spindle h and its lower end has a flange 0, which engages the flange n. The aforementioned tube f passes through the sleeves m and 0 and is formed at its upper end with a valve 19, which can be brought against the fixed seating p in the upperend of the hollow spindle h, so as to close the upper end of the tube f, which when the said valve is not closed is in communication with the interior of the intermediate chamberu through the openings q and q in the hollow spindle h and the internal boss t, respectively.

The operation of the apparatus is as follows: Assuming the parts to be in the position shown in the figures-that is to say,with the valve m open-the handle it is turned in the direction of thev arrow, Fig. 2. This. causes the hollow spindle h to movedownward by reason of the engagement of the projection j in the screw-thread j, so that the valve m is closed, the valve e're'maining closed, it being held upon its seat by the spring f. The further turning of the handle it causes the sleeve 0 tomove relatively with the sleeve m (the springm being compressed) and brings the seating 19' upon the valve 10,

so that the communication between the intermediate chamber 0t and the tube fis cut off, and the continued movement of the spindle 7t presses the tube fdownward, and thereby opens the valve e. The pressure in the liquid-reservoir then forces the aerated liquid up through the tube (1 and through the passage 6 into the chamber a. On then turning the handle 7c back the above-described operations take place in the reverse order--that is to say, the valve 6' is first closed, so as to shut 0% communication between the reservoir and the intermediate chamber a, the valve 19 is opened, so as to allow the excess pressure in the chamber Ct to be reduced, an operation known as snifting, and finally the valve m is raised from its seat by the sleeve 0, thereby permitting the contents of the chamber a to discharge through the deliveryspout 19.

Where the apparatus is to be used for dispensing still-liquors, such as beer, I provide an additional valve for admitting air to the chamber a during the discharge of the liquor from the said chamber. This arrangement is illustrated in Fig. 5. The valve-seating 19 instead of being formed at the upper end of the hollow spindle h is provided upon the under side of a hollow plug 9', the upper end of which is made conical, as shown at r, the said conical end supporting the additional valve 8, the seating s of which is formed within the upper end of the hollow spindle h, which end is perforated by the air-passage t. A spring u, disposed inside the hollow plug '1', normally tends to hold the seating 19' from the valve 19.

The operation of this device is as follows: On the turning of the handle 7t in the manner above mentioned the valve m is first closed. The further descent of the hollow spindle h then first closes the valve 5, then the valve 19, and finally opens the valve e, so as to admit liquid to the chamber a, as described. On turning the handle 70 back these operations take place in the opposite order, so that the valve sis opened before the valve 121*, thereby admitting air through the passage 25 into the hollow spindle h to enable the liquid to run from the chamber a when the valve m is opened.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In apparatus for dispensing liquids, the combination with a chamber provided with an inlet and an outlet, and adispensing-nozzle connected to said outlet, a spring-actuated valve normally closing said outlet, a tubular device connecting said inlet with a liquid-reservoir and provided with a valve-seat, a longitudinally-movable hollow spindle extending through said tubular device and through said outlet-valve into said chamber and provided with a valve for engaging said valve-seat, said spindle communicating at its outer end with the atmosphere and at its inner end with the said chamber to form a shifting-tube, a separate longitudinally-movable spindle extending into said chamber in line with said hollow spindle, and provided with a valve for engaging the inner end of said hollow spindle when moved in one direction, operative connections between said second spindle and the outlet-valve for opening the latter when the spindle is moved in the opposite direction, and operating mechanism for reciprocating said second spindle longitudinally, substantially as described.
