DRAFT-TUBE FOR EFF-ERVESCING DRINKS.

SPECIFICATION formi-1g part @fretten Patent No. 65(7),287, dated May e2, 1900.

Application led February 12, 1900. Serial No. 5,000. (No model.)

To ctZZ whom t may concern:

Beit known that I, WILLIAM MAXWELL WHEILDON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of l\Iassachusetts,have invented certain Improvements in Draft-Tubes for Effer vescing Drinks, of which the following is a specification.

Double-stream draft-tubes as heretofore constructed havebeen provided with a rotary valve turning frictionally upon a seat having two openings, one for the large and the other for the fine stream. This form of valve is, however, objectionable, as it soon becomes leaky owing to the wearing away of the leather packing due to the friction produced by its sliding movement around the surface with which it is at all times in contact. These valves alsoA require complicated adjustments to take up the wear and maintain the necessary degree of compression. In another class of lever-operated do uble-stream draft-tubes one of the two streams cannot be drawn without momentarily opening the passage for the other stream, which interferes with the proper operation of the draft-tube. Furthermore, all of these draft-tubes above referred to are so exceedingly complicated as to require a skilful mechanic to take them apart for repairs and again put them in condition for use.

To overcome all of the above-mentioned difficulties and to greatly simplify the construction and reduce the number of parts is the object of my invention, which consists in a draft-tube embodying certain novel features of construction and combinations of parts, as will be hereinafter fully described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a central vertical section of a draft-tube embodying my invention. Fig.l2 is a plan of a portion of the top of the same. Fig. 3 is a sectional elevation on the line 3 3 of Fig. 2. Fig. 4 is a transverse section on the line 4 4 of Fig. l. Fig. 5 is a plan of the bottom of the upper valve-chamber.

In the said drawings, A represents the body or casing of the draft-tube, composed of the portions 10, 11, 12, 13, 14, and 15, screwed to-A gether, as shown in Fig. 1. l

b is the inlet-passage, the inner vertical portion of which opens upwardly into an annular space c, formed between two annular concentric lianges d e, rising from the bottom of the main=valve chamber f and forming the valve-seat, said chamber f having a screwthreaded wall upon which turns a screwthreaded rotary compression-valve B, provided at its bottom with a valve-disk g, of leather or other suitable material, adapted to iit closely down upon the flanges d e, which form the valve-seat to prevent the water` from passing from the inlet-passage b into the valve-chamber. By providing the valvechamber with a double valve-seat composed of two concentric flanges,- as described, the

`water is excluded from the valve-chamber while the valve is closed, thus reducing the liability of leakage.

C is a vertical spindle, by which the valve B is turned to screw it up and down within the valve-chamber f away from or toward its seat, the valve during such movement sliding longitudinally upon the spindle, which is made square in cross-section at that portion of its length or provided with other suitable means, such as a spline or key, whereby it is prevented from rotating independently of the valve, while permitting the latter to slide freely thereupon in the direction of its length. Above the chamber f the spindle is provided with a shoulder 16, against which bears a spiral spring 17, inclosed Within a chamber h at the upper tubular end ofthe portion 14 of the casing, said spring exerting a downward pressure upon the spindle. At the upper end of the portion 14 of the body and located Within the upper open cup-shaped portion 15 is a stuffing-box D, surrounding the spindle C, whereby all liability of leakage from the valve-chamber f is prevented. That portion of the spindle C below the valve-chamber f passes through a vertical opening of somewhat greater diameter than the spindle, leaving van annular space .1c around the same, forming an outlet-passage from the valvechamber, through which when the valve Bis raised the water passes down into a valvechamber m and thence directly into the discharge-nozzle 13 at the bottom of the drafttube. Within this chamber m andurigidly secured to the lower end of the spindle C by means of a nut 'n is a valve 21, provided on its upper side with an elastic valve-disk 22,' which whenthe Aspindle is aised'against'fthe resistance of its spring 17 is brought into contact with an annular seat 23, thus closing the bottom or mouth of the annular passage 7c, through which the larger stream of water'gis drawn into lthe tumbler.- In the bottoml .0L the spindle C is bored a vertical passage q of small diameter forming anez'zlefsaid passage being intersected by a transverse passage-r,

bored-diametrically through the spindle to e meet the annular passage 7c above thefvalve 21, whereby when said valve is closed the wa-4 ter. iscaused to pass in a ne stream and with great force through the vertical passage q directly into the tumbler to stir upits contents and .increase the eiervescence of the liquid as required. y G is a lever-handle havingl its inner end bifurcated and provided with inclined open slots 25, which are hooked Vunder horizontal pins or trunnions 26, projecting from opposite sides of a block 2S, secured to the top of the spindle C, the curved edge 30 ot' the handle resting on a shoulder 31, justY inside'and extending around the top of the cup-shaped portion 15 of the body A, which thus forms a fulcrum therefor, so thata downward pressure`onY the handle G will lift the spindle C against the Ainfluence of its spring 17U andV close the lower valve 21, thus shutting oit the f larger stream, as required, if the mainivalve B has been previously raised by the rotationof the spindle -0, produced bya lateral movement of the lever G. Y

, In operating the draft-tube the handle maybe iirst swung around in a horizontal plane to turn the spindle C and raise the rotary valve B, when the water will iiow freely ina large stream through the annular passage k into the nozzle 13, from which 4it will be discharged into the tumbler beneath, the

valve21 being normally wide open. The handle-G is,- then depressed, closing the valve 21k and shutting oft the large stream, when the water willV be discharged in a fine stream directlyfrom the passage q at the lower end of the Aspindle C into the tumbler, as before described. Ifaine stream only is desired, it will .be seen that it will Vmerely be necessary to depress the handle G before swinging it around in a horizontal plane to open thevalve B.,.when as the valve y21 will then vbe closedgaV fine stream 'only will be produced,thepres s ureon the handle being continued unt-il it isswung back again to close the valve B.

Onthe other hand, if thelarger stream only' is. required, iit will merely be necessary Vto swingtheha-ndle around without depressing it, and7 it will thus be obvious that either the fine or the larger stream may be drawn independently without even momentarily opening the passage for the other stream, which is an advantage in an apparatus of this description, as it avoids waste and produces better results.

. The above-describeddraft-tube, en account of itssimplicity and the ease with which it can be manipulated, greatly facilitates. the operation of drawing eifervescent drinks, Vwhile it is of exceedingly simple construction, having few parts, and can be easily taken apart for repairs and again put in condition foruse without ,requiring the services of a skilled mechanic.
