FRANK D. GREEN, OF PHILADELPHIA, PENNSYLVANIA.

DOUBLE-STREAM DRAFT-TU BE.

' SPECIFICATION forming part of LettersvPatent No. 696,329, dated March 25, 1902.

Application iiled July 29,1901. Serial No. 70,104. (No model.)

shall be simple in design, of few parts, and

easily operated.

My invention is fully illustrated in the accompanying drawings, in which-'- Figure 1 is a sectional view of my improved draft-tube with the parts in position to discharge the full flow or coarse stream of the liquid under pressure. lar sectional view showing the parts in such position that afine stream may be delivered,

and Fig. 3 is a view illustrating a detail of my invention.

As is well known in dispensing soda-water, two objects must be ,attained in discharging the carbonated water onto the syrup, the first being to draw the water into the glass without disturbing the syrup and the second to discharge a iine stream under full pressure that will pass through the entire liquidcon-y tents of the glass and thoroughly incorporate the syrup at the bottom of the same with the carbonated water. p

In the apparatus which'I have devised a coarse or fine stream may be delivered at the will of the operator by the manipulation ofa single handle, the partial movement'of such handle bringing the parts into such position that the full stream will be delivered, while the full movement of such handle brings such parts into position to discharge ihe'inev stream only.

In the accompanying drawings, 1v represents a valve-chest secured to the end of a supply-pipe 2, such valve-chest havingan opening 3 for the passage of liquid under pressure from said pipe 2. On either side of the opening 3 seats 4 and 5 are provided for the valves 6 and 7, such valves being connected together at 8, the valve G having a threaded extensionl adapted to a threaded Fig. 2 is a simi-v opening in the valve 7. Each of the valves is provided with packing 9, whereby a perfect joint may be made with theirrespective seats.

The valve-chest 1 is closed at the upper end bymeans of a screw-plug 10, having a recess 11, to which the stein 12 of the upper valve 7 is adapted, and in orderv to keep said valve 7 to its seat I provide a spring 13, which is'interposed between the screw-plug 10 and said valve 7. The screw-plug is provided with a squared or heXagonally-shaped head 14,"so that it may be set in place with the aid of an ordinary Spanner-wrench. The valve-stem 12 has a notched top, so that the valves may be readily separated with the aid of a Vscrew-driver.

Surrounding the valve-chest lis a sleeve or casingl, itting said chest and having an aperture 16 at its lower end to receive the reduced end 17 ofthe stem of the valve 6. The said sleeve 15 is secured tothe valve-chest by-means of the screw-cap 18, threaded in the upper portion of the same and carrying an operating-handle 19, pivoted at 19 and having bearing-faces 20. Interposed between the bearing-faces of said handle and the valve chest is a lling-block 21, and when said handle is moved in either direction the sleeve 15 will beraised and the valve 7 lifted from its seat. The connection between said sleeve fand the stem of the valve 6 is such that there "will be no pressure upon-said stem when the sleeve is in the normal position, and the tension of the spring 13 and lthe pressure of liquid-within the valve-chest will be suiiicient to hold the valve 7 to its seat.

vThe lower portion of the sleeve or casing 15 is perforated at 22 for the discharge of the full flow ot liquid when the valves are in the ,positionV shown in Fig. 1, while the stem of the valve 6 has a contracted opening 23 for the discharge of the ine stream, such opening joining a cross-passage 24, which communicates with the interior of the valve-chest when the valve 6 is seated. v

As the upper portion of the sleeve 15 is slotted at 25 to pass the supply-pipe 2, I provide a loose collar 26, which fits said tube and serves to prevent the spreading of the same due to the strain exerted upon it by the handle 19.

The operation of my improved draft-tube is as follows: Under normal conditions the handle 19 is in the vertical raised position,and the valve 7 is tight against its seat, being held thereto by the tension of the spring 13 as well as the pressure of liquid within the valvechest. 'lo cause a coarse stream of liquid to be discharged from the sleeve or casing 15 through the perforations 22 of the same, the handle 19 is moved to the position shown in Fig. 1, opening the valve 7 and permitting a free discharge of the liquid under pressure from the pipe 2 through the opening 3 in the valve-chest. Such stream strikes the Valve 6, which acts as a baille and reduces the pressure of the liquid, so that it may be delivered through the perforations 22 of the sleeve 15 without force. Vhen it is desired to discharge the line stream of liquid in order to stir up the syrup and cause the beverage to foam, the handle 19 is moved to the position shown in Fig. 2, fully opening the valve 7 and seating the valve 6. lVhen this is done, the lower portion of the opening 3 is closed, and the ow of liquid is diverted to the crosspassage 24 in the stem of the valve 6 and is discharged through the contracted opening 23 of said stem. After this has been accomplished the handle may be released and the parts will resume their normal position, the valve 7 being returned to its seat, cutting o the flow of the liquid under pressure.

In Figs. 1 and 2 I have shown a handle 19 having two bearing-faces 20, either of which, depending upon the direction of movement of said handle, may be brought to bear upon the block 2l. In Fig. 3 I have'shown a handle having the bearing-faces 20 and 20". By moving said handle in one direction and causing the bearing-face 20* to engage the said block 21 the casing 15 will be raised and the valves brought to the position shown in Fig. l. Now if the handle is moved in the opposite direction to its full extent, bringing the bearing-face 2Ob in contact with the block 21, the casing 15 will be raised to the limit of its movement and the valves brought into the position shown in Fig. 2.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination in a draft-tube, of the valve-chest having an outlet, a supply-pipe communicating with the valve-chest, a valve controlling the said valve-chest outlet upon one side of the same, means for holding said valve to its seat, a second valve adapted to close the valve-chest outlet from the other side of the same, said valves being xed with relation to each other and havingaconnection whereby the movement of either valve is imparted directly to the other, said connection having a discharge-outlet which is brought into operative position when the second valve is seated, and means for operating said valves.

2. The combination in a draft-tube, of the valve-chest having an outlet, a supply-pipe leading to the valve-chest, avalve closing the outlet from said valve-chest upon one side of the same, means for moving said valve vertically, a second valve adapted to close the outlet from the valve-chest upon the other side of the same, a stem connecting said valves whereby they may be moved in unison, a

sleeve surrounding the valve-chest and in op-- erative engagement with the said valve-stem, and means for raising said sleeve whereby the valve controlling the opening of the valvechest may be raised from its seat, a further movement of said sleeve closing the lower valve.

3. The combination in a structure of the character described, of the valve-chest having a supply-pipe connected thereto and having a suitable outlet therefrom, valves controlling the discharge from said valve-chest and adapted to seat on the inside andoutside of the opening leading from the same, a valvestem connecting said valves whereby they may be moved in unison, said stem projecting below the lower valve, a movable sleeve' surrounding said valve-chest and providing a seat for the end of the projecting valve-stem, and means for moving said sleeve whereby the valve may be operated.

4. The combination in a draft-tube, of the ,valve-chest having an outlet, a supply-pipe communicating with the valve-chest, a valve closing the outlet from said valve-chest and adapted to seat on the inside of the same, means for holding said valve to its seat, a stem carried by said valve whereby it maybe guided, a second valve adapted to close the outlet in the valve-chest and adapted to a seat on the outside of the same, a stem connecting said valves whereby they may be moved in unison,said stem havinga contracted opening and projecting below said lower valve, a movable sleeve surrounding the valve-chest, the lower portion of said valve-stem being in operative engagement with said sleeve, and means for raising the latter, the partial movement of the same bringing the Valves to a midposition permitting the discharge of a full stream of liquid, while the complete movement of said sleeve seats the outside valve against the opening of the valve-chest and permits the discharge of said liquid through the contracted opening of the valve-stem.

5. The combination in a valve structure of the character described having a valve-chest with an outlet for the discharge of liquid under pressure, a supply-pipe communicating with said valve-chest, a series of valves controlling the outlet ot' said valve-chest, said valves being operated simultaneously, a valve-stem having a discharge-opening connecting said valve, said stem also having a communicating through-opening midway of the valves, a movable sleeve forming a discharge-spout operatively connected to the valve-stem, said valve-stem having its discharge-opening beyond said sleeve,and means for moving said sleeve whereby the valves may be operated to discharge the liquid from ICO TIO

the valve-chest, the partial movement of said sleeve opening one valve and permitting the passage of the liquid from the valve-chest to the sleeve and thence from the openings therein, while the further movement of the sleeve closes the outlet from the valve-chest and causes a discharge of the liquid through the contracted opening in the valve-stem.

G. The combination in a valve structure of the character described having a valve-chest with an outlet, a series of valves controlling said outlet, a valve-stem connecting said valves and having a contracted opening therein, projections extending from said valves in line with the valve-stem, the upper projection serving to guide the valves, while the lower projection is provided with the contracted opening communicating with the portion be-V tween the valves, a spring' for holding one of said valves to its seat, a movable sleeve surrounding the valve-chest and engaging the depending portion of the valve-stem, and means for imparting vertical movement to said sleeve whereby the valves may be operated, said valves moving in unison by the move-V ment of said sleeve.l
