DOUBLE-STREAM DRAFT-ARM.
Specification of Letters Patent.
Patented July 5, 1910.
Application led April 16, 1910. Serial No. 555,926.
This inventionhas relation to doublel stream draft arms for soda fountains.
The object of the invention is to provide the use of washers and packings at parts through and about which the fluid flows.
Another feature is the use of ground joints whereby the wear of the parts is reduced to a minimum; and the arrangement whereby access may be readily had to the various parts for the purpose of cleansing and inspection.
Finally the object of the invention is to provide means of the character described that will be strong, durable, eflicient, and easy of operation, simple and comparatively inexpensive to construct, and also in which the several parts will not be likely to get out of working order.
W'ith the above and other objects in view, the invention has relation to certain novel features of construction and operation, an example of which is described in this specification and illustrated in the accompanying drawings, wherein:
Figure 1. is a vertical sectional view of the arm, Fig. 2. is a front elevation, Fig. 3. is a transverse section of one of the conical shells, Fig. 4. is a similar view of the other shell, and Fig. 5. is a detail in section of the shells removed from the head.
In the drawings the numeral 1, designates a bracket sleeve which is adapted to be attached to the soda fountain and connected with the source of fluid supply. At its outer end this sleeve is threaded into the rear side of a head 2 at the central portion thereof and communicates with diverging passages 3 and 4 formed in the head. These passages terminate respectively at the rear chambered portions 5 of tapered and conical bores 6 and 7 extending transversely inward in the head from the front side, and arranged one above the other. These bores taper inward and their peripheries are ground to a line degree. At their rear ends, each bore is provided just r forward of the chamber 5, with internal and projecting screw threads 8. An elongated valve shell 9 is tapered to lit snugly in the bore 6, while a similar shell 10, shorter in length is fitted in the bore 7. These shells are each provided at their rear ends with a counter-sunk screw threaded portion 11 adapted to engage the threads 8 whereby the shells are fastened in the bores. These shells also have their peripheries ground to frictionally engage the peripheries of the bores and form gas and water tight joints. The face of the head is formed with a vertical iat portion 12 with which the outer ends of the shells terminate, iush. Each shell has a central longitudinal and cylindrical opening 13 extending from its forward end and terminating at the forward end of a smaller opening 14 which latter terminates in a conical valve seat 15 at the rear end of the shell. A conical valve 16 engages in the seat of the shell 9, while a similar valve 17 engages in the seat of the shell 10. The seats as well as the valves are ground so that when the valves engage the seats the passage of iiuid into the openings 15 from the chambers 5 will be prevented and an efficient cut-off pron vided. From each valve, a valve stem 18 extends forward through the openings 13 and 14, passing through and snugly fitting a packing 19 preferably of soft metal and disposed at the intersection of the openings 13 and 14. These packings are the only ones used in the entire construction. Each stem 18 is surrounded in the opening 13 by a coiled spring 20 bearing against the packing at its inner end and impinging the inner side of, a cap 21 threaded on the outer end of the valve stem. The caps 21 project from the ends of the shells and a portion extending into the openings 13. It is obvious that by pressing either cap inward, the valve is moved inward and unseated permitting the fluid from the chamber 5 to pass into the opening 14. The means for depressing the caps will be hereinafter described.
The two valves and shells are, one for supplying a sharp stream and the other for supplying a spray stream. The shell 9 and valve 16 control the sharp stream, while the shell l0 and the valve 17 control the spray stream. Intermediate the ends of the opening or passage 14, a port 22 ex* tends transversely through the shell 9 to a circumferential duct 5() in the periphery which registers with a passage 23 extending through the head to the lower end, the passage being offset to avoid the passage 4. At the lower end of the passage 23 a draft sleeve 24 is screwed into the head. This sleeve has 'a central passage 2 5 registering with the passage 23 and this passage 25 is continued in a discharge tip 26 screwed'into the lower end of the sleeve.` The tip 26 carries a perforated cup 27 fitting up close against the Vsleeve and through which the spray upto the bore 7 of the shell 10 where it reg'- isterswith a peripheral duct 32 formed on 'the shell. From the opening or passage 14 lof the shell 10 a plurality of radial ports 33, as'V shown in Fig.v 4, extend transversely through the shell tothe duct 32, permitting the passage ofthe fluid in a greater quantity than the single port of the shell 9.
' For alternately depressing the valve stems andunseating the valves, a handle 34 is pivoted on the head 2 by trunnion screws 35. The handle comprises a' yoke member 36 -normally disposed horizontallyA about the central front side of the head. At its central portion the yoke Vmember has a boss 37 provided on its inner side with rounded recesses 38Y receiving the caps 21. These recesses as well as the caps are disposed above and below the horizontal center of the head on which the handle is pivoted; thus by pulling thehandle forward, the valve 17 will be depressed and the spray stream given from the nozzle, while by pushing the handle rearward,the valve 16 isrd-epressed and the sharp stream given from the nozzle.
It will be observed that only a slight movement of the handle is necessary to depress the valves as they need be only moved a short distance to Vpermit a free passage of the'fluid. While the springs 20 will return the valves to their seats, the pressure yof the fluid against vthe valves will hold them in their seats and obviate leakage.
