SPECIFICATION forn'ing` part of Letters Patent No. 660,735, dated October 30, 1900.

i Application filed October 9,-1897.l Serial No. 654,636. (No model.)

To zr/ZZ ich/ont it may concern; j l

Beit known that LJOHN ORMEROD,a citizen ofthe United States, and a residentjof New York, (Brooklyn,) in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Double-Stream Draft-Arms, of which the following is a specification.

This invention relates to soda-water-dispensing apparatus, and has for its object an improvement in double-stream draft-arms which increases their efliciency and simplifies their operation and the making f repairs.

The object is accomplished by the means set forth in the specification and the accompanying drawings, which together constitute a full, clear, and exact description of my inven tion, such as will enable others skilled in the artto which it appertains to make and use the same.

In the drawings like characters refer to similar parts throughout the several views.

Figure 1 is a vertical transverse section sidewise of the arm. Fig. 2 is avertical transverse section through line 1 2 of Fig. l. Fig. 3 is a front elevation of the double-stream Vdraftarm. Figs. 4 and 5 are detailed views relating to the valves.

Referring to Fig. 1, c represents the body of the arm, showing a hollow metallic body divided by the partition Sinto two chambers. A block-tin lining b lines the interior of the shell and completes the divisionof the two chambers. The threaded nut end m screws to the stem of the beverage-connector on the fountain, and the fluids traverse the passages frito the two separate chambers 0 o'. The parts c c' are what I term shells, which contain the valves that give communication between the said chambers o o and the outlets from the arm.

Fig. 2 shows that the outlet from chamber o is through the valve c and the contracted passage Z and from the chamber o is through valve e' and the passage Z. The Valves and the outlets, as shown, are entirely separate from each other,and the valves can be operated only one at a time and are both operated from a single handle. The valves and their containingshells c c are substantially the same as are shown and described in another application taneously with this one for a mineral-water draft-arm and are claimed herein only in their combination with the parts necessary to constitutedouble-streamdraft-arms. Theshells c c' (shown separately in cross-section in Figs. 4 and 5) are screwed into the two chambers 0 0', flanges 3 4 making iight joints with packing, asshown, or without packing. The inner ends of the shells abut against shoulders formed in the liningof the chambers, also V making water and gas tight joints with packing f, as shown, or without packing. The outer ends 5 of the shells, as in Fig. 5, are shaped for the reception of a wrench.

The valves c e' are fast to the inner end of the stems that terminate in the heads d d. The valve ends of the shells c c have their bores enlarged around said stems to the depth of the grooves t, Fig. 4, in their peripheries, the enlarged bores being connected with the said grooves by a hole from the bores to the grooves, as indicated by broken lines in Figs. 4 and 5. rPhe peripheral grooves, with the walls of the arm, form annular openings to the outlets Z l', as shown in Fig. 2.

The valves,'which are wholly contained in the shells c c', are substantially the same as are described in my application for patent for mineral-water heads or draft-arms, the principal difference being 'as follows: y Instead of the valvestems terminating outwardly in knobs for pressure by the hand they terminate in hubs d, that areactuated by the spurs r r, attached to the handlej. The handle j is bifurcated at its lower end and spans the arm and is suspended upon the pivot i, which passes through the solid metal of the arm. The handle arches over the top 'of the arm and spans around the front, as indicated by broken lines in Fig. l and as represented in Fig. 3. Spurs r r on the front span bear upon the heads CZ d, as in Fig. l. These spurs just touch the said heads, and as either gas-pressure or the tension of the springs will keep the valves closed and the heads in the positions shown the handle will be maintained normally in its vertical position. By tilting the handle backward or forward the valves e e' will be alternately opened. Thus for drawing a fine stream having great force the handle would be moved in direction of the for patent made and executed by me simult arrow 6, allowing the iiuid to flow through valve e from the chamber o out through the narrow passage l', and by throwing the handle forward in direction of the arrow 7 valve e would Iirst close, and then valve e would be forced open, allowing the iuid to flow from the chamber o through the valve e into the enlarged passage Z, from which it would ioW in larger volume. When. the handle is released, both valves remain closed. Both valves cannot be opened at the same instant. This arm may be quickly and easilyrepaired. By removing the pivot the handle may be taken away, and the unscrewing of the shells c removes the entire valve mechanism, and the removal of the arm itself becomes unnecessary.

Il do not limit myself to the arranging or construction of the various parts of this arm as herein shown so long 'as the principles of my invention are retained.

Having described my invention, what I claim, and desire to secure by Letters Patent ol' the United States, is-

A double-stream draft-arm for mineral-water apparatus comprising a body containing two valves in the same vertical plane, at right angles to the discharge-nozzle, each valve having a separate and distinct outlet from said nozzle, the said body chambered and threaded to receive the shells containing said Valves, the flanges of the said valve-shells seated upon the outer surface of the said body, lthe inner ends of said shells seated against the soft-metal lining Within the said body7 the stems of the Valves extending through the shells the heads on said stems lying partly within and partly without the spring-chambers in said shells, springs serving the double purpose of closing the valves and retain; ing the packing in the bottoms of said chambers, and a handle pivoted to the sides of said body and having a yoke extending forward and across the front of the body and having projections over and against the valve-heads whereby the valves may be independently operated by the handle, all substantially as herein shown and described.

Signed at New York, (Brooklyn,) in the county of Kings and State of New York, this 17th day of September, A. D. 1897.
