ANDREW J. MURSE, OF BOSTON, MASSACHUSETTS.

Letters Patent No. 91,763, dated .Time 22, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may conce/rn: Y

Be it known that I, ANDREW J. Mouse, of Boston, in the county of Suffolk, and State of Massachusetts, have invented 'an Improved Draught-Cock for Soda- Apparatus; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention, suiiicient to enable those skilled in the art to practise it.

In several kinds of soda-water apparatus now in use provision is made for drawing the gas-impregnated water in two streams: first, in aline stream, through a small orifice, to cause, by the force of the stream, a perfect intermingling or" the sirup with the water, and thena large stream, through a broad orifice, for charging the glass as quickly as possible, so that the beverage can be drank before liberation of much of the gas.

My invention has reference to the construction of a draught-cock for drawing soda-water having this provision; and p The invention consists in so constructing the cock that the fine orice, or passage to said orifice, is opened as the handle or hand-wheel of the cock begins to turn, while continuation of the movement of the wheel operates to close the small orifice or passage, and opens connection between the valve-chamber and the large educt-ion-tubc or outlet for delivery of the main body of impregnated water for filling the glass or beverage holder.

The drawings Arepresent a draught-cock mechanism embodying my improvement.

A shows the cock, partly in vertical central section, and parly in elevation.

'B is a vertical, central, and transverse section.

AC is a horizontal section on the line z x.

p a denotes the pipe leading .from the fountain into the valve-chamber, b, in the body, c, ofthe cock, this chamber having a valve, d, pressure of which upon a seat, e, closes both the inlet, f, into the chamber, and the outlet, g, therefrom.

The valve may he loose upon 'a screw-spindle, h, a shoulder, i, or other projection from which forcesthe valve down upon its seat when the screw is turned down, while pressure of the gas-impregnated water forces the valve up, and allows the water to iiow into and from the-valve-chamber when the screw is turned up, thescrew working ina suitable nut-thread formed in the cap k, and being turned by a wheel, l, or other suitable handle. i i

The valve-stem passes through the valve d, and down through a central hole in the body of the" cock; and at its lower end itis connected to another valvestem, n, of a conical valve, o, which is pressed up by a spring, p, against a seat, q, to which its conical valvesurface accurately ts.

has a fluid-passage, u, leading from one side of it,

through, into a ceutml passage, c, made through the spindle mand several {luid-passages, w, leading from its upper or conical surface, through it, into the chamber of thedraught-tube below.

The passage u is in a horizontal plane with an oriiice, x, leading from the valve-seat, and communicating thereby with the valve-chamber b and the valvepassages w are in a horizontal plane with oritices y, leading from the valve-seat, and also communicating with the valve-chamber b.

The valve-stem his bifurcated at its lower end, and the top of the spindle n extends up into the stem h, one or more pins or projections, z, entering the notch or notches at the sides of the stem h, asseen in the drawings, so that, by turning the main valve-stem, the auxiliary valve o maybe turned, as will be readily undei-stood.

Each pin z is` made smaller than the notch which it enters,so'that the valve-stem h may he rotated slightly without imparting movement to the conical valve o.

The operation of the cock is as follows:

When the valve d is pressed down upon its seat e by the screw-spindle or valve-stem h, the valve o is in position to bring the duid-passage, sv, of the conical valve-seat into line with, or so as to open into the passage u, leading, through the valve o, into the central eduction-passage rvwhile each passage y, through the valve-seat, is closed by the surface of the valve, each two adjacent passages, w y, being out of line. .If the screw-spindle is now turned slightly, no movement will be given to the conical valve; but' the starting up of the .spindle enables the valved to be pressed up by the impregnated water, and such water will iiow into the valvechamber b, down around the stem h, into the space back of the valve-seat q, and thence, through the connecting-orifices orpassages u, into and through the central passage c, from whence it willv be driven, in a line stream, with such impetus, as to cause almost instant commingling of sirup, previously drawn into a tumbler, with the sodawater thrown thus into said tumbler-5 and, this mixing having .been eii'ected, the screw-spindle is'rotated a little further, so as to turn the valve o in its seat, cutting oii` the communication between the passages :n u, and bringing each two adjacent passages w y into line, when the soda -1 Water will dow freely, through the valve o, into the chamber ofi, the dramht-tube below, from the large orifice of which it will tlow in quantity, to quickly fill the tumbler, without liberation of the gas.

When the screw-spindle is turned down, the valve.-

passages w, through the conical valve, and the duidpassages fg, of the main valve-seat, will be simnltaneously'closed.

Thus, it will be seen, .that by a very slight turn of' the screw-spindle, the passage is opened for escape of' the'screw-valvc spindle is arranged horizontally with respect to the draught-tube, as shown at D, where the end of the .screw-spindle forms the main valve, and extends through the auxiliary valve, starting back the screw, opening the main valve,` and allowing the soda- Water to escape into and from the valve.- chamber, through a small orice leading through the bottom of the auxiliary valve, into and through a fine tube leading down through and discharging at the bottom of the draught-tube, while,by'tnrning the screwa little further, the auxiliary valve will be turned so as to cut ofi' this fine passage, and open communication between the valve-chamber and a large orice bored through the auxiliary valve, and through a large fluid-passage leading from" the valve-chamber down into the main chamberof the draught-tube.

I claim` a soda-water draught-cock, having a main valve, (l, and an auxiliary Valve, o, controlling inestream and main-stream orifices, both operated by one screw-spindle, when the parts are so constructed and arranged that, rotation of the screw-spindle having opened communication with the fine-stream orifice, continued rotation thereof shuts on" such communication, and opens communication with the large-stream orilces y y, substantially as described.
