Tojallwhom it mag conce'r'nf through said neck-portions affording air- Be it knownthat 1, CHARLES F. BRAND, a inlet passages, as will presently be explained. citizen of the United States of America, and In the side or end of the fitting opposite to residentof lVheeling, county of Ohio, and the tube 1. is provided a socketopening 5 60 State of West Virginia, have invented cerwithin which is threaded the neck 6 of a tain new and useful Improvements in valve casing 7, into which leads a gas-supply Valves, of which the following is a specipine 8. A hollow valve stem S'directed into fication. j the casing '7 from the end opposite the neck This invention relates to improvements in 6 carries upon its end a valve 10 which is 65 10 gas-feed valves, and more particularly to a adapted to seat in said casing for closing combined feed valve, mixer and regulator off the gas supply to the mixing tube for gas-burners which is especially adapted through said neck. Said stem 9" has a for use on the burnersof gas-heaters, steam threaded portion or worm 12 in engageboilers, gas'and gasolene engines, carburementwith the interiorly-threaded portion 7 1 ters, and the like. r of the neck 13 of the casing, and a stuffing The primary object of the invention is to box 14 is threaded upon the outer end of provide a gas-controlling and mixing valve said neck 1.3 about said stem. by means of which the gas supply to the Threaded within the neck 6 of the valve burner orburners may be readily controlled casing so as to stand in aline'ment with the 7 5 and wherein the quantity of air admitted valve stem 9 is the rear end of a forwardly for mixing, with the gas is automatically directed nozzle 15 whose front end is taperedincreased and diminished as the supply of and preferably extends to a point within is 1 increased and diminished. the mixing tube 1, as shown.

An appropriate head 19 Figure 1 is an end view of the invention; is provided on the outer end of the needle, Fig. 2 is a sideelevation of the same; Fig. by means of which the latter is adjusted 3 is a longitudinal sectional view of the same with relation to the valve stem 9. 95 taken on the line 3-3, Fig. 1; Fig. 4c is a For controlling the admission of air to side elevation of the vlve stem and come the fitting 2 through the inlet passages, diskplated parts, removegljr m the valve casing; like closures 20 are provided at the mouths and Fig. 5 is an enlarged cross section on of the openings through the neck-portions i the line 5-5, Fig. 3. 3 and at, said closures being adapted for 1.00 Referring to said drawings, in whichlike swinging laterally with respect to said openreference numerals designate like partsfings to increase or decrease their capacity -h h t th Sevemf j fll i di t for receiving air. Said closures are carried the mixing tube, or the tube which leads to by the terminals 21 of arod ,or wire which--\ the gas burners (not shown), which latter is plvotally supported by a pair of loops 105 w i may be of any preferred type. Threaded 22 fixed upon the top of the lit-ting 2. In-

upon'the end of said tube is a socket fitting termediate the loops 22 the wire is bent to 2 somewhat similar in form to a side-openform a crank 23 to which is pivotally com ing ell railing-corner fitting, the neck-pornected one end of an adjusting rod 24 which tions 3 and 4 of which are directed or inlies substantially inparallel alinement with 110 clined downward and outward on opposite the valve stem and has its opposite end enjs sides, as shown, the openings or passages circling said stem at a suitable point, as

between the boss of said hand-wheel 17 and a bearing portion 25 carried by said stem.

As is obvious, when the valve 10 is withdrawn from its seat, allowing an increased volume of gas to be supplied to the burner, traction is made on the crank 23 through the adjusting rod 24, swinging the closures 2O forward and thus increasing the capacity of the openings in the neck-portions of the fitting 2 for receiving air, and vice-versa.

A suitable guide 26 is provided for the rod 24 upon the top of the valve casing 7 as shown.

For indicating the relative amount of gas supplied to the burner, a series of spaced graduations or numbers 27 may be provided upon the top of the stuffing-box 14, and a small indicator 28 carried by the rod 24 at a suitable point will register with said graduations or numbers at different points in the adjustment of the valve.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, a valve casing provided with an inlet and an outletport, a valve seat intermediate said ports, a nozzle rigidly mounted in said outlet portand projected forward therefrom, a valve movable toward and from said seat in alinement with said outlet port, a needle projected forward from said valve through said nozzle and movable with said valve, a hollow member inclosing said nozzle and having air-inlet passages therein, and means associated with'said passages and controlled by movement of said valve whereby the ad-' mission of air through said passages is regulated.

2. In a device of the character described, a valve casing provided with an inlet and an outlet port, a valve seat intermediate said ports, a nozzle rigidly mounted in said outlet port and projected forward therefrom, a valve movable toward and from said seat in alinementwith said outlet port, a needle projected forward from said valve through said nozzle and movable with said valve, a hollow member inclosing said nozzle and having air-inlet passages therein, closures for said passages, and means cooperating with said valve whereby movement of the latter with respect to its seat effects a corresponding movement of said closures with respect to the passages.

3. In a device of the character described, a valve casing provided with an inlet and an outlet port, a valve seat intermediate said ports, a nozzle rigidly mounted in said outlet port and projected forward therefrom, a valve movable toward and from said seat in alinement with said outlet port, a needle projected forward from said valve through said nozzle and movable with said valve, a hollow member inclosing said nozzle and having air-inlet passages therein, closures for said passages, and means interposed between said valve and said closures whereby the latter are moved with respect to the airinlet passages, increasing the air-supplying capacity of the latter as the gas supply is increased, and vice versa.

4. In combination with a mixing tube having a pair of divergently related and laterally facing air openings leading thereinto and means to supply gas to the'tube, a 'closure for each opening, a member secured to each closure and pivotally mounted upon the tube, means to regulate the gas supply, and means for operating said gas regulating means, said last named means being connected to said member to impart corresponding movement thereto upon its actuation.

5. In combination with a mixing tube formed with divergently related and laterally facing air-inlets, of a gas supply communicating with said tube, reciprocable means whereby the amount of gas entering said tube may be regulated, means for controlling the amount of air admitted to said air inlet, and reciprocable means connected to said movable gas regulating means and to said air controlling means whereby movement of the former will be correspondingly imparted to the latter.

6. In combination with a mixing chamber having a side opening air inlet, means for controlling the admission of air through said inlet, a nozzle projecting into said chamber, a gas supply pipe communicating with the nozzle, a valve for controlling said gas supply, a needle valve for controlling said nozzle, means for mounting said valves whereby both are movable in unison and whereby the needle valve may be adjusted independently of any movement of the gas controlling valve, and means connecting the first mentioned valve and the air-controlling means whereby movement of the former produces a proportionate movement of the latter.

In testimony whereof I aflix my signature in presence of two subscribing witnesses.

CHARLES F. BRAND.
