' Application filed July 23, 1903. serial No. 166,783. (No model.)

' To all whom it may concern:

Be it known that LWILLIAM E. Gunsn, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Valves for Vapor-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains-to make and use the same, reference being had to the accompanying drawings, and to the letlers of reference marked thereon, which form a part of this specification.

My invention relates to valve mechanism primarily intended to be used in connection with vapor-stoves of that typein which a single valve is utilized to control a plurality of ated to open the supply to the full extent to certain of the burners of a combination, while the supply to other burners or a single burner of said combination will be open but partially, so that certain of the burners or a single burner will operate at low flame, while other burners will simultaneously operate 'with a flame of normal size.

' Other objects of my invention will appear and the advantages of the same be appreciated when the invention is' fully disclosed. V \Vhile the invention is'susceptible of modification, I have shown in the accompanying drawings and shall hereinafter describe in connection therewith what-is now conceived to be the preferred embodiment of the same.

In the drawings, Figure 1 shows the improved valve mechanisin in sectional elevation. Fig. -2 is a side elevation of the valve proper. Fig, 3is a transverse sectional view,

and Fig. 4 is a diagram, of the valve.

, The invention includes generally a barrel havinga bore,forminga valve-casingdesigned to communicate at one end with the main gasof the same and a hollow valve having a I plurality of radially-directed openings designed to register with said orifices, certain of said openings being arranged'in sets or combinations and certain of the openings comprising the sets being of difier'ent contour from other openings of the sets.

The valve-casing (designated in the accompan ying drawings by the letter a) has a tapering bore 1) and aplurality of orifices a, leading from the latter through the shell of the same, each of which discharges into a nipple (t cast integral with the casing, with which the supplypipes leading to the burners are coupled. One end of the casing is suitably coupled to the pipe or conduit leading from the main gassupply, while-the opposite end thereof is suitably threaded internally for a purpose to be hereinafter described. In the particular exemplification of my invention shown in the accompanying drawings the valve mechanism is constructed to control four burners, and consequently four orifices a are provided.

' The valve working within the casing is designated by the letter Z), is provided with a central bore opening out through one end thereof, and is closed at its opposite end. Through the wall of this valve a plurality of openings 11 lead, which are designed to register with the orifices a as the valve is rotated.

These openings are so disposed that communisaid sets and with each other, so that they.

may be hroughtinto register with the orifices pertaining thereto singly, and one or more of the openings of each set are elongated transversely of the valve in relation to other ori-' fices of the set. Each elongated opening is preferably of substantially the same width as lation to the orifices.

the ordinary openings, but approximately twice the length of the same, and the openings of each set are arranged so thattheir forward or leading edges will be in alinement lengthwise, of the valve.

For manipulatin g the valve the ame is preferably provided with a hand whe l or disk d,

which preferably carries adial provided with indicating characters arranged with i eference to the openings and the casing a is provided with a pointer c, coacting with the dial to indicatethe position of the openings in re The disk d may be secured to the valve and the latter retained in the casing in any desired manner; butthe particular means illustrated in the accompanying drawings for this purpose which constitute asubordinate feature of my invention, has proven to be durable, inexpensive, and highly efficient. As shown in said drawings, a stem f extends axially fromthe closed end of the valve, to,the

outer end of which the disk (1 is attached by a screw pas ing axially through the latter and entering a breaded-socket in said outer end. Loosely mounted upon the stem is a sleet'e h, exteriorly threaded at one end and provided 'at its opposite end with a flange 71., having a milled peripheral edge. \Vhen the valve is inserted inthe casing, the'threaded portion of .the sleeve h isenga gcd with internal threads at the end a of the casing a, and said stem .serew'ed upluntil the end of the latter firmly presses the valve to its seat.

Interposed between theclosed end of the valve, which provides a shoulder about the stem, and the adjaqent end'of the sleeve, which coacts therewith, isa packing-ring or washer i.

.In manipulating theyalve ni'echanisrn the valve is rotated by means of the disk (I, and if it be desired, for instance, to open com-- a through the orifice'which registers with the first-opening while maintaining full communication through the other orifices, the valve is given a slight forward turn, which will-carry said first opening partly out of register with its orifice, while the rear, portions ofuthe other openings will bebroughtinto register with their orifices, andthus only a part of the full supply can pass to one of the burners, while a full supply of gas may pass to the other three. I

The construction and operation of my invention will be. readily understood upon reference to the foregoing description and accompanying drawings, and it will be appreciated that the parts and combinations recited may bevaried within a wide range without departing from the spirit and scope thereof.

Having thus described my invention, what is claimed as new,-and desired to be secured by Letters Patent, is

The combination with a valve -casing havin g aplurality of ports leading therefrom disposed in alinement longitudinally of the ,same, each being in communication with an independent burr-er, of a single plug-valve mounted in the casing for controlling said ports having a plurality of sets of openings arranged in alinement longitudinally of the plug, each set including an opening elongated transversely of the plug and a second opening relatively smaller transversely of the plug than the other, the leadingedges of all of the openings of each set being substantially in alinement, whereby the supply to said ports may be simultaneously opened to the full e tent to any one or any combination of said ports, or partially opened to any one or any combination of said ports, or simultaneously opened to the full extent to certain of the ports, andfbut partially opened to others or a single port, substantially as described.

2. The combination with a valve-casing having a plurality of ports leading therefrom disposed in alinement longitudinally of the same, each being in communication with an independent burner, of a single plug -valve mounted in the casing for controlling said ports having a plurality of sets of openings arranged in alinement longitudinally of the plug; each set including an opening elongated transversely of the plug and a second opening relatively smaller transversely of the plug than theother, the larger and smaller openings of one set being differently disposed from- -the corresponding openings of the other sets,

whereby the supply to said ports may be simultaneously opened to thefullextent to any one or any combination of said ports, or partially opened to any one or any combination of said ports, orsimultaneously opened to the full extentto certain of the'ports, and but par tially opened to others or a single port, substantially as described.
