GAS-VALVE.

Specification of Letters Patent Patented we 16, 1908.

Application filed July 18, 1901. Serial No. 384,340. i

To all whom it ma concern:

Beitknownthat ,ABRAHMJARMOLOWSKY, a subject of the Czar of Russia, and a resident of the city of New York, borou h of Brooklyn, in-the county of Kings and tate of New York, have invented a new and Improved Gas-Valve, ofwhich the following is a full, clear, and exact description.

This invention relates to gas valves adapted to be used with fixtures having a plurality of-branches, each provided with anindividual burner, and has for its object to provide means for turning on or off a predetermined number of burners by a single operation.

Other objects relating to the specific con struction and special arrangement of the several parts of my invention will be understood from the following description and accompanying drawings, in' which drawings like characters of reference indicate like parts throughout the'views, and in which Figure 1 is a perspective view of a device embodying my invention having four branch burners connected therewith; Fig. 2 is a ver tical section of the corresponding device shown in Fig. 1; Fig. 3 is a sectional elevation taken on the line, 33 of Fig. 2; and Fig. 4 is a horizontal section taken on the line 44 of Fig. 2.

As illustrated in the drawings, 1 represents a casing-which may be of .any suitable construction and provided with suitable apertures for a main supply pipe 2 and

branch

3, 4, 5 and 6. The casing is also pro- W I ed with a conical bore 7 communicating" 'W1th said apertures for the main supplypipe and branch pipes, and adapted to recelve a corresponding conical plug 8 having a stem 9 WhlCll engages a sleeve 10 provided with a' finger piece 11, and detachably connected with the stem 9 by means of a screw stud 12. The outer end of the stem 9 may be provided with an ornamental device 13 of any desired construction. A cap 14 is secured to the casing 1 by means of stud screws 15 or other wise, and a spring 16 is arranged between the plug 8 and the inner surface of said cap so as to hold the plug 8 snugly in positionin the recess 7 of the casing. The plug 8 has a hollow interior and the wall of the plug is provided with separateseries of

apertures

17, 18, 19 and 20 respectively, the apertures of one series being spaced from those of each of the other series.

A pointer 21 is connected with the sleeve pipe 5, and another of the

apertures

18, 19

and ZO brought in alinement with the a erture of its respective branch pi en e. the stem 9 is turned farther to the left the ap ertures 17 and-18 are out of alinement with the aperture of their respective branch pipes, leaving only the apertures 19 and 20 m almement with the

branch ipes

3 and 4, and if the stem9 is turned fart or to the left theap- "

ertures

17, 18 and 19 will be out of ahnement with their respective branch pipes, leaving only one of the a ertures 20 in ahnement with the branch p1 es 4. A still farther turn of the stem bring all of the apertures 17 18, 19 and 20 out of alinement with the aperturesof the branch pi es and,

shut off the supply of gas from of the burners connected therewith.' The stem 9 is held by means of the stop 23 against rotary motion to the right beyond where all of the burners engage one of the apertures of the difierent series of the block. As one, two, three or four of the burners are-opened by means of the rotation of the stem 9 and plu 8 connected therewith, the number so opene will be designated by the pointer 21 and the figure or marking of the casing to which it I points, as illustrated in 3.

When it is desired to turn on any particular number of burners, the pointer 21 is made toregister with the desired number on the casing, and the rotation of the plug 8 in turning the pointer to the desired nuifiber bring the the apertures of the proper number of series in alinement with the apertures of the branch p n the construction herein shown and described, the several series of apertures in the plug 8 are arranged in the same horizontal plane. Such arrangement is not essential to my invention, however, and if desired the apertures of each series may be arranged in a dlfierent plane from the apertures of each of the other series.

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

In a device of the character described, the

5 combination with a casing having a main aperture, a series of branch apertures, and a conical central bore, communicating with said main and branch apertures, of a tubular plu engagin the conical bore of said casing 10 am? provide with a multi le series of apertures adapted to register wlth the branch apertures of said casing, the apertures of each series of said plug increasing progressively i1} number, an a stem connected withsaid u p Iii testimony whereof I have signed my 15 name to this specification in the presence of two subscribing Witnesses.
