AMANDUS C. ROESSLEB, OF MINEOLA, AD WILLIAM A. ARMINGTON, OF NEW YORK, N. Y., ASSIGNORS T O B AY STATE GAS COMPANY (DELAWARE)- A CORPORATION OF DELAWARE.

To all whom t may concern.' I

Be it known that we, AMANDUS C. RoEss` Y LER, a subject of the King of Great Britain and Ireland, formerly of London, England, and now a resident of Mineola, Nassau county, and State 'of New York,and TIL- LIAM A. ARMINGTON, a citizen of the United States, and resident of thel borough otI county of Kings', city and State' Brooklyn' of New JYork, `have invented certain new and useful Improvements in Gas Systems, of which the following is a specification.

Our invention relates particularly to those gas systems wherein a pilot light or pilot, as it is called, is used for igniting the burner.

To be effective in lighting the burner, it

has been necessary heretofore to place the" 'pilot to throw a flame directly-"against'the this cross tire against the already heatedburner. Where the burner is in the form of an inverted mantle, itwill be evident that mantle will have a very injurious ee'ctl.,

The principal object of our invention is to overcome these various objections.

To this end our invention consists in placing the pilot a considerable distance away from the burner lso as not .to be .injured by the heat vof the burner, and in providing l so as totdirect the iame issuing therefrom,

ltoward the; burner, and it is furthermore disposed far enough away'from the burner so means for Aadmitting an excessive flow of fuel to the pilot just as the burner is turned y on, so that under this greater impulse the .flame from the pilot will bridge the distance l .cause ignition between pilot and burner and at the burner.

Ina preferred form the :means for`con: trolling the flow of gas to the pilot consistsl of certain valve'mechanism embodying in part a rotaryv valve body Ahaving passages j which when the. valve body is operated to turn on flow Ato the burner, will permit an excessive flow to the pilot, and will, as the flow to the burner is turned all the way on, finally cut 0E the pilot entirely.

Another feat-ure of our invention, when the same is used in connection -with a preseas SYSTEM. Y

means for simultaneously cutting off both the flow of the air and the gas. The means for accomplishing this purpose may be a part of that same valve mechanism which controls the pilot.

Various other objects and features of our linvention will appear as the specification proceeds.

Wye have illustrated in the accompanying drawings, a preferred embodiment of our invention, but we would have it understood that various changes and modifications may be made therein without departing' from'the spirit and scope of theA invention.

the drawings: Figure 1 is a side eleva-- tion of our invention with certain of the pipe connections broken away and shown in sure-gas system, consists in the provision of section. F ig.'2 is a broken detail view look- 'ing in the direction of the arrow 2 in Fig. 1.

Fig. 3 is an enlarged sectional view of the valve mechanism, this view being taken .With

the rotary valve body in the position indi- `cated in Fig. 4. Figs. 4:,*5- and Aare detail sectional views illustrating the operation of the valve. Fig. 7 is a detail view of a slight modification of the valve mechanism. y

Like reference characters have beenused to designate like parts throughout the several views. l V L For purposes of illustra-tion. "-we have shown our-inventionl as applied to a pressure-gas'sy'stem in which the burner 1receives a supply of mixed air and gas from 'the air and gas conduits 2 and 3 respectively the gas and air-being properly comminglod in amixi chamber 4, before `reaching the burner. T e .pilot 5 is, as shown, disposed asnot to -loe injured by the heat of the burner; This 'distance may vary but it is y preferablysuchfthat when somewhat more than the usual flow of gas is admitted to the pilot, the iiame from the pilot will just reach to the burner. The pilot is supplied'with gas throughl a pipe ortube 6. v

In its preferred form t'he valve mechanism consists of` a valve 'casing 7, with a valve body 8, rotati'vely engaged therein.' f The extending in one direction only from the opposite end of the main passage, whereby when the Valve body is rotated to bring the main passage into a'linement with thefconduit,`-` an` additional volumeof-gas will rst" besupplied to the pilot, after which ther pilotv connect-ion will lbe closed.

The combination with a burner, of air duits in line with the air and gas connections respectively, a single angularly disposed pilot connection leading from :thev

side of the gas conduit to a pointl adjacent the burner, a single rotatab e valve bodyr journaled in the valve casi-ng and intersectheyalve casing angularly offset c burner "inf advance of the air,"acirvalve body`,' iiitersecting one end ofthe inain gas passage* therein 'and extending in. opposite V v gas'condut and pilot when iow tothe burner is cut o and to provide communication from the main gas passage to the burnerl and an increased flow to the pilot when the valve is rotated to start the burner, and a secondv circumferentially arranged groove in the valve body extending from the opposite end of the main gas pas- ,sage therein only in the one direction toward the pilot, whereby to open up iow to the niain gas passage when the valve vbody is' in the intermediate position with `flow of gas von toboth t-he burner and the pilot, and

lthetvvo grooves in the surface of the valve body terminating short of each other so that the valvef'body will cut of 'flow to the pilot when the main gas passage therein is in line with the gas conduit.
