REGULATlNG-VALVE FOR GAS-BURNERS.

EPECIFICATION forming part of Letters Patent No. 348,897, dated September 7, 1886.

(No model.)

To all whom it Huey concern:

Be it known that I, MILLARI) F. ELLIOTT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Check or Regulating Valves for Gas Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of my invention is to provide an efficient and inexpensive device for regulating and controlling the How of gas to a gasburner; and my invention consists of theparts and combination of parts hereinafter de scribed.

In the drawings, Figure l is an elevation, partly in section, of a gas-burner and part of bracket embodying my invention; and Fig. 2 is a plan of the valve.

A is the gasburuer, which may be or any of the well-known forms; 13, bracket; 0, a thin]- ble provided with threads by means of which it may be screwed onto the bracket 13 and burner A.

D is a chamber within thimble C; E, a valve within chamber D; F, a stem extending down ward from valve E; G, a gas-passagein bracket B, in which stem F works.

The direction of the gas is shown by the arrows. It passes up the vertical passage G and enters hollow valve-stem F, enters valve E, escapes from this valve through slots a, enters chamber D in thimble O, and passes through an opening, I), in thetop of thimble O, and passes from thence to the burner. The

valve E has a seat against the top of bracket B, and this valve is made of very thin mate rial. The valve E during its movements is kept i n a vertical position by the valve-stem F. Should the pressure of gas become too great, the valve E is lifted, and is forced against the top of the chamber D. The top of the valve E is conical, and the apex of this cone enters the hole b, andan y further increase of pressure forces valve E tighter against thetop ot' chamber D, and as the valve E has very thin sides and top the slots a will be pinched together or closed to an extent corresponding to the pressure, and the tlow of gas through hole b will be practically the same at all pressures. At very low pressures the valve E falls, and then the gas escapes through all the slots a and passes through hole I) to the burner.

Instead of the valve-stem F being a hollow rod, it may beasolid postof less diameter than the vertical passageG, and thebottomof valve E in this case would be perforated, in order to allow the gas to enter it.

Having thus described elain1- The combination, in adevice forcontrolliug my invention, I

the flow of gas to a burner, of the bracket B, i

with vertical gaspassage G, thimble O, with opening I), valve E, with conical top and slots (1, valve-stem F, thimble (J, with chamber 1) and opening b, and burnerA, allsubstantially as set forth.
