JAMES A. MARSH, OF CLEVELAND, OHIO.

VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 358,284, dated February 22, 1887.

Application filed September 13, 1884. Serial No. 143,025. (No model.)

To aZZ whom it may concern:

Be it known that I, JAMES A. ll/IARSH, of Cleveland, county of Ouyahoga, State of Ohio, haveinvented certain new and useful Improvements in Vapor-Stoves; and I. do hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make or use the same.

My invention relates to vapor-burners; and it consists of the arrangement and construction of parts, as hereinafter described and particularly claimed.

It is illustrated in the accompanying drawings, in which Figure 1 is a side view in elevation, partly in section; Fig. 2, a vertical section of a main burner; Fig. 8, a cross-section on line a .c' of Fig. 2, showing the deflector in elevationand the burner-cap in dotted lines; Fig. 4t, an end view of the side burner, partly in section, showing the heating-plate and connecting-pipes; Fig. 5, a sectional view in a plane passing through the axis of one of the connecting-pipes H on the line at m, Fig. 4.

In the drawings, qt is the retort or vaporizing-chamber, to which gasoline is supplied through the pipe P in connection with a form of supply-pipe and safety-tank, Q X M f Gr, the latter-mentioned features constituting the subject of my pending application filed on or about May 25, 1885, Serial No. 167,341.

O is a main burner or cone similar to one described in Patent No. 270,253, and is provided with upper, middle, and lower jet-openings, b b I).

B is a valve which controls the flow of fluid or gas from the retort A, in which the gas is generated, and is located in the chamber B, which is connected to the retort by a suitable duct.

Beneath the chamber B is a chamber, D, which is designed as a commingling'chamber, and is providedwith a short induction tube or opening, D, for admitting gas and the outer air thereto, and an orifice, I), from which ignited gas 0 is conducted to jet-orifices in the burner O, as hereinafter described. Leading from the retort A and chamber B" is a duct ,or pipe, a, which connects with a bottom crosspipe, to, and serves to convey gas or fluid to the needle jets or orifices d d. Beneath the jet d is located a needle-valve, 0, provided with a wheel-handle and serving to control the flow of gas or fluid from orifice (1 into the opening 1) in the bottom of the comminglingchamber D.

Extending laterally from the side of the chamber 13 is a pipe, H, which serves to convey gas or fluid from said chamber to a side burner, K. This side burner is also p-rovided with jetopenings b" b If, and a heater-plate, S, is secured to the frame-work S at a point at one side of the burner and beneath the same, so as to deflect the flame from a pipe, F, leading from the commingling-chamber of the main burner, as hereinafter described. A duct or pipe, h, leads from the end of pipe H to the burner-jet h beneath the side burner, K, as shown.

F represents a pipe leading from the side of the under commingling-chamber, D, laterally and extending to apoint near the sideburner, K, as shown. The open end f of the pipe F is in proximity to the pipe h, which connects pipe H and burner K, and to the lower jetorifice, b. One object of the pipe F is to heat the burner K for the purpose of initial starting, and another object is to automatically rekindle or reignite the gas in either burner when the light at that point has been accidentally or otherwise extinguished.

In operating the apparatus, if it is desired simply to create and maintain a constant flame at the open end of pipe F for initial starting, valve 0, which controls jet-orifice cl, should be open to allow afull flow of gas,which will pass through pipe F, (to be lighted by hand at the open end of the same,).projecting a flame, 6, against the plate S of the side burner, K, and under orifices, b". If it is desired to have pipe Fmaintained as an automatic relighting-tube, needle-orifice d should be reduced by a par tial closing of valve 0, so that a very small quantity of gas will be discharged from orifice (1 into the open end of pipe D, the said gas taking with it into pipe F such a proportion of air as will render the compound explosive within the pipe F, in which condition ignition of the gas unlighted at either end will antomatically and necessarily ensueif one burner is out and the other lighted. WVhen this condition of the gas is arrived at, if the gas at the side burner is lighted and burning, as above explained, and the main burner is unlighted, the

flame or explosion will be carried back from the jets b in the side burner through pipe F to chamber D, through orifice Z), against and around deflector R, and to jet-orifices b b I) in the main burner. 11', by any cause under this condition of things, the side burner should become extinguished, the flame or explosion carried from chamber D and pipe I will automatically relight the side burner. If it is desired to maintain a light alone in the main burner, valve C may be operated to cut off all supply of gas to the side burner, and gas is then alone supplied to the main bu rner through orifice d controlled by valve E.

The main burner has a deflector, R, (more fully shown and explained in Patent No. 270,253,) but itis manifest that any burner can be used at end of pipe F, provided it is placed in close proximity, so that issuingjets can be lighted.

Another form of apparatus for accomplish ing the relighting of the burner when extinguished is made the subject of another pending application, No.l97,37l,filed AprilLlSSG.

\Vhat I claim, and desire to secure by Letters Patent, is

1. In a gasoline-stove, a retort, a commingling-ehamber, and a duct connecting said retort and said chamber, in combination with a side burner and a communicating pipe between the said chamber and the side burner, whereby ignited gas may be carried from one to the other, as and for the purpose set forth.

2. In a gasoline-stove provided with burners, the combination, with said burners, of a commingling-pipe having an open end in close proximity to one burner and the other end connected with an outer air-inlet and a gas-jet orifice controlled by a valve for throwing the gas into said pipe, substantially as described.

3. In agasolinestove provided with burners, one of which has a oommingling-chamber, the combinatiomwith said burners, ofa communieating pipe with one end entering the commingling-chamber and the other end open to the outer air in close proximity to the other burner, whereby a gas-flame may be started and maintained at said open end,substantially as described.

4. The combination of a main burner having a retort or generating-chamber, a second ary chamber connected to the retort by a duct, side burners and pipes leading from said secondary chamber to the side burners, a pipe leading from the secondary chamber to the jetorifice of the main burner, and a valve located in said secondary'chamber, whereby the gas or fluid may be cut off from all the burners by the turning of said valve, as set forth.

5. The combination of a burner provided with a retort or generating-chamber, a pipe leading from said retort to a side burner connected therewith, a commingling chamber having an opening beneath it, and a supplemental pipe leading from the comminglingchamber and opening to the said side burners, and in proximity thereto, substantially as and for the purpose described.

6. The combination of a main burner having a commingling-chamber provided with lateral orifices, a comminglingchamber located at the side of said burner and provided with orifices or jets on its inner side, a pipe leading from said latter commingling-chamber to a side burner and having an open end thereat, and a chamber and duct through which the main burner and the side commingling chamber are connected, whereby the main burner may be automatically ignited, as Set forth.

7. The combination of a retort, a commingling-chamber, a duet for conveying gas from the retort to said chamber, a pipeleading from said chamber to and in proximity to a side burner, and a side burner whereby commingled air and gas are conveyed from the commingling-chamber to the exposed surfaces of the side burners, as set forth.

In testimony whereof I affix my signature, in presence of two witnesses.

JAMES A. MARSH.
