GAS-BURNER FOR sTovss.

SPECIFICATION forming part of Iletters Patent No. 527,566, dated October 1'6, 1894.

Application led December 14, 1893. Serial No. 493,668. (No model.)

To all whom it may concern:

Be it known that I, JACOB B. WALLACE, a citizen of the United States, residing ,at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Gas-B urners for 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 saine.

This invention relates to gas burners'for stoves, and consists in certain improvements in the construction thereof as will be hereinf after fully described and pointed out in the claims.

The invention is illustrated in the accompanying drawings as follows:

Figure l shows a plan of a burner and its connections made in accordance with my invention, the top of the stove being removed and the mixer and contiguous parts in section. Fig. 2 isla section of said burner on the lines 2 2--2-2.

A marks the main burner; A', a simmering burner placed within th main burner; B, the feed pipe of the'main burner; B, the feed pipe of the simmering burner; C, the mixer; c, the jet orifice; D, the controlling cock; E,

'the gas supply pipe; F,the stove top; and F the side of the stove.

The bodies of the burners, a, may be made of any desired contour. A burner cap, a', with its sides preferably at an angle, as shown, is placed Yon the burnerbody and has the burner jets, a2, passing through the cap perpendicularly to it, thereby giving them an upward and outward tendency.

Extending upwardly from the burner cap, a', are studs, as, about an eighth of an inch in height, and on these studs rest the roof caps, A2 the roof cap of the main burner being ring shaped, allowing the jets to pass both inwardly and outwardly around it from the inwardly and outwardly directed jet oriiices of the main burner.

Screws, a4, are passed through the roof cap, studs and burner cap, and are screwed into the bottom of the burner body, thus holding the parts tightly together. The roof cap is of sufficient width to project over the burner jets. This keeps the jets clear of the usual accumulations on the burners caused among other things bythe frequent overflow of vessels heated by them,and insures a clean and even flow from each` jet. In, order that the roof cap may be effective for, this purpose it is necessary that the under side should be substantially flat or inclined from the edges,

vas otherwise (where there is a declination from the edges) the adhesive quality of the liquids which this roof cap is intended to shed will carry said liquids along the under surface of said cap and over and onto the burner.

The direction of the jets is such that the iiame strikes the lower edges of the roof caps,

'and this gives it the proper lateral deflection.

By placing the ring shapedroof cap over the main burner on studs, c3, an air space is made between the burner and the roof cap. This gives a free circulation of air on all sides of the jets, and insures a sufficient air exposure to obtain perfect combustion, and it also forms a communicating passage between the outer and inner jets so that either will lighty ythe stove preferably at the side opposite that from which the feed pipes lead, and as far from the burner as is possible in the limited space of the stove, so the are of movement of the mixer ends of the feed pipes may be as near a' straight line as possible. Inthe construction shown in the drawings an arm, G, is attached to the burners, and is hinged or pivoted to the stove top at, g. The feed pipe of the simmering burner passes under the main burner, and the mixer ends of the pipes rest on the shoulder, f, on the stove side, and a handle, H, extends from them through the slot, f', in the stove side. By pushing the handle from right to left or vice versa either feed pipe may be swung before the single jet orifice, c. By this construction it is possible to supply any one of two or more burners IOO from one mixer and jet orifice, and the change can be accomplished by means of the handle from without the stove frame.

l. In a gas stove, the combination with the burner thereof; of a roof-cap placed above said burner and having such width and surface contour as to shed from the jet orifices of said burner liquids or matter falling from above said burner.

2. In a gas stove, the combination with the burner thereof; of a ring shaped roof cap set above said burner, leaving an air space between it and said burner, and which projects from the top of said burner out over the burner jets, for the purposes set forth.

3. In a gas stove, the combination with the burner thereof; of. a ring shaped roof cap set above said burner, leaving an air space between it and said burner, and having such width and surface contour as to shed from the jet orifices of said burner liquids or matter falling from above said burner.

4. In a gas stove, the combination of a ring shaped burner therefor having series of j etsV 5. In a gas stove, the combination of a ring shaped burner therefor having inwardly and outwardly directed series of jets; and a ring shaped roof cap set above said burner leaving a communicating passage between it and said burner and between the inner and outer series of jets, said roof cap having such width and contour as to shed from the jet orifices of said burner liquids or matter falling from above said burner.

6. In a gas stove, the combination of a multiple burner having a pivotal movement and each burner of which having a separate feed pipe so arranged that any one of them can be swung in line with a single gas supply by the pivotal movement of said burner; and the gas supply connections.

7. In a gas stove, the combination of a multiple burner that is pivoted to the stove at one side of the burner and each of its burners having a separate feed pipe arranged at the opposite side from the pivot and so placed that any one of them can be swung in line with a single common gas supply by swinging the burner; and the gas connections.

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

JACOB B. WALLACE.
