To a/Zwhoml tmay concern:

Be it known 'that the t'ollowingisafull, clear and exact-description of an Improved Gas- Burner invented by RICHARD B. LooKE,'of

New Orleans, and VWlLLIAM B. ULRICH, of Concordia Parish, in the State of Louisiana, reference being had to the accompan yin gdrawings, making whicht 1 t Figure lis -a side elevation of an improved burner complete-.aud ready foruse. Fig. 2 is an enlarged diametrical section 'thro'ughthe' improved burner, showing Athe cock turned so asto eut oft' the supply of gas to the primary burner or tips. Fig. 3 is a diametricalsection with the globular chamber and. primary burner removed, showing the cock turned so as to allow a full Iiow of gas to the primary burner or tips.

-Similar letters indicate' corresponding partsin the several figures.

The object of this invention is to provide for. the retention, during the time that it is Ilot required to use a gas-burner for illumination, ot'a small flame by which the gas when turned on in sutiicient tion may be ignited.

The invention consists, first, in a novel construction ofa eocl; to be applied in connection with the burner for this purpose.

To enable others skilled in the art to understand the invention, the following is given as a description of its construction and operation, under one forinor mode of applying it at least.

In the accompanying drawings, Figs. 1 and 2, the inventionv is represented as applied to the well-known form of gas-burner, which will here be termed the primary burner, consisting of twoburners or tips, A A, inclined toward each other and screwed into curved branches B B, so that the two jets of gas issuing froin the orifices of the tipswill impinge upon each other Vand present a broad and beautiful tlanle. These branches 1B B terminate at their lower ends in a central tube, B,

` which is screwed on theend of the gas-pipe (l,A as shown in Figs. 2 and 3. Atashort dis'- tanee below the tips A A, a'eock, D, is applied to the pipe G and fitted gas-tight, so as to allow ol' the gas being shut oit' from these tips or turned on at pleasure. This cock D a part of this specification, in,

quantity for illulninais constructed with an orifice, a, through it, throughfwhich the gas is allowed to' escape freely to the .tips A A-when this cock is turned, as shown in Fig. 3. When the cock is turned with its orifice a at right angles tothe'pipe C, as in Fig. 2,. the gas will be cut off' from the -tips A A, butwill be allowed to flow in small quan titles through the tine annular grooves b, which are made in thecirc'umference of the cock in a planeintersecting the. axis of the orifice a, as shown in Figs. 2 and-3, from which grooves the gas is conducted through a small pipe, c, to the secondary burner or'tip, g, as will-.be presently described.

' A division-piece, d, is secured i'n the center of the orifice a, soas to .leave narrow spaces e e at its extremities for the purpose of allowing gas to rush suddenly through the small pipe C to the tip g, just before the full flow or head of gas yis turned ion tothe tips A A. rlhose ends of the divisional piece dwhich are betweenthe spaces ce are designed to serve as valves for closing vthe lower. end of the small pipe'c when the orifice ais inline with the bore of the pipe Gv and the full tlow of gas is .admitted to the tips A A. When said pipe.

c is closed, the small blue flame of the tip g will be extinguished. The upper end of the' taper or tip g is passed gas-tight through a hole which is drilled through the crotch of the branch pipes B B, so that the fine orifice of this tip will be in a vertical plane beneath the converging ends of the tips A A and sufficiently near these ends to allow of the communication of flame to the .gas issuing there from bythe flame of the tips A A.

The small pipe cis secured in the center of the larger gas-pipe C in such manner that the gas rising through the orifice of cock D will not be materially obstructed in its passage to the tips A A.

The pipe G may be a short section of pipe of suiiicient length to receive the cock D and internal gas-tu be,c, and havin ga female screwthread or coupling formed in its lower end so that it can be screwed on a gas-pipe in place of any of the old forms o burners.

At the base of the curved branches B B a male screw-tli read is formed on the central tube,B/, upon which is screwed a hollow globe, hood, or shel1,G, which -`incloses the tips A A i v l 3'65 belowy their upper ends, and forms an air-sup- 'ply chamber for inducing currents ot' air to rise through the orices 'i 'i at its base and impin ge upon the flame.

The air which rises into the chamber G becomes heated and supplies more or less oxygen to the ame,whether such be the larger one used for illuminating purposes or thel smaller one that is used for igniting. It also protects the small or igniting tlame from being extinguished by strong currents of air, and .should be made opaque, to conceal the same or prevent its being Visible and having an illuminatin g action or effect, which is desirable it should not have. l The operation ofthe burner when constructed as described is very simple. The cock being turned so as to admit gas to the tips A A, this gas is lighted and burns in the usual manner. In the act of shutting ott' the gas't'rom these tips by turning the cock D, and immediately before the full supply ot' gas is cut-off, one of the spaces e is brought beneath the orifice through the tube c, which instantly causes the gas to jet from the tip g and take tire from the nearly-extinguished iiame of the. tips A A.

Thus the tip g will be lighted in the act of cutting ott' the gas from and extinguishing the tips A A. When the space e passes the orifice of the tube c, the gas will be conducted to this tube through the tine groove b in the coclcplug, as before described, and burned with a small blue dame. In the act of turning' on the gasto obtain light, one or the other ofthe spaces at the ends ot' the division d and orifice a of the .cock-plug will be again brought opposite the lower end of the small pipe c, leading to the lighted tip, thus allowing a full pressure of gas to this tip,which will cause its ame to jet upward a suflicient .length to ignite the gas issuing slowly from the oriice of the tips A A. When the cock D is turned fully, the divisional piece d will cut oit' the escape of gas through the tube 'c and extinguish the taper or tip g. Thus the tip y will be extinguished in the act of admitting gas to and lighting the tips A A. lt will thus be seen that the small taper is pro vided for the purpose of lighting the primary burner, or what may be termed the illuminating gas jet or stream issuing therefrom, and not for giving light. Itis preferred to inake this taper so that it shall consume but a trifling amount of gas when in use, and none atv all when the tips A A are lighted.

The invention is here described as applied to converging burner tubes or tips as one practical mode otl carrying it into eect, but it is not confined toV this particular kind of gas-burner, and may be applied to other forms ot' tips by making slight changes in the construction of the parts herein shown, without, however, changing the principle ofthe invention as herein set forth.

Itis obvious that the tine groove b which has here been described as being made in the cock-plug l) may be made in the pipe C, and answer the purpose designed just as well.

What is here claimed, and desired to be secured'by Letters Patent, is-

'1. The divisional piece d, or it-s equivalent, applied to the orifice a of the grooved cock D, and constructed with gas-escapes e c, in combination with a self-lighting burner, substantially as described.

2. The hood or shell G for supplying oxy. gento the burner und for the concealment and protection of the small dame, substantially as described.
