IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 170,407, dated November 23, 1875; application filed I October 19, 1875.

To all whom it may concern Be it known that I, ALBERT MARGIUS SIL- BER, of London, England, have invented certain Improvements in Gas-Burners, of which the following is a specification:

This invention relates to an improvement ii constructing burners for the combustion of gas, (similar to those for burning oil or other combustible liquid, for which I obtained Letters of the United States No. 136,104, dated 18th February, 1873,) so that the desired-combustion is effected in a regulated manner, and a steady, uniform, and powerful flame is obtained, of greater brilliancy and intensity than has hitherto been produced with a like consumption of gas by means of any known burners, thus making the gas far more available for illuminating purposes and heatingpurposes than when ordinary burners are used.

I am aware that various plans have been heretofore proposed for supplying atmospheric air to the flame produced by the combustion of hydrocarbon gas but in none of them, as far as my knowledge goes, have proper means been employed for regulating the supply of air so that it is fed to the flame in the proper quantity and at the proper place or places. I have discovered that unless the supply of air is fed so as to be regulated and adjusted to suit the particular burner and body of flame proposed to be maintained the best light which a given supply of gas is capable of affording is. not obtained, whereas when those points are provided for by using burners constructed in the manner hereinafter explained the best light is obtained which the combustion of a given quantity of hydrocarbon gas is capable of producing when burned in atmospheric air.

In carrying out my invention for cylindrical or annular burners, similar to what are known as Argand burners, I employ in the interior of the burner air-feeding passages or air-tubes concentric with the annular gas passage through which the gas flows to the point of ignition, and I also employ one or more airfeeding passages on the outside of the annu- Oare must be taken that the supply of atmospheric airfed through the internal passages is about equal to the supply fed through the external passages. Hence,

the gas passes in its own annular conduit through and between other conduits containing moving columns, cushions, or currents of air supplied to the flame both internally and externally thereof, so that a sufficient quantity of oxygen from the atmospheric air is introduced to obtain a regular, intense, and steady flame. the central internal current of air shall be fed to the flame at a higher point than the annular current that surrounds it.

For the purpose of producing a proper condition of combustion, I sometimes lit, in some cases, over the upper end of the burner provided with the above internal and external air'passages a cap, dome, or cone, which has a slit or other opening at top for the passage of the gas under ignition or combustion. The air thus reaches the flame before or while it emerges into the atmosphere, and what may be described as a heating-chamber is obtained below the point of combustionthat is to say, around or on the sides of the root of the flame.

The accompanying drawings show my improved burner.

Similar letters mark similar parts in all the figures.

The feathered arrows indicate the direction of the air. The plain arrows mark the direction of the flow of the gas to be burned.

Figure l is an elevation; Fig. 2, vertical section; and Fig. 3 is a plan of my burner.

A is the body of the burner--that is to say, the annular or tubular passage through which the gas flows to be ignited or consumed at the upper end.

Gas is supplied to this passage through the pipe a. The top of the body of the burner A is pierced with holes for the emission and ignition of the gas, such holes being formed and arranged in a circular row or disposition, as is usual with what are called Argand or annular burners. O is an air-tube or air-passage within and concentric with the body of the burner A. This passage is fed with atmospheric air through an opening, at, at the lower part or case or shell of the burner, and it supplies such air to the gas-flame internally thereof. Between the air-tube O and the body A a space, 61 is left, which forms an annular or cylindrical air-passage outside and concentric with the air-tube O. F-is a tube It is sometimes convenient that 1 outsideof the body of the burner A, and con centric therewith. It forms What may be described as an upper outer shell or'casing for the burner. The tube F is of larger diameter than the body of the burner A, so that there is an annular space, f, between the tube F and the burner body A, .which space f forms an air-passage concentric with and external of the burner, so that air passes through. it to the outer surface of the flame.

Air is supplied to this passage f through a space at the bottom of the tube F. Thus the gas and the flame emerging from the burner are between two columns, currents, or moving cushions of atmospheric air. His an annular cap of convex, conical, or dome'shape form, fitted on the tube F so as to come to a level higher than that of the level of the burner body A. There is a central opening at the top of this cap H for the passage of the air and of the gas-flame. by a rim seat or gallery M, carrying brackets N, from which rise springy arms a, which retain the chimney in place. The chimney L is shown at Fig. 9. q are abutments or buttresses on the outside of the tube F, opposite the springy arms a, which precludes the chimney from coming into contact with the tube F. Atmospheric air passes inside the chimney, through the annular space left between the seat M and the tube F. s are struts or stays which connect the tube 0 with the burner A.

The other figures are burners of like arran gement with modifications of form.

In all these figures, as before stated, similar letters mark similar parts.

Fig. 1 is an elevation, Fig. 2", a vertical section, and Fig. 3 a plan, of the burner.

Here a tube, B, concentric with the tube 0, is used for the air-passage d". b 0 are air-supply openings, being slots at the bottom of the tubes B G.

In Fig. 4, elevation, Fig. 5, transverse vertical section, and Fig. 6, horizontal section on line as y of Fig. 4, E is a support for the chimney, having orifices e at bottom. for the passage of atmospheric air to the space f. In Fig. 7, elevation, and Fig. 8, vertical section, the air-tube O is bell-mouthed at top, and rises higher than the burner body A. In Fig. 9, elevation, the chimney L is broken away at parts; and Fig. 10, plan, a support, M, for the chimney is shown pierced with orifices m, disposed circularly for the passage of atmospheric air to cool the chimney. t are metal blocks,

or projections, fixed to the support M. The chimney stands on these blocks, so that it does not come into actual contact with the perforated surface of the support M.

The chimney is held The internal air-feeding passages used with l my burners may, in some cases be disposed otherwise than in a circular form.

. The invention may be apphed to oval or other curvilinear-shaped,burners,to rectangular, or triangular, or polygonal burners; but I do not recommend the use of burners other than of the circular form.

It may be observed that, although the proportions of the parts forming the burner will necessarily be modified in accordance with any variation in size of burner .that it may be requisite to make to serve anyspecial object, and, although, as will be evident to practical persons, the proportions of the parts need not be altered in a fixed ratio,1so that they cannot be given according to anyfixed scale, yet it will, in all cases, be possible to. produce the best light from a given supplyof;

gas, it care be taken that the parts be so pro portioned that a proper supply of atmospheric air be provided at the proper part of the flame, as hereinbefore explained.

My improved burners are considerablylonger in the body than burners in ordinary fuse for: burning gas.

In order to produce a powerful light or intense heat I sometimes combineytwo, three,

or moreconcentric annular gas-passages in the same burner, in a manner somewhat; similar to that in which concentric tubesor wick-holders are combined and disposed in, lamps of light-houses, the gas-passagesbeing, of course,

combined with air-feeding passages injmannerf '1. The gas-burner, in which air-ifeeding 1 passages G d f are combined, substantially in the manner and for the purposes described and. shown, respectively, in the figuyes, inclusively. j

If this be done, an effective combustion of the gas will result, 3 such as I secure by my improved burners. a

In this case I find it advantageous
