|MPROVEMENT |N- GAS-BURNERS.
Specification forming part of Letters Patent No. 140,164, dated June 24,1873; application tiled October 8, 1872.
To all whom it may concern:
Be it known that we, JOHN RICHARDSON and THOMAS D. RICHARDSON, of New York, in the county Ot' New York andState of New York, have invented certain Improvements in Gras-Burners, of which the following is a specitication: v
Our invention relates to that class of burners used for mixing and burning two different gases-such, for instance, as oxygen and hydrogen--and it consists in a novel manner of constructing them, as hereinafter explained.
Figure l is a perspective view of one of our burners; Figs. 2, 3, and 4, vertical central sections of different forms or modifications of the same; Fig.'5, a top view of the burner represented inA Fig. 4 5 and Fig. 6 a cross-section on the lines w In constructing our burners we provide a tubular body or shell, A, having aclosed top, and mount concentrically therein a tube, B, as shown, the tube being made of such size that an annular space is left between it and the body. One of the gases is admitted into the tube B and the other into the annular space. The upper part of the body we divide into chambers or divisions c and b, which communicate, respectively, with the annular space and the central tube, as shown, so that the two gases are separated and prevented from mingling while in the burner. The number and form of the divisions or chambers,
j and of the orifices from which the gases issue,
may be varied according to the size and shape of flame which may be required. When an ordinary flat llame is desired, we prefer to construct the burner as in Fig. 2, with a single central division, and with two parallel slits, c, opening one into each of the two chambers. The two slits We give a slight inclination toward each other, as shown. The gas fed into the annular space rises and issues in a thin flat jet from one of the slits, while the gas fed into the central tube issues in a similar jet from the other slit. The two jetsimpinging against each other cause a thorough and uniform mixture of the two gases and produce a large at flamefwhen lighted. If preferred, the burner may be constructed as in Fig. 3, with 'threeslits instead of two, the central one opening from the central tube, and the others from the annular space. Inv this case the jet from the central tube issues between the other two. y The two outside slits are slightly inclined toward each other, so that their jets will impinge against the sides of the central jet. By this arrangement ofthe three jets the gases are mingled with even greater certainty and uniformity than by the burner having two slits, as before described. Another advantage of this arrangement is that it produces a very steady flame, as the two outside jets counteract each other, and cause the iame to ascend vertically. When the burner with two slits is used there is a liability of the flame leaning to one side in case the pressure of one of the gases becomes greater than that of the other; but when the three slits are used there is no such difficulty. When it is desired to produce a burner with a tubular or Argand ame we adopt the construction shown in Figs. 4 and 5. The central tubeB has its upper end flared outward and united to the body or shell. Through the upper end a circular row offine holes, fi, open into the annular space, as shown. In the top of the central,V tube a disk, H, is secured, as shown, for the purposes of causing the gas to issue in a tubular jet, and of deflecting it outward to meet that issuing from the holes t'. l
The disk may be made smooth, or it may be grooved, as shown, so as to direct the greater portion of the gas directly toward the holes. In order to ad mit of the disk being adjusted vertically, it is mounted on a central screwstem, as shown, but it may, of course, be secured rigidly in place. Instead of the holes i, a circular slit maybe made in the top of the burner.
It will be seen that the construction and` operation of this burner are the Same as that of the others, except that the openings or orifices for the escape of the gases are circular instead of straight.
The burners constructed on our plan are extremely simple, cheap, and durable, and produce a very perfect mixture of the gases. The gases unite and burn above the top of the burner, and consequently the burner is not subjected to a dangerous or injurious heat, which is the great sourceof trouble in this class of burners as ordinarily constructed. The central tube being secured at its upper end only, leaves a clear free passage for the gas around it. As the one supply-pipe is inside of the other, and concealed from sight, the burner may be applied to pipes arranged in a like manner, so that but the one pipe will be in view. The burner will, of course, present the appearance of an ordinary burner using one kind of gas. This arrangement of the double concentric pipes forrns, however, a separate invention, for which I intend to make a separate application.
Having thus described our invention, what we claim is- 1. A compound gas-burner, consisting of an inner and an outer tube arranged to convey the gases separately to the point of combustion, and having their opposite ends arranged concentrically, so that said burner can be screwed on the compound pipe in the same manner that ordinary burners are attached to single pipes, substantially as herein shown and described.
2. A compound gas-burner consisting merely of two concentric tubes, secured together and arranged at their upper ends, as shown and described, but left uncovered at their lower ends in order that they may be attached to concentric supplypipes, as shown and set forth.
3. The compound flat-flame burner, consisting of the concentric tubes having their upper ends connected, and provided with the partitions a and slits or openings c, as shown and described.
