UNITED STATES PATENT OFFICE.

W. W. BATCHELDER, OF NEW YORK, N. Y.

GAS-BURNER.

Specification of Letters Patent No. 18,230, dated September 22, 1857.

To an whom it may concern Be it known that I, WILLIAM W. BATCH- ELDER, of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Gas- Burning Apparatus; and I do hereby declare that the following is a full, clear, and

. exact description of the same, reference being made to the annexed drawings, making a part of this specification, which are fully described herein.

Similar letters throughout.

My improvement in gas burners or jets is a superior method of buring illuminating gas, whereby greater economy is obtained in the consumption, as well as a superior quality of light.

The principle consists in causing the gas to issue in succession from two apertures; of different areas, placed near together, and so shaped that the gas shall be made to pass in a thin stratum from the first or lesser aperture to the next or greater aperture, in such manner that the stream shall not be deviated in passing from one to and through the other.

The construction and operation is as follows:

At is the first gas jet, being of common construction, and screwed upon the gas pipe, as usual. This terminates in a fine slit (a) at the top, and would alone form a complete burner such as is technically called a bats wing, and constitutes the first of the two apertures according to my improvement. Over this I place a cap or cover (6) the interior of which is so large as to leave a clear space all around. This has a rounded top across, wherein is also cut a narrow slit (1)), but forming an opening several times the area of the inner slit (a). Near the base of this the cap is pierced with several small holes (0), and finally it is secured in place upon (a) by an adjusting screw or screws The successful Working will depend upon the accuracy of the adjustment of the two aperture (a) and (6). And this requires, first, that the flat stream of gas issuing from (a) shall so indicate similar parts enter (5) that it shall pass through without being deviated or the current broken, which it would be were these two slits not precisely in the same plane.

The second feature of adjustment is that the lateral lines or base of the stratum shall not strike below the ends of the slit (1)) but shall project so as to pass through just above or at the point-s of termination, as in the lines of Figure II, which is a view of the flame shown flatwise, all which adjustment may be readily found by trial, when the gas is burning, and when found, set in position by the screws (d). The flame produced by my improvement is different from that of a common burner in that it is much larger. The light is denser, not so glaring, but much softer, it is more agreeable to the eye, and with an equal consumption of gas-the illumination is much greater This light may still be improved by the admission of air into the cap (5); this is effected through the holes (0) and the air ascends in the direction of the arrows to the top of the said cap where it infringes upon the surface of the gas as it passes from one aperture to the other, issuing wit-h it at (b).

I have described the aperture as a slit, but it may be otherwise formed, provided it be such as to cause a flat stratum of gas to issue in a manner well known. Instead of the holes (0) space might be left to allow the air to pass in at the bottom or through grooves cut up the sides for that purpose.

I claim- The improved method of burning gas, described, viz. combining two apertures of different areas so arranged that a flat stratum of gas issuing in the first instance from the lesser aperture shall infringe and press upon the second and larger aperture placed in the same plane with the issuing jet, and in such manner as to pass it without causing any deviation thereof as described.
