IMPROVEMENT IN GAS-BURNERS FOR THE IVIANUFACTUHE 0F LAMP-BLACK.

Specification forming part of' Letters Patent No. l'lbq'b, dated March 16, 1875; applientien h d January 25, 1875.

To all 'whom t may concern Be it known that I, PETER NEFF, of Gambier, in the county of Knox and State ot Ohio, have invented certain new and useful Improvements in Burners to be Employed in Manufacturing Lamp-Black; and I do hereby declare the following to be a full, clear, and exact dcscription of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this speeilication.

This present application (Gase C) is a modieation or slightly different construction ot' the burner, and forms one of a number of applica cations made by lne for certain improvements in gas-burners to be used in the manufacture of lamp-black.

My invention relates t0 a burner to be applied or employed in the manufacture of lampblaek and consists in forming the said burner with a wide open mouth of greater diameter than that of the pipe or stem ot' the burner, and of a disk or plate located in the said mouth for the purpose of sprezuling` the gas as it emerges from the burner, for the purposes hereinafter set forth.

In the drawing, Figure l is a plan view of the top of my burner. Fig. 2 is a sectional view ofthe same. Fig. 3 is a view oi' a variation of my said invention. Fig. fl is another Variation.

In the manufacture of lamp-black from gas it is desirable that the gas should issue from the burner in sueh a manner as to cause it to be burned at a low temperature, and at the same time so as to waste or permit to go uneonsulned as little gas as possible. My invention is designed to effect this improvement.

A is a service-pipe, or a pipe through which the gas is fed to the burner. B is the burner, into which the ow ot gas is regulated by the stop-eock G. I) is the enlarged or widened mouth of the burner. E is a disk or plate, that is suspended in any suitable manner so as to be preferably just above the mouth of the burner, and to be about the same size as the said mouth. It is also made preferably in a dish shape, so as to direct the gas in its mojtion out under the said disk.

The operation is as fellows: Gas, entering the said burner through the teedpipe, enters the enlarged portion, strikes against the under side ofthe disk E, and is directed outward in all directions in a large tlattened shape, as 1n the drawing. In this way the gas is spread into a hollow conical form, and will have but a thin wall of the said gas exposed upon its outside to the oxygen ot the air, the inside being hollow, or not filled with gas, as would be the ease were the disk dispensed with.

I3 y forming the burner iu this manner, with a wide open mouth and the disk` B, the gas 1s made to burn with a very slight pressure and at a low temperature. All or nearly all ot' the gas is consumed on the surface, little, if any, being permitted to rise to the apex ot' the cone, where the heat is usually of sueh intensity as to burn up the carbon.

Instead 0i' employing the disk E in the mauner shown in Figs. l and 2, the disk may be secured in a position in any suitable manner, as, for instance, in the manner shown in Fig. or it way be suspended in the center by a rod or brace, substantially as shown in Fig. 4, or in any other suitable manner whereby the disk is held in the enlarged mouth ot' the burner. So, also, the disk may not, necessarily, be dished, as shown in Fig. l, but may be iiat, or any other suitable form, and may extend out to a greater or less extent.

In constructing the burner it maybe formed as shown in Fig. 2, wherein the enlarged mouth is reduced by successive reducing-,joints until of a size sufficient to attach it to the feed-pipe A, or the said burner may be east 0r otherwise i'ormed-in the first instance ot' a tapering shape, small at the bottom and large at the top, as shown in Fig. 3; or the burner may be in the i'crm ot' un elbow, as shown in Fig. 4, without departing from the nature of my invention, which contemplates a burner which has a broad widened mouth and a diminished stein, and a dellecting plate or disk in an open mouth for the purpose of burning gas at a low temperature for the manufacture of lampblaek.

This burner is designed for use in any mechanism, or in any place where gas, either natural or artilicial, is burned in the manufacture of lam p-blaek, the essential feature being that the gas is fcd to the burner through a pipe or orice less than the burner, and is permitted to flow freely through and out from the burner.

It is obvious from the foregoing that the gas may be burned from the end of a pipe of uniform dimensions, and the flow of gas be governed by the stop-cock, so that the gas iiowing through the diminished orifice formed by the stop-cock Will oW freely to the end of the pipe, Where it is burned.

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the wide open mouth O of the burner for use in the manufacture of lamp-black, of lthe removable deecting-disk D, substantially as and for the purposes described.

PETER NEFF.
