GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 389,757, dated September 18, 1858. Application filed April 2, i987. Serial No. 233,443. (No modeLl Patented in England May 31, 1887. No. 7,885.

.To all whom it may concern:

Be it known that I, EUGNE MOREAU, a citizen of the Republic of France, residingat Philadelphia, in the county of Philadelphia 5 and State of Pennsylvania, have invented certain new and useful Improvements in Gas- Burners, (for which a patent in Great Britain, N o. 7,885, bearing date May 31, 1887, has been obtained,) and I do hereby declare the following-'to be a full, clear, and exact description of the i.nvention,such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of lamps wherein the heat of the products of combustion from the ame is imparted to the air-supply and to the combustible gas for increasing the illuminating-power of the flame; and the nature thereof consists in certain improvements in the construction of burners of such lamps,w hereby a better combustion of the gas is obtained, the number of parts of which the burner is composed lessened, and the cleaning of the gas-passages facilitated.

In the lamp described in English Patent No. 14,335, of November, 1886, the burner which is screwed into the lower part of the gaschamber consists of a tubeplate provided with a large number of holes for holding together the gas tubes, a series of tubes, each of which is passed through the holes in the tube-plate, a ring to which the lower ends of the tubes are secured, and a stem supporting a dellectingbutton whichis screwed into the tube-plate.

My present invention is an improvement on the burner described in the said English patent; and its object is to simplify and render more economical theconstruction ofthe burner, so that it may be finished after Ybeing cast entirely by drilling, turning, and milling machinery adapted to the purpose. According to my present invention, all these parts are constructed of one and the same piece of metal by first turning a casting to the required form,then drilling th rough the same holes for the passage of gas, and nally cutting or milling air-spaces between the holes or bores. I also combine with the burner a central receptacle or chamber, for the reception of impurities, having a 5o removable bottom.

In the accompanying drawings, in which l corresponding parts are designated by similar letters, Figure 1 represents the burner applied to a regenerative gas-lamp of known construction. Fig. 2 is a vertical section showing the 55 burner detached from the lamp. Fig. 3 is a sectional plan of the burner illustrated in Fig. 2. Fig. 4 is a vertical section illustrating the improvements for preventing the deposit of carbon and facilitating the cleaning of the gas- 6o passages. Fig. 5 is a sectional plan of the burner illustrated in Fig. 4. Fig. 6 illustrates a burner the lower rim of which is provided Witha protecting device. Fig. 7 illustrates that part of the burner shown in Fig. 2 which is made in a single piece as it appears before the gas and air passages are drilled or cut therein. Fig. 8 illustrates that part of the burner shown in Fig. 4 which is made in a single piece as it appears before the gas and air passages are drilled or cut therein.

In constructing the burner shown in Figs.` 2 and 3, the casting is first turned in such a manner as to assume the form shown by the outer bounding-lines of Fig. 3, when the delecting-button is removed, the threads upon the periphery and upon the lower part of the rod E being cut in this operation, The requisite holes C-inthis instance twenty eight in number-are then drilled, and the requisite number of slots d-in this instance twentyeight-are afterward milled between the holes or bores C from the annular rimD to the shoulder B, and also above the shoulder B to the top of the cylinder. The buttonFis then fastened upon the stem, and the burner is coinpleted in two parts instead of the many which have been heretofore required. In the burner illustrated in Figs. 4 and 5, the tube-cylinder, instead of extending above the plate or shoulder B, is provided with an inner annular beveled edge, C2, immediately under which is the recess or cup G, constructed in the form of an inverted cone, and provided with a downwardly-projecting tubular stem, E, the bore Vof which is closed by the button F. As the tubes C are cleaned by means of a wire driven through them,which forces the carbon deposits upward, the beveled surface C prevents the accumulation of the carbon residue, and causes it to fall into the recess G below, from which it may be readily removed by unscrewing or ICO removing the button F from the hollow stem E. The lower annular terminal of the burner D is provided with small grooves H, (best shown in Fig. 5,) which compel the air flowing toward the llame to reach the gas at a point very near its exit from the burner, and thereby greatly facilitate its combustion.

In Fig. 6 a shield, J, is shown forprotecting the lowerauular terminal of the burner. This shield is of annular form,and is provided on its outer and inner edges with ring-shaped flanges, which iit about the terminal annulus of the burner and protect it from the oxidizing ef feet of the hot gases. As the shield is removable, it may be readily replaced when it is worn out. which is made of a singlepieee of metalisillustrated as it appears before the gas-passages C are bored and the air-passagesd milled therein.

Having thus described my invention,I claim and desire to secure by Letters Patentl. A gasburuer comprising an annular bottom, drilled holes for the passage of gas, spaces between the gas-passages cnt or milled In Fig. 7 that part of the burnerA out for the passage of air, and a projecting ceptacle or chamber for the reception of impurities, a removable bottom to the central chamber or receptacle, and aseries of gas-pas sages surrounding the central chamber or receptacle, as and for the purpose described.

3. In agas-buruer, the combination of acentral chamber or receptacle communicating with the gaspassages, having its upper end beveled at the entrance of the gas-passages, a tubular extension to the central chamber, a button fastened to said extension, and a series of gas-passages surrounding the tubular extension, as and for the purpose described.

'In testimony whereof I have aliixed my signature in presence of two witnesses.

EUGENE MOREAU.
