SPECIFICATION forming part of Letters Patent No. 705,418, dated July 22, 1902.

Application filed April 14, 1902.

.To all whom, it may concern.- Be it known that I, HERMANN ADOLPH ERNST MENNE, a subject of the German Emperor, residing at Oreuzthal, Westphalia, 5 Germany, have invented new and usefullmprovements in Burners for the Removal of Hardened Massesin Furnaces or the Like, of which the following is a specification.

My present invention relates to a burner orv [O jet for carrying out the method for the removal or fusion of hardened masses in fur naces and the like. It is necessary to prtect the burner-point, as the latter is subject to the action while in the holes formed in the molten material, which holes gradually increase in depth, of the flame thrown back by the molten mass or of the oxygen gas and the molten material. The jet, therefore, which has only a small amount of protective matezo rial, would melt away much quicker than the material treated. The material used for protecting the point of the burner orjet must be a hard, refractory, non-combustible, or only slightly-combustible, material and not in- 2 5 fluenced by changes of temperature. The burnerprotecting means known and used hitherto-as, for instance, steatite, platinum, or the like-do not comply with these requirements.

According to the present invention the fusion of the burner-point is prevented by a casing of refractory and slowly-combustible materia1as, for instance, compressed coal, graphite, coke, gas-retort carbon, magnesite, 3 5 carborundnm, or the 1ikeor by providing a water-cooling device around the nozzle.

Inthe drawings, Figure 1 shows the burner with its point protected. Fig.2 shows the burner-head and the gas-supply connection on an enlarged scale. Fig 3 is a section on .the line as w of Fig. 2 as seen in the direction of the arrows. Fig. 4 is a section on the line y y of Fig. 5, which shows a burner-head with a water-cooling device.

In the outer tube a, which supplies the combustible gashydrogen-petroleum vapors or the likeis arranged the feed-pipe Z) for the Serial No. 102,886. (No model.)

oxygen gas. The oxygen-tube?) isprovided at its rear 'end with a nut c, and the rear end protecting-casing upon the expansion of thetube.

f represents set-screws to position the tube 1), and a b are the connecting parts for the gas-supply pipes.

The casingor protector can also be made of several single rings of carbon or the like, so as to restrict themelting of the burner= point only down to the next ring in case the first ring should, break. As already mentioned, the meltingof the burner-point can be also prevented bythe use of a water-cooling device, as shown in Figs. 4. and 5. The cooling-water enters at 9, passes into the cooling-chamber g, surrounds and cools the tube a, and leaves at 9 As fresh water is continually admitted, it effects a continuous cooling of the burner-point. This part g may be made of any suitable material.

The connectingunions or pipes for the gassupply are preferably provided with valves or taps for the regulation of the gas-supply.

The inner tube can be arranged so as to be withdrawn through a convenient stuffing-box, and its discharge-opening is preferably situated about ten millimeters within the 0pening of 1 the outer tube.

Having now particularly described the nature of my invention and how the same is to be performed, I declare that what I claim is 1. In a burner, the combination of concentric pipes for conveying fuel and oxygen,

yielding material surrounding the outer-pipe at its delivery end, and a covering of hardrefractory non-conducting materiaf'surronnd ing'said yielding material, substantially as described.

2. In a burner, the combination of concenmeans for centering the inner pipe in the outer name to this specification in the presence of pipe, a circular layer of yielding material surtwo subscribing witnesses. rounding the delivery end of the outer pipe and a circular covering of hard refractory 5 non-conducting material surrounding said Witnesses:

yielding material, substantially as described. WALDEMAR HAUPT,

In testimony whereof I have signed my HENRY HASPER.
