JOHN J. SOHILLINGER, OF NEW YORK, N. Y.

APPARATUS FOR HEATING ASPHALTUM, 80C.

SPECIFICATION forming part of Letters Patent No. 322,325, dated July 14,1885.

Application filed J nly 17, 1884.

To aZZ whom it may concern.-

Be it known that I, JOHN J. SCHILLING ER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Apparatus for Heating Asphaltum and other Materials, of which the following is a specification.

This invention relates to apparatus for treating asphaltum or other liquid or semi-liquid material; and it has for its object to improve the construction of the bottom of the vessel which contains the material, and is subjected to the direct action of heat from a furnace in which said vessel is suspended. In this class of apparatus it isimportaut to provide the liquid-containing vessel .-with a bottom which can be subjected to the direct action of the fire in the furnace without dauger of the bottom rapidly burning out, or the formation of hard scales on such bottom. It is also important that the refractory bottom be so supported and connected with the vessel as to provide a perfectly-tight joint, in order to prevent the fire from igniting the asphaltum, which would likely cause an explosion. I accomplish these purposes in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, illustrating my invention, in which- Figure 1 represents a vertical central section of my apparatus. Fig. 2 is a plan or top view. Fig. 3 is an inverted plan of the heating-vesseldetached.

Similar letters indicate corresponding parts.

In the drawings, the letterA designates the heating-vessel, which is composed of a metallic jacket, a, open at both ends, and of a bottom, 1), made of fire-clay or equivalent refractory material. The bottom is supported upon angle-irons c, which are riveted or otherwise firmly secured to the bottom edge of the jacket. In the example represented in the drawings four such angle-irons are shown;

.but the number may be increased, or a continuous inwardly-projecting flange may be formed on the lower edge of the jacket, to form the support of the bottom b. After the bottom has been adjusted upon its supports the space between its circumference and the inner (No model.)

surface of the jacket is filled up with fire-clay, to provide a sealed joint between the periphcry of the bottom and the inner surface of the vessel, thereby preventing leakage of the liquid asphaltum, and the possibility of an explosion occurring by the flame from the fire igniting the asphaltum.

With the refractory bottom I) is combined a secondary bottom, (1, consisting of a disk of sheet metal, whichis placed loosely into the jacket a.

To the jacket, at or near its top edge, are firmly secured a series of angle-irons, e, which support the heating-vessel in the furnace B. This furnace is of a well-known construction, and it will be readily seen, by inspecting Fig. 1, that the fire-grate f is so situated that the bottom of the heating-vessel is exposed to. the direct action of the fire.

In heating certain materials-such, for instance, as asphaltum-a very high heat is required, and for that reason it is desirable that the bottom of the heating-vessel shall be exposed to the direct action of the fire.

Where the bottom of the vessel is of metal exposed to the direct action of the fire, a hard scale forms on such bottom audit soon burns out, whereas by my invention this is avoided while the bottom is exposed to the direct action of the fire on the grate.

I am aware that the sheet-metal bottom of a culinary boiler has been formed of two separated thicknesses, between which is a filling of powdered chalk, magnesia, or plaster-ofparis. I am also aware that in culinary boilers a soapstone slab has been removably held in the bottom opening of the vessel for intercepting the heat from the stove on which the vessel is used. Such, therefore, I do not claim.

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

1. A vessel for heating asphaltum and similar material, consisting of a furnace having a grate in its lower portion, a metallic jacket suspended above the grate, a bottom of a fireclay disk arranged within the jacket, and a luting of fire-clay interposed between the cirpurpose described.
