Specification of Letters Patent.
Patented Sept. 19, 1905.
Application filed April 29, 1903. Serial No. 154,795.
To all whom it may concern:
Be it known that I, PHILIP ALEXANDER MAOKAY, a citizen of the United States, residing at Newcastle, in the county of Northumberland and State of New South Wales, Australia, have invented a certain new and useful Improvement in Refractory Receptacles, (Case No. 2,) of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to receptacles used in connection with chemical or metallurgical processes, more particularly to receptacles of refractory material, such as furnace-linings, crucibles, and retorts. Such receptacles are commonly used to hold materials which are to undergo chemical changes due to the application of heat. In many chemical operations it has been found diflicult to provide such receptacles which would not be injur-iously affected by the chemical reactions going on therein. These injurious eifects frequently manifest themselves by a pitting or scoring of the receptacles, which finally results in the perforation of the walls thereof. While it is possible to provide substances which will not be injuriously affected by the before-mentioned reactions, such substances are otherwise unfit for the purpose of making receptacles. It has heretofore been proposed to line retorts with a substance adapted to prevent the corrosion thereof due to the attack of the chemical agencies within the retort. I have found in practice that such receptacles are much more subject to corrosion in certain localities than in others, and my invention provides for the insertion of a section of noncorrosible material at thelocality or localities at which the attack of the chemical agency is most violent.
I will more particularly describe my invention by reference to the accompanying drawings, in which Figure 1 is a perspective view illustrating one embodiment of my invention. Fig. 2 is an end elevation of the same, and Fig. 3 is a cross-sectional view taken on line 3 3 of Fig. 1.
I have illustrated my invention as applied to a retort such as is commonly used in the distillation of zinc from its ores. I have found that such retorts are subject to violent scor-.
ing and corrosion largely on the lower surface thereof. The scoring or corrosion begins on the lower and inner side of the retort, which is finally rendered useless by a complete perforation.
I have shown a retort having a shell 4. of substantially elliptical cross-section, of which the sides 5 5 are placed substantially vertical when in position within a furnace. The walls of the retort may desirably be made of a suitable refractory material or clay, such as mother-of-retort. These walls are of substantially the same thickness throughout. The lower side of the shell is provided with an extension in the form of a shallow trough 6, adapted to retain in position a suitable insert 7, of carbon or graphite or a mixture of clay and graphite or, indeed, any non-corrosible substance which will amalgamate with clay mother-of-retort and which having substantially the same coefficient of expansion and contraction will preserve a tight joint between the insert and the shell after drying and burning of the retort. I have found that such an insert in the lower side of a retort used in the distillation of Zinc from its ores will largely prevent the corrosion and destruction of the retort due to the attack of chemical or physical reactions.
I have described my invention with particular reference to a retort which may be used for distillation purposes; but it will be apparent to those skilled in the art that it may be applied to furnace-linings and crucibles which are subject to rapid corrosion in certain localities.
While I have described one particular embodiment of my invention, it will be apparent that many modifications therein may be employed without departing from the spirit thereof, and I do not wish to limit myself, therefore, to the precise disclosure herein set forth; but,
Having described my invention, I claim as new and desire to secure by Letters Patent 1. In a retort, the combination with an elliptical tubular shell of refractory material, a narrow strip of said shell at the lower part of the retort being offset outwardly to form a shell-trough within the shell, and a supporting-base for the retort at the outside of the shell, and an insert of non-corrosible material in said trough, said insert having the same coefficient of expansion as the material of the shell and having its upper surface continuous with the interior surface of the shell.
2. A retort consisting of the elliptical tubuthe inner surface of the shell and to be coni0 lar shell 4:, a narrow section at the lower part tin-nous therewith. of said shell being offset outwardly to form In witness whereof I here-unto subscribe my a longitudinal trough within the shell, and a name this 24th day of March, A. D. 1903.
3 supporting-base for the retort, an insert 7 of non-corrosible material having the same 00- PHILIP ALEXANDER MAGKAY' eflicient of expansion as the shell and securely Witnesses: fitting in said trough, the upper surface of J. E. ANDERSON, said insert being rounded to correspond with KARL J ESEM.
