UNiTeio STaTias FATTTNT ABIEL PEVEY, OF LOVELL, MASSACHUSETTS.
IMPROVEMENT iN REMLTlNG iRN SCRPS.
Specitication forming part of Letters Patent No. qllilel, dated January 15, 1856.
To all whom, it' may concern.-
Be it known that I, ARIEL Pnvnv, of Lowell, in the county of Middlesex and Common wealth of Massachusetts, have invented a novel and useful Method for Remelting Cast-Iron Dust; and I hereby declare that the following specification, in connection with the accompanying drawings and references thereon, constitute a lucid, clear, and exact description of the mode of procedure by which my invention can be carried out.
In referring to said drawings, Figure l denotes a plan or top view of one of my castiron retainingyessels inclosed on all sides, in which the iron-dust is both placed and held while being remelted. Fig. 2 denotes a side elevation of the same. Fig. 3 is a transverse and vertical section of the same on line A B, Fig. l, showing the dust as it is coni-ined in the vessel for remelting.
The nature of my invention consists in the formation of a cast-iron retaining-vessel with one or more holes through its central portion, so as to bring but small thickness ofthe irondust to the fire, this vessel being so constructed as to be inclosed on all sides after the dust has been placed therein, as will be hereinafter seen` In remelting iron-dust practically and economically, a powerful blast of air is necessary, which renders it equally necessary to contine the dust in a retaining-vessel inclosed on all sides, to prevent its being waited away by the blast, which vessel will melt with or a little after the cast-iron dust contained in it, and consequently ei'fectually melt all the dust in the most economical manner, which is the ob ject of my invention.
To enable persons skilled in the art to which iny invention appertains to construct and carry out the saine, I will describe it as follows:
I form a suitable pattern, shaped as seen at Ain the drawings, or any other desired shape, having one or more holes, as seen at C, for the circulation of heat. To the top I iit a cover (seen at B) having several recesses formed in its edge, as seen at E E E E, and tit or cast several projections C seen at D D D D) on the inside ofthe case or vessel A, the cover B being designed to slide down past the projections D D D D by their passing through the notches E E, &c., until the surface ofthe cover B is below the projections D D, &c. Then this cover can be turned around suii'icient for it to catch and be held by them by placing a lever between the projections F F, which are formed or cast on the cover B. Any other desired shape or torni can be adopted for a retainingvessel; but I consider the above a convenient and effectual method of making them, as well as an economical plan. These vessels are filled with cast-iron dust, as seen at G G. lIhen the cover B is placed and secured to the vessel A in the manner just mentioned, when the vessel and contents are ready to be charged into the furnace the same as any other iron. The melting commences usually at the lower or bottom part ot' the vessel, which is gradually melted through, and ot' course causing the dust to iirst become pasty and then to melt with or just before the vessel itself, which et'- fectually retains all the cast-iron dust until melted, which produces as great per cent. of castings as any iron, as I have ascertained by many experiments and the practical working of my invention.
It is necessary to make use of a blast of air to remelt cast-iron dust so powerful that nearly all the dust would be wat'ted away it' it were not streuuously retained until so melted, which my invention actually and practically accomplishes.
That I claim as my invent-ion is My within-described retaining-vessel or its equivalent, which is to be iilled, when cold, with cast-iron dust or chips, also cold or withoutnrst being heated, roasted, or pressed; then the vessel is to be inclosed tight on all sides, when it and its contents are ready to be charged into the furnace for melting, substantially in the manner and for the purposes fully set forth.
