The Schedule referred to ln than Letter Patent and making par-t f the sama To all whom it may concern' Bc it known that we, Joux HAmLroN, L. E. H ..\..v s: :siliconen W. HAMILTON, and JOSEPH Hann.-

Tox, of'W'hceling, in the. county of O-hio and State of West Virginia, have invented certain new and usefnl Improvements in Ore-Crushers and we do hercby declare that the Vfollowing isa full, clear, and exact description thereof, reference being had to the accompanying drawings and tothe letters of reference marked thereon, in whichliigure 1 is a perspective view;

Figure Q is a side view; and

Figure 3 is a plan view of the bottomv or hopper.

Figure 4 is a plan view;

#Figure 5 is a cross-section through the bottom, at :v x, of lig. 2; and Figure 6 is a side view ofonc of the braces attached to the bracejand axle; r

'.lo enable others skilled in the ait to make and use our, invention, we u ill describe its construction and operation, so that any one skilled in theartcan construct and operate the same.

ln thc construction of our invention, in fig. 1-

A is the bottom, made of solid plank.

B B B B, four standards, rising up higher than the hopper orcrushing-wheels Diagonally to these uprights are cross-bars C C, crossing each other in the center at right angles'rand which constitute the frame-work 'ot' the machine.v

D 'is an upright shaft, resting'on the bottom, having a journal, E, attached to the bottom by means -of screws, and which journal is detachable, so that' when the spindle is worn o'ut or broken, it can be easily re-. moved, and another one substituted. g

- Fitting to this journal E is a journal-box, F, let into the lower end of the shaft, so that it can, when worn,

.be removed, and another journal-box inserted.

A straight shaft, G, passes. at right angles to the upright shaft, and through it and which is the axle, on which the wheels revolve.

On this cross-shaft or axle are placed between the wheels and upright shaft, two sleeves, H H, which `serve to keepthe wheels in proper position in revolving, and to prevent them from running in toward the -`center. 4

Dircctlyiabove this axle is an arm, T, upon the up. right shaft, atright angles to the axle, and is to support the braces K K, which extend 'out beyond thc wheels, and to which are attached rods L L, which are attached to the axle at each outer end, and are to hold the wheels on the axle.

The'object of this invention is to provide a suitable machine for pulverizing iron ore in a dry state, tobc used for a lining or fine for puddling or boiling-furas hard as possible.)

pulverizatiom' but. of late years the said invention has vgone into very general use, andthe fixi'ngf as now used, consists of pulverized iron tire, either with or without thesadniixture of other materials, made into a pasty mass, and applied in the form of plaster. The

introduction of said McDonalNs invention into conlmon and' very general usent once created a demand for a machine to pulverize. ore, vfor the purpose above mentioned. l v 1t is essential, in order to form anadhesive past'y' mass from the pnlverized ore, that a portion of the `o1'e, atleast, be ground very'tine. Stamping-machines and crushing-machines of various kindswere first tried,"

all of which, however; failed to pnlverizc vthe ore to a sucient degree of fineness to make itadhesive; but when our machine was introduced, it was found to obviate, completely, this defect in all priormachines which had been used for the same purpose, and it has since been very extensively adopted, and is now in use in all, or nearly all iron nianfactories which use the invention of McDonald, or' any similar process .for lin- 'ing furnac es.` Our machine is constructed to operate on the same general principle as the old arastra,*"i1ong in use in gold-mining' regions for crushing quartz-ore in a' wet state, and of other machines of the same class, that have more recently been n`vented for similar purposes; but, in order to adapt our machine to the new use' of pulverzing iron ore in a dry state, we have made certain improvements, which are hereinafter described.

To the wheelsN N, which are made very heavy,. are attached rims'of chilled or hardened iron, (made These rims we cast in sections, 1 2. 34, and on the inner side ofe'ach section are two dovetails, extending across the inner surface of the4 rini,'which'are fitted into corresponding grooves inthe peripheries of the wheels, `so that when said rims become worn by use, they may be' easily removed, and new ones substituted.

Itis manifest, however, tlnrt the rim-of hard metal may be made all in one piece, insteadv of being madev in sections, and instead :of being attached to the main wheel by dovetailconnections, 'as described, may' be attached by other equivalent means, so as t'o be easily removed and replaced.

The pan or hopper B, in which the wheels revolve, is made dish-shaped, flaring ont at the top,.and may be varied in depth, as required.

In the center, where the journal on which the up; and thek hopper as to render them yunfit fornse, and right shaft rests, -it is raised some distance above the thus destroy thenost'expensive parts of the machine; bottom,`on'wleh theoreriscrushed and ground. but by means .of said detachable rims and track, we
