LUCIEN POULIN, OF GUNDERSON, MONTANA.
GRlNDlNG-MILL.
SPECIFICATION forming part of Letters Patent No. 443,295, dated December 23, 1890.
Application filed October l, 1890. Serial No. 366,731. (No model.)
useful Improvements in Grinding-Mills, of
which the following is a specification, reference being had therein to the accompanying drawings.
The object of my invention is the construction of a grinding-mill forthe purpose of coinminuting auriferous and argentiferous rock after the same has been partly reduced by other machinery, and I attain my object by the mechanism hereinafter described.
In the drawings, Figure 1 is a side elevation of my mill. Fig. 2 is a vertical section of the same. Fig. 3 is a detail of the upper grinding-surface of the shell. Fig. 4 is a detail of the lower grinding-surface of the shell. Fig. 5 is a detail of the upper grinding-surface of the core, and Fig. 6 is a detail of the under grinding-surface of the core.
Like letters and figures refer to the same parts throughout the several views.
The grinding-surfaces consist of the inner surfaces of a double cone-shaped shell formed by the parts 7 and S and the outer approximating surfaces of a hollow double coneshaped core formed by the parts 10 and 11, susceptible of being revolved in opposite directions. The lower portion of the shell is seated upon the annular shoulder 34 at' seat 35, and is supplied with a rim 9, which may be cast integrally therewith, projecting above the upper. portion of the shell and forming a Zone inclosing the point of junction of the upper and lower portions of the shell. The annular shoulder Si, being subject to wear, should be cast separately and attached by any suitable means, so that it may be removed when worn out. The upper portion of the shell 7 its within the rim 9 as a lid or cover, forming a joint sufficiently tight to prevent the escape of the material which is being ground, and holds to and revolves the lower portion of the shell 8 by means of the flanges 5o f upon the inner side of rim 9, which enter slots f', Fig. 3, in the upper portion of the shell for that purpose. The upper and lower portions of the core are rigidly attached at their edges. They are cast separately for convenience, and the core is hollow, so as to render it of light weight. Of course it may be cast in one piece and solid. The upper portion of the shell is provided on its inner concave side, radiating from its top, with grinding-fu rrows a a, a a, extending outwardly and downward, being deeper at the top and' gradually disappearing, so as to leave the lower and outer portion of this concave surface smooth. The opposing and approximating upper portion of the core 10 is supplied with similar grinding-furrows a a a a on its convex surface, similarly located to those on the upper portion of the shell and gradually disappearing toward the outer edge. The lower portion of the shell S and of the opposing and approximating lower portion of cone 11 are similarly supplied with grinding-furrows h Z) h h and h h b b,except that these grinding-furrows are most prominent at the outer edge on both shell and core and gradually disappear downwardly and inwardly, leaving smooth surfaces as the center or top is approached. Thus the opposing approximating surfaces of shell and core conjoin to grind the material passing between them. By this arrangement of the grinding-ridges the material is subjected to the action twice, once immediately on entering between the upper grinding-surfaces and again on commencing the passage between the lower grinding-surfaces. The core is attached by its upper portion at the apex thereof to the coresliaft 12, and is suspended thereby within the shell. The core-shaft has its bearings upon head A, which sustains the shaft vertically and in the supporting-fingers 16 and 17 of the block 13, extending inwardly over the center of the frame-bed B. The block 13 is attached to and held between the standards 14: and 14', fixed to the side of the frame-bed at 15 and 15. The gear-wheel 18 is rigidly attached to this shaft between its bearings 16 and 17. The shell is attached by its upper portion at the apex thereof to the sleeve 19 by a band 37, which the sleeve enters.
rigidly held in place by bars g, connecting the band and terminating rim 3S of the upper portion of the shell 7, thus forming an annular opening e between the terminating rim 3S and The band 37 is upon the frame-bed ll.
band 37 for the admission of the material to be ground. A small hopper 30 surmounts the terminating rim of the upper portion of the shell T. The lower portion of the shell has at its base the hollow gudgeon 20, iixed inthe annular shoulder 3l and revolving` in the vertically-adjustable box 2l, located in the base of the 'frame-bed, upon which the annular shoulder 25- has its bem-ing. The annular shoulder 3l carries the boss d', liig. l, which engages in slot (Z in gudgeon 20, for the purpose of strengthening the fastening of the gudgeon to the annular shoulder. The sleeve 19 carries the gear-wheel 22 between the fingers 2li and 2l ot' the block13. rThe bearings of sleeve 10 are in fingers 225 and 2i of bloei; 13 and the gear-wheel 22 resting and revolving upon linger 2l. lhe horizontal gearwheels 1S and 22 mesh with a vertical gearwheel 25 upon horizontal driving-shaft 2G, having its bearings upon either horn of the U-shapcd supports 27, resting on the single standard 2S, which has its support and base Between the horns 27 upon driving-shaft 2G is the driving-pulley 2t). The U-shaped support for bearings of horizontal driving-shaft 26 is placed on its single supporting-standard alittle ot'f its center to bring the inner bearing as near pos sible to vertical gear-wheel 25, which is the point at which power is to be applied.
The box 2l is located in the frame-bed between cross-braces and 32 (shown in section in liig. 2) and the legs of a bifurcated wedge-shaped key 30, one leg of which is shown in lfig. 2, which rests upon cross-braces 32 and 32 at right angles with the crossbraces in mortises 36 and 3G prepared for its reception. There are projections on either side of box 2l, which conform to and rest upon the upper and beveled side of the wedge-shaped key 30, so that driving thekey inwardly raises the box and with it the shell, and withdrawing it permits the box and shell to be lowered by gravity. The object of having this box 21 vertically adjustable is the adjustment of the lower portion of the shell S with reference to the lower portion of core 11, so that the grinding-surfaces thereon may be regulated in their separating distance according to the wish of the operator.
Power being applied to the driving-pulley 2f), it is communicated by the gearing heretofore described to the core-shaft and sleeve, respectively, carrying the core and shell, revolving them in opposite directions. 'lhe partially-crushed rock to be operated upon, interininglcd with water, enters between the grindiiig-surfaees through the annular opening e and, following the direction of the arrows in Fig. 2, passes downward between the grinding-surfaces and is discharged through the hollow gndgeon 20, colnminuted to the extent desired.
Having thus fully described my invention, what l claim, and desire to secure by Letters latent, is-
l. ln a grinding mill, a double conc-shaped shell having on the inner side of its upper portion grinding-furrows extending from its top outwardly and downwardly, deeper at the top and gradually disappearing so as to leave the lower and outer portion ofthe concave surface smooth, and on the inner concave side of the lower portion of the shell similar grinding-furrows, deeper at the outer edge thereof and gradually disappearing downwardl y and inwardly, in combination with a double cone-shaped core located within the shell, having grinding-furrows on the convex surfaces of its upper and lower port-ions similar to those upon the shell, lforming opposing and approximating grinding-surfaces of shell and core operating in conjunction to grind material passing between them, the shell and core being susceptible of revolution in opposite directions, as and for the purposes specilied.
2. ln a grinding-mill, the herein-described double cone-shaped shell and core, having on the upper portions of the grinding-surfaces thereof opposingand approximating grindingfurrows extending from their top outwardly and downwardly, deeper at the top and gradually disappeari ng so as to leave the lower and outer parts of both grinding-surfaces smooth, and similargrin ding-furrows on the lower portions thereof, deeper at their outer edge and gradually disappearing downwardly and inwardly, in combination with the shaft 12, head A, block 13, supporti11g-standards 14.- 14:', gearwheel 18, sleeve 1t), gear-wheel 22, vertical gear-wheel 25, driving-shaft 2li, and drivingpulley 29, having the U-shaped supports 27 resting on the standard 2S, as and for the purposes specified.
3. 1n a grinding-mill, the heroin-described double cone-shaped shell and core, having on the upper portions ol the grinding-surfaces thereof opposing and approxinmting grinding-furrows extending from their top outwardly and downwardly, deeper at the top and gradually disappearing so as to leave the lower and outer part of both grindingsurfaces smooth, and similar grinding-furrows on the lower portions thereof, deeper at their outer edge and gradually disappearing downwardly and inwardly, in combination with the annular shoulder 3l, forming a seat for the lower portion of the shell, the vertically-adj ustable box 2l, and wedge 3U, operating as and for the purpose specified.
