IMPROMENIQENTVIN COFFEEAAND SPICE MILLS.

Specification formiugpurt of Letters Patent No. 85.135. dated Septembrr l,1e`CS.

the following to be a full, clear, andiexact dea scription of the same, reference being `had to u .the accompanying drawings and the letters and gures'marked thereomwhich form a part of this specication, and in which- A Figureyl represents a top or plan view of my said mill; Fig. 2,\a side elevation of the same; Fig. 3, a vertical sectional ,view at the line x, in l. i

The nature of my invention consists in the construction of the three hoppers, as herein-- after described, and inthe construction of the bed-plate on which the hoppers rest, with the three openingsand shells, or outside grinders, so as to make a iirm, compact, combined mill,

\ with threeseparate grinding-mills, all driven from the same drive-wheel.

To enable those skilled in the art to understand how to manufacture and use my invention, I will proceed to" describe the same with particularity. A

'The same letters of reference refer to the corresponding parts in the different-figures.

In theaccompanyingdrawings, A represents three hoppers, all c'ast in one casting, so as to make a more solid and substaitial mill than when made separate `and fastened together, and is also less expensive to manufacture. One hopper, being intended for grinding coffee, is iliade as large as the'other ,two, oneof which is intended for grinding pepper and one for grinding spice.

B represents a bed-piece, which is cast with threecylinders, C, the inside of which are cast rough for grinding purposes, and conical, as

shown in a sectional view of one of them in Fignv. D\.jis'abox`,mad e of tin or other suitable material, on which the bed-piece B rests, and

it is divided into three compartments by the i partitions E. There is a drawer,F, for each of these compartments, each drawer being put in from a different side of the box D. By this arrangement no side of the box is materially weakened by the introduction of the drawers through 'Lthenr There is an arclrpiece, H, cast with three arms, I I I, in which the grind` the same time grind line.

`er-shafts have their bearings. The 'ends of the arch H pass down to the edge of the hopper A, and are firm] y secured thereto by the bolts J. Said bolts also pass down through the bed-piece B vand iirmly into the nuts attached to the box D, thereby fastening the hoppers, the bed-piece, and box D securely to gether. There is a rim, a, around the edge of the openings in the bed`piece B, above the cylinders C, and the lower edge of the hoppers A are beveled off so as to fit against said rims, as clearly shown in Fig. 3. These rims serve to keep the hoppers in place, and at the same time they make no impediment to the coffee or spice flowing down into the cylinder below.

K are grinding-cones, and they are cast with arough surface for grinding. The creases therein are made coarse at the top and fine toward thebottom, so as to grind faster, and at The creases may be parallel or crossed, as desired.

The spindles L and M are cast with the core and also the agitator O, which extends up into the hopper and agitates the contents there of, and causes it to feed regularly to the grindA ing-cone.

P is a cross-piece, one end of which rests in a loop formed by the wire Q suspended from the bed-piece B, the other end resting in a rod, R, which can be shortened by the nut S. The spindle M of the grinding-cone B has a step in the cross-piece l?, and the step is raised and lowered, which regulates the cone K to make it grind tine or coarse, by raising or lowering` the rod B, as above described. I cast the grinding-cones K with the base nearly as small as the top, so that no part of the grinding-sur face' is far from the perpendicular axial line drawn through the center, so that it will require less power to grind, and when Iwish to increase the grinding-surface I simply cast a longer cone.

The mainy driving-shaft T of the mill has a bearing in the arch H, and a step on the bedpiece B; or it may pass through the bed-piece B, having a bearing therein.

The small drive-wheel U' is cast with the shaft T, and the ,crank V is screwed on the end ofthe shaft. The drive-wheelU engages with the three cog-wheels of the shafts L L L, so that by turning the crank Vthe three mills are put in operation. The drive-wheel U is yoi" the bed-piece B, near its edge, for the top edge of the box D to rest against, so that it will be held more securely in place.

Having thus fully described the construetion and use ofmy invention, I will now specify what I claim and desire to secure by Letters Patentf l. The hoppers A A A, east in one piece, Substantially as herein described.

2. In combination with the hoppers A A A, when cast in one piece, the bed-plate B, and grindingeylinders C, substantially as herein described.

3. The box E, and drawers F, in combination Withhe bed-plate B. and grinding-@lina ders C, Substantially as herein described.
