I do hereby declare "the followingtobe' a full,

clear, and exact description thereof, reference being had to the accompanying drawing, form- I as at f, for the passage of, or made to rest ing a part of this specification, in which- 1 Figure 1 is a vertical section of a coffee-mill embodying my invention. view of the cover, and Fig. 31s aperspective view of the hopper.

Like letters refer to like parts whenever they occur.

My invention relates to the construction of cofl'ee and spice mills in such manner that the hopper is inclosed by the box, and may be closed in turn by a sliding gate or cover, whereby a compact and neat mill is obtained.

I will now proceed to describe my invention with reference to the accompanying drawing, so that others skilled in the art may construct and use the same.

A indicates the box, with its drawer B, of any suitable construction. The top 0 of the box is cut away, so that the hopper may be suspended therein, by means of a projecting To facilitate the suspension of the hopper, I preferably bevel the opening in top 0 to correspond with the curve of the hopper, as shown at c. This, also, will diminish the liability of the splitting of the wood when the screws which secure the cover are. introduced, (when a cover is used and secured as shown.) D represents the hopper or grinding-shell, provided with a flange or lugs, d, by which it is suspended in the box A. The hopper is fastened down, and also prevented from turning, by the screws g. The hopper has the usual grinding-face, d, and a series of projections or points, 0, which I provide for the purpose of taking hold upon the beveled edge 0 of the top 0, to assist in preventing any movement of the hopper. The

points, if sufficiently numerous, will of them selves prevent a change of position of the hopper, so that screws may be omitted. This will be found the cheapest and most conven- E is the ient way of suspending the hopper.

Fig. 2 is an under cover, having a'central opening'for the passage of the shank of 'thegrinding-nut, anda sunken or recessed" rim for the accommodation "of the lugs d or the flange ofthe hopper, so

that the lower edge of thecover rests evenly upon the top'O, and at the same time binds upon the hopper. This cover Eris provided with a sliding gate ordoor,'F, which is pierced,

against, the shank; of the grinding-nut, upon which it turns or bears, said gate F resting,

by its lower edge, upon the upper edge of the hopper, and sliding or moving within or without the cover E, so as to be out of the way when the opening in the cover is unclosed. G represents the grinding-nut, having a tapering shank, H, which passes through the cover, projecting portion of gate F, and the crank, and is secured above by the usual tighteningnut I.

The devices are put together as follows The cover and gate are placed upon the hopper, the shank of the grindingnut passed through the hopper, cover, and crank, and secured by the. tightening nut. The lugs or screw-openings in the flange of the hopper are made to register with those in the cover, after which the operative parts are dropped into the opening in the top of the cured by a single set of screws, which pass through the cover and lugs or flange of the hopper. The projecting points on the outside of the hopper will bite into the top of the box, and as the cover binds upon the upper edge of the hopper, these will, of themselves, if sufficiently numerous, be suflicient to prevent any movement of the hopper, so that, if desired, the screws need not pass through the flange of the hopper.

The hopper may be suspended, as shown, and the cover replaced by a bridge, to support the shank of the grinding-nut. The grinding shell or hopper and the cover may be secured by a separate set of screws. The lower part of the grinding-shell may be formed with lugs or projections, to guide and steady the grinding-nut.

Among the advantages of my invention are the simplicity of construction, and the readibox, and seness with which the several parts and the box Parents-fission.

may" be -adjusted orset up, whereby" timek-an'd labor are saved, and a serviceable article pmduced.

Having thus described my invention,,.w hat;.l
