MORTAR-BED FOR STAMP-BATTERIES.

SPECIFICATION forming part of Letters Patent No. 310,296, dated January 6, 1885.

Application filed May 2'7, 1884. (No model.)

To all whom it may concern.-

Be it known that we, Gnonen Massu and FILoMENo FERNANDEZ, of Mazatlan, in the Republic of Mexico, have invented certain Improvements in Mortar-Beds for StampBatteries; and we hereby declare the following to be a full, clear, and exact description thereof.

()ur invention relates to the class of orecrushing devices or stamp-batteries, and more particularly to certain new and useful improvements in the mortar-beds thereof, whether of single or double discharge or dry or wet crushing mortars.

Our invention consists in improved means for adjusting the screens of mortar beds, whereby they are adapted to be raised and lowered according to the state of the dies, whether new or worn out, all of which we shall hereinafter fully describe and claim.

The object of our invention is to so arrange the screens that they may be raised for new dies or lowered as the said dies wear out, in

. above the dies, and that the discharge of the pulp may be effected to the best advantage, as we shall presently fully indicate.

Referring to the accompanying drawings, Figure 1 is a sectional elevation of our mortar-bed, taken on the line 00 at, Fig. 2, the die and stamp-head being in elevation. a plan of the mortar-bed. Fig. 3 is a front view of mortar-bed. Fig. 4 is a front view of movable or adjustable plate with screen,brackets, trough, &c. Fig. 5 is a section through line 3 3 Fig. 4. Fig. 6 is a top view of Fig. 4.

Z is the mortar-bed, containing the die 2. Y is the frame of the battery; X, the stamp, and IV the stamp-stem.

By reference to Fig. 1 it will be seen that we leave the n1ortarbed open in front at a, the mortar here shown having a single discharge. In case of a double discharge the mortar would be left open both in front and back, and all the parts,which we shall herein describe as applicable to the single discharge,

would have to be duplicated for a double-discharge battery. In the open front of the mortar we leave but a toe, A, across it to hold the dies in place. The screen 0 rests on the top edge of a wrought-iron movable or adjustable plate, B, which is dressed or faced v on the Fig. 2 is planer, as also 'is the face Q of mortar-bed. Both the screen and movable plate are held water-tight against the mortar-bed by the following means:

First. By two wedges, F, Figs. 1, 3, two angle-irons, D, and two cast-iron slides or guides, I, planed and riveted to the jaws B, Fig. 2, extending from the mortar and to the housing, which housing may be made either of sheetiron or cast together with mortar-bed proper. In order to secure the tightening of the wedges F equally against the screen and movable plate, the latter is provided with two cast-iron liners, K, (see Figs. 4 and 5,)planed and riveted to the plate, in order to make up for the difference of thickness between the frame of the screen and the movable plate.

Second. By three screws, G, fitted with small wheels or spurs 9, Fig. 1. These screws work into a cast-iron Crosspiece, L, held between the projecting jaws R of mortar, Fig. 3.

By means of a yoke, T, andscrew S, working through a nut, M, fitted in a bracket, V, the movable plate and screen can be lowered or raised. The bracketVis open in front and provided with a pin to prevent the yoke from falling off, and the extremities of the legs of yoke are made to fit into two cast-iron brackets, H, Figs. 3 and 6, riveted to the movable plate, Fig. 4. Said plate bears also in its center a small wrought-iron bracket, I, and wedge i,to tighten the screen against the plate. (See Figs. 6, 5.) After the screen has been regulated according to height of dies, the yoke, nut, and bracket can be taken out by removing the above-namedparts,tobe replaced again when a new setting of the screen is required. The trough N is riveted to movable plate to receive the pulp, which is afterward delivered to tanks through round cast-iron spout O.

In Fig. 1 the screen is represented as being at a proper height above the die, and the oband yoke for raising and lowering said screen, substantially as and for the purpose herein described.

2. The combination, in an ore-crushing battery or stamp-mill, of the mortar-bed,open or cut away at its discharge, a screen at said discharge, and a screw and yoke for raising and lowering said screen,whereby its height above the dies in the mortar-bed may be maintained, whether said dies be new or worn, substantially as described.

3. The combination, in an ore-crushing bat tery or stamp-mill, of a mortar-bed, Z, open 1 at its discharge a, and having a toe, A, across the discharge, the die a, a suitable screen covering thedischarge, and'a' screw and yoke for raising or lowering it in the open space a, substantially as described.

4. The combination, in an ore-crushing battery or stamp-mill, oia mortar-bed, Z, die c, the movable plate B, and screen 0, secured to its top,wedges F, angle-ironsD,and guides P, for holding said plate and screen against the mortar and frame of the battery, and a screw and yoke for raising and lowering them, substantially as and for the purpose herein described.

5. In an ore-crushing battery or stamp =mill,

a mortar-bed, Z, having projecting arms It and die 2 the movable plate 13, having liners or strips K, and the screen 0, secured to the top of plate, in combination with the means for holding said plate and screen in place, consisting of the wedges F, angle-irons D,'and guides P, riveted to arms R and to the housing of the mill, the tightening-screws G, and cross-piece L, said screws having wheels or spurs 9, bearing against said plate B, substantially as described;

6. The combination, in an ore-crushing battery or stamp-mill, of a mortaubed, Z, die a, the movable plate B, and screen 0, secured to its top, means for holding said plate and screen against the mortar-bed over its dis charge, and the mechanism for raising and lowering them, consisting of the yoke T, bearings or brackets H on the plate B, the screw S, nut M, and bracket V, secured to the frame ,of the mill, substantially as herein described.

In witness whereof we have hereunto set our hands.
