vIMPROVEMENT IN COMBINED ORE-CRUSHERS ND`AMALGAMATORS.

The Schedule referred lto in these Letters Patent and making part of the same.

To all whom yit may concern:

Be it known that I, LYMAN GRISWOLD, of Denver, in the county of Arapahoe, Colorado Territory, have invented a new and improved Combined Ore-Crusher and Amalgamator; and I do .hereby declare that t-he following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein had to the accompanying drawing forming part of? this speciiicatiou.

Figure l represents a side elevation, partly in section, of my improved crusber and amalgamator.

Figure 2 is a vertical transverse section of the same, takeri'on the plane ofthe line :c x, fig.`1.

Similar letters of reference indicate corresponding parts.

My invention relates to ore-crushers and amalgamators, and consists'in certain improvements, which will be first described in connection with all that is necessary to their full understanding, and then clearly pointed out in the claim.A

A in the drawing represents the case or box within 'which the cruslier-'dies B arel set up on the bottom a of the same.

The punches are secured to rods that pass through the trough-shaped cover b of the case, said punchesand rods being not shown-iu the drawing. y

The cover b of the case A is made double inclined, so that it is deeper along the middle than at the sides,

and serves-as a trough for the wat-er, by which the rods are lubricated and the ore moistened.

The holes in said trough for the rods are larger than the rods, to permit the water to enter the case.

The middle portion of the A is somewhat enlarged, as shown in iig. 2, so as to constitute the chute C for inserting the ore, and opposite to said chute, to receive the screenl).

The chute is formed in shape of a longitudinal hopper, extending from end toeud of the case, and has its inner side open near the'bottom, to discharge its contents into the case. t

The bottom of thechute is inclined for guiding the ore properly to the dies.

The ends of the chute are, by platesc c, kept a dis'- tance oi the ends ofthe case, so that the ore may be kept from the frames or levers used for clamping the amalgaInating-platcs, which are hereinafter described.

The screen D is secured in place by a frame, d, which is fastened by means of keys or wedges.

E E are the amalgainatingplates. They are secured in inclined positions to the inner sides of the case A, and extend from end to end oi' the same. They are preferably made oi'copperl Quicksilver is used in the case during the crushing process. l

The plate E under the bottom of 'the chute is connected with a longitudinal Vstrip or plate, F, which is, by means of swingingyokesg and wedges h, secured against the opening in the side of the case A.

By swinging aside the yokes the strip F, with its `plate E,can, by means of handles t', be readily removed.

The other platefE' slants off the inner face of 'the screen, and cau be taken out by'removing said screen.

The lower edges of both'plates-E E rest in grooved ribs j j, as shown, thev said ribs forming V-shaped projections for protecting the plates and preventing them from scouring.

The plates E E are held down by'rubber pads K, that are secured in or to the inclined arins l of vertically-adjustable frames G, the said frames being arranged at the ends .of the case, and connected-at their upper ends to pivoted levers-m m, by which the pads can be lifted o ii the plates. Y

Spring-catches o serve to hold the levers mmin'the lowered positions.

The plates c in the chute are i'or protecting the arms l, frames G, and pads It from the ore.

That sidev of thecase A, which is above the chute is made in form ot' aremovable plate, n, which is held in place by means of wedges and bolts. By its removal ready access can be had to the interior vofthe case.

The chute (l is'also made removable and secured in similar manner. The interior of the apparatus can thus be readily reached.

Similardevices heretofore made could not be opened at the sides, except by the removal oil. the screen, which is frequently insuicient to allow the clearing up and removal oi' broken dies, shoes, Sac.

Having thus describedl my invention,

I claim as new and desire to secure by Letters Patent- 1. rlhe elastic pads l.: k, secured to the slidin g frames G, and connected with the' levers m, substantially' as herein shown and. described.

2. The chute C, having its inner side open and bottom inclined, and the plates c c colnbinedas described with case A, for thev purpose specified.

3. The plate E, combined as described, with strip `14", yoke g, wedge h, and handle i, for the purposegol' securing or detaching the said plate, as' set forth.

' LYMAN GRISWOLD.
