MILL FOR GRINDING OR PRESSING COFFEE, SPICE, SLG.

SPECIFICATION forming part of Letters Patent No. 310,336, dated January 6, 1885.

Application filed February '23, 1884. (No model.) Patented in Germany January 1, 1884, No. 28,118; in Belgium January 4, 18S4, No. 63,757; in France January 5, 1884, No. 159,571; in England January 1S, 1884, No. 1,711; in Austria-Hungary February 23, 1&4, No.1,028 and No. 7,957; in Sweden March 26, 1884, and in Norway May 16, 1884, No. 2-27.

` sic, in the Kingdom of Saxony, Germany,

have invented a new and useful Improvement in Mills for Grinding or Crushing Coffee, Spice, Fruit, and other Articles, of which the following is a speciiication.

My invention relates to mills for grinding or crushing coffee-beans, spices, fruit, and other articles, and has for its object to construct a simple apparatus by which these operations may be carried out eflicientlywithout requiring much power.

In describing the invention, reference will be made to the accompanying drawings, in which Figure lis partly a vertical section and partly an elevation, Fig. 2 a horizontal scction, and Fig. 3 an end elevation, partly in section, of an improved mill, while Fig. 4 shows the nature of the grinding-surfaces.

From a base-plate, a', extends up ward a stand, a, cast together or otherwise connected with the base-plate, which has also a pair of lugs, Z', adapted to receive between them'V a rectangular plate, 7c', in the vcenter of which may be formed a circular receptacle, k,said plate being introduced between the lugs i as far as to abut against the pins s. In this position the center of the circular receptacle k is placed perpendicularly under the center of the disk g, mounted at the lower end of the shaft c, and connected with a hand-lever, h. The under surface of the disk g and the bottom of the receptacle 7a may be provided with grooves, serrations, or ri dges,the shapeof which varies according to the nature of the material to be ground or crushed. The shaft c is held in the guide Z of the stand a, and is adapted to be lifted, with the disk g, by means of the helical spring f, placed between the bearing Z and the nut m, screwed to the upper end of the shaft c.

The disk g and shaft c may be cast together, or they may be connected as represented in the drawings.

Between the guide Z and the disk g are mounted the rods eZ, held at both ends in balland-socket joints, and arranged in such manner that on turning the disk g by means of the .lever Zi in the direction of the arrow the rods cZ, which are represented in Fig. 1 in a slanting position, are placed perpendicular, as may be seen in Fig. 3, whereby the distance between the bearing Z and the disk g is increasedthat is to say, the disk g is pressed downward until it comes almost in contact with the bottom of the receptacle 7a. On turning the lever ZL in the opposite direction the disk gis lifted out of the receptacle 7s by means of the spring f, and the rods d are replaced in their previous position. (Represented in Fig. l.)

The apparatus works as follows: The receptacle k is removed from the base-plate a and filled with the material to be ground or crushed, after which the receptacle is replaced between the lugs under the disk g, so as to rest against the pins s. Subsequently the disk gis turned down into the lled receptacle L, whereby its contents are ground or crushed.

For emptying the receptacle k the disk g is turned back and the receptacle k removed from the base-plate a.

What I claim is- 1. In grinding or crushing mills, the combination of a fixed plate, k', serving as a receptacle for the raw material, with a disk, g, and shaft c, adapted to receive simultaneous rectilinear and rotary motion, a fixed guide, Z, rods d, connected by ball-and-socket joints with the disk g and with the guide Z, and a helical spring, f, adapted to draw the disk g away from the plate k', substantially as described. y

2. In grinding or crushing mills, the combination of fixed plate Zo', forming a flanged receptacle, 7c, with a disk, g, and shaft c, guide Z, rods d, and spring f, substantially as described.

3. In grinding or crushing mills, the combination of xed plate k with disk g and shaft o, hand-lever h, guide Z, rods d', and spring f, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
