IMPROVEMENT IN CIDERM| LLS.

Specification formingpart of Letters Patent No. 9,972, dated August 30, i853 Reissue No. l,703, dated October 11, 1864. f'

To all whom it may concern Be it knownthat JOHN KRAUSER, of Reading, in the county of Berks and State of Pennsylvania, did invent a new and useful Improvement in'Oider-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a plan or top view of the machine with its hopper and side casing removed,

so as to exhibit the working parts ofthe machine to a better advantage. Fig. 2 is a vertical longitudinal section taken in the line a a of Figa n portion of the hopperremoved, so as to expose to view the cylinder;

v Similar letters indicate the same parts wherever they occur on the drawings. v

C: represents lthe grinding-cylinder, armed with two kinds of teeth, one variety being shown in plan by Fig. 4 and in perspective by Fig. 5, the other kind being shown in a similar manner by Figs. 6 and 7. These teeth are arranged in a spiralv form upon the exterior of the cylinder, and are so combined that in the direction from a to c, Fig. 1, they alternate each other; but in the direction from c to d they form rows of a similar kind.

Cylinder C is mounted upon a shaft, o, and receives its motion from the crank-shaft o' by means of the gearwheels-` as shown in Figs. 1 and 2. The band-wheels f f are secured upon their shafts and communicate with each other by means of a belt. Upon the shafto" are keyed two eccentrics, c and o", which revolve' within vertical slots cut in the pistons or plungers P and P', to which theyl communicate an alternating reciprocating movement when the machine is in operation. The front ends of these pistons slide upon the upper surface of the bed-piece H, and their other crank may be attached to the opposite end of said rslial`t,it` desired; or,if it be desired Fig. 3 is a rear elevation with ashown.

to operate the machine by other than handpower, la pulley may be substituted for the crank. K A

In Figs. 2 and 3, a. a indicate the sides ot' the hopper for containing the material to .be ground or crushed. This hopper, it will be observed, is not placed over the. top of the cylinder, but rather to one side of it, so as to convey the fruit directly upon`the top of the front ends of the pistons P and bed-piece H.

By this arrangement of parts it will be perceived that as oneof the pistons is draw backlb'y the eccentric a cell or space is forme between the end of the piston and the cylin' der, into which the apples fall from the hopper. By lhaving the,apples thus delivered upon the end of the piston they are more or less kept in` motion lby the. movement of the piston, and thus prevented from becoming choked in the throat of the hopper. The apples in the space between theend of the piston and the cylinder are prevented from being shoved upward away from contact with the cylinder by the pressure of the superincumbent mass above them, and thus held firmly in place while being pressed by the end of the piston up against the surface of the cylinder. By this arrangement the apples are --both crushed and ground at one and the same operation, the crushing being performed by the forward movement ot' vthe pistons, and the grinding by the revolving cylinder.

In Fig. 8 a modification of the machine is In this case the crushing devices, instead of being arranged to slide or move in a direct line, as in Figs. 1 and 2, are pivoted,` as at H', in such away as to produce an oscillating or swinging motion. 'In this case the eccentrics are placed in the rear of the crusher,` and are connected therewith by means of a suitable yoke.

Fig. 9 represents still another modification, diiering from the preceding in the form or shape of the crushcrs, and in being pivoted at the bottom instead. of the top, the eccentrica being placed in their rear and connected by proper yokes in any suitable manner. n

In all cases a concave, k', is affixed under neaththe bed-piece 1I. This concave, 7J,i

BEST AVAILABLE COPY n armed'on its inner surface withv angular 'ribs or projections arranged parallel withthe shaft o, and the whole'iis mounted/upon any frame y of suitable size and shape. l

The operation of the machine is so apparent that any further or\ detailed statement thereof 'is deemed unnecessary.

Having thus described said invention, what A I claim as new therein, and desire to secure A' by Letters Patent, is'

'l'. So locating the hopper as that lthe sub:

stance tobe ground shall vbe delivered uponthat portion of the piston or erusher which shall be within the hopper when thrust forward, or into the space formed' by the withdrawal of the same when thrown backward.

2. Operating the pistons or concaves of a eider-mil1 by means of eccentrica, whether said pistons .be arranged, es in Figs. 1 and 2, Ato move in a straight line, or be pivoted at top or-bottoln, as in Figs. '8 and 9. A

3. The concave k', arranged to operate iu combination with the pistons P. or with the 4coneaves d, as and for the purposes set forth.
