Specilication forming part of Letters Patent No. @3,7%3, dated February 23, 1864.

T0 @ZZ whom t may oon/cern,.-

Be it known that I, GEORGE S. RUs'r, of Chester, county of Randolph, State of Illinois, have invented a new and Improved Ap ple-Mill; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a vertical longitudinal section through the center of my improved mill. Fig. 2 is a top View of the same. Fig. 3 is an end View showing the concaves in two positions.

Similar letters of reference indicate corresponding parts in the three gures.

This invention relates 'to improvements in hanging and adjusting the concaves of that class of apple-mills wherein two or more alternately vibrating concaves are employed in conjunction with a rotary drum for reducing the apples.

rIhe objectof my invention is to hang the" concaves over the rotating drum in such manner that a greater vibration or swinging motion can be given to their rear or discharging ends for the purpose of keeping the crushed mass under them until it is linely reduced, and then allowing the pomace to escape more freely after it has been properly reduced, as will be hereinafter described.

It also has for its object a novel means for adjusting the concaves to increase or diminish their vibration, and also for grinding and crushing iine or coarse, as may be desired.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe its construction and operation.

The frame A, rotating toothed grinder B, driving-shaft (l, and gearing a b are all conconstructed and arranged precisely in thc manner described in my corn-Sheller and combined straw-cutter and corn-sheller applications which accompany this. lhese parts above referred to are constructed and arranged with a view to their being used in connection with the several devices which are added in the conversion from one hind of maof arms or eyebolts d cl, the eyes of which receive the bar c and form pivotal connections of the concaves with said bar. Two eyebolts are used for cach concave, and these bolts d cl are screwed into the concaves before they are slipped on their supporting-bar. This bar is then introduced into the slotted guides e c in the sides of the frame A, which guides are adapted for receiving springs for holding the bar c down in its bearings when it is desired to employ springs.

The lower ends of the pivoted arms d d are secured into the upper surfaces of the concaves D D at a point which is near their rear or lower ends. The concaves are thus suspended by pivoted arms above and on one side ofthe axis of the rot-ating grinder B, as shown in Figs. l and 3, so that by vibrating these concaves their' serrated lower or acting surfaces will be made to approach and recede from the grinder, and thus to crush the apples on the surface of said grinder during the rotation thereof. The effect-of this mode of hanging the concaves is to give to them a rocking motion about their fulcrum-bar c, and as their forward ends rise their rear ends move toward the surface of the grinder B, and vice versa 5 hence it will be seen that the rear ends of the concaves will press the crushed mass forward on the rotating grinderas their upper ends rise, and thus keep the pomace between the crushing and grindiugsurtaces as long as possible.

rIhe forward ends ofthe concaves D D are pivoted in asuitable mannerto the ends of rods g g, the opposite ends of which are pivoted to the ends of a vibrating lever, G, that receives its motion from the drivin g-cranh shaft C through the medium of a connecting-rod, It, as shown in Fig. 2. By this mode of vibrating the concaves they receive an alternate motion, the forward end of one rising as -the forward end of the other is depressed. This alternate motion of the concaves has been found well suited to the purpose of crushing the apples on a rotating drum, as the crushed mass is pressed during the operation from one chine to another. rlhe concaves D D in this end toward the other of the drum, and is thus machine are constructed so that their curved constantly acted upon by one or the other of surfaces are adapted to werk in connection thc concaves. Where such concaveshavebeen with a rotatiu g toothed grinder, B, of the form pivoted directly to a bar-i. e., by a barpassing of ahyperboloid.
