CRUSHING OR GRINDING MACHlNE.

SPECIFICATION forming-part of Letters Patent No. 507,140, dated October 24, 1893. Application filed September 27, 1892. Serial No. 447.077. (N0 model.)

To all whom it may concern.-

, Be it known that I, CORNELIUS KIMPLEN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Crushing or Grinding Machines, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation. Fig. 2 is a top or plan view of the lower bed-plate. Fig. 3 is a central longitudinal vertical section. Fig. 4 is an enlarged detail, being a central longitudinal vertical section of the grinding mechanism. Fig. 5 is an enlarged detail, being a back view of one of the grinding sections. Fig. 6 is a cross section on line w-x of Fig. 5; and Fig. 7 is an enlarged detail,

showing one of the spoons and the method of securing it to the running-head of the mill.

My invention relates to machines for crushing or grinding stone, bone, or other similar substances, and is in many respects similar to the mill shown in Patent No. 281,887, granted to me July 24, 1883.

I The object of my invention is to improve the construction and operation of mills of the above described class, which object I accomplish as hereinafter specified and as illustrated in the drawings.

That which I regard as new will be pointed out in the claims.

In the drawings,1, indicates a bed-plate, which supports the various'parts of the machine. The bed-plate l is annular in shape, and is provided with a central cross bar 2, as best shown in Fig. 2. p 3, indicates a number of vertical columns which areplaced at suitable points upon the bed-plate 1, and support another bed-plate 4 in a horizontal position, as best shown in suitable bearings 16 and 17, resting upon th upper bed-plate 4. The bearing 16 is located Figs. 1 and 3. The columns 3 are preferably five in number, and are arranged as shown in Fig, 2. The bed-plate 1 is provided at a suitable point on its upper surface with a removable segment 5, which is of about half the thickness of the bed-plate.

6, indicates parallel bars, which at one end are secured to the removable segment 5 and extend across'the bed-plate, as best shown in Fig. 2, theirother ends moving in suitable bearings 7 secured to t-he-und-er side of the cross piece 20f the'bed plate 1. By thisconstruction, the segment 5 is adapted to be drawn away from the remainder of the bedplate in a straight line. In order to move the segment 5 to or from the bed-plate, the ends of the bars 6 adjacent to the segment 5 are cogged on their under sides to form racks, as best shown in Fig. 5.

8, indicates a cogged pinion, two of which are mounted upon a shaft 9 mounted in suitable bearings in the bed-plate 1, and extending across the bed-plate in a direction at right angles to the bars 6. The pinions 8 are so placed that one of them will intermesh with the rack upon each bar 6.

The shaft 9 is made of such length that its ends will project a short distance beyond the periphery of the bed-plate 1, and such projecting ends are squared, as shown at 10 in Fig. 1. By applying a wrench or lever 11 (see Fig. 3) to one or both of the ends of the shaft 9, the shaft may be rotated, therebyl moving the segment 5 into or out of its place in the bed-plate 1, as the case may be. I

One of the columns 3 is mounted upon the removable segment 5 of the bedplate, as shown in the-drawings, and that portion, 12, of the upper bed-plate 4 immediately over the removable segment5 is detached from the remainder of the upper bed-plate 4 and rests upon the column 3 upon said segment 5, as best shown in Fig. 1. By this construction, when the segment 5 is moved, the segment 12 of the bed-plate 4 willalso be similarly moved. When the machine is being operated, the segment 5 may be rigidly secured in place by means of bolts 13, and the segment 12 may be firmly secured in place by means of bolts which pass through cars 14, cast at suitable points in the bed-plate 4 and segment 12, as

shown in Fig. 1.

15, indicates a shaft, which is mounted in over the column 3 which rests upon the removable segment 5, and the bearing 17 is 10- cated at a diametrically opposite point upon i I i ferred to, being somewhat circular. A delivery tube 52 is provided, which opens into the upper part of the casing 51.

53, indicates a cover which fits over a suitable opening in the upper part of the casing, through which access may be had to the interior of the casing. Thecasing is of somewhat greater diameter than the running-head 33, and is adapted to receive the powdered stone or other substance after it has passed from the grinding sections 35. The powdered substance will then be carried by centrifugal force around the interior of the casing 51 to the outlet tube 52.

In order to cause the crushed substance to move more freely around the casing 51 to the outlet tube 52, the running-head 33 is provided on its periphery with spoons 53, which are radially secured in the running head by means of plates 54 which are arranged in mortises 54 in the inner face of the runninghead, as best shown in Fig. 7. If desired, the spoons 53 and plates 54 may be made separate from each other, but I prefer to make them integral with each other, as shown in Fig. 7. Besides mortising the plates 54 in the running-head 33, they may be further secured therein by means of bolts 55, as shown.

When the running-head is in operation, the spoons 53 will aid in carrying the crushed or ground substance around the interior of the casing 51, and will serve to expel any unbroken fragments or pieces which may have passed through the grinding plates without being crushed. They will also cause a draft through the casing, by which all dust will be carried out.

The shaft 15 is provided with a pulley 56,

by means of which it may be rotated, andv with a fly wheel 57, as shown in Fig. 3.

The movable bearing 23 and weight 62 perm'it the grinding plates to be forced apart, as would be necessary if some extraordinarily hard body should fall into the hopper, to prevent breakage of the mill, substantially as described in my former patent hereinbefore referred to.

That which I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a frame 47, an inner crushing plate 48 and an outer grinding ring 49, of a supporting head 33 having a flange 43, an inner crushing plate 34 having a peripheral flange 37, an outer grinding ring having a recessed part with which interlock the said flanges on the supporting head and crushing plate, and devices for securing the outer. grinding ring to the supporting head to clamp the inner crushing plate to said supporting head, substantially as described.
