ROCK-BREAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 510,800,'date d December 12,1893.

Application filed August 15,1292. Serial No. 443,065. (nomad) erence being had tothe accompanying drawings, in which Figure 1 is a longitudinal vertical section on line 1-1 of Fig. 2. a Fig. 2 is a horizontal section on line 2-2 of Fig. 1. Fig. 3 is a detail, being a partial sectional view on line 3 3 of Fig. 1. Fig. 4 is a perspective view of one of the face plates. Fig. 5 is an elevation of one side of the upper portion of the oscillating lever; and Fig. 6 is a detail, being a'view of the back of one of the face plates carried by the oscillating lever. My invention relates to machines for crushing ore or rock, and the object of my inventron is to improve the construction and operatron of machines of that class. I accomplish this object as hereinafter specified and as illustrated in the drawings.

In the drawings, the numeral 7 indicates the outer casing of the machine which is of suitable size and shape, and is formed or constructed with a central partition or wall 7, which may, if desired, terminate in a curved lower edge, as at 7". The levers 8 are vertically mounted in the casing 7 at opposite sides of the partition or wall 7 each lever having its upper end supported by trunnions 9 and 10 resting in suitable bearings at the upper portions of the casing and partition or wall. The lower portion of each lever S is preferably bifurcated, consisting of two parallel arms connected by cross ribs 11; but the lever may be made of a single piece if desired. By trunnioning the lever 8' as above described, it is adapted to be oscillated, as will be hereinafter set forth. The two sides of the upper portion of the lever 8 which are ninety degrees from the trunnions 9 and 10 are oppositely inclined, as shown in Fig. 1, and are provided with dove-tailed grooves 12, as best shown in Fig. 5.

13 indicates face plates, each of which is provided with a tongue 14 adapted to fit into the grooves 12 in the lever 8. The lower portionsof the grooves 12 are somewhat narrower than. the upper portions, to prevent the plates '13 from moving down too far. By this construction the plates 13 may be readily fitted in place on the lever 8.

15 indicates face plates which are mounted upon the upper portion of the casing 7, opposite the face platesl3. The inner'surfaces of, the face plates 15 are curved, being preferably of aboutthe shape shown in the drawings. The rear surface of each of the plates 15 is adapted to fit snugly against the inner surface of the casing ,7 at the point where it is adapted to be secured thereto, as shown in Figs. 1 and 3. Each of the face plates 15 is provided near its lower end with a dove-tailed groove 16, which extends vertically, as shown in Fig. 1. The grooves 16 are adapted to receive the dove-tailed heads of bolts 17, which pass through the side of the casing and carry nuts 18 upon their outer ends. By this construction, by tightening the nuts 18 upon the bolts 17, the plates 15 maybe tightly held in place on the casing.

19 indicates a lug formed on the back of each plate 15, which lug is provided with an inclined upper surface, as shown. The plates 15 are also provided with recesses 20 immediately above the lugs 19; the object. of which will be hereinafter set forth. The casing 7 is also provided with recesses 21, which are of such shape as to receive the lugs 19, and also to receive a nut 22 which is mounted upon a bolt 23, as shown in Fig. 1. The bolts 23 pass through the casing 7, projecting into the recesses 21. The lower edge of each nut 22 is inclined to conform to the inclination of the adjacent lug 19 upon which it is adapted to rest. By loosening the nut 18 on the bolt 17, and operating the bolt 23, the nut 22 will be moved upon its bolt, thereby moving in or out upon the lug 19. If the nut 22 is moved toward the plate 15, the plate may be raised a short distance, or if it is moved in the opposite direction it will force the plate 15 downward. By this construction the position of the plates 15 may be adjusted as desired to compensate for wear and to vary the operative position of said plates15 with relation plates 15 are preferably provided with staples to the plates 13 on the oscillatory lever. The

24 at theiiupper ends, adapted to receive hooks or other implements to facilitate their removal.

The plates 13 and 15 are so placed with relation to each other that by oscillating the lever 8 the stone or ore which may be thrown between them from above will be crushed, and will thence pass downward between them.

25 indicates chutes, the upper ends of which lie immediately beneath the face plates 13 and 15, their lower ends terminating at the outside of the casing 7.

The leversSare both oscillated by means of a single shaft 26, which is transversely mounted in the lower portion of the casing 7, and carries eccentrics 27 which are connected to the lower ends of the levers by connecting rods, as at 28. The shaft 26 may be rotated by any suitable mechanism, and through the medium of the eccentrics and connecting rods the levers 8 will be oscillated. By constructing the casing with the central partition or wall 7 the levers and coacting crushing heads are separated, and the machine can be economically manufactured, as its weight is greatly reduced without diminishing its capacity. Any number of levers may be arranged within a single casing, partitions being introduced between the different crushing devices and two double sets of crushing devices arranged in juxtaposition to form a double machine in which each oscillatory lever carries two face plates 13, one on each side, and is arranged between and opposite the face plates 15 attached to the machine casing.

The faces of the face plates 13 and 15 are preferably corrugated, as shown, and the plates are preferably of the shape shown in the drawings; but plates of other shape may be used if desired.

It will be observed that each set or pair of crushing devices leads directly to one of a series of inclined chutes having their lower ends terminating outside the casing on opposite sides of the machine, thereby providing a double delivery of the crushed material.

The casing 7 is constructed to inclose the oscillatory lever 8 and its operating mechanism which is located within the lower part of said casing as shown in Fig. 1. The upper portion of the casing 7 is provided with surrounding ledges or flanges 29 that are provided with recesses 30, Fig.2, or otherwise adapted to receive and support the timbers for forming a platform to be built around and upon a level with the upper part of the casing, thereby permitting the unloading of material immediately into the crusher.

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

1. The combination of a casing having a vertical partition or wall, an oscillatory lever pivotally suspended at each side of the partition or wall, the face plates 13 and 15 attached respectively to both sides of each lever and to the opposite inner sides of the casing, and a single shaft connected with and operating the levers, substantially as described.

2. The combination of a casing 7 having a central vertical partition or wall 7, an oscillatory lever 8 pivotally suspended at each side of the said partition or wall, the face plates 13 secured to opposite sides of each lever, the face plates 15 secured to the casing at opposite sides of the said partition, a single shaft 26 provided with eccentrics 27, and connecting rods 28 between the eccentrics and the levers, whereby the levers are oscillated by a single shaft, substantially as described.

3. The combination with a casing, and crushing mechanism, of a face plate 15, having a lug 19, said lug having an inclined upper surface, a recess 21 in said casing, bolt 23, having a nut 22, said nut having an inclined under surface adapted to rest upon the upper surface of said lug, and means for securing said plate upon the casing, substantially as described.

4. The combination with a casing, and crushing mechanism, of a plate 15, having a lug 19 and a groove 16, a bolt 17 projecting through said casin g into said groove 16, said bolt having a head adapted to fit into said groove 16, bolt 23, nut 22 carried thereby, and a recess 21 in said casing adapted to receive said nut 22, the said lug 19 and the nut 22 being provided with inclined surfaces in contact with each other, substantially as and for the purpose specified.
