"UNITED STATES PATEN orrio EDWIN S. PHILIPS, 0F KENNE'IT SQUARE, PENNSYLVANIA, ASSIGNOR TO THE AMERI- CAN ROAD MACHINE COMPANY, OF KENNETT SQUARE, PENNSYLVANIA, A GOR- PORATION OF PENNSYLVANIA.
ROCK-CRUSHER.
T 0 all whom it may concern:
Be it known that I, EDWIN S. PHILIPS, a citizen of the United States, residing at Kennett Square, county of Chester, and State of Pennsylvania, have invented a new and useful Improvement in Rock-Crushers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
The object of my invention is to provide a rock-crusher adapted to be converted from a crusher of large capacity to one of relatively small capacity, and vice versa, in accordance with the amount of work at any given time to be done. Heretofore it has been customary for the user to have on hand a plurality of separate crushers, one only being used when a relatively small amount of stone was required to be crushed, while the remaining crusher or crushers was brought into use when the amount of stone to be crushed increased beyond the capacity of a single crusher.
My invention consists in a duplex crusher provided with a single fixed jaw and a plurality of movable jaws, each having separate and independent actuating mechanism, arranged on opposite sides of the fixed jaw, as hereinafter claimed.
My invention also consists in certain novel features of construction applied to the fixed jaw and hopper and certain novel features of arrangement of the same with respect to the moving parts, as hereinafter claimed.
In the drawings Figure 1 is a plan view of the crusher with a hopper removed. Fig. 2 is a section on the line 2-2 of Fig. 1.
Certain details of construction are omitted from the drawings and description, as they are known in the art and form no part of my invention.
10, 10 are the side plates of the machine between which the operative parts of the crusher are secured.
11 is the fixed jaw member carrying on opposite sides dies 12, 12.
13, 13, are the movable jaws arranged 011 opposite sides of the fixed jaw and carrying dies 14, 14 arranged opposite, and cooperating with, the dies 12, 12, respectively of the fixed jaw. The movable jaws are pendulous from the fixed shafts 15, 15, respec- Specification of Letters Patent.

tively, extending between, and secured to, the side plates from the outside.
At each end of the crusher is a shaft carrying the cam 16. This cam-shaft ro tates in bearings secured to the outside of the side-plates and carries the fiy-wheels 17, which serve as belt-wheels for driving the corresponding end of the crusher and also as traveling wheels in transporting the crusher from place to place. Each cam 16 actuates a tumbler roller 18, whose axle revolves in bearings in side-flanges 19 on the upper and outer end of a tumbler-lever 20.
Each tumbler-lever 20 at its lower and inner end surrounds and is secured to a shaft 21 by means of a set screw 22 extending through the tumbler-lever and engaging a flattened face of the shaft. The shaft is flattened on opposite sides so that it may be reversed to compensate for wear. The shaft 21 oscillates in bearings secured to the outside of the side-plates. The upper and outer end of each tumbler-lever 20 is held against its actuating cam 16 by means of a compression spring 23 confined between this end of the tumbler-lever and a casting 24: secured between the side-plates.
The opposing faces of the moving aws 13 and their corresponding tumbler-levers 20 are provided with clove-tail recesses within which are fitted the toggle-seats 25. The toggles 26 are seated at their opposite ends in the toggle-seats 25.
At each end of the crusher, adjacent to the inner walls of the side-plates, are plates 27 supported on bolts 270 passing through and extending between the side-plates. Bolted to each plate 27 is the depending T- bar 28. A rod 29 extends from each side of the lower free end of the moving jaw 13 and extends through the corresponding T- bar 28. A spring 30 is confined between the T-bar and a nut 31 threaded on the outer end of the rod. The function of these springs and rods is to hold each moving aw in operative relation with its corresponding tumbler-lever. I
Each die 1ft is set into a recess in the face of the moving jaw 13. A wedge-shaped orifice extends through the jaw on each side of its center, the lower part of the orifice opening into the die-recess and its upper part alining with a groove formed in the overhanging part of the jaw above the die're provided a hopper as whose inwardly in cess. this groove and recess and also into a groove in the upper end of the die l t. The rear end of the key is circular in shape and is threaded to receive anut 33 and washer 34E abutting against the back of the die and by means of which the key 32 may be drawn inwardly to securely confine the die in its recess.
35, 35, are reversible and interchangeable cheek-plates or liners secured to the side plates opposite the crushing faces of the dies. These plates protect the side-plates from wear due to the crushing of stone.
The fixed jaw 11 is provided at each side with vertically extending tongues 38 extending into vertical grooves 87 formed on the inner walls of the side-plates. The jaw 11 is securely held between the side plates by means of bolts 38 extending from one side plate to the other and entirely through the jaw. The fixed jaw is also provided with pockets in its lower face, in which are the heads of bolts 39. These bolts extend outwardly through the adjacent part of the jaw and through the side-plates and are tightened by means of nuts. The upper face of the jaw is provided with pockets 41 and bolts 42 extend from these pockets outwardly through the jaw and the side-plates and are tightened by means of nuts $3.
The dies 12 are held in position by means similar to the means for holding in place the dies lat of the moving jaws 13. edgeshaped orifices extend outwardly from the pockets 41 through the aw, the upper parts of the orifices alining with grooves formed in the part of the jaw overhanging the die. Into each orifice and its corresponding groove extends a wedge-shaped key 4.4., which also extends into a groove in the upper end of the die. By means of the nut 15 on the inner end of the key, the same is drawn inwardly, causing the upper face of the key to press against the aw and the inclined lower end to press against the die, thereby securely holding the die in its recess.
superposed on the fixed jaw is a cap 46. This cap, besides entirely overlying the jaw, extends down to the die-recesses. Above the key-ways, the cap is cut away on the inside to permit the jaw to be enlarged at these points for the purpose of lengthening the bearing surface of the keys 41 against the jaw. The lower edges of the cap are also grooved across at these points, these grooves alining with the grooves in the jaw to permit the keys to be inserted in their ways.
The cap is held on the fixed jaw by means of bolts 4L7. The heads of the bolts are seated in a recess formed by cutting away the cap and jaw and the shank of the bolt extends through a groove formed in the under face of the cap.
To feed the material to the jaws there is A wedge-shaped key 82 extends into clined end walls extend over, and down in front of, the pivoted upper ends of the moving jaws respectively, and whose side walls incline inwardly toward the side-plates and thence extend vertically downwardly along the inner walls of the side plates and terminate at the upper ends of the cheek-plates The upper face of the cap slopes downwardly from its central part toward the dies 12, 12, respectively, thereby, in conjunction with the hopper, guiding the material bet-ween both sets of crushing dies.
Heretofore, when two single crushers have been used together, they have often been arranged end to end so as to enable them to be fed together from dump carts or dump cars. This arrangement has never worked satisfactorily, owing to the fact that there are two separate and distinct and relatively small openings, 2'. 6., the spaces between the fixed jaws and their corresponding movable jaws, to receive the stone, and the stone con sequently often bridges or arches over one or both openings, which clogs the opening and renders the crusher inoperative. In my invention, however, the two receiving openings are so close together as to form virtually a single wide opening, so that when the material is dumped into the single hopper spanning the space between the movable jaws, there is much less likelihood of the material becoming clogged in the opening. The liability to clogging is also lessened by constructing the cap forming the upper part of the fixed jaw so that its opposite sides slope downwardly toward the two movable jaws.
Either end of the crusher can be thrown out of operation at will, and the end in operation will crush the same amount of mate rial as a single crusher of normal capacity, but it is obvious that its cost of construction is substantially less than the cost of construction of two single crushers, and besides is more economically transported from place to place. hen the crusher as a whole is operated, it will have the same capacity as two single crushers of normal capacity or the same capacity as an ordinary crusher having a double width of aws. When both ends of the crusher are in use, the advantage over an ordinary crusher of the same capacity is that the strain upon the fixed aw in either direction is only half the strain upon the fixed jaw of the ordinary crusher and what strain there is in one direction is counterbalanced by an equal strain in the opposite direction.
\Vhile the movable aws are independently operated by their actuating mechanism, it must not be understood that the latter need be driven from a separate source of power. On the contrary, the more convenient method of driving would be to drive both crushers from the same engine by belting the engine pulley to the fiy-wheels of one crusher and then belting the engine pulley to the flywheels of the other crusher by means of belts overlying the firstnamed belts; it being understood there will thus be two driving belts for each crusher or four belts in all.
Having now fully described my invention, what I claim and desire to protect by Letters Patent is 1. In a rock-crusher, the combination with side plates, of shafts between the side plates, movable jaws pendulous from the shafts, a fixed jaw between the movable jaws, a cap surmounting the fixed jaw and havin sides sloping toward the movable jaws, said cap being located below the level of the tops of the movable jaws, and a hopper above the cap having side walls extending in front of the pendulous upper ends of the movable jaws and forming with said cap a plurality of passages for the delivery of material to be crushed on opposite sides of the fixed jaw.
2. Ina rock crusher, the combination with a fixed crushing jaw having a-die recess in the side thereof, and a key-way through its side wall at the upper end of said recess, of a cap overlying said jaw and extending downward to said die recess, said cap having a cut-away portion above said key-way and into which the upper end of the fixed jaw extends, a die seated in said recess, and a key extending through said key-way and abutting along its upper side against said jaw and the part of the cap not cut-away.
3. In a rock-crusher, the combination of movable aws, dies carried thereby on their opposing faces, a fixed jaw between said movable jaws having die-recesses in opposite sides thereof, a cap overlying the fixed jaw and extending downwardly to said dierecesses, a die seated in each recess, and grooved across its upper edge, there being an orifice through said jaw and grooves in the part of the jaw overhanging the dierecess and in the contiguous lower end of said cap, said grooves in the cap and jaw alining with the upper part of said orifice, and a wedge-shaped key extending into said grooves and orifice, and means to draw said key inwardly, thereby confining the same between the jaw and die and holding the die in its recess.
4. In a rock-crusher, the combination with a fixed jaw having die-recesses and dies seated in said recesses, of movable jaws located on opposite sides thereof, there being completely inclosed pockets in the upper part of the fixed jaw and orifices through the fixed jaw between said pockets and the die-recesses respectively, and keys in said orifices confined between the walls thereof and the dies.
5. In a rock-crusher, the combination with a fixed jaw having die-recesses and dies seated in said recesses, and grooved across their upper edges, of movable jaws located on opposite sides thereof, there being pockets in the upper part of the fixed jaw and orifices through the fixed jaw between said pockets and the die-recesses respectively, grooves in the parts of the fixed jaws overhanging said die-recesses, said grooves alining with the upper parts of said recesses, tapered keys in the grooves of the aw and dies and extending through said recesses, and means in said pockets to draw the keys inwardly, thereby pressing said dies downwardly against the bottom of the die-recesses.
6. In a rock-crusher, the combination with side plates and a fixed jaw between the side plates, of movable jaws between the side plates on opposite sides of the fixed jaw, there being pockets in the fixed jaw, on opposite sides of a line extending centrally and longitudinally of the crusher, and bolts, each extending from one of said pockets outwardly through the body of the fixed jaw and the contiguous side plate.
7. In a rock-crusher, the combination with side plates and a fixed jaw between the side plates, of movable jaws, having die recesses, between the side plates on opposite sides of the fixed jaw, there being die recesses on opposite sides of the fixed jaw and pockets in the top of the fixed jaw on opposite sides of a line extending centrally and longitudinally of the crusher, dies one in each die recess, a cap overlying the fixed aw, whereby the pockets are completely inclosed, bolts, each extending from one of the pockets outwardly through the body of the fixed jaw and the contiguous side plate, and keys, each extending from one of said pockets outwardly through the body of the fixed jaw and engaging one of the dies of the fixed aw.
In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 15th day of May, 1908.
