MECHANICAL MOVEMENT FOR ORE-CRUSHINQ MACHIINEZS.
SPECIFICATION forming part of Letters Patent No. 257,852, dated May 16, 1882.
' Application filed July 21, 1881. (No model.)
To all whom may concern: I Beit knownthat I, JACOB DAVID, a citizen of the United States, residing at Brooklyn, in thecountyof Kings, State of New York, have invented a new and useful Improvement in' Mechanical-Movements for Ore-Crushing Mafollowing is a specificachines, of which the tion.
My invention relates to mechanism for converting a rotary motion into a reciprocating motion by the use of cranks and toggle-levers,
as hereinafter fully set forth.
Figure 1 is aview in perspective of the work ing parts of the machine with the frame orcasmg of one side removed. Fig. 2 is a cross-sec- -tion ofthe toggle-lever Q or E, showing part.

Fig. 4 is a side view of the opposite or reversed side'ot' the machine shown in Fig. 3. Fig. 5 is a longitudinal sectional view through the center. Fig. 6 is a top plan view. Fig. 7 is a horizontal section on a, line drawn through the pivot I to the pivot G5 Fig. 8 isa section of the casing or flitlilG Of the, machine, showing the slot in the casi n g through which the pivot I connects the jaw B andthe.
levers K.
Similar letters refer to similar parts throughout the several views. X
The part marked A is a part of the framework of the machine, and at the same time forms an immovable face or jaw, against which the material is crushed finer after being passed between the other jaws.
The part'marked B is a movable jaw, bun g 1 by suitable pivots, which pivots or journals enter suitable journal boxes or holes made in the frame-work of the machine. The jaw B obtains a reciprocating motion from the togglelevers K L and the connecting-rods M, which rods M connect to the cranks 0 on the shaft "0.
Both sides of the machine have toggle-levers KL and connecting-rods M, as shown in the several views. i r
The toggle-lever L is connected at one end to a fixed support by a pivot at G and the otherend is connected by a pivot to one end of the toggle-lever K and to one end of the connecting-rod M. The other end of'the toggle-lever K is connected to the movable jaw B v by a pivot at I.
The pivots (marked 1) on each sideot' thejaw B pass through the casing or frame ot' the crusher and connect to the toggle-levers K on the outside of the machine,said pivots (marked 1) moving in suitable slots on each side of the machine, said openings or slots being of such a shape-as to allow the movable jaw 13 to move forward and backward.
The cranks O are fixed on the revolving shaft 0, and the connecting-rods M engage the cranks O at one end and at the other end engage the toggle-levers K L by pivots at N. a
The cranks, (marked 0,) the toggle-levers K and L, with the connecting-rods M, are all on the outside of the casing of the crusher, one set of levers and one crank 0 being on each side of the machine, as shown at Figs. 1,3, and 4; i
The part marked (lie also a movable jaw, hung on suitable pivots orjournalsin suitable journal-boxes or holes in the frame at b. The journal-boxes are attached to the frame in a suitable'manner. The jaw 0 receives a reciprocating motion from the toggle-levers E Q, the pitman D, and the crank 1. One end of the toggle-lever E is set in a notch in an immovable support at H. The other end of the toggle-lever .E is set in a notch in the end of the pitman D. The pitmauD is connected to the crank P at f. One end of the toggle-lever Q is connected to the pitman D at a point ercactly opposite the notch that receives the'toggle-lever E. The other end of the toggle-lever Q is connected by a notch on the back-and lower part of the movablejaw (l.
The toggle-levers E and Q are held in position'in the notch in the immovable support H, in the notches on the pitman D, andinthe notch on the movable jaw (J by the steel rods or bars marked F F, which bars or springs'are fastened in a suitable manner to the immovable support H, passing from thence through a groove in the toggle-levers E Q, and=terminatin g at a suitable fasteuin g on the movable jaw O.
\ If the bars or springs F F are fastened iu a suitable mannercne end to the immovable support and the other end to the movable'support--when the pitman D israised to its highest point or depressed to its lowest point by the revolution of the crank P thejaw or movable support 0 will be brought back and away from thejaw B. By each half-turn of the r0- taryshaft e the toggle-levers E and Q straighten, or become parallel, and press against the immovable support H and push the movable support or jaw 0 forward and against the other movable support or jaw B.
The crank P, pitman D, and toggle-levers Q E are all inside the casingof the machine. The interior parts are shown bythe dotted lines in the several views.
When the cranksO and Pare placed at right angles to each other, as shown at Figs. 1, 3, 4, 5, and the crank P is at its highest point, it will raise the pitinan D, which in its turn will raise the toggle-levers E and Q at the ends co'nnectedto the pitman D. By so doing the toggle-levers are shortened and the jaw G drawn back. At the same time, the crank P being at a right angle and horizontal to the cranks 0, j
the outside toggle-levers, L K, will then be in a straight line, or at their longest, which will cause the jaw B to be pushed away from the other movable jaw, O, and against the immovable jaw A. By one-quarter of a revolution of the shaft 0 the crank P is horizontal and the cranks O perpendicular, and exactly the reverse of the foregoing operation takes place,
as by this latter motion the movable jaws B and O approach each other. and the jaw B recedes, and is drawn from the immovable jaw A. By turning the shaft 0 one'quarter of a revolution farther, making a total of one-half of a revolution, the same result follows in the operation of the jaws as described in the first instance, while by moving one-quarter of one revolution more, making three-quarters of one revolution of the shaft 0, the same result follows in the operation of thejaws as described above in the second instance.
The parts F F are two flat bars or springs, made of steel, that are placed 'in a groove formed one on each side of the toggle-levers Q and E. The springs or bars F F are fastened at one end to the immovable support H and the other end to the movable support or jaw C. By having the bars or springs attached to the movable support Oand the immovable support H and passed through the toggle-levers in a groove, as shown, the toggle levers will not slip out of the notches when the machine is in motion, and when the pitl'man'D is at the highest or the lowest point allowed by the revolution of the cranks and shaft the toggle-levers will be retained in the notches and the movable support or jaw 0 both be brought back and away from the other movable support or jaw, B. Nearly the sameresult can be accomplished by having one spring or bar, 13, passed from end to end through the center of the toggle-levers Q and E and pitman D and fastened to the movable and .immovable supports, as described above.
When the parts are constructed and put tocauses the movablejaws B and (J to approach to and recede from each other at the same time twice to each revolution of the shaft. At the time thejaw B is receding from thejaw U thcjalw B is approaching to and antagonizing with the immovablejaw A.
When'the machine is in motion the material to be crushed is fed between the movablejaws B and G, which are setacertain distance apart, and by their operation reduce the material to a certain size. After the material has passed between thejaws B and O and been crushed to the proper size it is then taken up and passed between thejaws A and B. Thejaws A and B being closer together than the jaws O and B, the material is reduced to a much finer state than by the first operation. After a sufficient part of the material has been reduced by passing the same between the jaws O and B it is then fed between thejaws A and B. At the same time more of the material is passed between the jaws B and 0, thus making the two operations simultaneous, crushing the coarse material between one set ofjaws and the finer material between the other set of jaws during one revolution of the shaft, thus crush-- ing the coarse material by one movement, and crushing thefinermaterial by the reversemovement of the parts. By placing the two cranks O on the outer ends of the shaft 0, with the crank-levers M and M and toggle-levers KK and L L, one set of each on each side of the machine, outside the frame, the jaw B will be pressed against the immovablejawA in a much firmer and more solid manner than where only one set of cranks and toggle-levers is used and affixed to the center of the jaw, as shown and described in Letters Patent of the United States, No. 222,872, granted to me on the 23d day-of December, 1879.
What I claim is- 1. In ore-crushing machines, a mechanical movement consisting of the movable support 0, the toggle-levers Q E, the pitman D, provided with n0tches,the crank P, and shaft 0, in combination with the mechanical movement consistingof the movable support B, the toggle-levers K L, the immovable support H, crank-levers M, and cranks O, for the purpose as shown and described.
