EDGAR H. BOOTH, OF SAN FRANCISCO, CALIFORNIA.
STONE OR ORE CRUSHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 473,725, dated April 26, 1892.
Application filed June 20, 1891.
To coZZ whom it may concern:
Be it known that I, EDGAR H. BOOTH, a citizen of the United States, residing in the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Stone or Ore Crushing Machinery; and I hereby declare the following specification and drawings accompanying the same to be a full, clear, and exact description of my invention.
My invention relates to machines for crushing ore, stone, or any kind of mineral substances, reducing them to various degrees of fineness, as their nature and uses may require; and it consists in the construction, arrangement, and combination of the several parts, substantially as will be hereinafter described and claimed.
The objectof my invention is to provide a crushingmachine for stone or ore with a wider range of capacity as to the size of material fed in and amount crushed with rela tion to the power employed and the fineness of the product when crushed, also by pivoting the upper or first jaw above the arc in which it swings produce a movement best suited for preliminarycrushing, and by pivoting the lower jaw below the arc in which it swings adapting that one to finishing or fine crushing.
Another object of my invention is to attain nearly-continuous action of the machine by reason of the alternating motion of the two jaws, and thus avoid in a great degree the strains such machines are subjected to when their work is done during one-half only of each revolution of the driving-shaft, also the unequal wear on the principal working parts caused thereby, and thus the strains in my improved machines for a given work being approximately only one-half as much at any instant of time as when such machines are single-acting or have only one reciprocating jaw.
In the drawings, Figure 1 is a side elevation of one of my improved stone and ore crushing machines. Fig. 2 is a plan view of the same machine with a few of the details omitted; and Fig. 3 is an enlarged longitudinal vertical section through the same machine,
showing the various operating parts in their relative positions and connections.
Serial No. 396,925. (No model.)
Like letters of reference on the different figures indicate corresponding parts of the machine.
The main frame of the machine is made with the two side members A A and the two end members B and O, the whole being joined by the heavy rods or bolts D and D provided at the ends with screw-nuts, as shown. The upper or first crushing-jaw E is pivoted or fulcrumed above its crushing-face on the shaft or pin G in the upperpart of the frame and the lower or finishing crushing-jaw F is pivoted or fulcrumed below its crushing-face on the shaft or pin Hin the lower part of the frame. The shaft I, carrying the eccentric T, is driven by the pulley J and is provided, also, with a fly-wheel K, or two fly-wheelsone at each sidecan be employed. The present machine is shown with one, because the equalizing effect of such wheels required is less than is the case with machines having one movable jaw. The stationary jaw L is shown in an approximately vertical position, with the movable jaws E and F standing at an inclination thereto. The stationary die L and front member B of the main frame, constituting the fixed jaw of the machine, are made long enough to accommodate the action of both jaws E and F, the crushing-faces being, as usual, faced, as shown, with hard material to resist abrasive wear of the faces.
M is the driving link or pitman, receiving its motion by means of the eccentric T, fixed on the shaft I, revolving within its head M and operating the upper jaw E by means of the toggles or thrust-plates N and 0, taking their abutment on the thrust-wedge P and against a die Q in the back of the jaw E, as shown in Fig. 3. The link R is an extension of the link M and receives its motion from it through pin S which is transmitted through pin S to lever F cast on or attached to back of jaw F. It will be seen that the downward movement of the link M produces a forward or crushing movement of the jaw E, and the upward movement of the same, by reason of the link R, produces a forward or crushing movement of the jaw F, these movements being reciprocal, one movable jaw receding from stationary jaw L while the other is making a forward crushing movement, and all working strains in the machine of whatever kind are thus divided and more equally distributed on the eccentric-shaft I, falling on each half-revolution thereof, and as nearly continuous as the action of the reciprocating jaws E and F will permit. The position of the upper jaw E is governed by the adj ustable wedge U, acting against the thrustwedge P, being moved up or down by the screw-bolt V, as the nature of the work may require or to compensate for wear of the crushing-faces. The jaw F can also beadjusted by means of the bearings W, one hearing being in each side of the main frame A, and can be moved forward or back in the slot X by changing the filling in plates Y to the back or front of the bearings NV, as the wear on the face of the jaw F or the fineness of the material to be crushed may demand. The bearings W are made in two parts, the follower or cap-piece c, as well as the bearing W itself, being held firmly. against the abutment at c by means of the spring e, the plate m, and set-screw n, as shown in Fig. 3, the jaw F being held on the shaft or pin H by set-screws s, so the latter will turn in the bearings W, the object being to, take up all lost motion and prevent noise or pounding in the bearings W due to wear, which can be done by adjusting the tension of the spring a with the set-screw n, thus forcing the cap-piece 0 against the shaft II and holding it firmlyin bearingW. To the rear of the upper jaw E, I attach a rod Z, passing through aspiral spring a, the latter causing an elastic tension against the toggles N and O and pulling back the jaw E after each forward movement in the usual manner. To the rear end of the lever or jaw W, I attach a similar rod 0, also strained by a spring 1' and having the double function of preventing lost motion in the bearings of the pins S and S of the link R and of pulling back the jaw F after each forward movement.
Having thus explained the nature and objects of my invention and the manner of applying and constructing the same, what I claim as new, and desire to secure by Letters Patent, is
1. In a crushing-machine, the combination of the stationary jaw, the upper movable jaw, which is fulcrumed above its crushing-face, the lower movable jaw, which is fulcrumed below its crushing-face, the actuating-shaft eccentric thereon, apitman which receives its motion from said eccentr1c,a connecting-toggle between the pitman and the upper jaw, a
link pivoted to the lower end of the pitman,
above its crushing-face, in combination with the extension-link R, transmitting its motion through lever F to the lower jaw F, pivoted below its crushing-face, so as to produce alternate and approximately continuous crushing movement of jawsE and F and divide the strains upon eccentric-shaft, together with the abutment or end member 0, substantially in the manner and for the purposes specified.
3. In a crushing-machine, the combination, with the stationary jaw, of a jaw having a rearward lever or extension, a spring-rod arranged to act as a tension device on the rear end of the said lever, the actuating-shaft, an eccentric thereon, a pitman operated by said eccentric, and a link pivoted to said pitman and to thelever on the jaw, substantially as described.

said jaw F having a rearward extension F the shaft I, eccentric T thereon, pitman M,
driven by said eccentric, toggles N and O, the adjustable wedge U, acting against the thrustwedge P, which is adjusted up or down by the screw-bolt V, andthe link R, pivoted to the lower end of the pitman M and also to the extension F substantially as described.
7. In a stone and ore crushing machine, the combination of the main frame having the. side members A and the end members B and O, the stationary jaw L, the movable jaws E and F, located opposite thereto, the driveshaft with an eccentric thereon, and the pitman operated by said eccentric, the toggles N and 0, said toggle N being located between the pitman and the jawE and said toggle 0 being located between the pitman and the wedge P, adjustable wedge U, the screw-bolt V, upon I Io In testimony whereof I have hereunto affixed my signature in the presence of two Witnesses.
