CRUSHER.

SPECIFICATION forming part of Letters Patent N o. 668,651, dated February 26, 1901.

Application filed. May 2, 1900. Serial No. 15,190. (No model.)

To all whom it may concern:

Be it. known that I, WILLIAM H. LINeo, a citizen of the United States, residing at Hollyville, county of Sussex, and State of Delaware, have invented a certain new and useful Improvement in Crushers, of Which the following is a specification.

My invention relates to a new and useful improvement in Crushers for pulverizing ore or like material or grinding corn and the like, and has for one object to providean exceedingly simple and effective device of this description capable of being operated by hand by a simple reciprocating movement.

A further object of my invention is to provide means for adjusting the movable member relative to the stationary member, so as to determine the degree to which the material is crushed or ground.

With these ends in View this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled inthe art to which this invention appertains may under stand how to make and use the same, the

construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a central section of myimproved Crusher, showing it secured to a beam or other suitable surface; Fig. 2, a plan view of the device; Fig. 3, a section at the line 0c a; of Fig. l; Fig. 4, a bottom plan of the crushingjaw; Fig. 5, a detail section of one of the eccentric bushingsand the means for holding itin adjustment, and Fig. 6 an elevation of one of these bushings.

In carrying out my invention as here embodied, A represents the body of the device, which is made in the shape of a trough, having formed in the bottom thereof rows of teeth B, which are concaved, as indicated at C, each row of teeth being notched, as shown at D, these notches varying, as shown at E. In this boX is fitted the crushing-jaw F, which is pivoted, as will be hereinafter set forth, so as to be oscillated to and fro therein. This jaw is curved to correspond with the curvature in the bottom of the body and has formed thereon the rows of teeth G, which are also notched, as indicated at H and I, to correspond with the notches formed in the rows of teeth B. The rows of teeth upon the jaw match into the spaces between the rows of teeth in the body, so that when they are oscillated the notches in each set of teeth will bring about a crushing and grinding action, as well a grad ual feeding downward of the material, until it is finally ejected from the lower end of the device in the state of disintegration desired. The upper portion of the jaw is formed upon a straight line and matches the straight portion of the bottom of the body, as clearly shown in Fig. 1, and

thereby acts in conjunction with the body as a hopper or receptacle, as will be readily understood. The shape of the teeth is clearly shown in Fig. 4, and they readily act to draw the material in during the oscillations of the jaws,first roughlycrushing the same,and then gradually crushing and grinding it iiner and finer until the desired limit is reached.

The jaw is pivoted Within the body in the following manner: J is a rod or shaft which is passed through the lugs K, formed upon the jaw and into the bushing L, set in the posts M, projecting upward from the body. The bearings in these bushings are formed eccentric relative to the peripheries thereof, so that by revolving the bushings the shaft will be raised or lowered, as the case may be. The periphery of each of these bushings is polygonal, as indicated at N, and is itted in a corresponding hole formed in the standards M, which will lock the bushings in any adjustment-that is to say, when the bushings are turned upon their axis for the raising or lowering of the shaft and again set within the polygonal-shaped holes they will be prevented from turning upon their axis until withdrawn therefrom, and in order that they mayA not be accidentally displaced a strap O is provided for each bushing and is adapted to fit over the edges of the standards, as indicated at P. When these straps are invplace, the bushings cannot be withdrawn from their bearings, but when it is desired to adjust the bushings the straps are removed,`.the bush- IOO ings withdrawn from their bearings, turned to the proper degree, and reinserted in the holes and the straps replaced, thus providinga positive adjustment for the shatt, which cannot be displaced.

A handle Q is provided for the oscillation of the jaw and may be made of wood or any other suitable material and is fitted between the ears R and the posts K and held in place by a pin S being passed through said ears and the handle, while the shaft .I serves to hold the lower end of the handle in place. This permits the handle to be moved when occasion requires, thus facilitating the shipping or storing of the device.

Suitable screws T are utilized for securing the crusher to a beam or other suitable surface at the proper angle to perform the Work, this angle being illustrated in Fig. l. In practice the material is placed in the upper end of the crusher and the handle Q oscillated to and fro, which will cause the curved portion of the jaw to ride in the concentric concaved portion of the body, while the straight portion of said jaw will be caused to move back and forth relative to the body, thus roughly crushing the material, after which it will be gradually fed downward and reduced, as before set forth.

Atapering plate Q is slidable on the lever Q and is slotted to receive the studs q, by which the movement of said plate is limited. The plate is provided to engage the pivot of the jaw to prevent wear on the lever when wedged thercagainst and swung.

One of the principal advantages of my improvement is its exceeding simplicity and the fact that there is but one moving part therein which may be easily removed for repairor substitution, if occasion requires, and as the device may be almost wholly made from castings with little or no finish the cost of manufacture is relatively small.

Having thus fully described my invention, what I claim as new and useful is- 1. In a device of the character described, a body having teeth, a jaw working in conjunction with the body and means for pivoting the jaw, an operating-lever pivoted to the jaw and a plate slidable on the lever and engaging the pivot of the jaw, substantially as described.

2. In a device of the character described, a trough-shaped body, rows of teeth formed on the bottom thereof, said teeth being concaved and notched, a jaw curved to the contour of the bottom of the trough, rows of notched teeth formed on the jaw matching into the space between the rows of teeth in the body, the upper end of the jaw being straight to match a straight portion of the trough, lugs formed on the jaw, bushings set in posts of the body, eccentric bearings for the bushings, the periphery .of each bushing being polygonal and fitting in corresponding holes in the standards, a strip for each bushing fitting over the edges of the standards, an operating-lever pivoted to the jaw. a tapering plate slidable on the jaw and wedged under the pivot of thejaw substantially as described.

3. In combination, a trough, a jaw acting in conjunction therewith and means for pivoting the jaw comprising lugs formed on the jaw, bushings set in posts ofthe body, eccentric bearings for the bushings, the periphery of each bushing being polygonal and tilting the corresponding holes in the standards, and a strip for each bushing fitting over the edges of the standard substantially as described.

In testimony whereof I have hereunto afiXed my signature in the presence ot' two subscribing witnesses.
