ATENT JOSEPH ASBURY JOHNSON, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE'HALF TO GEORGE H. STEWART, OF LOS ANGELES, CALIFORNIA.

ORE-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 727,958, dated May 12, 1903. Application filed July 26, 1901. Serial No. 69,821. (No model.)

T0 at whom it may concern.-

Be it known that'I, JOSEPH ASBURY J OHN- SON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Ore-Crusher, of which the following is a specification.

This invention relates to apparatus for reducing or pulverizing material, and particularly for crushing oreor quartz to a find state or condition; and some of theolojects of this invention are to provide an apparatus of this general character which will be simple and cheap in construction and at the same time positive and effective in operation.

Another object of the invention is to provide an apparatus embodying direct crushing action combined with a rubbing action, so as to reduce the material operated upon to a finely-divided state.

A further object of the invention is to provide an apparatus constructed to receive and pass portions of material foreign to that operated upon and which is practically uncrushable and to do so without injury'to the apparatus.

With these and other. objects in view the invention consists, essentially, in the ,construction, combination, and arrangement of parts substantially as more fully described in the following specification and illustrated in the accompanying drawings, forming part.

of this application, in which Figure 1 is a top plan View of an apparatusembodying the improvements; and Fig. 2 is a side elevational view, partly in section, showing one side of the apparatus removed.

Similar characters of reference designate corresponding parts throughout the several ceive the material to be operated upon and with a stationary or movable crusher-bed 3, preferably removably connected with the end 4 of the frame, desirably by means of a dovetailed tongue-and-groove connection 5, substantially as shown in Fig. 2 of the drawings, whereby the crusher-bed may be removed when injured or worn and a new one introduced.

Mounted in bearings 6 in the frame is a shaft 7, carrying balance- wheels 8 and 9 and a pulley or band wheel 10, adapted to receive a belt or band actuated by any suitable driving mechanism or motor, (not shown,) as will be readily understood. The intermediate portion of said shaft is preferably constructed with an eccentric 11, double-cam, or other construction to impart motion, whereon is mounted one end of an arm 12, preferably provided with a dovetailed slotl3 to receive a dovetailed tongue or, projection 14 upon a movablejaw 15, substantially as shown in Fig. 2 of the drawings, whereby the latter maybe renewed or replaced when injured or worn. By means of this construction the movable jaw 15 is caused to travel up and down against the crusher-bed by the revolution of theshaft'V, through the action of the eccentric 11 thereon, thereby causing a rubbing action of the material feeding down between the crusher bed 3 and the movable jaw 15 and tending to finally. reduce the material operated upon. Upon the other side of the arm 12 is preferably secured one or more hooks or other devices,16, constructed to receive, preferably, a spring or like device 17', which may be connected at the opposite end thereof with an adjusting-rod or other device 18, preferably adjustably mounted in the end 19 of the frame by means of jam-nuts 20, substantially as illustrated in Fig. 2 of the drawlugs.

It will be understood that any number of springs 17. may be employed to normallyretract the arm 12 or that other means maybe employed for this purpose if found desirable in practice.

The frame of the apparatus may be provided with parallel guideways'21 and 22, 0on structed to movably receive a follower-block 23, constructed to receive, preferably, one end of a toggle or other device 24, the opposite end whereof may engage the free end of the arm 12, substantially as shown in Fig. 2, and, if desired, the arm may be cut away to receive a recess bearing block 25, constructed to receive the spherical or rounded extremity of the toggle, and the follower 23 may be likewise provided with a recess bearing-block 26 to movably receive the opposite end of said toggle, essentially as illustrated.

If desired, in practice a fiat bearing-plate may be employed instead of the toggle 24. and may be provided with rounded ends to work in concaves in the arm 12 and the followerblock 23, or a plurality of toggles may be employed, if preferred.

Mounted in the end 19 of the frame are rods and bolts 27 27, preferably provided with jamnuts 28 28. To regulate the distance,the same may pass beyond the end 19, and said end may be provided with an annular flange 29 to receive one end of a spiral spring or other device 30, the opposite end whereof engages a thrust collar 31, preferably interiorly screw-threaded to engage the screw threads on said rod or bolts 27 27 and to be rotated thereon by means of tools inserted in the openings or recesses 32 thereof to regulate the tension of said spring, and the free extremity of said rods or bolts preferably engages recesses 33 33 in the follower-block 23, substantially as illustrated in Fig. 2 of the drawings. It will be understood that any number of these spring-actuated plunger-rods may be employed and that other devices capable of the same function maybe used in lieu thereof if found preferable.

From the foregoing construction it will be understood that when pieces of practically uncrushable material come between the crusher-bed 3 and the movable jaw 15 the latter will yield and allow the material to pass between the crusher-bed and the movable jaw.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In ore-crushing machines, a frame the end thereof provided with a dovetailed groove, a crusher-bed having a dovetailed tongue adapted to be removably secured to the end of the frame, a drive-shaft mounted in the frame, an arm secured to the shaft and having a dovetailed slot therein, a movable jaw removably fastened to the said arm, an adjusting-rod adjustably mounted in the frame, a spring detachably connected to the said rod and to the rear face of the said arm and means adjustably connected to the rear end of the frame for limiting the rear movement of the said arm.

2.-In ore-crushing machines, a frame the front end thereof having a dovetailed groove therein,a crusher-bed provided with astraight face and having a dovetailed tongue adapted to be removably attached to the end of the frame, a drive-shaft, an eccentric fastened to the said shaft, an arm havingadovetailed slot in the front face thereof, a movable jaw detachably secured to the said arm, an adjusting-rod adjustably mounted in the rear end of the frame, a spring detachably connected to the said rod and to the rear face of arm and means elastically and adjustably limiting the rear movement of the said arm and movable jaw carried thereby.

3. In ore-crushing machines, a frame, a crusher-bed secured to the frame, a driveshaft, an arm mounted on the shaft, a movable jaw fastened to the arm, a movable rod adjustably mounted in the rear end of the frame, a spring detachably connected to the said rod and to the rear face of said arm, a toggle, a follower-block and means for adjustin g and elastically supporting said block.

4. In ore-crushing machines, a crusher-bed secured to one end of a frame, a drive-shaft mounted in the frame, an arm fastened to the shaft, a movable jaw secured to the arm, an adjustable rod adj ustably secured in the rear end of the frame, a spring connected to one end of said rod and to the rear face of the said arm, a toggle supported at one end by the arm and at the opposite end by the follower-block, the follower-block, a movable rod engaging the follower-block and aspring thereon to force the rod against the block.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH ASBURY JOHNSON.
