ORE-'CRUSHEFL SPECIFICATION forming part of Letters Patent No. 464,083, dated December 1,1891.

Application filed May 4, 1890. Serial No. 342,589. (No model.) y

To all whom/lit mag/concern.-

Be it known that we, GEORGE RAYMONDand States, residing at Chicago, in the county of Cook and State of Illinois, have invented cer' tain new and useful Improvements in Ore- Crushers, of which the following is a specili-` cation.

Our invention relates to` a machine for crushing ores or othenmaterials wherein a crushing-head operates in conjunction with a casing to crush the ore or other Vmaterial between them.

More specifically stated, our invention relates to a crusher wherein an upright shaft carries on one end a crushinghead surrounded by a casing to confine the material, the other end of said shaft being caused to gyrate. The crushing-head is left free, and `the material falls between the head and surrounding cas-` ing and is crushed 'between their opposing surfaces, the materialY itself forming a'ful-Q crum over which the head rocks,` and the ma# terial, when reduced, dropping out at the bottom of the crushing-chamber.

In one form of construction we employ a suitable base, on which are mounted vertically in proper bearings two shafts, on the lower ends of which are driving gears enmeshed with pinions carriedk upon a rotating shaft, and near the middle of said Yupright shafts are provided enlargements to form eccentrics whichoperate within sleeve-bearings on either end of a` driving-beam, and the latter is'pro7 vided between the eccentricswith a suitable bearing to receive the end ofthe crushingshaft, a hollow column extending centrallyA above the base and through which thecrushing-shaft is passed, an annular frame formed integrally with or bolted to the hollow column and having on its interior a lining to form the crushing-surface surrounding the crushing-head carried upon the upper end of the crushing-shaft, and a hopper in which the material is placed and from which it feeds downby gravity into the crushing-chamber. The driving-beam is preferably suspended by means of rods depending from the hollow column, and these rods are made adjustable, so

5o as to raise or lower the crushing`head,where by to regulate the fineness of the material on line 3 3 of Fig. l.

ing-head in the form of the frustum of a globular body where fine crushing is desired; but where only coarse work is to be done the crushing-head may be in theforni of a frustum of a cone and surrounded by a casing whose walls are in the form'of the frustum of two cones joined at their smaller ends. In another form of construction the head is mounted on the lower end of the shaft and its other end is gy'rated. I

In the accompanying drawings, Figure l is an. end elevation of the machine; Fig. 2 is a side elevation. Fig. 3 is a verticalI section Fig. 4 is a plan below the line 4 4 of Fig. 2. Fig. 5 is a Ysectional detail taken on line 5 5 of Fig. 2. Fig. 6 is the same on line 6 6 of the same figure. Fig. 7 is a plan view of the driving-beam. Fig. 8

isa sectional detail showing `the crushing. .head of the machine in modified form. Figs.

9 andlO are respectively side and sectional elevations of a crusher, in which the crushing-shaft is geared at its 4upper end and the head and crushing-chamber are at the lower end of the shaft; and Fig. ll is a cross-section of the upper part of the crusher shown in Figs. 9 and l0 and taken at' a right angle to Fig. 9.

In the drawings,.Figs. 1 to 8, inclusive, A indicates a suitable wooden or iron base, upon which isl mounted a rotatable driving-shaft B, carrying pinions b Y), a pulley B', and a lbalance-wheel. l Mounted upon this frame 4areth'e bearings CC to receive the eccentric- I-I II represent suspend-ing rods or bars whose upper ends are passed through apertured lugs Il and have the securing and adjusting nuts h. These rods pass downwardly through openings in the hollow column, and their lower ends are passed through apertures in the driving-beam I. This beam is particularly shown in Figs. 3 and 7 of the drawings and is a skeleton casting having formed cen- IOO .shown in the preceding figures.

stance are secured with the shaft itself.

brate with the shaft.

trally thereof a box l and at each end thereof bearings to receive the eccentric portions (l of the shaft D. i

J represents the crushing-shaft, whose lower end is seated within the box l and preferably surrounded by a bushing j. The upper end of this crushing-shaft projects above the top of the column F and bears thereon a crushing-head K, which is preferably made separable from the shaft, so that it can be replaced when"worn, and which may have a smooth or corrugated surface, as desired.

L is an annular frame, which may be formed integrally with or bolted to the upper part of the column, and which is provided with the lining M to fornia crushing-surface, and N is a `hopper from which the material is fed.

By referring to Figs. 5 and .dof the drawings, it Will be seen that the annular frame L is con-nected to the central column by means of the ribs Z,which will preferably be thinned yoff on their upper surfaces, as clearly show-n in Fig. 5, to prevent vlodgment of the. material and providing the discharge-openings L between them. An annular receptacle or bin O surrounds'the column and will be provided with one or more discharge-spente O for the discharge of the crushed material. This receptacle is cast in separable pieces, as shownl in Fig. 2, so ras to be bolted around the column, and the spout or spouts are cast integrally With the sections. The form of crushing-head K shown in Fig; 3 is adapted to fine crushing and is substantially in the shape of afrustum of a sphere, and the surrounding casing has concave walls corresponding thereto. `The form of crushing-head shown in the remaining figures and particularly illustrated in Fig. 8 is in the form of a frustum of acone and is adapted to the crushing of large stones by making the surrounding casing flaring at the top, the finer reduction taking place as the material is discharged.

In Figs. 9, 10, and 11 of the drawings a crusher is shown in which the crushing-chamber is arranged at the base of the machine, and the shaft has the crushing-head provided also at its lower end and its upper end is gyrated by means of the driving-beam,which is operated by substantially the same gearing The driving-beam in this case is supported by the column F; but the shaft is hung by the rods H, connected to the lugs H', which in this in- The upper ends of these rods are connected to a head-block H, which has a ball-aiid-socket bearing, as shown at 7i', Figs. l0 and l1. lThis bearing permits the rods to rock or vi- In this construction the hopper N surrounds the lower end lof the column F. and the inaterialniay discharge into a-suitable receptacle or spout beneath the machine. The principle involved in the use of the two constructions is precisely the saine and the structural adaptations are only very slightly different. We regard both forms as being substantially the same and therefore equally Within the scope of our invention.

In operation the material is placed 'Within the hopper and falls down by gravity between the crushing-headand the annular lining. The driving-shaft being put in inotion, the eccentrics will cause the drivingbeam to gyrate and impart a corresponding motion to the end of the crusliing-shaft opposite the head. The otherend of this shaft carrying the crusliing-head being left free, it will center itself within the crushing-chainber, and the material falling` down between its surface and thesurroundinglining will be crushed on either side of the head. Y.This results from the fact that the material inwerkingits way down after being partly reduced will be wedged between the lowerend ofthe crushing-head and the surrounding4 casing, and as the shaft is moved this material forms a fulcruin over which the crushing-head rocks, thus further reducing the material forming the ,fulcrum, while at the same time 1 the upper end ofthe head forms the initial reduction by impingng upon-the coarsernlaterial between it and the surrounding casing, and the lower end crushes the material on the side that part ofv the head approximates.

This construction and method -ofworking secures' important.advantages,which may be summarized aszfollows: The crus-hing is effectedon oppositesides of thehead `simultaneously, alternating with theinovement of the lower end of the shaft, and as this movement causes .a slight rocking around the ver- 1 tical axis of the crushing-head it will .therelfore give a vertical movement to the periphery of the crushing-head at thebase sufficient to prevent the packing or clinging of Athe material where fine crushing is, desired.

It is obvious that the shorter .the crushinghead the greater the leverage will 4been the material to be crushed, and thatthegreaterthe diameter ofthe head the greater will be the vertical movement at its periphery.

Of course we do not limit our invention, to the details of construction of the several parts, as variations may be made in a the structural features without departing. from the spirit of our invention. The drivingbeam may be operatedby means of asingle eccentric. v
