To all whom it may concern:

Be it known that I,=CHARLEs L. CARMAN, a citizen of the United States, and a resident of the borough and county of Bronx, city and State of New York, have invented certain new and useful Improvements in Crushers, of which the following is a speci-- fication.

This invention relates to crusher apparatus for crushing stone, ore or other material, and relates particularly to crushers known as gyratory crushers, and it is the object of the invention to provide improved driving means to impart gyratory movement to a gyratory crushing member in this type or crusher which is novel, simple and cheap in structure, and highly efiicient in operation. r

llt is another object of the invention to provide improved driving means supported independently "of the gyratory crushing member orits support and arranged to be detachably; connected or coupled to the gyratory crusher member.

It is another object of the invention to provide in a gyratory crusher in which the gyratory crushing member is eccentrically mounted in a bushing concentric with the axis of the crusher improved driving means supported independently of the crushing member or its bushing and adapted to be operatively connected to the bushing at one end thereof concentrically with the axis of the crusher.

It is a still further object of the invention to provide an electric motor drive 'for crushers of this type with the rotatable member of the motor supported independently of the gyratory crushing member and arranged with detachable means-to operatively connect the same to the gyratory crushing member.

It is still another object of the invention to provide improved driving means su ported concentrically of the crusher on t a bearing support of the crusher independently of the gyratory crushing member or its bearing, with means to operatively cohnect the driving means to the gyratoryucrushing member or its bearing and co-operate with the support for said bearing to provide an enclosed lubricant carrying housing for said bearing.

Other objects and advantages .will hereinafter appear,

In the drawings accompanying and forming a part of this specification Figure 1 is a sectional side elevation of a gyratory crusher showing an embodiment of my improved driving means applied thereto.

Figure 2 is a sectional side elevation showing a modified torm'of driver and manner of connecting the driver to the gyratory crushing member. Figure 3 is a sectional detail view showing a modified method of operatively connectingthe driver shown in Figure 2 to the gyratory crushing member.

Figure 4 is a perspective view, partly in section, of a bearing in which the gyratory crushing member is eccentrically mounted.

Figures 5 and 6 are detail views in perspective of the means shown in Figure 1 to couple the driver to the gyratory crushingmember. I

. Figure 7 is a plan view of a ring for supporting the driver upon the bearing support of the gyratory crushing member as shown in Figure 1; and

Figure 8 is a bottom view, partly in sec tion, to show the manner of mounting the driver supporting ring.

Similar characters of reference designate like parts throughout the difierent views of the drawings.

In the embodimentof my invention shown in the drawings the operative mechanism of the crusher is supported by a main frame or supporting base 7 arranged to besupported upon a suitable'foundation. A crus ing member 8 in the form of an annular shell or chamber is mounted upon the base and is provided with segmental sections of wear resisting material 9, upon the inner face. This chamber may be of cylindrical term as shown, or as commonly made of inverted truncated cone shape. A shaft 10 is fulcrumed, at at 11, concentric with the a ris of the chamber 8 in the hub of a spider 12 mounted upon the crushin chamber, said shaft having a crushing hea or member 13 of truncated cone shape mounted thereon with the peripheral wall thereof in opposed I material and dust from passing into said sleeve.

A hearing supporting sleeve 18 is carried by the bottom plate 19 of the supporting base.

7 concentric with the crushing chamber 8, which sleeve may be cast integral with said base, but to facilitate the machining and replacement of said sleeve it is preferably made separately from the bottom plate 19' and secured in an opening in said bottom late to extend above and below the same by bolts 20 passing through a lateral flange of said sleeve and the bottom plate. A hearing member or bushing 21 is mounted in the bearing sleeve 18 to rotate on an axis concentric with the axis of the crusher and shell or chamber 8, said bearing having a bearing face on the interior thereof eccentric to the axis of rotation of the bearing and crusher, said bearing face being of globular or socket form as shown at 22 for the engagement of a circular or ball portion 23 of a bushing 24 in which the shaft 10 is loosely mounted and to have axial movement. To facilitate the mounting of the bearing for the shaft in the bearing member 21 this bearing is made of longitudinally split sections re easably secured together by bolts 25 passing through opposite rib portions 26 extendin transversely of the axis of the bearing and at the end of the shaft 10. The ball and socket portions 22, 23 of the bearing-21 and bushing 24 are so arranged as to bring the line of force of pressure of the eccentric coincident with the center of the bottom plate 19 of the supporting base 7. By this arrangement gyratory movement will be imparted to the shaft 10 and through the shaft to the crushing head 13 by the rotation of the bearing 21. -A dust collar 27 is also mounted upon the shaft at the end of the bearing sleeve 18.

To rotate the eccentric bearing member 21 driving means are provided consisting of a driver or driving unit rotatably mounted or journalled upon the bearing sleeve 18 below the bottom plate of the base 7 concentric with the axis of the crushing apparatus and independently of the crushing member. This driver as shown in Figure 1 of the drawings comprises an electric motor having a rotatable annular field or rotor 28 and a stator 29. The rotor is carried by a s ider 30 having a central hub portion where y it 36 is detachably is rotatably mounted or journalled upon the bearing supporting sleeve 18 and is held against endwisemovement by one end of the spider hub engaging a shoulder formed in the supporting flange of the bearing sleeve and a collar 31 removably mounted at the end of the bearing sleeve, said collar also serving to support the superimposed load of the driver and eccentric bearing. To removably mount the ring or collar 31 upon the bearing sleeve the bearing sleeve is arranged with an annular recess or groove 32 having segmental slots 33 cut thereinto from the end of the bearing sleeve, and the collar is arranged with segmental inwardly extending pro ections 34. To apply the collar it is adjusted to register the projections 34 thereon with the slots 33 to cause the collar projections to engage the annular groove or recess 32, and as said collar projections engage in said recess the collar is rotatably adjusted to seat the collar projections 34 upon the shoulders formed by the slots 33 cut in to said annular recess when it is secured in such position by a set-screw or pin 35.

It will be obvious that the supporting The stator 29 is fixed to the bottom plate of the supporting base 7 Within and concentric of the rotor.

By the mounting of the driver as described the driver encircles the bearing sleeve and eccentric bearing and to operatively connect the driver to the shaft 10 and ratory crushs ing member 13 at the end of said shaft concentric with the axis of the crusher a plate or disk 36 (Figure 5) is detachably secured to one end of the hub of the rotor carrying spider, as by bolts, said plate serving to close one end of the opening through the spider hub and also the opening in the bearing sleeve 18 thereby providing a closed lubricant carrying chamber for the bearing.

To operatively connect the driver with the gyratory crushing member, a plate or.disk connected to the driver by bolts passing t rough perforations circumferentially d1sposed in the plate adjacent the periphery and threaded into the driver. The 1 plate is arranged with a rib 37 projecting of the disk for the slidable engagement of the obvious that 1 have provided a driving means for the gyratory member of the crusher which is supported independently of said member or its bearing and which is operatively connected to the gyratory crushing member concentric of the axis of the crusher at one end of said member, the eccentric bearing for the yratory crushing member being supported by the driving means, and by this arrangement of mounting the driving means and connecting the same to the gyratory crushing member that the eccentric bearing for the gyratory crushing memher may be readily removed without the necessity of disturbing the. driving means. f

While I have described the driver as consisting of an electric motor this driver may comprise a rope or belt driven pulley, as shown in Figures 2 and 3, in which case a pulley 42 is substituted for the electric motor, and the pulley may be operatively connected to the eccentric bearing for the gyratory crushing member in the manner shown in Figure 1 through the intermediary of the plate 36 and interposed coupling disk,

39, or directly and rigidly connected to said bearing in a manner as shown in Figure 3. For this purpose the bearing 21 is arranged below and overlap the rotor carrying spider and secured thereto as by bolts, the opening in the bearin being closed by a plate 45 secured to the icaring flange t3 and cooperating with said flange to provide a lubricant carrying chamber for the bearing.

In Figure 2 I have shown a modified means of connecting the eccentric bearing 21 to the driver. The driver is connected to said hearing by a plate 46 bolted to the hub of the driver similar to the connection of the plate 36. The plate 46 however has an inwardly projecting hub 47 havinga lateral lug 48 arranged with a longitudinal slot. The bearing 21 has an inwardly extending lug49 with a slot adapted to register with the slot of the hub lug 48 and in which regis tered slots akey or feather 50 is adapted to engage, said key being secured in the slot of the hub lug 48, as by a bolt 51, and being of less width than the depth of the slots in the lugs 48 and 49 to provide a space between said key and the bot m of the slot in the bearing lug 49 thereby permitting of movement laterally of the axis of the crusher to compensate for 'lwe'ar and otherwise. To facilitate machining of the slotin the lug 48 of the plate hub an opening is provided I in lino with said lug and which opening when the plate is connectedto the driver and bearing 21 is closed by'a plate 51 to prevent leakage of lubricant from the bearing 21.

To provide'a supply of lubricant to the bearing or the chamber formed by the plate 36 in conjunction with the supporting sleeve for said bearing, the stator of the motor shown in Figure 1 may be provided with lubricant carrying chamber the outlet from which is at the upper end of the hub of said spider, and to direct any flow of lubricant rom the upper end of the spider hub into the well 52 an annular deflector plate 56 is provided at the top of the spider hub to extend over the top of the inner wall of the well; The pump 54: may be driven in a suitable manner, and as shown is driven from the rotor by a belt or cable 56 passing around a circular hub portion 57 extending from the plate 36, and late 46, and a pulley 58 connected to the riving shaft of the pump.

As shown in Figures 2 and 3 the. lubricant well is arranged in the pulley 4:2, as shown ubricant carrying chamber is from one end of the hub of the pulley, and the lubricant is led from said Well by a pipe 60 to the top of the bearing sleeve 21, and the lubricant may be elevated to the top of the bearing by inertia of the lubricant through the rotation of the pulley, or a suitable pump may be interposed between the inlet and outlet of the pipe. To prevent splashing and throwing of the lubricant laterally from the well through centrifugal action an annular flange 61 is arranged at one edge of the rim of the pulley to extend toward the axis of, the pulley.
