GYRATORY CRUSHER.
Specification of Letters Patent.
Patented Aug. 11, 1908.
Application filed April 3, 1906. Serial` No. 309,673.
To all whom it may concern:
Be it known that I, CHARLES L. HATHA- WAY, a citizen of the United States of America, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Gyratory Crushers, of which the following is a specification.
This invention relates to improvements in gyratory crushers and has for its object to produce a device in which great capacity and crushing power, durability and effectiveness are combined with simplicity of construction, lightness and ease of operation.
The particular construction of my device furthermore adapts it to all kinds of rocks 'and material, renders the wearing parts readily accessible and provides for convene ient adjustment of the various members of the apparatus. I attain these objects by the mechanism illustrated in the accompanying drawings in the various views of which like parts are similarly designated and in which 'Figure 1` represents a vertical section through the device, Fig. 2 4a composite view showing a plan view and a section taken along a line 2-2, Fig. 1, Fig. 3- a composite view illustrating a section taken along a line 3 3, Fig. 1 and Fig. 4 a fragmentary vertical section through the upper portion of the eccentric taken along a line 4-4, Fig. 2.
Referring to the drawings 5 represents the bed or base of the device by means of which it may be mounted upon a suitable foundation, and which comprises a central, cylindrical body 6 provided with radially extendingarms 7 which support the integral, superposed, annular bottom plate 8.
9 represents the inverted-conically shaped shell or mortar in which the rock or other material under treatment is comminuted and which is provided at its upper and lower edges with parallel, outwardly extending annular, flanges 10 and 11, connected by a plurality of integral interposed webs l2. Shell 9 is furthermore provided with an interior lining 13, made of hardened metal and preferably composed of a plurality of adjoining sections or so called concaves to facilitate adjustment and renewal.
The lower flange 11 of the mortar engages, in practice, the annular bottom plate 8 of base 5 and is rigidly secured thereto by bolts 14, While the upper flange 10 supports four upwardly extending, inwardly inclined standards 15, held in place by bolts 16 and strengthened by webs 17, which extend vertically between laterally ranging cheeks 1S and 19 at the upper and lower extremities of the standards. The latter support the spider-bearing 20, comprising a central cylindrical body portion 21 and four radially extending arms 22, the outer extremities of which rest upon the cheeks 18 and are rigidly secured thereto by bolts 23.
Revolubly mounted upon spider 20, is the horizontally disposed gear wheel 24, provided with an .elongated downwardly extending hub 25 which projects through a diametrically corresponding bore 26 in the central portion 21 of the spider and is held in place by a collar 27, secured to its protruding extremity by set-screws 28.
The power required to actuate the gear during the operation of the apparatus is transmitted thereto from any convenient source through instrumentality of a bevel pinion 29, secured at the extremity of a counter shaft 30, which is revolubly mounted in a ournal box 3l, on one of the arms 22 of spider 20.
The hub 25 of gear 24 has a central bore 32, the upper portion of which is occupied by a sleeve or bushing 33 having an eccentric, obliquely ranging aperture 34 and by means of which a gyratory movement is imparted to the upright driving shaftl 35. Eccentric 33 is furthermore provided with an annular flange 36, extending around its upper end and which, in practice, occupies a corresponding, annular, recess in the upper surface of the hub 25. of stud-bolts 37, while two set-screws 38 (shown in Fig. 4) extending through correspondingly threaded apertures in the flange, engage the surface of the recess for the purpose of facilitating removal of the bushing 33.
The motion of the lower extremity of the shaft is limited, as it extends through a diametrically, slightly larger opening 44 in a bushing 43 which, occupying the upper portion of bore 42, is held in place by a ring 45 let into a recess in base 5 and secured thereto by bolts 46.
A cap 47 resting upon ring 45 and encircling the Shaft, 1s intended to prevent dirt and dust from reaching the contacting surfaces ofy l for the vertical adjustment of the box.
The diametrically reduced upper extremity of shaft 35 extends through the eccentric bore in bushing 33 while the portion of the shaft within the mortar 9 is conically enlarged at 51 to hold the truncated coneshaped crushing head 52 which is provided with a surrounding mantle 53, made of hardened steel and, like lining 13 of shell 9, preferably composed of a plurality of adj oining sections to facilitate renewal in case of wear or breakage.
. The storing capacity of the device may bel increased by a hopper 54, placed abovev the mortar 9 and secured on the inside of standards 15.
A sleeve 55 placed around the portion of shaft 35, extending through the hopper, is adapted to protect the former from wear and damage by contact with the continually agitated mass of rock.
Having thus described the mechanical construction of the device its operation will be readily understood.
The rocks or other material to be crushed 4 is fed into hopper 54 through the spaces between standards 15, an arrangement which positively forbids clogging or bridging of the stones and, as it drops into the mortar, is gradually reduced by contact with the lining 13 and the gyrating head 52 which receives' its movement through instrumentality of the eccentric and the therewith connected gear 24. The crushed rock passing through the throat of the mortar, drops into a chute or other receptacle placed below the device and for obvious reasons omitted from the drawings.
To alter the size of the product or to compensate for wear of the mantle 53 and the lining 13, head 24 may be raised or lowered and the opening between it and the shell in consequence, regulated by vertical adjustment of the step box which, i't should be observed, oan be accomplished without interfering with the operation of the machine or the arrangement of its parts.V A similar advantage is derived when it is desired to renew the sections of the lining of the shell and of the mantle of the head or the eccentric 34,
all of which are readily accessible and may be manipulated lwithout disturbance to other part of the apparatus.
The location of the driving gear in relation to the crushing head provides the greatest leverage at the mouth of the mortar where it is most needed to crush the rocks as they enter in the unbroken condition.
It should furthermore be understood that, by the construction as shown and described, the leverage or in other words, the crushing power of the apparatus, may be increased by replacing the shaft and the standards interposed between the mortar and the spider by others of greater length, in fact if so desired, the legs may be dispensed with and the spider supported on an independent frame work or suitable foundation.
Having thus described my invention what I claim is 1. In a crushing machine a mortar, a crushing head within the mortar, a shaft carrying the head and extending below the lower end of the mortar, means engaging the upper ends of the shaft for imparting a gyratory movement to the shaft and head, means to hold the shaft against downward movement, and means intermediate the lower extremity of the shaft and the head for providing a lateral resistance against the movement of the shaft.
2. In a crushing machine, a mortar, a base supporting the same, said base having a central opening extending therethrough a crushing head within the mortar, a shaft carrying the same and extending down into the opening in the base, an adjustable step within the opening, engaging the lower end of the shaft, a bushing at the upper end of the opening above the step, closely surrounding the said lower portion of the shaft, and means engaging the upper end of the shaft to impart a gyratory movement thereto.
In testimony whereof I have afiixed my signature in presence of two witnesses.
CHARLES L. HATHAWAY.
