The object of the-invention is to providel various improvements in the construction 0f large gyratory crushers which will increase the efficiency of-the machine and at the same time simplify the construction thereof. Q 'Y A Some of the features herein disclosed are claimed broadly in a divisional application S. N. 789,385, filed 'Sepe 11, 1913.
A clear conception of the invention can be obtained by referrin to the accompanying drawings in which ike reference chara'ters designate the same parts in different views.
Figure 1 isawcentral vertical section of a gyratory Crusher with the improvements applied thereto. Fig. 2 is an enlarged plan View of the suspension collar for the shaft. ,Fig 3 is a plan view of the lining used in the bottqm shell. Fig. .4 is a central vertical section of the lining shown in Fig. 3 with the addition of fragmental sections through openings. Fig. 5 is a central vertical section of the lining taken on a line at right angles to the line of sec- \tion of Fig. 4. Fig. 6 is an enlarged fra mental section of the top shell and spider. F 1g. 7 is a similarviewtaken through another portion of these elements. Fig. 8 is a fragmental plan view of the spider. Fig. 9 1s a plan view of the spider wedge block. Fig. 10 is a sectional view of theshaft on the line X-X of Fig. 1, lookingfin the direction of the arrow.
The gyratorycrusher consists essentially of a main shaft 1, carrying the head 44, and is suspended from the spider 10. The s ider 10 is rigidly connected to thel top she 1'12, whose interior is lined with concaves 45. The tgp shell 12 rests upon the bottom shell 16; to which is fastened a bottom late 140.
The lower bearing of the main shaft 1 is 1 Specification of Letters Patent.

formed in t-he bottom plate 140, the bottom plate 140 and cover 41 forming an oil chamber about said bearing.
The main shaft 1 is suspended from the spider `10 by means of a split suspension collar 4, see Figs. 2 and 10. This collar 4 is fitted into a roove 3 which is turned into the main shaft 1 at its upper end 2. The keys or feathers 18, which coact in the slots 81 of the collar 4, positively prevent the collar 4 from turning on the shaft by fitting the keys or feathers 18 into keyway 181 formed in the shaft 1 at the groove 3. The two halves of the collar 4 are clamped together by the bolts 5, see Figs. 1 and 2 thereby locking the key in place in the groove.
A wearing ring 8, having a spherical zone surface on its lower side, coacts with a corresponding convex upper surface of the spider bushing 7 on its lower side, and with a lower surface of the collar 4 on its upper plane surface. The spider bushing 7 which is supported in the spider 10 has a tapered bore 9 through which the main shaft 1 passes. Av suitable dust cap 6 is provided over the working parts just described, and rests on the top of the 4spider 10.`
The spider l0, see Figg 1, 6, 7, 8, may have any number off-'arms desired. As shown in Fig. 1, there are four arms, two being shown, while Fig. 8 discloses a fragment of a two arm spider 10. The arc shaped bases 1l of the spider 10 are slightly tapered convergingly on their inner surfaces, and coact in a corresponding roove in the upper portion of the top shel 12, and
g are also tapered convergingly upwardly at their ends. This groove is concentric with the Crusher, the portion of the groove which is not filled by the spider bases 11 being filled by the spider wedge blocks 40. These wedge blocks 40 are tapered convergingly downward on theirinner and end surfaces, and are of sulicient length to form a wedge between two bases 11 when the wedge block 40 is inserted between them thus circumferentially wedging the bases 11 of the spider 10 within the top shell 12.- The bolts 29, 30, are used for securing the spider 10 and wedge blocks 40 to the top shell 12, these bolts 29, 30, being locked into place by lock nuts 31, see Fig. 7. A series of standard or stock bolts'13, not specially machined material to befcrushed is fed uponn the conand carrying'the 'nuts 14, are aed through cored holes in the to shel 1 belowt e bases 11 and the we ges 40, and serve as jack screws, sce Fig. 6. The cored holes through the top shell 12 have square recesses to accommodate the nuts 14;
'lhebottom shell 16 forms a support for a nection between the two opposite sets of lin- l ois 19, 21, and they are laterally curved to provide a recess for the shaft 1. Of the upper liners 22, 23, 24, the inner and outer liners 22,24, have-their corresponding inner and outer edges formed with sidewalls 27, 2e.. l z
The bottom shell 16 also forms a coverin for the driving gear 17 and the gear hi 35 to which the gear 17 is attached.' This gear hub 35 is inon'e piece with or rigidly connected to the eccentric 37, through the eccentric hole of whichvthe shaft 1' passes as usual. The upper portion of the hollow gear hub 35 is conical in shape and extends nearly u to'the shaft 1, thus (forming the oil cham er 36. A strip Aof falligic 42- is fas.
tened to the shaft 1 in any con enient manner, as by tyin same thereto atits upper ond by means o cord 421,-* and the fabric 42 hangs down over the conical ortion of the hub 35 lto form an apron.. T e u'sliing 39 which is fastened to the bottom late 146, forms the .supporti-for a wearing ring 38 gear hub 35 bears. 5
In operating t e crusher, the shaft 1 is inion', not' shown, which meshes with the driving geargf'f. The
caves 45 and .is crushed by :the action of the 1 and eccentric 37, and as it is furthermore head 44, which has a gyratory motion by the rotation 'of the eccentric 37. Upon leav-4 ing the crushing members, the crushed material falls .upon the. section D lining from which it is discharged by it spouts 2 8. This sectional lining is casi y removed, due to its ,sectional construction, which is a great advantage in case ofrepairs.
As it isv necessary to keep a constant flow of oil around the lower bearing of the shaft essential to' kee some means o 36 must be provided: This inclosure .is
gritty matter from this oil,
formed by the -conical portion of. the gear hub 35 and the fabric strip 42. The upper portion of the chamber 36 1s formed conical so as to defiectthe oil which rises diie to the he dischar e l mclosing the oil chamber centrifugal force, inward toward the shaft 1, from which it passes back to the bearing. The conical hub 35 is not made to touch'the shaftv 1 because the latter is not machined at this point. If the shaft were machined there could be a tight fit atthis point as the justable.
It is ordinarily diiiicult to remove the spider7 10 from the-to shell 12. To facilitatethis removal 'the olts 13 are-provided.
-for breaking the joint between the top shell 12 and the bottom shell 16 when Ithese members are large and heavy.y These are not shown in the present construction, but their arrangement would be the same as that of the bolts 13 which are shown. 1-
