STONE CRUSHER.
My invention relates particularly to stone Crushers, and has for its pricipal object to provide a stone crusher of relatively light and simple construction which may be easily assembled and taken apart, and which when assembled is of the requisite strength and durability to withstand the rough usages to which machines of this class are frequently subjected.
The several features of the invention will be clearly understood from the following description and accompanying drawings, in which,
Figure 1 is a longitudinal sectional view, partly in elevation, of a stone Crusher embodyinn` the features of the invention in their preferred form;
Fig. 2 is a rear elevation of the same; and
Fig. 3 is a detail sectional view taken on the line 3`3 of'Fig. 2.
The stone Crusher illustrated in the drawings is of the type having a. stationary crushing member 2 and a cooperating movable crushing' member 4. The stationary crushing' member2 comprises a rectangular steel plate which is secured in upright position on a support or header 6 that extends between the sides 8 of ther frame `of the machine. `The movable crushing member 4 comprises a steel plate suitably secured on a carrier 10 which is pivotally mounted at its upper end on a shaft 12 having` its ends mounted in hanged bearing blocks 13 removably secured to the side frames. The carrier 10v is swung back and forth to cause its crushing` plate to cooperate with the stationary crushing,` plate 4. bv means of a driving' shaft 14 having its ends iournaled in bea-rings in standards 9 and is driven by means of pulleys 16 secured on its ends. The connection between the jaw carrier 1() and the driving shaft 14 comprises an eccentric 18 formed on the shaft that'enaaaes an antifriction roll 2O on the free end of a lever arm 22, the roll beingl heldin engagement with Serial No. 611,276.
10 by means of a link 32 in the form of a flat bar having its longitudinal edges suitably seated in sockets in blocks 34 which in turn are removably mounted in sockets in the arm and in a. lunr projecting from the. lower end portion of the jaw carrier. VWith this construction upon rotation of the driving' shaft 14. the lever arm 22 acts to swing the lower end of the iaw carrier 10 back and forth so as to cause the crushing; plates 2 and 4 to cooperate to crush and'expel material placed between them. Except as hereinafter described. the parts above referred to may be and preferably are of a well known construction.
In my improved crusher, the support or header 6 is made .separate from the side frames 8, and these parts are adapted to be easily assembled and disassembled. As
' showm the side frames are made up of steel plates which are detachably secured at their forward ends to the standards 9 by bolts 86, and at their rear ends to the support or header 6. The header 6 consists of a castingr having rearwardly projecting iside flanges 38 and reenforcing ribs 40 extending between the flanges and spaced apart. The flanges 38 have proiectina portions 41 at the top and bottom thereof that are secured to the side plates 8 by short bolts and nuts 42 passing through apertures in these parts. The intermediate portion of the header is secured to the side plates 8 bv bolts 4 4 which extend completely across the header and between the reenforcingribs 40. The bolts 44 extend through axial apertures in Athimbles or bushings 48 that are mounted in registering apertures in the flanges 38 and the side plates 8. These apertures taper inwardly and the bushings 48 have a corresponding taper so as to closely fit the aperf tures. The bolts 44 are provided with nuts 50 that engage the outer ends of the bushings so that by tightening; the bolts, the bushings may be forced tightly against the walls of the apertures. With this construction it will be apparent that no shearing strain is placed on the bolts 44 during, the operation of the Crusher; that all of this strain is effectively borne by the bush-ings 48 which are of large diameter; and that the bolts 44 effectively prevent the side plates from bulging or spreading. The bushings are easily made to fit the apertures, and the bolts 44 pass through the bushings so that it is not necessary to accurately line up the bushings or theapertures in which they are seated, at opposite sides of the header. The header may be easily removed by removing the bolts 491 and 44 and knockingout the bushings 48. Thus a simple, strong, rigid and durable knock-down construction isprovided for securing the header and side plates together, so that these-parts are Capable of resisting the great strain to which they are subjected during the-operation of the Crusher inas effective ar manner as though: they were cast together asa unit as heretofore.
Thesemachifnes are` oftenexposed toy dust, daanpness and rain Lforlonzg periods, and it hars-been found after they machinehas been in use for someV timeV that the actuating lever arm-22 is liable tox become so` rusted orY otherwise'set to its rock shaft 30 that it isfqu'ite impossible to remove these parts without cutting olf the ends of theisha'ft inside of the side' frames of? thev machines, which of course is objectionable. To ove'rcomethis difdcult-y of vtheY prior constructions, the wallk of the borc of the lever 'armaQZ of the machine illu-strated'i-n the d 1a'wings is provided with a cored out portion orrecess 52? extending substantially 180'o of its peripheral length and the wall ofthis cored out portion is provided `witha se-riesof longitudinally ei;-
'"" out portion-52 is sol located, as will be apparent from an inspection of l of the drawings, that the remaining portion of the walll of the bore receives substantially all of the strain of the farmi-on the shaft during the operation of the machin-ei, materially noV stra-in bein-g placed on the babbitted cored outA portion of the bore of the' arm.
lilith this constructionwhen it is desire-d to remo-veltlieshaft an-d arm as is frequently necessary forthe-purpose of repair or shipment, the babbitt may be melted by means of a torch or other-suitable mea-ns, which en'- ables the hub'- of the arm to be knocked rearwardly so: as to disengagetheunbabbitted rear portion of thewall ofits bore from the'shaft and loosenlthe-ley29 from its slot, whereuponthe shaft may beeasily slipped outof its bearings ontheside plates 8, and the arm and shaft removed from the machine.
As will be evident to thoseskilled in the art my invention permits of various modifications without departing from the spirit thereof or the scope of the appenoed claims.
