Claims. .1.
This: invention relates to! rock crushing machines andfhasfo'rl it's'object' toprov'ide' a simple and inexpensive machine capable of withstanding'thevsevere strain such machines are subjected wanting the rock' crushing operation.
one o'f'th'e difiiculties encountered. in the use ofsuch machines is'that the fine dust developed during; the crushing operationsettles in the moving'partslofthemachine thereby not only to affec't'the smoothioperation of the machine but alsoisubjecting it to.excessive wear. In view of th isyitisi aIfliTtliefobjt-Of the invention to rovideai machine-thatis sosimme that it is com parat ively easy 'tolpro'tect the I bearings" surfaces thereof. from "penetration, of. suchflfine dust and s'bsubstantially topromng the life of the machine. These and otherpbjects', as well as the many otheradvantaged'u's features of the invention, will become apparent-fromthe following detailed description and by referring to the accompanying drawings, of which:
Fig. l is a cross sectional view substantially through the center of a device embodying the invention;
-Fig. 2 -is asectional end view of themachine taken on line 2-! bfFigJ 1;
Fig. 3 is an enlargedview of the'cente'r portion of the device appearing in Fig. 1.
Referring in the first instance to Fig. l, the device illustrated comprises end plates l and 2, in. combinationwith-cross braces-3 and 4,- which tie these two end plates togetherto form a -solid framing. Pivot rods E'and 6--bridge the space between the endplates. through which they extend and in which they are preferably tightly seated. Plates 1, 8 are fitted with perforated lugs at the top thereof which ride on the rods 5, 6 and the position of these plates is adjustable by means of set screws ll, i2 of the cross braces 3and 4. When so mounted, these plates form the jaws of the device. 7
A crusher head I is mounted for oscillation within the framing, on a pivot shaft l6, and oscillations of this head are effected through the medium of an eccentric H, which forms part of a shaft ill. The latter is mounted above the shaft IS in parallel relation thereto, and it is by means of a pulley l9 connectable with a suitable prime mover. As the eccentric I1 rotates in response to rotation of the shaft IE, it is seen that oscillating movement is imparted to the crusher head about the pivotal shaft IS.
A suitable hopper 22 is affixed to the top of the frame members I, 2, in which rock to be crushed is dumped in the first instance and from which such rock settles betweenthe faces of the crusher head and the inner" surfaces of the jaws 1-,;8. These spaces are adjustable by means of the screwsll, l2 to deter-mine the size of the'discharge openings 23, 24 at the bottom of the crusher head. The two jawsand the crusher headv may be made from material hard and tough enough to withstand the pressure andgrinding action of the descending rocks, or if not commercially practical to make thecrusher head; out of such hard materiaLit may be preferred" to mount on the side faces thereof liners Z5-and 26, which, when they begin to show wear, may be readily replaced.
The eccentric H is in this case'set off a-short distance from theverticalcenter line of the pivotal shaft is and it carriesan armu28 which'is pivotallyhungon-a pin 29seated-in a stationary lug. 39. Rotation'of theshaft I8- imparts rocking movement of the headabout the pivotal shaft i6.
An important it feature of this-modified device is that a large open space is provided within the crusher head 21 andth-is space forrnsa reservoir for :suitablelubricants. One of the screws, by means of which the component parts of the crusher head are clamped together, is madetubulareas indicated at 33 and the lower extension 34 of this screw reachesnearly to the bottom of the reservoir. Lubricants-maybe fed-through this screw from time toitime as required'and a-suitable plug-35 isdriven or screwedinto the entrance to the-passage throughthescrew to seal it against dirt-and -dust carriedby the. rocklumps which are fed into the hopper 22. It is also important to note that a passage 32 carries lubricant to the pivotal shaft I6. In such manner, all the internal moving parts of the crusher head may be kept completely lubricated at all times and wear on theparts substantially eliminated.
When such combination is provided, it is found that the machine will operate smoothly and when the eccentric, the pivotal shaft and the pin 29 are seated in bearing bushings and the parts are all tightly fitted within the side plates of the machine it is found that little or no opportunity is afforded for fine rock dust to settle in the bearmgs.
While I have in th foregoing described preferred forms of the invention, I reserve the right to embody further modifications within the scope of the claims hereto appended.
