ROBERT KILLOCH DONALD, OF VICTORIA ROAD LOOH, VICTORIA, AUSTRALIA.
CRADLE CRUSHER.
Specification of Letters Patent.
Patented Jan. 12, 1909.
Application filed April 26, 1907. Serial No. 370,466.
To all whom it may concern:
Be it known that I, ROBERT KILLocH DON- ALD, a subject of the King of Great Britain, residing at Victoria Road Loch, in the State of Victoria, Australia, engineer, have invented Improvements in Cradle Crushers, of which the following is a specification.
This invention relates to that kind of machine known as cradle Crushers which comprise a rocking trough, in which rests one or more loose rollers, while the ore is automatically fed in at one end, along with a flow of water, and out at the other end through a screen on to the separating tables.
The object of this invention is to provide means for readily fixing, removing, or adjusting the liner plates, in such Crushers while a further improvement consists of feeding the ore under a series of rollers, the first of which is lighter than the others, in order to obtain a more satisfactory crushing by the adjustment of the weights, to regulate the motion of the rollers.
Thedrawings illustrating the invention comprlseg-Figure 1 a side elevation of the trough: Fig. 2 a half cross section and half end elevation thereof, and Fig. 3 a side elevation of one of the narrow bars hereinafter referred to. Fig. 4 is a broken end elevation showing the rocking means for the cradle.
Referring now to these drawings, it will be seen that the liner plates, which are provided for each roller are formed of one or more parts or sections, although shown in three sections 1, 2 and 3 on the drawing, and said sections are held in position by narrow longitudinal bars 4, 4, extending the full length of the trough 5, and bearing on the top sections of said liner plates. These narrow bars 4, 4, are recessed as at 6 from the top edges to receive the ends of transverse guide bars 7 which accomplish the dual function of guiding the loose rollers when revolving in the trough and holding the liner plates in position. lThe sections l, 2 and 3 of the liner plate, after being placed in position in the trough, are thus held positively against displacement by the bars 4, which cooperate as clamps for said sections, the abutting or conterminous edges of the sections and the bars 4 bearing frictionally against one another.
The guide bars are situated between the liner plates and rollers except the end ones which are between the end rollers and liner plates and the ends of the trough. The liner as it passes through the Crusher.
plates are thus separated from each other and the grooves or recesses 16 formed thereby may be utilized for amalgamating gold Said guide bars extend through the sides of the trough into a box-shaped casting 8 or the like formed thereon. Bolts 9 are screwed down through said casting and bearing on the guide bars cause same to press the narrow bars 4, 4, down upon the top sections 1 and 3 of the liner plates thus firmly binding all the sections of the liner plates together and securing same in position within the trough. Other bolts 10 are passed through the box and preferably through slotted holes therein so that said guide bars may be adjusted.
The narrow bars 4, 4 are secured in position against the sides of the trough by screwed bolts 11 extending through slots 12 formed in said sides and said screwed bolts are tightened when the liner plates are lixed in position. It will thus be seen that by loosening the screwed bolts 11 of the narrow bars 4, 4 and unscrewing bolts 9, 10 against guide bars 7 said narrow bars may be lifted out or off, and the sections of the liner plates removed for replacement or for cleaning purposes.
The rollers which rest upon the liner plates are of varying weights that of the rst 13 being the lightest while the others 14 and 15 are heavier or of successively increasing weight towards the discharge end of the trough. The variation in the weight of the rollers is preferably obtained by the casting of the cores thereof or by varying their lengths or width or by any other suitable means. By this arrangement of the different weight of the rollers a uniform travel can be arrived at giving the maximum, crushing power of the rollers.
In Fig. 4 is shown means for rocking the cradle which comprises a crank disk 17 attached by links 1S to beams 19, the latter connected to the cradle which has trunnions 2O mounted in bearings 21 forming the fulcrum point for said cradle.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a cradle crusher, in combination, a rocking trough having a liner plate formed of a plurality of independent sections, longitudinal bars arranged at opposite sides of said trough and bearing against the edges in, transverse divisionbars of said sections to confine them, division bars extending transversely. of the trough and having a bearing upon the longitudinalbars, retaining means for the division bars, and crushing rollers resting on the sections of theliner plate and confined between the division bars as guides.
2. In a cradle crusher, in combination, av rocking trough, a liner plate therefor, means detachably secured tothe trough and bearing with. a clamping action against the edges of the liner plate' toA confine the same, and a crushing roller confined' in the trough and restingv upon the liner plate;
3. In a cradle crusher, in combination, a rocking trough, a linerv plate therefor comprising'a plurality of independent sections assembled? in continuity, means detachably securedi to theltrough and bearing upon opposite edgeslofsaid' plate to confine the sect/ion's as` aseries, and a crushing roller confined in the trough and resting upon the liner' plate;
if. InI a cradle crusher, in combination, a rocking'trough, a liner plate therefor, bars arranged at each side of the trough, longitudinally thereof, and bearing against thev adjacentl edv-es of the linerplate` to conne the same, saidbarshaving recesses formedI therepassed through correspondingly located recesses in said longitudinal bars, boXings provided at the sides ofthe trough to receivethe end portions of said division bars, and means for adjusting the division bars, vertically of the trough, in said boXings.
5. In a cradle Crusher, in combination', a rock-ing trough, spaced parallel guide bars mounted transversely of the trough and a plurality of independent rollers loosely mounted in said trough and spaced from one another by said guide bars, said' rollers being of successively increasing Weight With respect to one another;
6; In a cradle Crusher, 1n combination, a .f
rocking trough, a liner plate therefor, bars arranged adjacent the side edges of the trough longitudinally thereof andi bearing against theed'ges-of the liner plate, said bars serving as a clampingmeans for said plate retainingy meansfor saidf bars, and' a crushing roller confined in the troughand resting upon the liner plate.
In testimony whereof I have hereunto set my handl in presence of tWo subscribingk Witnesses.
