It will henoted-ironrFigure 1 that the rollers arev y arranged in a triangle and that the cane is fed -in through the chute 21 so that it may pass between the rollers and 16. From these rollers the cane passes through the rollers 16 and 17 and' finally out through the discharge chute 22.
In order that the crushed or partially crushed cane may freely, pass the rollers 15 and 17, a guide or conveying block 23 is provided which may bea casting and which is provided with upstanding guiding flanges 24 and 25 adapted to straddle the roller 16. A plurality of notches 26 are arranged in one edge whereby a toothed structure is pre sented, said nitches being provided so that the cane may Ibe properly guided to the roller-` 17 while the From Figures 3 and'4, it will be noted that the block 23 is provided with a) pair of depending bearinglugs 27 for receiving the respectivesupporting bars 28 and 29,
each of whichhas an adjustable bearing pin 30 at the bottom resting on the respective bearing blocks 31. The block 23 also is provided witha pair of depending arc-shaped arms 32, thelower ends ofwhich accommodate a friction' plate 33 adapted to .bear
Vpress more or klessv firmlyV against the roller 15, which pressure is augmented somewhat by the downward pressure of the cane as it passes over the Y guiding block 23. Also, meanshave beenprovided for holding the block 23 in'place and the friction `pl-ate34 properly .pressing againstthe roller.
This means consists v"of a pair of links 35, there being onelink arranged at each end oftheblock 23. Each of these links is provided with an elongated opening 36 accommodating the Vrespective Vjournal pins 37 ex- V tending from the ends of the block 23.` The 38 and' arranged to straddle part of the links l35' while `substantially onthe diametrically end of the link opposite that'carrying the Y slot 36 Vis provided with fa comparatively large aperture designed toV accommodate the disk 38 which is provided with an eccen trically positioned aperture through which the shaft 2O extends. A pair of small guiding plates 39 is rigidly securedto the disk oppositer side isl arranged a U-shapedmember 40 having the legs riveted or otherwise secured to the disk 38. -The U-shaped member V40 carries a set'screw 41 which is adapted to be screwed down and pinch the linksV 35 so as to lock the disk 38 and the links 35 together. .In case of wearing ofthe rolljuice may drop .downv `into the pan 2.
er 15 or of the plates 33 and 34, screw41 may Vbe loosened andv the eccentrically mounted disk38 rotated somewhat until the parts aretight and then the set screw 41 tightened. In this way, the position of the block 23 and associated parts may be readily adjusted totake care of wear or to provide any desired tightness or looseness of connection. f
When the Crusher is in'use, cane is fed into the chute 21 and as it movesbetween the rollers 15 and 16, these rollers mayseparate somewhat if the supply is great, said separation causing the levers' 7 to swing butby reason of the arrangement of the weight 14 and associated parts,.a. continued even pressure will be supplied. As the crushedor partially crushed cane passes the roller 17 isi'rornthe.l roller 16. This'will cause a,` preliminary; crushing vand .then .a final crushing. f
yrollers 15 .and 16,V it will engage thevblock In order to adjustthe .rollers in respect. i
. to the levers 7, any desired number of bolts 42'extend through suitable apertures in thev y -eccentrics 6 and through vthe respective levers 7. By'removing these bolts and shifting the eccentrics. 6 and then-re-applying the bolts different adjustments may be se# cured. lleretofore it has been difficult to properly guide the cane from the roller 15 to the roller 17 and'quite` often Vthe lmass of crushed or partiallycrushed cane would accumulate betweenthese two rollers and prevent-aV proper functioning of the apparatus.
'Byproviding the contact plate 34, a substantial shaving action of *roller 15 will Ibe provided and Uhe'matter thus shaved fromV the roller A15vwill freely pass over the block 23 to the roller 17 without clogging any part ofthe mechanism and the finally crushed cane or pulp will be discharged out vllthe chute 22.
In Figures7 and 8 a slightly modified construction is shown in Vrespect-to the guiding block 23. In this form of the invention'` it will Vbe observed thatgthe block 23y is provided merely with a shaving 0r wearing plate 34f'and the plate 33-'is-eliminated. It
will also be noted that in thisform of the invention a rsingle integral lug 43 extends `from the lower'part vof the block 23 and projects through a bracing bar 44, whichl bar is connected in any desired manner with the supporting bars 28 and 29. A nut 45 is screwed Vonto the lug 43 so as to clamp the parts firmly together while allowing the Vbars 28 and 29 to rock freely'in Vthe respective supports 31.
What I claim is 1. A crusher for cane mills, comprising three crushing rollers arranged in a triangle, a pair of levers connected With each of the two lower rollers, means including a flexible member and Weight acting thereon co-acting with said levers and rollers for automatically causing the levers to swing the lower rollers toward and from each other, and means for guiding vcane to said rollers.
2. In a cane crushing apparatus, a plurality of crushing rollers and guiding means for guiding cane from one roller to the other, said guiding means including a. guiding block having a plurality of notches, and a pair of depending arms, a, pair of roller engaging plates connected to said block and to the arms thereof, means for holding said plates in frictional engagement With one of said rollers, and means for supporting said block While allowing a limited swinging movement thereof.
3. In a cane crushing apparatus, a plurality of crushing rollers and guiding means for guiding the cane from one roller to the other, said guiding means including a guiding block frictionally engaging one o-f the rollers, means for supporting the block, and means for holding the block against one of the rollers, said last mentioned means including a pair of links pivotally connected With the block, an eccentrically mounted disk rotatably mounted in each of said links, and meansfor locking the disks in different positions in respect to the links. Y
4. A cane crushing apparatus of the character described, comprising a fixed crushing roller, a pair of movable crushing rollers co-acting with the fixed crushing roller, each of the movable crushing rollers having a shaft extending therefrom, eccentric members mounted on said shafts, abearing block for each of said eccentric inembers, a pair of levers for each of said movable rollers, means forclainping the eccentrics to the respective levers so that when the levers are lswung back and forth the eccentrics will be rotated and the movable rollers Will be moved substantially toward and from each other, a pulley carried by each of said levers near the upper end, a chain secured to one of the levers and reeve over said pulleys, and a Weight actv ing on said chain for pulling the same so as to give the levers a tendency to move towards each other and consequently swing said movable rollers toward each other.
