CANE-MILL.
To all whom 'Zt may concern:
Beit known that I, ALPHONSE F. DEL- BERT, a citizen of the United States, residin at New Orleans, in the parish of Orleans an State of Louisiana, have invented new and useful Improvements in Cane-Mills, of which the following is a specification.
My present invention relates to improvements in mills especially of 'the type used in sugar making, and it has for its object prima rily to provide an improved housing wherein the sections which sustain the pressure of the rolls are tied or bound so effectually that liability to fracture or breaking of the housing` is minimized, and the size and weight thereof ismaterially reduced so that cost. of manu- -facture and transportation thereof is lessened and the erection of the mills is facilitated, the thorough binding and reinforcing of the housing enabling the lower rollers to be placed more closely so that a turn plate of smaller area and less resistance may be employed;
Another object of'the invention is -to provide an improved inode of mounting the pressure regulator or ram on a housing of the character .above described, whereby it may be convenir-intl accessible and 'a ro' er o 1eration thereof is insured, and to provide iinproved adjustin or locking devices for the turn plate where y the latterlma be adjusted with facility and e'asil locke' to irevent movement thereo-lateraly, vertically or: in an endwise direction. A
To'these and other ends, the invention c'onsists in certain improvements, and combina-' tions, and arrangeiiientsof parts, all 'as will be hereinafter more'full claims at the end of thetspecification.l In the drawing'sligure 1-re.pres ents a constructed in accordance with the present l mill shown in 4s invention; FigZ is an'end elevation of theig. 1, portions of the housing' beingshown in sectionl to illustrate the tie bolts Vforbinding the sections in coperative relation`;.Fig. 3 is a 'detail end view `of the turn plate and its supportin f bar.
Similar parts in the severa figures are designatedby the same numerals of reference.
My present invention, aspreviously stated,
is .especially adaptcdfor use in connection withwmills of theV type usedin' the manufac-- f Spec'teation 'of Lettera Patent.'

'roll 1 and the forward roll 3 in entering the and 13.
described, vthe novel .featuresrbeing pointe out particularly in the4 estantes Aug. 4, isos.v
- turc of sugar, th'e cane being passed between rolls under heavy pressure which serve to express the juice from the cane, and by reason of the excessive pressure imposed upon the rolls, considerable diiculty ias been ex etrienced with the housings which deve op fractures by reason of thevsprcai-hug of the rollers, and it is the primary objectof the present invention to cure thie defect.
'I he mill shown in the present embodiment 0f my invention, embodies a set of three rolls! having' their'axes arranged in triangular re 65 lation, the cane passing between the upper.'
mill, and is then transferredby means o f the turn plate 3 to the rear roll 4, the crushed cane passing from the mill between the rear 70 and upper rolls. v The housings'which serve to support the rolls in proper relation each embodies in the present instance a core or center piece 5 which may be composed o a.
.casting of suitable metal and is mounted on a v base 6 by means of which the mill is supported. The center core thus. provided has a vertically opening box in the. 'top thereof to 'receive the ialved bearing members 8 and 9 which coperate. with the journals Qf th'e up- B0 p'er roll', and the center core is also provided with recesses 10 and 11 .at its front and rear to receive the journals of th corresponding` rolls and their respective journal bearings 12 the latter and the core havi surfaces which engage one 'another when ,t e parts` are in properrelation, and the lower, front and rear s corners of the cores are also` adapted to res-'90 ceive the fr ont and rear vbearing caps l5 and- 416 which are also `adapted to .obtainafrm :seatingagainst the core.V ."These bearing'caps tare preferably composed o f steel sotreated as Y A* yto possess a relativelyhigh tensile strength, en 95 -open hearth steel casting having bepii f ound, rsuitable for the purpose.
Thetendency of the rolls, of course, is to v spread as the cane passe-s betwcen them, the A linesof force in the mill shown acting in triangular relatioii to one another, that is to say, in linesdrawn through the axesof the# lthree rolls, and these strains 'are' sustained according to .the present invention by boltsor' other` devices'of relatively high tensile 1Q`5 strength which extend in directions parallel.
The top of the core suitably ormed 4to receive the upper bearing cap 14,5",
'to the directions of the strains, that is to sav, they Aare .arranged in triangular relation in the presenti instance to correspond to the three directions in which the strains act, and
the binding or tying devices thus providedv cooperate with the threebearing caps to tirmlyfbind them in cooperative relation with the center core of the housing and to wholly sustain the lateral thrust of the rolls. Three pairs of tie bolts IT, 1S and 19 are employed 1n the-'present instance which surround. the center core of the housing and connect. the bearing caps, these bolts being preferably arranged outside of the journals of the rolls l5 and ext-end through openings in the three sidesof the center core. and through registering openings in the respective bearing caps, the ends of each bolt being preferably -provided with nuts or et uiraleut tightening or locking devices wherel ing caps muv be locked iirml)` in cooperative relation with the center core. 'l`he bolts a'ie preferably made of steel of relativelv high tensile. strength, and thev, together with the three bearing caps, sustain the ent-ire sprcading tendency of the rolls, so that the center core which does not receive the tension. may he composed of a relatively light casting.
A housing constructed iu accordance with the resent invention enables the/'presstu'e regu ating ram to be mount ed in att/"improved manner for the reason that the upper hearing capis inl trnt engagementA wit'lrthe center core of the housingr and f 'tatscquently it cannot tiltbv reason of the unequal llucssu'res between thouppcr roll and the front and rear rollsjandthus it atfords a mounting for the rata that will maintain it in alincment and thereby prevent bindingr that would interfere 40 with its movements. ln the present instance the fluid chamber or' cylinder .20 is fortned in'the lower side of the upper bearing cap, the ran't or langer-.21 being arranged to move downwart l v from the underside of the cap and bear upon thc upper-side of thc bearing which cooperatesA with the journal of the upper rolt, the dcgreeof pressure or the range ,of movementof the ram being regulated by liners Z,\\hich ma) be composed of thin sheets` of steel or other suitable material which are inserted in a recess i in the upper side of the bearing. The pressure regulating ram when so mounted is not onl v conveniently accessible for inspection or other pur- 'seaposi t 'I Lv the several bears the bearings which eoperate with the wedges being preferably inclined tio co6 er- `ate with the inclined surfaces `of the'we ges and the outer sides of the latter preferably bearing againsta pair of parallel surfaces 3l yand 3'. formed on the respective bearing caps. l' These wedges mayl be tightened in any suitable way, they being provided with extend toit-he exterior of the housing and are provided with tightening nuts 35 and 36. The turn plate 3 which serves to strip the K crushed cane from the front roll and transfer it to the lrear roll is supported on a cross bar'go' 3T which extends between the housings and vrests inopenings provided therein for the purpose, the plate being inserted in a seat. 3S formed in the top of the cross bar and having a beveled rear edge which cooperates with 35 an undercut wal. 39 at. the rear of the cross bar, a bolt- 4t) extending upwardly from the lower edge of vthe cross bar serving to lock the plate in its seat. l This turn plate is adi 'ust-cd relatively tothe front a-nil rear rolls au, v means of a pair of wedges 4l and 42 having parallel outer sides which cooperate re= spe-'.ftivclv with the parallel vertical walls` 43 and 44 of the openings in the, housing inf which the ends o f the cross bar rest, the proximate sides of the-wedges being inclined or tapered in reverse dircctionstoeoperntewith eorrespondingl tapered or incliner.. surfaces on the turn plate supporting bar.. ln tlte present instance the we: ges are. enf larged toward their u pct: ends and thev-cooperate with a pair o. revetselv tapered surfaces V45 and tti on the cross piece andthe wedges may be adjusted verticaliy and indes pcndently nf one another for the purpose of shifting the turn plate forwardly. and rearwardl)v b v means fof bolts 4T and 4S which -are attached tothe respective wedges and 'extend downwardl) into a recess-t9 in'the hous- 'respective ,bolts and servingr as a means for Y adjusting the wedges and l-w'sing them in ad- A f justed position.
Vertical adjustment of the turn plate may be eifel-'ted by means of a pairA of wedges 53 1.15 and 54 which restl beneath the ends of the cross bnr. the lower sides of the wedges engaging substantially square surfaces of the housing, while the upper inclined surfaces 55 ioses, but it leaves the umler side of the` housing unobstructed so that a juice pan t -may be placed between the-housings and i under the rolls. and pro-vided with :t pair of laterally extending .si-outs '.25 and '.ti which 60 extend immediately beneath tbe housings and ctnnmunicate with gutters T and 1N which serve to conduct the iuice expressed from the caluito an)v suitable point.

Tightening of tht` wedges 4l 'and 125t -t'l has a tendone) to draw the cross bar do\\'n\\"ardl v into engagement. with the wedges 53 and 5 3! and endwise movement of the cross bar is prevented b v the inclined surfaces on its under side woich engage the .means of wedges 29 andSO, those edges of i bolts Bland 34 in the present instance which '75 v ing. the tuus 50 and 5t cooperating with the 110 crushed cane as it l l i l l `to avoid undue friction While stripping the 'of the wedges 41 and 42.
i su'jnitportin'lWedges, the 'oppositely tapered su aces of the up `er sides o the wedges presenting inclined p anes which will resist end thrust of the bar for the. reason that the lat-l ter cannot rise because of the locking action In mills constructed in accordance with the present invention,
the front and rear rolls may be placed relatively close to one another for the reason that there are no bolts or other obstruct-ions which extend through the housin between the turn plate supporting bar an vjournals of the rolls, and this is advantageous. as it enables a turn plate to be employed that has .a relatively small surface which enga es the asses between t e rolls, the friction thus re nced enabling the mill to operate more economically.
A mill constructed in accordance with the present invention is not liable to breakage under stress of the rolls for the reason that the strains are resisted by tension members which extend indirect-ions parallel to the directions in which the strains' act and theyl wholly surround the journals of the rolls so that the latter cannot possibly spread, .and
the relatively small size of the sections comprising the housing reduces the weight of the parts to such an extent that they may be made and transported cheaply and readily assembled,` Moreover, the reinforced -cornstruction ofV the housing enables the front and rear rolls to be placed as close as may be desired, and consequently the width of the turn plate ma',v be considerably reduced so as material from the frontroll and transferring it to the rear roll. l
The improved mounting for the pressure regulating ram enables the'actual pressure Ibetween the rolls to be determined with' certainty, and it is in a conveniently accessible position, while the mounting for the turn late enables the latter to be adjusted with acility, and it is positively locked from movement.
