Specioationof Letters atent. f
`Tolafll whom it concern.' Y vBe it .knownfthat l, ALBnR'rT. KELLER, a
y citizen-vof. the United States, residing at Pittsburg, .in 'the-county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements `in RollingfMills, of Awhich the following'isa specification,` reference being-had therein to the accompanyingdrawings.
1 port the adjustable roll anddrivingspindle; coupledtthereto thateaclifof the roll bearingsl and adjusting screws is subjected 'to thesame amount of pressure, thus avoiding rolls supported as heretofore,constantwatch-' Oneiohject `of th-'s invention is to -so supunequal wear. The `gage of the roll.pass vis thereby preserved, resulting `in the lproduction of plates of uniform thickness.
`other plates, skelp, etc., is objectionable, usually resulting 1n their rejection, hencethe necessity forextrelne accuracy.` With the ing and frequent adjustmentv and renewal of the bearings is necessary owing to unequal wearing of the latter.
A further object is toprovide improved` `means for connecting "the roll-supporting means with the bearings. i 1
. vAnother,'object'A ist@ provide a roll -supportinganiechanisnr which may be utilized as an elevator'foriraising vand lowering the rolls in` the housings 'when' inserting'and removing them. i
. An embodiment ofl the invention is ',illustrated in theaccompanying drawivngs ap- .plied `to a two-high mill, Figure 1 beinU with the improvements.
aside elevation, partly broken. awayand partly in section, of such Aa mill equipped cross-sectional view 'o'i onev of the housings and roll hearings thereof, the plane` of sec tion being indicated on Fig. Al by the line' 2 2, and F1g..3 is a .similar view taken on line 3 3 of thesan'ie figure. Fig. 4 is a sectional detail view taken on line 4 4 of Fig. 1. Fig. 5 is a detail view of one of the suspending hars. Fig'. 6 is a side elevation illustrating thev improved mechanism in use for changing the rolls.
Referring to :the drawings, 21 designates the roll-housings ,which may be of the'usual or any preferred construction, and 3 is the bridge or upper structure between and connecting the upper portionsof the housings.
4 is the-lbwer roll and 5 the upperroll, 'bearings 6 of the latter engaging adjusting Very.. slight .variation `in the thickness of boiler and Fig. 2 is a vertical.
u orm -wlieels 8 `driven by wormshaft 9 which may vextend from an electric motor l0. No novelty' isicla'imed' for4 the screw adjusting mechanism,- which may be 'arranged as here shown Aor in any otherpreferred manner.
-Mounted on bridge 3:'is cylinder 11' of aI .fhydraulic lift or ram,and carried'by pluri' er .12 thereof is cross-head 13` from which ef screws 7/which are-raised .and lowered-by sfo pend hangersV 14, the hangers being held in perpen icular position by oruide-lugs 3.
Preferably pivotedat 14, yto Tiangersl/l isA the roll-support which may consist of two horizontal parallelhars 15, extending longi- `tudinall'y of the mill through ",the housingwindows, and suspended from'this support are bottom hearings. 16' ofthe upper roll.
While the connection bet-w een the support and hearings may befmade in any suitable manne/,Ll prefer to Vemploy rods '17, which extend vertically withinthe housings, being hooked at their upper ends to overhang the lbars and extending throughA bearings `and `16 with keysfl beneath the latter.
In Fig. l is illustratedaportion of the' driving pinion mechanism 1S and housing 19 therefor, with drivingspindle 20.fextending to' lower roll 4, and .a similar spindleZI for the upper roll, all Abeingof usual Vand well known construction. Spindle21 is acli'votally l carriedA by the` two longitudinal arsV 23.
justablysupported 'by bearing 22 These bars are sustained at one end by links 24 :depending from pinion-housing l 1 9 and at theirlopposite .ends are connected-by links 25 with t e extremities of ,bars 15. Thusthe supporting mechanism, which is comin'on to the roll and the driving 'spindle-,is separately- Vconnected thereto, and with the ,roll `relieved y vrof, the weight ofthe sprindletlle load on both l.bearings of the'lroll 'isgthe sanieyresulting in equal wear. Thehydraulicfliftis ,located at one side of the center of bridge 3 in order to balance the load thereon andto 4equalize the pressures on the adjusting screws.

' To facilitate' the operation f inserting or changing rolls the improvedmechanism may be utilized as an elevator, asi indicated in.
Fig. 6. At -such time the driving spindles are disconnected and the 'roll-wabblers are.
embraced by chains 26 depending from bars 15. To prevent bars 15 from tilting, lift vconnection 14 beingat one side of the center,
the 'lower extremities yof hangers 14 are formed with lateral extensions 27 which A ing'lifting' mec -form a passage for bolt 28 which is-projeeted 4 therethrough and through'apertures"15 in thus be quieklyand conveniently raised'or with 'which the'roll bearings and spindle have porting member.'
