To all 'whom 'it may concern: l

Be it known that I, HERBERT J. FRINK, a citizen of the United States, `residing in the city of Holyoke, county of Hampden, and State'of Massachusetts, have invented certain-new and useful Improvements in Ad' justable Bearing-Boxes, of which thefollowing is a specification.

This invention relates to bearings or journal boxes and more particularly to boxes for 'supporting the calender rolls in a paper calendering machine. E.

An object of the invention is to provlde a journal box construction, especially adapted for use in paper calendering machines, embodying in combination an eccentric sleeve or bushing in ,which the journal of thefroll is' adapted torotate and a journall box arranged to support the sleeve having a cored chamber through which water or other cooling medium is adapted to circulate, whereby the bushing and thus the bearing surfaces may be kept from overheating. In this construction a removable cap is provided on the end of the journal box by means of which access may be had to the bushing for adjustment without disturbing the journal box `and its cored chamber.

A further object is to provide a paper calendering machine having its rolls mounted in journal boxesone set on each side of the machine, constructed as stated, which boxes in each vertical set are adjustable in vertical ways of the frame. The latter adjustment is arranged to co erate with the bushing adjustment to line t e axes of the rolls accurately in the two dimensions as desired. The cored chambers of the journal boxes arranged in the vertical ways on each side of the machine are connected bfy-,fiexible hose so that water can circulate rom one journal box to another.

Another object of the invention is to provide a journal box of the class described which is adapted to support the shaft or journal of a calender roll in an adjustable manner.

Another object is to provide a journal box wherein the shaft is shiftable horizontally for the purpose of alining the axis thereof with the axes of adjacent shafts. j

Another object is to provide in connection with an adjustable bearing of the class described special lubricating devices to cooperate therewith.

A further object is to provide in a journal f Specification of Letters Patent.

box for a'calender roll an adjustablefdevice to receive the end thrust of the roll.

Other objects will appear in the detailed description to follow. a

My improved. journal box is particularly applicable tothe paper calendering machine.

vertical movement for the adjustment of the 'I axes, of. the rolls in various horizontal planes. The ordinary calender provides no means forshifting the roll horizontally for the purpose of alining the axis of the roll in a'vertical plane with the axes of adjacent rolls. It is common knowledge inthe paper calendering art that, unless. the axes of the calender rolls are properly alined so that they all lieinthe same vertical plane, the paper passing through the machine between these rollswill be wrinkled or torn. A. machine originally built with the rolls in proper adjustment may after being -used -some time .get out of adjustment. I seek .to provide by my invention, suitable means for adjustingin a most convenient manner, the

journal ofthe roll ina horizontal direction,

whereby I `may so adjust each roll that the axes of all the rolls will lie in one vertical plane. l i

In the accompanying drawings wherein I have shown a preferred embodiment of my j invention--Figure 1 is a plan view of my improvedl journal box; F1g.2 is an elevational` view partly in section, taken on the ti'on of the arrows;`Fig. Sis a 4longitudinal sectional elevation taken onlthe median` line ofFig. 1; Fig. t isa perspective view of the eccentric bushing; and Fig. 5 is a diagrammatic view 4illustrative of the' :purpose and application of my invention. Flg. 6 is a diagrammatlc v1ew showing the manner of.

Each flange 2 is provided with finished sur-` Lad faces 2 and 22 at right angles to one another,.whieh abut the ways of the calender indicated -by dotted lines at 31 in Fig.l 1. Each flange 8 is provided with a finished surface 8 for the same purpose as the surtace 2. Removable flanges et, securedyto Iflanges 3 by bolts 5, abut the ways of the calender on the Asurface d; and restrain the box in place therein. i

, lll/*ithin the body portion 1 is mounted a bushing 8 ibored eccentrically to receivethe journal 7 oit the calender roll` .6. An enlargedportion 8 ot the bushing 8 entends beyond the body 1 as clearly shown in Fig. 3. 1n this portion 8 are provided at suitable intervals holes 11, which are adapted to receive a Spanner wrench, whereby the bushing 8 may be turned. llhe bushing 8 is also.

formed with a circumferential groove 13 which is adapted to receive the ends ot a pair ot set screws 12. rEhe latter are suitably mounted in the body 1 as shown in Figs. 1 and 2 and serve to clamp the bushing 8 in position. The bushing 8 is furthermore provided with two series or" slotted holes 9 adapted to allow oil from holes 10 in the body to pass to the journal 7. These holes 9 are so arranged that one of each series is always in communication with a hole 10, no matter what angular position the bushing 8 may assume.

The outer end of the journal box is closed l by a cap 2.0 removably secured to the body 1 by cap screws 21. Mounted in a circular recess 26 in the end wall Yot the cap 2O and axially movable therein by the adjusting screw 22 is a plate 23.

in the cap 20 and loosely' engages with a hole in theplate 23. The plate 23 bears against the end face 25 of the journal 7 and forms van adjustable means for receiving the end thrust of the journal 7. The plate is provided with a vertical oil groove 27 ex'- tending from the upper edge to the center ot the plate. The groove 27 is located in un'.- der the oil hole 19 in the cap 2O and is l adapted to convey oil therefrom 4to the end face 25 of the journal Y.

The rear portion of the body is termed with an inturned flange 28 which forms a circumferential channel 29. rllhe latter is adapted to receive the oil which emerges trom oil grooves 32j. The oil leaves the body I,

1 by means of passage 18, communicating with a pocket 30 in the channel 29 at the bottom of the journalbox', as clearly shown in Fig. 3. The oil flowin from opening 17 of passage 18 is directe by any suitable means to the oil holes 10 ot the journal box immediately below, as by means of a short pipe or hose, not shown, it being understood that the journal boxes are arranged as shown in Fig. 6.

lt it is kept in mind that the journal lriphery of the bushing.

rllhe latter is lheld r against rotation by a pin 2d which is fixed.

ybones in each set are adjustable vertically tained itA thejournals can be properly oiled if and kept from overheating.. The oiling. system especially adapted for the purpose has been described. 'llhe overheating is prevented by providing in each journal bon cored space 16 nearly surrounding the pe'- vil/vater can tlow from one opening, as 1i, (see Figs. 1 and 2) to this space ltfand trom the other opening 15, thus circulating around the bushing to keep the latter cool. Referring to .8, the exit opening 15 of one journal boa is preferably connected to the inlet opening 111 et the journal box just below throughout the set, by flexible hose 5G and a pump is used to torce the water Jfrom the last exit opening 15 to the inlet opening of the top journal, Thus a constant iiow et water is kept in circulation to insure 'the cooling all the bearing surfaces in the journals.

'llhe general operation oil my device will be clearly understood with reference to Fig. 5. rllhis ligure shows diagrainmatically two rolls a and l), whose 'axes c and ci, respectively, are out oili alinem'ent. Since these aires c and d do not lie in the same vertical plane, paper passing through the rolls t and b will be torn or wrinkled. By my adjustable journal box, hereiribefcre disclosed, l may conveniently aline either roll 0:, or l) 'with the other so that their axes c and d, re-

bushing 8. lllhis operation will, by reason 'i l of the eccentric bore ot the bushing throw the shaft in a horizontal direction whereby proper alinement may be secured. llt is to be noted particularly that although operation of shifting the ececntric throws the shatt horizontally, it is also moved vertically to some degree. Since, however, the body 1 is freely slidable in the ways 31 of the calender, the rolls drop into Contact and nullity this vertical movement. the adjustment of any of the journals, the cooling system is not interfered with, but remains in constant use. rlihus, l have provided ecient means tor alining the rolls et a paper calendering machine at any desired time so that the axes of the rolls will all lie in a common vertical plane and the journal will not overheat.

lt is recognized that many modifications' may be made in the structure of my invention which is more truly defined in the appended claims than in the -foregoing specifici description..
