INKING ROLLER FOR PRINTING-PRESSES.

To all whom it may-concern.

, Be it known that I, Jenn H. Scnussmsn,

a citizen of the United States, and resident of Chicago, in theccountyof Cook and'State of Illinois, have invented certain new-Wand useful Improvements in Liking-Rollers for Printin '-Presses, of which the fOllOWlIlg 1s a specification. a My inventlon relates to'improvements 1n inking rollers for printing presses of the same kind as those described in my co-pending application Serial;No.L18 5,888-, filed August-13, 1917, and has for its particular object'the provision of: adjustable hearings surface and inking disk. 1

qulred in an ordinary bearing. 1

A further objectof myinvention is to provide a simple. built-up bearing a which may be. readily assembled. or taken apart so. as to replace any worn orzdefective part.

r A still further object is the provision of a bearingwhich maybe adjusted in such .manner that the inking rollers will contact withthe printing surfacev only as the rollers travel over the printlng surface in one threetion if it is so desired."

My invention will be further and better understood by referenceto the accompanying drawings, in whicha i Figure 1 is an elevation showingathe ends of the bearlngs carried by oppositely disposed hook members; a Fig. 2 is a sectional view through one of thebearings and one of the frictional rollers; Fig. Sis a sectional-viewon line '33 of Fig.2

head 1O at outward end, the said head .member :having oppositely disposed hooks atrack 15 onthe frame 15 and transmitting motion to the inking roller 16, (Fig. 2), thus insuring the rotation ofthe inking roller. as the traveling member 10 movesupward and downward. The inking roller has. a reduced .or shaft'portion 17, over the end of which is smou'nted anyeccentrlc cyllndrlcal cap mem ,ber 1 8ha v1ng a squared end 19 m order that a wrench may be fitted thereon-so that the turned to any desired position. The eccentric member 18 is lfitted into the hooked

portions

11 and 12 of the head 10, andis secured in'saidxhooked portions bymean's of a nut 20 having threaded engagement with the outside end of said "eccentric, and. which when screwed up tightly holds the bearing in position, the inside of the hook abutting against a collar 21 which 1 is fitted over the eccentric and which indturn abuts against, an annular shoulder 2l on the eccentric 18. Mounted is. a built-up frictional roller 13, the said Z-frictional roller having an outside portion 22 composed of rubber or other resilient for. the roller as it travels up and down on the trackilo. The built-up frictional roller iscomposed of a member:23havingan opening therein to fit over the cylindrical eccentric 18, and which fits snugly against an drical eccentric 18. F orminga part of said "frictional roller13 isa ring or annular portion 25 which forms a seat for the resilient portion 22 and also forms a bearing surface for the ball bearings 26' interposed between centric 18. The shoulder portion 28 of the 24: formed upon the cylin on the inner :end of the cylindrical eccentric member 23 forms a vertical bearing and retaining means for another row of ball bearings 30. 7 v

A washer 31 is inserted between the rows of

ball bearings

26 and 30 and serves to hold each of these rows of ball bearings apart and also an inside bearing surface. Forming the H inside portion of the frictional roller 13 is a member '32 which is connected with the member 23 by means of bolts 33 which pass through the portion 22, said bolts having s their heads countersunk in the member 23 and having threaded engagement with the .member 32; Fitted to the shaft portionl? of the inking roller 16 is an annular member 1 34:, the said member 34 having grooves 35 extending transversely across its inside face.

Pins

36, 36 are inserted into the verticalpor--- tion 27 of the member 25 and protrude into the transverse grooves 35 in the member 3 1, so that as the frictional roller revolves, motion is transmitted to the member 34: and

thence to'the inking roll. Or'if it is desired,

lugs may be formed on the member 25 so as to fit into the outside portion ofthe transverse groovep35' in the member 34:. A

key 37 is attached to the shaft portion 17 of the inking roller 16, and fits into arecess 38 of the member 31. The outside diameter of the member 34 is less than the inside diameter of the member 25, and therefore fits

hooks

11 and 12 are clamps a0, 40, the said clamps being held in position by means of lug screws 41, ll, screwed tightly against the surface of the

hook members

11 and 12.

Through the thick portion of the eccentric 18 a hole 42 is drilled, a corresponding hole 42 being drilled through the member 2 1 and a pin inserted through the member 21, the

amember 21 being therebykeyed to the cocentric so as to prevent rotation upon said eccentric member 18'.

In adjusting the inking roller 16, the nut .2O is loosened and a wrench applied to the squat-a portion 1910f the eccentric 18, when said eccentric can be turned to any desired position, 'andithe printing roller 16 secured to any desired adjustment with relation to the printing surface or inking disk. The nut 20 will thereupon be tightened and the clips i0, 40 adjusted to such; position on the hooks'll and 12 thatone pair of the

shoulders

39, 39 of the

members

21, 21 will abut against the saidclips. It will be understood, of course, that the inking rollers are zreciprocated by means of a pair of travel- 7. "Iclaimz ing members, only one of which, the mem .ber 10, isjshown, and are rotated through the friction rollers 13 and 1a coming in contact with the track on the frame of the press, the'friction roller 23 turning upon the ball bearings mounted upon the eccentric portion and in turn transmitting its motion to the member 34 through the

pins

36, 36 fitted into the groove portion ofthe member 34, .which iskeyed' to the shaft portion 17 of the inking, roller 16. Therefore, the reciprocation of the armslO and the contact inking rollers 16, thus securing an even distribution of 1111: upon the mklngroller and also upon the printing surface. r

If it is desired, he nuts 20- maynot be screwed tightly against. the hook members 11, when the eccentric portion 13 will reverse itself at the extreme points of its path of movement, and the eccentric 1nember'18 "will make approximately a one-half revolution, carrying-with itthe member 21raround to the point;where one'of the pair of shoulders 39 will contact with the clip 10, and

of the frictional rollers 13 and 1 1 rotate the 7 :the printing 'roller .16 will 1 thereby be" j thrown out of contact with the prin-tinglsurface in one direction of itsmovement as it passes over the printing surfaces. 1 The clips 10, 4:0,niay be positioned on the

hooks

11 and 12 atany desired'place, thus insur ing proper'adjus'tment of the inking roller -with relation to the printing surface at all times. 7 g
