Application filed May 15,

and particul thereror. T3-.e invention has particular relation to tln tyne ot printin` press in which the inlring rollers travel over an inlring platen or rotary inlring plate and down across the type Jrorm.

r1Ehe object of the invention is to provide improved inlrina mechanism suoli presses in which the composition inlring' rollers, or varyin3 on account oi: shrinirage or eX- pansion, are nnoable or beingadjusted independently he trucks the rollers and the bearers upon which they travel, thereby giving the proper relation or' the varying sizes of composition rollers to the ing' distribnting` roller which drives the composition rollers.

i 'i'urther object ot the invention is to ynovide nner-eyed inlringg; mechanism in which the inlring rollers are rotated by the Vibrator roller which in turn is driven from the truc-lr but in which mechanism i may be of Varying sizes but a ss readily adjustable V1 .L with relation o the -lnng plate and type without int ntlN said driving arrangement.

@n either side of said inlzing plate are lo- 'oated the extension bearers 2, which are illustrated as angle members with one flange horizontal and serving as a track or support along` which the truclr rollers o1p4 the inlring` mechanism travel. @ne bearer is provided with a rack 3 for causing rotation oi the vibrator roller, as will later appear. rlhe inking` rollers shown are three in number, to wit, two composition rollers el, both of which are designed to travel in contact with the surfaces of tie inlring plate and type, and a third or vibrator roller 5, usually of metal, which lies above and contacts with both of the composition rollers e.

Vibrator roller 5 lies aboye a cross sha-ict member consisting` of a sleeve 6 4l) surrounding the inner ends or two shaft sec- 'tions 7, which in turn are pinned to inner and outer truck iframe members 8, 9, and eX- tend outwardly beyond the saine. llt their ends these shaft sections receive the upper ends oi2 links or bars l0, which extend downwardly on opposite sides of the press and are connected to suitable operating,r mechanism, not shown, to traverse the trucks and inlr'iic; rollers along` the bearers across the inlring plate and type and baelr again, as is usual. rl`hese linlrs or bars are of well known construction embodyrng` yielding tension means, not shown, to hold the trucks and rollers down upon the bearers with yielding pressure, as is usual.

ln each or' the truclr members are located two non-rotatable sleeves 1l, on one or which is journalled a gear l2 meshing with the rack 3 before referred to. @n each of said sleeves is also located plain faced roller 13 provided with roller bearings il. rlhese Ytour rollers arranged in pairs, two in alignment with each other on each side ot the inlring` plate, and each oiE which pairs of rollers travels along one oi the extension bearers Q. These rollers and the truc rs in which they are journalled therefore serve as t ie supports for the inlring mechanism.

Each of the composition rollers fr is carried by a sleeve or buShing` l5, two oi which surround each one o a pair of cross shafts l5, there beine one such shaft ior each pair of truck rollers, rthe two shafts 16 extend outwardly through the truck li ames and at their ends are provi ded with blocks l? held in place at one end oit the. shalt by a pin 18 and at the other by the head of` a screw lf threaded into the shai't end.

, tion het w'een Referring to Figs. 2 and 3, it will be .observed that the blocks 17 are of elongated form, being provided in their lower ends with elongated slots 2O to receive clamping screws 21 threaded into -depending ears 22 on the truck frames. At their upper ends theL blocks are provided with T slots 23 curved lengthwise around the centers of the openings 20, said slots being designed to receive the heads 24 on the lower ends of set screw blocks is a set screw 26, the inner ones of which are inclined as shown in Fig. 4, to enable them to be more readily manipulated.

Shafts 16 where they pass through the openings in the sleeves 11, are smaller in diameter` than said sleeves. qence it is possible vto adjust each shaft in any direction, either vertically or horizontally, or both, and without disturbing the positions of the sleeves 11. The vertical adjustment enables the composition rollers to be adjusted into proper contacting relation with the inlring plate and type, and the horizontal adjustment enables the contacting relation with the vibrator roller always to be preserved. For example, set screws 21 may be loosened and by manipulating the two set screws 26 the blocks 17 may be shifted to the right or left. At the same time the screw 25 may be actuated for movingl saidblocks up or down. After proper adjustment the screws 21 are again clamped. out altering the relation between the truck rollers 13 and the bearers on which they travel or the relation betweenv the gear 12 and the rack with which it engages. The construction is particularly advantageous because it enables proper adjustment to be made to compensate for any variations in the sizes of the composition rollers, either as said rollers are replaced by new ones or `as they become compacted or shrink in use.

The adjustment therefore enables the composition rollers to be made to travel in proper contact with the inlring surface and also with the type. rlhis construction is therefore more'satisfactory than one whereiii the inlring plate itself is adjusted relative to the rollers, which adjustment when does not-improve the contacting relat" the inlring rollers and type, or other constructions in which the composition rollers are adjusted bodily `with the Vtruclr rollers and driving gearv12, which disturbs the drive to the rollers.

rEhe gear 12 meshes with a pinion 27 upon Athe shaft 28 of the vibrator roller 5, which s constructed and is actuated in the manner common in such mechanisms. l/Vithout describi: suoli mechanism in detail it is only necessary to state that on one side of the press, as at the left in Fig. 5, the shalt of the vibrator roller telescopes and slides rit each side of each of said As a conse- The adjustment is effected wit`n.

Lacasse` in the driving sleeve 29V while at the other side said shaft is providediwith a threaded portion 30 engaging with a nut 31 so that rotation of said vibrator roller by the gearing' before described causes it to travel longitudinally back and forth from side to side of the machine and thoroughly distribute the ink upon the composition rollers.
