INKING MECHANISM FOR PRINTING MACHINERY.

Application filed October 21, 1925. Serial No. 63,973.

My invention relates to inking mechanism for printing machinery, and is exemplified as employed-in connection with a rotary form cylinder. The term form cylinder includes any cylinder having thereon printing letters. lines or configurations, whether on the cylinder itself, or on type, cuts or plates attached to the cylinder.

It is the object of my invention to provide new and improved means whereby even distribution of the ink is obtained, so as to effect a uniform and even application of ink to the printing surfaces; further, to provide novel means for adjusting the form rollers with relation to the printing form; further, to provide novel means whereby the form rollers are simultaneously moved out of contact with the printing form while the ink distributing contact of said form rollers is maintained; further, to provide novel means for adjusting the form rollers with relation to a coacting inking roller; further, to provide means for moving the form rollers in directions toward and from the printing form and in directions toward and from their ink supplying rollers in sequence; fprther, to provide novel means whereby the form rollers are adjusted toward and from the printing form to compensate for variations in diameters of the form rollers during operation; further, to provide novel means whereby a composition roller is adjusted toward and from a coacting inking roller; further, to provide novel means whereby a composition roller is adjusted laterally about an inking roller for adjusting contact relation with a neighboring part; further, to provide novel means for adjusting the contact relations between distributing rollers and a reciprocating roller coacting therewith whereby the pressures of contact between the same are adjusted; further, to provide novel means whereby the form rollers and the distributing rollers are connected for combined movements; and,

further, to provide means whereby the form rollers are released from contact with the printing form, and the distributing rollers and form rollers have contact with their respective reciprocating rollers, for distributing ink over the cylindrical surfaces of all of the rollers without transference of the same to the form cylinder.

It is the object of my invention further, to provide novel means whereby all the printing rollers are freed from contact with each other and with the printing form, and preferably spaced apart, for ready access to all parts of -the printing rollers and for ready turning of the same out of contact whereby to readily clean all the inking surfaces thereof; and, further, to position all the composition rollers out of contact when not in use in order to maintain their cylindrical shapes.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

For convenient reference it may be stated that Figs. 1, 5, 6 and 9 are views taken at the gear side of the printing press; that Fig. 8 is a view of the gear side of the printing press look-ing from the feed side f the printing press; and that Figs. 2, 3, l, i' and 10 to 26 inclusive are views of the feed side of the printing press or taken in directions viewed from the feed side of the printing press.

It may he further stated that a fil'i-Iflf many of the parts at the feed side of the printing press are duplicated at the gear side of the printing press. The following description of the present exemplification will be made primarily from the feed side of the printing press, and where similar parts are located at the gear side of the printing press, such similar parts will be designated by similar but primed reference numerals.

The frame of the machine is represented its length with relation to the fountain roller, by screws 38 in usual manner, for adjusting the thickness of the film of ink carried by the latter. (See Figs. 1 and 3.)

A feed roller 41 is mounted in the frame,

as in bearings 42, 43, at its respective ends.- (See Figs. 3, 9 and 10.) The bearing 43 is on a bracket 44 fixed to the frame. The feed roller is adjustable for parallelism between it and the fountain roller, as by mounting its bearing 42 on the slide 45, adjustable laterally on a guideway 46 fixed to the frame. A bolt 47 is threaded into the slide, and is received through registering holes 48 in the guideway, the frame and anouter guide plate 49, the latter being fixed to the frame by a bolt 50.

The bolt 47 is also received through a hole 51 in a slide 52 which has a threaded bearing 53 in which a bolt 54 is received, the latter being journaled in bearin lugs 55, on the guide plate 49, and held in endwise relation in said bearings between the head of said bolt at one end and a collar 56 fixed to said bolt atits other end.

Rotation of the bolt 54 causes movement of the slide 52, and consequently of the hearing 42, lengthwise of the bolt, in one direction or the other according to the direction of rotation of said bolt 54. When the adjustment has been made, the parts are clamped together by drawing up the bolt 47. (See Figs. 2 and 10.)

A ductor roll 61 is movable laterally between the fountain roller and the feed roller for transferring sections of the film of ink from the fountain roller to the feed roller. The section of film thus transferred at each oscillation of the ductor roller extends over a considerable portion of the periphery of the ductor roller, so as to convey a film of ink to the feed roller rather than a strip of ink. The shaft of the ductor roller is suitably mounted. as on arms 62, at its respective ends, adjustably fixed to a rockshaft 63. in usual manner. The rock-shaft is suitably journaled in hearings in the frame, and has an operating arm 64 fixed thereto, operated for instance by a link 65, having articulating connection 66, with said arm, the link being opei'ated from a suitable part of the pressv (Fee Figs. 1 and 3.)

A reciprocatin roller 71 is provided with axles 72, 72', at t: respective ends. the axles being journaled sleeves73, 73', fixed to the frame. (See Figs. 4 and 5.)

Ice

A pair of sets of distributing rollers 74, 75, 76, and 77, 78 and 79, are arranged respectively above and below the reciprocating roller. The distributing rollers are respectively provided with axles 81 and 81 at their respective ends, journaled in bearings 82 and 82 at the respective sides of the press. Each of the bearings comprises a releasable cap 83. for ready removal of the roller, the cap being pivoted on a pintle 84, and clamped in place b a bolt 85 threaded in the base of the cap. (See Fig. 11.) Each of these distributing rollers makes contact with the reciprocating roller 71 for mutually distributing ink over the same. The distributing rollers 74, 77, also normally make contact with the feed roller 41 for receiving the film of ink from the latter and conveying it to the reciprocating roller. (See Figs. 1, 2, 3 and 11.)

The reciprocating roller 71 is exemplified as a roller having a large diameter. A pair of reciprocating rollers 87, 88, respectively coact with the end ones of the respective sets of distributing rollers.

These reciprocating rollers are respectively provided with axles 89, 89', 90, 90, at their respective ends, which axles respectively rotate in sleeves 91, 91x92, 92', respectively fixed to the frame of the machine. (See Figs. 1, 2, 6, 7 and 8.)

Endwise reciprocation is imparted to the reciprocating rollers 71', 87, 88. as by providing the axle 72 with a spool 93 fixed thereto, and .providing the respective axles 89, 90, with spools 94, 95, fixed thereto respectively.

A rocker frame 96 is provided with bearings 97 rockable on a stub shaft 98 in a bearing 99 extending from the spider 32. (See Figs. 2, 4 and 7.) The rockable frame is provided with arms 101, 102, 103. respectively provided with rollers 104, 105. 106, received in the annular grooves of the spools 93, 94. 95. The rocker-frame is arranged to be rocked on said stub shaft, as by provid ing it with an arm 107, which has an articulation 108 with a link 109. suitably operated by an operating part of the press, for imparting reciprocating motions to the rockerframe. The arms on the rocker-frame are arranged to reciprocate the reciprocating rollers 71. and 87. 88, in opposite directions. The axles of said reciprocating rollers rotale and move axia'lly in their respective sleeves.

The distributing rollers 76. 79. of the respectivg sets of distributing rollers. coact with the respective reciprocating rollers 87, 88. for conveying the distributed ink from the respective distributing rollers to said respective reciprocating rollers 87 88. which are in spaced apart relation. for respectively serving a pair of form rollers 111. 112. and a pair of form rollers 113, 114. These pairs of form rollers are the end rollers 0f the respective sets of rollers, which are served from the respective sides of the feed roller.

The form rollers are arranged to ink the printing surface on the printing f rm. which is exemplified as, a form cylinder 115, and shown as a plate cylinder, having curved printing plates in; suitably secured thereto in well-known manner.

The form cylinder is suitably mounted and rotated in the frame, the means for mounting and rotating the same not. being more particularly shown or described, be cause any well known means for accomplishing the purpose may be employed.

It will thus be seen that the ink received in a film from the fountain roller. is conveyed to a feed roller and from the latter to opposite sets of distributing rollers, between which a reciprocating roller rotates and reciprocates, the distributed ink being conveyed to spaced apart smaller reciprocat ing rollers. which respectively serve separate pairs of form rollers, as will be noticed from Fig. 3. A system of rollers is thus provided which has a maximum number ol contacts with each other within av small compass, there being twelve points of reciprocating contact between the three reciprocating rollers and the distributing rollers and form rollers respectively, making twelve points of reciprocating contact between thirteeen rollers for effective and even distribution of the ink when it reaches the printing surface on the form cylinder.

The ductor roller, the distributing rollers and the form rollers, are in practice made of suitable metal tubes surrounded by suitable composition for the rollers, the rest of the rollers being preferably metal rollers.

Means are also provided for moving all of the distributing rollers toward and from the reciprocating roller between the same and toward and from the other rollers cooperating therewith. (See Figs. 4. 5, 11, 12. 13 and 14.) Thus the rollers 74. 75. 76, arc mounted in adjustable relation at their respcctive ends on supporting plates 121, 121' at the respective sides of the frame of the press, and the distributing rollers 77, 7 79. are mounted in adjustable relation at their respective ends on supporting plates 12;. 122. The supporting plates 121, 122, are provided respectively with guidcways 123. 124. in whichguidcs 125. 126, cxtcnding from the frame, are received, for guiding said supporting plates.

The supporting plate 121 is provided with a loop 128, and the supporting plate 122 is provided with a loop 129.

A cam sleeve 131 is received about the sleeve 73 fixed to the frame, and has thereon cams 132, 133. The supporting plate 121 and its loop has guides 134, 135, secured thereto at the respective sides of said cam sleeve. The supporting plate 122 and its Ill) loop has guides 136, 137, secured thereto at the respective sides of the cam sleeve.

Cam shoes 138, 139, are rrceived between the cam 132 and the respective guides 134, 135, and cam shoes 140, 141, are received between the cam 133 and the respective guides 136, 137. The cams, and the shoes and guides co-operating therewith, are so arranged, that when the cam sleeve is rotatcd, the supporting plates with the distributing rollers supported thereby, are moved either toward the reciprocating roller 71 or away from said reciprocating roller at both ends by mechanism to be presently described.

Thus a shaft 130 is journaled in a hearing 142 in the bearing spider 32 at the feed side of the press, and is provided with a inion 143 which meshes with a segment gear 144 on the cam sleeve. (See F igs.2 and 4.)

This shaft is provided With a hand-Wheel 145 for operating the same. This shaft also carries a pinion 146, which meshes with a pinion 147, on a stub shaft 148, fixed in the T bearing spider 32. The pinion 147 meshes with a segment gear 149, fixed to a shaft 150, journaled in a sleeve 151, and in bearings 152 and 152 in the spiders 32 and 32. The sleeve is journaled in bearings 153, 153', in the frame, at the respective sides of the press. (See Figs. 4 and 5.)

A segment gear 149 is fixed to the other end of said shaft and meshes with a pinion 147 on a stub shaft 148 fixed to the hearing spider 32. This pinion meshes with a pinion 146 on a stub shaft 130 in a bearing .142 in said bearing spider 32, the lastnamed pinion being elongated and also meshing with a segment gear 144 on the cam sleeve 131 at the other side of the printing press.

Means are further provided for imparting lateral adjustments to the distributing rollers in directions about the outer periphery of the reciprocating roller 71, these adjustments being oi the distributing rollers 74 and 75, and If? and 78, toward and from the fe d roller, and of the distributing rollers 76 and 79 toward and from the respective reciprocating rollers 87, 88, and means are further provided for-adjusting the distributin; rollers toward and from the axis of the rcri nocating roller with which they coact.

"fir-us the supporting plate 121' is provided h an armate slot 1.75, in which an armrib 156 on a slide 157 is received. (See igs. 11 and 13.1 A bolt 158 is journaled in bushing 159 in a bearing 160 on the supporting plate 121. It has a nut 161 fixed thereto outside said bushing. The bolt is recei ed through a cam slot 162 in the slide 153., and has threaded connection with a cam block 163 in said cam slot. The outer end of the bolt has a washer 164 across the outer end of said cam slot, a clamp nut 165 being threaded to said bolt and arranged to clamp said washer, said slide, said supporting plate and said bushing between said nut and the end limit nut 161.

The cam slot is at an an le to the plane of the slide 157, so that the 1de will be moved laterally on its arcuat-e guide by axial movement of the cam block by means of the bolt, whereby the distributing roller 76, mounted on said slide, is moved laterall toward or away from the reciprocating rol er 87. (See Figs. 3, 11, 12, 13 and 14.)

Similar means designated by similar reference numerals are employed to laterally adjust a slide 167, which supports the distributingroller 79, and similar means designated by similar reference numerals, are employed to adjust slides 168,-169, along the arcuate guides 155, the distributing rollers 74, 75, and 77, 78, being mounted on said respective slides 168, 169. (See Figs. 11, 12, 13 and 14.)

The means for adjusting the distributing rollers toward and from the reciprocating roller are similar for each of said distributing rollers, a description of one suflicing for all. The slides 157, 167, 168, 169 are pro- .vided with guideways 171, on'each of which a slide 172 is adjustable, the slide carrying the bearing for the distributing roller. (See Figs. 11 and 13.)

Each of these bearings is provided with a fork 173, the tines of which are received at the respective sides of the outer portion of the slide on which it is mounted. Each of these tines is provided with a bearing 174, in, which a bushing 175, is received, a bolt 176 being journaled in said bushings and having a nut 177 fixed thereto at one end and a head at its other end, endwise movement of said bolt being prevented by said nut and head. A cam block 178 has threaded connection with said bolt and coacts with the walls of the cam slot 179 in the outer end of the slide. This cam slot slants in the plane of the guideway 171 in a direction transverse to the plane of the fork.

The adjustment of this cam block adjusts the bearing block carried by the fork laterally, for adjusting the end of the distributing roller laterally, each end of the distributing roller being separately adjustable by similar means, in order that parallelism between the cooperating contact portions ofthe distributing rollers and the reciprocating roller may be obtained.

After these adjustments are made the parts are clamped in adjusted positions at the respective sides of the press by clamping means exemplified as comprising, at the feed side, a washer 181 received about the cam sleeve 131 inside the segment gear 144 the latterform'rng a shoulder bearing on the clamping washer. (See Figs. 4, 5 and 13.) The clamping washer in turn bears upon the slides 157, 167, 168 and 169. The latter bear upon the supporting plates 121 and 122, and the latter bear upon the frame.

The outer end of the sleeve73 is threaded and has ,a nut 182 received thereover. The nut has an operating handle 183 thereon. (Sec Figs. 1. 4, 5 and 13.)

The cam sleeve 131 has an extension 184 which extends through a bearing 185 of the bearing spider 32. The nut 182 bears on the end of the extension and forces the cam sleeve inwardly, whereby the shoulder thereon, formed by the segment gear-144 bears upon the clamping washer 181 and clamps the slides and the supporting plate toward the frame, for maintaining the parts in adjusted positions.

Theform rollers are provided with axles 191, 191, at their respective ends, the axles 191 being journaled in bearings 192, 193, 194, 195.

Means are provided for adjusting each of the form rollers independently at each end, toward and from the reciprocating roller coacting therewith, and means are provided for adjusting each end of each of the form rollers laterally about the reciprocating roller coacting therewith, toward and from the printing form. These reciprocating rollers are located between the form rollers of each pair of form rollers, as hereinbefore described.

Each of the bearings for the form rollers is provided with a cap 196, which is readily movable for removing the roller, these caps being hinged on pintles 197 and clamped in positions by bolts 198 threaded to the base of the bearing. (See Fig. 16.)

The bearings for the respective form I rollers are mounted on slides 201, 202, 203

and 204, respectively slidable on guideways 205, 206, 207, 208, on arms 209, 210, 211, 212. (See Figs. 16 and 19 to 26 inclusive.)

The guideway 208 for the lowermost form roller is mounted on the arm 212. (See Figs. 1, 2 and 16 to 26 inclusive.) The bearing 195 is provided with a fork shown at 213. the tines of which are provided with holes 214, in which bushings 215 are located. (See particularly Figs. 16, 17 and 18.) A bolt 216 is received through said bushings and is threaded to a cam block 217, slidable in a cam groove 218 in the arm 21-2. The bolt is provided with a nut 219 fixed thereto, the bolt being held in endwise relation by the head of the bolt and said nut, so that rotation of the bolt will cause axial movement of the cam block 217 in the cam slot, for moving the bearing on the guideway, for lateral adjustment of one end of the form roller therein.

There are similar parts at the other end of the roller, designated by similar but primed reference numerals, for moving the other end of the roller in similar manner.

The bearing 194 for the intermediate lower form roller is on the slide 203, which is adjustable laterally 011 the guideway 207 on the arm 211. (See Figs. 21 and 22.) The bearing 194 is provided with a fork 220 similar to the fork shown at 213, and is adjustable on the guideway 207, by a bolt and cam block and connections therefor, similar to the bolt 216 and the cam block 217 and connections therefor, described with reference to the lowermost form roller 114, (see Figs. 17, 18, 19 and 20). The parts are designated by similar reference numerals.

There are similar parts at the other end of the intermediate lower form roller, designated by similar but primed reference numerals.

The bearing 192 for the axle of the uppermost form roller is at one end mounted on the slide 201, which has thereon a fork 221 similar to the fork 213, and is adjustable on the guideway 205 by a'bolt and cam block and connections therefor, similar to the bolt 216 and the cam block 217 described with reference to the lowermost form roller, these parts are designated by similar reference numerals. (See Figs. 16 to 20, 23 and 24.)

The bearing 193 for the intermediate upper form roller is on the slide 202 which is adjustable laterally on the guideway 206 of the arm 210. (See Figs. 25 and 26.) This slide is provided-with a fork 222 similar to the fork 213 and is adjustable on the guideway 206 by a bolt and cam block and connections therefor, similar to the bolt 216 and the cam block 217 described with reference to the upper form roller. These parts are designated'by similar reference numerals.

The adjustments just described of the bearings of the various form rollers at their respective ends on their gnideways. are for the purpose of adjusting the form rollers laterally with relation to the reciprocating rollers 87. 88. in order to obtain proper ink transferring contact between reciprocating rollers and said form rollers throughout their lengths.

Means are also provided for adjusting said form 'rollers toward and from the printing form, in order to obtain proper ink transferring contact between each of the form rollers, throughout its length, with the printinc lines on the printing form. In order that such adjustment with relation to the printing form may not affect the adjustment or relation of the form rollers with the reciprocating rollers with which they respectively coact, such adjustments are made about the axes of said respective reciprocating rollers. These adj ustmcnts will now be described.

The arm 212 for the lowermost form roller has a bearing about a journal sfub 226 on an arm 227. The axis of this bearing is substantially coincident with the axis of the reciprocating roller 88 with which the form 3 means roller thereon coacts, when said form roller is in Operative position. The arm 227 is provided with a bearing 228 in which there is a bushing 229 which has a bolt 230 therethrough. (See Figs. 6, 7, and 16 17, 19 and 20.) The arm 212 is provided with a cam groove 231 in which a cam block 232 is slidable. This cam groove slants toward and from the form roller which it adjusts, and at substantial right angles to the inclination of the cam groove 218.

The cam block has threaded connection with the bolt 230. The bolt has a nut 233 fixed thereto, there being a washer 234 between said nut and the arm 212 across the end of the opening of the cam groove. The bolt is held endwise between its head and said nut. Rotation of the bolt in one direc tion'or the other moves the cam block axially thereon and the coact-ing cam surfaces between said cam block and the walls of said cam groove cause the arm 212 to be rocked on the stub 226, whereby the bearing 195 is caused to move laterally in one direction or the other, substantially about the axis of the reciprocating roller eoacting therewith, for adjusting an end of the form roller 114 toward and from the form cylinder.

The means for adjusting the arm 212' at the other end of the lowermost form roller com rises similar parts designated by similar )ut primed reference numerals. (See Fig. 6.)

The arm. 211 for the intermediate lower form roller has a bearing 235 about a 'ouriial stub 236 on an arm 237. The axis 0 this hearing is substantially coincident with the axis of the reciprocating roller with which the form roller thereon coacts, when said form roller in operative position. The arm 237 is provided with a bearing 23-2) in which there is a bushing 239 which has a belt 249 therethrough. (See Figsti. 7, 16, 21 and The arm 211 is provided with a cam groove 241 in which a cam block 242 is slid-- able. This cam groove and this cam blocir are similar in construction and operation to the cam groore 231 and the cam block 232. i Fig. 17.}

This cam block has threaded connection with the bolt 240. fixed thereto, there being a washer 244 be" tween said nut and the arni 211 across the end of the opening of the cam groove. The bolt is held endwise between its head and said nut.

The arm 247 provided with a bearing 248 in which there is a bushing 249 which. has a bolt 250 thei'ethrough. -(See Figs. 6, 7, 16, 23-and 24.) The arm 209 is provided with a cam groove 251 in which a cam block 252 is slidable. This cam groove and this cam block are similar in construction and operation to the cam groove 231 and the (See Fig. 17.) i

This cam block has threaded connection with the bolt 250. The bolt has a nut 253 fixed thereto, there being a washer 254 between said nut and the arm 209 across the end of the opening of the cam groove. The bolt is held endwise between its head and said nut. Rotation of the bolt in one direction or the other moves the cam block axially thereon and the coacting cam surfaces between said can block and the walls of said cam groove cause the arm 209 to be rocked on the stub 246, whereby the hearing 192 is caused to move laterally in one direction or the other, substantially about the axis of the reciprocating roller coacting therewith, for adjusting an end of the form roller 111 toward and from the form cylinder.

The means for adjusting the arm 209 at the other end of the uppermost form roller comprises simi ar parts designated by similar but primed reference numerals. (See Fig.

The arm 210 for the intermediate upper form roller has a bearing 255 about a journal stub 256 on an arm 257. The axis of this hearing is substantially coincident with the axis of the reciprocating roller 87 with which the form roller thereon coacts when said form roller-is in operative position. The arm 257 is provided with a bearing 258 in which there is a bushing which has a bolt 260 thereih'rough. (See Figs. 0, 7, 16, 25 aud 20.) 'iihe arm 210 is provided with a cam groove 261 in which a cam blot-k 'ihis cam groove and this cam block are sin'iilar in roustructiou and operation to the rain grooie 231 and the cam block 232. (See Fig. 17.)

This cam blocli has threaded connection with the bolt 260. The bolt has a nut 263 fixed thereto, there being a washer 264 between said nut and the arm 210 across the end of the opening of the cam groove. The bolt is held endwise between its head and said nut. Rotation of the bolt in one direction or the other moves the cam block axially thereon and the coacting cam surfaces between said cam block and the walls of said cam groove cause the arm 210 to be rocked on the stub bearing 256, whereby the bearing 193 is caused to move laterally in one direction or the other, substantially about the axis of the reciprocating roller coacting therewith, for adjusting an end of the form roller 112 toward and from the form cylinder.

The means for adjusting the arm 210' at the other end of the intermediate upper form roller comprises similar parts designated by similar but primed reference numerals. (See Fig. 6.)

Means are further provided for simultaneously moving the form rollers in directions toward and from the form cylinder, and means are also provided for simultaneously moving the form rollers toward and from the reciprocating rollers with which they respectively coact. These means are preferably so arranged that these movements may be independent and preferably sequential, in such manner that the form rollers may be, firstly, moved away from the form cylinder, while their ink transferring contacts are maintained with the reciprocating rollers, and, secondly, so that the form rollers may be moved away from their respective reciprocating rollers. The movements in reverse directions are in reverse sequence.

The objects of these respective movements are, f stly, that the form rollers may be moved away from the form cylinder. in order that proper and even ink distribution on the rollers may be eli'ected, for instance, in inking up the press, while the form rollers are out of contact with the form cylinder, and so that, secondly, the form rollers may be moved out of contact with the reciprocating rollers as well as with the form cylinder, in order that the form rollers and the reciprocating rollers may be readily cleaned, arid, so that the form rollers, which are composition rollers, may, when the press is idle, be moved so that their surfaces are free of contact, in order that the cylindrical forms of their outer eripheries may not be disturbed, as by the t in'mations of flat spots or impressions therein.

The means for efl'ecting these movements are instanced as comprising eccentri's or cams fixed to rotate with a cam sleeve 151, which extends across the press, and by providing each of the arms, on which the respective form rollers are mounted, with a pair 01 cam slots, with which a pair of the cams on the cam sleeve coact, the pairs of cams and cam slots being so arranged that the desired movements of the arms for the described movements of the form rollers may be effected. (See Fig. 4.)

Thus the arm is provided with a guideway 271 in wh ch a guide block 272 is received, the guide block being rockable on the flanged Ieeve-QZ. (See Figs. 6, 7, 1(3, 19 and 20.) The inner end of said arm is provided with two cam slots 273, 271, in which cams 275, 27G, fixed to rotate with the cam sleeve 151, are rotatable. This cam sleeve extends across the machine so as to connect the cams at the respective sides of the printing press, in order to simultaneously move both ends of the form "ollcr 114.- It will he noted from Figs. 19 and 20 that said cam slots are arranged in crossing relation, and that the cams are arranged in substantial oppositely extending relation for obtaining the desired sequential movements of'the arm 227.

This cam sleeve extends across the machine so as to connect the cams at the respective sides of the printing pres-=, in order to sinmltaneously move both end: of the form roller 113. It will be noted from Figs. 21 and that said cam slots are arranged in crossing relation, and that the cams are arranged in substantial oppositely extending relation for obtaining the desired sequential movements of the arm 237.

The arm 247 is provided with a guideway 291 in which a guide block 292 is received. the guide block being rockable on the flanged sleeve 91. (See Figs. '6. 7. 1t). 2.; and :34.) The inner end of said arm is provided with two cam slots 29 294. in which callus 29.3. 296, fixed to rotate with the cam sleeve 15]. are rotatable. This cam sleeve extends across the machine so as to connect the cams at the respec ive sides of the printing pre-s. in order to simultaneously move both ends of the form roller 111. It will be noted from Figs. 2; and 24 that said cam slots are arranged in crossing relation, and that the cams are arranged in substantial oppositely extending relation for obtaining the desired sequential movements of the arm 247.

The arm 25? is provided with a guideway 301 'in which a guide block 302 is received. the guide block being rockable on the Hanged sleeve 91. (See Figs. (3. 7, 1(3, 25 and 2G.) The inner end of said arm is provided with two cam slots 303, 304, in which cams 3H3, 306, lixed to rotate with the cam sleeve lfil. are rotatable. This cam sleeve erlends across the machine so as t connect the cam ill at the respective sides of the printing press, in order to simultaneouslymove both ends of the form roller 112. It will be noted from Figs. and 26 that said cam slots are arranged in crossing relation, and that the cams are arranged in substantial oppositely extending relation for obtaining the desired sequential movements of the arm 257.

The construction and relation of parts for effecting the movements of the form rollers toward and away from the form cylinder and toward and away from the reciprocating rollers coacting therewith are illustrated in Figs. 19 to 26 inclusive.

19 shows the adjustment of the lowermost form roller for normal printing relation.

Fig. 20 illustrates the relation of this form I roller and the parts for effecting such relation. when the form roller is moved away from the form cylinder and also away from the lower reciprocating roller.

Fig. 21 illustrates the normal position of the intermediate lower form roller and the parts for controlling the position of the same, whereas Fig. 22 shows the positionsof the intermediate lower form roller away from the form cylinder and its coacting reciprocating roller.

itwill be noted from a comparison of Figs. 20 and 22 that the movements of the lowermost form roller and of the intermediate lower form roller are in opposite directions with relation tothe reciprocating roller therebetween.

Fig. 23 shows the normal position of the uppermost form roller and its positioning parts, whereas Fig. 24 shows the free position of said form roller and the relations of the corresponding positioning parts.

Fig. 25 shows the normal position of the intermediate upper form roller and its positioning parts, and Fig. 26 shows the free position of said form roller and its positioning parts.

The movements of the form rollers are controlled by the hand wheel 145 on the shaft 130 hereinbefore described. (See Fig. 4.)

The cam sleeve 151 surrounds the shaft 150. This cam sleeve has a Worm gear 311 fixed thereto. (See Figs. 4, 7 and 15.) A worm 312 is journaled i'n bearings 313, 314, of a plate 315 rotatable about and with said shaft. A pull-pin '316 is axially movable in a bore 317 in an extension 318 of the segment gear 149. A spring 319 normall urges said pull pin into a hole 320 in sai plate, for connecting said platewith said segment gear, in order to cause the two to move together. The segment gear is rotated by the hand wheel 145 in manner hereinbefore described, (see i "i;,rs. 4, 5, 6 and 7), the rotation of this segment gear carrying the worm plate 315 with it, when said worm plate is connected with said segment gear by means sleeve.

The sleeve 91 has the clamp block 321 thereabout in a bearing 322 of the bearing spider 32. (See Figs. 1, 2, 6 and 7.) The outer end of the sleeve is threaded and has a nut 323 thereon. The clamp block bears against the arm 257 (referring to the upper part of Fig. 7 which bears upon the arm 210, which in turn bears upon the arm 209, the latter bearing upon the arm 247, and the arm 247 bearing upon the flange of the sleeve 91, which is fixed to the frame. When the nut is in clamped position, all the parts are clamped together for being securely maintained in their adjusted positions. The nut is provided with an operating handle 324.

The sleeve 92 has a clamp block 331 thereabout in a bearing 332 of the bearing spider 32, (see Figs. 1,2, 6 and 7). The outer end of the sleeve is threaded and has a nut 333 thereon. The clamp block bears against the arm 237 (referring to the'lower part of Fig. 7), which bears upon the arm 211, which in turn bears upon the arm 212, the latter bearing upon, the arm 227, and the arm 227 bearing upon the flange of the sleeve 92 which is fixed to the frame. When the nut is in clamped position all of the parts are clamped together for being securel maintained in their adjusted positions. he nut 333 is provided with an operating handle 334. v

If new it is desired to adjust the relation of the arms individually, the corresponding clamp nuts are released for permitting such adjustment. If it is desired to adjust all of the form rollers simultaneously, the clamp nuts are relieved for relieving pressure-upon the arms and permitting their movements with relation to each other.

If it is desired to move the form rollers and the distributing rollers so as to free the same from contact, the ull pin 316 is allowed to remain in its ho e 320 so as to connect the worm plate 315 with the segment gear 149, so that not only the shaft 150 shall be rotated,-but the cam sleeve 151 will be rotated therewith. Rotation of said shaft controls the position of the distributing rollers, and the rotation of said sleeve controls the positions of the form rollers.

If it is desired to move the form rollers out of contact only with the form cylinder, for distributin the ink evenly upon all of the inking ro lers, the hand wheel 145 is turned so as to release contact between the form rollers and the form cylinder. whereupon the pull in 316 is moved out of its hole 320 for isconnecting the shaft 150 from the cam sleeve 151, whereupon the hand wheel is reversely rotated. for again causing contact between the distributing rollers and the reciprocating roller coacting therewith, While the form rollers are allowed
