The press herein shown is carried upon a frame consisting of substantially identical left and right side plates 31 and 32 united essentially by front and rear cross beams 33 and 34 extending between and secured to the right and left side plates 31 and 32 adjacent the lower edge thereof.

The press herein illustrated comprises an impressing-platen-carrying bed 35 pivoted at its rear edge upon a shaft 36 extending between the rear upper corners of the frame side plates 31 and 32 and operable between upper impressing position and lower retracted position by means of a pair of toggles 37 each comprising first an upper link 38 pivoted at its upper end to a cross shaft 339 carried by the bed 35 and at its lower end to a toggle shaft 39 common to the two toggles 37, and second a lower link 47 pivoted at its upper end to the toggle shaft 39 and at its lower end to bosses 41 rising from the front cross beam 33. The toggles 37 are straightened or extended by means of a pair Aof cams 42 carried by an operating shaft 43 and engaging rollers 44 mounted on the toggle shaft 39, and are broken or retracted by means of a pair of cams 45 also carried by the operating shaft 43 and engaging rollers 46 carried by the rear ends of reciprocable members 47a connected at their front ends to the toggle shaft 39 and guided by embracement of the operating shaft 43 between spaced guiding surfaces 48 formed on the members 47a intermediate the front and rear ends thereof.

The operating shaft 43 is driven from a drive shaft 49 by means of a pinion 50 carried on the drive shaft 49 and engaging a gear 51 carried on the koperating shaft 43, and the drive shaft 50 is actuated in any suitable manner, as by means of an electric motor suitably connected thereto, not shown herein.

Mounted upon the front upper corners oi the frame side plates 31 and 32 is a fixed upper platen 52 adjustably secured in position by means of four supports 53 disposed at the four corners of the fixed platen 52 and each comprising a stud 54 provided at its lower end with a lower screwthreaded reduced extension 245 extending through a suitable aperture 246 in a boss 55 extending from the corresponding side plate 31 or 32, and at its upper end with an upper screw-threaded extension 247 extending through a suitable aperture 248 in a boss 56 extending from the corresponding corner of the fixed platen 52, a nut 57 engaging the lower reduced extension 245 to secure the stud 54 firmly in fixed position rising from the corresponding boss 55, and a pair of nuts 58 and 59 engaging the upper screw-threaded extension 247 of the stud 54 above and below the boss 56 extending from the fixed platen 52 to thus hold the fixed platen 52 firmly mounted at that elevation determined by the adjusted position of the upper and lower nuts 58 and 59 upon the upper extension 247.

Projecting from the right end of the fixed upper platen 52, bolted thereto, are a pair of arms 60 carrying horizontally alinedinner and outer trunnions 61 and 62 rotatably supporting, respectively, a plain inner web-guiding roller 63 and a taper-flanged outer web-guiding roller 64, carrying also a plate 294 supporting a weight 295 spaced from the plate 294 by the web and acting to impose tension upon the web therebeyond; extending from the lower portion of the outer face of the right side plate 32 are a pair of arms 65 carrying at their ends bearing boxes 66 in which are mounted anti-friction rollers 67 adapted to rotatably support thershaft 68 of `the web roll 69; while extending from the upper portion of the outer face of the left frame side plate 31 are a pair of brackets 70 carrying web feeding and severing mechanism 71.

The web feeding mechanism herein shown comprises an upper roller 72 mounted upon a shaft 73 rotatably supported in supporting plates 74 rising from the brackets 70, and a lower roller 75 mounted upon a shaft 76 rotatably supported in a frame 77 pivoted at its upper end upon the shaft 7S of the upper roller 72 and having its lower end adjustably secured in position by means of links 78 pivoted at their outer ends to a cross shaft 79 mounted in the lower end of the frame 77, pivoted at their inner ends by pivot pins 249 to the free ends of arms 80 extendingfrom a shaft 81 mounted in the supporting plates 74, and operable, Vto swing the arms 80, and reciprocate the links 78, and oscillate the frame 77, by means of a screw 82 rotatably and non-reciprocably mounted in a boss 83 projecting from one of the supporting plates 74, operable by means of a crank 84, and engaging within a correspondingly screwthreaded aperture traversing a lug 85 formed on the pivot-pin 249 connecting that arm 80 with the corresponding link 78.

The web is held in engagement with each of the upper and lower rollers 72 or 75 by means of two pairs of auxiliary rollers 86 each pressing one edge of the web against the corresponding upper or lower roller 72 or 75, and each rotatably mounted upon a pair of studs 87 projecting from a carrier plate 88 provided with a stud 89 by which it is in turn pivotally mounted upon an arm 90 secured, by means of a bolt 91 acting upon the split ends 92 of the hub of the arm 90, and in a desired adjusted position, on either the shaft 79 joining the lower ends of the frame 77, or on a shaft 93 connecting the upper extremities of the supporting plates 74; the lower roller 75 is operated from the upper roller 72 by means of an intermediate gear 94 carried by a shaft 95 rotatably mounted in the frame 77 and engaging cooperating gears 96 and 97 mounted respectively on the shafts 73 and 76 or the upper and lower rollers 72 and 75: and the upper roller 72 is operated, from a jack-shaft 98 driven from the operating shaft 48 by means of cooperating equal gears 99 and 100 carried respectively by the operating shaft 43 and the jack-shaft 98, by means of a rack 101 reciprocable in suitable guides 102 projecting from the corresponding supporting plate 74, co-acting with a pinion 103 rotatably mounted upon the shaft 73 of the upper roller 72 and carrying a dog 104 engaging a ratchet 105 fixed to the upper-roller shaft 73, and operated by means of a link 106 connected to a crank-arm 107 secured to the left end of the jack-shaft 98 adjustable on the jack-shaft 98 by means of an adjusting screw 109 and tovary the throw, and held in adjusted position by means of a cap screw 108 entering the end of the jack-shaft 98 through a slot 254 in the crankarm 107 and over-lying the two sides of the arm 107 to secure the arm 107 firmly to the end of the jack-shaft 98 in that adjusted position defined by the position of the adjusting screw 109 and effective to produce that crank-throw effecting that extent of reciprocation of the rack 101 which produces the desired rotation of the rollers 72 and 75, and therefore the desired advance of the web.

The web severing means herein shown comprises a fixed knife 110 carried by the supporting plates 74, and a movable knife 111 pivoted at 112 to a bracket 113 extending from the corresponding supporting plate 74, provided with a bell-crank arm 114 normally held retracted in any desired manner, as by means of a spring (not shown) extending downwardly from the bell-crank arm 114, operated from the jack-shaft 98 by means of a link 115 pivoted at its upper end to the bell-crank arm 114, guided at its lower end by a fork 116 embracing the jackshaft 98, and carrying adjacent the fork 116 an actuating roller 117 operated by a cam 118 mounted upon the jack-shaft 98. In order to hold the web firmly during the cutting operating the cutting means herein shown also comprises a weight 119 pivoted upon a cross shaft 120 mounted in the supporting plates 74, biased to Web-holding position by gravity, and raised from web-holding position except during the severing operating by engagement of the upper edge of the movable knife 111 with a pin 121'projecting from the upper end of a bracket 122 secured to the weight 119 by means of suitable machine screws 123.

Rotatably mounted in lugs 274 depending from the arms 60 is a shaft 275 to which are fixed a pair of arms 276 and 277 joined adjacent their free ends by a cross rod 278, rotatably supporting at their free ends the shaft 279 of a web-slackening roller 280, and operated by means of a link 281 provided at its lower end with an aperture receiving a pin 282 carried by an extension 283 projecting radially inwardly from the journal pin 132 of an impressing-platen operating-crank 133 carried by the operating shaft 43, provided at its upper end with an aperture receiving a pin 284 projecting from a connector 285 itself provided with an aperture receiving a pin 286 carried by the arm 277, and operating the arms 276 and 277 upon rotation of the operating shaft 43 to move the web-slackening roller 280 between a lower or retracted position in fJi which the web-slackening roller 280 is free of the web and an upper or advanced position in which the web-slackening roller 280 has drawn web from the web roll 69 to provide a slack just ahead of the outer taper-flanged web-guiding roller 64 greater than the maximum web feed.

Also supported upon the outer face of the right side plate 32 are a pair of bracket arms 287 secured to the side plate 32 by means of suitable bolts 288 and provided at their outer ends with bearing bosses 289 rotatably supporting the shaft 290 of a web guide roller 291.

It will of course be understood that the web passes from the web roll 69 behind the web guide roller 291 over the web-slackening roller 280, thence over the outer web-guiding roll 64 and under the inner web guiding roll 63, thence across the lower face of the xed upper platen 52, thence around the lower feed roll 75 and the upper feed roll 72, and finally across the fixed lower knife that the web is advanced intermittently by the operation of the feed rolls 72 and 75, and by a distance determined by the adjustment of the crank-arm 107; that the web is severed intermittently by the operation of the upper movable knife 111, the severed section falling upon a table 293 suitably supported from the supporting plate 74; that after each advance of the web by the web feeding rolls '72 and 75 the web-slackening roller 280 is raised or advanced to draw web from the web roll 69 to form in the web just ahead of the taper-Hanged web-guiding roll 64 a slack greater than the extent of a web feed; and that upon the succeeding advance of the web by the feed rolls 72 and 75, and the consequent taking-in of the slack in the web ahead of the taper-flanged webguiding roll 64, the web will be drawn down the tapered sides 292 of the taper-anged Web-guiding roll 64 into position exactly alined with the impression mechanism of the press.

Mounted upon the upper face of the bed 35 is an impressing platen 124 which is held against sidewise movement relative to the bed 35 by means of strips 125 securedto the impressing platen 124 by means of suitable machine-screws 126 in position engaging the lateral edges of the bed 35, is reciprocable on the bed 35 from front to back along the guideways formed by the strips 125 and the lateral edges of the bed 35, and is reciprocated upon the bed 35, between forward position opposite the fixed platen 52, with the forms 127 carried by the impressing platen 124 in position to cooperate with the tympan 128 carried by the fixed platen 52 to impress that portion of the web lying therebetween, and retracted position withdrawn from below the fixed platen 52, and in passing to and from which the forms 127 are inked by suitable form-inking rollers, by means of a lever 129 pivoted at 120 to the right side plate 32, operated by means of a link 131 pivoted at one end to the pin 132 carried by the crank-arm 133 carried by the operating shaft 43 and at the other end at 134 to an intermediate point in the lever 129, and pivoted at its upper end at 135 to a rack 136 meshing with a gear 137 mounted on a cross-shaft 138 carrying adjacent its ends gears 139 meshing with racks 140 carried by the two side edges of the impressing platen 124.

rIhe rack 136 is held in engagement with the gear 137 by means of a roller 269 pivoted upon a stud 270 projecting from the corresponding side plate 250 of the bed 35 and engaging the lower face of the rack 136. l

Under certain circumstances the movement produced by the substantially harmonic motion of the crank-arm 133 will maintain the impressing platen 124 substantially stationary over that period during which the forms 127 are in contact with the web, but in order to insure that there is no reciprocatory movement of the impressing platen 124 during that period I prefer to provide compensation for the impressing platen drive, and I therefore mount the shaft 133 in journals 141 reciprocable in slots 142 formed in the sides 250 of the bed 35, normally held fixed against reciprocation in the slots 142 of the bed 35, but reciprocated during the time the form may be in contact with the web the exact amount necessary to compensate for the slight reciprocation of the impressing platen 124 which may be produced by the crank-arm 133, thus to insure that the impressing platen 124 does not reciprocate to any extent whatever while the forms 127 may be in engagement with the web, the operating means for the journals 141 yof the shaft 138 being herein shown as comprising links 143 terminating at their forward ends in collars 251 embracing the shaft 138 and having their rearward ends pivoted at 144 to arms 145 fixed to a shaft 146 mounted in the sides 250 of the bed 35 and pro-vided with a bell-crank arm 147 pivoted at 148 to a link 149 which is guided at its lower end in any suitable manner, as by a fork (not shown) embracing the operating shaft 43, and is operated from a cam 150 carried by the operating shaft 43 by the action of the cam l150 upon a roller 266 carried by the link 149 adjacent the lower end thereof.

With this arrangement the immobility of the impressing platen 124 may be additionally insured by the use of any suitable registering device interposed between the impressingplaten 1.24 andthe fixed upper platen 52, such as pins 252 projecting from the upper fixed platen 52 in position to engage with registering apertures 253 in the impressing platen 124, and in such case I may dispense with any attempt to cause the compensating mechanism to compensate exactly for the motion otherwise produced in the im pressing platen 124 by the crankarm 133, and may depend on the registering means alone to exactly register the two platens 124 and 52, and to hold the two platens 124 and 52 registered while the form may be in engagement with the web, and accordingly in such case I may utilize the compensating mechanism only to disable the normal drive from the crankarrn 133 to permit the registering mechanism to operate.

In the event that the press is being used only for embossing, so that inking is not required, I may disable the impressing-platen reciprocating mechanism in any desired manner, as by disconnecting any two parts in the operating train, or by maintaining the link 149 in raised position, or otherwise.

Mounted upon the sides 250 of the bed 35 by means of suitable bolts 262 are a pair of side brackets 151 supporting mechanism for inking the forms.

Reciprocably mounted in the upper rear corners of these side brackets 151 is an operating rod 152 provided at one end with a rack section 153 engaging a gear 154 carried by a jack-shaft 155 suitably supported from the corresponding side bracket 151 and operated by means of a second gear 156 actuated by a rack 157 driven through a link 158 from a lever 159 pivoted at 160 to the left side plate 31 and operated by means of a link 161 from a crank-arm 162 carried by the left end of the operating shaft 43 adjustable on the operating shaft 43 by means of an adjusting screw 163'and to vary the throw, and held in adjusted position by means of a capscrew 164 entering the end of the operating shaft 43 through a slot 255 in the crank-arm 162 and over-lying the sides of the crank-arm 162 to hold the crank-arm 162 firmly to the end of the shaft 43 in its adjusted position.

Mounted on the operating rod 152, secured thereto by means of machine-screws 165 to partake of the reciprocation of the operating rod 152, and additionally supported by a cross-rod 271 xed in the two side brackets 151 and extending therebetween, are a plurality of platforms 166 each carrying secured thereto by suitable bolts 167 an ink-supply means 168 herein shown as comprising a reservoir 169 from which ink is delivered in substantially the usual manner by means of an ink-delivery roller 170. Pivotedto each of these inksupply means 168 is a frame 171 carrying at its free end a shaft 177 to which is fixed an intermediate roller 172 movable into an upper position engaging the ink-delivery roller 170, or into an intermediate free position, or down into position engaging the then upper face 263 of a polygonal intermediate bar 173 rotatably mounted in the side brackets 151; mounted upon the shaft 177 is a dog 174 engaging a ratchet 175 fixed to the shaft of the ink-delivery roller 170 and operating to advance the ink-delivery roller 170 upon each movement of the intermediate roller 172 into engagement with the ink-delivery roller 170; and rotatably mounted in bearing plates 258 carried on the outer end of the frame 171 are a pair of mixing rollers 176 engaging the intermediate roller 172 to mix the ink delivered to the intermediate roller 172 by rotation with the intermediate roller 172 beforethe intermediate roller 172 engages the intermediate bar 173 to deliver the ink to the intermediate bar 173.

Also mounted in the side brackets 151 is a control bar 178 carrying parallel to itself a drive rack 179; fixed to the shaft 177 of the intermediate roller 172 in position to engage the upper face of the control bar 178is a disc 180; and rotatable upon the shaft 177 of the intermediate roller 172 is a gear 181 meshing with the drive rack 179, provided on its inner face with a ratchet 182 arranged to engage a cooperating ratchet 183 carried by the abutting face of the disc 180, and spring pressed toward the disc 180, to maintain the ratchet 182 in engagement with the ratchet 183, by means of a spring 184 compressed between the outer face of the gear 181 and a nut 185 carried by the end of the shaft 177 of the intermediate roller 172. Provided at each end of the control bar 178, on the lower face thereof, are cam surfaces 186 riding on cam pins 256 carried by the side brackets 151 and effective, upon slight reciprocation of the control bar 178, to raise the control bar 178 from that position in which it is slightly depressed below the disc 180 as thev intermediate roller 172 engages the then upper face 263 of the intermediate bar 173, through the position in which the control bar 178 has engaged the disc 180 to raise the intermediate roller 172 out of engagement with the intermediate bar 173 but not yet into engagement with the ink-delivery roller 170 of the ink-supply means 168, and then into the position in which the intermediate roller 172 is raised into engagement with the ink-delivery roller 170.

The teeth on the gear 181 and on the drive rack 179 are formed of sufficient length so that the gear 181 and the drive rack 179 remain always in mesh.

nasa-oso Underfthese circumstances it will be obvious ythat if the control bar 178 is reciprocated to move `from depressed to elevated position the intermediate roller 172 will be raised from contact with the intermediate bar 173 to contact with the inkdelivery roller 170, and the dog 174 will simultaneously rotate the ink-delivery roller 170 through engagement with the ratchet 175 carried by the shaft 177 of the ink-delivery roller 170; that if the control bar 178 is now partially retracted the intermediate roller 172 will drop to intermediate position out of engagement with both the inkdelivery roller 170 and the intermediate bar 173; that if the ink-supply means 168 is now reciprocated the gear 181, far smaller than the intermediate roller 172, and therefore spun by its engagement with the drive rack 179, will operate through the ratchet 182-183 to spin the intermediate roller 172 to cause the intermediate roller 172, in cooperation with the mixing rollers 176, to thoroughly mix the ink deposited on the intermediate roller 172 by the ink-delivery roller 170; that if the control bar 178 is now fully retracted the intermediate roller 172 will drop into depressed position with the disc 180 out of contact with the control bar 17 8 and the intermediate roller 172 engaging the then upper face 263 of the intermediate bar 173; and that if the ink-supply means 168 is now reciprocated in the reverse direction the spinning of the gear 181 by the drive rack 179 will be ineffective to rotate the intermediate roller 172 because of the interposition of the ratchet 182-183, and the intermediate roller 172 will roll along the then upper face 263 of the intermediate bar 173 at surface speed transferring the mixed ink from the intermediate roller 172 to the intermediate bar 173.

Reciprocation of the control bar 178 in coordination with the reciprocation of the ink-supply means 168 is effected by a cam 187 mounted on the operating shaft 43 and acting upon a cam roller 188 caried by the lower end of a link 189 guided at its lower end in any suitable manner, as by a fork (not shown) embracing the operating shaft 43, and pivoted at its upper end to the arm 190 of a bell-crank lever 191 pivoted upon the pivot shaft 36 of the bed 35 and provided with a second arm 192 to which is pivoted at 193 a rack 194 engaging. a gear 195 loosely mounted upon the shaft 197 of the intermediate bar 173 and carrying a cam 196 provided with a cam groove 198 co-acting with a pin 199 projecting from the control bar 178.

Reciprocably mounted between cooperating guides 200 carried by the two side brackets 151 are a pair of slides 201 together supporting a shaft 267 carrying adjustably secured thereto arms 268 carrying the shaft 202 of a transfer roller 203 adapted upon retraction of the slides 201 to contact with the then lower face 263 of the intermediate bar 173 to receive ink therefrom, and upon advance of the slides 201 to contact with and transfer this ink to an ink-receiving roller 204 forming one of a series of rollers by which the ink is applied to the forms.

Inasmuch as the ink is applied by the intermediate roller 172 to the then upper face 263 of the intermediate bar 173, and is taken by the transfer roller 203 from the then lower face 263 of the intermediate bar 173 it is of course necessary that the intermediate bar 173 be rotated, and I there fore provide means for this purpose, this means 4being herein shown as a dog 205 carried by the control bar actuating cam 196 and engaging, upon oscillation of the cam 196 in one direction, with a ratchet 206 secured to the intermediate bar 173, the inter-engagement of the dog 205 With the ratchet 206 being such that each operation of the cam 196 will rotate the intermediate bar 173 a quarter revolution.

To facilitate this rotation of the intermediate bar 173 the corners of the intermediate bar 173 are chamfered, as shown at 264.

The transfer roller 203 is reciprocated in synchronism with the other mechanism of the press by means of a cam 207 mounted on the operating shaft 43 and engaging a roller 208 carried by the lower end of a link 209 guided at its lower end in any suitable manner, as by a guide link 272 pivoted to the right frame side plate 32 at 273, and secured at its upper end 210 to the arm 211 of a bell-crank lever 121 pivoted on the pivot shaft 36 of the bed 35 and provided with a second arm 213 to which is pivoted at 214 a link 215 pivoted at its other end at 216 to an arm 217 secured by means of a hub clamp 218 in the desired adjusted position upon a shaft 219 mounted in the side brackets 151 and carrying a pair of sectors 220 engaging racks 221 formed on the lower faces of the slides 201; while the mechanism for actually applying the ink to the forms after it has been supplied to the receiving roller 204 by the transfer roller 203 comprises three alined form-engaging rollers, a iirst form-engaging roller 222 directly engaging the receiving roller 204, and a second form engaging roller 223 and a third form-engaging roller 224 both engaging a carrier roller 225 receiving ink from the receiving roller 204 through a supplemental roller 226. The form-engaging rollers 222 and 223 and 224 are mounted upon shafts 227 the ends of which are received in bearing blocks 228 adjustably secured, by means cf machine-screws 229 passing through slots 265 in the bearing blocks 228, to supporting plates 230 receiving the machinescrews 229 and themselves supported by means of studs 231 from the side brackets 151, and adjusted to that position effective to secure the form-engaging rollers 222 and 223 and 224 at the proper level to roll over the top of the forms as the forms are drawn under these form-engaging rollers upon retraction and subsequent advance of the impressing platen 124; the supplemental roller 226 is mounted upon a shaft 232 supported in bearing plates 233 rising from the side brackets 151; and the carrier roller 225 and receiving roller 204 are mounted on shafts 234 and 259 rotating in bearing apertures 235 and 260 in the side brackets 151 and carrying pinions 236 and 261 meshing With a gear 237 which is rotatably mounted upon a stud 238 fixed in the corresponding bearing plate 230 and is operated by engagement with a rack 239 carried by the upper face of one side of lthe impressing platen 124 and operated to effect rotation ofthe various rollers as the impressing platen 124, and the forms carried thereby, are retracted and advanced beneath the form-inking rollers 222 and 223 and 224.

It vvl of course be understood by those skilled in the art that I may apply any desired number of ink-supply means 168, and at any desired spacing along the ink-supply means operating rod 152, and that I may adjust the drive for the ink-supply means operating rod 152 to reciprocate the inksupply means 168 to any desired extent, and accordingly that I may so adjust the mechanism that each ink-supply means 168 Will apply ink to any desired portion of the intermediate bar 173, including a condition whereby one or all of the ink-supply means 168 applies ink to the intermediate bar 173 right up to the point at which the adjacent ink-supply means 168 has applied ink to the intermediate bar 173; also that the various ink-supply means 168 may apply inks of different characteristics, such as different colors; and in addition, that the transfer roller 203, and the various distributing rollers, transfer to every section of each form-inking roller 222 or 223 or 224 ink from the corresponding section of the intermediate bar 173, so that the form-inking rollers 222 and 223 and 224 apply ink across the forms at every point of exactly the characteristic of the ink at that point on the intermediate bar 173.

Under some circumstances it becomes desirable to restrict the quantity of ink applied to a particular' portion of the form, and with the mechanism herein shown I may achieve this result conveniently by covering part or all of the corresponding portion of the intermediate bar 173 by means of thin strips 240 held in adjusted position by a clamping bar 241 adapted to be drawn by means of machine-screws 242 into position clamping the strips 240 between the clamping bar 241 and the upper face 242 of an angle bar 243 receiving the machine-screws 242 and itself secured to the side brackets 151 by suitable bolts 244.

It will of course be understood by those skilled in the art that the various parts of the press are all operated in concordance, that the web is slackened during the final portion of the period over which the bed 35 is retracted, and during the advance of the bed 35; that the Web is fed intermediate the period during which the bed 35 is retracted; that the Web is severed While the bed 35 is advanced to bring the impressing platen 124 into impressing relation with the fixed upper platen 52; that the impressing platen 124 is Withdrawn under the form-inking rollers 222 and 223 and 224, and these and the cooperating rollers actuated, and is then advanced, and the various rollers again actuated, while the bed 35 is in retracted position; that the transfer roller 203 is normally in engagement With the receiving roller 204, and operates to take the ink from the then lower face 263 of the intermediate bar 173 while the intermediate roller 172 is applying ink to the then upper face 263 of the intermediate bar 173; that the intermediate roller 172 applies ink to the then upper face 265 of the intermediate bar 173 intermediate the period during which the bed 35 is in retracted position, and therefore operates to receive the ink from the inkdelivery roller 170 just before the advance of the bed 35, and to mix the ink with the aid of the mixing rollers 176 during the balance of the period over which the bed 35 is in retracted position, during Athe advance and retraction of the bed 35, andduring the first part of the succeeding retraction period of the bed 35; and that the intermediate bar 173 is rotated While the intermediate roller 172 is rising to receive the ink from the ink-delivery roller 170, and therefore just before the advance of the bed 35.

From the above description it will be obvious to those skilled in the art that I have provided a printing press embodying various improvements over the presses heretofore known, particularly new and improved means for feeding the web, and new and improved means for mounting and inking the form.

Under these circumstances it will of course be obvious to those skilled in the art that the embodiment of my invention herein shown and described accomplishes at least the principal object of my invention.

At the same time it also will be obvious to those skilled in the art that the embodiment of my invention herein shown and described embodies advantages other than those particularly pointed out and suggested herein, and also that this particular embodiment of my invention may be variously changed and modified Without departing from the spirit of my invention or sacricing the advantages thereof, and accordingly it Will be understood that the disclosure herein is illustrative only, and that my invention is not limited thereto.
