Application filed November 8, 1923.

This invention relates in general to printing presses and has for its principal object the provision of a practical printing press adapted for a change of type at each printingimpression.

il. further object oic the invention is the provision of print-ing press ot this character which will permit of the p inting of a diil'erent name or name and address at the time it prints other matter, as the page ot a catalog.. part of a bool-let, etc.

Another important object ot' the invention is the provision of a press oli this character oi high output, simple construction, and composed o'' Uarts unlikely to require fre- (prentl repair, replacement or rcadjustment, aniV which may be operated by the usual labor available ivithout special or protracted instruction.

The invention contenililatesl the provision ot :a printing press wherein the substituted characters Will print in exact unitority with he unchanged characters and all vill be ilier ot type printing or all of typewriter printing or continuations thereof. he invention is adapted. of course. Ytor varied salutation and address as required iu circular letters, dodgerf-, and the like,

Numerous other objects and advantages ot the invention will be apparent as it is better understood from the following description, which, taken in connection with the acconipanying` drawings, discloses a pretersed ei'nbodiment thereof.

F or the purpose of illustrating my invention I have shown on the drawing a Lrinting press in which it is`embodied. rlhis press has a base 25 of suitable construction and which Will not be described in detail except as may be necessary to an understanding of the active parts of the apparatus. The base supports a press bed 2b'. which is vertically arranged in the present instance and upon which a chase 27 is secured in suitable Jfashion. The detail ot the chase is shown in Fig. l2 from which it will be noted that the chase has the usual outside and inside walls adapted to contain a type bed 28, spacing members 29 and 3l and chase locks 32. On Fig. l2 l have shown a bracket or box setting off a space Eel which the type having a single use is to print.. This box is locked in the chase in the makeup as will be readily understood.

il/hen the chase is positioned upon the bed 2G ot the press this boX is brought in registration with a plate 35 having an aperture 36 with which the bofregiste i, so that an opening is provided through the bed and through the chase for positioning and printing ot the slug or slug groups to be changed at each printing impression. A maffazine ll for holding a supply of slugs or slug groups to be printed is mounted upon a cross frame member 42 behind and above the slug group printing position and a similar magazine or receptacle L3 is arranged adjacent thereto to receive each slug or slug group after printing. The magazines ll and 43 are inclined respectively downwardly to fromA their lower ends which are spaced apart to permit a slug carrier to be arrangel therebetween and to simultaneously receive a slug or slug group from the delivery magazine and feed out previously printed slug or slug group to the receiving magazine see Fig. 8. The slug carrier has a curved movement down troni between the magazines and then is carried bodiljf along a right line into printing position.` During the curved movement it is rotated to turn the slug groups at 900 to their original position.

The slug carrier and its actuating mechanism will now be described. A slide 44 is mounted in horizontal ways 45 in the press 'frame and this slide is provided with a rotatable shaft or pin 46 having bearings at 47 (Fig. 9) in the slide. Between these bearings is arranged a sleeve 48 carrying a forwardly extending arin 49. A shaft 51 is ar anged longitudinally of this arm and extends out beyond its end and is provided with a slug` carrying head 52. Two side walls 53 fixed to the side of the head extend up and engage opposite sides of the slug group 54 as seen in Fig. 9. Viewing Fim 7, which shows the arrangement of the press at the instant of printing, it will be understood that the slide 44 is moved to the left after the printing is accomplished and the slug carrier head is then swung` upwardly about the pivot 46 to bring the slug group between the ends of the magazines.

These motions are accomplished through a train of mechanism., which will now be described. A motor 61 is mounted upon the base the machine and through its pinion 62 drives a gear 63 upon a shaft 647 and a gear 65 upon this shaft meshes with a. gear 66 upon a shaft 67 which carries a cani 68, which cam actuates both the slide in its movement and the upward and downward action of the slug carrier. A lever 71 is pivotcd at 72 in the frame of the press and has a follower' roll engaging in cani groove 73 on one face of cam 68. This lever is connected at its opposite end through a link 74 with the tail 75 of the slide. The link 74 is composed of two parts threadedly engaged, the outer one of which is split and adapted to be locked by set screws 7 6, the purpose of this last being to permit adjustment of the parts. The lever 71 in its movement moves the slide 44 as already described.

The arm 49 is caused to swing upwardly to discharging' position by rearwardly eX- tending` lugs 81 upon shaft 46 between the ends of which is pivoted a link 82 in turn connected with the end of a lever 83. The lever 83 is pivoted on shaft 64 and has a follower roll 84 engaging in a cam groove 85 upon `he opposite face of cani 68. It will be manifest that under the action of this cuan downward movement of the lever from the position shown in Fig. 7 will pull down upon the lugs 81 and swing up the arni 49 to discharge position.

vThe connection between the link 82 and leveler C?, is a yii-ildinn` one andv includes a bolt 87 positioned through a tail 88 of an eye-inuit passing through a sleeve 89 ad- ,instabl'v fixed in a slot 91 in the end of the lever 83. The bolt is embraced by a sleeve 92 between the bo-lthead and the eye bolt and by a spring` 93 beyond the eyebolt. The bolt is threaded into an end 94 of link 82 and is Lesage@ turning' is accomplished during' the arcuate or lifting inoven'ient of the arm 49. A spruig ii at one end to the shaft 51 and at the other end to the arni itself tends or pull the slug carrier into the --osition shown in Fig. 6 on the up-st-rolre or the slur; carrier. (in tne down-stroke a cani 96 engages a roll 97 mounted on a stud shaf., 98 carried by a bracket 99 extending up from the slide. 44. As the arin 49 is swung don-'n the cani 96 engages the roller 97 and the slug group is turned throughout T slugs are fed out of the de- 900. ine livery magazine or chute into the carrier and from the carrier into the receiving magazine as `will bc now described.

After each printing impression the slugcarrier comes into position between the two magazines with the slug or slugv group from which imp gli-lien has just been taken. The two ends of he slug magazines and the carrier itself forni a channel in which at this time two slnfi groups are resting, namely, one in the delivery magazine and one in the carrier, Figs. 7 and 9. A pusher rod is moved transversely against the slugl group at the bottoni of the delivery magazine and pushe it toward and into the carrier, this slug group in turn pushing out the previously printed slug); group into the end of the receiving magazine. Shaft 67 carries a bevel Arear i01 which meshes with a bevel rear 10;? on a shaft 103 mounted in the frame of the machine. This shaft is pro- -.f'idel with a cam 104 in which is engaged a cam roll of a. lever 106 pivoted at 107 on the frame and connected by a link 108 .vith a lever 109 pivoted at 111 in the machine and havingY a bifurcated or slotted end 112 enplaging a head 113 in which is mounted a rod 114 carryingl a slug advancer 115. A second rod 116 carried by the head moves through snit-able bearings to guide the slug` advancer its movement. A removable member or angle 117 is fixed on the advancer to permit the apparatus to be adjusted for various thiclme. of Slug; groups by r-1\n1ovin;i'said member, or substituting others of different thickness.

Preparatory to this feeding' action, the slug 2eroups in the receiving magazine 43 are positively pushed along; the magazine and ont of the of the slug group to be received. A bearing is provided upon a side of the erin 49, this bearing; consisting of a casting extension 118. having a plurality of npstanding bearings 119 between which are mounted two or more fingers 121 fast on a shaft 122 through the l'iearings. The. fingers have abutments 123 (Fig. 6) engaging the *asting extension 118 under the action of a. rpring 124 fixed to the shaft 122 and to the casting extension. The spring normally holds the shaft in position to press the abutments against the casting extension. Then the slug carrier is raise-d to receiving and discharging position, the tinge-rs move through suitable slots in the end of the receiving galley or magazine and push previously discharged slugs down this galley. Thereafter the slug, or slug group just printed is thrust endwise into the end of the receiving galley and upon the next down stroke of the slug carrier. the fingers ride back under this just received slug group, extending the spring until it may again return the tin-gers to normal position.

lli/hen the slug group has arrived at printing position. means independent of the slug feeding mechanism comes into action to hold it against the pressure of the platen. This means comprises two latches, or arms. 13 loosely pivoted on shaft #16. Each said latch or arm is provided with an abutment lug 132 adapted for engagement with and to drop behind fixed abutments 133 mounted ou the frame adjacent the guides 145. dien the slug groups arrive at printing position, these latches drop to behind the abutments into operative relation. After the printing operation, the arms r latches 131 are raised by two bell cranks 134 fast on a shaft 133 carried in the bearings 136 from the frame. Each bell crank has an end disposed beneath the end of its companion latch or arm 131 and a second end adapted for engagement by a tooth 137 upon a shaft 138 driven from the shaft ('37 by gears 139 and 141 on said shafts respectively. After the printing` impression is completed, rotation of shaft 138 lifts the bell crank and unlocks the carrier so that it may move to slug receiving position.

'l'he printing impression is taken as will now be described. The frame is provided with a front extension 151 and upon this is mounted the platen 152 and its carrier 153. The platen is caused to bring the paper against the type by two arms 154 pivote-d to a croi-s eccentric shaft 155 in the platen carrier 153 and two crank pins 150 upon crank disks 157on the-sha ft 138 in L-uitable bean-ii jfl 159 in the press frame. This shaft carriel a gear 101 meshing with a gear 102 on shaft ($7. The platen in its stroke swings down tiri-it to a vertical position and then is i'novcd l1n\\.';;.rtlly on the printing stroke. The platen carrier is provided with an under surface which flat from the front end :at 163 to a point 164 therebehind and from the point 104 is curved upwardly as indicated at 165. A cam slot 166 is provided in the tail 167 of the carrier and a roll 168 engages this slot and as the platen moves insures ii-rst the swinging and then the rectilinear movement of the platen already described. it being understood that the swinging of the platen is about the principal center of the shaft 155. ln the printing action, the paper to be printed of course placed upon the platen and a holding fly 171 pivoted at 172 in arms 173 extending down from the lower edge of the platen clamps the paper in place during the printing operation. The movei .i of the fly is governed by a pinion 17st or: the fly meshing with a gear 175 pivotcd in brackets 173 and fast to arm 176 carrying rollers 177 adapted to engage a bed surface 178 to cause the fly to clamp the paper in advance of the printing action and as a par of the downward swing of the platen to vertical position.

rl`he printing press shown on the drawing is equipped with both inking rolls and ribbon for printing. The ribbon. mcchani comprises a pair of vertical spool holdei" 179 for ribbon spools 181 see Fig. t3, there holders being each mounted in a socket li having an arm 183 carrying a guide rol 184A behind which the ribbon is arranged. the two guide rods acting to hold the portion of the ribbon between them in printing position. The guide rods are provided with bearings 185 at the top for the spool holders 179.

The ribbon is advanced as will now be described. The lower member of each spool holder is provided with a beveled pinion 1815 meshing with a similar pinion 188 upon a cross shaft 187 having bearing in the socket members. The socket members are carried upon the ends of rods 191 see Fig. l havingl bearings at 192 in the frame, springs 193 causing the rods to move back after the platen has carried the ribbon forward. A

lspring ratchet drum 194 is mounted on the end of .shaft 187 and is engaged by a pawl 195 on a collar 196 on the shaft. A cord 18S) is wound on drum 194 and under the aetion of the spring ratchet drum, winds up on the printing stroke. On the return stroke the pawl causes shaft 187 to turn with the drum as the cord unwinds and the ribbon is advanced.

The inking mechanism will now bc described see Fig. 10. An ink plate 201 mounted at 202 on. the top of the frame is held in adjusted position against a supply roll 203 by set screws 204 arranged at intervals beneath the plate and adapted to bring the plate into such contact with the roll 203 as will insure the desired feed of ink. A transfer roll 205 is mounted in two arms 208 fast upon a shaft 207 in the top of the frame. This shaft is provided with an arm 203 connected by a link 209 with a crank 211 upon a shaft 2.12. which shaft carries a gear 213 meshingwith a gear 214 on shaft 158.

An arm 215 see Figs. 5 and 10 forms a bell crank with the arm 208 and this arm is connected by a link 216 with an arm 217 loose on a trunnion 218 of roll 203. A pawl 219 engages a ratchet 221 on the roll to produce intermittent rotation of roll 203. 1n the ink feeding action the transfer roll 205 is swung up fron] the position shown in Fig. 10 into contact with the roll 203 and the roll 203 is then advanced to produce the ink feeding action. The mechanism for swinging up the transfer roll 205 consists in an arm 197 fast on the shaft 207 and engaging a crank pin 198 in a. crank 199 movable with a gear 200 in turn meshing with a gear 196 on shaft 212. The action is such that the roll 205 arrives at the proper instance to receive the charge of inl; from roll 203. The inking rolls are indicated at. 222, four such rolls being provided in the present instance.

These rolls are mounted in a vertical slide 223 see Fig. 10, and they receive ink vfrom rolls 224 and 225 mounted in the frame of the machine. Each of these last mentioned rolls is provided with a pinion 226-227 in turn meshing with a pinion 228 on a stub shaft 229. This pinion meshes with a gear 231 liked on the trunnions of a distributor roll 232, eachy gear meshing with gear 200. Two idle rolls 233 are provided to convey ink from roll 232 to the two rolls 2264227. Gear 200 is provided with a cam hub 234 in which is engaged a cam roll 235 en a lever 236 pivoted at 237 on the frame and having an end at 238 engaging in a groove 230 of a disk 241 on the end of the shaft or trunnion of roll 232. As the parts rotate this mechanism causes the roll 232 to have a longitudinal movement as well as a rotary one for the distribution of the ink. A similar motion is given the rolls 224 and 22?. Their trunnions are mounted in a head 242 at 243. This head is swung about its pivot 244 by a link or lever 245 pivoted at 246 on the frame and engaging the end of roll 232.

The slides 223 reciprocate upon vertical guides 251 having cam faces 252 at their tops see Fig. 6. The rolls are mounted in the slides in spring bearings indicated at 253, scc Fig. 4 and the rolls engaging the cams are swung out against the pressure of the springs and ride down over the surface of the slides beneath the cam and across the face of the type. Two links 261 extend down over the slides and are connected to arms 262 ou shaft 64 see Fig. 5. One of said arms 262 is connected by a link 263 with an actufitzlijg" icvcr 2.6i pivoted ai on the frame and having a cam roll 266 engaging in a cam groove 267 of cam 268 on shaft 158.

The press is started into actuation through any suitable means for energizing the motor. it may be stopped quickly by a foot lever 271 pivoted at 272 and carrying a brake member 3 for engaging a ily wheel 274 on shaft 275 carrying a gear 276 meshing with a gear 277 on shaft 138. A spring 278 pulls the manipulative end of the lever upwardlv (viewing Fig. 5) and against a stop 279. This stop and the insulated member 281 are preferably in the circuit for energizing the motor and the application of the brake therefore cuts oii the power as Well. Prevention against thcl starting of the press again upon release of the lever is insured by the use of the usual starting rheostat..

in the press shown on the drawing and cinbodjyfing my present invention, means are j o'fded for permitting action of the press i.. .thont printing and also without the feeding ot' the slugs. 1t has been mentioned that izi't through the platen carrier is an eccentric one and when the parts are in noniai position the eccentric portion is arranged upon the side of the platen adjacent the type as indicated in Fig. 6. The parts ic locked in this position hy spring pins receiving in a yoke 292 pivoted about 'n axis ot' the eccentric shaft. Cross -..i3 entend through these pins and n rocking arms 294 at each end of shaft and connected by a handle 295. laen this handle is pulled to the left (viewing Fig. 4) cam surfaces 296 see Fig. 7 on the rocking .members 294 lift the pins and permit the eccentric to he swung back so that upon the forward stroke of the platen contact with the type does not result. This action interruiiits the slug feeding. An arm 301 mounted to rotate with the yoke when the yoke is swung to move the eccentric. This arm is adapted to engage a lever 302 pivoted :it 303 on the frame and engaged with a rod 304 slidnble in l'earings 305 and 306 a ri anged on the frame. The rod 304 carries an arm 307 engaging a clutch member 308 on shaft 103 so that when the platen is swung around to non-iirinting position the chain of slug ieed mechanism is interrupted.

The slugs are provided preferably in groups and to facilitate the feeding thereof l have shown in 14 a slug group arranged a single unit. The individual slugs or linotypes are encased in a band 315 of sheet metal having its ends interlocked ai. 316 or otherwise suitably secured together.

it is thought that the invention and many if its attendant advantages will be understood from the foregoing description, and it will he apparent that various changes maiY he made in the forni. construction and arrangement oi' the parts without e'leparting troni the spirit and scope of the invention or sacrificing all of its material advantages. the form hereinbefote described being merely a preferred embodiment thereof.
