Specification of Letters Patent. Patented A g. 28 1917.

Application filed June 14, 1915, Serial No. 34,105. Renewed July 16, 1917. Serial No. 180,957.

To all whom it may concern:

Be it known thatI, CHARLES M. MEAD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Flat-Bed Multiple Printing- Press, of which the following is a specifica- 7 different size and makeup, and for taking the web or webs from rolls and delivering the rinted impressions in separate sheets in pre etermined order, all of which features are embodied in a compact mechanism which automatically operates in a continuous manner.

The invention further comprehends new and novel features for cutting the web, for tensioning the web between the paper roll and the type-bed impression mechanism, for distributing the ink, for registering the impressions from successive forms and platens in multi-color work, for producing and releasing the impressions and for making perfor-ations in the printed web to register with the forms. l

The invention is regarded as broadly new and pioneer in the direct straight line reciprocating motion of the operating parts for producing the impressions, the'cla nping of the web while the cutting mechanism is operative, the double throw of the ratchet feed wheels, the means for alinement of the delivery belts, the means for simultaneously releasin the im ression mechanism, and the means or equa izing the stress and strains than the embodiment shown.

ruple construction having four type beds and four platens. The invention is adapted to a variety of Work, and its features are applicable in constructing multiple type beds and platen presses of greater capacity It is understood that parts maybe changed in arrangement and connection Without .departing from the invention, therefore no limitation is made to the precise construction shown.

Objects of the invention are to provide a flat bed quadruple printing press which will. meet a wide demand, being endless in its variety and combination of work, cheap to operate, great in speed and simple in construction, employingno curved plates, d0- ing all the printing from type, printing two colors on both sides of the sheet at once, printing two colors on two sheets at the same time, printing four different jobs at once on different colored paper in different colored ink and different in size and make-up. i

The press is particularly adapted for the rapid printing of laundry lists, bread wrappers, butter wrappers and dodgers, all of which different jobs can be printed at the same tlme.

An object is to print four jobs at once on 'paper taken from rolls with no stops and everything automatic. I

An object is to provide a press doing a maximized variety of work in minimized time and with a minimized number and complioaticns of parts. Y

,The accompanying drawings which are more or less diagrammatic in character illustrate the invention.

The press frame 1, having side frames 2, 3, and lateral braces 4, 5, 6, supports the various operative parts and devices including the web roll mechanisms, perforating mechanisms, and web adjusting mechanisms vhereinafter described; and also impression devices 7, 8, 9, 10, web drawing mechanisms 11, and web severing mechanism 12.

The impression devices comprise two sets A, A of platens fixed to the frame 1 of the press and two sets B, B of t e beds mounted respectively on carriages C.

In the form shown in Figs. 1-23 the platens all face in one direction and the type beds face in the other direction and are opposed to their respective platens; one

etweenthe carriages.

In the form shown in Fig. 24' both sets of platens are arranged between the type-beds and their carriages. p

The carriages in addition to carrying the type beds also carry the inking mechanism omitted from Fig. 24 and. hereinafter described for inking the type in a well-known manner during the operation of the press.

Each web roll mechanism consists of a roll arbors13 mounted in open bearings 14, a weighted lever 15 pivoted to the press frame, and a brake arm 16 pivoted on'the weighted lever and engaging the roll arbor. The brake serves as a retarding means forthe roll and a tensioning means for. its respective web prior to and during-the operation of the impression mechanism. Lateral adjustment of the roll arbor is secured by apivoted lever 17 having a swivel yoke 18 engaging with the arbor and a clamp 19 to secure the lever to bar 20 when adjusted. I

. Additional tensioning means for the re- 'spective webs priorto receiving the impressions, comprise take-up rollers 21, 22, 23, 24, mounted respectively on pivoted frames 25, .26, 27, 28, which are yieldingly supported by coiled'springs 29, 30, respectively connecting the roller! frames to lugs 31, 32

projecting from the press frame.

The carriages C, C and the mechanism carried thereby together with the web-drawingmech-anism and the web-severing mech-' anism-are all actuated from a common source of power,- and the shafts are journaled in bearings on the frame 1. V

The power shaft 33 extends across the frame and is mounted in. journals 34 on frame 1, and it carries on one side of they frame a momentum or balance wheel-35, and

fast and: loose pulleys 3Q, 37 respectively.

Bearing 123 is pivoted to the 'frame'by pivot .123 and may be turned down for removal Transmitting roller 119 is rotatively and of the spreading. roller;

iaof

detachably secured in arms 117 by springs 124. Shaft 121 is provided with collars 125 between which extend guides 126 secured to the press-frame and obliquely disposed to impart a lateralmovement to the spreading roller coincident with its rotary motion and the reciprocating movement of the form carrier. Similar guides 127 perform a similar function;

Springs 128 interposed between swing arms 117 and the type-bed normally hold roller 119 in contact with the master ink roller. As the form carriers approach the end of their rearward stroke, plungers 129 strike arms 117 in opposition to springs 128, and thereby force the transmitting roller against the delivery roller 119; the yielding stops 129 being extended by springs 130 disposed between supports 131 and collars 132 actuate swing arms 117 to yieldingly press roller 119 into contact with delivery roller 116. The collars 132 are adjusted by cotter pins 133 in said rods. Roller 116 is actuated by ratchet 134 and pawl 135 pivoted to levers 136 which alternately contact with opposite ends of the tappet arm 137 fixed to frame 3, and is thereby actuated to turn roller 116 a part of a revolution. The ink is taken from the master roller to the form (not shown) by rollers 114 which are mount ed in rockers 138 pivoted to sprin -actuated rods 139, the rollers 114 taking their motion from the tracks 111 while inking the forms, and from the master roller while in contact therewith. Beds 139 slide in bracket supports 140 which form a part of verticallyreciprocating frames 141; said frames 141 consisting of parallel rods 142 sliding in guides 143 on the form carriers, rods 142 being connected by top plates 144 and supports-140. Clamps 145 hold supports 140 in the desired position.

Triangular oscillating links 146 are pivoted at one angle by pivots 146 to the side frames 2, 3. A lower angle of said link is connected through pivot 147 to connecting rods 147 that are pivotally connected at their upper ends to top plates or brackets 144 fastened to the upper part of the reciprocating frames 141. Connecting rods 148 and 149 are co-axially pivoted to the form-carrier98, their opposite endsbeing pivoted respectively to pivots 148, 149 of the oscillating links,-and convert the horizontal reciprocal movement of the form-carrier into the vertical reciprocating movement of the frame 141.

As the carriers 98, 97 are operated to move the type-beds into the imprinting position, the rods 148, 149 will actuate through oscillating links 146 the connecting rods 147, thereby moving the reciprocating frames 141 upward, and causing the rollers 114 to engage with the master ink-rollers 110; As the carriers 98, 97 move in the opposite direction the inking rollers 114 will be moved over the type.

A means for adjusting the platens to secure a perfect impression (see Fig. 16) consists of threaded bolts 150 swiveled to the platens and extending through correspondingly threaded lugs 151 on braces 6. Lock nuts 152 on the bolts hold the platens in the adjusted position.

For determining the paths of the webs through the press, various rollers are provided, certain of the rollers serving as a guiding means for the webs, others to take up the slack, to cotiperate with the perforators, to draw and advance the webs in accordance with the impressions, to adjust the webs between successive impressions and secure registration in color work, to adjust the webs in accordance with the severing mechanism, and to deliver the severed sheets upon trays for convenient removal.

The threading of the press for printing simultaneously four different webs with the same or different impressions, illustrated in Fig. 4, is as tollows:

The web 6 istaken from a paper roll a and threaded consecutively over guide roller 153, undertake-up roller 21, over guide rollers 154, thence over perforating roller 82, thence over guide-roller 155, thence over platen 105, thence under guide rollers 156, over guide rollers 157, thence over adjusting roller 158, thence between web-drawing rollers 159, 160, thence between web-drawing rollers 160. 161, thence over a second adjusting roller 162, thence between feed rollers 163, thence between the shearing blades 164, 165 of the'severing mechanism 12,thence between delivery rollers 166, 167, thence to the delivery tray 168.

The threading of; the web to print each side in two colors is shown in Fig. 11, and

' .is described as follows:

The web p'is taken from the roll 9 and is T threadedconsecutively under take-up roller 22, over guide roller 169, perforating roller 83, platen 106 under guide roller 200, over adjusting roller 93, over perforating roller 85, platen 108 under guide rollers 193, thence under adjusting roller 94, over guide roller 17 9, thence over platen 107, thence over guide roller 178, thence over adjusting roller 84,- thence over guide roller 199, thence over platen 105, thence over roller-S155, 82, thence adjusting roller 162, thence between feed rollers 163 to the severing mechanism 12.

The threading of the webs to print one series of sheets on each sideand to print simultaneously therewith two additional series of sheets is shown in Fig. 12 and is described as follows:

The web 8 is taken from a paper roll 22 and is threaded consecutively under takeup roller 22, over guide roller 169, perforating roller 83, thence over platen 106, thence under guide roller 1,70, thence under adjusting roller 84, thence under guide roller,199, thence over platen 105, thence over rollers 155, 82, adjusting roller 158, thence between Web-drawing rollers 159, 160, 161, adjusting one adjusting mechanism asshown 1n Fi t. 13, 14, 15 will be describedft, Web adjusting roller 181 is carried by a U -fraine 2.01 which slides "in' the guides, 202 on framesi2, 3, the frame 201 having racks 203 engaged hy spur wheels 5 204, 205. A shaft 206 is journaled inthe press frame and has, an operating handle 207 Spungears 204:, 205 are fixed. to the shaft 206 in opposed relation to guides202,

the gear 204 being radially corrugated to;

A threaded sleeve, 209 is riveted or otherwise fixed to shaft 206, and a locking member 210 formed as a winged nut is correspondingly threaded and is screwed thereon and when rotated in engage with a correspondingly corrugated plate 208 fixed to' frame 1.

one direction will move the shaft 206 and Q the gear 204" axially lto causethe corrugations to interlock with. plate 208; thus locking the shaft to the frame 2 and holding the U-frame 201 and the web adjusting roller in fixed relationto the frame 2.

When locking member 210 is," rotated in the otherdirection, the, shaft 206 may be rotated to adjust the frame 201 and roller 181 carried. thereby, thus, to adjust the web to practically bring the printed surface into proper'relation to the severing or cutting mechanism. I

When the web-adjusting roller 181 has been. adjusted an additional or fine adjustment of the web may be made by raising or lowering the secondary web-adjusting roller 185 which is carried by brackets 211. This may be made as a final adjustment of the web between the paper roll and the webover adjusting roller 158, thence between drawing rollers.

web-drawing rollers 159, 160, thence be- Hangers 211 slide in guides 212 fixed to tween web-drawing rollers 160, 161, over the side frames 2, 3, and have racks 213, the

hangers being actuated by spur-gears 214 mounted on shafts 215 and engaging the racks 213. The shafts are rotated by hanthe web or webs in unison, the webs are fed between fixed shearing blades 165, 187 on the press frame and movable shearing blades 164, 188.

Pivotal shafts 220 journaled in the pressframes, side levers 221 and pivot rods 222 on which the shearing blades 164, 188 are pivotally mounted from rectangular frames that are actuated in unison by cam rods 223 which are provided at their free ends with rollers 224 operated by cam wheels 225 on shaft 64.

The gear transmission is such that the shaft 64 rotates in unison with and at the same speed as crank shafts 43 which give movement to the form-carriers and their respective type-beds, and the movable shear ing blades are operated thereby to sever the web at the proper time.

Adjacent the fixed shearing blades are I guides 226 against which the ends of the edges of the movable blades are yieldingly held by action of the springs 229; said movable blades having arms 227 and the side levers 221 having lugs 228 with springs 229 connecting said lugs and arms to thus hold the cutting edges of the movable shearing blades in position to cotiperate with the edges of the fixed cutting blades respectively.

The means for holding the webs taut while being cut comprises presser bars 230, each having guide pins 231 fixed thereto, one at each end, said pins extending upward into stirrups 232, which swing upon the rods 222. The guide pins 231 extend downwardly into guiding sockets in the press-frame. Tables 233 extend beneath said nresser bars, which bars are pressed yieldingly thereon. by springs 234 interposed between the stirrups and the presser bars. The stirrups 232 lift the-presser bars when the movable shearing blades are in their uppermost position. I

At the end of, the web each sheet is sup-, ported while being out and isthen delivered by belts 235 riding upon rollers 166, 167, 189, 190. The rollers 167, 190 are formed with crowned surfaces 236, 237 to keep the belts in alinement. Tables 238, between the delivery rollers, support the delivery belts. The sheets are delivered successively as cut upon the delivery trays 168, 191, which are removably mounted upon the pressframe. A counter 239 actuated by the rod 240 registers the number of sheets printed. The trip 241 slides on the counter-actuating rod 240 and is actuated by a spring 242 interposed between trip 241 and washer 243, and thereby strikes the counter-lever 244 a yielding blow. Counter-actuating rod 240 is secured at one end to form carrier 97 and extends through a guide 245 on the pressframe and reciprocates with the form-care rier, thus actuating the counter at each im-- pression.

It is sometimes desirable to draw out for each impression a length of web much greater than is required at other times, and the press is provided with means for drawing out a maximum length. For this purpose a double-acting ratchet mechanism including two duplicate ratchet wheels 246, 24 7, operate duplicate sets of web-drawing mechanism 11 and feed-rollers 163; said ratchet mechanism imparting intermittent rotary motion thereto. The ratchet wheels are engaged by pawls248 pivoted upon ratchet- levers 249, 250; said pawls being actuated by springs 251.

The ratchet levers are pivoted to the shafts 252, 253 respectively, of wheels 247, 246. One ratchet mechanism is designed to give a primary stroke and the other asupplementary stroke to drive the web-drawing rollers. Levers 249, 250 are provided with guides 254 to which clamp plates 255, 256 are clamped. Connecting rods 257 are pivotally connected to clamp plates 256 and to crank 258 on shaft 57. Connecting rods 259 are pivotally connected to clamps 255 and to crank 260 011 shaft 58.

The primary stroke given the ratchet wheels by crank 258 may be varied by secur-.

ing the clamp-plates 256 in various positions upon guides 254 and increasing the stroke as the ratchet wheel shafts are approached. The intermittent revolution of the ratchet wheels thereby given may be supplemented b the crank 260 and clamp plates 255 which are adjusted in like manner. Normally the strokes of the two sets of ratchet levers overlap, causing an intermittent movement of the ratchet wheels and actuating the web-draw ing rollers which in turn advance the webs the required amount between successive impressions. I

Cranks 258, 260 rotate in unison and are set to actuate the ratchet wheels 246, 247 during 280 of a revolution of the wrist pins 45.

Crank 258 begins the operative stroke of ratchet levers 249 when the wrist-pins 45 have moved 40 from the imprinting position.

Crank 260 ends the operative stroke of ratchet levers 250 when wrist-pins 45 have It is thus seen that the rotation of the ratchet wheels may be extended over more than one-half of a revolution; that the feed will start slowly; will be gradually acceler- I ated and then reduced until again stationary,

' and the feed rollers and ratchet wheels will y 273 and links 275.

have a minimum of momentum when released by the actuating levers.

As a further means for positive and accurate feed each ratchet wheel is retarded and held by weighted friction pawls 261, 262; said awls being pivoted to bracket supports 263, and engaging the grooved rims 264; of the ratchet wheels: thereh serving as friction brakes and catches for determining intermittent advancement of the web.

Referring to Figs. 1, 2, 8, 4: and 5, one set of feed rollers will be described. The ratchet wheel 2&6 meshes with a pinion 265 on shaft 266 of welrdrawing roller 160; said shaft 266-being journaled in the press-frame,

thereby positively rotating roller 160. Roller 159 is mounted in swinging bearings 267 and has a gravity contact with roller 160. lollers 161, 17 5 are mounted respectively in swinging bearings 268, 289, and are held in vielding contact with roller 160 by springs 270. 271.

The, pressframe extensions 272 carry sliding bolts273 adjusted by knurled nuts 274, and the swinging bearings 268, 269, have pivoted thereto links 275; the springs 270, 271 being connected to adjusting bolts Web-drawing rollers 159, 160, 161, 175 are driven in unison by gear- wheels 276, 277, 278, 279 mounted on their respective shafts.-

Motion is transmitted from shaft 266 to feed rollers 163 as follows:

Rollers 163 are actuated by pinions280, 281 mounted on their respective shafts. Pinion 280 is driven by an idler pinion 282 carried by a swinging bracket 283, pivoted to shaft 266 and meshing with a spur wheel 284 hn shaft 266. In like manner the lower ratchetwheel 247 actuates a similar Set of welrdrawing and feed rollers.

Shafts 57, 58 may be thrown into gear, by clutches, not shown, controlled by clutchlevers 284i, 285' respectively, and therefore, said shafts and their cranks 258, 260 may be independently or jointly actuated to operate the ratchet-wheels which thereby intermittently draw the webs during each reciprocating movement of the impression mechanism.

The rock-shafts 286 iournaled in form carrier 98, and rock-shafts 287 journaled in form-carrier 97 are normally inactive. Rock-shafts 286 have arms 288 and cranks 289, said cranks 289 serving as pivot connections for pitmen 95. Rock-shafts 287 have arms 290 and cranks 291, said cranks 291 serving as pivots for'connecting rods 96. -The rock arms 288, 290 are connected by links 292, 293 which operate the shaft in unison, The vertically extending link 292 has pivoted thereto a link 294, the oppositeend of link 294: being pivoted to lever 295 which in turn is pivoted to the formcarrier 97.

A notched sector frame 296 extends from the form-carrier and engages and holds lever 295 in operative and inoperative positions. Shifting the lever 295 will change the position of the eccentric cranks 289, 291, with reference to the form-carriers sufficiently to prevent the type-beds in their reciprocating movement from carrying the type against the platens or the web that may be extended over the same. Lever 295 is held in engagement with sector frame 296 by a plate 297 which in turn is yieldingly held in position by springs 298 interposed between the plate 297 and the heads 289 of supporting bolts 300 which are fixed to the sector frame and pass through the plate.

To transmit motion from shaft 55 to shafts 76 intermediate sprocket shafts 74; are employed and are intermediately supported by radius links 301, which are pivoted to the shafts and maintain a constant distance between the various sprocketwheels carried by the shafts 55, 74:, 76, the

shafts 74 having an arcuate path of movement in accordance with the reciprocating movement of the form-carriers. I thus provide a printing press with sprocket chains and sprocket Wheels to receive power from the main driving shaft and. to carry power to the master ink rollers. The links, the shafts and the sprocket Wheels and chains thereon constitute a jointed motion device adapted to contract and elongate at the forward and backward movement of the type bearing carriages, and thus the master rollers are kept turning uniformly with the speed of the machine.

The speed of rotation for the inking devices is preferably reduced and the speed of rotation of the delivery rollers which take the severed sheets from the cutter is increased by suitable transmission gearing. The rotation of the cams operating the shearing blades are timed in accordance with the rotation of the gear-wheels which actuate the form-carriers carrying the type beds so that the shearing blades shall sever the webs at the instant of impression.

From the foregoing it may be seen that each web as it leaves the rolls is subjected to suitable tensioning from the tensioning devices, and that various adjustments are provided to effect the proper registration of the impressions, the accurate alinement of the perforation devices, and the cutting and final disposition of the printed web into piles of sheets on the delivery trays.

Adjustment of each operative device may be effected without disturbing the other adjusting devices and the press when once put in operation will automatically continue to perform its several functions so long as the 'power shaft is drivenand the paper rolls are not exhausted.

In order that each form-carrier may operate its type-beds with distinct and positive pressure contact at the instant of impression the parts are so arranged that the axes of the cranks 289, 291 lie in horizontal planes that are lower than the planes, re spectively, in which the actuating crank pins 45 on the driving wheels 42 lie; and the pitmen 95 have pivot connections 302 respectively with connecting rods 96. This arrangement will cause the thrust and stresses at the moment of impression to be distributed equally among the four typebeds and their opposed platens, and pre- 1 vents distortion of the web or webs, an es pecial advantage in multicolor work, where ad ustment 1s des1red between successive platens.

deck printing presses is made possible; the

action being direct instead of circular and the paths of the moving parts thus being minimized; and furthermore, the deflection ofthe inking rollers from a straight path relative to the carrier is minimized'and the necessity of long springs to accommodate such deflection is done away with.

I have thereforeproduced a new machine comprising a printing press frame, a carriage or amultiple of carrlages moving perfectly parallel tothe platens and carrying a multiple of typebeds, distributing rollers, vibrators, master rollers, ink fountains and ink carrying rollers, and thus secure a higher speed of operation.

In the compactsimplified form shown somewhat diagrammatically in Fig. 24, the sides of press-frame 321, are longitudinally contracted and the type-form carriers 322 reciprocate upon the frame 321 in opposite directions; the movement of the form-car- -proach the printing position as they apriers being toward each other The formcarrlers are provided with trunnion wheels 323 which travel upon the press-frame 321,

A train of gear wheels actuates various shafts in unison for operating the various reciprocating and intermittently rotating operative parts of the printing press. Gear wheels 324 on shafts 325 are provided with wrist-pins 326. The form carriers have -journaled therein shafts 327, and pitmen 328 connect the wrist-pins 326 and shafts 327, the arrangement being such that the form-carriers are brought simultaneously into the printing position, and the draft and strains upon the press-frame incident to the pressure of the type-forms against the platens, are equalized.

Shafts 329, 330 rotate in unison with shafts 325 and are provided with cranks 331,

respectively. Cranks 331 actuate swinging ratchet arms 333. 334, 335, 336, and cranks 332 actuate swinging ratchet arms 337, 338, 339, 340.

Cranks 331, comprising a double throw crank on each end of the shaft 329 are set to actuate the ratchet arms 333, 334, 335, 336 through connecting rods 341, 342, 343, 344, respectively, while the wrist-pins 326 are approaching the printing position and are revolving through the arm ww. Cranks 332 consisting ofdouble throw cranks on opposite ends of shaft 330, are set to actuate the ratchet arms 337, 338, 339, 340, through connecting rods 345, 346, 347, 348 respectively, while the wrist-pins are revolving through the are 317 Ratchet arms 333,, 337 actuate ratchet wheel 349 which in turn drives the web drawing roller 350. Ratchet arms 334, 338 actuate ratchet wheel 351, which in turn drives the web drawing roller 352. Ratchetarms 335, 339 actuate ratchet wheel 353, which in turn drives the web drawing roller 354. Ratchet arms 336, 340 actuate ratchet wheel 355 which in turn drives the web drawing roller 356. -The cranks 331, 332 are set so that the web drawing rollers 350,

352, 3.54, 356 are inactive at the moment of impression. I

The webs E, F, G, H, indicated by dash lines, are out into sheets by the severing mechanism 357 and pass therefrom respec tively, between delivery belts 358, 359, 360, 361, which are driven by delivery'rollers 362, 363, 364, 365;

Each of the four sets of delivery belts and rollers are mounted on one of the swinging frames 366, 367, 368, 369. The swinging frames being pivoted respectively to the shafts 370, 371, 372, 373, the delivery of the sheets from the four webs may be made sepsheets in a single stack.

In this construction the press-frame may be'made much heavier at the center as the arately or they may be combined to pile the the platens,

pull against the platens is toward the center of the machine, and the number of web guiding rollers required is minimized.
