My pressis of the bed and cylin der type. The invention' includes means for reciprocating the bed whereby it may be moved rapidly and brought gradually'to a stop and gradually resume movement in the opposite direction. Another. feature of ythe invention comprises the means for moving the platen into and out of coac'tion with the type bed. The paper gripping means on the platen and the operating mechanism to effect the delivery of the paper on a second .rotation of the platen is also comprised with- Y The invention likewisein ythis invention.

includes an efficient means for working up A the ink'and delivering it to the type form. Accessibility of the various parts and ease of adjustment thereof are characteristics of the mechanism of this invention.

' The invention is hereinafter lmore fullyvdescribed in connection withfthe drawings illustrating a preferred embodiment thereof, and the essential novel characteristics are summarized in the claims. j

Referring to lj"ig.i3l,.myd-invention com; prises the following generalf features which: will later be --described more in detail,

ment ofthe` mechanism for turning fdowng the platen, being subst'antially across sec tion onthe'line 11212 offFig. '2;V Fig. 13 is 1 a perspective of a 'latchfor the-paper gripnamely,l the lsupporting frame 1'; a reciproeating type bedl 2O :slidably mounted onJthe upper portion ofV the frame; a driving mechanism for the type bed ;v an inking system 8() for inking thetype;` an'impresf sion platen 140 ,provided with grippers, and# means whereby it is moved into and out of co-action with thebed; a paper support vor mechanism at 295 feed' table 320 eJecting and adelivery table ,350.

As lthe paper.- is ,fed forwardly, 'a l `sheet at a time by hand (or automatically by means not shown), along the table 320, itis gripped i by grippers carried by -the platen roller 140 while the type bed'2()4 is at the left `hand end. of the' machine (Fig. 11),.-t`he platen in this ligure rotatingina righthand direcf` tion.V This carries "the .sheet down around the platen and between itand the bed i which is concurrently .moved toward the. right andv then, after printingV is completed,

the grippers 4carryythe.sheet around the top i i of the roller and dischargeit wherel it' passes to the delivery table350, as the plat-en starts on; its A.second .st'roke. During this 'second stroke,'the platenv is raised-out of contact withthegbedand the bed is -returned idly beneath the platen to the lefthand pol sition, the 'bed being inkedduring such movement.v Accordingly, the ,printing .is l ef-f fected lat-,everyalternate rotation of Vthe platen which` corresponds to each movement in the. corresponding direction of the y bed, i the paper being delivered andthe bed `re-` turned' andre'einkedon the other alternata;`

The framezl ,of the machine shown, comv f prises a suitable.. horizontal bed 2, and alv suitable means for supportingiu the means shown being af leg framej, bolted to they,

`and a horizontal outwardly., entendingflanges 5 and 6i supporting the standards forthe platen .and the inking mechanism,

' "ened'by websasindioated at The type bedis a horizontal member having a flat top plate 20 and severallongfid lo 14 rising secure-d to the `walls" 7 and i8 of the frame,

being connected to the lower Thebed has a vcentral longitudinal openingb 10- lor the driving, connections and is s 'ta ly stidtheser anges tudinal downwardly extending webs 21 (four Vbeing shown) which are supported by roll frames resting on the frame bed. Each roll frainexconiprises a series. of 1 rolls 23 yourdr naled between longitudinal bars124, the rolls resting on bed.`l f f vDepending from` the underside of the type bed20 is-'a vertical housing 30 in which is ai vertically slidableblock 31, see Figs. 5

and 10.5 This blockis connected by a pivot VpinA lwith. a driving sprocket chain 32,

mounted on two sprocketiwheels 34' and '85 and having upper and; lower horizontal reaches as shown. When 'the vpivot pin 36 of the lblock is traveling on either of the horizontal reaches, the type bed, is moved at a corresponding speed` .in the direction or' travelt As thelink carryingthe pin starts traveling around the outer portion of the periphery of either : wheel 34 or 35, the block '3l slides alongvthe guideway 30 and toward the centerithereoifand the speedl of movement ofl thehed diminishes until itis stopped when the ,pin is in a'honizontal planethrough the;A axes of the wheels -34 and Inf the vnext quadrant of fiiioxvemeng thebed starts f in the opposite direction and :gradually ins `creases its speed until-it reaches its full`4 speed when` the pin ,comes` to the bottom;

ol the wheel S35-or' the topof the wheel 34. The"V housing 30 referred to, Vmay convenientlyfbe a casting having a'horizontal flange 37 through which .it is #bolted to they under side'l of fthe' type bed and havingl an upright parallelsided recess 38 withrabbeted edges overhung by gibs 39 fastened to the face of the casting. Theblock Slwhich lies within the guideway has outward: flanges 4() behind the gibs and "hasits forward portion' lying lbetween the gibsandabutting a yoke 42 Vcon-iv stituti'ng a head onf'the pivot pin S36. The pivot pin is `journalled in the block, the head 42 is I a channel-shaped member` of; substanv. tiall'y the same length as a link of the' sprocket chain and'it takes the plane of'a link', carrying-pinsil pivotally' connecting thefadjacent chainlinks 44 and 45.

f outer ends.

The sprocket 35 referred to, which is the idler, is preferably adjustably mounted. To effect this, l mount it loosely on the eccentric end 51 ol a shaft 50 (Fig. 11) which is Y j ournaled in bearings 52 extending downwardly from the 'frame bed 2. A suitable.

lever 54 on the shaft' furnishes `means for turning it and the screw4 55, passing through 'a' slot 2) .in the lever, enables it to be locked in'adjusted position. By this means,

I may maintain the chain always taut, to

eilect an accurate drive of the type bed.

The sprocket wheel 34 vis tliedriving member for the chain described. Torotatethis' wheel, it is'con-venient to secure it. tightly on the shaft 59 which is secured to the driv ing wheel 60 driven in any convenient man# l ner. As sho-wn in Figs. l1, 4 rand v5, l have. connected the wheel 60 by a'sprocket chain,

61 with a sprocket pinion 62'on the shaft- 63 mounted in brackets. 64 andy carried by the frame legs. On this shalt (i3 is a belt pulley 65. A belt'G is shown as running over this to a driving pulley 67 on the motor suitably mounted between the frame legs;

It will be seen from the construction de#V scribed, .that the driving `mechanism `causes a given direction as indicated by the arrows in Figs. 1, 2 and l/Vhen the drivingblock 31 is traveling the lower krea-cli oi this chain,

the type bed is moving toward the Vright hand,

in Fig. 1 yand is effecting-.itsprinting operation. When the block is traveling the upper reach ofthe chain, the type bed is moving toward the left in Fig. 1, which movement is idle except that the type is being inked theL sprocket chain to travel continuously in ioo To prevent jar as theftype bed' comes ino v nientarily to rest, .intermediate its alternateV movement, f1 provide the dash pot construction shown in Fig. 5. Extending from the opposite edges oi" the housing BD which depends from the ytype bed are twohorizontal I rods 70 which carry plungers 71 onY their Carried by the -llramey bed in alignment with these plungers are dash pot j cylinders 73 eachof which has ears 74v (Fig.Y r4)"byY which it is secured to the 'frame bed.

The dash pot cylinder is entirely open at its inner eiidand chamfered at this end asV` 'shown at 75 to enable't-he rready entrance' of vthe plunger. At the oppositeend of the i cylinder is an opening 76, across the inner 'lace of which extends alilexible valve sheet f Y 77. A pet cock 78 leads from' the cylinder in front 'of the valve sheet.

As the type bed is approachingeither end of its movementythe corresponding piston 71 enters the adjacent dash pot cylinder, thereby compressing the air-therein, closing the check valve 77'and forcing the-air out through the pet cock. Any desired amount of retardation may be ellected in varying` the amount of closure of thepet cock. Whenvthe bed has come to rest, the `return move-r ment is free .from theV dash pot retardation,

as thelcheck valve opens onthis movement and admits air to `the vcylinder behind the piston. The means described is accordingly enabled to insure the inertiaof the bed being properly taken up as'the bed comes to momentary rest, thus preventing jar on the mechanism or undue -wear on'the parts, withwith the'y resumption of" out interfering movement in the opposite direction.

The inking `mechanism v comprising a fountain and ductor,'distributor and form rolls is best shown in Figs. 3, 7 and 8. The

frame of the inking mechanism consists of two upright plates 81 and 82 mounted on theV frame bed, these plates being braced by a crossniember 83 which forms part of the ink fountain, and frame'brackets 88 and 89 .pivotally connected with these plates byv means of the shaft of the fountain roll 87. This cross member carries spring plates 85 pressed by abutting screws 86. against the fountain roll `87 `journaledginy'the frame plates, the ink lying `inthe trough-shaped space between the spring-plates and fountain roll. 90 indicates a ductor roll lmounted in' movable arms 91 and adapted to carrythe ink from the fountain roll to'atransfer roll 93 mounted inthe bars 88 and 89. 94 indicates a composition roll receiving 'the ink from the` after described. Thislink ,operates an armj 101 carrying a paw1x102v adapted to engage the teeth of'a ratchet wheel 103 mounted on the shaft carrying the fountains' roll. The movement of the link issuflicient to` carry the pawl over several of the ratchet teeth. I

have shown an adjustable vplate 105 having' a,v flange 106 overhanging the .teethto limit the and. the mechanism *for operating it withV f V particular reference to Figs. 2,16, 7 8 and .115 t number of teeth to be engaged by lthe pawls. This plate has an arcuate slot 107 through which a set screYs7 108 passes into the frame plate 82. Byloosening'this screw the plate may be swung` and the flange i106 thus `brought closerto or farther from the nose of the pawl 102. When the nose strikes the flange it rides up on-it and the rest ofits travel in idle direction is free from the ratchet teeth and on the return stroke it operates only onthe -teeth V,left available after the pawl clears the flange.

The same link-100 mayalso loperatethev ductor roll. As shown the arms 91 carrying the ductor roll are rigid on ashaft'110 on which is secured a rock arm 111 connected by a linkY 112 with the "link 100.v

described.`

Y The transfer roll 93.. and. the, reciprocating distributor 95 are rotated by means of gear-p-` ing connected with the type bed; thus there is mounted on the type'beda rack120wh-ic'h meshes with an idler 121 mounted on a stud `70 carried bythe frame platev 82.` This -idler meshes with the gear 121,3 rigidf'with thefre-A ciprocating roller,` 95,'y and'y this gear 123 meshes with an id-ler .124 whichfmeshes,with i the *gear 125 on thetransferroller .93; The .175 reciprocating distribut'or9-5 has on itsother end a crown camf127 Fig. :3,.having a figureH 1 8 groove intowhich extends a vpin 128 tcar` y ried by the frame member 81.A This causes v theroller'95 to reciprocate as it isrotate'd; 80 i itsshaft sliding freely-in'its bearings. yThe gear 123 is madeof extra'width sov that 'it 1 may reciprocate without losing itsmeshing engagement ,with the idlers 1 21and 124.r The type vor' printing member 130 .js .85 mounted in a suitable chase 1317on the type bed 2,0. Beyond this chase .is` a raised horizontal portion of the ty'pebed 133, the up-w per surface of which isinthe same horizontal plane of the printing faceQofthe 90 ,.twype. Accordingly the form rolls 96 and. 97 which'coact with the type'ifacealsocoact as the bed approaches itsextreme les. hand..

the .drum rotates this sheet of paper is carried/around with. it and `between `the platenA and-thetype *bed7 .the platen being lowered just after `:thepaper is gripped so asto cause the papery to beimpressed between the type vand platen. iIn the next rotation the paper is delivered and theiplaten 'is raisedout of 'l coaction with the typeV bed to-allowv the latter :to make its return stroke.

A" The mechanism' for. turning the leccentrically mounted shaft 145 to give theplaten its up and down movement is best shown in and 12. This shaft is connected by a rock Varm and adjustablelinkage system to be described,v withfa ber 148 which carries the platen.l On the inner end of thisv shaft 151 is Va rock arm 154 carrying a roller 155 which vcoacts with Vcams on the type bed under the influence army 150 andthrough the linkage turning of a spring 157 secured to an ari`n-158 con-' lnectedwith the shaft 151. These cams are desionated 160 and 4161 respectively. The

latter coacts with Vthe roller 155 as the-typeVVK bed comes to its left hand position in Fig. 2 and thereby shovesiip. on the rollenrocks the Vshaft 151,` swinging downwardly Y the the shaft 145'to lower the "platen into yactive scribed later,

lThe adjustabley linkagefreferred toi'between the shaft 145 and the rock arm 150.Y

is shown on a'large scale in Fig. 12. As there shown, and asalso appears -in Figs.

Y 2 and 9,- the end of the shaft 145 is square and Vhassecured to itan yarm 170 which has aslot1717 while loose on this shaft is another arm 172 having 1a pin -17 3 projecting loosely through the slot. The latter arm is connected by a link 174-withthe rockk arm 150.--V The link 174 is adjustable length' wise, andpone of the arms is adjustable with l referencev to the other by reason ofa screw and nut connection rbetween Vthe'two arms.

That is tosay, pivoted on the pin 173 is an eye.V .175 which vis av nut 17 7 occupying anotch in the arm between the flat-portion thereof and a curled over `portion 178 loosely'receiving the screw.l By these means the linkage'rconnecv rockarm 150. on a shaft 151 journaled in the frame mem The platen remains in Ithisposil ftion, being latched by-mecha'nism to be dei through the printing stroke Attlle end of that strokethe j cam 160 operatesto release the latch .mecha--v havingy a threaded V.shank 176 on tion betweennthe shaft y andthe yar1a1w150' 'may be adjustedto a nicety.

gripping the paper to'the platen, and releasing it to the delivery mechanism on the next stroke of -the platen, particularv reference being had to Figs. 3, '6,'r 7 and'9. f The paper gripping fingers' 2,10 are mounted onabar 211'which is carried byv a number of brackets 212 loosely embracing a. shaft 214 mounted in the end members 141 and 142 ofthe platen. The-fingers 210 project lbeyond the edge of thel bar 211 inpositionfto overlie the adjacent edge of the'platenl and may elastically press such edge when moved thereto by reason of springs 216'compressed between the bar and collars 218 tight on the shaft 214.'- On the lend of this shaft is a pinion 220 meshing With a segment gear 221 which serves to rock the shaft to cause the fingersto clamp the paper.' j

The segment' gear 221 is mounted on a Y rock shaft 223 journaled inthe drum. A

rock armf224 on thisV shaft within Vthe drum has attached to it'atension'spring225 angers are 'brought-intolclamping position atchored at its other end to a rod 226 mounted inthe other side of the Vdrum'. This spring thus tends to turn ythe bar v211 to carry the fingers out yof clamping position. These-finthe proper time by means of a roller 230 on the segment arm 221 engaging the cam 231 i Vextending around the shaft 145 and mounted between the hub 143 bearing on the frame plate 14,8.' This cam is accurately adjusted in position by reason of an Aadjustablepin 233 which has on its end an extension 234 connected by a link 235 with the cam.

The cam 231 is peculiarly formed, `as illustrated in Fig. 6. It has a flatportion 236 nearest'the axis which co-act-s with the roller 230 during about a third of a rotation, which corresponds to the upper' right hand portion; (Figs. 6 and 7) of the travel of the gripping fingers. When the roller ison this portion of the cam it is; nearest the axis and the fingers areheld away from the edge of the platen bythe spring 225, being in the position shown in Fig. 7. l Now just after the lingers reach their highest point as shown in Fig. 7, the'roller 230 rides over the shoulder of the` portion 237 ofV the cam of greatest radiusand this rocks the'segment againstthe action of the spring intoy its outermost position fto 'swing the fingers 210 down onto the platen edge to grip the paper.'

The .rollers 280 are fixed axis by :reason of being mounted on a ried in arms-282 and has o n its ends rollers 283 engagil g smooth cylindrical surfaces on the drum, The-arms y282 are mounted'on a movable frame consisting ofv twogbars285 hinged at 286 to the frame members v147v and 148 and connectedattheir oppositeends by a cross bar 288. yThis construction enables the Vrollers 28()` and otherpartsto be hereinafter vdescribed .carried bythis removable frame :to be swung idly, out of the way as indicated inbroken lines in Fig. 6, to lallow access to thel upper portion of the platen and thus to its interior. I Reverting to the. ejecting VVmechanism, the receiving support 29.0 consists of separated plates .spaced laterally out of `registration with the gripper lingers and carried by the curved sheet metal plate 291 mounted on a square bar 292 having trunnions 293 at its ends mounted in the framemembers 1.47 and 148. Rigidlly mounted, on the bar 292 are a pair of pla-tes 295 which provide bearings for the shafts of the delivery rolls; that is to say, the rolls 296,297 and 298 have shafts 300, 301 and-302 respectively, which On the shaft 300 is a pinion 303 meshing with an idler V304 which .meshes with a gear 3051 in the form of a ring secured -to the end of the platen, as shownin `Fig. 9. The idler 304 a stud carried by anarm 307 is imounted on rigidly mounted `on the square bar y292. The

pinion 303 on the shaft 300- also meshes with fan idler `308 which meshes with a pinion 309ontheshaft 302. The .squaregbar carries alsoadeilector plate 310 extending transverselybetween the rollers296 and298. It results from the above/described. c011- struction that all ofthe rolls of theejector mechanism vare continuouslyf revolved, lthe roller y 297 rotating- ,byg friction'al eoaction withthereller v`296 As :the paper being ejected' reaches the support 290Vv it` slides VVln the embodiment shown the)y thepaper is' fedl to the machine manually.

lt isplace'din-,a substantially'horizontal pile y fanned out, the topmost sheetsforward,as shown at A in Figs.V 12 and.7. Thisl pile rests on a substantially horizontally,.S11P" ported plate 320. This plate hasfdownwardly -flanged edge por-tions 321 vwhichjat Vtheir forward ends are. provided'` with notches 323 adapted to hook .over studs 324 carried by the frame members 147 and 148.

At its otherv end the plate is supported by r`struts.3.25 which are hinged at their upper ends to the p'late andjat their'l'ower endsto vears 3264 rising from the vframe bed 2,'A

To enable ready access tothe inling mech anismit ,is onlynecessary to; unhook the for;V ward end of the paper supportf-rom the supporting studs 324 andlswing the support longitudinally and.downwardly, lin which position it may Irest on `a vguard plate 323 secured to the frame bed Aand extending over and adapted to shield the -inling platen 1 33 of thetype'zbed.

rlhe forward yedge 329 ofthe paper table lies just in front ofthe cross bar 288 of the movable upper frame heretofore referred'to,

and the pile of paper lies on the plate 32() Y i and-also on the .cross bar 288.. Secured to the paper table is a side kguide plate 330 which is shown as adjustably held in place by bolts .331 extending through the side guide and occupying transverse slots 332 shown in broken lines' in Fig. 3 inthe paper table, the bolts having headsbelow the slots.-

Carried by the vframe barsV 285 Vand die rectly at the rear Aof lthe cross Ybar 288 isa supporting plate 335 `carriedby earsl 336 se;` cured to the bars 285. Above this plateis a guide plate V337 anchoredatone end toa cross rod- 338 and at vthe `rotheren'd toV a cross bar.339. v y f As the paper inthe pile vis shoved forwardly it passes between the: plates 335and 337 against a series .of stop fingers 340 car-y ried'by the ybar 339. The manually fedfsh-eet aan remains in this positioniintil the gripper fingers have iust passed it o n the gripping rota-tion fof the platen and thereupon these lingers swing downwardly very frapidly,un. der the yaction of the cam 2,31.. and thus pass cui" . position on the plate Y bolts 357 extending through slots in the'p'late `V`between the stopvfingers 340 and lower the edge ofthe paper below th-e stop fingersand grip iit between-the gripper fingers and the platen.: This gripping vaction is so rapid that it is effected notwithstanding al high I speed of rotation ofthe platen.V

The ,late 335 serves to deflect the manually fed' sheet upwardly so that it will al ways strike the stop fingers 340,'and it is immaterialat what stage of the rotation the sheet reaches this position, provided it liS-in this position whenthe gripping lingers wardly.

f During its passage aroundV the drinn, i the paper is held thereto'by vflexible bands 345-. anchored at one end to a cross rod 346 carried by the frame standards 147 and 4143 and the other end kept tautl by springs 347 secured to the strips'and anchored to arms v348 rigid on the rod 349 carried by the'franic members. l y s .l

After the sheet has been gripped and carried around the platen and printed a'nd'tlien ejected by kthe ejector mechanism.described, litl` passes to the left (Figs' 1 and 2) and falls `by gravity vonto the receiving t-able 350, which consists of a removable platecarried by the'fra'me bed. As shown thislplate has a downwardly extending forward flange 351 adapted to hookv over pins 352 and has side flanges 353l which are notched to rest on supporting pins 354. `This enables the device-Ito be readily removed when desired.

' The table carries four edge guides .for the sheet, whichare shown asfianged plates 355 and 356 which are clamped in adjustable As shown, ysuit-able provide means for adjustable positioning the side guides 355, while the front and'rear guides 356 have slots throughtheir horizontal flanges through which extend pins 358.` i

The tympan sheet for the platen `designated 360 is anchored at one end by an eccentrically mount-ed rod 361 which extends across the platen and is adaptedl to clamp the sheet against theinwardlyy thickened portion 362 of the drum shell. `This shaft has a squared end by which'a socket wrench may turn it to bind the tympan sheet, a ratchet lwheel 363 and pawl 364, Fig. 6, servingto hold it in locked position. The other end of the tympan sheet passes through a slot in the squared shaft`365 journaled in the platen and likewise having a squared projecting end for a socket wrench and having a ratchet wheel 366 with which a pawl 367 coacts. The squared end of either shaft is 'rendered accessible for 1 the application.` of asocket wrench bythe openings 369 in the frameplate 147 supportingthe` platen.V The tympan sheet is-kept `clean-by a brush V37() (Fig. 7) carried by a woodenbar'371 70 f mounted on a steel strip 372 secured at its*r ends to the framefmembers 147 and-148.

- I have' heretofore commented on the ready l n accessibility of the various parts of this ma-` chine. Access to the inkingfountain is obtained by simply unhooking the paper tablel 'andfoldinggitdownwardlyl Inspection of i y the. ink on thel inkingplaten 133 may be readily cbtaineol'by. raisingv the guard`328- I l which is pivotally mounted nearits` inner end. Access to the type bed, vfor positioning Vthe chase thereon may be had eitherfby removing the Vdelivery table orby' swinging it out of the way j Iv have shown one of ,the pins 352 holding this table asv shorter thanVv thel other oneso that the table may bere- Vleased from one pin by a slight vlongitudinal movement-.and then swung on the other as La hinge, v'tipping the table toward the vside of the machine.
