No..425,1199 filed March 16, 1923.'-

The paper guiding Aand controlling devices. i

of known construction Vfurther comprise ay paper pressure device or bail adapted to co-operatewitli the front upper side of the platen.y Said bail` is mounted from 'angular brackets 13 :which are ,secured by screws 14 to opposite end portions ofthe Yfront bar .1 ofthe carriage truck. Securedy to .thezupright portions ofthe brackets 13-'by headedl screws 15 are rearwardlyextending plates 16" which-are perforated -to receive a rod-or i'ock'shaftl' and 'provide bearings therefor. Said rock shaftis comprised in lcurednto-the.end portions vof the rock vshaft 17 inside the'plates 16 vand extending rear- .'onthe shaft 19v are a` plurality of pressure -rolls V22v which are, adjustable to desired positions along said shaft. The middle por sure roll devices 22 and 23 coi-operate with the face of the platen above the printing line and are maintained normally pressed operatively thereagainst by draw springs 24, one. at each side of the bail. The rear end of each spring is hooked over a screw 25 projecting laterally outward from the associate arm 18 near its rear. Said springs 2,4 extend forward and downward and their forward ends are anchored to screws 2G secui'ed to downward extensions 1o of the plates 1G. While normally maintaining the pressure roll device or bail in operative contact with the platen said springs permit Vsaid bail to be swung upward and forward away from the platen on its pivotal axis .17.

My invention comprises in the present 1nstance a paper deflector or apron 27 made preferably of sheet metal and curved to conform to the curvatuie of the platen. Said defiectoris arranged at the under side of the platen and is secured by screws 28 to blocks 29 which may vbear rotatively on the rock shaft 11, thus adapting the deflector to turn on the axis 13. Arms 30 fixed to the under side of the deflector or plate 27 at its rear and depending therefrom have coiled springs 31 hooked over ltheir notched lower end portions, said springs extending foi'- ward and vbeing anchored to the cross bar 7 'of the platen frame. Said springs 31 normally maintain the front portion of the deflector plate 27 in spring pressed contactive engagement with the platen ror the paper thereon. The front upper edge of said plate 27 is extended 'upward as vclose to the printing line yas is possible without interfering with the types, and said edge is found useful as a printing line indicator. The

'springs 31 cause a lightpr'essure of the frontl upper edge 4 portion of the defiector Vplate 27 against the platen. lt will beobserved that unlike the usual construction, the plate 27 is mounted and spring pressed independently of the niain feed roller 10 and the other paper feed and paper pressure devices. The deflector plate A27 is formed with openings or windows 'indicated at 32 through which the sectionsrof the feed rollers 10 and 10a 'protrude and contactively engage'with the platen. Means hereinafter described are emon its pivotal axis 11 away from the platen so as to provide an opening or throat indicated at 33 between the front edge portion of the de'fiector and the platen.

In addition to the guiding device or deflector plate 27, a supplementary guiding device is provided which is designed to facilitate the introduction of paper into the open throat and the front feeding of such paper. ,Said suppleinentaiy guiding device or deflector contrivance is preferably mounted on the bail member 17-23 and comprises a square rod or rock shaft 34 which is arranged forward of and parallel with the shaft 19. Said rock shaft is provided at its ends with pintles 35 which bear in openings in the bail arms' 18. Frictionally mounted on the rock shaft 34 are a plui'ality, four in the present instance, of paper guiding devices Vor fingers. Each finger 36 is made of sheet inetal and is generally triangular in shape, being bent to surround the shaft and so mounted thereon that it may be slid lengthwise to any desired position longitudinally of the platen. One face of the rock shaft 34 may be provided with a scale or other indicia to facilitate the adjustments of guide fingers 36. The guide fingers 86 are normally .maintained thrown off or away from the platen, as in Fig. 2 but key controlled means are provided for rocking the shaft 84 and throwing the fingers into co-opei'ative relationship with the platen as illustrated i-n Fig. 3. Said means may comprise a toothed collar or pinion 37 fitted over and secured to the left-hand end por tion of the rock shaft 34 as by screws 37a. The radial teeth of the pinion 37 constantly niesh with the teeth 38 of a gear sector 39 vhaving a 'hub portion 40 which bears vrotatively on the shaft 17 somewhat to the right of the left-hand arm 18. The sector 39 is formed with elongated slots indicated zit-.41 which receive the Shanks of headedscrews 42 that are threaded into a triangular plate 43. Said screws clamp the sectoral plate 39 'and the plate 43 together, and .coeoperate 'with the slots 41 to afford relative adjust ments of the parts 39 and 43. Integral with the plate 43 is a rearwardly extending finger 44 which is adapted to lengage with the left-hand end portion of the deflector plate 27, the upper 'edge of said plate being cut away to the left ofthe platen Vto provide a contact face 4.5. From Fig. 1 it will be `rseen that the finger 44 is offset leftwaiid so that its up and down plane of movement is to the left and clear of the platen. The plate 43 is of course perforated to fit over and bear on the shaft 17 in line with the perforation in the hub '40, and the two-part device 39, 43 is constantly spring pressed by "a coiled spring 46 Awhich is wound around the shaft 17 and has fone end hooked under the plate 43. The opposite or inner end portion of said spring fits loosely over the body portion of a collar 47 having a flange 48 which receives said screws 49 whereby the collar is fixed to the shaft 17. rEhe inner end of lthe spring 46 is bent out to fit into a hole 50 in said fiange. By loosening the screws 49, the flanged collar 47-48 may be rotated on the shaft 17 to vary the tension of the spring 46, Normally said spring maintains the member 39, 43 swung up into the Langage 2 position, the downward movement of said Amember onthe aXis 1,7 being determined by a key contrivancelneXtto bedescribed.

Said contrivance comprises a.l key for temporarily throwing the guide fingers 36 into:

place,jand .alsoyone for holdingf'or locking,

l shoulder screw which is threaded int-ol the outer face of the plate 43 near its upper end,the memberl thus being movably supported against the outer or left-hand face of-saidplate. VThe reararm 52 is provided with a key or butto-n 56 and the forward arm 53 likewise carries a key or button 57. The. downwardly kextending arm 54 is .formed with l a jvertically disposed slot `58 enlarged at its upper end tol provide a locking notch or shoulder 59 said slot 58 being en- .gagedby a. screw 60 projecting laterally from the left-hand arm or crank 18. The

lower end ofthe slot 58 Ais normally maintained-against the shank of the screw 60 by tliespring 46 and thuslimits the upward movementof the two-part member, 39, 43, Y

maintaining said member and the rparts carried and controlled by it sition. Y

When itis desired` temporarily to release or throw off `the defiector 27 'and concurrently to throw on the supplenientarypde- I the. key impulse, the finger 44,v willf swing jwith it and towards the end ofthe key -flector composed of the fingers 36,A the key 57 may be depressed, thus swinging-the member 39,43 downward and causing.they

pinion 37 to be turned by the intei'ineshing secto-r 39.to rock the shaft 34 and ,swing the guide lfingers first forward and'k down! ward and then rearward into coop' rative relationship with thei platen asin` Fig. j

As thev plateV 43 swings downward under stroke will engager-with the` contactface 45, pressing down on and releasing the paper deiiector 27, or'swinging it away7 from the platen to the Fig. 3 position. Fre-ni Fig.

v3, it will be observed'that the parts are ,so related that a work slieetmay `be introduced over the guiding surface. provided by the flatrinclined faces of the fingers 36 and thence will V,readily pass Vdownward through the throat 33. It will be understood that the described movement of the the Fig. 2 position to that of Fig. o

.defiector or guiding devices 27 and 36 from is independent-of the feed roller 10, and that said feed` roller may be in either operative or.releasedlpositionatthe time. On re'-v leasing the key 57, the parts will berestored in the Fig. 2 po v and 39 as before described. A side edge p guidefcontrivance designated kas awliole by `the numeral 64 will be mounted on the shaft v65 is an angular sheetV metal side guide 69 'to' normall positionVY by the `spring 46.

Shouldk it vbe. desired to 'lock the parts in Fig. 3 position so that both hands of the operator may be free to adjust or manipulate the work sheets or for any other purpose, the rearward key 56 may be depressed. This will result inV swinging the plates 39 and 43V downward, as beforeA and" will also tend to turn the locking plate ormeinber 5 1 with its 54 forward on its axis 55, with vthe result that as soon as thel locking notch at the tropof the slot 58 is brought opposite thescrew 60,'tlie shoulder 59 willv .swingunder the screw and' engage with it as in Fig'. 3, providing an interlock between the Vlocking plate 5l and the detent or screnT 6() to Imaintain the parts in depressed position. From this positionv the parts may be released by pressing the key 57 to-di`s engage the. locking plate from its detent and permit the restoringlspring 46 to return the ,parts to normal position..

63. Said lcontrivancev comprises aliub 65 formed with a hole 66 to Iit over the' shaft l63 and having)alongitudinal slotY 'tol fit over the blade6l. A thumb screw 68, Vcarried vby the hub, maintains the contrivancc in adjusted positions ylengtliv-rise of the shaft 63. Mounted on and carried by the huh having an upturiied side portion ,70 against It will be observed that by my present. in-

with the platen and paper feeding means, a spring pressed paper deflector, such as. 27.J andk key operated meansfor at will throwing saiddefiector away from theplat-en, the construction enabling this to be v'accomplished at any point in the carriage travel -without the said paper feeding means being` affected. In other words, the paper feeding` means or feed rollers may remain against the platen and yet the keys'of the defiector may be actuated to throw the deiector ofil or separate its front edge portion `from vthe' platen; Otherwise stated,"the key operated 'means foi-"releasing thedeflector Vis entirely 'which .theleft-liandfside edge lofthe paper" inayfbe guidedwhen tlliework sheet isfront fed downward over the supplemental pape:

` vdeflector into rthe'throat '33'. l I

'vention 'there is provided'iny combination f iso` independent of the release of the feed rollers. It is further to be noted that means are provided which are operative by one ley to throw one deflector off and concurrently for bringing the normally inoperative deflector into paper guiding position relatively to the platen, the thrown-off deflector, when thus released, providing a throat or guiding mouth which facilitates the introduction of the paper at the front side of the platen. lt is to be understood, of course, that paper may be introduced at the rcar of the platen 'over the detlector 27 and fed forward under the platen in the usual way, the` defiector 2T guiding the paper when thus fed and holding it close to the platen at the printing line. Also, the paper bail contrivance embodying the rolls 22.-93 may be employed in association with my novel devices to facilitate the guiding and controlling of the work sheets. rl`hus, for example, in Fig. 3 where the parts are positioned to receive the front-fed sheet a, the pressure bail is shown as maintaining the upper or advanced portion of another work sheet against the platen and so that it cannot fall forward and interfere with the proper front feeding or introduction of sheet a. After the sheet a has been introduced and positioned, the deflector 27 may be thrown on to hold it ane guide it as it is fed forward thereafter in the usual way. The bail or pressure device and the guiding device or supplemental deiector have a conrmon support, the latter device being mounted on the bail and thus being supported from the bail support, which in turn is the traveling carriage or carrier comprisingr in the present instance the truck l-a and the platen frame G, 7. Both deflectors while they may be moved relatively to the platen transversely thereof, yet have a consta-nt relationship with the platen, considered lengthwise thereof, during its traveling movements and whatever its longitudinal position.

In the present case, I am making only claims which are specific to the construct-ions shown herein as distinguished from my copending application filed herewith, Sr. No. 625,499. Broader claims to cover the constructions of both applications have been made in said (3o-pending application.
