Collars 25 are fin ed'tothe rod by set screws 26 and coopera'te-with the ends of said hubs to pre ven'tfendwvise displacement of the armsfQO' along their'supporting rod. Sa'id rod isse cured in place on the end bars by cross pins 27 provides a tie rod or strengthening member fonthe carriage frame as Well as constituting a bearing for the arms20i" The pivots19 carried by said arms are preferably shouldered screws which are threaded into enlarged portibns or bosses 20? at the ends of the armsQO these bosses servingtol'spa'ce the arms or carriers 18- away from the'arms' 20 so as tb aV'oid frictibn or rubbing when thecarriers or' cradles "turn'on their-pivots 19.

To support certain of the parts I provide a pair of angular bracket members arranged one near each end of the carriage and each comprising a vertical forwardly extending branch or arm 28, a horizontal forwardly extending branch or arm 29, an upright vertical portion or short neck and at the top thereof an angularly disposed bar-like portion 31. Each bracket member 2831 is secured to a web portion 3 of the rear bar by headed screws 32. The tie-rod 22 passes through bearing openings formed in the bracket arms 28 near their forward ends, an additional support for said tie rod being thus provided. Secured by screws to the outer webs 3 are flat springs 34, the for. ard free ends of said springs being so shaped as to engage effectively with the under portions of the enlargements 20 of the arms 20. The springs 34 press upward constantly against the arms, and their tension is thereby transmitted to the carriers 18 and the main and supplementary feed roller devices, the spring means or devices 34L tending constantly to maintain the feed roller elements 10 and 13 in spring pressed engagement with the under side of the platen 5. The sections 10 and 13 of the feed rollers protrude through cut-outs or openings 35 and 36 formed respectively in the rear and forward portions of a paper deflector or apron 37, said deflector being pivotally supported from the pivoted arms 20. To this end the deflector supporting arms 38 are pivoted at their rearends on shouldered pivot screws 39, which are threaded into the outer faces of the bosses or enlargements 20" of the two outside arms 20. The arms 38 extend forward and at their forward ends are provided with outwardly extending lateral bearing pins 40 which are engaged by perforations in ears 4-1 extending downward from the deflector 37, the deflector being thus pi v otally supported at the forward ends of the arms 38. Portions-of the deflector projecting rearward between the feed roller sections 10 may rest on the small supporting rolls 10. The deflector is constantly pressed upwardly at its forward side by spring means comprising con'iparatively weak wire springs 42 that are carried by headed pins 43 extending laterally outward from the arms 20. One free end portion of each spring bears against the associate hub 21 and the other end portion re-acts against a pin 44 carried by the support or arm 38. The arms of the springs 45 tend constantly to spread or separate and the re-action resulting presses upward constantly the f0rward portion of the paper deflector 37. The upward movement of the deflector is however limited by the pins 44 which are extended laterally inward from the arms 38 far enough to underlie the associate carriers or cradles 18, acting as stops thereagainst,

the construction being such that the upward movement of the deflector is limited by the feed roll carriers. The paper introduced at the rear is guided into the bight between the platen and the paper deflector 37 over a two-part paper table, the forward part only of said table being shown herein and numbered 45. The paper table part l5 is secured to the bar-like portions on supports 31 of the bracket members and said paper table part is formed at its forward end with fingers 4G to it into corresponding notches or openings in the rear end of the paper deflector 37, thus blocking the opening between the two parts so that paper may not slip through.

Passing between the platen 5 and the deflector 37 at the under side of the platen the paper is advanced at the front side into the control of paper finger contrivances or guides 47. Each of these is preferably made of a singl piece of sheet metal and comprises an upri ht portion 48 and an integral horizontal disposed portion 49. The portion at its upper end above the printing line carries a pressure roll 50 which is mounted on a pivot 51 carried by the paper finger. The horizontal portion 429 is provided at its lower side with a contact device which is effective to actuate line locking mechanism not shown herein. N ear its ends he horizontal portion 49 is provided with pairs of clips or engaging devices 53 struck from the sheet metal of the portion a9 and which it over a rod or rectangular supporting bar 5a which also carriers an inset platen scale 55. Said barv 5% extends along the platen at its front side and below the printing line, and the contrivances or fingers 47 are slidably mounted on said bar. Screw stops secured to the end portions of the bar 5% limit the outward movement of the paper fingers 47, of which there are preferably two. In order to facilitate the removal of the paper fingers from the bar, the latter near its outer ends is cut away at the under side, as indicated at 57 enabling the paper finger when slid down to the notch or cutaway 57 to be unhooked or pulled forward, so as to be readily removed without displacing the bar itself, as graphically shown in Fig. 4, which illustrates the left-hand paper finger in process of removal. Preferably the inner clip at the lower side of each part -19 is straight and not hook shaped as are the other clips 53. The straight clip 53 facilitates ready removal of the paper finger, permitting the cut-away to be shortened, since it only necessary that the lower hooked clip 53 be opposite to it to enable the paper finger to be slipped off the bar. The paper finger bar 54k and the paperfingers are pivotally mounted, and to this end the bar 54 is provided near its outer ends with rearwardly extending lugs or tongues 58, said lugs being perforated laterally, as indicated'at 59, to fit over and engage with hearing pins carried by the forward end portions of the bracket arms 29 and extending laterally inward therefrom. The bar 5 lfisadapted to receive rotary movements on the pivotal centers or pins-60 so as to swing the paper fingerstowards and away from the platen. The freeends of fiat springs 61' overlie the rear =end's of the tongues 58; said springs being secured by screws 62 to the tops of the bracket arms 29 and extending forward'towards the tongues against which they-press constantly downward; tendingthereby, to maintainthe paper fingers in co operative engagement. with the platen. The paper fingers are adaptedto'be-released simultaneously or concurrently with the feed rollers, as hereinafter explained',=but may also be re leased separately and independently, and to this end the right-hand end of thebar 54 is provided with a paper+fingerrelease-key in the formof an arm 635- said armnbeing provided at its rear with a lateral extension 64 disposed behind the bar Set andisecured thereto by headed screws The arm=63 extends forward over the top of'the-bar and terminates in ayfinger'pieceuor.key proper 66. By; depressing this key '66 the :springs 61- may be overcome and. the-paper fingers 47 swung forward away from the. front face of the platen without;disturbing theifeed rollers. i

By said invention'there' is nrovi'ded aiplaten and a feed roller in combination with a pressure; device constantly tending to -maintain said feed roller in c0- operative engagement with the platen, and releasing means I operative "directly .onf said pressure device. The pressure device in the present" instance comprises a plurality of flat springs, and the releasingmeanscomprise" a corresponding. plurality of key controlled-1 pins co-facting directly with the springs -to fleX them and thus relieve the feed-roller 'ofi'pre'ssure. This construction pose" the 'weig t I of the feed "roller mecha- 1.; effective on both the main and secondary fkzdi, roiler mechanisms. Also, the paper 1, and the paper deflector are similarly controlled and released by flexing their pressure springs so as to relieve the paper fingers and paper deflector of the spring pressure towhich they are normally sub jected. The springs for the feed rollers and for the paper fingers are oppositely acting, the former pressing upward and the latter exerting a downward pressure, and, consequently, oppositely acting releasing devices in the form of duplicate crank arms are provided to act oppositely on the springs.

Various changes may be made without departing from my invention.
