' lie it. known that. l. llnwaiin B. llizss. a i

ioitizen of the United States of America, re l siding in the inn-ongliuo'f lh'ooklivii-t) and State of New' York, have invented certain 1 'linprovenieiits iii \\'ritingMachines, of i E\\'lii-'h the following is a speeitieation.

'l`his invention relates to paper i'eed de- `vii-es adapted inore partienlarlv to sight 'inaehines ot' iiie elass in which the tvpe hars iinpinge iipon the front. face of the platen.

in inan'v lsneh devices, heretofore devised, the ordinar'v front and r'ai teed rolls loeaied helow the axes oi the platen, iisiially wiih tho ordinary pan or paper gnide hetweeii thein. have heen spring pressed toward the piateii and provided with ineans for inoving tiieiii against the tension of ilie spring snpporting or sustaining nieans away :fi-oni tho ihiten to facilitate adjnstineiit oi`l paper in t ie inaehine or for the insertion ot' a plurality of sheets. ln the operation of throwing oill the feed devices oi' inoving tliein against the, tension of their siipporting spring or springs eonsideralile strain is iniposed npon the parts and itI has heen necessary to nnike them relatively heavy adding thereinto the weight' of the traveling ear I ringe and to the 'cost of inaniifaetnre.I

'l`his invention eoniprises a novel organization wherein the teed roll sustaining l ineans. otl whatever character` may he ref leased so that the rolls tendl to fall awav fi'oin the platen h v the action of gravitini t)rdinnril iind indeed, prefeiahlv tho feed rolls will he spring supported. and as eonteniplated h v this invention the snstaining spring or springs will nothave tension iniposed npon tliein in the operation ot throwi ing oil' the feed devices.

'lhe prinnirv i'eatnie of this invention eonsists in nioving the ordinary fixed point. 1 oi siipport or ahntinent. of the feed roll i sustaining ineans or spring so that. the feed if devices niay inove away froni the platen in' the action of gravity. 'l`liis teatin'e of novelty inav lie einhodied in inanv st vles ot spring siistnined pa ier feed devices. l irot'er to snstain the iiecd devices hv pent anty f eoiled springs whose npper ends are ati iaehed to niovahle snpports that are lowered i whenl the feed devices are. thrown oil'. Sach snstainiiig springs may, however, he ari ranged in a varietv oi wavs as for inst-ance horizontally. 'lhis invention, therefore, hroadlv eonsidered, con'iprehends anv np-i p ropriate way in which the deserihed opei'ation ninv he. neeoniplisliml and is not dei t'eed devices nor iipon the partieniai' kinds 5 I4rel ieve iis lei-isiii'ii.

l pi'et'er that their adjnstinent shall he sin-h tion for the reception of ii sheet to he printed o t spi'iiigsl nor particular iii'rangcinenti tlieieol. rHilf"iiife'iilioilmis broad eiiOitgl-i to ineinde arrangements in which .the spring or springs are not coiled springs snlijeeted to extension or compression. The. spring may be 0f other forins and its snpport or ahnt'inent he in oved to 'n "l'iicr'iniieetion with snch novel arrangement. of siistaining springs, l

thaty when the machine is in normal condinpon. the spring shall act inerelv as do noneonipressihle'or non-extensiiile devices` sin-:h for instance as a inei'e link. to snstain the Feed devices in proper relation to the piateii. if the feed devices are siispended h v pendl :int coiled springs these. springs niav he oi`-t siich strength thntthey can aet nierely as links for the. noriiiai snpport of the paper .l i'eed devices heing then nnder no spi-inf.:l tension or extension. Under sin-h conditions a single sheetI or two sheets oi paper oi" ordinary thickness with interposed earhon niay readily he carried throngh the niai chine. h v rotation of the platen withontl iniitt posing any expansion o* appreciable tension iipon the supporting springs, there heing;l siiilicieiit elasticity ot the, snrt'aees of the i'olls and ilaten. That. snrh ina v .he the operation. have deinonst rated hv siispending the feed devices h v solid links. When the springs` are ot the. character stated and arranged as deserihed. tlie insertion ot an asseinhlage of sheets of increased thicknessl in iposes iipon the siipporting spring a tension eori'esponding;r in a way with the. thickness of the material inserted hetween th'e platen and the feed rolls. lixperienre has shown that with this arrangement the. tension increases in proper relation to the inserted assemblage of sheets which will his` properly .carried aronnd the platen hv rotation thereof. Paper feed devices constructed in aecordance with the aliove suggestions have heen shown by experience to lie highly eilicient Ii in action and to possess the advantages snggested in the way of lightness of weight and eeonoiny of construction. 'l`he weight of the .feed devices, even when the)y are inado as light as feasible. is snliieient to eanse tliein to fall away froni the platen, no spring to draw theni away heing reqiiired. ln the present instance, l have shown the v'I invention applied to an organization ot paper feed devices resenililing in sonie respects that disclosed in niy latent No. 561.075.' 'lhere` is a loosely nioiinted or tloating i'raine carrying the frontand rear t'eed rolls and paper gnides, that is to say, the traine is '.apalile ot" nioving np and down with l reference to the platen and oi' ennt'oriniirr; I thereto in cont-radistiiietioii to heing inonnted to swing alienta. iixed axis.

A pendant link 12 is pivot- :illy connected with the frame plate, 8 located at the right hand end ot the pliiteii :the point of eoiineet-ioii being shown as loirated in front ot the axis of the rear feed roll shal't. .\t its upper end the link 12 l' is pivotally connected to a horizontally disl posed lever 13 pivoteil intermediate its ends at 14 upon a pin projecting from the side plate 'l`o the rear ot this pivot, the lever lt. is formed with an elongated slot through lwhich projects a pin li'i on n lever iiiiii 'lt'. pivoted at its lower end disposed in an iipright position and provided at top with the usual linger pieee. 'lo n projection IT on the lever 1:1 in front of its pivotl 1lis secured a llat or plate iuetal spring 1S formed with two rece. es 1t) and 20. v ln normal working posit-ion the pin l5 lies `in reet-ss .'ti and eonstitutes 'an abutment tor that end ot the spring. 'l`lie reaetion of the spring is sneh as to tend to lift the l'ioiit end ot' the lever 12 and eiiiise link 12 tto siistiiiii the leed devices with the rolls llin contactl or iii very elose juxtaposition to the surlaee ot the platen. When the levei' iai-iii 1t; is dra'wn forward, pin lii passes to ilhe recess 19 iii the plate nietul spring and pei'iiiits the t'eed devices to drop awayifron'i the platen. 'l'lie gears 3, sl, are so pi'oporltioiied that the ieiii' pressure or feed i'oll lis driven at the. saine sui'l'aee speed as the l f [platen and the geni-ii are of such depth that ltliey do not pass out of engagement when sections 't'.

'l`he intro-4 ot substantial thiekiiess (in making a nuiii lier ot manifold copies) will cause. llexui'e y of the spring owing to the laet that' the l rollers are now forced away from the sni face of the platen by the thit'ltiiess of thi papers introduced.

With a t-.onstriietion of this gen iinide very light because there is no .strong spring tension normally imposed upon theii tween the platen and the rolls. l have found, therefore, that. it. is sullieient to have a supporting link 12 at one end ot the i l l l platen only, although it desired a siinilai t link may be placed at the lel'tV hand end of the platen in which ease the pivots ll Ilii Fig. 3. the saine general emistruetioii ol leed devices. liaiiie pieces n'. l'roiit and lshown and as bel'ore ilie l'eed deviees are `guided veitieally by pins lll working in :arm Q2 is formed with ii usual linger pieee and carries a laieriil pin i slot Q-t in a horizontally disposed lever arm l 25 pivoted iit its i'eai' einl and at its l`i'ont i end equipped with an adjustable vertieallv is tliiupper end olii coiled spiiiig 'i' whose eral character, the feeding devices may la .substantial thickness ot' sheets passes lie-` parts are in normal position.

When the release lever is drawn forward, the cani face moves downward and roll G1 passes to the Si low face (ifi thereof as indicated in Fig. S and the spring being released, the feed devices move. or fall away b v gravity to the release position shown in the latter figure.. .\t. thosanie time, the rocking of the shaft i Ill throws oll' the margin rolls. A projection (3G, on the lower edge of the side. frame plate S engages one end of a lever arm 6i' mounted iiiteiiiiediate its ends on a roel:

an upright ai'iii 68 that carries the scale barik G0. A spring having one end attached to the arm (3S and the other to the rock shaft i 11. tends h v its reaction to draw the scale bar against'. the face of the platen. When l tho operation described occurs, tho weight of the paper feed fianie with its rolls exerted against the rear end of lever G7 will i overcome the tension of the coiled spring T0 and will raise the scale bar to the printf ing line. At the other end of the platen i there is a similar lever mounted on roelt' shaft GT', a similar projection (itl on the edge of the frame plate, a similar s iring 70 and arm (3S to which latter the end of the scale bar is attached. At the right hand side of the machine, a lever arm 71 is extended upi wardly from the axis of the lever GT and, by its inaiiipiiliitioii, the scale bar may be moved from the line of print independent-ly of the. movement. of the release lever tl. A u eoiled spring 72 applied to the'release lever and. when the release lever is drawn forward and the paper feed devices dropped, the spring passing the axis of the release l lever tends to then hold the feed devices in olf position.
