Said truck supports a platen frame or carriercomprising two end bars l0 and a connecting cross bar or bridge piece comprising a vertical portion 16 and a horizonto the arms 28 that support the usual column stop bar 29 carrying Acolumn stops 30 with which evo-operate denominational stops 32. Slidably mounted on the paper table is an end stop device 36 provided with an end stop proper 36.

Curvinground the under side of the platen is a paper apron or deflector 40 that terminates below the printing line at the front of the platen, said delector being screwed to ears 42 that bear loosely on a sleeve or-hollow rock shaft 43 extending lengthwise of the platen and bearing rotatably in the uprights 19. The ends of the sleeve 43 are cut away, as indicated at 44, to co-operate with shoulders 45 on collars 46 screwed to a rock shaft 48 arranged within the sleeve or hollow shaft 43 and having projecting ends which bear in the end bars of the platen frame. Pairs of angular arms 49 bear loosely on the sleeve 43, each pair carrying a rod 51 that Sup orts the sections 52- of`a main feed roller. rawsprings 53 anchored. to the bridge piece' are connected to the arms 49 and -maintain the mainfeed roller sections norm-ally engaged with ,the

More specifically stated the object of truck as shown in my aforesaid patent. the invention is toiimprove the construction Lugs'or uprights 19, integral with and prodisclosed in my prior Patent No. 1,100,442, jecting upward from the part 17 provide 70 granted June 16, 1914, by supplying addisupports for the pressure rollers hereinafter tional controlling devices for one of the described. A rotary platen 2() having an work sheets. Y axle 21 is mounted on the carriage frame To the above and other ends, which will and the types '(not shown) are adapted to hereinafter' appear, my invention consists co-operate with the front face ofsaid platen. 7 5 `in the features lof construction, combinations A paper table 23 arranged behind the platen of devices, and arrangements of parts herehas ears 24 bearing on a rod 25 secured to inafter described and particularly pointed an extension 1()a on the end plate 10 and the out in the claims. corresponding extension (not shown) on the In the accompanying drawings, right-hand end plate.

comprising arms 56 and a cross bar 57, said carriers supporting marginal or terminal feed or pressure rollers 58. The inner arm of each carrier bears on the sleeve 43 and the outer arm on the rod 48. Drawsprings 59, anchored to the bridge piece, constantly press said' terminal rollers towards the platen with which they are adapted to engage through openings 58a in the deflector 40. Crank arms 61 fixed to the sleevev or hollow rock shaft 43 are provided with studs 63 which overlie the associate arms 49. When the shaft 43 is rocked it will operate through the crank arm 61 and lstud 63 to swing the arms 49 downward and overcome the springs 53, releasing themain feed roller throughout its length, thisf movement being independent of the terminal rollers 58 and 4being accomplished by devices comprising a plate-like arm 65 which is secured to the ,sleeve 43 and isadapted to co-operate with.'

v a wheel or rotary cam 69 having a pivot 70 adjustably mounted Fin the bottom of the depression 3. During the traveling movements of the platen carriage the arm 65 will engage with the cam 69, the cam operating to force the arm rearward, rocking the sleeve 43 and automatically releasing the main feed roller during the carriage travel. At the same time the loosely mounted deflector, which is normally maintained in spring pressed engagement with the platen as herelnafter described, will be freed and will drop down at'its forward portion away from the platen, providing an opening or passageway for the paper introduced at the front. The terminal rollers 58 are releaslable at will by devices comprising crank arms 76 fiXed to the shaft 48 and having studs 78 overlying the outer arms 56 and adapted toswing said arms on the shaft 48 to overcome the springs 59 and release the rollers 58. The shaft 48 may be rockedas described by devices comprising a crank arm 79 secured to one end of the shaft and connected to a link or strap 81. enlarged at lits upper end and receiving a boss 82 integral with an arm 83 pivoted eccentrically of the boss 82, said crank arm terminating in a finger piece vor key 85. By-pushing the key 85 rearward the strap 81 is pressed downward, depressing the crank arm 79 and rocking the shaft 48 to release the'terminal rollers 58. This movement'of the shaft 48 'op-I erates through the shouldered collars 46 to rock the shaft 43 and effect the release of the main feed roller simultaneously with the marginal rol lers. The shaft 48 as it turns forward brings the shoulder 45 at the forward side of each collar into engagement with the corresponding cut-ofi' or-shoulder 44 on the shaft 43, thus forcing said shaft to turn with the shaft 48. rFhus the main or intermediate feed or pressure roller is releasedeither automatically or by hand,

the automatic release occurring independ-w ently of the terminal rollers while the manual release on the other hand is effected concurrently with that of the terminal rollers.

1 A spring bail is provided to co-operate with the front upper side of the platen, said bail comprising side arms 86 and a cross rod 87 having pressure rolls 88. The arms 86-are secured to a rock shaft 89 which bears in brackets 90 fixed, to the carriage truck. Drawsprings 91 exert pressure on the bail to maintain the rollers 88 contacting with theplaten above the printing line.- On the cross rod 87 is mounted a side guide or gage 92 which co-o )erates with the left-hand edge of a narrow s eet 94, the width of said sheet being less than the distance between the terminal rolls 58, the gage 92 being adjusted somewhat to the right of the left-hand roller 58. The rollers 58 co-operate with the side margins of a wide record sheet 95 whichis introduced into the machine from the rear in the usual way, the side gage 39 cto-operating with the left-hand edge of said record sheet to position it properly lengthwise of the platen. The record sheet is passed up at the front side of the platen together with the7 transfer or carbon sheet 96 and is controlled by the rolls88 above the printing line; In order further to guide the narrow sheet 94 when introduced at the front, there Y sheets usually Icomprise a plurality of folds with interleaved carbon sheets, thus making a comparatively,` thick packet, although for convenience of illustration a single thickness only is shownfA in the drawing. This thickpacket is difficult to control properly, and in order to maintain it. close to the platen, especially in the neighborhood of the printing line, I have found it desirable to provide additional controlling devices withy which my present invention is morel particularly concerned. Said ladditional devices comprise pressure rollswhich vare arrangedv along the platen at the front side thereof just below the printing line and are coupled up or so connected with the main roller 52 as to be automatically controlled by the devices which control said roller 52. My novel devices comprise ears 101 which are fixed to and project forward and upward .from the understood from Fig. 6. From an inspec-- release rock shaft bears in an ear 178 projecting from the left-hand end portion 'of the bridge-piece. lln the present instance the rock shaft 102 `terminates short. of the righthand end of the bridge-piece but this is a matter of detail and where desirable the rock shaft may extend the full length of the platen and the bridge-piece. Mounted on the rock shaft are a pair of roller carriers, 'each pair comprising two crank arms 103, provided with inwardly projecting hub portions 104, which iit over the rock shaft 102 and bear loosely thereon.` Each pair of carrier arms 103 are confined between two of the ears 101 which prevent outward displacement of said armsin, respect to each other. At their outer ends the carrier arms are perforated to provide bearings for pintles 105 and pressure rollers 106. These-*pressure rollers may be of metal and are forward or out of line with the main and terminal rollers which are in line with each other. Said rollers 106 are adapted'to co-operate with the platen 20 at its front lower side below the printing line, protruding through narrow slots or openings 107 in the front portion of the deflector 40. The side edges of the deflector outside the openings 107 rest on the free ends of the carrier arms 103, the swinging deflector 40 being thus supported by the carriers. The pressure rollers 106 are constantly urged towards the platen by springs 108 that are coiled around the rock shaft 102. There is one of these springs arranged close to and inside of each of the hubs 104, one end of the spring bearing in a hole in the collar and the other end abutting againstthe front face of the part 16 of the bridge-piece. Collars 109 secured by set screws l110y to -the rock shaft 102 prevent displacement of the springs in respect to the hubs 104 and also prevent unduemovement-of the c arrier arms 103 of each pair towards each other. This feature of construction will be clearly tion ofv -F ig. 2 it Will be noted that the supplemental pressure rollers 106 are arranged forwardof and so to speak inside the marginal rolls 58 so lthat said rollers 106 are adapted to co-operate with the marginal or'side portions of the narrow sheet 94 and not with the edge or marginal portions of arranged outside of the wider sheets 95 Aand`96. i

It is desirabler to release the pressuredevices 106 automatically at the same time'that the other pressure' devices 52 for the narrow sheet are released, and to this end means are provided which comprise crank arms 111 provided with hubs 112 which lit over and are secured by set screws- 113 to the rock shaft 102. Une of these crank arms 111 is each ear l101 and in association with the carrier or crank arm 1 03 inside vsaid ear. A lateral pin .114, xed

arms 49 to effect this. result 16 of the bridge-piece, provides room for theY crank arm 115 and also for the forward portion of a horizontally arranged link 119 which is pivotally connected at 120 with the crank arm 115. The rear end portion ofthe link 119 is somewhat higherthan the front portion, to which it is joined by a curved or odset part, and is pivotally connected at 121`with the free outer end of an upstanding crank arm 122 provided with a hub 123 which fits over a stub rock shaft l124 and is secured thereto by a set screw 125. rear of the bridge-piece and its left-hand end lbears rotatably in an ear 17| projecting -rearward from the left-hand end of sairl bridgeiece. The right-hand end portion of the s ub shaft 124 bears in the left-hand upright 19. A collar 126 fixed to the stub shaft at the left -of said lugvprevents endwise displacement of.' said stub shaft to- Wards the right, while the collar` 123 contacts with thel inner face of the ear 171 to Vprevent displacement of said stub shaft towards the left, the stub 'shaft being free, however, to rock or rotate in its bearings. Rocking motion is communicated to the stub shaft from` the hollow rock shaft or sleeve 43 by means of a crank arm 127 on the righthand end portion of the stub shaft which projects beyond the lug 19. Said crank arm extendsupward and'its. free end is formed with aslot 128 which is loosely engaged by a pin 129 that'projects laterally lrightward from the left-hand arm 49. y

lt will be understood that the Supplemental pressure rollers 106 will be released when the key 85' is actuated to release'the rollers 52 and 58,\and that. said rollers 106 will 4also be released when devices 65 and 69 a operate during traveling movements of- The stub shaft is arranged at the i 1 the former instance this will result in the l 'rocking of the shaft 48 acting through' the shouldered collar 46 to rock the shaft 43y and Vtorelease the main rollers 58, vas has been described, the pins 63, depressingthe Simultane ously the pin 129 on the left-hand arm 49 will act on the crank 'arm 127 to rock the shaft 124, Swinging the crank arm -122 rear-v y ward, Vthus drawing rearward thelink 119,-

swinging the crank arm 115 rearward and rocking the shaft 102. The movement of said shaft 102 in turn will be transmitted through the crank arms 111 and pins 114 to the carrier-arms 103, which will be swung forward, overcoming the springs. 108 and throwing the rollers 106 to the released position in respect to the platen. 1t will be understood that the springs 53 will, through the described train of connections, affect the pressurerollers .106 to some extent during this restoring operation.

On the other hand, when the plate-like arm 65 is acted on by the cam 69, the sleeve 43 will turn independently of the shaft" 48, releasing the pressure rollers 523vithout affecting the terminal rollers 58. During this releasing operation the actuating pin 129 will operate as before through the train of connections comprising the crank arm 127rock shaft 124, cra-nk arm 122, link 119, crank arm 115, rock shaft 102 and crank arms 111, to swing the carrier arms 108 and throw off the rollers 106 simultaneously with the rollers' 52. The parts i when in the released position just described are illustrated in Fig. 3. The restoration of the parts to 4normal position will be effected automatically when -the arm 65 is released from the control pf the cam 69 by a suitable movement of the carriage.

The mechanism herein described is adapted for use with various forms` or styles of commercial typewriting, although in. its` present form it was more particularly designed for the writing of tax bills and records thereof. In using it for such work vthe operator first presses the release key 85 rearward, releasing all the feed rollers. 'The record sheet 95 and carbon sheet 96 are then introduced together at the rear of the machine over the paper table, vproperly positioned against the side guide 39, and are passed downwardly around and under the platen and over the deflector 40, being advaneed above the printing line and' int-roduced under the pressure bail. The release key 85 is then returned to normal position, resulting in the return of all the pressure rollers into co-operative engagement with the platen. The carriage is then released from the escapernent devices, as by a release key or through a tabulating operation, and permitted to move towards the left, bringing the arm into engagement with the cam 69, releasing the main feed-roller-52, the supplemental pressure rollers 106 and the deflector 40, but independently ofthe terthe narrow sheet or sheets 94 from the front of the machine, guiding said sheet or sheets agalnst the gage 92. Said sheets are front the rolls 88, and thence downward between the platen and the supplemental rollers 106, being slid rearward over the deflector 40 and passing between the mainl feed roller 52 and the platen, the side edges of said sheet or sheets of course clearing the terminal rollers. The end of the sheet or sheets will 'be arrested against the end stop 36e. The operator then restores the carriage fro'm left to right, the main and supplemental feed rollers and the 'deflector engaging with the sheet or sheets 94, which will thus be controlled in superposedrelationship with the record sheet and in position to receive the line of writing. Assuming -that as usual each narrow sheet or taxbill 94 receives but a single line, the carriage will be released whenthe end ofthis line has been writtenycausing the arm 65 to co-'ope'rate with the cam 69, thus releasing the written sheet or sheets 94, which may then be removed and substituted by another sheet which willl undergo the manipulations hereinbefore described. In restoring the carriage from left to right the usual line spacing'handle will be operated, first to space the record sheet prior to the restoration of the` main feed roller into engagement with the platen so that the line spacing operationfdoes not affect the newly ladjusted narrow sheet but only the underlying wide record sheet. This underlying sheet ofcourse receives the typJev impressions through the carbon .paper 96, slmultaneously with the writing of thenarrow sheet. Y

As has been'stated, the tax bills usually comprise a plurality of folds withv inter-l leaved carbons, making a thick packet and` my present improvement has been found in practice greatly to facilitate the control ofthe printing portion of such a packet maintaining the portion of this packet opposite the printing line in proper condition mechanism disclosed in my aforesaid 'prior 'Patent No. 1,100,442. f

Various' lchanges may be made without departing from my invention. For example,

it may bef found necessary positively toucom nect thelpressure rolls 106 with .the vplaten 20 lto insure proper feeding of the paper. 1.30

fed over the guide rod 97 and forward of ies shaft at its left-hand end a small toothed wheel or pinion 131 which constantly intermeshes with a toothed wheel 132 which is fixed to the left-hand end of the platen axle 21. The shaft 130v may be supported near its outer ends by additional hanger arms 138. By this construction the pressurerolls will always be caused to turn by rotary movements communicated to the platen.
