TYPE-WRITING mAcnINn Specification or Letters w I Application filed June/9, 1918. Serial No. 102,641.

Tooll whom it may concern: I I

Be it known that I, (31.10 B. YAW, 01th zen of the United States, and resident of Arlington, inthe county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Tvpe- Writing Machines, of which the following writing machines. One object of the invenpaper; second, a paper guiding device on .is a specification. 1

The present invention relates to paper controlling and guiding meansfor typetlon is to provide improved ,pa'per controlling and guiding means which include, first, feed roll devices which cooperate'with the platen and from which the platen may be swung 'away to facilitate the Introduction of the carriage whichis associated with a stationary paper guidin device whereby long sheets may be emp oyed substantially 1n a flat condition; third end stops for the paper, one'of the end stops being movable with "the carriageand the other end stop be-' ing stationary, the movable end stop being settable out of the wayso that a free passage for the paper'or worksheet to cooperate with the stationary end stop-is afforded. Other specific objects will hereinafter ap- To the above and other ends my mvention consiSts iI l thefeatures of construction, combinations of devices and'arrangements of parts 'hereina fterdescrilbed and particularly pointed outin the claims.

Devices are provided for preventing the I separation or disconnection of the track-' way 4 and the slide bar 12, these devices being inxduplicate at the upper and lower sides of the track-way 4. Wlth each set of balls "11 --is associated a separator in -the formof a plate 13' (Figs. 3 an-d 5), the plate being perforated to provide openings forfthe'ballswhich are thus maintained properly spaced apart as is usual. Each separator 13 is twisted and shaped near its ends to provide lugs or projections 14, which lugs act as stops, cooperating-With. stops or projections 15 fixed in theb'ottomuof the track portions of the slide bar'12. Relative endwise; movements between the slide bar 12 and the track-way 4 are 'limitedjn both directions by-the stop devices 14 and 15, so that disconnection of the carriage from its bearing is prevented even when the parts have been detached and removed from the 'Other end bars 17 fixed to the slidebar'12 '50 v v shaft 30 which takes, bearings atjits ends} in outside the end bars 16 project downward.

The carriage further includes a platen car rier or frame which is pivotally supported onjthe truck-portion of the carriage hitherto. described and including the slide barv 12 and two pairs of end bars 16 and 17. As described more in detail in my pending application Sr. No. 875,103, filed December 2, J

" 1914, said platen frame comprisesacap or housing 18 at the right-hand end ofthe frame and parallel cross bars 19 and 20,

} which are detachably fixed to said cap and extend leftward therefrom, being secured I at their left-hand ends to the left hand end 15 bar 21 of the platen frame. J ou'rnaled on the platen frameare theaxle portions, 22

and 23 of the axle of a cylinder platen 24.

Coiiperative with the, front' face of said platen are vprinting instrumentalities, notshown, but which may be of any desired con} connected at .26 tothe left-hand end bar 16 of the carriage truck. The pivlotal connee- 'tion of theplaten frame with vthetruck is, it

will be observed, below the platen and substantiallybeneath the platen axis.

'In' order better to controlthe swinging movementsof the platen frame on the car riage truck, additional connections between .-the.platen :frame and said] truck are em-.

vices which coiiperate with its front face, 2

said paper feeding devices serving also as stops to limit the forward swing of the platen and hold it in normal position;

-The paper feeding devices comprise a feed roller composed of sections 32 arranged lengthwise of the platen above the printing line and a similar feed roller comprising sections 33 arranged'below the printing line. [The sectional feed rollers are supported on parallel shafts 34 which bear at their, ends in rockers 35, Each rocker is pivoted at 36 'midway between its -ends on the-adjacent end. barv16,which as shown in Fig.- 3 is 0 outward from each rocker 35 engage loosely curved or olf-set'inward.

The rear end of the guide iio' .plate which terminates behind the slide bar 12 is near its lower end bent at right-angles f from the body portion as indicated at 46.. :The sides '47 of the guide plate are bent upward at. right-angles from the face thus pro vidin'g a sort of trough for the paper which may be'rea dily-insertedor front fed asit .theeFiggzZ ,-.positi0n. 'Itwill 'be noted that the Fig. 2 position.

.- Mounted ongthe. carnage are paper end stop devices, which devices are especially useful when a short sheet or card is em- ,ployed. Said end stop devices, as illustrated 'in :Figs, 1, 4, 6 and 7, comprise a rock shaft or rod 48 whichhas fixed to it a stop blade 49,. the ends of said rock shaft bearing in arms 50.fixed to the inner faces of the sides I 47. Fixed to the left-hand end portion of said rock shaft is a short crank arm 51 which .is provided with an outwardly extending portion or off-set 51 that carries a finger button 52. The right hand end portion of the rock shaft is provided with a lug 53 which coeperates with the free end of a leaf spring 54 to hold the stop blade in either working or non-Working position. The working position of the stop blade is shown in Figs. 1 and 4, from which it is clear that the blade blocks the passage of the paper and provides an arresting face for the bottom edge thereof when it is introduced. By turning the finger button 52 the rock shaft may be rocked and the blade thrown to the inoperative position indicated by dotted lines in Fig. 4 from Which it will be understood that a clear passage is afforded for a farther downward advance of the paper. This, of course, is necessary when a longer sheet is employed.

When longer sheets are used additional paper guiding and paper stop devices are preferably provided of the character illustrated in Figs. 1 and 6. Said devices include what is in effect an extension of the movable or traveling. guide plate 42, the, extension, however, being stationary. The stationary guide plate designated as a whole by the reference numeral 55 comprises a surface or tangular frame 57, said frame at its sides being provided with brackets 58-comprising parallel arms 59., 60, the longer arm 60 having a hole near its end, and the shorter arm 59 terminating in a. semi-circular depression indicated at 61. The holes in the longer arms 60 fit over the reduced end portions of round extensions or rods 62 extending laterally outward from the rear portion of the base 1, said arms being slightly yielding so as to enable them to be sprung over said rods. Thedepressions 61 in the arms 59 similarly fit over the reduced end portions of companion rods or pins 63 which project laterally outward from the base 1. Latches 64'pivoted to the brackets 58 coeperate with the rods or pins- 63 to lock the table or guide device 55 in fixed relationship with the main frame. Saidtableit will be observed is inclined so that it is in the sa'me plane as the guide plate 42 and is virtually an extension 1 V thereof, the portion (46 of said guide plate being contiguous to the upper part of the frame 57; The stationary table or guide plate 55 inclines downward behind and belowthe typewriting machine and is' of such length and width as to accommodate comparatively long wide sheets of paper which thus may be introduced into the machine and fed out of it in a comparatively flat conditable portion 56 suitably secured to a'rection, this .being an advantage especially where the paper is thick or somewhat stifl".

Additional paper stop devices are provided that are mounted on the stationary guiding device 55, said stopping devices as shown in Figs. 1 and 6 comprising a blade or bar 65 extending crosswise of the table top .gularly bent portion 67 which projects up- Ward at righ -angles to the table top and is pivotally connected at 68 to the inner end of M an arm 69, the outer end of said arm curving downward and being provided with a hub 70 Which bears slidably and rotatably on a guide rod 71, that is arranged at the left -of the table top and extends parallel therewith, said guide rod beingsecured at its ends to lateral projections 72 from the frame 57. A. handle or finger piece 73 fixed to the arm 69 above its hub and extending laterally leftward affords a convenient means for throwing the. stop bar 65 upward out of operative position. Pivotal movements ofth'e stop bar on the arm 69 are limited by means of a screw 74: carried by said arm, which is engaged by a slot indicated at 75, which slot is formed int-he left-hand end of the angular portion 67.

The stop bar 65 is kept in cooperative engagement with the table 56 by a spring means comprising a draw-spring 76 connected at one end to the arm 69, the oppo- ,106 site end of said spring bein anchored to a plate 77 which is slotted at 78' to embrace loosely the sides of the arm 69 and is curved to seat itself against the hub 70 adjacent to said sides. The opposite end of said plate 77 coiiperates with a rod 79 which is arranged parallel to the rod 71 between said rod and the side of the frame 57, said rod 79 being supported at its ends on the projections 72. The construction is such that when the finger piece 73 is pressed down the arm 69 is swung up lifting the stop bar 65 from the plate 56 and enabling the whole stop contrivance to beslid up or down lengthwise of said plate to any desired position, 20 the range of the contrivance being substantially the length of the plate. The pivotal mounting of the stop bar 65 is such that the spring 76 maintains it in proper 00- operation with the plate 56, the individual springs of the stops proper 66 taking care again without substantial bending. With the platen thrown back as inFig. 2 the paper is inserted into the machine, its lower end passing through the wide throat or opening between the platen and the feed rollers 33 and 32, the paper passing downward over the supporting and guiding surfaces 42 and 56. The frontfeeding of the aper will continue until its bottom edge 1s arrested by the end stops 66, which, of course, have been previously'adjusted so that when the paper is thus arrested it will be in position for receiving the first line of print. On the restoration of the platen from the Fig. 2 \tothe Fig. 1 position the paper will be held in proper relationship with the platen by the feed rollers 32 and 33 due to the pressure exerted by the springs 39. The width of the table 56 is such that it.will support substantially the full width of the lower portion of the sheet even while the carriage is at the extreme limits of both its righthand and left-hand travel. During carriage movements, of course, the lower portion of the paper will slide over the surface of the table 56, which remains stationary, a relative movement between the two portions 42 and 56 of the paper support or guide taking place during such carriage movem ents.

Endwise movements of the carriage are limited by stop devices, which, as illustrated in Figs. 3 and 7, comprise a toothed stop bar 80, which is mounted on the carriage being secured .at its ends to the end bars 16. Adjustably mounted on said stop bar are margin stop devices comprising a bell trip 81, a line stop 82 and preferably two margin stops 83. These adjustable devices cooperate during endwise movements of the carriage with a rocking or stop member 84, which is mounted on the track-way 4 and is comprised in the train of line lock and bell ringing devices, the upper end of the rocking member 84 lying in the path of movement of the adjustable stop devices on the bar- 80. Said member 84 is screwed to a shaft -or bearing part 84 which takes bearings in lugs 85, which are secured to the front face'of the trackway 4. It will be observed that the margin stop devices comprise adjustable stops mounted on the carriage and the coiiperating stop 84 mounted on the trackway 4, and further it will be noted that when the trackway is removed from the machine it results in the removal also of the stop bar 80 with its stop devices and also of the coiiperating, rocking, device 84. The margin stop devices have the further function of preventing disconnection of the carriage from its trackway 4 when theparts are removed from the machine, so that they constitute a safety device for this purpose in case the stop devices 14, 15 should for any reason fail to work.

Step-by-step carriage feeding movements are caused through operating the printingkeys by escapement devices of suitable character, such for example as thosepartly illustrated in the drawings and described in detail and claimed in my Patent .No. 1,237,439 aforesaid. Said escapement'devices comprise a rackbar 86 mounted on the slide bar 12 (Figs. 5 and 7 Said rack bar is provided with two sets of teeth, one

meshing with a toothed wheel 87 mounted on the main frame and controlled by a spring drum which constantly urges the carriage leftward. The other set of teeth on the rack bar 86 co5perates with escapement devices proper that comprise a shaft 88 that has stationary bearings on the main frame and carries near its upper end a pinion 89, ca-

able of limited slidable movement on. the

responding ratchetteeth formed in the under face of the pinion 89. Fingers 93 projecting downward from the clutch member at opposite sides of the shaft slidably engage with notches cut in a flange 95 on said shaft, the construction being such that the clutch member is forced to turn always with the shaft. Key controlled devices mounted on the carriage engage in a circumferential groove 96 in the clutch member, and are operative to move said clutch member downward on the shaft to disengage the ratchet teeth on the clutch member from the ratchet teeth on the pinion 89 so as to permit said pinion to turn freely on the shaft 88, thus motor. I clutchmember is in opposition to a spring 97 coiled around the shaft 88 whichspring operates to maintain said clutch member normally engaged with the pinion 89 and also to restore said clutch member after the releasing operation. The lower end of the shaft 88 is provided with an escapement.

wheel which cotiperates with escapement dogs not herein shown but preferably of the character disclosed in my application Sr. No. 855,551. The releasing devices mounted on the carriage comprise spring releasing the carriage and permitting it to .run freely leftward under the pull of its The downward movement of the i to coiiperate with fingers 102 fixed to opposite ends of a releasing plate or bar 103 pivoted on the carriage. Said release bar 103 is loosely supported dJn a rod 104 which is secured at its ends to the bar 17 During endwise movements of the'carriage the bar l03fl slidably'cooperates with a beveled roller 105 which is mounted on a pin 106 carried by a lever member 107 having a stationary pivot 108. The inner end of said lever member carries a pin 109 which engages in the groove 96. The construction is such that when one of the release keys 100 and 101 bar 103 on its is pressed it operates to swing the release pivot, causing said bar through \the roller 105 to rock the lever member 107 its pivot 108, the pin 109 carried by said lever member acting on the clutch member 92 to release the pinion 89 as has been described'. It will be understood that when the carriage and its trackway are removed from the machine the releasing devices down to and including the bar 103 will also be removed while the cooperating parts from the roller 105 downward will remain on the machine frame.

My present invention embraces several important features and advantages some of which have not been claimed herein, 5. 6., those relating to the mounting of the carriage and platen, since they are included i in the subject-matter of my divisional application Serial No. 137,014, filed December Itwill further be understood that the principles of my invention by which I am enabled to provide a continuous supporting surface for a sheet of paper held substantially in a fiat position while it is introduced of the machine more particularly in connection with visible writing machines of the cylindrical platen style, are such that the .use of the invention is not confined to the particular arrangement or construction shown herein Various changes may be made without departingfrom my invention. 7
