Application filed April 29, 1924. Serial No. 705,918.

My invention relates to paper feeding and controlling mechanism for typewriting machines and its general object is to provide new. and improved mechanism. of p the character stated. More specificallyv my inven tion liasi or'its object a provision of a very simple yet efiicient means for continuously advancing to predetermined extents greater than line space distances and thereafterarresting 'a work sheetor web. 3

I To the; above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations ofdevices, and arrangements of parts hereinafter described and particularly pointed out in the claims. I p I a H p In the present instance in carrying outmy invention 1 employ a support or cross bar on the carriage of a typewriting machine above the platen, and mount on said cross bar t-wo uprights or guide arms which carry paper controlling slides orblocks. These are limited in their sliding movements *by adjustable stops at the top of the guide arms and their front faces are roughenedtoprevent slipping of the paper or worksheet thereover during operations of the slides.

'After a line of writing is completed thetwo paper controlling slides are grasped-by the fingers'of the operator together with the side portions of the worksheet and are pulled up on the guide arms until arrested by the stops. The work sheet being clamped or. pressed against the slides and confined with them between the operators fingers is advanced a predetermined extent and an rested, beingthereby positioned to receive thenext. line of writing. On releasing the slides'they drop back to normal position according to the force of gravity. The slides in a sense act as stops in co operation with the fixed'stopson the guide arms- V 4 My invention will be described more in detail in connection with the accompanying drawingawherein I .Figurel is a fragmentary front-to-rear vertical sectional View showing the'carriage of aNo. 60 Smith Premier typewriting machine withmy invention applied thereto, the mounting of the carriage also beingshown. Figure 2 is a fragmentary front elevation of said carriage drawn to a somewhat smaller scale than Figure 1.. T

Figure 3 is a fragmentary sectional View taken on a plane designated by the section 'line l1 in Figure 2 and looking downward in'tl e direction ofthe arrows at said line.

F gures 4 and 5 are enlarged perspective vlews of details.

As will be understood from Figure 1, the,

top plate-'1 of themachine provides a support for goose-necked brackets 2 to which are secured by screws 3 oppositely grooved. guide ralls 4 and 5-, extending transversely of the machine and providing fixeditracke ways for the traveling carriage. Antifrictlon rollers 6 co-operate with the guide rails i and 5 and also with the rear bar 7 of theplat'en carriage or carrier, said rear bar being grooved along its top and bottom faces in correspondence with the guiderails. The carriage further. comprises end bars 8 fixed to the rear bar 7 at its ends and extending horizontally forward therefrom.- The end bars-provide bearings for theaxleforshaft 9 of arot'ary platenlO which is adaptedto be turned or rotated by the usual .finger wheels 11, and alsostep-by-step by line spacing devices J comprising a ratchet, wheel 12 connected tothe left-hand end of the platen, and a hand-actuated pawl 13. iCo-operative with the platen to advance or feed paper thereover when the platen is turned are re.

leasable feed rolls 14; and 15, the sections whereof are adapted-to protrude towards the platen through openings in a curved pa per deflector 16. Thefeed rollers are adapted to be thrown off by releasing mechanism comprising a hand controlled rock shaft 17.

Extending along the front of the platen below the printing line is a platen scale and guide 18'which is supported on the carriage.

cator, and paper guide 19 secured toastet'ionary support 20. extends. upward above the printing lineuand in front -of the scale 18. Theend bars 8 have integral'upward The printing A combined line finder, printing point indiextensions 8 which are connected by across are also omitted in the drawings. The parts above described are not new being found in the well-known No. 6O Smith Premier typewriting machine to which the preferred form ofmy invention herein shown is applied It; is to be understood however that vent slipping.

the invention is readily adaptable to other styles or makes of writing machines.

In carrying out the present form of my invention I make use of the rod or bar 21 as a support for a pair of carriers or brackets shown detached in Figure 5 and each comprising a hub portion 22 from which ex tends forwardly and slightly upward an arm 23 terminating in an inwardly off-set portion or extension 24. The hubs 22 are perforated to fit over and bear slidably on the rod 21. The rod is provided with a rib or spline 21 which co-operates with cut-outs indicated at 22 in the hubs 22 to prevent turning movements of the brackets'22-24 on the rod, while permitting the brackets to he slid thereon to desired positions of adjustment lengthwise of the platen. Set screws 25 threaded through the hubs 22 cooperate with the rod 21 to hold the brackets and the parts mounted thereon in adjusted positions. Riveted or otherwise secured to the rear faces of the extensions 24c are guide arms or track-ways 26 which extend upward from the brackets and slightly towards the rear. Said guide arms provide supports for rectangular blocks or slide pieces 27, each formed with a rectangular perforation in dicated at 28 (Fig. 4) to enable it to fit over its guide arm and slide freely up and down thereon. The front face of each slide or block is roughened or knurled as indicated at 29 to increasethefriction when the paper is pressedagainst the block and thus pre- Upward sliding movements of the blocks on the guide arms 26 are lim ited by stop members 30 arranged at the backs of the arms 26 and formed with elon-' gated slots 31 which receive screws 32 whereby the stops are adjustably secured in place near the tops of the arms and are enabled thus variably to limit upward movement of the devices 27. It will be seen that by reason of the extensions 24 being inwardly off-set towards each other, the parts 23 of the brackets will permit paper when desired to be advanced around the platen under the lower end of the off-sets 2a and be tween said arms.

In making use of my invention, a work sheet, as 33, is introduced into the machine at the rear and passes around the platen between it and the feed rollers 14 and 15 and full lines in Figure 1, in order to advance or sweep the sheet continuously and bring it to proper position for receiving the next line of typewriting, it is only necessary for the operator to press the sheet back against the slides 27 with his thumbs and to grasp the slides, thus clamping the paper against them and then to pull up on the slides. As

a result, the slides will be advanced together with the paper or work sheet, the latter being thereby fed continuously over the platen by the direct pull of the operator until arrested, as shown by dotted lines in Figure 1, through the contacting of the slides 'or stop devices with the cooperating stops 30 at the upper ends of the track-ways 26. On releasing the slides they will drop back under the action of gravity to normal position in contact with the top faces ofthe extensions 24. Usually it is preferable during contlnuous paper feeding operations to maintain the feed rollerslt and15 locked oil in released positions as shown by th? dotted lines in Figure 1, so that the paper may be advanced under the direct pull of the operator independently of turning movements of the platen and while it remains quiescent. Furthermore, under these circumstances the continuous advance is not restricted to exact multiples of line space distances. However, if desired, using my invention the paper may be advanced by the thereover under the direct pullof the operator, and also for variably limiting the feed ing orcontinuous advance of the paper so that it may be fed or spaced predetermined extents, the controlling means in the present instance comprising slides or grippers movable in restricted paths and restored to normal position under the action of gravity. By employing the hands of the operator to grip or connect the paper to the devices or slides, I am enabled to dispense with mechanical devices or gripping means. When mechanical clamps are employed, it is necessary to clamp and unclamp the paper by separate hand operations, or otherwise the clamps must move back and forth with the paper and stayconnected with it at all times. These disadvantages are avoided by the use of my invention. In the present instance the paper is normally free from the controlling means or slides, said means through the action of the operators hands being movable with the paper in one direction but mov ing in the opposite direction independently and automatically. As a result, convenient means are provided for movingethe work sheet step-by-step through distancesgreater thanline space distances;

My invention isparticularly useful in connection-withthe Writing of one-line checks or billsconnected together ina continuous strip or web during the writing-and afterwards separated; In such 'casesin order to advance the strip rapidly and continuously from one line to the next, the usual line spacing devices are inadequate, or at least inconvenientandmy invention provides an eX ing pre'ssed thereagainst by the hand: of the operator during the feeding operation effected by a pull on both the paper and the sliding means. i
