Application filed November 28, 1906. Serial 1'0. 345,511.

To all whom it may concern;

lie it known that I. THOMAS J. Goo, citizen of the Dominion of Canada, of the city of Toronto, in the county of York and Province of ()iitario Canada, have invented certain new and useful Improvements in Type- .Yriting l\lachines, of which the following is a specification.

My invention relates to typewriting machines and especially to means for controlling the paper in suchzmachines.

My invention has for its principal object to facilitate the controlling of the sheets of paper used in doing what is known as con dei-ised record work.

To this and other ends the invention con sists in the features of construction and coinbinations and arrangements of parts, all of which will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of the carriage of a typewriting machine having my invention embodied therein. Fig: 9. is an enlarged perspective view of a paper controlling device forming part of my construction. Fig. 3 is I a fragmentary top view of a catch for the feed rollrclease lever.

Fig. 4 is an enlarged end view of the upper rear part. of the typewriting machine with. the devices of my invention applied thereto. Fig. 5 is a similar view showing'some of the parts shown iii- Fig. l. but showing the feed rolls in their cast-oii' position.

In most of the figures of the drawings partshave been shown in section or broken away'or have been omitted as has been found convenient.

My invention may be readily adapted to various styles of typewriting machines, but I ha vc here shown it as applied to a Monarch v .)ewriter. This machine comprises a top plate 1 from which rise brackets or standards 2 to which grooved track-ways 3 are secured by screws 4. Anti-friction balls 5 cooperate with said grooved track-ways and avith oppositely grooved ways in a rcaror slide bar 6 forming part of the carriage or platen carrier of the machine. Said carri'age also comprises horizontal end bars or brackets 7 projecting forwardly from the ends of said slide bar and in which is jour-,

naled a cylindrical platen S. Said platen carries at its left-hand end a line space ratchet wheel 9 which is operated by a pawl 10 pivoted at 11 on an arm 12 opcratively connected to a rock shaft 13 which (Zlll'ltfi a line space handle or lever 11. The line space wheel 9 is controlled by the usual de-- tent mechanism (not shown). The llln: spacing mechanism is of the well known construction employed in tlie Monarch inachine, or. as far as my invention (011: cerned, said mechanism may be of any suitable description. The platen is also providedwith the usualfinger wheels t Pivoted at 15 in lugs 16 projecting for wardly from the rear. bar 6, are downwardly and forwardly extending arms 17 in which is mounted "a shaft 18 carrying the main feed rollers 19. Pivoted at 20 in the lower end portions of the arms 1. are small wheels 21 which are adapted to contact with arms 22 pivoted at in thelugs 16, said arms 1212 at their for-- ward ends carrying a feed roll shaft 21 on which are mounted one or more forward feed rollers Spring 2o. secured to the hanger arms l7, cooperate with lixed abutments 2? to press the feed roller 19 toward the platen, and springs '28. secured to the hanger arms 22, press the feed rollers 25 toward the platen. T he feed rollers protrude through suitable openings in a paper apron 29 which extends from side to side of the machine beneath and at the roar of the platen, and which at its rear edge .providedwith parts 30 bcmloosely aronndia shaft 31 which is journaled in the end bars 7 of the carriage, the construction being such that the paper apron is free to sawing up and down about said shaft. Said paper apron is normally held close to theplaten as shown in Fig.1 by flat springs 32 secured to the upper sides of the arms v Theshaft 31 forms part of a feed roll release device which is operated by an arm- The feed rolls are released by drawing aid 105 handle toward the front or the machine in which direction its motion is limited by an. arm on "he handle engaging Ilitflittll) pin )3 has :1 10d 36. Each of the hanger arms 17 has pro-' jcciing from its upper forward side a pin 38, the end of whichis beveled off for coacting on the pins or lugs 38, press the arms 17 away from the platen against the tension of the springs 26. At the same time the .rollers 21 depress the arms 22 against the tension of the springs 28 and thus move the forward feed roll away from the platen. The springs 32 moving with the arms 22 no longer hold'the paper apron 29 against the platen and said paper apron accordingly drops by its own weight to the position shown in Fig. 5. The machine is also equipped witha scale plate 40 ('Fig. 4) which is spring-pressed toward the platen in the usual manner. The parts thus far described are similar to the parts heretofore used in the Monarch typewriter.

For the purposes of my invention it is sirable that when the. handle 33 is drawn .forward, it be retained in that position so as one end of a frame rod to the platen frame as will hereinafter more clearly appear. The spring plate 41 carries at its rearend a beveled pin 43 which is adapted to snap in behind the arm as shown in Figs. 3 and The rear end of the spring 41 is bent ofi at an angle as shown at 44 in order to increase the length of the beveled surface by means of which the arm 33 presses the spring 41 toward the right when said arm is drawn toward the front of the machine. When it is desired to release the handle 33, the spring 41 may be pressed toward the right by the finger of the operator, whereupon the springs 26 and 28 Will restore the feed rolls and paper apron to" operative position. In assembling the machine the handle 33 is drawn forward to its releasing position, shown in Fig. 5, and the spring catch 41 is adjusted by turning it u or down about the screw 42 as a pivot unti the pin 43 is in position to hold the handle 33 in said releasing position, after which the screw 42 is tightened to retain the catch in its adjusted position.

My invention comprises paper fingers or paper ,c-ontrolling. devices coiiperating with the front face of the platen to control a comparutivelv wide record sheet and carbon sheet and se )arate controlling devices cooperatingwit the front face of the platen to control a comparatively narrow bill sheet.

These several paper fingers are mounted on the supporting or frame rod 45, hereinbefore referred to, which connects the two end bars -7 of the carriage, passing about the platen.

Said frame rod is mounted at its ends in brackets 46, rising from the end bars 7 and said frame rod is secured in place by headed 45 has a longitudinal groove 47 therein, in-

which groove lies an internal spline 48 of a sleeve-like hub 50 of an arm 51 of the support for the paper fingers'for one end of the platen. The construction is such that the support may be adjusted lengthwise of the platen from end to end thereof by sliding it along the rod 45, butit cannot turn about said rod. One of these supports and the paper controlling devices mounted thereon is shown in Fig. 2 and the other support is similar to it except that the parts are reversed for coiiperation with the other end of the platen and the same, reference letters are applied to these devices at both ends of the platen. The forward end of each arm 51 is formed into a head 52 to which are pivoted at the two'arms-of a bifurcated, block-like arm 54 on which is mounted a small roller The head 52 is formed with two faces at an angle with each other for coiiperation with a spring-pressed plunger seated in the arm 54 and pressed toward the head The construction is such that when the arm 54 is turned downward the plunger 56, cooperating with the lower one of the two faces 5250f the head 52, presses the roller against the paper, but if the arm 54 be raised by the. operator until the plunger 56 passes the angle between the two faces 52 of the head 52, said plunger serves to retain the arm in an elevated position in which the roller is held away from the platen. The roller has an elongated hub 57 that is journaled on a headed screw 58 that is threaded into one side of the arm 54. Each paper finger for the wide sheet of paper comprises a plate-likeguiding portion 60 mounted on an arm 61- pivoted at 62 to the associated supporting arm 51, and each guiding portion 60 is apertured at 60 to permit'the associated roller to bear against the paper as it passes under the guide.

For cooperation with the narrow sheet of paper or bill sheet there is an auxiliary paper controlling device comprising a roller 63. the elon ated hub 64 of which is journaledon a headed. screw 65 threaded into one side of an arm 66 which is or may be substantially like. the arm 54 above described. Said arm 66 is bifurcated and pivoted at 67 to a head 68 that is mounted on the inner. end of a rod 70 that extends longitudinally of the platen and passes freely through an opening in the supporting arm .sition independently of the other.

j mg arm 5'1 andgalsot-hat either of the paper reference to doing condensed record work.

' said Fig. 1; that is to say, the record sheet- 51 so that said rod may be adjusted lengthi wise of the platen by sliding it through said supporting arm. The rod is retained 111 its adjusted position by a set screw '71 threaded into the arm 51 and at its inner end engaging said rod 70. The arm 66 is provided with a springspressed plunger 72 which cooperates with'the angled faces of the head 68 in the same manner as theplunger 56 with the'head 52, the construction being such that-the arm 66 may beswung up or down about its pivot 67 bringing it out of or into operative position, and said arm will be retained in either of said positions by saidspring-plunger. The sleeve 7-0 and supporting arm 51 are slida-ble longitudinally of the f ame rod 45, whereby both paper fingers may be adjusted together lengthwise of the platen. It will be understood that the two paper controlling devices may thus be adjusted together and that the I auxiliary paper controlling device is also independently adjust-able lengthwise of the platen by slidingthe rod 7 0 in the supportfingersmay'be elevated out of operative p0 It will also lie-understood that the same'manipulallOlkUft-llflPE-ItS is possible at both ends of the platen.

My'invention is designed with especial 'In doing this work bills are written'on the typewriting machine on comparatively small sheets of paper which are hereinafter called billsheets and a condensed record of everything written by the typewriting machine on these bill sheets is made by carbon paper on larger sheets of paper which are herein called record sheets. The matter written on' any one bill sheet may consist of only a few lines and it is the purpose of the present invention to facilitate the duplicating of this :matl'er on the record sheet, a short and uniform space being left between successive records.

In Fig. l the paper is shown in place in the machine ready. for use, 73 designating the romparativelvwide record sheet, 74a heetof (iltlHHl paper also comparatively wide. and T3 the bill sheet which is copiparativelynarrow and which usually comparaiively short. In said Fig 1 the several sheets of paper are shown about in the position they occupy at the beginning of a new bill sheet and a new record sheet, the bill sheet shown in the machine being the first of several to -be duplicated on the record sheet 7 by means of the carbon sheet H. i The several sheets of paper are placed in the machine in about the position shown in is placed appropriately for writing the first line thereof and the bill sheetis adjusted in the .machine so that the first writing line thereof is at the line of writing-in the mai chine. although in practice the bill sheet is generally given a lead over the record and carbon sheets in order to bring the first line reproduced on the record sheet near the top thereof. The sheets of paper may be brought to this position all together, or the record sheet and carbon sheet may be suitably positioned in the machine and the bill sheet be inserted afterward and independently adjusted. Each of the paper controlling deyices comprising the plate 60 and roller is then adjusted for suitable cooperation wit-h the'record sheet and carbon sheet and so that it will not cooperate with the bill sheet The set screws 71 are loosened and the paper controlling devices comprising the rollers 63 for the bill sheet, are then adjusted longitudinally of the platen for I proper cooperation with said bill sheet. The

parts being adjusted and the paper being in proper position the bill is wrltten, the platen bein turned for the necessar line 5 210111 and all three of the sheets of paper being fed together until the bill is completed. The platen is then rotated adistance suitable for the spacing between two of the records on the record sheet or for providing a suitable space between the last writtenline of one bill reproduced on the record sheet and the first line of the next bill to be reproduced on said sheet. This isnsually done by operating the line spacing lever 14 twice. The handle 33 is then drawn toward the front of the machine until it is caught bythe spring catch 41 and retained in that position with the feed rolls 19 and 25 and paper apron 29 held away from the platen.- The two rollers (33 are then moved upward to their inoperative positions, thus entirely freeing the bill sheet 75 from the paper controlling devices, but leaving the record and carbon sheets still held by the paper fingers 60, it being.

understood that the light pressure which 'inay be exerted bythe paper scale 40 is insufficlent to have any appreciable effect on the bill sheet. The top of the bill sheet may now be grasped by the fingers and withdrawn from the machine without disturbing the record and carbon sheets which are held in position against the platen by thepaper fingers 66 and rollers A new bill sheet is then inserted in the machine from the back of the platen, its forward edge being guided by the paper apron 29. This sheetis pushed forward until its leading edge appears above the scale plate when said lead-' ing edge may be. grasped bv the fingers and the bill sheet be adjusted to bring the first writing line thereof to the printing point. the record sheet and carbon sheet being still retained in the position in which they were left before the first'bill sheet was removed from the machine. hen the new bill sheet is properly adjusted the rollers 63 are snapped down against it and the spring catch 41 is released, permitting the feed rollers 19 and 25 and the paper apron to return to operative posit-ion. The new bill isfthen written on the new bill sheet and duplicated in its proper place on the record sheet, after which the line-spacing handle 14 is again operated to space between records and the, second bil sheet is removed from.

There is thus nothing about my attachments to obstruct the vision of the operator, it being understood that the rollers 63 cooperate with the bill sheet at or near the side margins thereof and preferably beyond the printing field.

From the foregoing description will be seen that the axes of the rollers and 63 are coincident and parallel to the axis of the platen; that said rollers are situated indifferent planes which extend transversely of the platen, so that the rollers 63 may cooperate with sheets of one width, whereas the rollers 55 and the paper'fingers may cooperate with a sheet or sheets of a different width and not with the sheet controlled by the rollers 63 and that the rollers 55 and 63 cooperate with the paper after it passes the printing line and are located in front of the platen and above the printing line. It will also be seen that my invention may be applied to the Monarch machine without changing the structural features of that machine. I v

Various changes may be made in the details of construction and arrangement without departing from my invention;
