Definitions

  • My invention relates to a carbon supporting at tachment for typewriters and means of feeding" carbon webs and paper webs in superimposed rea r lationship so that the same carbon webs can be used with a large number of successive sections supporting, supplying and Withdrawing carbon of paper webs.
  • my method consists of the following:
  • Figure 1 is a top plan view of atypewriter with l the attachment involving my invention applied thereto; V
  • Figure 2 is a plan view of the attachment with the carbon sheets removed showing the engaging mechanism for applying friction on the sheets of .7 paper to causethe carbon sheets to travel with
  • Figure 3 is a side elevation of the typewriter-and attachment showing thecarbon sheets in position Where they are being fed with the paper sheets during, the writing operation ;f 20
  • Figure 4 is a section through the carbon sheets and the paper sheets and the means of suspending the carbon sheets between the paper sheets;
  • Figure5 is a perspective of one corner of the carbon sheets and the strip for supporting them; i 5

  • Figure 9 is a section on the line 99 of Figure 2showing the arrangement of the roller on which the tape is wound and the spring which actuates the o er; 7 l a Figure i0 is 'ajfront elevation of the, mecha nism showing the position ot the carbon sheets and the paper sheets at the beginning of the writing operation; g
  • FIG. 11 is a side elevationthereof
  • Figure 12 is a front elevation showing the 4 sheets at the end of the operation of typewritin l v i Figure l3'is a side elevation thereof;
  • Figure 114 is'a front elevation showing theposition of the carbon sheets and paper sheets when they have been moved backwardly so as to'release the carbon sheets after having types writtenupon the paper sheets so that the carbon sheets can return to their initial position;
  • Figure 15 is a side elevation of Figure 14;
  • FIG. 18 is a side elevation of Figure 17.
  • I is a 'typewriter havingt'the usual cylindrical platen 2 actuated by the hand wheel 3 through the shaft 4..
  • the remainder of the construction of the typewriter is standard, such as the" typewriter ribbon 5, on which the type facedmpinges, the typeface being eliminated inthe drawings for the purpose of clarity, but making it's'impression at the point indicated at 6 in the usual'manner.
  • the pressure roller 1 fAssociated "with the platen "Z is thepressure roller 1. "Mounted upon the typewriter'fram'e 8 is theframe supporting the apparatusof this invention, which can be detachably attached to any'standard typewriter. 4 This frame comprises side plates 9 and III, the “lowerends of which are slotted as at II for mounting upon the cross bar I2 of the typewriter.” The upperends of the side bars 9 and “are connected by a rod' I3 having guide members I4 on either end thereof for guiding a pluralityof continuous paper sheets, of which there are 4 shown in superimposed relationship and designated l5, l6, l1 and I8. These sheets are supplied from either'a'roll or a pack l9.
  • axle is spring actuated by the ,spring'25iastened' at one end 26 within the drum Z'i'which'is stationarilymounted upon the side plate 10 and the other end at 28 is mounted within the axle 2'0 which carries thewinding drums 2ljand 22.
  • the framei's provided with across member 39 It is also provided with a rocking rack 40 carrying apressure member 4! which has a handle 42.
  • a pressure member 4! which has a handle 42. Thisisused, as'will be later described, for applying pressure to the surface of the paper sheets and the interleaved carbon sheets to cause the, groups of sheets to frictionally engage and to travel together until the combined carbon sheets and paper sheets can be engaged by the pressure roller 7 and its platen 2 to insure continuity of feed oi the two groups of sheets as a unit.
  • carbon sheets may be drawn upwardly without 1 moving theflpaper sheets when the carbon sheets are released from the pressure between the pressure roller 1 and. the platen 2, all as will be hereinafter described in connection with the method of operation of this invention.
  • I provide a notched sprmg plate .,3 0 a"whichcan be inserted in any one of the notches 32 in order to yieldingly and tightly hold the cardboard supports 33 in close superimposed relationship one on the other on top of the main support 29 which iscarried by the tapes.
  • the frame has two inwardly-disposed guiding plates 43 and 44 which are connected at their upper ends to the rod Is and at their lower ends to the cross rod 45.
  • the paper sheets are provided with a plurality of superimposed forms generally designated 46 which must be maintained in superimposed condition with the carbon paper between them so that the type of the typewriter or other means may make duplicate impressions on all of the sheets.
  • These forms are separated by transverse perforations which are also in the respective sheets superimposed one over the other.
  • the combined carbon and paper sheets move up.- wardly into the dotted line position indicated at 49'beneath'the guide roller 50.. This serves to draw the carbon sheets down with the paper sheets against the resistance of the spring 25.
  • the combined carbon and paper sheets may assume the position shownat 4B or they maybe in the position shown at 49 as the operator may prefer. In either event, the typewriting has been completed and the duplicate items have been" entered on the superimposed sheets-l5; I6, I1 and 18 through the agency of the typewriter ribbon 5 and the carbon sheets 35, 31 and 38.
  • the pressure member 4! is applied, as in Figures 17 and 18, to cause the carbon sheets to travel with the paper sheets for the next set of formswhen the carbon sheets are between the new forms until the carbon sheets, the ends of which are indicated in Figures 17 and 18, as at 52, can get between the pressure roller 7 and the platen 2 and can be carried by reason of such pressure upwardly to the writing position shown in, Figures 10 and 11 for the repetition of another operation.
  • the tension of the spring can be adjusted by any well known means to vary the pull according to the number of copies, as by tightening the coils on the spring, or other means.
  • Patent is:
  • a frame means of guiding a plurality of superimposed paper sheets over said frame, a carrier for a plurality of carbon sheets, a spring roller having cables wound there- 'on connected to said carbon sheet carrier, said roller, cables at either end thereof wound thereon, a supporting plate connected to the ends of said cables, studs on said supporting plate, a plurality of supporting strips and carbon sheets mounted on each strip mounted on said studs interleaved between the paper sheets and a spring covr plate mounted on said studs over the top of the top paper sheet.
  • SQL combination means of supporting carbon'sheets comprising a back plate spring acv tuated support, cables at either end thereof,
  • a typewriter having a platen and a pressure roller, a frame supported at one end on said typewriter and extending upwardly above said typewriter for feeding a pluralityof paper sheets downwardly and between the platen and the pressure roller, means on the other end of the frame for suspending on the frame between the paper sheets relatively short carbon sheets, yielding drum means forming a part of said suspension means for resisting the downward movement of the carbon sheets with the paper sheets when frictionally engaged, mechanical means associated with the frame for causing said frictional engagement so that the carbon sheets and paper sheets will travel together until frictionally engaged by the platen and the pressure roller, said yielding means being adapted, when the frictional engagement of the several means is released, to withdraw the carbon sheets backwardly between the paper sheets.
  • means to support a plurality of superimposed strips of paper means to support a plurality of carbon sheets interleaved between the strips, said means comprising a plate having at each end a notched studand means on the studs for separately holding the carbon sheets, a spring strip adapted to engage the studs in the notches, and a tape attached at one end to each end of the plate for supporting and moving the plate.
