Definitions

  • My present-invention relates to'an auxiliary front feed attachment for typewriting business machines, and is pri-' marily intended for carrying out book-keeping operations;
  • the main object of my present invention is to provide means permitting of properly introducing, in a comparatively simple manner, a from sheet which is to be written on.
  • Fig. 1 shows a perspective view of a portionof typewriter, known per se, provided with the attachment
  • Fig. 2 drawn to a larger scale represents a cross-section through the upper paper guide
  • Fig. 3 shows a portion of theguide plate in coaction with a fixed stop.
  • the carriage 1 which is movably guided on the typewriter frame, carries the platen 2 which is rotatable by means of two knobs 3, the sheet guide 4- (Fig. 2) associated with the lower platen zone, and thesheet-engaging and sheet-feeding rollers 5 and 6.
  • the latter through spring-loaded arms are supported on a common axle pin 7 and are swingable via an auxiliary arm (not shown) which is fixed to the shaft 8 and connected to an operating lever.
  • the sheet guide 4 is guided vertically movably (not shown) on a rod9.
  • Each upright 10 is rigidly secured to both ends of the carriage 1, only the left-hand upright being visible in Fig. 1.
  • Each upright 10 carries a horizontal pin 11 to receive a supporting crossbar which comprises a center piece 12 which through its bent-offend pieces is riveted to two arms 13.
  • the latter serve for detachably connecting the crossbar 12, 13 to the said two horizontal pins 11.
  • the arm 13 shown has a hole 14 (Fig. 2) for engaging the pin 11, whilst the second arm 13 (not shown) is recessed for engaging the second pin 11 (not shown) and has a pawl to be engaged with said pin in a notch provided thereon.
  • the web 12 of the cross bar has a lower portion which is bent-off forwardly so as to form two supporting lugs 15 of which only the left-hand one is visible in-Fig. 1.
  • Two parallel rods 16, 17 are mounted in the two lugs 15 in parallel relation to'the platen 2.
  • the numeral 19 designates a rearwall of that sheet-guide portion which is movable longitudinally of platen 2, being guided on the rods 16, 17 through brackets 21 which are secured to its: side-Walls 20. Between the two brackets 21 are disposed the-two rollers 18 which are of suitable length and which thus partake of the movements of slide 19-21.
  • the latter comprises moreover two front wall portions 22, 23 made of transparent material. Between these twoportions a central space-is left free, and the portions in a downward direction approach the rear wall 19.
  • To the left-hand bracket 21 (Fig. 1) is rigidly secured an upwardly projecting grip 24 which. serves for moving the. slide.19-2 1.
  • The, lat: ter is braced. on the upper edge. of, the cross bar web 12 2,731,125 i 'atehtd Jan. 17, 1956 by means of a top roller 25' (Fig. '2).
  • To the right-hand ends (Fig. 1) ofthe rods 16, 17" are secured toothed wheels (not shown) which mesh with each other.
  • the toothed wheel of the front rod 17 also meshes with a drive pinion 26 to which is-securedaknob27 by meansof which the two feed rollers lswmay be simultaneously rotated.
  • a fixed stop 28 formed by an angle and situated-within the range of, a part 29, which carries the conventional line scale, one leg of the angle stop 28 being rigidlysecured to said'part 29 or another-part.
  • the numeral'30 designates the ribbon close to the operating range of which the stop 28 is disposed.
  • the freeendjof the latter which is turned away from the platen 2, coactswith the lower longitudinal edge of a paper guide plate 31; which is elongated inthe direction of the platen.
  • the saidlower longitudinal edge of paper guide plate 31 comprises astraight portion 32 (Fig. 3) which via an inclinedportion 33 is connectedto a portion 34. The latter is set back from and much shorter than the portion 32 and extends parallel'thereto.
  • the angle enclosed by the two marginal portions 33, 34 is equal to thatenclosed by-the two legs of the anglestop 28.
  • the guide plate 31 which on its rear side has 'a line mark or control line 35, through its upper longitudinal margin is secured to a central piece 36 which, together with two side arms 37; forms a swing bracket.
  • Fig. 2 shows, in solid lines, that position of'theswingable guide plate in which the plate 31 is supported on the stop 28 through its lower marginal portion 32, and in dash-and-dot lines that position of the guide plate in which the plate 31 is supported on the stop 28 through its lower marginal portion34.
  • the lower edge of the plate '31 is spaced a considerable distance from the platen 2, but in-the second position only a little space is left between the guide plate and platen, so that at this point only a gap is left, namely an entrance for passing the sheet therethrough.
  • the cross bar 12, 13 as shown in Fig, 2 is supported-ontheplaten 2 through a roller 39 which isrotat-ably mountedon the rear side of the web12.
  • the guide plate 31 has to occupy the position shown in Fig, 2- in dash-and-dot lines in which its lower marginal portion 321's disposed close to the adjacent front margin of the lower sheet guide 4-, which facilitates the proper introduction of the sheet 0.
  • Such positionof the guide plate,31 is automatically given when the carriage 1 occupies a corresponding position in its track so that the 'p1ate 31 throughits set-back lower margin 34 is seated: on thestop 28.
  • the plate 31 in the-zone. of its lower margin 34 leaves free a typing field for the type-levers 40. Within the range of such field; the left-hand margin of the base or journalsheet a and also of'the account sheet b of which the margin is set back from that of sheet a may be typed upon by the type-levers.
  • the slide 19, 21 movable on the carrier cross bar i2, 13 may be set, longitudinally of web 12, alternatively to either of two relative positions, according to which setting position, With respect to its column, is desired for the front book-keeping sheet c relatively to the columns of the two other book-keeping sheets I) and a.
  • Such setting allows of performing book-keeping operations according to a particular system.
  • a hinged spacing rod (not shown) is disposed on the rear side of web 12. Said spacing rod contains notches for engaging the free end of the pin which carries the guide roller 25 (Fig. 2).
  • said spacing rod may be swung downwardly so as to disengage the said pin therefrom, whereupon the slide 19-21 through a tension spring is moved from one setting position to the other.
  • the slide li -21 by means of grip 24 provided thereon, may be moved in a direction opposite to the direction of said movement.
  • the attachment described may be mounted not only on existing typewriters but also on other business machines adapted for typewriting operations.
  • the attachment may be readily removed when not used.
