Definitions

  • Our invention relates to typewriters and more especially to bookkeeping machines.
  • a sheet of paper known as t e audit sheet is permanently carried on the' platen and the matter which is being typed on forms such as statements of account, etc. is copied on the audit sheet.
  • One of the sets is constituted by the usual l rollson the paper guide rod which are adapt ⁇ ed to be displaced on the rod for holding audit sheets of various widths.
  • the other set is constituted by a plurality of resiliently supported-rolls in a rail which is Afulcrumed in the side walls of the paper carriage.
  • the audit sheet When it is desired to insert a form and the paper feedrolls below the platen have been lifted, the audit sheet is firmly held on the platen by the rolls of the first set, (the v rolls on-the paper guide bar) so that the auditsheet cannot move. on the platen notwithstandingits being released by the feed rolls.
  • the rail with the other set After the first set has been brought to bear on the platen as described, the rail with the other set is rocked so as to lift the rolls ofthe second set from theplaten in order" to permit insertion of the form.
  • the pins are secured to springs to enable them to yield when forms are extracted, or ositive means like a cam shaft may be provlded for withdrawing pins which would be in the way.
  • Fig. 2 is a similar view showing the other end of the: platen and its .accessories'in theposition in which the first set of rolls is applied to the platen.
  • Fig. 3 is a section on the line.3-3 in Fig. 1,
  • Fig. 4 is a section on the line 4 4 in Fig. 2,
  • FIG. 5-8 illustrate the mechanism for aligning perforated forms as referred to above
  • Fig. 5 being a cross section of the platen shlvingl the sets of rolls inthe same position as 1g.
  • Fig. 6 being an elevation of the straightedge supporting the pins viewed from the left in Fig. 5, and f Figs. 7 and 8 being sections on the lines Y 7-7 nd 8-8 in Fig. 6, respectively, drawn to a larger scale.
  • l0 are the. sides of the platen carriage which are connected at the rear by a stay 8
  • l is the platen
  • 1 and 1 are the usualy knurled handles for rotating the platen
  • 2 is the usual lower paper.
  • 5 is the usual paper guide bar
  • 6, 6 are the rolls of the first set which are adapted to be displaced axially-on the guide bar for the purpose mentioned.
  • the guide bar is arranged to rock about the stay 8 by means of two arms 7, 7.
  • 17, 17 are links fulcrumed on the ends of the bar 5 beyond the arms 7, 16, 16 are arms which are pivotally connected with the links 17 at 16', and 9 is a'scctioned rail which is secured to one of the arms 16 at either end and is fulcrumed in the sides 10 by trunnions 9a.
  • the rail comprises a straight lower part 9b and a curved upper part 90.
  • 11, 11 are curved plate vsprings which are secured to the base of the curved section 9c by rivets 11 (Fig. 1).
  • the free ends of the springs are turned up and perforated to support trunnions at the ends of rolls l2 which constitute the second set.
  • 13 is a bar extending in parallel tothe lower straight section of the rail 9, and 14 is a stop which is adapted to be displaced onY the bar for aligning the forms laterally. Any number of stops may be, provided.
  • the parts In operation with a form b inserted above the audit sheet a, the parts are in the position illustratedv in Fig. 3, in which the paper Y guide rod 5 with the first set of rolls 6 is in its upper final position and the second set of rolls, 12, exerts pressure n the form and the audit sheet.
  • the springs 18 are under tension andholdthe rolls 12 firmly applied onto the form and the sheet while the rolls 12 arei applied to the form b under resilient pressure by their own plate springs 11.
  • the rail 9 is rockedyabout its trunnions 9a, so that the rolls 12 of the second set are lifted from the platen 1 and the lower edge of the straight rail section 9b is moved so as to indicate the proper position of the form b in vertical direction.
  • the form is aligned by the stop or stops 14.
  • the springs 18 are also under tension and hold the bar 5 with the rolls 6, 6 firmly to the platen 1.
  • the inner face of the straight section 9b serves as a guide for the form b while it is being inserted.
  • edge 31 by rivets 36 are three U-shaped springs 35, 35 and 35, one at'each end and the third in a central position, but any other number of springs may be provided, if desired.
  • Each spring i-s provided with a pin 37, 37 and 37 respectively, which pins are adapted to project from the front face of the straight-edge 31 through perforations in the straight-edge so as to enter the corresponding perforations in the forms.
  • the springs which tend to withdraw the pins from the perforations ' are under the control of a cam shaft 39 with a handle 40 at one end which is carried to rotate ⁇ in the brackets 32, and is also adapted to be displaced axially in such bearings for al purpose which will presently be described.
  • the cam shaft 39 is provided with notches 38 in line with each spring.
  • the cam shaft 39 is displaced axially so as to place the notch 41 opposite the central spring 35.
  • the notches 38 are wider than the notch 41 so that they will remain in operative position with respect y to their springs notwithstandingth axial displacement of the cam shaft 39.
