Definitions

  • ThisY invention relates generally to improvements in typewriting machines, but more'specifically to a billing device employed in connection with and forming a part' of a 5 typewriting machine.
  • the principal object of the present invention is to provide a manually operable means which will separate the pressure feed rolls from the platen for the purpose of initially inserting the book sheet, carbon, and the first invoice, and for subsequently inserting other invoices, and to provide a separate manually operable means which cooperates with the pressure rolls releasing means for effecting a line spacing operation at the completion of a printing operation whereby the book sheet will be line spaced and certain feed pressure with to permit the ready withdrawal of the printed invoice and the ready insertion of y a new invoice, both of said means upon release by the operator being returned automatically to their initial positions after the insertion of the new invoice.
  • Figure 1 is a front elevation of a typewriter carriage embodying the subject matter of my invention
  • Figure 7 is a perspective view of the l manually controlled lever of the mechanism for releasing the pressure rolls.
  • Figure 8 is a perspective view of the manually controlled line spacing lever.
  • the machine includes a carriage A having end plates 5 and a platen B fixed to shaft 6 which are respectively journaled in said end plates.
  • the carriage includes ⁇ on its left side the ⁇ usual line spacing means (not shown) which is employed where the usual single line spacing is re uired between separate items on invoices.
  • uch line spacing means may be constructed in accordance with the Hess and Myers Patent 1,427,468, August 29, 1922.
  • Front pressure rolls 7 which are 1n the form' of sleevesv areloosely fitted on a rod 8 extending parallel with the platen. Obviously one or more rolls may be employed as desired.
  • the rod 8 is supported on the forwardly extending arms 9 of bell-crank levers 10 which are pivoted at their angles as at 1l to the carriage A;
  • the rearwardly extending arms 12 respectively engage in cam grooves 13 which extend transversely of an oscillating or rock shaft 14, and bear against the respective bottom or eccentric surfaces 15 formed by said grooves, as shown in Figure 5.
  • Coil springs 16 are each connected' at one end as at 17 to the forwardly extending arm 9 of the bell crank lever 10, and at its other end to a pin 18 fixed to the carriage A..
  • a fiat spring 23 is connected at one end to the carriage A and has its free end bearing on the arm 20 to normally and yieldably retain the rear pressure roll 19 in contact with the platen.
  • the rock shaft 14 will be oscillated in a direction to release simultaneously the pressure rolls 7 and 19 from contact with the platen, and upon release of said lever by the operator the springs 16 and 23 will automaticalo ly return all of the parts to their initial positions.
  • a line spacing ratchet wheel 28 Fixed to the platen shaft 6 is a line spacing ratchet wheel 28, and journaled 011 said shaft is a bell crank lever 29 having arms 30 and 31.
  • a ratchet do or pawl 32 is pivoted as at 33 to the arm 30 or engagement with the ratchet wheel 28, and a spring 34 functions to urge the dog into engagement with said Wheel.
  • a manually operable lever 35 is provided at its pivot end with a laterally extending hub 36 which is journaled on the pivot screw 25.
  • a forwardly extending rock arm 37 is fixed to the hub 36 and a link 38 is pivotally connected at one end as at 39 to the arm 31 of the bell crank lever 29 and at its other end as at 4() to the rock arm 37.
  • the lever 35 is provi ed with a laterally extending pin 41 which is disposed in rear of the lever 24 and is adapted to engagel the said lever and move the same forwardly when the lever 35 is moved forwardly, thus effecting a line spacing operation and a pressure roll releasing operation.
  • a link 42 is pivoted at one end as at 43 to the pressure roll releasing lever 24 and is provided at its other end with an elongated and arcuate slot- 44 through which a guide screw 45 passes, the screw being mounted on the carriage A eccentrically relative to the travel of the pin 41 and functioning to guide the link in its endwise movement upon oscillation of the lever 24.
  • the link 42 is provided With a depending projection or tooth 46 at a point adjacent the pivot 43 of the link but slightly in rear thereof.
  • a table or .support 47 of usual construction is mounted on the carriage Ain rear of the platen B and a separating plate 48 is supported on the carriage and acts as a guide and separating plate for the sales, journal or book sheet.
  • the lever 24 is first moved forwardly to release the pressure rolls 7 and 19 from the platen.
  • a journal or book sheet C is then inserted around the platen between the platen, and the separating plate 48 and pressure rolls 7 and 19.
