Definitions

  • This 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 typewriting machine.
  • the principal object of the present invention is to provide means including a manu ally operable lever which during movement of the lever will successively efiect a line spacing operation and a release of said pressure rolls whereby the book sheet will be line spaced and the pressure rolls will be immediately thereafter released to permit the ready withdrawal of the printed invoice and carbon and the ready insertion of a new invoice and carbon, the return movement of the operating lever eiiecting the return of the pressure rolls to operative position, without however effecting the line spacing mechanism.
  • a further object of the invention lies in the provision of a second manually operable lever for releasing the pressure rolls only and movable entirely independent of the lever which effects the successive line spacing operation and the release of the pressure rolls, thus permitting the invoice to be adjusted properly with respect to the book sheet.
  • Figure 1 is a front elevation of a typewriter carriage embodying the subject matter of my invention
  • Figure 2 is an end elevation thereof, the parts being in normal position
  • Figure 3 is a similar view, but showing the platen at the end of a line spacing movement and also showing the pressure rolls released from the platen,
  • FIG. 1 is a detail sectional view showing the means for supporting the pressure rolls
  • Figure 5 is a detail elevation showing adjustable means for varying the line spacing movement of the platen
  • Figure 6 is a perspective view of the arm which supports the line spacing pawl
  • Figure 7 is a perspective view of the latch associated with the line spacing mechanism
  • Figure 8 is a perspective view of the lever for effecting in succession the line spacing operation and the release of the pressure rolls
  • Figure 9 is a detail elevation showing the second manually operable lever and its relation to the means for releasing the pressure rolls, and
  • Figure 10 is an elevation of a pinion.
  • the machine includes a carriage A having end plates 5 and a platen B having axles 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 required between separate items on invoices.
  • line spacing means may be constructed in accordance with the Hess & Myers Patent 1,127,468. Aug. 29, 1922.
  • Front pressure rolls 7. which are in the form of sleeves. are loosely titted on a rod 8 extending parallel with the platen. Obviously one or more rolls 7 may be employed as desired.
  • the rod 8 is supported on the forwardly extending arms 9 of hell crank levers 10 which are pivoted at their angles as at 11 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 4.
  • 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.
  • rear pressure roll 19 has its ends journaled in lever arms 20, one only being shown, which have their rear ends pivoted as at 21 to the carriage A.
  • the free ends of the arms 20 are each engaged in a cam groove which extends transversely of the rock shaft 14, and bears against the bottom or eccentric surface 22 formed by said groove, as shown in Figure 4.
  • a flat 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 cam surfaces 22 will swing the lever arm 20 against the tension of the spring 23 and thereby release or separate the rear pressure roll from the platen.
  • the axle 6 on the right hand end of the earriage projects beyond the end plate 5 and a bracket 28 is loosely mounted on the projecting portion of the axle 6.
  • This bracket includes a plate 29 and upper and lower plates 30 and 31 respectively, the plates 30 and 31 being disposed in the same vertical plane and being united with the plate 29 through the medium of a connecting portion 32, the bracket 28 being held against rotary movement when the platen is turned, by means of a rod 33 whiehconnects the end plate 5 and the plate 29 of said bracket.
  • a combined line spacing and pressure roll releasing lever 34 is pivotally mounted on the axle 6 adjacent the plates 30 and 31 of the bracket 28. Also journaled .A
  • a pawl or supporting arm 35 on the axle 6 is a pawl or supporting arm 35, and to the outer end of this arm is pivotally connected as at 36 one end of a pawl 37 adapted to engage a ratchet wheel 38 fixed to the axle 6 of the platen.
  • a coil spring 39 has one end connected to the pawl 37 and the other end connected to the arm 35 for yieldably urging the pawl into engagement with the ratchet wheel 38.
  • a stop, 40 as shown in Figures 1 and 5, extends laterally from the front edge of the plate 29 of the bracket 28 and serves to limit the downward movement of the arm 35.
  • a latch 41' is pivotally connected intermediate it-s ends as at 42 to the lever 34. One end of the latch 41 provided in its under surface with a cutout forming a resultant shoulder 44.
  • the cutout 43 is normally adapted to embrace a pin 45 which is angular in cross-section and extends laterally from the pawl supporting arm 35, the shoulder 44 cooperating with the pin to normally connect the arm 35 with the lever 34.
  • a coil spring 46 is connected at one end to a pin 47 fixed to the lever 34 and at its other end to a pin 48 fixed to the end of the latch 41 at a point adjacent the shoulder 44. This spring 46 functions to yieldably retain the latch in engagement with the pin 45. It will be observed that as long as the latch 41 is connected with the pin 45, the pawl 37 will be moved rearwardly with the lever 34 in order to bring about a line spacing operation to the platen.
  • a shield 51 for the pawl 37 is provided with a supporting flange having an arcuate slot 53 formed therein. Screws 54 extend through the slot and engage threaded openings in the plate 29 of the bracket 28. By means of this pin and slot connection between the bracket and the shield, the latter may be adjusted relative to the pawl and thereby vary the time when the pawl 37 en gages the ratchet wheel 38.
  • the flange 52 is formed on its lower edge with a series of ratchet teeth 55 which are engageable with a retaining pawl 56 pivoted on the plate 29 as at 57 and yieldably held in engagement with the teeth by a spring 58.
  • This gear 65 is normally in mesh with the gear 63, and is provided with a projection or finger 67 which is located within the cutout 59 of the lever 34.
  • the shoulders 60 and 61 will alternately engage the projection 67 and thereby oscillate the gear 65 which in turn will oscillate the gear 63, the arm 62, the gear 27, and consequently the rock shaft 14:.
  • the lever 34 in its forward direction of movement will release the pressure rolls 7 and 19, and in the opposite direction of move ment will permit said rolls to return to their platen engaging position.
  • the shoulders 60 and 61 are spaced apart a distance so that upon the rear movement of the lever 3% the shoulder 61 will not engage the projection 67 until after the latch 41 has been released from the line spacing mechanism and consequently the pressure rolls 7 and 19 will be released only after the completion of the line spacing operation.
  • Rolls 68 are rotatably mounted on a graduated rod 69 which is secured at its ends to the swinging bail arms 70. These rolls are also supported on the rod for independent adj ustment therealong.
  • the arms 70 are pivoted as at 71 to the end plates 5 of the carriage A.
  • a coil spring 72 which is connected at one end to each bail arm 70 and at its other end to the end plate of the carriage, functions to yieldably retain the rolls 68 against the platen B.
  • These rolls 68 are the means for holding the journal or book sheet 0 in position when the other two sets of feed rolls 7 and 19 are released for the insertion and removal of the invoices, thus permitting the retention of the book sheet in the line space position where the last entry was made subsequent to the rotation of the platen and feed rolls preparatory to removing the invoices.
  • the lever 24 is first moved forwardly to release the pressure rolls 7 and 19 from the platen.
  • the journal or book sheet 0 is then inserted around the platen between the platen, and the separating plate 73 and the pressure rolls 7,19 and 68.
  • An invoice or billhead E and carbon sheet D are then inserted between the separating plate 73 and the table or support 74. and between the hook sheet C and the pressure rolls 7, 19 and in front of the rolls 68.
  • the lever 21 is then released by the operator and this lever together with the pressure rolls 7 and 19, then return to their initial positions.
  • the desired entries are then printed on the invoice E and simultaneously on the record or book sheet C.
  • the lever 34 is then moved rearwardly to first efifect a line spacing operation to the book sheet C and to subsequently effect a release of the pressure rolls 7 and 19 during the continued rearward movement of said lever.
  • the printed invoice E together with the carbon D are then removed, a new invoice and carbon are then inserted and the lever 3% moved forwardly to its initial position. This operation is repeated as often as desired and as a result the line spacing operation after each invoice is completed, the entries on the book sheet are spaced uniformly apart.
  • a line spacing mechanism associated with said platen including a ratchet wheel fixed to the platen, an arm pivoted to swing about an axis concentric with the axis of the. platen, a spring pressed dog mounted on said arm for cooperation with the ratchet wheel.
  • a line spacing mechanism associated with said platen including a ratchet wheel fixed to the platen, an arm pivoted to swing about an axis concentric with the axis of the platen, a spring pressed dog mounted on said arm for cooperation with the ratchet wheel, an operating lever, a latch pivoted on the lever and normally connected to said arm, a fixed abutment engagcable by the latch to disconnect the latter from the arm upon a predetermined movement in one direction of the operating lever, and means operative by the lever subsequent to the release of said latch for releasing said pressure rolls during movement of the lever in the same direction.
  • a typewriting machine the combination with a platen, of releasable pressure rolls cooperating therewith, means for releasing said rolls including a cam shaft, and a gear fixed thereto and provided with an axially extending arm provided with a gear, and a line spacing mechanism for the platen including an operating lever tulcrumed coaxially with the platen and provided with a concentric cut-out portion forming spaced shoulders. and a gear rotatably mounted between the cut-out portion and the second gear and having driving engagement with said second gear, the rotary gear having a tooth projecting into the cut-out portion whereby upon movementof the operating lever in one direction the platen will be line spaced and the pressure rolls will be released.
