Definitions

  • FIG. 4 TYPE-WRITER RIBBON CARTRIDGE Filed March 9, 1967 FIG. 4
  • a cartridge for an inked printing ribbon or similar thin web material is provided.
  • the cartridge comprises a pair of spools which alternately serve as supply and take-up spools as the inked ribbon or similar web material is fed back and forth.
  • a resilient bistable member Disposed between the pair of spools is a resilient bistable member which, in the preferred form of the invention, is a bowed leaf spring held at both of its ends.
  • the bowed portion of the leaf spring engages the outer convolutions of the ribbon or similar web material being wound on the spool serving as the take-up spool to insure the ribbon is tightly and properly wound on this spool.
  • the diameter of the ribbon on the take-up spool increases to such an extent that the leaf spring flips to its other stable state where the bowed portion thereof is disposed toward the supply spool.
  • the leaf spring is, therefore, positioned to cooperate with the ribbon or similar web material which will be wound on the supply spool when the direction of feed for the ribbon or similar web material is reversed.
  • the present invention is directed to the container and printing arts. More particularly, it is concerned with the provision of a highly simplified cartridge for receiving an inked printing ribbon or other similar thin web material.
  • Printing of a higher quality compared to that provided when using an inked fabric ribbon can be obtained by employing a matrix type plastic ribbon.
  • a plastic ribbon is disclosed in copending application Ser. No. 536,557 entitled Transfer Medium and Method for Making Same, filed Mar. 9, 1966, in the names of H. T. Findlay and K. H. Froman and which is assigned to the assignee of the present invention.
  • This ribbon comprises 3,3553% Patented Dec. 5, 1967 a plastic substrate or matrix having many small voids which entrap and hold small pockets of ink. The ink is partially forced from these pockets on each typing operation.
  • a number of high quality printed characters or images are obtained from typing repetitively on the same area of the plastic ribbon, and the ribbon is reusable. This permits the ribbon to be employed in much the same manner as a fabric ribbon in that it can be fed back and forth between a pair of spools past the printing point by the reversing ribbon feed mechanism.
  • plastic ribbon has seriously limited the ability to package plastic ribbon in fabric ribbon cartridges prior to this invention. While the plastic ribbon is reusable, it is not reusable as many times as an inked fabric ribbon. Because there is an uneven dispersion of ink in the plastic ribbon with more ink disposed toward the document being printed, the ribbon is relatively thin and, in fact, is self-supporting in its preferred form. This thinness of the ribbon permits a greater quantity or length of ribbon to be wound on the spools in a fabric ribbon cartridge. However, the thinness of the ribbon which nominally permits an acceptable length of ribbon to be wound in a fabric ribbon cartridge presents other problems.
  • the plastic ribbon is so thin that it is deformed under impact of the type and, because of this deformation, is Wound in a loose manner on the take-up spool with each turn or convolution occupying a much greater radial distance than would normally be expected considering the initial thickness dimension of the ribbon.
  • Increasing the tension on the ribbon being wound on the take-up spool reduces this problem, but is not completely acceptable since too much tension causes the ribbon to be stretched longitudinally and/or to fold over on itself about the deformed center portion thereof. Also, this requires an undesirable modification to the reversing ribbon feed mechanism of the typewriter.
  • the result has been that prior to the present invention it has not been possible to obtain a fully suitable or satisfactory number of printing impressions from a plastic ribbon mounted in a fabric ribbon cartridge. Only a limited length of plastic ribbon can be employed and the typist is required to change the cartridge at too frequent intervals to provide a really practical or economically attractive ribbon cartridge assembly.
  • a further object of the invention is the provision of a ribbon cartridge having a bistable pressure applying resilient member which automatically switches its states into alternate operative relation with the spools of the cartridge.
  • the resilient member comprises a bowed leaf 9 a spring disposed between the spools in the cartridge. The ends of the leaf spring are held and the leaf spring switches its state in response to the growth of the diameter of the ribbon wound on the spool serving as the take-up spool at that time.
  • a still further object of this invention is to provide a cartridge for a ribbon having the characteristics set forth above which is readily manufactured at low cost. In this manner, the entire cartridge assembly can be discarded after the ribbon has been used.
  • FIGURE 1 is a fragmentary top plan view showing a typewriter ribbon cartridge constructed in accordance with the teachings of the present invention
  • FIGURE 2 is a front sectional view taken along the section line 22 of FIGURE 1;
  • FIGURE 3 is a side sectional view taken along the section line 3-3 of FIGURE 1 of one of the ribbon spools indicating the manner in which the spools cooperate with the spindle assemblies of the reversing ribbon feed mechanism;
  • FIGURE 4 is a side sectional view of one of the ribbon spools indicating the manner in which the spools cooperate with the spindle assemblies of the reversing ribbon feed mechanism;
  • FIGURE 5 is a side view of the bistable leaf spring employed in the ribbon cartridge of this invention.
  • FIGURE 6 is a fragmentary top plan view similar to FIGURE 1 showing the leaf spring in its other stable state.
  • the ribbon cartridge comprises a housing It? and a pair of spools 11 and 12 which may be made from any suitable material, such as heat formable plastic.
  • the cartridge housing includes a top wall 13, a depending side wall 14 formed integrally with the top wall and a cover plate 15 defining a bottom wall.
  • Each of the spools 11 and 12 comprises an annular hub 18 and a pair of vertically spaced circular flanges 19 and 20.
  • the hub 18 has an axial opening 21 extending theretlu'ough which has locating and driving elements 22 positioned on its surface.
  • the axial opening 21 in each hub 18 is adapted to nestingly receive a spindle assembly 23 of the reversing ribbon feed mechanism mounted on the typewriter.
  • the spindle assembly 23 comprises a pivoted reversing lever 24, which, when the ribbon is almost exhausted from the spool serving as the supply spool, is allowed to pivot outwardly under the action of spring 25.
  • the movement of the pivoted reversing lever 24 actuates the reversing portion of the ribbon feed mechanism so that the direction of ribbon feed is reversed and the ribbon is now wound on the spool which previously served as the supply spool.
  • the ribbon feed mechanism itself will not be described further in this specification, but those desiring additional information concerning the same should refer to the above mentioned patents and instructional manual.
  • the spools 11 and 12 are accurately located and mounted for rotation within the cartridge housing.
  • the top wall 13 of the housing has a pair of apertures 26 therein which receive the projecting upper ends of the annular hubs 18.
  • the inner or bottom surface of the top wall 13 has a pair of circular recesses 27 therein which are the same general size as and nestingly receive the top flanges 19 of the spools.
  • the bottom cover plate 15 has a circular cutout portion 28 that permits the large projecting lower ends 29 of the hubs 18 to extend therethrough and circular recesses 30 that nestingly receive the bottom flanges 21) of the spools.
  • the arrangement is such that the spools 11 and 12 are accurately located and held within the cartridge housing, but yet these spools are easily rotated so that a minimum of tension is applied to the thin and relatively fragile plastic ribbon 35.
  • the plastic ribbon 35 has its opposite ends attached by adhesive or any other convenient attachment means to the outer surfaces of the hubs 18 of spools 11 and 12.
  • the ribbon is wound on the spools and extends from one spool to the other through a pair of slots 36 formed in the side wall 14 of the cartridge.
  • the portion of the ribbon which extends outside the cartridge housing is adapted to be received in typewriter ribbon guides, not shown. In this manner, the ribbon is located adjacent the printing point and raised to a position to be struck by the print element during a printing operation.
  • the side wall 14 of the cartridge is also formed with integral 1oeating and mounting recesses 37 for receiving spring biased holding elements, also not shown, of the reversing ribbon feed mechanism so that the cartridge is accurately located and securely mounted on the typewriter.
  • the side wall 14 of the cartridge has a pair of vertically extending mounting posts 38 and 39. These mounting posts are formed integrally with the side wall 14 of the cartridge and are disposed on opposite sides thereof. A line interconnecting these mounting posts bisects and extends transversely to a line connecting the center axes of the spools 11 and 12. Each of the mounting posts 38 and 39 has an end portion 40 which projects through and below an aperture in the bottom cover plate 15.
  • FIGURE 5 of the drawings When the ends of the leaf spring are received in the slots 42 of the mounting posts, the leaf spring assumes one of the two bowed positions or states shown in FIGURES 1 and 6 of the drawings.
  • the leaf spring 44 has a width dimension which is slightly less than the width of the plastic ribbon while the tabs on the T-shaped ends 43 locate the spring so that the same is freely movable between the flanges 19 and 20 of the spools 11 and 12.
  • the plastic ribbon 35 continues to be wound on the take-up spool 11 and as the mass of ribbon on this spool grows in diameter, the center portion of the bowed leaf spring 44 is deflected.
  • the ribbon on the take-up spool 11 reaches a size that the leaf spring is flipped or switched to its other stable position with the bowed portion extending toward the supply spool 12. This occurs slightly before the ribbon is completely exhausted from the supply spool 12 and prior to or at the time of actuation of the reversing apparatus of the ribbon feed mechanism.
  • the preferred design of the apparatus is such that the leaf spring does not engage the ribbon or the spools during and immediately after ribbon reversing operations.
  • the ribbon begins to wind on the spool 12 which now serves as the take-up spool.
  • the mass of ribbon on this spool quickly grows in diameter until it is engaged by the bowed center portion of the leaf spring 44 and typing operations continue as outlined above.
  • the take-up spool 12 is nearly full, the leaf spring 44 is flipped or switched to its other stable state prior to the actuation of the reversing apparatus. This series of operations continues in an uninterrupted manner until the ribbon has been used to the desired extent. Then the typist removes and discards the cartridge containing the used plastic ribbon and replaces it with a new cartridge.
  • the end portions 40 of the mounting posts 38 and 39 which extend through the apertures in the cover plate 15 assist in maintaining the parts of the cartridge in assembled relation.
  • the end portions 40 are preferably hot upset or otherwise deformed so that the cover plate 15 is maintained in assembled relation with the other parts of the cartridge.
  • the hot upsetting of the ends of the mounting posts 38 and 39 also seals the ends of the slots 42 and prevents the removal of the bowed leaf spring 44. While a preferred construction of the ribbon cartridge has been disclosed, it should be readily apparent that the same may be fabricated from a greater or smaller number of individual parts and any of a wide variety of attachment procedures and means can be employed to join or secure these parts together.
  • the leaf spring 44 was a strip of spring steel having a thickness dimension of .002 of an inch and a length dimension of approximately 1 inches.
  • the linear or straight line distance between the mounting posts 38 and 39 of the cartridge was about 1 inches.
  • the use of the leaf spring in this instance permitted approximately 20 yards of plastic ribbon having a thickness of about .0023 of an inch to be wound on the spools and fed back and forth past the printing point without any difiiculty. When the leaf spring was removed, it was possible to wind only about 15 yards of plastic ribbon on the spools if the ribbon was to be fed back and forth without jamming.
  • An inked ribbon cartridge comprising:
  • said leaf spring extending between opposite portions of said side wall
  • said leaf spring having a length greater than the straight line distance between said opposite portions of said side wall to provide said leaf spring with a bowed center portion;
  • said bowed center portion of said leaf spring having two operating positions
  • said bowed center portion of said leaf spring in one of said two operating positions extending toward and engaging the mass of ribbon being wound on the one of said spools serving as a take-up spool;
  • said mass of ribbon on said one of said spools switching said bowed center portion of said leaf spring to the other of said two operating positions adjacent the other of said spools when at least half of said ribbon is wound on said one of said spools.
  • Apparatus according to claim 1 further comprising:
  • Apparatus according to claim 2 further characterized by:
  • said leaf spring having T-shaped end portions to accurately position and locate said bowed center portion between said upper and lower supporting walls of said casing.
  • Apparatus according to claim 2 further characterized by:

  • said end portions of said mounting posts being deformed to block said aperture and maintain said bottom cover plate in assembled relation with said side wall.
  • An inked ribbon cartridge comprising:
  • a casing having upper and lower walls extending parallel to each other;
  • a pair of spools arranged in said chamber and being supported for rotation on spaced parallel axes;
  • a resilient leaf spring having a bowed center portion positioned between said spools
  • said bowed center portion of said leaf spring having two operating positions
  • said bowed center portion of said leaf spring in one of said two operating positions extending toward and engaging the mass of ribbon being wound on the one of said spools serving as a take-up spool;
  • said mass of ribbon on said one of said spools switching said bowed center portion of said leaf spring to the other of said two operating positions adjacent the other of said spools when at least half of said ribbon is wound on said one of said spools.
  • a ribbon cartridge for thin web material comprising:
  • a casing having upper and lower walls extending parallel to each other;
  • a pair of spools arranged in said chamber and being supported for rotation on spaced parallel axes;
