Definitions
- a carbon ribbon assembly comprising a supply reel on which a carbon ribbon is wound and a takeup reel to which a lead end portion of the carbon ribbon is wound. Each reel is placed and locked within a two part housing having in its periphery a ribbon passage so that carbon ribbon can pass from the supply reel to the takeup reel.
- the housings have pin and hole associations by which they are adapted to be secured axially superimposed on each other against relative rotation for shipping and storage purposes but are easily separable for their association by the pins of their pin and hole associations
- CARBON runnon ASSEMBLY BACKGROUND Carbon ribbon reels are generally located flatwise on the side frames of a machine with the cores on the supply and takeup reels rotating on horizontal axes. A new carbon ribbon usually comes to the user on a supply reel for installation on the machine. For example, in the Urso et a1.
- a carbon supply reel is part of a package and after separation from such package it must be threaded between guide rollers, guides, a vibrator, takeup and tensioning drives, and must be attached and wound on a takeup reel. This requires excessive handling of the spools and the ribbon so that the handler is apt to soil the hands and also is apt to incorrectly thread the ribbon.
- a US. Pat. to Lambert, No. 2,825,545 discloses a package containing two ink ribbon spools in containers which are joined in a flat plane but are adapted to be fractured from each other to facilitate installation of a ribbon in a facile manner.
- carbon ribbon is wound on a supply reel contained in a housing therefor and a leader strip extends therefrom to a reel on a takeup reel which is contained in another housing.
- the housings containing the supply reel and the takeup reel are identical and consist preferably of two composite molded parts which by means of spring fingers are adapted to be snapped together with their respective reels introduced therebetween.
- the housing bottoms are each oppositely provided with a plurality of axially extending protuberances and openings in a manner so that the housings can grippingly be locked together axially and against relative rotation during shipping and storage.
- An object of the invention therefore is in the provision of a doublereel carbon ribbonpackaging and functional assembly which facilitates storage, use and disposal of carbon ribbons, and particularly provides that the operator's can stay free of carbon matter.
- FIG 1 is a sectional view showing a double housing containing a carbon ribbon supply reel and a takeup reel;
- FIG. 2 is a plan view showing the housings containing the supply and takeup reels separated for mounting;
- FIG. 3 is a front sectional view of the housed takeup reel positioned to be lowered into position on machine mountings;
- FIG. 4 is an enlarged fragmentary sectional view of a housing detail
- FIG. 5 shows in enlarged aspect housing details for clipping two component housing parts together
- FIG. 6 is a plan view showing the reel housings and carbon ribbon installed in a machine.
- FIG. 1 a carbon ribbon marketing unit 10 comprising a housing 11 containing a carbon ribbon supply reel 12 and an identical other housing 13 superimposed thereon in a separably attached manner and containing a ribbon takeup reel 14.
- the ribbon supply reel 12 comprises a hub 15 and a single flange 16 thereon.
- the ribbon takeup reel 14 comprises a hub 17 and two spaced flanges l8 wherebetween a carbon ribbon 20 is adapted to be wound, carboncoated side facing inwardly on the hub 17.
- the two housings ll, 13 consist each of two complemental parts 21, 22.
- Each of the complemental housing parts 21 comprises a flat ring portion or disk 23 having a central opening [9.
- Disk 23 has an integral peripheral wall 24 projecting therefrom and each of the complemental parts 22 similarly comprises a flat ring portion or disk 25 having a central opening 19.
- Disk 25 has a peripheral wall 26 projecting therefrom.
- the peripheral walls 24, 26 of the complemental parts 21, 22 are of matching diameter, face toward each other from the ring portions 23, 25 and abut each other at various points, as will be made clear later herein.
- the reels 12 and 14 as well as the complemental parts 21 and 22 are molded of lucite.
- each housing l1, 13 has at each of three circumferentially equally spaced locations a spring finger 27 which reaches across the peripheral wall 24 of the housing part 21.
- Each such finger 27, see FIG. 4 has at its extending end a catch lug 28 to spring into a local relief or hole 30 of the peripheral wall 24 of the component part 21.
- the spring fingers 27 are thus instrumental to hole the complemental housing parts 21 22 together.
- the catch lugs 28 are bevelled at 31 so the complemental housing parts 21, 22 can be readily assembled by pushing them together in axial alignment with their respective reels 12, 14 introduced therebetween.
- the complemental parts 21, 22 may be separated conveniently by flexing the fingers 27 outwardly, thereby allowing repair.
- the peripheral wall 26 of each of the housing parts 22 has at each of the three spaced peripheral locations of the spring fingers 27 a gap 32, see FIG. 5. Into each such gap 32 reaches a tongue extension 33 of the peripheral wall 24 of the related complemental housing part 21. These tongue extensions 33, in cooperation with the gaps 32, facilitate the association of the housing parts 21, 22 in appropriate relations upon each other for assembly.
- the peripheral walls 24, 26 of the complemental housings 21, 22 abut each other locally at 34 adjoining said tongues 33 but otherwise are preferably slightly separated as shown.
- peripheral walls 24, 26 of the supply and the takeup reel housings 21, 22 respectively have local interruptions bordered by ribbon guide fingers 36, see FIG. 2, which are carried by the peripheral wall 26 of the housing part 22 and reach across the peripheral wall 24 of the component housing part 21. Said fingers 36 afford uninterrupted, smooth ribbon guiding edges defining ribbon passages.
- the supply reel housing 11 and the takeup reel housing 13 are shown in their upright positions in which they are to be placed onto the machine. Namely, the flat ring portions 25 of the housings 11 and 13 are on top.
- the carbon ribbon 20 wound on the supply reel 12 in the supply reel housing 1! ends in a leader strip 37 of suitable length which is devoid of carbon coating and extends through the passage defined by the guide fingers 36 on the housing 1 1. From there the leader strip 37 extends to the takeup reel housing 13 to enter thereinto through the passage defined by the guide fingers 36 thereon.
- the leader strip 37 is attached to the hub 17 of the takeup reel 14 by a piece of adhesive tape indicated at 38.
- the supply reel housing 11 is shown in a position inverted to the normal position in which it is to be used in the machine, but the takeup reel housing 13 is in its normal upright position in which it is used in the machine. Moreover, the leader strip strip 37 extends from the supply reel housing 11 on a bias into the takeup reel housing 13 over one of the guide fingers 36 thereon.
- the takeup reel housing 13 is separably attached upon the supply reel housing 11.
- the flat ring portion 23 of the takeup reel housing 13 has two diametrically opposite protuberances or pins 41 which are engaged in or match holes 42 in the flat ring portion 23 of the supply reel housing 11.
- the latter has two protuberances or pins 43 which circularly on its ring portions 23 are midways between the holes 42 therein and are engaged in or match holes 44 in the flat ring portion 23 of the takeup reels housing 13.
- the fit of the protuberances 41, 43 in the holes 42, 44 is preferably such that the housings ll, 13 cling together.
- both housings 11 and 13 are identical in all respects.
- the ribbon passages defined by the guide fingers 36 are 90 circularly offset in respect to each other, thereby to provide that the leader strip 37 will extend between passages provided by the fingers 36 at a reasonable bias.
- the marketing unit shown in FIG. 1 When the ribbon 20 is to be used in the machine the marketing unit shown in FIG. 1 may be removed from a box and the corrugated board 40 is taken hold of midway between its ends and removed. Then the takeup housing 13 may be grasped and held by the left hand in the position shown in FIG. 1 and supply housing 11 grasped and held by the right hand and folded 180 degrees away from under the housing 13 into a rightwardly adjacent relation to the takeup housing as shown in FIG. 2.
- FIG. 6 the ribbon supply housing 11, as well as the ribbon takeup housing 13, are shown installed in a typewriter respectively on a frictionbraked shaft 45 and a winding shaft 46.
- the leader strip 37 extends over a roll 47 reversely toward and through a conventional ribbon vibrator 48 and from there to between two ribbon feed rolls 50, 51 and over a guide stud 52 into the ribbon takeup housing 13 onto the reel 14 therein.
- the winding shaft 46 protrudes upwardly through a frame member 53 which carries the guide stud 52 and the feed roll 50, and indirectly also the feed roll 51.
- This frame member 53 supports a platform 54 which has holes 55 therein so that the ribbon housing 13 by the protuberances 41 on its flat ring 23 can be located in concentric relation to the shaft 46 and with the ribbon passage defined by the fingers 36, appropriately located in respect to the guiding pin 52 on the machine.
- a similar platform 54, not shown, is present in reference to the frictionbraked shaft 45 and has also holes 55, such holes 55 to receive the supply reel housing 11 by its protuberances 43, concentrically correlated to the shaft 45.
- the housings ll, 13, for removal from the package may first be maneuvered to lower the ribbon leader strip 37 into the vibrator 48 and into proper association with the guides 47, 52 and the rolls 50, 51. Then the housings 11, 13 may be dropped into appropriate positions on the platforms 54. During this entire installing process no portion of the carbon ribbon 20 is exterior of the housings 11, 13, so that the operator's hands remain completely clean. When the ribbon 20 needs to be replaced, the housings 21, 22 are grasped to remove them and the ribbon 20 from the machine for disposal.
- a carbon ribbon package assembly for use in a typewriter, comprising in combination:
- each of said housings comprising a pair of flat disks provided with rim means directed toward one another to provide spacing wherebetween its respective reel is accommodated
- said housings being each adapted for association upon the typewriter by a particular one of its disks and such disk having a central opening for facilitating such association
- a carbon ribbon package assembly for use on a typewriter comprising in combination,
- each twopart housing comprising two disks having each a projecting peripheral rim facing toward one another providing a space therebetween, said reels being each accommodated between the disks of their twopart housings with room for freely rotating therein,
- At least one of said disks of each housing having a central opening to facilitate the association of the reel in the housing by its hub with a machine part
- each twopart housing includes a plurality of detent prongs extending from at least one housing part to resiliently snap onto the other housing part.
