Definitions

  • a cartridge is provided for an endless flexible character bearing band, which is non-extendible, for use on a printer including two rotating pulleys through which [30] Forelgn Apphcanon Pnomy Data the above mentioned band slides, and with adjustable Oct. 1, 1971 France 7135482 center to center distance 52 US. Cl. 101/111, 74/212 1917/53
  • the eamidge includes a hmleihg which covers the /93 pulleys and is expendable and retractable, at least in a 51 Int.
  • the cartridge includes means for maintaining said band flat against a portion [56] References Cited of the inner walls of the housing, in relation to said pulleys when the outer edge of said portion is at most UNITED STATES PATENTS equal to the total length of saidband and freeing said garrgigton tape when the outer edge is greater than the total ma a 3,188,947 6/1965 Paige 101/93 c length Ofthe band 3,216,348 1l/1965 Oldenburg et al.
  • the present invention relates to a cartridge for a character-bearing band of a printing machine.
  • Printers with an endlessflexible band equipped with elastic tongues which are mounted along said tape and which carry the characters at their free end are a known device.
  • the strip is generally stretched over two rotating pulleys and forms an alongated loop consisting of two rectangular and parallel sections, along one of which the print hammers are arranged having anvils designed to cooperate with said characters which pass in front of them.
  • the distance from center to center of the axes of said pulleys is adjustable between a position in which the pulleys are closer to each other, which facilitates the mounting or removing of the slack band, and a position in which the pulleys are more distant one from the other which stretches the band and renders it ready for print.
  • the band and its characters run the risk of being damaged. This also applies during storing of such band outside the machine.
  • the mounting of the band is a relatively delicate operation.
  • the present invention corrects these shortcomings. For that purpose it is concerned with a removable cartridge which contains the band and makes possible the manipulation and the storing of the character-bearing band, without directly touching it.
  • the cartridge for a flexible, endless, inextensible character-bearing band of a printer comprising two rotating pulleys over which said band passes and whose distance from center to center of the axes is adjustable between a close position of the pulleys in which the band is slack and a more distant position in which the band is stretched and ready for print, is distinguished in that it comprises a casing which is designed to surround said pulleys and which is expansible and retractable at-least parallel to the direction of the relative.
  • the casing consists of two parts capable of sliding relative to each other parallel to the direction of the relative movement of the pulleys and made integral in translation, one with the axis of one of the pulleys and the other with the axis of the other pulley, for instance by insertion of the ends of said axes into corresponding recesses of said parts.
  • the device for moving the pulleys apart and bringing them together also controls the expansion and the retraction of the cartridge.
  • the character-carrying band is made of a material which is attracted by a magnet it is advantageous that the means designed to keep that band on the internal wall of the casing be magnetic.
  • the means may be a strip of magnetic material arranged partially on one part of the casing and partially on the other of said parts.
  • the character-bearing band is of a constant length it is detached from the strip of magnetic material, and is transferred to the pulleys. It is easy to see that a movement bringing the pulleys together provides for the return of the character-bearing band of the pulleys to the casing.
  • the cartridge furthermore protects it in storage.
  • the invention permits the transfer of the band from the casing to the pulleys, and from these to the casing without changing the level of the characters. It is even easier to provide reference stops on the band and the casing so that the former always occupies the same position in storage relative to its cartridge, a position which corresponds with the initial position of the band in the printer.
  • One of the parts of the casing is preferably fixed and completely su rrounds said pulleys, while the other part consists of a partition in the shape of a shell which is capable of sliding into-the interior of the first part.
  • the character-bearing band comprises to best advantage a rectangular section which may be placedopposite the print hammers and the corresponding anvil, and the casing includes a removable wall corresponding with that rectangular section and giving access to the characters.
  • the cartridge according to the invention may be equipped with a projecting grip handle carrying bolting means capable of interaction with other means born by the printer, when the handle is turned down.
  • This removable wall moreover, cannot be moved to free the access to the characters unless said handle is turned down.
  • the cartridge should preferably comprise encoding media for the band which it contains signaling to the printer the nature of said band.
  • the cartridge according to the invention makes possible the handling, mounting and setting in motion of the band with full reliability. Furthermore, it renders automatic the various operations of mounting, control, identification etc. of said band.
  • FIG. 1 is a longitudinal section in diagramatic form, taken perpendicular to the pulley axes, illustrating the cartridge according to the invention and in the position in which the parts are close to each other;
  • FIG. 2 is a longitudinal section in diagramatic form, taken perpendicular to the pulley axes, illustrating the cartridge according to the invention and in the position in which the parts are more distant one from the other;
  • FIG. 3 is a longitudinal section in diagramatic form
  • FIG. 6 is a cross section of the casing of FIG. in which the character-bearing band is still integral of the casing;
  • FIG. 7 is a cross section of the casing of FIG. 5 in the operating position.
  • FIG. 8 shows the device for keeping the parts of the cartridge in the storage position.
  • the cartridge shown in the FIGS. 1 to 4 is equipped with an oblong cover or casing 1, roughly in the shape of a trough, in whose interior a shell 2 may slide lengthwise, the shell being positioned close to one end of the cover, 1.
  • the shell 2. is fitted with a slide engaged in a slide bar installed in the cover 1 which renders said shell integral with the latter.
  • the slide and the slide bar are not shown in FIGS. 1 to 4 for purposes of clarity.
  • the shell 2 and the opposite end 3 of the cover 1 are of the same shape so as to conform to the shape of the drive pulleys 4 and 5 of the character-bearing band 6. These pulleys 4 and 5 are part of the printer (not shown).
  • the character bearing band 6 is of a conventional type and the construction thereof, exceptfor its magnetic attractive characteristics, is in no way a part of this invention.
  • Theipulley 4 is a drive pulley, while the pulley 5 functions as a stretching device. For this purpose, it is capable of sliding under the action of a screw 7, for instance, whereby the distance from center to center of the axes of the pulleys 4 and 5 is modified.
  • the base 8 of cover 1 has an opening 9 in which the free end of the shaft 11 of the pulley 4 may be inserted.
  • the diameter of the opening 9 corresponds with that of the end of shaft 11.
  • the end of the shaft 12 penetrates into an opening I3 provided in a bracket 14 which is solidly attached to the shell 2 and whose diameter is slightly longer than that of said end.
  • the shell 2 When the shell 2 is in its closest position to the end 3 the perimeter of the interior wall, bounded between the cover 1 and the shell 2, is equal to the total length of the character-bearing concave surface of the shell 2, oriented toward the end band 6. Consequently, the band is maintained flat against the portion of the inner wall of the cover 1 bounded by the end 3 and the shell 2 through the magnetic attraction between the band and the magnetic strips 15 and 16. As shown by FIG. 8, the shell 2 is kept in this close position when outside the machine due to a curved elastic blade 17 attached to the base 8 of the cover 1, and having its free end entered into the opening 13. g
  • the cover 1 includes a portion of a removable lateral wall 20.
  • FIG. 5 shows a preferred mode of design of a cartridge according to the invention.
  • the removable wall 20 is joined at 21 with a part 22 of the base 8 which in turn is connected with the latter at 23 so that it may be compietely turned down over said base 8 in the print position (see FIG. 7).
  • this type of design offers a carrying handle 24, jointed at 25 with the base 8.
  • This handle 24 is equipped with a hook 26 passing through said base 8 and is capable of interacting with the engagement means 27 in solid connection with the printer.
  • the shutters 20 and 22 cannot be turned down over the base 8 unless the handle 24 itself is turned down in that the handle normally lies in the path of the folding shutters. As a result one may only put the printer in the print position (see FIG. 7) when the cartridge cover 1 is clamped down by the intermediary of the hook 26 and the engagement means 27.
  • the cartridge may also include a protective arm 28 for the band which is operative only when the band is transferred to the pulleys.
  • the arm 28 not being a part of the claimed invention no description of the operative means thereof is made here.
  • the printer includes paper 29 and an ink ribbon 30 which are positioned between the hammers 31 and the band 6.
  • the cartridge In its section oriented toward the printer the cartridge carries a number of grooves 32 in which there may be inserted magnets 32a, while the machine is equipped with magnetic contactors 33 opposite said grooves. It is thus possible to assign a magnetic code to each cartridge and the associated character-bearing band and to transmit that code to the printer through conventional magnetic readout means which of themselves are not a part of this invention.
  • a reliable device has been designed which inhibits the opening of the wall section as long as the handle 24 is not turned down so that the hook 26 is engaged in the engagement means 27.
  • a cartridge for an endless character bearing band said cartridge being of a construction for normally storing a band in protected relation and for mounting the tape while still within the cartridge on spaced pulleys of a machine of the type having means for adjusting the spacing of the pulleys with the band assuming a config uration including a pair of runs joined by return portions, said cartridge comprising a casing having therein positioning means for reacting on the bandfor foreshortening the band and temporarily increasing the spacing between the runs thereof to facilitate the readily positioning of the band over the machine pulleys, said positioning means including a movable portion disposed adjacent one of the band return portions whereby when the cartridge is associated with the machine for the placing of the band thereon and the pulleys of the machine are moved apart, the band will be automatically grasped by the pulleys and completely drawn away from said positioning means.
  • said means for anchoring said positioning means movable portion relative to the machine other portion includes a bore for receiving a pulley component, said means for anchoring said positioning means movable portion in the band foreshortening position thereof includes a latch member interlockable within said bore, and in the positioning of said cartridge on the machine, said latch member is automatically displaced.
  • said magnet means is in the form of strip material secured partially to said casing and partially forming part of said positioning means movable portion, said positioning means movable portion further including a casing section movable relative to said casing.
  • a cartridge according to claim 8 wherein said handle prevents movement of said removable wall to a position permitting operation of the printer until the handle is turned to a cartridge clamping position.
  • a cartridge according to claim 1 characterized by means on the cartridge for coding of the band for signaling to the machine the nature of said band.
