Definitions

  • the present invention relates to printing and more particularly to a type carrier device for a high speed printer apparatus.
  • High speed printers are known in which a horizontal type carrier transports a plurality of uniformly horizontally spaced displaceable type elements in a reciprocating movement along a print line.
  • the reciprocation may be incremental or it may be sweeping.
  • Printing occurs when hammer means located at various print positions along the path of travel strike individual select type elements causing them to be displaced transverse to the direction of motion of the carrier.
  • a resilient bias restores the displaced type elements after impact with a print medium to the normal aligned position.
  • One form of type carrier for a reciprocating printer comprises a flexible sheet metal comb. Characters are formed on the face of each of the fingers of the comb proximate the distal ends thereof. Each of the fingers of the comb is individually displaceable by hammers which strike the fingers causing them to bend out of the plane of the comb into contact with a print medium. Restoration of the bent fingers occurs through the inherent resiliency thereof.
  • a type carrier comprising a rigid, light-weight support member to which one or more flexible type elements of the spring leaf type are removably attachable.
  • Type element retaining means is provided which is also removably attachable to the type support member and which releasably engages the type elements.
  • the type support member is a thin-walled, rigid, hollow, cylindrical tube.
  • the print elements are comb-like members having one or more flexible finger portions extending from a common base portion and having characters formed proximate the distal ends thereof.
  • the base portion of each of the type elements includes an extension portion adapted to be mounted onto the tube support and to coact therewith and the retaining means to form a type carrier device.
  • the tube support is provided with passageways into which the extension portion of the type elements extend.
  • the retaining means preferably take the form of spring clips which are adapted to be spring attachable to the tube and which releasably engage the extension of the type elements within the passageways of the tube support.
  • passageways are formed in the tube support by two sets of openings through the wall of the tube support.
  • the first set of openings comprises a plurality of slits linearly aligned and uniformly spaced apart in an axial manner.
  • the second set of mounting openings comprises a plurality of uniformly spaced slits formed through the wall of the tube support in radial alignment with related slits of the first set.
  • each of the openings of the second set comprises enlarged access apertures at the ends of the slit portion to receive the spring clips.
  • the openings of the second set are, like the openings of the first set, separated by interopening wall portions between adjacent access apertures. 1
  • the spring clips are U- shaped springs having a pair of spaced resilient laterally deflectable spring fingers connected to a spring bridge member at one end thereof and having gripping means proximate the distal ends thereof.
  • the attachment of the spring clips is obtained by a snap-on action.
  • This preferably is provided by constructing the spring member with a pair of inwardly facing concave bends connecting the bridge member to the spring fingers.
  • the concave bends and bridge member portions of the U-shaped clips coact to grip the tube at the interopening wall portion thereof and at the same time, the concave bends provide a fulcrum for the spring fingers which is in contact with the external surface of the interopening wall portion in the second set of slits.
  • the extension is provided with hook means releasably engageable by said gripping means of the spring clip fingers.
  • the extension in a preferred form, is provided with hook means on both lateral edges.
  • the leading and trailing edges of the hook are both cammed to permit manual insertion and removal of the extension from the tube passages.
  • the trailing edge is cammed more abruptly so that a firmer retention of type element is provided and greater force is required to effect removal.
  • the hook means are laterally oppositely faced and engage spring fingers of separate adjacent spring clips.
  • the lateral edges of the type element extension deflect the spring fingers of the spring clips inwardly. Because of the concave bends in the spring fingers, they bend about an external fulcrum so that the spring clips grip the wall of the tube when the type element is being mounted on the tube as well as when it is being removed.
  • assembly of type elements can be achieved with ease and without use of special tools.
  • construction provides a light-weight, low mass type carrier having good alignment of type.
  • FIG. 1 is a perspective view schematically showing a printer apparatus in which a type carrier device of the present invention has utility.
  • FIG. 2 is an elevation view in schematic showing a hammer construction and drive mechanism useful in the printer apparatus of FIG. 1.
  • FIG. 3 is an isometric view in partially exploded form showing the type carrier of the present invention with portions in phantom.
  • FIG. 4 is a front elevation of the type carrier of FIG. 3 showing the sequence of assembling the type elements to the tubular type support member with portions of the tube shown in cross section.
  • FIGS. Sa-Sc show in sequence the coaction of the parts upon removal of the type elements from the type support member in the type carrier device of FIG. 3 with parts shown in cross section.
  • FIG. 6 is a front elevation view in partial cross section showing a second embodiment of the type carrier device of the present invention.

  • FIG. 1 shows .a printer apparatus which includes a platen 10, a print medium 11, and an ink ribbon 12 extending across the print medium 11 from supply and takeup reels 13 and 14.
  • the feeding of the paper 11 and ink ribbon 12 may be performed by suitable means in any well known manner and in particular may include electrical or mechanical means for advancing the paper a line at a time.
  • a plurality of uniformly spaced hammers 15 are arranged in a linear array along a print line, one hammer being located at each print position. While various forms of hammers may be used and various assemblies and operators employed to obtain operation of the hammers at the various print positions, the preferred print hammer mechanism takes the form described in US. patent application of Roland D. Nelson and Donald K. Rex, Serial No.
  • each hammer 15 comprises a body portion 16 having a slot 17 and all of the hammers 15 are pivotally mounted on a common stationary support rod 18.
  • the hammer mechanisms 15 further include a striking arm 19 extending outwardly from the central body portion 16 and a firing arm 20 extending below body portion 16 and to the rear thereof.
  • each hammer 15 in the preferred version of a hammer operator mechanism is provided with an individual holding magnet 21 having suitable energizing means, such as winding 22.
  • a return spring 23 is attached at one end to a stationary support 24 and has its free end in biasing contact with the body portion 16 at the edge surface above the pivot rod 18.
  • the hammer firing mechanism of the aforesaid application includes a cantilever leaf spring 25 for each hammer, each spring being mounted on a bail 26 which is pivotally suspended from a shaft 27 on one or more spaced apart arms 28.
  • Each spring drive 25 is made up of a number of leaves 29 through 32 of progresssively decreasing lengths.
  • Leaf 30 is provided with an angularly protruding finger 33 at its distal end.
  • the drive mechanism includes a spring reset assembly made up of a spring stop bail 34 pivotally mounted on shaft 27 by means of arm 35.
  • Each hammer firing mechanism is operated by a pair of cams 36 and 37 which are keyed in appropriate manner to rotatable shaft 38.
  • Cam follower 39 is carried by arms 28 in position to bear against cam 36 while cam follower 40 is carried by arm 35 in position to bear against cam 37. Cam followers 39 and 40 are kept in contact with their respective cams through the reaction of spring 41. While FIG. 2 shows a hammer firing mechanism for a single hammer 15, it is, of course, understood that the same firing mechanism would be supplied for each of the hammers 15 of the printer apparatus of FIG. 1.
  • the various shafts '27 and 38 may be mounted to a common support frame which supports the hammer mechanisms 15, the platen and the return spring 23 of the printer apparatus of FIG. 1.
  • a type carrier device Positioned between the print hammers 15 and the type ribbon 12 is a type carrier device comprising a plurality of spring leaf type elements 50 removably mounted on a horizontal reciprocating type element support tube 51.
  • Each of the type elements 50 includes a mounting extension portion 52 and a plurality of coplanar integral finger extensions 53 having type characters (not shown) formed on the distal ends thereof.
  • each type hearing finger 53 of type element 50 is provided with a different type character and each type element 50 has plural type characters forming a portion or segment of a type alphabet.
  • a complete type alphabet is provided for printing by assembling plural type elements 50, i.e., segments, in releasable manner on support tube 51 so that each type segment 50 is individually removable and replaceable in the assembly.
  • type elements 50 are moved horizontally past the array of hammers 15 and the various hammers are selectively operated to strike appropriate type characters at predetermined positions under control of means which might include memory devices or the like not shown.
  • the acceleration given to the hammer 15 causes it to continue in its clockwise movement until it strikes the type finger 53 and forces the type against the ink ribbon 12, the print medium 11, and the platen 10.
  • Hammer 15 then rebounds away from platen in a counterclockwise direction toward the holding magnet 21.
  • the hammer return spring 23 hearing against the upward extending flange of body portion 16 acts against finger 33 to hold the hammer after rebound in position slightly spaced from the edges of the magnets 21.
  • the horizontal motion of the type carrier which brings the various type fingers 53 into the various print positions may be provided by a rack and pinion gear arrangement which includes a pinion gear 54 connected in a suitable manner to any Well known reversible drive member (not shown) and a rack gear 55 which is attached to the underside proximate one end of tube 51.
  • a flag member 56 attached to the upper side of tube member 51 moves through a detector means 57 which through suitable control means connected to the pinion gear drive limits the stroke of tube 51 and reverses its direction.
  • Printing by operation of the hammers 15 to strike the type fingers 53 of type element 50 may be performed at rest or on-the-fly.
  • the type carriers 50 move into position so that each type finger is aligned with a different hammer 15 and stopped.
  • Hammer 15 is fired, then the type carrier moves the type elements 50 to the next horizontal position aligning each of the type fingers 53 at the next adjacent hammer position.
  • the process is repeated for the full length of the print line.
  • the tube member 51 is moved without intermediate interruption across the entire length of stroke parallel to the print medium 11.
  • the same bending action of the fingers 53 causes them to be displaced from the plane of the type elements 50.
  • the hammer means 15 enters the confines of the type element 50. It will be readily apparent that to accomplish the successive steplike movement or the continuous sweeping movement of the type elements 50 past the hammer mechanisms at high speeds that a failure on the part of the hammer mechanism 15 to be retracted might cause some difficulty which would tend to damage the print mechanism. In addition, it will be readily appreciated that extensive operation of the printer apparatus in the manner just described causes wear and other mechanical problems which may require the replacement of the type elements 50 from time to time.
  • each of the type elements or segments 50 is a spring leaf member having a base portion 52 from which a plurality of integral deflectable type fingers 53 extend in a common plane with each other and base portion 52.

  • Cuts 59 are formed in the corners of the edges of base portion 52 where horizontal shoulders 55 and 56 meet vertical shoulders 57 and 58 to simplify the manufacturing procedure by eliminating the need for making shoulders meet at a precise sharp corner. In addition, cuts 59 would afford some measure of stress relief.
