Definitions

  • ABSTRACT A manual printer has a set of type wheels turned and set by manually operated rack bars which have additional slanted recesses and projections engaged by a spring-biassed arresting bar which is resiliently and yieldingly displaced by the slanted portions during setting of the type wheels.
  • the blocking lever is biassed by a strong spring to block the yielding movement of the arresting bar, but is held in an inoperative position by a feeler lever engaging a wheel of the platen carriage when the carriage is in the initial position so that the type wheels can be set with the arresting bar resiliently yielding.
  • the feeler lever releases the blocking lever which blocks the arresting bar in the position arresting the rack bars and thereby the type wheels, so that the manual force during setting, and the action of the platen during printing, cannot displace a type wheel set in the initial position of the carriage.
  • Another object of the invention is to block the yielding arresting means when the carriage and platen move out of the initial position during a printing stroke.
  • a preferred arrangement of the present invention comprises a set of type wheels mounted on supporting means for angular movement.
  • setting means including rack bars having a series of gear teeth meshing with arresting gears secured to the type wheels so that an aligned row of types represents information.
  • the rack bars also having a series of slanted recesses and projections correlated with the types
  • carriage means including a platen being mounted for movement in a printing stroke out of an initial position and to a printing position in which the platen roller moves over the aligned row of said types
  • yieldable arresting means including an arresting member extending across the rack bars and arresting spring means biasing the arresting member to engage selected recesses, and to resiliently yield when engaged by one of the projections during setting of the type wheels
  • blocking means having a blocking position engaging and blocking the arresting means in the arresting position so that the type wheels are blocked, and an inoperative position spaced from the arresting means, biassing means for urging the blocking means to the blocking position, and linkage means connecting the carriage means with the blocking means so that in the initial position of the carriage means, the blocking means is held by the carriage means and linkage means in the inoperative position against the action of the biassing means.
  • the type wheel means can be set with the arresting means resiliently yielding, but during the printing stroke of the carriage means, the blocking means is released for being held by the biasing means in the blocking position so that the type wheels are blocked against displacement by the platen roller or by the setting means.
  • FIG. I is a perspective view illustrating a printer according to the invention on a reduced scale
  • FIG. 2 is a fragmentary elevation, partially in section, illustrating the arresting and blocking device according to a preferred embodiment of the invention
  • FIG. 3 is a perspective bottom view of the embodiment of FIG. 2;
  • FIG. 4 is a fragmentary perspective top view of the embodiment of the invention shown in FIG. 1.
  • a manual printer has a housing 4 on which a machine bed I is mounted, forming longitudinal slots between housing walls and machine bed 1.
  • a carriage 2 is movable out of the illustrated initial position along the printing bed in a printing stroke, and then returned to the initial position.
  • the platen moves over a copy sheet P shown in broken lines, whose position is determined by corner abutments of which only one abutment 1a is shown.
  • a credit card C can be placed, so that during the printing stroke, information is transferred from the credit card to the copy sheet.
  • a set of coaxial type wheels 5, generally indicated A projects partly from the interior of housing 4 through a cutout in the machine bed I, so that a row of numerals is also imprinted on the copy sheet.
  • These data are variable and are set by manual operation of buttons or keys 7a which are mounted on setting portions 7b, as shown in FIGS. 2 and 3.
  • a cover 4a is provided with slots 4b for the setting portions 7b, and with windows 41' in which numerals corresponding to the numbers set on the type wheels 5 appear.
  • the bed plate I is shown to have a cutout for the type wheels 5 each of which is integral with, or fixedly secured to a gear 6. All type wheel means 5, 6 are mounted on a common shaft 4 for free rotation, and each type wheel 5 has a series of types 50 around its periphery.
  • the carriage 2 has legs 2a projecting downward under the bed plate 1, and carrying wheels or rollers l8, l9 rolling on the top and bottom surfaces of the bed plate I.
  • FIG. 3 only a single roller 18 is shown which cooperates with a feeler lever 56 mounted on the bed plate 1 for pivotal movement with the pivot 58.
  • Feeler lever 56 is biassed by a strong spring 59, and the arrangement is such that in the initial position of the carriage 2, the wheel 18 engages the curved free end of feeler lever 56 and displaces the same against the action of the strong spring 59.
  • the wheel 18 releases feeler lever 56 so that spring 59 becomes effective to turn the feeler lever in the direction opposite to the arrow H for a purpose which will be explained hereinafter.
  • the rack bars 7 are integral with the setting portion 7b, and are guided for horizontal setting movement by slots 14' and 15 on transverse guide shafts l4 and 15.
  • Each rack bar 7 has a series of rack teeth 7', meshing with the gears 6, so that different types 5a are placed in the operative position 5b in accordance with the longitudinal displacement of the rack bars 7 by the manually operated portions 7a and 7b.
  • rack bars 7 While the upper edges of rack bars 7 have the rack teeth 7, the lower edges of rack bars 7 have slanted arresting projections 8a and arresting recesses 8.
  • An arresting bar 22 of angular shape is mounted on lever means 20 which are mounted on a shaft 21 on the frame of the housing, and are biassed by an arresting spring 24 connected with the arm 20a.
  • the force of spring 24 urges the arresting bar 22 into transverse row of slanted arresting recesses 8a so that all rack bars 7 are resiliently engaged and arrested.
  • the force of spring 24 is selected so that a displacement of the setting rack bars 7 causes the respective slanted projection 8a to urge the arresting bar 22 out of the engaged recesses 8 so that setting of the type wheel to a selected angular position is possible for each type wheel.
  • a double armed blocking frame is mounted on a vertical shaft 51 secured to bed plate 1, and has a blocking portion 50a cooperating with the portion a of the arresting lever means 20, as best seen in FIG. 2.
  • the upper arm 50b of the frame 50 is secured to the end of the linking rod 54 Whose other end is connected with the feeler lever 56, as described above.
  • feeler lever 56 is turned by carriage wheel 18 or by spring 59, the link rod 54 is displaced, and blocking frame 50 turns with blocking member 50a.
  • buttons 7a are manually operated to set the rack bars 7 to selected posi tions in which the top row formed by the aligned types 5b, is in the printing position under the copy sheet P, as best seen in FIG. 2.
  • the carriage 2 with the platen 3 is in an initial position, shown in FIG. 1, in which the wheel 18 engages the end of feeler lever 56, and holds the same against the action of the biassing spring 59 in a position in which the frame 50 is turned about shaft 51 to a position in which the blocking portion 50a is spaced from the lever portion 20a, so that the arresting means 20, 22 can freely move under the control of the slanted projections 811, as is required during setting of the type wheels 5.
  • the carriage 2 When the setting has been completed, the carriage 2 is manually moved out of its initial position so that the wheel 18 moves with the respective projection 2a, and releases the end of the feeler lever 56 so that the feeler lever 56 is turned by the strong biassing spring 59 in clockwise direction as viewed in HS. 3, whereby the link 54 turns the blocking frame 50 with the blocking member 50a to an inoperative position spaced from the lever portion 200 of the arresting means 20, 22.
  • the blocking pressure by the blocking portion 50a is derived from the strong biassing spring 59 whose spring force is much greater than the force of spring 24.
  • the arresting means 20a, 20, 22 are turned by the stronger force of biassing spring 59 to a position in which the angular arresting bar 22 holds all rack bars 7 blocked and immovable so that the rack teeth 7' block the gears 6 and thereby the type wheels 5 in the selected angular positions.
  • the carriage 2 with the platen 3 can now move in the printing stroke so that the platen roller 3 moves over the copy sheet P, over credit card C, and over the top row of set types 5b so that an imprint of the credit card data and of the selected number are made on the copy sheet.
  • the carriage 2 is now moved to its other end position, and then in a return stroke toward the initial position.
  • the wheel 18 approaches the curved end portion of feeler lever 56, the latter is turned in the direction of the arrow H, as shown in FIG. 3, whereby the biassing spring 59 is tensioned.
  • the wheel 18 locks the feeler lever 56, so that the blocking means 50, 50a are moved to an inoperative position in which the blocking portion 50a releases portion 20a of the arresting means 20, 22 so that the weaker arresting spring 24 becomes again effective, permitting displacement of the arresting lever 20 against the action of spring 24 when the arresting bar 22 is subjected to the pressure of the slanted face of a projection 8a during longitudinal displacement of any selected rack bar 7.
