Abstract: 477,947. Typewriters &c. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 15, 1937, No. 16610. Convention date, July 25, 1936. [Class 100 (iv)] Type-bar machines.-In machine comprising slidable type-bars arranged in groups in a frame, the type-bars are set differentially by means of a sliding template. The machine shown in Figs. 2 and 5 prints an identification number and a price on each of a series of tear-off coupons forming part of a ticket employed in keeping a record of the time spent by a number of workmen in the manufacture of an article. The machine comprises a number of groups of pairs of type-bars 22, 23 for printing on the coupons a price and identification number respectively, and type-bars 24, 25 for printing code information at the top of the ticket. The type-bars are arranged between guide-plates 19 and rest on washers 20. The type-bars 22, 24, 25 are formed with notches for holding types 30, and the type-bars 23 are formed with types. A series of types is mounted in the front part of each type-bar 22 of a pair and in the rear part of the other type-bar of the pair, the arrangement enabling the pair to print simultaneously on two coupons at opposite edges of the ticket. If the same identification number is to be printed on opposite coupons, both type-bars 23 of a pair are provided on the front and rear parts with numeral types, but if the numbers differ, the numeral types are provided on the front part of one type-bar and the rear part of the other. The type-bars 22 in all the groups are set differentially by means of a template 31 having tongues 33 for engaging the front ends of the type-bars. The template is placed in a carriage 34 comprising front and rear bars 35, 36, and sides 37 having flanges 38, 39 for engaging the template. The carriage is supported by rails 38a and is operated. by means of a crank 48 on a rockshaft 45 having sectors 44 gearing with racks 43 on the carriage. The type-bars 23 in all the groups may be set differentially by means of tongues on the template 31, but preferably a separate template 50, mounted in an extension 54 of the carriage 34, is employed for this purpose. The template 50 may consist of a plate formed with punched lugs 52 for engaging extensions 53 of the type-bars 23. Graduations 51 on the plate indicate the positions at which the plate should be punched. The type-bar 24 is set by means of one of the tongues 33 on the template 31, and the typebars 25 are set by means of knobs 63 in connection through shafts 62 with pinions 61 gearing with racks on the type-bars. The setting of the type-bars 25 is indicated by means of racks 64 which gear with pinions 69 on the shafts 62 and have index-characters on the top. When the crank 48 is moved rearwards, the type-bars 22, 23, 24 are set by means of the templates, the selected types being arranged in two lines for printing on sets of coupons at opposite sides of a ticket placed on a table 17. Printing may be performed in two stages, the type-bars being set successively by the templates 31, 50. Impression is effected by rollers 78, described below, and the types are inked by a ribbon 73. The template may carry a type-block 58 for printing instructions on the ticket, impression from the type-block being effected by depressing a knob 91 which engages linkage 92, 93 carrying an impression block 90. After impression, the crank 48 is returned, and the rear bar 36 of the carriage 34 restores the type-bars. Aligning for impression.-The type-bars 22 .. 25 have fingers 40 engaging notches 41 in a plate 42, or alternatively are formed with teeth engaging V-bars on the guideplates 19. Roller-impression arrangements.-Two impression-rollers 78 are mounted in a frame 79 guided vertically in a slide 80 which engages guide-grooves 82 in a housing 75. Springs hold the frame 79 in raised position. A knob 84 has pin-and-slot engagement with a cam pivoted on the slide 80 and abutting on the frame 79. The knob is moved laterally, to rock the cam and thereby depress the impressionrollers on to the ticket, and is then moved along a slot 85 to traverse the impression - rollers along the ticket.
