362,463. Typewriters &c. WARD, E. J., 4, Park Place, Knightsbridge, London. June 6, 1930, No. 17641. [Class 100 (iv).] Type-wheel machines ; roller-impression arrangements.-Relates to machines for simultaneouslv printing an amount in words and numerals, and comprises a travelling impression member, means for print zeros to the right of the last significant numeral, and means for repeat printing. The machine shown in Figs. 1 and 2 comprises two groups of type-wheels for printing words and numerals mounted on shafts 3, 31, respectively, impression rollers 165, 166 for the two groups being mounted on a slide 164 supported by a rod 163. The impression rollers pass through slots in a plate 160, the paper and an ink ribbon being arranged between the type-wheels and impression rollers. The slide is connected to a band 176 passing over pin rollers 174, the shaft 178 of one of the rollers being geared to an operating crank 126. The impression rollers are preferably effective in one direction of .traverse only. For this purpose, the shafts 167 of the impression rollers are arranged in slots in the slide 164, and each shaft engages rods 170 mounted in the slide and forming part of a U- member. When the slide has been traversed to the right, abutments displace the rods, and springs press the shafts into recesses in the rods, thereby rendering effective the impression rollers during traverse to the left. When the slide has been traversed to the left, abutments return the rods and the impression rollers are rendered ineffective. The impression mechanism is mounted on a detachable frame 156, the shaft 178 having a coupling 179 for engaging a coupling on a gear shaft 133. The machine prints amounts up to $20,999À99, words being printed by type-wheels 4 .. 9, Fig. 5, and type-segments 20, 23, and numerals being printed by type-wheels 32, 34, 36 .. 39. The cents type-wheels 4, 5 comprise types for printing the last six and the remaining letters respectively of the words thirteen to nineteen, both type-wheels being employed in printing those words. The dollars type-wheels 6, 7 have the same arrangement of types as the type-wheels 4, 5. The type-segments 20, 23 have types for printing the words hundred and thousand respectively. The typewheels 4 .. 9 and the type-segments have a row of asterisk-types normally at the printing line, and the type-wheels 4 .. 8 may have a second row of asterisk-types which is brought into the printing line when, as described below, the machine is conditioned for printing zeros to the right of the last significant numeral. The numeral type-wheels have types for printing numerals, zeros, and asterisks, the asterisk-types being normally at the printing line. The type-wheels are, as described in Specification 193,176, [Class 100 (iv), Typewriters &c.], carried by nested sleeves provided at the ends with pinions geared to pinions 75 engaging spring- urged racks 76 which are pivoted to stop-bars 77 and have stops 87 for engaging keys 79, and lugs 84 normally engaging a plate 85. When either or both of the type-wheels 8, 9 are displaced, either or both of the segments 20, 23 are depressed to present the word-types. For this purpose each of the pinions 75 associated with the type-wheels 8, 9 is provided with a collar 108, Fig. 6, having a recess normally engaging a pin 107 on an arm 106 which is connected to an arm 104 having a roller 105 arranged between a loose arm 99 and an arm 101 on the segment, these arms being connected by a spring 100. When the type-wheel 8 or 9 is displaced, the pin 107 rides out of the recess, and the arm 104 depresses the segment. The segments are each provided with a returning-spring 30, and a stop 28 arranged between lugs 26, 27. For causing zeros to be printed to the right of the last significant numeral, each stop-bar is provided with a lug 93 for engaging the plate 85, and a pin engaging a finger 96 on a rocking arm 94 arranged under the adjacent stop-bar at the left. On operation of the stopbar corresponding to the last significant numeral, all the stop-bars on the right are released and travel until they are arrested by the lugs 93, the corresponding numeral type-wheels being thereby turned to present the zero types. The word type-wheels are also turned to present the second row of asterisk, types. During return of the impression rollersthe racks and stop-bars are restored by means of a laterally movable rod 118 which is carried by rocking arms 117 and co-operates with pins 81 on the racks. The arms are connected to rocking fingers 121 engaging sliding locking-plates 88 for the keys. A rock-shaft 134, Fig. 2, connected to the arms 117 or locking-plates 88, has an arm 144 carrying a pawl 145 normally engaging a sector 142 which is loose on the shaft and is connected by a link 143 to a sector 127 operated by the crank 126. Normally the shaft is coupled to the crank and on return of the crank the racks, stop-bars, and locking-plates are restored. To permit correction of an erroneous setting, the shaft is rocked by a finger-lever 135. To permit of repeat printing, the pawl is released from the sector by depressing a repeat key 155, a lever connected to the key being connected to an arm 151 having a pin 152 for releasing the pawl.
