Abstract: 150,821. Errington, G. A. June 10, 1919. Index type-wheel machines; type-wheels; index type-band machines; machines for perforating paper; letter-spacing mechanism; hammer-impression arrangements.-Relates to a machine for filling in cheques, of the kind which comprises a set of type-wheels bearing loose types which are of different lengths and can be moved longitudina.lly to justify or equalize the spacing. (i) The amount is printed in words by types 26 permanently mounted on a series of type-wheels 24, Fig. 2. the types being of different length, corresponding to the length of the words, and the types on all the wheels except that at the extreme right being movable longitudinally. The movable types are formed with lugs 100, Fig. 10, which engage. slots 98 in spacing-flanges 28<x> on the type-wheels and are held in contact with the ends of the .slots by blade springs 101. In the machine shown there are eight type-wheels for printing the number of dollars in words, two type-wheels for printing the number of cents in numerals, and a typewheel for printing the word " cents." The typewheels can also print protection marks at the beginning and end of the amount. The type-wheels are mounted loosely on a shaft 22 and are provided with setting-levers 30 which pass through slots 16<x> in the casing 1 and are set with reference to index marks on the casing. The setting- levers are mounted loosely on the shaft 22 and engage notches 28<1> in the flanges 28<x>. When the type-wheels have been set, the selected types are in alinement at the bottom of the type-wheels and are in position to co-operate with an impression hammer 74, described below, having a serrated face which squeezes and incises the cheque and forces ink into the fibres. Before the hammer is operated, the loose types 26 are moved longitudinally by a manually operated slide 102, Fig. 1, until they abut on the fixed type on the end type-wheel. The slide 102 is formed with a type-engaging arm 102<x>, guided by a sleeve 103, and a guide arm 102<1 >which passes into a tube containing a returning-spring. The arm 102x is formed with teeth engaging a detent 107 which locks the arm in the inner position. A releasing- lever 110 is provided for the detent. The set amount is displayed through a slot 11 in the casing by endless bands 50 which bear the same series of words &c. as the types, and are geared to pinions 28 on the flanges 28<x>. (2). The payee's name is printed by type-wheels 23 having fixed types 25 which co-operate, with a serrated impression hammer 73. The type-wheels are mounted on a shaft 22 and are provided with setting-levers 29 which project through slots 15<x> and are set with reference to index marks on the casing. The payee's name when set is displayed through a slot 9 by endless 'bands 38. (3). Manually-set devices 143, 142, for printing in numerals the amount of the cheque and for printing the date respectively, are adjustable laterallv to print in the required position, and are movable vertically for impression in oo-operation with a serrated plate 193 for cutting fine slits in the cheque. The devices are identical except as regards the number of types, and are constructed in the following manner. The types are mounted on endless chains 152, Fig. 11, passing over drums 147 and blocks 148 which are mounted on shafts carried by a box 144. The drums are associated with setting- levers 156<x> having spring-pressed pins 161 which co-operate with ratchet-teeth 156 on the face of the drums, the setting-levers being reciprocated to advance the types. The set date or amount is displayed through a slot 192 by endless bands 191 which are geared to the drums. The box 144 is supported on a bar 162 which is secured to the main casing 1 and is provided with sliding collars 165, Fig. 1, and 165<x>, Fig. 12, having vertical guides 167 which receive T-ribs 163,164 on the box. The box is secured in the adjusted lateral position by means of a screw 178. The box is depressed for impression by means of a plunger 170 which abuts on the box and is guided by a sleeve 166, arranged between the collars 165, 165<x>. A returning-spring 177 for the box is arranged in a tube on the box and abuts on an arm 174 on the sleeve 166. Usually, the devices 143, 142 are placed at the right side of the machine, but for Canadian cheques, the devices and a co-operating serrated plate 196 are placed at the left side of the machine. (4). The hammers 73, 74 each consist of a channel bar 75 provided with a number of plates which rest on a rubber strip 76 and are formed with sharp serrations for incising the cheque. The channel bans pass through slots 71, 72, left between plates 68, 69, 70, and have pin- and-slot engagement with levers 83, 83<x> geared to shafts 86, 89 which are operated by cranks 87, 97. (5). The main casing 1 is formed in the side walls with slots 57, 58 for the insertion of the cheque. The cheque is supported inside the machine by the plates 68, 69, 70 and is supported outside the machine by tables 113, 241. The plates 193, 196 are flush with the table 113, The cheque is first placed on the table 113 to receive successive imprints from the devices 142, 143 and the typewheels 23, and is then moved on to the table 241 to receive imprints from the type-wheels 24. Alining for impression.-The setting-levers 29, 30, Figs. 1 and 2, for the type-wheels 23, 24 are formed with lugs 31<x> for engaging alining-notches at the sides of the slots 15<x>, 16<x>. Roller inking-arrangements.-The type-wheels 23, 24 are in contact with inking-rollers 39, 40, Fig. 2, each mounted on a wire 41 which is carried by nuts 44, Fig. 1. on the casing, and is urged upwards by springs 47. The rollers are made in longitudinal sections consisting of a core of cord and a cover 39 of felt. Pad inking-arrangements.-The devices 142, 143 are each provided with an inking-pad 184, Figs. 1 and 12, supported by a bell-crank 180 which is pivoted on an arm 179 on the sleeve 166 and is formed with a slotted arm 180<x> engaging a pin 181 on the box 144, the pin causing the pad to move laterally when the box is depressed for impression. The pad is provided with lugs 185 which are pivoted on a rod 185<x> extending between the bell-crank and an arm 183 thereon, a spring 186 on the rod urging the pad towards the types. Sheet guiding and clamping arrangements.- The table 113, Fig. 1, is provided with an end gauge 114 for the cheque, consisting of a flanged member which can be adjusted longitudinally and laterally and is secured by a screw 119, passing through a slot 117 in the table and a slotted arm 118 on the gauge. The table 113 is also provided with a laterally movable gauge 121 which engages the top of the cheque and is employed for adjusting the cheque with reference to the type-wheels 23. The gauge passes through the slots 57. 58 and is engaged by an adjusting-screw 126. The gauge passes over a scale on the table 113 and is formed with a pointer co-operating with a scale on the slot 58. The table 241 is provided with a gauge 132 which is movable laterally by means of a screw 133 and is employed for adjusting the cheque with reference to the type-wheels 24. The gauge is provided with a cheque-clamp consisting of a base 139 and a spring top 140 which can be raised or lowered bv means of a hand-lever 141 having an eccentric part engaging the top 140. The base 139 is formed on a longitudinally adjustable strip 136 which rests on a flange, 135 on the gauge and is provided with a headed pin engaging a slot in the gauge. Paper-shields.-Shields consisting of pairs of spring plates 64, 65 and 66, 67 are arranged below the type-wheels 23, 24 respectively.
