Abstract: 435,855. Typewriters &c. WARD, E. J., 4, Park Place, St. James's, Westminster. Oct. 19, 1934, No. 30512/33. [Class 100 (iv)] Roller-impression arrangements; index. type-wheel machines.- In machines for printing amounts on cheques &c., one or more impression-rollers are traversed across the cheque by means of a handlever which is associated with toggle-mechanism for moving the impression-rollers into and out of contact with the cheque at the beginning of the direct and return traverse. The machine may comprise type-wheels set by setting-racks provided with means for setting the type-wheels to printing noughts to the right of the highest significant figure. In the machine shown in Figs. 2 and 3, groups 11, 12 of type-wheels for printing numerals and words are geared in pairs to pinions 14 gearing with racks 6 which are provided with knobs 22, and pointers 23 arranged over indexscales 7, movements of the racks rotating the associated pairs of type-wheels to set up an amount in numerals and words. Impressionrollers 46 are secured to a shaft yieldingly mounted in a block 73 which can slide on a bar 75. The impression-rollers are arranged opposite slots 47 in a guide-shoot 45 for the cheque and are normally out of contact with the cheque. The block 73 engages a slotted lever 67 connected by a link 65 and arm 63 to a shaft 61. A sector 60 on the shaft engages a rack 55 operated by an arm 51 on a shaft 49 operated by a hand lever 48. The bar 75 can move laterally in forked arms 77, and is connected to toggles 95, 93 and 97, 96, the members 93, 96 being pivoted on the framework, and the members 95, 97 being connected by a link 104. The toggle 95, 93 is connected by a link 91, arm 89, and shaft 86 to a sliding rod 82 which co-operates with a star-wheel 52 having one-way connection 107 with the shaft 49. When the hand lever is pulled forwards, the star-wheel is effective to straighten the toggles, and the bar 75 is moved laterally to bring the impression-rollers into contact with the cheque, engagement being maintained by means of a dwell on the operative tooth of the star-wheel. On further movement of the hand lever, the block 73 is traversed, and the impression-rollers move along the cheque. Near the end of the traverse, the star-wheel releases the rod 82, and an abutment 113 on the block engages the togglemember 97, the toggles being thereby opened, and the bar 75 being moved laterally to remove the impression-rollers from the cheque. When the hand lever is moved backwards, the impression-rollers are returned. The racks 6 are mounted in a slotted support 4 and have longitudinal slots engaging a rod. Spring- plungers co-operate with teeth to retain the racks in set position. For setting the typewheels to print noughts to the right of the highest significant figure, the racks 6, abut on cams 31, Fig. 6, mounted independently on a shaft 33, each cam, excepting that for the pence setting-rack, having a spring-urged pawl 36 engaging a notch 38 in the associated rack, and a pin 42 engaging a pin 43 on the adjacent cam. Operation of the rack for the highest significant figure rocks the associated cam, and the remaining cams move their racks into the nought position. Specifications 193,176, [Class 100 (iv)], and 362,463 are referred to.
