Abstract: 4760. Todd, L. M., and Tiefel, C. G. March 10, 1913, [Convention date]. Index type-wheel machines ; alining for impression roller-impression arrangements.-A chequewriting machine comprises a carrier to which are secured a number of type-formes for printing complete words or complete words and devices, the carrier being shiftable transversely to the reading direction of the types for selection and also being movable for impression. (1) In the machine shown, logotypes 9 are secured to a cylinder 10 which is splined on a shaft 11 and can be shifted longitudinally to bring any of the types over a roller-platen 4, the cylinder and the platen being then rotated for impression by turning a crank 21. The logotypes print the amount and the currency designation a word at a time and one of them can print a device such as a row of asterisks for use in filling up blanks. The cylinder is shifted by means of a sliding index 32 which is arranged over a scale 33 and is secured to a yoke 26 which engages the cylinder. (2) The logotypes are tapered at the leading ends, and are separated by grooves adapted to engage alioing- ribs 44. Two or more ribs are provided so that as a rule more than one rib at a time is operative. (3) The platen 4 is secured to a shaft 37 geared by pinions 35, 36, Fig. 5, to the shaft 11 which is geared through a one-way clutch to the crank. The shaft 37 is loosely mounted at one end in the base 1 and is journaled at the other end in arms 5, Fig. 8, secured to a rock shaft 6 and connected to a spring 14 which normally holds the platen below the bed 2 to permit insertion of the cheque. A cam 38 on the shaft 11 engages a roller 42 on an arm 40 secured to the shaft 6. The'cam is timed to lift the platen before the leading-ends of the logotypes reach the printing-point and to permit the platen to drop after the following-ends of the logotypes have passed, the following-ends being in alinement. The initial position of the platen is adjustable by means of screws 16, 17 mounted in an extension 18 of the arms 5 and engaging an abutment 19. The roller 40 drops into a recess in the cam when the parts reach the initial position, the recess holding the type-cylinder in the normal position with the logotypes at the upper part. In a modification, the rocking-device for the platen is omitted, the platen being formed with a flat which is normally at the top. Machines for embossing paper; paper-shields.- The platen co-operates with a paper-shield 62 to raise or emboss a continuous rib 118, Fig. 22, which receives the impression and thus renders fraudulent alteration, as by inlaying, more difficult. The shield is formed with a depression 64 having a cross-slot 65, the platen being of the same breadth as the slot and projecting into it slightly during impression. The shield thus protects the cheque from all the logotypes except that being printed from and the slot causes the part being printed on to be raised in the form of a rib. Machines for perforating paper; types and dies ; letter-spacing mechanism.-The logotypes and the platen are formed with transverse, diagonal, or longitudinal corrugations for shredding or perforating the impression and feeding the cheque through the machine, the feed at each impression being equal to the length of the logotype employed, plus a space. This result is due to the corrugations meshing with each other over an arc on each side of printing-point and thus causing the cheque to be fed not only through the length of the logotype but also through an additional space equal to the arc of engagement. In the case of transverse or diagonal corrugations, the platen and the logotypes gear through the cheque and feed it positively. If circumferential corrugations are provided, the feed is frictional. The feed is arrested by the descent of the platen upon release by the cam 38, the feed being adjustable by adjusting the cam ; or in the case of the modified platen provided with a flat, the feed is arrested when the flat arrives under the cheque. Paper-shelves; sheet feeding and guiding arrangements.-The cheque is placed on a detachable shelf 66, Fig. 8, which is formed with a flange or sidelay 80 and is moved laterally to bring the required line on the cheque into alinement with the platen. The shelf carries an adjustable end-lay 84 for determining at what part of the cheque the line is to commence. The cheque is pressed against the bed 2 by a feed-roller 93, Fig. 8, journaled in a yoke 94 fixed to a shaft 95, the axis of the feedroller being set slightly out of the normal with respect to the side lay 80 in order that the feedroller may press the cheque against the side-lay. The roller is pressed against the cheque by a spring 99, Fig. 7, on the shaft 95, and a plunger 100 connected to a lever 98 on the shaft is provided for raising the feed-roller. On depressing the plunger, a catch 104 pivoted thereon engages a lug 106 and locks the feed-roller in the raised position until it is released automatically by the engagement of a cam 110 on the shaft 11 with the catch. Printing-line indicators.-A fixed plate 81, Fig. 4, is formed with a T-shaped aperture 82, the part a indicating the width and position of the impression and the part b indicating the line on the cheque over which the impression is to appear. Roller inking-arrangements.-The logotypes may be inked by rollers 45, 46, Figs. 4 and 8, spring- mounted on doors 53, 54 which can be opened for re-inking. The wide roller 45 inks several logotypes after impression, and the narrow roller 46 inks the selected logotype before impression. In a modification, the ink-roller is of the same length as the cylinder 10 and is movable longitudinally therewith, the roller being preferably divided by disks into separate longitudinal sections supplied with inks of different colours, so that the logotypes may be arranged in groups, such as for currency designation and for numerical values, printing in different colours. The roller may be supplied with ink by means of an oil-can applied at an aperture in the cover 3..
