Abstract: 29,388. Hollingsworth, S. Dec. 17. Number-printing apparatus; holders for loose types and the like; printing and embossing surfaces.-Relates to numbering-machines particularly for use in printing manifolding counter-check books of the kind in which the numbering - heads are removably carried by cylinder segments and are actuated by small shafts journaled in the cylinder segments, and consists in providing each segment with a closed-ended longitudinal channel having an enlargement at one part to permit the numbering-head to be inserted and adjusted longitudinally in the segment while the segment is on the cylinder shaft. The segments 18, Figs. 2, 3, and 7 are adjustably mounted upon a shaft 9 by means of screws 19 engaging dovetailed grooves in flanges 17 upon the shaft, and are provided with channels having end enlargements 20 for the insertion of the numbering-head holders 22, and side grooves 21 to receive tongues on the holders. The shaft 9 is mounted in eccentric bushes 10, by means of which the numbering-heads may be adjusted towards or away from the impression cylinder. The numbering-wheel operating-mechanism may be of any suitable form having a pawl frame actuated by a grooved oscillating shaft engaging a tongue on the frame. The grooved shaft 26 extends to the opposite enlargement 20, and is oscillated by means of a crank 24 and roller 25, engaging a cam-groove 16 in a disk 15 adjustably fixed upon an extension of one of the bushes 10. The end of the groove in the shaft 26 is flared at 27 to allow of the insertion of a numbering-head in all positions of the segment 18 relative to the cam 16. The segments 18 may be of different sizes, as shown in Fig. 7, according to the required positions of the numbers on the running web of paper. The shaft 9 is driven from the main gear of the machine by means of a gear-wheel 29 loose upon the shaft 9, but fastened by nuts 30 to a conical collar 28 on the shaft after the segments 18 have been adjusted relative to the web. For printing unchanging matter, type-holders 34, Fig. 8, may be inserted in a cylinder segment after removal of the shaft 26. The type 35 are fixed by a set-screw 36 and the holder 34 is secured in the channel by a conical-ended bolt 38 and bevelled plug 37 which are forced against the sides of the channel by a conical screw 39. The numbering-head holders 22 are similarly fixed in the adjusted position. For printing clerk or department numbers or other matter in repetition close to the consecutive numbers, small stereotype plates 32, Fig. 9, are placed upon the segments directly over the numbering- heads 22 and are held in place by bevel-edge clamping - blocks 33 carried by nuts engaging spiral dovetail grooves 31 cut in the segments. Fig. 1 shows diagrammatically an arrangement for printing both sides of a web of paper 1. Each impression cylinder 3 is provided with two pairs of numbering - cylinders 8 constructed as described above, and each pair of cylinders is provided with a separate inking-device 4, so that the numbers may be printed in different colours. The numbering-cylinders are of such a length that several orders may be executed side by side upon a single web.
