Abstract: 441,488. Printing-machines. QUICK, C. G., BENNISON, W. E., and ALEXANDER, D. A. H., 109, Borough Road, London. July 17, 1934, No. 20936. [Class 100 (ii)] Tripping-arrangements ; inking-apparatus.- In a rotary intaglio printing-machine the printing-roller 1 and the ink fountain 8 are mounted at each end in a common slide 3 which can be moved in guides 4 by mechanism operated from a piston 16, Fig. 4, arranged in a double-acting cylinder 17. The mechanism may be a shaft 12 operated by a rack-andpinion from the piston, and fitted with a cam 11, Fig. 1, acting on rollers 10, in which case arcuate surfaces 11<1> on the shaft 12 take the load when the cylinder 1 assumes printing position, thus assuring that the printing- pressure reaction is taken as a radial load to the shaft 12, thence as a compressional load to the bearing blocks 12<1>, and that the cylinder 1 always returns to the same position for printing. The piston 16 may, in a modification, operate slides 52, Fig. 7, with ramps 55 for operating the rollers 10, the slides being preferably mounted on rollers 53, and being formed with a horizontal upper surface 56 upon which the rollers 10 rest when the roller 1 is in printing position. The slides 52 are operated by rack-and-pinion mechanism from a shaft 60 which is oscillated by a segmental gear 61 engaging a rack 62 on the rod 15 of piston 16. In a further modification the slides 3 are operated by screw-and-nut mechanism from the piston 16. The shaft 12 is capable of being controlled by hand-operated mechanism comprising selflocking worm gearing driven by chain-gearing from a hand wheel, one of the worm gears being freely mounted on its shaft and being capable of connection thereto by a handoperated coupling on clutch device. The ink-fountain 8 with its furnishing roller 9 is mounted in slides 7 which can be moved in guides attached to the slides 3 by means of pinions 33 engaging racks 31 on the slides 7. The pinions 33 are operated by self-locking worm gearing actuated by a wheel 38, when it is desired to lower the fountain 8 relatively to roller 1 in order to permit of withdrawal of the roller 1 from its bearings 2. These bearings are rotated to allow of this withdrawal by means of a pinion 23 and rack 24 operated by a rack 25 and pinion 26 driven by worm gearing from a hand-operated shaft. The impression roller 11 may be mounted as described in Specification 441,283. Specification 441,540 also is referred to.

Filed: 1920-07-12
Abstract: 149,228. Kempewerk Nurnberg C. Kemp. Aug. 3, 1915, [Convention date]. No Patent granted (Sealing fee not paid). Intaglio-plate printing; drying-apparatus. - A machine for printing from an engraved cylinder is so arranged that the drive of the cylinders is automatically adjusted to suit slight variations in the size of the printing cylinder which at the commencement is made slightly larger than its normal size, so that it can be ground down successively to receive fresh designs, and be again used without loss of register. As shown, the printing-cylinder 1 is of slightly greater diameter than half the diameter of the impression cylinder 2, and the cylinder 1 is geared to a spur-wheel 4 geared to a wheel 5 on a driving-shaft 7, which also drives a wheel 6 freely mounted on the shaft of the impression cylinder 2. This wheel 6 is formed with slots 9 which engage pins 10 on the cylinder 2 and drive this cylinder during the non-printing portion of each revolution. During the printing portion of the revolution the cylinder 2 is driven frictionally from the cylinder 1, and the cylinder 2 can move more quickly than the wheel 6 and the pins 10 move forwards in the slots 9. This relative movement of the cylinder 2 and wheel 6 causes an arm 14 on a shaft 13 geared to a wheel 11 on the cylinder 2 to move outwards, and when a roller 15 on this arm engages a fixed cam 16, the arm 14 is moved inwards, and the cylinder 2 is retarded and the drive is again taken up by the wheel 6. In the Specification as open to inspection under Sect. 91 (3) (a) it is stated that the sheets are delivered to bands by a drum which is perforated around its periphery and formed with a fan which produces an air current to assist in the drying of the sheets as they are delivered face upwards. This subject-matter does not appear in the Specification as accepted.

[Class 100 (ii).] A printing-plate having mercurial non- printing areas is prepared by coating a metal amalgamable with mercury with a non-amalgamable metal, applying the design in a resist to the coating, etching the unprotected parts to expose the lower metal, amalgamating the exposed parts with mercury, treating the amalgamated surfaces with a suitable fluid, e.g. a solution of silver nitrate and nitric acid, to produce a layer of mercury silver amalgam having a matt surface, and again amalgamating the treated surfaces with metallic mercury. A base of copper or brass, or of other metal coated with copper or brass, is provided with a coating of nickel on which the design is produced in a resist of e.g. bichromated fish glue, and the nickel, and, if desired, some of the underlying copper is etched away by perchloride of iron. The plate is then treated with a solution of mercurous nitrate and then with metallic mercury. The plate is afterwards treated with a solution of nitrate of silver and nitric acid until a matt surface is obtained, after which it is rubbed with metallic mercury. The Specification as open to inspection under Sect. 91 states also that the non-printing areas may be replenished with mercury during the printing operation by adding mercury to the ink or by spraying mercury on to the inking rollers. This subject-matter does not appear in the Specification as accepted.
