Abstract: 430,177. Printing-machines. SMITH, L., 133, Oakwood Court, Kensington, and PARCELADS, Ltd., Africa House, Kingsway, both in London. Dec. 20, 1933, No. 35883. [Class 100 (ii)] Rotary machines; tripping - arrangements.-In machines for issuing gummed paper strip, of the kind comprising a casing carrying one or more rolls of strip paper, one or more rollers for printing on the strip, means for applying gum (or damping the gum if already applied) on the strip, means for facilitating the breaking or cutting off of issued gummed and printed paper, and means for tripping the printing- rollers, each printing-roller is freely mounted upon a spindle which is provided with projecting members spaced apart upon the spindle and adapted to engage fixed abutment members, means being provided for rotating the spindle so that the projecting members may be brought to engage the abutment members and thereby trip the roller against spring bias. The machine shown comprises a casing 1 provided with a hinged cover 18, and an inner frame comprising two side walls 8, spaced from the side walls of the casing and adapted to support the whole apparatus. A roll 3 of gummed paper is supported on a spindle 2 mounted in slots 9 in the walls 8, and is adapted to rub against the walls 8 to impose a frictional resistance to the pull of the paper strip, or spring plates or other braking means may be employed on the roll. The printing means comprises a roller 4 of wood &c., having a rubber-type printing-surface 5, freely mounted on a spindle 6 mounted in open slots 7 in the walls 8. Two arcuate plates 10 fixed on the outsides of the walls 8 adjacent and beneath the spindle 6 are adapted to co-operate with a pair of radial parallel pins 11 screwed or otherwise secured to the spindle 6 to raise the spindle and, consequently, the printing-roller 4 when the spindle is turned by means of a handle 12 to bring the pins into engagement with the plates. The plates 10 are preferably provided with depressions adapted to be engaged by the pins 11 when the latter are pointing vertically downwards. The spindle 6 is normally biassed downwardly by wire springs 13 secured to each side wall 8, but when it is desired to remove the printing-roller the springs are lifted and placed on tongues &c. 17 on the walls 8. The paper strip passes from the roll 3 around two guides 23, contacts with the printing-roller 4, passes over a further guide 23, then between rubber-covered feed rollers 27, one of which is rotatable by means of a handle 29 and is spring-pressed by a spring 28. The strip then passes to a damping brush or piece of felt 24, arranged in a water bath 25. The strip may be torn off against a guillotine or saw edge 26. The tension in the paper strip keeps it normally in contact with the printing-roller 4, but a resiliently mounted bed may co-operate with the roller, if necessary. Inking-apparatus.-The printing-roller 4 is inked by an ink-impregnated felt or like pad 19 carried in a metal casing 20 provided with a flat spring 22, the ends of which are received in slots 21 in the walls 8 of the machine.
