Abstract: 20,891. Scheid, A. M. Sept. 20. Cards, punching.-In punching-machines, reading- in or punch-selecting apparatus is provided which enables a number of pattern repeats to be produced automatically at one operation. The punches may be operated directly or through the medium of lifting-knives B, Figs. 1 and 2, needles C, and hooks A, to which the punches or punch abutment keys are pivoted or connected by cords A<1>, The needles C are pushed inwards by pushing-needles N, passing through holes in an exchangeable guideplate P, and resting on angle-bars M<1>, by which they are pushed forward when raised by feelerneedles O, adapted to be raised by bars K operated by keys L. There are as many keys and bars K as there are needles C in a vertical row, and as many series of feeler-needles as repeats required. Thus, there may be eight needles C and corresponding bars, and with four repeats, 32 feeler needles in four series, each series of eight needles being not necessarily in the same row but in two adjacent rows, where the repeat is required to start in the middle of a row. The needles N, O, &c. are carried in a sliding frame F<2>, F<1>, F<3> provided with supports G<1>, G<2>. The latter carry rollers H. sliding between rails J<1>, J<2>, the upper one being removable so that the carriage may be detached. The frame is adapted to be moved step by step, so that one vertical row of needles and the corresponding row or parts of two rows in the repeats may be moved to the next vertical row or rows, by any such device as is issued for the paper carriage of typewriting-machines. In some cases, a space is required to be left in one of the repeat sections, say a space W-W, Fig. 4, of four vertical rows in the third section, Figs. 4 and 13, for lacing-holes, four vertical rows of punches C being omitted. In this case, the bars K control another and equal set of pushing-needles N' and lifting-needles besides the needles N, the needles N' being placed four rows in advance of the needles N. The needles N, N' are passed through slots p<1> in the plate P, and through holes in slide strips Q, Q<1>, respectively, sliding on an adjusting-bar U against which they are suitably held by springs V. As the strips Q, Q<1> slide along with the carriage, the needles N in the slide Q are first raised into action and the needles N<1> raised out of action, and then the slide Q<1> is lowered into action in readiness to operate the required punches in the subsection beyond the space W, as shown in Fig. 4. When this space has been passed, the slide Q has meanwhile been lowered to place the needles N out of action. The pattern thus skips over the space for lacing and peg holes. In a modification, where the lacing space is greater than one of the subsections, one of the slide strips can be dispensed with. The needles O for carrying the pushing-needles are guided by means of hooks in the top plate or grate S, their lower ends passing through a hole plate T above the bars K. The needles N, N<1> are returned by springs N<3> acting against collars N<2> thereon. The needles Care gaided by grates D<1>, D<2>, the latter being provided with springs C<1>. The needles C may be returned by a reciprocating plate behind the grate D<1>, or by a card prism E arranged to operate against needles E<1> for enabling cards to be copied. The copying- device might also consist of a fore-needle device as in the " Verdol " " mechanism.
