Abstract: 6087. Toone, F. A. S. March 12. Record-controlled machines for checking jacquard cards.-In order that punched jacquard cards for curtain-lace machines and tapestry and other looms may be checked and corrected, they are passed through a jacquard, the hooks 11, Fig. 5, of which are connected to printing-needles 1, Fig. 1, whereby coloured marks are made on one or more strips of paper 16, the cards being passed several times through the jacquard if desired, and differentcoloured marks being printed on the paper, whereby a coloured draft of the pattern is reproduced from the cards. This draft is compared with the original draft, and the cards are correspondingly corrected. The needles 1 are acted upon by springs 9, and the printing-paper 16, perforated at both edges, is fed forwards over a printing-roller 12 by a pegged roller 18, intermittently and adjustably rotated by ratchet mechanism. Spring fingers 26, 27 hold the paper against the rollers 18, 12. Driving-pegs may be mounted on the printing- roller, which is arranged vertically below the printing-needles and has a vulcanized-rubber covering or other printing-surface. The printing-roller is vertically reciprocated in end bearings 13 by eccentrics and connecting-links 15, or by cam-andlever mechanism. The printing-ribbon 17 is passed over rollers 30, its ends being attached by clips to rollers 28, 29, which may be provided with brake mechanism and have ratchet-wheels 31, 32, one of which is driven by a pawl 33, so that the ribbon is moved in one direction or the other. The jacquard needle hooks 11 each have two hooks, and the grid 34 has an extra lifting-knife 35, so that by changing the grid relatively to the knives the needles may be pushed on to or off the lifting-knives by blanks on the cards. The odd and even numbered printing-needles may be cranked or inclined in opposite directions to bring the printing-points closer together. In a modification, cranked spring- wire needles 40, Fig. 3, fixed to a bar 42, and connected at 47 to the strings in connexion with the jacquard are used, the printing-ends sliding in holes or slots in plate 41. In another modification, the printing-needles 50, Fig. 4, have collars 53 provided with catches 56, which can be engaged by spring-controlled slides 57. The needles required to print are raised above the slides 57 by the jacquard machanism, and are then lowered on to these slides, which are afterwards withdrawn by a bar 59, whereupon the printing-needles are shot downwards by compression springs 51 so as to make marks on the paper, the needles being withdrawn by buffer springs 52. The catch mechanism may be dispensed with, the jacquard grid being allowed to fall quickly. The printing-needles may be arranged horizontally, vertically, or inclined, and may consist of levers. The ribbon may be raised and lowered relatively to the paper. The machine may have two or more ribbons of different colours. The manner in which the machine is used with different types of cards is described.
