Abstract: 173,858. Walker, R., and Blackford, J. Oct. 7, 1920. Carding-apparatus. - In apparatus for sticking needles, pins, &c. into paper means are provided for advancing and gripping the material in a position convenient for inserting the needles, &c. by hand or by machines operated by hand or power. In a machine for this purpose the material 10, Fig. 9, is gripped by three strips 1, 2, the outer of which 2, press upon the edges and the middle of which, 1, presses under the middle of the length of material 10 so that the needles &c. can be pushed through the middle, which bulges up over the middle strip 1. The strips 2 are connected together, and are adapted to be moved out of the plane of the strip 1 to release the material, or, instead, the strip 1 may be moved. Fig. 1 shows a method of moving the strips 2, which are mounted on spring-pressed columns 3 connected by a bar 40 carrying inclines 39 actuated by inclines 38 on a bar 37 oscillated by a hand-operated lever 34. The material 10 may pass over a weighted jockey-pulley 56 and be wound on a reel 12 at the forward end, its rear end being alternately held and released by a reciprocating feeder, shown separately in Fig. 6. This feeder comprises a spring-pressed sliding jaw 22 moving in a slot 21 in an outer jaw 20, the jaw 22 moving up and down to release and hold the material 10 passing through the slot 21 by the partial rotation of a stem 25 having pins 27 guided by slots 28. The stem 25 is rotated by an arm 26 thereon engaging stops 50 during the reciprocation of the feeder, which is effected, through the medium of a rod 31 and a bridgepiece 33, by the lever 34. The lever 34 also causes the reel 12 to advance by a pawl 16 actuated by the bar 37 through a pivoted link, a spring-pressed rod 45 and an arm 46. Where two rows of needles, &c. are to be stuck into material of circular, square, or other shape, two groups of three strips may be employed, the material being carried on a table rotated step by step. For the automatic sticking of needles, &c. a housing 70 may be provided adjacent to the strips 1, 2. The housing 70 contains holes 72, in each of which is located eccentrically a rotarv conveyer 73, Fig. 12, having one or more longitudinal grooves 75. The holes 72 are connected to the top and bottom of the housing 70 by slots 71, into which the needles, &c. pass from hoppers 74. Partial rotation of a conveyer 73 causes a single needle to be transferred from an upper slot 71 to a lower, where it is in position for being pushed through the material 10. Simultaneous rotation of the conveyers 73 is effected by oscillating bars 81 carrying pins 80 which engage in slotted crank-arms 78 on the conveyers. The bars 81 may be actuated by the lever 34 or by another hand operated lever. The conveyers 73 may be mounted in detachable bearings held in place by plates 102, Fig. 9. Adjustable thin metal pushers 91<a> mounted on a sliding bar 90<a> may be provided for forcing the needles, &c. into the material 10. A riding roller 105 is preferably provided to hold the needles, &c. flat before pushing them into the material. The needles &c. are preferably arranged in groups, a few needles, &c. of each group being forced into the material at each operation of the apparatus.
