Abstract: 8829. Allison, C. A., [Kavenaugh, J. T.]. April 27. Labels.-Relates to a machine for making and stringing labels B of the form shown in Fig. 1, and for collecting them in counted batches. A strip of paper is fed by the sliding carriage a, on which it is held during the forward stroke by a presser a<2>. Punches b<2>, b punch holes in the strip, cut out the label, and drive it between the gripping-fingers c, which then carry it forward to the stringing-device. The string is passed through the label by a needle f, and gripped on the under side by grippers d, which then turn upwards along the dotted line shown in Fig. 25, to lay the string over pins on the end of a lever i. The latter descends and draws out a loop of the string, and the doubled end of the string is then engaged by the hooked arms e<18>. These draw the string into the tube e<14>, which rotates to form a loop through which the arms e<18> are advanced to grip the free ends of the string, which has been severed by shears h. A jerk of the lever i pulls the loop off the arms e<18>, over the cut ends of the string, and completes the knot. A hook on the rotating arm k is now brought up to remove the label and to transfer it to an arm l on the collecting - wheel. This is advanced to bring an empty arm l into position by a pawl actuated from the arm dropping into a deep notch on the counting-wheel m, and thereby actuating a ratchet advancing-gear. The various parts, shown in detail in the Specification, are actuated from two cam shafts j, j<1>.
