Abstract: 9672. Perry, F. J. April 29. Embroidery.-Relates to improvements in cording-apparatus of multiple embroidering-machines of the type described in Specification No. 213, A.D. 1902, and consists in moving the reel - carriers and cording-guides simultaneously round their respective needles, by longitudinal bars C, D so as to dispense with gearwheels, without twisting the threads. Each of the reel-carriers B is pivoted to an arm I<2> extending from a sleeve I mounted on a needle-bar A', a guide B<5> for the cord a being also attached to the sleeve I, and rotating with it. A shaft M, driven from the main shaft of the machine, carries cams for actuating a rocking shaft K, arms K<1> of which engage in longitudinal slots in the bars C, D, and cause them to move simultaneously up and down in front of guiding-supports J, against which the bar D is held by brackets J<1>. The two bars C, D are clamped together in such a manner that they can also be moved independently of each other in opposite directions longitudinally, by cams T, T<1> mounted on axles U and operated by bevel gearing from the shaft N. The combined movements of the bars C, D cause socket ends of members N, N' secured, respectively, to the bars C, D, to move in semicircular paths P, P<1>, Fig. 2, so that the member N' engages with a pin O<1> on the reel-carrier B, and moves the latter half-way round the needle-bar A<1>. The other member N then engages a second pin O and moves the reel-carrier back again the remainder of the way round, the latter being prevented from returning, during the transference from one member to the other, by the simultaneous engagement of the members N, N' with the pins O, O<1> just as the reel-carrier is transferred from one socketed member to the other. In another arrangement, Fig. 4, each of the reel-carriers B is provided, on its underside, with a clip B<3> which fits on one of a number of longitudinal guideways C<1> formed along the upper edge of the bar C, and as the latter is reciprocated vertically by means of an arrangement of levers cam-actuated from a driving-shaft mounted at the end of the machine, it carries the whole of the reel-carriers with it, notches being formed in the upper edge of the bar C to receive the needle-bars A', when the bar is raised to its upper position. The bar D, which is also actuated from the driving-shaft, is placed on the inner side of the bar C, and is provided with a series of vertical members D', which form vertical guides for the reel-carriers B. The bar D is reciprocated longitudinally so as to move the reel-carriers B alternately from one side of their respective needlebars A<1> to the other, and the combined movements of the bars C, D cause the reel-carriers to move in an approximately square or circular path, round their needle-bars. Each reel-carrier B is provided with an extension B<5>, which serves as a guide for a cord a, the latter being secured to the work by the needle thread in the process of embroidering. The cord passes through an eye B<6> in the extension B<5>, and then through an opening in a device H placed close to the fabric being operated on, and secured to a bar H<1> carried by brackets R<2> secured to a rail F. A spring-controlled arm is arranged to press on the lower flange of each of the reelcarriers B, to serve as a tension device for the cord a. Fig. 13 shows another form of thread-guide, in which an arm B' is connected to the end of the extension B<5> by means of a tubular pivot B<8>, through which the cord a is carried, passing thence through an eye B<9> in the end of the arm B<7>. The arm B' is rotated about the pivot B<8>, during the rotation of the reel-carrier B, by a fork d, which engages round the needle-bar A', the latter, in this case, being, preferably, tubular, and having the needle thread passed through it.
