Abstract
173,775. Eberhardt, H. Jan. 5, 1921, [Convention date]. Embroidery machines of the Heilmann type, and having revoluble cylindrical take-ups surrounding the needle-clamps, are provided with mechanism for re-threading the needles. The needleclamps N form part of bars 1<c> which are reciprocated by means of a cross-bar 22 and a lever 24 from a rocking-spindle 25, and are intermittently rotated, together with take-up cylinders 12, from a shaft 17. The clamps N can be opened, when in their forward positions, by the withdrawal of keys 4 in the rods 1<c> by means of levers 38 and a rocking- spindle 43. When the thread is being pulled through the fabric by means of the take-up cylinders, guide-rods 44, 51 are moved to the positions shown in Fig. 2 so that the thread is pulled straight, and is wound correctly on the cylinder 12. To remove the thread-ends from the needles a lever 55, Fig. 1, to which are attached bands 56, 57, is rotated so that the needle clamp N is reciprocated through holes 57<a> in the bands; on the return of the clamp, the lever is partly raised, and cutters 58 sever the knotted thread loops. Thread from a spool 94, Fig. 2, passes between tension discs 73, through guide-bars 68, between prongs on a bar 66, and is held in a thread clamp 70 on a bar 67. In the threading operation, the bar 66 is moved longitudinally to the position shown in Fig. 9, and is then turned upright by the longitudinal movement of inclined surfaces on a bar 66b. The bars are then moved to the position shown in Fig. 12. A hook 79, Fig 2, which is actuated by moving a stepped bar 90 now descends through the needle eye, and draws the thread up through the eye. The apparatus is then moved to the position shown in Fig. 13. The opposite clamp pulls the needle and threadend through the thread-loop, and the material to set the knot and winds a thread supply on its cylinder, after which shears 76, 77, mounted on a lever 74, cut the thread, the loose end of which is again held by the clamp 70. Specifioation 173,776 is referred to.
