Abstract: 11,286. Panitschek, H. May 14. Shuttleless looms. - Horsehairs are withdrawn from a trough-shaped magazine a, Fig. 1, and are placed one at a time into a position from which they are laid in the shed by a " shuttle " s, Figs. 10 and 11, having forked parts. The horsehairs are first acted upon by a withdrawing-gripper I, Fig. 5, which has two fixed parts 1, 2 and a normally spring- closed jaw 3 between them, to prevent a hair grasped by the gripper from being bent. The jaws are curved so as always to make the same angle at the point of intersection of the gripping - edges for different relative positions of the jaws, and the jaw 3 is provided with notches 5 increasing in depth from its point of rotation. Hairs of varying thicknesses are pushed out to various extents until they are clamped in the notches of appropriate depth. The withdrawing- gripper, carried on a cam-actuated lever b, enters the bundle of hairs, its jaw being opened by a stop 6, and it then moves to the right off the stop. The jaws are thus closed and the gripper descends, its jaws being opened by a stop. The gripper then returns to the left (but not to its initial position), and the same hair, or one previously withdrawn, is grasped at a point more remote from the magazine and fed to a supplying and transferring gripper II, Figs. 1 and 6. The withdrawing-gripper then returns to its initial position, and as the hairs are of different lengths, a tuft of hairs extending different lengths from the magazine is gradually produced by the movement of the gripper I. The gripper II is provided with feeling-jaws 8 connected to clampjaws 9, the latter being allowed to close only when the farthest withdrawn hair has just left the feeling-jaws. The hair is then clamped between the jaws 9, which are closed by the forked ends of a leaf spring 10. The jaws are opened by the wedgeshaped nose 13 of a pin 12, which slides in a bracket 11 carrying the spring 10 and is operated by a stop and bell-crank. The supplying-gripper II is carried by a cam-actuated lever c which rotates on a shaft e. A lever d, which carries a shot guard IV provided with a feeling-finger 22, rotates on the shaft e and is sustained in its raised position by a movable stop 24. When the last downward and forward movement of the withdrawing-gripper is completed, the feeling-finger 22 is released from the stop, and descends, moving a hair into the opened supply gripper II. The hair prevents complete descent of the finger 22, however, so that an arc-shaped piece thereof covers up a slot in the upper part of the lever d and the latter in its downward movement rotates a guard-finger f about the shaft e, dobby mechanism being thereby put into gear, so that the shed is changed. If no hair is fed into the supply gripper, the finger 22 descends completely and the arc-shaped piece uncovers the slot, so that the guard finger is not moved and the shed is not changed. The lever arm d' is made longer than the lever arm c', so that the shot guard IV lags behind the supply gripper II. The horsehair 27 is thereby placed transversely in front of the shed opening, to be laid in the shed by the shuttle. A stop 32, which acts on the sleeve carrying the carrier II, by special mechanism swings the supply gripper outwards so as to bring the hair near the edge of the fabric iu order that it may be utilized along its entire length. When the shuttle enters the opposite shuttle box, it presses a tongue 33 and, by lever mechanism 34, 35, shifts the pin 12 so as to open the supply gripper. To hold the tuft of hairs fast while the supply gripper slides along the hairs, a holding-gripper III, having fixed parallel jaws and a jaw moving between them, is used. The jaws are closed by a spring and opened by a sliding rod. They embrace and clamp fast the lower part of the bundle and the projecting hairs. This gripper III also effects a uniform supply of hairs at the lowermost part of the magazine. In a modification, to avoid the hairs being seized twice, two withdrawing-grippers I, I', Fig. 18, are used, one acting on the hairs in the magazine and the other one on the already withdrawn tuft of hairs.
