PICKIER DEVICE FoR' LOOMS.

SPECIFICATION forming part of Letters Patent N 0. 665,904, dated January 15, 1901.

Application filed October 10, 1900. serial No. 32,585. (No model.)

To all whom it may concern:

Be it known that I, J OSEF HIEBEL, a subject of the Emperor of Austria-Hungary, residing at Aix-la-Ohapelle, Germany, have invented certain new and useful Improvements in Picker Devices for Mechanical Looms, of which the following is a specification.

My invention relates to a picker or shot device for mechanical looms, its object being to preventa break in the beat-u p when the lathe is inthe wrong position.

In the accompanying drawings a device of this kind is represented in Figure 1 for the left side, and in Fig. 3 for the right side, of the loom in two different positions. Fig. 2 is a side View of the device; Fig. 4, a View of the lower part of the device on a larger scale. Fig. 5 is a side view of the stop-slide for the picker-stick. Fig. 6 is a top view of the bolt connected with the pivot of the picker-stick.

The movement of the batten is efiected by the eccentric a, Figs. 1, 2, and 3, which moves at every revolution the angle-levers b, and by the connecting-rod c the batten-sector d.

On the batten-shafts e are situated loosely the batten-levers f, which are carried along by the sectors or drivers at in the manner as may be required by means of the clicks or bolts 9 and h. The batten-levers f are connected by drawing-bands t' with the pickersticks k. The picker-stick has its pivot on a bolt q, Fig. 6, provided with two pins, said bolt beingjournaled in the slot .2, Figs. 1 and 3. When the picker-stick It is moved by means of the band 2', it revolves around the point Z and gives the picker or driver the required motion for the shot or pick in the direction of the arrow. The picker'stick is, Fig. 4, is fixed in the picker-shoe 0, which catches over the guiding-arm p and revolves around the lateral pins Z of a bolt g. This bolt is journaled horizontally in a slot 2 of the guiding arm 10 and presses by its rear extremity t on the slide it, Figs. 4 and 5, which is connected with the shuttle-box, so that it is raised and lowered with the same. When the pickerstick it is moved by the band '11 in the direction of the arrow for the purpose of throwing the shuttle out of the shuttle-box, the bolt q, Figs. 1, 4, and 6, presses against the slide a, and by means of the latter said bolt is prevented from displacement when the shuttlebox is in correct position.

The slide in Figs. 4 and 5 is provided with openings :0 and cross-pieces orstays y. The distance from one stay center to the other corresponds exactly to the height of the box from leash to leash. When the shuttle-box n is at its proper position-that is, when the one shuttle-box bottom is precisely at the height of the run or way of the lathe-one of the cross-pieces or stays y will place itself in front of the bolt q in such a manner, according to the position of the the shuttle-box, that a displacement or shifting of the arm is prevented, because its extremity 75 will strike on a stay or bridge y.

When-the shuttle-box for any reason whatever has not reached its correct position at the backing of the shuttle, the picker or driver or cannot execute its movement in the arrow direction. As a consequence, to avoid breaking, the pivot Z of the picker-stick must be capable of displacement in the slot .2 of the guiding-arm 19. There is nothing to prevent this displacement in this case, as with the incorrect position of the box the bolt q is not located opposite one of the bridges or stays y, but opposite one of the openings to, so that, as shown in Fig. 3, the bolt can pass through these openings, whereby breaking of the beatup is prevented.

The spring 2, Figs. 1, 3, and 4, pulls back the picker-stick It as soon as the batten-levers f go back.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the shuttle-boxes of a loom and the picker-stick, of a sliding fulcrum for the picker-stick, and means controlled by the position of the boxes for holding said fulcrum against sliding when the box is in proper position.

2. The combination with the shuttle-boxes of a loom and the picker-stick, of a sliding rod or bolt suitably guided and pivotally connected with said picker-stick and forming the fulcrum therefor, and means controlled by the position of the boxes for holding said rod against movement when the box is in proper position.

3. The combination with the shuttle-boxes of a 100m and the picker-sticks, of a sliding bolt suitably guided and having a T-shaped head, a shoe at the lower end of said stick 5 pivotally engaging said T-shaped head, and

means controlled hy'the position of the boxes for holding said bolt against movement when the-box is in proper position,

4. The combination with the shuttle-looxes I 10 of a 100m, and the picker-sticks, of a sliding bolt suitably guided and having a pivoted com Witnesses EUGEN MILLER, AUGUST BEBEL.
