WEFT-REPLENISHING MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 769,865, dated. September 13, 1904.

Application filed January 3, 1903.

To all whmn it 17000; concern:

Be it known that I, CONRAD HZSMIG, mill director, a citizen of the German Empire, residing at Muhlbachstrasse 14, Pfersee, Augsburg, in the Kingdom of Bavaria, Germany, have invented a new and useful Weft-Replenishing Mechanism for Looms, of which the following is a specification.

The subject of the present invention is a contrivance fixable on looms and easily set in action by means of the weft-fork whenever a pick fails for the insertion from a carrier into the shuttles of filled bobbins while the loom is working, the weft-fork and such contrivance being arranged on the breast-beam on the same side as said carrier, through which arrangement failures in the pick occurring in consequence of the emptying of the bobbins or breaking of the thread are obviated.

In the accompanying drawings an example is shown of this contrivance as constructed.

Figure 1 is a plan with partially horizontal section of a shuttle-box of a loom at a point of time shortly before the lay finishes its forward stroke; Figs. 2 and 3, vertical sections along the lines a b and 0 d of Fig. 1, respectively; Fig. 4, a front view wherein it is assumed that the breast-beam has been partially taken away. Fig. 5 is a detail plan view of the spring 21. Fig. 6 is a detail plan view of the spring 22. Fig. 7 is a side view of view given by Fig. 5 of the spring 21. Fig. 8 is a side view of view given by Fig. 6 of the spring 22.

In a well-known way the weft-fork is fixed to swing on the slide 27 which works in a guide 28, adjusted on the breast-beam 26. The non-furcated arm 1 of the weft-fork, which lies on the hammer 3 of the weft-fork, has at its end a nose 2, against which a lever 4 can strike. This lever is fixed on one end of a shaft 6, set at the front of the lay 5. A. lever 7 is fixed on the other end of the shaft 6. The end of such lever 7 is linked into a slider or runner 8, Fig. 2, which is set slidable underneath the lay 5 on the fore part of the prop 9 and is acted upon by a spring 10, Fig. 4. On the frame 11 of the loom an angle- lever 12 and 13 is set, Figs. 3 and 4. Hinged to the one arm, 12, of such lever is a lever 14,

Serial No. 137,708. (No model.)

and hinged to the other arm, 13, of such lever is a rod 16. The lever 14 at its free end has a nose l5, behind which the nearer end of the runner 8 can be slid.

One end of the rod 16 is hinged to a slider 17, which slides up and down a bearer 18, fixed to the frame 11 of the loom and is operated upon by a spring 19. The spring 19 is fastened by its under end to an eye in the rod 16 and byits upper end to a hook at the top of the slider 17. When by the stroke of the machine the slider 17 is slid upward, then the spring 19 is extended. When such stroke is finished, the ensuing contraction of the spring pulls the slider 17 downward again. The bearer 18 is arranged at the same side of the loom as is the weft-fork. To this bearer 18 is fastened a carrier 20, which serves to hold the filled bobbins as these one after another are to be placed in the shuttle. This carrier 20 takes some thirty to forty bobbins and in such a manner that each undermost bobbin is so held by springs 21 and 22, Fig. 4, that it can be easily pressed out of the carrier. This pressing out of each undermost bobbin is effected by means of a push- frame 23 and 24, having an arm 25, by which it is attached to the slider-l7. The part 23 of the push-frame presses on the head of the undermost bobbin and the part 24 on its wound thread, Fig. 4.

The way in which this appliance works is as follows: So long as the pick goes properly and the bobbin is not emptied the weft-fork will in the well-known mode with the forward stroke of the lay so respond to the pick that its arm 1 is lifted off the hammer 3, and consequently the nose 2 on such arm 1 remains out of reach of the lever 4; but so soon as the pick fails, either through emptying of the bobbin or breaking of the thread, the arm 1 of the weft-fork stays laid on the hammer 3 of the weft-fork. In consequence shortly before the forward stroke of the lay finishes the lever 4 strikes against the nose 2 of the arm 1, and thus causes the shaft 6 to rotate. Because of such rotation of this shaft 6 the lever 7, fixed on its under end, so displaces the runner 8 that the butt-end-of said runner is laid behind the nose 15 of the lever 14. The lever 7 is therefore taken along with the lay, which is still in its forward movement, and by this means and the action of the angle- lever 12 and 13 and of the rod 16 of the slider 17whereto the push- frame 23 and 24 is attached-put into a downward motion. At the moment when the forward stroke of the lay is finished the bobbin to be removed is then in the shuttle exactly beneath the undermost bobbin of those in the carrier 20. Such undermost bobbin in said carrier is by means of the push-frame 23 and 24: pressed out of the carrier and into the shuttle. Through such pressing in of the new bobbin the old bobbin is pressed downward out of the shuttle and falls through a slit 29 in the shuttle-box of the lay into a box.

What I claim as my invention, and desire to secure by Letters Patent, is

In a weft-replenishing loom, a weft-fork having a nose or projection at its outer end; the

through failure of the filling; a runner on the lay and a second lever on the vertical shaft adapted to move the runner to operative position; a carrier for the bobbins; a push-frame and a device engaged by the runner and connected to the push-frame to transfer a bobbin from the carrier to the shuttle, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing witnesses.

CONRAD HAMIG.
