MECHANISM FOR PREVENTING THE ENTANGLING OF WEFT.

Specification of Letters Patent.

Patented July 30,1907.

Application filed February 25, 1907. Serial No. 359.085.

To all whom it may concern:

Be it known that we, ROBERT MYERs and STEPHEN MYERs, subjects of the King of Great Britain and Ireland, residing at Yeadon, near Leeds, in the county of York, England, have invented a new and useful Mechanism for Preventing the Entangling of Weft-Threads in Looms, of which the following is a specification.

The object of this invention is to produce an improved mechanism in drop box looms, for preventing the different weft threads, that lie between the shuttle boxes and the warp in a loom, from becoming entangled one with another, and being carried into the warp, and ca sing trailings in in the woven cloth.

In the weaving of cloth in this class of loom, the on tangling of the weft threads one with another, from various causes, is frequent, and it is a source of much trouble and damage in the woven material, with a loss of time and extra cost in the production of the cloth.

Description of drawings. Figure 1 shows front view of part of loom with our invention applied. Fig. 2 is an enlarged plan of bracket and slide with levers. Fig. 3 is a sectional side elevation of beam and slay with dummy threads, warp threads, and operating nee dles. Fig. 4 is a plan of Fig. 3. Fig. 5 shows slight modification of bracket carrying slide and levers by which the slide is dispensed with and the pin is made to slide.

In carrying out this invention (the mechanism of which is described and shown as applied to one end of a four-box loom, but which in use is applied to each end of the loom between the shuttle box and the warp) a bracket A is bolted to the inner face of and at right angles to the bottom rail B of the loom. To the reverse end of this bracket, a flat plate 0 is bolted, its face being opposite to and parallel with the bottom rail of the loom. Upon the upright brackets D bolted to this flat plate, a sliding bar E is placed, and in a required position on the sliding bar, three angle levers F F F are pivoted by their fulcrums, the lower arms of these levers being in a horizontal, and the upper arms in a vertical position, when the loom is at rest.

I is a tilting pin, and R are stop pins.

To the end of the sliding bar E nearest the shuttle boxes, an adjustable bar G is pinned, the reverse end of this bar being pivoted to one end of an L-lever H, and to the reverse end of this lever a connecting rod J is fixed at right angles to it, and connected to a pin upon the box rod K of the loom.

To the back of the flat plate C above referred to, a vertical bar M is bolted, and in the upper part of this bar are carried three eyeleted sliding needles N, N, N, the bottom end of each needle being pivotally connected to the corresponding arm of each of the angle tilting levers, which are pivoted to the sliding bar E, the upper parts of the needles N, with their eyes, being above the top of the vertical bar M, there is also a fixed frame S with eyelets for the dummy threads. Also a thread T is preferably taken from the edge of the warp and passed through the eye of the first needle, on to the hook of the front beam, through the second needle, and back over the back beam, and through the third needle, between the dummy threads V its end being fastened to the second hook on the front beam. The threads V fixed as "dummy threads each pass from the hooks on the front rail through the eyelets in the fixed frame S, and over and around the back rest, and are joined together each forming one continuous thread, to assist in putting a br. ke or tension on the weft threads. The separate 'weft threads U are arranged to pass under the different warp threads T and over the dummy warp threads V.

When the boxes drop, the slide is pulled and the lovers F as they come in contact with the pin P are tilted over, pulling down the warp threads T and braking or putting tension on the weft threads U between them and the fixed or dummy threads V, and so prevent the entanglement of the Weft.

In Fig. 5, the tilting pin P is made to slide in the slot W, operated by suitable mechanism, and so tilts the levers in a similar manner as before described.

We do not confine ourselves to making this improved mechanism to any particular number of shuttle boxes, as by adding extra angle lovers to the sliding bar, and extra needles with their dummy or equivalent threads, corresponding to the additional shuttles, as many shuttle weft threads as are working in the loom can be effectively kept apart, and the entangling of them prevented, and the risk of damages to the cloth obviated.

We claim:

1.. 'lhe combination, with dummy warp threads, of a sta tionary guide provided with eyelets for some of the said dummy warp threads, slidable needles provided with eyelets Which engage with the remainder of the said dummy warp threads. and means for sliding the said needles to depress the first named dummy warp threads.

2. The combination, with dummy warp threads, of a stationary guide provided with eyelets for some of the said dummy warp threads, slidable needles provided with eye lots which engage with the remainder of the said dummy warp threads, a guide, a bar slidahle in the said guide, angledevers pivoted to the said bar and connected to the said needles, a shuttle box rod, intermediate driving mechanism operatively connecting the said bar with the said rod, and a pin on the said guide for tilting the said levers when pressed against them.
