THACKER andCHRisTAPHER C. GosNELi., citi- -provide a simple, practical and comparatively..inexpensive adjustable warp stop motion-drop wire rack for looms equipped with a center support and adapted to be readily lifted from a loom with the pattern-to bel retied, and capable ofeffectually preventing the drop wires or devices from becoming tangled and of enabling the same to be easily and quickly tied. i.

A further'object of the invention isl to profvide a drop wire rack of this character adapted to materially lessen the expense of operating looms and capable ofincreasing the output ofthe same and adapted also to *not only save patterns for warp tying machines but-to also be used to great advantage in drawing new styles or patterns of goods.

It is also an object of the invention to 'provide a warp stop motion drop wire rack 'with which it .will be impossible for the v varn to come'in contactL with the bottoms of the drop wires or "drop devices and thereb v prevent suchdevicesfrom becoming misplaced or tangled. Y

With vthese andother objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described.v illustrated in'thc accompanying drawings, and pointed outin. the claims hereto appended: itjbeing understood that various changes in the formaproportion. size and minor details ot' construction. within the scope of the claims, may be resorted toy withou't departing from thespirit orsacriiicing any of the advantages of the invention.

In the accompanying drawings in'wh-ich is illustrated-the`preferred embodiment of the invention, the' adjustable warp stop mo- "tion drop wire rack comprises in its construction vertical end plates 2 and lower horizontal connecting bars and a pair of lower horizontal rods 4. The lower longitudinally disposed connecting members or bars 3 consist of `flat bars having their side faces arranged in vertical lanes and in a t n a parallelism and securedin openings 5 and recesses 6 of the' endplates by transverse fastening devices 7. The lower bars 3 over which the yarn passes are located at a point intermediate ofthe upper and lower ends of theend plates and the openings 5 which receive the center longitudinal bar are located.

end plates. The end planes which are permanently secured totheends ofthe longitudinal bars 3 are providedabove the same,V with perforations `8 arranged in p'airs and to receive upper and lower longitudinal rods, the lower rod 4 extending through the upper' slot l() of the drop wirsor drop devices 11 and thenpper rod l2 being adapted to be passed through theupper slot for support- 106.

ing the drop wires in an' elevated position when the rack 1s to be removed from a loom for enabling the drop wire devices to be' tied in position for preserving'the pattern and for enabling the drop wire devices and, 105

the rack to be replaced in the loom when it is desired to use the pattern again. Byl this construction the drop wires or drop devices are.' prevented from becoming misplaced or entangled and a material saving-in the ex-` 110 pense of operating looms is effected and the output is increased. The end plates are provided at the side edges with set screws or clamping screws 13 for detachably engaging the ends of the upper and lower rods for securing the same in position. The end plates are shown equipped with supple mental plates 14: riveted or otherwise secured to the inner faces of the end plates and extended above the same and provided with perforations 15 for the reception of horizon* tal rods in the adjustment of the same but instead of providing supplemental plates the length of the end plates may be readily increased to vsecure the desired range of adjustment as will be readily understood.

Then the rack is in position in a loom, it is supported in the center by a central support 16 designed to be permanently mounted upon the loom frame consisting of a standard or stem 17 provided at its upper end with a horizontally disposed arm 18 and supporting a lower horizontally extending arm 19 arranged in parallelism with the upf per arm 1S. The support 16 may be fastened to the loom frame by any suitable fastening devices andthe drop wire rack may be detachably supported upon the loom frame in any desired manner.

The upper arm 18 is provided in its lupper 3 edges with notches or recesses 20 to receive the lower rod of the rack and the lower arm which has an attaching portion or fiange E21,`

is provided in its upper edge with rectangular recesses 22 located at the central and terminal portions of the arm 1) and arranged to receive the lower longitudinal bars. The

'fiange 21 is riveted or otherwise secured to the stern or standard of the central support and the said stem or standard is provided at its lower portion with a perforation 23 for the reception of a suitable fastening device ior mounting it in position on a loom.

The warp threads not shown pass through the lower slot and support the drop wires or drop devices in an elevated vposition and these drop wires or drop devices which constitute detectors are adapted to fall when one of the warp threads break and arrest the reciprocation of the members with which they coact and thereby efl'ect a stopping of the loom in the usual manner. The drop wires or drop devices extend downwardly y between the intermediate and side longitudinal bars 5 and 6 which support the yarn so that there is no liability of the yarn coming in contact with 'the lower end of the drop wires or drop devices and displacing the same.

The yarn passes over the lower longitudinal bars and under the lower rod and when it is desired to remove the rack from the loom the upper rods are placed in position through the upper slots of'the drop wires or drop devices which are thereby supported in such elevated position that they occupy when in use or operation and they may be easily and conveniently tied in such posi tion so that the design or pattern can be preserved for instant reuse. rl`his will greatly lessen the cost of tying up patterns and will enable the saine to be arranged for use in a loom with much less time than has heretofore been possible thereby saving both the expense of handling such devices and also increasing the output of the loom. In fact in a mill oi' five thousand two hundred and sixty-four spindles and twelve hundred and eighty-eight looms it has effected a saving of $10.00 a day in actual labor and has increased the production The tangling of the drop wires or drop devices has resulted in more trouble than anything else encountered in the operation of a loom and the elimination of this trouble will greatly facilitate the operation of looms. Furthermore, the rack not only contributes to the preserving of the pattern in use on a loom but greatly facilitates the making of new patterns owing to the supporting oit' the drop wires or drop devices by the top rod. Also the central support of the rack permits the latter to be easily lifted oit of it in removing the rack from a loom.

1. A warp stop'motion drop wire rack adapted to be placed on and removed from a loom bodily and including fixed lower rods adapted to pass through the upper slot of the drop wires and supporting means carried by the rack and cooperating withthe fixed rods to hold the drop wires against vertical movement for holding the ldrop wires in an elevated position and for en abling the pattern to be tied with the drop wires in such position.

2.
