- This invention relates to apparatus a for selecting. andseparating warp threads injthe preparati nio'fthe'warplf r l om fe we rr. ing, and,to;that type of apparatusin which.
-; acarriageahaving .a selector with a; hook de viceat one side is @caused to, travelypa'st the warp threads while the latter 1 are suspended in: a state of E tension between top and bet tom clamping members, the selectonas it .ap-
preaches eachwarp lthread. 'engaging same with? .a. forward movement and transferring ltUWith-fi, diagonal movement on to a sep- I aratbl'balong which the selected threads are spaced in a position "for enabling them 'to be drawn through the: healds and reed by the operator. 1;
In machines of; this class it is. possible for the selector tomiss transferring a thr'eadon to the separatorrandfor suchthread to slip ofi the selector and take up a position-behind the first .few unselected. warp threads with. the-result. that if I the fault is undetected quite a vnumber 1 of-threads. may be selected, transferred on to the separator; takenofi the latter and drawn through the healdsj and reed before the missed thread is caught bythe selector: and transferred to the separator.
This causes the missed thread to occupy] a crossed position'in the warp and it is liable to produce .f-aulty weaving. .Thepresent in.-
ventionuhadfor its. chief object to overcome this :objection; to render ,the action of the.
selector morej certain and to. introduce a simple and efiicient form; of mechanism by meansof awhich the -,-tensioni on. the, warp threads can; bepea'sily 'and'accurately adjusted.
. According to thisinventionmeans vided Qwhereby any thread that 1 the: selector;
fails to transfer, tothe separator isprevented from getting behind. any of .the remaining threads so that it will again be operated upon by the; selector during; the next operative movement ofthe. latter. Themovementr -of;-ttheselector in relation to; that of the sepr arator is so timed that theselector-transfers a threadion tothe separator whilst the latter is making its forward orr spacing movement,
and commences: its return stroke before suchforward movement is completed, The bottom clamping members 1 previously,r-eferred m are-:inounted in 'such'manner that. they can be moved towards and away from a framein such manner :as to deflectthe warp threads over the iedg'e of such frame and so increase- .clamping members can be raised, or lowered h ft p. :bott

What I c aim as my invention and desire to secure by Letters Patent in the United States, is:-
1. In apparatus for selecting and se arating warp threads in which a power riven carriage containing war selecting and separating mechanism is a apted to be driven past warp threads which are maintained in a state of tension between two pairs of clamping members, the combination with a thread selector and a thread separator of means stationary on the carriage for preventing any thread that the selector fails to transfer to the separator from springing past in front of any of the remaining threads so that it will again be operated upon by the selector during the next operative movement of the latter.
2. In apparatus for selecting and separat ing warp-threads in which a power driven carriage containing warp selecting and separating mechanism is a apted to be driven past warp threads which are maintained in a state of tension between two pairs of clamping members, the combination with a thread selector and a thread separator of a thread deflecting plate stationary-mounted of the carriage containing warp selecting and separating mechanism is adapted to be driven past warp threads which are maintained 1n a state of tension between two pairs of clamping members, the combination with a thread selector and a thread separator of amine):- tending across the warpthreads and means i for moving one pair ofclamping members to a variable extent towards and away from the rail to deflect the warp threads over the edge thereof and regulate their tension, or
move them entirely clear of the rail, and means for securing the clamping members in an adjusted posit-ion.
4. n apparatus for selectingand separating warp threads in which a power riven carriage containing war selecting and separating mechanism is a apted to be driven past warp threads which are maintained in a state of tension between two pairs of clamping members, the combination with a thread selector and a thread separator of a rail extending across the warp threads, means for movin one pair of clamping members to a variab e extent towards and away from the rail to deflect the warp threads over the edge thereof and regulate their 'tension, orlmove them entirely clear of the rail, means for securing the clamping members in any adjusted position, and screw actuated adjusting mechanism for moving either end of the said pair of clamping members independently.
