NEEDLE-LOO1VL Application filed December 16, 1919.

T 0 all whom/15 may concern Be it known that I, HENRY R. PARKER, a citizen of the United States, residing at Norristovvn, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Needle- Looms, of Which the following is a specification.

My invention relates to looms, and particularly to improved shed-forming mechanism therefor and provision for employing` core threads in connection with the Warps, as hereinafter' fully described in connection with the accompanying drawings, the novel features beingI specificallyu pointed out in intel alalirns.

any desired number of xedly extending core threads 23.

All ot' these Warp thread guide rods, as shoyvn, are conveniently supported upon two horizontal pivotally swung cross bars 25, 25a, upon which they rest by gravity, and which engage respectively the ears 16 of each rod 15, and the ears 18 of each rod 17; each of said bars having radius arms 26, 26 pivotally mounted on the loom table at 27 and 27a re'- spectively, and having' periodic swinging movements imparted thereto in like arcs 28 or 28a, to thron7 their guide eye portions alternately to opposite sides of the table aperture 5 for ormingthe sheds.

23 in connection with the forked prongs 5V of the needle 8, permit thev introduction of reinforcing Warps to strengthen the fabric,

' While the double Wert introduced covers and locks the core threads Within the fabric.

The reciprocating` rods 15 and 17 operated by the bars 25 and 25, which latter' swing in the arcs 28 and 28a, cause the guide eyes 10 of each reciprocated bar to travel in anV arc of equal radius with the arcs 28 and 28a, so that the Warp threads 3 and guided therein swing in a radius .ii-om the Weaving point above the opening 5y and prevent any see-sawing movement of the threads in the guide eyes. This freedom of reverse movements in the guide eyes 10 eliminates Wear upon the threads and permits increased speed of the machine With safety. The rods 21 may be independently supported ii' desired, above the bars Q5 and 252L so that even the slio'ht risino' and allinO movement im-V b b t3 parted to them may be eliminated.

' Uy improved construction is simple and effective and reduces unnecessary wear on the warp threads, and the forked weft needle permits of satisfactory introduction of reinforcing core threads When desired.4

lVhat I claim is:

1. In a loom, a shed forming mechanism comprising Warp thread guide rods all arranged in one plane and in parallel relation7 with alternate ones grouped together in separate series, and reversely movable carrying devices each of which is operatively connected to one series of rods and slidably supports th'e other series.

2. In a loom, a shed forming mechanism comprising Warp thread guide rods all arranged in one plane and in parallel relation,

-With alternate ones grouped together in separate series, carrying bars respectively connected to one series of rods and slidably supporting the other series, and means for reversely moving said bars.

3. In a loom, a shed forming mechanism comprising Warp thread guiderrods all are ranged in one plane and in parallel relation7 With alternate ones grouped together in separate series7 pivotally mounted carrying bars forthe respective series, andl means for reversely moving said bars in equal arcs.

4. In a loom, a shed forming mechanism comprising Warp thread guide rods Vall arranged in oneplane and in parallel relation, with alternate ones grouped together in separate series, and intervening fixed corethread guides, and reversely movable carrying devices each of which is operatively con-- nected to one series of rods and slidablyl supports the other series,l and said devices jointly slidably supporting the core-thread guides. Y

5. In a loom, a series of vvWarp thread guide rods comprising oppositely movable groups adapted to forin-l opposing shed- Walls, intervening iXedcore-thread guides, reversely operated devices engaging the respective movable rod groups to forni the sheds, a movable weft-thread needlehaving a forked'body adaptedy to straddle the core threads and With forked prong ends, and a reciprocatively operated salvage hre-ad shuttle. V

6. In a loom, a vertical shed forming mechanism, comprising reversely movable horizontal guide rod supporting bars, warpthread Vguide rods resting 0n said bars and arranged with alternate ones grouped together in separate series, 'operative connec-v tions from each series to' one of said bars, and means to reversely move said bars.

In testimony whereof I aflix my signature. y.

HENRY PARKER.
