This :inventionrelates to looms for weaving pile fabrics and more part-icularly..to

Vcorresponding in general with the reeds, the

looms of thetype employing pile wiresvarranged longitudinally ofthe fabric or in the i n v separated by the rods which accordingly direction 'of the warps'.v .Y

The principalvobject Vof the invention is As clearly shown in Figsf and 4, each of the rods 18 has near the upper end flanges l19 and 21 extending transversely'frointlie 65 to vprovide improved meansfor forming the loops on the pile wires, whereby the loopforming operation is a positive one precludlio ing thel possibility of missing.

The invention vfurtherv contemplates 'the' provision of novel loop-forming means constituting amaterial' and vhighly practicable improvement over mechanisms previously used for this purpose.

Vith reference to the drawings, 1 designates the harness of a loom, 2 the lay, and 3 theV pile 4 and which have at their outer ends guides 5 for rotary cutters G. The nature ofthe cutting means may vary largely and has no partV in the present invention, In the 'present instance, the individual guides 5 are formed, as shown in Figs. 5 and 6, with a slot 7 for reception of thel edges of there; spective sockets 8 in the ends of the pilewires 3. Clamps 9 are provided on the support 11 for retaining the guides in proper position relative to cutters and pile wires.

. The other' ends of the pile wires 3 are respectively 'supported at the upper ends of upright blades 12 mounted in a frame 13 interinediate1 the harness and the lay. As shwniii Fig'. 2, this frame comprises two iigirig'hts 14, 14, aiicl two herianntal 'icse wires which pass through the reed cutters, andare adapted to fit into -man shaft QS cf the leoni through Appiicamnsizi 'Apriifia i925. serial 23,584.r

bars-15 and bars 15 and-*16 funcf' tion to support a series lfof upright yrods 18 warp threads passing between and beingGO constitute vertical guides for said threads.

the endswith a hook formation 23 which fits 75 over the' top of the bar 22T, and thelatter, as shown in Fig. 2 is provided with a series of slots 17 in which the blades are seated, andy these slots are so arranged that the blades occupy positions opposite the spaces between 80 L the rods 18. Also the cross bar 22 is voffset transversely from that side of the frame ad# jacent the harness so that only the inwardly offset and comparatively thin and flexible upper ends 24 of the blades lie between the 85 guide rods 18. As shown in Fig. 1, the upperextremities of the blades ylie opposite the flanges 19 and 21, and at a pointimmediately below the flanges each of the blades has a forwardly projecting tongue 25 over 90 which fits one end of a flat sleeve 26-in the other end of which lits the associated pile wire 3. The sleeve 26 is preferably soldered or otherwise attached to the tongue 25,',and with the guides 5 secured to the respective 95 pile wires", there is provided an easy method for withdrawing the pile wires in the event of repairs being required. After cutting the loops and releasing the clamps 9, itwill be apparent that the wires may be withdrawn L without diliiculty.

Mounted for longitudinal reciprocation on the'frame 13 below the cross bar 22 is a beam 27, and the lower recessed endsof the blade 12 lit down over this beam and extend into 105 transverse slots whereby the longitudinal reciprocatory movement of the beam results in oscillation of the blades about their fulcrums on thev bar 22. The beam is shown actuated in the present instance from tllie tie medium tif-tt the, shaft mi a. nam

lever 3l mounted for horizontal oscillation about a pivot 32 on a bracket 33, the latter gaging the cani while the other is pivotally secured at 34 to the beam 27.

In the present instance I have shown two sets of'heddles 35 and 36. The heddle-35 has two eyelets, one for the pile warp 37 and the other for the three binder warps 38; while the heddle 36 has a single eyelet for a binder warp 39. Obviously the number and character of the warp threads may .vary widely according to the nature and desired characteristics of the fabric.

The mode of operation of this type of loom is in general well known to those acquainted with the art. The heddles 35 and 36 reciprocate oppositely to form the shed for passage of the shuttle or shuttles and the lay operates in the usual fashion to beat in the wefts or filler threads deposited by the shuttle. The eyelet holding the pile warp 37 is so positioned in the heddle that on each upward stroke this warp is carried above the top of the blade 12 and pile wire 3.

In the normal extreme positions of the beam 27, determined in the present instance by the cam 29, the upper ends of the blades 12 lie against one or other of the faces of the respective rods 13 between which the individual blades lie, and when so positioned( the flange 19 or 2l, as the case may be, of

the rod 18 against whichy the blade lies guides the warp 37 in its downward movement over and past the upper end of the blade, as will be readily understood by reference to Figs. 3 and 4 vof the drawings. The positions of the blades accordingly determine on which side of the various pile wires 3 the warp 37 is brought down, and the cam may be so formed and timed that this warp is successively brought down on opposite sides of the wires. The warps 37 being tied down by the filler threads, passed over the warps and under the wires when the warps are depressed form loops over the wire, as indicated at 41. in Fig. 1, and these pass into contact with the cuttersf which sever them at the top to -form the pile.

By extending what in eect is the pile wire upwardly between the rods 18 so that they lie between the guide flanges 19 and 21, and by actuating the wires as described, it is impossible for the warp 37 to pass down the wrong side of the pile wire, and the loopforming operation is accordingly a positive one.

A considerable advantage of the construction is found in the loose mounting of the blades 12 which permits them to be lifted freely from the support. This avoids much possible breakage. It will also be noted that the flexibility of the upper ends of the support blades provide for a bearing of these parts against the warp guides without too Y` tine adjustment of the parts.

, There may be considerable Vmodification without departurefrom ,the essential fea-V turesof the inventiomand I do not wish to` ing said wire for vertically*reciprocating a pile warp said wire.

3. In a loom, the combination with a warp-wise pile wire, of meansy for elevating and depressi-ng a pile warp, means for transversely reciprocating the pile vwire at least in part to positions on opposite'sides of the path of travel of said warp, Vand relatively stationary guideV means for positively disuccessively on opposite sides of rectingrsaid warp to Vthe side of said pile wire. A 1 4. In a loom, the combinationwith spaced rods, of means for reciprocating. a pile warp between said rods,'a warp-wise pile wire extending between said rods, means for transversely reciprocating that part of the wire lying between the rods from one side of the intervening space to the other, andV transverse projections on the rods to guide the warp past the top of the pile wire.

6. In a loom, the combination of spaced vertical guide members, of means for reciprocating a pile warp between said guides, a support member oscillatory about an airis substantially parallel to the warp and having an upper thin and ilexible end extend.- ing between said guides, a warpavise pile wire attached to said upper end, and means for oscillating said support to alternately ico shift the upper end from one side of the insaid guides and havingy an vupperftbin endextendingand movable laterally therebetween,
