TERRY LOOM.

Application filed February 17, 1923. Serial No. 619,585

To all whom it may concern:

Be it known that we, WILLIAM DORIETY and (interns MAOARTHUR, citizens of the United States, residing at Paterson, lnthe county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Terry Looms, of whlch the following is a specification. v

This invention relates to those looms for weaving terry fabrics in which the reed s pressed backward in the batten for a suitable number of picks, during which the terry warp is floated, and then, the terry warp being again bound in by the weft, the reed is returned to its normal position so that the first time it beatsup thereafter it sl des the intervening weft forward on the main warp and thereby packs it up to the cloth and 1ncidentally causes the floated warps to assume the form of loops, it being understood that for this latter purpose the terry warp beamrotatively yields independently of the main warp beam.

One object a terry loom having a simple, inexpensive and reliable combination of parts whereby an endless variety. of designs or patterns may bewoven. nother object 1s to make it possible, by changes readlly effected, to apply a terry motion-to any ordlnary loom.

In the drawings,

Fig. 1 is a vertical sectional view of a loom embodying the present invention taken on line 1--1, Fig. 2;

Fig. 2 is a sectional front elevation of the left-hand end-portion thereof;

Fig. 3 is a plan of the forward portion Figs. 4c and 5 are vertical sect onal views through the batten and reed-structure, showing the means for controlling the latter in its two main positions Fig. 6 is a plan of certain parts of said means, the batten appearing in horizontal section; and p p Fig. 7 is a front elevationof certain parts appearingin Fig. 6.

The loom frame a, its breast beam b,the lay swords c upstanding from and secured to the rock shaft 03, the lay or batten e carried by the lay swords, the crank shaft 7 with the cranks of which the batten-1ncluding structure d, 0, e is connected by the pitman g, and the cam shaft h are or may be all the same as in any ordinary loom. On the loom frame is arranged a pattern of this invention is to provide mechanism, here in the form of anyordi nary dobby and used to manipulate the har ness' (not shown) ofthe loom. The dobby consists of a frame 2' in which are fulorumed jacks j to which the harness cords are adapt: ed to be attached, A: being levers pivoted to the jacks and having upper and lower.

pivoted hooks Z adapted to be caught and pulled outward, to move the jacks outward, by the upper and lower knives m which are caused by suitable means of well knownconstruction and not shown to reciprocate in opposite directions; and n are the lifting wires for the respective hooksl adapted to be raised'by the levers 0 which are made,

to rise and. fall by the pins p of a pattern chain Q which extends over a cylinder 1' that is rotated step by step by any suitable means (not shown),

The reed structure includes the reed s, the upperandlower horizontal bars 25 uin which the reed is setand end brackets 4; connecting these bars. The lay swords have attached to them brackets to affording pivots at m (Figs. 3, 4 and 5) for the reed struc:

ture, the pivots being actually engaged in holes in the end brackets 12. The reed may swing backwards on its pivots subject to the pressure of spring plungers y arranged in suitable housings a on the lay swords.

Bolted to the back of the bar a at each end of the reed structure is a fitting 2 in which ispivoted to move up and down a latch in the form of a hook 3 which projects through a slot 4 in the batten and whose shoulder 3 when the reed structure is fully forward, may abut a wear plate 5 set in the front of the batten and slotted to receive the hook. This wear plate is secured to the front of the batten by a screw 6 and also by a lag screw 7 which has a long rearward extenslon 8 received by a horizontal hole 9 in the bar a of the reed structure, which hole is elongated transversely of itself and vertically lateral lost motion of the reed structure otherwise possible at the pivots 00 is prevented by the extensions 8 of the lag screws 7 At the under side of the batten are secured two brackets 10 in whichis arranged a rock shaft 11 having two levers l2 fixed thereon. At their forward ends these levers have pivoted thereto upstanding push rods 13 which are guided in holes in a ledge 5 proiecting from the wear plate and each of which has a rounded head 13* on which the s' norm breast been ere p nding hee s 3 t s Th end f h hook is 'tqrnied with a notch To the rear end of one of the levers 12 is pivoted a rod 14 which depends from the lever. The lower end of the rod 14. is connected with a lever 15 fulcrumed in a bracket It;

In this way the terry, or looping of the terry warps, produced, the loops being developed when, after each period when the reed structure is pressed back, the loom, starts to operate for a time with the reed structure held for ward," Ordinarily, as explained, the fabric from start to finish would be siniple or plain terry (i. e., involving in alternation and t rough t he aving cert n umbe of picks when floating of terry warp occurs and 3 6 7mm number (if picks when binding in of the terry warp with the main warp occurs), By our invention this terry weaving can becarried on for any selected extent lengthwise of the fabric (the reed structure being alternately pressed back and then held forward, for nnn ber of picks desired to torinthe loops and bind in the terry warp with the main warp), and then plain weav ing can ensue for any desired extent lengthwise of the fabric, the reed being left held forward by the hooks atsuch times. Thus a pattern will be, developed in the'hfabric in which there will be lQQPQCl 0,1 terry portions extending across the fabric and of any desired width and intervening plain-weave portions of any desired width. Many variations otthis are possible especially when groups of the warpsat intervals are all of then retained as parts of the main warp, that is, are wonnd on the main warp, beain nd so a e not ubj c te h loop n t n. e e y i r s is t fa ric s a erna y formed terry weave and plain-weave, rec tangular terryligures will be produced.
