LOOM FOR MAKING STRAW MATTING.

SPEGIFIGATION romingpaa of Letters Batent No. 693,091, dated February 1 1, 1902.

Application filed November 19, 1901. Serial No. 82,869. (No model.)

To all whom it may concern: I

Be it known that I,WILLIAM WATTIE, a citizen of the United States, residing-at Worcester, in the county of Worcester and State of Massacl1u'setts,haveinventedcertain newand useful Improvements in Looms for Making Straw Matting, of which the following is a specification. I

My invention relates to looms for making straw matting and similar fabrics, and more particularly to improvements in the mechanism for making the selvage edges on straw matting of the description set out in my application for Letters Patent of the United :5 States, filedJanuary19,1901,SerialNo.43,939,

to which reference is hereby made.

The object of my invention is to provide. mechanism for making the selvage' edges on the straw matting above referred to; and my invention consists in certainnovel features of construction of my improvements, as will be hereinafter fully described.

I have only shown in the drawings sufficient portions of a 10011], with my improve- 2 5 ments applied thereto, to enable those skilled in the art to which my invention belongs to 'make and use the same. V I

Referringto the drawings, Figure 1 is a rear perspective view of parts of a loom and the mechanism for making the selvage edges on the straw matting applied thereto. Fig. 2 is a rear view of some of the parts shown in Fig. 1, showing a difiere'nt position of the parts, looking in the direction-of arrow 0.,Fig. 3. Fig. 3 is an end view of the parts shown in Fig. 2 looking in the direction of, arrow b,

same figure. Fig. 4 is a front view of the stand and the guides for the selvage-cord and the' supplemental warp or binder thread.

Fig. 5 is arear'view of the stand shown in secured the lay 5, above which extend the horns 2 for the hand-rail. (Not shown.) The bottom shaft 6 is mounted in bearings 7 on the loom side 1. The crank-shaft 8 is mounted in bearings 9 on the loom side 1 and connected by crank -connector 10 with the lay 5. V

I will now describe the mechanism shown in the drawings for making the selvage edges on the straw matting.

It will be understood that the mechanism is in duplicate, one mechanism at each end of the lay. It will only be necessary to describe one mechanism.

A plate 11, having a central opening of the shape shown in Fig. 5, is attached at its lower bent end 11" to the upper side of the lay in such a position that the vertical plane of said plate is close to and in alinement with the reed. (Not shown.) In connection with the plate 11 a second plate 12 is used, which has two longitudinal guide-slots 12 12 therein and which is attached at its npperend to the upper end of the plate 11 by bolts and nuts, the

bolts extending through elongated slots in the upper end of the plate 12, as shown in- Fig. 4, so that the plate 12 may be adjusted up or down, if desired. The lower part of the plate 12 extends inwardly, so that it will extend-within the opening in the plate 11 and be in alinement'with said plate. \Vhenthe plates 11 and 12 are secured together, as shown in Fig. 4, there are the two vertical guide-slots 12' 12' and also the U-shaped guide-slot 11' extendingaround the plate 12. Theplates 11 and 12 maybe made inone piece; but I prefer to make them in two pieces for adjustment. The upper end of the needle 13 extends loosely through a vertical opening in the lay.

--The lower end of the needle 13 is pivoted to.

a vertically-moving rod 14, mounted and having its bearing in a bracket 15, secured to the lay-sword. The lower end of the rod 14 extends through a collar 16 and is adjustable thereinby a set-screw 16. The collar16 has a stud 16 extending out from one side thereof, whichstud extends through an ear orex tension 17 on the collar.17, secured oy a setscrew 17 on the upper end-of the rod 18, the

preferably bent upwardly, as shown, to exd. in the path of and be, engaged by theiph'ery'of-the double cam' 22, fast on the ottomshaft 6, as shown. A-spring 23, cm!- -nected-'at one end to the end 20 of the arm ,andat-its other end to a rod 2=t,'ex tendihgbetween'the loom sides, acts to hold the nd=20 'ofthe arm 20 in engagement with the cam 22.. The vertical motion of the needle 13-as the 'lay moves is caused by thecarn 22 through the intermediate mechanism above described.

g '1 will no'w'd'escribethe means for communicatingan oscillating motion to the needle .eyat its; upper end from right to left and i'ei't toright. ,Aguide-fork 25 loosely incloses the upper end .ofthe'needle 13 on three sides and is secured at its end to aside extension.

26 on the lever 26,.centrally pivoted at 27 on the lay-sword 2. The lower endof the'lever has an elongated 'verticalslot26 therein, ji-ntowhich extends one end of a lever 28, cenrally pivoted on a stud '29 on a bracket or stand 30, secured to the lo'omside. The other end of the lever- 28 has a roll- 31 thereon, which extends in the path of and is adapted I to. be engaged by the face of 'the cam 32, in

'}this instance semicircular in shape and fast on the bottom shaft 6. The cam 32 has the ailat circular surface to engage the roll 31 and the inclined or angular extensions 32'. Ispring 33 is attachedat'one end to the upper inner edge of thelever 26, and in this in- .intstan'e the other end of the spring33 is connected by a rod 34 to the upper end of the duplicate lever 26 on the opposite side of the iborn. The action of the-spring 33 is to keep f f theroll 31 on each lever 28 in engagement Q {s5 with .its cam 32.

then'the other-.in making the fselvage edge- 'on the matting. A stop 35, secured at the back side of the lay by a'bolt 36,.1imits the inward rockingmotion of the lever 26. .TAs'above stated, the parts above described are-in duplicate--that is, there is a needle for the turn-overthread at each end of thelay andflseparate mechanism. for' operating each needle."'

y, I will now the describe the operation of the -mechanism shown in the drawings and above described for making. the selvage edges on the straw-matting.

v The cam 32 shown at the might in Fig. 6 is in a reverse position on the 1 It will be understood that the means for in-. sertihg the individual straws between the "sheds of the warp-threads may, befof any. nsual construction,- and therefore. are-not eeaoer shown; neither is the shed-forming mechanism shown, which may be of any usual or wellknown construction.

The selvage-cord 37 extends through the outer vertical guide-slot 12 in the plate 12, and the supplemental warp-threads 38 extend through the inner vertical guide-slot, 12" in the plate 12. The turn-over thread 39 extends through an eye or opening in the upper end of the needle 13 and through the U-shaped guide-slot 11" around the outside of the plate .12. ,It will be understood that the large end of each straw is inserted first from opposite sides of the loom alternately and that these large ends which extend beyond the selvage edges. are trimmed off. The large endof the straw (not shown) is fed in in the direction of arrow (1, Fig. 1, under the turn-over thread 39, which is support-ed in the upper" end of the needle 13-and extends through the'upper part of the U shaped guide'slot 11, as shown 'in Fig. 2, and over the se'lvage-cord 37 and under the supplemental warp or hinder threads (not shown) when the shed is open. The-smaller end of the straw'(uot shown) is left extending beyond the selvage-cord- 37;

--the same time th'e'cam 32 operates, through intermediate mechanism, to move the needle 13 sidewise and carry the turn-over thread 39, ,extending through the eye of said needle and guided in the U -shaped slot 11, to the oppositeside of said U-shaped guide-slot 11 upon the inner sideof the plate 12 to bend down the projecting small end of the straw and .carry it around the selvage-cord 37 and bring it up to extend under and bear against the supplemental warp or binderthread 38 andtheadjoiningwarp-thread. (Notshown) The shed is .now' closed, as the reed has reachedthe fell of the matting. On the fol lowing pick and while the turn-over thread 39' is still in the upper-inner end of the U- shaped guide-slot 11'. a filling-straw from the opposite side of the lay is inserted-and passes under the turn-over thread 39 and binds the same into the body of the matting on the beating up of the lay. The needle 13, carrying the turn-over thread-39, is then returned 'lj'p art of the U :shaped slot'll downward' and thread 38 and'between the two sets ofwarp- I IIO ' threads.

under. the selvage-cord 37 and the supple pick to its first position. The turn-over thread 39 is always at the top of the outer or inner part of the slot 11 when the shed is open and forms a part of the upper system of warp- The motion of the needle 13 and the turn-over thread 39 is duplicated, but in the reverse order, to form the selvage on the opposite side of the matting. It will be understood that the details of construction of my improvements shown in the drawings and above described may be varied, iidesired.

My improvements may be adapted to weave fabrics other thanstraw matting, if desired. Having thus described my invention, what I claim as new, and desiretosecure by Letters Patent, is v l 1. Mechanism for making a selvage edge on straw matting, &c., consisting of a needle for holding the turn-over thread, which thread engages and turns in the projecting small end of the filling-straw, means for guiding said thread, and means for guiding the selvagee cord and a supplemental binder-thread adjoining said cord, and means for operating said needle, to move it downwardly, inwardly, and upwardly, and downwardly, outwardly,

and upwardly, substantially as shown and described.

2. In mechanism for making a selvage edge on strawmattin'g, &c;, a needle which holds the turn-over thread, which thread engages and turns in the projecting small end of the filling-straw, a guide through which said thread extends, a guide for the selvage-cord and a supplemental binder-thread adjoining said cord, and means for operating the neeinwardly,and upwardly, and. turn in the small end of the filling-straw and bring it upon the under surface of the. matting, substantially as shown and described.

3. In mechanism for making a selvage edge on straw matting, 650., a needie for holding the turn-over thread, which thread engages and turns in the projecting small end of the d1e,to carry the tu rn-over th read downwardly,

for the selvage-cord and for a supplemental Y
