NEEDLE-LOOM FOR WEAVING NARROW-WARE FABRICS.

SPECIFICATION forming part of Letters Patent No. 741,279, dated October 13, 1903.

Application filed June 6, 1903. Serial No. 1601294. (No model.)

T at whom it may concern.-

Be itknown that I, EPPA H. RYON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusettahave invented certain new and useful Improvements in Needle-Looms for Weaving Narrow-Ware Fabrics, of which the The object of my invention is to provide a needle mechanism in the class of looms referred to of improved construction for weaving narrow-ware fabrics or ribbons of considerable width-for instance,up to six inches. In my improved needle mechanism the needle has a pivotal or swinging motion to carry the filling-thread over the shuttle, supplying the selvage thread, and also an additional motion in the direction of the width of the fabric to move the pivotal support of the needle toward and away from the fabric in the operation of weaving.

My invention consists in certain novel features of construction of my improvements, as will be hereinafter fully described.

, Referring to the drawings, Figure 1 is a detached plan view of a portion of the lay and the breast-beam of a narrow-Ware loom with my improvements in needle mechanism applied thereto. The lay is shown in its forward position. Fig. 2 corresponds to Fig. 1, but shows the lay in its rear position and the parts of the needle mechanism in the opposite position. Fig. 3 is a section on line 3 3, Fig. 1, looking in the direction of arrow a, same figure, showing the hand-rail which is not shown in Fig. 1. Fig. 1 is a section on line 4 4., Fig. 2, looking in the direction of arrow 1), same figure, showing the hand rail which is not shown in Fig. 2. Fig. 5 is, on an enlarged scale, a detached front view of the needle mechanism. Fig. 6 shows a modified construction of the needle mechanism.

In the accompanying drawings, 1. is the end 1 frame of aloom. 2 is the breast-beam. 3 is the lay; 3, the lay-sword; 3", the hand-rail; 4, the reed; 5, the warp threads; 5', the complete woven fabric, which passes overa roll 6, mounted in bearings 7, in this instancesecured upon the top of the breast-beam 2.

I willnow describe my improvements in the needle mechanism.

On brackets 8, secured to the loom-frame 1, is secured a plate 9, havinga cam-groove 9' therein, in which travels a roll 10 on a stud 11 on alever 11. The lever 11 is fast in this instance at one end on a pivot-stud 1i2,which has a bearing 13 in a bracket or stand 13, secured to the rear side of the lay 3, at the outer end thereof. (See Figs. 3 and 4.) The outer end of the lever 11 has an elongated slot 11 therein,intowhichextendsapin1 1. Saidpin 14. extends up from and is secured to a bar 14, which has bearings and is adapted to have a reciprocating longitudinal motion in stands 15, secured to the front of the lay at its upper edge. (See Figs. 3 and 4:.) Secured to the bar' 14 is a plate or block 16, carrying a stud 17, on which isv pivotally mounted the hub 18 of a swivel angle-lever 18. A needle 19 is secured at one end to one arm of the angle-lever 18, and a roll 20 is mounted on a pin 20 in the other arm of the angle-lever 18 and adapted to engage and travel on the cam 21, suitably shaped and secured on the upper surface of the lay 3. A spiral spring 22, secured to the block 16 and to the angle-lever18, acts to hold the roll 20 in engagement with the cam 21. A light spiral tension-spring 23 is attached at one end to a wire 24., secured to the block 16, and has an eye 23' at its other end, through which passes loosely the fillingthread 25. The filling-thread 25 comes from a spool (not shown) and passes through an ear 16on the block 16, and then through the eye 23 and through a second ear 16 on the block 16, and then through an ear 18 on the hub 18' of the angle-lever 18 (see Fig. 5) to the free end of the needle 19 and through an opening in said needle, and then through a second and third opening at the extreme end of the needle (which end is bent upwardly, as shown in Fig. 5) and through the shed. The

shuttle 26 is mounted in the shuttle-holder 27, adjustably secured at one end on the upper inner end of the arm 28, pivoted on a stud 30 on a stand 30 on the breast-beam 2. The arm 28 has a projection 28 thereon beyond its pivot-point, which bears against a projection 28 on the stand 30. A leaf-spring 29 is secured (in this instance by a screw 29) to the outer edge of the arm 28 and bears at its free end against the projection 28". The spring 29 acts to move the arm 28 at its free end toward the fabric, as shown in Fig. 2, to slacken the filling-thread 25. The arm 28 has at its free end a downward extension 28 (see Figs. 3 and 4) and a curved arm 28, extending inwardly therefrom and in the path of a roll 31 on a stud 32 on a plate 33, fast on the top of the lay 3, contiguous to the edge of the warp-threads 5, so that as the lay moves forward the roll 31 will engage the arm 28 and move the arm 28 away from the fabric against the action of the spring 29, as shown in Fig. 1, to tighten the filling-thread 25.

In Fig. 6 is shown a modified construction of the needle mechanism. In saidfigure the oscillating needle 19 has a positive motion in both directions. The lever 18, corresponding to the lever 18 in the other figures of the drawings, has an extended slotted arm 18 into which extends and travels a pin or stud 34 on a stand 35, fast to the front side of the lay. The reciprocating longitudinal motion of the bar 14 and the block 16 thereon, through the engagement of the slotted arm 18 with the pin 34, will communicate a positive swinging or oscillating motion to the arm 18 and the needle 19to move it from the position shown in full lines, Fig. 6, to the position shown in broken lines, and vice versa. By this construction the cam 21 on the lay and the spring 22 are dispensed with.

From the above description, in connection with the drawings, the operation of my improvements in needle mechanism will be readily understood by those skilled in the art.

Supposing the lay to be in its forward position, as shown in Fig. 1, as the lay moves backward the roll 10, traveling in the camgroove 9, communicates through arm 11 a longitudinal motion to the bar 14 in the direction of arrow 0, Fig. 1. The block 16 on the bar 14, carrying the pivoted angle-lever 18, with the needle 19 attached thereto, moves with the bar 1 1 and causes the roll 20 to travel on the cam 21 and oscillates the angle-lever 18 to move the free end of the needle 19, carrying the filling-thread 25, into the shed and at the same time to move the pivoted end of the needle toward the fabric, so that when the lay has reached its rear position, as shown in Fig. 2, the free end of the needle 19 will have been inserted through the shed, carrying the filling-thread around the shuttle 26, and at the same time the angle-lever 18 or oscillating needle-support will have been moved up to the edge of the fabric, as shown. When the lay is in its forward position, as

shown in Fig. 1, the roll 31 will be in engagement with the curved portion 28 of the supporting-arm 28 and acts to move said arm slightly outwardly or away from the fabric against the action of the spring 29 to tighten the filling-thread and form a proper selvage, as shown in Fig. 1. As the lay moves back from the breast-beam the rol121 becomesdisengaged from the curved arm 28 and allows the spring 29 to act to move in said arm 28 and with it the shuttle-support 27 and shuttle 26, as shown in Fig. 2.

I have shown in the drawings only one needle mechanism for weaving one narrow-ware fabric or ribbon; but it will be understood that there are a series of these needle mechanisms on the loom, said needle mechanisms being independent of each other, to weave the fabric, except that the reciprocating bar 14 is connected with each of the oscillating needle mechanisms to operate simultaneously all of the needles.

It will be understood that the details of construction of my improvements may be varied,

if desired.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is
