NEEDLE-LOOM.

SPECIFICATION forming part of Letters Patent No. 743,107, dated November 3, 1903.

Application filed July 17, 1902.

To whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Needle-Looms, of which the following is a specification.

My invention relates to needle-looms for weaving narrow-ware fabrics, such as ribbons. In this class of looms a series of narrow-ware fabrics or ribbons are woven on one loom, each fabric being woven separately by a separate needle mechanism.

The object of my invention is to improve upon the construction of the needle mechanism for weaving said fabric as now ordinarily made, and more particularly to have each needle mechanism independently operated on the forward and backward beat of the lay.

The mechanism for operating the needle to move it in and out of the shed is located on the lay and moves with the lay. The pivotal point of the needle is so located that at the forward beat of the lay to the fell of the fabric the reed is in substantially the same line or plane as the pivotal support of the needle.

In my improvements 1 provide a spring blade or guide through the free'endof which the thread passes before passing to the needle. I also provide a needle with a turned-up free end or point through which the filling-thread passes.

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

I have shown in the drawings only one needle mechanism; but it will be understood that there is a series of these needle mechanisms extending across the loom in the direction of the width of the loom and that each needle mechanism is independent of the other 1 Serial 110.115.921- [lfTo model.)

tion from that shown in Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1, looking in the direction of arrow at, same figure. Fig. 4 is a section on line 4 4:, Fig. 2, looking in the direction of arrow 1), same figure. Fig. 5 corresponds to Fig. l, but shows a modified construction of my mechanism. Fig. 6 is a plan view of the shuttle-holderdetached. Fig. 7 is a side view of the shuttle-holder and shut tle therein looking in the direction of arrow 0, Fig. 6. Fig. 8 is a plan view of the shuttle detached; and Fig. 9 is adetached detail showing the attachment of the end of the link to the operating-arm, as will be hereinafter described. Fig. 10 is a detached detail showing a side view of the pivotal connection of the shuttle-supporting arm shown in Fig. 5, as will be hereinafter described. Figs. 6 to 10 are shown on an enlarged scale.

In the accompanying drawings, 1 is the breast-beam.

2 is a stand secured to the inner side of the breast-beam and extending out therefrom in a horizontal plane. To the arm 2 of the stand 2 is in this instance adjustably secured by a bolt 3 a plate 3, having a bearing 3" at its outer end for a vertically-extending shaft 4, which has secured upon its upper end a collar 4 and the inner end of the oscillating needle 5. The needle 5 preferably has an upwardly bent or curved end 5', with a hole therein through which the thread passes. The shaft 4, which is the pivotal point of the needle, is located insuch a position that at the forward beat of the lay to the fell of the fabric said shaft will be substantially in the same line or plane as the reed. (See Fig. 3.)

On the lower end of the shaft 4 is secured an arm 6, carrying a pin or roll 6, (see Fig. 3,) which extends into and travels in an inclined or cam slot 7 in the plate 7, in this instance adjustably secured by screws 7" to a bar or plate 8, extendingin a longitudinal groove or recess in the upper side of the lay 9. (See Fig. 3.)

To the outer slotted end of a side extension 2 of the stand 2 is adj ustably secured in this instance by a bolt 10 the end of a curved bracket or arm 10, upon the outer slotted end of which is adjustably secured by a bolt 11 the shuttle-holder 11, containing a shuttle 12 therein.

The shuttle 12 carries the selvage or tie thread 13, which forms, in connection with some of the warp-threads, the selvage on the woven fabric 14, which passes over the rod or roll 15, mounted in bearings 16, secured upon the inner side of the breast-beam 1 in the usual way.

On the edge of the plate 3 is in this instance secured one end of a blade or guide 17, which has at its end a hole through which passes the filling-thread 18 to and through the upturned end 5 of the oscillating needle 5. The blade or guide 17 acts as a tension for the filling-thread.

The operation of my improvements will be readily understood by those skilled in the art. Supposing the lay to be in its forward position, as shown in Fig. 1, on the rearward movement of the lay as the roll 6 on the arm 6 reaches the outwardly-inclined por tion of the slot 7 the continued backward movement of the lay causes the rotation of the shaft 4 and the consequent oscillating or swinging movement of the needle 5 to move it into the open shed formed by the warpthreads 19 19 (shown in Fig. 3) and carry the filling-thread 18 with it and into the shuttle-v holder 11 and over the shuttle 12. As the lay moves forward from the position shown in.

Fig. 2 the inclined portion of the slot 7, through the roll 6 on the arm 6 traveling therein, rotates the shaft 4 and moves the needle 5 back out of the shed to its first position, causing the filling-thread 18 to pass under the shuttle 12 and out of the shuttleholder 11 and back through the shed, to be beaten up by the reed as the lay moves to its forward position. (Shown in Fig. 1.)

In the modified construction shown in Fig. 5 a slight vibratory motion in a horizontal plane is communicated to the shuttle-holder 11 and to the shuttle 12 at the proper time to move the shuttle toward and away from the fabric as it is being woven. V

In Fig. 5 at the end of the said extension 2" of the stand 2 isa hub 2, forming a bearing for a vertical shaft 23, on the upper end of which is fast the end of the bracket or arm 10", corresponding to the bracket or arm 10 in Figs. 1 to 4:. To the lower end of said shaft 23 is fast one end of an arm 22. (See Fig. 10). The other end of said arm 22 has pivoted thereto one end of a link 21. The other end of said link 21 is connected by a pin 21 to the hub of the arm 6, fast on the vertical rotat-: ing shaft 4, (see Fig. 9,) tomove with saidhub. I

It will be seen that the rotation of the shaft 4, as the needle 5 moves into and out of the shed will communicate motion to the link 21 and,

through the arm 22, a slight rotating motion to the shaft 23 to cause the supporting-arm 10" and the shuttle-holder 11 to move the same toward and away from the fabric as it is being woven.

The shuttle 12 preferably has an offset spring 12 on one side, which acts as a tensionspring for the thread in the shuttle.

The advantages of my improvements will be readily understood by those skilled in the art. The mechanism for oscillating the needle is of simple construction and a positive motion is communicated to the needle into and out of the shed. The blade or guide 17 produces the proper tension on the fillingthread.

-It will be understood that the details of construction of my improvements may be varied, if desired.

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

1. In a needle-motion of a loom, the combination with the oscillating needle having its free end bent or turned to extend out of the plane of the body of the needle for the filling-thread to pass through said end, and a tension blade or guide stationary at one end for the filling-thread to pass through its free end before passing to the needle, substantially as shown and described.

2. In a needle-motion of a loom, the combination with the breast-beam and a support extending out therefrom, a needle pivotally mounted on said support, a shuttle-supporting arm and a shuttle-holder on said arm, and a shuttle in said holder, of a lay, and a plate having a cam-groove therein attached to the lay, to operate the needle through intermediate mechanism, and said mechanism, substantially as shown and described.

3. In a needle-motion of a loom, the combination with the breast-beam, of a supporting-stand, an arm secured to said stand carrying ashuttle-holder, and said shuttle-holder, and an oscillating needle, and connections intermediate said needle and the shuttle-holdersupporting arm, to communicate a slight oscillating motion to the shuttle-holder and the shuttle, on -the movement of the needle, substantially as shown and described.

4. In a loom, the combination with a shuttle-holder and a shuttle held thereby to supply a selvage or tie thread, of a swinging or oscillating needle having its free end bent or turned to extend out of the plane of the body of the needle and provided with an eye for the filling-thread to pass through, substantially as shown and described.
