NEEDLE-LOOM.

SPECIFICATION forming part Of Letters Patent NO. 719,666, dated February 3, 1903.

Application filed October 3, 1901 Serial No. 77,350. (No model.)

To a, whom it may concern:

Be it known that I, EDUARD HERZIG, a citizen of the United States, residing at Union Hill, Hudson county, New Jersey, have invented certain new and useful Improvements in Needle-Looms, of which the following is a specification.

My invention relates to looms, particularly to such as are intended for weaving narrow fabrics, such as ribbons, and has for its object to provide a simple and efficient construction for rapidly producing the fabric and for securing a close and even mesh.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, in which Figure 1 is a side elevation of myimproved loom with parts in section. Fig. 2 is a sectional elevation thereof on the line 2 2 of Fig. 1. Fig. 3 is an enlarged longitudinal section of that part of the machine at which the weft is inserted. Fig. 4 is a plan of the same parts. Fig. 5 is a detail plan of a slide for operating the weft-spools. Fig. 6 is an elevation showing the tension mechanism for the weftthreads on an enlarged scale. Fig. 7 is a detail of the selvage-spools, and Fig. 8 is a sectional elevation of the weft-carrier shafts and the parts connected therewith.

The machine comprises a frame A, having a main shaft B, from which the heddles C are operated by means of any approved mechanism, such as indicated at D.

E is the drum from which the warp F is supplied, said drum being provided with a cord E and weights or any other tension mechanism.

G indicates the Weft-threads, one on each side of the machine, and each of said weftthreads passes from a supply-spool H through an eye I, a double eye J, another eye K, and in contact with a roller L. From there the thread G passes alternately through eyes M and tubular guides N, the latter being stationary, while the eyes M are secured upon a bar 0, pivoted at Oand drawn upward by a spring P. From the outermost eye M the thread G passes through a guide Q and then through guides R, carried by the lay R,which may be arranged and operated in the usual manner by means of a bar S, having a crankpin connection with a gear-wheel T, driven from the counter-shaftU and from the main shaft B by means of gearing V W. The finished fabric passes over a guide portion A of the frame to a roll X, which is periodically rotated by'means of gearing Y, and aratchetwheel Z, driven by means of a pawl a, which is mounted on an arm a. This arm receives a periodical oscillating movement through the medium of a rod 1) and a bar 0, operated in any suitable manner. Adjacent to the guide A is located the weft-inserting portion of the machine, which is there provided with a support A, from which extend brackets din a direction parallel with that of the warp F and at each side of the same. These brackets are provided at their free ends with downwardly-projected pins (1, which. aline with similar pins (:1 arranged on the part A of the frame, the adjacent ends of the pins (1 d being spaced, as shown best in Figs. 2 and 3. On these pins d d are adapted to slide the selvage-spool holders 6, the construction of which is shown in detail in Fig. 7. These holders are provided with bottoms, on which rest the spools f, with curved slots f, through which the thread from the spools f passes out, and with elastic tongues f Below each spool-holder e is mounted to slide on the pin 61 a lifter g, adapted to be operated by an arm h, fulcrumed at h and provided with a downwardly-projected pin h This pin is adapted to be moved forward and backward, so as to swing the arm it up and down by means of a slide t', to which a reciprocating motion is imparted through the medium of rods j, connected in any suitable manner with a moving part of the machine. Each of the slides i is of the specific construction shown in Figs. 3 and 5 and is provided with a recess 1, within which is located a guide 1', preferably in the nature of a spring, and with guides i pivoted at i said guides being arranged obliquely with reference to the guide i. It will be understood that assuming the pin 72. to be in the central position shown in Fig. 5 and the slide to move in the direction indicated by the arrow in said figure the pin 7L2 will come in contact with the inclined guide t and will thus be brought into the angle formed by the two guides 2' i IOC and finally the guide tyielding the pin 72, will be forced past the guide 2' This movement of the pin 71 will correspond to an upward movement of the lifter g and the spoolholder 6. As soon, however, as the pin [7, is clear of the guide 2' the weight of the spool and of the lifter, together with that of the arm h, will cause the pin 712 to move back to its original position, as indicated in dotted lines in Fig. 5. Then when the slide 1' moves in the direction opposite to the arrow,thepin 71- upon comingin contact with the guide t will swing the latter on its pivot 2' and thus pass into the central space between the two guides 71 to then impinge against the inclined face of the other guide 71 when the operation will be repeated in substantially the same manner. Adjacent to the selvage-spool holders 6 and at a point located centrally with respect to the warps F is located a shaft 70, perpendicular to the plane of the warpsthat is, vertical said shaft carrying at its upper end the hub m of a weft-carrier n, which is formed at its end with an eye 0 and adjacent thereto with checks 77. At its lower end the shaft has a gear-wheel Z. On the shaft 7t is loosely mounted a tubular shaft 70', carrying a gearwheel Z and the hub m of another weft-carrier n. The two weft-carriers are substantially alike, except that they extend in opposite directions. They rise gradually from the hubs an m along what may be practically termed a spiral line, it being understood that the eyes 0 o are at the highest portion of each weft-carrier, while the hubs m m are at the lowest portion of such carriers. The gearwheels Z Z are in mesh with racks p p, to which a reciprocating motion is given by means of levers r, drawn toward each other by means of a spring 7". The said lovers are moved from each other by means of a cam s acting on studs or rollers r and secured to a shaft 8, which is driven from the countershaft U by means of bevel-gearing 25. Between the two spool-holders c are arranged stationary guides u, each of which is provided with a slot to at about the same level as the space intervening between the adjacent ends of the pins d d The arrangement of the weft-threads G is as follows: They pass forward from the spools H through the tension device previously described and through the guide R of the lay to the eyes 0 0, then inward to the fabric, it being understood that one weft-thread is wound off the spool I-I while the other weft-thread winds off the spool H on the other side. The selvage-threads g, which wind off the spools f, extend inward to the outermost warps F and are interwoven with the wefts G, the two weft-carriers swinging through the shed alternately and the spools f being each low ered at the time the corresponding eye 0 or o is in its outermost position. By the rising and falling of the spools f the selvage-thread on each side is interwoven with the weft, thus forming a secure edge for the fabric.

The fabric is thus extremely strong and durable.

In detail the process of weaving is as fol.- lows: The weft G, shown at the bottom in Fig. 4, has reached the position represented by a swinging movement of the weft-carrier.

n, and while this movement took place the corresponding selvage-spool carrier was in its upper position, so that the weft-thread passed under the selvage-thread q. After the weft-thread passed through the shed (downward in Fig. 4) the corresponding selvage-spool carrier 9 dropped into the position shown best in Fig. 3, so that the part of the selvage-thread adjacent to the spool-carrier came to be below the portion of the weft which extends through the shed, as also clearly appears in Fig. 3. Thus when the weft-carrier n swings forward, or to the right from the position shown in Fig. 4, it carries the weft over the selvage-thread instead of under the same, as before, and the result is an interweaving or interlocking of the weft with the selvage thread. At the same time one selvage-spool carrier 6 is lowered the other is raised. When, therefore, the weft-carrier n, after passing through the shed, lays the weft G in the slot to of the guide to, shown at the top in Fig. 4, said weft passes under the selvage-thread g at the top of Fig. 4. Then the spool carrying this selvage-thread is lowered and the weft-carrier n returns to its original position, whereby the weft is interlocked with the selvage-thread at the top of Fig. 4. After the weft-carrier n has thus returned to its original position the shed is changed and the weft-carrier n is operated in a corresponding manner to carry the other weft-thread through the shed first in one direction and then back, this weft being interlocked with the two selvage-threads in the same manner as described with reference to the movement of the weftcarrier 71. By the use of the guides to, located between the selvage-thread carriers and the warp or web, I preserve that portion of the selvage-thread which is adjacent to the warp in a horizontal position, and, moreover, I prevent the weft from being dragged down by the weight of the selvage-thread and its carrier.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a loom the combination of means for holding the warp, and for forming the shed, with weft carriers movable transversely through the shed, a selvage-thread carrier movable at an angle to the plane of the warp laterally of the web, and a guide for the selvage-thread and for the weft, which guide is located between the selvage-thread carrier and the warp.

2.
