LOOM SWORD Filed Aug. 15, 1960 ATTORNEY United States 53,081,799 LUDM SWORD Roy Mason, J12, Box 63, Qateechee, SAQ, and Berry W. Green, 149 Cumberland Ave, Easley, 5.6. Filed Aug. 15, 1960, Ser. No. 49,498 Claims. ((11. 139-188) This invention relates to textile looms and more especially to an improved loom sword.

This invention is concerned among other things with the problem of aligning the reed cap of a loom so that the reed wires may be adjusted to proper vertical alignment. In adjusting the reed wires an adjustment is first made so that the lay, carrying the lower reed frame, is in proper longitudinal alignment with the loom. The next step is to assure the proper vertical alignment of the reed wires by applying a square to the lay of the loom. Such adjustment has formerly been accomplished by employing a rasp to reduce the back portion of the reed cap adjacent the sword. This operation requires that the loom be stopped for a long period of time,

and if too much wood is removed from the reed cap,

it is necessary to place a shim between the reed cap and the sword, whereas, if too little is removed it is necessary to again remove the reed cap and further reduce the portion adjacent the sword. Because of this difficult, makeshift, inaccurate method of keeping the reed square, very often looms are operated with the reed out of proper alignment, thus increasing wear on shuttles, causing a poor quality of cloth to be produced and placing an undue strain on all of the loom parts because of the binding resulting from the reed being out of alignment.

Accordingly, it is an object of this invention to pro .vide an improved loom sword.

Another object of this invention is to simplify the problem of reed alignment.

An important object of this invention is the provision of an improved sword having an adjustable. upper portion so as to facilitate reed alignment.

Another object of this invention is to provide a loom sword having an adjustable and removable upper portion so that should the upper portion be damaged, it may be replaced without the necessity of replacing the entire sword.

Another object of the invention is to provide a loom sword facilitating a precise adjustment for loom reed alignment so that wear on other portions of the loom and its accessories will be reduced.

Still another object of the invention is to reduce down time resulting from the operation of reed alignment and improve the quality of cloth produced by the loom.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing forming a part thereof, wherein an example of the invention is shown and wherein:

FIGURE 1 is a perspective view of a loom, with parts omitted and parts broken away, illustrating a loom sword constructed in accordance with the present invention.

FIGURE 2 is an enlarged side elevation of the loom sword looking from the left-hand side of FIGURE 1, and

FIGURE 3 is a plan view of the loom sword illustrated in FIGURE 2.

Referring more particularly to the drawing, a loom frame is illustrated at 10. A loom sword having an upper adjustable portion A and a lower portion B is illustrated positioned adjacent the lower end thereof upon the usual rocker shaft of the loom. Means generally indicated at C are provided for positioning the upper A upon the lower portion B in sliding engagement so 3,981,799 Patented Mar. 19, 1953 Him? that the upper portion may be moved transversely of the loom. A threaded means D is provided for positively positioning the upper portion A during such adjustment and fastening means E are provided for fixing the upper portion with respect to the lower portion after an adjustment has been made. Thus, by adjustment of the upper portion A transversely with respect to the loom, the reed may be adjusted for proper vertical alignment in a very short period of time.

The lower portion of the loom sword B is illustrated in FIGURE 1 as being connected to the loom rocker shaft 11, which is longitudinally disposed in the usual manner adjacent the lower portion of the loom frame 10. The lower portion of the loom sword B has a split bearing 12, having an integral portion 12a and a removable portion 1% which is secured to the integral portion as by bolts 13 for securing same in fixed relation to the shaft 11. A rocking motion is imparted to the lower portion B of the loom sword so as to oscillate back and forth during the weaving operation.

The lower portion B includes a shank 14, which extends upwardly and carries the lay 15 within a suitable mounting 16. The race plate 15a, together with the lay wood 15b define a groove, 15c which carries the lower reed frame 17. The positioning of the lower reed frame 17 is relatively simple because the lay may be easily adjusted so as to be in proper longitudinal alignment with the loom. The invention is largely concerned with an improvement in the sword making easy vertical adjustment of the reed wires 18 possible.

The upper reed frame 19 is positioned within an arcuate groove 2% within the lower portion. of the reed cap 21. The reed cap 21 is secured on each side thereof by a bolt 22 passing through the reed cap and through a vertical slot 23 in the upper portion A of the loom sword and has a wing nut 24 threaded thereon.

Vertical adjustment of the reed wires 18 is accomplished by a transverse adjustment of the upper portion A of the loom sword. Such adjustment is accomplished by means C which is illustrated as including a support 25 carried by the lower portion B. The support 25 has a substantially horizontal flat surface 25a. A base 26 is carried by the upper portion A and has a fiat horizontal surface in sliding engagement with the surface 25a. It will be noted that the surface 25:: also defines a groove 25b to accommodate a tongue 26b to thus form a tongue and groove joint between the upper portion A and the lower portion B of the loom sword. The support 25 carries an abutment 27 spaced therefrom and integrally joined thereto by a rearward projection 27:: which is integral with the support 25. The abutment 27 carries a transverse horizontally disposed threaded member 28 therein. The threaded member 28 is threaded into the base 26 as at 28a and is suitably fixed therein as by the pin 2%. By proper manipulation of the nuts 29 the upper portion A may be positively adjusted through the means C.

In order to assure that the base 26 is positively positioned upon the support 25, so as not to be moved by vibration occurring during weaving, a pair of aligned bolts 38 pass through transverse slots 31 ca1ried by the base 25 into the support 25. Suitable washers 32 and lock washers 32a are provided to fix the position of bolts 30.

A precision vertical adjustment of the reed wires 18 is made possible by placing a square upon the race place 15a and making suitable transverse adjustment of the upper portion A of the loom sword as just described. Some of the important reasons for making an accurate vertical adjustment of the reed are stated above and it is evident that this operation can be carried out easily and quickly by adjustment of the nuts 29 and the bolts 555 39. If the upper portion A of the sword becomes damaged, this portion may be removed quickly and easily Without the necessity of replacing the entire sword.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
