To all whom t may Concern: p

Be it known that I, PETER MAcPHnRsoN, a citizen of the United States, residing at IVorcester, in the county of l/Vorcester and State of Massachusetts, have invented a new and useful Cartridge-Belt Loom, of which the following is a specification.

This invention relates to a new arrangement of the warps in a cartridge belt loom.

In weaving cartridge belts, which consist of several plies of fabric woven one' above the other, but of different lengths, it is necessary to have a separate warp for each ply. The threads from these various warps have to be arranged so that they do not twist around each other and so that the tension can be arranged for the various warps to give the necessary different lengths of plies after the fabric is woven. The usual arrangement of warps closes up the back 0f the loom in such a way that it is difficult for the weaver to get her hands between the various warps and open up the threads so as to get a broken thread untwisted from around the other threads and draw it back through the heddle straight from the warp, which is very essential t0 good weaving. My invention consists of a new arrangement of the warps in the back of the loom so that the weaver can both see and get her hands between the various warps much better than in fthe old arrangement, thus very materially facilitating the manufacture of cartridge belts.

Reference is to be had to the accompanying drawings, in which Figure 1 is a perspective view of a portion of a cartridge belt loom showing a preferred embodiment of this invention, and

Fig. 2 is a diagrammatic side elevation of the same.

The weaving elements of the loom will not be described as they constitute no part of this invention. It will be understood that the loom has the usual means for forming the shed, and it will be seen that it also has the usual frame provided with means for supporting the bottom warp 10 in the usual place below the shed. Ordinarily the top warp is supported just above the shed. Also the top reinforcement warp 11 and the bot tom reinforcement warp 12 are shown in their usual places above. According to this invention, I have taken the main warp 13, which is usually called the top warp, out

of themiddle of the loom just above the shed vand provided a pair of brackets 14 mounted on the loom frame just above the ioor and having bearings for the warp beam studs. This locates the top warp beam down near the floor below and at the rear of the bottom warp beam 10. It leaves an open space where the top warp beam is usually. located over the shed and under the reinforcement warps.

The yarn comes'up from the top warp beam over the rods 15 which separate it from the bottom warp and the other warps, and then straight through to the heddles. The binder warp 16, which is usually located at the bottom of the loom, is moved up to a position near the top and supported on the brackets 17 which support the top and bottom reinforcements. These brackets are usually provided with several arms for the shafts and rods, and I make use of one pair of these arms for supporting this binder warp beam shaft.

It is to be observed that the number of threads from the binder and reinforcementl warps is very small, while the'number of threads coming up to the shed from the top warp is comparatively large, extending clear across the fabric. For that reason this arrangement of warps makes it much easier for the weaver to see when there is anything wrong with the threads. In case of tying in a new warp or tying in a number of ends at one time, it is much easier to get them in straight than it was with the Old arrangement. The spacing of all the warps a material distance above the shed provides a clear space entirely free from the warp threads just above the warps where they pass horizontally in through to the heddles. Through this space the weaver can see without any diflicultv and into it she can get her hands for making any necessary changes or connections. This not only makes it easier for her, but materially facilitates and speeds up the work.

Another advantage of a smaller degree is that the comparatively heavy top warp beam does not have to be lifted up into the loom, but can be practically rolled along the floor into place.

Although I have illustrated and described only one embodiment of this invention, I am aware of the fact that many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim.

Therefore I do not wish to be limited to all the details of construction herein shown and described, but what I do claim isr- In a cartridge belt loom, the combination with rwarp separating rods extending across ythe loom, means below and in front of them for supporting the bottom warp extending only part way across the loom, and means above them at the top of the loom for supporting the reinforcement warps, the last named means being spaced materially above the rods and the space above the rods at the rear of the loom being free from warp beams to facilitate inspection and manipulation of the threads, ofmeans also located below and behind the rods and at the bottom of the loom below the top warp beam forsupporting the top warp, and means above the rods for supporting the binder warp at the rear of the reinforcement warps.

In testimony whereof I have hereunto affixed my signature.

PETER MACPHERSON.
