S?ECIFIOATION forming part of Letters Patent N 0. 650,562, dated May 29, 1900.

Application filed August 8, 1899. Serial No. 726,537. (No model.)

To all whom it nuty concern:

Be it known that I, THOMAS WILLIAM MILL- WARD, carpet manufacturer, a subject of the Queen of Great Britain and Ireland, residing at Albert Mills, Levenshulme, near Manches ter, in the county of Lancaster, England, have invented certain new and useful Improvements in Loom-Shuttles, of which the following is a specification.

This invention relates to an improved sh u ttle for weaving chenille carpets, rugs, or other similar fabrics in which a fan or V-shaped fur or pile weft forms the distinctive feature, the object being to devise a simpler means than those hitherto in use for the same purpose and which results in greater economy of time, labor, and mechanism. Hitherto fabrics of this class have been woven both in hand and power looms. In the former case the chenille weft or fur is generally wrapped longitudinally on a long stick or staff with notched ends, by means of which it is passed through the shed by the weaver. The method most generally in use, however, in powerlooms is to wind the chenille-weft on a beam or large bobbin or place it in a basket, either of which is placed in a suitable position about the loom, the weft being then led to an apparatus by which it is laid through the shed. By this method the use of somewhat intricate mechanism is required to lay the weft through the shed, to operate the catcher 0r pile-tying warp, and to guide the latter into proper position. Needless to say this mechanism forms part of looms specially built for the purpose, and which, moreover, are expensive and somewhat slow to operate. According to my invention I dispense with the present means of carrying the weft or fur across the loom, with the arrangement of needle-bar and catcher-warp, the open-spaced reed, and other details common to it. Instead of these my invention consists, essentially, in placing the fur or weft in an untwisted state in a case or cases which maybe carried in a shuttle or other suitable carrier capable of being picked across the shed in a change box-loom by means of the usual picking mechanism.

The invention will be fully described with reference to the accompanying drawings, in which Figure 1 is a side elevation of a shuttle or carrier adapted to the purposes of my invention; Fig. 2, a plan of same; Fig. 3, a longitudinal section; Fig. 4, across-section on line or y; Fig. 5, a longitudinal section of fur or weft container; Fig. 6, a side elevation of same, and Fig. 7 an end elevation.

I would have it understood that these are only given as examples of how my invention may be carried into effect, the details being capable of alteration withoutdeparting from the spirit of the invention.

a is a shuttle-body hollowed out in the center 1) and is provided at the open side with an elastic web 0, steel spring-plate, or the like, which is connected to a pin d at one end, while at the other end it is provided with a hook e to engage with another pin f, so that when stretched the web covers the open side of the shuttle. All these parts are well known.

The principal feature of my invention consists in the use of a case g, which may be of any suitable shape or size that will enable it to be passed through the warp-shed easily,

the shuttle or carrier being made to corre-v case at n and then turned around the end, the

loose end of the flap being provided with a hookt' to engage with an eyelet j in the case. The flap is provided with a metallic guide-eye 7a, through which the fur may be led, being afterward passed in the direction of the line shown around pins Z to the eye m of the shuttle or carrier, the whole of which arrangements are designed to keep the fur straight and at the proper tension. The case 9 is preferably placed in the shuttle or carrier, with the flap it against the side ofthe latter, and is kept in position by the web 0. I would here say that it is quite possible to make the case 9 to serve both as the weft-container and as its own carrier; but at present I prefer to make it separate from the shuttle or carrier, which latter, as already indicated, may be of any suitable or convenient shape.

class of fabric being made, and such is the 1 l The case g may be filled with fur by any suitable means, such as by first passing it through a number of guide-eyes arranged on a frame and designed to take out the twist and thence feeding it into the case by a pair of small revolving rubber rollers. As the fur is fed forward it is from time to time pressed into the tube by a wooden rod or the like, so that when full the case contains a considerable length of fur, which is laid across it in transverse layers. Any number of cases may be used in accordance with the size of the fabric being woven, each case being numbered inprogressive order for use in the loom, so that the proper pattern may be woven as will be well understood by those in the trade.

By means of my invention I am enabled to weave chenille fabrics in a change box-loom with, say, two boxes and the usual and necessary warps for the particular fabric in hand. The chenille-furis passed through the catcher warp-shed from the top box, the backing-weft being woven from the bottom boX. shot is picked every third or fifth shot, or as required by the quality of the fabric produced. The warps are operated by heddles in the usual well-known manner for the nature of the back required. After the chenille-carrier is picked the loom is arranged to stop or dwell while the Weaver adjusts the fur to the pattern, after which the backing-weft is put in, and this cycle of operations is repeated until the fabric is finished.

Either fan or V shaped, round, or twisted fur may be used in the cases, according to the The fur simplicity of the method of weaving it that it leaves the case with very little friction, no breakages, and entirely without twist. Consequently I am enabled to use the methodboth for narrow and wide goods and to weave each with less expenditure of time, labor, and mechanism than is now the case.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a device of the character described, a shuttle, a tubular case fitting therein, a flap attached at one end to a side of the case eX- tending across the mouth of same and removably attached at its other end to the opposite side of the case and an eyelet formed in said flap where it crosses the mouth ofv the case, substantially as described.

2. In a device of the character described, a

shuttle, a tubular case fitting therein, a flap attached atone end to a side of the case extending across the mouth of same, a hook on the other end of the flap for engaging the opposite side of the case and an eyelet formed on said flap where it crosses the mouth of the case, substantially as described.

3. In a case for holding chenille-weft the combination with a tubular body g of a hinged flap 71- having a metallic guide-eye 7c and hook 'i engaging with eyelet j in said case substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
