LOOM FOR WEAVING CHENILLE FABRICS.'

SPECIFICATION forming part of Letters Patent No. 625,841, dated May 30, 1899.. Application tiled April 11l 1898. Serial No. 677,123. (No model.)

To MZ whom t may concern: r

Be it known that I, HARRY I-IARDwIcK, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented anew and use ful Improvement in Looms for Weaving Chenille Fabrics, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which form a part of this specication.

In the weaving of chenille fabrics as now generally carried on, whether the chenille be the ordinary chenille, in which the tufts or fur projects from both sides, or the Axrninster type, in which the fur projects from one side, the fur or chenille weft is first prepared according to a prearranged pattern. After each pick of said weft it is placed in correct contiguity with the preceding contiguous weft by the operator, who has before him the pattern and arranges successive weft-picks by hand to bring the proper colors in contiguity to carry out in the fabric the correct pattern shown in the design. This necessitates the use of skilled operatives, is somewhat slow,

and often results in mistakes prejudicial to the finish and correct design of the fabric.

My invention has for its object to reduce the skill necessary for .the operatives and to make the Weaving more rapid, and thus reduce the cost.

It also has forits obj ect to make the setting more certain and thus reducing'to a minimum the mistakes in the fabric, and thus increasing the finish and correct design of the fabric.

To that end, While still employing the ordinary warp, which may be operatedv by shafts Y devices may be the mark of a position of a given color of the weft thrown or may indicate the beginning and ending of the figure and ground or any desired prearranged scheme; but in any event the operator has only to locate the prearranged indicia upon the weft with relation to the declaration of the indicating devices.

I will now describe the embodiment of my invention as shown in the accompanying draw ings. I

Figure l is a diagram showing my improved method of indicating the change of color by means of the Warp. Fig. 2 is a perspective View of the fabric and the upper warps. Fig. 3 is a plan view of a modified form of indicating device. Fig. 4 is a detail perspective of a portion of Fig. 3. Fig. 5 is a diagram of another rnodiiied form.

Where the warp used inweaving the fabric is fine enough and sufcient in number, I prefer to use this same warp as indicating devices. Such construction is shown in Figs. l and 2. In that construction A A A2 A3, &c., represent the warp, which is connected to the shafts B inthe ordinary manner. This warp is connected to tails h and ext-ends through orifices in the shafts, having the knot b to enable it to be lifted by the shaft. The tails b extend beyond the shaft and are connected to the hooks C of an ordinary jacquard lifted by the griff or knife D Vand controlled by the needles E, operating the cards in the or din'ary manner. The lift of the jacquard is made greater than the lift ofthe shaft, so that l when a warp is lifted vby the jacquard it is elevated higher than the lift of that or any other warp by the shaft. The jacquard is so arranged as to operate for each pick of the tuft or fur and the'card controlling the hooks to be lifted so cut that the Warp is lifted by the jacquard at the desired indicating-points and, being liftedhigher than any warp lifted TOO it is shown after a pick has been thrown and the warp at those points lifted by the jacquard to a higher level than the warp lifted by the shafts. The operator has, therefore, only to set the proper color at those points mechanically, and the pattern is followed with certainty and celerity. The cards are of course so out that after each pick throughout the weaving the Warp at the proper point will be lifted by the jacquard.

Of course I do not intend to limit myself to any particular form of jacquard or equivalent mechanism. A lifter-board jacquard wpuld operate equally Well, or a dobby, or any kind of mechanism in which, through or by the indication of a card or series of cards or equivalent device, any one or a plurality of warps may be lifted. This is of course a general definition of a jacquard, and also equally applies to kindred mechanism to accomplish the same result, and when I use the term jacconnected to a jacquard apparatus.

quard-machine I intend to include, broadly, any such mechanism as would be covered by this definition.

Inv Figs. 3 and 4 I have shown another form of embodiment of my invention. In this embodiment instead lof using the warp as indicating devices I use a series of pins F, projecting from a box G across the loom. As may be seen, these pins are acted upon by the spring f to hold them normally projecting through the oriiicesf in the box. Each pin is connected to a tail 7L, which extends backward along and beyond the box and are each Not shown.) The operation is similar to thtt of Figs. l and 2, the difference being that the action of the jacquard pulls the pin operated into the orilice, leaving an open space to indicate the point where the setting is to be done. When the jacquard descends, the springf returns the pin.

In Fig. 5 I have shown the same general form of embodiment of my invention shown in Figs. l and 2 applied to a fabric in which the Warp A AQ dac., used in Weaving the fabric are too few in number across the loom to provide sufficient number of indicating devices across the loom to set the pattern absolutely. In that case I use supplemental warp J, which are connected to the jacquard, but not to the beam, and in the loom'lie below the regular Warp, so as not to interfere with the Weaving. After each pick the predetermined warp are lifted bythe jacquard to indicate the setting-points- The specific embodiment of my invention shown in Fig. 5 and described in the foregoing specification, which consists in combining with the shafts and regular warp connected therewith a plurality of su pplemental warp, a jacquard, and'connection between said supplemental warp and the jacquard for the purpose specified, is not specificially claimed herein, but forms the subject-matter of and is specifically claimed in a separate application iiled by me April 8, 1899, Serial No. 712,201.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-

l. In looms for weaving chenille fabrics, the combination of a plurality of indicating devices extending across the loom, a jacquard mechanism and connection between said indicating devices and the jacquard mechanism for the purpose specified.

2. In looms for Weaving chenille fabrics, in combination with the shafts, of a plurality of warp connected therewith, a jacquard-machine, and connection between said jacquard and the warp for moving parts of the Warp out of the plane of the warp' for the purpose specified.

3. In looms for Weaving chenille fabrics, in combination with the shafts, of a plurality of warp connected therewith, a jacquard-machine and connection between said jacquard and the Warp, the lift of the jacquard being greater than the lift of the shaft lfor the purpose specified.

Signed by me, at Philadelphia, Pennsylvania, this 23d day of March, A. D. 1898.
