SPECIFICATION forming part Of Letters Patent N0. 614,504, dated November 22, 1898.

Application filed March 25, 1898. Serial No. 675,179. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN SHINN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Switch-Heddles for Cross- Weaving, of which the following is a specification.

My invention relates to looms for crossweaving, and said invention I have named a switch-heddle, which I use to switch and guide one warp-thread over another warp.- thread in weaving gauze fabrics, chenille, and other cross-woven fabrics.

My improved heddle I also use to switch and guide a pile warp-thread over a longitudinal pile-wire in weaving a pile fabric.

Previous to myinvention of the switch-heddle cross-weaving has been done by doup-heddles or shifting-needles. The doup is not durable unless made of metal and chafes the warp-threads. If the needles are shifted by a guide-comb, said comb is in the weavers way when inserting broken warp-threads.

My improved sWitch-heddle is cheap, durable, positive in action, and is no obstacle in replacing broken warp-threads.

My invention consists in a series of switchheddles so mounted in two heddle-frames that one heddle of each frame make a pair and so work in combination with a needle having an eye at the point and carrying a warp-thread to be crossed or a longitudinal pile-wire, upon which wire is formed a pile, by crossing the pile warp-threads, as illustrated in the accompanying drawings, making a part of this specification, inwhich- Figure 1 is a vertical longitudinal section of so much of a loom as is required to show my improvement for cross-weavin g one warpthread over another warp-thread. Figs. 2 and 5 are sectional end elevations of a heddle-frame for mounting the switeh-heddles. Figs. 3 and 4 are front sectional elevations of two heddle-frames. The two make a pair. Figs. 6 and 7 show a series of switch-heddles, needles, and a section of the needle-supporting bar. Fig. 8 is a face view of one of the needles and a-sectional end view of the needlesupporting bar. Fig. 9 is a vertical longitudinal section of so much of a loom as is required to show my invention for weaving pile fabrics on longitudinal pile-wires. Fig. 10 is a side view of a pile-wire such as I use for weaving a terry pile fabric.

The parts are marked with numerals, an like numerals indicate same parts in all views of the drawings.

Previous to describing the construction and operationof my invention I would say that my invention lies solely in the switch-heddle. The other parts shown in the drawings are old and disclaimed by me and are only claimed in combination with the switch-bed dle. For that reason I shall be brief in describing these parts that are old.

1 represents the switch-heddle, whichI prefer to make of cold-rolled flat strips of steel or iron, No. 26 wire-gage, three-eighths of an inch wide and about twelve inches long, more or less. At each end are punched holes for the stringingbars 2. In this flat strip is swaged a projecting cam 3. This cam is swaged the full width of the metal strip, as shown in Figs. 2 and 5. The projecting distance of the cam 3 will be governed by the number of switch-heddles to be used in the inch space. This cam I prefer to place near one end, say about two inches from the end. These switch-heddles are strung on the bars 2 in the heddle-frames, as shown in Figs. 2, 3, 4., and 5, which frames are of ordinary construction except the stringing-bars 2, which I prefer to be round. The top one I space.

with shallow notches, as shown in Figs. 3 and 4.

In mounting the switch-heddles, Fig. 3, the cams all project to the right, those in Fig. 4 to the left hand.

4 represents the needle, which I prefer to make of strips of spring-steel, about No. 23 wire-gage thick, three-fourths of an inch wide and ten inches long, more or less. These needles are set in a supporting-bar 7, which bar is divided by pins, as shown in Figs. 6 and 7, to receive the number of needles used per inch. This needle-bar is fixed in the loom,.as shown in Fig. 1, so as to bring the points of the needles between each pair of switch-heddleS, as shown in Figs. 6 and 7.

Fig. 3 we will suppose to be the front heddle-frame and Fig.4 the second heddle-frame.

The third or back heddle-frame in Fig. 1 carries ordinary wire heddles and operates IOO .. I I -I- the crossing warp thread. These heddleframes can be operated by the ordinary treadles and cams or may be operated by a pattern-chain-controlled heddle motion.

The switch-heddles to work well should have an up-and-down movement of about one-half of an inch and work one shot up and one shot down, alternately.

The third or back heddle-frame carries the crossing warp-thread 5 and works up and down every shot. I

Referring to Fig. 6,the front heddle is down. The ca ms 3 of these heddles push the needles to the right and under the cams above. This opens a passage for the crossing warp-thread 5 on the left of the needle. Fig. 7 represents the second heddle as down. This pushes the needles to the left and the thread 5 is switched and guided to the right" hand side of the needle.

It is plainly shown in Figs 6 and '7 that the cams on the right will switch the warp-threads 5 to the left of warp-thread 6, and the cams on the left will switch the warp-thread 5 to the right of warp-thread 6, and warp-thread 6 is crossed at every shot of weft, weaving a full gauze.

It is obvious to weavers that my switchheddle with the needle 4, as shown in Fig. 1, may be used as a selvage motion to crossweave a selvage where two breadths of cloth are woven in one loom and a selvage is desired at the point of separation.

Fig. 9 represents and shows so much of a loom mechanism as is required to show my invention when weaving a Brussels or VVilton carpet five frames.

In applying my invention to weave a pile fabric I substitute the pile-wire 4 for the needle 4 and operate the switches the same as shown in Figs. 6 and 7.

If a jacquard-machine be used and more than one pile-thread be used in each split of the reed, I use a heddle-wire in frame 22 with a long eye. In this eye all threads represented in Fig. 9 by numerals 17, 18, 19, 20, and 21, which are in the same split of the reed, pass through this long'eye. This longeye heddle is marked by numeral 23 in Fig. 9. Heddle-frames l3 and 14 carry ordinary wire heddles. They operate the body or binder warp-threads l5 and 16 usual in Brussels and Wilton carpet weaves.

If weaving tapestry Brussels, one pile warp-thread only is required in a split of the reed, and it will be operated by an ordinary wire heddle with a short eye in frame 22.

The pile-wire shown in Fig. 10 makes a terry-loop pile. If acut pile is desired,knives are arranged to work at one end of the pilewires and cut the loops as they pass off the left end of the pile-wire.

Longitudinal pile-Wires and knives to weave a loop or a cut pile are old and well known to weavers, and, as before stated, my invention lies solely in the switch-heddle,which switchheddles are operated in weaving a pile fabric in the same manner as before described for operating and crossing one warp-thread over another warp-thread. The pile-Wire 4. takes the place of the needle 4 and warp-thread 6.

In weaving a corded tapestry to be figured by a jacquard-machine two, three, four, five,

or more frames may be used for figuring warp-threads and one frame for the crossedcord threads 6. In this case the cord threads 6 take the place of the pile-wire 4 and are woven in the fabric, being completely covered by the figuring-warp threads, and make a good imitation of gobelin tapestry. Such fabrics the figuring-threads only show on the face and show in longitudinal cords like gobelin tapestries.

Having as above fully described my invention and mode of operation, What I claim as new, and desire to secure by Letters Patent, 1s-

A switch-heddle, provided with a switchcam, substantially as shown and described.

JOHN SHINN.
