LOOM FOR WEAVING VELVETS.

SPECIFICATION forming part of Letters Patent No. 703,580, dated July 1, 1902.

Application filed March 9, 1901.

To all whom it ntay concern: 7

Be it known that I, WILLIAM G. HARTLEY, a resident of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Looms for Weaving Velvets; and I do hereby declare that the following isafull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to looms for weaving velvets or plush, producing the loops that form the face or pile of the velvet when out by means of stationary wires extending through the reed and resting on thecloth. It is fully described and illustrated in this specification and the accompanying drawings.

Figure 1 is a sectional diagram showing parts of the loom and the relative position of the new devices to the usual parts looking in the direction of one end of the loom. Figs. 2, 3, and 4 are diagrams from the front, showing the position of the devices that form the pileloops at different stages of the operation, as will hereinafter be explained. Fig. 5 is a perspective view of one of the flattened wires over which the pile-loops are made. Fig. 6 shows a side View of one of the flattened loopwires with a knife at the end to cut the loops.

The object of this invention is to facilitate the weaving of velvet on a plain or figured ground of the sameor of a different material and have the loops face in the direction of the length of the goods instead of toward one side, to facilitate the cutting of theloops by shearing instead of running a blade through them.

In Fig. 1, in which the weaving is represented as being done on a plain ground, Ais the usual yarn-beam that carries the warp for the ground fabric on which the velvet is woven. B B are the heddles'or harnesses that control this warp. D is the reed. O is a flattened wire held at c on a rod, its front end passing through between the dents of the reed D and resting at its front end on the surface of the cloth J. The shape of the wire 0 is shown in Figs. 5 and 6. The improvement consists in this flattened wire 0, extending through the reed D to form the loops over, by

means of a doup-heddle which consists of the Serial No 50,413- (No model-l shield N operated by the lower harness-bar P, and a looped wire F guided in eyes e on the shield N and operated by the upper harness-bar E, and which wire F carries the pilewarp 01,, held on the auxiliary yarn-beam L. An auxiliary harness R is placed between the doup and the regular ground-warp harnesses B B, to move the pile-warp a vertically while the wire F of the doup-heddle is moved laterally to guide it down each side of the wire O alternately to form the loops. The shield N always passes down to the left of the wire 0, and the auxiliary heddle R, that carries the pile-warp, passes down to the right of the same wire, and that heddle would keep the loop-warp on the right side of the wire 0 allthe time if the loop-warp were not drawn down on the other side of the wire 0 by the loop-wire -F through the loop at the end of which that warp passes after leaving the auxiliary heddle B. When the shield N goes down with the loop-wire F, the eye 6, fast to the shield and through which the wire F passes, controls the end of the wire F and compels it and the loop warp-thread in it to go down with the shield N on the left side of the wire 0 and make a loop over that wire, the front leg of which loop is locked down by shuttlethread; but the back leg of the loop is brought back to the right side of the wire 0, when the shield N rises again, and the loop-wire F goes down again withoutthe shield N, and the eye e remains so far above the wire 0 (see Fig. 4) that the end of the loop-wire F is not controlled by it, but allows the loop-wire and warp-thread in it to be drawn over to the right of the wire 0 by the auxiliary heddle R,always on that side of the wire, and then down to form another loop to the right over the wire C to be bound by the passage back of the shuttle-thread.

In Fig. 2 the shield N is represented as being drawn down by its harness-bar, and the looped wire F, being connected by the eye 6 to the shield N, is carried down between the wire C and the shield, and the pile-warp 06 is carried down with it and is bound by the shuttle passing over it and under the wire 0.

In Fig. 3 the upper and lower doup-harness bars E P, which are operated independently by separate cams, are both carried up, and in Fig. 4 the lower doup-harness bar 1?, that moves the shield part of the doup, has remained up, and the eye 6 is held so high it allows the wire F, with the pile-Warp oz, to be drawn over that side by the moving of the auxiliary harness R, which also carries that pile-warp. The loop over the wire O is again made and bound down as before by the shuttle and filling passing over it, and the lower harness-bar P goes down and the upper harness-bar E goes up again, and the next move is to the first position, as in Fig. 2. This sequence of motions is repeatedly made and a series of loops of the pile-warp a are formed over each wire C, which loops are drawn off at the front ends of the wires as the cloth is drawn over the breast-beam S by the take-up motion. (Not shown.) Any number of the flattened wires 0 maybe used either in groups or otherwise, and any number of harnesses or shuttles may be used, according to the style of goods desired. The invention is not confined to any particular form of doup-heddle, but may be varied, if necessary, for heavy or light fabrics.

A whip-roll T or other like device is shown, Fig. 1, to draw the necessary amount of pileyarn from the auxiliary yarn-beam L to allow for the motions of the doup-heddles and to form the loops over the wire 0. Though it is intended to cut the loops by shearing, they may be out, if preferred, by forming the end i; of the wire 0 in the usual knife shape, (see Fig. 6,) so that the loops will be cut as they are drawn oif of the wire.

The mechanism for operating the different parts is not shown or described, as no particular way is claimed and most any of the various kinds may be used as may be upon trial found advisable.

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent- In a loom for weaving loop or pile fabrics the combination of a reed, one or more wires held at their back ends and extending through between the dents of the reed parallel with the warp-threads with their front ends resting on the woven cloth, one or more doupheddles, and an auxiliary heddle to control a pile-warp, substantially as described.

In testimony whereof I have hereunto set my hand this 5th day of March, A. D. 1901.

WILLIAM G. HARTLEY.

In presence of- I'IOVVARD E. BARLow, EDGAR S. MARSH.
