LOOM FOR WEAVING FILE FABRIC.

SPECIFICATION forming part of Letters Patent No. 762,526, dated June 14, 1904. Application filed May 21, 1903. Serial No. 158,196. (No model.)

To all whmn it may concern.-

Be it known that LWILLIAM G. HARTLEY, a resident of Amesbury, in the county of Essex and State of Massachusetts, have invented cer- 5 tain new and useful Improvements in Looms for Weaving Pile Fabric; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the let- I ters of reference marked thereon, which form a part of this specification.

This invention relates to loom-s for weaving pile fabricsuch as velvets, plush, or the like-the object being to form and produce 5 the loops which when out make the face or pile of the velvet or plush.

These loops are formed by drawing'the pilethread over a stationary wire by a looper or carrier, which carrier is controlled in its ac tion by suitable cams, (lobby-head, or jacquard mechanism. By the use of my device, which is extremely simple and practical, the weaving of this class of looped goods is greatly facilitated. It is capable of being operated in 5 weaving velvets or the like on a plain or figured ground of the same or of a different material.

This invention is fully explained in this specification and illustrated in the accompa- 3 nying drawings.

Figure 1 is a sectional diagram showing parts of the loom and'the relative position of the new device to the usual parts looking in the direction of one end of the loom. Fig. 2

is an enlarged detail of one of the flat wires on which theloops are formed. Fig. 3 is a diagrammatic view illustrating the connections of the frames to which the carriers are attached to the jack-levers of a (lobby-head. Fig. 4 is 4 an enlarged detail of one of the flexible loopers or carriers extended, with a loopthread rove through its eye.

Referring to the drawings, in Fig. 1, which represents the weaving as being done on plain or twill ground fabric, A is the usual yarnbeam that carries the warp-threads from which the ground fabric is woven. On this ground fabric is formed the pile-loops, (see Fig. 1,)

which when out produce the velvet or plush effect. 5

B B are the heddles or harnesses that control the warp-threads, and D D are two frames similar in construction to the heddle-frames, but are for the exclusive purpose of carrying the looper or carrier E.

The principal feature of this invention is my improved method of forming the loop, which is performed by this looper or carrier E, that is constructed of a flexible cord, wire, leather, or any suitable material, and has an 6 eye 0 at or near its middle portion. (See Fig.

4.) The bight or doubled portion of the carrier is passed over the loop-wire C and the ends secured to the lower side of the frame D and D, respectively.

These two frames D and D are actuated to reciprocate alternately and in time with each other. Any suitable means-such as cams, jacquard mechanism, or dobby-headmay be employed to operate these frames. In Fig 3 I illustrate them as being controlled by the jacklevers F and F, which are attached to any ordinary dobby-head, the action of which jacks is well understood by those skilled in the art to which this device appertains.

In order to produce the required result, I prefer to use the first and second jacks to operate frame D and the third and fourth jacks to operate frame D, thus using two jack-levers for each of the carrierframes. My method of connecting the frame to the jacklevers is a cord (Z or other suitable flexible connection attached to the bridle (Z' on the frame. On the upper end of this cord is a pulley f, through which is rove a cord f, with its ends fast to the jacks F and F, respectively. Each frame is connected underneath in a similar manner to the lower arms of said jacks.

The pile or loop thread G is led from a spoolH on the rear of the loom over aspringtension bar 9 down in front of the harnesses and through the eye a in the looper or carrier E. Thence it runs through the reed R to the ground fabric, to which it is secured. By means of the looper or carrier this thread is transferred alternately from one side of the loop-wireC to the other side and bound down by the passing of the shuttle over it. This thread is thus securely woven into the body of the fabric. The loops being formed over the wire, they are carried down by the beating up of the reciprocating reed R to the small end of said wire, where the loop is drawn to the proper size. This sequence of motion is repeatedly made, and a series of loops of the pile-warp a are formed over each wire 0, which loops are drawn off of the front end of the wires as the cloth J is drawn forward over the breast-beam S by the takeup motion. (Not shown.) Any number of flattened wires C and corresponding loopthreads G may be used either in groups or otherwise, and any number of harnesses or shuttles may be employed, according to the style of goods desired. Only enough of the loom is shown to illustrate the operation of my invention.

The mechanism for operating the different parts is not shown nor described, as they are all well known, and no particular way is claimed. Any of the several varieties may be employed that may upon trial be found advisable.

The operation of my device is further explained as follows: The flat loop-forming wires 0 are supported and fixed on a rod 0 at one end and extend forward through the reed with their front end (over which the loop is drawn) resting on the cloth. The flexible looper or carrier above described is shown as being connected to the ordinary heddleframes,the heddles having been removed from these two frames, as said frames are used exclusively for operating these carriers. In the dobby-head shown I use two jack-levers to operate each of the two heddle-frames, each frame being drawn both up and down by the movement of the jack-levers by being connected, as shown, from both the top and bottom to each arm of said jaclelevers. These connections are attached by each end of a flexible cord to each arm of two jack-levers, with the bight of said cord engaging a pulley held on the end of strap leading from one of the harness-frames. In operating these jacklevers thus connected by holding one jack up and letting one down, the frame being then in its center position, and when both jacks are either up or down the frames are in a corresponding position. The loop-thread is led from a spool on the rear of the loom over a tension-bar, carried down in front of the harness, threaded through the eye of the carrier, and led through the reed to the ground-warp, into which it is secured by the laying of the weft-threads. By properly pegging the links of the dobby-chain this pile-thread may be held up on top of the wire any number of picks, thus making any desired distance between the loops, or the thread may be drawn down on each side of the wire and held as long as desired, in which position the loop-thread lies on the back of the web, or this thread may be carried up and down on the same side of the wire, thus forming a plain weave. It will be observed that by the use of my device only two harnesses are required to weave any pattern, while by the old method three or more are employed.

By running the loop-threads in front of the harnesses the work is much more accessible and easier to operate. This arrangement also causes less friction and wear than by the old method, where these threads had to be passed through the heddles. One very important feature is my carriers remain in their place between the warp-threads and are sure to work without catching and becoming easily destroyed, as has heretofore been the case by the use of the old method in doup-weaving. The wear of these carriers is reduced to the minimum in working back and forth over the loop-wires by the tension of the loop-threads which engage them.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

1. In a loom for weaving pile fabric, a flexible carrier, a loop-former, means for automatically reciprocating said carrier over said loop-former to carry the pile-thread, substantially as described.
