V UNITED STATES THEODORE J. GARISIO, OF ALLEN'LOWN, PENNSYLVANIA.

DOUP.

' 7 Application filed. April 11, 1925. Serial'No. 22,351.

To all whom it may concern:

Be it known that I, THEODORE J. GAnisio,

Pennsylvania, have invented certain new,

and useful Improvements in Doups; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to doups, which may be used in the manner of my prior Patent- No. 819,420 of May 1, 1906, for making centre selvages on piece goods, and also for making lines of so-called hemstitching or fagoting along the length of the goods, there being as many doups used as there are to be longitudinal rows of hemstitching or fagoting across the width of the goods.

This is mostly done in silk piece goods, and forms longitudinal stripes, the design of which can be varied by including a greater or less number of warp threads, as well as a greater or less number of weft threads in each fagot thread loop.

In fine goods, such as silk, the wire of the doup must be of very small gauge and the eye in the fagot thread carrier must also be small; and there is apt to be a hanging or catching of the warp threads in the angle between the fagot thread eye and the lifter for the carrier. This I have avoided. It is also noticed that the sinuous fagot thread at times feeds too fast, and irregularly, or hangs on the supply spool so that it often breaks, and I have provided means that prevents this by releasing the thread from the spool say a fraction of aturn, so as to allow the fagot thread to feed at will without too great restraint, so that there will be no. danger of this fine thread breaking as it alternately passes through the shed first on one side and then on the other side of a set of warp threads.

Referring to the drawings, in which like parts are similarly designated: Figure 1 shows a vertical transverse section of so much of a silk loom as will be necessary to an understanding of my invention, with my attachment applied thereto.

Fig. 2 is a side View of the doup, about one-half the size. Fig. 3 is an enlarged view of the upper end of the fagot thread carrier, illustrating more clearly the lower bent ends of the lifters.

Referring to Figure 1, I have shown a portion of a loom in which the heddle frames 5, any number of which may be used, carry the usual heddles 6. Each heddle frame 5 is connected to a lifter cord 7 that goes to the dobby or the jacquard, as the case may be. The frames are retracted by springs 8. 9 is the goods beam, 10 the batten, 11 the reed, 12 the warp, 13 the warp guide and 14: the warp beam, all of usual construction and well known arrangement.

' The loom is a top shed loom, although an open shed or a bottom shed loom may be fitted with my attachment. i

The fagot thread carrier 15 is made of a length of wire and has a very small eye 16 at the top of a long loop 17 that is substantially symmetrical to a longitudinal axis of the loop. The eye is turned downward toward the interior of the loop. The upper part of this loop 17 is more ovate or less tapering than the lower part, the two ends of the wire are then twisted together at 18 below the loop, and one of these end terminals below the twisted portion, terminates in an eye 19. The eye 19 is connected to a retracting spring 20 or a lingo, as desired.

'The length of the loop 20 must besuch when passing through the warp during the making of the shed and while supporting the fagot thread in its upper positionthat the warp threads shall, preferably, not rub over the twisted shank 18 of the loop.

The loop has two

lifters

20 and 21, each also consisting of asingle wire having a loop 22 at its lower end, the ends of the wires being then twisted together to form a shank, andterminating in an eye 23. This eye 23 is connected to a cord 24 going to the jacquard or dobby.

It will be noted that each lifter loop 22 is bent at anangle at its lower end at 25, so that when the lifter is raised the lower bent end 25 (Fig. 3) rests in the angle between the fagot thread eye and that side of the carrier loop to which the lifter is connected. This allows the body of the lifter to hang vvertically and the fagot carrier also hang vertically without formingan acute angle the carrier on the other side of the group between the top of the fagot thread eye and the lifter loop 22 that can catch a silk warp therein and cause it to break as the carrier is lifted through the warp. This permits the use of my device with fine silks and other sheer fabrics.

The fagot thread 26, Fig. 1, may feed irregularly, notwithstanding that it is pro vided with a tensioning weight 27 consisting, in my construction, of a small block of wood. This block of wood has a vertical slot 27 and is mounted to slide on a stapleshaped wire guide 28. The weight carries a pigtail thread guide 29. Said guide 28 is driven into a frame 80 consisting of an angle-shaped piece of wood provided with a. hook-shaped piece of iron 31 screwed through one leg to the rear edge of the vertical shank of the frame 30.

A set-screw 32 passes through the other, free, shank of the hook and serves to fasten the frame 30 in any position transversely of the loom on a bar 33 on the back of the loom.

A pin 34 is secured to the horizontal leg of the frame 30, and carries the spool 35 for the fagot thread. This spool is free to rotate and is held on its pin 34 by a cotter pin 36.

Projecting from the spool, preferably from the head adjacent the frame 30, are pins 37, one or more of which may be used, according to requirements.

Mounted on a screw 38 is a lever 39 of wire, having a horizontal stop portion 40 projecting into the path of the pins 37, and the front end of this lever is formed as a hook 41 passing through the staple guide 23 which limits the upward movement of the lever. The lever rests on pigtail thread guide 42.

There is a t-hird-pigtail 43 at the front of the frame 30.

The sliding weight 27 is chosen for he lightest thread, but may be used with heavier thread, and for this purpose an eye 44 is screwed into the bottom of the block 27 on which may be hung a lingo 45.

The operation is as follows:

Assume that a group of two or more warp threads 12 are to be crossed by the fagot thread 26. These warp threads pass between the two lifters. 20 and 21, and the fagot thread is passed from spool 35 through the

pigtails

42, 29 and 43 in succession, the eye 16 of the lifter and the reed to the goods beam. After a given number of weft threads have been inserted in the warp, the carrier 15 is raised through the warp by one of the lifters, say 20, on one side of the chosen group of warp threads, then additional weft t-l'ireads are inserted and the lifter is lowered. The spring 20 pulls the lifter below the warp and the lifter 21 raises of warp threads; a number of weft threads are again inserted in the warp, the lifter 21 is lowered, the carrier 15 remains below the warp until more weft threads are inserted, and the operations are repeated.

In this manner the fagot thread forms a. sinuous weave alternately from right to left and vice versa across the warp threads, including both warp and weft threads.

The pattern is varied by varying the number of warp threads included in the group, and by varying the number of weft threads inserted in the warp between each crossing of the fagot thread.

There are as many doup mechanisms used as there are longitudinal rows of fagoting in the width of fabric.

For making a centre selvage on a broad silk loom only two such mechanism may be used.

In case the fagot thread does not feed well, and to prevent the fagot thread from feeding too fast by reason of the tension thereon during the crossing of the fagotthread, and as this thread is used, the spool rotates until a. pin 37 strikes the stop 40 and is held thereby, the weight 27 then rises until it strikes the hook 41, lifts the wire lever 39 from support 42, releases pin 37, and allows (in the particular structure shown) the spool to make a half turn. The release of the spool permits the weight 27 to drop and the lever to return to its checking position supported by the shank of pigtail 42.

It will be understood that various modi fieations may be made in the construction without changing the nature of the invention. 7
