WILLIAM H. HARTLEY, OF FALL RIVER, MASSACHUSETTS; EMILY HARTLEY ADMINIS- TRATRIX 0F SAID WILLIAIAI H. HARTLEY, DECEASED.

HEDDLE FOR LOUD/IS.

Application filed. April 22 To all whom it may concern:

Be it known that I, LLIAM II. HARTLEY, a citizen of the United States of America, residing at Fall River, in the county of Bristol, State of Massachusetts, have invented certain new and useful Improvements in Heddles for Looms.

The objects of my invention are, to increase the capacity of a dobby machine; to produce various designs and patterns, one, two, three, or more times its present lrnown capacity, without increasing the number of shafts; to produce designs and patterns heretofore considered impossible, except with a jacquard machine; to weave designs on any specified number of shafts, with the patterns placed in various different positions; or with. the patterns themselves, each of a different character, and each one woven independently of the other, from the same shafts provided with my said improvements, thus enabling a dobby machine to produce more varied and much larger designs and patterns at a greatly reduced cost, as compared with the jacquard machine.

Ihe particular construction employed by me, and the best embodiment of my invention now known to me, is shown in the following drawings, in which:

Figure 1 represents a des'gn showing different weaves, and a drawing-in plan for said design; Fig. 2 represents another design, the patterns being different, and a drawing-in plan for said latter design; Fig. 3 represents my new heddles and a warp-thread therethrougl'i; all being in normal position; Fig.4 represents the warp-thread operated by one heddle for one kind of weave, the other heddle being idle; While Fig. .5 represents the warp-thread operated by the other heddle for another kind of weave, the first heddle being idle.

The principal feature of my invention re sides in means whereby a warp thread may be controlled by two or more shafts, said means being illustrated in digs. 3, 4 and 5. A wire heddle c, has a long eye or slot (Z, on one side of which is attached a ring 6; through this slot and ring, a thread "i is drawn. Attached to this ring is a cord 9, which is passed through a lopp 72 formed on the lower part of the wire heddle 0. Fixed to this cord is a lingo or small weight 7'. While I have described and illustrated the particular formtjof this feature of my inven- Sp eeifieation of Letters Patent.

tion, as constructed by and used by me, it is to be understood, that this feature may be embodied in other suitable material and in other forms. For example, the weighted means for controlling the movements of the thread relatively to its heddle, and its attachment to the thread may be varied; provided always that the heddle does not interfere with the up and down movements of the thread relatively to the heddle, and also that the thread always tends to move toward the bottom of the heddle.

To make use of my invention, the warp threads to be employed, are drawn in according to what I term a double system of drawing in, because every thread, as T, in the warp, which is to talre part in forming the pattern, must be drawn in through two heddles, as c, 0, each heddle being on a shaft, as m or a. The long eye or slot (Z in each of "hose heddles, allows the thread to work freely in the eye of the slot, as in Figs. 4 and 5, so that the said thread 'I can be controlled and worked by either one of the said two shafts m, a, without interference with the other; thus every thread taking part in forming the pattern in the fabric, must be drawn through two heddles on two separate shafts, both heddles having the long eye or slot. To draw in a thread, as 'I, Fig. 3, it is drawn through the ring 6, and slot 61, of the heddle c, on the shaft m, and then through the ring 6 and slot d on the heddle c on the shaft a. When so drawn in, the thread is under the control or regulation of weights or lingoes j of the heddles c, c, and under some circumstances the use of the two weights is necessary; but under others, one weight for each thread is enough. In connection with the designs shown in Figs. 1 and 2, one weight for each thread is suflicient.

In I i g. 1, I have shown how, with my new attachment, and method of drawing in the warp threads, the same pattern may be woven in two entirely different positions, and still be woven by the same shafts. In this design, the first ten threads A would be woven by shafts 1, and 2, plan C, not provided with my invention, because they are weaving plain. The threads, numbers 11 to inclusive, section B, which are to form pattern 1 of the design and fabric, are drawn first through the long thread slots on the heddles on the specified number of shafts, viz. 18, and numbered 3 to 20 inclusive,

erases through the heddle on shaft number 3, provided with l he slot, but the ring without and weight. In the same way thread in ber 12 would be first drawn through the heddle having said slot, ring and we ght on shaft the" car ied forward, and drav-in through the heddle irovided with 0 long slot O1 att i-hnient, on sha: ber This nethod or system of dra in the "w. p threads woiiild be continued with all the threads from number 11 to inclusive; thus, in this case, ev ry thre from number 11 to 41-6, of my desig 1. section B,would beoo." oiled by shafts, rnbered 3 to 20 inclusive i .th only the long slot of sr d attachment, and also by shafts nun l provided with said attachn'ieiwere 21,

so th V J 1 we to weave attcrn 1. of the design, f woulo opie threads or 16 oesi the fanthread is regui cord, and weig it of its shafts. the two i L rect line with the L shafts i'iurnbers '21 with said attachment; is sh! to 20 inclusive, reinr g operative, when the thrds are c ironed to weave a plaitii or other weave, by the heddles 2 22, having my attachment.

In my design 1, l have shown that not only patterns in reverse positions, patterns 1 and 2, but also pattern in different positions, can be woven by the same given shafts when use is made of said attachment, and the threads are drawn in as described; whereas by any other heretofore Known means, a separate and different series of shafts would e required to weave each pattern. Thus, to weave pattern 1, there would be required 18 shafts; lso another separate series of 18 shafts for pattern 2; and also four separate shafts to produce the plain weave; a total of ll} shafts. The same, or better results are inclusive, which are the same shafts em ployed to weave pattern 1, section B, Fig. 1. These threads 56 to inclusive are also con trolled by shafts 23, 24, section C. To draw in the latter part of the design, thread 56, section B, is first dr wn through the heddle on shaft 23, having my attachment, and then carried forward and drawn through the slot in heddle on shaft 3, as before; the slots allowing the thread to be controlled either by shaft 3 or shaft 23, called for by the design, section 3. Thread 57 would be first drawn thr iigh the heddle on 24, and then carried forward drawn through the heddle on shaft 4; and so on with all of the threads up to and. incl shaft 20, and in this way, the

and 22 would be inope tive; whit, when weaving the plain weave, section B, in line with the pattern 1, section B, shafts Z3 and 24 would be operated; wh n weaving the pattern 2 itself, I should op e shafts 3 to 20 inclusive, as in weavingpat "n 1; shafts 21 and 22 being operated at the same time to produce a plain weave in line with the pattern 1, section B. i here the whole design 1, shown in Fig. 1, is to be woven, then shafts 3 to 20 inclusive will weave both of the pat terns; and further, while there is being woven one of the pattern" and so much of the design opposite thereto and plain weave, and does not include the plain wear-re of sections A and A woven by the heddles 1, 2, it is obvious that while the pattern 1 is being woven by the shafts 3 to 20 inclusive, the long thread. slots, in the hcddles on the shafts 3 to 26 inclusive nd through which are drawn all of the i in, section-B, permit the shafts 2S and to moved to weave the plain weave opposite pattern 1., while said shafts 3 to 20 inclusive are wear ing the pattern 1 of the design.

In my design 2, Fig. 2, I have used the same number of shafts drawn in in the same method, as for design 1. By usin 16 plain threads D, l have shown how these plain threads may be increased to any number, called for by the design or fabric to be woven, without increasing the number of shafts.

erases Also, my design 2 shows two entirely different patterns. With any heretofore known method these two patterns could not be produced in woven fabric with less than 38 shafts on a dobby machine. Practically, they would require a jacquard machine for their production.

By the use of my invention, warp threads may be used for fancy weaves and designs for various textile fabrics, such as silks, cottons, woolens, linens, napkins, handherchiefs, tidies, and the like.

Having described my invention, and know ing that it may be embodied in different forms without departing from the spirit thereof, I desire to protect it in the broadest man ner legally possible.

What I claim is 1. In a heddle for a warp thread, means whereby the warp thread may have free but limited up and down movements in relation to the heddle, and means operatively connected to said thread, always tending to over come the upward movements of said thread.

2. In a heddle for a warp thread, means designed to engage the warp thread, and constantly tend to hold the warp thread in its lowest position in relation to its heddle.

3. In a heddle for a warp thread,weighted means to engage said thread, and always tend to hold the warp thread. in its lowest position, in relation to the heddle.

4. In a heddle for a warp thread, means mounted on said hcddle and adapted to receive the warp thread therethrough; cord secured to said means; and a weight suspended from said cord all designed to move the said thread downward relatively to the heddle and to tend to hold it in its lowest relative position.

5. A wire heddle having a tl'u'ead slot, and means mounted on the side of said slot, to engage a warp thread passing through said slot, and move it downward.

6. A wire heddle having a thread slot; a thread ring mounted on the wire side of said slot; and a weight suspended from said ring to tend to hold the thread at the bottom of said slot.

7. A wire heddle having a thread slot; a thread ring mounted on the wire side of said slot; a weight suspended from said ring to tend to hold the thread at the bottom of said slot; and a guide for the weight.

8. A heddle provided with a slot for a warp thread; and a second heddle having a thread slot for said warp thread, and weighted means to engage the said thread, and constantly tend to move it downward and back to its lowest position relative to the heddle, when the thread is raised by the other heddle through which the said thread has been drawn.

9. Two heddles through which a warp thread may be drawn, each heddle having a slot for said thread, whereby the thread may be freely moved by one heddle without interference by the other heddle through which the said thread is drawn; and also having weighted means to engage said thread and constantly tend to move it downward when relatively to its heddle, it is raised by the other of said heddles.

10. A series of heddles to control a series of warp threads, to weave designs of various patterns, each heddle being provided with a thread slot; and a series of heddles to control the same warp threads to weave different ground weaves, each heddle having weighted meansto engage its respective warp thread, and constantly tend to move it back to the bottom of the thread slot, its normal position; all designed so that the same series of threads may be used to produce different patterns and ground weaves in succession.

11. A series of heddles provided with thread slots to control a series of warp threads to weave patterns; a second series of heddles to control a portion of said series of warp threads, so that said portion of warp threads may be employed in weaving a weave different from that of the pattern weave, each her-- dle being provided with weighted means to engage its respective warp thread and constantly tend to hold said thread in its lowest position in relation to its heddle; a third series of heddles to control another portion of said series of warp threads to weave another pattern, each of said heddles being provided with weighted means constantly tending to hold its individual warp thread in its lowest position in relation to its heddle; all being so combined that a pattern weave and a different weave may be simultaneously woven in line.

In testimony whereof I aflix my signature in presence of two witnesses.
