LOOM FOR CROSS-WEAVING.

SPECIFICATION forming part of Letters Patent No. 642,359, dated January 30, 1900.

Application filed May 25 1899- To all whom it may concern.-

Be it known that I, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Looms for Cross- Weaving, of which the following is a specification. 7

My invention relates to certain improvements in the construction, arrangement, and mode of operation of theseveral parts of a loom for cross-weaving, whereby the loom will be capable of weaving a number of different patterns by very simple manipulation of the heddles, the structure comprising a main heddle and a plurality of auxiliary heddles arranged one above the other at an angle to the main heddle and comprising needle-bars engaging each other, the said needle-bars being provided with banks of needles extended forwardly with their eyes in close proximity to the main heddle.

The structure further comprises an improved means for imparting to the auxiliary heddles their simultaneous vertical reciprocating movements and their independent lateral reciprocating movements.

The object of my invention in providing the above-described structure is to enable the auxiliary heddles to be moved laterally independently of each other, the amount of lateral movement imparted to each of the auxiliary heddles being reduced to a minimum, while bringing the eyes of the needles in close proximity to the main heddle.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a vertical sect-ion taken from front to rear through a loom embodying my invention. Fig. 2 is a transverse vertical section taken in the plane of the line 2 20f Fig. 1. Fig. 3 is a partial transverse horizontal section taken in the plane of the line 3 3 of Fig. 2. Fig. 4 represents several forms of Weave which are capable of being produced by this loom, and Fig. 5 represents in detail a modified form of support for the auxiliary heddles. While I have set forth certain forms of weave which my improved loom is capable of producing, I do not claim the same herein, as they form the subject-matter of three applica- Serial No. 718,221. (No model.)

tions filed by me on the 22d day of May, 1899, their serial numbers being 717,728, 717,729, and 717,730, respectively. I have also set forth certain features of construction for the clear understanding of my present invention, which are not claimed herein, as they form a part of the subject-matter of a pending application filed by me on the 31st day of May, 1899, the serial number being 718,926.

The side frames of the loom are denoted by A, and mounted therein in suitable bearings are the slay-beam-operating shaft B and the cam-carrying shaft C. The slay-beam is denoted by D, and it is connected with the operating-shaft B by suitable connecting-rods b; The slay-beam is of the usual construction, carrying reeds cl, through which the threads of the warp pass. The warp-supplying roller is denoted by E, and it is mounted, as usual, at the rear of the loom between the side frames A. V The shafts B and C are driven by any suitable mechanism. (Not shown herein.)

The weft-supplying mechanism has been entirely omitted in the accompanying drawings, as it is thought that it is unnecessary to the clear understanding of my invention, which relates more particularly to the warp mechanism.

The main heddle is denoted by F, and it is guided in its upward and downward movements by means of suitable sleeves f f at its sides, which sleeves surround a pair of vertical guide-rods G G, which are mounted in suitable lower and upper bearings g 9', so as to rock in the said bearings. The main heddle F is provided with alternating reeds and needles, the reeds extending between the upper cross-bar f and lower cross-bar f 3 of the heddle and the needles projecting downwardly from the upper cross-bar f to a point about half-way between the two cross-bars, the heads of the said needles being provided with suitable eyes for the passage therethrough of certain of the warp-threads.

The auxiliary heddles are denoted by H and I, respectively, and they comprise an upper needle -bar h, from which extend forwardly into close proximity to the main heddle F a bank of needles h and a lower needle-bar i, from which projects forwardly to a point in proximity to the main heddle F immediately below the upper bank of needles h a lowerbank of needlesi. The upper and lower needle-bars of the auxiliary heddles are spaced apart a sufficient distance to 'permit the two groups of warp to pass between them and from thence through the eyes of their respective banks of needles, so that the two heddles may be moved laterally with respect to each other without causing their respective warps to interfere with each other.

The lower needle-bar z' is provided at its end at the right side of the loom with a forwardly-extended arm t the free end of which is secured to a carriage K, which has a free vertically-sliding movement along a supplemental gnide-rod J, which is carried in the free ends of a pair of rearwardly-extended arms j 7' fixed to rock with the vertical guide-rod G.

The needle-bar h is provided at one end in the present instance the end at the left side of the loomwith a forwardly-extended arm 71?, the free end of which is secured to a carriage K, which has a free vertically-sliding movement along a supplemental guiderod J, which is secured in the free ends of a pair of rearwardly-extended armsjj, fixed to rock with the vertical guide-rod G.

The right end of the upper bar his supported by and has a free sliding engagement with the right end of the lower bar 2' in the following manner: The right end of the bar It has a tongue k which slides through a loop 2' in the right end of the lower bar 2', which loop is formed in the rear end of the arm 7?, fixed to the bar i. The left end of the lower bar '5 is supported by and has a free sliding engagement with the left end of the upper bar It in the following manner: The left end of the bar 1' is provided with a loop "6 through which slides a tongue 72 on the left end of the bar h, the outer end of the said tongue being rigidly secured in the rear end of the arm 77.

The auxiliary heddles H and I are caused to be independently moved laterally for causing the threads which they carry to cross the threads carried by the main heddle and pass first on one side and then on the other side of the said main-heddle warp-threads by the following mechanism: The left main guide-rod G is rocked, therebyimpartingalateral movement to the upper auxiliary heddle H by means of a horizontally-swinging lever L, which is hinged at its rear end to a cross-bar a, of the frame and which has at its forward or free end a pin-and-slot connection with a rearwardly-extended arm g fixed to the said rod G. This lever L is moved back and forth by means of a cam c on the shaft (3. The right vertical guide-rod G is rocked, thereby imparting a lateral, movement to the lower auxiliary heddle I by means of a horizontallyswinging lever L, which is hinged at its rear end to the cross-bar a of the frame, the forward or free end of the said lever having a pin-and-slot connection with a rearwardlyextended arm 9 fixed to the guide-rod G. This lever L is swung laterally by means of acam 0, carried by the shaft 0 and cooperating with the pin on the said lever.

The auxiliary-heddle frame comprises an upper cross-bar M, a lower cross-bar M, and a plurality of vertical spacing-bars M rigidly connecting the upper cross-bar with the lower cross-bar. The upper cross-bar M has link connections m with the upper ends of the vertically-sliding carriages K K, and the lower cross-bar M has similar link connections m with the lower ends of the said carriages, so that when the auxiliary-heddle frame is reciprocated vertically it will reciprocate the auxiliary heddles H and I vertically.

In the form shown in Figs. 1, 2, and 3 auxiliaryheddles are supported at their ends by means of flexible connections N N, leading from the vertical spacing-bars M one into engagement with -the needle-bar h and the other into engagement with the needle-bar i.

In the accompanying drawings I have shown the means for imparting alternating vertical reciprocating movements to the main heddle and the auxiliary heddles, as follows: Flexible connections 0 lead from the crossbar M of the auxiliary-heddle frame upwardly around pulleys 0, carried by one of the crossbeams a of the loom-frame and from thence downwardly into engagement with the upper cross-bar f 2 of the main heddle F. The lower cross-bar M of the auxiliary-heddle frame has a connection 19 with the free end of a tappet P, hinged at its rear end on a cross-rod 10 extending across the frame. This tappet P is operated by a cam c on the cam-shaft C, which cam in the present instance engages an antifriction-roller p carried by the said tappet. Retracting-springs Q extend from the lower oross-bar f on the main heddle F down into engagement with a cross-beam a of the loom-frame, which springs tend to draw the main heddle downward, and thereby the auxiliary heddles upward, thus holding the tappet Pat all times in engagement with its controlling-cam c While I have shown the auxiliary heddles as supported by flexible connections at their rear ends leading to the auxiliaryheddle frame, it is to be understood that the auxiliary heddles might be supported in many other ways. In Fig. 5 I have shown another way of supporting the rear ends of the said auxiliary heddles by providing brackets M one only of which is shown in the said figure, which brackets are secured to the vertical spacing-bars M and project forwardly a sufficient distance to permit the lower needle-bar i to rest thereon.

It is to be understood that any suitable Jacquard mechanism may be applied to my improved loom for controlling the times of the vertical reciprocating movements of the main and auxiliary heddles and also controlling the times of the independent lateral movements of the auxiliary heddles, so as to permit the loom to weave various patterns. As the said J aoquard mechanism is well known, I have not attempted to illustrate the same in connection with the drawings, but have shown a simple and effective device capable of imparting to the said heddles their independent lateral movements.

By mounting the banks of needles of the auxiliary heddles at an angle to the bank of needlesin the main heddle, one directly above the other, I am enabled to bring the eyes in the free ends of both of the banks of auxiliary needles in close proximity to the main heddle, which arrangement I have hitherto been unable to accomplish. Furthermore, I am enabled to lead the warp-threads for the auxiliary heddles between the two needlebars and from thence directly to their particular bank of needles, thus doing away with a great amount of chafing caused by crossing the said warp-threads, as is now done by mounting the auxiliary heddles parallel to the main heddle.

The weaves illustrated in the accompanying drawings represent some of the patterns which may be woven by the structure hereinbefore described.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts Without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein set forth; but

What I claim is- 1. In a loom, a main heddle, a plurality of auxiliary heddles arranged one above another at an angle to the main heddle, means for imparting Vertical reciprocating movements to the main and auxiliary heddles and means for imparting independent lateral reciprocating movements to the auxiliary heddles, substantially as set forth.
