LOOM FOB WEAVING CANE, &o.

Application filed March 16, 1911.

T 0 all whom it may concern:

Be it known that I, 'Tiiowms l. WALsH, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Looms for \Veaving Cane, &c., of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention is a loom specially adapted to weaving coarse fabrics such as are pro duced with cane, willow, wire, etc.

Besides providing weaving mechanism capable of handling the coarse, heavy, stiff strands mentioned. one object of my invention is to provide means for accomplishing the weaving rapidly, means having a considerable range of pattern variety, means for facilitating the case of handling the warp strands whereby. for instance, in the shedding operation, they are subjected to a minimum bending strain, and moreover such bending strain as is necessary is an easy strain and not tense.

The constructional details of the preferred embodiment of my invention herein contained will appear more fully from the following description, taken in connection with the accompanying drawings, in which I have shown a preferred embodiment of the invention.

In the drawings, Figure 1 is a central ver tical longitudinal sectional view of my preferred loom: Fig. I is a detail in side elevation of one of the pattern pins and spacers; Fig. 2 is a view thereof in front elevation; Fig. 3 is a righthand side elevation; Figs. eland 5 are enlarged fragmentary views in top plan and front elevation respectively of the two filling carriers or needles preferably used in the loom, shown in their cooperating position at the middle of the loom or end of their inner throw; Fig. (i is a sectional view showing the pin-wheel drive or lcneva movement in side elevation; Figs. 7 and 8 are devclopn'ients of the pe riphery of the respective cams for operating the needles, the former for operating the supply needle and the latter for operating the nipper needle. Fig. 9 is a vertical transverse sectional view showing the selvage mechanism in front elevation; Fig. 10 is an enlarged section of the weave at the selvage; Kg. 11 is a arms-sectional detail on the line Patented Dec. 1, 1914. Serial No. 614,887.

11-1l, Fig. 9; and Figs. 12 and 13 are diagrammatic viewsshowmg various combinations of arranging the pins of the pattern mechanism for different weaves.

The warp strands 1 (of wire, for instance) pass from a usual source of supply under a stationary rod 2 mounted in suitable loom sides or frames 3, 4 and thence over whip rolls 5 pivoted at 6 in the frame and herein shown as held yieldingly by springs 7, there being as many of these whip rolls as the pattern may require or the convenience of the weaver and goods may demand. From these whip rolls the warp strands pass to the front of-the loom over a usual guiding and supporting device, herein shown for convenience as a breast beam 8, to any desired and suitable kind of take-up mechanism, herein shown as comprising a take-up roll 9, guide roll 10 and winding roll 11, the tram of operating mechanism and actuating devices therefor being of the usual kind and therefore not fully shown and not described.

' At a suitable distance back of the fell 12 is mounted a rotary shaft 1.3 on which is keyed a series of winged plates or wheel like separators 14, spaced apart by spacers 15 to receive and properly position the respective warp strands. Pins 16 extend from the spacers radially of the shaft, said pins being herein shown as having four positions or arranged in four series at equal distances apart to correspond to the four steps or succcssive equal movements of the shaft. It will be understood, however, that this arrangement is shown simply to illustrate the general idea. and that the total rotation of the shaft will be, divided into such a number of steps orseparate movements and the number of series of pins or equivalent devices will be correspondirur v varied to suit the requirements or preferences of the weaver within the scope mi the invention. As the shaft is rotated to the :osition shown, tor instance, in Fig. 1, those pins 16 which are thereby raised into upright position serve to lift those warp strands which are engaged by the upright pins, thus forming a shed. The raised warp strands are lifted by the upright pins from the horizontal level of the remaining warp strands, which level constitutes the lower part of the shed and is the normal position of all the warp strands. As herein shown, the innermost give-away whip roll 5 is engaged by all en ga h v those we. strands which are raised by the upright IS 1 as shown in Fig. 1., and yields when these pins raise said warp strands and if. may be considered that the next whip roll 5) engaged by those warp strands which are controlled by the series of pins which s indicated as extending ap proximately horizontally rearward, Fig. 1,

and the next whip roll engaged by those warp strands which are controlled by the downwardly extending; series of pins 13, F1

1, and theremaining or rearrnost whip r01 as engaged by the warp strands indicated in Fig. 1 as extending approximately horizontally forward from the shaft 13. The pattern. being woven depends upon the position of these pins with reference to the shaft 13 and with reference to each other so that by varying the relative positions of these pins 16, the pattern of the cane weaving may be uli jal. :lv so that a large variety of corni iinutions of diilerent weaves may readily be effected by my loom, and all on the one shaft or in connection with the one shedding and pattern mechanism, as will more fully appear presently-with reference to Figs. 9 and 10. Any suitable driving means for this pattern and shedding mechanism may be provided, being herein shown as comprising a gear 17 on the shaft 13, meshing with a gear 18 secured to a star wheel 19 and loose on a stud 220 projecting from the frame 3. The star wh "fl is driven by engagement with pins 21, 3 of pin wi' "c on a stud 25 and driven by a sprocket to said pin wheel and a chain 27 passing over & sprocket wheel fast on a. cam shaft 29.

The weft or filling strand iii) of wire or the like derived from any suitable source, as a spool 31, Fig. 2, whence it passes between rotary guides or press rolls mounted at the rear cn-zi of a s ationary hradret 33 steeds laterally .rom the i bracket i3 has a. T-tro We 1, in which a s de block Si is mounted to tra el lengthwise. linmovably held in a projecting car of this slide block is a weft carrier or needle 36. This carrier or needle is best shown in Figs. 1 and 5, where it will be seen that it is tubular or provided with hollow interior 3-7 for receiving the eft strand, 30. open or provided with a longitudinal slot at its upper side, preferably extending to within a short distance of the inner end 39 of the carrier or needle 36, said slot 38 being also preferably, although not necessarily, continuous through out its length. At the inner end 39 of the carrier I provide any suitable meanst'or frictionally engaging and clamping the free forward end of ill. filling strand, herein six-own as comprising an upper spring menu ber 4.0 and a lower member 41, the former preferably having downwardly extending ears 12 at its opposite sides so as to maintain the two springs in alineincnt and prevent the cane or weft strand from slipping out sidewise. The inner gripping surfaces of the s 'iring' jaws 10, 41 are preferably providcd with oblique teeth so as to permit free relative movement thereof over the Weft strand in one direction while preventing said movement in the opposite direction. This weft carrier or needle is actuated by any convenient n'icchanisni, being herein shown as coinpri lug a lever 43 having a pin and slotconnection 41 with the block 34 of said carrier at one end and pivoted at 15 to a bracket 16 of the frame 3 at the other end, and actuated by a link 47 and cam lever 48 whose cam roll 49 engages a cam 50 on the cam shaft 29. At the opposite side of the loom, a somewhat similar hollow Weftcarrier or needle 51 is provided, secured in u block ()2 which travels in :r lateral bracket the same in construction as the bracket 33, said block being actuated by a lever 54, link 55 and cam lever 56 whose roll 57 traw els in a path cam 58, all substantially the same as the corresponding parts already described at the opposite side of the loom. The carrier or needle 51 differs from the carrier or needle 36 in having provision for receiving the weft strand from the needle 36, the mechanism provided for this purpose being herein shown as comprising relatively heavyupper and lower spring prws 60 under constant tendency to close. Any snitable means is pi-m lil jil for maintaining these jaws .39. 60 opt-u when going inwardly or toward the left, Fig. 5 and permitting them to be closed when going toward the right, Fig. :2, said means being herein shown as consisting of a cam or spreader 61 pivoted at 62 to the lower jaw 60 and having its upper cam edge in position to en go a pin 63 projecting from theupper jaw 59. Preferably the cam edge of the spreader 61 is shaped adjacent its forward end 64 to be entirely out of engagement. with. the pin 63 when in the position shown in Fig. 5 so as to permit the gripping jaws 59, 60 to exert their extreme gripping tension or pressure on the Weft strand when required to J,

positively to maintain the jaws open so as not to be closed accidentally by vibration or accidental movement. A pin 66 projects latorally from the spreader 6,1 in position to be engaged by the forward end of a projecting finger 67, herein shown as extending rigidly from the front'end 390f the carrier or finger 36, in position to strike the pin 66 j 'xst as the needle 51 has arrived into position to engage the free end of the weft strand which projects from the jaws 40, 41

of the needle 36. This permits the jaws 59, 60 to close hard upon said free ends so as to hold the weft strand positively as the needle '51 starts back on its return or Weft-pulling movement. A stop or operating lug 68 projects from the bracket 53 in position to engage the pin 66 at the end of the pulling movement of the needle 51 and thereby restore the cam spreader 61 to spreading position with the pin 63 occupyingthe depresslon 65 so as to open the jaws 59, 60 and keep them open during their return movement to the'left, Fig. 2, for another Weft strand. The jaws 40, 41 are made lighter than the jaws 59, 60 because the resistance of the weft strands 30 tends continually to pull them closed on the inner or drawing movement, Whereas the resistance of said weft strand to the jaws 59, G0 on the drawing movement thereof tends to open said jaws, thus requiring that said jaws 59, 60 shall 'be heavier than the jaws 40, 41.

To sever each transverse strand of filling as it is laid, I preferably provide at the end of the shaft 13 a rotary shear blade or severing device 69, herein shown as having four teeth or cutting. members corresponding to the step movements and shedding operations of the shaft 13 and parts carried thereby) to cotiperate with an under shear blade pivotally mounted on the same shaft 13 and having a rearwardly extending end 71 actuated by a rod or link 72 and cam lever 73 pivoted at 74 to the frame side 3 and having its roll 75 actuated by a path cam 76 on the cam shaft 29.

Preferably the beating-up operation is accomplished in connection with the rotation of the shaft 13 and by means carried thereby. Said means, as herein shown in this preferred embodiment of the invention,'consists of wings or cam shaped projections 77 projecting from the separators or warp-directing plates 14 and corresponding in number and arrangement to the num ber of series and arrangement of the pins 16, so that as soon as a pick of filling strand has been laid across the loom, the shaft 13 rotates, thereby lowering the shedding pins 16, then in an upright position, and simultaneously turning the upright camwings 77 over forward and downwardly toward the left, Fig. 1,2so as to move the laid strand :of filling gently but positively forward to the fell, the shearing mechanism severing said strand just before the upright wings 77 engage it.

"It will be understood that the driving mechanism of the loom may be of any usual or preferred kind, a gear wheel 78 being herein shown, Fig. as fast on the outer end of the cam shaft 29 and driven by a gear 7.) on a driving shaft 80 actuated by a driving pulley 81 and belt 82-, the whole under the usual control of a shipper lever 83 and shipper 81.

' At some convenient point, herein shown as just below the drive shaft 80, is a shaft 85 provided with cams 86, 87 for actuating the selvageforming mechanisnr used when the loom is making a wire fabric. This mechanism is shown best in Figs. 9 and 11, the salvage being shown in Fig. 10. Pivotally mounted on inwardly projecting brackets 88 are levers 89, 90 connected by a link 91 to operate in unison, and receiving their movement from a lever 92 pivoted intermediately at 93 on the loom side 4 and connected by a rod 94 to an arm 95 fast on a rock shaft 96 provided with a cam lever 97 whose roll 98 travels in the path of the cam 87. The bending devices proper 99 and 100 are operated respectively by the levers 89, 90 with which they have pin and slot connection, being mounted on pivots 101 in slots formed in lateral flanges 103 which extend forward from the brackets 88. Below these upper bending devices 99, 100 are similar lower bending devices 104, 105 mounted on pivots 106 in slots 107 formed in forwardly projecting flanges 108 of lower brackets 109 corresponding in general construction to the brackets 88. These mech anisms are located at some convenient point between the fell and the breast beam, and the laterally extending flanges or'ledges 103 and 108 serve as guides for the opposite edges of the fabric as clearly shown in Figs. 9 and 11, and also serve toimaintain the proper certainty of position of the edge warp strand and cut ends of the filling which are to form theselvage. The lower bending devices 104, 105 are operated in sub stantially the same way as the upper ones by levers 110, 111 connected by a link 112' and receiving movement from a rod 113 and crank lever 114 pivoted at 115 whose roll 116 travels in the path of the cam 86. The two actuating cams 86, 87 are timed so as to actuate the upper bending devices on one pick and the lower bending devices on the other pick. Each upper bending device is provided with a relatively long bending finger 117 and a short bending finger or clenching finger .118, and each lower bending device is provided with a similar long bending finger 119 and short bending finger or clenchiug member 120. The slots 102, 107 are wide enough for two picks. 2'. a. they have a width to accommodate both the bending finger and the clenching finger of the bending devices, so that when a weft strand comes into alinement with said slots and with the long fingers or preliminary bending fingers 117, 119, the result is that said strand is engaged by one of said fingers, being engaged for instance by the finger 117 if the end of the strand should be bent downwardly to form the selvage, and by the finger 119 if said lie end should be bent upwardly to form the selvage. For instance, in Fig, 10, .l. have shown in dotted lines a, strand. as having been engaged by the finger lit and bent upwardly from the full-line position to the dotted-line position 121 and then engaged by the clenching linger 3.3.8 ef theetlier bending device on the next pick and clenched into a-tight s'elvnge as shown in In other words, each long i1? gives the adjacent cut end of the weft strand e oresov from the left tow V liminary bend toward the opposite bending device .to a suibcient extent to permit short finger of said oppositebending device toengagc this partially bent wire-end on the next swingingqmovement of said opposite short -finger and thereby crimp down or clench thepartially bent end to its completely bent position. This forms the selvage and makes. a smooth, neat, strong edge. The bending of the Wires is ac-eomplished alternately in opposite directions, as; re qmred by their position alternately above and below'the outermost warp strand or selvage wire,snd saidelternate wrapping 31 position between the separators onpositioning plate-s l-i and err giiging the.respectivewhip rolls 5, and the iveft strand being in. place'in the left hand weft carr er 36, the shaft 113 rotates over forward so es'to' bring one series of lift .ing pins 16 into upright position as shown in-Fig. 1;..thereby correspomlingly lifting those Warp strands which pattern (22125; for according to the pnri icula Wea e or weaves being woven in any W611 fabric.

At the same instant, the carriers retreat from each other, the strand of filling beln now iinmovably engaged by the righthan car-z rier, which pulls it freely forward, the jaws 4-0, 41 yielding readily to permit this relatire forward movement'of the filling strand with relation to the carrier 36 'as the latter moves beck to its or'g'inal position, at the extreme left side of the loom.- lrVhen the tnjo ca rriers have this retreated to their original position at the opposite sides of the loom gmd the filling strand has been laid: in proper weaving position, the shear blade 70 begins to 'move' lipward under theinfi-uence of its actuating mechanism71- 76,

and the shaft 13 starts its nextste by step movement or rotary impulse, the rst eflect of which is to bring the overhanging knife or shear blade 69 down upon the'strand oflaid' filling as the under blade 70 ,rises against the under side of said strand, thereby severing the strand (wire, cane will'ow, .or otherrelatively intractable Weft); The

further rotation of the shaft 13 immediately brings the cam surfaces of the upright beat ing up wings 77 into engagement with the laid strand of filling, which is 'thereby beaten up to thefell at 12. Meanwhile the same rotary movement of the shaft 131138? lowered the pins 16. thereby restoring the raised warp strands to their normal horizontel-position, where they are maintained taut series of warp'strand s is raised to shed-posi tion by the next or "previouslyxearwardly mately forward horizontal position. soon, as this next selection of warp strands roll,- and the next 4 has been raised bysaid pins to form the next 1 shed. the carriers 36. 51 again she for: ward. the latter grabbing the free end of the strand of filling from the former as the two carriers reach the end oftheir inward movement, and then the carriers at once separate back again aw ay from'each other.

sidering the relatively stifl unmanageable character of the material being woven. By having the needles or carriers arran d to move to the center of the goods an back again, I accomplish a number of advantages. In the first place, the needles themselves are thereby shorter than if they had to move the entire width of the loom and are consequently under better control and the loom is in better balance or shape and capable of more rapid and accurate work and adapted to handle heavier fabrics. In the second place, the weaving is increased at least double, inasmuch as the complete laying of one strand of filling is accomplished in the time required for one needle to move halfway across the loom and back again, as distinguished from requiring the time for a needle to move twice that distance, and moreover the needle-operating mechanisms at both sides 'of the loom operate simultaneously and in opposition to each other,

and as the movements are relatively short it is feasible to run the loom at relatively high speed. As already stated, one of the principal objects of my invention is to make it feasible to weave these comparatively unmanageable materials at' relatively high speed, and, besides the features already mentioned as cooperating to this end, another important means for increasing the practicable speed of such weaving residesthe beating-up and the shedding movements in one mechanism wh ch is in combining Instead of the ordinary lav and harness mechanism, the 'single'rotarv movementof the shaft 13 simultaneously heats up the weft by the cain wings 77 of said shaft) and lowers the shed (by the pins 16 of said shaft), and at the same time the same rotary movement shears ofi' the end of the wire (by the cooperating blades 69, and furthermore the same rotary movement instantly raises the next shed hv the next set of pins 16 which come up lust as the laid wct't strand has reached the full. In other words. my mechanism succeeds in a complishing a rapid Weaving movement of such diflicult materials as Wire, cane, etc.. notwithstanding the necessity for strong positive controlling movements thrmlghout all portions of each weaving movement of the loom. The pins 16 (which are preferably although not necessarily formed separately from the spacers 15 and are rectangular in cross section and removablv secured adjacent their free ends to the adjacent separators 14, as by pins 126 which enter holes .127 therein) are provided 'for the double purpose of affording a strong positive and quick, yet easy or gradual shedding movement, and at the same time making it possible to produce all the usual varicty of WQZH'ES commonly desired in cane fabrics, etc.. and in Figs. 12 and 13 I ha 1e preferably rotary.

Patent is:

illustrated some of the various arrangements of weaves possible with this mechanism, notwithstandin that such difficult material is being han ed as, say, cane. Refer-ring to said Figs. 12 and 13, I have indicated at 128 a border of plain weave, followed by a two-and-two twill 129, a thn eand-one twill 130, a coarse-basket weave 131, a mixed or granite weave 132, and a fine basket weave 133. In Fig. 13 I have shown varieties of herringbone effects, a simple, single-point herringbone 134, next to which is a double, blunt-pointed herringbone 135 and then a single, blunt-pointed herringbone 136. These varieties are illustrative merely, to indicate to some extent'the capacity of the pin 16 kind of shedding-pattern control which, while providing the positive and yet gentle and strong operation required, yet affords a wide range of variation. quarters as shown, but this also may be varied. It will be understood that all the weaves shown for instance in Fig. 12, take place simultaneously across the loom and are accomplished in four picks or one revolution of the shaft 13, these variations being due simply to the arrangement of the pins 16, a pin being indicated by each x.

One object and in fact necessity of the shaft-and-pin shedding mechanism is that thereby it becomes possible to have the shedding mechanismclose to the feil and the heavy warpstrands have a very short lift,- and this lift is at a uniform height for all the strands, so that, notwithstanding the kind of fabric that is being woven, the danger of breaking the strands is practically eliminated. But I do not herein make claim, broadly considered, to the provision, in connection with warp-supporting means, of a series of separators spaced apart to enter between the warp strands and hold them in position to be shedded, and rotary shedding means extending between the separators for lifting and lowering said warp strands in desired order for the shedding operation. as this combination is duly claimed in my Patent N0. 1,067,205, of July 8, 1913.

Without enumerating at this point those features which I consider broadly novel, I, deem it proper to point out that it will he understood from-the claims that in a number of impprtant respects certain features of my invention are of a broadly novel and pion er character .for this class of weaving.
