METHOD OF XVEAVING NARROW-WIDTH VJARE AN D MACHINE FOR CARRYING OUT SUCH METHOD.
Application filed April 29, 1926. Serial No. 105,355.
This invention relates to the weaving art in general and more especially to methods of weaving narrow width wares such as braids, tape and the like, and to weaving machines for carrying out such methods.
.a'lmong the objects of the present invention, it is aimed to provide an improved shuttleless loom by means of which it is possible to weave braids or tape of any width up to about six inches.
l t illi braid or tape weaving machines, at-
tnnpts have been made to support the shuttles upon vertically slidable frames by means of which, a heater carried in such frame would beat up the woven portion with every ascent of the frame. l Vith a machine having such vertically movable frame, the shuttles ravcl transversely thereto during the vertical movement of the frame, and on account of the sizes of the shuttles, it would be necessary to give the movable frame a vertical throw of at least siX and a half inches. ()n account of this excessive throw, if the vertical frame was subjected to about one hundred throws a minute, the shuttles would be subjected to excessive wear, quickly begin to rattle, augmenting the already excessive noise accompanying the operation of a loom, and require constant attention and repair of parts. With such looms it has been found impossible to operate the machine wi .h more than one hundred and four throws a minute. To this end, the present invention contemplates the provision of a weaving machine, in which the throw of the vertically moving frame is reduced to about one and a half inches, shuttles dispensed with and replaced by needles, by means of which, the speed of the machine can be increased to operate at least one hundred and thirtyfour throws a minute Without any danger to the working parts due to excessive wear, and wi hout any excessive noise.
lt a further object of the present invention to produce a machine whereby a naximun'i quantity of braid or tape may be produced in a minimum space of time, and at a minimum cost.
it a further object of the present inven on to produce a machine whereby a. e of braid or tape may be prodi l. in which the natural fluiiy surface I the threads is preserved, and at the same time the speed of production increased and the expense of production decreased.
It is still a further object of the present lnvention to produce a braid or web having overhanging loops to form fanciful fringe or edge formations.
It is still another object of the invention to provide a method for producing a web or braid having overhanging loops to form fanciful fringe or edge formations.
And it is still a further object of the present invention to provide a weaving machine for carrying out a method for producing webs or braids having overnanging loops or the like to form fanciful fringe or edge forniations.
These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specific embodiments thereof illustrated in the accompanying drawings, in which Figure 1 is a perspective of the compleie machine with but one of the weaving units set up;

The embodiment illustrated comprises essentially a design controlling mechanism and a weaving mechanism. The design controlling mechanism is operatively mounted in the auxiliary frame 1, and the weaving mechanism is operatively mounted in the main frame 2.
The main frame 2 has two upright end portions 3 and 1 extending to a height of about seven feet in some cases, and which are secured to one another in upright position by suitable tie rods 5, 5, at the bottom and a tie rod 6 at the top, and suitable cross bars which also function as supporting bars for spool supports and the like.
In the frame 2, a secondary frame 7 is mounted to slide vertically. The secondary frame 7 consists essentially of two longitudinally extending angle bars 8, 8, which are connected to one another by the cross bars 9, and end angle bars 9 9, see Fig. 3. The ends of the angle bars 8 are mounted on the bosses 10, of the brackets 11 and 12. The bracket 11 is secured to the vertical rods 13, 13, mounted to slide in the tubular guides 14, 14-, respectively, ecured to the end frame member 3. The bracket 11 is pivotally connected to the link 15 which in turn, as shown in Fig. 1, is eccentrically connected between the disks 16 and 17, the cisk 17 being secured to the shaft 19, and the disk 16 being operatively connected by means not shown to the main shaft 2 1 suit ably mounted in the frame members 3 and 1.
The bosses 10 on which the other end of the secondary frame 7 is mounted, are secured to the bracket 12, (Fig. 2), which is fixed to the vertically slidable rods 32, vertically slidable in the tubular guide mem bers 33, 33, fixed to the frame member 1. The bracket 12, (Fig. 2), similarly to the bracket 11 is pivotally connected to an eccen tric rod or link 3 1 which is eccentrically and pivot-ally connected between the disks and 36, see Fig. 1, which are mounted on alined shafts, not shown, in alinement with shaft 19 in order to insure the simultaneous and same distance of throw of both ends of the secondary frame 7. The shaft of the disk 36 is operatively connected by means, not shown, to the main shaft 24, and timed so that the velocity transmitted to the disks 35 and 36 will be the same as that transmitted to the disks 16 and 17.
In order to relieve the main driving shaft 2 1 of the necessity of carrying the weight of the secondary frame 7 when transmitting vertical reciprocation thereto, there are provided two sets of extension springs 89, 89, d0, 10, the springs 39, 39, connecting the bracket 11, with projections secured to the upper end of the frame member 3 and the springs e0, 40, connecting the bracket 12 with the extensions tl, 41, secured to the upper end of the frame member 1. These springs furthermore assist materially in increasing the speed of the machine, without overloading the motor, not shown.
In order to facilitate turning over the machine by hand, the shaft 42 is suitably secured to the frame 3 and provided with a hand-wheel 43 for the rotation thereof and a bevel gear it provided at the lower end of the shaft 12 in mesh with a bevel gear 4% on the main drive shaft 2 1.
In the present machine, a plurality of weaving units are provided which are carried by the secondary frame, in the present instance, fifty of such units being provided. The weaving threads from the thread spools are fed upwardly to the weaving units (Fig. 1), and as the braids are woven, the completed strip is gradually being drawn up onto the friction roller 45 which is intermittently rotated to draw up the material and take up any slack in the material as it is being fed upwardly. From the roller 45, each completed strip of braid is fed to a spool 1-6, there being a plurality of said spools mounted on .suitable supports 17 formed at the top of the machine on a suitable longitudinal bar 18 extending from the top of the frame member 3 to the top of the frame member 4t. The supports 17 extend to both sides of the machine as illustrated in 17, in order to support the row of spools on each side of the machine. These spools are intermittently rotated, each spool being provided with a pulley 49, see Fig. 1, which is connected by a beltwith a friction rolle' 51, two such friction rollers being provided, one for each row of spools 41-6. These friction rollers 51, 51, are provided with ratchet wheels 52, 52, which are adapted to be engaged by pawls 53, 53, carried on the cross piece 5 1, which is fixed to the cross arm secured to the rods 32, and consequently with each ascent of the secondary frame 7 the friction rollers 51, 51, will be rotated a notch in order to in'ipa-rt a partial turn to the spools 4.6, to wind up the braid thereon.
With each ascent of the secondary frame, the weaving threads, to wit, the woof or tying threads, just positioned, are given an upward thrust in order to crowd up the woof threads into final position. This upward thrust is caused to be imparted to the woof or tying threads by packing means, consisting in the present instance of a series or set of teeth or points 56 which are secured to cross pieces 56 and mounted on a longitudinal slide frame 57 which is mounted to slide longitudinally between the supporting bars 58, 59, 60, and 61, and the cross pieces 9 of the secondary frame 7, the supporting bars 58, 59, 60 and 61 being secured to the cross pieces 9, as indicated in Fig. 3. The points 56 are only caused to cross the woof or tying threads in the upward ascent of the secondary frame 7, in orderto permit the woof or tying threads to be positioned in the course of weaving. The points 56 not only function to impart an upward thrustto the woof or tying threads, as they are positioned in the course of weaving, but also cooperate with the weaving units in the n'ianner hereinafter to be described.
In order to impart a sliding movement to the frame 57 and consequently to the points 56, the frame 57 is connected by means of the pin 117 and slot 118 connecting the tongue 117 with the lever 119 fulcrumcd at 120 by a pin journal-ed in the bearing 62 secured to the longitudinally extending bar 63 secured to and extending from the frame member 3 to the frame member 1, see Figs. 1 and 4-. The lower end of the lever 119 is connected by the spring 641 to an abutment 65 formed in the frame member 4;. The spring 6tafunctions resiliently to hold the roller 66 pivotally con nected to the lower end of the lever 119 against the cam face 67 of the cam 68 formed on the shaft- 69 of the disk 35. In other words, with every turn of the disk 35, and consequent upward rise of the secondary frame 7, the lever 119 will be given an impulse to move the slidable frame 57 longitudinally in the secondary frame 7.
As an additional guide for the threads extending up through the secondary frame 7, the sliding frame 57 is provided with the grill frame 70 having a plurality of longitudinally extending wires 71 which are carried around cross rods 72 in order to form spacing means between the longitudinally extending wires 71 and at the same time afford yielding means between said longitudinally extending wires. The frame 70, as shown in Fig. 3, is secured within the sliding frame 57 and fixed in place by the supporting bars 59 and 60, the grill frame 70 being spaced from the supporting bars 58 and 61 of the sliding frame 57.
The weaving mechanisiiu, now to be de scribed, forms the main feature of the pre. nt invention and functions wit-h the points 56 to perform the weaving operation, without a shuttle, in other words provides av shuttlel-ess loom. On the downwardly extending flanges of the longitudinal bars 8, see Figs. 3 and 17, there are secured the bearings 73 for the shafts 7 1 and 75 which have secured thereto on the ends thereof, protruding beyond the frame 4, the pinions 76 and 77 respectively. The pinions 76 and 77 are supported by the brackets 76" and 77 respectively connected to the bracket 12. The shafts 7 1 and 75 are also provided with the gears 78 and 79, as shown in Figs. 3 and 17, to cooperate with the racks of the slides 80 and 81 respectively. All of the slides 80 are connected to one another by the longitudinal bar 82 and all of the slides 81 are connected to one another by the longitudinal bar 88, and consequently all of the slides 80 will be moved simultaneously with the rotation of the pinions 76, and all of the slides 81 will be moved simultaneously with the rotation of the pinion 77. On the bars 82 and 83 there are suitably mounted the woof thread controlling means, such as the weaving needles 8 1 and 85 respectively. The needles 8 1 and 85 function in pairs, each pair having a needle 8 1 and 85 which operate alongside of one another, as illustrated in Fig. 3. The needles 8 1- and 85 move in opposite directions, in other words, they approach simultaneously, and recede simultaneously. This actuation of the needles 8 1 and 85 is caused by means of the segment 86, the teeth 87 of which engage the pinion 77 and the idler 88 which meshes with the pinion 76 offsetwith respect to pinion 77. The idler 88 as illustrated in Fig. 2, is suitably mounted on the support 89 secured to the bracket 12. The segment 86 is pivoted to the cross piece 55 and consequently moves vertically with the secondary frame 7. For causing the segment 86 to rock to and fro, there is provided the lever 90 which is pivoted at the top of the machine to the upper end of the frame 1 on the stud shaft 91 and extends down to cooperate between the rollers 92 and 93. The lever 90 has pivoted thereto the link 9st which is piv oted to the eccentric 95 which eccentric in turn is operatively connected to the shaft 99 (Fig. 2) which has a bevel gear 100 at its lower end in mesh with the bevel gear 101 on the main drive shaft 24.
The segment 86 is caused to make a complete to and fro movement for each ascent and descent of the machine. As will be clear from Fig. 3, for each rearward movement of the segment 86, the pinions 88, 76 and 77 are caused to rotate the shafts 74 and 75 in turn to cause the slides 80 and 81 to recede from one another, and each forward reciprocation of the segment 86 will cause the bars 82 and 83 with the slides 80 and 81, and the thereby supported needles 84: and 85 to approach one another.
The needles 84 and 85 as clearly shown in Figs. 7, 9, and 10, are each provided with an eye 102 at its end, to receive a woof or tying thread 103 or 103". These woof or tying threads, as shown in Fig. 9, are caused to cross over the warp threads 10 1 in the course of weaving.
In order to cause certain of the warp m- Id threads alternately to cross, first to extend on one side of the woof or tying threads and then on the other side of the woof or tying threads, according to the design intended to be produced, there is provided below the guide frame 7 0 two harness forming members consisting of a series of lorgitudinally extending metal jacquard strips 105, shown in Fig. 7. These strips are provided with a plurality of openings 106, a jacquard strip and openin for each warp thread, 10 1, the warp thread 10%, passing thorugh the opening 106 and being controlled by the jacquard strip 105 which in turn is controlled by the design controlling mechanism located in the auxiliary frame 1. The design controlling mechanism is of the usual jacquard type, used with lace-weaving machines, and will not be described in detail. it is believed sufficient here to state that depending upon the design to be produced in the braid, the required jacquard cards are mounted on faces of the perforated jacquard base 107, and this jacquard base with the cards mounted thereon will function with the usual pins (not shown) in turn to actuate the jaccpiard-strip manipulating bars 108 each of which is connected with a jacquard strip 105.
The (re-functioning of the jacquard strips 105 with the needles 84- and 85, the prongs or points 50, and the vertical reciprocation of the frame 7 will now be described in detail.
The warp threads for a braid or web are spread out and pass through the slay 163 where the warp threads are separated into odd numbered and even numbered warp threads. There is a slay 163 provided for each web, this series of slays being secured to the cross-bar 63, illustrated in Fig. 1, as extending longitudinally of the main frame 2 and secured to the end frame members 3 and at. The designation of one set of the warp threads as even numbered threads and the other set as odd numbered threads is purely arbitrary and merely so designated to facilitate the description of the procedure of these threads. The odd numbered warp threads 10st will be passed through the openings 100 of the odd numbered jacquard strips 105 and the even numbered warp threads 10 1 will be passed through the openings 106 of the even numbered jacquard strips 105, and from these jacquard strips 105, the threads 10-1- will pass through the grill 70, and, in the course of weaving, after having become a part of the web or braid 165 then.
extend up to and over the friction roller 15, to the receiving spool 16.
The woof threads 103 and 103 of which there are two to each web or braid being woven, also pass up through openings formed in the slay 163, the openings for the woof threads preferably being spaced from the openings for the warp threads. The woof threads 1 3 and 103 then pass from the slay 163 upwardly to the jacquard strips 105, and for convenience in the present instance, pass between adjacent jacquard strips up to and through the eyes 102 of the needles 84 and respectively and from there into the web or braid 165 being woven.
As illustrated in Fig. 7, the warp thread controlling means, such as the jacquart strips 105, are provided with a series of thread openings 106. As is customary with jacquard mechanisms, one set of jacquard strips are generally operated in opposition to another set of jacquard strips. As an in stance, in plain weaving operations, odd numbered strips are actuated in the same direction and the even numbered strips simultaneously in the opposite direction, this aetuation being alternated so that the odd numbered and even numbered strips will simultaneously be actuated to and fro but in opposite directions. By this means, as is common in the weaving art, the threads controlled by the odd numbered strips will be deflected to one side to form a row of threads extending in a plane and the odd numbered threads be at the same time deflected in the opposite direction to form a row of threads in a plane, which rows of threads will form an opening between them through which opening in the looms provided with shutties, the shuttles are caused to be reciprocated. In the present instance, as shown in Figs. 7, 8, 9, 10 and 11, a set of needles 8e: and is caused to be reciprocated tl'irough each opening formed by a pair of rows of threads as aforesaid. As shown in Fig. 7, when the row 138 of warp threads 10%, arbitrarily designated as the odd numbered threads, are deflected forwardly, and the row 139 of warp threads 1.0 1, arbitrarily designated as the even HUIIIlQQI'GCl threads, are deflected rearwardly, and the secondary frame 7 is at its lowest position, the needles 8 1 and 85 of a set are disposed in their retracted or receded position.
Then before the slide frame 57 is actuated to bring its prongs or points 56 into engagement with the row of threads 139, the nee dies 8- and 85 of a set will have been caused to cross over as shown in Fig. 9, and there with cross the woof or tying threads 103, 103 whereupon the slide frame- 57 timed therefor will cause the prongs or points 56 toextend between the threads 10% of the rearwardly deflected row 139 and cross the opening, into engagement with and between the threads 10st of the forwardly extending row 138, the points 56 when so positioned extending above the needles 8st and 85 and below the crossing point of the woof or tying threads 103 and 103". The several elements of the machine are timed so that the secondary frame 7 will be caused to move upwardly and therewith press the points 56 upwardly, carrying therewith the woof threads just crossed, simultaneously causing the needles 8% ant to recede, and thereupon, and before the auxiliary frame is caused to descend, causing the jacquard. strips 105 to reverse their movement so that the row 138 of threads 104 will t ion be deflected rearwardly and the ro 135) of threads 104 deflected forwardly as shown in Fig. 10, by which action the warp tl'ireads will socure a loop of each of the woof threads 103 and 103*, each woof thread having had a portion of itself laid. over upon itself, as illustrated in F 0, and thereupon causing the prongs 56 to be withdrawn.
The prongs 56 thus form arresting means to hold the woof threads or loops formed by the woof threads in position until the warp threads have been caused to cross and tie in the loops.
With the ensuing descent of the auxiliary frame 7, the needles 8% and 85 or a set having been withdrawn, and the arrested woof threads 103 and 103 having been crossed by the rows 138 and 139 of warp threads, as shown in Figs. 10 and 11, will hen upon the succeeding inward movement, cause the woof threads 103 and 103" to secure the warp threads 10 1 in place.
Of course the woven n'ia'terial may be woven into various designs ocpending upon the jacquard cards used on the jacquard base 107.
The present invention lends itself also to the formation of various lJO\TlQI' styles or edge fringes, see for inst nee he loop edge fringes illustrated in ll'ig. 14 as compared to the straight edged formation illust ated in Fig. 13. The edge formations depend upon the tying of several elemen s of the mechanism. As an instance, mien the spread of the prongs or points 530 correponds substantially with width of the material being woven, slack in, the woof threads being taken up, and the throw of the needles 8-l and 85 accord i-iubstantially to tile v-:..lth of the material being woven, a sul :tantially straight edged imiterial may with facility be produced. On the other hand, if either the throw of the needles 841 and 85 is much greater than the width of the material being woven, and the timing of the several elements is regulated accordingly, loops 140, such as illustrated in 1 1, may with. facility be produced along the edges of the material being woven. Cm the other hand, if the spread of the teeth or points extends beyond the width of the material, and the woof threats are caused to extend around such outwardly extending s1 read of points 56, a similar form of loop such as the loops 1&0 may be provided. Furthermore, if the spread of te th or points 50 is less than the width of the material being woven, the ends of the loops of the woof threads may not extend to the very edges of the material being woven, and still another form of edge would thereby be produced. it has also been found that, when the slack in the woof threads is not entirely taken up, depending upon the tension on said woof threads, overhanging loops of one length or other may be formed by the woof threads along the edges of the material be ing woven. It has furthermore also been found that the throw of the needles as compared to the width of the material can likewise produce various edge formations.
These various edge formations depend directly upon the provision of a shuttlcless loom, such for instance as the loom herein provided, and the method of forming the same with its various edge formations, constitute important parts of the present in vention.
By means of the co-functioning aforesaid 0f the jacquard strips 105 with the needles 8% and 85, the prongs 56 and the vertical reciprocation of the frame 7, when forming a plain web such as illustrated in Fig. 12, it will be seen that each woof thread 103 and 10h will form a loop at one edge of the web that is not secured. For instance,
, following the woo-f threads in that web which we will designate as 103 and 103", it will be found that on the lefthand edge of the web there illustrated, the woof thread 103 will form the loops 103 not tied by warp threads 104, and that onthat same lefthand edge of the web the woof thread 103 will form the loops 103 tied by the warp threads 10%, and that on the righthand edge of the web, the woof thread 103 will form the loops 103 not tied by the warp threads 10 1 and that the woof thread 103* on that edge will form the loops 103 tied by the warp threads 10st.
Fig. 1i by following the woof threads 103 and 103, it will be found that the overhanging loops 140 are the untied loops, of the respective woof threads 109% and 101%".
l v hile for ordinary purposes, the braids illustrated in Figs. 12 and 1 1 will maintain their structure without danger of unravelling, any suitable stitch such as the lock stitch l ll may be provided along the edges of the web, as illustrated in vFig. 15, in which case the untied loops will be positively secured in place and the web protector! against all danger of unravelling.
It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention set forth in the appended claims.
