1o claims. 1
This invention relates to looms, and more particularly to those of the jacquard type especially adapted for use in weaving narrow fabrics such as woven labels, trimmings and the like.
The primary object of the invention is to provide a loom of this character of simplied and lightweight construction; which will operate at high speed and with eilciency; which can be manufactured at much lower cost than the conventional looms in this category and which will nevertheless have greatly increased work output.
In addition to the advantages above enumerated, the invention contemplates the employment of a horizontally movable hatten carrying a plurality of vertically movable shuttles, the latter being mounted for gravitationaldescent to carry the weft threads across the warp.
Another object of the invention is to provide in a loom of this character, means by which the fabric is woven with the plane of the produced' fabric disposed vertically whereby gravity may be utilized to carry the shuttles downwardly to thereby insert the -weftthreads in the fabric.
Still another object'of'the invention is to provide a loom in which the operating parts are so arranged that a plurality of fabrics of similar design can be simultaneously woven while, at the same time, the loom will occupy a minimum of iloor space.
These and other objects are attained by the structure hereinafter described and more particand associated parts;
is woven with the plane of the fabric disposed vertically. Therefore, the accompanying drawings show the co-operating parts of the loom which carry out theimeans of operation of the above features.
The loom hatten includes the beam I, which is supported at its ends by the arms 2. Each arm 2 is pivotally attached at l to a lug 5 extending from the beam I. The arm -2 is part of a. bell crank lever arrangement which has a second arm 6 mounted to rock on shaft 1. A rod 8 extends to suitable cam or similar mechanism, the operation of which aids in causing descent of the shuttle push-rods to be described.
The batten frame is shown at I0, the same consisting of an elongated, substantially rectangu- 'lar frame, clearly shown in Fig. 1, upongwhich a number of groups of shuttles 2B are carried. The loom shown is of the gang type, so that iive fabrics can be simultaneously woven, each fabric, in the arrangement disclosed having weft threads of three colors inserted, there being three shuttles shown for each fabric. The batten frame Il) is mounted to have a longitudinal reciprocating movement along the top of the. beam I, by means of a suitable operating mechanism including the bell crank II having an arm I3 pivotally attached at I4 to one end of a link I5, winch has its opposite end pivotally attached at I 6 to the hatten frame. The-second arm of the bell crank is pivotally attached at I'l to a push-rod I 8 extending from suitable cam or other mechanism 'acting to move the hatten frame back and forth Fig. 3 is a top plan view of the structure shown tle guides and the latch means thereon for holding the shuttles in their raised position.
The present invention relates particularly to the loom batten, the manner in which it is moved;
to the shuttles and the means of operation of the same, and the novel manner by which the fabric along the top of the-beam I for a limited distance and in proper'timing. To permit longitudinal movement of the hatten IIl by means of mechanism above` described, rollers I9 are carried by the batten, the same riding upon the suitable track surfaces 20 provided on the top of the beam I. Provided on the forward face of the upper bar 2| of the batten frame I0 are the upper shuttle guides 22 shown clearly in Figs. 6 and 8. Each guide is provided with the three channels 23,- 2| and 25 in each of which a shuttle 25 is slidable. The rear portion 21 of each shuttle 26 .is in the form of a spur provided with an inclined cam surface 28 which, upon rising movement of the shuttle, acts to force a spring latch 29, having a part normally located in the channel of the shuttle guide, out of the way, to permit passage of the shuttle to enable it to reach its elevated position, as shown in Fig. 6. When the shuttle reaches said elevated position, the padded shoulder 30 on the lower end of the spur 21 of the shuttle, takes over a shoulder 3| on the latch 29 so that the latch then holds the shuttle in its raised position. Each of the shuttle guides 23, 24 and 25 is provided with one of the latches 29 so that when each shuttle israised up in its upper guide it will be engaged by one of these springpressed latches 29 and be thus held in its raised position, and so maintained until released by means to be described. The latches 29 for each group of shuttle guides 22 are mounted on a shaft 32 at the back of the shuttle guides, said shaft being secured in the lugs 33 and 34. (See Fig. 8.) A torsional spring 35 tends to hold each latch forwardly and in position to have its shoulder 3l engage under the padded shoulder 30 of its shuttle 26 when the shuttle is raised to its elevated position. y
The bottom shuttle guides are shown at 36, the same being arranged in groups of three and being secured on the lower bar 31 of the batteri frame I directly below the upper shuttle guides 22.
The bottom of the lower shuttle guides 36 is closed by a stop plate 38 lined with a pad 39 of soft material, such as felt. When the latches 29, or either of them, are released, they will free the shuttles 26 held by them, and the shuttles so released will descend by gravity and slide down in the lower shuttle guides 36, thus carrying their threads across the warp threads 40 extending through the reed 9 and positioned between the upper and lower shuttle guides.
The shuttles 26 are adapted to be selectively raised by a lifter rod 4I, there being one of these rods for each group of three shuttles as clearly seen in Fig. l. By longitudinal movement of the hatten frame I0 in proper sequence according to the controlling mechanism, each shuttle is positioned at the right time directly above the lifter rod 4I which is then raised and engages the padded shoulder 30 of the shuttle 26 below which it is then located, to raise the shuttle and lift it upwardly into the upper shuttle guide and past the latch 29 which then engages the raised shuttle under its shoulder 30 to hold it in such 'elevated position until it is caused to descend by gravity upon retraction of the latch 29 at the proper moment. The lifter rod 4I is moved upwardly, as above described, through a passage 42 extending through the beam I, the upper end of the rod passing through the aligned apertures 43 in the plate 38 and padding 39 at the bottom of the lower shuttle guide, to thus reach and engage against the padded shoulder 30 on the shuttle and raise the shuttle. The lower end of each of the lifter rods is provided with a disk-like head 44 maintained under a bracket 45 secured on top of the lifter bar 46. Said bar 46 is raised and lowered by means of the bell-crank levers 41 and 48 (Fig. l). Lever 41 is -pivoted at 49 at the end-of a downwardly extending bar 50, said bar being secured to and extending downwardly from the beam I. The arm I of the lever 41 is pivotally connected to the bar 46, as indicated at 52. A third arm 53 on lever 41 has its end pivotally attached at 54a to the rod 54 which is raised and lowered by suitable cam or other means.
The lever 41 is connected to the lever 48 by means of a connecting rod 55, and the rod 49 has its lower arm 56 pivotally attached at 51 to the lifter bar 46. Lever 48 is pivoted at 58 in the end of a bar 59 secured to and extending downwardly from the beam I as clearly seen in Fig. 1. This arrangement is such that a downward pull 4 exerted on the rod 54 will swing the levers 41 and 43 in such a manner as to cause the bar 46 to be lifted upwardly, this raising the several lifter rods 4I and causing them to raise the shuttles then located above them'and to bringthe shuttles to their elevated position where they will be held by the latches 29 until they are required to descend and carry their weft threads` across the warp.
Behind the batteri frame III is a frame-work .that is fixed to and is carried by the beam I and on which the batten frame IIJ is slidably mounted. Said frame-work includes a plurality of uprights or vertical bars 60, (Fig. '1) and between pairs of these uprights the reeds 9 are supported. The uprights 60 are attached at the back of the beam I by the screws 6I and directly above the beam I each pair of the uprights is connected by a rail 62 on which a grooved bar 63, secured to the back of the batten frame III by the screws 64, is slidable. The uprights 60 are also connected at their tops by the upper rail 65 secured to said uprights by the screws 66, and a grooved guide bar 61 secured at the back of the top bar 2I of the batten frame I0 by the screws 68 is slidable on the rail 65. Through the arrangement described,
' it will be noted that the batten frame I0 is longitudinally slidable along the beam I, being supported thereon on the rollers I 9 and being guided on the frame-work secured to the beam, by the engagement of the grooved bars 51 with rails 65 and the engagement of the lower grooved bars 63 with the lower rail 62. 'I'he frame-work, including the uprights 60, includes longitudinally extending cross bars 69 which serve to strengthen the frame-work structure. At the top, the several uprights are provided with bearings 16 in which a rocking shaft 1I is mounted. For each group of three shuttles, the shaft 1I carries a linger 12 arranged to be positioned in front of an upstanding part 13a on any one of the latches 29 in each group of shuttles. That is to say, the arrangement is such that when a shuttle is raised and is held in elevated position by one of the latches, the movement of the hatten is so timed thatl when required it will position that shuttle in front of the ilnger 12 and whenthe pattern requires the insertion of a. weft thread of the color carried by that particular shuttle the rocking shaft 1I will be turned and iinger 12 will then draw back the latch 29 and allow the shuttle to drop by gravity and carry the weft thread across the warp.
For causing the required' rocking movement of the shaft 1I, a tripping member or nger 13 is provided, said finger being attached at one end of the rocking shaft 1I and being provided with a spring 14 (Fig. 2), which normally holds the shaft 1I with its linger 12 extended forwardly and away from the latch behind it. Disposed behind the upstanding finger or tripping member 13 is a bar 15 (Fig. 2), provided at its lower end with a laterally projecting pin 16. At the proper time in the operation of the loom when the descent of a raised shuttle is required, the batten is swung backward,
ortoward the right as viewed in Fig. 2, and this movement ofthe batteri brings the tripping member or inger 13 in contact with the pin 16. This will cause shaft 1I to be rocked in its bearings 16 and the iinger 12 will be swung to retract the latch 29 with which it is in registration. and the shuttle which is then being heldin elevated position by the latch so released will descend by gravity and carry the weft thread across the warp. The -bar 15 is mounted for vertical sliding movement in guides 11 and 18 secured on a portion 18 I of the frame of the loom and this sliding bar 15 is adapted to be raised and lowered at the proper time by means of an arm 80 pivoted at 8l to the frame member 18. I'he arm 80 is adapted to be rearwardly, or toward the right as viewed in Fig. 2
and during thatmovement in the weaving of the fabric, a shuttle is not to be dropped, the bar 15 is then held in elevated position by the arm 80 so that the tripping member or nger 18 will then clear the pin 18 and thus the shuttle will not be released. f j
The heddles for the loom are shown at 85 in Fig. 3, the details of one of the heddles being made clear in Figs. 4 and 5. It will be therein-'seen that each heddle consists of a at tape 88, secured'at its lends to the wires 81 and 88. Each heddle is provided with a guide loop 89 through which the warp threads 40 pass. It will be observed that the bank ofheddles is so arranged that the warp threads are disposedabove one another with the result that the plane of the woven fabric, aportion of which is shown at 80 in Fig. 2 is disposed vertically as distinguished from the usual horizontal disposition of the faces or planes of the fabric in conventional weaving practice.v 'I'he wires 81 and88 at the opposite ends of the heddles are carried below rollers Si at theopposite `ends ci the loom,rwhich Wires thence extend upward into the usual Jacquard loom mechanism. As is well understood, through such mechanism. the heddlesfare moved to cause the warp threads engaged by them to be drawn aside as required by the pattern to permit of the selective insertion of the weft threads by the required shuttles.
From the foregoing, the operation of the improved loom mechanism will be readily understood. In the form of apparatus disclosed, ve fabrics of the same pattern can be woven, but it will be understood that by the employment of a longer batten and an increased number of shuttle gangs, the number of pieces beingA simultaneously woven canbe increased. As the heddles shift the warp threads according to the jacquard pattern to be produced, the change-motion mechanism of the loom will selectively raise the shuttles in their guides and permit the required descent of the raised shuttles by gravity, and on the forward swing of the batten, the reed 9 will pack the inserted weft threads in the shed 9| of the fabric. It will, of course, be understood that the several mechanisms are timed for proper sequence so that the resultant fabric will be 4woven according to the pattern of the jacquard card arrangement.
To facilitate the roll-up of the woven fabric as it leaves the loom, the fabric is shifted from a vertical position to a horizontal one. This is done by means of a wire guide loop 95 through which the woven fabric is passed and is guided flatwisely over a bar 86 and then drawn downwardly to be wound up in a roll by a suitable take-up means of conventional form. f
While I have herein shown a single embodiment of the invention, it is obvious that various modifications may be made in the same without departing from the spirit of the invention. The number of pieces woven simultaneously may be increased or decreased; the numberof shuttles in each gang might also be changed and the elements of the 6 described mechanism might be changed in shape `and design. all of which can be done without departingfrom the scope of the invention as.. ex-
pressed in the claims appended hereto.

In a loom, a batten including a beam extending transversely of the loom, means for swinging said beam to and from the front of the loom, a batten frame mounted on top-of the beam and capable of sliding reciprocating movement thereon, a fixed structure on the beam for guide and capable of vertical sliding movement therein, latches at lthe upper end of the guide for engaging the shuttles and holding the same in raised position, latch-release means carried by the ilxed structure. means for engaging said latch-release means ,on the rearward swing of the beam to render said latch-release means ei'- fective to release the latches and allow gravitational descent of the shuttles. and means carried by the beam for selectively raising the shuttles` in the guide. l
7.*'In a loom, a beam mounted for swingingI movement, a batten frame mounted for limited longitudinal sliding movement on the beam, a. plurality of shuttles mountedon the batten for vertical ascent and descent thereon and arranged thereon in groups. guide means for the shuttles,
. 8 9. In a loomof the character described, a plurality of horizontally disposed heddles for supporting a plurality of vwarp threads in superimposed relation, a hatten carrying a plurality of vertically slidable shuttles, guides for said shuttles, means for elevating selected shuttles in their guides, means for holding the shuttles when the same lare raised, releasing means for allow- Zing said shuttles to descend by gravity and carry weft threads acrossthe warp threads, a reed carriedby the hatten for packing the weft threads in the shed while the plane of the woven fabric is vertically disposed, and guide means for guiding i the woven fabric to a positionwherein its plane means .for selectively raising one or the other of v the shuttles in each group in said'guide means. means for retaining the shuttles inraised position in the guide means, and means for selectively freeing the shuttles-retaining means to there-V by allow the shuttles to drop by gravity.
8. In a loom for weaving narrow fabrics, a plurality of horizontally disposed heddles for engaging a plurality of warp threads arranged in superimposed relation, a batten carrying a plurality of shuttles arranged for vertical movement to carry weft threads across the warp threads to thereby produce a woven fabric having its plane surface disposed vertically while being woven, means for movingthe shuttles vertically consisting in a pluis horizontally disposed to facilitate wind-up of 3 the woven'fabric.
10. In a loom of the character described, a betten carrying' a plurality of shuttles arranged for vertical ascent and descent. a. lifter located below the. shuttles, means for raising and lowering the lifter, means for shifting the batten in a direction ltransverse to,y the direction of ascent and descent of the shuttles whereby any selected shuttles can be positioned above the lifter to l thereby cause the lifter to raise said selected shuttle, means for holding the raised shuttle in its elevated position and means for freeing said shuttle-holding means to thereby allow the raised shuttle to descend by gravity.
