BOBBIN TAKE-UP FOR LOOMS.
SPECIFICATION formingpart of Letters Patent No. 747,307, dated December 15, 1903.
Application filed October 6,1902.
To all whom/it may concern.-
Be it known that we, NATHANIEL H. MER- RIAM and EDMUND H. SAWYEB, both residing at Lexington, in the county of Middlesex, Commonwealth of Massachusetts, have invented an Improvement in Bobbin Take-Ups for Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing likeparts.
Our invention relates to narrowware looms, particularly to looms for weaving simultaneously a plurality of strips, ribbons, or tapes for any of the various uses for which such strips or fabrics are adapted. In looms of this type, as heretofore constructed difficulty has invariably been encountered in providing a proper take-up for the several woven strips of fabric, it'having been found that ordinary take-up mechanisms, such as used in the weaving of wide fabrics, are wholly unadapted for narrow-ware looms. Prior to our invention the common practice has been to lead such strips .or tapes from the feed or take-up roller into boxes, where they quickly accumulate, requiring the loom to be stopped and the strips removed before the loom can continueto operate.
Attempts have been made to wind the woven strips upon bobbins or spools frictionally mounted upon a rotating shaft; but this means has proven unsuccessful, because of inability properly to control the rotative speed of the bobbins. Furthermore, where the strips are wound with the successive convolutions overlying one upon another, or where there is a very short lateral traverse, the bobbins are found to build up so rapidly as to require frequent stopping of the loom for the insertion of new bobbins.
Our invention aims to eliminate these diffi-. culties by providing bobbin take-up means having the capacity to receive any desired length of the woven fabric, thus permitting the loom to be run uninterruptedly, excepting,of course, stopping for breakage of filling, whereby the greatest possible output of the loom is obtained. Our invention also leaves the woven strips in suchform as to permit of Serial No. 126,049 (No model.)
their being cut whenever desired and stored or handled without danger of collapsing the bobbin.
. The various features of our invention will be best understood from a description of one embodiment thereof shown in the accompanying drawings, wherein- Figure l, in front elevation, shows an end portion of a narrow-ware or ribbon loom of ordinary construction equipped with devices for carrying out our invention; Fig. 2, a rear elevation of the parts shown in Fig. 1; Fig. 3, a cross-section taken on the dotted line 3 3, Fig. 1; Fig. 4:, a detail showing the gearing for rotating the bobbin-driving cylinder and traverse-cam; Figs. 5, 6, and 7, details, respectively, of one of the traverse-fingers.
Referring first to Figs. 1 to 3, inclusive, the frame A, breast-beam a, lay B, with its reeds b and usual narrow-ware shuttles b,
said lay being driven from the crank-shaft b the harness-frames O, suitably connected with the harness-lever c,with driving mechanism therefor, are and may be of usual type or construction so far as our invention is concerned. Below the breast-beam a is the usual feed-roller d, the same being journaled at its ends in the frame and positively driven by any of the usual feed-roller-driving mechanisms typified at D, Fig 1. This feed-roller, as here shown, is provided with a friction-surface clsuch, for instance, as sandpaper-and upon this friction-surface rest a plurality of felt-covered rollers (1 equal in number to the number of strips of fabric capable of being simultaneously woven upon the loom, said rollers d being mounted in the free ends of the swinging carriers (1 depending from the breast-beam.
In the present embodiment of our invention the bobbins are driven by a cylinder which is independent of the cylinder or roller d, said bobbin-driving cylinder being here indicated at E. This cylinder may be located at the rear or at the front of the 100m, as convenience dictates, the same being herein shown at the rear of the loom. This bobbindriving cylinder may be driven in suitable manner, as by the sprocket-chain e, from the feed roller or cylinder (1 or shaft thereof, the said cylinders or rollers E and d thus having the same rotative speed.
The bobbin driving cylinder preferably has a friction-surface, such as sandpaper, and upon this surface rest the peripheries of the bobbins F which are being wound or formed. These bobbins are wound upon any suitable coresf, journaled in the free arms of the carriers f, fulcrumed at f Above the bobbins is arranged a traverseshaft h, mounted to slide endwise in suitable hearings in the frame and provided along its length with a plurality of traverse-fingers h, one for each bobbin to be wound. v
Referring to Figs. 2 and 4, the traverseshaft at one end of the loom is provided with a roller-stud 72?, which engages the traversecam 7Z3. (Shown as loosely mounted upon a stud 71 The hub of this cam (see Fig. 4) is provided with a gear h driven through an intermediate gear h from and by a pinion h fast on the shaft of the bobbin-driving cylinder E, so that the rotative speed of the traverse-cam and the traverse movements of the traverse-fingers bear always a fixed relation to the rotation of the bobbin-driving cylinder E.
Referring now to Fig. 3, the warps w from a suitable source (not shown) are conducted in usual manner to and through the harnessframes and the reed on the lay, and in the movements of the latter and the shuttles carried thereby the weft-threads are interwoven therewith at the fell w, the completed or woven strips or ribbons being carried, for instance, about the guide-rods Q02, thence downward .to and about the feed-roller d and about the smaller tension-rollers d resting in contact therewith. The woven ribbons or tapes are then conducted, preferably, about a guide-rod w from which they pass to the traverse-fingers 71.. One series of ribbons or tapes, comprising ordinarily one-half those in the loom, are shown conducted directly to the rearwardlyprojected traversefingers, passing through slots h therein to the top sides of the fingers, thence back again through other slots to the cores of the bobbins or to the bobbins upon the cores. The other series of tapes for the forwardly-projecting fingers, Fig. 3, are carried over the traverse-rod h and preferably rest in guidenotches 71 in the upper ends of their respective traverse-fingers, passing thence behind and under the traverse-rod, thence through their respective fingers to the top sides thereof and back again to the under sides of the fingers and to the bobbin-cores or to the bobbins thereon. In this manner the several traverse-fingers are held by the tension upon their respective tapes or ribbons in operative contact with the bobbins which are being built up.
In'the operation of the loom the rotative speed of the feed-roller is adjusted in usual manner by means ofits feed or driving mechanism to take up or feed the fabric ataspeed that will give the desired number of picks to the inch.
Since the bobbin-driving cylinder E has the same surface speed as the feed-roller d, the surface speed of the bobbins, which rest by gravity in contact with the said cylinder E, likewise is the same as that of the said feeding-roller, and this regardless of the diameters of several bobbins. In fact, some of the bobbins may be ofone and others of a different diameter, yet the winding operation remains the same, since the surface speed at which the winding takes place remains uniform at all times, and since the traverserod h is driven positively by and from the bobbin-driving cylinder E it follows that the movements of the several traverse-fingers bear a constant ratio or proportion to the rotative movements of the several bobbins, whatever be the respective diameters of the latter. Consequently uniformity of winding is insured throughout the entire building up of the bobbin.
The traverse-fingers h, Figs. 5 to 7, are provided, respectively, with lugs h", which embrace and are adjustable upon the traverse-rod h, and between each pair of lugs 71. of each traverse-finger is arranged a collar h also adjustable on the traverse-rod and having a set-screw h'or other clamping means whereby the position of each collar and of each traverse-finger along the rod it may be determined and adjusted at will. The surface or winding speed of the several bobbins being identical with that of the feeding-roller (1, there is no variation in tension upon the fabric strips or ribbons, consequently no tendency to pull over or collapse the bobbin as the latter increases in diameter.
Our invention also provides for winding in.
a single bobbin sufficient length of fabric to care for an entire weeks output of the loom, or more if desired. While this would not be practicable were it attempted to wind the successive convolutions of the fabric one directly upon the other, our invention contemplatesthe laying of one convolution in advance of or behind the preceding, forming relatively long bobbins, the length of traverse from one to the opposite ends whereof greatly exceeds the distance separating adjacent tapes being woven upon the looms. Thus the diameters of the bobbins may be much reduced, making it possible to wind long lengths of fabric upon a single bobbin without requiring the cutting thereof.
Since the loom is fitted to weave as many strips of fabric as are possible in a given length of loom, the increase of the lengths of the bobbins beyond the spacing of the fabric strips when Woven requires the bobbins to be arranged to rotate about different axes instead of one and the same axis or carryingshaft, as heretofore.
In the present instance we have provided for this by arrangingthe bobbins alternately at opposite sides of the vertical center of the driving-cylinder E, said bobbins being thus staggered one relative to another and overlapping each other, as it were, so that each bobbin may thus be built up of a length at least twice what would be possible were the bobbins arranged substantially in line, as heretofore.
The lengths of the bobbins are such that there is no liability whatever of their collapse after having been once formed. Thus they may be stored and handled with great facility.
Our invention is not limited to the particular embodiment here shown and described, for obviously the same may be varied without departing from the spirit and scope of the invention.
