YARN=SEPARATOR FOR SPINNINGHFRAIVIES.

SPECIFICATION forming part of Letters Patent No. 476,731, dated June '7, 1892. Application tiled August 25, 1890. Serial No. 363,055. (No model.)

To @E wiz/0m it may concern:

Be it known that l, ALFRED D. CHANDLER, a citizen of the United States, residing at Chelmsford, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Yarn-Separators for Spinning-Frames, of which the following is a specification.

My invention relates to yarn-separators for spinning-frames or devices adapted to be arranged between adjacent spindles of a spinnin g-machine to preventinterference between the yarns being spun and wound upon such spindles; and the object of said invention is to prevent the yarns being caught on the ends of the separator-blades; to permit the use of a very light traveler and a very high speed of the spindle; to permit the use of a very wide separatorblade, thus insuring a more perfect separation of the yarns; to enable the separator-blades to be quickly placed in a position where they will not interfere with the operation ot' dofing and to retain them in such position by their own weight and to enable said separator-blades quickly to return to their normal position; to enable all the separatorblades to be removed from the spinning-frame, when desired, quickly and without the removal of or loosening of screws or other fastenings, and to secure means of ready adjustment of the length of the traverse of the sep arator-blades and their shortest distance from the ring-rail.

In the accompanying` drawings, Figure l is a front elevation of a part of a ring-spinning frame, showing the roller-beam, thread-board, fingerboard, guide-rail, spin d le-rail, ri n g-rail, lifting-rod, cross-shaft and its arm, spindles, bobbins, cops, and separators, and a part of the devices which connect the separators to each other and a part of the devices which operate said separators; Fig. 2, a vertical section on the line 2 2 in Fig. l, showing a leftside elevation of my improvement and its supporting and operating parts, the position of the separator-blade in the operation of dolfingbeingshownin dotted lines and in its normal position by full lines; Fig. 3, a front elevation of the bracket of the separator-bar, parts of said bar, the separator-rod, its adjustable collar andadjustable foot; Fig. 4,a leftside elevation of the socket-piece which is carried by the separator-rod; Fig. 5, an isometric View of the bracket which forms a lockhinge with said socket; Fig. 6, an isometric View of the upper part of the adjustable foot of the separator-rod; Fig. 7,an isometric view of the lower part of said foot; Fig. S, an isometric view of the bracket or stand which guides the separator-rod; Fig. 9, a side elevation of either of the anti-friction rolls, one of which raises the separator-rod,while the other raises the lifting-rod; Fig. l0, a front elevation of the last-named anti-friction roll and the stud which carries said roll; Fig. ll, a side elevation of a collar arranged between said anti-friction roll and the nut which holds the stud upon which said anti-friction roll turns in the cross-shaft arm.

The roller-beam A, thread-board B, hinged to the roller-beam, ilnger-boards B', hinged to the thread-board, the yarn-guides or pigtails i), secured to the finger-boards, the ringrail C, the lifting-rod c, guided in the spindlerail D and the lower orguide rail E, the lat-ter serving as a step-rail where the spindles have an upper and a lower bearing, the cross-shaft F, turning in brackets f, secured tothe guiderail E, and caused to rock bythe usual means and provided with the cross-shaft arm f', the free end of Which carries a horizontal stud f2, on which turns an anti-friction roll f3, said roll being arranged under and supporting a lifting-rod c, the spindles G, their rings g, their bearings g', and bobbins H, are all of the usual construction and operation as used in ring-spinning machines. The yarn y descends from the drawingrolls (not shown) through the yarn-guides, and thence through the travelers c', which run on the rings g, secured to the ringrail C in the usual manner, and is wound in cops Y on the bobbins H or on cop-tubes in the usual manner.

For economy of space the spindles are set as near together as possible, and the yarns being wound on adjacent spindles are thrown outward by centrifugal force and are apt to strike each other and be broken, the tendency of the yarns to strike each other being greater the lighter the travelers and the greater the speed of the spindle. It is therefore customary to use separators or thin sheets or blades of metal in spinning-frames run at a high rate of speed, the yarn striking the separators and IOO being thereby prevented from striking each other. The yarns when flying outward, when free to do so, describe the surfaces of imaginary inverted balloons, the balloons being largest when the ring-rail is in its lowest position and the yarns being in the greatest danger of striking each other at the largest horizontal diameters of the balloons so de scribed and the larger diameters of said balloons rising` as the ring-rail rises. Separatore permanently afiixed to the ring-rail cause the ring-rail by their own weight to sag between the lifting-rods, ot' which there are two or more to each ring-rail or section thereof, requiring the ring-rail to be made strougerand therefore heavier.

Separators movable independently of the ring-rail but in some cases receiving a part of their motion from the ring-rail have been used. These are liable to bend the ring-rail between. the lifting-rods and retard the ringrail when they first come in contact therewith and make uneven cops. Such movable separators are commonly pivoted back of and above the ring-rail and are swung out of the path of the ring-rail when the latter is in or near its highest position, there being less need of separators at such times, and are commonly so narrow vertically, in order that they may not strike against the th read-board and rollerbeamsin rising, that the yarns interfere above and below the separators when in working position. The yarn frequently catches on the ends of the separators when the separators are leaving and returning` to their working position.

Separators which cannot be moved out from between the spindles are in the way during` the operation of dolliug. The separators described below obviate these objections. The separators proper I are of sheet metal and are secured to a separator-bar J, which extends back of the ring-rail parallel therewith and is provided with as many brackets K as there are separator-rods N, (hereinafter described,) each bracket K being secured to the separator-bar J, as by screws 7e, and having laterally-projecting pins 7a k2, the pin k being parallel with the axis of said bar Jr and entering a backwardly-iuclined slot Z, having a halfround lower end in the top of the socket-piece L and serving as a pivot on which said separator-bar J may be given a partial revolution about the axis of said pin 7c to raise the separators out of the way before do'fling and te restore them to position afterward. Each socket-piece L is provided in front of the inclined slot l with a curved projection l', the curvature of which is concentric with the rounded lower front end of the slot l and at a distance from said lower end of said slet equal to the space between the pins la 7a2, so that when the separators are turned down into the position shown in Eig. 2 the pin 7.52 rests upon a shoulder Z2, arranged on the frontof the socket-piece atthe lower end of the projection l', which prevents the sepalroll f3 above referred te.

passed through a slot f"in the cross-shaft arm rators going below a horizontal position. Each socket-piece is provided with an upwardlyprojecting stop Z3, preferably cast in one piece with said socket-piece, arranged back of the slot Z, and adapted to be struck by the separator-bar .l when the separators are turned up from between the spindles to prevent the further backward movement of the separators and to support them in their raised position, the center of gravity of the combined separater-bar and separators being at this time a little back of the axis of the pivot-pin k. When the separators are in their horizontal position, the projection Z and the backward inclination of the slot Zprevent the separatorbar from being disengaged from the socketpiece; but when the separators are in their raised position thcseparator-bar maybelifted, drawing the pivot-pins out of the inclined slots, and removed, with the attached separators, from the machine -for repairs or for other purposes.

Each socket-piece L is provided with a collar ll, adapted to receive and fit the upper end of a vertical separator-rod N, and is held in place on said rod by a set-screw l5, which turns in said collar and thrusts against said rod. There are as many separator-rods as there are lifting-rods, and each separator-rod is guided vertically, sliding in the sleeves m fm of the stand or bracket M, secured to the guide-rail by bolts m2, as shown in Fig. l, and is raised precisely as a lifting-redis raisedthat is, by the rising of the cross-shaft arm f', the stud f2 being lengthened and projecting backward through said arm to support an anti-friction roll f4, which is a duplicate ot' the The stud f2 is up to a stationary annular shoulder f6, with which said stud 'is provided, and a nut f7 is turned up on the said stud against the opposite face of said arm in the usual manner. One of the anti-friction rolls is retained on said stud between said shoulder]0G and the head of a screw f8, (shown by dotted lines in Fig. 10,) which enters a threaded hole in the end of said stud, also in the usual manner,and the other of said rolls is retained on said stud by the nut above named and another nutff, which turns on the reduced and threaded other end flo of said stud, collarsfuf12 being arranged between said last-named roll and saidnuts to lessen friction.

Each separator-rod is provided with an ad-v justable foot O, formed in two parts 0 o', the upper 0 of which (see Fig. 6) has a collar o2 integral therewith, which yreceives the lowei` end of the separator-rodN and isheld thereon by a set-screw o, which turns in said collar and thrusts against said rod. The lower part o of the foot (see Fig. 7) is an angle-piece, the horizontal portion o3 of which is arranged above the anti-friction roll f4 in a position to be raised by the rising of said roll. The parts o o are each slotted vertically at oG 07, and are secured to each other by IOC' IIO

a bolt o, passing through said slots, and a nut o5, turning on the threaded end of said bolt against the lower part o of said foot. The parts of the foot are prevented from turning on each other by vertical ribs on their contiguous faces, the ribs om on the part o being arranged to enter between the ribs o on the part o. By loosening the nut 05 and adju sting the parts of the foot vertically on cach other the highest point of the traverse of the separators is varied or the lowest point of said traverse; but the lowest point is preferably determined by an adjustable colla-rl), which slides on the separator-rod N and is held at any required height by a set-screw p, said collar by striking the top of the bracket M preventing any further downward move-` ment of the separator-rod. rlhelargest diameter of the balloon described by the yarn between the traveler and the yarn-guide or pigtail ot' course has a much less traverse than the ring-rail, being above the ring-rail when the ring-rail is down and and never rising as high as the guide-wire, the largest diameter of theballoon diminishing as the ring-rail rises and rising more slowly than the ring-rail rises; but it is not sufficient that the separator should separate the yarns merely at the largest diameter of the balloon, because if the separator is too narrow-aa for instance, if it were a single horizontal wire-the yarns would on a long traverse interfere above and below the separator when the balloons were largest. The separator in practice is therefore adjusted to stand between the largest diameters of adj acent balloons and is wide enough to extend above and below such largest diameters fora sufficient distance when the ring-rail is at its lowest position and to rise with such largest diameters until the ring-rail has reached its highest point. The fact that the separators above described do not in their usual operation swing upward upon pivots enables them to be of much greater width vertically than the vertically-swinging separators commonly employed-at least twice as wide as such swinging separators. The increased width of the separators allows of a shorter traverse of the separators and prevents the yarn from interfering above and below the separators when the ring-rail is in its lowest position and the balloons are largest. The use of wider separators enables longer cops to be spun. The backward inclination of the slot Z, the curved projection Z and its distance from the lower end of said slot, and the shoulder Z2 hold the separator-bar very securely in the horizontal position of the separators.

The separating devices above described can be used equally well in spinning either warp or filling.
