This invention relates to textile machines and is particularly concerned with machines for the twisting and winding of yarns, such as ring spinning, flier spinning and cap spinning machines.

In machines of this type the spindles are generally arranged substantially vertically, and the traversing of the yarn being spun upon the bobbins or other yarn packages is effected by the vertical movements of a lifter rail, which carries either the bobbins on which yarn is being wound or guide means for conducting such yarn to the bobbins. The lifter rail is actuated by means of vertical rods known as poker rods which carry the lifter rail on their upper ends and are vertically reciprocated in guides or sliding bearings, each rod having a chain attached to its lower end, the chain passing over a flanged wheel or chain sprocket and being secured to a horizontally reciprocating traverse rod. In a long machine, having many spindles arranged in line, the lifter rail may be divided into sections each carried by two such poker rods appropriately spaced from one another along the length of the lifter rail section.

According to the present invention a twisting and winding machine for the collection of a series of yarns comprises a series of vertical spindles, a horizontal lifter rail adapted to be reciprocated vertically for traversing yarn upon bobbins mounted on said spindles and a plurality of vertical poker rods for carrying and actuating said lifter rail, said rods being disposed in pairs along the length of the lifter rail, the rods of each pair being disposed at substantially the same distance along the length of the rail, one attached near the front edge and the other near the rear edge of the rail. The arrangement of the poker rods in pairs in this way gives more even support to the lifter rail and reduces any tendency to the deflection or distortion thereof, without increase in the moving weight, each of th pair of rods employed having approximately half the weight of a single rod as employed heretofore in the same position along the length of the rail but disposed in the middle of its width. It also allows the vertical run of the chain by which the rods are operated to be located centrally between the two rods, being attached to the middle of a yoke by which the lower ends of the rods are connected; this relieves the poker rods of the bending moment arising in previous constructions in which the chain is connected to a small horizontal projection extending laterally from the bottom of each rod. In addition, the use of a pair of rods permits them to pass one on each side of the spindle rail instead of passing through a hole formed in the middle of orporation of America,

the spindle rail for the purpose as when a single rod is employed. The spindle rail is the rail, generally non-reciprocating, carrying the rotating bobbins in cases where the lifter rail carries the thread guide means as in a ring-and-traveller device, or carrying the thread guide means where the lifter rail carries the bobbins as in cap spinning machines.

For the guiding of the pairs of poker rods poker rod slides or bearings must be provided, and the bearings of each pair must be parallel to each other within close limits in order that the poker rods may operate freely and accurately and without hesitation. The machining of the bearings with the requisite degree of accurate parallelism is apt to be expensive. It has been found however that a less expensive mode of construction may be adopted by providing for some freedom of lateral movement for one of the poker rods, the other being rigidly fixed at its upper and lower ends to the lifter rail and to the connection between the poker rods respectively. Thus the lower end of on poker rod may rest on an adjustable tappet passing through a yoke by which the rods are connected while the upper end of the rod has a bearing surface on which the lifter rail rests, lateral movement of th upper end with respect to the rail being limited to means of a spring connection between it and the lifter rail.

While the invention is applicable to twisting and winding machines of the difierent types referred to above, it is of particular advantage as applied to ring spinning machines for the reason that the lifter rail of a ring spinning machine,

having to accommodate in its width the diameter of a ring large enough to encircle a full bobbin, is generally made wider than a lifter rail in a cap spinning or flier spinning machine. In consequence the poker rods of each pair may be more widely spaced from one another and greater advantage is obtained in respect of the rigidity of the lifter rail.

In ring spinning machines, in which the yarn fed to the bobbin passes from a balloon-guide or cordingly, means may be provided in conjunction with the traversing arrangement of the present invention for raising and lowering the balloonguide in phase with the lifter rail so as to keep the balloon length constant or more nearly constant than if a stationary balloon-grime" employed. For this purpose the balloon=guides were" corresponding to the spindles of each section of a lifter rail may be mounted on a common guide" rail extending across and carried-by the upper f ends of two vertical rods slidably mountedin ver tical bearings, and actuatedby the same mechanism as the double poker rods described above;

Thus, each vertical rod can b'e dis pose'd'clos e to one of the pairs of poker rods carrying the lifter rail and can be driven by a nection from the yoke joining the poker rods. In order to deal with any slight link and lever con lack of parallelism in the vertical rods, thes'ect'ion of rail carried thereby may be divided in the middle and joined we ilexilol ingsli'ght play betweenthe two partsi H y ay of exarhple, one form of'riri'g spin'r'iin mac ine in accorda'ri'ce" with the pres nt inven:

The lower end of the balloon-guide actuating rod Ml is connected by means of a short link 52 to the mid point of the lever 50. In order to allow for any slight lack of parallelism between the two balloon-guide actuating rods 44, the balloon-guide rail 45 carried by them is divided at the middle into two parts which are held together by means of a flexible connection 53. By these means the balloon-guide 41 of each spindle is caused to rise and fall in phase with the ring rail 3!, though for a shorter distance.
