SAILER RING SPINNING AND TWISTING MACHINE Filed June 22. 1932 Patented June a 13, 1933 seam simian, or srrr'rgreanm, ennMA RING SPINNING A D'EwIs r'ING AoHINE Application filed Jam 22, 1932, Serial noa eiaraa aaa ia eerman adae 2 6, lean i In point of the cop length to be produced the ring spinning and twisting machines at present in use are restricted-to pretty small limits mainly determined by the lowest position of the ring frame and by the position of the thread guide loop. Also, according to experience, the balloon arising in spinning is not to exceed a certain size as otherwise the air resistance and the centrifugal power of the twisting thread parts would cause undesired tensionsfwhich could be obviated only by reducing the number oil-evolutions of the spindle. But by such measures the produc tion is decreased accordingly which is nadmissible. On the other hand the balloon,

while spinning, is to have a size more or less constant in order that there may be nearly the same drawing conditions and that the tearing strength ofthe yarn may remain uniform at the be inning as well as at the end of the cop. i y

In orderto meet these conditions it has been tried to let the ring frame in ring spinning machines, when the thread guide loop is at astandstill, go up and down only as high as the winding strokeand tolower the spindles according to the increasing cop. Other constructions regulate the cop by means of exclu sive movement of the flyer or spindles. But

. cording to the positionggof the ring frame w hich merely Carries outthe windingstroke. 1 ("lons'equently ita ispo sible to linishlthecop Pat whilst of course its constant size isachieved A y therefore poss le'to in the second case. In consequence of the large balloon these machines are not very suitable for producing large cops, becauseof the very frequent thread slippings while working. It is also known to adjust the thread guide loops also upwards in certain reduced proportion to the upwards moved ring frames and rings with stationary spindles. In the initial stage, when producing large cops, a large balloon is also obtained which constantlydecreases towards the end of spinning. But in this case the equilibrium is distributed throughthe constant decrease of the balloon, and the thread guide loops cannot be driven upwardsat pleasure because the angle of the thread-course soon assumes unfavor able dimensions in view of the drawing frame.

ning. Guides 8 are fixed in parts 3 of frame 12. These guides 8 are holding the adjustable thread guide carriers 13 of the thread guide rail 14 to which loops 15 are fixed. Spindle rail 9 is provided with holders 16 with which rods 17 are adjustably connected. The latter are supporting head 18 of carrier 13 and with it the thread guide rail14 and the loops 15. The carriers 13 are also provid'edwithv an adjusting ring 4.

When spinning is started the machine is in the position of Fig. 1. The spindle rail 9 is at the top and, by means of holders 16 and rods 17, holds the thread guide loops 15 with:

rail 14 and its carriers 13 at the height of the drawing frame 19. VVit-h the increase of the cop all these parts are descending until the adjusting ring 4 touches the guide tube 8 above part 3. At this moment the downward movement of the thread guide loops 15-ceases while spindle rail 9 with spindles 2 sinks further (Fig. 2). During the whole time the the spindle rail is raised to its initial position, the rod engaging the head operating to maintain the thread-guide rail in spaced relation to the spindle rail during the first part of the downward movement of the spindle rail and until the adjustable stop on the head extension engages the upper end of the fixed vertical guide.

In testimony whereof I have signed my nameto this specification.

ring frame makes a movement within the limits indicated at h, Fig. 2, to perform the winding stroke proper. The raising and lowering of the spindle rail and of the ring frame is eflected by known means such as stroke rods or chains in connection with rollers or toothed wheels or toothed bars.

I claim 1. In a cop-winding apparatus, the combination of a vertically movable spindle rail, with a vertically movable thread-guide raih a fixed vertical'guide, ahead slidably mounted'on the upper end of the fixed vertical I guide to engage the under side of the threadguide rail, means limiting the downward movement of the head on'the fixed vertical guide so that the downward movement of the thread-guide rail coincides with the initial downward movement of the spindle rail, and a vertical rod'attached at its lower end to the spindle rail and with its upper end positioned to engage the head when the spindle'rail is raised to its initial position, the rod engag ing the head operating to maintain the thread-guide rail in spaced relation to the spindle rail during the first part of the downward movement of the spindle railand within the limits of the downward movement of the head on the fixed vertical guide.
