1 Claim.

This invention relates to ring spinning and ring doubling machines operating with either the spindle rail or the ring rail moving.

With ring spinning and ring doubling machines it is known that in the course of the operation for building the cop the ring rail moves up and down, whereas the spindle rail descends only. Further arrangements exist in which the cop building operation is elected While either only the ring rail or the spindle rail moves. Consequently the build of the cop depends to a great deal upon the movement of either the ring rail or the spindle rail or of both said rails respectively.

If the movements of these rails are swerving the uniform build of the cop is impaired. On the other hand care must be taken that the relative position of the spindle rail and the ring rail remains unaltered in the horizontal direction. In any event all the spindles must be concentrically arranged with the associated spinning rings at all times in spite of the rails moving in the vertical direction. Also the parts for moving the spindle and ring rails must be suitable for use in spinning mills by being extremely simple and strong.

With a View to satisfying these requirements it is indispensable that precise movement for the rails is ensured by means of strong guides. As guide members mostly round rods or tubes are used which are rigidly connected with the movable rails or are secured to the intermediate shields of the machine frame.

This simple construction has the drawback that in the guide bores which for the reasons mentioned above must be provided with only a slight amount of clearance, dust, fluff or other foreign matter is likely to accumulate, thereby inviting jamming or even seizing (stoppage) of the movable rail. Apart from this the slight amount of clearance allowable for the guide bores requires perfect parallelism between the guide rods in consequence of which the construction of the machine is considerably complicated. Due to the fact that the floors of spinning mills are usually susceptible to changing their original form by extraneous influences, frequent jamming is liable to occur in the machine, whereby the movement of parts may be stopped and eventual deformations of the rails may ensue. The drawbacks referred to are also present to a like or similar extent in slot guides cooperating with guide pins.

In order to eliminate the drawbacks referred to in ring spinning and ring doubling machines operating with either the spindle rail or the ring rail moving, according to this invention `the movable rail is displaceable by means of open slide guides which are arranged on the machine frame and against which the rail bears by the action of its own weight.

By this means the movable rail is associated with an open, that is, a bed-like exposed guideway positively preventing jamming or seizing of the rail. In this arrangement the movable rail is adapted to evade obstructions that may block the sliding surfaces by lateral shifting movement without deviating from horizontal position. Furthermore, fluff, dust or other foreign particles (even such that are hard to remove) are prevented from adhering due to the fact that the rail bears against the sliding surfaces without play, so that these surfaces are automatically cleaned during each throw of the rail. Moreover, the arrangement according to the invention has the advantage that the guide-ways of the rail are not influenced to any great extent by deformations of the floor on which the machine is mounted.

In the accompanying drawing an embodiment of the invention is illustrated by way of example only, in which Fig. 1 shows an elevation of this embodiment;

Fig. 2 is a cross-section thereof, and

Fig. 3 is ahorizontal section lon the line III--III in Fig. 1.

Only the parts necessary for explaining the invention are shown in the drawing.

The numeral I designates the spindle rail or the ring rail, as the case may be, the rail being provided with two longitudinal parts rigidly connected to each other by cross-pieces 2. Each cross-piece 2 is provided adjacent to each end thereof with a laterally extending bored projection 3 for engagement with one end of a flexible suspension member 4, for example a rope. Each suspension member 4 passes over a sheave 5 and is connected at its second end with a control member 5. The cross-pieces 2 cooperate at their end with open slide guides 6 laterally arranged on connecting Webs or partition walls 1.

The sheaves 5 are so located relative to the points of attachment formed on the rail l by the bored projections 3 that the suspension members 4 extend upwardly somewhat oif of the vertical, in such manner, that the rail l bears against the sliding surfaces 6 by means of the cross-pieces 2 by action of its own weight and is thus longitudinally guided. The rail is further presented a second sliding surface which is formed by the edges of the partition walls 1 and extends perpendicularly to the exposed sliding surface 6 cooperating with the respective longitudinal part of the rail, so that the rail is guided in the transverse direction also.

What I claim is:

Ring spinning and ring twisting machine comprising a frame formed with open slide guides, rails mounted for movement during the working of the machine along said slide guides on the frame, obliquely disposed rail supporting members, support rollers, said rails being forced against said guides by the oblique pull transmitted by said support members through the agency of said support rollers by a component of the weight of the structure per se.
