O. RECKE and W. G. H. PELTZER in RHEYDT. Innovations on ring spindles.

Patented in the German Empire on September 16, 1879.

The subject matter of the invention relates to an annular spindle.

Its construction is the following:

A steel spindle is with its lower end in a track bearing and at the top in a neck bearing guided; both bearings are combined in a cast-iron, tubular bearing body.

Between the two bearings there remains a cavity, which serves as an oil reservoir, so that the spindle with its two bearings is continuously in OeI.

Above the upper bearing at A , the cast iron sleeve is somewhat widened in order to be able to hold an oil reserve in this widening for the neck bearing.

The thrust bearing is either direct or through a bore in the cast iron one of the two types described below.

1. Fig. 6. A cylindrical sleeve rolled from nickel silver or other sheet metal with an oblique, open cut is pushed from below into the tubular base of the bearing body and is pushed into the tube by the bronze screw B, which also serves as a track plate pressed in until the locking surface of the screw rests on the material surface of the bearing body.

2. Fig. 5. The screw itself is drilled out correspondingly deep and serves directly as a footprint and guide bearings.

By these arrangements it is achieved that the foot screw, if the thread is sufficient is easy, must always lead conaxially to the bearing body.

In the first case, the access of OeI to the lower storey is through the fabric joint Tin box, secured in the second case by the fact that the hollow part of the screw is unilateral is cut open.

The whole sub-bearing construction can be removed for the purpose of cleaning the spindle, or if the Wear and tear become too great, removed and replaced.

The spindle receives the drive from a downwardly partially overlapping upper bearing Whorl.

By this construction it is achieved that the friction work and the wear are low Limits are kept.

The overarching whorl also serves to protect the oil from contamination Dust etc. ~

Connected to the neck of the host is a shell which forms the lower part of the coil while the upper part of the latter is guided on the spindle itself; there the spindle is free, the minimum radius of the coils becomes smaller with greater strength. For heavy, e.g. B. twisting spindles are to be arranged instead of the bowl plates with drivers.

It is also achieved that the yarns on paper tubes of smaller diameter can be spun.

The use of ordinary wooden edge spools shown in FIGS. 3 and 4b is also important in this construction, namely in two directions.
. First, the center of gravity of the rotating masses is moved closer to the bearings ^y and the spindle is thereby more secured against vibration, and secondly the yarn, which slides from the upper edge of the bobbin with a low relative number of revolutions, is deflected out of the direction of the cylinder side in the sense of rotation . As a result, the runner (traveler, runner) receives an acceleration which is greater than that of the previously common ring spindles.

This greater acceleration permits either the spinning of looser yarn, or but the use of thinner coils.

Due to the constant position of the rising yarn end, that of the centrifugal force is also determined of the ring counteracting radial component of the yarn tension less variable, d. H. the Wrapping itself more evenly. The type of spinning of these bobbins in conaxial cylindrical Layers allows the movement of the table to be maintained on winged throstles which are on the ring system of the inventors are to be rebuilt, thus enables a relatively easy conversion.

With these coils, too, the inner diameter can be assumed to be smaller than is necessary and common with the winged throstles, but this achieves that on one More yarn can be spun on a bobbin with the same outer diameter and the same stroke can before it needs to be removed, or else that one has to

Claims (2)

A correspondingly higher number of spindles can be installed in a bank of a given foot length by changing the outer diameter with a constant quantity of yarn, quite apart from the fact that the spindle construction has a significantly greater height of the edge bobbins, i.e. H. allows a larger amount of yarn per spindle compared to the previously common toroidal bobbins with a smaller free spindle length. Deviating from the methods of fastening the coils on the spindle or of paper and other sleeves on the spindles by means of inserted metal or wooden sleeves, with or without a lower edge, the inventors operate common edge coils of any kind, as well as cylindrical ring coils fixed or clamped lower edge, furthermore metal or wood lining with just such an edge for spinning on paper or other sleeves through a friction disk attached above the inn, similar or as shown in FIGS. 8 and 9. This ensures that when the yarn tension is greater, the bobbin can slide on the spindle, i. H. over-tensioning of the yarn is avoided. In this way, yarns made of lesser material or those with a looser twist per unit of length can be spun down to the weft yarn on the spindle without fear of thread breakage. The use of the rotation of the bobbin by means of friction from the spindle allows for an easy conversion of existing wing throstles, spinning and twisting machines to ring systems with complete or partial preservation of the spindles with their bearings, in that only one plate and the spindle are detachably placed on the spindle neck event, needs to be shortened (see Fig. 7). With this construction, the bobbin does not need to be removed for the purpose of piecing or tying broken threads; it is rather sufficient to hold the bobbin up for a moment, pull the thread off in sufficient length, through the traveler and thread guide, and then join it with the drawn one Bringing roving or threads to be twisted. In all of the above-mentioned types of spindle construction, insofar as they relate to new spindles, the following device is attached so that the spindle, which has been tilted as a result, can be placed vertically again when the upper or lower bearing is worn. A small pressure screw goes through the spindle table under each spindle on the inner side. By screwing it in, the spindle, the bearing foot of which is a little beveled at the front for this purpose, tilts around the edge of this bevel and the inclination of the spindle caused by wear can be eliminated (see Fig. 9). Godfather ν τ claims: 1. The application of a centrically precisely guided, easy to remove track bearing. 2. The procedure for ring machines, the entrainment for edge and other ring bobbins etc. for twisted, weft and warp yarns to effect the spindle by means of friction disks made of felt or other material, whereby the spinning and twisting of yarn with any and very small wire is made possible.
