PAUL HAHN in NIEDERLAHNSTEIN a. Rh.

Patented in the German Empire on March 12, 1913.

In those previously known, essentially for hank yarn mercerizing machines with in the same horizontal plane mounted stretching roller pairs specific devices for Replacing the fleet troughs, in which the latter is initially at the same time in height and then moved horizontally, it can happen that, if irregularities in

. the mode of action or the onset of action

ίο the control devices mediating the trough movements occur - a possibility that can be traced back to the most varied of causes could be - pressed the troughs against the rollers and not just by them are destroyed, but also considerable damage to other machine parts can cause.

According to the present invention, this possibility is to be prevented and also a more compact arrangement and better accessibility to the thread rollers be achieved that one arranges lye and rinsing water trough on top of each other and short after using the upper trough - suitably containing the water - put the same in brings an inclined position from which it automatically moves on a pad, with towards the end of his movement he triggers a blockage that activates the lifting device of the lower Releases trough, so that this move in the height direction and also under the Rolling can kick, whereupon after some time the reverse sequence of movements both troughs put back in the first position.

An embodiment of the subject matter of the invention is shown in FIGS. 1 to .3 of the drawing illustrated in several working positions and has the following characteristics:

The rinsing water basin d, which is arranged below the pair of Gämwalzenpaares a, b and is mounted on wheels c , the sloping bottom of which is provided at the deepest point with a drain nozzle e , which is expediently connected to the drainage channel by movable lines, rests with its wheels on a pair of rails f which is bent upwards at both ends and is supported on the one hand by the tabs g of the rotatably mounted shaft h firmly connected to the latter, on the other hand rests on the upper arm o ^{2 of} a double lever 0 rotatable at η.

The lower arm ο ^{3 of} the lever 0 is equipped with a roller q that rolls over the circumference of the cam disk m; the upper rails f supporting arm ο ² of this lever under the influence of the weight or spring loading O ⁴ and so presses the roller q permanently against the periphery of the disk m. If q these roller for running onto the lying between the raised circumferential distances the circumferential parts of the disk m somewhat approximated to the axis I , the lever 0 executes a certain rotational deflection by η, as a result of which the pair of rails f with and on the lever arm o ² which supports it is lowered somewhat, i.e. it comes into a slightly inclined position (Fig. 2). The latter is enough to get the one on his wheels

to set the stationary flushing water trough slowly and automatically in motion, so it rolls along the inclined rail surface, on this down to near its ends. Towards the end of the trough movement, a stop p provided on the bottom of the trough d strikes a stop p located in its plane of movement, on the upper arm end o ^{2 of} the lever o about an axis o ¹ within small deflection limits

ίο rotatable spur s, whereby the continuation of the basin d is stopped, so this comes to a standstill on the inclined surface f (Fig. 2).

If, after the above-described displacement of the flushing water trough d, the roller q reaches further peripheral parts of the disk m, which are still closer to the axis /, the weight of the trough acting on the spur s gradually presses the spur around its axis o ¹ into a position directed towards the lowered ends of the rails f , with a pawl r , which is dependent on the rotational movements of the spur and rotatable about a pin χ, is carried along and therefore disengages from the locking gap ν located on a double lever t, t ¹ rotatable by η so that the lever arm t , which was previously prevented from rotating about η by the blocking and carrying the pin χ, swings downwards under the influence of a weight or spring force w acting on it, which results in a simultaneous lifting of the arm t ¹ . The pawl r , which can be rotated by χ, comes to rest at the same time as the spur s by resting against the surface of a stop r ^{1 of} the lever t (FIG. 3).

The arm t carries at its end the supports ζ connected to the bottom of the caustic basin y and, through cams k provided on it, a lever i loosely mounted around h , the end of which engages the other pair of supports j of the caustic basin. Accordingly, the latter will be ^; m lowering the lever arm t by t ¹ , i, k, z, j raised so far that the lower strand of the strand of yarn placed around the rollers a, b can dip into the liquor.

After the lye impregnation has ended, the lye basin y lowers under the influence of the cam k with the rolling up of the roller q on the peripheral parts of the disk m further away from the axis I with simultaneous rotation of the levers t, t ¹ and 0 and in the opposite direction as before returns to its previous position, lever t being locked again by knocking out the pawls r, s and the pair of rails f is lifted into its previous position so that the basin d can slowly and automatically roll back under the rollers. In this position of the basin d shown in FIG. 1, the rinsing of the strand of yarn ζ. Β. made by spraying rinsing liquid on the same in a known manner.

Claims (2)

Patent-to sayings: 1. A device for replacing the liquor troughs of Strähngarnmercerisiermaschinen with mounted in the same horizontal plane pairs of stretching rollers, characterized in that the rinsing water trough (d) located above the liquor trough (y) during rinsing for the liquor period by inclining its oscillating support surface (f) and under its own Weight pressure rolls or slides down the inclined path, thereby exposing the liquor trough (y) and triggers a lock (r, s) , which releases the lifting device for the liquor trough (y) to lift it into the area of the tensioning rollers (a, b) a control linkage (m, t ¹ , k, i, j, h, g), which after the lye impregnation also serves to lower the lye trough (y) , during which the swingable support surface (f) for the rinse water trough (d) by blocking the Lever (t) is brought back into the horizontal position by knocking out the pawls (r, s) so that the rinsing water trough (d) wi by slowly, automatic rolling back Either comes over the liquor trough (y). 2. Apparatus according to claim 1, characterized in that the support surface (f ) equipped with rollers (c) and carrying the rinsing water trough (d) is rotatable on the one hand about a fixed point (h) , on the other hand rests on a control lever / 0 ² J, the position of which depends on the respective position of a rotating cam (m) that controls it. 1 sheet of drawings.
