APPARATUS BEAMIING YARN Wilhelm Reiners, Gladbach-Rheydt, and Gustav Kahlisch, Rheydt, Germany, assignors to W. Schlafhorst 8g 00., Gladbach-Rheydt, Germany, a corporation of Germany 1 Application January 21, 1925, Serial No. 2,28 In Germany April 9, 1934 8 Claims. (CI. 28-32) Our invention relates to an apparatus for S m l r to Figure 2 d ow the third embodibeaming yarn and constitutes a further improvee a d, r ment of the beaming apparatus described and Figure is a detail of Figure 4 in vertical secfilaimedin our co-pending application for. Letters tion. s. f r 6 Patent Serial Number 606,240. In all these figures, 3 denotes the thread guide 5 In beaming slippery or very delicate yams, comb, which, together with its traversing cam 5,

In order to avoid this, the two 45 embodiments of the sameare illustrated scheend sections 3b of the comb may have fixed to 1 matically in the accompanying drawing by way each of them an arm d which by a pin e engages of example, in which! a in the bifurcated end i of an arm I, see Figure 3 Figure 1 is a side elevation with parts insection The two arms I are mounted on a shaft 9 which of a beaming apparatus according to the'invenis carried bythe arms 6 and is therefore coupled 50 tion and represents the first embodiment thereof, with the shaft carrying the comb carrier 11, so

a Figure 2 is atop view of Figure 1, fthat the arms 6 execute an upward motio Figure Bis a fragmentary top view similar to gether withthe guide comb, according to the FigureZ ahd shows the second embodiment, increasing diameter of the yarn body on the sli g is likwisea, fragmentary top view beam. In this manner the' two swinging end sections 3b of the comb, due to their being hingedly connected to the bifurcated ends i of the arms I and pivotally supported on the comb carrier 3a, are positively guidedduring the traverse of the comb in such a manner as to remain always separated by a little from the flanges b, b, whereby any contact whatever with the latter is prevented.

In the embodiment represented in Figures 4 and 5 the thread guide comb 3 extends in a continuous straight line and its two ends 31) are in the form of separate tubular pieces which surround the tube-shaped main portion of the comb and are under the action of springs (not shown) lodged within the main portion. These springs serve in known manner to guide the dents of the comb and permanently urge outwards the separate end sections 312. Stop pins ,1 fixed in the main comb portion and co operating with slotsprovided in the end sections 3b serve to limit the outward motion of the latter in accordance with the length of the comb traverse. The position of the guide comb shown in Figure 4 shows how the one end section of the comb is in contact with the respective flange 1), whereby the dents at this place adjust themselves correspondingly more densely, whilst the opposite end section is separated from its flange, so that here the marginalthreads run onto the beam in their normal spacing. In this embodiment two fixed stops it be provided, to prevent the resiliently mounted end sections 3b of the comb from gliding beyond the flanges b, b or touching them at all directly.

What we claim and desire to secure by Letters Patent is:-

1. In an apparatus of the class described comprising a flanged beam, a traversing thread guide comb having displaceable ends adapted to cause a reduction of the length of the comb when touching the respective flange of the beam during the comb traverse.

2. In an apparatus of the class described comprising a flanged beam, a traversing thread guide comb having displaceable ends adapted to cause a reduction of the length of the comb when touchingthe respective flange of the beam during the comb traverse, and fixed stopsadapted to cooperate with said comb ends like said ,beam 5 0 flanges with increasing diameter 01' the yarn body on the bealm body of the comb to placed inwardly as said comb traverses, to corn or traverse-limiting arms I may vertical pivots provided on the central comb portion, arms rigid with said end sections, stationary arms hingedly connected to said first-named arms and adapted to stop them together with said comb end sections so,as to prevent contact of the latter with said beam flanges.

' 5. In an apparatus of the class described comprising a flanged beam, a traversingthread guide comb of approximately the same width as the distance between the flanges of the beam, saidcomb having displaceable ends to allow the main body of said comb to reciprocate while the edges of the ribbon of the threads are confined within said flangesby inward displacement of said ends.

6. In an apparatus of the class described comprising a flanged beam, a traversing thread guide comb of approximately the same width as the space between the flanges of the beam, the ends of said comb being movable with respect to the allow said ends to be disflne the ribbon of threads within the flanges of the beam.

7. In an apparatus of the-class described comprising a flanged beam, a thread guide comb having displaceable ends adapted to reduce the length of said comb, means for traversing said comb, and means for displacing each of said ends inward and outward as it approaches and recedes from its adjacent flange.

1 8. In an apparatus of the class described comprising a flanged beam, a traversing thread guide comb having separate end sections mounted on vertical pivots provided on the central comb portion, and means connecting said end sections with a non-reciprocating part of the machine to cause said end sections to swing back to avoid contact with thebeam flanges.
