To aZZ whom it may concern:

Be it known that I, ALEXANDER GLAVEL, a citizen of the Swiss Republic, and resident of Basel, Switzerland, have invented a new and useful Apparatus for Smoothing Hanks of Textile Materials, of which the following is a full, clear, and exact specification.

In the United States Letters Patent No. 972060 dated October 4, 1910, is described an apparatus for smoothing hanks of textile materials, especially hanks of dyed silk, comprising a suspending roller upon which the hanks are to be suspended, a device for imparting to the suspending roller a stepwise rotation on its own axis, a vertically movable stretching roller arranged beneath the said suspending roller, a lifting rod at-- tached to the said stretching roller, and a rotating engaging fork and two guides placed one on each side of the lifting rod, the said engaging fork being so placed with regard to the lifting rod and to the said guides, that the fork in the course of its rotation passes between the said guides and that during this passage its limbs are pressed against the lifting rod frictionally by means of the said guides, whereby the lifting rod together with the stretching roller is lifted, and, after the passage of the fork limbs between the guides, is allowed to fall down again.

The object of the present invention is to substitute in the said apparatus for the engaging fork with elastic limbs and the two guides placed one on each side of the lifting fork a lifting device rendering the operation more secure and the strength of stroke of the stretching roller considerably more regular than it is possible with the device described in Letters Patent No. 972060. This improved device consists of a rigid, vertically movableengaging fork and a clamping wedge serving to fix the lifting rod temporarily into the said fork under the action of a pressure lever and of a rotary cam, in such a manner, that in the course of the rotation of the said cam, the lifting rod is raised by the latter with the fork and allowed to fall down again.

The drawing illustrates by way of example one form of carrying out the invention.

Figure 1 is a vertical section. Fig. 2 is an end view and Fig. 3 is a horizontal section of the improved lifting device of the apparatus. Fig. 4: shows the apparatus in its entirety.

As in Letters Patent No. 972060 there is mounted in the machine frame 1, an upper suspending roller 2 (Fig. l) upon which the yarn hanks are suspended, while beneath this suspending roller there is mounted the stretching roller 3 which is movable in the vertical direction and constitutes a beating device. Both rollers are loosely and rotatably mounted upon their axes. The suspending roller 2 is provided with a ratchet wheel 22 (Figs. 1 and 2) which on every stroke of the stretching or beating roller 3 is moved forward to a predetermined extent, in a known manner, through the medium of a pawl 20 in order to feed the yarn hanks intermittently forward. The pawl 20 is attached to a bent lever 21 fixed on a rocking shaft 22 bearing an arm 23 provided with a roller 24: held in contact with a rotating cam 25 by a spring 26 pressing against a finger 27 of the said shaft 22. The actuation of the stretching or beating roller 3 is effected in this case in a manner differing from that in Letters Patent No. 972060. The stretching or beating roller 3 is mounted upon a vertically movable lifting rod 4 which at the upper end passes through a rigid fork 9 (Figs. 1 to 3); the latter is freely movable in the vertical direction and its lowermost position is determined by a stop 10 (Fig. 1). Between the limbs or prongs of the fork 9 there is arranged a clamping wedge 11 and a pressure lever 12 is pivoted thereto. The latter is under the action of a rotating cam 13.

Assuming the parts are in the position shown in Fig. 1, when the cam 13 rotates in the direction of the arrow, Fig. 1, the lever 12 is first so turned that its inner end or tail presses the wedge 11 tightly against the lifting rod 4 and thereby rigidly holds the latter in the fork by its clamping action, so that the further rotation of the cam 13 by its continued action upon the lever 12 raises the latter together with the fork and the lifting rod 4 until the said cam 13 releases the lever 12 and wedge 11, whereupon the rod 4 drops with the stretching or beating roller 3. As is obvious from Fig. 1, the stop 10 is adjustable in the vertical direction by means of the bolts 15. This enables the extent of drop of the fork 9 to be accurately regulated, since, the stop 10 determines the lowermost position of the fork Which is freely movable in the vertical direction.

What I claim is:

1. In an apparatus for smoothing hanks of textile materials, especially hanks of dyed silk, a suspending roller upon which the hanks are to be suspended, a device for imparting to the suspending roller a stepwise rotation on its own axis, a vertically movable stretching roller arranged beneath the said suspending roller, a lifting rod attached to the said stretching roller, a rigid, vertically movable engaging fork and a clamping Wedge allowing to fix frictio-nally the lifting rod temporarily into the said fork and subjected to the action of a pressure lever and of a rotary cam in such a manner that in the course of the rotation of the said cam the lifting rod is alternatively fixed frictionally into the said fork by means of the said clamping Wedge, pressure lever and cam, in order to raise the lifting rod and the stretching roller together with the fork, and allowed to fall down again.

2. In an apparatus for smoothing hanks of textile materials especially hanks of dyed silk, a suspending roller upon which the hanks are to be suspended, a device for imparting to the suspending-rollera stepwise rotation on'its oWn axis, a vertically movable stretching'roller arranged-beneath the said suspending roller, a lifting rod attached to the said stretching roller, a rigid, vertically movable engaging fork, having its lowermost position determined by an adjustable stop, and a clamping Wedge allowing to fix frictionally the lifting rod temporarily into the saidfork and subjected to the action of a pressure lever and of a rotary cam in such a "manner, thatzin the course of the rotation of the said cam, the lifting rod is alternatively fixed frictionally into the said fork by means of the said clamping Wedge, pressure lever and cam, in order to raise the lifting rod and the stretching roller together With the fork; and allowed to fall down again. y

In Witness whereof I have hereunto signed my name this 27th day of March, 1912, in the presence of two subscribingwitnessesr V ALEXANDER CLAVEL. Witnesses:
