W. SCHWElTER WARPING FRAME Filed June 13, 1930 2 Sheets-Sheet 2 Patented Jan. 17, 1933 UNITED STATES WALTER SCHWEITER, 0F HORGEN NEAR ZURICH, SWITZERLAND WARPING FRAME Application filed June 13, 1930, Serial No. 461,008, and in Switzerland June 26, 1929.
The invention relates to warping frames of the class in which the threads are unwound from vertical, horizontal or inclined fixed or revolving bobbins, such as bottle bobbins, spools, straight bobbins, or the like.
The invention has for its object means which in a very simple manner permit regulation of the additional tension of the threads in unison or in groups even during the warping operation. This object is achieved primarily by the fact that the thread guides arranged in the direction of motion of the threads behind the stationary bra-king devices are displaceably arranged in the longitudinal direction of the frame in such a manner that by this displacement an additional regulation of the tension of the threads is made possible. By mounting the thread guides of one series for instance on a common bar which can be shifted in the longitudinal direction of the machine and fixed in the shifted position, the way of the threads from the bobbin over the brake disc to the separator can be altered in a very simple manner by shifting this bar and the tension of the threads can be regulated thereby additionally.
I am aware of the fact that arrangements are already known in connection with winding frames in which the thread guides can be displaced relatively to one another, while with warping frames, ball brakes have been proposed between two neighboring thread guides, the entrance and outlet openings for the thread of the ball cages of these brakes being adjustable relatively to the direction of the thread. Braking devices of this type require great attention in attending and much time, since each individual brake must be ad justed separately while, on the other hand, there is scarcely a possibility to adjust the brakes during the warping operation.
In order that the invention can be more readily understood, an embodiment of the same is illustrated by way of example in the accompanying drawings in which Figure 1 is an end view and Figure 2 a front view of the arrangement,
Figure 3 is an elevation and Figure 4 a plan view thereof;
Figure 5 illustrates the front end of the warping frame, seen from the top and on a reduced scale.
Referring to these drawings, 1 denotes the creel on the longitudinal bars 4 of which are mounted bottle bobbins 5 on pins 2. The bars are inclined and rest on supports 3. Other supports 6 of the creel have mounted on them arms 7 which carry eyes 8 corresponding to each series of bobbins, and a longitudinal bar 9 that carries brake discs 10 between which the thread 11 is braked in known manner. The braking effect can be regulated by weights 12 acting on the upper discs 10. Each pair of brake discs is fixed on an inclined lap plate 13 mounted on bar 9 and adapted to introduce the thread 11 coming from the eye 8 between the brake discs or to cause the thread to be automatically drawn thereinto in a new warping operation, after the machine has been stopped.
On the arms 7 is longitudinally shiftably mounted for each series of bobbins a bar 15 that extends on the whole length of the creel and carries thread guides 14, which bar can be fixed in shifted position by means of pins 16 or the like that engage corresponding holes 17.
By displacing the thread guides relatively to the brake discs 10 which is eflected in a very simple manner by shifting the bars 15, the tension of the threads can be regulated within certain limits, which regulation can be done before the warping operation is commenced or eventually during operation.
The pins 16 can of course be replaced by clamp screws. Furthermore, in lieu of the inclined bobbins illustrated vertical or horizontal ones can be provided for. Finally, all of the bars 15 which carry the thread guides 14 can be positively coupled with one another by suitable means, so that all thread guides 14 can be adjusted in unison.
What I claim is In combination with a warping frame, a plurality of stationary braking devices for the threads each comprising a pair of brake discs between which the thread is designed to pass, fixed guide eyes cooperating with each of said braking devices for introducing the thread to said braking devices, thread guides- .100
arranged behind each of said braking devices in the direction of motion of the thread, and means for displacing said thread guides in cups in the longitudinal direction of the me to vary the angular extent of contact between the thread and brake discs to obtain an additional regulation of the tension of the thread.
The foregoing specification signed at Zurich, Switzerland, this 31st day of May, 1930.
