THREAD TENSIONING DEVICE FOR CREELS AND THE LIKE Filed May 15, 1933 Patented July 2, 1935 UNITED STATES THREAD TEN SIONING DEVICE FOR CREELS AND THE LIKE Albert Perichard, Tarare, France Application May 15, 1933, Serial No. 671,264 In France May 14, 1932 2 Claims.
(Granted under the provisions of sec.
14, act of March 2, 1927; 357 0. G.
The present invention relates to thread tensioning means, and more particularly as applied to creels and the likesystems used in the textile industry.
Such means are known wherein a thread to be tensioned travels between two plane surfaces pressed against each other. In one particular type, equal area surfaces are pressed by means of a weight displaceable on a lever, the said weight exerting its pressure equally on the total area of the contact surface.
In such arrangements, the disadvantages are many and produce on the threads injurious extensions altering the diameter of same. In fact, it is frequent that these threads have at the outset such faults as swellings due to the agglomeration of broken fibres, and other diameter irregularities. These, when acted upon by tensioning means described above, must overcome the total pressure exerted on the single upper surface, the result being an extension of the thread (with consequent diameter reduction) or its rupture.
Thus, tensioning devices having a single upper pressure plate, an invariable contact surface, and a pressure variation only are liable to the defects mentioned.
The present invention aims to overcome these difficulties by providing multiple surfaces, of light and invariable weight, the area of each of said surfaces being also invariable, whereby the pressure to each unit of area is consequently invariable.
According to the invention, the device is constituted by a single support surface of simple character provided with a flock surface, several light plates being hinged side by side to bear on this support surface and also provided with an inner flock surface adapted to contact with that of the support member.
As an example, and for purposes of illustration, a practical embodiment of the invention is shown in the annexed drawing, wherein:
Figure 1 is an elevational view of the device with one plate raised and shown in dotted lines,
and
Figure 2 is a plan view showing all the plates in operative position.
Referring to the drawing, numeral l indicates a supporting base having a flock surface shown at 2, and constituted by an animal skin with its hair attached. Another flock surface 2, similar to the first, is pressed thereover by means of plates 3 articulated at 4, a thread to be braked being passed between said surfaces. These plates 3 are subdivisions, the weight of which is in a ratio of or of the total weight applicable to the thread. Each of these segments can be lifted to an inoperative position shown at B, or left operative as at A (Fig. 1). The device is completed by guides 5 adapted to guide a thread 6 through the apparatus.
From the foregoing, it will be evident that various tensions can be imparted to a thread without stretching due to swellings and the like. Each plate being of minimum weight, it is possible for a swelled portion of a thread to lift slightly, and successively, each of the plates, thus preventing rupture and while still maintaining a desired tension.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes as to the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, what I claim is:
1. A thread tensioning device for creels and the like, comprising a supporting member having a flock surface, and a plurality of pivoted plates also provided with a flock surface adapted to contact with the first, a thread to be tensioned being adapted to travel between said surfaces.
2. In thread braking means, a stationary base member having a hair surface, a plurality of pivoted plates adapted to rest on said member, said plates having a hair surface also, and means for guiding a thread between said surfaces.
ALBERT PERICHARD.
