WEFT TENSION AND LOOM STOPPING DEVICE Original F iled Oct. 14, 1938 WODD/il/F F T 50L Ll VA IV.

Original application October 14, 1938, Serial No.
Divided and thisapplication March 15, 1939, Serial No. 262,044
10 Claims.
scribed in my original application, filed October 14, 1938, Serial No. 235,044, entitled Shuttleless loom, and this case disclosure is a division from said application, Serial No. 235,044.
An object of this invention is the provision, in a loom, of a novel and efficient device, whereby the loom will be stopped in the event there is a notable lessening of tension on the filling at any time, or if the filling should break. This would eliminate the possibility of broken picks, which condition is not ordinarily solved. I
Another 'object is the provision of efficient means for accurately regulating the tension of the filling, whereby the tension of said filling is at all times constant, resulting in every pick being inserted under identical conditions, whereby a more uniform weave is produced.
A further object of the invention is the elimination of cop or quill winding and the substitution therefor of cone Winding, which results in a very considerable lower operating cost, as well as investment. 7
With the foregoing and other objects in view,
tions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.
In the drawing:
Figure 1 is a view in elevation of the large fill- Figure 5 is an enlarged fragmentary view of the tension device. 7
Referring to the drawing, in which I have shown the preferred embodiment of my invention, it is to be understood that in supplying the filling l'to the loom, I provide a large filling cone 2 supported preferably upon a suitable bracket 3. This cone 2 can carry any desired filling, and will carry a great amount of filling, producing a supply of filling far in excess of that which the shuttle is capable of carrying in an ordinary loom. Therefore, it will be seen that my loom will-operate a comparatively indefinite period before a new supply of filling is required. The filling I is threaded through the tension device 4, thence to the eye 5 mounted in the outer flange 6 of bracket 1. The filling I is then threaded through the inner tube 8 of the inserting device fully shown and described in my copending application, Serial No. 235,044.
The tension device 4 comprises the base brack et 9 which is fastened to a support or the floor by means of bolt l0. This base bracket 9 is provided with an upstanding portion ll. Extending near the upper end of extension H are the stationary tension fingers I2. The fingers l2 are provided on their outer ends with a turned down portion I3, and intermediate their ends they are provided with notches or upwardly bent portions l 4. An auxiliary bracket I5 is fastened by screws.
l6 (Fig. 3) to the upstanding portion H of bracket 9. Auxiliary bracket I5 is suitably insulated from bracket 9. Auxiliary bracket I5 is substantially Y-shaped in structure (Fig. 2) producing bearing yoke H. The ends of this yoke l1 form hearings in which rotary pin I8 is mounted. On pin [8 is fixedly secured sleeve 19. Projecting from this sleeve is are the tension eye fingers 20. Each finger 2D has a downwardly extending portion 2! on which'is formed an eye 22. The end tension finger (Fig. 5) has a long downwardly extending portion 23 which is bent at right angles at 24. A collar 25 is fastened on one end of pin !8 and extending from this collar 25 is threaded rod 26. On rod 26 is adjustable nut 2'1.
is electrical lug connector 3|. Without depart- I ing from the spirit and scope of this invention, porcelain eyes may be substituted in place of the eyes 22, etc.
It will, therefore, be seen that the filling i, from cone 2, passes through the wool tension roll 32 (Fig. 1) held in a coil-spring-like bracket 33; the lower angle end of bracket 33 is fastened to the uprightportion l by means of a screw 34. From the roll 32, the filling enters the tension device 4, passing under astationary finger l2 and then through eye.22 of the contiguous finger 20. This sequence of the passing under one and then throughthe eye of the other tension finger continues until the filling l leaves the last tension finger, from which it goesto the eye 5, and then is threaded intothe tube 8 (Fig. 4) Due to the interlacing of the filling between the stationary tension fingers and the rotatable or. eye tension fingers'zll and the tendency of the adjustable nut 3'! to take up slack on the upper tension fingers, a tension maintained on the filling I which may be adjusted as desired by using more or less l trical circuit, which in turn will cause the loom to stop through the usual method of stop motion control of the warp stop motion. This device will also function similarly should the filling become broken. Of great importance is the fact that every, insertion of the filling in the weaving operation will be under practically identical tension, thus insuring a perfect filling tension condition, which will be reflected in a superior woven fabric.
While I have described the preferred embodiment of my invention and have illustrated the same in the accompanying drawing, certain changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
