As shown in Fig. III the extensible portion 30 of the finger 29 has its free end downturned to project into a longitudinal slot 31 at the outer end of the stud 23 to constitute a movable abutment for the conical spring 26. The compressive force of the spring 26 may be varied by adjusting the extensible portion 30 of the finger 29, a set screw 32 being provided for this pu pose. Pinned to the rock shaft 28 immediately adjacent the front side of the bearing 27 (i. e. at the left of the latter in Fig. IV) is a vertical arm 33. At its outer end the arm 33 carries a porcelain projection 34 for engaging the yarn Y and angularly deflecting it between the pig-tail guides 18, 19 as shown in Figs. I and III. A third arm 35 is secured to the rock shaft 28 immediately adjacent the rear side of the bearing 27 (i. e. the right hand side of the latter in Fig. IV), said arm being angularly set on the shaft and having its outer end bifurcated as at 36 to accommodate a circumferentially grooved roller 37. Within the groove of the roller 37 rests a lever 38 which is freely fulcrumed at 39 to a laterally projecting lug 40 of the bracket plate 13. As shown in Figs. I and HI, the lever 38 is engaged by the pierced end 41 of an angularly configured link 42 whereof the opposite end is pivoted at 43 to an extension piece 44 fixedly attached to the weight 12 of the swinging frame 10 of the winding machine. By shifting the block weight indicated at 45 along the lower horizontal portion 42a of the link 42 it is possible to vary the downward pressure exerted by the outer end 41 of said link upon the lever 38.
To the inner end of the rock shaft 28 is affixed an eccentrically bored disk weight 46 which may be set in any desired position of angular adjustment by means of a thumb screw 4'7. The clockwise swing of the rock shaft 28 is limited by a thumb screw 48 which is adjustable in an ear 49 projecting from the bearing 27 and which coacts with the arm 33. A jamb nut 50 with a milled edge is utilized as a convenient means for securing the thumb screw 48 against displacement after adjustment.
The operation of my improved tensioning device is as follows:As the diameter of the package C increases incident to its winding, the counterweighted frame 10 of the winding machine is moved clockwise on its fulcrum axis 11 in the known manner. By virtue of its connection to the swinging frame 10, the link 42 is drawn leftward in Figs. I and III. with attendant sliding of its pierced end 41 along the lever 38 toward the fulcrum 39 of the latter. The eifective pressure of the link 42 upon the lever 38 and in turn upon the roller arm 35, is thereby decreased so that the arm 35 will rise from the dot and dash line position to the full line position in Fig. I with attendant anti-clockwise movement of the rock shaft 28. As a consequence, the angle of diversion of the yarn Y between the pig-tail guides 18, 19 is decreased and the pressure between the disks 21, 22 reduced through easement of the tension of the spring 26. It therefore follows that the restraint upon the yarn Y is gradually lessened from the beginning of the winding operation until the package 0 on the spindle 6 attains its maximum size, or in other words, the drag on the yarn is compensatively varied inversely with the increase in linear speed so that a constant effective tension is maintained to insure uniform winding and distribution of the yarn on the package 0. During winding, the eccentric weighted disk 46 acts to stabilize the device against spasmodic operation. By virtue of provision of the various adjustments hereinbefore described, the device may obviously be set for winding yarns of different gages or weights or for predetermining any desired degree of tension.
It is to be understood that I do not consider myself limited to the precise details of construction herein illustrated and described since these are capable of modification within the scope of the appended claims.
