Abstract: 25,158. Wardwell, S. W. Dec. 10. Winding-machines.-The material is passed through an adjustable tension device T, over a bar 56 on a detector or stop lever 51, and over a rail 5 to the traversing thread-guide i, by which it is wound into conical or cylindrical packages on the spindle, the tube or shell on which the thread is wound being secured on the spindle by any suitable means, such as those described in Specification No. 25,159, A.D. 1901. The tension device consists of two sets of bars or fingers, of which one set c, Fig. 20, is fixed and in the form of a grid, through the openings in which the pivoted fingers d of the other set may pass from the position shown in dotted lines to that shown in full lines. The fixed grid is provided with a frame or guide c<1> for conducting the thread to its proper place across the grid, and the pivoted fingers are fitted with an arm d<2>, which may be engaged by the stop rod 51 for releasing the tension on the thread, and they are also connected by a link 87 with a weighting-apparatus for applying the tension. On the oscillating frame F carrying the traversing- guide &c. is a stud M' connected by an arm 86 with the link 87 of the tension device, the arm &c. being balanced by means of a counterweight. The stud also carries a number of flat weights m, which can be moved from one side to the other of the axis of the stud, for the purpose of adjusting the tension ; also the oscillation of the lever F due to the increasing size of the package serves to alter the inclination of the weights and so to diminish the tension automatically as the winding takes place. A suitable detent may be employed for preventing the lever F from moving inwards when it has been moved outwards by the ball of thread. The traverse bar 69 is adjustably screwed into the slide 68, which is operated by the cam D and formed with flanges for engaging in grooves of the guide-frame 80, 81, the screw connection being such as to allow the guide to move towards and from the cop, when this is of a conical shape, independently of the movement of the frame 80. The outer end 81 of the guide-frame is provided with interchangeable guide-plates, against which the stem of the thread-guide bears during its traverse. The guide may be formed of glass, porcelain, &c., and inserted in a suitable stem, or the stem and guide may be formed from one piece of metal, which is inserted in a slide or holder 67 secured to the end of the traverse bar. The driving-pulley 12 is loose on the spindle shaft, to which it is connected by a clutch, the spindle shaft being connected with the cam shaft 25 by means of the expansible pulley P and the toothed gearing shown, part of which is carried by a loose cover plate g, which is weighted by means of a cord and weight 41 for the purpose of applying a suitable tension to the band. Both the spindle shaft and the cam shaft may be hollow and contain lubricant, which passes to the bearings through suitable apertures. The machine is stopped and started by the rotation of a spring rod 21 operated by a handle or lever E'. The handle E' is held in the operative position by a catch 43 on the spring lever E. the lever E and the curved arm 45 of the lever E<1> being connected with one another so as to strengthen the lever E &c., by means of a stud. and-slot arrangement e, 45<a>. The rod 51 is pivoted on the lever E, and is weighted at its upper end, but is normally maintained by the tension of the thread passing over the projection 56, with the weighted end out of contact with a cam or collar 53 on the spindle. When a thread breaks or fails. the weighted upper end of the lever 51 falls against the cam 53, the catch 43 is disengaged, the shaft 21 is rotated by its spring so as to stop the machine, and the arm 45 of the handle or lever E<1>, by means of a stud 0, operates the lever 51 so as to cause the lower end thereof to oscillate the pivoted portion d of the tension device and release the tension on the yarn.
