Abstract: 23,843. Wardwell, S. W. Dec. 31. Winding-machines.-Relates to a machine for winding slightly-conical cops or masses of yarn, each made up of a number of sections which are wound successively on the same spindle or core, the yarn bemg laid in a series of spirals which cross one another in the manner known as the " V or " Universal wind." The machine comprises the spindle 9 and guide i, carried by a traverse bar sliding on a pivoted frame F, which is weighted to cause the guide to bear on the cop as it is wound, but swings outwards as the cop increases in size, the guide being prevented from moving towards the cop, when it has been once moved outwards by a suitable detent arrangement. When each section but the last is completely wound, the traverse bar is extended, so as to move the guide i into the position suitable for winding the next section of the cop ; when the last section has been wound the machine automatically stops. Fig. 19 shows the traverse bar made in two sections 67, 68, connected by a spring catch 69, which is secured to the section 68 operated by the traverse cam, and engages with one or other of a number of slots 66 in the section 67. When the first cop section is completed, the combined rotary and sliding movement of a spring lever H, Fig. 1, one arm 107 of which is blocked by a stud 131 on a lever system connected with the shaft 31, disengages the catch 69 and moves the part 67 of the traverse bar until the guide is beyond the end of the completed cop section ; meanwhile the part 68 of the traverse bar is moved by the traverse cam into its opposite extreme position, and the catch 69 engages with the next notch 66 in the part 67, when the traverse bar is ready for winding the next cop section. The rotary movement of the lever H is effected by the frame F, which swings freely outwards, but is restrained from inward movement by reason of the clamping of a curved plate Q, Fig. 27, pivoted at 73, between a pin 75 and a cam or dog R. The dog R is released by hand to allow the frame F to move towards the spindle, by means of a handle 76, and automatically on the completion of each cop section, by means of a screw 110 on the lever H, which engages with the conical head 79 of a screw on the arm 78 of the cam or dog R. When the machine is stopped, the stud 131 is out of range of the arm 107, so that the movement outwards of the lever H, while piecing up, does not affect the adjustment of the traverse bar. When the cop has attained a sufficient diameter, the frame F engages with the end of an adjustable screw 7 on the lever E, whereby the catches 43, 46 become disengaged and the machine is stopped automatically. The stoppage is, however, only effected on the completion of the last cop section. The frame F is fitted with a sliding bar 80, Fig. 19, having an aperture near its end, which, when all the cop sections except the last are being wound, is opposite the screw 7. During the first movement of the traverse bar for the formation of the last cop section, a projection 67<a> on the guide-holder 181 engages with a lever 81 on the bar 80, and moves the latter until a solid portion of the bar is brought opposite the screw 7, so that the machine may be stopped after the last cop section has been wound. For resetting the part 67 in its starting position, the catch 69 is released by pressing backwards the bar 80 by means of the spring lever 81<b>, until a spring blade 83 on the back of the bar 80 is forced against the latch 69, by reason of a bevelled catch 84 on the blade engaging with a bevelled aperture 85 in the bar F. The thread passes to the spindle through a tension apparatus c consisting of two sets of interlocking fingers, one of which is weighted, and over a stud 56 on a tumbler lever 51. Should the thread break or become too slack, the upper end of the lever 51 engages with a collar on the spindle, and the catches 43 and 46 are disengaged to stop the machine, while the pivoted section of the tension apparatus is operated by the lower end of the lever 51, so as to release the tension on the yarn. The cam shaft K is driven from the spindle shaft through suitable "gainer mechanism," including an expansion pulley, which permits the relation between the reciprocation of the thread-guide and the rotation of the spindle to be changed. When the machine is small, several spindles may be mounted on a common frame in the manner shown in Fig. 5, and operated by common driving-mechanism. Both the spindle and cam shafts are driven through clutch mechanism and, in order to ensure that both shafts shall be stopped or started simultaneously, the clutches are simultaneously operated, and the shafts braked &c. by the levers T, T', Fig. 9, of which the extremities t, t' engage with cam discs on the sliding parts of the clutches, the levers being simultaneously operated by the lever 33 from the shaft 31.
