Abstract: 323,416. Fraser, G., Fraser, N., and Fraser, J. Feb. 28, 1929. Sliver-balling apparatus.-A machine for balling slivers comprises a pair of coaxial discs 1, Figs. 1 and 2, carrying integral arbor sections 2, mounted on ball bearings 3 on pins 4 carried by arms 5 pivoted at 6 to. a sleeve 7 loose on a shaft 8. The sliver 26 is wound on the sections 2 by a fluted drum 10. At the beginning of the ball the discs 1 rest on and are driven by friction rollers 23, until sufficient sliver has been wound to come into contact with the drum 10 and lift the discs 1 from the rollers 23. The machine is driven by a chain on a shaft carrying a sprocket 17, which drives the rollers 23, and a gear 16 which drives the drum 10. The sleeve 8 carries by an arm 47, Fig. 5, a depending arm 45 which is normally held by a spring 58 against a pin 61 carried by a pivoted arm 51. When the ball of sliver has attained a predetermined size the arms 5 have been raised sufficiently to lift the arm 45 high enough to bring a notch 62 opposite the pin 61, whereupon to spring 58 moves the arm 45 to the left. A cam 53 on the shaft 11 of the drum 10 then raises the arm 51 slightly to support the ball and take the load off the drum 10. A cam 50 on the shaft 11 then raises a rod 43 and operates an arm 42 to swing the arms 5 apart and withdraw the sections 2 from the ball. The sleeve 7 has mounted on it an arm 28 carrying discs 27 which are rotated by connecting links 37, 39 from the arm 42. Between the discs 27, Fig. 6, are mounted a pair of opposed curved links 30 connected to the arms 5 by pivots 31, 33. A roller 27<1> and spring 27<2> hold the discs in the " open " and " closed " positions. The ball, thus released, falls on to the drum 10 and is ejected on to a pair of rollers or other stand from which it can be removed. After a slight dwell to allow for the ejection of the ball a cam 56 on the shaft 11 engages a projection 54 on the arm 45 and pushes it to the right, whereupon the arm 45, and arms 5 descend to replace the discs 1 for the winding of a new ball. As the arms descend the arm 39 is moved to replace the sections 2 and nip the sliver between them whereby the sliver is severed and winding is recommenced. The sleeve 7 also carries an arm 63 from which depends a link 65 connected at its lower end through a bell crank lever 73, 70, Fig. 7, to the piston 66 of a dash pot arrangement, comprising end chambers. 66', 66<2>, and a fluid chamber 86. During the rise of the arms 5 the piston is moved to compress the fluid in the chamber 66<2>, the valve 81 being held closed and only slight leakage of fluid into the chamber 86 being allowed. This supplies the necessary pressure between the ball being wound and the drum 10. After the wound ball has been ejected and as the arms 5 descend the piston 66 moves to the left and compresses the fluid in the chamber 66<1>, thus cushioning the descent of the parts. The valve 74 is held closed by a lever 77 controlled by a spring 78 and adjustment is secured by a screw 79 and stop 80. The valve 74 is opened by link 88 and spring 92 connected to an arm on the shaft 41. To allow the ejection of a partially wound ball an arm 112 is raised to release a catch 115 and free an arm 116 centred on the shaft 41. The arm 112 is connected to a latch 123, Fig. 10, which when raised allows an arm 120 centred on the shaft 41 to drop into engagement with an arm 118. The arm 112 is also connected by a link 108 to means to open the valve 81 of the dash pot arrangement. The arm 116 when pressed forward carries a projection 117 into engagement with the arm 39 and operates the discs 27 to withdraw the sections 2 from the ball. This movement also closes the valve 74. Reverse movement of the lever 116 brings the set screw 119 in the arm 120 into engagement with the arm 39 and restores the sections 2. and also reopens the valve 74. The valves 74, 81 may be pedal controlled. The machine may be adapted to operate, on the winding of a predetermined length of sliver.
