Abstract: 8210. Alexander & Co., R. F. & J., and Mackie, J. April 22. Balling twine.-The flyer is driven in the ordinary manner until the greater part of the ball is wound, when it is stopped and the ticketing-mechanism places a ticket on the ball ; the flyer then laces in the ticket and completes the ball, when it again stops in a position clear of the ending-mechanism. When the end of the thread has been secured in the ball, the flyer is moved forwards so as to place the thread into a clamping-hook, which holds it until it is cut ready for starting the next ball. The Provisional Specification refers to the Specification No. 21,174, A.D. 1899. The thread is held during the cutting operation and for the starting of the ball by a hook 1, Fig. 5, on the end of a spring rod 2 operated by a cam, the thread being held between the hook and the end of a tube 3 enclosing the rod 2, while a curved part 4 of the hook draws the thread into a loop, which is cut by a spring knife in the form of a tube surrounding the tube 3. The cam shaft is driven by spur and chain gearing from the loose pulley 17, Fig. 4, on the flyer shaft 14. The pulley 17 also operates the ticketing, ending, and doffing mechanism, and also the mechanism for shifting the driving-belt between the pulley 17 and the fast pulley on the shaft 14. During the winding of the body of the ball, the strap 15 is held on the fast pulley 19 by a catch 21, which engages with the spring strap-fork rod 18. The catch 21 is disengaged at the proper time by a tripping-mechanism, in which catches on a rotary disc operate a lever and weighted rod connected with the catch 21. The flyer shaft 14 is driven from the pulley 17 by means of a cam and ratchet mechanism, the pawl of which is automatically disengaged by a sliding and adjustable guard 36 so as to stop the flyer in a position clear of the ticketing-mechanism, the guard 36 being operated from the strap-fork bar 18 through the levers 38, 39, 41. The guard is moved into a position clear of the ratchet mechanism during the winding of the body of the ball, when the flyer shaft is driven by a belt from the countersbaft. On the cam shaft 8, Fig. 20, to which the pulley 17 is geared, is mounted a disc 43 carrying a pawl v, which operates a toothed quadrant 44 geared with the hollow rocking shaft 46 of the ticketing-mechanism. When the quadrant has moved through certain angle, the pawl v is disengaged by the set-screw w, and the quadrant is returned to its starting position by a spring in the cylinder y. The catch 21 of the bar 18 is carried by the spring lever 22, the spring 50 of which is stronger than the spring 20, when the ticketing operation is completed, the lever 22 is moved back by a cam 49 and its catch 21 again engages with the rod 18 and moves the strap on the fast pulley, which again starts the flyers for completing the ball. When the ball is completed, the catch 21 is again released in the manner above described, and the pulley 17 is again rotated for operating the ending and doffing mechanism. The systems of levers for operating the doffing and ending mechanism are shown in Fig. 5, four cams on the cam shaft being connected respectively with the rocking shaft 53 for actuating the doffing-tube 73, with the shaft 57 for operating the thread-cutting knife, with the shaft 61 connected with the ending-needle 64, and with the shaft 70 which operates the combined thread hook and clamp. During the ending of the ball, the flyer is moved forwards to lay the thread across the front of the ending needle 64. The tickets are placed on the perforated extremities of hollow arms connected with the hollow shaft 46, Figs. 17 and 18, which is connected with a suction apparatus when the arms are in the withdrawn position, but, when the tickets are applied to the balls, the connection with the suction apparatus is automatically closed, while a connection with the atmosphere is made. The shaft 46, an, adjustable bearing s, and a fixed carrying-sleeve x are each provided with a port 75, 76, and at the end connected with the suction apparatus, the bearing s and the shaft 46 are each half-closed by diaphragms u, t so arranged that on the rocking of the shaft 46, the connection at the end with the suction apparatus is open when the ports 75,76 are closed, and vice versÔ. The valve of the suction apparatus is operated from the strap-fork rod 18. Brake mechanism is provided for flowing down the motion of the several parts when required. The spindle frame is oscillated by lever mechanism from the shaft 25, and catch mechanism is provi ded for holding the frame in position during the operation of finishing the ball.
