Abstract: 12,109. Levy, H. July 2, 1904, [date applied for under Patents Act, 1901]. Winding or spooling machines.-Relates to a machine for automatically winding thread spools inside shuttles for embroidery machines. The hollow winding- spindle, 5, Fig. 7, first grips the thread by withdrawing it into the bore of the spindle by means of a h ok 6, and then is inserted through a hole 3, Fig. 14, in the rear of the shuttle. During the winding of the spool, the thread is guided along a slot in the shuttle wall by a guide 7, actuated by an eccentric and rod 81. When the winding is completed, a hook 11 engages the thread at the end of the spindle and draws a loop up into the tube 10. The thread loop is then taken by the tube under the spring 17 and into the path of a hook 13, which, seizing it at the same time that the hook 6 releases the end of it, drags the end through the hole 15. A feeler 8 rests upon the spool and acts automatically to stop the spindle when the spool is full. The shuttles are carried in a magazine 1, Fig. 1, which is moved axially by a crank and rod 46, 47 in order that the spool spindle 5 may be inserted and withdrawn. It is rotated step by step, as the shuttles are filled, by a crownwheel 43, a projection 45 on which engages with a wheel 49. The crownwheel is rotated by a wheel 42 when the clutch 30 is in gear. When a shuttle is in position to be filled, the shaft 19, carrying the spool spindle, is rotated by friction cones 21, 22. A clutch 29, through which a shaft 27 is driven, is held open by the feeler 8, the tail of which is behind a collar 61 on the shaft. When the spool is completed, the feeler 8 releases the shaft 27, which is moved to the right by a spring 31, thereby closing the clutch 29 and, through a lever 63 and a rod 64, with - drawing the cone 21 out of gear to stop the spool spindle. Cams 33, 34 then rotate and actuate levers 37, 38 universally mounted on a lever arm 39, to lower the tube 10 and engage the thread as described. A cam 41 actuates the pivot lever 39 to draw the thread-tube 10 across the shuttle. The tube is guided in its movement by slots in a plate 83 and in the frame. A pin 59 on the cam disk 33 then engages a lever 58 and actuates the hook 13 to complete the threading process. When this is done, the parts are returned to their initial positions and a cam 70 releases a sleeve 69 and allows the closing of a clutch 30, in order to'allow the moving of the magazine. Un the out stroke of the rod 47, a projection 52 rotates a lever 53 and thereby the lever 55, which actuates the hook 6, Fig. 7, to engage the thread in readiness for the next shuttle. On the return stroke, the projection 52 rotates the lever 53 in the opposite direction and raises an arm, carrying shears 56, which are closed by a fixed stop and so sever the thread between the hook 6 and the shuttle last filled. When all the shuttles are filled, a projection 71 on the wheel 49 engages a spring hook 72 and releases a drop weight lever 74. In :falling, this rotates a lever 79 which engages a stop 80 and so disconnects the shaft 19. The connecting-rod 77 also disconnects the clutches 29, 30.
