631,476. Cop-winding machines. MASCHINENFABRIK SCHWEITER AKT.- GES. Feb. 28, 1947, No. 5821. Convention date, March 11, 1946. [Class 120 (iii)] This invention relates to means for automatically feeding fresh winding bobbins to automatic winding machines with automatic bobbin change in which the empty bobbins &c. are fed to the machine by an endless conveyer arrangement and is characterized in that the empty bobbins, delivered by continuously moving chains 74, 75, each cop being housed in a vertical cup 69 with a movable cover 77, are released therefrom by a pawl 52 which contacts and swings the cup-covers 77 and allows cops to fall into a hopper 14 down which they slide to a spring-urged feeding cup 20 close to the winding position. The cup 20 is provided on an oscillatable lever 21, actuated from a cam shaft 25, which moves the empty cop, after a full one has been doffed, to a position between a driving head 5 and a holding cup 11. In its passage down the hopper 14, each cop depresses a counterpoised flap 62 to lift a hooked rod 44 to release a plate 50 which pivots forwardly and moves the pawl 52 from the path of the cups 69 to ensure no further delivery of empty cops until the plate 50 and pawl 52 are reset by the rotation of shaft 25 operating through the bell crank 42 and the hooked rod 44 to bring the pawl 52 into the paths of travel of the cups 69. Specifications 534,769 and 536,010 are referred to.
