Title: Improvements in or relating to braiding machines
IPC: D04C3/00
Filed: 1922-07-04
Abstract: 182,799. Perron, G. July 5, 1921, [Convention date]. Braiding-machines.- Relates to a machine for producing at high speed dissimilar articles simultaneously. The main frame is dished and provided with stub axles 3 on which work intermeshing gears 5 and associated notched driving-discs 4. The flanges 7, 8 of the discs 4 engage the parts 12, 11 of the bobbin carriers which are kept in place by spring-pressed collars 14 secured by pins 16. The lenticular sliders 12 carry switch plates 13 which by striking stationary plates 21 arranged opposite the crossing-places, permit the bobbins to move in serpentine paths. If a plate 21 is removed or raised and a plate 22 is fixed to an adjacent axle 3 the bobbins will be turned back at this point. The bobbins 28 are mounted horizontally on the carriers and are held in place by leaf springs 25. Each thread passes through an eye 47 in a pivoted arm 36 the lower end 42 of which normally engages notches on the bobbin flange, through an eye 46 in a spring- controlled tension arm 31 and through a fixed eye 45. When the tension on the thread is increased the eyes 46, 47 are brought into line with the eye 45 and the detent arm 42 releases the bobbin and allows the arm 31 to draw off a supply. Should a thread break, the corresponding arm 31 is thrown back against a ring 83 and establishes an electrical circuit which energizes an electromagnet 79. An armature 78 carried by a lever 76 pivoted at 77 thereupon releases the short arm 73<11> of a plate 73 which is pivoted at 72 on the end of a lever 68. The long arm 73<1> then drops into the path of a projection 74 carried by the lower element of a clutch 50, which causes the parts 73, 68 to move from left to right about a pivot 69. This frees a stud 66 on a lever 56, from engagement with a shoulder 67 on the lever 68, and allows a spring 81 to move the lever 56 and disengage the upper element of the clutch 50 carried thereby from the lower element, the machine being thus brought to rest. As the lever 56 moves away from a central spring 82 the circuit is opened. The paths of movement of the bobbin-carriers may be varied bv suitably shaping the plates 13 and by combining various kinds of plates 13 with the stationary plates 21 and 22.
