two parts or portions 16 and 18 generally portion 16 is referred to as the mounting portion and portion 18 is referred to as the working component and in the figure disclosed the working component 18 is a sinker which has been soldered into the mounting portion 16 the mounting portion 16 is provided with an aperture 20 that is larger in diameter than the threaded screw or bolt 22 that must pass therethrough a part 24 of the mounting portion 16 circumscribes the free edge 26 forwardly of bolt 22 of the angled mounting bar 12 and may be in contact with the undersurface 28 thereon when element 14 is mounted on bar 12 a small clearance say about 0 1 mm is permissable between under surface 28 and the upper surface of part 24 during the operation of the machine as described below the operating forces will provide a contact between the two surfaces bolt 22 which has a threaded portion thereon is placed through aperture 20 in the mounting portion 16 and threadedly engaged into aperture 32 provided in the generally horizontal portion of the angled mounting bar 12 thus the head 34 on bolt 22 will retain the working element 14 in position on the mounting bar when the bolt is tightened into threaded aperture 32 the working component 18 of element 14 cooperates with knock over sinker 36 which is affixed to another mounting bar 38 latch needle 40 is shown mounted in needle bar 42 which cooperates with the element 14 and the thread guides not shown to generate a ware 44 generally.
