The features of the latch needle

The latch needle has nine main features (Fig. 3.3):

1 The hook, which draws and retains the new loop.

2 The slot or saw cut, which receives the latch-blade (not illustrated).

3 The cheeks or slot walls, which are either punched or riveted to fulcrum the latch-blade (not illustrated).

4 The rivet, which may be plain or threaded. This has been dispensed with on most plate metal needles, by pinching in the slot walls to retain the latch blade.

5 The latch-blade, which locates the latch in the needle.

6 The latch spoon, which is an extension of the blade, and bridges the gap between the hook and the stem covering the hook when closed, as shown in broken lines.

7 The stem, which carries the loop in the clearing or rest position.

8 The butt, which enables the needle to be reciprocated when contacted by cam profiles on either side of it, forming a track. Double-ended purl type needles have a hook at each end; whilst one hook knits, the inactive hook is controlled as a butt by a cam-reciprocated element called a slider.

9 The tail, which is an extension below the butt, giving additional support to the needle and keeping the needle in its trick.
