What is claimed is:
1. ‘A loop transfer element‘ adapted for use
with aknitting needle comprising a shank and 20
eled to form a V-shaped ridge‘EB. The hook _ a bifurcated hook having two parallel hook
, portion of the implement is formed by bending a ‘shaped cheek members extending reversely of
_ portion of this bar stock over into a position par
allel to the shank. A vertically extending slot 66
25 is then out along the entire length of the outer
portion of the hook to form the two cheek por
tions 62 and 64 of the implement. The depth of
the slot 6|] is gauged to leave a thin connecting
wall 86 connecting the cheek members ‘62 and 64
30 along their inner edge. Finally, one of the cheek
portions 64 and a' portion of thewall 66 is cut‘
away at an angle to form‘ a cammed surface 68
which can operate to engage a kink of yarn caught
on the tip of the cheek 62 and to spread this loop
over. the lower portion of the cheek 64 as the hook
is moved upwardly from the dotted line to the
full line position illustrated for the hook 30 in
Fig. 8. Applicant's hook element 56 formed in
this manner is similar to the hook 30 previously
40 described in having a V-shaped bottom surface
to facilitate the downward movement of the hook
between the sinkers and knockover elements, a
V-shaped rear side to facilitate the positioning
of the advancing sinkers between the hook ele
ments in the position illustrated generally in Fig.
the shank arranged’for a position of the shank
portion substantially parallel to and at the
vfront 'side of the needle shank to extend to either 25
side of the needle, said cheeks having inwardly
bent tips arranged to extend beyond and to the
backs of the needle shanks to engage with and
receive a needle wale loop ‘from the needle shank,
and relatively protruding outer edges adapted to
engage with and guide the needle shank laterally
. between the cheeks.

a bifurcated hook having two parallel’hook
shaped cheek members extending reversely of
the shank arranged for a position of the shank
portion substantially parallel to and at the front
side of the needle shank to extend to either side -
of the needle, said cheeks having tips converg 40

back of the needle shank to engage and receive
a needle wale loop from the needle shank.
3.,A loop transfer elementadapted for use

21 and 22, Fig. 21 showing the position of the
hook 56 which corresponds to that illustrated for
book 30 in Figs. 7 and 16, and Fig. 22 showing the
hook 56 in a position which corresponds to the
position of the hook 30 shown in Figs. 8 and 17.
As will be evident from these ?gures, the books
56 are moved forwardly so that the shank of the
needle isiburied in the recess orv slot 60, and the
tip portion of the cheek 62 is in a position during
subsequent upward movement of the hook to en
65 gage the bar of yarn extending to the adjacent
needle prior to the advance of the dividers. As
vthe upward movement of the hook‘ is continued,
‘the yarn kink on‘ the needle shank is engaged by
the angled surface 68 causing the loop to be
spread over the abbreviated cheek 64, as shown in
Fig. 22, so that the yarn kink held on the book

tively protruding outer edges adapted to engage
