My invention relates to knitting full-fashioned ‘
hosiery, and relates particularly to the topping
mechanism to be utilized upon a “single-unit”
machine for knitting‘ full-‘fashioned hosiery.
Two‘ machines have been used for knitting a
complete“ full-fashioned stocking. However, in

‘Referring to the drawings, in Figs. 1, 2 and 6 is
support 28 together.
Mounted upon the upper surface of the central
bar A adjacent one end thereof is a bracket,
generally designated as 32. A second bracket 31%,
similar in detail of. construction to the bracket 32,
is mounted upon the other end of the central
bar ‘A. The bracket 32 has a. plurality of corru
gations on its lower flange surface which are
adapted to interlock with their complemental
corrugations on the top of the central bar lil.
Centrally extending through the flange portion
of the bracket is a longitudinally extending slot
through which a holding bolt 36 passes into a
threaded bolt hole in the central bar It]. The
bolt 3t‘ holds the bracket securely to the bar H].
The bracket 32 is adapted to be adjustably‘
mounted on the bar support, by virtue of the slot
in the wing, the adjustment is essential in order
to provide a means for knitting stockings of dif
ferent sizes.
A body portion 38 of the bracket 32 has an
annular bearing 49 whose bearing surface is ver
shown a topping mechanism comprising a cen
tral topping bar, generally designated as A, and ‘ tically extending.
a‘ plurality of side bars or side wings, generally
designated as B, BI. One side bar is pivotally
mounted adjacent each end of the central top
ping bar A, hence two sidebars B, Bl essentially
are employed. The central bar A is comprised
of an elongated bar 10 of wood, metal, or com
posite material, such as a phenolic condensation
product, having a‘ relatively thin downwardly ex
‘ tending tongue [2 wherein one side wall I4 is sub
stantially parallel to the vertically extending
The bearing ?ll extends away
from one side of. the body portion 38 of the
bracket in order that the side bar may oscillate
freely by not engaging the body portion, as here
inafter shall be further described.
A vertically extending journal or pintle Al is
mounted on the top of the side bar 13, adjacent
the vertical side which is closest to the central
topping bar A. The journal bearing provides the
pivot about which the side bar oscillates after it
is inserted in the bearing 4|] of the bracket 32.
The side bar B is comprised of a rectangular
block of wood, metal, or composite material made
up of two sections 42 and 44. In Fig. 3 I show
the sections 42 and 44 dovetailed together.
A plurality of vertically extending grooves 46
are in the section 42, and a plurality of grooves
48, complemental to the grooves 46, are in the
section 44.
The grooves 48 in side wing section 44 are not
10 continuous as they are broken by a large rec
tangular slot. Horizontally extending parallel
walls 52 and 54, see Figs. 1 and 2, de?ne the top
and bottom, respectively, of the rectangular
opening 59 in the side wing section 44.
Securely mounted between the bottom ledge 54
and the bottom of the section 44 is an expansion
spring 58. The spring 55 is curved in the shape
of a spoon 58 at its long extended end, with the
curved side 58 expanding inwardly towards the
20" longitudinal center of the groove. '
Each of the vertically extending grooves, de
fined by the grooves 46, 48 in each of the side
bars, provides the guides for each slidable trans
fer point or needle, generally designated as 69.
25 The longitudinal distance between the center of
adjacent grooves, each of which house a trans
ferring or lifting needle, is equal to the distance
between adjacent knitting needles on the needle
Each transfer needle 60’ has a pointed end 62
which is adapted to pierce through a loop in a
stocking blank. The hexagonal needle 60 has
parallel side walls 66 and 68 and end faces 10, 12
converging from one edge of each side wall, thus,
35 the shanks are adapted to readily slide within
the grooves when a side extension 14 attached
to the shank, near the top edge, is moved.
‘Suitable retaining means, such as screws’ or
bolts 16, in addition to the dovetailed joints, aid
in holding the sections of the side bar B together.
The central bar A is mounted upon the elon
gated rectangular supporting rod 28 by means
of the holding bolts 30. The rectangular bar 28
carries two shift bars 18 and 89 on its upper sur
face. Each of the shift bars 18, 89 are connected
to each of the side bars by means of two pivoted
links 82, 84, and 86, 88, respectively. The link
82 is pivoted at one end 82A to the push bar 18.
The other end of the link 82 is pivoted at 823 to
a bracket or link 84, the latter is attached to the
side bar B. Each of the links 82 and 84 have
one of their ends pivotally joined together, and
the other end of the link 84 is securely attached
to the movable side wing B, and the other free
end of the link 82 is pivotally attached, as at 82A,
to the shift bar 18. The linkage arrangement 82,
84 between the oscillatory side wing'B and the
translatory movable push bar 18 results in force
being applied to the rotary side bar B when the
60 push bar 18 is moved in a rectilinear direction.
'Thus, movement of the shift bar 18 in a trans
latory direction to the left causes an oscillatory
movement of the side bar B in a clockwise direc
tion. Movement of the shift bar‘ 99 to the right
moves the side topping bar Bl counterclockwise.
The link 86 is pivoted at 86A, 86B. The shift
bars 18 and 88 are connected to an operating
mechanism whereby the shift bars are moved in
opposite directions when the single operating
mechanism is actuated. The purpose of the shift
bar is to move the side bar from the same plane
as the plane of the middle bar A to a plane per
' pendicular to the plane of the middle bar, or vice
A plurality of L-shaped brackets 90 hold the
shift bars in position on the rectangular bar 26.
Since the topping mechanism must move in a
horizontal plane as well as in a vertical plane,
suitable mechanism, as described in my prior
Patent No. 1,920,005, is employed. Such mech
anism causes the rod 92 to ascend or descend, and
moves the rod 92 forward and backward in a
rectilinear direction.
The supporting bar 28 is mounted on a grooved 10
bracket support 94 which is attached to the hori
zontally and vertically movable bar 92.
Each transfer needle 24, for use in the central
or front topping bar A, may have a pointed,
slightly curved lifting point or a straight point.
Extending from the needle body is a bend 95, an
offset 96 from the bend, and an inturned end 98
which enables the needle to rest securely within
the grooves of the front bar.
In my Patent No. 1,912,005, I have shown a 20
loop designated as X which has no needle there
through. The purpose of omitting the needle
from the loop X is to insure coincidence of the
loop Y with the loop X when the heel portions are
placed in the positions shown in Patent No. 25
1,912,005. These two loops are placed on the
same needle so that the heel at such point will
be strengthened. If a needle were placed in
loop X when the heel is knitted, a hole would
result after the foot of the stocking is completed. .
Thereforc, it is to be remembered that the end
transfer needle in. the central topping bar and
the adjoining needle in the side topping bar must
be spaced so that two loops will be placed upon
one needle, this space is twice the distance of the
space which is between adjoining needles.
It is to be remembered that the side topping
bar BI and its supporting bracket 34 is comple
mentary in arrangement and construction with
respect to the side topping bar B and its support 40
ing bracket 32, except that one is for the right
hand side and the other is for the left hand
side. The complete topping bar unit is adapted
to be placed over the knitting needles of the flat
knitting machine.
Although this invention has been described in
considerable detail, such description is intended
as illustrative rather than limiting, as the in
vention may be variously embodied. My in
vention, therefore, is not to be restricted except
as far as it is made necessary by the prior art
and by the spirit of the appended claims.
I claim as my invention:
1. A topping bar comprising a bar and a plu
rality of slidable needles therein, grooves in said
bar to guide the needles, a spring engaging each
of the slidable needles, and means on each of
said needles for limiting its movement.
2. A topping bar comprising a plurality of side
bars and a front bar, each of said side bars having 60
a plurality of grooves, a topping needle inserted
in each of said grooves, means on. each needle to
limit the movement of the needle, a plurality of
needles ?xed in position in said front bar, and
curved points on the ?xed needles.
3. A side topping bar comprising two sections
rigidly secured together, a plurality of slots in
each section, the slots in one section being com
plementary to the slots in the second section
whereby grooves are de?ned for slidable needles,
and a resilient expanding spring extending into
each groove.
