Application November 30, 1937, Serial No. 177,209
3 Claims. (C1. 86-110)
This invention relates to knitting machines
with special reference to the verge plates used in
connection with the sinkerhead or loop forming
devices for straight line knitting machines.
5
Among the several objects the more important
are: in reducing strain of the mechanism, pre
venting undue wear; avoiding jack, sinker and
worn plate lines in the fabric; preventing un
even knitting, and effecting very considerable
l0 saving of sinkers, time and material.
More specifically the purpose of the invention
is in the provision of a, verge plate limitedly
movable and resiliently pressed outward away
from the sinker plate.

These objects are accomplished by the n_ovel
construction and arrangement of parts herein
after described and illustrated in the accom
panying drawings, constituting an essential com
l2l)
ponent of this disclosure, and in which:
Figure 1 is a top plan view of the sinker head
(Not shown).
Carried adjustably on the jack bed I6 are a
series of spacer members or jack combs 25 held 5
by a clamp bar 25 and spaced in conformity with
the sinkers I9 whereby alinement is maintained.
A plurality of jacks 2l are pivoted on a rod
23 set in the spacers 25 and pressed forwardly
by individual springs 29, their motion being lim 10
ited by a stop bar 30.
The upper, forwardly curved ends of the jacks
21 are adapted to contact upstanding projections
3| at the rear ends of the sinkers I9.
A plurality of needles 32 are secured in a nee 15
dle bar 33 held by a clamp 34 therein and actu
ated in a manner well known in the art.
'I'he improvements consist in a novel form of
verge plate 35 loosely held on the inclined upper
surface of the cap bar 20 of the sinker head and
floatingly secured against rising by shoulder
tive position.
The verge plate is provided with substantially
triangular openings 31 near its ends, through
which extend pins >3Il ñxed in the cap bar 20.
'I'he rear edge 39 of the plate 35 is downwardly
flanged and positioned in spaced relation to the

Figure 10 is another like view of the same as
further advanced.
Referring in further detail to the drawings,
the machine will be seen to include a frame com
posed of a center bed I5 extending the length
4.3 of the machine; on the rear flanged portion of
the bed is secured a jack bed I6, and on top
of its upright forward portion is a base bar I1,
its lateral edges extending both forwardly and
rearwardly as shown.

rear edge of the cap; in the space thus formed
is inserted a thin flat spring 40, bent sinuously
to produce a series of undulations 4I, and its ends
42 turned angularly, its effect being to normally
press the verge plate 35 rearwardly when it
strikes the sinker projections 3|, cushioning the
contact.
Thus the constant pounding of the sinkers is
minimized, reducing wear and vibration and dis
tributing the shock to the machine.
As changes of construction could be made with
in the scope of the invention, it is intended that
all matter contained in the foregoing descrip
tion or shown in the accompanying drawings
shall be interpreted as illustrative and not in a
limiting sense.
Having thus described the invention, what is
claimed as new and desired to secure by Letters
Patent, isz
