This invention relates to knitting machines and
more especially to the web holding mechanism
of such machines.

‘ A web holder ring 20 ?ts tightly into the upper
end of the needle cylinder l0 and has an ex
teriorly turned ?ange 20’ to rest upon the top
ingly holding them in position for free recipro- ' edge of the needle cylinder. This ring 20 also

'
Heretofore, it has been customary to lubricate
the web holders and needles merely by pouring
15
oil on to the Web-holder ring which is very ob
jectionable due to the fact that there is nothing
to prevent the oil from running off with theresult
v20 that the web holders and needles run dry and
become hot, causing excessive wear and the
formation of a black substance which, when the
mechanism is again oiled, is wiped oif'on the
fabric. The present invention obviates the con
25 ditions above described and, according to the
invention, the web-holder ring is provided with
an annular groove in which is arranged a felt
wick which is engaged by the inner ends of the
web holders. The felt wick is saturated with oil
30 and reciprocation of the holders causes applica
tion of lubricant to the sides as well as the bot
tom of the holders with transfer of some of the
lubricant to the needles.
The thorough lubrica
tion of the holders and needles prevents them
00 Q1 from becoming hot and minimizes the wear.
Other objects, novel features and advantages
will become apparent from the'following speci?
cation and accompanying drawing, wherein:

Fig. 4 is a fragmentary perspective view of the

'
The needle cylinder I0 is provided with ex
terior grooves II in which are arranged needles
I2. A web holder bed I3 is tightly ?tted on a
5 O flange |4 formed on the needle cylinder l0. As
is usual in the art, the bed I3 is radially grooved
at |5, the last-named grooves being spaced be
55
tween the needle grooves “. On the bed In is
rotatablymounted a- web-holder cam ring l6
having a ?ange H for engagement with the
part of the top of the'ring 20. The body of the
?ange 2| has an upstanding portion 2|’ which
is substantially triangular inv cross section, the _
hypotenuse of the triangle extending down
wardly and inwardly, whereby a downwardly and
inwardly inclined surface is provided. The part
2|’ is provided with a plurality of radial slots
24 to receive the web-holders and thebody por
tion of ?ange 2| is provided with the slots 24" for
the needles 25'.
As is well understood, ring 20 supports a plu
rality of web holders 25 for movement radially
of said ring, and guides them during their move
20
ment in and out. These web holders are each
provided with an upper arm 26 which passes
through the slots 24 and rests upon the upper
bearing surface 23, and a lower arm 21 which
moves under the ?ange 2| with its upper surface
engaging the under bearing surface 22. ‘This 30
arrangement of arms and bearing surfaces and
slots insures proper movement of the web holders
during operation.
I provide an annular groove 28 in the upper
surface of ring 20 and providea wick 29 of felt 35
or other suitable material in said groove. It is
to be noted that the wick 29 is located near the
inner ends of the radial slots 24 in the web hold
ing ring 20 and near the bottom of the inclined
surface 30 of the slotted portion of said ring.
Any suitable lubricant is used to saturate the
wick 29. The arm 26 of the web holder 25 en
gages the wick 29 and as it reciprocates across
the wick, it is lubricated. Some of the lubricant
is carried by the web holders through the grooves iii 5
24 and supplied to the needles. Thus both the web holders and needles are thoroughly lubri
cated thereby preventing them from becoming
hot and minimizing wear. Also, the wick 29
serves to yieldingly hold the arm 26 in position
tending to prevent canting of the web holder by
pull exerted from the needles I2. The wick,
therefore, not only serves to effect lubrication of
the web holders and needles, but also minimizes
2
2,120,796
the possibility of binding of the arms 26 and 21
. against the surfaces of the ?ange 2|.
The above-described arrangement provides 1 a
highly e?lcient and inexpensive device- for ef
fecting thorough and uniform lubrication of the
web- holders and needles. The wick-retains suf.?cient lubricant for a long period of operation
and reduces waste of lubricant to a minimum.
