Application February 16, 1938, Serial No. 190,763

s claims. (o1.~ ca_-191)
This invention relates to knitted fabrics, and
more particularly to a knitted pile fabric where
in the threads or yarns constituting the same are
so arranged that the _fabric is substantially run
5 resisting and is provided, in addition to the
regular plain stitch, with loops extending out
wardly lfrom one surface forming a loop-pile
which may be conveniently napped to give> the
fabric a woolly appearance.
v
_
One object of >this invention is to provide a
fabric of the above nature wherein all of the
pile loops are substantially the same in length
and are firmly retained in the fabric.
'
Another object is' to provide a knitted pile
15 fabric of the above nature having a _new se
quence of stitches including floats in'combina
tion with pile-loops.
'
'
A further object is to provide a knitted pile
fabric of the above nature having a ribbed sur
face formed by the pile loops and 4which, after
napping, possesses a ribbed woolly appearance.
A still further object is to provide an im
proved _knitted pile fabric of the above nature
which will be simple and easy to manufacture,
25
flexible and elastic, non-crushable, substantially
' run-resisting, and very efficient and durable in
use.
.
’
With these and other objects in view, there has
been illustrated on the accompanying draw
30 ings one form in which the invention may be
conveniently embodied in practice.
In the drawings:

Fig. 11 is a detail View, similar to Fig. 10, show 5
ing the sinker as it appears when engaging two
yarns-_one for producing a knitting stitch, and
the other 'for forming a pile-loop.
'
One important Vadvantage obtained by the novel
arrangement of the threads o_r yarns in the im
proved knitted pile fabric herein disclosed is that
said fabric may be made on an ordinary plain
knitting machine without employing compli
cated mechanisms or special attachments,--1t
merely being necessary to use a new form of 15
. sinker and a. 'suitable controlling cam therefor
together with a needle-actuating cam cylinder
arranged to produce ñoats at'certain desired
points.
Referring now to the drawings, wherein like
reference numerals denote corresponding parts
throughout the several views, the numeral l0
indicates a circular stationary base or table upon
which a plurality of upstanding brackets il are
mounted.
The brackets li support a stationary '
ring member l2, which carries a plurality of
horizontal arcuate plates i3 forming a segmental
l substantially circular sinker-operating cam mem
Provision is. also made ofv a rotating needle
carrying cylinder id and a. 'stationary annular
needle-actuating cam cylinder l5, the latter be

ing rigidly secured tothe stationary table lll in
the usual manner and located below said sta
tionary ring member l2. The rotary needle cyl 35
inder i4 carries a plurality of needles it and Il
which are adapted to be engaged by the station
ary needle cam cylinder I5 to cause said needles
to travel upwardly and downwardly during the
operation of the machine. The needles I6 are 40
of the type having long butts, while the needles

provided at its upper end with the usual spring

the knitting action. Operating between the suc
cessive needles I 6 and Il are a series of horizon
