2, Claims. (Cl. 66-65)
This invention relates to improvements in
knitting machines of the type known as glove
iingering machines. In such a machine, a pre
knitted hand of a knitted glove is inserted in the
machin-e and the fingers knitted thereon. In
the machine under consideration here, each iin
ger is knitted separately, a tube of yarn of suit
able diameter being knitted on the hand at the
proper point and then formed intov a finger by
l C closing the end of the tube.
It is necessary to rethread the machine and
reinsert the glove being processed each time a
finger is to be added; also, the machine often
becomes “snaggedf’ necessitating removal of the
15 carriage from the bed in order to 'unravel the
tangle of yarn. These operations seriously
hamper production, by tying up the machine un
trated being merely one embodiment. The pre
ceding construction is well known in the knit
ting machine ñeld and, therefore, will not be
described further.
As was explained earlier, the machine must be
rethreaded and the glove reinserted each time
a finger is started. To do this successfully, the
carriage has to be operated manually and slowly
for the first few reciprocations. After the iin
ger is started, the machine 4can be mechanically 10
driven until the necessary iinger length has been
knitted. By means about to be explained, I have
provided for both manual and mechanical opera
tion with the operating mechanism for both
types of operation located at the back of the 15
machine away from the carriage with the parts
arranged so that the operator can readily control
til the necessary adjustments or alterations are
made. It is, therefore, the purpose of this in
the machine both during rethreading and knit
vention to provide a glove fingering machine
carriage I is provided by a crank arm Ii] and a
which has been so constructed as to increase, the
availability of the machine for Work by cutting
to a minimum the time consumed in starting
each finger or in removing tangled threads if
25 the yarn becomes snagged.
Referring to Figs. l and 2, reciprocation of the 20
connecting rod II, the latter member being piv
otally connected as at I3 to the carriage I.
Crank arm II is pinned to a shaft I2 which is
supported in bearings on the end of gooseneck 25
extensions I5 of the frame of the machine. A
The particular features which enable meto pulley I1 is pinned to the shaft I2 and connected
accomplish this purpose with my invention willv by belt I8 and a foot-controlled friction clutch
appear more fully by a consideration of the not shown to a suitable rotating shaft. Crank
speciñcation read in conjunction with the draw
arm II also has a handle I9 mounted on one end 30
whereby the carriage I can be reciprocated man

Fig. 1 is a front view of the glove fingering ually if it is so desired. Thus, during the re
threading operation the operator, standing at
Fig. 1; and
move the carriage manually by handle I9, and
then he can provide for continuous operation by
working his foot controlled friction clutch and
by the belt driven pulley taking over the driving
work during the rest of the knitting operation.
Particularly is it to be noted that during the
continuous operation., the rotating parts are at
the back of the machine away from the operator,
which reduces the danger of injury to a mini
mum and provides clear View of the knitting
Fig. 2 is an end elevation of the machine of
Fig. 3 is an enlarged detail of the mounting
for the connecting rod on the carriage.
Referring to Figs. 1 and 2, the knitting ma
chine consists of a reciprocable carriage I slid
ing on ways 2 over a bed 3. The bed 3 carries
needles Il which are reciprocated to perform the
knitting operation by cams carried on the car
riage I. This operation and the construction to
carry it out are well known in the art and will
not, therefore, be further described. The thread
45 5 passes from a suitable tensioning device, not
shown, down through an eye 6 to the bed 3 where
the knitting takes place. The carriage likewise
carries Iguard members 'I and 9 to keep the eyes
of the needles open as they reciprocate from
50 their lowest position, one guard l, located at the
front of the carriage, being a` simple gooseneck
member and the other, 9, being a brush held by
a gooseneck clip. It is not necessarily manda
tory that the guard members 'I and 9 be of dif
ferent construction, the particular form illus
the left of the machine as shown in Fig. 2, can
Often during the knitting operation, the yarn
snarls, and the operator must stop his machine
to untangle the strands. By the construction
described below, the operator can separate the
carriage and bed without disconnecting the driv
ing means, and can very easily gain accessibility
to the needles carried by the bed, with a mini
mum of time wasted.
Referring to Fig. 3, connecting rod I I is thread
ed at the carriage end and passes through a two
piece collar 20 mounted in the pivot I3 which is
suitably journaled in a boss 2|’ built out from
the carriage. The length of the connecting rod
II necessary for proper reciprocation of the car
riage is determined and the rod locked in posi
tion by nuts 2I and 22 which bear on washers
24 and 25. 'I'he two-piece collar Zll‘ is mounted
through the width of the pivot I3, see Fig. 3, so
that with the nuts 2I and 22 in position, the con
necting rod I I can turn around its longitudinal
axis. Thus, the mounting at the carriage end
not only allows the connecting rod to have a wrist
pin motion by means of pivot I3, but also a
twisting motion by reason of two-piece collar 20.
Referring again to Figs. 1 and 2, the Ways 2
consist of rods passing through bosses 26 in the
frame of the machine and are secured in position
by taper pins 21. Thus, as is shown in Fig. 2 by
the dotted position of the parts, if the pins` 21
ec in the front way 2 are removed the rod may be
removed and the carriage rotated to its dotted
position where there is free accessibility to the
bed mechanism. During the swinging of the car
riage on the right way 2 (see Fig. 2), the pivot
, I 3 drops down and twists slightly around the con
necting rod II, but due to the type of connection
between the pivot I3 and the connecting rod II,
there is no difficulty and the connecting rod need
not be disconnected from the carriage. In this
manner the bed of the knitting machine is made
accessible for the operator to untangle yarn and
at the same time the machine need not be dis
assembled or its alignment disturbed.
Having disclosed my invention, what I claim is:
1. In a glove finger knitting machine having a
carriage for reciprocation over a needle-carrying
bed, a pair of ways of circular cross-section for
supporting said carriage, at least one of said ways
being releasably secured to the frame of the ma
chine, in combination with a crank operated con
necting rod for reciprocating said carriage, said
rod being pivoted at a point closely adjacent one
of said ways at one end of the carriage, said pivot
providing for both wrist-pin action and rotational
twist of the connecting rod whereby when the
way remote from the connecting rod pivot is re
moved the carriage may be rotated about the 10
adjacent wai»r at right angles to the plane of
reciprocation without disconnecting the connect
ing rod at the pivot.
2. In a glove ñnger knitting machine, the com
bination of a needle-carrying bed, a carriage
mechanism for reciprocation over the needle-car
rying bed so as to work the needles, a pair of
ways for supporting said carriage mechanism,
means to tip said carriage mechanism up and
back while supported on one of th-e ways, so as
to give access to the needle-carrying bed and the
under part of said mechanism from the front part
of the machine, a power shaft mounted at one
side and back of that way which supports the
carriage mechanism, a hand crank on the end
of said power shaft and in approximately the
vertical plane of said carriage way last men
tioned, a connecting rod between said crank and
the carriage and pivoted on the carriage just
above the last mentioned carriage way, a power 30
driving connection on said shaft in addition to
the hand crank, all constructed and arranged to
give easy access to the whole mechanism Without
interference from the hand and power driving
