stud 41 extends inwardly and slides in the bear
ings 32, being surrounded by a compression
spring 50 located between the end wall 28 and
the enlarged part 48. The purpose of the spring
is to hold the hook normally in the position
shown in Fig. 1 with the lower vertical part 5|
of the hook extending along the corresponding
adjacent part of the ear 35. The hook may be
offset as indicated in Fig. 1 but preferably does
not pass through any part of the ear.
The stud 47, being cylindrical, would be free
to turn in its bearings 3i and32, and in order
to prevent this I secure a guide pin 55 to the
hook at a point below. the end 46. The guide
pin passes through a hole‘ 56 in the ear and 'is
spaced sufficiently belowthe chain to permit the
customary upward motion of the tube frame
30 necessary to ‘permit the hook end 46 to slide over
the highest part of the chain link I2. When the
tube frame is in an inverted position shoulders
60 of the car may be relied upon’ to engage the
single links 6|‘ of the chain to support the tube
frame, ‘but if desired, the pin 55 may engage
the chain links. I l and ' l2 for this purpose.
do not wish to be limited to this latter feature.
~The clutch I3 has extending inwardly there

40 thereof-provided with a-lip ‘H curved down
wardly and inwardly as at'l2 in the usual man
Side plates 13_ of the clutch require the
tube frame to rock with the clutch.
In operation, the parts are normally in the po
45 sition shown in Fig. 1 with the hook_over the
link l2 and the clutch spaced from the tube
found in similar constructions, being perforated
only at 31 and 56. The hook may be wider than 20
those heretofore used due to the fact that it
is not required to pass through a slot in the ear
and the hook is provided with a comparatively
cheap but effective slide bearing.‘ The guide pin
55serves to prevent angular displacement of the 25
hook relatively'tothe ear and may also be con
veniently pressed by an operator for the purpose .
of manually disconnecting the tube frame from
the chain at any point in the length of the latter
without relying upon the clutch pin 'Hl. Fur 30
thermore, the pin 55 may if desired be relied upon
to support ‘the tube frame. when the latter is in
inverted position over the chain.
‘ Having thus described‘my invention it will be
seen that changes and 'modi?cations may be 35
made therein by those skilled in the art without
departing from'the spirit and scope of the inven
tion and I do not wish to be limited to the details
‘herein disclosed, but what I claim is:
1. In an Axminster tub'e frame, a hollow car
rier bar, an ear member ?xed thereto and extend
ing‘laterally therefrom, a supporting hook mem—
ber located entirely on that side of the ear which
facespthe longitudinal center of the tube frame,
the chain the clutch is movedinwardly or toward
the tube frame the'?rst effect of which is to
parallel to the axis of the carrier bar, and a guide
on one member passing through the other mem
latter is thereupon moved inwardly or to the
left as viewed in Fig. 1 against the action of.
spring 56 a su?icient distance to move the end
46 of the hook out of vertical alignment with
any part of the chain. The tube frame may
then be lowered in the usual manner, after which
it will be returned to the chain to cause entry
of tongue 39 between links II and 12, after
which the clutch moves away from the tube
frame and the spring 50 restores the hook 45
to its normal holding position relatively to the
chain. The loom is then ready for a repeated
operation with the same tube frame or a dif:
During’ the motion of the hook relatively to
the tube frame the guide pin 55 will remain in
the hole .56 for all positions of the hook, thereby
70 preventing ‘substantial angular motion of the
hook around the axis of stud 41 in a plane trans
verse of the carrier bar. In this way the hook
is always required to return to the link 12 in
The top 15 of the carrier bar may be slotted

nectionbetween the hook and carrier bar, the
axis of the cylindrical bearing being substantially

the opening 31 and engage the hooklunit. The
From the foregoing it will be seen that I have
provided a tube frame construction wherein the
ear 35 is durable and secured to the hollow block
25 which in turn is attached to the carrier bar.
The ear is free from the wide slot heretofore
frame. When the latter is to be removed from
lift the latter slightly by reasonof the'inclined
ber at a point laterally spaced from the cylindri- ' :
cal, bearing axis to prevent substantial angular
motion of the hook member around the cylin
drical bearing axis.,
2. In an Axminster tube frame, a hollow care
rier bar,‘ an ear ?xed with respect to the end of
the carrier bar and extending laterally there
from, a supporting hook located entirely on that
side of the ear which faces the longitudinal cen
ter of the carrier bar, means de?ning a sliding
connection between the hook and the ‘carrier bar,
said sliding connection being circular in cross
section, and }means}_ rigid with the hook and ex

tial angular motion of! the hook in a plane trans 65

3. In an Axminster tube frame, a hollow car
rier bar, an ear fixed to the bar and extending
laterally therefrom, a supporting hook located en
tirelyon that side of the ear facing the longitu 70
dinal center of the tube frame, a cylindrical slide
bearing connection betweenthe hook and car
rier bar, and a guide member on the hook sub
stantially- parallel _to the cylindrical bearing and
located at one side of the axis of the latter to pre
vent substantial angular motion of the hook in a
plane transverse to the cylindrical bearing axis,
said guide member projecting normally through
the ear to be accessible from the side of the ear
opposite to the carrier bar.

rier bar, an ear ?xed with respect to the end of
the carrier bar and extending laterally there
from, a supporting hooklocated entirely on that
10 side of the ear which faces the longitudinal cen
ter of the carrier bar, means de?ning a sliding
connection between the hook and the carrier bar,
said sliding connection being circular in cross
section, and a guide pin secured tothe hook and

faces‘ the longitudinal center of the tube frame,

and the tube frame, said slide bearing being cir
