Figure 7 is a perspective View illustrating one

Figure 8 is a fragmentary plan view illustrat

Referring in detail to the drawings, the nu
meral i indicates a cylinder equipped with slots 2
for the attaching of a warp on said cylinder and
40 adjustable relative to each other and on the
cylinder are warp flanges 3. Said flanges 3 may
be accurately adjusted towards and from each
other to accommodate on the cylinder warps of
different widths and act to properly center a
warp on the cylinder.
Mounted on the ends of
the cylinder are tension drums 4 each provided
with peripheral spaced flanges 5 and each in
cluding inner and outer annular elements 6 and
'I. The inner annular elements B are centrally
50 apertured to receive pintles 8 employed for rotat
ably supporting the beam on a loom and each has
an integral collar 9 arranged in abutting engage
ment with the inner annular elements E. The
inner annular elements 6 are provided with pe
ripheral flanges IU which frictionally engage the
meshing with said threads are feed nuts i4 pro- 20
vided with extensions I5 that project through
slots i6 formed in the cylinder. The extensions
i5 are of tenon shape and the warp flanges are
grooved to receive the extensions I5 thereby
establishing a dove tail ñt between the extensions 25
and the Warp flanges.
The extensions are de
tachably secured on the warp flanges by stud
bolts Il. Meshing with the threads of the feed
shaft I2 are lock nuts I8 adapted to be turned in
engagement with the feed nuts after an adjustment of the warp flanges relative to each other
has been made for the purpose of securing the
warp flanges against accidental movement rela
tive to each other or on the cylinder. The lock
nuts have wrench engaging faces se that a
wrench or similar tool can grip the latter by
entering the cylinder by Way of the slots I6.
Pinned on the feed shaft I2 are collars I9 which
engage with the tension drums to prevent end
Wise movement of the feed shaft. Thus it will
be seen that by rotating the feed shaft I2 in
opposite directions, the warp flanges may be
moved towards and from each other on the
cylinder for the purpose of accommodating warps
of different widths and after an adjustment has
been made said warp flanges can be secured

against accidental displacement by turning the
lock nuts I8 against the feed nuts I ll. Formed
in the warp flanges are chambers 2t and are
located opposite to the feed nuts. Slidably 50
mounted in the chambers and arcuately curved
to conform to the contour of the cylinders are

outer annular members 6 and 'l are secured to
gether by keys 28 held by set bolts 29. The ends
of the set bolts 29 are arranged inwardly of the
peripheries of the tension drums and are of the
socketed type to permit a wrench to be applied
thereto.

shown in Figure 2. Secured to the inner wall of slidable on said cylinder, feed nuts engaging the
the cylinder and projecting beyond opposite feed shaft and extending through the slots and
shoes on the cylinder may be varied by the ad
justment of the set bolts.
Used in connection with the beam is a plu
rality of closure plates of various lengths one of
which is shown in Figure 7 and designated by
the character 24. After the adjustment of the
15
edges of the slots are ears 25 to form seats for
supporting the closure plates and each closure
plate has detachably secured thereto a bridge 26
which may be brought into engagement With the
inner walls of the cylinder after the positioning

the ears 25 in preventing accidental displace
ment of the closure plate.
The inner annular elements ß are secured on
the pintles 3 by keys 2? and engaging with said
keys are set bolts 28 to prevent the pintles and
annular elements from becoming accidentally
secured on said Warp flanges, said Warp flanges
having chambers, adjustable pressure shoes
mounted in said chambers and bearing against
said cylinder, ears formed on the inner face of
the cylinder adjacent the slots, removable closure
plates for closing portions of the slots lying be
tween the Warp flanges and engaged by said ears,
and retaining elements pivoted on the plates to
be positioned to engage the cylinder and cooper
ate With the ears in removably mounting the 25
plates on the cylinder.
