WARP BEAM AND- DIETHOD‘ OF MAKING
Oscar V. Payne, Leicester, Mass, assignor to
Gro'mpton & Knowles Loom Works, Worcester,
Mass, a corporation of Massachusetts
Application December 24, 1935, Serial No. 56,041
(Cl. 242-—124)
4 5‘ Claims.
This invention relates to. improvements in warp
beams for looms and it. is. the general object of
the invention to provide a strong durable beam
which. is of comparatively light weight because
of its simple construction. '
Warp beams. ordinarily comprise a barrel hav
ing sliding warp. heads movable to vary the width
of. the warp space. It is‘an important object of
my present invention to form a warp head with
two disks one of which is perpendicular to the
axisof thev beam and the other of which is dished
orlconical, the two disksbeing secured together
by a spacing sleeve and tapering toward each
other from the barrel toward the outer rim. The
sleeve prevents crushing of the flat disk by pres
conical. disk to serve as guide means for the sleeve
so that the latter can be spaced from the warp
surface of the barrel and secured to the conical
disk while being so located. The method there
after contemplates welding or otherwise securing
the sleeve to the ?at disk along an area between
the barrel and sleeve with subsequent rolling or
pressing the edges of the ?at "disk around the rim
of the conical disk.
With these and other objects in view which will‘ I
appear as the description proceeds, my invention
resides in the combination. and arrangement of
parts set forth hereinafter.

the gudgeon ?ange, orthe' type of let-off vshown

the‘beam, when in the loom, can be used with
two different types of let-off;
It is a stillv further object of my invention to
provide an. improved method for assembling the
warp head, the method involving the steps of
securing: the clamp bolt retaining: blocks. to. the

Referring to the drawings, the beam barrel I0
is made preferably of pipe and has. its outer sur
face ground to present a smooth uniform surface to $1
to. the warp threads. Since both ends of the
beam are alike but one end will be described‘. A
supporting gudgeon H, as shown-in Fig. 1, com
prises a stem I! turned to be true and receivable
by'a- bearing either in. the winding machine or 110
the loom. A thin flange. l3. integral with. the
stem has its. periphery turned. on the gudgeon
centers to ?t the internal diameter of the pipe.
-By means of a jig not. shown the gudgeon axis is
aligned with the, pipe axis, and in this‘ position
the ?ange is‘ welded to the interior surface‘ of
the barrel pipe. A beveled edge on the ?ange,
indicated at M in Fig. 1, provides room for the
welding metal. In this way the gudgeon is ?rm
ly secured to- the end of’ the pipe» with its axis '
true with: that of the pipe. The latter may then
be turned about the gudgeon axes and given a
true; smooth Warp receiving surface of vdesired
size. Reinforcing integralradiating webs. l5. may

the stem be subjected to a severe blow..
When the beam is to be used in a 100m having
an ordinary'friction let-off, a friction head 28
with a cylindrical shell 2! will be provided. The
shell will have a polished surface 22 and will be '
formed with a web 23 through which extends
10 bolts 24. The bolts are tapped into the ?ange l3
so that the friction head is tightly secured to the
barrel. The arrangement of the bolts and shape
of the web 23 may be as shown in Fig. 3. The
friction head is formed with a shoulder is which
The depression also has a use to be set forth here
inafter.
In order that the head 30 may assume differ
ent longitudinal positions along the barrel I pro 10
vide a clamp designated generally at 50. This
clamp has two heads 5| and 52. separated by a
narrow slot 53 and connected by a bolt 54
threaded into head 52 and having a head 56
?ts closely around the end of the barrel to center . which shoulders against the head 5|. By slack 15.

the head with the barrel axis; In this connec

35 a planate portion 35 substantially perpendicular
to the axis of the barrel. The rim 33 is caught

Welding, as desired, and may also be ?attened, as
shown in Fig. l.
a
In order to reinforce the two disks a cylin
drical sleeve 49 is interposed between the ?ange
disk 3! and the ?at part 35 of the conical disk;
the sleeve having an internal diameter somewhat
greater than the external diameter of ‘the barrel.
A pair of blocks 4! and 42 are welded to the
inner surface of the planate part 35 of the conical
disk, and lie preferably against the sleeve. In
this way the blocks locate the ‘sleeve so that
it is held spaced from the outer warp surface of
the pipe._ The disks 3i and 34 have aligned
barrel receiving bores 45 as shown in Fig. 1.
The method of assembling the warp head is
shown in Figs. 5, 6 and '7. The blocks 4| and
42 are welded to the planate part 35 of the conical
tive movement of the clamp with respect to the
30
axis of disk 34, thereby permitting the internal
bore 35 of the clamp to fit closely against the warp
barrel under slight‘ tightening of bolt 54. When
the screws 60 are tightened in place they hold 35

In‘order to provide the barrel with'a smooth
surface the pipe of which it is constructed. is
ground or turned down to size. If for any reason
the pipe should be twisted’ there isthe likelihood 45
that part of the barrel will be thin. In such a
case a clamp‘suc-h as that shown in' Fig. 72 con
centrates the pressure of 'the screw 54 at one
point on the periphery of the barrel and I have
found in occasional instances that a slight eccen
tricity of the barrel results. In order to distrib-‘
ute the pressure incidental to tightening. the
clamp over a larger area-I employ the modi?ed
form shown in Figs. 9 and 10. The modi?ed
clamp Ill may be similar to the preferred form 56
in all respects except the manner in which the
disk one on each side of the bore 45, as shown , head is split‘. In this instance instead of having

disk 39 is then placed with its bore aligning with
that of the other disk, the rims 32 partly rolled,
.as shown in Fig. '7; ’ The sleeveis then welded
to the ?at disk, along an area lying between bore
45 and the sleeve, after which the rims’ are pressed
tightly in place, as already described and shown
in Fig.1. The greaterinternal diameter of the
sleeve provides room for this last weld, and also
keeps any. roughness which might accompany
pressure isrnot concentrated as in the form shown
in Fig. 2 but is distributed with the result that
the eccentricity of_ the barrel due to the tight
setting of the clamp is very materially reduced. 70
The modi?ed form of clamp will be set in arman
ner similar to that described in connection with
the preferred form and will differ from the latter
only in the direction of the slot ‘ll.
From the'foregoing it will beseen that I have '75

‘outer rims of which are secured together by substantially equal distances from the latter, a

2. A warp beam head adjustable longitudinally
It will also be seen that the gudgeon is formed
10 with an integral ?ange which ?ts into the end
of the barrel and is welded around its periphery
to provide a strong bond. Also, it will be seen
that the clamp is held to the conical or dished
disk by screws which pass through holes in the
15 clamp large enough to permit a slight relative
movement of the clamp relatively to the disk,
and that the clamp is further provided with a
tightening bolt. The bolt can be used to eifect
a partial tightening of the clamp so that the
20 latter has a close ?tting contact with the barrel
surface before the screws are tightened, the loose
?t between the screws and the clamp permitting
the latter to ?nd its center around the barrel,
after which the screws may be tightened to hold
the clamp against the conical disk. The bolt is
subsequently tightened to hold the clamp against
the barrel without unequal strain which might
otherwise arise but for the relative movement
of the clamp with respect to the screws. Fur
ther, the blocks which receive the screws for the
clamp serve also to position the sleeve which is
secured to and reinforces the two disks forming
the warp edge. Again, the ?ange of the gudgeon
provides the beam barrel with a square end
adapted for ?tting either with the common let
o? friction head or the positive let-off shown in
myPatent No. 1,803,143. Lastly, it will be seen
that the advantages growing out of the con
struction of the warp head are attain-ed by fol
40 lowing a method of construction wherein blocks
are secured to the conical disk to position the
sleeve, the latter being then welded to the conical
disk, afterswhich the ?at disk is welded to the
along a hollow metallic barrel comprising adisk 10
with a conical portion forming part of the warp
beam head, blocks secured to the disk on oppo
site sides of the barrel axis, part of the conical
portion of the disk being recessed to position one
of the blocks, a clamp, means to secure the clamp 15
to the blocks, and means accessible from a point
adjacent the recessed part of the conical por
tion to tighten the clamp on the barrel.

the barrel, said heads being separated by a slot
oblique with respect to the head axes and lying
in a plane transverse of the axis of the barrel, a
portion of the circumferential periphery of the
barrel being engaged by parts of both heads
lying on opposite sides of said slot, and means 30
