BEAM LOOK
Moten E.‘ Tanner, Spartanburg, S. 0.
Application October 16, 1937, Serial No. 169,342
2 Claims. (or. ‘ans-24)
I This invention relates to a beam look for looms
which-is used {for holdingthe journals of a warp
beam shaft ‘securelyin the bearings. In the oper
ation of ‘looms ‘considerable wear is caused on the
journal of the‘ warp beam shafts, resulting in a
loose ?t between the shaft and its bearings. When
the loom'fis in‘ operation, vibration of the entire
beamJWiILF'therefOre, take place and affect the
tension of the warp, which, in turn, will produce
10 a. defective cloth.
It is, therefore, an object of this invention to
provide a simple and e?'icient beam lock which is
capable of adjustment to hold the warp beam for
rotation and yet eliminate this play. This par
1 GI ticular form comprises a bearing cap which is
the same is placed into the bearing portion l 5.
This portion also acts as a rest for the ends'of the
shaftwhen removing the loom beam.
,
Although only a portion of one side of a loom is
shown'in the drawing, it is evident that a similar ;
bearing is placed on the'other side for supporting
the other end of the warp beam‘.
This part on
the other side is identical,-except that it is-o'ppo
site handed and therefore, a showing and descrip
10
tion is not thought to be necessary.
When the journals of the beam are placed in
the bearings 15 it is then necessary to clamp the
upper side thereof tightly in position. At this
time, a semi-circular bearing cap 2| is placed
upon the upper side of portions l3 and M of the
bodily movable relative to the bearing and which
warp beam shaft, said bearing portion being inte~
may be adjusted thereon to compensate for any
wear which takes place upon the journals of the
warp beam or upon the bearings in which they
20 rotate, or to accommodate different sizes of jour
nals.
It is a further object of this invention to provide
a beam lock which can be quickly and ef?ciently
operated when it is desired to remove and replace
25 a warp beam and which permits the removal of
the same without detaching the beam lock from
the frame of the loom.
gral with one side of lever 23 and extending later
ally therefrom. This lever has a suitable slot 26
Some of the objects having been stated, other
objects will appear as the description proceeds
3 O when taken in connection with the accompanying
drawing, in which:
.
Figure 1 is an elevation of an end portion of a
warp beam, associated with a loom frame and
showing my invention applied thereto;
35
Figure 2 is a vertical, sectional view taken along
the lines 2—2 in Figure 1;
Figure 3 is a sectional, plan view taken along
the line 3—3 in Figure 1;
Figure 4 is an exploded isometric View of the
40 beam lock and its associated bearing;
Figure 5 is an inverted isometric view of the
beam lock cap.
Referring more speci?cally to the drawing the
numeral l0 denotes a warp beam which has a
4
therein which is normally penetrated by a bolt 25.
This bolt is also adapted to penetrate hole 26 in
the bracket I6. The other end of the lever 23,
that is the end nearest the observer in Figures 1
and 3, has a down turned hook portion 21, and
this hook portion is adapted to ?t underneath
?ange l6a of bracket l6 when the cap is in a ?xed
position. When it is desired to adjust the bearing
cap 2| and lever 23 so as to compensate for the
Wear between the bearing portion 15 and the
journals l3 and I 4, it is only necessary to loosen
the nut on bolt 25 and rotate the lever 23 in a
counterclockwise manner (Figure 2) about the
hook portion 21 and then again tighten the same.
On the other hand, when it is desired to remove
the warp beam from the bearing it, it is only
necessary to loosen the nut on bolt 25 so that the
hook portion 21 may be pulled laterally out from
beneath the outstanding ?ange its. Then the
lever 23 along with the bearing cap 2! may be
rotated in a counter-clockwise manner about bolt ’
25 until the ends of the warp beam shaft may be 40
removed.
By observing Figure 5 it is seen that the bear
ing portion 2la of lever 23 is of a slightly greater
radius than the bearing portion 2th. This dif
ierence in the bearing portion is provided so that
head H, friction drum l2, and a central shaft l3,
said shaft having a restricted end journal portion ' a suitable shoulder 2lc will be present when the
lever 23 and cap 2| are in a ?xed position in
M. The portion I3 is adapted to rotate in semi
order to. prevent longitudinal movement of the
circular bearing portion l5, which portion is inte
gral with the upper portion of bracket It. This beam shaft I3 and its restricted portion l4. Of
50 bracket is secured to the side-frame ll of a loom course, the radius of the bearing portion 21a is 50
by any suitable means such as bolts l8, which bolts substantially the same as the radius of portion l3
are adapted to penetrate slots IS in the brackets, of the beam shaft, whereas the radius of the por
and also the frame H. of the loom. The bracket tion 2th is substantially the same as that of the
l6 also has a rest portion 20 which is adapted to restricted portion M of this same shaft.
It is thus seen that I have provided a beam rest 55

and lock which is capable to being attached to
any loom, and also which enables an operator to
‘remove the beam easily and quickly, without en
tirely detaching the beam lock from the frame
of the loom.
I have also provided a beam rest which tightly
adapted to ?t beneath said rib on the bracket
and having a vertically disposed slot in its other
end, a bolt penetrating said slot and said bracket,
which bolt when its nut is'driven home serves tov
hold the hook beneath the rib on the bracket
and to thus hold the member in a position to con

in the bearings, yet permitting the rotation of the

brackets provided with semi-circular upwardly 10

vention, and although speci?c terms are em

I claim:
1. In a loom having a pair of brackets secured
20 to the frame of the loom and each being provided
with an upwardly opening semi-circular cavity
to serve as a bearing portion for the journals of
a warp beam, and also having a rib projecting
from one side thereof, means for-releasably lock

comprising a member provided with a down

said member having an inturned hook on one end
bracket having an outwardly projecting rib along
the outer upper edge thereof, a member asso

ciated with each bracket for holding the journals
in said semicircular bearing portions, said mem
ber having a semi-circular bearing portion along
its lower edge and having a vertically disposed
slot in one end and having a laterally projecting 20
lip on its other end adapted to ?t beneath said
rib on said bracket, and a bolt penetrating the
slot in the bracket and said slot in the member
for holding one end of the member against said
bracket and for also holding said laterally pro
jecting lip beneath said rib to prevent upward
and lateral movement of the said member.
