LOOM TEMPLE

Mechanical Holding Corporation, a corporation
of Rhode Island
Application December 19, 1935, Serial No. 55,235
’7 Claims.
This invention relates to a loom temple for
holding woven fabric taut in a widewise direction
in the loom; and has for one of its objects the
arranged
provision that
of spring

may be ina such
balancing
a temple
of the
pressure between the end portions of the fabric
gripping means for holding the same taut.
Another object of the invention is the provi
sion of an arrangement by which uniform pres
1-0 sure across the engaging surfaces may be quickly
acquired by an adjustment of the parts.
Another object of the invention is the 'pro~
vision of resilient means which may be easily and
quickly adjusted to provide different desired
pressures and either the same or different at
opposite ends of the fabric engaging means.
Another object of the invention is an arrange
ment by which different pressures may be had
for different fabrics, whereby a greater tension
may be used for the heavier fabrics and a lighter
In the use of loom temples, it is frequently
desirable that different pressures be had upon
different fabrics, and also that a balanced pres- 5
sure may be had so that the pressure will be
uniform along the length of the presser mem
ber whereby a very firm grip may be established;
and in order that these results may be accom
plished, I have provided in a three-roll temple a 10
hanger for supporting and mounting the upper
roll, the same being guided towards the lower roll
in a plane passing substantially between the rolls
so that when the cloth is engaged it will be dis
posed in a sinuous path, and I have forced this l5
carriage with the upper roll downwardly towards
th-e lower roll by a pair of springs which are dis
posed in alignment with each other and also sub
stantially in the plane of movement of the hanger
so as to act directly from above the roll in forc~ 20
ing it downwardly towards the lower roll; and
of a means whereby the resilient pressure may
be distributed against the member which con
tacts the upper surface of the cloth so that an
even pressure along the surface may be obtained.
trating the preferred means by which these ad
vantageous results may be accomplished:

Another object of the invention is the provision
30 gaging the upper surface of the fabric from di
rectly above this member so as to force the
same downwardly from this superimposed posi
tion in substantially the direction it would travel
by gravity.
With these and other objects in View, the in
vention consists of certain novel features of con
struction, as will be more fully described, and
particularly pointed out in the appended claims.

the following is a more detailed description of
he present embodiment of this invention, illus
with an arm Il extending to the bracket l2 for
securing the temple in position.
rI‘his base is cast with recessed portions I5 and 30
I6 for the reception of the rolls Il and i8, which
are mounted on the axles I9 and 20 extending into
bearing supports 2| in one end wall 22 and simi
lar bearing supports 23 in the end wall 24 at
the other end. The axles threadingly engage one 35
of said supports and are provided with a slotted
end 2l for easy rotation. These rolls are thus
mounted in spaced relation and provide spaced
engaging surfaces for the traveling fabric or
web 25 which passes throughthe temple. The 40
surfaces of the rolls are grooved as at 25 in a
known manner to better grip the fabric.
Mounted upon the base there is a cap member
designated generally 3G, and shown in perspec
tive in Figure 7. This cap member has a tongue
portion 3| to fit within a groove 32 in the base,
while an opening 33 receives a bolt 34 which may
-be threaded into the base as at 35 to securely
bind the cap member in superimposed relation
over and spaced from the base. The opposite 50
edges 36 and 31 of the cap are suitably rounded
to engage the cloth and with the rolls will dis
pose the fabric web in a more or less sinuous path
depending upon the thickness of the cloth.
Within the cap 30 there is mounted a hanger

40 which may move vertically in the guideways

and 44 at one end and 45 and 46 at the other

end. This hanger is provided with depending
portions 4l, 48 at its opposite ends, which pro
vide bearings 49, 50 for a readily removable
The foregoing description is directed solely to
wards the construction illustrated, but I desire
spindle 5l upon which the upper roll 52 is rotat
ably mounted. This spindle is threaded as at 53
which engages the thread in the opening 50 to
hold the same in position. An enlarged slotted
head 54 is provided at the end of the spindle
for manipulation by a screw driver for inter
changes of upper rolls. A bar 56 extends later
ally across the hanger 40 and beyond the sides
of resorting to all the mechanical changes to
which the device is susceptible, the invention be
ing defined and limited only by the terms of the
thereof to engage the abutments 51 on the op
mounted by said hanger, and a pair of elongated
aligned arched springs each acting on said
hanger solely at its end extremities to apply
pressure thereto at a plurality of spaced points
directly above the hanger roll and in the plane
of its movement for moving'said hanger in said 20
posite sides of the guide portion 4l, while a bar
58 extends across the hanger at the opposite end
for engaging the abutment 59 to support this
end of the hanger against dropping from the
20 cap.
The stops 56 and 58 are normally positioned well
above their abutments 51 and 59 and the hanger
is forced downwardly by two leaf springs 69 and
6I which are convex on their upper surface and
25 concave on their lower surface providing spaced
portions 62 and 63, 64 and 65 which engage at
aligned points along the top surface of the hanger
4D so that when pressure is applied to the upper
side of the spring at a point substantially half
30 Way between the points of contact, the springs
will be forced downwardly against the hanger
while in turn forcing the roll which it supports
downwardly in a plane substantially between the
rolls Il and I8 so as to cause any fabric passing
35 between these rolls to be iirmly gripped thereby.
In this manner, the pressure is located in sub-
stantially the direction or plane of the path of
movement of the roll and is generally directly
above it.
40
therein at the initial setting up of the loom and
placing the fabric in the desired position to deter
The threaded member 66 engages the upper
portion of the springs 60 and Bl and has a slot
in its head 61 so that it may be threaded down
wardly through the threaded opening 68 in the
bridging portions 69 and 10 of the cap to adjust
the pressure upon the spring to the desired
amount, which pressure having been obtained
the hexagonal lock nut 'l2 is forced against the
surface 13 of the bridge to hold this threaded
member 66 in desired position for adjustment.
In order to prevent the springs from longi
tudinal movement or slipping from position, a
screw 14 having a head 15 passes through an
opening in the spring and into the pressure
member 66 so as to hold the spring in desired
Ul il: position in the temple.
This threaded screw 14
will not be caused to bind the spring against the
bottom of the threaded member 66 but rather
will permit rotation of the threaded member 66
without twisting the spring or turning the spring
(Si) with it, by reason of a swivel arrangement.
By the construction provided, I may adjust the
springs 60 and 6I so that they have the same
amount of tension or they may be adjusted to
have different amounts of tension, depending
upon the objects desired to be accomplished.
When set in their adjusted position the springs
remain set at a fixed pressure until a change
in the character of the fabric is made or a diiîer
ent pressure is desired. Thus, it is a simple
matter to obtain the desired pressure adjustment
after the temple is in position in the loom and
after the fabric has been inserted through the
rolls by a proper turning of the threaded members
66 so that it becomes unnecessary to take olf the
75 cap for the preliminary insertion of the fabric
it to be understood that I reserve the privilege
appended claims.
