Improvements in or connected with the Temples of Looms for
Weaving.
I, FRANK JEROME DUTCHER of Hopedale, County of Worcester, in the State
of Massachusetts one of the United States of America, Manufacturer do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
In the use of loom temple rolls with different kinds of cloth, much difficulty has
been experienced by reason of the marks which are left by the teeth of the rolls
on thin fine goods, and with heavy, closely woven cloth the rolls heretofore have
failed to take proper hold, particularly at the selvages, which latter curl up, so that
cloth with straight selvages cannot be made.
My present invention has for its object the production of a temple roll which
will overcome the beforenamed objections, and means are also provided whereby
the wear on the bearings or journals of the temple roll is also decreased.
One part of my invention therefore consists in a temple roll provided for a portion
of its length with teeth of equal height from the surface of the roll, the teeth
gradually decreasing in height therefrom towards the end of the roll, substantially
as described.
Also, in a temple roll provided for a portion of its length with teeth of equal
height from the surface of the roll, the teeth gradually decreasing in height
therefrom towards the end of the roll, the number of teeth being increased towards
one end of the roll, substantially as described.
Also in a temple roll having an increased number of teeth towards one of its
ends and decreasing in height from the surface of the roll towards such end, the
remaining teeth being of equal height, substantially as described.
Also, in a temple roll provided with teeth gradually decreasing in height from
the surface of the roll towards one of its ends, substantially as described.
Also, in the use in a loom temple having a pod and cap, and bearings for the
roll, of a temple roll having a bushing bored to receive the bearings and projecting
beyond one end of the roll, and a protector counterbored to receive the projecting
end of the bushing, substantially as described.
Also, in the use in a loom temple having a cap provided with bearings, of a
temple roll having a bushing to be entered by said bearings and projecting beyond
the inner end of the roll, and a protector interposed between the inner end of the
roll and the cap and enclosing the projecting portion of the bushing, substantially
as described.
Also, in the use in a loom temple having a cap, of a temple roll rotatably
supported therein, a bushing in the roll projecting beyond its inner end, and
a counterbored plate to receive the projecting bushing and take up the end thrust
thereof and to protect the bearing, substantially as described.
Fig. 1 is a vertical longitudinal sectional view of a temple roll embodying my
invention, the pod and cap being shown in section;
Fig. 2 is a side elevation of the temple roll, to more clearly show the arrangement
of the teeth;
Fig. 3 is a transverse section taken on the line - Fig. 1, looking to the
right;
Fig. 4 is an enlarged inner side perspective view of the dust protector for the
roll journal, and

page_text: Fig. 5 is a rear end elevation of the pod and cap, with a portion of the supporting
shank.
Referring to Figs. 1 and 5, the inner end of the pod a, forming a part of the
shank a', is transversely slotted at a² to receive a locking ear 6 formed on the
cap b, the latter in this instance supporting the temple roll.
A lug on the cap, see Fig. 5, rests on the enlarged end a³ of the shank, when
the cap is in operative position, a bolt passing through the lug and into a
threaded hole in the end a retaining the cap rigidly in place.
The inner end of the cap is downturned at a', and threaded to receive aud
support one of the pivots or stud bearings c of the temple roll d, a similar
pivot or bearing c¹ being held in the outer end of the cap, as clearly shown
in Fig. 1.
I have herein shown the temple roll as provided with bushings do, axially
bored at the ends to receive and freely turn upon the smooth inner cuds of
the stud bearings c c', the end of one bushing projecting beyond the end of the roll,
as at dx.
It is found in practice that lint, dust, etc., are apt to collect about the inner end
bearing of the usual temple roll, and I have obriated this by extending the bushing
as at d, and inserting it loosely in the counterbore e¹ of a protector e, shown
separately in Fig. 4.
This protector is preferably made of brass, or other suitable metal, with laterally
extended wings e, which enter between the edges of the cap and pod, holding it in
place, the bearing or pivot c passing through a hole in the protector, the
latter also taking up the end thrust of the temple roll when in use.
By this means the necessary longitudinal play of the roll is permitted while
effectually protecting the bearings from the entrance of lint or dirt.
In weaving heavy, closely woven cloth it is found that if the teeth of the roll are
reduced in number at the outer end of the roll, as at-d', Fig. 2, they take a much
better hold of the cloth along the selvage, and slack selvages can then be held
properly, thus preventing the curling up of the selvage.
With the usual temple roll, baving the teeth disposed equally from end to end
the teeth cannot properly enter and take hold of slack selvages, and cloth with
straight selvages cannot be woven.
I also prefer to make the teeth at the outer or selvage end of the roll of uniform
height, the teeth gradually decreasing in height from about the point d², Figs. 1
and 2, to the inner end of the roll.
This prevents the teeth at the inner end of the roll from taking the greatest hold
of the cloth and marking it, for the gradually decreasing height of the teeth
towards the inner end of the roll causes them to take a gradually diminishing hold
on the cloth inwards from the selvage.
When weaving thin, fine goods, the arrangement of the teeth as to number is
reversed, that is to say, the teeth are set closer together at the selvage end, so that
a greater number engage the cloth at any one time, and being set closer together
they cannot enter so deeply into the material, thus avoiding marking.
Furthermore, the close setting of the teeth enables them to let go of the fabric
more easily as the cloth is moved along.
The arrangement of the teeth as to height is, however, the same as heretofore,
the teeth decreasing in height from the vicinity of the middle of the roll to the
inner end, as described.
This tapering of the teeth, as it may be termed, decreases the pressure of the
cloth on the inner end of the roll and so decreases the wear on the bearing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that. what I
claim is :-

2. A temple roll provided for a portion of its length with teeth of equal height
from the surface of the roll, the teeth gradually decreasing in height therefrom
towards the end of the roll, the number of teeth being increased towards one end
of the roll, substantially as described.
3. A temple roll having an increased number of teeth towards one of its ends
and decreasing in height from the surface of the roll toward such end, the
remaining teeth being of equal height, substantially as described.
4. A temple roll provided with teeth gradually decreasing in height from the
surface of the roll towards one of its ends, substantially as described.
5. The use, in a loom temple having a pod and cap, and bearings for the roll, of
a temple roll having a bushing bored to receive the bearings and projecting beyond
one end of the roll, and a protector counterbored to receive the projecting end of
the bushing, substantially as described.
6. The use, in a loom temple having a cap, provided with bearings, of a temple
roll having a bushing to be entered by said bearings and projecting beyond the
inner end of the roll, and a protector interposed between the inner end of the
roll and the cap and enclosing the projecting portion of the bushing, substantially
as described.
7. The use, in a loom temple having a cap, of a temple roll rotatably supported
therein, a bushing in the roll projecting beyond its inner end, and a counterbored
plate to receive the projecting bushing and take up the end thrust thereof and to
protect the bearing, substantially as described.
