Improvements in Temples for Looms and other like Machines.
I VICTOR MARIE HERMANN AUNAY of Rue d'Athis, Flers (Orne) in the Republio
of France Manufacturer do hereby declare the nature of this invention to be as
follows:-
My invention relates to temples for looms and other like machines and is designed
to provide temples that are simple in construction, easily attached and certain in their
action.
A loom temple constructed according to my invention is provided with rotary
conical pin rollers skewed or adjusted to rotate at any angle to the direction of motion
of the fabric. A suitable number preferably two of such rollers is provided at each
side or end of the loom so that the pins engage with the selvage of the fabric and the
rollers in their rotation tend to stretch the latter transversely.
One roller of each pair is in most cases at a lower level than the other so that the
fabric passes under one end over the other. The axis of one of the rollers of each pair
is fixed but the axis of the other roller is adjustable vertically by means of a screw or
otherwise. The bosses or studs on which the rollers rotate are carried by plates or
arms at each end of the loom which may be adjustably pivoted on a horizontal shaft
or rod extending from one end of the loom to the other so that one shaft carries both
the plates.
The pins on the conical rollers engage with the selvage of the fabric and the move-
ment of the latter causes the rollers to rotate. Being set at an angle to the direction
of motion of the fabric with their larger ends outwards the rollers tend to stretch the
fabric transversely during their movement of rotation. The rollers are preferably.
arranged one in advance of the other and the fabric may be led either over the first
roller and under the second or under the first and over the second. The bosses or
studs carrying the rollers are attached to the plate by bolts and nuts for example the
bolt of the moveable roller being adjusted by means of a vertical screw working
through the bolt at right angles. The angle at which the rollers are adjusted
relatively to the selvage is regulated according to the degree of tension.

Improvements in Temples for Looms and other like Machines.
1 VICTOR MARIE HERMANN AUNAY of Rue d'Athis Flers (Orne) in the Republic
of France 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:-
My invention relates to temples for looms and other like machines and is designed
to provide temples that are simple in construction easily attached and certain in their
action.
With these objects the temples constructed according to my invention are provided
with rotary conical pin rollers skewed or adjusted to rotate at an angle to the axis of
the loom that is to say to the direction of motion of the fabric. A suitable number
preferably two of such rollers is provided at each side or end of the loom so that the
DQ71

page_text: pins engage with the selvage of the fabric and the rollers in their rotation tend to
stretch the latter transversely.
One roller of each pair is in most cases at a lower level than the other and the
fabric passes under one and over the other. The axis of one of the rollers of each
pair is fixed but the axis of the other roller is adjustable vertically by means of a
screw or otherwise. The bosses or studs on which the rollers rotate are carried by
plates or arms at each end of the loom which may be adjustably pivoted on a horizontal
shaft or rod extending from one end of the loom to the other so that one shaft carries
both the plates.
The pins on the conical rollers engage with the selvage of the fabric and the move-
ment of the latter causes the rollers to rotate. Being set at an angle to the direction
of motion of the fabric with their larger ends outwards the rollers tend to stretch the
fabric transversely during their movement of rotation.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the several
figures on the annexed sheet of drawings the same letters of reference indicating
corresponding parts in all the figures.
Figures 1 and 2 of the accompanying drawings represent respectively an elevation
and plan of a loom temple according to this invention and Figure 3 represents the
temple in a vertical section on the line 1-2 Figure 1.
This temple is composed essentially of two rollers a and a' in the form of truncated
cones provided at their circumference with fine steel points or pointed pins as shown
in the drawing. The roller a rotates on a fixed axis but the axis on which the
roller a¹ rotates is capable of being adjusted in a vertical direction. The two rollers a a¹
seldom or never work in the same horizontal plane in practice one roller being usually
set at a higher level than the other.
With this object the rollers a a¹ are carried by a slotted support S adjustably
attached to a rod or shaft T extending from one end of the loom to the other so as to
serve for both temples one being attached to each end of the said shaft and secured in
position thereon by means of a set screw or the like. The roller a rotates on a hollow
boss provided with a collar bone side of which bears against the support S whilst the
other side is inclined and bears against the back of the skewed roller a. The form of
the collar is similar to that of the collar carrying the adjustable roller a¹ and
which is illustrated in section in Figure 3. Projecting from the collars 6 and b¹ are
turned studs 2 (Figure 3) on which the rollers a a' rotate. These studs are skewed
or inclined relatively to the support S so as to cause the rollers to rotate in planes at
a suitable angle to the line of motion of the fabric. Bolts c c¹ are passed through the
hollow bosses formed by the collars (b b¹) and turned studs 62 and through the
support S and hold all the parts together. A washer d placed under the heads of
the bolts serves to retain the rollers in position. The bolt c is simply fitted in a hole
in the support S but the bolt c¹ is passed through a slot in the support and by means
of a screw tapped in a hole in the bolt c' is capable of being adjusted vertically in
this slot so as to enable the axis of the first roller a¹ to be raised or lowered relatively
to the axis of the second roller a. These details of construction may evidently be
modified to suit the nature of the loom or other machine in which this improved
temple is employed.
The action of the temple is as follows. The edge or selvage of the fabric is passed
first over the roller a¹ and afterwards under the roller a when the fabric is heavy but
in dealing with light fabrics it is preferably passed under the first roller a¹ and over
the second roller a. The fabric being caused to travel onward by the usual action
of the loon imparts rotary motion to the roller a¹ and this roller being caused to
rotate in a plane forming an angle with the axis of the loom or line of motion of
the fabric tends to draw the edge laterally and stretch the fabric in the direction
of its width. This action is supplemented by that of the second roller a which acts
in a similar manner to the first roller a¹. The amount of tension may be regulated

page_text: according to the nature of the fabric by adjusting the roller a¹ in the slot in the
support S.
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
1. A temple for looms and other like machines in which a fabric or material
requires to be stretched transversely constructed with two rollers a a¹ provided with
pins and arranged preferably at different levels and rotating in planes inclined to or
forming an angle with the axis of the loom or direction of motion of the fabric in
such a manner as to stretch the fabric laterally or transversely substantially as herein-
before described with reference to the accompanying drawings.
2. The combinations and arrangements of parts constituting the improvements in
temples for looms and other like machines substantially as herein before described.
