"IMPROVEMENTS IN TEMPLES FOR LOOMS."
The object of this Invention is to pull the piece through the temple at each pick
and prevent its return, also to keep the weft in a straight line and prevent the
slackening of the warp of the outer edge of the piece in front of the temple
mountings.
The temple is mounted upon a rod in the ordinary way, one end of which is
carried by a link moving upon a fixed centre, provided with a stop in order to
limit the movement.
There are two dogs or ratchets mounted between the temple and breast beam,
and may be one behind the other. The object of the one nearest the breast beam,
which I call No. 1, is to pull the cloth through the temple so as to overcome the
resistance caused by the temple to the passage through it; and the other, which I
call No. 2, is to prevent the return of the cloth through the temple.
The cloth passes from the temple under the dogs or grips and forward to the
breast beam. The dog or grip No 1 is mounted so as to allow of an adjustable
vibrating or oscillating movement, which is given by the going or other part of the
loom; when, say, the going part comes forward, the dog or grip No 1 is caused to
move towards the breast beam, thus carrying the cloth forward the length of a
pick at the sides of the piece. On the return of the going part the dog or grip is
released or disengaged from the piece, and returns to its position for the next
movement. The dog or grip No. 2 in like manner rests upon the piece, and being
attached to the temple head prevents the return of the cloth through the temple,
thereby accomplishing the object of this Invention.

"IMPROVEMENTS IN TEMPLES FOR LOOMS."
The object of this Invention is to pull to piece through the temple at each pick
of the loom; and so prevent the return of the piece after the beat up of the weft;
also to keep the weft in a straight line and to prevent the slackening of the warp
at the outer edge of the piece in front of the temple mountings.
The Invention consists in mounting two "dogs," grips, or ratchets between the
temple and breast beam of the loom, so arranged that whilst one of the "dogs,"
grips, or ratchets draws the fabric through the temple, the other "dog," grip, or
ratchet retains the piece in position on the return of the going part of the loom.
Such being the nature of the said Invention, the following is a full and complete
description thereof; and in order to simplify the Specification I will describe the
temple and attachments as fitted to one side of the loom, it being well understood
that temples are required at both sides of the fabric when being woven.
In the accompanying Drawings, Figure 1 represents a front elevation of an
ordinary temple fitted with my improved attachments. Figure 2 is a side view,
and Figure 3 a plan of the same.
In carrying out my Invention any ordinary temple may be used, the one shewn
in the Drawing and indicated by the letter A is of the ordinary ring and washer
description, and which is mounted upon a rod B, one end of which is carried by
link C moving upon fixed centre C secured to bracket D attached to the breast
beam of loom; at the top of said bracket is a projection D' in which is fitted a set
screw D for the purpose of adjusting the limit of movement of bar B and
attachments thereto. The other end of bar B is carried by bracket B'. For the
purpose of regulating the temple to suit the particular with of the fabric being
I secure a sliding bracket E to rod B; this bracket has a projecting arm El
that passes through a hole in upright (F) of temple fixing; screw F also passes
through bracket E and is secured in upright F, so that by turning the said screw
to the right or left the temple upright F slides on the rod and adjusts the temple as
required.
woven,
For setting the temple A to the requisite angle with the fabric, I place the
temple slide box on pin P which acts as a centre, and secure the slide box to a
upright of temple fixing F by means of screw R passing through radial slot hole
in temple slide box flange; thus it will be seen that on loosing the said screw, the
temple can be moved round the pin P, set to the desired angle with the fabric and
secured in position by screw R.
In order to draw the fabric through the temple I mount between the temple and
breast beam of loom the "dog," grip, or ratchet G on oscillating bar H; this bar is
loose so as to oscillate on bar B, and is retained in position by spring plate fixing H¹,
which is secured to the said bar by a set screw. Centred to the upper portion of
bracket His "dog," grip, or ratchet G, which is arranged with a projection G¹
having a lug G thereon for the purpose herein-after described.
Attached to the bar H by fulcrum pin J is lever J', at the bottom end of which
is secured adjustable pin K, and when this pin is struck by the going part or other
equivalent and forced in the direction of the flying arrow, the upper end of lever J'
will press against lug G³ and cause the "dog," grip, or ratchet to slightly turn on

page_text: its centre pin and grip the fabric firmly between the bottom of "dog" at Z and
bar plate. The pin K having been so adjusted that the going part after actuating
the parts to grip the fabric as described, will cause the bar H and attachments to
oscillate a little towards the breast beam, by which means the fabric is pulled
through the temple and carried forward the length of a pick. On the return of
the going part the "dog" G releases its grip on the fabric, and the return of "dog" G
is effected by means of spring L pressing against the bottom part of oscillating
bar H forcing the same back ready for the next pick of the loom.
The fabric on the return of "dog," grip, or ratchet G is retained in its position
in relation to the temple by means of "dog," grip, or ratchet M.; this is mounted
on a bracket secured to temple bar, and is fitted with spring M₁ so arranged that
the "dog" M. keeps the fabric lying on the plate N, allowing the fabric to travel
towards the breast beam, but preventing the same travelling in the opposite
direction, as the "dog" will hold the same secure and prevent the return of the
cloth through the temple.
By this arrangement the resistance caused by the friction of the fabric in passing
through the temple is overcome, the uniform weaving of the fabric facilitated, and
a vibrating or oscillating movement is allowed to the temple and its accessories to
suit the movements of the fabric whilst being woven.
Figure 4 is a side elevation of my improved "dog," grip, or ratchet, as applied to
a templo requiring a horizontal vibrating movement. Figure 5 is an elevation
and Figure is a plan of the same. In these Figures the temples are not shewn,
being of the same construction mounted on the bar B as already described, and
the parts corresponding to those before particularised are indicated by the same
letters and figures.
The bracket S to which the "dog," grip, or ratchet is attached is mounted on
top bar T; this bar is attached to casting T¹ secured to bottom bar B; the top bar
is free to work between stops T and T³, and when the going part strikes the
adjustable pin K the "dog," grip, or ratchet G is actuated, griping the fabric as
before described, and the going part pressing the pin K forward as before
mentioned, the bar T and attachments are moved towards stop T3, the "dog" G
carrying the piece forward the longth of a pick. On the return of the going part
the "dog" releases the fabric, and the spring U forces bar T back against stop T
ready for the next pick. The "dog," grip, or ratchet is secured to the temple bar
for retaining the fabric in position as before described.
Figures 7 and 8 are modifications of "dogs" for carrying the fabric forward, and
Figure 9 is another modification and is a side elevation of my apparatus shewing
a flat grip or ratchet for drawing the fabric through the temple and carrying it
forward the length of a pick. This is effected by the going part striking the
pin K and pressing the wedge shape end of said pin against grip plate V, raising
the same and griping the fabric between top flange V₁; when thus griped the
plate V and top flange V₁ which is mounted on stud W slides on the same,
drawing the fabric through the temple the distance required. On the return of the
going part spring W₁ forces the plates back into their original position, and
spring Y forces the pin K back ready for the next pick of the loom.

manner described.
