Improvements in Temple Bars, Temples, and Means for Guiding
Shuttles of Power Looms.
I, JOHN MCBURNEY, Power Loom Tenter, 36, Magdala Street, Belfast, do hereby
declare the nature of this invention to be as follows;-
This invention relates to power looms and it has for its object to improve their
construction.
In carrying out the first part of my invention I make the temple bar with
two slots near each end so that slightly wider or narrower widths of cloth can be
worked in the loom without undoing the temples. Bolts and nuts are or may be
provided for adjustment.
The second part of my invention relates to the temples themselves. At present
the temples are so made that it is difficult for the weaver to vary the widths.
Under my invention the temples are made of an L shape and are adjustably
secured to the temple bar by means of a screw clamp arrangement. This screw
clamp consists of a clamp piece having a V groove in it which grasps the edge of
the temple bar and also grasps the narrowed or reduced end of the foot or
short leg of the temple. This short leg of the temple is cut out for the reception
of the temple bar. The screw of the clamp is fitted in the short leg of the temple
and its end passes through a hole in the clamp piece and is secured by a nut or
equivalent.
The temples are preferably made in two halves locked together and the upper
half is provided with one or more slots cut slightly at an angle and towards the
front so that the weaver can easily see the cloth without bending over the temples
and looking down through the apertures.
The third part of the invention consists in attaching to the front of the loom
two attachments whereby the shuttle, as it approaches the selvedges of the cloth,
is caused to move gradually and steadily instead of with a jerk. The attachments
consist of two brass or other strips arranged one at each side of the loom and
secured in position by bolts and nuts passed through transverse slots. The strips
taper in thickness and also in width from their inner to their outer ends.
extreme inner ends may be sharply cut or tapered off. When these attachments
are used a nicer selvedge is produced, there is less wear and tear on the reed, and
the shuttle is not so liable to fly out.

I, JOHN MCBURNEY, Power Loom Tenter, 36, Magdala Street, Belfast, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement;-
This invention relates to power looms and it has for its object to improve certain
features of their construction.
And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a plan view of a temple bar with my improved temples attached thereto.
Fig. 2 is an end view of same.

Fig. 3 is a side view of a temple as it appears when inverted.
Fig. 4 is a plan view of a temple with the cover plate removed.
Fig. 5 is a cross section taken on the line xx Figs. 1 and 4.
Fig. 6 is an elevation and Fig. 7 a plan of the attachments for guiding the
shuttle.
In carrying out the first part of my invention I make the temple bar a with
two slots b, b, near each end so that slightly wider or narrower widths of cloth
can be worked in the loom without the necessity of undoing or removing the
temples as at present. When the springs care merely secured by bolts passed
through holes in the temple bar then the temples cannot be slid along the bar
further in than the bolts c for the purpose of doing narrower widths owing to
the bolts stopping them. By providing slots however the bolts c can be slackened
and then shifted to the ends of the slots so as to allow the temples to be moved
inward to a further extent. When the temples are at the inside of the bolts c the
same remarks apply and by shifting the bolts c outwards in their slots the temples
can be shifted correspondingly and slightly broader widths of cloth woven without
the necessity of undoing the temples and re-securing them outside of the bolts.
The second part of my invention relates to the temples themselves. At present
the temples are so made that it is difficult for the weaver to vary the widths.
Under my invention the temples d, d', are made of an L shape and are adjustably
secured to the temple bar a by means of a screw clamp arrangement. This screw
clamp consists of a clamp piece e having a V groove e¹ in it which grasps the edge
of the temple bar a and also grasps the narrowed or reduced end f₁ of the "foot"
or short leg of the temple. This short leg of the temple is cut out at f2 for the
reception of the temple bar a. The screw g of the clamp is fitted in the short leg
of the temple and its end passes through a hole in the clamp piece e and is secured
by a nut or equivalent.
The temples d, d', are preferably made in two halves i, ¹, locked together by
means of a bolt 22 and nut 3 and the upper half or cover is provided with two
or more slots j cut slightly at an angle and towards the front, as shown, so that
the weaver can easily see the cloth without bending over the temples and looking
down through the apertures. The temples are provided with the ordinary toothed
roller kas shown at Figs. 4 & 5.
The third part of the invention, as shown at Figs. 6 and 7, consists in attaching
to the front of the loom two checking attachments whereby the shuttle, as it
approaches the selvedges of the cloth, is caused to move gradually and steadily
instead of with a jerk. The attachments consist of two brass or other strips 1, 11,
arranged one at each side of the loom and secured adjustably in position by

page_text: bolts m passed through transverse slots n. The strips taper in thickness and also
in width from their inner to their outer ends as is clearly shown in the figures.
The extreme inner ends may be sharply cut or tapered off as shown at o.
When
these attachments are used, owing to the fact that the shuttle 12 is gradually
checked by the bearing surface of the strips, a nicer selvedge is produced, there
is less wear and tear on the reed, and the shuttle is not so liable to fly out. The
bearing of the strips on the shuttle can be regulated by the bolts and slots m, n.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:
-
1. A temple bar made with slots b, b, substantially as hereinbefore described
with reference to the drawings annexed and for the purpose set forth.
2. Temples constructed substantially as herein before described with reference to
Figs. 1, 2, 3, 4 and 5 of the drawings annexed.
3. The attachments 1, 1, for power looms substantially as and for the purpose
set forth.
Dated this 29th day of June 1898.
