ABRAHAM SMITH of Bingley in the County of York: Manufacturer IMPROVE-
MENTS IN LOOMS FOR WEAVING
., The object of this invention is to arrange the Reed fast when required; to be so,
and loose when so required...
When the shuttle is home in either of the Boxes and the going part of the Loom
is beating up the weft, the reed is fast but when the shuttle is passing, from Box.to
Box the reed is loose.
.
.
The arrangements hitherto for accomplishing the above consists in a rod passing
from end to end of going part with fingers to hold the reed fast in the case of a
loose Reed and in case of a fast reed there are frogs, on each end of the frame
with 'catches which when actuated bring the loom to a stand causing a very sudden
checking of the whole machine. In my arrangement the Frogs and catches in the
case of a fast Reeds are, dispensed with..

1 accomplish, my object in the following manner-To the going part of a loom, I
mount a plate behind the reed for its entire length: to this, plate I,attach two
or more levers passing under to and beyond the front of the going part, this
lever terminates in a "gib" end: the underside of this gib ended lever comes in
contact with adjustable springs or brackets attached to the breast beam. When the
going part, with levers come, in contact with springs or brackets the levers are
raised bringing the plate against the bottom part of the reed and securing it, that
is, at the time when the shuttle is home in one of the Boxes, when the going part
returns the plate is relieved from the reed and the same is then loose that is when
the shuttle is traversing across the warp, thus giving a fast and loose Reed
alternately when required.

required during the "beat up" of the weft: and loose whilst the shuttle is passing
through the warp "shed."

I accomplish my object in the following manner-To the going part or sley
beam of the loom, I mount a plate behind the reed, which extends for its entire
length, and is connected by two or more levers to the ordinary rod mounted to the
underside of going part or sley beam. To each of these levers is jointed a catch
rod that extends through and beyond the front of the going part, terminating with
a "gib" end: these catch rods are raised immediately before the weft is "beat up,"
thereby securing the reed by means of the gib heads passing up in front of plates
secured to the going part.
On the return of the going part, the catch rods lower to their normal position
when the reed is loose, that is, when the, shuttle is traversing across the warp: thus
giving a fast and loose reed alternately when required.
In order that my invention may be better understood I have appended here-
unto one sheet of drawings marked with letters of reference, corresponding letters
indicating the same parts where they appear in the various Figures.
Figure 1 represents the back portion of the going part or sley beam of a loom,
with my improvements added thereto. Figure 2 is a transverse section through
line A B shewing the reed, fast, also, the breast beam of the loom, and Figure 3 is
a similar view shewing the reed loose: these are drawn to an enlarged scale.
The letter C indicates the going part or sley beam to which the reed D is
mounted extending the entire length of reed is plate E, which is attached to
the levers F the latter being secured to the rod G mounted to the underside of
going part C.
When the going part C is travelling in the direction of the arrow, and imme-
diately before the weft is "beat up," the end of catch rods H come in contact with
the brackets or springs J that are secured to the breast beam K, thereby raising
the end of catch rods H until the gib end at H³ is above the opening through the
plate L, thus locking the plate E, and reed D in the position as shewn by Figure 2,
until the return of the same, when the catch rods will lower to the bottom of hole
through plate L leaving the gib-end H¹ clear of the said plate.
"
When the shuttle from any cause fails to travel through the "shed" the catch
rods H laying at the bottom of the holes through plates L are free to be drawn
into the position as shewn by Figure 3; by, the shuttle being compressed between
the warp and the reed, thus by the reed and attachments being mounted in the
manner described, the former is moved into the position shewn in the case of a
"trap" and is fast during the beat up, thus giving a fast and loose reed alternately
when required.
What I claim as my invention is
'The catch rods H connected to plate E arranged substantially in the manner and
for the purpose as hereinbefore described and as illustrated by the accompanying
drawings.
