PROVISIONAL SPECIFICATION.
Improvements in Weft Stop Fork Motions of Looms for Weaving.
We EDWARD DUERDEN of 99 Bastwell Terrace, Blackburn, in the County of
Lancaster, Manufacturer, and SAMUEL BROGDEN of 18 Lawrence Street,
Blackburn aforesaid, Overlooker, do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the weft stop fork motion of looms for
weaving, the object being to simplify, and reduce the number of parts so that there
is less liability of the fork being damaged, or knocked out of shape, and less friction
is put on the weft.
According to this invention we dispense with the ordinary fork grate and fix in
its place, and to the slay a hinge carrying a finger held in a vertical position by
means of a small blade spring. The weft fork has only two prongs and at the beat
up of the slay one prong passes on each side of the hinged finger across the front of
which the weft is shot. The fork is operated in the ordinary manner but having
only two prongs these can be made so as to pass quite clear of the hinged finger,
but if the latter is accidentally struck or knocked, and comes in contact with the
hinged finger the latter turns on its hinge and no damage is done.

COMPLETE SPECIFICATION.
Improvements in Weft Stop Fork Motions of Looms for Weaving.
We EDWARD DUERDEN of 99 Bastwell Terrace, Blackburn, in the County of
Lancaster, Manufacturer, and SAMUEL BROGDEN, of 18 Lawrence Street,
Blackburn, aforesaid, Overlooker, 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 :---
This invention relates to improvements in the weft stop fork motion of looms for
weaving, the object being to simplify, and reduce the number of parts so that there
is less liability of the fork being damaged, or knocked out of shape, less friction is
put on the weft and there is less liability of the loom weaving without weft than
heretofore.
Such being the nature and object of the said invention the following is a
complete description of same reference being had to the accompanying drawings in
which:-
Fig. 1 is a side elevation of the improved appliances connected with the weft
stop fork motion of looms.
Fig. 2 is a front or end view of Fig. 1.
According to this invention we dispense with the ordinary fork grate, and fix in
the place of the weft fork grate a hinge 1 which is screwed onto the slay 2.
The hinge carries a finger 3 held in a vertical position by means of the small
blade spring 4.
The weft fork 5 has only two prongs 6. 6. and at the beat up of
the slay the vertical finger 3 passes between the two prongs 6. 6, one prong passing
on each side of the hinged finger 3 across the front of which the weft is shot, and
passes in the usual way.
The fork is operated, and operates in the ordinary manner, but having only two

page_text: prongs to pass, one on each side of one vertical finger there is less liability of the
parts coming in contact, and thus less liability of the loom weaving without weft,
than was heretofore the case, as for instance when three prongs of a fork passed
between the four bars, and under the top of the fork grate and where a very slight
bending of one, or more of the prongs or bars would cause damage and even
breakage of the parts, and the lo m to weave without weft.
In the event of one of the two prongs or other parts coming into contact with the
vertical finger, the latter will give way, turning on its hinge 1 and lying flat on the
surface of the slay, the fork will not be operated upon by the weft, and the loom
will at once stop, and thus no damage is done. The finger 3 is moved to its correct
position, as shewn in the drawings, by hand.
Having now particularly described and ascertained the nature and object of the
said invention, and in what manner the same is to be employed, we declare that what
we claim is:
-
The vertical hinged linger 3 in combination with a two pronged weft fork as
and for the purpose herein fully described, and substantially as illustrated by the
annexed drawings.
