PROVISIONAL SPECIFICATION.
Improvements in Weaving Shuttles having Loose or Removable
Tongues.
We, JAMES WADDINGTON, of Little Horton, Bradford, in the County of York,
Shuttle Maker, EDWIN BOTTOMLEY, of Woodlands, Farsley, in said County,
Manager, JOSEPH JOHN GRIMSHAW, of Greeves Terrace, Farsley, aforesaid,
Loom Tuner, and IRWIN BROOK, of Kirkless House, Farsley, aforesaid, Designer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of weaving shuttle in which
the tongue or peg is removable to facilitate mounting the bobbin thereon such as
the arrangement described in Waddington's Specification No. 20772 dated the
20th December 1890. And the object of the invention is to provide a more secure
and durable device for locking the tongue in position.
For this purpose we mount the tongue in a pivoted spring head in the ordinary
way and provide a rest block having a longitudinal recess for the tongue to rest in.
This recess is made deeper than usual and has one or more projections on one or
both sides. The end of the tongue fitting the head has a notch or notches cut in it
to engage the said projection or projections and retain the tongue in position. The
said pivoted spring head is also cut with a similar notch or notches so that it may
also pass into the said recess.
.
When said projections are formed on each side of the said recess they are not
placed opposite each other so as not to unnecessarily weaken the spindle by forming
the notches thereon opposite each other.
By this arrangement the tongue is not free until it is raised fully to the position
required to remove the bobbin.

COMPLETE SPECIFICATION.
Improvements in Weaving Shuttles having Loose or Removable
Tongues.
We, JAMES WADDINGTON, of Little Horton, Bradford, in the County of York,
Shuttle Maker, EDWIN BOTTOMLEY, of Woodlands, Farsley, in said County,
Manager, JOSEPH JOHN GRIMSHAW, of Greeves Terrace, Farsley, aforesaid,
Loom Tuner, and IRWIN BROOK, of Kirkless House, Farsley, aforesaid, Designer,
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 that class of weaving shuttle in which
the tongue or peg is removable to facilitate mounting the bobbin thereon such as
the arrangement described in Waddington's Specification No. 20772 dated the
20th December 1890. And the object of the invention is to provide a more secure
and durable device for locking the tongue in position.
For this purpose we mount the tongue in a pivoted spring head in the ordinary
way and provide a rest block having a longitudinal recess for the tongue to rest in.
This recess is made as deep as the full thickness of the tongue and has one or more
projections on one or both sides. The end of the tongue fitting the head has a
notch or notches cut into it to engage the said projection or projections and retain
the tongue in position.

page_text: When said projections are formed on each side of the said recess they are not
placed opposite each other, so as not to unnecessarily weaken the spindle by forming
the notches thereon opposite each other.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a longitudinal section of one end of the shuttle with our
improvements applied thereto.
Figure 2, is a plan view of the same with the shuttle tongue removed and the
spring head raised to a vertical position to show the rest block beneath.
Figure 3, is a cross section of the same on the broken line a, b Figure 1. And
Figure 4, is a separate view of the notched end of the tongue.
Figure 5, is a similar view to Figure 2 representing a shuttle with notches on
both sides of the rest block and shuttle tongue.
Figure 6, is a separate side view of the spring head, rest block and the end of
the shuttle tongue in position. And Figure 7, is a plan view of the rest block alone.
The body A of the shuttle is of any ordinary construction and the spring head. B
is pivoted in the ordinary way thereto and is of usual form excepting that the
recess C enclosing the rest block D is somewhat larger than usual to allow a deeper
block to be employed.
In Figures 1 to 4 the notches E are only shown upon one side of the shuttle
peg P and corresponding projections F are formed on one side of the recess G in D
to engage such. notches. Owing to the depth this form of notch may be made
without weakening the shuttle tongue too much it is usually sufficient to form said
notches on one side only. But if desired the notches may be made on both sides
of the tongue and projections formed on each side of the recess G. In this case
the notches and projections are arranged as shown in Figures 5, 6 and 7 so that
those on one side are not opposite those on the other side and consequently the
tongue is not reduced in the same place on both sides..
Notwithstanding the size and durability of the notches and projections in either.
of the above arrangements the tongue is not seriously weakened as the full
thickness of the metal is left in the direction of the greatest strain. And owing to
the form of the notches and projections the tongue is not free until it is raised
considerably above the position shown in Figure 1, so that there is no possibility of
the tongue being detached in operation by the vibration of the spindle."
The spring head may be cut with somewhat similar notches to the tongue and
be arranged to more or less pass into the recess G but we find the additional cost
of construction to, generally speaking, exceed any practical advantage of such an
arrangement..

Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
In a weaving shuttle, a loose shuttle peg provided with a locking notch or locking
notches adapted to only engage a projection or projections on one side or sides of
the recess in the rest block or its equivalent, in combination with a rest block
having a side projection or projections adapted to engage said notch or notches,
substantially as herein shown and described and illustrated in the accompanying
drawings.
