PROVISIONAL SPECIFICATION.
Improvements in Tongue Rests for Loom Shuttles.
JAMES WADDINGTON Holme Top Mills Little Horton Bradford in the
County of York Shuttle Maker do hereby declare the nature of this invention to
be as follows:-
In loom shuttles hitherto in use the tongues (upon which the spools are mounted)
after having become a little worn frequently cause breakages of weft (especially
with full spools) by the tongues vibrating sideways causing the spools to press
against the insides of the shuttles thus operating against the free delivery of the
weft thereby causing frequent breakages of the same.
The object of my invention is to prevent the tongues from vibrating sideways
even after they have become partially worn.
This I accomplish by constructing a metal tongue rest having a V grove or
channel along its upper face and also in constructing that part of the tongue head
which bears on the said metal rest of a V shape so as to exactly fit into the
said V grove or channel of the metal tongue rest. By these means the tongues
are firmly held down in working position and effectually prevented from vibrating
sideways when pressed on to the metal rests by the action of the holding down springs.
The said V parts of the tongue heads and metal rests offers a large wearing surface
operating against the tongues wearing down and becoming too low. The metal
rest I firmly secure in the shuttles by a rivett passing transversely through both
the shuttle and rest.
The mounting of the tongues and springs in the shuttles I accomplish in the
usual manner.
The position of the said ✓ parts of the metal rest and tongue head may be
reversed without departing from the object of my invention, that is to say
the V grove or channel may be formed in the tongue head the corresponding or
raised portion of the V being formed along the upper face of the said metal rest.

COMPLETE SPECIFICATION.
Improvements in Tongue Rests for Loom Shuttles.
I, JAMES WADDINGTON, of Holme Top Mills, Little Horton, Bradford, in the
County of York, Shuttle Maker, 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 has for its object, the construction of shuttle rests and tongues
therefor in such a manner, that the tongues when placed in their working position.
are prevented vibrating, or moving sideways in the shuttle, and thus to minimise
the breakages of the weft during the operation of weaving.
The tongues of loom shuttles as hitherto supported, after being in use for
some time frequently cause breakages of the weft, when the spool or tube on the
shuttle tongue is full, by reason of the tongue moving sideways, and thereby
causing the weft to press against the inside of the shuttle, thus preventing the free
delivery of the weft, and thereby causing breakages.
In describing my invention in detail, reference is made to the accompanying
drawings in which
Fig. 1 represents a view of a shuttle with a portion cut away in order to more
clearly show the shuttle tongue and rest therefor.

page_text: Fig. 2 18 a section through line a. b. and,
Figs. 3 and 4 are sectional modifications.
The tongue A. is mounted in the shuttle block B. on pin C. and the spring D.
applied in the usual manner to which no claim is made as forming part of this
invention.
Below the shuttle tongue head A' I mount a metallic rest E. and secure
same to the shuttle block by a rivet passing transversly through both shuttle
block and rest; the upper surface of which is prepared with a groove or
channel, into which fits the raised portion on the underside of the shuttle tongue
head A held therein in the working position by the spring D. thereby effectually
preventing the tongue A moving sideways, and the weft on the spool or tube
pressing against the inside of the shuttle, by which the free delivery of the weft is
prevented, thereby causing the latter to break.
A modification of my improvement is shown in Fig. 3, where the groove or
channel is reversed, being formed in the shuttle tongue head A' and the corre-
sponding raised portion on the metallic rest E. so that when the shuttle tongue is
in the working position, it is retained by the engagement of the raised portion with
the groove in the manner as before described.
Another modification is shown by Fig. 4, where the groove or channel in the
metallic rest E. and the raised portion on the shuttle tongue head A' are curved,
by which arrangement the shuttle tongues may be retained, so that when worn
slack, the weft on the spool or tube does not press against the inside of the shuttle,
and thus prevent the free delivery of the weft.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a loom shuttle, the rest E. provided with a groove or channel for the
reception of a raised portion on the shuttle tongue head, arranged substantially in
the manner and for the purpose as herein before set forth.
2. In a loom shuttle, the tongue head provided with a groove or channel for the
reception of a raised portion on the rest E arranged substantially as hereinbefore
Bet forth.
