Improvements in Tongue Rests for Loom Shuttles.
I JAMES WADDINGTON Holme Top Mills Little Horton Bradford in the County
of York Shuttle Maker do hereby declare the nature of this invention to he as
follow-:-
:-
That is to say that my invention relates to winow
employed in weavers loom shuttles-and has for its object the construction and
arrangement of a moveable and adjustable rest that may be easily raised or adjusted
in height when the tongue becomes too low consequent on excessive wear or other
catise. To effect my said object I construct a metal tongue rest similar in width to
the tongue head and made flat on the upper and under side the upper side holding
up and supporting the tongue head in opposition to the pressure of the holding
down spring. The under side re-ting on a corresponding fat projection formed in
the bottom part of the shuttle and made so as to receive small strips of card board
or other packing for adjusting or raising the inetal tongue rest and thereby
the tongue.
At one end of the metal tongue rest I construct an eye for the reception of a pin
which passes transversely through both the shuttle and the eye of the metal tongue
rest thus securing the latter in its proper place in the shuttle.
At the other end and on the under side of the metal tongue rest provide a lip
extending a little below the upper face of the said flat projection formed in the
bottom of the shuttle. This lip prevents the adjusting strips of card board from
moving out of their place until the metal tongue rest is raised up.
To adjust the height of the tongue when it becomes too low consequent on
exce-sive wear or other cause it is only necessary to raise it clear of the metal rest
and then raise the lip end of the rest sufficient to receive small pieces of card board
or other material betwixt the projection formed in the shuttle and the underside
of the metal rest. After the card board is inserted it is only necessary to press
down the rest to its proper position when the lip of the rest will effectually prevent
the card board packing from moving out of its place.
It is a well known fact amongst weavers that shuttle tongues wear down very
rapidly involving constant trouble and cost-and it will be readily seen that my
invention provides a most simple and effective means of adjusting the height of the
tongue rest and thereby the tongue.

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 relates to what is known as the tongue rest employed in weavers'
loom shuttles, and has for its object, the construction and arrangement of the same,
so that it is movable and may be adjusted whenever required in consequence of the
end of the shuttle tongue getting too low and thereby interfering with the free
delivery of the weft.
In describing my invention in detail, reference is made to the accompanying sheet

page_text: of drawings in which Fig. 1. represents a view of a shuttle partly in section and
provided with a tongue rest, constructed in accordance with my invention.
The shuttle block A is constructed for the most part in the ordinary manner and
the tongue B. along with spring C. are also of the ordinary construction mounted
in the usual manner.
In the shuttle block under the square portion of the tongue head at BI form
the upper surface of support D. flat and parallel with a centre line running from
centre of tip E. to centre of tip of the shuttle, and between the said surface and
tongue, I insert a movable rest plate . of a width equal to the width of the tongue
head 13 the rest plate being provided with an eye through which a pin G. passes
supported by the shuttle block thereby holding the rest plate in its required position,
the opposite end at F being bent downwards below the upper surface of D. for the
purpose as hereinafter described.
As is well known to persons conversant with weaving, after a short time, the
end of the shuttle tongue at B2 begins to descend below the centre of the eye at H.
when the free delivery of the weft is interrupted.
In order to adjust the shuttle tongue B. to its required position whenever the end
gets too low to admit of the free delivery of the yarn, the tongue rest plate F. is
raised by the lip at F and one or more pieces of paper or card board inserted in
the space shown by thick black line between the underside of rest plate F. and
upper surface of D. which as will be well understood, when the rest plate F. is
put back to the position shown, will elevate the end of tongue end at B the lip F
on one end and the angular portion at the other end of the rest plate preventing the
paper or cardboard packing moving out of its place, thus by these means enabling
the attendant to adjust and keep the tongue B. in the position for effecting a free
delivery of weft.
My object may also be accomplished by constructing the rest plate F. without
an eye for the reception of pin G. for securing same to the shuttle block, by bending
the rest plate at both ends as shown by Fig. 2. in which case the rest plate may be
removed entirely from the shuttle block to allow of the insertion of paper or other
packing between the underside of rest plate F. and top of support D. the lips F
at the ends preventing the packing leaving its position, and the tongue elevated to
the required height.
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 :-
A shuttle block combined with a rest plate F. and shuttle tongue B. in such a
manner that the rest plate F. is adjustable substantially in the manner and for the
purpose as herein before set forth.
Dated this 1st day of July 1891.
