PROVISIONAL SPECIFICATION.
Improvements in or relating to Shuttles for Weaving.
1, JOHN MORTIMER, of The Neville Works, Elland Road, Leeds, in the County
of York, Shuttle Maker, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to improvements in shuttles such as are used for weaving
Woollen, Worsted, Linen, Cotton, and other goods, and its object is to construct the
shuttle so as to make it more durable by arming its bottom (side) edges with a strip
of wood or metal that can be easily replaced on becoming worn or damaged.
Hitherto various means have been employed for attaining this object, such as
inserting a number of Lignum-Vitæ plugs in the bottom of the shuttle at or near the
ends to prevent it wearing.
Now according to this invention I cut away a portion of the bottom of the shuttle
so as to form two long recesses or rabbets (one on each side) of suitable width and
depth extending nearly the full length of the shuttle parallel or otherwise with its
back and front sides or edges, that is to say, a longitudinal recess or rabbet cut or
formed at each side of the bottom from the outer edges inwards so as to leave the
central portion of the shuttle bottom intact. Each recess or rabbet is filled (and fixed
by any suitable means) with a strip or piece of wood (preferably, though not
necessarily so, harder than that of which the body of the shuttle is made) or
metal which is afterwards worked into shape to complete the outer contour of the
shuttle:
By constructing and arming the outer bottom (side) edges as above described I am
enabled readily to repair the shuttle should the said edges become damaged instead
of replacing it with a new one, and further shuttles thus made are much more durable
than those of ordinary construction.
The above described invention can be readily adapted to existing shuttles.
Dated this Twentieth day of April 1889.
COMPLETE SPECIFICATION.
Improvements in or relating to Shuttles for Weaving.
I, JOHN MORTIMER, of The Neville Works Elland Road, Leeds, 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 improvements in shuttles such as are used for weaving
Woollen, Worsted, Linen, Cotton, and other goods, and its object is to construct the
shuttle so as to make it more durable by arming its bottom (side) edges with a strip
of wood or metal that can be easily replaced on becoming worn or damaged.
Hitherto various means have been employed for attaining this object, such as
inserting a number of Lignum-Vitæ plugs in the bottom of the shuttle at or near
the ends to prevent its wearing.
In the drawings,
Fig. 1 is a side elevation and Fig. 2 a plan of inside of shuttle constructed
according to my invention. Fig. 3 a part plan of underside of shuttle with the
arming or wearing strips or pieces removed. Fig. 4. a part sectional elevation on

page_text: A is the bobbin pin, B, the guide cover, C, C the shuttle plates, and D D the
shuttle tips, all of which may be of ordinary construction.
Instead of making the body or casing E of the shuttle in one piece as is usual
I cut away a portion of the bottom or underside of the shuttle so as to form two
long recesses or rabbets F F (one on each side,) extending nearly the full length
of the shuttle respectively parallel (or otherwise) with its back and front edges or
sides. That is to say, in a shuttle of about eighteen or nineteen inches in length
by about two and a half inches in width and about two inches in depth, a longi-
tudinal recess or rabbet F of about say sixteen or seventeen inches in length, by
about three-fourths of an inch in width and about five-eighths of an inch in depth,
is cut or formed at each side of the bottom, from the outer edges inwards so as to
leave the central portion of the shuttle intact.
Each recess or rabbet F is filled (and fixed by any suitable means, such as screws or
pins GG) with a strip or wearing piece H of lignum-vitæ, or other wood preferably,
though not necessarily so, harder than that of which the body of the shuttle is made,
(or of metal) which is worked into shape to complete the inner and outer contour of
the shuttle as shown at Figs. 1, 2 and 4. When a metal strip employed it may be
made thinner, than the dimensions given in order to reduce the weight as much as
possible.
I would bave it understood that the dimensions herein given may be varied or
altered as circumstances require, and further that any parts of the shuttle not herein
described or illustrated may be of ordinary construction; also that the strip or
piece H may not, in some cases, be made to extend so far as is shown in the
drawings.
By constructing and arming the outer bottom (side) edges as above described I am
enabled readily to repair the shuttle should the said edges become damaged instead of
replacing it with a new one, and further shuttles thus made are much more durable
than those of ordinary construction.
The above described invention can be readily adapted to existing shuttles.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. An armature or protection for the bottom (side) edges of shuttles consisting of a
strip of hard wood or metal such as H fixed in a longitudinal recess or rabbett such as F
level with the shuttle bottom, by screws, pins or other convenient means substantially
as herein set forth.
2. In a shuttle for weaving purposes the combination of the strips or pieces of hard
wood or metal such as H with a shuttle body such as E having a longitudinal recess
or groove formed or cut along its bottom (side) edges for the reception of the said
strips or pieces as and for the purposes herein set forth.
