PROVISIONAL SPECIFICATION.
Improvements in Shuttles for Weaving Looms.
I, JOE STEAD, of 112, Thornton Road, Bradford 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 that class of heavy shuttles which are
mounted on shuttle wheels. Said wheels are commonly made of wood hooped with
metal and having a metal arbor mounted between centres, which leaves them
liable to be affected by damp or changes in the atmosphere, and the object of my
invention is to obviate this defect.
For this purpose I employ a metal roller reduced in diameter in the middle and
recessed on each outer face to reduce the weight, and loosely mounted on a fixed
arbor which may be slightly reduced in the middle to facilitate lubrication.
Metal eyes are fixed in the shuttle to receive the ends of said arbor one of which
is formed with a screw thread to retain the pin in position, but the other end rests
in the eye without being confined longitudinally so as to allow of free expansion
or contraction of the shuttle.

Improvements in Shuttles for Weaving Looms.
I, JOE STEAD, of 112 Thornton Road, 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 improvements in that class of heavy shuttles, which
are mounted on shuttle wheels, the latter being commonly made of wood hooped
with metal and having a metal arbor mounted between centres. The shuttles being
made of wood are liable to be affected by damp or changes in the atmosphere,
which affects the mounting of the wheels, the object of my invention being to
obviate this defect.
In explaining my invention in detail
Fig. 1. represents a side elevation of a shuttle provided with wheels mounted in
accordance with my invention.
Fig. 2. is a view of the underside of a shuttle.
Figs. 3. 4. are views of a pair of wheels.
Fig. 5. an end view of one of the journals for supporting the wheels, and
Fig. 6. a view of the arbor supported at each end by a journal block shown in
section.
Near to each end of the shuttle block A. are mounted in the usual recesses B. B.
the wheels C. C. which by preference are made of metal reduced in diameter
between them at C and loosely mounted on a fixed arbor D. secured in such a
manner as to allow of the free expansion and contraction of the shuttle block A.
and slightly reduced in diameter in the centre at D' thereby forming a recess to
facilitate lubrication.
The arbors D. are supported by the journal blocks E. and E' recessed into and
secured to the shuttle block A. each arbor passing freely through one journal
block E. and a pair of wheels C. is secured in its required position, by the end

page_text: screwing into the respective journal block E' at the opposite side of the shuttle.
The other end of each arbor, not having a thread thereon is free in its supporting
journal block E. and therefore allows the wood of the shuttle to expand or contract
in accordance with the humidity of the atmosphere, without in any way affecting
the mounting of the wheels..
Having now particularly described and, ascertained the nature of this inven-
tion, and in what manner the same may be performed, I declare that what I
-claim is :-
A weaving shuttle in which are combined the wheels C. with an arbor D.
mounted in journal blocks E. and E the arbor being secured by the block E. and
all the parts arranged substantially in the manner as shown and hereinbefore
'described and for the purpose set forth.
