PROVISIONAL SPECIFICATION.
Improvements in the Means for Securing the Wheels or Pulleys to
Shuttles Employed in Looms for Weaving.
I, JOSEPH WILSON, of 42 Beaumont Street, Purwell Estate, Batley, Yorkshire,
Shuttle Maker, do hereby declare the nature of this invention to be as follows :—
This invention has reference to shuttles employed in broad looms, and consists in
the means for securing the wheels or pulleys thereto.
In order to carry out my invention I mount the wheels or pulleys loosely on a
metal axle and secure them to such axle by means of square or other angular nuts,
which project from the face of the wheels or pulleys. Openings are formed in the
bottom or solid part of the shuttle, one at each end, to admit the wheels or pulleys,
and at each side of the said openings, transversely to the shuttle, are formed suitable
grooves or recesses into which the nuts enter when the wheels or pulleys are placed
into the openings in the shuttle; the said grooves or recesses supporting the axles,
and serving as bearings therefor. The axles and wheels are now firmly secured in
the shuttle by means of screws, which are screwed through the shuttle and through
screw threaded holes formed in the centre of each axle.
By the means above described, wheels or pulleys are secured to the shuttle in much
less time than it takes at present; whilst the metal plates and bearings now employed
are dispensed with, and the cost reduced, in addition to which there is no liability of
the wheels shaking loose by the action of the pickers striking the shuttle.

COMPLETE SPECIFICATION.
Improvements in the Means for Securing the Wheels or Pulleys to
Shuttles Employed in Looms for Weaving.
I, JOSEPH WILSON, of 42 Beaumont Street, Purwell Estate, Batley, Yorkshire,
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 reference to shuttles employed in broad looms and consists in
the means for securing the wheels or pulleys thereto.
In order to carry out my invention I mount the wheels or pulleys loosely on a
metal axle and secure them to such axle by means of square or other angular nuts,
which project from the face of the wheels or pulleys. Openings are formed in the
bottom or solid part of the shuttle, one at each end to admit the wheels or pullies, and
at each side of the said openings, transversely to the shuttle, are formed suitable
grooves or recesses into which the nuts enter when the wheels or pulleys are placed
into the openings in the shuttle; the said grooves or recesses supporting the axles,
and serving as bearings therefor. The axles and wheels are now firmly secured in the
shuttle by means of screws, which are screwed through the shuttle and through screw
threaded holes formed in the centre of each axle.
In order that my invention may be more fully understood, I herein make reference
to the accompanying sheet of drawings wherein Fig. 1 is side elevation of one end of
a shuttle, partly in section, shewing my improvements applied thereto; Fig. 2 is
plan view of the underside of said shuttle, and Fig. 3 is cross section taken through
line 1-2 in Fig. 2. a is the body or solid part of the shuttle in which I form
chambers or openings b for the reception of the wheels c, other like openings being

page_text: formed at the opposite end of said shuttle for the same purpose; and at each side of
the opening b, transversely of the shuttle, are grooves or recesses d. The wheels or
pulleys c are mounted loosely on the axle e, the central portion e¹ of which is enlarged
and preferably made angular, and has a screw-threaded hole e² formed in the centre
thereof. The bosses of the wheels cabut against the faces of the enlarged portion e
of the axle, which prevent lateral movement of the wheels in one direction, whilst the
nuts f screwed onto the ends of the axles prevent lateral movement in the opposite
direction, and secure the wheels on their axle. A hole or socket g is bored through
the shuttle, terminating in the opening b, to admit insertion of the screw /. When
the wheels are placed in the opening the nuts fenter the recesses d, so that when the
screw is passed through the hole g and screwed into the screw threaded hole e¹ in
the axle, it causes the nuts f to be drawn tightly against the upper faces of the
recesses d whereby they support and form bearings for the axle. The head of the
screw when it is screwed home enters a corresponding recess in the surface of
the shuttle as shewn in the Drawings.
By the means above described, wheels or pulleys are secured to the shuttle in much
less time than it takes at present, whilst the metal plates and bearings now employed
are dispensed with, and the cost reduced, in addition to which there is no liability of
the wheels shaking loose by the action of the pickers striking the shuttle.
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
The means and method herein shewn and described for securing wheels or pulleys"
to shuttles employed in broad loonis.
