IMPROVE- MENTS IN SHUTTLES FOR WEAVING PURPOSES
Year: 1877

page_text: LETTERS PATENT to James France Gomersall and Thomas Copley, both of
Morley, near Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN SHUTTLES FOR WEAVING PURPOSES."
PROVISIONAL SPECIFICATION left by the said James France Gomersall
and Thomas Copley at the Office of the Commissioners of Patents on the
27th October 1877.
JAMES FRANCE GOMERSALL and THOMAS COPLEY, both of Morley, near Leeds, in
the County of York. "IMPROVEMENTS IN SHUTTLES FOR WEAVING PURPOSES."
Our Invention has reference to the ordinary wooden shuttles, and is to supply
bearings for the runners instead of those ordinarily used; by the application of the
old bearings the shuttle is much weakened and rendered very liable to breakage.
For this purpose we fix within the shuttles, and at each end, a pair of metal plates,
in which may be fitted bushes for the reception of the ends of the runner pins. Or
the plate itself is so constructed as to form the bush or bearing for the ends of the
runner pins. These plates are so arranged that fresh bushes may be readily fitted
thereto, without any damage to or weakening of the shuttle. By this arrangement
the shuttle runs when working much more readily, is much more easily repaired, and
is less subject to breakage.

Patent Office on the 27th April 1878.
JAMES FRANCE GOMERSALL and. THOMAS COPLEY, both of Morley, near Leeds, in
the County of York. "IMPROVEMENTS IN SHUTTLES FOR WEAVING PURPOSES."
This Invention relates to shuttles employed in looms for weaving in which
runners are fixed, and our improvements consist in the use of metal bearings for the
said runners, by means of which we are enabled to dispense with the screws and
plates hitherto fixed in or on the sides of shuttles, and which from the imperfect
manner of fixing have been a source of loss, arising from damaged pieces, bulged
stays, and broken shuttles.
The metal bearings which we employ are let in to the under side of the shuttle,
and fastened therein by means of screws. In the centre of the bearing is a boss or
enlargement of the casting for receiving the axle of the runner, and this boss may
be cast on the bearing itself, or it may be formed on a separate slip of metal, so
shaped as to slide in a groove in the bearing and capable of adjustment, or of being
removed and replaced by a new one when the neck becomes loose through continued
wear of the parts.
In order that this Invention may be more fully understood, we herein give
reference to the accompanying Sheet of Drawings, of which Fig. 1 shews the con-
struction of the under side of the shuttle; Fig. 2 a side view of same; Fig. 3 a
cross section; and Figs. 4, 5, and 6, details of our improved bearings.
.
A are the bearings which are let into the shuttle on the under side, and fastened
therein by screws B. These bearings have a collar or boss C, which may either be
formed on the bearing as in Fig. 4, or may be formed in a separate casting, as shewn
in Fig. 6, and slid in a dovetail groove D provided therefor, as shewn in Fig. 5.
These bosses receive the axes of the runners E, and as will be readily seen they are
perfectly free from all liability to become loose during the working of the shuttle,
and if at any time the bearings should wear away round the axes, they may be
renewed either entirely or partially by adopting the form of bearing shewn in Figs. 5
and 6.
By the use of our Invention old shuttles which have been rendered useless by
wear or breakage about the runners, may be rendered serviceable, whilst by
applying it to new shuttles it will be found that the durability thereof is greatly
increased.
Having thus described the nature of our Invention, and the manner in which the
same is to be or may be performed we would have it understood that we do not
confine ourselves to the particular form of bearing shewn, or composition of metal
used; but what we claim and consider to be new is, the employment of runner
bearings inserted within the shuttle, substantially as and for the purpose herein
shewn and described:
In witness whereof, we, the said James France Gomersall and Thomas
Copley, have hereunto set our hands and seals, this Eleventh day of April,
in the year of our Lord One thousand eight hundred and seventy-eight.
Signed, sealed, and delivered by
the within-named James France
Gomersall and Thomas Copley,
in the presence of
JAMES FRANCE GOMERSALL. (L.S.).
