PROVISIONAL SPECIFICATION.
Improvements in the Construction of Shuttles for Looms.
I, JAMES EDWARD CAMM of 6, Violet Street, Burnley, in the County of Lancaster,
Commission Agent, do hereby declare the nature of this invention to be as follows:-
:-
This Invention of Improvements embraces several new and additional devices,
whereby the durability of the shuttle is considerably increased, and less damage to the
warp and weft threads ensured, than with shuttles now in use.
The shuttle I prefer to make of "Mild Steel," which may be stamped or blocked
to shape by suitable dies. The weft is drawn in the usual manner through an eye in
the side of the shuttle, and to maintain the weft in its true position with the point of
the peg, it is caused to pass through a vertical V shaped slot, formed in front of
the pog.
To secure the peg in the shuttle stock, I form a rib on each side of the shuttle to fit
a groove on each side of the heel of the peg, so that when the said heel is pushed into
its socket immediately beyond the ribs, and the peg turned up out of its horizontal
position to remove a spent cop or bobbin, the peg will be prevented from coming out
of its socket; but the peg may be readily removed from the shuttle when the peg is
in its horizontal position, with the grooves of the heel of the peg parallel with the ribs
of the shuttle.
To retain and steady the peg, either in a horizonal or vertical position, a plug, acted
upon by a spiral spring or the like, is capable of adjusting itself to suitable indentations
in the heel of the peg; and to offer more or less resistance to the cop knocking off, the
end of the shuttle tongue is bent to form a nib near the heel of the peg for adjustment in
two or more holes, to ensure the desired expansion to the curve of the tongue for
securely holding the cop upon the peg.
I would here observe, that I do not confine myself to mild steel as a material for
my improved shuttle, as the same may be of wood, in which case, the tips may be
secured to the shuttle by nuts, or they may be pinned thereto.
Dated this 11th day of February 1889.

COMPLETE SPECIFICATION.
Improvements in the Construction of Shuttles for Looms.
I, JAMES EDWARD CAMM of 6, Violet Street, Burnley, in the County of Lancaster,
Commission Agent, 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 :—
In the provisional specification of this my said invention, I describe several devices
relating to the construction of shuttles, which I have since found to be wanting in
novelty. therefore disclaim such parts or devices, and do now confine myself solely
to the means or method of retaining and steadying the shuttle peg..
For this purpose, I employ a plug or sliding piece, acted upon by a spiral spring,
and capable of so adjusting itself in relation to the heel of the peg, as to effectually
retain and securely lock the peg, aud prevent its flying up and breaking the warp
threads, during the shuttle's traverse through the shed.
In using the plug, I form a hole or indentation at the extreme end of the heel or
the peg, into which the plug will insert itself when the peg is in a horizontal
position, such plug being withdrawn by the aid of a finger-piece when the peg is to
คา

the drawings.
Fig. 1 is a sectional elevation and Fig. 2 a plan of a shuttle constructed in accordance
with my invention. a, is a shuttlo peg, b, the heel of the peg, c, a slide piece, d, a
finger-piece, e, a projection from the slide, against which the spiral spring g abuts to
force the slide over the heel of the peg, which then becomes firmly locked between
the pins hand and the slide c, the latter of which is capable of moving in
grooves ff.
To raise the peg, the weaver withdraws the slide c from the heel by means of
finger-piece d.
Having now particularly described and ascertained the nature of my said invon-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
The means or method of retaining and steadying the shuttle peg, substantially as
described and illustrated.
Date this 16th day of November 1889.
