THOMAS HARDMAN, 904, Burnley Road, Portsmouth, near Todmorden, Journey.
man Shuttlemaker, do hereby declare the nature of this invention to be as
follows:-
:-
An improved loom shuttle, this relates to a new method of securing the usual
or any other suitable form of shuttle spring, which exerts the necessary presurre
at the line where it abuts on the shuttle peg head when in a working position
in the shuttle-body; also acting on the peg head as it turns on its pivot in the
shuttle when raised up to the perpendicular, or any other convenient inter-
mediate angle from the horizontal, working position of the shuttle peg for the
reception of the cop, tube, bobbin, or the like, the spring in all these varying
angles giving the requisite steadiness to the shuttle peg.
The improved loom shuttle consists in the application of a suitable metal eye-
bolt, with an aperture either square, round or any other convienient shape; for
the insertion, and retention, of the shuttle spring; in the usual indentation on
the top of the spring; or there may be indentations, on the top & bottom of the
spring to hold the spring rigid, when the eyebolt come into operation in the
indentation or indentations of the spring. The spring may be shaped to fit the
apertures of the eyebolt whether square or the like and of any convienient shape
for the line or portion where it abuts on the shuttle-peg head. The shank of
the eyebolt is screwed for the purpose of allowing the lock nut to turn either in a
tightening, or loosening direction. By bringing the combined eyebolt & shuttle
spring into the grooves the shank passing through a circular hole recessed on
the bottom of the shuttle, applying the locking washer, then the lock nut also
on the eyebolt shank turning the nut in a tightening direction draws the com-
bined eyebolt and spring, upon the line, or portion; of the shuttle peg head also
on a suitable part of the shuttle, and which pionts of contact, bring about with
tightening turns of the nut with a box key the requisite pressure on the spring
also acting on the line or portion of the shuttle peg head, with sufficient pressure
to retain it in a firm working position in the shuttle bedy.

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
-
This invention relates to an improved loom shuttle, and consists of an improved
means of applying tensional or spring pressure to the peg head, whereby the
latter, when in a working position in the shuttle body, is held quite firm and
secure free from any side shake, and the spring acts upon the peg head in such
a manner, that when the peg is raised from a horizontal to a vertical position,
or is brought to any other convenient intermediate angle, the spring, in any
of these positions, will give the necessary steadiness to the shuttle peg.
The invention consists essentially in the application of a suitable metal eve
bolt, having an aperture of any desired form, which aperture is intended for the
insertion and retension of the shuttle spring in the usual recess in the shuttle
body, and for firmly securing the same, so that it will act upon the peg head in
the manner indicated. The spring may be of any suitable form, but preferably
is bent or overlapped in the usual manner, and having a projecting portion,
which exerts pressure on the top of the peg head. The peg head is secured in
the shuttle body by the usual pin or pivot. The eye or loop of the bolt is slipped
over the bent end of the spring, and enters side grooves in the shuttle body.
whilst the shank of the eye bolt passes through a hole in the bottom of the
shuttle. A locking washer and nut are passed on the shank of the eye-bolt,
and tightened by means of a small box key inserted in a circular hole in the
bottom of the shuttle.
The spring is thereby firmly secured in position, and its projecting extremity
exerts the necessary pressure on the peg head at the top. The latter is formed
with a notch or recess at the top, into which the end of the spring enters, when the
shuttle peg is raised to a vertical position, thereby holding the shuttle peg rigid
in this position.
In the accompanying drawings,
í
Fig. 1 is a detached sectional side elevation of a loom shuttle with my improved
tensional devise attached.
Fig. 2 is a detached plan view of the bottom of the shuttle, and
Fig. illustrates the eye bolt and nut and washer heretofore described.
Referring to Fig. 1, A is the detached body of the shuttle, shewn in section
to illustrate the working parts. B is the peg head, and C its pivot. D is the
eve-bolt, which is pushed into grooves at each side of the shuttle body, and its
shank is screwed thereon, and passed through a hole in the shuttle body, emerg-
ing at the bottom into a circular hole or recess E.
This eye-bolt is employed for the purpose of holding firmly in position the
spring F, which is preferably of the usual shape as shewn, but it may take other
shapes. The bent portion G of the spring is pushed through the aperture of the
eye bolt, and the locking washer H is passed over the screwed extremity of the
eye-bolt, and the nut J tightened thereon, which has the effect of drawing the
eye-bolt down the grooves in the sides of the shuttle, and firmly securing the
spring Fin position. The projecting extremity of the spring F is thus cased
to exert pressurd on the top of the peg head B. whereby the latter is not only
held firmly in a horizontal position, but such is the case also when the peg
comes to be raised through any intermediate angle, and when finally it comes to
be raised vertically, the extremity of the spring F snaps into the recess K in
the peg head, locking, or rather, holding it in this position, ready for the recep-
tion of the cop, tube, or bobbin. or the like, the pressure of the spring, when
entering the recess, also assisting the upward movement of the peg.
Fig. 2 is a detached plan view of the bottom of the shuttle, in which is formed
the circular hole E, by which access can be had by the aid of a box key, for the
purpose of tightening the nut J against the face of the washer H (see Fig. 3).
Both nut and washer have serrated faces for security. The washer may also be

page_text: formed with a point or points or ridges M to enter the timber, when the nut is
tightened for additional security.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved construction of loom shuttles, substantially as described and
illustrated with reference to the accompanying drawings.
2. In a loom shuttle, the eye-bolt D for the retension of the bent portion G of
spring F, substantially as shewn and described for the purpose specified.
3. The combination, in a loom shuttle, of the eye-bolt D, nut J, washer H, peg
head B (of the shape shewn in Fig. 1 formed with recess K, and adapted in
the recess of the shuttle as shewn in Fig. 2) and also spring F. all the respec-
tive parts arranged and operating, substantially as described and illustrated.
