PROVISIONAL SPECIFICATION.
Improvement in or applicable to the Swell Springs of Looms
for Weaving.
We THOMAS WALSH of 85 Wrigley Street, Power Loom Overlooker, and
JOHN FREDERICK LOWE of 95 Wrigley Street, Mechanic, both of Oldham in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the spring which bears against the finger upon the stop
rod of certain looms for weaving, and which is known as the swell spring.
It is found that this swell spring, pressing against and rubbing across the surface
of the said finger, in time wears the finger and itself becomes worn; and not only
has the spring to be shortened or changed when worn, but sometimes it will stop the
loom when not required, owing to its imperfect action when the parts become too
much worn.
According to our invention we apply to the said spring, at the end which works
against the finger, a short strip of leather or other suitable material which will
act as a pad and prevent the spring and the finger from being worn as above
described. For this purpose we bend the free end of the spring back so as to form
a recess into which the end of the leather strip or similar pad can be slipped, and at
a suitable distance from the end of the spring we punch up one or more spikes, teeth,
or burrs, to project from the spring into the surface of the leather and keep it in
place, the leather or other pad being so thick as not to be loose in the aforesaid
recess. Thus the leather or other pad is readily affixed to the spring and can as
readily be removed and replaced if desired.
Other means may be adopted for attaching the pad to the spring.

manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to the spring which bears against the finger upon the stop
rod of certain looms for weaving, and which is known as the "swell spring."
It is found that this swell spring pressing against and rubbing across the surface
of the said finger, in time wears the finger and itself becomes worn; and not only
has the spring to be shortened or changed when worn, but sometimes it will stop
the loom when not required owing to its imperfect action when the parts become too

page_text: The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawing is a back view of part of the slay and shuttle box of a
power loom with our improvements shown as applied thereto, and Fig. 2 is a plan
view of the same.
Fig. 3 shows face and edge views on a larger scale of our improved swell spring
detached.
a is part of the lathe or slay and 6 the shuttle box c is the swell, d the stop rod
finger and e the swell spring.
According to our invention we apply to the said spring e at the end which works
against the finger, a short strip of leather or other suitable material which will act
as a pad and prevent the spring e and the finger & from becoming worn as above
described.
For this purpose we bend the free end et of the spring back (see Fig. 3) so as to
form a recess into which the end of the leather strip or similar pad f can be slipped,
and at a suitable distance from the end of the spring e we punch up one or more
spikes, teeth, or burrs g to project from the spring into the surface of the leather f
and hold it securely in its place, the leather or other pad being of such a thickness
as not to be loose in the aforesaid recess.
Thus the leather or other pad f is easily affixed to the spring e and can as readily
be removed and replaced if desired. Other equivalent means may be adopted for
attaching the pad to the spring.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
The application and combination with the free end of the swell spring of a loom
of a strip of leather or other suitable pad substantially in the manner and for the
purpose herein before set forth.
