Year: 1879

page_text: LETTERS PATENT to James Lang, of Preston, in the County of Lancaster,
William Stancliffe, of the same Place, and John Brierley, likewise of. the
same Place, for the Invention of "IMPROVED SWELL PIN HINGE JOINT FOR
LOOMS."
PROVISIONAL SPECIFICATION left by the said James Lang, William Stancliffe,
and John Brierley at the Office of the Commissioners of Patents on the 26th
March 1879..
JAMES LANG, of Preston, in the County of Lancaster, WILLIAM STANCLIFFE, of
the same Place, and JOHN BRIERLEY, likewise of the same Place. "IMPROVED
SWELL PIN HINGE JOINT FOR LOOMS."
The ordinary method of securing the swell piece in the back plate of shuttle box
is by cutting out a space in such plate for the swell piece to fit in; then to bore a
small hole from the top edge of such plate, and fix a wire through the wood and
customary eye at the outer end of such swell piece into the wood underneath, thus
forming a wood and iron joint. The great evils attending such methods are :-
The pin going through to form such joint is of necessity small, and, however
hard the metal, it is very quickly worn out and break, this necessitates taking out
the back board to get out the broken pieces and replace with new; the eye hole at
the end of swell piece soon becomes oval, being small, and necessarily a new one is .
required; serious accidents likewise often occur from the flying out of shuttles when
a breakage takes place.
Our Invention overcomes all these evils. Instead of forming a joint as before
stated, we shape our swell piece end so as to form the male part of an ordinary
shaped hinge, with the exception that the hinge pin is made very much larger than
those of the ordinary kind. The female portion of such hinge we make to bolt on
the outside of the back plate of the shuttle box, the hinge roll being fitted into the
back-plate; the hinge pin may or not be secured by a small set pin. Thus made
the whole may be taken out and replaced in three minutes without disturbing the
back board of the shuttle box, and will wear as long as the loom.

SWELL PIN HINGE JOINT FOR LOOMS."
Fig. 1 is a front elevation of the ordinary back board of the shuttle box of a loom
with fast reed.
Fig. 2, a plan of the same.
Figs. 3 and 4 are similar views of a loose reed loom.
A, A, on Figs. 1, 2, 3, and 4 represents the ordinary back board of the shuttle
box of a loom; B, B, the swell piece fitted into such back boards; C, C, a hinge piece
fitted to the outer end of such swell piece; D, D, bolt for securing such hinge to
the back board; E, E, a set pin for securing the hinge pin F, F.
.
The ordinary method of securing the swell piece is by making a sort of hinge
between the end of the swell piece and the back board, passing a small pin from
the top edge of the back board through a hole provided in the outer end of such
swell piece, and thence again into the wood, thus forming a joint of wood and iron.
The più so passing must of necessity be very small, as the back board is only
five eights of an inch thick. This small pin is very soon worn through and breaks,
often splitting the back board. The shuttle flying out causes serious accidents both
to weaver and yarn. The back board has always to be taken out to get out the
broken pieces in order to replace with new.
Our Invention, as will be seen by the before mentioned Drawings, overcome all
these evils, as instead of forming a joint of wood and metal we make an inde-
pendant hinge of metal with a large pin in it, which we bolt to the back board, and
which may be replaced when required in a few moments without disturbing the
back board; and should one side of the hinge pin becomes worn by means of the set
pin E, it may be turned a little round, set, screwed up again, and be as firm as when
new.
Having now fully described our Invention and its advantages, we desire it to be
understood that we do not confine ourselves to the precise details shown and
described, but what we claim as secured to us herein is,-
The several parts combined to form a swell pin hinge joint independantly, con-
structed as and for the purposes hereinbefore described.
In witness whereof, we, the said James Lang, William Stancliffe, and John
Brierley, have hereunto set our hands and seals, this Fifteenth day of
September, in the year of our Lord One thousand eight hundred and seventy
