IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS FOR WEAVING
Year: 1880

page_text: LETTERS PATENT to Joseph Henry Pickles, of Burnley, in the County of
"
Lancaster, for an Invention of IMPROVEMENTS IN THE CONSTRUCTION
OF SHUTTLES USED IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said Joseph Henry Pickles at the
Office of the Commissioners of Patents on the 17th December 1880.
" IMPROVE-
JOSEPH HENRY PICKLES, of Burnley, in the County of Lancaster.
MENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS FOR WEAVING,"
This Invention relates principally to that part of the shuttle called the " tongue
or "peg," the object of the Invention being to give an increased steadiness thereto
and to prevent vibration.
"
This I effect by providing the " tongue" with a tail-piece, which, when the cop
is in its place, lies in a groove or recess formed in the underside of the shuttle for
that purpose, and as this tail-piece is the same width as the groove or recess, and
exactly fits it, vibration of the " tongue" is entirely prevented. I would here
observe that I prefer that the tail piece should be a continuation of the "tongue
beyond the "peg-pin," and that it should be slightly cranked in form, so as to lie
underneath the shuttle, but in some cases it may be so formed as to be bent back
or return in the direction of the "tongue" or peg, in which case it will lie in a
recess in the upper side of the shuttle. The groove or recess may be lined with
I propose to
metal if required. In combination with this improved "tongue
employ a spring fixed by means of a screw or rivet on the upper side of the
shuttle, and to have a small friction roller on the shoulder of the "tongue" acting
against the spring, but any other convenient form of spring may be used if
preferred; or instead of this spring I sometimes use a small catch for holding the
end of the tail-piece.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Joseph Henry Pickles in the Great Seal Patent Office on the
17th June 1881.
"IMPROV
JOSEPH HENRY PICKLES, of Burnley, in the County of Lancaster.
MENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS FOR WEAVING.".
This Invention relates principally to that part of the shuttle called the "tongue"
or "peg," the object of the Invention being to give an increased steadiness thereto,
and to prevent vibration.

page_text: This I effect by the means illustrated by the accompanying Drawings, in which
Fig. 1 is a view of the upper side of a shuttle made according to my Invention ;
Fig. 2 is a longitudinal section of the same; and Fig. 3 an underneath view.
""
I provide the " tongue a, a, of the shuttle b, b, with a tail piece c, c, which,
when the cop is in its place, lies in a groove or recess d, d, formed in the underside
of the shuttle for that purpose (see Figs. 2 and 3), and as this tail-piece c, c, is the
same width as the groove or recess d, d, and exactly fits it, all vibration of the
tongue" is entirely prevented.
16
The dotted lines in Fig. 2 show the position of the tongue and tail piece when
changing the cop.
I would here observe that I prefer that the tail piece c, c, should be a continuation
of the "tongue" beyond the "peg pin," as shown in the Drawing, and that it
should be slightly cranked in form so as to lie underneath the shuttle, but in some
cases it
may be so formed as to be bent back or return in the direction of the
tongue or peg, or to lie crosswise, in either of which cases it will lie in a recess
in the upper side of the shuttle.
"
The groove or recess d, d, may be lined with metal if required.
In combination with this improved " tongue I propose to employ a spring e, e,
fixed by means of a screw or rivet on the upper side of the shuttle, and to have a
small friction roller f, f, on the shoulder of the "tongue," but any other convenient
form of spring may be used if preferred; or instead of this spring I sometimes use
a small catch for holding the end of the tail piece. I prefer to make the shuttle
tip with a tube or socket g, g, (instead of a tang), and with projections h, h, of a
serrated form fitting between corresponding projections i, i, formed in the wood at
the end of the shuttle. The points of these projections (both wood and metal) are
slightly depressed, so as to lie lower than the edges of the corresponding notches
in which they fit, so that there are no sharp edges to catch against the threads.
The rounded end k, k, of the wood is split, and has a wedge l, l, placed within it,
which (when the tip is forced on) expands the wood and fixes the tip firmly in its
place.
I am aware that prior to my Invention a peg spring somewhat similar to the one
marked e, e, has been used on the upper side of a shuttle; I therefore do not claim
the use of such spring by itself, but what I do claim as my Invention and desire
to secure by Letters Patent is,-
"
1. The addition (to the tongue or peg of a shuttle) of a tail-piece fitting into a
recess, so as to keep the tongue steady and prevent vibration thereof, whether the
said tail piece be in the form of a continuation of the " tongue or peg" behind the
peg-pin," or bent back or returned in the direction of the tongue or peg, substan-
tially as hereinbefore described.
2. I claim the combination with such a tongue or peg (provided with a tail
piece) of a spring fixed by a screw or rivet on the upper side of the shuttle,
substantially as described.
In witness whereof, I, the said Joseph Henry Pickles, have hereunto set
my hand and seal, this Fifteenth day of June, in the year of our Lord
One thousand eight hundred and eighty one.
J. H. PICKLES. (L.S.)
