IMPROVEMENTS IN APPA- RATUS APPLICABLE TO LOOM'S FOR WEAVING
Year: 1859

page_text: LETTERS PATENT to William Dawson, of Blackburn, in the County of
Lancaster, Shuttle Maker, and Thomas 'Singleton, of Over Darwen, in
the said County, Weaver, for the Invention of "IMPROVEMENTS IN APPA-
"
PROVISIONAL SPECIFICATION left by the said William Dawson and
Thomas Singleton at the Office of the Commissioners of Patents, with
their Petition, on the 8th October 1859.
We, WILLIAM DAWSON, of Blackburn, in the County of Lancaster, Shuttle
Maker, and THOMAS Singleton, of Over Darwen, in the said County, Weaver,
do hereby declare. the nature of the said Invention for "IMPROVEMENTS IN APPA-
RATUS APPLICABLE TO LOOM'S FOR WEAVING" to be as follows:-
To keep the shuttle peg in its proper position we fix on the pin a piece of
metal with four or more sides or surfaces to form the peg bearing, each surface
having a different' incline, so that when one side is worn so far as to cause the
peg to sink out of its proper position, by turning the said bearing to another
inclined surface the shuttle peg-will be restored to its proper position without
taking the pin out. Or we screw a small headed bolt into the peg, so that
when the pin becomes worn we can regulate the position by adjusting the
head of the bolt to any required projection, and thus keep the peg right.

page_text: When weaving with gold thread we put on the shuttle peg behind the bobbin
a conical tube made of elastic material, so that one end of it will fit the peg,
and the other the end of the bobbin by which the gold thread is prevented
getting off the bobbin and breaking, thus preventing waste. Instead of the
round spindle for the picker to work on we make it square and place metal
bushes in the picker to fit the square spindle, and where the picker strikes the
shuttle we make a hole through it with a thread in the hole, so that by placing
a piece of caoutchouc or other elastic material to strike against the shuttle,
the interior thread will keep it firm in its place, and if desirable, we fix a
spring in the back part of the picker pressing against the elastic material to
resist the blow. To avoid the difficulty of keeping the cop firmly on the
shuttle peg we make a frame with a number of tubes on the surface, the
said frame fitting a vessel containing water, so that when a cop does not easily
fit the peg, instead of wetting the peg in the mouth, the weaver puts the cop
into one of the said tubes, and the end of the cop is immersed in the water,
which answers the desired purpose. We also use an additional check strap
to act against the back part of the picker to relievo the shock of the blow.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Dawson and Thomas Singleton in the Great Seal
Patent Office on the 7th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
DAWSON, of Blackburn, in the County of Lancaster, Shuttle Maker, and
THOMAS SINGLETON, of Over Darwen, in the said County, Weaver, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of October, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-third year of Her reign,

William Dawson and Thomas Singleton, Her special licence that we, the
said William Dawson and Thomas Singleton, our executors, administrators,
and assigns, or such others as we, the said William Dawson and Thomas
Singleton, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-

page_text: PROVEMENTS IN APPARATUS APPLICABLE TO LOOMS FOR WEAVING," upon the con-
dition (amongst others) that we, the said William Dawson and Thomas
Singleton, by an instrument in writing under our hands and seals, or under
the hand and seal of one of us, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
to be
NOW KNOW YE, that we, the said William Dawson and Thomas Single-
ton, do hereby declare the nature of our said Invention, and the manner in
which the same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say):-
Our Invention consists, firstly, in improved arrangements of the bearing
surface of the shuttle peg in order to maintain it in its proper position;
secondly, in the application of a conical elastic tube to the shuttle peg when
weaving with gold thread; thirdly, in improvements connected with metal
pickers; fourthly, in the employment of a tubular frame in a vessel containing
water for wetting the ends of the cops; and, fifthly, in the use of an additional
check strap.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings. In Fig. 1 we represent
an adjustable peg bearing surface for keeping the shuttle peg in its proper
position. Upon the pin a is placed a piece of metal b with four sides, each
side being a different distance from the centre of the pin, so that when one
side is worn so far as to cause the shuttle peg c to sink out of its proper
position, if the piece of metal is turned to another side forming a higher
bearing surface the shuttle peg will be restored to the position required
without taking the pin out, but a square pin may be used instead of a round
one, in which case it must be removed in order to turn the piece of metal, and
instead of four sides any other suitable number may be employed. In Fig. 2
we shew the employment of the head of a screw for adjusting the exact
position of the shuttle peg. Into the end of the peg c we place the screw d,
the head of which rests upon the pin a, and as the pin wears, the screw is
lowered to make up the deficiency, and thereby regulate the position of the peg.
In Fig. 3 we shew the application of a slotted piece of metal having two sides
of different widths for adjusting the position of the shuttle peg. The piece of
metal is shewn at e, resting on two pins f, the thin side of the metal being at
the top, and the thick side at the bottom, and when the metal has worn so that
the peg is too much depressed, the pins are taken out and the piece of metal

page_text: reversed, thereby raising the peg to its right position. In Fig. 4 we represent
the employment of two pins g, for the end of the peg to rest on instead of one,
thus giving a greater surface, and preventing the possibility of so much wear
as at present.
And in Fig. 5 we shew the application of a square peg h for
the accomplishment of the same object. In Fig. 6 we represent an improved
spring for the end of the peg to rest against, which spring shewn at i is
enclosed in a recess in the body of the shuttle, and as it requires no pin to
support it, and no slot underneath, a certain amount of economy and strength
is gained. In Fig. 7 we represent. our improvements for weaving with-gold
thread; the shuttle peg is shewn at kc, and the bobbin at 1, behind which we
place a conical tube m formed of some elastic material, by which means the
gold thread is prevented from coming off sideways, and thereby saves the
ordinary breakage and waste. Instead of the round spindle for the picker to
work on we make it square, and place metal' bushes in the picker to fit the
square spindle, and where the picker strikes the shuttle, we make a hole
through it with a series of parallel threads in it,. as shewn in Fig. 8, or a
number of spiral threads, as shewn in Fig. 9, so that by placing a piece of
caoutchouc, or other elastic material to strike against the shuttle, the interior
threads will keep it firm in its place, and we also, when desired, place cushions
of leather or elastic material on the ends of the picker, as shewn at t.
Our improved arrangement for wetting the ends, of the cops is shewn in
vertical section at Fig. 10, and in plan at Fig. 11. Upon a plate n any
suitable number of conical tubes o are soldered or otherwise fastened, and the
sides of the plate furnished with springs p in order to keep it steady; the said
plate with the tubes are placed upon or above water in a vessel g, so that the
bottom ends of the cops r may enter the water, and become wetted as desired.
On the outside of the vessel there is a single pipe s, so that the operative may
dip the end of the cop into the water whenever it is required. In Fig. 12
we shew at u an additional check strap. to act against the back part of the
picker at the bottom where it gives the blow, in order to relieve and resist the
shock, and thereby prevent bending or breaking.
Having thus fully described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
distinctly understood that we do not confine ourselves to the precise details
herein set forth, as such may be varied or modified without departing from
the principle thereof; but we claim as our Invention, and which, to the best
of our knowledge and belief has not been hitherto used within the realm, the
improved arrangements of the bearing surface of the shuttle peg; the appli-
cation of a conical elastic tube to the shuttle peg in weaving with gold thread;

page_text: improvements in metal pickers; the employment of a tubular frame working
in a vessel containing water for wetting the ends of the cops, and the use of
an additional check strap, as herein described and illustrated in the accom-
panying Sheet of Drawings.
In witness whereof, I, the said William Dawson, for and on behalf of
myself and the said Thomas Singleton, have hereunto set my hand
and seal, this Fifth day of April, in the year of our Lord One thousand
eight hundred and sixty.
WILLIAM DAWSON. (L.s.)
