Year: 1863

page_text: LETTERS PATENT to Abraham Bamford, of Belle-flat Street, Richard
Street, Richard Blomley, of Taylor Street, Whitworth Road, and Robert
Taylor, No. 67, Manchester Road, Overlookers of Looms, and James
Lett, of No 9, Water Street, Moulder, all of Rochdale, in the County of
PROVISIONAL SPECIFICATION left by the said Abraham Bamford,
Richard Blomley, Robert Taylor, and James Lett at the Office of the
Commissioners of Patents, with their Petition, on the 2nd January
1863.
We, ABRAHAM BAMFORD, of Belle-flat Street, Richard Street, RICHARD
BLOMLEY, of Taylor Street, Whitworth Road, and ROBERT TAYLOR, No. 67,
Manchester Road, Overlookers of Looms, and JAMES LETT, of No. 9, Water
Street, Moulder, all of Rochdale, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR
WEAVING," to be as follows:-
Hitherto in looms it has been customary to connect the picking stick, when
it has not moved with the lathe, to the picker by means of a strap, band, or
chain; but we propose to connect the picker to the picking stick without the
intervention of the strap, band, or chain, which may be done as follows:-On

page_text: the tappet shaft we have cams, as usual, which work the picking motion;
these cams work against bowls, which are mounted on studs, which are
fastened to two upright shafts, one in each side of the loom; on the top of
these shafts are bolted the picking sticks above the lathe, so as just to clear
it; in the picker are formed two projections, which take hold on each side of
the picking stick, so that when the picking stick moves it takes the picker
along with it without the intervention of a strap, band, or chain.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Abraham Bamford, Richard Blomley, Robert Taylor, and
James Lett in the Great Seal Patent Office on the 1st July 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ABRAHAM
BAMFORD, of Bell-flat Street, RICHARD BLOMLEY, of Taylor Street, and
ROBERT TAYLOR, of Manchester Road, Overlookers of Looms, and JAMES
LETT, of Number 9, Water. Street, Moulder, all of Rochdale, in the County of
Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date, the Second day of January, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Abraham Bamford, Richard Blomley, Robert Taylor, and James
Lett, Her special license that we, the said Abraham Bamford, Richard
Blomley, Robert Taylor, and James Lett, our executors, administrators, and
assigns, or such others as we, the said Abraham Bamford, Richard Blomley,
Robert Taylor, and James Lett, 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 "IMPROVEMENTS IN LOOMS: FOR WEAVING," upon the condition (amongst
others) that we, the said Abraham Bamford, Richard Blomley, Robert
Taylor, and James Lett, our executors or administrators, by an instrument in
writing under our, or their, or one of our or their hands, and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be 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.

page_text: NOW KNOW YE, that we, the said Abraham Bamford, Richard Blomley,
Robert Taylor, and James Lett, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement and
accompanying Drawings (that is to say) :-
Hitherto in looms for weaving it has been customary to connect the picking
stick, when it has not moved with the lathe, to the picker by means of a strap,
band, or chain.
Now the nature of our Invention consists in connecting the picker to the
picking stick without the intervention of the strap, band, or chain.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Drawing.
Fig. 1. represents. an. end. elevation of a loom. such as. is used to weave
calico, with our Invention applied, and Fig. 2 represents a front elevation of
one end of the same. Both Figures are one-fourth size.
a is the frame side of the loom; b, the driving or crank shaft; .c, the tappet
shaft, on which is mounted the tappet d, which works against the bowl e, and
causes it to vibrate to and fro; this bowl is mounted on a stud e¹, which is
screwed fast to the upright shaft f, which is supported by the brackets f¹ and
f; on the top of the shaft is fastened a plate g, to which is fastened the
picking stick; h is a spiral spring, which keeps the bowl e against the
tappet d; i is the lathe; k, the shuttle-box bottom, which has a slot in it for
the end of the picker to slide in; Z is the shuttle-box front; m, the shuttle-
box back, and n the spindle on which the picker slides; o, in Fig. 2, is the
shuttle-box end, it supports one end of the shuttle-box back, and one end of
the spindle n, it is not shown in Fig. 1, so that the picker and picking stick
might be more distinctly seen. All the parts above enumerated are, as
usually constructed, with the exception of the upright shaft f, which is made
rather shorter, so as to bring the picking stick lower down; and the brackets
fand f, which are made rather longer, so as to throw the upright shaft
rather farther from the loom side; p is the picker, which is made with a slot in
the upper part of it, as shown in Fig. 2, for the end of the picking stick to come
through, so that when the picking stick moves it pushes the picker p backwards
or forwards along the spindle n; by this means the straps, bands, or chains
usually employed to connect the picking stick to the picker are dispensed with.
Having thus particularly described the nature of our Invention, and the
manner of performing the same, we wish it to be understood, that we do not
limit ourselves to the details herein set forth, as many variations may be made
in the mode of connecting the picking stick to the picker; but we claim as our

page_text: Invention of improvement in looms for weaving, connecting the picking stick
(when it does not move with the lathe) to the picker without the intervention
of the straps, bands, or chains usually employed.
In witness whereof, we, the said Abraham Bamford, Richard Blomley,
Robert Taylor, and James Lett, have hereunto set our hands and
seals, this Twenty-sixth day of June; in the year of our Lord One
thousand eight hundred and sixty-three.
