IMPROVEMENTS IN THE CONSTRUCTION OF LOOMS FOR WEAVING
Year: 1873

page_text: LETTERS PATENT to Adam Wood, of Oldham, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION
OF LOOMS FOR WEAVING."
Sealed the 29th July 1873, and dated the 22nd May 1873.
PROVISIONAL SPECIFICATION left by the said Adam Wood at the
Office of the Commissioners of Patents, with his Petition, on the
22nd May 1873.
I, ADAM WOOD, of Oldham, in the County of Lancaster, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
CONSTRUCTION OF LOOMS FOR WEAVING," to be as follows:-
This Invention relates to the "picking motion" which effects the
driving of the shuttle with the weft to and fro across the loom, and is
intended to dispense with the arrangements usually employed, and to
effect the "pick" direct from the fly wheel. Upon the inner side of
each fly wheel I bolt a projection, which I term a "hammer," and upon
the side of each picking shaft I cast or fix a cam or projection so placed
that as the "hammer on the fly wheel passes the picking shaft it
"

page_text: strikes against the cam or projection, and thus causes the picking shaft
to be suddenly turned about a quarter of a revolution, and thus gives the
requisite movement to the picking stick.
In order to prevent both picking sticks from acting together, and
to cause them to strike alternately, I have a shaft running across the
lower part of the loom, and upon this shaft I mount a disc or face plate
near to each end, and upon each disc or face plate is a swell or projection
so placed that as the shaft revolves the swells come alternately against a
finger attached to the lower part of each picking shaft, and turn the
latter slightly so as to throw the cam or projection first named out of the
reach of the hammer on the fly wheel, and as this is done alternately on
each side of the loom the action of the picking sticks is necessarily
alternate also.
The shaft which carries the disc or face plates is driven from the
hool and ninion or by other convenient means
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adam Wood in the Great Seal Patent Office
on the 22nd November 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADAM
WOOD, of Oldham, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Adam Wood, Her special license that I,
the said Adam Wood, my executors, administrators, and assigns, or
such others as I, the said Adam Wood, my 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 THE

page_text: CONSTRUCTION OF LOOMS FOR WEAVING," upon the condition (amongst others)
that I, the said Adam Wood, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seal, should particularly describe and ascertain the nature of the said
3 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.
NOW KNOW YE, that I, the said Adam Wood, do hereby declare
> the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, and accompanying Drawings (that is to say) :-
This Invention relates to the "picking motion" which effects the
driving of the shuttle with the weft to and fro across the loom, and is
intended to dispense with the arrangements usually employed, and to
effect the "pick" direct from the fly wheel.
Such being the nature and object of the said Invention I will now pro-
ceed to describe more in detail the manner in which the same is to be or
may be performed or carried into practical effect; and in order that the
same may be clearly understood I have annexed hereunto a Sheet of
Drawings illustrative thereof, and have marked the same with figures
and letters of reference corresponding with those in the following
explanation thereof :-
Fig. 1 in the annexed Drawing is an elevation of part of one end of a
loom, showing the adaptation of my Invention thereto, the apparatus
being shown in the position it assumes when just about to effect the
pick; Fig. 2 is a similar view, when the finger of the picking apparatus
is moved on one side to allow the hammer to pass without acting on the
picking stick.

page_text: shafts, in combination with an arrangement for moving the fingers alter-
nately out of position to be struck by the hammers.
In witness whereof, I, the said Adam Wood, have hereunto set
my hand and seal, this Twentieth day of November, in the year
our Lord One thousand eight hundred and seventy-three.

GEORGE DAVIES, C. E.,
