IMPROVEMENTS IN WEFT FORKS USED IN LOOMS FOR WEAVING
Year: 1872

page_text: LETTERS PATENT to Samuel Cook, of Bury, in the County of Lancaster,
Spring Maker, for the Invention of "IMPROVEMENTS IN WEFT FORKS
USED IN LOOMS FOR WEAVING."
Sealed the 15th November 1872, and dated the 18th May 1872.
PROVISIONAL SPECIFICATION left by the said Samuel Cook at the
Office of the Commissioners of Patents, with his Petition, on the
18th May 1872.
I, SAMUEL COOк, of Bury, in the County of Lancaster, Spring
Maker, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN WEFT FORKS USED IN LOOMS FOR WEAVING," to be as follows:-
This Invention relates to weft forks made of sheet metal, and consists
in an improved mode of fixing the bush or barrel to the body of the fork.
Instead of soldering the bush or barrel to the fork I fix it by bars or
clamps formed out of the metal, the bars or clamps being central with
the spaces between the prongs of the fork. The bars or clamps are
formed from the solid body of the fork by ordinary punches and dies, and
when the bush or barrel is placed inside them they are squeezed or pressed
tightly upon it, and thus the bush or barrel is held firmly in its place.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Cook in the Great Seal Patent Office on
the 18th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
Cook, of Bury, in the County of Lancaster, Spring Maker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Samuel Cook, Her special license that I,
the said Samuel Cook, my executors, administrators, and assigns, or
such others as I, the said Samuel Cook, 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 WEFT FORKS USED
IN LOOMS FOR WEAVING," upon the condition, amongst others, that I,
the said Samuel Cook, by an instrument in writing under my hand and
seal, 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.
NOW KNOW YE, that I, the said Samuel Cook, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Figures on the accom-
panying Sheet of Drawings, and to the letters of reference marked
thereon (that is to say) :-
This Invention relates to weft forks made of sheet metal, and consists
in an improved mode of fixing the bush or barrel to the body of the
fork, Instead of soldering the bush or barrel to the fork I fix it by
bars or clamps formed out of the metal, the bars or clamps being
at the bottom central with the spaces between the prongs of the fork,
and at the top in line with them, or vice versa.
The bars or clamps are
speedily formed from the solid body of the fork by ordinary punches and
dies, and when the bush or barrel is placed inside them they are squeezed

page_text: or pressed tightly upon it, and thus the bush or barrel is held firmly in
its place.
On the accompanying Sheet of Drawings Figs. 1 and 2 are side and
front elevations, and Fig. 3 a plan of one of my improved weft forks
complete; Fig. 4, a side view of the fork without the bush; Fig. 5, a cross
section of the body of the fork shewing the bars or clamps; and Fig. 6,
a view of one of the bushes detached.
In one or other of the various Figures a represents the body of the
fork; b, the prongs; and c, the hook in connection with the body; d, the
top and bottom bars or clamps pressed up and down from the metal;
e, the spaces resulting from the formation of the bars; and f, the bush
shewn detached in Fig. 6 and firmly pressed by the bars or clamps in
Figs. 1, 2, and 3.
Weft forks have before been made out of sheet metal without bushes,
or with bushes soldered on them, but the former are imperfect and
unsteady, and the latter expensive, in consequence of the bushes
frequently coming off, whereas when the bars or clamps are firmly
pressed on the bushes, weft forks are made of great strength and
economy.
Having now described the nature and particulars of my said Inven-
tion, and the manner in which the same is to be performed, I desire it
to be understood that in the manufacture of weft forks from sheet
metal I claim, the combination of the bushes with the bars or clamps,
both being firmly pressed together as herein described and illustrated
on the accompanying Sheet of Drawings.
In witness whereof, I, the said Samuel Cook, have hereunto set
my hand and seal, this Fourteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-two.
Signed, sealed, and delivered by the
within-named Samuel Cook, in
the presence of
G. SEPTIMUS HUGHES,
Patent Agent,
Manchester.
