IMPROVEMENTS IN SPORTING AND OTHER POCKET KNIVES."
Year: 1876

page_text: LETTERS PATENT to Thomas, Crookes, of Sheffield, in the County of York,
for the Invention of "IMPROVEMENTS IN SPORTING AND OTHER POCKET
KNIVES."
PROVISIONAL SPECIFICATION left by the said Thomas Crookes at the Office
of the Commissioners of Patents on the 24th February 1876.
THOMAS CROOKES, of Sheffield, in the County of York. "IMPROVEMENTS IN
SPORTING AND OTHER POCKET KNIVES."
Hitherto it has been customary for sportsmen and others to carry a detached
cartridge extractor in their pockets or elsewhere, thereby frequently experiencing
considerable inconvenience when requiring it for use owing to their having either
lost or mislaid it.
this
Now the object of my Invention is to obviate such inconvenience and add to the
utility of a sportsman's ordinary pocket knife or of any other spring knife, which I
do in the following manner, that is to say, I make or form the top or bottom, or if
desired both ends of either one or more of the scales or spring heads of an ordinary
sportsman's knife or the end of any saw, file, or other similar article contained therein,
which is worked by a spring in such a manner that they may be readily and con-
yeniently used for extracting cartridges from any central-fire gun when requisite ;
I do by firmly attaching or affixing by rivetting or by any other suitable means to
either or both ends of one or more such scales or springs, or to the end of the saw, file,
or other article contained in such knife one, two, or more pieces of gun metal, steel,
iron, nickel, or any other suitable metal curved or hooked at both ends, and
otherwise formed in the shape of any ordinary cartridge extractor; or such scales
may be made in one solid piece, having one or both of their ends formed in the
shape of a cartridge extractor and made of a suitable thickness in metal so as to
impart sufficient strength thereto. By this means the liability to its being either
lost or mislaid is greatly reduced, at the same time that it considerably adds to the
utility of the knife itself. If desired such extractors may be made of different sizes
so as to be the more conveniently adapted for use to extract cartridges varying in
shape and size.

"IMPROVEMENTS IN
Hitherto it has been customary for sportsmen and others to carry a detached
cartridge extractor in their pockets or elsewhere, thereby frequently experiencing
considerable inconvenience when requiring it for use owing to their having either
lost or mislaid it.
Now the object of my Invention is to obviate such inconvenience and add to the
utility of an ordinary sportsman's knife or of any other pocket knife, which I do in
the following manner, that is to say I make or form the top or bottom, or if desired
both ends of either one or more of the metal scales or springs of an ordinary
sportsman's knife or of any other pocket knife, in such a manner that they may be
readily and conveniently used for extracting cartridges from any central-fire gun
when requisite; this I do by firmly attaching or affixing by rivetting or by any
other suitable means to either or both ends of one or more of such scales or springs
one, two, or more pieces of gun metal, steel, iron, nickel, or any other suitable metal
. curved or hooked at both ends or sides, and otherwise formed in the shape of any
ordinary cartridge extractor; or such scales or springs may be made in one solid
piece having one or both of their ends formed in the shape of a cartridge extractor
and made of a suitable thickness in metal so as to impart sufficient strength thereto.
By this means the liability of its being either lost or mislaid is greatly reduced at
the same time that it considerably adds to the utility of the knife itself. If desired
such extractors may be made of different sizes so as to be the more conveniently
adapted for use to extract cartridges varying in shape and size.
Having thus particularly described and ascertained the nature of my said
Invention, and the manner of carrying the same into effect, I would have it
understood that what I claim and desire to secure by the herein-before in part
recited Letters Patent is, the forming either the top or bottom, or if desired both
ends of either one or more of the metal scales or springs of an ordinary sportsman's
knife or of any other pocket knife so that they may be readily used for extracting
cartridges from any central-fire gun, substantially in the manner herein-before set
forth and described.
In witness whereof, I, the said Thomas Crookes, have hereunto set my hand
and seal, this Twenty-first day of August, in the year of our Lord One
thousand eight hundred and seventy-six.
