"
Hitherto, cartridge extractors were made of various sizes each to fit a
corresponding size cartridge, and it frequently causes considerable inconvenience to
sportsmen, when wishing to extract a smaller size cartridge, than the extractor in
use. Now the object of my Invention is to obviate such inconvenienco, by making
an extractor to fit any size cartridge from 10 or 12 to decimal 500 and add to the
utility of an ordinary sportsman's knife or of any other pocket knifo 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 spring 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 moro 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, and made of a suitable thickness in
metal so as to impart sufficient strength thereto or such metal scales may be made
out of the solid in one piece of suitable thickness, and on the back of any one or
more blades of the knife, and towards the pin or pivot on which the blade turns
I form a small notch or hook, when it is requisite to withdraw a smaller cartridgo.
open
the blade of the knife until the said notch or hook comes in contact with
and grips the rim of the cartridge whilst at the same time one end of the extractor
on the scale grips or holds the corresponding side of cartridge rim, in the usual
manner. By this means I am able to withdraw the largest to the smallest
I

page_text: cartridge made for sporting guns. I prefer to make the said notch or hook on the
back of the champagne opener, button hook, saw file or other similar article for by
placing the thumb under such, any amount of power can be given to the grip.
This Invention is also applicable for withdrawing very small articles, such as nails
from horses shoes.
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 an ordinary sportsman's knife or of any other pocket knife into cartridge
extractors, in combination with the notch or hook formed on the back of the
blade or blades or other article in the knife so as to grip the rim of any size
cartridge for extracting the same 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 Tenth day of August in the year of our Lord One thousand eight hundred
and eighty three.
