Year: 1864

page_text: LETTERS PATENT to Frederick. Walters, of Sheffield, in the County of
York, Cutlery Manufacturer, for the Invention of "AN IMPROVEMENT' IN
PENKNIFE AND POCKET-KNIFE BLADES, AND IN THE MODE OF FIXING AND
EMPLOYING THE SAME.".
Sealed the 13th April 1865, and dated the 20th October 1864.
PROVISIONAL SPECIFICATION left by the said Frederick Walters at
the Office of the Commissioners of Patents, with his Petition, on the
20th October 1864.
I, FREDERICK WALTERS, of Sheffield, in the County of York, Cutlery
Manufacturer, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT IN PENKNIFE AND POCKET-KNIFE BLADES, AND IN THE MODE OF
FIXING AND EMPLOYING THE SAME," to be as follows (that is to say)
My Invention has reference to an improvement in penknife and pocket-
knife blades for enabling the same to be fitted and secured to all descriptions
of handles or holders independently of the springs and pins as at present, by
which a more simple and inexpensive mode of fixing the same to the handles
is obtained, and consists in forming the said blades with a screw upon the

page_text: shank end thereof so as to admit of the same being screwed into a tapped
socket formed or employed in connection with the handle or holder, by which
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Walters in the Great Seal Patent Office on the
19th April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WALTERS, of Sheffield, in the County of York, Cutlery Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Frederick Walters, Her special licence that I, the said Frederick Walters,
my executors, administrators, and assigns, or such others as I, the said Frederick
Walters, 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 "AN IMPROVEMENT IN PENKNIPE
AND POCKET-KNIFE BLADES, AND IN THE MODE OF FIXING AND EMPLOYING THE SAME,"
upon the condition (amongst others) that I, the said Frederick Walters, my
executors or administrators, by an instrument in writing under my, or their,
or one of 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.
NOW KNOW YE, that I, the said Frederick Walters, do hereby declare
the nature of my
said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained-in-and-by the following
statement, and the Drawings therein referred to (that is to say):
My Invention has reference to an improvement in penknife and pocket-
knife blades, for enabling the same to be fitted and secured to all descriptions
of handles or holders independently of the springs and pins as at present, by

page_text: which a more simple and inexpensive mode of fixing the same to the handles
or otherwise is obtained, and consists in forming the said blades with a screw.
upon the fang or shank end thereof so as to admit of the same being readily
screwed into a tapped socket formed- or employed in connection with the
handle or holder and thereby set or re-set when broken, or otherwise ns
required.
And in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawing, reference being had to the letters and figures thereon
marked (that is to say) :-
:-
Fig. 1 represents a side view of my penknife or pocket-knife blade detached
from the handle or holder; Fig. 2, corresponding side view thereof; Fig. 3,
top or plan view of the same; Fig. 4, an edge view; Fig. 5 an end elevation
shewing the fang screw; Fig. 6, a side elevation of a-sliding pencil-case
holder, shewing my improved blade attached thereto; Fig. 7, a longitudinal
section thereof, having the blade removed from the socket; and Figs. 8 and 9,
front and end views of the sliding case or holder. In each Figure the same
letters of reference denote similar corresponding parts.
A, A, the blade; B, B, fang screw formed with the blade, by which the
same is held and secured; C, C, pencil case or holder; D, D, sliding socket
for the reception of the screw blade; E, E, stud or pin for sliding the knife
in or out of the holder; F, F, slot or groove in which the same works.
In conclusion to the foregoing description it may be here necessary to note,
that blades of other forms and dimensions in lieu of the one above described
may be fitted and employed in like manner to any of the various descriptions
of handles or holders as required, and secured thereto either singly or together
with other appropriate instruments; and I would further note that the screw
fang may be fitted or secured to the sliding socket in any suitable manner or
receive such other modifications as may be found desirable.
Having now described the nature of this my said Invention, and the
manner in which the same is to be performed and carried into effect, I
would have it clearly understood that I do not confine myself to the precise
details as the same may be varied without departing from the general
principle of this my said Invention; nor do I claim as of my said Invention
the exclusive use of the separate parts or combinations thereof herein-before
mentioned and described, except when the same are employed in and for the
purposes of my said improvements, which I hereby declare to consist in
fixing or securing peuknife or pocket-knife blades to handles or holders

page_text: through the medium of the tapped screw fang and socket in the manner and
for the purposes herein-before set forth and described.
In witness whereof, I, the said Frederick Walters, have hereunto set my
- hand and seal, this Thirteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-five.

FREDERICK WALTERS. (L.S.)
