Year: 1853

page_text: LETTERS PATENT to William Edward Newton, of the Office for
Patents, 66, Chancery Lane, in the County of Middlesex, Civil
Engineer, for the Invention of "AN IMPROVED MANUFACTURE OF
HANDLES FOR KNIVES AND OTHER SIMILAR ARTICLES."-
A commu-
nication.
-
Sealed the 9th August 1853, and dated the 20th June 1853.
PROVISIONAL SPECIFICATION left by the said William Edward
Newton at the Office of the Commissioners of Patents, with
his Petition, on the 20th June 1858.
I, WILLIAM EDWARD NEWTON, do hereby declare the nature of the
said Invention for "AN IMPROVED MANUFACTURE OF HANDLES FOR KNIVES
AND OTHER SIMILAR ARTICLES" to be as follows:-
This Invention consists in making knife and other ornamental
handles of a frame of any of the soft alloys, such as German silver,
Britannia metal, white metal, &c., cast on a wooden core, and with
projecting flanches to form recesses to receive ornamental inlaying,
thus forming a handle with a highly ornamental surface, which may

page_text: be more or less inlaid, with the inlaying secured within the recesses
formed by the metal flanches, whilst, at the same time, the body of the
handle is a block of metal of great strength enclosing a wooden core,
in which the stem of the knife can be secured and held firmly, the
wooden core being firmly held by the metal frame which is cast
thereon. The mould which I employ for this purpose is made of metal,
in four parts, which are fitted together and firmly held by dowel pins.
The two corresponding faces are cut out so that, when put together,
they leave an open space in which is held, the wooden core, and round
which the soft metal frame is cast in the ordinary manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal
Patent Office, on the 20th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of June, in the year
of our Lord One thousand eight hundred and fifty-three, in the seven-
teenth year of Ter reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edward Newton, Her
special license that I, the said William Edward Newton, my ex-
ecutors, administrators, and assigns, or such others as I, the said
William Edward Newton, 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 IMPROVED MANUFACTURE OF
HANDLES FOR KNIVES AND OTHER SIMILAR ARTICLES," being a commu-
nication from abroad, upon the condition (amongst others) that I, the
said William Edward Newton, by an instrument in writing under

page_text: 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 William Edward Newton, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say):
This Invention of "An Improved Manufacture of Handles for
Knives and other similar Articles" consists in making knife and other
ornamental handles by means of a skeleton frame composed of any of
the softer alloys, such as German silver, Britannia metal, white metal,
or other suitable metal cast on a wooden core, and with projecting
flanches to form recesses for receiving ornamental inlaying, the object
being to form handles with a highly ornamental surface, which may be
more or less inlaid. The inlaying is secured within the recesses
formed by the metal flanches, whilst, at the same time, the body of the
handle is a block of metal of great strength enclosing a wooden core,
in which the stem of the knife can be secured and held firmly, the
wooden core being firmly held by the metal frame which is cast
thereon. The mould employed for this purpose is made of metal in
four parts, which are fitted together and firmly held by dowel pins.
The two corresponding faces are cut out so that, when put together,
they leave an open space in which is held the wooden core, and round
which the soft metal frame is cast in the ordinary manner.
Fig. 1, in the accompanying Drawings is a perspective view of an
inlaid handle made upon the improved plan. Fig. 2, is a cross section
thereof. Fig. 3, is a perspective view of the cast metal frame before
it is inlaid. Fig. 4, is a perspective view of the entire mould. Fig, 5,
is a cross section thereof; and Fig. 6, another section taken in the
line A, a, of Fig. 5. The same letters indicate like parts in all the
Figures.

page_text: The mould is made of metal in four parts a, b, c, d.
The two parts a, b, are fitted together, and firmly held by dowel
pins e, e.
The two corresponding faces are cut out so that, when
put together, they leave an open space corresponding with the form
of the frame, Fig. 3, and the two faces are grooved out to form the
flanches f.
At g, Fig. 6, the parts a, and b, of the mould are cut out to receive
and (when put together) to firmly grasp the end of a core of wood h,
which, when thus griped, lies properly within the cavity of the mould.
This core should be made of well seasoned wood or other equivalent
substance, well baked, and the butt end i, should be made larger than
the other end to prevent it from coming out of the metal frame when
the latter is cast thereon.
When the two parts a, and b, Fig. 5, are thus put together the
other two parts c, and d, are then secured, one on each side, by dowel
pins, thus binding the whole together.
The faces of the parts c, and d, are so formed as to leave an open
space j, and , all around, so as to produce the flanches f, on the metal
frame, leaving a recess in each face to receive the ornamental inlaying,
which may be secured by successive coats of varnish, such as that used
in the manufacture of articles of papier maché, as represented in
Figures 1, and 3.
The inside of the mould can, if desired, be so formed that the
frame, when cast, will have recesses to receive the inlaying only on
two faces.
The end of the mould should be formed with a space or gate 1,
Fig. 4, through which the molten metal is to be poured to run all
around the wooden core, which is thus effectually confined and firmly
held.
When the frame is cast as represented at Fig. 3, the recesses are to
be properly cleaned out, and then inlaid in the usual or any other
approved manner, and provided with any amount of suitable ornament;
the metal projecting edges or flanches may then be polished or otherwise
finished, and the core can be bored out to receive the stem of a knife
or other instrument to be secured and held therein.

page_text: Having now described the Invention that has been communicated to
me as aforesaid, I do not wish to be understood as limiting myself
to the number of faces to be inlaid, nor to the kind or the quality of
the inlaying, nor to the kind of alloy to be used for casting the frame,
as these may be varied at the discretion of the manufacturer; but what
I do claim as new in the manufacture of handles for knives and other
articles is, the combination, by means of casting, of a wooden core
with a metal frame provided with flanches or ribs to form recesses to
receive ornamental inlaying, for the purpose and in the manner above
described.
In witness whereof, I, the said William Edward Newton, have
hereunto set my hand and seal, the Twentieth day of Decem-
ber, in the year of our Lord One thousand eight hundred and
fifty-three.
