Knives, and similiar Articles.
I, CHARLES IBBOTSON, of 58 Cambridge Street, Sheffield, in the County of York,
Cutlery Manufacturer, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN HANDLES FOR TABLE CUTLERY DAGGER AND SHEATH KNIVES,
AND SIMILIAR ARTICLES," to be as follows:-
1
This invention relates to improvements in hollow handles formed of thin metallic
substances, and consists in forining a wood centre of the required size to enter the
bolster end of a hollow inetallic handle, the said wood centre being the same length,
or nearly so, as the handle, the end nearest the bolster being slightly taper, leaving
a space all round the said centre and the case of the handle.
In carrying my invention into effect I about half fill the handle with hot resin
or other cement and insert the wood centre through the resin to the bottom of the
inside of the handle, which forces the said resin all round between the centre and
the handle; the resin is then prepared to receive white metal or its equivalent,
which is poured over it, covering the top of the wood centre, and, becoming flush
with the handle prevents the resin from escaping, as it does by the old system of
fastening. The tang of the blade is then inserted and knocked into the wood
foundation, or through the foundation and rivetted at the extreme end of the
handle, and a rivet passed through the handle, wood foundation and tang, at the
bolster end or in any other convenient position; or the hollow handle as above
described may be made with the wood centre enclosed in a tube of brass or other
suitable metal inserted at the bolster end of the handle and soldered as above
described; or the two can be soldered together by the ordinary process of a blow-
pipe, the said metal tube being a preventative against the tang being driven through
the side of the wood centre into the resin; or the bolster end of the said hollow
handle may be fitted with a piece of brass or other suitable metal formed to the
required shape and soldered to the mouth or bolster end of the handle, having a
hole in the centre to receive the tang, which is screwed into it, thereby making
the handle and tang secure.

I, CHARLES IBBOTSON of 58 Cambridge Street, Sheffield, in the County of York,
Cutlery Manufacturer, do hereby declare the nature of my said invention for
"IMPROVEMENTS IN HANDLES FOR TABLE CUTLERY, DAGGER AND SHEATH KNIVES,
AND SIMILIAR ARTICLES" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
This invention relates to improvements in hollow handles formed of thin metallic
substances and cousists in forming a firm and solid centre or foundation by about
half filling the handle, at the bolster end with hot resin or other cement and
inserting a tube of brass or other suitable metal, blocked at one end, the blocked end
being at the bottom of the handle; the resin is prepared to receive white metal or
its equivalent which is poured to come flush with the top of the brass tube, thus
preventing the resin escaping, as it does by the old system of fastening; the tang of
the blade is then inserted and knocked into the tube and a rivet passed through
the handle, tube and tang at the bolster end or in any other convenient position.
Or the hollow handle as above described may be made with a wood centre of the
required size to enter the bolster end, the said centre being the same length, or
nearly so as the handle, the end nearest the bolster being slightly taper leaving a
space all round the said centre and the case of the handle; or it may be made with
the wood centre enclosed in a tube of brass or other suitable metal and soldered
as above described, the said metal tube being a preventative against the tang being
driven through the side of the wood centre into the resin.
The accompanying drawings illustrate my invention :-

Fig. 1. is a longitudinal section through the metallic handle shewing the hollow
tube A in position and the end blocked at D. The dotted lines shew the position
of the wood centre B instead of the hollow tube A and C is the resin or other
cement poured in previous to inserting the hollow tube or wood centre. E is the
white metal, run over the resin, and secures the tube or wood centre to the case of
the handle, at the same time preventing the escape of the resin and the loosening
of the blade when immersed in hot water. F shews the rivet passing through the
handle and the tang of the blade G, securing the whole together and making it
solid and firm.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
Firstly Improvements in the construction of centres or foundations and in the
manner of combining the same to the hollow metallic handles used in the manu-
facture of Table Cutlery, Dagger and Sheath Knives, and similiar articles.
Secondly. In hollow handles formed of thin metallic substances, and consisting of
a tube of brass or other suitable metal blocked at the bottom end and placed
inside the handle which is filled up with resin and soldered as above described,

page_text: Thirdly. In the construction of hollow handles formed of a thin metallic
substance with a wood centre or foundation instead of the brass tube, the handle
being filled up with resin and soldered as before described.
Fourthly. In the construction of foundations for hollow metallic handles,
consisting of a wood centre placed inside a brass tube and the whole placed in the
handle, the said tube preventing the tang being driven through the wood centre
into the resin; the whole being soldered at the tang end prevents the resin running
out and loosening the handle, as it does by the old system of fastening.
Fifthly. In the construction of foundations for hollow metallic handles for Table
Cutlery, Dagger and Sheath Knives and similiar articles, as hereinbefore specified,
described, and illustrated by the accompanying drawings.
