Improved Means for Fixing the Blades of Knives, Forks, and the
like to their Handles.
I, ERNST HAMMESFAHR, of No. 7, Foche, Solingen, Prussia, in the German
Empire, do hereby declare the nature of this invention to be as follows:-
My invention relates to improved means for fixing the handles to the blades of
knives, forks, and the like, and it consists mainly in providing the knife blade or
fork with a double or fork-shaped tang which is made to pass along each side of
the handle and is secured thereto in any desired manner. The invention is more
particularly applicable to handles formed of one piece, whether solid or hollow;
it may however also be applied to handles composed of two or more pieces.
On the accompanying drawings are shewn several examples of the manner of
carrying out the said invention.
In the arrangement shewn in side view and cross section at Fig. 1, the blade is
provided with a double or forked tang a a, the limbs of which are formed with an
internal projection or tooth bb near their ends, these teeth being arranged either
symmetrically or out of line with each other, as shewn.
For securing the blade to the handle c the limbs a a are bent slightly apart, the
handle is then introduced between them, after which the limbs are pressed against
the handle and the teeth are forced into the substance of the latter.
The flimbs u a, instead of extending along the entire length of the handle, may
only extend a sufficient distance for holding the blade securely, as shewn at Fig. 2,
the teeth 6 being, as before, either opposite, as shewn, or out of line.
Fig. 3 shews a blade with tang limbs a a baving each two or more teeth b. The
cross section of the tang limbs may either be rectangular as at Figs. 1, 2 and 3, or
round, or oval in the sections, as at Figs. 4 and 5, and they may either be sunk
flush with the handle, or project beyond the same.
Fig. 6 shews a blade the tang limbs a a of which have in addition to the
teeth b, b, at intermediate points, other teeth at the ends, the tangs being of
such a length that when the handle has been introduced between them their ends
can be bent round the end of the handle and the teeth be driven into such end
as shewn.
With this arrangement, the lateral teeth 6 can also be omitted, the tangs being
securely held by the teeth 6¹.
The blade can also be made with the forked tangs a a so formed as to pass down
the flat sides of the handle c as shewn at Fig. 7. If the arrangement of forked
tangs shewn at Figs. 1 to 8 is to be applied to metal handles, the tangs are
provided, in place of the sharp teeth, with pins, studs, or projections which are
forced into corresponding holes in the handle, as indicated at Fig. 9.
The two tang limbs can also be formed into a closed loop as shewn at a³ a³
Fig. 10.
Tangs of this form are more particularly applicable to handles made of material
that can have their form altered by pressure, for example, of soft metal or of
materials that are first produced in a plastic form and that afterwards harden, such
as of wood pulp, papier maché, &c., or handles made of hollow metal. The
securing of the two parts together is in this case effected by first bringing the
handle to such dimensions that it will fit into the loop of the tang, after which it is
subjected to pressure on both sides so as to become flattened out and consequently
fold more or less round the edges of the loop, which will then be situated in a
groove of the handle, as indicated at Fig. 11.
The cross section of the tang limbs can be variously modified, as shewn for

page_text: example at Fig. 12; the dotted section shews the form of the handle of plastic
material before being pressed, while the section in full lines shews the same after
pressing, in the fixed position confined between the tang limbs a³ a³.
In the section shewn at Fig. 13 the tangs are of a flat form, and they are
pressed round or into the handle as shewn in the sections.at Fig. 14.
The tang limbs a' a can-be made to extend over the entire side surface of the
bandle, as shewn at the left hand side, or they may be of a less width as shewn on
the right hand side.
The tang limbs may also be connected at their ends by other suitable means;
thus for instance the two tang limbs as a can be connected by a plate d as at
Fig. 15. This plate or cross bar is pushed over the two ends of the tang limbs
which are then riveted over it, or otherwise secured.
The tang limbs are advantageously sunk into corresponding grooves in the
handle, as at Figs. 1, 2, 3, 7, 10, 11, or they may project more or less as at Figs. 4,
5 and 6, or, according to circumstances, as for example when of a thin fint section,
they may project entirely beyond the handle as at Figs. 8, 9, and 13.
The mode of securing the handles by forked tangs and teeth bb' is particularly
suitable for securing wooden handles to their blades.
As already stated however, this method of securing the handles can be applied
to handles of any material that will securely hold the teeth bb' when these are
forced into them.

COMPLETE SPECIFICATION.
Improved Means for Fixing the Blades of Knives, Forks, and the
like to their Handles.
I, ERNST HAMMESFAHR, of No. 7 Foche, Solingen, Prussia in the German
Empire, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My invention relates to improved means for fixing the handles to the blades of
knives, forks and the like, and it consists mainly in providing the knife blade or
fork with a double or fork-shaped tang which is made to pass along each side of
the handle and is secured thereto in any desired manner. The invention is more'
particularly applicable to handles formed of one piece, whether solid or hollow; -it
may however also be applied to handles composed of two or more pieces.
On the drawings accompanying my Provisional Specification are shewn several
examples of the manner of carrying out.the said invention.
In the arrangement shewn in side view and cross section at Fig. 1 the blade is
provided with a double or forked tang a a, the limbs of which are formed with an
internal projection or tooth near their ends, these teeth being arranged wither
symmetrically or out of line with each other, as shewn.
For securing the blade to the handle c the limbs a a are bent slightly apart, the
-handle is then introduced between them, after which the limbs are pressed against
the handle and the teeth are forced into the substance of the latter. The
..limbs au instead of extending along the entire length of the handle, may only
.extend a sufficient distance for holding the blade securely, as shewn at Fig:2; the
teeth being, as before, either opposite, asishewn, or out of line.
Fig. 3 shews a blade with tang limbs a a having each two or more teeth b: The
cross section of the taug limbs may either be rectangular.as at Figs. 1, 2 and 3. or
round or oval in their sections, as at Figs. 4, and 5, and they may either be sunk
flush with the handle, or project beyond the same.
Fig. 6 shews a blade the tang limbs a a of which have, in addition to the

page_text: teeth bb, at intermediate points, other teeth 6 at the ends, the tangs being of
such a length that, when the handle has been introduced between them, their ends
can be bent round the end of the handle and the teeth 6' be driven into such end as
shewn.
With this arrangement, the lateral teeth b can also be omitted, the tangs being
securely held by the teeth b'.
The blade can also be made with the forked tangs a a so formed as to pass down
the flat sides of the handle c as shewn at Fig. 7. If the arrangement of forked
tangs shewn at Figs. 1 to 8 is to be applied to metal handles, the tangs are provided,
in place of the sharp teeth bb, with pins, studs or projections which are forced into
corresponding holes in the handle, as indicated at Fig. 9.
The two tang limbs can also be formed into a closed loop as shewn at a² a²
Fig. 10. Tangs of this form are more particularly applicable to handles made of
materials that can have their form altered by pressure, for example, of soft metal
or of materials that are first produced in a plastic form and that afterwards harden,
such as of wood pulp, papier maché &c., or handles made of hollow metal. The
securing of the two parts together is in this case effected by first bringing the
handle to such dimensions that it will fit into the loop of the tang, after which it
is subjected to pressure on both sides so as to become flattened out and consequently
forced more or less round the edges of the loop, which will then be situated in a
groove of the handle, as indicated at Fig. 11.
The cross section of the tang limbs can be variously modified, as shewn for
example at Fig. 12; the dotted section shews the form of the handle of plastic
material before being pressed, while the section in full lines shews the same after
pressing, in the fixed position confined between the tang limbs a³ a³.
In the section shewn at Fig. 13 the tangs are of a flat form, and they are pressed
round or into the handle as shewn in the sections at Fig. 14.
The tang limbs at a can be made to extend over the entire side surface of the
handle, as shewn at the left hand side, or they may be of a less width as shewn on
the right hand side.
The tang limbs may also be connected at their ends by other suitable means;
thus, for instance, the two tang limbs as a can be connected by a plate d as at
Fig. 15. This plate or cross bar is pushed over the two ends of the tang limbs,
which are then rivetted over it or otherwise secured.
The tang limbs are advantageously sunk into corresponding grooves in the
handle, as at Figs. 1, 2, 3, 7, 10, 11, or they may project more or less as at Figs. 4,
5 and 6, or, according to circumstances, as for example when of a thin flat section,
they may project entirely beyond the handle as at Figs. 8, 9 and 13.
The mode of securing the handles by forked tangs and teeth 6 6¹ is particularly
suitable for securing wooden handles to their blades.
As already stated however, this method of securing the handles can be applied
to handles of any material that will securely hold the teeth b¹ when these are
forced into them.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. Fixing blades of knives or the like to their handles by means of double tangs
one held on each side of the handle.
2. Holding the handle to the tangs above referred to by teeth formed on the
tangs and pressed into the handle or by an end plate fixed to the tangs.
3. Fixing the handle by pressing the tangs into or around its sides.
