I JOHANN OCKERMULLER, Manufacturer, of Altmannsdorf, near Vienna in the
Empire of Austria do hereby declare the nature of my Invention for IMPROVEMENTS
IN THE MANUFACTURE OF KNIVES AND HANDLES FOR THE SAME 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 improvements in the manufacture of knives and forks
and handles for the same.
The manufacture of hollow handles for knives and forks from one piece has up
to the present time been found impracticable as such said handles must be light
cheap and durable.
According to my method of manufacture as described further on in this specifi-
cation I have overcome these difficulties and at the same time attained a very
durable attachment of the knife or fork stem.
Figure 1 is a section of a knife handle.
2 an elevation of the same.

"
4 is the elevation of the one half of the inner shell of the handle.
The knife blade m or fork g consists of rolled sheet steel or other suitable metal
or alloy stamped into form. The stem s is in all cases formed of a small strip of
sheet metal bent in the form of a spiral screw.
The shell of the handle consists of two halves e e of sheet iron or steel pressed
up into the appropriate form as shown in Fig. 1 and 4. These two halves e e are
held together by means of the wires d d in order to avoid soldering the same,
which said wires d d are arranged in the grooves n n. The spirally wound or bent
stem is inserted in the rough handle thus formed by the two half shells and the
space between stem and shell filled out by pouring plaster of Paris or other suitable
matter into the said unfilled space. By means of the screw like windings in the
stem and the conicity of the shell the connection between stem and shell by means
of the filling y will be exceedingly strong and durable.
Around this rough shell I now cast the outer case of the handle, that is, the
rough handle is placed in a metallic form made of two pieces, of appropriate form
and somewhat larger than the rough handle so that a readily fusible mass can

page_text: freely flow into the space between the rough handle and the form. For this
purpose I generally employ Brittannia metal although other readily fusible alloys
and especially tin alloys can be employed to great advantage. The alloy encloses
or surrounds the rough handle at all points. Handles made on the system above
described are, as will be evident to all versed in this branch of manufacture,
exceeding strong and at the same time of elegant appearance and in order to still
further increase the durability and good look of the knife or fork I cast a ring or
ferrule a of like metal with the outer casing of the handle between the said handle
and the blade of the knife or upper part of the stem of the fork instead employing
the ordinary iron or brass ferrule, as shown in Fig. 1 and 2. This ring being of
solid metal and of one piece with the handle gives a solid and very elegant finish
to the said handle and so that the handle is very firmly attached to the blade.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The manufacture of the handles of knives and forks characterised by-
1. The application and employment of blades with helically bent stem and
stamped or pressed sheet metal shells ee with grooves n n for receiving the
wires d d for holding the two parts of the said shell together substantially as
described in the foregoing specification and shown in the accompanying drawings.
2. The application and employment of the rough handle composed of the two
halves e e of sheet metal and the filling out of the space within the said sheel and
around the stem of the blade or fork with fire proof plastic material preferably
plaster of Paris for fixing the said stem in the shell and preventing molten metal
from penetrating into the interior of the said sheel e e substantially as described
in the foregoing specification and shown in the accompanying drawings.
3. The method of producing durable handles for knives and forks by casting a
readily fusible alloy such as Brittannia metal or other suitable alloy around the
rough handle e e substantially as described in the foregoing specification and shown
in the accompanying drawings.
•
4. The application and employment of the ring a of one piece with the metal
cast around the rough shell e e thus forming a firm connection between handle
and blade substantially as described and shown in the accompanying drawings.
