Improvements in Handles for Files and the like Tools.
I, HEINRICH RINGEL, of Elberfeld, Ernststrasse, No. 7, Germany, Merchant,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved handle for files and such tools requiring
similar handles. It has for its object to produce a handle from which the ferrule
can not be stripped off and which will not be split by introducing in it the pointed
end or fang of the tool.
I attain these objects first, by giving the ferrule such a shape and providing it
with a sort of counter teeth, so that when put upon the head of a handle these
teeth can be driven into the circumference of the handle and therefore prevent
the stripping off of the ferrule from the handle; secondly by making the hole for
introducing the pointed end or fang conical and inserting into it a conical spiral
spring, which then takes hold of the end like a screw thread in many points, when
driven in firmly, and which at the same time prevents the splitting of the handle;
thirdly by using a circular hole in the handle in place of the conical hole, just
mentioned, and filling it out with a cylindrical spiral spring into which a wooden
bush has been introduced with a small boring so that the pointed end of the tool
can be inserted therein. This wooden bush is placed at a suitable distance in the
spiral spring so that not only the pointed end of the tool will be held by it, but
that also at the thicker or upper end the fang will be held firmly by the spiral
spring at the top of the handle.
On the accompanying drawing:
Fig. 1 shows the handle with the new ferrule alone Figs. 2 & 3 show the tool in
dotted lines both with a conical spiral spring and with a cylindrical piral spring
and the wooden bush inserted therein.
It is evident, that either of the parts, that is the spiral springs and the ferrule
with the counter teeth may be used without the other part, but of course then
the handle is not so complete as if when both parts are combined in a handle."

I, HEINRICH RINGEL, of Elberfeld, Ernststrasse, No. 7, Germany, Merchant,
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 follow-
ing statement:-

I attain these objects first by giving the ferrule such a shape and providing it
with a sort of counter teeth, so that' when put upon the head of a handle these
teeth can be driven into 'the circumference of the handle and therefore prevent
the stripping off of the ferrule from the handle; secondly by making the hole for
introducing the pointed end or fang conical and inserting into it a conical spiral
spring, which then takes hold of the end like a screw thread in many points, when
driven in firmly, and which at the same time prevents the splitting of the handle;
thirdly by using a circular hole in the handle in place of the conical hole, just'
mentioned, and filling it out with a cylindrical spiral spring into which a wooden
bush has been introduced with a small boring so that the pointed end of the tool
can be inserted therein. This wooden bush is placed at a suitable distance in the
spiral spring so that not only the pointed end of the tool will be held by it, but
that also at the thicker or upper end; the fang will be held firmly by the spiral
spring at the top of the handle.
On the, accompanying drawing:

î
Fig. 1 shows the handle with the new ferrule alone;
:
Fig. 2 shows the same, partly in section with the conical spiral spring;
Fig. 3 shows the new handle with a cylindrical spiral spring and a wooden bush
inserted therein.
From Fig. 1 it will be seen that the ferrule A is provided at its circumference
with triangular incisions B, thus forming a sort of a tongue C, which, when the
ferrule is placed over the head of the handle can be driven into the circumference:
of the same, as indicated by the figures, and then prevents the ferrule from falling
or being taken off the handle.
:
In order to give a secure hold also to the fang of the file or other tool used with
the handle, I put into the hole of the same, in which the fang is inserted, a conical
spiral spring D (Fig. 2) corresponding in shape to the shape of the hole, but of
slightly smaller diameter; into the hole, the sides of which. are, as I may say,
thus lined with the spiral spring, I then force the fang of the tool, so that its sides
have the tendency to drive asunder the spring and its windings; these therefore
give a multiple grip to the fang and hold it fast while at the same time, being
driven outwards, the windings of the spring also take a firm hold of the handle 3
itself and it will thus be understood that both the file or other tool and the handle
are firmly connected together. The border E of the ferrule also hinders the falling
out of the spring when no file is placed therein.
case..
The arrangement shown by Fig. 3 differs from the preceding one by the form
of the spring D₁ and the hole in the handle, which in this case are. cylindrical. 4
At the lower end of the spring a wooden bush F is inserted into, the spring; this
bush is bored out so, that the end of the fang of the tool can be stuck therein,
whilst its upper and wider part touches the windings of the spring and drives
them asunder in being driven into the handle in a similar manner as in the former
By this arrangement therefore the fang of a tool is held at its upper end 4
by the spring and at its lower end by the wooden bush, which itself fits closely
to the inner side of the windings of the spring; these therefore also hold it like
a screw and a tool thus connected with the handle will also be held fast therein.
In both cases the spiral springs also guard the handle from being split by driv-
ing a tool too firmly into it. These handles will. therefore last much longer than 5
ordinary handles besides giving a better hold to the tool connected therewith.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
1.) In a handle for files and other tools providing the ferrule A with incisions B 5
so as to form tongues C which can be driven into the wood after the ferrul has

page_text: been put upon the head of the handle and so hinders the falling and the driving
off of the ferrule from the handle as described and illustrated and for the purpose
set forth.
2.) In a handle for files and other tools the combination of the handle having
a ferrule A secured to its head with a conical spiral spring D placed inside the
hole of the handle for the fang of the tool, as described and illustrated and for
the purpose set forth.
3.) The combination of a handle for files and other tools with a ferrule A, a
cylindrical spiral spring D¹, inserted therein, and a wooden bush F placed inside
said spring the whole as described and illustrated and for the purpose set forth.
