Improvements in or relating to Pocket or Folding Cork-screws
and the like.
I, EDUARD BECKER, of Solingen, in the Empire of Germany, 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;
-
This invention relates to an improved pocket or folding cork-screw.
In the annexed drawing; on Sheet 1;
Fig. 1 is a side view of the cork-screw closed.
Fig. 2 is an upper view of the same.
Fig. 3 shows a side view of the cork-screw when opened.
On Sheet 2. Figs. 1 to 3 are similar views showing the corkscrew fitted to a
pocket knife.
This improved cork-screw consists of two principle pieces and the screw when
opened stands firmly fixed in the operative position without the aid of a spring.
The casing is open at the front and is provided at one end of its back
part with a tongue a¹, and a suitable housing for receiving the square head b¹ of
the screw (Fig. 1) when the device is closed.
The tongue al operates as a spring and is slightly bent for this purpose.
In each side of the casing a there is arranged a slot a³, which slots are so cut in
the casing that their ends which are towards the middle of the casing approach
somewhat nearer to the back of the casing than their other ends, so that these slots
are a little inclined towards the centre of the back of the casing.
The screw has a square head 61, which is kept and guided in the slots a2 by
two pins 63.
T
In the sides of the casing a there is also provided a hollow for allowing of the
opening by hand of the screw.
When the screw lies in the casing, it is kept in this position by the action of
the spring tongue a¹ which presses against the square head b¹, and the head of
the screw lies with one of its edges against one of the edges of the hollow in the
casing and by this means as well as by the tongue is prevented from displacement.
When the cork screw is to be opened the screw b is opened from the casing and
guided to the middle of the socket a. By means of the inclined position of
the slots a the head of the screw b is pressed against the back of the casing, so
that the screw is fixed completely when in the position shown in Fig. 3. The
slots are of such length, that as the head of the screw is worn the screw can be
fixed further along in the casing. The casing a can also be applied to a knife
or the like.
This construction is shown in Figs. 1 to 3 of Sheet 2. The casing a is here
made as an ordinary knife casing, of two side parts and a spring back or dia-
phragm part of which takes the place of the tongue a¹ before described.
The slots can be open or can be suitably covered on the outside, as for
instance, as shown in Fig. 1 of Sheet 2.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
An improved pocket or folding cork-screw, in which the back of the casing
is provided with a housing and a tongue or spring for keeping the same in
the closed position, and the screw when being opened is guided by pins in lateral
slots in the slides of the casing and which are inclined towards the back of the
casing and hold the same screw in the operative position when the screw is placed
in the proper open position.
