PROVISIONAL SPECIFICATION.
An Improved Folding or Pocket Corkscrew.
I ROBERT CULP of Altenmarkt Barmen Rhenish Prussia in the Empire of
Germany Engineer do hereby declare the nature of this invention to be as
follows:-
My said invention relates to an improved folding or pocket corkscrew and
consists in an improved construction whereby the screw can be boxed in and
protected when not in use and uncovered when desired. The shank of the cork-
screw is formed with a head to which I hinge or pivot two box arms. To the outer
ends of the said box arms I also hinge two other box arms in the fashion of a rule
joint the said second box arms being connected by links passing on each side of the
corkscrew. The pivotted and linked ends of the connected box arms are or may
be geared together. The box arms being of equal length will lie parallel to each
other either when doubled up or opened out. When doubled up they extend an
equal distance on each side of the head of the corkscrew and at right angles thereto
presenting a gripping handle to the person using the instrument.
When opened
out or rather when folded together in the contrary direction they lie parallel with
the corkscrew and being box or trough shaped they envelope or shroud the screw
so that the instrument can with safety be carried in the pocket.

COMPLETE SPECIFICATION.
An Improved Folding or Pocket Corkscrew.
I ROBERT CULP of Altenmarkt, Barmen, Rhenish Prussia, in the Empire of
Germany Engineer 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 and accompanying drawings :-
My said invention relates to an improved folding or pocket corkscrew and
consists in an improved construction whereby the screw can be boxed in and
protected when not in use and uncovered when desired. The shank of the cork-
screw is formed with a head to which I hinge or pivot two box arms. To the
outer ends of the said box arms I also hinge two other box arms in the fashion of
a rule joint the said second box arms being connected by links passing on each side
of the corkscrew. The pivotted and linked ends of the connected box arms are or
may be geared together. The box arms being of equal length will lie parallel to
each other either when doubled up or opened out. When doubled up they extend
an equal distance on each side of the head of the corkscrew and at right angles
thereto presenting a gripping handle to the person using the instrument.
When
opened out or rather when folded together in the contrary direction they lie
parallel with the corkscrew and being box or trough shaped they envelope or
shroud the screw so that the instrument can with safety be carried in the pocket.
To render my invention more easily understood I will now proceed to describe
the same with reference to the annexed sheet of drawings:
Fig. 1 is a view of the box corkscrew as it appears when uncovered and ready
for use.
Fig. 2 shows the corkscrew as it appears when boxed up for carrying in the
pocket or otherwise.

page_text: Fig. 3 shows the position assumed by the box arms in the act of shifting.
Figs. 4 to 7 illustrate details of the construction.
In the drawings the screw is marked k. The handle as a whole is marked G in
Fig. 1. This handle is composed of trough or box arms 9 9 9 9.
To the flattened
top of the screw & I secure links 6 by means of rivets o and to the said links b two
of the box arms 9 are pivotted by the same rivets o. The other two box arms g
are hinged to the outer ends of the first arms at a and are also hinged together by
the links b. The consequence is that the box arms g g 9 g can either be moved to
lie side by side at right angles to the corkscrew so as to form a handle as in Fig. 1,
or the said arms can be moved to lie parallel with the screw and so as to enclose
and protect the same as in Fig. 2. Fig. 3 is introduced chiefly for the purpose of
showing the position of the box arms in their transition from one position to
another. A stop might project from the cap to keep the box arms g
from closing
down on the screw. The cap h is shown separately at Fig. 6. In some cases the
meeting ends of the box arms might be furnished with teeth so as to gear
together and secure simultaneous movement.
This gearing of the arms g together is shown at Fig. 2 and separately at Figs. 4
and 5 of the drawings.
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:
A corkscrew having a handle capable of being moved so as to enclose and
protect the screw when not in use and to render it capable of being carried in the
pocket without danger to the person, the said handle being composed of hollow
trough shaped or box arms hinged to the corkscrew and to each other and arranged
and operating substantially as described and shown.
