page_text: We ALEXANDER SCHÜNEMANN and CARL SPINDLER of Rödingsmarkt No. 42
Hamburg in the Empire of Germany, Manufacturers 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 machinery for driving corks into bottles jars etc. and it
consists in certain mechanism for compressing the cork preparatory to its insertion into
the bottle or the like such mechanism being applicable to bottling and corking machines
of different kinds.
The object of the invention is principally to compress a cylindrical cork so
that when compressed it may still have a true cylindrical, form; reference being
made to the accompanying drawings. Fig. 1 is a plan view of the mechanism
showing the same in open position. Fig. 2 a section thereof on line x x. Fig. 3
a horizontal section showing the mechanism in the position it occupies with the cork
compressed.
Fig. 4 a vertical section of the same in compressed position. Fig. 5 a detail view
of a part.
In the improved press the cork is laterally compressed between two hinged jaws and
driven thereby against a stationary abutment in the press which has a semi cylindrical
recess into which the cork enters.
The cork retains a true cylindrical form when compressed by arranging the
mechanism in the following manner. The closed jaws engage with each other
at the top by angular projections the interior of which when the jaws are closed
form together a semi cylindrical form which together with the cavity in the
above mentioned stationary part. complete the cylindrical space having the size of
the compressed cork.
The stationary part of the press having the front semi-cylindrical upright cavity
is shown at e. The two side jaws of the press hinged together at d are lettered
a and b.
These parts a and b engage together in the front with projections and include when
closed a semi cylindrical cavity.

page_text: R is the frame within which is the press.
The cork Pas shown in Fig. 1 is put on the lower plate m of the frame between the
open jaws. By compressing the jaws a and b and simultaneously moving them rearward
the cork is compressed and driven into the cavity in the abutment so that the diameter
of the cork is decreased to the necessary amount (Fig. 3).
The closing of the jaws may be attained by journalling thereon rollers n n¹ to ride
upon the inclined planes ii of the frame as soon as the jaws are moved in the frame
from the left to the right side.
The opening of the jaws may result by forming the outer faces of the stationary
parte as a wedge and placing the projections o o on the jaws to ride upon the faces of
said wedge and so press asunder the jaws, as soon as the latter are moved back from
the right to the left side.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is,
1. In corking machinery a press comprising in combination the movable jaws a
and b and the stationary abutment e having a semicylindrical cavity substantially as
set forth.
2. The combination of the jaws a and b and stationary abutment e with the wedge
on the rear of said abutment and the inclined faces oo on the jaws for the purpose
set forth.
