PROVISIONAL SPECIFICATION.
An Improvement in the Method or Process of Preserving Oysters
and other Bivalves in the Shell.
I DAVID EVANS, Needle Manufacturer of Studley, in the County of Warwick,
(a communication from Albert Alen Freeman, 3321 North Broad Street,
Philadelphia, and George Evans, Uniform Clothing Manufacturer, 132 North
5 Street Philadelphia, both in the City & County of Philadelphia, the State of
Pennsylvania, U.S. America) do hereby declare the nature of this invention to be
as follows:-
To tightly close the shells of oysters & other bivalves so that thereby their
juices may be retained & the bivalve be found when opened in a fresh & natural
condition fit for consumption. To attain this the shells of the oyster &c. are
perforated-in one or more places near the bills opposite the hinge of the bivalve.
In these apertures gaps, or openings, is inserted a rivet, which when hammered
down will hold the shells fast together, or a staple, eyelet, piece of wire, or metal,
or their equivalents may be inserted in the apertures, which when compressed or
bent on the shells will firmly keep them closed. Where a single piece of wire or
metal is used, one end thereof-atter being bent or shaped-may be inserted in the
opening at the rear of the hinge of the oyster &c., the piece brought along or over
the bivalve, passed through the aperture or opening near the bills, and this its
other end compressed on the shells-or the two ends passed through apertures in
the shells on opposite sides of the bivalve, & then compressed thereon so as firmly
to hold the shells together. When the oyster &c. is to be opened, the rivet &c.
may be removed by the breaking of the shells for the insertion of the knife.
Dated this Seventh day of December 1891.

COMPLETE SPECIFICATION.
An Improvement in the Method or Process of Preserving Oysters
and other Bivalves in the Shell.
A communication from ALBERT ALEN FREEMAN, 3321, North Broad Street,
Philadelphia, and GEORGE EVANS, Manufacturer of Uniformn Clothing,
132, North 5 Street, Philadelphia, both in the City and County of Philadelphia,
State of Pennsylvania, U.S. America.
DAVID EVANS, Needle Manufacturer, of Studley, in the County of Warwick
I 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 :-
To tightly close the shells of oysters and other bivalves so that thereby their
juices may be retained and the bivalves be found when opened in a fresh and
natural condition fit for consumption. To attain this, the shells of the oyster &c.
are perforated (in one or more places) near the bills opposite the hinge of the
bivalve. In these apertures, gaps, or openings is inserted a rivet, which when
hammered down will hold the shells fast together, or a staple, eyelet, piece of wire
or metal or their equivalents may be inserted in the apertures or openings, which
when compressed or bent on the shells will firmly keep them closed. Where a
single piece of wire or metal is used, one end thereof, after being bent or shaped,
may be inserted in the opening at the rear of the hinge of the oyster &c., the piece
brought along or over the bivalve, passed through the aperture or opening near the
LD

page_text: bills, and this (its) other end compressed on the shells, or the two ends passed
through apertures in the shells on opposite sides of the bivalve and then compressed
thereon, so as firmly to hold the shelts together. When the oyster &c. is to be
opened, the rivet &c. may be removed by the breaking of the shells for the insertion
of the knife.
That this invention may be fully understood I annex drawings and describe
them.
Fig. 1 represents an oyster with apertures or openings B. C. in its shells on
opposite sides.
Fig. 2 represents the bivalve secured by the binder E.
Fig. 3 represents a cross section at B. C showing one mode of securing the shells
of the bivalve by this invention. It will be seen that the binder E is passed across
the shell on one side of the bivalve, through the openings or recesses B. C. in its
shells and the ends of the binder compressed or hammered on the other side of
the bivalve, thus preventing the opening of its shells till the binder is removed.
Fig. 4 represents a bivalve with an opening in its shells opposite the hinge
thereof.
Fig. 5 shows the bivalve secured by the binder D.
Fig. 6 represents a longitudinal section of the bivalve showing the binder D with
one end inserted in the opening F at the rear of the hinge of an oyster and then
continued along it, through the opening near its bills (A Figs. 4 and 5) and its
other end compressed on the opposite shell.
Fig. 7 represents another mode of securing the shells under this invention viz. by
rivet, the opening for which is shown at G.
Fig. 8 represents the bivalve's shells secured by the rivet H.
Fig. 9 represents a cross section of Figs. 7 and 8 with a portion of the shells
broken away to show the rivet and the mode of securing the shells by this
method.
I have not shown the method of securing the shells by staples as it will be
obvious that with two openings instead of one-as in Fig. 7-the end will be
attained, also that, if in place of the rivet (H Fig. 8) an eyelet be used the same
result will be reached and the shells held together firmly. It is also plain that
the precise processes described may be varied without departing from the
invention.
Having described the invention and how it may be carried out, what. I claim
and wish to secure is,
The method of preserving or securing oysters and other bivalves in their shells,
by passing through openings therein, rivets, staples eyelets, wires or their
equivalents, to prevent the opening of the shells and the escape of the juices of the
bivalves.
