PROVISIONAL SPECIFICATION.
A. New and Useful Improvement in a Mode or Method of Preserving
Oysters, Clams, and other Bivalves.
A communication from ALBERT ALEN FREEMAN, 3321, North Broad Street, and
GEORGE EVANS, 132, North 5th Street, Uniform & Clothing Manufacturer,
both in the City and County of Philadelphia, State of Pennsylvania, in
U.S. America.
DAVID EVANS, Needle Manufacturer, of Studley, in the County of Warwick
I do hereby declare the nature of this invention to be as follows:-
Between the shells rearward of the hinge of an oyster or other bivalve is a space
which permits the opening of the oyster &c. It will be manifest that if the said
space is filled or occupied the opening of the shells will be prevented and the
bivalves retain their liquors and juices, so that, when opened they will be found to
be in a fresh and natural condition. In this said space I insert a plug, or its
equivalent, thus overcoming the power of the bivalve to open its shells. The
plug-preferably wedge shaped may be made of metal, hard wood, or other
material, or a mass of cement &c. may be used-is inserted in the aforesaid space
so as to sufficiently fill the same, which will prevent the opening of the shells and
the oozing or escape of the liquors or juices of the bivalves.
Dated this Seventh day of September 1891.
COMPLETE SPECIFICATION.
A New and Useful Improvement in a Mode or Method of Preserving
Oysters, Clams, and other Bivalves.
A. communication from ALBERT ALEN FREEMAN, 3321, North Broad Street, and
GEORGE EVANS, 132, North 5th Street, Uniform and Clothing Manufacturer,
both in the City and County of Philadelphia, in the State of Pennsylvania, in
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:
Between the shells rearward of the hinge of an oyster or other bivalve is a space
which permits the opening of the oyster &c. It will be manifest that if the said
space is filled or occupied the opening of the shells will be prevented and the
bivalves retain their liquors and juices, so that, when opened they will be found to
be in a fresh and natural condition. In this said space I insert a plug, or its
equivalent, thus overcoming the power of the bivalve to open its shells. The plug-
preferably wedge shaped--may be made of metal, hard wood or other material, or
a mass of cement &c. may be used-is inserted in the aforesaid space so as to
sufficiently fill the same which will prevent opening of the shells and the oozing or
escape of the liquors and juices of the bivalves.
By referring to the accompanying drawings the mode or method of this invention
will be easily & readily understood.
Fig. 1 represents a perspective view of an oyster preserved by one method
embodying this invention.
Fig. 2 represents a partial longitudinal and partial side section thereof.
Similar letters indicate corresponding parts in the two figures.

page_text: A is an oyster and B the hinge thereof. In the space at the rear of B is inserted
a plug C. This plug or its equivalent is made to fill the space at the rear of B,
so that, the bivalve will be unable to open its shells till this is removed.
It will be seen that if the space between the shells rearward or outside of the
hinge of the bivalve is utilized for the reception of means which will prevent the
opening of the same, the oozing or escape of the juices or liquors of the bivalves is
prevented, and further drawings will not be necessary to show that, if cement &c.
be used in place of the plug the end will be attained, viz. preventing the opening of
the shells.
Having now described the invention I claim-without binding myself to the 1
precise methods herein described and shown-
The preserving a bivalve by the controlling of its shells by means of a plng—or
its equivalent inserted between the shells rearward of the hinge thereof.
Dated this 10th day of May 1892.
DAVID EVANS.
