Year: 1875

page_text: LETTERS PATENT to William Phillips Thompson, of 6, Lord Street,
Liverpool, in the County of Lancaster, Consulting Engineer and
Patent Agent, for the Invention of "IMPROVEMENTS IN PRESERVING
FOOD AND OTHER PERISHABLE ARTICLES AND IN APPARATUS OR APPLIANCES
THEREFOR."-A communication from abroad by E. Leuchtenrath,
of Paris, in the Republic of France.
Sealed the 23rd May 1876, and dated the 26th November 1875.
PROVISIONAL SPECIFICATION left by the said William Phillips
Thompson at the Office of the Commissioners of Patents, with his
Petition, on the 26th November 1875.
I, WILLIAM PHILLIPS THOMPSON, of 6, Lord Street, Liverpool, in
the County of Lancaster, Consulting Engineer and Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PRESERVING FOOD AND OTHER PERISHABLE ARTICLES AND IN APPARATUS OR
APPLIANCES THEREFOR," a communication to me from abroad by E.
Truchtenrath, of Paris, in the Republic of France, to be as follows:-
It consists,―

page_text: a glass jar having a projecting ledge inside the neck and the neck itself
above the ledge projecting inwards, thus forming a sort of groove or
under cut all round in the neck. The lid of the jar (also of glass) fits
loosely in the neck, and the upper surface of said lid is bevelled round
the edge to approximate in shape to the groove.
2nd. I place a perforation in the centre of the lid to let out steam
and to prevent it being stopped up by the articles to be preserved
pressing into it. I construct on the under side of the lid a rim
surrounding the hole, and at some distance from it, and spring a piece
of wire gauze into the groove formed by the ring and the lid, the ring 1
being slightly undercut for this purpose. The gauze being dished out
prevents the meat, etcetera, from being forced up into the hole.
3rd. In using the apparatus after inserting the meats I put on the
lid and pour plaster of Paris into the groove between the lid and the
rim of the jar, and when this has consolidated I boil the jar in a chloride 1
of calcium or water bath of any of the ordinary well known kinds used
by meat preservers. When the air is entirely eliminated I remove the
jar from the fire and stop up the central vent with plaster of Paris.
As plaster of Paris is porous I paint it over with a solution of alum
and saltpetre, drying oil, paraphene, water glass, or other material for 2
stopping up the pores.
E
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Phillips Thompson in the Great Seal
Patent Office on the 24th May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 2
PHILLIPS THOMPSON, of 6, Lord Street, Liverpool, in the County of

•

page_text: Her special licence that I, the said William Phillips Thompson, my

munication from E. Leuchtenrath, of Paris, in the Republic of France),
upon the condition (amongst others) that I, the said William Phillips
executors or administrators, by an instrument in

tained in and by the following statement, reference being had to the

marked thereon.
First. In substituting for the tins so generally used for packing meats
a glass or vitrified earthenware jar A having a projecting ledge B inside
the neck C, and the neck C itself above the ledge projecting inwards,
thus forming a sort of groove D or undercut all round in the neck. The
lid E of the jar of glass, earthenware, or other suitable material fits
loosely in the neck, and the upper surface of said lid is bevelled round
the edge to approximate in shape to the groove.
2nd. I place a perforation G preferably in the handle or knob in the
centre of the lid to let out steam and to prevent it being stopped up by
the articles to be preserved pressing into it. I construct on the under
side of a rim F surrounding the hole and at some distance from
it, and spring a piece of wire gauze H into the groove formed by tho
