Improvements in Cups for Containing Food.
We, WILLIAM HENRY PEIRSOL, Inventor, JAMES LE FEVRE PEIRSOL, Banker,
and WINFIELD SCOTT PEIRSOL, Banker, all of 220, High Street, Germantown,
Philadelphia, Pennsylvania, United States of America, 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 consists of a cup adapted to be heated and retain its heat, so
that eggs, soup, or other articles of food may be kept in hot or warm condition
therein during the use of the cup for such purposes.
In the accompanying drawing
Figure 1 represents a perspective view of a cup embodying the invention, and
Figure 2 represents a central vertical section thereof.
Similar letters of reference indicate corresponding parts in both the figures.
A designates a cup within which is suspended the concave wall B, forming the
supplemental chamber B¹ between which and the cup there is a space C to be filled
with water acting as a jacket for said wall.
In the bottom of the cup is the opening E for access to the jacket C, said open-
ing when the cup is in use, being occupied by the stopper E, the latter having
attached to it the chain or cord F for preventing loss of said stopper, said cord
being secured by a ring or bar to the base G of the cup through the opening H
therein, or in any other suitable manner.
When it is desired to use the cup the stopper is removed and the space C
filled with hot water, whereby the wall B will be heated by the same, consequently
eggs, soup or other articles of food placed in the chamber B' will be kept hot or
warm, especially during the use of the cup, it being also evident that the cup as
such, may receive the article of food in the kitchen and be carried to the dining
table or the room of an invalid, and said article will retain its heat or warmth,
as long as the water in the space C imparts the same thereto.
The cup can be washed the same as an ordinary cup, and when the stopper D
is withdrawn, the water will flow through the opening E and be discharged, the
jacket being drained as is evident.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:-
1st. A cup for the purpose set forth, having a jacket for containing water or
other fluid, for imparting heat or warmth to a wall or supplemental chamber within
said cup.
2nd. A cup having a supplemental chamber therein and a water or fluid jacket
interposed between said chamber and the cup.
3rd. A cup having a supplemental receiving chamber suspended therein, and an
opening, by which access is had to a jacket, between said cup and chamber.

page_text: 4th. A cup having a supplemental chamber suspended therein with an inter-
vening jacket, an opening in the cup leading to said jacket and a stopper for
closing said opening.
5th. A cup having a supplementary chamber suspended therein with an inter-
vening jacket, an opening in the cup leading to said jacket, a stopper for closing
said opening, and a connection for said stopper with a proper part of the cup.
