APPARATUS FOR PRESERVING YEAST."

the Commissioners of Patents on the 24th June 1878.

APPARATUS FOR PRESERVING YEAST."
"IMPROVEMENTS IN
The object of the Invention is to provide means to enable yeast to be kept in a
warm atmosphere without such injurious effect on its quality as is now frequently
the case with the methods at present in use. For this purpose I make of sheet
metal a circular casing open at the top. I place within the interior of the same
a smaller casing of similar construction in such manner as to leave a vacant space
between the inner circumference and bottom of the larger casing and the outer
circumference and bottom of the smaller one, this latter being furnished with pro-
jecting pieces on its outer circumference and bottom for the purpose of maintaining
it in its proper position in regard to the larger casing. I then fill in the vacant
space between the two casings with fossil earth, chalk, sawdust, or any suitable
non-conducting substance. When in its proper position the upper edge of the inner
casing is a little lower than that of the outer one, say, about half an inch in the
case of casings about one foot high and six inches in diameter.
Round the annular filled-in space between the upper edge of the inner casing
and the interior circumference of the outer one I attach a metal cover, hermetically
and permanently sealing such annular space.
At the upper part of the interior of the larger casing I insert and fix a metal
ring provided with a female screw screwing in the cover, so as to render the
casing air-tight. This being done, the yeast intended for preservation is placed

preventing the admission of air to the yeast; the penetration of warinth being
prevented by the annular space filled in with a non-conductor of heat, as before
mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Love in the Great Scal Patent Office on the 24th December

"IMPROVEMENTS IN
The object of the Invention is to provide means to enable yeast to be kept in a
warm atmosphere without such injurious effect on its quality as is now frequently
the case with the methods at present in use. For this purpose I make of sheet
metal a circular casing, open at the top place within the interior of the same a
smaller casing of similar construction in such manner as to leave a vacant space
between the inner circumference and bottom of the smaller one, this latter being
furnished with projecting pieces on its outer circumference and bottom for the
purpose of maintaining it in it: proper position in regard to the larger casing.
I then fill in the vacant space between the two casings with fossil earth, chalk,
sawdust, or any suitable non-conducting substance. When in its proper position
the upper edge of the inner casing is a little lower than that of the outer one, say,
about half an inch, in the case of casings about one foot high and six inches in
diameter.
Round filled in space, between the upper edge of the inner casing and the interior
circumference of the outer one, I attach a metal cover, hermetically and per-
manently scaling such annular space.
At the upper part of the interior of the larger casing I insert and fix a metal
ring provided with a female screw for screwing in the cover, so as to render the
casing air-tight. This being done, the yeast intended for preservation is placed
within the interior casing, and the cover then screwed into the outer one, thus
preventing the admission of air to the yeast, the penetration of warmth being
prevented by the annular space filled-in with a non-conductor of heat, as before
mentioned.
Having now described the nature of my Invention, and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself to
the precise details herein-before described, as the same may be varied without
departing from the nature or principle of my said Invention; what I claim as my
Invention is, the apparatus for preserving yeast, substantially as herein described.
In witness whereof, I, the said Henry Love, have hereunto set my hand and
seal, this 24th day of December, in the year of our Lord One thousand eight
hundred and seventy-eight.
