of Kent, Surgeon for an Invention of A NEW OR IMPROVED METHOD OF
AND APPARATUS FOR RETAINING HEAT IN INFANTS' FEEDING BOTTLES, ALSO
APPLICABLE FOR PRESERVING ICE AND OTHER PURPOSES
"
PROVISIONAL SPECIFICATION left by the said Charles Pierce Downey
Chittenden at the Office of the Commissioners of Patents on the 16th June
1882.
CHARLES PIERCE DOWNEY CHITTENDEN of Lee in the County of Kent, Surgeon
"A NEW OR IMPROVED METHOD OF AND APPARATUS FOR RETAINING HEAT IN
INFANTS' FEEDING BOTTLES, ALSO APPLICABLE FOR PRESERVING ICE AND OTHER
PURPOSES
"
My Invention relates to a new or improved method of and apparatus for
retaining the heat of milk in infants' feeding bottles or of any other fluid
contained in similar or other shaped receptacles, such apparatus being also applicable
for preserving ice.
My Invention consists in the use of an inner box or case made of wood, metal,
or other suitable material and placed within an outer box or case of similar
material. Between the inner and outer cases or boxes is packed slag or lag felt or
silicate of cotton or any other suitable non-conducting substance and into the
inner box or case is placed the feeding bottle (or other vessel) wrapped in felt
and containing the milk (or other fluid) to be kept hot. The whole is closed
by a hollow lid also packed with felt or other nonconducting material, a strip of
India rubber or other packing material being placed between the lid and boxes or
cases.
By this arrangement owing to the non-conducting nature of the felt or silicate of
cotton the heat of the liquid contained in the feeding bottle or other vessel is
retained.
When my apparatus is used for preserving ice the feeding bottle or vessel is
removed and the ice placed directly into the inner box or case.

CHARLES PIERCE DOWNEY CHITTENDEN of Lee, in the County of Kent, Surgeon
"A NEW OR IMPROVED METHOD OF AND APPARATUS FOR RETAINING HEAT IN
INFANTS' FEEDING BOTTLES, ALSO APPLICABLE FOR PRESERVING ICE, AND OTHER
PURPOSES
"
My Invention relates to a new or improved method of and apparatus for
retaining the heat of milk in infants' feeding bottles or of any other fluid
contained in similar or other shaped receptacles, such apparatus being also applicable
for preserving ice.
My Invention consists in the use of an inner box or case made of wood, metal,
or other suitable material-and placed within an outer box or case of similar
material Between the inner and outer cases or boxes is packed slag or lag felt or
silicate of cotton or any other suitable non-conducting substance and into the inner
box or case is placed the feeding bottle (or other vessel) wrapped in felt and
containing the milk (or other fluid) to be kept hot. The whole is closed by a
hollow lid also packed with felt or other non-conducting material, a strip of
India rubber or other packing material being placed between the lid and boxes or
cases.
And in order that my said Invention may be well understood I shall now
proceed particularly to describe the same, reference being made to the accom-
panying sheet of drawings, like letters of reference indicating corresponding parts
in all the figures.
Figure 1 is a vertical section of my improved heat retaining apparatus, and
Figure 2 a sectional plan thereof.
A represents a square, rectangular, or other shaped box or case made of tin
(as shewn), wood, metal, or other suitable material and placed within an outer box
or case B of similar shape and material, a space being left between the boxes or
cases A and B into which space is packed compressed hair C, silicate of cotton, or
any other suitable non-conducting substance, the space is closed at the top by a
ring or disc D of wood or other non-conducting material. Into the inner box
or case A is placed the feeding bottle E (or other vessel) wrapped (or not) in felt,
leather, or other non-conducting material and containing the milk (or other fluid)
to be kept hot. The whole is closed by a hollow or box shaped lid F packed with
compressed hair or other non-conducting material C¹, which is faced with and
confined to the lid F by a sheet or lining of India rubber or other suitable cloth G.
The sides and bottoms of the inner and outer boxes or cases A and B may be lined
or coated with asbestos, lamp black, or India rubber solution. By this arrangement
(owing to the non-conducting nature of the hair or other packing used) on tightly
closing the lid F upon the upper ring or disc D and securing it in this position by
a spring or other fastening the heat of the liquid contained in the feeding bottle
or other vessel is retained for a great length of time and all the trouble and
annoyance incidental to other modes of effecting the same object are thereby
avoided.
My Invention may also be used for retaining cold such as for preserving
provisions in hot weather, and when used for preserving ice I draw off any
drainage water from the inner box or case A by a tap or cock H which is fitted
into a tube I made of vulcanite or other suitable non-conducting material and
uniting the inner and outer cases A and B as shewn. When not so used the tap
or cock H may be removed and a plug substituted.

page_text: Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider novel and original and
therefore claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is :-
1. The combination and use of an inner box or case A with an outer box or
case B, non-conducting packing C, and closing ring or disc D, substantially as
and for the purposes hereinbefore described and shown by the accompanying
drawing.
2. The combination and use of a hollow or box shaped lid F nonconducting
packing C and cloth or lining G with the inner box or case A, outer box or case B,
and closing ring or disc D, substantially as and for the purposes herein before
described and illustrated on the accompanying drawing.
In Witness Whereof I the said Charles Pierce Downey Chittenden have
hereunto set my hand and seal this eleventh day of December in the year
of our Lord One thousand eight hundred and eighty two.
