I, PHILIP JAISOHN, Physician, of 916 14th Street, N.W., in the City of
Washington, and District of Columbia, 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 relates to an improvement in cases for pocket-thermometers for
physicians' use; and it consists in the construction and arrangement of parts herein-
after described and definitely pointed out in the claims.
The aim and purpose of the invention is the provision of an improved case for
physicians' thermometers which will be adapted to receive or contain an antiseptic
material, so that the thermometer will at all times be thoroughly sterilized or
cleansed of bacteria or microscopic organisms and at the same time will be held
from contact with the antiseptic liquid or substance. Heretofore thermometer
cases have been fashioned to receive and closely hold the glass thermometers used
by physicians for taking the temperature of patients. Each time the thermometer
is used it requires thorough cleansing and sterilizing. It often happens that the
means for so cleansing are not at hand and the thermometer is placed in the case
without cleansing, the danger of which is obvious.
Primarily the aim and purpose of my invention is to so fashion a case that the
sterilizer or antiseptic agent will act on the thermometer as soon as it is placed in
the case and effectually destroy all germs or bacteria which may have been left
thereon, and at the same time prevent the antiseptic from coming in contact with
the instrument.
To this end the invention consists in the construction illustrated in the accom-
panying drawings, wherein like letters of reference indicate corresponding parts in
the several views, and in which,-
Figure 1 is an elevation of the case. Figure 2 is a vertical section.
Figure 3 is a cross-section on the line 3-3, Figure 2.
And
In the drawings, A designates the cylindrical case having the removable cap B,
of usual and well-known form. The thermometer (not shown) is adapted to closely
fit the case, but owing to its irregularity there are unoccupied spaces at the sides,
so that a free circulation may be had around the thermometer. The lower end
of the case is provided with male threads and is partly closed by a perforated
diaphragm C.

This receptacle has a closed lower end, the walls
engage the threads on the lower end of the case.

page_text: Within the receptacle-extension is placed an absorbent material E, preferably
cotton, which is saturated with an evaporable antiseptic solution, preferably
" formelin."
When the thermometer is placed in the holder and the cap secured in place, the
vapor arising from the antiseptic will penetrate all parts of the carrying-chamber
and effectually destroy all bacteria on the thermometer, rendering the same clean
and permitting its use without washing before use. Were the instrument immersed
in the liquid it would necessitate re-washing before use and thus subject the same
to the danger of further infection. Again, were the antiseptic employed poisonous
it would be an element danger and require a thorough washing after being taken
from the case. By the use of the perforated end or partition the thermometer is
held from entering the antiseptic chamber; but the fumes, which are equally as
effective for sterilizing, will pass into the case and destroy all germs on the
instrument.
It is to be understood that I do not limit myself to the construction shown and
described, for it is apparent that many changes can be made without in the least
departing from the nature and principle of my invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a physicians' thermometer case, the combination with the case proper, of
an auxiliary receptacle on the case, and a fixed partition located between the
receptacle and interior of the case, having an opening therein, whereby a communi-
cating passage is formed between the interior of the case and receptacle, and
the instrument is prevented from moving into the receptacle, substantially as
described.
2. In a physicians' thermometer case, the combination with the thermometer-
holding case and means for opening and closing the same, an auxiliary receptacle
on the case, and a fixed perforated partition between the interior of the receptacle
and interior of the case, substantially as described.
3. In a physicians' thermometer case, the combination with the case having a
fixed perforated end, of a cap for the perforated end, fashioned to constitute a
receptacle, and means for removably securing the cap on the case, substantially as
de-cribed.
4. In a physicians' thermometer, the combination with a case for the thermometer,
having a fixed perforated section, a closure for the case, and a closed receptacle
secured to the case over the perforations and communicating with the interior of
the case through the perforations, substantially as described.

of September 1893.
