PROVISIONAL SPECIFICATION.
Improvements in Cases for Clinical Thermometers and other
Articles.
I SAMUEL GEORGE DENTON of 25ª Hatton Garden in the County of Middlesex
Surgical Instrument Maker do hereby declare the nature of this invention to be as
follows:-
My invention simplifies the taking off and putting on of the lids of Cases for
Clinical Thermometers and other articles for which tube shaped cases are used.
Round the inside of the lower end of the lid of the case I stamp out a groove and
in a corresponding position on the body of the Case I press out or affix a pin or knob.
On each side of this pin or knob I cut a slot longitudinally right through the tubing,
the effect of which is to cause the pin or knob to act like a spring.
To close the case the lid is placed over the mouth in the usual manner and is
pressed down until the groove in the lid reaches the pin or knob on the body of the
case when the pressure on the slotted portion of the lid, caused by the protruding
of the pin or knob, is released and the groove falls over the pin or knob-securely
closing and fastening the Case. The lid is easily and instantly removed by merely
pulling it off.
•
When desired two or more pins or knobs may be used on the Case-the longitu-
dinal slots always being cut on both sides of each pin or knob. The groove being
made so as to entirely encircle the lid no guides or other additions are necessary to
keep the pins or knobs in any particular position.
To apply my invention to reversible Cases for Clinical Thermometers I make two
grooves on the outside of the lid (into which lid the Clinical Thermometer is cemented
or otherwise affixed at its stem end)-the grooves being at corresponding positions
from the open and closed ends of the lid respectively and the pins or knobs on the
Case are fixed or pressed inwardly. These variations are necessary as in reversible
Cases the lid fits into instead of over the mouth of the Case.
The same variations are required in applying my invention to reversible pen and
pencil cases and similar articles.

1 SAMUEL GEORGE DENTON of 25" Hatton Garden in the County of Middlesex
Surgical Instrument Maker 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 :-
My invention simplifies the taking off & putting on of the lids of cases for
Clinical Thermometers & other articles for which tubed-shaped cases are used. Round
the inside of the lower end of the lid of the case I stamp out a groove & in a corre-
sponding position on the body of the case I press out or affix a pin or knob. On
each side of this pin or knob I cut a slot longitudinally right through the tubing, the
effect of which is to cause the pin or knob to act like a spring. To close the case the
lid is placed over the mouth in the usual manner & is pressed down until the groove
in the lid reaches the pin or knob on the body of the case when the pressure on the
slotted portion of the case caused by the protruding of the pin or knob is released &
D

page_text: the groove falls over the pin or knob securely closing & fastening the case. The lid
is easily & instantly removed by merely pulling it off. When desired two or more
pins or knobs may be used on the case, the longitudinal slots always being cut on
both sides of each pin or knob. The groove being made so as to entirely encircle
the lid no guides or other additions are necessary to keep the pins or knobs in any
particular position.
To apply my invention to "reversible" cases for Clinical Thermometers, I make
two grooves on the outside of the lid (into which lid the Clinical Thermometer is
cemented or otherwise affixed at it's stem end) the grooves being at corresponding
positions from the open & closed ends of the lid respectively & the pins or knobs on
the case are fixed or pressed inwardly. These variations are necessary, as in
"reversible cases the lid fits into, instead of over the mouth of the case.
The same variations are required in applying my invention to "reversible" pen &
pencil cases & similar articles.
In reference to the drawing herewith annexed A represents the stamped out
groove B the pressed out pin or knob & C the longitudinal slots.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
Constructing pull off cases with a spring or catch which spring or catch forms
part of the case itself.
