The invention relates to a device for rotating
also be forced through the aperture i2, there Cl
5 thermometers for the purpose of shaking the
mercury down in the thermometer to a normal
level, and it consists in the constructions, ar
rangements and combinations herein described
and claimed.
It is a cardinal purpose of the invention to
provide a device so constructed that thermom
eters of varying diameters may be readily ac
commodated and securely held against displace
ment, especially during the “shaking down” op
1,, eration.
’
It is also an object of the invention to provide
a device in which the main body thereof may
function as a stopper for closing the mouth of a
receptacle or bottle which may be employed in
conjunction with a suitable sterilizing ?uid, for
the purpose of sterilizing the thermometer.
It is a still further object of the invention to
provide an effective seal between the thermometer
and the stopper so that leakage of the sterilizing
25 ?uid is obviated. .
Additional objects, advantages and features of
the invention reside in the construction and ar
rangement as will be apparent from the follow
ing description considered in conjunction with
30 the accompanying drawing, in which
Figure l is a side elevation of my device, illus
trating its application to a sterilizing bottle.
Figure 2 is a perspective view illustrating the
device in use.

Figure 3 is an enlarged fragmentary vertical
sectional view of the device.
Figure 4 is a top- plan view, partly in section.
Figure 5 is a view similar to Figure 3 illustrat
ing a modi?ed form of the device.
In carrying out my invention, I make use of a
40
stopper-like body ill which should be of rubber
or similar elastic material. The stopper Ill has
an axial aperture ii extending throughout the
major portion of the length of the stopper and
45 terminates in a reduced aperture l2, as clearly
shown in Figure 3.
Upon the upper face of the stopper it there is
provided an upstanding collar i3 aligned with
the aperture i2, and in practice the wall of the
59 collar l3 will be relatively thin so as to afford
the necessary ?exibility, as will be explained
hereinafter. The stopper body terminates at its
upper part in a circumscribing flange l4 thereby
providing a dished portion IS.
The aperture H is formed concentric with the
55
of.
In case a thermometer of lesser diameter is
involved, the sides of the thermometer would pass
freely through the aperture l i, but would be em
braced and securely retained in the stopper
through its engagement with the walls of the re- '
duced aperture I2. The size of the aperture ll
permits more ready insertion of the large size
thermometer than would be the case where a
single reduced aperture is involved, and also, if a
reduced aperture only was inherent through the
length of the stopper, it is quite probable that
undue distortion of the elastic body would occur,
preventing its insertion into the mouth of a
bottle.
It will thus be seen that the thermometers of
20
varying cross sectional con?gurations and diam
eters may be readily secured within the stopper,
and regardless of the diameters of the thermom
eters, in all cases, the collar 13 will adhere snug
ly to the thermometer, so that when the stopper
is inserted in a bottle neck for the purpose of
sealing the sterilizing fluid therein, liability of
seepage or leakage of fluid between the collar
I3 and the thermometer is avoided.
The stopper l0 includes a pair of oppositely
extended arms l6, integrally formed with the
stopper, each arm being of circular shape in cross
section. In order to provide an intimate and
secure connection between the arms and the body
of the stopper, I provide an anchorage H. In the
present instance, I have shown the anchorage in
the form of a light metal strip having a head
portion l3 embedded in the body of the stopper.
The strip extends from the head i8 longitudinally
(4% L1
of each arm for a suitable distance. It will of 40
course be understood that other means of anchor
age between the stopper and arms may be em
ployed.
In the modi?ed form of the device shown in
Figure 5, the stopper Ill has an axial aperture l I’
equivalent to the aperture H. The aperture ll’,
however, terminates at the upper face portion l 9
of the stopper and upon the interior surface of the
aperture H’ an annular shoulder 28 is formed.
The shoulder 20 thus defines an aperture 2! of
considerably lesser diameter than the aperture i i’
and this latter aperture will be of such size as to
receive the largest size thermometer snugly there
through and since the shoulder 28 will have ample
resilience the thermometer may also be forced 55
2,084,875
through the aperture 2!, the material of the
shoulder being compressed laterally ‘as Well as
stretched in a longitudinal direction.
In case a
thermometer of lesser diameter is involved, the
thermometer would pass freely through the aper
ture H’ but would be securely retained in the
stopper through its engagement with the walls
of the reduced aperture 2i.
In use, the device is gripped as shown in Fig
