DEMONST‘RATING APPARATUS

Calumet Refining Company, Chicago, Ill., a cor
poration of Illinois
Application December 21, 1936, Serial No. 116,978
10 Claims.
This invention relates to an apparatus for dem~
onstrating the fluidity of oils or the like.
One important characteristic of certain oils,
such as motor oils for winter use, is the ability
` 5 of the oil to flow freely at low temperatures, and
one object of the present invention is to provide
an apparatus whereby the fluidity of an oil, or
other liquid, at low temperatures may be dem
onstrated to prospective purchasers or to other
interested parties.
A further object of the invention is to provide
such an apparatus which will be simple in con
struction and operation and can be easily manip
ulated to effect the demonstration.
Other objects of the invention may appear as
the apparatus is described in detail.
In the accompanying drawing Fig. 1 is a verti
cal section taken centrally through the appa
ratus with the supporting stand partly broken
20 away; Fig` 2 is a section taken on the line 2_2
of Fig. 1, looking in the direction of the arrows
and partly broken away; and Fig. 3 is a side ele
vation of the apparatus with the supporting stand
partly broken away.

In the drawing I have illustrated one embodi
' ment of my invention and have shown the same
as comprising an outer receptacle within kwhich
is mounted a smaller container for the oil or
other liquid, the fluidity of which is to be dem
onstrated. The receptacle and the container
have alined transparent portions to permit the
action of the oil to be observed from the exterior
of the receptacle. The receptacle is adapted to
receive a suitable refrigerant, such as dry ice,
_ which will lower the temperature of the oil in
the container and thus enable its action at low
temperatures to be observed.
In the particular embodiment here illustrated
the apparatus comprises an outer receptacle 5
40 formed wholly or in part of glass or other trans
parent material. As here shown this receptacle
is in the form of a glass jar having its upper end
open, the open end of the jar being slightly re
duced in diameter to provide a neck 6. This open
end of the jar may be closed in any suitable man
ner and, as here shown, it is provided with a re
movable cap 'I which fits over the upper end of
the jar and, if desired, a gasket 8 may be inter
posed between the cap and the edge of the neck 6.
Various means may be provided for securing the
cap in place, that here illustrated comprising a
cross bar 9 the ends of which project beyond the
jar and are provided with openings to receive
clamping screws IIl which are pivotally mounted
at their lower ends on a metal ring II extending
about and rigidly secured to the neck of the jar.
Wing nuts I2 on _the upper ends of the screws
enable the bar to be clamped tightly against the
closure.
One or more upright partitions are arranged
60
within the receptacle 5 to divide the interior
thereof into two or more compartments. `In the
form here illustrated there are two partitions I3
spaced one from the other and from the respec
tive sides of the receptacle and connected one
to the other at their upper and lower edges by a
top member I4 and a bottom member I5, thus
forming a housing the lateral ends of which are
open adjacent to the transparent wall of the re
ceptacle. 'I'he partitions are of such width that l0
the housing can be inserted through the neck of
the jarv and are preferably of a widthapproxi
mately equal to the width of the neck so that
when the housing is in position in the receptacle
the partitions will be supported in chordwise re
lation thereto, as shown in Fig. 2.
Mounted in the compartment formed between
the partitionsl3, which `constitute the side walls
of the‘housing, is a container25 for the oil or
other fluid to be demonstrated, and this con
tainer is formed either partly or wholly of glass `
or other transparent material so that the con
tents of the container may be viewed from the
exterior of the receptacle and the container may
be tilted in any suitable manner so that the flow
ofthe oil, which does not completely ñll the con
tainer, may be observed. In the present instance
the container is mounted in a fixed position be
tween the partitions and is tilted by tilting the
receptacle. As here shown, it is of a vertical 30
length approximately equal to the height of the
housing and the top member III of the housing is
provided with an opening Iii in line with the con
tainer. The upper end of the container is closed
by a stopper, such as a cork I1, which extends up
wardly through the opening I6 and thus anchors
the container to the housing.
The container, partly ñlled with oil, is placed
Within the housing, the stopper I'I inserted and
the housing and container then placed within 40
the receptacle. A suitable refrigerant, such as
dry ice, is then placed in the spaces or compart
ments formed between the partitions I3 and the
`respective sides of the receptacle. Thus the re
frigerant quickly lowers the temperature of the 45
oil and‘by manipulating the apparatus the oil
can be caused to flow within the container and
`its ñuidity` observed. If desired, a thermometer
I8 may be inserted through the stopper I'I into
the oil and supported with its upper end pro
jecting above the receptacle so that the actual
temperature of the oil may be determined.
The receptacle and its contents are preferably
supported for pivotal movement so that both
the receptacle and the container may be tilted ..55
and, in the present instance, the receptacle is
mounted between the side members `ZIJ of a suit-`
able stand and is pivotally supported on that
stand by pivot pins 2| carried by upwardly ex
tending lugs 22 secured to the ring II. `By so ar

a housing in said receptacle having upright side
may be freely moved about its axis to any de
Wallsspaced one from .the other and from the
'._wall lof said receptacle, a top member connect
ing the upper edges of said side walls and having
an opening, an upright transparent container for
liquid arranged in said housing with its open
sired extent.
The sidefmembersiZO-¿are.prefer
ably foldable so that the apparatus as a whole
may be packed in a small space and to this end
each side member is formed in two partsv pivot
ally connected one to the other at'23.
The operation of the apparatus'will be'readily

understood from the foregoing descriptionand
`through said opening to retain said container
it will be apparent that any desired oil or other
liquid may be placed in thecOntainer and its
in. an uprightposition, the wall of said receptacle
having transparent portions in line with the re
spective ends of the space between said side walls,
and a thermometer extending through said clo
sure into the liquid in said container and pro 15
temperature reduced to the desired degree. By
then tilting the apparatus the fluidity-of the oil
>at this low temperature may be ascertained by
observing’its iiow, through thetransparent walls
of the receptacle and the container.

ment of my invention I wish it to be ’understood
-that I do not desire to` be limited' to "thede
tails thereof as various modifications may occur
to a person skilled inthe art.
