the appended claims.
FIG. 1 illustrates a toy “percolator” device 10 which
includes an open-topped pot or container .12 formed by
side wall 14 and bottom wall 16. The removable lid
18 is formed with horizontal ?ange 20 and vertical flange
22 around its outer edge so as to generally conform to

utilitarian operations and devices. Similarly, toys which
it is held against undesired dislodging by bubbling im
can teach children how to put together or operate com
mon household appliances in a neat and orderly man 40 pact of water from below by gravity alone; or alternative
ner, while being sufficiently realistic and interesting to
hold the children’s attention, are known to be popular
and desirable, particularly with parents. Like all simula
tor training devices, they do, in a sense, have an educa
tional value.
Further, toys or devices which not only 45
simulate functional operations, but which also actually
produce pleasing or desired results in addition to amuse
ment or educational values, are particularly desirable.
It is an object of this invention to provide safe, in
expensive, and durable devices having these amusement,
educational and utilitarian values. It is a further object
of this invention to provide toys which simulate the
bubbling or “percolating” operations of household ap—
pliances. Another object of this invention is to provide
a toy which realistically simulates the appearance and 55
operation of a common “percolator” cotl‘eepot without
the application of heat or boiling, and which is also
capable of preparing and producing ?avored and/or
colored drinks. Other objects and advantages of the
invention will be more fully apparent from the remainder 60
of this description, including the appended claims and
the accompanying drawings in which:
FIG. 1 is a vertical section of a toy device according
to the invention;
P16. 2 is a cross-sectional view taken at line 2—2 of 65
FIG. 1;
FIG. 3 is a cross-sectional view taken at line 3—3 of
FIG. 1; and
ly ?anges 20 and 22 may be formed to conform closely
to the cross-sectional shape of side wall 14 so as to provide
a “tight” ?t which further secures the lid 18 against such
dislodgement. Also, other means for covering or closing
the open top of the container 12, such as hinged lids, or
caps may be used in place of the lid 18.
The lid 18 is desirably formed with the domed shape
illustrated in FIG. 1, and includes transparent top wall
section or member 24, joined to lid 18 around the center
of the complete lid 18. The lid 18 and the container
12 may be formed of metal, plastics, glass or other ma
terial; the transparent top wall member 24 of the lid 18
is formed of glass or transparent plastic, although alter
natively the entire lid 18 may be formed of such trans
parent materials, as may the container 12 and almost all
the remaining structure of the device it). The transparent
top wall member 24, if not an integral part of the lid
18, may be either ?xedly or removably joined to the re
mainder of the lid 13 by conventional joint means 26.
A spout or means 23 for pouring liquid out of the con
tainer 12 is preferably formed in side wall 14. The com
plete toy device ltl also desirably includes hollow handle
means 30 for holding the toy device 10, mounted at its
upper end 31 on the exterior of side wall 14 and at its
lower end 33 on the exterior of base wall 32. Base wall
32, which may comprise an extension of side wall 14,
is mounted on container 12 so as to be capable of sup
porting the container 12 and so as to enclose an open

of the base portion 86 rests on top of the base 76 of

of member 70 is continuously joined to side wall 14 along
its edges so as to form, with side wall 14, a pipe or
conduit communicating with the hollow interior of the
handle 30. The base 76 of the member 70 is similarly
formed with arcuate cross-section and joined along its
of member 70 to the level of liquid within the con
tainer. However, since the conduit means 64 communi

is generally circular in cross section, extends upwardly
and electric motor 52, the electric motor 52 operates and
‘from the center of bottom wall 16 of the container 12; 75 drives the compressor 58, thereby forcing air through
outlet port 62 and conduit means ‘64. This forces the
liquid in conduit means 64 into the mixing chamber 90
formed by the domed base portion 86 of tube member
84. As the liquid is forced out the top end 80 of the
conduit means 64 some will escape downwardly through
the base portion 86 of the tube member 84 and out be
tween the lugs 92, but because of its direction of ?ow
and the shape of the base portion 86, the bulk of it will
be forced up the upper tube portion 83 of tube mem
ber 84. After all the water has been forced out of con 10
duit means 64, the air forced out the top end 80 of con
duit means 64 will constantly mix with water forced by
hydrostatic pressure into the mixing chamber 90 and in
a “bubbling” action the mixed air and water will be forced
up the tube member 841 and will bubble out the open
top end 94 of tube member 84 in an action very similar
in appearance to the “percolating” of a common house
hold coffeepot. The water bubbling out the top end 94
of tube member 84 then falls down into the ?lter holder
96, where it mixes with and drains through the ?avoring
and/or coloring additive materials in the ?lter holder 96,
and then passes through the perforations 98 in the ?lter
holder Q6 and falls back into the main body of liquid
within the container 12. No heating or boiling is neces~
sary to achieve this operation, although of course pre
heated liquid may be used in operation of the invention,
or ice cubes placed in the ?lter holder 96 or the main
body of liquid within the container to obtain hot or cold
drinks. Other heating or cooling means associated with
