pending stud 86 which extends through an aligned aper
ture 82 formed in the base wall 30; see FIGURE 2, and
a retaining nut 84 engages the lower threaded end of the
stud 80.
Assembly and disassembly of the various component
parts of the kettle is relatively simple. Removal of the
nut 84 will permit the base 14 to be pivoted downwardly
at the lip portion 42 and access may be had to the com
partment 23 and the heating element which will be con
tained therein. The handle 16 can be readily removed
after the nut 84 is removed by pivoting it about the leg
62 and removing the leg 62 from the slot 64.
Reassembly comprises insertion of the leg 62 in slot
64, insertion of the lip 42 in slot 26 and pivoting the base
14 onto the lower ?ange of the shell, the heating cord 56
having previously been positioned in the notch portion
44. The nut 84 is then threaded onto the lower end of
the stud 89.
Referring to FIGURES 8—12, another embodiment of
the novel kettle is indicated generally at 106 and com
prises a shell portion 112 substantially of the same char
acter as that shown in FIGURES 1_7. The shell 112 has
removably mounted on the lower edge thereof a base 114
which in this embodiment is integrally molded with a
handle 116.
The shell 112 includes a body portion 118 having a suit
ably secured bottom wall 122 and peripheral ?ange 120.
The ?ange 126 includes a forward aperture 126 cooperat
ing with the lip of a keeper element to be described.
The base 114 includes a base wall 136 including de
pending feet 132 and has embedded in the upwardly ex
as well as strain relief means for the heating element cord.
Referring to FIGURES 13-16, another embodiment,
similar to that of FIGURES 1-7, comprises a kettle in
dicated generally at 210 and includes a shell 212, a base
214 and a handle 216.
The shell 212 includes a body portion 218 having a
transverse bottom wall 222 and a lower peripheral ?ange
226 having a transverse aperture 226 extending through
a forward portion for receiving a lip portion 242 of keeper
element 238 seated in the upper edge of the vertical wall
234 of the base 214. The keeper element of this embodi
ment functions in the same manner as the keeper elements
of the previously described embodiments.
The kettle body 218 includes through the upper end
thereof a slot 264 formed by a depressed body portion 266
forming a louvre-like construction as in FIGURES 1-7.
In this embodiment, the portion 266 is directed rear
wardly, i.e., in the direction opposite that shown in FIG
URE 1.
The base 214 includes a base wall 236 integral with the
vertical wall 234; see FIGURE 15, has formed therein,
diametrically opposite keeper 238, an upwardly opening
notch 244. The lower edge of the notch 244 includes an
undercut notch portion 248 which receives an intermedi
ate portion of the electrical cord 56 therethrough. As will
be subsequently described, the notch portion 248 co
operates with a lower portion of the handle 216 to provide
strain-relief means for the cord.
The vertical wall 234 of the base has a pair of rear
wardly extending ear elements 245 which ?ank the notch
244. The ear elements 245 are transversely apertured at
247 to provide means for retaining the component parts in
assembled relation.
The handle 216 comprises an intermediate hand-grip
252 similar to those previously described, and includes an

All of the embodiments include a handle which affords‘
optimum balance and control during handling of the
kettles. Further, all of the embodiments include strain
256 conforming to the upper surface of the kettle body
218. The portion 254 has embedded therein and depend
ing therefrom a L-shaped keeper element 253 including a
leg portion 262 removably received in the slot 264.
The handle 216 includes integral with the hand-grip
portion 252 a lower angular portion 268 terminating in a
lower angular shoe or surface portion 276. The portion
276, when the kettle is assembled, will overlie notch por
tion 248 in substantially tight engagement with the cord 50 10
to prevent tension from being imposed on the cord within
the kettle. The portion 268 of the handle includes a trans
verse bore 249 which will align with apertures 247, and a
relief means for the cord, stresses are distributed over the
upper end of the handles and the surface upon which the
kettles rest will not be damaged.
The different embodiments are assembled in a relatively ‘
simple manner, thus lending to maintenance and repair
by the individual owning the kettle rather than by a spe
cialized repair man.
Although the invention has been disclosed and de
scribed with respect to hot water kettles, the novel con
struction lends itself for use on coffee pots or the like.

Considering FIGURES 17 and 18, another embodiment
is indicated generally at 310. This embodiment includes
a shell 312, a base 314, and a handle 316.
The shell 312 includes a body portion 318 identical with
that of FIGURE 1; similar parts are identified by similar
reference numerals with the pre?x 300, and the particular
portions will not be described in detail.

It will be obvious to those skilled in the art that various
changes may be made without departing from the spirit
of the invention, and therefore, the invention is not limited
to what is shown in the drawings and described in the
speci?cation, but only as indicated in the appended claims.
