1 Claim. (01. 53-3)
This invention relates to a novel accessory in
the form of an attachment cooperable with the
lid and glass top of a percolator and expressly
designed to serve as a means for maintaining
5 said glass top against accidental displacement.
By way of introduction it is to be pointed out
that in the majority of constructions the cap
like glass top of a percolator is generally pro
vided with a rim having diametrically opposed
10 projections which serve to hold the glass top in
place after it is inserted in lid and turned slight
ly. In most instances the lid is formed With a
central opening having a depending annular
?ange equipped with diametrically opposite
15 clearance notches to accommodate the projec
tions whereby to permit the projections to be
held in place by the ?ange. It is a matter of
common knowledge, however, that wear and tear
of these parts soon permits rotary shifting of
20 the glass top and it is frequently displaced, re
sulting in breakage and other damage.
The purpose of the present invention is to
provide a resilient wire device in the nature of
a clip which can be attached to the button-like
25 projections on the glass top and which coop
erates with the ?ange in a more satisfactory
manner to satisfactorily hold the glass top in
place and against accidental displacement.
Other features and advantages will become
more readily apparent from the following de
scription and drawings.
In the drawings:—
Figure 1 is an elevational view of the wire re
taining device or clip showing the manner in
35 which it is associated with the glass top and
hinged lid of a percolator.
Figure 2 is a bottom plan view of the struc
tural assemblage depicted in Figure 1, the sec
tion being on the plane of the line 2—-2 of Fig
ure 1.
Figure 3 is a vertical sectional view taken ap
proximately on the plane of the line '3——3 of
Figure 1.
Figure 4 is a section on the vertical line 4—4
45 of Figure 1.
Figure 5 is a perspective view of the wire from
which the retaining clip is bent or fashioned.
Figure 6 is a perspective view of the retainer
or clip per se.
Referring now to the drawings by distinguish
ing reference characters I call attention ?rst to
Figure 1 wherein the percolator is denoted by
the numeral 1 and the hinged lid is indicated at
8. The glass top, which is conventional, is de
55 noted by the numeral 9. The customary rim
ID at the bottom of this glass top is formed with
the usual diametrically opposed button-like pro
jections H. Under ordinary circumstances
these are adapted to be placed through the clear
ance notches I2 formed at diametrically oppo
site points in the depending circular ?ange I3
carried by the lid. That is to say, the rim [0
?ts telescopically down through the opening and
against the ?ange, the projections of keepers ll
being placed through the notches I2 and then
turned so as to be held against the lower edge
of the ?ange. As before stated, however, these
parts frequently become loose and this results
in a recurring displacement of the glass top.
Therefore, I have evolved and produced requi 15
site simple and economical means to guard
against such accidental displacement of the
glass top. This means may be described broad
ly as a retainer and it is in the form of a resili
ent Wire clip M of the type shown in Figure 6.
This clip may be formed from a single length
of wire l5 (see Figure 5). It is bent between
its ends to form a coil spring as at I6 and to
further provide a pair of duplicate adapter
arms or branches I'I. These terminate in up
bent eyes l8 which are adapted to snap over
the projections H (see Figure 4) so that the
eyes themselves will serve as retaining elements
and engage beneath the edges of the ?ange as
shown in Figure 4 to prevent displacement of
the glass top. It is obvious that the wire must
be non-corrosive and su?iciently resilient to en
able it to be conveniently snapped into place
and con?ned primarily within the limitsof the
glass top itself.
It is evident from the foregoing description
that the novelty and invention resides only in the
attachment or retaining clip illustrated in Figure
Fundamentally this comprises retaining ele
ments l8 to resiliently snap on and surround the 40
stock lugs on the glass top whereby to- permit
these pieces l8 to serve as check elements or
stops for holding the glass top- in place. Stated
otherwise the principal novelty is in the features
l8 with some means for attaching them together
resiliently and holding them on the lugs so that
they merely enlarge the lugs and provide a more
satisfactory means of avoiding displacement of
the glass top if and when the lugs or ?ange are
spread or become worn.
Thus it will be seen 50
that novelty resides in these stop- elements I8
which embrace the lugs and which are attached
together through the instrumentality of resilient
arms I‘! forming a connective element and which 55'
arms themselves are preferably associated with
a spring or coil I6.
tion claimed may be resorted to in actual prac
tice, if desired.
In practice the device is simply snapped on
to the lugs after the glass cap is in place and this
What is claimed is:—
As a new article of manufacture, a retaining
is done by swinging the lid 8 to open position.
It is thought that persons skilled in the art to
which the invention relates will be able to obtain

wire provided at opposite ends with loops fash
ioned to embrace existing lugs on the percolator
