pany, New Kensington, Pa., a corporation of
Pennsylvania
Application May 29, 1931, Serial No. 540,296 _'
3 Claims.
(Cl. 53-3)
The invention relates to percolator covers pro
vided with transparent tops for observing the
action of the percolators, the objects being to‘ im
prove the construction of such tops, and their
U
attachment to percolator covers, to the end that
liquid will not splash between the tops and the
walls of the top-receiving openings in the covers,
and to the further end that the tops may be in
serted through such openings from the insides
10 of the covers, and be securely attached to them.
The invention is illustrated in the accompany
ing drawing, of which Fig. 1 is a vertical central
sectional view through the upper portion of a
percolator and its cover; Fig. 2 a partial plan
H 91 view of the percolator cover; Figs. 3, 4 and 5
vertical central sectional views through the cen
tral portions of covers and tops attached to them,
illustrating modi?cations of construction; and
Fig. 6 a plan view of the modi?cation illustrated
20 in Fig. 4, showing the top as having been rotated
axially to a different position than that shown in
Fig. 4.
In the attachment of a transparent top to a
percolator cover, the usual practice is to insert
25 the top from above the cover through a top-re
ceiving opening formed in it, the dome of the
top being larger than the opening so that the top
rests upon and is supported by the margin of the
opening. Various means have been provided for
30 removably retaining tops in this position. Be
cause the tops have been thus attached, their ‘
inner ends are necessarily of smaller diameters
than the openings through which they are in
serted. As a result of this, liquid projected up
' wardly against the tops and the central portions
of the covers, sometimes objectionably splashes
between the walls of the openings and the ex—
terior of the tops. Also, because it has been nec
essary to provide considerable space for so in
serting tops, handles attached to covers and ex
tending above the tops have necessarily been
spaced substantial distances above the covers.
In the practice of this invention, a percolator
cover is provided in its central portion with an
' opening in which there is positioned an integral
transparent top, preferably formed of pressed
the top, and the wall of the cover opening through i
which it extends, are provided with interengag
ing elements which may be of various forms and
constructions.
Having reference to the embodiment of the in- 6
vention illustrated in Figs. 1 and 2, a percolator
l of conventional form is provided with a cover
having a central portion 2, and a skirt 3 ?tting
within the walls of the percolator body. The
central portion of the cover is provided with a 10
top-receiving opening ll, which, in this case, is
bounded by a yieldable ?ange 5 turned down
wardly from the metal of the cover. Within
opening 4 there is a top having a dome 5 project
ing above the plane of the opening, and a skirt 15
'|_ within the cover projecting outwardly beyond
the wall of the opening to prevent liquid from
splashing between the top and ?ange 5.
In attaching the top to the cover, it is pressed
outwardly from the interior of the cover, sprin- 20
ing ?ange 5 laterally to permit the dome of the
top to pass beyond it. Below the dome B the
top is provided with a reduced portion 8 in which
?ange 5 lies to yieldingly lock the top to the
cover.
Suitably attached to the cover there is 25
an arch-shaped handle 9, the inner edge of which
is relatively close to the top and to the cover, the
use of such a handle being made possible by the
construction and manner of attachment of the
top to the cover.

The embodiment of the invention illustrated in
Fig. 3 is the same as that shown in Figs. 1 and 2,
with the exception that the top-engaging ?ange
I ll of Fig. 3 is provided with'a plurality of notches
H which divide the ?ange into a plurality of 35
yieldable tines, and accordingly facilitate the in
sertion and removal of tops.
.
In the embodiment of the invention illustrated
in ‘Figs. 4 and 6, a top I5 is provided with one or
more lateral projections I6 which overlie the 40
margin of a ?ange l1 surrounding the top-receiv- '
ing opening. When pressing the top through the
opening, its lateral projections l6 may them
selves form grooves l8 in ?ange IT, or these
grooves may be formed in the ?ange before the 45
top is inserted. After inserting the top, it is ro
glass, having a dome projecting above the cover, tated axially to the position indicated in Fig. 6'
and having a splash-de?ecting skirt below the in which'projections l6 overlie the ungrooved
cover and projecting outwardlyvbeyond the wall portions on ?ange I1.

In each embodiment of the invention the skirt

the double function of retaining the top in the
cover when the latter is turned upside down, and
of preventing liquid from splashing between the
