4 Claims. (Cl. 4-187)
This invention relates to a counterline appliance and
mounting means therefor, and more especially to an v
varrangement for fastening such an appliance in 'position
within an opening therefor in a countertop.
The present invention constitutes a continuation-in-part
of our copending patent application, Serial No. 710,735,
filed January 23, 1958, now abandoned, in which one such
appliance was disclosed. In contrast therewith', this ap
plication considers the more general subject of mounting
and fastening a variety of counterline> appliances _in a
esign so that such appliance may be mounted with facility
in an opening therefor provided along a countertop While
establishing a liquid-tight seal with the countertop.
An- .
other object of the invention is in the provision of an
integral rim appliance and fastening arrangement therefor,
wherein the fasteners are quickly and easily interchanged
when necessary, and wherein the number of fasteners
required for any installation may be determined on the
job, whereby an effective liquid-tight seal can be estab
lished between the countertop and appliance throughout
the entire perimetric length of the latter.
Still another object is that of providing in combination
with an appliance having a generally planar marginal
flange or edge portion adapted sealingly to engage the
upper surface of a countertop, a fastener arrangement
including a mounting element carried by such flange along
the undersurface thereof and a plurality of fasteners ad
justably carried by the mounting element for selective

fastening the same in position along a countertop. How
ever, with regard to the class of appliances considered
herein, each such appliance seats within an opening pro
vided therefor in the countertop, and may be character
ized as being of generally sheet-like or planar form in that
it has a perimetric rim or ilange that rests upon the upper
surface of the countertop. It should be noted that in. this
general classification, integral rim appliances (often re
ferred to in the industry as “self-rimmed,” especially in
connection with sinks Where the term “self-rimmed bow ”
is also used) have posed heretofore a diñicult mounting
problem in that fixed fasteners or clamps are carried
thereby, and if one or more of such fasteners breaks olf,
is stripped, or otherwise becomes ineffective, the entire
n
A further object of the invention is to provide fastener
apparatus for securing the rim of an appliance to a
' countertop, in which the force application developed by
each of the fasteners is effectively utilized and appears
between the rim and countertop to clamp the rim thereto,
and is not >dissipated by needless application of a sub
stantial portion thereof to thel rim. Still another object
is in the provision of a rim-equipped appliance and fas
tener apparatus therefor, in which the fastener apparatus
comprises an elongated mounting element that is secured
to and extends along the underside of the rim inwardly
of the outer edge thereof for dependency into the opening
of a countertop, in which fastener elements are movable
to selected locations along the length of the mounting
element and can be removed therefrom and inserted there
into with ease, and in which a clip or clamping element is `

thereof cannot be drawn tightly against the countertop

at all locations to establish the necessary liquid-tight seal
therewith. In contrast thereto, this diiiiculty does not
occur with separate rim appliances, for »the fasteners are
carried by the separate rim which is readily replaced.
'
Yet a lfurther object is that of providing clamping ap
paratus of the type described, in which the fastener ele
ment has an elongated shank, and in which the clip or
clamping element engages the shank at two axially spaced
locations therealong--one such location being along the

However, if reference is made to FIGURE l, it will be
