This invention relates- to a functionally and unite, against the probability of any accidental
detachment, a plurality of layers of material for
ployed in numerous different associations but ' the purpose of covering an opening in one of
which is primarily intended to couple layers of such layers or otherwise, but which coupling at
5 metal or similar material against movement with the same time may, with equal facility be manip- 5
respectto each other, and/or to close or cover -ulated to’allow of the parts being readily de
structurally improved coupling which may be em
- tached. -The uses to which a structure such as
openings in one or more of such layers.
It is an object of the invention to furnish a
unit of this character which may readily be
10 ‘manipulated to secure any number of materialA
layers one to the other and against any probability
of accidental displacement with respect to each
other.
A further object of the invention is that of fur- '
15 nishing a coupling device, the parts of which
willfunction lto permit of aready release of the
layers from each other, it being understood that
the coupling and uncoupling of the parts as speci
fled in this and »preceding paragraphs may be
0 achieved, for example, merely by the employment
_of a simple tool such as a screw driver.
An additional object is that of providing a
coupling device embodying relatively few parts.
each individually simple and rugged in construc
25 tion, such parts being capable of manufacture by
> more or less automatic machinery and when as
sembled operating over long periods of time with
freedom from all diillculties.
With these and other objects in mind, reference

that the same form a part of a plate i3, secured 25
