4 Claims. (Cl. 40-154)
Our present invention relates broadly to picture fram
11 of the mat proper, to the inner corner 12 of the open
ing of each said mat 7, thereby covering the matched joint
formed by the assembly of the four mat-board strips.
The end portion of these clips 10 are cut to a 45 degree
angle, see numeral 13 and said clips are obviously of
such length so‘as to coincide with the exact length of the
mating edges of the joint 14 thereby covering said joint
ing materials and more particularly to a method of mak
ing mats for use in the mounting or framing of works 10 in its entirety.
The clips 10 are of unitary construction having a thin
of art such as paintings, drawings, photographs and the
longitudinally disposed central divider 15 for holding
like.
The principal object of this invention is to permit the
use of strips of cardboard or mat-board cut to proper
length and width thus eliminating the necessity of hand
cutting a mat from a sheet of cardboard or mat~board.
A further object of this invention is to provide pre-cut
means for forming a mat for the mounting of pictures,
drawings, photographs, and the like works of art.
A further object of this invention is to provide pre-cut 720

It will be understood that the sections 16 of the clips 10 are
necessarily spaced apart according to the thickness of the
mat-board material, however, this is now generally stand
ardized with respect to the art of framing and mounting
of works of art and the like.
