Appeal No. 97-0675
Application No. 08/389,684
OPINION
The appellant’s invention is directed to inserting
picture hangers into picture backings. On pages 1 and 2 of
the specification, the appellant explains that in the prior
art the hangers have been made in strips, with the prongs by
which they are attached to the picture backings being formed
by a punching operation, after which the prongs are oriented
in the desired direction and the individual hangers are
severed from the strip. Installation on the picture backing
was accomplished manually by means of a hammer or a press. In
the present invention, the punched strips are fed into an
apparatus comprising means for advancing the strip and an
anvil means movable in a direction generally perpendicular to
the strip. The anvil means presses the hangers into the
picture backing. Attached to and moving with the anvil means
are means for pressing the hanger into the picture backing,
means for severing the first blank from the strip, and means
for orienting the prongs. Each cycle of movement of the anvil
causes three functions to take place: (1) the finished hanger
positioned beneath the anvil is severed from the strip; (2)
the severed finished hanger is pressed into the picture
