Pliers with modified jaws for use in auto body repair

A pair of pliers have two opposed jaws. The first jaw has an inner working surface with two flat sections that meet in an obtuse angle to form an indentation. The second jaw has a sharply defined peak that meets the point of connection of the two sections when the jaws are closed. When a piece of sheet metal is introduced between the jaws and the handles are squeezed shut, the edge of the piece is displaced parallel to the rest of the piece.

BACKGROUND OF THE INVENTION 
When repairing a hole in a piece of sheet metal in an automobile body, the 
metal all along the periphery of the hole is "indented" inwardly, to form 
a short shelf all around the hole. A flat piece of metal is then attached 
to the shelf with blind, or "pop" rivets. The depressed section thus 
created is then filled in with putty to slightly above the level of the 
original surface, sanded smooth, and painted. 
It can readily be seen that the job of riveting the piece of metal to the 
shelf will be made easier if the shelf occupies a flat plane more or less 
parallel to the original surface. 
SUMMARY OF THE INVENTION 
This invention is directed towards a pair of pliers that will make it easy 
to form a shelf with the desired flatness. 
Essentially, this invention is a specialized pair of pliers designed for 
crimping metal. When this invention is used around the perimeter of a hole 
in a piece of sheet metal, it bends the edge of the metal into two 
sections: a downwardly and inwardly sloping section and a slightly longer 
shelf section, the latter being generally parallel to the original surface 
of the piece of sheet metal. 
To do this, the jaws of the pliers are not corrugated as jaws of 
conventional pliers are. Rather, one of the jaws is a sort of die, with a 
working surface that has two flat planes cut into it to form an 
indentation. The other jaw is a lever that forces the sheet metal to 
conform to the shape of the first jaw.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
A first jaw 10 and an elongated handle 20 are integrally molded together, 
as are second jaw 30 and elongated handle 40. The two members thus formed 
cross each other intermediate their ends and are pivotally secured 
together via rivet 50. Thus, squeezing the handles together squeezes the 
jaws together. 
The first jaw has an inner working surface composed of sections 60 and 70. 
Both surfaces are flat, and meet at an obtuse angle, with section 70 being 
shorter than and extending forwardly of section 60. An indentation is thus 
formed in the inner surface of jaw 10 which will serve as a die. 
Jaw 30 has a sharply defined peak 80 that, when the jaws are closed, 
touches the line that separates sections 60 and 70. It can be seen that 
when a piece of sheet metal 90 is inserted between the jaws and the jaws 
are squeezed together, the peak in jaw 30 forces the metal against the 
working surface of jaw 10, indenting the metal. Thus, in FIG. 3, the 
downwardly and inwardly sloping sections 100 were produced by section 70, 
and the flat shelf 110 was produced by section 60. It is to be noted that, 
as is shown in FIG. 1, the section 120 of metal that is indented is 
generally parallel to the section 130 of the piece of metal that never 
entered the pliers. This is made possible by the blunted forward tip 130 
of jaw 10, that allows the user to rock the invention in that direction 
which will allow the general parallelism between the indented sections of 
the metal and the original unbent sections to remain intact. 
As is conventional practice, a flat piece 140 of metal may be attached to 
the shelf by blind, or "pop" rivets 150. The resulting depressed area is 
filled with putty 160 and sanded down to the original level of the 
surface. The repaired area may thus be painted. 
Although the invention has been described with particular reference to the 
drawings, the protection sought is to be limited only by the terms of the 
claims which follow.
