serting a tool between a ?ange such as 8 and its
parts thereof whenever desired, by merely- in

By punching the board or sheet l4 for reception
of the nail shanks, the nailing strips are forced
to ?t accurately and neatly along the marginal
edges of the board or sheet, this result being
impossible or at least uncertain in constructions
wherein the nail shanks form their own perfora

3. A vehicle door havinga frame including a
metallic ?ange at the inner side thereof, said
?ange having a supporting face and a back, and
of the board or sheet.
The modi?cation of Fig. 6 which is a View of
vthe’forward portion of the door shown’in Fig. 2,
‘shows how the slits I2 might be arranged in the
?anges 8, 9 and Hi to extend in a common direc
tion, so that a slight tolerance may be provided
in"'plac_ing the panel to insure a desired level of
its top .ed’ge'with respect to the sill of the window
aperturam" the upper portion of the door. This
modification suggests also the possibility of ex
tending the slits horizontally in all the inwardly
extended ?anges of the door to provide for lat
eral tolerance or clearance in adjusting the panel
‘toward ‘and from the uprights of the door prior
to driving the nailing strips into position. These

of parallel uninterrupted and continuous clamp

the inner faces [8 of the nailing strips, said heads
being made sufficiently thin that they may sink

back, said ‘supporting face having a series of elon
gated through slits punched therein from the
supporting face toward the back without removal
of metal,~ said slits thereby being bulged at the
back and dented along their length at the sup
having 3/1802, series of spaced elongated through
chisel cuts formed therein, each cut being con
stituted of not more than two opposed continuous
and "uninterrupted clamping edges both bulged
inwardly toward the back of the ?ange leaving an
elongated uninterrupted dent in the supporting 40
face co-extensive with the clamping edges, said
dent furnishing an extensive means of guiding
a nail to be driventhrough when poised substan
tially over the slit, the‘ continuity of the clamping
edges serving to provide substantially the same 45
resistance‘to deformation of the clamping edges
at ‘all points along their length when the nail is
driven through the slit from the dented side of the
?ange toward the bulged side thereof.
4. In combination, a panel including spaced
nails extending therefrom substantially at right
angles to the plane thereof, a support for the
‘panel comprising a sheet metal member having
modi?cations just mentioned are ordinarily not
a panel supporting face and a back, said member
needed when the part to be paneled is of stand
ard dimensions and undistorted. In other words,
the' arrangement shown in Figs. 1 and 2 will
having formed therein, at a spacing substantially
corresponding to the panel nail spacing, a series
automatically provide an accurate and workman

ordinary accuracy.
so as to bulge the sheet metal member at the back
and to dent it for providing a nail guide in the 60
supporting face, both the bulge and the dent
‘ Although the invention has beenexplained and
‘illustrated as applied to a door of a vehicle, it
is to jbejunderstood that other parts of a metal
lic vehicle body may be paneled or ?nished in
‘the same manner. The method and means here
in disclosed for the application of trim or panel
ing‘have been found effective for reducing the
> cost of both material and labor, with a substan
tial [saving of time, the job being completed with
the same degree of neatness and accuracy, as
"was possible in the use of structures heretofore
’ What is claimed is:
_1.,I‘n a self-locating panel structure, the com
bination of a support to be paneled and com
of elongated through chisel cuts each punched
being elongated and substantially co-extensive in
length with the length of the elongated chisel
cut, and each chisel out being constituted of no
more than'one pair of opposed continuous and 65
uninterrupted parallel clamping edges of sub
stantially the length of the chisel cut, the con
tinuity of said clamping edges serving to furnish
approximately the same degree of resistance, at
all points along the length thereof, to deforma
tion of the clamping edges when the nails of the
panel arepoised substantially over the elongated
dents and driven through the chisel cuts from
‘the supportingv face of the sheet metal member
toward the back thereof.
5. In a panel mounting structure, a sheet
metal support having a panel supporting face
7 and a back, and a series of spaced elongated
through chisel cuts formed therein, each out be
Cl ing constituted of not more than two opposed
continuous and uninterrupted clamping edges
both bulged rearwardly toward the back of the
sheet metal support leaving an elongated un
interrupted dent in the supporting face co-ex
10 tensive with the clamping edges, said dent
furnishing an extensive means of guiding a nail
to be driven through when poised substantially
over the slit, the continuity of the clamping edges
serving to provide substantially ‘the same resist
ance to deformation of the clamping'edges at all
points along their length when the nail is driven?
through the slit from the dentedgside of the sup-
port toward the bulged side thereof.
