INSTALLATION OF WINDOWS IN PANaiS OF A SEDAN DELIVERY TRUCK
By 0. B. Berndt
Division of Cereal and Forage Insect Investigations
Sedan delivery trucks, which are used to a considerable extent by
Federal workers, are delivered with metal panels on the sides of the
truck bodies. For many types of work, particularly in congested areas,
observation to the side and rear is'essential, and the opaque panel
construction limits such visibility. To remedy this defect, a method
of installing windows in the sides of sedan delivery truck bodies has
been used in Bureau shops at Moorestown, N. J.. Toledo, Ohio, and
elsewhere. Since a number of inquiries relative to such window
installations have been directed to the Toledo office, it is thought
that a description of this method would be generally useful.
The inside fiberboard wall covering the framework of the car is
first removed to expose the bracing members as installed at the
factory. The two struts A and B in figure 1, lateral of the center
strut, are then removed.
A paper template is made and pasted on the outside surface of the
panel in the position in which the windows are to be cut. The template
follows as nearly as practical the contours of the panel. A 1-inch
margin was left between the edge of the template and the edge of the
panel in the truck illustrated. 'If the panels are larger, a wider
margin is allowed in the interest of proper proportioning, appearance
and strength. Vith the template in place, a scriber is used to mark
the line of the cut on the metal surface (fig. 2).
A i-inoh hole is drilled within the surface covered by the pattern,
at a point near the line where the cut is to be made, and the panel is
cut along the scribed line with off-set tinner's snips. A file is used
to remove rough spots and to round corners.
A strip of channel rubber similar to that commonly used in install-
ing automobile windows is worked over the cut edge of the metal with a
screw driver or a similar tool, so that the narrow groove in the rubber
fits over the metal edge (fig. 3-A). The rubber strip is cut so that
a tight butt joint is made at the top of the window. This Joint is
later sealed with liquid rubber and sanded until it is practically

The rubber is then removed and fitted over a glass pane cut to a
size inch larger all around than the opening into which it is to be
fitted. The pane with its periphery imbedded in the wide groove
(fig. 3-3) of the channel rubber is then inserted in the opening with
the overlap of the pane on the inside of the panel.
When the pane is in place, the framework of the window in formed
with wood pieces fashioned to conform to the contours of the window,
and attached solidly with nails and screws to the remaining original
supporting framework (fig. 4). The curved corners can be installed
most easily by use of short metal strips. A strip of a neutral shade
of standard-gage linoleum ia fastened to the new framework with small
box nails and cut to a width equal to the thickness of the frame
(fig. 5). The inside fiberboard wall is then attached in its original
position,and the window openings are cut to correspond exactly with
the edges of the linoleum strip on the window framework.
An interior view of the finished Job is shown in figure 6, and
the exterior appearance of the car with the windows installed is
shown in figure 7.
