ber | 1. At this rear portion of the vehicle the
duct 3| will communicate with the rear engine
space 30, and there may be arranged in any suit
able manner so as to guide cooling air to the en
gine 50. It will thus be seen that the various
hollow spaces 34, 35, and 3| will form a continuous
air conducting duct from the front of the vehicle
back tothe rear engine.
.
If it is desired to provide heated air to the
passenger compartment or to play upon the windshield to prevent the formation of frost or ice,
a similar duct 32 extending forwardly from the
rear of the vehicle may be provided. This duct
can be formed by the connection of the roof, roof
rails, and side walls similarly to the duct 3|. As
shown in Fig. 1 and the left hand portion of Fig. 2,
the duct 32 will connect with a duct V36 formed
utilized, if desired. Variations in the duct sys
tem are also apparent.
Accordingly, I do not intend that the scope
of this invention be limited to the exact features
shown and described, but only as may be required
by the claims which follow.
