body is immaterial as it may be an ordinary

These cables as well as the cables
forming the guides 52 may be three-sixteenth

One end of each cable
is extended around a vertically journaled guide
pulley ‘ll in the rear of each winch and then
horizontal outwardly under a horizontally jour
naled guide pulley l2 suitably supported by the
body or frame substantially beneath the hollow
sides i3 and then upwardly through the latter
between the inner and outer walls thereof, through
suitable holes 'i3 provided in the side frames lil.
These cables are then extended horizontally over
guide pulleys lfîl and then horizontal rearwardly
to the rear corner posts or other suitable vertical
frame members, where they are extended around
guide pulleys ‘l5 and then upwardly near the rear
end of the body over guide pulleys ‘le supported
beneath the roof 24 constituting the solid or per
manent portion of the roof of the vehicle body.
During this movement, the cables will freely slide
through the bows and this will also be the case
i when the top is closed or extended rearwardly to
cover the open top of the body. To do this, it is
simply necessary to turn the crank and shaft to
the right or in the opposite direction to oppositely
wind and unwind cables so as to pullrearwardly
on the rear cross bow which will successively
space the cross bows and extend the cover to the
rear of the body in the reverse order from that
in which said parts move when the top is opened
as heretofore explained. When so extended, the
tarpaulin may be tieddown by drawing the llaps
33 and 3e together and tightly over the top of

the other portions leading over the guide pulleys

forwardly thereof and then the next cross bow
and so on until all of the cross bows have been
moved forwardly to the rear cross bow or trans

thus opened and will result in the tarpaulin being

Of course, since the doors 20 do not extend as

the doors may be opened at any time by unbolt
