Referring more particularly to the drawing, I0

has been previously explained, are employed for
drawing the adjacent side bars up right against
each other.
The front end of the shelter has a pair of
vertical end frames 28 and 28a. The outer side
bars of these two frames, as has been previously
explained, are rectangular in cross section. The
door frame 45 is hingedly connected at 46 to the
inner side bar 41 of the front frame 28“. This 5
door is grooved along its free edge as shown at
48 to receive a complementarily formed grooved
portion on the inner bar 49 of the front frame 28.
The lower bars 50 of the front frames are
bolted to the bar |2 of the base frame It].
A pair of top frames, generally designated by
the numerals 5| and 52, have their end bars 53
bolted as shown at 54 to the top bars of the
side frames 20.
The outer side bar 56 of the rear top frame
52 is bolted, as shown at 51, to the top bars of the
end frames 31, 38, and 39. A front top frame 5|
has its outer side bar 60 secured to the top bars
of the front frames 28 and 28a.
The intermediate top frames, generally desig
nated by the numerals 6| and 62 have their side
bars 63 either bowed or these side bars are formed
of a wider strip of wood and sheared off from the
central point towards the ends thereof. It will
be noted that all of the frames are provided with
screen wire'and the frames have countersunk por
.tions along their inner edges to receive the screen
wire or the screen wire may be tacked upon the
outer surface and the securing means for the
screen wire covered by heading as indicated at
65. In view of the particular construction of the
intermediate top frames 6| and 62, the screen
wire is tacked upon the outer surfaces of the
bars 63 so that the screen wire will be inclined
at an angle towards the side walls of the shelter
and form an intermediate portion of'the top
frames 6| and 62. The particular construction
of these frames provides for reinforcement of
the top.
‘ The frames 5|, 52, Gland 62 are all removably
connected together by bolts and the intermediate
frames GI and 62 have their end bars bolted to
the top bars of the side frame 2|, as shown at 69.
A ridge pole 10 is raised above the top of the
shelter by means of standards 1| which are bolted, 5
as shown at 12, to the outer side bars of the top‘
frames 5| and 52. These bolts at the rear of thei
shelter also pass through the top bars of the
intermediate frame 38.
An intermediate standard 15 is mounted upon 10
the two adjacently. connected bars 63 of the inter
mediate top frames 6| and 62 and the top of this
standard is cut so that it will be neatly received
by the angular portion of these frames.
A pin 16 is carried either by the ridge pole 10 15
or the standards ‘H and 15 for aiding in retaining
the ridge pole on the standards.
A-canvas top covering 80 is stretched over the
ridge pole and has its free ends 8| overhanging
the side walls of the shelter.
If desired a canvas covering may be supported
upon the side and front walls of the shelter and
provision may be made for rolling the canvas
to an inoperative position near the upper ends
of the walls when the canvas covering is not de- 25
sired or required.
I claim:
In a screened shelter, an assemblage of upright
screen frames, and a roof for said assemblage
comprising top screen frames, at least one of the 30
centrally located top frames being bowed up
wardly to act as a truss and prevent the top
frames from sagging downward.
