Describing in illustration but not in limitation and referring to the drawings:

There is considerable need for a housing which can United States Patent O 3,257,932 Patented June 28, 1966 rice be shipped in folded or knocked down condition to any part of the world, including the Arctic, or Antarctic and also including remote and inaccessible locations, for covering and protecting machinery and equipment such as turbines, engines, generators, radar equipment, scientific measuring equipment and the like. The housing lends itself to such service, both in cases of military installations; also for scientific expeditions, and in some cases for normal civilian uses. This invention relates to a ventilator construction for such housings.

One of the great advantages of the ventilator of the invention is that the elements of the ventilator `are themselves relatively light, and also are not bulky. They can be shipped or transferred or hand carried to the site and installed readily with a minimum of tools.

,The structure is primarily of aluminum alloy, and is designed to resist the elements and has very high resistance to corrosion in various environments. The structure also is designed to withstand adverse conditions, which -may be encountered, for example, in the Arctic and Antarctic, such as windsof 135 miles per hour, and various atmospheric conditions, such as snow, sleet, ice and hail. Provision has been made for excellent ventilation, to carry olf any gases generated by the machinery `or equipment, and to provide comfortable working conditions for personnel.

The ventilator housing is essentially constructed out of a plurality of snap-in metallic extrusions with appropriate supporting means. For further discussion on the construction of these metallic extrusions, reference is made to our above-identified copending application for Housing.

Referring now to the drawings in detail, the housing consists of footings 40 on which are supported side walls 41, end walls 42, a roof 43, and Ventilating assemblies 44, which are described more in detail later.

As best seenin FIGURE 1,each end of the housing has an access opening 94, which may be closed by a suitable door if desired.

At intervals suitably on either side of the end walls 42, there are provided doors 103 and at suitable places in the side walls there are provided doors 104.

At a central point in each of the oppositely sloping roof panels of a' pair, it is desirable to locate a ventilator. Openings 146 are suitably punched in Vthe webs of lthe extrusions 57 forming the roof beneath the ventilator as best seen in FIGURE 2. Centrally located at each ventilator is placed a suitable rectangular collar 147 which consists of a web 148 desirably thickened toward the bottom, a transverse bottom flange 150 and an outwardly aring top flange 151. There is an inwardly extending intermediate rib 152 from the web. The sections of the extrusion 147 are mitered at the corners and the rib 152 A is cut away at 153 near the corners to receive an upwardly extending angle 154 best Seen in FIGURES 2 and 6 which is secured to the collar 147 as by rivets 155. 'I'he collar 147 is fastened to the roof panel by bolts 156 with caulking if desired.

The collar 147 is desirably braced by cross braces 157 secured to theribs 152 as by rivets 158, best been in FIG- `URE 16. The angle uprights 154 extend considerably above the top of the collar and at the top there are suitably mounted, as by welding, nuts best seen in FIG- URES 2 and 3. The cap or cover for the ventilator 44 consists of supporting angles 161 extending .transverse to` the ridge of the roof, resting on the nuts 160, and secured at the ends as by welding to brackets 162. The top and the two sides of the cover consist of suitable aluminum snap-in extrusions 163 best seen in FIGURES 2 and 4 and consisting of webs 164 which have at one edge female socket sections including flanges 165, 166 and 167, which 3 are generally in the shape of an inverted trapezium. Near the edge toward the web 164 there is a projection 168 which ts into an interlock recess 170 at the opposite end of the web 164. Adjoining the interlock recess 170 on the end of the web is a projection 171 following the inside of the trapezium shape of the flange 165 and having an angularly bent rib 172 at the end which interlocks within a rib 173 on the trapezium flange 165.

A rib 174 from the web fits immediately inside the trapezium ilange 167 of the next extrusion, so that by deecting the extrusions they can be snapped together as shown in FIGURE 2.

At front and back corners an extrusion is provided which resembles the others but has a curved web 164 as best seen in FIGURE 2.

The corresponding extrusions 163 and the angles 151 are bolted to the nuts 160 at the uprights 154 by bolts 175 extending through the extrusions and through spacers 176 and then through the angle 161 and into nut 160.

At the ends of the extrusions 153 brackets 177 are secured to the extrusions as by rivets 178, and the brackets support extrusions on the sides of the cover which are connected to the brackets by rivets 180. At the top of the sides the webs are suitably cut olf at 181 and at the bottom special cooperating snap-in extrusions 182 are suitably used having ribs 183 at the extreme bottom edges. The

same is true of the `bottoms of the front and back portions as shown in FIGURE 2.

At the center of the roof panel, as best shown in FIG- URE 4, there is a metallic extrusion having female socket sections at both ends. This permits reversal of the order of the extrusions so that the special bottom snap-in extrusion 182 can be secured to both ends of the side panels.

As best seen in the FIGURE 2, the bottom of the cover terminates just below the outer flaring portion 151 of the collar but at a considerable distance outwardly thereof so that gas flowing upwardly as shown by the arrows 184 will pass through the openings 146 .and through the space within the collar 147 and then will pass downwardly in the space between the bottom edge of the cover and the roof as suggested by arrows 185 and 186.

The ends of the extrusions forming the top of the cover are suitably connected to the extrusions at the sides by an extrusion 187 which has a web 188 running along the ends of the extrusions at the top and a ange 190 joined to the extrusions at the top by rivets 191, and a ange 192 extending under the extrusions 163 and then an angle ange 193 joined to the top-most side extrusion by rivets 194.

In some cases it is not suflcient to rely on natural ventilation and in FIGURES to 12 we illustrate a modied Ventilating assembly.

In this case an opening 195 suitably of circular form is cut in the cover extrusions 57, and a rim 196 is secured by rivets 197 to `tinish the inner edge of the opening. The collar 147 is constructed as before and provides the uprights 154 at the corners which are to connect to the cover.

Secured to the `roof extrusions for bracing purposes on the sides are angles 198 anchored by rivets ,200 to brackets 201 secured by rivets 202 to the extrusions 163.

On top of the roof but under the cover is provided a frame -203 which is secured to the roof extrusions 57 at 204 and which has mounted thereon an electric motor 20S provided with a shaft 206 and pulley 207 which connects by a belt 208 with a pulley 210 on shaft 211 joumalled on bearings 212 in the frame carrying an exhaust fan impeller 213.

It will be evident that the fan will draw air through the opening in the roof and discharge it in the space between the ventilator cover and the roof.

In view of our invention and disclosure variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of our invention without copying the structure shown, and we, therefore, claim all such insofar as they fall within the reasonable spirit and scope of our claims.
