PORTABLE BUILDING boNsTRUcTIoN Filed May 7, 1952 2 Sheets-Sheet '2 ATTORN EYs Patented Aug. 28, 1934 ram orries The improvements coveredby this invention are applicable to small ,outhouses andsmall storagehouses, such as privies, tool houses, and the like. The object of the inventionis to'pro- E vide an all steel fire proof sanitary building that is of simple design, comparatively cheap in first cost, built of enduring materials, andthat is so light in weight that it can be easily moved from one location to another as may be desired.

In order to illustrate a practical application of the invention, I have shown, on the accompanying drawings, an earth pit privy which is in part comprised of an all steel sanitary building that embodies the improvements of this invention.

Fig. 1 is an elevation of a complete earth pit privy.

Fig. 5 is a horizontal section on the line 5-5, Fig. 1.

Fig. 6 is an enlarged horizontal section through the door.

Fig. '7 is a detail of a door hinge. The sanitary building is shown fastened by means of anchor bolts 11 (Fig. 3) to a suitable reinforced concrete slab 12 which rests on a concrete curb 13 that surrounds an earth pit with a Wooden lining 14. The pit is shown of square section in Fig. 2 which is a preferred section, but the section of the pit itself is immaterial and may be round or other shape. A paper joint 15 is made between the slab 12 and curb 13 so that the slab can be easily removed to a new location when it is desired to do so.

A bottom ring 16 is fastened down-onto the '40 concrete slab 12 by the bolts 11, this ring being an angle in cross section and having its upright portion bolted or riveted to a vertical corrugated metal sheet 1'7'which constitutes the circular wall of the building and is bolted at the top '45 to the vertical leg of an angle shaped ring 18.

The corrugated sheet 17 is in a number of vertical sections jointed to each other as on Fig. 5. Certain of these sections, 17a shown at the two opposite sides of Fig. 1, have ventilating openings section on the line 2 --2,

" at their lower ends (Fig. 4) which are overlapped on the inside by' corrugated sheets 19. The corrugations of the two sheets 1'7 and 19 are in opposite directions at registering points so as to leave a number of passages for the admission of air as shown by arrows on Fig. 4. The door opening is shown at the front of Fig. 1. The sheets 17 adjoining this opening have vertical reinforcing angles 20boltedthereto to form door jambs. The door comprises corrugated plates 21 similar to those constituting the wall. Its curved shape in horizontal section is maintained by stiffening angular braces 22. V

This shape makes it fit neatly against the bottom and top rings 16 and 18 of the wall. It is stiffened along its vertical edges by angles 23-65 and fastened by means of hinges 24; which overlap the or brace 26 at that side of the door.

The plates and braces of the door and the hinge leaves that are fastened thereto are preferably welded. or riveted together to form a unit of substantial strength andustifiness. The hinges are preferably inline wih horizontal braces as indicated on 1. In the transverse section the door comprises the intermediate plate 21 and side plates 25 which overlap the door jambs and make a complete closure.

The roof 2G is of conical shape made in several sections of sheet metal, corrugated or'not as preferred, and preferably beaded at the outer edge, as at 27, for stiliness.

The roof overlaps horizontally to a considerable width of cave beyond the side wall, and is held above the latter by z-bars 28 having a lower flange fastened to the horizontal portion of the top ring 18 and an upper flange extending outward beyond the side wall and fastened to the roof plates. This provides an open air space at the top of the building for ventilation.

A toilet seat 29 is shown in Fig. 2, elevated of course above the floor. In Fig. 2 there is shown an upright pin 30 projecting from the corner of the slab 12 so as to serve as a stop for the door 21 in the open position of the latter.

The material of the building is preferably galvanized steel and the shape circular. This shape offers improved sanitation due to the elimination of corners. It also provides a greater stiffness and, fora given size, offers less wind resistance than other shapes. The circular shape and the corrugated sheets make it possible to secure the necessary strength without any framing or bracing other than the top and bottom angles.

The method of ventilation is especially efiective. There is a continuous circulation of air entering near the bottom of the building and passing 5 out at the top; The inside cover plate 19 may be spot welded at 31 Fig. 5 to the upper plate 17a, or may be otherwise fastened thereto beforehand and the two parts handled as a single plate in erecting the building. This type of ventilator 131"0 prevents access to the floor of the building by rats and other animals and insects while allowing a continuous current of air to enter near the bottom.

The bottom angle or sill will have its ends welded or riveted together. It serves as a form for pouring the finished floor 32 (Fig. 3) forming a slight elevation of the slab 12 within the building wall.

The roof supports are advantageous in that the top arms 33 and the bolts which fasten the roof to them are outside of the vertical lines of the side wall. Thus, any leakage through the bolt holes will not permit the entrance of water within the building. The conical shape of the roof brings the eaves of it down to the desired level in a simple continuous extension of the roof plates Without the necessity of special plates or the like for this purpose. 7

Being of steel, the building is fire proof and has weather-resisting qualities giving it longer life than the frame buildings usually employed and also reducing cost of maintenance. Steel also has an advantage in that it is not so apt to be taken away by unauthorized persons, as is the casewith wooden buildings which are destroyed for fire wood. It is comparatively cheap even though it is made of steel, because of the avoidance of bracing or stiffening members. The design permits fabrication and preparation very largely in the shop. It requires very little labor in field work or erection. It is designed particularly for car load shipments, the sections being capable of nesting in comparatively small spaces.

What I claim is:

1. A steel building of the character described, with a side wall made of a plurality of vertically disposed corrugated metal sheets fastened at their vertical sides to each other, a sill to which said sheets are fastened at their lower edge and a top ring to which they are fastened at their upper edge, a roof supported from said top ring, and spaced above the upper edge of the side wall, ventilator openings being provided near the bottom of the wall cooperating with the openings at the top to cause upward air currents through the building.

2. A steel building of the character described, having a side wall comprising an upper part overlapping the upper part and with the ridges of the vertical disposed corrugations and a lower part with vertical corrugations in the opposite direction at registering points so as to leave openings for admission of air.

3. A steel building of the character described, having a corrugated side wall with the corrugations disposed vertically and having door jambs made of comparatively narrow strips of sheet metal with corrugations engaging the corrugations at the corresponding edges of the side wall, said strips having their free edges bent at substantially a right angle so as to stiffen them.

4. The steel building of claim 1, being of substantially cylindrical shape and being self-supporting between the top and bottom of the side wall because of the resistance to buckling offered by the corrugated sheets,

5. The steel building of claim 1, in combination with a concrete slab floor on which the sill is mounted.

6. The steel building of claim 1, in combination with a concrete slab floor on which the sill is mounted, with the concrete on the inside elevated above the bottom of the sill.

'7. The steel building of claim 1 including a concrete slab floor on which the sill is mounted and a concrete curb on which said concrete slab fioor is supported detachably and a thin parting strip between said slab and curb.

8. A steel building of the character described ASBURY CLINTON DECKER.
