UNITED STATES Patented May 19, 1903.



SPECIFICATION forming part of Letters Patent No. 728,471, datedMay 19, 1903.

Applaaion filed Juiylzl, 1902.

T0 all whom it may concern:

Beit known that I, JAN KULHNEK, residling at Prague, in the Empire-of Austria-Hungary, haveinvented certain new and useful Improvements in Semipermanent Portable Buildings, of which the following is a speciiication.

My invention relates to portable buildings, and has for its objectthe improved construction of such portable and semipermanent buildings, the main feature of which consists in the sides or walls or such parts thereof as are situated between another wall and a window or door, or between the foundation and the window, or between lche window or door and the ceiling, being formed of one single piece, by preference of artificial stone, having the door and window frames, as well as the lining of said frames, permanently attached in such manner that in jointing the different plates the door and window frames will also become jointed and ready for the hanging of the doors and windows.

Another novel feature is theim proved manner ot' connecting the different plates.

In the annexed drawings an improved building of this kind is shown, of which- Figure l is a perspective view with some of the plates raised away from each other to show the manner of their jointing. Fig. 2 shows, on a reduced scale, a horizontal section and the ground plan of a building of the most simple kind according to my invention. Fig.

3 is a partial section, enlarged, on line A B of Fig. 2. Figs. 4 and 5 are sections on lines C D and F G of Fig. l, showing themanner in which the corner-plates are jointed.

' In all figures similar letters of reference indicate corresponding parts.

For erecting a lbuilding' according to m invention a suitable foundation may be built in the ordinary manner, according to the desired ground-plan of the house. Upon this foundation are placed the side plates a a a, which have a thickness of from about four to twenty inches and are made of artificial stone of any known or suitable kind. In molding the plates which adjoin a door or window opening the adjoining part m of the door or window frame, together with its lining n, is placed into themold, so that frame and lining will appearV permanently and rigidly Serial No. 116 ,440. (No model.)

connected with the plate after the composition has set. I consider this mode ofattachment as the most advantageous; but the frames and linings may also be attached to the plates, after they have been cast, in any other suitable manner.

The plates a are connected by rabbet-j oints, the ledges b being less than half as thick as the plates, so that an opening p will remain between each pair of ledges, as shown in Figs. 3, 4, and 5. In the corners formed by the rabbetfledges b are placed rings c of eyebolts, which are by preference embedded into the plates, and the size of the rings about cor' responds to the cross-section of the openings 1o, formed by the rabbet-ledges. The plates are held together by iron rods q, which are pushed through the hollow space p and through the rings c of both plates. At their ends these rods q are provided with eyes,

through which a key g is driven to draw and V hold the plates tightly together. The openings p upon the outside of the building are closed up by cement, mortar, or in any other suitable manner. Rods q are drawn through the vertical joints of the plates, as well as through the horizontal ones.-

In buildings having a ground-licor only the ceiling also forms the roof; but where there is another story the ceiling of the one forms the door of the n'ex't story. The ceiling or roof is formed ofplates d, which are jointed similar to the plates a', and which may have a core of wire-netting, perforated sheet-iron, or of similar material for increasing their strength. The roof or ceiling plates d are attached to the walls by passing the vertical rods r of the latter through them. On top of the plates d countersunk washers are placed upon theends ofthe rods r, which latter are screw-threaded, so that the whole may be drawn and held together by means of nuts. The recesses in theplates ingwhich the washers and nuts are countersunk are then filled out with plaster, mortar, or such like. When the ceiling-plates d serve as licor-plates for another story, they may-be provided with a suitable covering on topsuch as, for instance, of xylolith or similar materiaLfIn all cases it is advisable to provide a suitable covering for the roof-plates d and to calk the joints of these, as well as IOO of the wall-plates, with moss, oakum, or such like or to east them out with asphalt.

Buildings constructed in this manner may at any time be taken apart, transported, and pnt up again Without loss of material. For this reason such buildings are particularly useful in eases Where temporary housing is to be provided fora large number of people.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In a portable building, the combination with two, adjacent Wallplates of artificial stone provided with rabbets in the adjoining edges with an opening between the ledges of said rabbets, ot' eyebolts embedded in said plates and having their rings in said opening in line with each other, a rod passed through said rings and having eyes at its ends, and keys driven in said eyes substantially as and for the purposes set forth.

2. A portable building comprising Wallplates of artificial stone having the adjacent parts of the window and door frames and their linings secured permanently to .said plates during the operation of molding the plates, substantially as and for the purpose set forth.

In testimony whereof I affix iny signature.
