SPECIFICATION forming part of Letters .Patent No. 718,429, dated January 13, 1903.

To all whom, it may concern:

Be it known that l, HENRY D. CONWAY, a citizen of the United States, residing at .I ackson, in the county of Jackson. and State of Michigan, haveinvented certain new and useful Improvements in Construction of Buildings and I do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable Others skilled in the art to which it'appertains to make and use the same.

tures of the invention.

This invention has relation chiefly to lireproof structures-such as dwellings, officebuildings, assembly-halls, and the like-and aims to simplify and cheapenV the construction of buildings of the character aforesaid, as well as to increase their strength and durability. Y

Aln accordance with this invention a form is set up and the space between the sides is filled with cement, which when set and hard is self-supporting and constitutes the walls ofv the structure. The form contemplates molds for exterior and interior decoration and finish, such as the cornice, panels,'moldings and trimmings around Window, door, and like openings.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modiiication,still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure l is a vertical section of the front portion of a building constructed in accordance with and embodying the essential fea- Fig. 2 is a View similar to Fig. l of a modification. Fig. 3 is a front view. Fig. 4 is an enlarged section. Fig. 5 is a perspective view of a modified form of mold for cornice or like finish. Fig. 6 is a section of the parts shown in Fig. 5, the dotted lines showing the upper part of the mold thrown upward to admit of the lower portion being readilydrawn down away from the cornice or like part.

Corresponding and like parts are referred `Application led April l0, 1902. Serial No. 102,273.` (No model.)

to in the following descriptionr and indicated in all the views of the drawings by the same reference characters.

The form comprises inclosing sides, the space being adapted to be filled by concrete or like material employed in the formation of artificial stone. The front side l and the inner side 2 are spaced apart a distance corresponding to the thickness of wall desired and each is strengthened and st'iened by Yposts 3 and 4, which are braced in any substantial manner and tied by bolts 5 or like securing means. Planks or boards 6 are secured to the posts 3,and corresponding planks or boards 7 are attached to the posts 4. These boards are jointed at their meeting edges by matching tongue and groove of `any form which will retain the boards in alinement and prevent escape of moisture. The inner faces of the boards are covered by sheet metal, as shown at 8, to prevent absorption of moisture by the boards and a too-rapid drying out of the concrete when setting. When the front of the building is to be laid o in blocks to represent stonework or other inish,ribs 9 project inward from the front side l of the form, and these ribs 9 may be of any shape, according to the required form of joint Or groove to be impressed into the front of the building. The ribs 9 may be an integral part of the board 6 or may be strips attached thereto, and the faces designed to come in contact with the concrete are protected by sheet metal,as indicated most clearly in Fig. 4.

The form is provided with openings correspondingto the window, door, and other openings of the building and is of such construction as to admit of its ready adaptation to the character of structure to be erected. Molds 10 and ll surround the openings in order to give a linish both to the exterior and to the interior of the building, should the same be desired. Obviously one or both of the molds 10 and 11 may be dispensed with.

These molds l0 and 1l are preferably of sheet IOO struction and reducing the amount of combustible material generally entering into the construction of a building. Molds 12 and 13 are included in the front 1 of the form when it is required to embellish the front of the building at any required point or points, and these molds are preferably constructed of sheet metal and are attached to the posts 3, bracing-pieces being interposed between said posts and the molds to stii'fen the latter and preserve their shape. In case it be desired to decorate the lower portion of the wall of a room an inner mold, as 14, is provided, and where a molding and cornice is desired at the ceiling a mold 15 is provided.

To give the accustomed cornice-finish to the top of the wall, a mold 16 is provided and is braced by stays 17 and 18, projected outward from the sides 1 and 2. Angle-irons 19 connect the inner ends of the stays 17 and 1S with the boards 6 adjacent to the mold 16. In the event of the mold having an undercut portion or cove, as shown in Figs. and 6, the stays 17 and 18 are pivotally connected, as shown at 20, and upper and lower parts of the mold 16 are separable to admit of the upper portion being thrown u pward,as indicated by the dotted lines in Fig. 6, whereby the lower portion may be drawn from the cornice or work by a downward movement, thereby admitting of freeing the cove or undercut portion of the mold.

In buildings having the floors constructed of concrete, as shown most clearly in Fig. 1, the inner side 2 of the form is left open to admit of the concrete forming the wall and the floor uniting and forming one homogeneous mass. The cornice in the angle between the ioor and wall also constitutes a bracket to support the door and brace the juncture of said iioor with the wall, as will be readily comprehended. The concrete iioor is indicated at 21 in Fig. 1, and in practice is strengthened by wire-cloth, metal lathing, or iron rods 22, which likewise extend into the space formed between the sides 1 and 2, so as to be ernbedded in the wall of the structure, thereby forming a firm bond and tie. The wall of the structure is likewise stiffened and braced by rods 23, beams or bars 24 being provided at dierent point in the height of the wall to receive the ends of the rods 23, which are connected thereto in any substantial way so as to form a stable structure. The bars or beams 24 extend lengthwise of the building and are preferably located at the floor-lines, and the outer ends of the rods 22 are connected thereto. These parts or beams 24 may be of any shape such as commonly employed in the construction of buildings.

In the class of buildings not required tol have iireproof or concrete floors the joists 25 have their beveled ends extended into the form, so as to become embedded in the concrete during the formation of the walls. This is indicated most clearlyv in Fig. 2. When the floors are constructed of concrete, the ceilings may be suitably ornamented by providing plates having the design impressed therein, said plates being braced from below bya suitable framework, such as commonly elnployed in the construction of concrete iioors. In order that the molds and Various ornamentations may present a smooth and sharp finish, it is necessary to plaster the same in the wellknown manner, the body of the wall or iioor being filled in with ordinary concrete or like composition consisting,essentially,of cement, sand, stone, gravel, and the like.

j Having thus described the invention, what is claimed as new is- 1. A form for the construction of buildings of cement and like material, the same having openings in its inner side corresponding to the Hoor-lines of the building to admit of the fioors and walls merging or becoming united, substantially as described.

2. A form for the construction of buildings of concrete and like material, the same having openings corresponding to the window, door and like openings of the building, and a mold forming a side of the form and arranged adjacent to an opening thereof to provide a iinish to the corresponding opening of the structure when completed, substantially as set forth.

3. A form for the construction of buildings of cement and like material, the same having openings corresponding to the openings of the building, and a mold surrounding an opening at each side to provide a finish to the opening in the wall at both sides, substantially as set forth.

4. A form for the construction of buildings of cement and like material, and a mold extended from the inner side of the form adjacent to the floor-line to provide a molding or cornice at the angle between the floor and wall, substantially as set forth.

5. A form for the construction of buildings of cement and like material, comprising a mold projected from the outer side near the upper end to provide a cornice, said mold comprising upper and lower movable parts to admit of drawing the mold from the work after the latter has set, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
