METHOD OF ERECTING WALLS.

SPECIFICATION forming part of Letters Patent No. 792,451, dated June 13, 1905.

Application filed August 2'7, 1903. Serial No. 170,911.

To (1.7] 1/r7m7n/ it 721111.511 (1071103771,:

Be it known that I, EMIL PRUss, architect, a subject of the German Emperor, residing at Schonehergerstrasse 18, Berlin, S. WV, Germany, have invented certain new and useful Improvements in Procedure of Erecting falls with Metal Reinforcing-Strips, of which the following is a specification.

My invention relates to a procedure of erecting walls with metal reinforcing-strips; and it consists in the novel steps hereinafter described, and pointed out in the claims, securing and facilitating the insertion of the plates or tiles forming the wall between the metal strips and the formation of spaces between said plates subsequently to be filled with mortar.

Reference is to be had to the accompanying drawings, forming part of this specification, in which like characters indicate like parts wherever they occur.

Figure I is a front elevation of a framework of metal reinforcing-strips, partly showing plates inserted into the meshes of the framework, the strips being held in position by cramps or pegs provided with slots for engaging the metal strips forming the framework. Fig. 2 is a cross-section on the line Fig. 3 is a perspective view of a cramp or peg with the slots crossing each other, one of which engages the horizontal and the other the vertical strip of the metal framework. Fig. 4 is a front elevation of a modilication of the wall illustrated in Figs. 1 and 2, having only one set of reinforcing metal strips running in horizontal direction. I

The wall to be erected in accordance with my invention comprises a reinforcing metal framework and plates inserted between the metal strips of said framework and fastened by mortar applied between the several plates. The plates are formed in any suitable mannera. r composed of bricks-and of such size that they fill the distance between two horizontal strips of the framework, leaving only a small space to be filled with mortar. The wall itself is essentially known and needs no detailed description, my presentinvention consisting only in the special procedure to erect walls of the general form of construction outlined above.

When erecting a wall with framework of horizontal and vertical strips positioned in different planes, as indicated in Figs. 1 and 2 of the drawings, I arrange the horizontal strips a and the vertical strips 6 in any suitable manner between carrying structures, as is well known to those persons skilled in the art. This being done for awhole wall or for part of same, I fix the points of intersection of the two'sets of metal strips by applying cramps or pegs 0, preferably made of wood and having slots cl a crossing each other for engaging the intersecting parts of the strips (0 b, as is clearly illustrated in Fig. 3 of the drawings. Now the plates or tiles f are inserted into the meshes of the framework so as to be held in position by the said cramps or pegs 0. In a preferred form of procedure I put on one side of the wall a ladder adjustable in height in such a manner that the edges of the beams or bars 9 on the side contacting the wall are coincidentwith the desired plane of the wall, thus securing an easy control of the correct plane of the wall when inserting the plates f. This ladder, however, or its equivalent may be dispensed with. A number of plates f being inserted into the meshes of the framework, which may be varied at will, the spaces between the several plates are filled with mortar. This can be easily done by throwing the mortar into the spaces from one side of the wall. In order to avoid that the mortar passes through the mortar-spaces and falls down on the other side of the wall, the spaces may be closed on that side of the wall opposite to the side from Which the mortar is thrown into the spaces. When the mortar has sufficiently set, the cramps or pegs 0 are thrown from between the plates or tiles f, and the spaces thus left free are likewise filled with mortar.

In Fig. 4: I have shown a modified form of the wall to be erected in accordance with my present invention. This form of the Wall has only one set of reinforcing-strips-namely, the horizontal one (0. Consequently the cramps or pegs 0' need only one slot correspending to the one set of strips. The manner of proceeding for this form of wall is essentially the same as formerly described.

My new procedure results in considerable advantages over the known method of erecting walls of the said kind. The work of filling the meshes of the framework is facilitated and advanced, especially in rainy weather, by preventing the load of the plates from pressing the mortar out of the separating-spaces, and a mortar poorer in lime or cement may be employed to fill the spaces.

Having now explained the nature of my invention and in what manner the same may be performed, what I claim, and desire to secure by Letters Patent, is

1. A method of erecting walls which comprises the following steps: securing in position a plurality of approximately horizontal and parallel metal strips; engaging on said strips cramps or pegs of a thickness greater than that of said strips and spaced apart from each other; placing between said cramps ver tically disposed tiles or plates; filling the spaces between said tiles and said strips with mortar or cement; removing said cramps after the settingof such mortar; and filling the voids made by the removal of the cramps with mortar or cement.

2. A method of erecting walls which comprises the tollowing steps: securing in position a plurality of approximately horizontal and parallel metal strips and a plurality of metal strips adjacent and crossing said horizontal strips; engaging on said strips at their points of intersection cramps or pegs of a thickness greater than said strips and spaced apart from each other; placing between said cramps vertically-disposed tiles or plates; filling the spaces between said tiles and said strips with mortar or cement; removing said cramps after the setting of such mortar; and filling the voids made by the removal of the cramps with mortar or cement.

3. A method of erecting walls which comprises the following steps: securing in position a plurality of approximately horizontal and parallel metal strips and a plurality of metal strips adjacent and crossing said horizontal strips; engaging on said strips at their points of intersection cramps or pegs ot' a thickness greater than said strips and spaced apart from each other, said cramps or pegs having slots in which said strips engage; placing between said cramps vertically-disposed tiles or plates; filling the spaces between said tiles and said. strips with mortar or cement; removing said cramps after the setting of such mortar; and filling the voids made by the removal of the cramps with mortar or cement.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

EMIL. PRUSS.
