PROCESS OF FORMING WALLS.

Specification of Letters Patent.

Patented Feb. 6, 19117.

Application filed June 21, 1915. Serial No. 35,195.

To all whom it may concern:

Be it known that we, EDWARD CONNELLEY and CHARLES C. CREW, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Processes of Forming Walls, of' which the following is a specification.

This invention relates to new and useful improvements in a process of forming walls,

or other. plastic material.

The object of the invention is to provide a process whereby a wall may be constructed from concrete or other similar material without the use of molds. As is well known concrete as now employedin the erection of buildings is applied in the formation of the structure only by the assistance of molds,

which must first be erected and the material in its plastic state then poured thereinand allowed to set or harden and the molds are then removed. .This process adds to the labor and expense of erecting the structure and it is the object of this invention to obvlate the necessity of using molds and to provide a process whereby the walls may be erected without employing molds.

With the above and other objects in View, the invention has particular relation to a novel process, which will be more specifically set forth in this specification, said process being also illustrated by means of the accompanylng drawings, wherein:

Figure 1, is a fragmentary side elevation of a wall.

Fig. 2,is a fragmentary transverse sectional view of a partially completed wall.

Figs. 3 and 4, show fragmentary transyerse sectional views of a wall, constructed in accordance with said process and,

Flgs. 5 and 6, show fragmentary transverse sectional views of modified forms of wall.

In carrying out the process herein described, reticulated partitions, as 1, 1, are placed in position and secured in fixed relat on to each other by means of any suitable kind of supporting spacers. In the drawings ordmary studding 2, is shown, to the opposite sides of which the reticulated walls, 1, 1, are secured and by means of which they The walls 1, 1, are formed of wire mesh or other similar open work and are secured against spreadmg between the studs 2, by means of suitable crossrods as a, and the space between them is then filled with gravel or some other suitable coarse aggregate. The spaces between the particles of the aggregate are then filled from either or both sides with mortar, grout or some other similar cementing material. This material is first reduced to a semi-liquid or fluid state and is forced through the reticulated walls and into the spaces between the particles of aggregate by hand, or a pneumatic jet, cement gun or any other suitable means. The process of applying the grout may be continued so as to form a plaster'or stucco finish for the wall of the desired thickness at a single operation for each face. Where a solid wall is undesirable but air spaces within the same are required, the penetration will not be allowed to reach the center, the same being regulated by the direction and force of the application or by increasing the thickness of the wall. In this manner air spaces may be left at the center of the wall to interrupt the conduction of heat and moisture. In case refrigerator or cold-storage walls or heat retainirig walls are desired a cork board or other non-conducting material of the required thickness may be introduced to form a core in the wall.

In case a very thick wall is required, it may be found desirable to secure to the frame work within the reticulated walls 1, 1, similar reticulated partitions 5, 5, which are spaced a short distance apart and arranged parallel with the walls, 1, 1. The spaces between the wall 1, and the corresponding partition 5, on each side are then filled with gravel and the fluid concrete composition, or grout, applied to each side of the wall, as hereinbefore explained and the space between the partitions, 5, 5, also filled with said composition. The composition will find its way through said walls, 1, 1, and partitions 5, 5, and will fill the spaces between the gravel in the manner hereinbefore explained, so that when the composition has hardened, a wall of solid concrete throughout will result. 1

It is obvious that in the construction of walls of unusual thickness, a number of spaces, such as is provided between the partitions 5, 5, may be arranged for, for the introduction of the cement composition to the interior portion of the wall.-

Another form of wall embodying the process herein set forth consists of a solid wall formed, for example of brick and a loo -- walls on each side of the structure so as to fill ,the spaces between the particles of aggregate only part of the way to the center of the structure and leave the center of the structure free from the plastic material to permit the air to circulate between the particles of the aggregate. I 2. The process of forming a structure consisting of securing wire mesh walls in spaced relation to each other, then filling the space between said walls with coarse aggregate, then forcing plastic material by means of a spraying device against the outer side of each of said walls and continuing said operation until said material-penetrates said wire mesh and fills the spaces between the particles of aggregate only part of the way to the center-of the structure on each side, leaving the center of the structure free from the plastic material to form an air space in the center of the structure.

In testimony whereof wehave signed our names to this specification in the presence of two subscribing witnesses.
