MOLD FOR CONCRETE WALLS.

Specification of Letters Patent.

Patented Aug. *7, 1906.

Application filed March 29, 1906. Serial No. 308,632.

To all whom it may concern.-

Be it known that I, J OHN J. DANIEL, a citizen of the United States, and a resident of Cambria, in the county of Columbia and State of IVisconsin, have invented certain new and useful Improvements 1n Molds for Concrete Walls; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in certain peculiarities of construction and combination of parts, as hereinafter fully set forth with reference to the accompanying drawings and subsequently claimed, its object being to provide a simple portable molding apparatus for forming cement facings for walls, the apparatus being so constructed as to be readily assembled, thereby making it possible for those unskilled in the art to construct cement facings for walls at a small cost.

In the drawings, Figure 1 represents a perspective view of a molding apparatus made in accordance with my invention, said apparatus being shown adjusted to the side of a building to which a cement facing is being applied; and Fig. 2 is a face view of one of the mold-boards, showing the arrangement of print-strips.

Referring by letter to the drawings, A indicates mold-boards, which, together with their integral parts, constitute sectional in olding-frames of a series that in practice are adjusted one upon the other as the height of the wall-facing progresses, the length and width of the mold-board being immaterial. Each mold-board is provided with eye-plates B, countersunk into the upper edge thereof, into which are fitted shanks C of thrust-bars D, which bars at their rear ends are secured to a backing-timber E, that is parallel with the mold-board. The lower edge of the moldboard is beveled rearward of its face and also has secured thereto eye-plates F, which receive brace-rods G, the opposite ends of said rods being fitted in eyes of the thrust-bars D.

In the drawings a central thrust-bar D is shown in addition to end bars, which bars prevent buckling of the mold-board when the latter is of great length; but in cases where the mold-boards are short the central thrust bar may be dispensed with. When the mold-boards are assembled one upon the other, the backing timbers are supported vertically by spacing-blocks II, inserted between said backing-timbers, or the blocks may be fast to the latter, if desired. To hold the mold-boards in position with relation to the side of the building, so that an even thickness of cement may be applied, a pair of posts I are utilized, said posts being driven into the ground to the rear of the backing-timbers and having pivoted thereto evener-beams I, which are arranged to abut the rear edges of said backing-timbers. The evener-beams are hung between plates J, secured to the ends of the posts by means of pins K, projecting into slots of the plates, the upper ends of said beams being adjustably tied to the building by rods L in hook-and-eye connection there with, the outer ends of which rods pass through the aforesaid beams and are threaded for the reception of hand-nuts L, as shown. The lower ends of the evener-beams are guided between straps M, extending from the posts, and are engaged by adjusting screws 'N, which pass through said posts, there being rub-plates O secured to the beams against which the screws abut. Each moldboard at its bottom edge is provided with a depending metal facing edge P, to which is secured a beveled print-strip Q, there being similar cross-strips Q suitably spaced apart to form indentures in the cement to simulate blocks, the upper face of the mold-boards being recessed for the reception of edge P of the next adjacent board.

In operation the supporting-post being in position the face of the first mold-board, as shown, is set the required distance from the building for the thickness of cement, with the print strip Q slightly embedded in the ground. When in this position, the evenerbeam is adjusted against the backing-timber and parallel with the building-wall by means of its upper and lower adjusting devices. The apparatus when set as above described is ready for receiving the cement, it being un derstood that end filling-boards R, as shown, are secured to the building at the ends of the mold to prevent said cement from flowing out between the mold-board and Wall. Previous to pouring the cement, however, the backing-timber is pressed. downward, thus rocking the mold-board on its edge resting upon the ground until the face of said board is at a slight angle to the wall. The cement is then poured until it reaches the level of the mold and another mold is put in position. The lower or first mold is now straightened up, the surplus cement thereby being IIO squeezed upward into the space made by the mold-board just added, and so on until the entire sectionv has been completed, at which time the evener-beam may be again tightened up parallel with the building-wall and the apparatus left until the cement has set, when it can be removed and another section started.

I claim 1. A mold for forming cement facing for building, comprising a series of frames carrying mold-boards and adapted to be stacked one upon the other, and horizontally-adjustable supports in connection with the building for holding said mold-boards in place.

2. A molding apparatus for forming cement facing for building, comprising a series of mold-boards adapted to be stacked one upon the other, in combination with supporting-posts for the said mold-boards, vertical bars hung upon the posts, adjusting means in connection with bars and building,

and other adjusting means in connection with said posts and bars.

3. A mold-board provided with print-strips upon its face, a backing-strip therefor, bars connecting the backing-strip and upper edge of the mold-board, and braces in connection with said bars and the lower edge of said mold-board. I

4. A molding apparatus for forming cement facing for building, comprising a series of frames carrying mold-boards adapted to be stacked "one upon the other, spacing-blocks interposed between the frames, and horizontally-adjustable supports for said frames.

In testimony that I claim the foregoing I I have hereunto set my hand, at Cambria, in

the county of Columbia and State of Wisconsin, in the presence of two witnesses.
