APPARATUS FOR MAKING CONCRETE WALLS.
SPECIFICATION forming part of Letters Patent No. 768,376, dated June 28, 1904. Application filed September 30, 1903. Serial No. 175,215- (No model.) f
To all whom, it may concern.-
Be it known that I, HERMAN Born, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Making Concrete Walls, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
The object of the present invention is to provide a cheap, effective, and improved apparatus for making concrete walls.
This invention is particularly well adapted for building dams and other like heavy work, as will hereinafter be more fully shown and described, reference being had to the-accompanying drawings, wherein Figure 1 represents a plan view of a wall under construction employing the use of my apparatus. Fig. 2 is a side elevation of the wall, showing the upright posts, mold-boards, and supporting-irons. Fig. 3' is a sectional View of the wall, showing the manner of placing the supporting-irons and their relation to the molding-hoards and upright posts, together with the binding-piece at the top, when applied to a straight wall. Fig. 4: is a view of my supporting-iron, showinghow the one end is bent to retain the upright post and the other to form an anchor when placed in the wall. Fig. 5 is a sectional view of a wall with succeeding steps as the wall becomes higher, showing the relative location of the parts with reference to the supporting-irons.
In making concrete walls I use my supporting-irons and proceed as follows, using similar letters to refer to similar parts wherever they occur on the different parts of the drawings.
The foundation of the wall being laid, I proceed by placing one of my supporting-irons A near the surface of the ground, sufiiciently spaced to receive the vertical posts B B and the molding-boards O C. The supportingbracket is then covered with concrete and left until the wall is sufficiently strong to retain the iron and the load it is designed to carry. This being accomplished, I place the upright posts B B in position and bind them at the top with the binding-piece D, which is notched on the under side at d to receive the top of the upright posts B B. The molding-boards C C, 1 place as the height of the wall requires to hold the concrete in position until it is set. These molding-boards can be secured to the posts B B in some suitable manner and handled in sections, using any number of boards desired in a section. The running-boards E E, I place in position last, which can be held in place temporarily by nailing to the binding-pieces D. This being accomplished, I begin filling the space between the moldingboards C C with concrete. Before the space between the supporting-irons A A and the binding-piece D is filled with concrete I place another set of supporting-irons at G G and fill in around and above the brackets placed last to the top of the molding-boards G C. The brackets that I place last serve as a support for the centering pieces for the next section of the wall, thus enabling me to build any height of wall without the use of bracing from the ground.
Fig. 5 shows the parts assembled in operative position when building walls with successive offsets as the height increases.
The wall having reached the height at which the offset is to be placed, the supportingbracket A is put in position. A part of the body of the bracket is so placed as to beunder the immediate surface of that part of the wall forming the step and located with reference to the rise of the wall so that the distance from the outer vertical part of the bracket to thewall is equal to the width of the post B plus the thickness of the boards 0 (J.
The bracket or supporting-iron I make of a suitable length, width, and thickness and forge the outer and inner ends (with reference to their place in the wall) such that they will stand at right angles to the body of the bracket, thus making one end a retaining-leg for the upright post Band at the other an anchor that when set in the concrete will not be easily removed.
In this manner of building concrete walls I bedded in the wall, vertical centers or posts held at their lower ends upon the outer portions of the supporting-irons, mold-boards supported at the inner sides of the vertical posts, and binding-pieces connecting the vertical posts at the top and interlocked therewith, substantially as and for the purpose set forth.
In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
