BUILDING CONCRETE WALLS.

SPECIFICATION forming part of Letters Patent No. 787,665, dated April 18, 1905.

Application filed March 19, 1904. Serial No. 198,883.

To n/ZZ whom it may concern:

Be it known that we, REED DEEDS and VIL- BUR C. DEEDs, citizens of the United States, residing at Cuyahoga Falls, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Building Concrete Walls; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to a system for building concrete walls; and the invention comprises suitable forms and molds and other parts for the erection and construction of the walls, substantially as shown and described, and particularly pointed out in the claims.

In the,vr accompanying drawings, Figure l shows a perspective view of a section of wall built up by our system and forms, molds, and other parts employed in the construction of the wall, as hereinafter fully described. Fig. 2 is a cross-section of a wall under construction and the inner parts to form the hollow in the wall in vertical section thereon; and Fig. 3 is a cross-section on line fr, Fig. 2. Fig. 4 is a perspective inner view of one of the supporting-planks with the angle-iron housing for the molds on its face and constiornamental stone, as well as to produce division-courses, window-sills, door-sills, window or door caps, moldings for cornice-work, inside tinish for door or window casings or moldings, base-moldings, plastering for walls and the like, all as will appear in the further description herein, it being understood that the wall and all the portions and parts above enumerated are molded n situ or directly into the building where they are to be used.

As shown in Fig. l, a suitable framework is used, comprising beams B, connected transversely by bolts or rods Z) and spaced apart laterally according to the thickness of the wall to be erected. Inside of said framework on opposite sides We place a suitable backing for the forms and molds, which may be built up one way or another, but shown herein as composed of a series of planks C set edgewise one upon the other and secured to said beams to form sustaining-walls within which the work is done. The said planks are of course temporarily in any given place and adapted to be moved here or there as the wall progresses and work is to be done on higher or lower levels on other portions of the building. Practically We plan to use up all prepared material with each days work, so as to avoid loss by hardening overnight, and one plan, further, is to so place these temporary walls about the building from day to day as to bring all sides thereof along as evenly as possible. Each of the front tier or series of supports C is equipped with suitable molding devices comprising the molds proper, D, and the mold-supports or separating walls or borders E, fixed to said planks. These latter devices are shown herein as of'angle-iron or stiff heavy sheet metal bent to form and of varying pattern, the same being purposely of different lengths and dierently arranged on lthe backing C, so as to break up the surface into diversified shapes and give the effect upon the finished front of a wall of natural stone of varying sizes. The side irons or walls are nailed or otherwise fastened to the planks C through their right-angled anges, and within the recesses or subdivisions thus formed we secure the molds D. Said molds may be of any suitable material, as above stated, and for tine work are preferably of sand tamped to firmness and closely fitted within the borders or Walls E at their several edges. Said borders or plates have beads or curled lips 3 at their outer edges to form the courses between blocks and assist in holding the molds in place, andboth the hori- Zonta] walls 2 and the vertical walls 4 vary in length according to the shape and size of block to be made. The face of the molds purposely is such as to give to the blocks F the effect or appearance of natural stone, which is promoted by using sand molds, as the cement takes up some of the sand and gives a stone effect; but they might be of any fanciful or figured design or plain, if preferred. In this instance we show a series of molds and the housings or walls therefor complete on a single plank, and said plank is adapted to be moved from one place to another in the work with the molds thereon; but we might build the molds across planks, if preferred, and move two or more planks together. The inner molds D', which provide the interior finish, are usually plain, but may also be fanciful, and are anchored by means of' plates 6, engaged on the edges of planks C and slightly bent inside to form locks for said molds. These or other suitable means for fastening said inner molds may be employed.

If a double or hollow wall be made, as in this instance, we employ a special movable core for such purpose comprising a set of side walls G of planks and of wedge shape from the top downward, and a pair of wedges H between said walls of wedge shape upward. A yoke or loop /L on the top of each wedge supports a bar or rod J, forming a handle for operating the wedges. The side walls or planks G are connected by yokes g across rod J. The wedges H also have longitudinal dovetail grooves 7a2 in their sides, in which are engaged the correspondingly-shaped heads of short bolts g in sides G, and said grooves terminate in the upper middle portions of said wedges with 'shoulders g2, which fix a limit for the depression of said wedges when the planks are to be released for removal. The two concrete walls F and F are bound together at intervals here and there by clamps, hooks, or bolts L or their equivalent. In this instance we employ clamps which are preferably of sheet metal struck up to form hooks at their ends; but they might be formed of other metal or material and in other design or pattern and serve our purpose and are molded into the walls so as to be permanent parts thereof. The planksor inner construction-walls G rest down on these clamps as supports and are spread laterally and held uniformly apart the right distance throughout by wedges H when said wedges have been drawn up to spread the walls to the hollow wanted. When the said parts are to be moved, the wedges are driven down to release side walls G and permit them to be raised, and said wedges and walls can be taken out or moved along together or separately. When a hollow or double wall is thus made and the other parts are duly in place, the material for making walls F and F can be poured or shoveled in and carefully tamped, if necessary, to make it compact and fill out the molds at both sides, and all the temporary walls can be raised or moved along as the work progresses to build up some other part of the structure.

Generically the temporary outer supports C built up with planks are referred to as walls or construction-walls, and the angle-plate formations thereon are the forms for the molds. Fig. 4 therefore illustrates a section or portion of the front construction-wall with forms for the molds thereon and complete in itself.

Obviously, if a single wall be erected the wedges H and inner walls Gr will not be used and walls I) and D will be brought nearer together.

lVhat we claim is- 1. In the building of concrete and like walls, a temporary construction wall comprising plain-surfaced supports, sheet-metal forms on the inner face of said supports and molds fixed in said forms, substantially as described.

2. The means substantially as described for constructing concrete walls, the same comprising suitable molds, a back support for the molds and metallic division-walls between the molds fixed to said back support and constructed to lock said molds in working position, substantially as described.

3. A temporary construction-wall for the erection of permanent walls for buildings comprising a suitablev fiat-sided support, forms fixed thereon having the outline of blocks of natural stone of varying sizes and a separate mold fixed in each form, said forms having one edge turned to bear against the edge of the mold, substantially as described.

4. In a system of building concrete walls,op positely-arranged construction-walls formed of' fiat-faced supports one above the other in rof the same plane vertically and a framework sustaining said supports, angle-iron forms fixed on the said supports and projecting inward therefrom, and molds confined in said forms, substantially as described.

5. In concrete and other wall constructions, a set of oppositely-disposed constructionwalls, separate removable metallic forms fixed to said walls, and separate removable molds in said forms, in combination with parts to form a hollow space i-n the wall, said parts comprising oppositely-disposed wedge portions, substantially as described.

6. In the construction of hollow buildingwalls, fiat-sided outer construction-walls, forms fixed on the said walls and molds to give shape to the product confined in said forms, in combination with double-sided inner wedge-shaped construction-walls, wedges to spread said construction-walls laterally to the Width of the hollow the Wall is to have, and in combination With mold-blocks secured by means to raise and support the said Wedges in said forms, substantially as described.
