` Application filed July 2l, 1905. Serial No. 270,659.
Be it known that I, COLONELv ELLswoRTH -RUSSELL, a citizen of the United States, and a resident oi' Chicago, in the county of Cook and State of Illinois, have invented an Improved Apparatus for Forming Concrete Walls, of which the following is aspeciiication.
The construction of cement or concrete walls has become very extensive.
My invention relates to improved means for building such walls and is embodied in the construction, arrangement, and combination of parts hereinafter' described, reference being had to the accompanying drawings, in Which- Figure 1 is a perspective View of a concrete wall with my improved apparatus applied thereto in the manner required for building a wall. Fig. 2 is a plan view of the apparatus in place upon a Wall, the side air-space in the latter being also shown. Fig. 8 is a perspective View of the core-box employed to form the side air flue or passage.v
'A indicates the sides or side boards comprising the main portion or body of' a molding apparatus for forming a vertical -wall. As shown in Figs. 1 and 2, these side boards are arranged vertically parallel, the distance apart corresponding to thethickness of the wall to be formed. They are secured in this position by means .of bolts B, which pass transversely through them at points removed from the lower edge. The apparatus composed of these parts A B is 'shown applied -to a portion of a concrete wall already formed, the bolts resting upon the top of the wall, and thus supportingthe said boards A in the required position. portions of the boards which extend below the bolts B are in contact with the sides of the wall, and the nutsl being screwed up on the threaded bolts, the boards A are held in tirm contact with the wall, and thus supported vertically parallel, as required. In brief, when thus placed the boards A form practically a trough adapted to receive and be filled4 with concrete, which thus forms a vertical extension of the wall. It is to be understood that the length and width of the boards A may be varied according to the conditions, but that in any case the bolts will pass through the boards at points far enough above their lower edges to afford the boards'a due bearing on the sides of the Vertical wall, since by this means the boards are supported vertically when the bolts are tightened. The bolts pass loosely through It will be noted that thel perforations in the boards, and the latter may be provided with transverse braces or stien- V ing-pieces at such points.'
In order to form an air shaft or passage in the wall, I employ a core-box C, which is open on one side and is preferably contracted or beveled at the opposite inner corners, as shown in Fig. 3. This core-box is arranged in the trough or space betweeny the boards A with its open side against the inner board, and it is supported in place while concrete is being lled in by means which permit its ready detachment, a hook being pivoted to the upper-side of the box and adapted to engage a nail or screw a inserted in the upper edge of thel inner board. The hook not only serves to hold the core-box in place against the inner board, butprevents its falling down l into the portion of the air-shaft which may have been previously formed and yet permitting the core-box to be readily detached when required. The core-box C is placed in position after the boards A have been similarly placed on the wall, as illustrated in Figs. 1 and 2. Elongated core-boxes in the formof small rectangular tubes have been employed, the same being in practice set in the middle -of the space between the sides of the troughs;
but they require lto be removed in a few moments after concrete is filled in; otherwise their removal is rendered ditlicult or impossible by the setting of the concrete. By constructing and arranging a core-box asdescribed in this instance the box may be removed without ditliculty even when the concrete has set. The vertical air passages or shafts formed by the core-box applied in the manner described are on the inner side of the wall, and metallic laths are applied, so as to extend transversely across the passage, the saine beingsecured to wooden pegs or iron clasps inserted and secured in the holes in the wall which were previously occupied by the bolts B -that is tol say, when concrete has been lled into the trough' arranged as in Figs. 1, 2, and has duly set, the nuts b are removed from the bolts and the latter drawn out or removed from the boards and the concrete, leaving the boards free, so that they may be again placed in position and supported by the bolts upon the top )fy the last layer of concrete to receivefthef' next instalment. It necessary, the holes formed in the concrete by the bolts on the outer side of the .Wall may be lled in wi'th'concrete. By forming an air-space in theinner' side of the wall,
IOO
as described, I elect a saving in concrete, a saving in the time usually required for removing cores, facilitate the tarnping of the concrete layers in the trough, since there is more free space for use of tamping implements, and it is not necessary to hold the coreboxes in position manually. The core-boxes may also be removed much more easily and quickly than when constructed and arranged as usual heretofore and without destroying or affecting the setting and solidifying oi' the concrete, besides providing a larger air flue or space.
What I claim is- The improved wall-building apparatus herein described,comprising parallel boards spaced apart a distance corresponding to the thickness of the Wall, cross-bolts passing transversely through the boards at points above their lower edges, and having nuts applied thereto, the bolts serving to hold the said boards detachably connected and yet adapted for adjustment toward and from each other, the hollow core-box having its inner side open and arranged in Contact with one of said boards, and a device attached to the upper side of the core-box and engaging a pin set in the upper edge of said board whereby the core-box is supported detaehably and adapted for lateral adjustment with the parallel boards as required for walls of dilerent thickness, as described.
