Specification of Letters Patent.
Patented Feb. 1, 1921.
. Application filed November 26, 1919. Serial No. 340,848.
To all whom it may concern:
Be it known that I, Bonner TANNENBAUM, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements inConcrete- Forms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings forming a part of this speclfication.
My invention relates to concrete forms, and has for its principal Object the provision of forms for the pouring of concrete in the construction of foundations and other struc tures, of such a nature that the same may be readily assembled and taken down with a minimum of labor, and which may be used repeatedly without depreciation or injury, materially affecting their availability for the designated purpose. a
A further ob 'ect of the present inventlon is to provide in concrete forms, separate boards or members having cleats for convenient assembly.
Another object is to provide boards or members for the construction of concrete forms having beveled edges whereby the seepage of concrete is permitted to drain from the edges of the boards, thus obviating the necessity for cleaning the boards after each use.
'A still further object of this invention is to provide in a concrete form, constructed of a plurality of boards, expansion members, whereby the expansion or swelling of the boards may be accommodated, and the concrete structure relieved of any strain there from.
Anotherobject of the invention is to provide in a concrete form, boards or members, which are adapted for assembly or use as a concrete mixing board. e
Furtherobjects of the invention Wlll appear from the following detailed description thereof. a
In the drawings 1 1 Figure 1, is a perspective of a portion of a concrete form constructed in accordance with the present invention.
Fig. 2, is a perspective ofone of the boards 1 or members.
Fig.3,is a perspective of one of the expansion members. a a Fig. 4, is a perspectlve of a number of the form members assembled for use as a mixingboard. 7
The numeral 1 indicates timbers of desired dimensions which are disposed longitudinally in pairs along the sides of the proposed structure, and the intersections spiked together as shown at 2. In order to accommodate the dimensions of the proposed struc ture, the timbers may be overlapped, if necessary, as shown at the top in Fig. 1. The walls of the form are constructed of form boards or members 3 onthe back sides oi each of which is a plurality of angularly dlsposedj cleats 4. The cleats 1 are so disposed thateither end of the boards or members 3' may be uppermost, and the cleats will overlap the boards and be in contiguous relationto each other as clearly shown in Fig. 1 of the drawings. When assembled, the cleats hold the boards in alinement so that the inner wall 5 composed of the assembled boards, presents a smooth plane surface. The boards are nailed to the longitudinal timbers 1. At 1 suitable intervals, the two walls or sides of the form, are, as is customary, held together by means of wires 6 which are looped about the timbers 1 and extend between contiguous boards'of the two walls ofthe form. The edges 7 of the boards 3 are beveled, as shown, to the rear, so that the contacting edges 8 of the boards are relatively sharp, and the boards'may thus be compressed tightly against the wires which slightly indent the thin edges 8. To the rear, the adjacent beveled edges 7 of the boardsleave a crevice or vertical crack 9 for the purpose hereinafter set forth.
In connection with the members or boards 3, I provide expansion members 10, each comprising a thin front plate 11 made of sheet metal or other suitable material, and a back rib or stiffener 12, secured to the plate 11 by anysuitable means. The rib 12 is of the same thickness as the members or boards 3. Pivotally secured to the back of the rib 12 is a elect, or cleats, 13 which is adapted to be rotated to lock the expansion member to boards 3, as shown in Fig. 1 of the drawings, in which position the rib 12 is laterally removed from themembers 3 at each side of the expansion member. I employ expansion of the drawings, I have disclosed a window frame positioned in the wall.
The nature and use of the present invention will be clear from the foregoing description. In ordercto construct a concrete form, the timbers 1 are longitudinally disposed on the sides of the contemplated structure for both inner and outer walls of the form. Between the timbers, the walls of the form are formed by means of members 3 disposed and interlocked by means of cleats 4 as above set forth, the members being also nailed to the timbers. At suitable intervals, wires 6 are used to maintain the two walls of the form in proper relative positions, the wires 6 passing between contiguous boards in the opposite walls, and being looped about the timbers as shown. For this purpose, it is necessary that the joints between boards be approximately opposite and in order to accomplish this, if necessary, one or more expansion members 10 may be employed, as it is obvious that members 3 maybe displaced at suitable distances to accomplish this result from the stiffening rib 12 of the expansion members. In order to prevent the cracking of the concrete wall when poured at the corners by the lateral extension of the forms through swellings when they become wet, I also provide expansion members 10 in each wall in each side of the corner. These members permit the boards 3 when expanding, to slide at therear ofthe plates 11, as in origlnal placement the edges of the boards 3 are displaced from the ribs 12. This preventsthe expansion of the boards from forcmg outwardly theconcrete of the wall at the corners, and thus prevents cracking. Be-
tween contiguous boards, the crevices 9 permit free, passage for any seepage downwardly, and it is not caused to adhere to the edges of the'boards as is the case where such seepage is compressed between contiguously disposed parallel surfaces. The thin edges 8 also caused by the beveling of the edges of the boards, permit the wires 6 to be embedded in the edges, and thus admit of the contiguous placing of the, boards without any cracks or openings between the same. As shown invFig. 4, furthermore, the members 3 may be assembled for use as a mixing board.
