CONCRETE-FORM.
Specification of Letters Patent.
Patented July 18, 1916.
Application filed April 23, 1910. Serial No. 557,280.
To ZZ H'm m it may concern Be, it known that I, EDMUND BECKER, a citizen of the United States, residing at ll'vasliiiigtoii, in the District of Columbia, have invented certain new and useful Improvements in Concrete-l `orms, of which the following is a specification.
My invention relates to a novel type of mold or forni to be used in casting monolithic concrete walls, and it consists in a special combination and arrangement of mold parts adapted to permit of the extensive use of externally and lightly tacked but otherwise solidly supported frame members, in combination with a plastered and smoothly trowelcd porous niold lining to be built and finished in position of use, but before coinpletion of the opposite heavier lining which is finished last and held in place by external tacking. The framework is, moreover, combined to facilitate the lathing and plastering operations and so as to permit ot very extensive use of externally and only partly driven nails or so-called "tacking so as to injure the lumber as little as possible, saving it for future use and greatly facilitating the process of forni removal, which is already considerably simplified by the use of the easily destroyed plaster lining. Projecting nails cannot, of course, be used .inside of the mold, hence the necessity of using a special construction the permits of using relatlvely weak and externally driven fasteners.
(lne preferred form of my invention, 1n which over ninety five )er cent. of the frame fasteners are externally and only partly driven nails, all other fasteners being bolts, is illustrated in the accompanying drawings, in which:
Figure 1 is a horizontal section of a form showing front plaster lining and rear plank lining D, the plane of section belng at the level indicated by 1plane 1 to 2 runnlng horizontally through igs. 2 to 5. Flg. 2 is an outside elevation of a part of the front wall as seen looking in the direction of arrow I in Fig. 1. Fig. 3 is an inside elevation of a part of the front unplastered lathing as seen looking in the directlon of arrow II in Fig. 1. Fig. 4 is an external eleyation of a part of the rear wall as seen lookmgm the direction of arrow III in Fig. 1. `1g. 5 is an internal elevation of a part of the rear Wall as seen looking in the direction of arrow IV of Fig. 1. Fig. 6 is a perspective View of a plank lining tacked by hasps to the posts and studding. l 1g. 7 shows one of the planks with the hasps hinged in order that they may be flattened down for transportation and storage. Fig. 8 shows a horizontal section of Fig. 9, and Fig. 9 the perspective View of a wall with a portion lathed and plastered. Fig. l0 is a pers ective View of the framing as it appears be ore any lining has been applied. Fig. 11 is a Vertical transverse sectlon of the form showin the front plaster lining C, the rear plank llning D and a part of the cast wall A, all externally tacked nails, that is to say, nails that are only partly driven being indicated by t.
Referring to Fig. 10, sills W, spaced the desired distance apa rt, are placed on the footing V. Upright members, or main posts, E are erected and stayed (stays not shown), and united by temporary spreader-ties F. These ties, Fig. 11, are prepared in lots ready-bored with a series of suitably spaced holes for bolts f, to provide beforehand for the different standard wall thicknesses or standard depths of forms. The Stringer planks G, are then tacked to the upright members E and the intermediate upright members, or filling studs, H are spaced and tacked to Stringer plank G at their proper places. The Stringer, or wall piece, I, resting on spreaders F is then secured to the upright members E by tie-bolts K inserted through the upright members E. The framing being completed, the next step is to line the form having due regard to the desired finish to be obtained. By reference to Figs. 2, 3, 8 and 9 the various steps in finishing a form in order to obtain a smooth or ornamental surface are disclosed. The upright members E and H are lathed` with metal or wooden laths Z which consitute the preliminary lining of the front or finished Wall of the form, and is designated by C in Fi s. 2 and 3. The laths are then covered or lined with a coat of plastic material troweled smooth or finished in the desired ornamental design as indicated by L, Figs. 8 and 9. The construction of a form as thus described allows me to retard the setting of the surface of the concrete after pouring in a quick, effective and economical manner by playing a hose on the back of the lathing, thus soaking the plastering of the form, which,v being somewhat porous and permeable, absorbs and distributes the Water evenly on the surface of the concrete. This result cannot be obtained by the use of Wooden lagging, as the moisture would not be evenly distributed and would ultimately deform and destroy the wood.
The best and least expensive method of obtaining a rough finish is b v the use of a plank lining D` as shown in Figs. 4. 5 and 6. a detail of the plank M being shown in Fig. 7. The planks should be planed to the same thickness and the edges trued so as to superpose tightly to prevent the oozing of the concrete through the joints. and are secured to the upright melnbers lil and Il. Fig. t, by means of hasps b. Fig. 7. one leaf of which is securely fastened to plank M and the other tacked to the upright members ,E and H. These planks are used in their entire length as purchased and are interchangeable and continuous. In actual practice I have found that the edges of the planking described may be packed with felt instead of being trued as mentioned above. It may be remarked in this connection that the linings and I) just described add greatly to the strength and rigidity of the form` Figs. l. 4 and 5 show the upright members of the back wall spaced at greater intervals than those of the front wall because of the greater stiffness of the planks l\. and at the same time this construction allows easier access to the plasterer into the form for coating the front wall and also to the concrete gang for pouring the concrete. the rough planking being put in place only as the filling progresses. As the work progresses upwardly. the function of the spreader tie is performed by the concrete filling so that when the level of such filling comes close to such a tie as shown in Fig. 11 the tie is removed. 'hen the concrete in the forms has set, the tie-bolts K are unscrewed. the Stringer. or waling piece, I lowered, the upright members released from stringer plank (ir, whereupon the upright members of the form. together with the lathing and plastering of the front wall. fall away from the finished face. leaving the wall perfect and free of' blemishes. the holes lay left by the tie-bolts l( being filled with concrete of the right grain and color while deforming.
I claim:
