PROCESS OF FORMING CONCRETE WALLS SPECIFICATION forming part of Letters Patent No. 640,653, dated January 2, 1900.
Application filed October 30, 1897. Serial No. 656,981. (No specimens.)
To all whom it may concern.-
Be it known that I, CHARLES GUY, of Topeka, in the county of Shawnee and State of Kansas, have invented an Improved Process for Forming Monolithic Concrete Structures or WValls, of which the following is a full speoification.
In the accompanying drawings, Figure 1 is a vertical section illustrating the application of the mold for forming a vertical wall. Fig. 2 illustrates the application of the same for a horizontal surface or wall. Fig. 3 is a view showing the application of the invention to archwork.
My invention has for its object to mold concrete walls, ceilings, arches, piers, or other monolithic structures in an improved manexcept by an after coating, which destroys the monolithic feature.
In the drawings C indicates a sheeting or rough board face for a skeleton frame or crib 13, having a brace A. Upon such face 0 is plastered a layer of staff, lime, gypsum, or any plastering material of suitable strength, set ting qualities, and consistency for the purposes hereinafter mentioned. After this plaster has hardened its exposed surface is covered with cheese cloth or other similar cheap, strong, and open-grained fabric, held 011 by paste of flour or other suitable material. The monolith is then constructed, and after it has been given ample time to properly harden or set the structure A, B, and O is removed. The staff or other plaster D, having been made barely strong enough to resist the compression coming against it from the ramming or tamp ing of the concrete, but not having any trans verse strength, now falls to pieces, and the cloth is readily pulled off of the concrete, leavin ga'handsome granular finish,which is not obtained by the oiled or oil-papered forms. The
lar surface in artificial stonework is a better imitation of stone and a richer appearance. The forms may be and often are built of galvanized-sheet-iron, zinc, or other metal instead of lumber. The plaster and cloth are then applied to the metallic form. In any case the plaster needs to be only thick enough to thoroughly cover all roughness of surface of the form to which it is applied. When a long wall or cornice or any large surface is built, a lap of muslin, one piece upon or over another, leaves no visible sign of such lapping, and the plaster covers all joints where one mold is slipped ahead of another, so that the highest effects in finish are by this means obtained, while with oiled Wood or oil-paper the laps or joints almost invariably show in such manner as to be unartistic and objectionable.
If a wall has a coping or has buttresses or ofisets or if a ceiling or cornice has in section numerous renterin g angles, reversed curves, or other irregularities, the cheese-cloth fits them all, and even if it is doubled over itself it is just as effective as on a plane surface.
I claim and desire to secure by Letters Patcutwall for architectural purposes, the same consisting in erecting crib or other structure having' a; face corresponding to the desired form fabric, with adhering pl aster, of? the coficrete' CHAS. GUY; Witnesses:
