METHOD F FORMING CEMENTITIOUS BLOCKS.
Application filed July so,
' This invention relates v.to methods of formin "cementitious blocks and particularly to' met ods for imparting an ornamental appearance to such blocks during formation thereof'.
lA11 Objectis to so utilize diiferently colored a cementitious mixtures in forming a 'building block or the like as to secure an ornamental mottled effect.
A furtherobj-ect is to obtain such an effect ,in a `sufficiently simple manner to avoid any considerablyincreased cost as compared to the production of plain blocks.
These and various other objects the inven- 15' tion attains by the construction hereinafter described and illustrated in the accompanying drawing, wherein: Figure 1 is a front elevation of a mantel made of my improv'ed blocks and illustrating one ornamental surface effect which may be secured by the herein disclosed method. Figure 2 is a perspective view of one of the blocks.-
Figure 3 is a detail sectional elevation of the block shown in Figure 2, and
-Figure 4 is a similar vsectionthrough a block having two faces mottled in accordance with myimproved method,
In practicing said method there isem- -ployed a mold formed of wood ,or any other suitable material and having any desired shape according to the contour of the block to be formed. Two or m/ore cementitious mixtures are employed differingin any desired manner as to color, but preferably otherwise comprising the same ingredients. The operator first scatters upon the bottom of the mold a quantity of one of said mixtures insulicient to cover said bottom and then similarly scatters upon the mold bottom a quantity of another mixture, differing in color. This alternate delivery of thetwo mixtures into the bottom portion of the mold is repeated until there -is formed a surfacing '45 layer A of material preferably varying from one-quarter to vone-half inch in thickness; The mold is'now'lled upy with cementitiousmaterial B regardless of color 4and preferably of cheaper ingredients, and its contents are then tamped to compact them to a suitable degree. If three or more mixtures are to be employed they are introduced 1927. seri-a1 no.l 209,538.
sprayin g.
v LBy mixing materials` in the described manner there is imparted to. that surface of the block which seats upon the bottom of the mold a ver pleasing ornamental effect rendering the lock particularly desirable for fire-place construction orn any other interior use.
Should it be desired to present my improvedv mottled ornamentation on two or more faces of the block, each' face may be covered separatelyy as above described and then held against the mold by a temporary partition wall while the mold is turned to bring another face to the bottom of the mold for receiving the mottling mixtures. The backing material may then be applied either before or after thetemporary partitions are removed.
In Figure 4 I have shown in cross-section a block made in this manner with two faces A1 and A2 formed by my improved mottling process and the backing material C reinforcing both mottled faces.
Vhat I claim is: I
The method of forming a mottled ornamental cementitious block, consisting of scattering promiseuously upon the bottom of a mold a colored mixture of cementitious material so as to partially cover said bottom, then promiscuously scattering upon said bottom a quantity of a differently colored mixture and repeating these alternate steps until the bottom port-ion of the mold is fully covered to a suitable depth, and finally lll.1
ing the mold with celnentitious material regardless of color.
In testimony whereofl I hereunto set my hand` MARTIN HOFFMAN.`-
