1 Claim.

The V.present invention relates to an improved building unit, the purpose lbeing to provide a unit ,tov be supplied with a beautiful glossy surface,'r,esembling polished granite, marble or the like, theglossy or glazed surface acting to render the unit ,damp 'and moisture-proof.

Anotherrpurpose is .to provide a unit, together with a process for imparting to the face of the unit al highly polishedV surface, by constructing vglazed element can be removed from the unit, l leaving the face of the unit polished or glazed.

Still another purpose is to provide any suitable glazed elements, such as glass, highly polished brass, copper or other polished metals, or

`any element which may be or can be given a polished surface may be used in the mold for imparting a polished or glazed face on the unit, or such metal as may be given a polished surface by the application of chromium.

It is well understood that the usual standard mold for making building units has its interior surface rough, hence the reason for using polished inserts. Furthermore though a mold may have its inner walls polished, such molds would be more -or less expensive, and moreover when the unit is allowed to set in the mold, the air would not so easily enter between the inner faces of the mold and the unit, such as would enable the sides of the mold to be opened without defacing the surface of the unit. Such a method of imparting a polished surface to the unit may be used but such a method is not as practical, and furthermore considerably more expensive, than where glass inserts are used on the interior of the mold.

It is to be understood that the particulars herein given are in no way limitation, and that molding a unit with polished or glazed surfaces.

Figure 2 is a longitudinal sectional View on line` 2f-2 of Figure 1. f

Figure 3. is a perspective view of the unit after it is removed from the mold, with the glazed insertions or elements vattached to the unit, showing the unit in the process of setting orvcuring., l Figure 4 is a perspective View of the unit com,v plete, the polished 'insertions r`or elements havingv been removed, the unit thoroughly set, a glazed or polished surface having been imparted to portions cf the different faces of the unit.

Figure 5 is a view of a standard type of mold, showing an insert with its interior polished, so that the unit may be molded with polished faces.

Figure 6 is a longitudinal sectional View on line 6-6 of Figure 5.

Figure 7 is a detailed View with the rectangular insert removed.

Figure 8 is a detailed View of the unit constructed in the manner shown in Figures 5, 6 and 7.

Referring to the drawings, 1 identifies a mold of any standard type which may be suitable for this purpose, and wherein the sides and ends are capable of being opened, though they are not shown as opened, and 2, 3 and 4 identifies insert slabs or pieces of highly polished glass or other elements, which may be highly polished.

In the molding of the unit these slabs or insert element highly polished are arranged adjacent the bottom, sides and ends 5, 6 and '7, the slabs being beveled on their edges as shown at 8, though not necessarily, so as to enable the slabs to fit together in position. After so arranging the slabs, with their polished faces 9 inwardly, sufficient semi-liquid cement consisting of finely pulverized sand, cement and water in -a plastic condition is deposited in the mold, on the bottom slab and on the inner faces of the side and end slabs, as identied at 10. This semi-liquid cement, nely pulverized sand (better known'as silica flour) and water with the addition of lime aggregates, and pigments in order to color as desired, when thoroughly set will receive on its outer faces highly polished or glazed finish, due to the glass or other slabs.

However, after applying this liquid cement, finely pulverized sand, water and the lime, the mold is filled with a courser cement to make up the body of the building unit, such cement being thoroughly tamped so as to adhere to the first deposit.

After the unit is so molded, the mold may be opened and the unit removed and allowed to set the required time, for example anywhere from ten to twelve to fifteen days. After the unit has thorcsf:

oughly set, during which time air is allowed to enter between the slabs and the face of the unit (which enables the slabs to more or less loosen) the slabs are removed, thereby in this manner imparting to the face of the unit very highly polished finish.

Referring to Figures 5 to 8 inclusive it will be noted that a rectangular member 11 is inserted in the mold instead of the slabs. In other words this rectangular member performs the same func- -Y tion as the slabs. The fact is the bottom of the member constitutes the bottom sl-ab while the sides and ends of the member correspond to the insert slabs at the sides and ends in Figures 1 and 2, the only difference being that the corresponding parts are integral.

After the rectangular member is inserted in the mold the semi-liquid material is deposited in the mold against the inner face of the sides, ends and bottom of the rectangular element, suioiently to build up a face portion of the unit, said material being identified by the numeral 12. Subsequently to depositing the semi-liquid material in the rectangular member, the mold is lled with the courser cementitious material or concrete, so as to complete the body of the unit.

The inner surfaces of the sides and ends of the rectangular member are slightly inclined so as to permit this member to be more easily removed from the unit after it is once set. This rectanguedl lar member may be made of glass, or any other material such as polished metal of any kind.

In either case when the unit is finally complete, it is provided with a polished face and polished sides and ends, there being a ridge `or shoulder 12 along the sides and ends.

After the unit is thoroughly s et the rectangular member may be removed or the slabs removed eaving the faces of the unit'polished.

`The invention having been set forth, what is claimed is:

A building unit, comprising a unit body consisting of a major stratum constituting the larger portion of the unit, and composed of relatively coarse cementitious material, and a minor stratum extending over one entire face of the major stratum and substantially one half Waydown on two Vopposite sides and the two opposite ends, said minor stratum being composed of extremely ne grade of cementitious material, a simultaneously produced bonding between the two strata, the major stratum at pointsY where the minor stratum terminates on the two sides and ends having a beveled shoulder, whereby when a number of units are used in a wall construction with the ends and sides of the major stratum in contact, the sides and ends of the minor stratum of the various units are spaced, said minor stratum on its face, sides, and ends having a highly smooth finish.
