L. WALL FOUNDATION CONSTRUCTION INVOLVING BLOCK HAVING MORTAR RETENTION MEANS Filed May 16, 1966 2 Sheets-Sheet 1 INVENTOR LYLE E- WRIGHT im nmmm ATTORNEY WRIGHT TRUCTI May 9, 1967 L. E. ON CONS I LVING BLOC O A EANS WALL FOUND HA G MORTAR RE'I'E 2 Sheets-Sheet 2 Filed May 16, 1966 INVENTOR [we Tn/e/aA/r QM ZT FERNEY United States Patent WALL FOUNDATION CONSTRUCTION INVOLV- ING BLOCK HAVING MORTAR RETENTION MEANS Lyle E. Wright, Lanham, Md., assignor to Universal Building Products Corporation, Washington, DC. Filed May 16, 1966, Ser. No. 557,852 2 Claims. (Cl. 52169) This application is a continuation-in-part of application Ser. No. 406,689, filed October 27, 1964, now abandone-d.

This invention pertains to wall constructions formed of blocks made from aggregate materials, such as cinder blocks, cement blocks, and the like, wherein the wall is of new and novel decorative form and is of an improved, substantially waterproof construction.

The basic object of the present invention is to supply a block for use in a wall construction, the block being of a construction such that adjacent blocks are adapted to meet in edge to edge contact insofar as all visible portions are concerned while, at the same time, the blocks are provided with improved mortar joints.

Another object of importance resides in the provision of blocks for use in a wall construction wherein the mortar joints of the wall are concealed and protected.

A further object of the arrangement hereof is the provision of a block with side and end edges arranged for flush contact with side and end edges, respectively, of adjacent blocks forming enclosures about the mortar joints of the block, thereby rendering the wall construction virtually impregnable to the passage of water or moisture therethrough.

Yet another object is to provide decoratively faced blocks meeting in close edge to edge contact, to provide a minute and inconspicuous joint therebetween-giving the effect of a monolithic wall surface. In this respect, the invention provides an effect similar to that provided in my prior copending application Ser. No. 393,893, filed Sept. 2, 1964.

An additional and related basic objective hereof con cerns the provision of levelling means for insuring the level horizontal alignment of the initial course of a wall construction. In the formation of special block configurations, previous proposals have been objected to on the basis of difiiculties involved in the levelling of the first or base course of a series thereof. It is therefore an objective of this invention to supply a means to insure initial course levelling.

A further object is to provide a wall construction wherein mortar joints between adjacent block courses are encased by the block whereby the block courses are supported on underlying courses during erection of the wall, as opposed to conventional systems wherein the courses rest on underlying mortar joints. In the absence of weight bearing on the mortar joints, improved strength characteristics of the finished wall are achieved, and the walls may be constructed to any selected height without delay for curing of the joints.

Additional objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawing, in which:

FIGURE 1 is a perspective view of a portion of wall construction in accordance with the present invention;

FIGURE 2 is an enlarged perspective view of one of the blocks hereof;

FIGURE 3 is an enlarged, longitudinal cross section, taken substantially on the line 3-3 of FIGURE 1, looking in the direction of the arrows;

FIGURE 4 is a vertical cross sectional view taken on the line 4-4 of FIGURE 3, looking in the direction of the arrows;

FIGURE 5 is a sectional view similar to FIGURE 4, showing a modification;

FIGURE 6 is a fragmentary perspective view showing a footing excavation and disassembled levelling apparatus hereof;

FIGURE 7 shows the elements of FIGURE 6 following pouring of the footing, and indicates the placement of an initial block thereon;

FIGURE 8 is an enlarged sectional view on the line 8-8 of FIGURE 7, looking in the direction of the arrows; and

FIGURE 9 is a detail sectional view onthe line 9-9 of FIGURE 8, looking in the direction of the arrows.

Proceeding to a more detailed description of the invention, the block hereof is generally designated in the drawings by reference numeral 10, and the block is best shown per se in FIGURE 2. The block, for purposes of description, includes a main block body portion 12 having substantially flat upper and lower sides 14, 16, respectively. The blocks preferably have a plurality of cores 18 formed therein which extend from the upper sides 14 to the lower sides 16 thereof.

The block body portion 12 further includes opposite ends 20 and 22 of generally flat form, arranged substantially perpendicular to the sides.

Forward and rear facing elements 24 and 26 are fixedly secured (preferably by integral formation of the blocks as monoliths), to the main block body portion 12 and the facing elements are of enlarged dimension relative to the portion 12 and extend outwardly of the sides andends thereof. Each element may, if desired, be decoratively coated as at 28, and each has upper and lower side edges 30, 32, and end edges 34, 36.

The edges 30 and 32 of the facing elements project outwardly from the sides 14 and 16 and thus form flanges 38 with inwardly facing walls 40. The walls 40 and the sides 14 and 16 define mortar retention troughs 42 along the upper and lower central block areas in a course thereof.

The facing elements further extend outwardly of the ends 20 and 22 of the blocks whereat they comprise flanges 43 of increased depth as indicated at 44 with inner walls 46. The inner walls 46 and ends 20-22 define mortar retention pockets 48 at the central end areas of the blocks.

As shown in the drawings, the blocks are adapted for employment in a wall construction W or the like, installed on a surface S. In such arrangement, the blocks 10 are placed in courses C which may be staggered. With the blocks in position, the mortar M occupies the troughs and pockets, but is concealed from view and protected from moisture and otherwise by the flanges 38 and 43. The end and side edges of the facing elements are in close contact and present an appearance of a monolithic structure to all but the closest inspection, and in fact, this close abutment of the end and side edges prevents the intrusion of moisture into the wall and into contact with the mortar M.

In FIGURE 5, a modified form of the block is disclosed. In this embodiment of the invention, the upper side is flat and uniplanar. As seen in the drawings, the uniplanar side is arranged adjacent a flanged side to provide a mortar pocket. The provision of a pocket with one flat, uniplanar side permits manufacture of the blocks in certain types of machinery wherein such feature is a requirement.

In the formation of walls employing blocks 10 of the type hereinbefore described, it is quite important that the surface S on which the blocks are to be installed be level (or that the first course be levelled). In order to provide an initially level footing, the present invention includes a means for levelling of a footing during its installation. This means includes a plurality of grade stakes 200 each having a generally flat top side 202 and preferably sharpened at its lower end 204 to facilitate the driving of the stakes into the ground. The stake top sides have central slots 206 therein extending the full length of the top for a purpose appearing below.

Further included in the levelling means is a plurality of levelling plates 208 each comprising an elongated plate 210 formed preferably of metal or the like. Each plate has a central, longitudinal, depending crimp section 212, and side flanges 214, 216. As indicated in the drawings, the plate is dimensioned to overlie the top side 202 of the stakes, with the crimp 212 occupying the slot 206 and the flanges 214, 216, being engaged about the sides thereof.

In the use of this apparatus, an excavation 218 is first formed at the described location of the footing. Stakes 200 are then driven into the ground at the approximate center of the footing at longitudinally spaced locations. The tops 202 of the stakes are thereafter levelled with respect to one another as indicated in FIGURE 6 wherein, by way of example, a line 220 is extended along the top of each stake, and the stake tops are then driven into the ground to an extent such that a levelling device 222 indicates that the desired level coalignment of the tops has been achieved. With the stakes thus levelled, plates 208 are connected thereto at required intervals to form an uninterrupted series thereof, nails 224 being driven through the erimps 212 and into the stakes to effect connection thereof. Thereafter, the level of the plates is again checked with a suitable instrument such as the spirit level 222, and the aggregate material for formation of the footing block is poured. Any flat tool of appropriate size is thereafter used to strike the aggregate level with the top 210 of the plate, and the finished footing 226 is thus levelled with the previously levelled top of the string of plates. This provides a top surface 228 for the footing to which the blocks 10 or 100 may be applied directly without additional levelling.

Having described and illustrated several embodiments of this invention in some detail, it will be understood that this description and illustration have been offered merely by way of example, and that the invention is to be limited in scope only by the appended claims.
