May 10, 1932. J. H. ALLES ET AL BUILDING WALL CONSTRUCTION FileffMay 1, 192g Ala? Patented May 10, 1932- UNITED STATES JOHN H. ALLEs AND GEORGE KoHL, E sfr. LoUIs, MISSOURI BUILDING WALL coNsfiEUcrIoNYAY 'Application filed May 1, 1929. SerialV No. 359,550.
Our invention relates to building walls and consists in a novel building block structure and assembly. u' u One of the most desirable, artistic and attractive forms of building walls is that having a front face formed ofrough stone blocks of irregular size and shape laid with broken joints both longitudinally and vertically of the wall. Due tothe Vscarcity of suitable l@ building stone in many localities and the increasing cost of quarrying and transporta- 'Y tion, the expense of a wall as described above is greater than the cost of a wall formed ot artificial stone'blocks7 but no artificial stone blocks have yet been produced which will simulate a natural stone wall of the Vtype referred toV abovevi. e.,' presenting a broken ashler appearance. j
One of the objects of our invention isto provide an artiiicial stone wall formed of blockshaving varying height and width and producing a broken ashler finish similar to that produced by roughstone.
Even when rough `natural stone has been used to form a wall face it has been customary to fill in behind the face stone with rough irregular stone or rubble and, in many instances, to dump sand and old mortar into the spaces, which practice results in a weak Another object of our invention is to provide artificial stone blocks of suiiicient depth to extend through the wall in which they are used from front to back ot` the wall,` each block having a'rough stone faceat one end and a smooth :tace at the opposite end and the side and top and bottom faces of the wallv also being smooth.
In laying a stone wall it is necessary `for the mason to trim many of the stones inorder to it them in between the adjacent stones.V This is a time consuming and expensive proc-v ess, and it is a further object of our invenming of the blocks in and unsatisfactory wall subject to deterioration to provide a series of artificial blocks of varying height and width which may be assembled after a predetermined design to produce a broken ashler nish without the necessity of any Vtrimming with the possible eXception of cutting the blocks to itaround window or door openings.
Another object of our invention Vis to provide in a wall of the type described a cor- Lner construction which will lend itself to 50 :forminga well bonded joint between two iiitersecting walls formed of the series of blocks referred to and without requiring any .triml order'to complete the corner construction. Thesey and other de- 05 tailed objects of ourinvention are attained Y in the structure illustrated in the accompanying drawings forming apart of the-specification 1n which:
Figiire 1 is an isometric view of an artii- 70 cialvstone wall showing one `corner thereof.
Figures- 2 and 7 are horizontal sections taken on the corresponding section lines of Figure 1.
. The corner blocks 1, 2 `and 3 yhave square ,7 bases, the width of blocks 1 and 3 being greater than the width of block 2 so that the sur- Jface presented by the three corner blocks in ythe direction of wall A is irregular.k Since blocks 1, 2 and 3 have square bases, thesur- 80 face presented in the direction of wall Bwill `be. identical with that presented in the direction of wall A@ At the side: of block. 1l arel two smaller blocks 4 and 5, the combined height of which plusthe layer of mortar 6 equals the height of block 1, but the widths of blocks 4 and 5 dier. f Y, f v i Above block 5. and overlapping the'joint' between the same and block 1 is block 7.and 90 above block 7 is a block 8 Lot" different height and width, the combined heights of 'block 7 andl block 8 plus the layer of mortar 9 equals the height of block 2.
Above 8 is a small block 10 and above'l to present irregular surfaces in the directions of both of said walls, the Vcontours of said surfaces being the same,V saidy corner blocks varying in their horizontal dimensions, and blocks eacli of greater depth than said corner blocks overlapping each other at the-rear of said corner blocks, certain of said blocks of greater depth overlapping the larger corner blocks, thereby binding the corner blocks with resp ect to each other and keying the two walls together.
3. In a wall construction, two walls intersecting to form ak corner, a series of corner blocks arranged one above the other and cooperating to present irregular surfaces in the directions of both of said walls, the contours of said surfaces being the same, and blocks each of greater depth than said corner blocks but of various heights up to height of corner 20 blocks, a block in one wall overlapping a block in the first layer in the other wall at the rear of said corner block, said block in the second mentioned wall overlapping a block in the second layer in the first mentioned wall at the rear of said corner block, said alternation in the overlapping of said blocks being carried to the top of the wall.
4. A building wall of preformed artificial stone blocks of a limited number of sizes assembled in a series of uniformly constructed units having a cruciforin outline disposed symmetrically about vertical and horizontal axes of the unit, successive units being in inverted relation to each other, and intermediate units of dumb-belllike contour cooperating with said cruciform units to form a continuous wall face the adjacent blocks of which are of diiferent widths and heights to produce a patterned wall having the appearance and bonding effectiveness of broken ashler masonry.
5. In a building wall, a series of uniformly constructed units; each unit comprising a plurality of blocks each of which is adjacent to others of different width and height, said with joints in the adjacent dumb-bell units Y joints of each cruciform unit being disposed asymmetrically of the horizontal axis of the unit and alternate cruciform units being inj verted whereby the uniform contour and structure of duplicate units is rendered unnoticeable and a wall is produced havingthe appearance and bonding effectiveness of broken ashler construction.
In testimony whereof we hereunto affix our signatures this 27th day of April, 1929.
, JOHN I-I. ALLES.
blocks collectively providing the unit with a generally cruciform contour disposed symmetrically about a vertical axis; and other units of dumb-bell-like contour'betweeii adjacent cruciform units, the blocks of said units cooperating to produce a broken asliler appearance and bonding effect although the assembled arrangement of blocks in each unit is repeated lengthwise of the wall.
6. A building wall of preformed artificial stone blocks of a limited number of sizes as-V sembled in a series of uniformly constructed units of cruciform contour, each comprising a group of blocks each blocli being adjacent ee to other blocks differing therefrom in widths and heights, and units of blocks intermediate said cruciform units, each of said intermediate units being of dunib-bell-like contour; some horizontal joints between the blocks of a cruciform unit being continuous
