HOLLOW-WALL To all whom it may concern:

Be it known that I, FREDERICK HEATH, a citizen of the United States, and a resident ofTacoma, in the county of Pierce and State of Washington, have invented a certain new and useful Improvement in Hollow-Wall Construction, of which the following is a specification.

My invention relates to improvements in hollow wall constructions, and it consists in the arrangements herein described and claimed.

An object of the invention is to provide a wall 1 construction in which hollow blocks may be laid horizontally without exposing the voids in the blocks. To this end, I make use of mitered blocks at the corners which alternate with blocks disposed Vertically, the construction being such that the voids are not only hidden, but the courses are locked together. V

A further object of my invention is to provide a mitered hollow block.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

y invention is illustrated in-the accompanying drawing forming a part of this application in which:

Figure 1 is a perspective view showing a twelve inch wall constructed according to my invention, the upper courses being separated to illustrate the construction;

Fig. 2 is an enlarged detail horizontal sectional view through one of the courses hav-.

ing the mitered blocks;

Fig. 3 is a perspective view of a pier or column, and

Fig. 4 is a sectional view through a portion of a window jamb construction.

In carrying out my invention, I make use of mitered hollow blocks. These blocks may have one or more voids. In Fig. 1 I have shown a block A, having three voids, but it will be understood that the invention is not confined to a block having any particular number of voids.

As will be seen from Fig. 2, the block B is out along the line I), while the companion block C is out along the line 0. In Fig. 4 the block D is cut along the line d, while the block E is out along the line 6. The construction described permits the making of a CONSTRUCTION.

corner by fitting the blocks together in such manner as to hide the voids.

Referring now particularly to Fig. 1, I have shown therein a wall made up of an outer row of relatively wide blocks, such as eight inch blocks, and an inner row of relatively narrow blocks, such as four inch blocks. This wall is composed of blocks F which are of the ordinary rectangular shape. The blocks A are also rectangular, and are similar in form to the blocks F and are laid vertically. Above the blocks A are the mitered blocks B and C, these blocks being so arranged that they cover the voids of the blocks A while fitting together in a manner to conceal their own voids. Above the blocks B and C is another corner block A, while above the second block A are other blocks B and O.

The construction described permits the laying of the majority of the blocks horizontally. In the ordinary manner of completing piers ,or walls, where the blocks are laid vertically, the mortar will fall down into the voids, filling up the voids, and at the same time weakening the construction,

since relatively little mortar will remain on the narrow edges. My form of construction provides a broad base for the mortar and it also tends to lock the various courses, thereby providing a stable as well as a sightly construction.

In Fig. 3 I have shown the manner of constructing a pier or column. In this figure, as in Fig. 1, the courses have mitered blocks B and C alining with vertically arranged corner blocks A. The construction is especially desirable in columns and piers, since these have to bear heavy loads and are far more stable when the blocks'are laid horizontally, for the reasons stated above.

In Fig. 4 I have shown a means for constructing a window jamb. In this figure the blocks F are ordinary rectangular blocks. The block D is similar to the block B of the wall shown in Fig. 1. The block E, however, is mitered, so that when assembled with the block D it will complete the block and be of any desired thickness, without departing from the spirit of the invention.

The material of which the block is composed forms no essential part of the invencourse, may be molded and then allowed to set in molds which form the mitered blocks.

It will be understood also that while I have shown the blocks as mitered at an angle of forty-five degrees, they may be mitered at dilterent angles, or the blocks may be of different lengths than those shown in the drawings, without departing from the invention.

1 claim 1. A hollow wall construction comprising a series of hollow blocks arranged in courses, the majority of said hollow blocks being laid horizontally, certain of the blocks being arranged in vertical position to form corners of certain courses, and mitered blocks disposed atthe corners of the remaining courses adjacent to the vertically disposed blocks. 7

2. In a hollow wall construction, a plurality of courses of hollow blocks, the maj ority of said hollow blocks beinglaid horizontally, a series of hollow blocks disposed at the corner of the wall in vertical position, a pair of mitered blocks fitting together along their mitered edges, said mitered blocks being disposed between the adjacent vertical blocks. 7 j I I 3. A hollowwall construction comprising a series of courses of horizontally laid hollow blocks, the blocks of certain courses having a 'corner'block consisting of one of the horizontal blocks laid vertically, other adjacent courses consisting of hollow blocks laid horizontally, the corners of saidlast named courses comprising a pair of mitered hollow blocks placed together along their mitered edges and arranged to engage the ends of the vertically disposed blocks in adjacent courses, so as to cover the voids in the vertically disposed blocks.

l. A hollow wall constructlon consisting of a pluralityof courses of horizontally laid hollow blocks, the voids of said blocks running in a horizontal direction, the blocks of cover the voids in the vertically disposed,

blocks. a 7
