. WALL CONSTRUCTION.

Application med may 29,

To all w from it ma'jconic'em Be it known that I, DENNIS JOHN FLYNN, a citizen of the United States, and a resident of New Brunswick, in the county of Middlesex and State'of'Now Jersey, have invented a new and Improved Wall Construction, of which the following is a full, clear, and exact description.

The invention relates to wall construction formed ofouter and inner wall sections with an air space between them, as shown and described, for instance, in the Letters Patent of the United States, No. 1,329,893, granted to me on February 3, 1920.

The object of the present invention is to provide a new and improvedwall construction formed'of hollow building blocks arranged to compensate for any irregularities in the blocks when building the inner and outer wall sections and tying the same together.

Another object is to provide a building block capable for use as'awhole in walls, partitions, party walls, and the like, or to be split by the mason'for use in forming two opposite building blocks in the spaced outer and inner wall sections.

Another object is to increase thestability of the outer .and inner wall sections by firmly uniting the key or tying blocks by mortar with the opposite blocks of the outer and inner wall sections.

Another object is to 'make provision for the proper admission of stucco at the outer faces of the wall, plaster at the inner face and mortar between adjacent blocks in each course of the outer and inner wall sections.

With these and other objects in view, the invention consists of certain novel features of construction as hereinafter shown and described and particularly pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan View of the wall construction;

Figure 2 is a cross section of the same on the line 4-4 of Figure 1;

Figure 3 is a reduced face view. of the same; and a Figure 4 is a plan View of a modified form of the building blocks.

isformed of an inner wall section 10 and an outer wall section 11, 'the sections being spaced apart to provide a dead air space 12 between the said sections, as plainly shown in Figures 1 and 2. Each of the wall seclow blocks 15 and 16, and alike in construction and have on their inner sides vertically disposed dovetail grooves 24, 25, preferably located at the vertical median lines of the said inner sides. Each of the blocks 15 and 16 is preferably provided with three vertically disposed openings, but for thicker blocks, as shown in Figure 4, another row of openings isadded, but I do not limit myself to the number of such openings in any one of the'blocks, but each is preferably made hollow. The two blocks 15 and 16 are setopposite each other in the inner and outer wall sections 10 and 11. It is understood that building blocks made of plastic material are liable to warp in the process of manufacture, and the texture of the building blocks also varies according to the different batches of semi-plastic material from which such blocks are made The oppositely disposed blocks 15 and 16 of the inner and outer wall sections 10'and 11 are connected with each other by a key or tying block 30 made of a plastic material and having its sides provided with dovetail tongues 31, 32 loosely engaging the corresponding dovetail grooves 24, 25 of the opposite blocks 15 and 16. The dovetail tongues'Sland 32 have their corners 33 tions 10 and 11 is formed of courses of holrounded off and each dovetail tongue 31 and 32 is provided at the outer side with a depression or recess 34. In building the wall layers of mortar-35 are placed between the courses and a portion of this mortar passes into the top and bottom ortions of the dovetail grooves 24, 25 to fi l the spaces between the inner walls of the said grooves 24, 25 and the outer surfaces of the dovetail tongues 31 and 32 to securely fasten the key or tying blocks 30 in place and to firmly bind the blocks 15 and 16 witheach other, at the same time holding these blocks the de sired distance spaced apart to form the dead air space 12. v Each key or tying block 30 is preferably made hollow, as plainly indicated in Figure 1, to combine lightness with strength and to permit convenient handling of the key or tying blocks when building the wall.

By the arrangement described the inner I and outer wall sections can be readily set up and the opposite building blocks 15 and 16 can be readily connected with each other by the use of the key or tying blocks 30, owing to their construction as described, can be readily engaged by their dovetail tongues 31, 32 w1th the larger dovetail grooves 24, 25, as above set forth and shown in Figure 1. A wall built in the manner described is exceedingly strong and durable. In practice, the building blocks in one course break joint, with the building blocks in the opposite course and at the same timev the grooves 24, 25 of the building blocks in one course are out of register with the grooves 24, 25 of the building blocks in the preceding course (seeFigures 1 and 3), and hence a key or tying block in the registering grooves 24, 25 of the building blocks 15, 16 in one course rests at its lower end on the top of the building blocks immediately below the next course, and hence such key or tying block 30 cannot slide downward out of engagement with its grooves 24, 25 in the pair of building blocks 15, 16 tied together by such key or tying block 30.

7 The outer faces of the building blocks 15, 16 are provided with vertically disposed grooves 50, 51, preferably of dovetail shape, and similar grooves 52, 53 and 54, 55 are arranged at the sides of the blocks 15, 16. The grooves 50 are adapted to receive plaster while the grooves 51 receive'stucco, and the registering grooves 52, 53, 54, 55 of adjacent blocks 15, 15 and 16, 16 in the inner and outer wall sections 10 and 11 are adapted to receive a portion of the mortar 35 to firmly unite the adjacent blocks with each other;

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A wall construction, comprlsing inner and outer wall sections spaced apart to pro vide a dead air space between them, each section being formed of hollow building tongue and groove surfaces.

at its sides in dovetail tongues extending in a pa1r of registering dovetail grooves in a pair of opposite building blocks, the outer side of each dovetail tongue being provided with a recess, the outer surface of each dovetail tongue being spaced from the inner surface of a corresponding dovetail groove and a plastic binding material filling the space between the said tongue and groove surfaces.

2. A wall construction, comprising inner and outer wall sections spaced apart to provide a dead air space between them,'each section being formed of hollow building blocks each providedat the center of its inner face with a vertically disposed dovetail groove, of which the dovetail grooves of the blocks of the inner wall section are in register with the dovetail grooves in the blocks of the outer wall section, and hollow tying blocks, one for each pair of oppositely disposed building blocks of the inner and outer wall sections, each tying block terminating at its sides in dovetail tongues extending in a pair of registering dovetail grooves in a 7 pair of opposite building blocks, the corners of each dovetail tongue being roundedroif and the outer side of each dovetail tongue being provided with a recess, the outer surface ofv each dovetail tongue being spaced from the inner surface of a'corresponding dovetail groove, and. a plastic binding material filling the space between the said DENNIS JOHNIFLVYNN.
