In the'drawings, wherein for the purpose of
a vertical locking recess28, arranged adjacent to,
and upon one side of a. vertical air circulating
opening 29. The corner block is provided in its
end ‘wall, 3|] with. a vertical locking recess 3!,
passing through the main recess 25 and upon its
35 illustration is shown a preferred embodiment of '
my invention, the numerals II), II and l2, desig- ‘
inneriside and adjacent to its opposite end wall
nate side walls, with the side walls Ill and I2
disposed at a right'angle to the side wall ll.
Each side wall comprises side blocks l3, see
40 more particularly Figure 6. Each side block has
throughthemrainr recess 25. e The corner block
32, with a vertical locking recess 33, also passing '
24 is provided in its bottom with an air circulat
ing groove 34, which extends longitudinally and
transversely of, the block and leads into the re
a main horizontal recess or passage l4 formed
therein, the walls i5 and it of which are at a
cesses 3| and 33 and also into the air circulating
right angle. The vertical wall It is provided with
a vertical locking recess ll, equi-distantly spaced
‘The corner block‘ in the next upper layer is
designated by the numeral 35 and is provided
45 from its opposite ends. The vertical locking re
cess H has one end open while its opposite end is
with a main recess 36, forming a reduced portion
closed by a wall L8. The numeral I9 designates a
vertical air circulating passage which is arranged
adjacent to the end wall I8 of the vertical locking
50 ‘recess I‘! and wholly upon the open side thereof.
This passage communicates with a horizontal air
circulating groove 19a, formed in the edge of the
blocks, at their central longitudinal axes. Each ,
block l3 has end walls 20, provided with vertical
55 , locking recesses 2i , opened at their opposite ends,
passage 29.

31, for insertion within the recess 25 of the corner
block and the recess M of thev adjacent side block.
This upper corner block is provided with a ver
tical intermediate locking recess 38, having its
lower end open and its top closed by an end wall
39, and also has a vertical air circulating passage
40, arranged adjacent to the recess 38 and upon
one side thereof. The air circulating passage 40
leads into an air circulating groove M formed
upon the upper face of the corner block 35; This
2
2,114,774
corner block is provided upon one vertical end
wall 42 with a vertical locking recess 43, passing
through the main recess 36 and communicating
with the air circulating groove 4|. Near its op
posite end wall 44, the block 35 is provided in its
side with a vertical locking recess 45 which also
intersects the transverse section of the main re
cess 36.
The numeral 46 designates I-locking-blocks,
which are vertically arranged in use and corre
spond in vertical dimensions to the side and cor
ner blocks. Each I-locking-block has side grooves
4'! and recesses 48 at their lower ends, and the
recesses 48 are in communication with the grooves
15 41, as shown.
In assembling the blocks in the ?rst layer to
produce the walls l0 and II, and corner at the
left, the side blocks l3 are arranged in end-to
end relation. The vertical locking recesses 2| of
20 one side block register with the vertical locking
recess 2| of the next side block. The corner
block 24 is next brought into position adjacent
to the side block |3 in wall l0, and its vertical
locking recess 3| will register with the locking
25 recess 2|.
The corner block 24 is also brought
into close proximity to the side block |3 of wall
II, and vertical locking recess 33 will register
with vertical locking recess 2|. The vertical I
locking-blocks 46 are now inserted into the as
30 sembled locking recesses 2| of the side blocks l3;
the assembled locking recesses 2| and 3| of the
side block in wall I0 and the corner block 24; and
in the assembled recesses 2| and 33 of the side
block in wall I | and the corner block 24.
In assembling the side blocks in the walls l0
and II in the next upper layer, the side blocks
are inverted and the side blocks in the upper layer
break joint with the side blocks in the lower layer.
The inverted side blocks |3 have their reduced
portions l4’ ?tting in the main recesses M of the
lower layer of blocks. The ends of the side blocks
in the upper layer terminate at the center line of
the recesses l‘! in the side blocks in the lower
layer and also at the center line of the recess 28
45 of the corner block 24. The recesses I‘! and 2|,
28 and 39 therefore provide vertical locking pas
sages for receiving the vertical I-locking-blocks
46. The recesses 48 in the I-locking-blocks are
in communication with the air circulating pas
sages l9 and with the air circulating grooves l9a.
When the corner block 35 is placed in position,
the reduced portion of its vertical locking recess
45 will register with recess 28 of the lower corner
block 24 and the vertical locking recess 2| of the
adjacent block |3 in wall l0, and these recesses
45, 2| and 28 will afford a vertical locking pas
sage for the vertical I-locking-block. The re
duced portion 31 of the corner block enters the
60 recess 25, and locking recess 39 coacts with look
ing recesses 33 and 2| of the side block in wall II
to afford a vertical locking passage for the vertical
I-locking-block 45. The vertical locking recess
H in the adjacent side block |3 of wall || coacts
65 with the vertical locking recess 43 in the corner
block 35 and the vertical locking recess 2| in the
adjacent inverted side block.
The construction of the wall I 2 is identical with
wall Ill and the corner blocks 24' and 35’ of walls
70 II and I2 with the corner blocks 24 and 35, ex
cept that they face in opposite directions.
The meeting surfaces of the blocks and the I
locking-blocks may have cement applied thereto,
to bond the blocks together, care being taken
75 that the cement does not enter the air circulating
passages or grooves to any considerable extent
and thereby retard ventilation.
In order that ventilation may be had between
the blocks from the interior and exterior of the
building, the side blocks in layers at different
elevations may have ventilating passages 41, lead—
ing into the ventilating passages I9, the hori
zontal ventilating passages 4'! extending in oppo
site directions, as shown in Figure 5.
It is to be understood that the form of my in
10
vention herewith shown and described is to be
taken as a preferred example of the same and
that various changes in the shape, size, and ar
rangement of parts may be resorted to, without
departing from the spirit of my invention or the 15
