BUILDING BLOCK Filed Feb. 5, 1939 2 Sheets-Sheet 2 Invenio' .MZZe-SlfieemW A iiorneyl Patented Oct. 3, 1939 uNiTEo sr TENT OFFICE 3v Claims.

My invention relates to improvements in building blocks for constructing walls.

\ The primary object of the invention is to provide inexpensive, durable, moulded blocks adapted for the building of walls and the making of corners with or without the use of mortar or cement and whereby a wall structure may be built up with a heat and cold insulating air space throughout the same.

Another object is to provide building blocks of the character and for the purpose above indicated and adapted for building walls with a space throughout the same which may be easily packed with insulation material.

To the accomplishment of the foregoing, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawings, set forth in detail in the succeeding description and defined in the claims appended hereto.

In said drawings:

Figure 1 is a fragmentary view in perspective of a portion of a wall built up of buliding blocks constructed in accordance with my invention.

Figure 2 is a view in top plan of one of the side wall blocks.

Figure 3 is a view in bottom plan.

Figure 4 is a view in end elevation.

Figure 5 is a view in top plan of one of the corner blocks.

Figure 6 is a View in side elevation of the corner block looking at the inner side thereof, and

Figure '7 is a view in bottom plan of said corner block.

Referring to the drawings by numerals, the blocks of my invention include side wall blocks I and corner blocks 2 adapted to be laid end to end in layers and which will now be described in detail.

The side wall blocks I are substantially rectangular, hollow structures open at the top and end thereof and including a bottom 3 and side walls 4, the latter being rabbeted, or undercut, along the side edges thereof, as at 5, to provide a reduced bottom key part 6 fitting into the top of a preceding block. The side walls 4 are rabbeted along the upper edges thereof, as at 1, to provide internal shoulders 8 extending along said side walls for seating said key part 6 whereby the upper block fits flush on top of the preceding or lower block. One end of each block I is rabbeted around the bottom" 3 and side walls i thereof, as at 9, to provide a key extension Ill around said end, and at the opposite end of said block the side walls 4 are rabbetedinternally,

as at II, whereby when the blocks I are laid end I to end the extension IQ of one fits into the rabbeted end II of the other and said blocks are thus keyed together end to end. The side Wall blocks I are laid in staggered relation in alternate layers or rows so that the key part 6 of the blocks of a higher row span the keyed together ends of the blocks I of a lower row and thus interlock with two lower blocks thereby additionally keying all three blocks together.

The corner blocks 2 are L shaped and open at their top and end, said corner blocks each including a bottom I2 and side walls I3. Each corner block 2 is also rabbeted, or undercut, along the side edges of its bottom, as at I4, to provide a reduced bottom key part I5 on said bottom fitting into the top of a lower corner and side Wall block, the side walls I3 of the corner blocks 2 being rabbeted along the upper side edges thereof, as at I6, to form internal shoulders H for the same purpose as shoulders 8 of side wall blocks I. Also one end of each corner block 2 is rabbeted, as at I8, around the bottom I2 and side walls I3 to provide a key extension I9 on said end fitting into the rabbeted end II of a side wall block I, and the other end of each corner block 2 is rabbeted internally, as at 20, to receive the key extension In of a side wall block I. As will be understood, the corner blocks 2 are made in reverse formation for laying in staggered relation with the side wall blocks I. Also each corner block 2 has a cross web 2| forming a continuation of one short side wall I3 of the block and an extension of the adjacent shoulder I? thereof. At suitable points, the corner blocks 2 may be scored transversely, as at 2!, to simulate a juncture of side wall blocks I and for a purpose which will be apparent.

As will now be seen, the blocks I and 2 of my invention provide in a wall structure built up thereof horizontal conduits, as at 22, extending from corner to corner and completely closed. These conduits 22 provide for insulating the wall both against heat and cold and also provide channels which may be filled, in the building of the Wall, with any suitable insulation material. Another advantage of the conduits 22 is that they may be used for housing electric wires if desired. The describe-d blocks are preferably formed of glass.

The foregoing will, it is believed, sufiice to impart a clear understanding of my invention, without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to such modifications as fall fairly within the scope of the subjoined claims.

What I claim is:

1. A building block of the type to be laid in superposed rows end to end, said block being open at the top and ends thereof and comprising a bottom and parallel side walls, the bottom being rabbeted along the side edges thereof to provide a reduced key part on said bottom for fitting between the side walls of a subjacent block, the side walls being internally rabbeted to provide shoulders extending along the upper edges thereof for seating the key part of a superposed block, said block having at one end thereof a key extension for fitting into the open end of another block, the other end of the block being internally rabbeted to receive a key extension of another block.

2. A building block of the type to be laid in superposed rows end to end, said block being open at the top and ends thereof and comprising a bottom and parallel side walls, the bottom being rabbeted along theside edges thereof to provide a reduced key part on said bottom for fitting between the side walls of a subjacent block, the

side walls being internally rabbeted to provide shoulders extending along the upper edges thereof for seating the key part of a superposed block, said block having at one end thereof a key extension for fitting into the open end of another block, the other end of the block being internally rabbeted to receive a key extension of another block, and said block being L-shaped for constructing corners.

3. A building block of the type to be laid in superposed rows end to end, said block being open at the top and ends thereof and comprising a bottom and parallel side walls, the bottom being rabbeted along the side edges thereof to provide a reduced key part on said bottom for fitting between the side wallsof a subjacent block, the side walls being internally rabbeted to provide shoulders extending along the upper edges thereof for'seating the key part of a superposed block, said block having at one end thereof a key-extension for fitting into the open end of another block, the other end of the block being constructed and arranged to receive a key extension of another block, 7
