Application filed Deoember28, 1923. Serial no. 683,252;
Another object of the invention is the provision ofa concrete building block with an air passage extendin the block and through the meeting ends of the block, so the blocks will be provided with air space under all blocks in the same vertical plane and the airspace ofvone horizontal row'of blocks will be in communication with the air space of the horizontal rows parallel therewith, through passages formed in the interlocking ends of companion blocks;
Other objects will appear fromthe following specification of the drawings which il lustrate the practical embodiment of the invention. In thedrawings, V
Fig. 1 is a perspective View of a single block. I I i i Fig. 2 is a bottom plan View thereof.
Fig. 3 is an end view two blocks in superimposed relation.
Fig. 4 is a plan view of two interlocked blocks.
Fig. 5 is a side elevation of a portion of a wall.
Referring to' the accompanying drawings 5 designates one of the" building blocks,
which is composed of cement, concrete. or s preferably formed by cold moulding. The block 5 is formed with a longitudinal air passage or channel 6 in its base, which is located be tween the legs 7 and 8 which extend from" one end of the block to the other end.
One end of the block 5 is formed witha recess 9'and the sidewalls 10 and 11 of this recess are disposed on outwardly diverging planes. The other end of the block is formed with alocking-lug 12, the depth of which is considerably less than the depth of the recess 9, and the sides of this lug 12 converge toward their end face ofthe lug. The
lug of one block is inserted in the recessed end of the adjacent block of the same horizontal row in a wall construction, and the 7 meeting faces of the opposing ends of the blocks are cemented by means of cement or the like 13, as indicated in Fig. 4. It will be seen from an examination of this figure that the base of the recess 9 is not filled with so that its g longitudinally of that a wall constructed with the cement, so that a normally open'air passage 14L is thus formed between the end face i of the locking lug and the base of the recess.
hen a series of blocks are arranged in interlocked relation the air passages 14; will be in normal conimunic passages 6 of the blocks of the same horizontal row, and theair passages 6 of one horizontal row will" be in normal communi cation with the similar air passages ofeach I other horizontal row of a building. wall.
The cement or mortar which unites each block to its neighbor block of one horizontal row to the adjacent horizontal row is dis ation with the air posed on the head face of the blocks of one I horizontal row so that an excess amount of cement may be worked against the inner i faces of the legs 7 and 8 to provide widened sealing joints-or shoulders for said legs,
that when a horizontal row of blocks has been laid a continuous longitudinal arch is formed, The'top face offeach block is closed, between the base face of the recess and the end face of the locking lug, so that the arch thus composed will have the greatest supporting strength.
Owing to the sloping side faces and the U-shaped body. construction of the. entire block it can 'bemoulded with greater which willinsure" against slippage and leak I Each block forms a longitudinal arch so economy of time and labor and without dans ger of producing clogged passages or defective faces. In forming the block a greater density can be obtained, by reason of the fact that pressure can be applied to the concrete from one side of the block.
Owing to the construction of the recess and. terminalblock a finger space will be "provided at the meeting ends of a series of blocks which will enable the Workman to have fullcontrol of the block while placing it in position or adjusting it after it has been placed in building row formation- Havingdescribed my invention I claim 1 1.; A concrete block wall construction comprising a series of'concrete blocks arranged end to end in horizontal superimposed rows,
each block having a relativelydeep longitudinal channel extendingfrom one end to the other end and providing a roof POTUOII thereof of considerable less thickness than c the vertical thickness of the block, one end ofeach block having a recess wide enough to receive the fingers of a human hand,sa1d
recess having outwardly diverging sides, the adjacent block end having a tenon or corresponding shape to the recess and disposed in said recess, said tenon being of less depth than the recess to compose a normally open air passage with capacity suiiicient to receive the fingers of a human hand, the under face of the top all portion of the channel being graspable by the fingers of a hand inserted in said recess, each of said blocks having one such tenon on the opposite end to said recess.
2. A concrete block having a longitudinal channel providing an overlying roof and having a recess on one end and a tenon on the other end, the recess being deep enough to receive the fingers of the hand of aworker without cramping and the tenon being of less depth than the recess, the tenon of one block entering the recess of an adjacent block in wall forming linear alignment, the distance between the upper face of the block and the underface thereof immediately over the channel being less than the length of human fingers to permit the fingers of a hand inserted in said recess or positioned around said tenon to fold under the channel roof.
