BUILDING-BLOCK. l

Specification of Letters Patent.

Patented Der.. l?, 1912.

Application filed November 17, 17.910. Serial No. 592,824.

To all whoml'it may concern:

Be it' known that I, FERDINAND Bonoli- An'rz, a citizen of the United States, and resident of the borough of- Manhattan, city,` "county, and State of New York, have in vented certain new and useful Improvements is a specication.

My invention relates to blocks sueltas are used in buildings, particularly for the construction of floors and ceilings, and has for in Building-Blocks, of which tlie following vits object to 'provide a novel sectional block which will be readily manufactured, light in weight, fire-proof, and a good heat-insulator.

Various forms of my invention are illustrated in the accompanying drawings, in which- Figure l is a plan `View showing a port-ion of a floor made with square blocks embodying my invention; Fig. 2 is a perspective View of two sections forming a block such as represented in F ig. l, said sections being shown separated; Fig. 3 is a. perspective view, similar to Fig. 2, showing another -way of constructing square blocks according to my invention; and Fig. lis a plan view of a hexagonal block embodying my invention.

In veach vof the forms shown, the block co'mln'ises two like hollow sections each having parallel main surfaces, adapted to form the top and bottom surfaces of the bloclr respectively when 'the blocks are used to construct a, floor or ceiling. Each block is of polygonal shape, and the open meeting surfaces of companion sections are disposed digunetrically with respect to they polygonal -outline of the block, and preferably, as

shown, such meeting surfaces are .in planes perpendicular to thefparallel surfaces above mentioned.

Turning more specially to the blocks illus- .ti-ated by Figs. l and 2, I have shown each 'block section shaped substantially as a. hollow triangular' prism havingy a horizontal top surface A, abottom surface A. parallel thereto, converging vertical side walls A2, and -an open vertical surface A3 which eX- tends between the ends of the side walls and which 'I term a meeting surface since it is adapted to fit against the corresponding surface of a companion section to form a block squareoutline, as shown in Fig. 1L Each bleclrseetion is hollow and open at the meeting surface A3 but closed otherwise. Tfl-Then two companion sections are fitted together, they form a hollow block the walls of `which are closed entirely. -The meeting surfaces A3 are vertical, that y is, perpendicular to the parallel surfaces A, A', and in the assembled block the meeting surfaces (indicated by the lines a in Fig. l) are disposed diametrically with respect to the polygonal (square) outline of the block.

prefer to make the block sections with flanges At'extending at the bottom beyond the side walls A2 and adapted to abut against the corresponding flanges of adj acont blocks'.v as shown in Fig. l, thus leaving spaces between the side walls A2 of adjoining bloclrs, to receive the customary supporting rods (two of which are indicated at D) and the cement i'illing not shown) in which they are i embedded as usual. Of course the improved 4blocks may be 4applied in 'other ways, and l have used the terms top and bottom, horizontal and vertical, only for the salte of convenience of description, since it will he obvious that the blocks might be used in other positions.

The block illustrated in Fig. l lillois from that shown in l and 2 only by the fact that 'the diamotral meeting surfaces il are parallel to one set of sido walls BZ, instead 'of being arranged diagonally as in llig .l andi?. The outline of each bloeit section is therefore rectangulaiinstead of tri oular.

Fig. 3 represents a hexagonal bloei embodying my invention. lllachseciion i .p-A onoidal in outline. with the open meeting surfaces (indicated at c) ari :geil in a diagonal. It will be understood that in other respects the forms shown in 3 and 4 agree with the one shown in Figs. l and 2, hence further description is deemed unnecessary, corresponding parts being designated by reference letters bearing like indices.

The block sections herein described are made by molding or otherwise `from cement or other suitable material.

l claim as my invention:

A completely closed hollow sectional po-A lygonal building block having a single inner chamber occupying the whole interior thereof and composed of two similar hollow half sections comprising respectively integral top,

bottom and angled side walls, said sections opening into each other diarnetricalyfrom specification in the presence of two subscrih- Y end to end thereof and being provided reing Witnesses. spectively along their said angled side Walls with integral angled outward spacing flanges FERDINAND.
