SPECIFICATION formingpart of Letters Patent No. 701,165, dated May 27, 1902. Application iiled September 3, 1901. Serial No. 74,120. (No model.)

To all whom, it may concern.-

Be it known that I, ALPHONSE DE MAN, a citizen of the United States, and a resident of New York city, borough of Manhattan, in the county and State of New York,-have invented a new and Improved Building-Block, of which the following is a full, clear, and exact description.

The invention relates to fireproof flooring constructions, especially such as have I- beams as floor-supports; and the object of the invention is to provide a new and improved building-block reaching from one floor-supporting beam to the nextadjacent one and arranged to permit convenient handling and placing the blocks in position one alongside the other to form a sectional slab of great strength and durability and covering a space between the floor-beams and at the same time producing a flat ceiling and a straight top surface.

The invention consists of novel features and parts and combinations of the same, as .will be fully described hereinafter and then pointed out in the claims.

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

Figure l is a sectional side elevation of the improvement as applied, parts being in ele:

the other and extend between and are supported by adjacent floor-supporting or I beams B, asindicated in Figs. 1 and 2. The blocks are made of a suitable fireproof material which permits of molding the block to the desired shape when the material is in a plastic state, the said material being prefertension members. The general cross-section of a block A is that of an I-beam,which gives the most strength with the minimum of material.

As shown in the drawings, each block A consists, essentially, of a central web A, a top flange A a bottom flange A transverse partitions A at the ends of the Web A, and lugs A, extending outwardly from the partition in line with the web A. The top flange A extends somewhat beyond the partitions A -to pass under the top flanges of adjacent I-beams B, as plainly indicated in Fig. 1, and the lugs Aiproj ectsomewhat beyond the ends of the top flange A to reach close to the webs of the I-beams B. The partitions A are of the same'width as to the top and bottom flanges A and A and their outer faces extend in a vertical plane, touching the outer edges of the top and bottom flanges of the I-beams B. (See dotted lines, Fig. 2.) The edges of the top and bottom flanges A A and those of the partitions A are formed in such a manner that when the blocks are in position, as shown in Figs. 1 and 2, then the said edges ofadjacent blocks interlock to prevent vertical displacement of the blocks and form the latter'into a sectional slab of great strengthand durability,'the slab covering the space between the floor-beams. The lugs A rest with their lower edges on the upper surfaces of the bottom flanges of the I- beams B to support the block A on' the I- beams. In order to strengthen the top and bottom flanges of a long block, I provide the same on its web with transverse ribsA", ex"- tending to the top and bottom flanges A A as plainly shown in the drawings. The ends of the bottom flange A of each block terminate a short distance beyond the edge of the bottom flange of an I-b'eam B, and the said ends are preferably formed with bevels A for r'eceivin g filling-pieces 0. extending under the bottom-flangesof the Lbeams B. It is understood that the bottom flanges A are located somewhat belowthe bottom flanges of the I-beams B, while the upper surfaces of the top flanges A are below the top flanges of the .case of fire.

In large blocks the edges of the flanges are strengthened or reinforced by twisted wires D, extending lengthwise of the block and preventing the edges of the flanges from being broken, the bottom wires D also forming auxiliary tension members. In the upper surface of each top flange A are arranged" openings or recesses A containing wire screweyes E for the application of suitable hooks or other tools to allow the operator to conveniently move the blocks A in position one alongside the other, as illustrated in Fig. 2. The shanks of the screw-eyes extend vertically in the web A of the block, and thereby form strengthening-rods for the web.

When the blocks A are placed in position onealongside the other, the ends of the partitions A as well as the top and bottom flanges of adjacent blocks, interlock with each other, the joints being united byasuitable cement or mortar. It is evident that when the said blocks are in position and are fastened together, as described, the lugs A with the partitions A, form dead-air spaces with the I-beams B to protect the web A in It will also be seen that deadair spaces are formed between adjacent blocks A, so as to render the filling-blocks or floor between the I-beams B sound-proof. By securely fastening the blocks together in the manner set forth each sustains the adjacent one, all the blocks combining to form a sectional slab to properly sustain the load. A

floor constructed'in the manner described is ready for use as soon as the blocks A are in position, it being expressly understood that the blocks and filling-pieces O are completely dry when put in place tobe immediately ready for receiving any finishing work which may be required.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A floor construction, comprising floorsupporting beams, and floor-blocks arranged one alongside the other and extending between and supported from the adjacent floorsupporting beams, the said blocks being arranged to form dead-air spaces between the floor-supporting beams and the ends of adjacent blocks, the blocks having interlocking top and bottom flanges, as set forth.

2. A floor construction, comprising floorsupporting beams, and floor-blocks arranged one alongside the other and extending between and supported from the adjacent floorsupporting beams, thesaid blocks being arranged to form dead-air spaces between the floor-supporting beams and the ends of adjacent blocks, the said blocks being interlocked and fastened together at the interlocked joints by a suitablebinding substance, and the blocks forming dead-air spaces between adjacent blocks, as set forth.

a 5. A floor-block, of substantially an I-beam cross-section and having its top flange extending beyond the ends of the web, and lugs projecting from the ends of the web under the said top flange, as set forth.

6. A floor-block, of substantially an I-beam cross-section and having its top flange extending beyond the ends of the web, and lugs projecting from the ends of the web and a distance beyond the same, as set forth.

7. A floor-block, of substantially an I-beam cross-section and having its top flange extending beyond the ends of the web and the bottom flange terminating at the ends of the web, and lugs projecting from the ends of the Web in line therewith and beyond the ends of the said top flange, as set forth.

8. A floor-block, of substantially an I-bealn crosssection, and having transverse partitions at the ends of the web, the top flange,

extending beyond the partition, as set forth.

9. A floor-block, of substantially an I-beam oross-sectiomand having transverse partitions at the ends of the web, the top flange extending beyond the partition, the bottom flange terminating at the partition and having its ends beveled, as set forth.

A floor-block,of substantially an I-beam cross-section and having transverse partitions at the ends of the web, the top flange extending beyond the partition, lugs projecting outward from the partition in line with the web, and strengthening members at the top and bottom flanges of the block and extending longitudinally thereof, as set forth.

1?. A floor-block of substantially an I-beam cross-section, and having recesses in its top and supporting-eyes having twisted shanks embedded in the web of the block, the eyes extending in the said recesses, as set forth.

13. A floor-block,of substantially an I-beam cross-section and having transverse partitions at the ends of the Web, the edges of the partitions and those of the top and bottom flanges being arranged to interlock with the corresponding edges of adjacent blocks, as set forth.

14. A floor-block of substantially an I-beam cross-section and having lugs at the ends thereof above the bottom flange of the block, and a tension member extending in the bottom flange and the said lugs, as set forth.

15. A floor-block of substantially an I-beam cross-section, and having lugs at the ends thereof above the bottom flange of the block, and a tension member extending in the bottom flange and the said lugs at the middle of the flange and lugs, as set forth.
