To all whom 'it may concern.: 4

Be 1t 'known that I, Jenn' donne, a citizen of the United States, and i dent el? it and useful In'iproveinonts in .ll ,infox'ccd- Concrete Floor Construction, ol. which the followingis n specification, containing :1 full, clear, and exact description, reference be 'had to the a'ccompanyingdrawings, 'forming a art hereof.

'i' y invention relates to n reinforced concrete floor construction, the ohiiA of any invention being-st: to materially inroepen the cost 'of reinforced concrete flooring; fnd

to greatly increase the cnsile srrcngth or' 'the i y span or slab of flooring` between the door beams; 3rd: todo a'way with iihe r'iwng of clnclers, or the like, which 1s nsua ily empl' 1n4 the construction of concrete floor:

floor sleepers are arranfrcd .in die upper poi tion of the concrete lloorin` to 'icrfe tl )urpose of guides for thc top su .ce of ooring, and to provide means for eef. 1 the Wooden ilooring to the concrei e minstreel tion.

To the above purposes, ray invention ce sists in certain novel .ienturee of consirucion and arrangement of parte, 'which will be lhereinaf'be'r more full eet forth, pointed on in the claims, and il ustrnled in 'the .acemn panying drawings, in which Figure 1- is a cross section miren hrough a portion of a Span or Slob of concrete licor- .ing constructed in accordance with injf invention, and showing a part o5 the renderne :nent without the surrounding body or' con crete; Fig. 2 is a Section halfen egiii'noninnitel on the line 2%2 of Fig. l; Fi is n perM s ecti-Ve View of a stanchion or reinio or sleeper support l make use of in c ing out my'iniention; Fig. fl is a cra tion of the reinforcement need for .mining one of the beanie which supports izhc floor construction; Fig. 5 is :i vcriical eretico. taken on the line 5-5 oi' Vig, l.
