Poured floor level indicator

Claim 1

A device for indicating the level of poured floors cmprising: an indicator member receipt shaft having defined therein an indicator member receipt shaft aperture; receipt shaft engagement means located on said indicator receipt shaft within said indicator member receipt shaft aperture; an indicator member having a top and having imprinted thereon at least one scale; indicator member engagement means located upon said indicator member and adapted to be engaged with said receipt shaft engagement means when said indicator member is inserted into said indicator member receipt shaft aperture a predetermined distance, said indicator member engagement means being further adapted so as not to protrude beyond the indicator member receipt shaft, said indicator member's top adapted to be at the level of the floor to be poured after said indicator member is inserted into said indicator member receipt shaft said predetermined distance; said indicator member engagement means further including: a key slot defined within said indicator member receipt shaft; a key section located on said indicator member adapted to mate with said key slot; a plurality of first engagement projections equidistant from one another arranged in a column along the inside of the indicator member receipt shaft within the indicator member receipt shaft aperture; and at least one second engagement projection located on said indicator member adapted to mate with said first engagement projections when said indicator member is inserted into said indicator member receipt shaft a predetermined distance and is rotated.

Claim 2

A device for indicating the level of poured floors cmprising: an indicator member receipt shaft having defined therein an indicator member receipt shaft aperture; receipt shaft engagement means located on said indicator receipt shaft within said indicator member receipt shaft aperture; an indicator member having a top and having imprinted thereon at least one scale; indicator member engagement means located upon said indicator member and adapted to be engaged with said receipt shaft engagement means when said indicator member is inserted into said indicator member receipt shaft aperture a predetermined distance, said indicator member engagement means being further adapted so as not to protrude beyond the indicator member receipt shaft, said indicator member's top adapted to be at the level of the floor to be poured after said indicator member is inserted into said indicator member receipt shaft said predetermined distance; said indicator member engagement means further including: a key slot defined within said indicator member receipt shaft; a key section located on said indicator member adapted to mate with said key slot; a plurality of first engagement projections equidistant from one another arranged in a column along the inside of the indicator member receipt shaft within the indicator member receipt shaft aperture; and at least one second engagement projection located on said indicator member adapted to mate with said first engagement projections when said indicator member is inserted into said indicator member receipt shaft a predetermined distance and is rotated.

Claim 6

A device for indicating the level of poured floors comprising: an indicator member receipt shaft having defined therein an indicator member receipt shaft aperture; receipt shaft engagement means located on said indicator receipt shaft within said indicator member receipt shaft aperture; an indicator member having imprinted thereon at least one scale; and indicator member engagement means located upon said indicator member and adapted to be engaged with said receipt shaft engagement means when said indicator member is inserted into said indicator member receipt shaft aperture a predetermined distance, further including means for determining said predetermined distance for insertion of said indicator member into said indicator member receipt shaft aperture wherein said means for determining said predetermined distance comprises an indicator setting post having an adjustable slide member thereon, said slide member being imprinted with a like scale to that imprinted upon said indicator member and adjusted in a position upon said indicator setting post whereby when said indicator setting post is located upon the bench mark of the floor to be poured and said slide member is viewed through a transit in a set position, said scale reads zero and upon placement of said indicator setting post at the site of said indicator member receipt shaft, the depth of insertion of the indicator member can be read off said slide member by viewing said slide member through said transit.

Claim 7

A device for indicating the level of poured floors comprising: an indicator member receipt shaft having defined therein an indicator member receipt shaft aperture; receipt shaft engagement means located on said indicator receipt shaft within said indicator member receipt shaft aperture; an indicator member having imprinted thereon at least one scale; and indicator member engagement means located upon said indicator member and adapted to be engaged with said receipt shaft engagement means when said indicator member is inserted into said indicator member receipt shaft aperture a predetermined distance, further including means for determining said predetermined distance for insertion of said indicator member into said indicator member receipt shaft aperture wherein said means for determining said predetermined distance comprises an indicator setting post having an adjustable slide member thereon, said slide member being imprinted with a like scale to that imprinted upon said indicator member and adjusted in a position upon said indicator setting post whereby when said indicator setting post is located upon the bench mark of the floor to be poured and said slide member is viewed through a transit in a set position, said scale reads zero and upon placement of said indicator setting post at the site of said indicator member receipt shaft, the depth of insertion of the indicator member can be read off said slide member by viewing said slide member through said transit.
