Abstract
Abstract A method and mold for producing a concrete slotted floor for supporting animals. The mold includes a bottom part with a smooth top surface with lengthwise extending ridges formed thereon. The top part of the mold locks to the bottom part and includes a plurality of parallel slab separators seatable upon the ridges. The top part includes end walls and side walls defining an enclosure for receiving the poured concrete. The slab separators are spaced apart from the end walls allowing the concrete to extend completely around each separator to form integrally joined concrete slabs. Concrete is poured into the top part of the mold between each separator and across the ends of the separators. The mold is vibrated and the concrete is allowed to solidify. The top part of the mold is then lifted upwardly and the solidified concrete is removed and turned over in order that the smooth surface of the concrete contacting the bottom part of the mold faces upwardly. In the preferred embodiment, a wooden insert is removably mounted to the concrete slotted floor and positioned in an upwardly facing recess formed in the floor during the molding thereof.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A farrowing construction comprising: a plurality of concrete floors adapted to be placed over a pit to support animals, each of said floors having a plurality of concrete slats with first convex top crowns, said slats being spaced apart by slots to allow animal droppings to pass through said slots and with said slats having portions integrally joined to adjacent slats, said floors extending longitudinally across said pit and including upwardly facing sections recessed below said crowns; insert means removably mounted to said floors and positioned in said sections upon which animals may be located during nursing; first means located above said floors to limit movement of some of said animals atop said insert means; and second means cooperating with said insert means and said floors to limit relative movement therebetween, and wherein said floors have opposite ends with said upwardly facing sections located intermediate thereof, said slats extend longitudinally through said sections and have second convex top crowns positioned beneath said first convex top crowns spacing said insert means partially apart from said floors insuring air circulation therebetween.
Claim 2
Dependent Claim
179 words
A farrowing construction comprising: a plurality of concrete floors adapted to be placed over a pit to support animals, each of said floors having a plurality of concrete slats with first convex top crowns, said slats being spaced apart by slots to allow animal droppings to pass through said slots and with said slats having portions integrally joined to adjacent slats, said floors extending longitudinally across said pit and including upwardly facing sections recessed below said crowns; insert means removably mounted to said floors and positioned in said sections upon which animals may be located during nursing; first means located above said floors to limit movement of some of said animals atop said insert means; and second means cooperating with said insert means and said floors to limit relative movement therebetween, and wherein said floors have opposite ends with said upwardly facing sections located intermediate thereof, said slats extend longitudinally through said sections and have second convex top crowns positioned beneath said first convex top crowns spacing said insert means partially apart from said floors insuring air circulation therebetween.
Claim 3
Dependent Claim
155 words
A farrowing construction comprising: a plurality of concrete floors adapted to be placed over a pit to support animals, each of said floors having a plurality of concrete slats with first convex top crowns, said slats being spaced apart by slots to allow animal droppings to pass through said slots and with said slats having portions integrally joined to adjacent slats, said floors extending longitudinally across said pit and including upwardly facing sections recessed below said crowns; a plurality of wooden inserts removably mounted to said floors and positioned in said sections upon which animals may be located during nursing; first means located above said floors to limit movement of some of said animals atop said inserts; and second means cooperating with said inserts and said floors to limit relative movement therebetween, and wherein said second means includes rails mounted to and beneath said wooden inserts which are fittingly inserted into slots between said slats.
Claim 4
Dependent Claim
