Total Claims: 9
Claim 1
Independent Claim
174 words
In the manufacture of thin, reinforced cement shells, the combination comprising a mold having a forming surface complementary to the shell to be formed, a plurality of spacer members carried by said mold and projecting outwardly of said mold forming surface, means for holding a layer of reinforcement closely fitted to the contour of said mold surface but speed slightly therefrom by said spacer members an amount equivalent to the desired thickness of a layer of cementitious material to be applied under said reinforcement, and a plurality of elongated guides removably secured to saiD spacer members with said reinforcement interposed therebetween to retain the latter in position, said guides being disposed in spaced, substantially parallel relation for spanning by a smoothing device which is to be moved along and guided by outwardly facing portions of said guides to smooth the cementitious material, adjacent, outwardly facing portions of aforesaid adjoining guides being spaced from said reinforcement an amount equivalent to the desired thickness of a layer of cementitious material to be applied over said reinforcement.
Claim 2
Dependent Claim

In the manufacture of thin, reinforced cement shells, the combination comprising a mold having a forming surface complementary to the shell to be formed, a plurality of spacer members carried by said mold and projecting outwardly of said mold forming surface, means for holding a layer of reinforcement closely fitted to the contour of said mold surface but speed slightly therefrom by said spacer members an amount equivalent to the desired thickness of a layer of cementitious material to be applied under said reinforcement, and a plurality of elongated guides removably secured to saiD spacer members with said reinforcement interposed therebetween to retain the latter in position, said guides being disposed in spaced, substantially parallel relation for spanning by a smoothing device which is to be moved along and guided by outwardly facing portions of said guides to smooth the cementitious material, adjacent, outwardly facing portions of aforesaid adjoining guides being spaced from said reinforcement an amount equivalent to the desired thickness of a layer of cementitious material to be applied over said reinforcement.
Claim 3
Dependent Claim
20 words
The construction of claim 1 wherein said spacer members are elongated and wherein said guides extend along respective spacer members.
Claim 4
Dependent Claim
20 words
The construction of claim 2 wherein said guides are transversely flexible to conform to the contour of respective spacer members.
Claim 5
Dependent Claim
37 words
The construction of claim 1 wherein said spacer members are formed of material adapted to receive and retain nails driven thereinto, and wherein readily withdrawable nails are employed to removably secure said guides to said spacer members.
Claim 6
Dependent Claim

The construction of claim 1 wherein each guide aforesaid comprises a pair of angle members in spaced-apart, back-to-back relation, and wherein fastening members are disposed between the angles of said angle pairs and are removably anchored in respective spacer members to removably secure said guides to said spacer members.
Claim 8
Dependent Claim
42 words
The construction of claim 6 wherein hold down means are held in position by said fastening members, and wherein such means span the angles of a respective angle pair and are engaged therewith to interlock such angle members with respective fastening members.
Claim 9
Dependent Claim
57 words
The construction of claim 7 wherein said fastening members have a shank portion passing through respective hold down means and a headed portion overlying such hold down means, and wherein said means last mentioned have an intermediate portion extending between respective angles and lip portions extending transversely from said intermediate portion and engaged with respective angle members.
