Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
A removable stand-off arrangement for masonry levels having I beam construction comprising: a rectangular central member having a top aperture and a bottom longitudinal slot, said central member having in-turned end sections defining said longitudinal slot, an integral subassembly including a pair of disc-shaped end sections joined by a cylindrical spacer section, said subassembly being partially situated inside of said central member with said cylindrical spacer section within said top aperture and one of said disc-shaped end sections confined within said central member, and a tensioning spring wrapped about said spacer section and being in touching engagement with a top surface of said last-mentioned disc-shaped end section and an interior surface of said central member when under tension.
Claim 2
Dependent Claim
118 words
A removable stand-off arrangement for masonry levels having I beam construction comprising: a rectangular central member having a top aperture and a bottom longitudinal slot, said central member having in-turned end sections defining said longitudinal slot, an integral subassembly including a pair of disc-shaped end sections joined by a cylindrical spacer section, said subassembly being partially situated inside of said central member with said cylindrical spacer section within said top aperture and one of said disc-shaped end sections confined within said central member, and a tensioning spring wrapped about said spacer section and being in touching engagement with a top surface of said last-mentioned disc-shaped end section and an interior surface of said central member when under tension.
Claim 3
Dependent Claim
48 words
The invention recited in claim 1 wherein said subassembly parts consisting of said end sections and said spacer section may be disassembled into three separate parts, and reassembled within said central member and secured therein as an integral subassembly through axial aligned apertures in each of said parts.
Claim 4
Dependent Claim
107 words
A portable stand-off arrangement for levels comprising: a central member being substantially rectangular in cross section and having a slotted opening running longitudinally on one of its sides and a centrally situated aperture in a side opposite said slot; a cylindrical member inserted in said aperture and having a longitudinal boring therethrough; top and bottom disc members mounted on said cylindrical member and affixed thereto by a threaded insert which engages axially aligned borings in said disc member; and a spring installed on said cylindrical member and held in place between said bottom disc member and the internal surface of said opposite side of said central member.
Claim 5
Dependent Claim
107 words
A portable stand-off arrangement for levels comprising: a central member being substantially rectangular in cross section and having a slotted opening running longitudinally on one of its sides and a centrally situated aperture in a side opposite said slot; a cylindrical member inserted in said aperture and having a longitudinal boring therethrough; top and bottom disc members mounted on said cylindrical member and affixed thereto by a threaded insert which engages axially aligned borings in said disc member; and a spring installed on said cylindrical member and held in place between said bottom disc member and the internal surface of said opposite side of said central member.
Claim 6
Dependent Claim
22 words
The invention recited in claim 3 in combination with level having an I beam construction adapted to mate with said central member.
