Abstract
Abstract A U-shaped plate has locating notches in the ends of the legs providing surfaces that are received between the ridges forming the standard configuration of a concrete reinforcing bar. The plate is clamped against either a pair of rods to hold them in interengagement, or against one rod to secure an additional rod attached to the legs of the plate in parallelism to the clamped rod.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
In combination with at least one rod having regularly spaced ridges in planes inclined to the axis of said rod, a splicing device for securing an additional rod to said one rod in overlapping relationship, said device including U-bolt means gripping said one rod between and in engagement with one of said ridges, wherein the improvement comprises: a U-shaped plate member having a back and spaced legs at the opposite extremities of said back, respectively, said back having at least one aperture normally receiving said U-bolt means, and said legs having aligned tapered notches in the ends thereof, respectively, said legs being disposed to be received between said ridges at points of contact between said notches and said one rod and said legs being spaced apart sufficiently to allow said U-bolt means to accommodate the inclination and spacing of said ridges that lie between the planes of said legs.
Claim 2
Dependent Claim
149 words
In combination with at least one rod having regularly spaced ridges in planes inclined to the axis of said rod, a splicing device for securing an additional rod to said one rod in overlapping relationship, said device including U-bolt means gripping said one rod between and in engagement with one of said ridges, wherein the improvement comprises: a U-shaped plate member having a back and spaced legs at the opposite extremities of said back, respectively, said back having at least one aperture normally receiving said U-bolt means, and said legs having aligned tapered notches in the ends thereof, respectively, said legs being disposed to be received between said ridges at points of contact between said notches and said one rod and said legs being spaced apart sufficiently to allow said U-bolt means to accommodate the inclination and spacing of said ridges that lie between the planes of said legs.
Claim 3
Dependent Claim
27 words
A device as defined in combination in claim 1, wherein said legs have aligned apertures, respectively, on an axis parallel to the alignment axis of said notches.
Claim 4
Dependent Claim
61 words
A device as defined in combination in claim 1, wherein said additional rod is incorporated in said combination, and is provided with the ridge configuration of said one rod, and wherein said U-bolt means includes at least two U-bolts disposed in planes parallel to said ridges, and interposed in bearing contact between ridges on said one rod and additional rod, respectively.
Claim 5
Dependent Claim
133 words
In combination with at least one rod having regularly spaced ridges in planes inclined to the axis of said rod, a splicing device for securing an additional rod to said one rod in overlapping relationship, said device including U-bolt means adapted to grip said one rod between said ridges, wherein the improvement comprises: a U-shaped plate member having a back and spaced legs at the opposite extremities of said back, respectively, said back having at least one aperture normally receiving said U-bolt means, and said legs having aligned notches in the ends thereof, respectively, said legs being disposed to be received between said ridges at points of contact between said notches and said one rod, said legs additionally having aligned apertures, respectively, on an axis parallel to the alignment axis of said notches.
Claim 6
Dependent Claim
133 words
In combination with at least one rod having regularly spaced ridges in planes inclined to the axis of said rod, a splicing device for securing an additional rod to said one rod in overlapping relationship, said device including U-bolt means adapted to grip said one rod between said ridges, wherein the improvement comprises: a U-shaped plate member having a back and spaced legs at the opposite extremities of said back, respectively, said back having at least one aperture normally receiving said U-bolt means, and said legs having aligned notches in the ends thereof, respectively, said legs being disposed to be received between said ridges at points of contact between said notches and said one rod, said legs additionally having aligned apertures, respectively, on an axis parallel to the alignment axis of said notches.
Claim 7
Dependent Claim
22 words
A device as defined in combination in claim 4, wherein said aperture axis is disposed between the legs of said U-bolt means.
Claim 8
Dependent Claim
30 words
A device as defined in combination in claim 5, wherein said notches are V-shaped, and the axis of said apertures is disposed on the plane of symmetry of said notches.
