Abstract
Abstract The invention contemplates a two-piece cable-clamp and bracket assembly especially suited for messenger-wire or the like suspension of two TV amplifier units, line extenders or the like from a single point along the suspension wire. The assembly is configured for naturally balanced, loosely retained initial engagement to and suspension from the wire. Loose retention is by way of a nut and bolt, and the parts interengage to assure correct mutual orientation at all times, such that all aspects of assembly to, adjustment along, and final clamping involve only one-handed operation. The final clamped engagement to the wire assures keyed anti-rotational suspension from the wire.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
226 words
A suspension-cable fitting for clamped assembly to a longitudinally extending messenger wire or the like cable of given-diameter, comprising a unitary stiff metal bracket of generally U-shape formed from strip material, said bracket having a base panel with a separate side panel depending integrally from each end of said base panel, said base panel being characterized by a central upwardly displaced transverse rib of concave sectional span and depth to nest and locate substantially half the cross-section of the messenger wire or the like, whereby said bracket is self-stabilizing when so placed on the wire or cable as to receive the wire or cable in the concavity of the rib, a localized portion of said base panel adjacent said rib being displaced at offset from the rest of said base panel and to substantially the extent of offset at said rib, said localized portion having a bolt-receiving aperture on a vertical axis of alignment offset from the elongation axis of said rib; and a channel-shaped clamp member of formed stiff sheet material having a base and upstanding walls which are spaced to receive the width of said base panel therebetween, said base having a bolt-receiving aperture, and a bolt through both apertures, each of said side walls having an upwardly open generally V-shaped recess on the transverse alignment of wire or cable nesting in said rib.
Claim 2
Dependent Claim
226 words
A suspension-cable fitting for clamped assembly to a longitudinally extending messenger wire or the like cable of given-diameter, comprising a unitary stiff metal bracket of generally U-shape formed from strip material, said bracket having a base panel with a separate side panel depending integrally from each end of said base panel, said base panel being characterized by a central upwardly displaced transverse rib of concave sectional span and depth to nest and locate substantially half the cross-section of the messenger wire or the like, whereby said bracket is self-stabilizing when so placed on the wire or cable as to receive the wire or cable in the concavity of the rib, a localized portion of said base panel adjacent said rib being displaced at offset from the rest of said base panel and to substantially the extent of offset at said rib, said localized portion having a bolt-receiving aperture on a vertical axis of alignment offset from the elongation axis of said rib; and a channel-shaped clamp member of formed stiff sheet material having a base and upstanding walls which are spaced to receive the width of said base panel therebetween, said base having a bolt-receiving aperture, and a bolt through both apertures, each of said side walls having an upwardly open generally V-shaped recess on the transverse alignment of wire or cable nesting in said rib.
Claim 3
Dependent Claim
50 words
The fitting of claim 1, in which said clamp member additionally includes an upstanding integral lug formation between said side walls and at offset from the bolt aperture of said clamp member, the latter offset being in the direction opposite to that of the traverse alignment of the V-shaped recesses.
Claim 4
Dependent Claim
23 words
The fitting of claim 2, in which the effective depth of said V-shaped recesses is substantially in excess of half said given diameter.
Claim 5
Dependent Claim
38 words
The fitting of claim 2, in which on the side of each V-shaped recess that is remote from said lug, each side wall is of lesser extent above said base than is the sidewall portion adjacent said lug.
Claim 6
Dependent Claim
31 words
The fitting of claim 2, in which on the side of each V-shaped recess that is remote from said lug, each sidewall slopes downward in the direction away from said lug.
Claim 7
Dependent Claim
28 words
The fittings of claim 1, in which the bottom of each V-shaped recess is characterized by an upstanding lug for anti-rotational engagement with stranded messenger wire or cable.
Claim 8
Dependent Claim
22 words
The fitting of claim 6, in which the effective height of said lug above said base is substantially half said given diameter.
Claim 9
Dependent Claim
26 words
The fitting of claim 6, in which the effective height of said lug above said base is less than the effective height of said side walls.
Claim 10
Dependent Claim
61 words
The fitting of claim 6, in which the effective height said lug above said base is such in relation to the spacing of the wire or cable reception in said V-shaped recesses that upon clamping a wire or cable between said bracket and clamp member and via said bolt, the plane of said base is substantially parallel to said base panel.
Claim 11
Dependent Claim
38 words
The fitting of claim 1, in which the displaced offset in said base panel is between two parallel slits offset within the lateral confines of said base panel, said slits extending substantially to the crest of said rib.
Claim 12
Dependent Claim
26 words
The fitting of claim 1, in which at least one of said apertures is square and said bolt has a square shank for square-aperture keying engagement.
Claim 13
Dependent Claim
18 words
The fitting of claim 11, in which the square aperture is in the base of said clamp member.
Claim 14
Dependent Claim
22 words
The fitting of claim 1, in which said side panels extend downwardly in substantially parallel relation, substantially perpendicular to said base panel.
Claim 15
Dependent Claim
20 words
The fitting of claim 1, in which said side panels are divergent in the downward direction from said base panel.
