Abstract
Abstract A fence dropper which may be used as a spacer or a post and which is suitable for supporting the wires of a wire fence, the fence dropper being provided with a series of tongues each of which is joined to but spaced from one edge of the body portion by a root. Each tongue is provided with a forwardly extending portion and a return portion which constitute with the body of the dropper a wire retaining aperture, but since the tongues are spaced from the dropper by their roots, the tongues form with the dropper edge slots in a plane which is at right angles to a fence, the arrangement then being such that a dropper may be positioned against a fence with wires in respective slots and rotated through 90° whereupon the wires become contained within the wire retaining recesses.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A method of forming a fence dropper having a body portion with a plurality of tongues spaced from one another and lying beyond one edge thereof, comprising forming a sheet metal blank into two said body portions of similar cross-sectional shape which extend away from a plane and are joined together by a flat bridging web which lies in that plane, shearing the flat bridging web to simultaneously blank the profiles of said tongues in their flat form, and respective webs joining the roots of the tongues to the body portions such that each tongue is of similar size and shape, and the recess formed between a said tongue and the body portion from which it is spaced by said root and also between that said tongue and an adjacent said tongue has its size and shape similar to the tongue size and shape, and then forming each said flat tongue to provide therein a return portion which extends forwardly of but terminates rearwardly of said plane to thereby define with said body portion a wire retaining aperture.
Claim 2
Independent Claim
178 words
A method of forming a fence dropper having a body portion with a plurality of tongues spaced from one another and lying beyond one edge thereof, comprising forming a sheet metal blank into two said body portions of similar cross-sectional shape which extend away from a plane and are joined together by a flat bridging web which lies in that plane, shearing the flat bridging web to simultaneously blank the profiles of said tongues in their flat form, and respective webs joining the roots of the tongues to the body portions such that each tongue is of similar size and shape, and the recess formed between a said tongue and the body portion from which it is spaced by said root and also between that said tongue and an adjacent said tongue has its size and shape similar to the tongue size and shape, and then forming each said flat tongue to provide therein a return portion which extends forwardly of but terminates rearwardly of said plane to thereby define with said body portion a wire retaining aperture.
Claim 3
Dependent Claim
73 words
A method of forming a fence dropper according to claim 1 wherein each said body portion is formed to a `U` shaped cross-section and is flanked by a respective flange also lying in said plane, each said recess extending only partway across said bridging web, whereby the `U` shaped body portion of each fence dropper is flanked on both sides by flanges, and said tongues extend from one only of the two flanges.
Claim 4
Dependent Claim
21 words
A method of forming a fence dropper according to claim 1 wherein the body portion is formed to a "U"-shaped cross-section.
Claim 5
Dependent Claim
20 words
A method of forming a fence dropper according to claim 1 wherein each tongue is of identical size and shape.
Claim 6
Dependent Claim
28 words
A method of forming a fence dropper according to claim 1 wherein the shearing forms two fence dropper body portions, each body portion having a plurality of tongues.
Claim 7
Dependent Claim
20 words
A method of forming a fence dropper according to claim 5 wherein each tongue is of identical size and shape.
