Abstract
Abstract Apparatus for forming a support assembly for tines or the like comprises a retaining member which is inserted within a hollow support member to hold a series of brushes between the opposite walls of the support member and properly to orient them with respect to aligned pairs of facing deforming tools. The tools are actuated to cut apertures in the walls concentrically of the bushes and then to deform the edges of the walls around these apertures inwardly within the bushes so that the bushes are retained between the walls.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
74 words
Apparatus for attaching at least one projecting member to a hollow support of an agricultural implement, said member extending through an aperture in each of two opposite walls of said support, said apparatus comprising means for retaining at least one bush in place between said two opposite recesses in said hollow support and comprising at least one pair of aligned facing deforming tools for inward deformation of the edges of said two opposite recesses.
Claim 2
Dependent Claim
74 words
Apparatus for attaching at least one projecting member to a hollow support of an agricultural implement, said member extending through an aperture in each of two opposite walls of said support, said apparatus comprising means for retaining at least one bush in place between said two opposite recesses in said hollow support and comprising at least one pair of aligned facing deforming tools for inward deformation of the edges of said two opposite recesses.
Claim 3
Dependent Claim
37 words
An apparatus as claimed in claim 1, characterized in that each deforming tool bears aligned with it at its free end a punch tool having a diameter which is smaller than the diameter of the deforming tool.
Claim 4
Dependent Claim
14 words
Apparatus as claimed in claim 1, wherein said deforming tools have conical press surfaces.
Claim 5
Dependent Claim
38 words
Apparatus as claimed in claim 1, wherein said deforming tools are actuated by actuating means providing a tool pressure which is greater than the maximum tightening stress of a screw-threaded projecting member to be inserted through said apertures.
