Abstract
Abstract A swaging tool, for assembling hose to couplings, which permits a limited range of hose sizes to be swaged with one tool, while avoiding the undesirable formation of lobes, which lead to leaks. The tool has a plurality of outer dies arranged around one axis, the outer dies moving in a radial direction on opening and closing of the tool. Positioned between the outer dies are insert which also move in a radial direction on opening and closing of the tool. Both the dies are in contact with the hose assembly when the tool is closed, of which the following is a specification.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A swaging tool comprising a plurality of outer dies arranged around an axis, each outer die movable relative to and in unison with the other outer dies in a radial or a substantially radial direction with respect to said axis, a number of insert dies positioned between at least some of the adjacent pairs of outer dies, each of said insert dies being positioned in recesses formed in each of the dies of an adjacent pair of outer dies, means to circumferentially locate each insert die relative to the recesses of an adjacent pair of outer dies and each insert die being supportable by a shoulder formed by the recess in each of the outer dies of an adjacent pair of outer dies so as to be movable relative to and in unison with the outer dies in a radial or a substantially radial direction with respect to said axis.
Claim 2
Dependent Claim
150 words
A swaging tool comprising a plurality of outer dies arranged around an axis, each outer die movable relative to and in unison with the other outer dies in a radial or a substantially radial direction with respect to said axis, a number of insert dies positioned between at least some of the adjacent pairs of outer dies, each of said insert dies being positioned in recesses formed in each of the dies of an adjacent pair of outer dies, means to circumferentially locate each insert die relative to the recesses of an adjacent pair of outer dies and each insert die being supportable by a shoulder formed by the recess in each of the outer dies of an adjacent pair of outer dies so as to be movable relative to and in unison with the outer dies in a radial or a substantially radial direction with respect to said axis.
Claim 3
Dependent Claim
36 words
The swaging tool of claim 1, the tool having at least four outer dies and an insert die between each pair of adjacent outer dies, said tool composed of two parts separated by a diametrical axis.
Claim 4
Dependent Claim
68 words
The swaging tool of claim 2, comprising four outer dies, two of said outer dies being side dies, each side die being composed of two side die portions separated on said diametrical axis; each part comprising a central outer die; a side die portion positioned on each side of the central outer die; and an insert die positioned between Each side die portion and the central outer die.
Claim 5
Dependent Claim
30 words
The swaging tool of claim 1 in which the means to circumferentially locate the insert dies is compression springs housed in recesses formed in the outer dies and insert dies.
Claim 6
Dependent Claim
44 words
A swaging tool as claimed in claim 2 including a cover plate for each part of the tool, the cover plate fixedly attached to the center die, and means slidingly attaching the side dies to the cover plates, to permit the radial movement thereof.
Claim 7
Dependent Claim
36 words
A swaging tool as claimed in claim 2, the diametrical axis extending horizontally, and each part of the tool having an external shape to fit in a corresponding recess in a tool body of a press.
