Abstract
Abstract A device for readily mounting and adjusting an annular die ring in a die box, characterized by two cradle members movably mounted on a base and aligned to support a ring, releaseable opposite clamping means, preferably a pneumatically operated piston, means attached to both of the cradle members and extending away from the die box to move the cradle members in tandem, generally in the plane of the ring, and means attached to the cradle members and extending away from said die box to move the cradle members toward and away from each other in the plane of the ring. The tandem and relative motion provide adjustment in two different directions along perpendicular axes. In a preferred embodiment, the tandem adjustment means is a screw piece carrying an independently rotatable shaft. The relative adjustment means comprises the same shaft, which has oppositely threaded portions in each of the cradle members, and a gripping means to turn the shaft.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
170 words
A device for mounting and adjusting an annular die ring in a die box, said die being of the type having a periphery of substantially circular profile and presenting an inner surface of circular profile defining an aperture through which a ram will extend, comprising: a base and die box structure; first and second cradle members movable mounted on said base and aligned to support said ring at two points on one half of the periphery thereof; releaseable clamping means associated with said die box structure in a position substantially diametrically opposite said cradle members to hold said ring against said cradle members; first means attached to both said cradle members and extending outside Said die box to move said members in tandem generally in the plane of said ring and tangentially of said ring; and second means attached to said cradle members and extending outside said die box to move said members relative one to the other in opposite substantially tangential directions generally in the plane of said ring.
Claim 2
Independent Claim
170 words
A device for mounting and adjusting an annular die ring in a die box, said die being of the type having a periphery of substantially circular profile and presenting an inner surface of circular profile defining an aperture through which a ram will extend, comprising: a base and die box structure; first and second cradle members movable mounted on said base and aligned to support said ring at two points on one half of the periphery thereof; releaseable clamping means associated with said die box structure in a position substantially diametrically opposite said cradle members to hold said ring against said cradle members; first means attached to both said cradle members and extending outside Said die box to move said members in tandem generally in the plane of said ring and tangentially of said ring; and second means attached to said cradle members and extending outside said die box to move said members relative one to the other in opposite substantially tangential directions generally in the plane of said ring.
Claim 3
Dependent Claim
33 words
The device of claim 1, wherein said first means comprises a first member movably mounted in said die box structure and carrying an independently rotatable shaft which is attached to said cradle members.
Claim 4
Dependent Claim
39 words
The device of claim 2, wherein said shaft has oppositely threaded portions attached to said cradle members and has a first gripping portion outside said die box to allow rotation of said shaft, said shaft comprising said second means.
Claim 5
Dependent Claim
22 words
The device of claim 3, wherein said first member comprises adjustable screw means having a second gripping portion outside said die box.
Claim 6
Dependent Claim
17 words

Claim 8
Dependent Claim
45 words
The device of claim 6, wherein said position determining means comprises a duplicate dummy adjusting ring having an inner surface defining a multiplicity of spaced apertures in separate fluid communication with air supply means, and gauges to determine air flow through each of said apertures.
Claim 9
Dependent Claim
21 words
The device of claim 4, further including means to determine the position of said ring relative to a fixed ram therethrough.
Claim 10
Dependent Claim
45 words
The device of claim 8, wherein said position determining means comprises a duplicate dummy adjusting ring having an inner surface defining a multiplicity of spaced apertures in separate fluid communication with air supply means, and gauges to determine air flow through each of said apertures.
Claim 11
Dependent Claim
17 words
The device of claim 9, wherein said releaseable clamping means is actuated by a pneumatically operated piston.
