US Patent:

47948345, Jan 3, 1989

Filed:

May 15, 1987

Appl. No.:

7/049854

Inventors:

John A. Werner - Wauwatosa WI

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

B23D 2104

US Classification:

83185

Abstract:

A tube cutting apparatus for orbital shearing of tube stock in uniform lengths including a stationary die surrounding the tube stock placed adjacent an orbiting die of similar aperture, the orbiting die being rotatably mounted within an eccentric die holder which in turn is rotatably mounted on an axis offset from the stationary die with drive means for turning the die holder and causing the orbiting die to move in an orbiting path, and a two-section mandrel carried on an extendable ram which is removably insertable within the tube stock being cut, the first section being coaxially fixed to the ram while the second section has limited movement laterally relative to the first section, the second section having an inside diameter portion greater than the outside diameter of the ram and a elastic ring positioned between the second section and the ram to maintain the two sections in concentric alignment in the absence of outside forces.

Appl. No.:

7/571216

Inventors:

John A. Werner - Milwaukee WI

Assignee:

Toolrite Manufacturing Company - New Berlin WI

International Classification:

B23D 2304

US Classification:

83199

Abstract:

An apparatus for shearing extruded stock includes a stationary die and a rotatable die mounted adjacent one another wherein the rotatable die moves through a limited angle of rotation through the operation of a cam acting on a lever linked to the spindle in which the rotatable die is mounted. The cam undergoes a full 360. degree. of rotation although the rotatable die undergoes a limited angle of rotation. A spring or regulated pneumatic cylinder is provided to bias the rotatable die to the home position after cutting of the extruded stock.

Filed:

Dec 2, 1992

Appl. No.:

7/984595

Inventors:

John A. Werner - Milwaukee WI

Assignee:

Compression Technologies, Inc. - Eden Prairie MN

International Classification:

B21B 2706

US Classification:

72 69

Abstract:

An improved apparatus for the formation and production of cylindrical pressure vessels or tanks through metal spinning operations wherein the end caps of the vessels are simultaneously formed from a hollow, thin-walled cylindrical work tube rotatably supported within the apparatus. The arrangement is further designed to provide control of the distribution of the wall thickness as well as the profile of the end cap portion of the vessel so that the knuckle area may be of controlled thickness to increase durability and performance of the tank or vessel.

Filed:

Feb 11, 1976

Appl. No.:

5/657178

Inventors:

John A. Werner - Milwaukee WI

Assignee:

Besser Industries, Inc. - Roanoke IL

International Classification:

B21B 1706

US Classification:

72 75

Abstract:

A ball sizing machine for sizing an internal passage in a workpiece in which pressure is employed to force a sizing ball through the passage against a fluid counter-pressure. The opposite ends of a passage to be sized are sealed at each end with a tapered ram plug with the sizing ball within the head end of the passage. The passage is filled with a fluid, such as oil, from the tail end of the passage. When passsage has been filled from the tail end to a predetermined pressure, the system is conditioned to permit a metered flow of fluid out of the tail end when pressure is applied to the head end of the passage in front of the ball to force the ball through the passage.
