US Patent:

49115910, Mar 27, 1990

Filed:

Jun 29, 1988

Appl. No.:

7/217131

Inventors:

Daniel V. Oaks - Troy MI

International Classification:

F16B 3704

US Classification:

411177

Abstract:

An improved fastener and method of attachment to sheet material providing attachment of a tubular fastener to sheet material by extruding, without severing, portions of the sheet material completely through openings on the base portion of the fastener. The extruded material is clinched on the top surface of the base portion by clinch members integrally formed with the base portion. The fastener is internally threaded, lightweight and preferably heat-treated prior to attachment to the sheet material to provide fastener strength equivalent to or greater than that of much heavier nuts. Two types of such fasteners may be attached by a method which opens up a hole in the sheet material of a larger diameter than the major diameter of the threads in the fasteners while simultaneously clinching the fastener in place. This eliminates the need to use thread-cutting bolts. The fasteners may be connected together to form a strip to be fed into an automated assembly unit from a dispenser.

Appl. No.:

8/147974

Daniel V. Oaks - Troy MI

International Classification:

B21D 5336

US Classification:

723792

Abstract:

A method for forming a saddle for a U-bolt clamp assembly which is suitable for clamping together the components of an automotive exhaust system. The method is capable of forming a saddle which exhibits sufficient strength and rigidity in order to generate a clamping load which can reliably join the exhaust components, while also being sufficiently resilient to accommodate variations in pipe size and hardness so as to reliably seal the joint formed by the components. The method of this invention produces a saddle structure which is relatively uncomplicated, and can be manufactured from a one-piece blank utilizing a series of conventional forming operations that offer a relatively low cost manufacturing process suitable for use in mass production.

International Classification:

B23P 1900

US Classification:

29 211

Abstract:

A fastener and method of attachment of such fastener to sheet material to provide attachment of a tubular fastener to the sheet material by extruding, without severing, portions of the sheet material completely through openings on the base portion of the fastener. In one embodiment of the invention, the extruded material is clinched on the top surface of the base portion by clinch members integrally formed with the base portion. The fastener is internally threaded, lightweight and preferably heat-treated prior to attachment to the sheet material to provide fastener strength equivalent to or greater than that of much heavier nuts. Two types of such fasteners may be attached by a method which opens up a hole in the sheet material of a larger diameter than the major diameter of the threads in the fasteners while simultaneously clinching the fastener in place. This eliminates the need to use thread-cutting bolts. The fasteners may be connected together to form a strip to be fed into an automated assembly unit from a dispenser.
