Appl. No.:

10/754282

Inventors:

Ronald Jones - Racine WI, US
John Baker - Racine WI, US
Patrick McCarthy - Franklin WI, US
Jon Lindquist - Kenosha WI, US

International Classification:

B23P011/00
B21D039/00

US Classification:

029506000, 029505000, 029509000

Abstract:

This invention is directed to a method for joining, by axial movement, inner and outer metal pieces having different hardnesses. The method involves forming the harder piece to have a radial groove in its juncture surface. The harder piece has leading and trailing portions on either side of the radial groove. The leading portion is dimensioned to permit it to slide with respect to the softer piece and the trailing portion is dimensioned for swaging interference with the softer piece. Relative male-female axial movement is imparted to the pieces, thereby urging the junction surface of the softer piece along the leading portion of the harder piece until the softer piece engages the trailing portion of the harder piece. Relative axial force is applied for continued axial movement whereby the softer piece is forced past the groove such that swaging interference causes a portion of the softer piece to be upset into the groove, thereby creating a permanent joint between the pieces.

Patrick W. McCarthy - Milwaukee WI, US

International Classification:

A42B 3/16

Abstract:

A coupling assembly for safety headwear is provided. The coupling assembly includes one or more apertures within safety headwear, such as a hard hat, and a coupling structure that couples to the one or more apertures. The coupling structure includes one or more surfaces that interface with the safety headwear. The coupling structure includes a protrusion that defines one or more widths, and the protrusion extends through the one or more apertures.

International Classification:

G01B 3/1046
G01B 3/1005
G01B 3/1056

Abstract:

A tape measure including an elongate tape blade is shown. The tape measure includes a protective bumper that extends below the tape opening. The bumper is shaped to allow the tape hook to pivot during drop or impact to reduce the impact force experienced by the tape hook.

Inventors:

- Brookfield WI, US
Jacob Feuerstein - San Diego CA, US
Patrick W. McCarthy - Milwaukee WI, US
Collin D. Roesser - Milwaukee WI, US

International Classification:

G01B 3/10

Abstract:

A tape measure including a reinforced or coated tape measure blade is provided. The reinforcement layer is thicker than the metal inner layer of the tape blade. The reinforcement layer provides a reinforced tape blade such that the elongate tape blade may have a pinch load threshold of greater than 30 lbs. and/or a pinch height at break of less than 1.5 mm.
