Patent number: 10717252Abstract: Provided is an article of cookware and a method of making the same. The cookware has a multi-layer bonded composite wall structure having an inner metal layer and an outer metal layer, and a core layer between the inner layer and the outer layer. The core layer has at least two perforated graphite plates, each plate having a plurality of spaced-apart holes formed therethrough, and at least one intermediate metal element disposed between the at least two perforated graphite plates and extending through the plurality of spaced-apart holes of each of the at least two perforated graphite plates. The at least one intermediate metal element is metallurgically bonded to the inner layer and the outer layer at least through the plurality of spaced-apart holes.Type: GrantFiled: June 8, 2018Date of Patent: July 21, 2020Assignee: ALL-CLAD METALCRAFTERS LLCInventors: William A.

Patent number: 10478012Abstract: A method of making cookware containing a bonded composite comprising the steps of providing at least two layers of materials by pressurizing and heating wherein the first of the at least two layers of materials has a plurality of spaced-apart bubbles formed on its surface, defining a cooking surface of the cookware, and a second layer of two layers of material is bonded thereto, wherein the bonding between the bubbles and the second material is of a lesser degree than the bonding between the first and second layers of materials in areas intermediate the bubbles, whereby a coefficient of heat conductivity is greater in the intermediate areas than in the bubbles. The method also includes providing a plurality of sets of bonding blank assemblies by solid state processing under pressure and heat.Type: GrantFiled: January 3, 2018Date of Patent: November 19, 2019Assignee: All-Clad Metalcrafters LLCInventors: William A. Groll, John Watkins

Patent number: 9756979Abstract: A device for holding a lid to a pot to permit the pouring of liquid from the pot while retaining a food product within the pot, including a pair of spaced apart hook members attached to opposed top edges of the pot and positioned off-set from a centerline of the pot. The hook members each include a horizontal top flange turned inwardly toward the pot, whereby when the pot is moved to a pouring position, the liquid forces the lid to separate from the pot and the top flanges of the hook members to engage the lid to maintain a predetermined pouring gap between the lid and the pot and also to prevent the lid from sliding forward off the pot due to their off-set positioning from the pot centerline.Type: GrantFiled: October 8, 2012Date of Patent: September 12, 2017Assignee: All-Clad Metalcrafters LLCInventor: William A. Groll
