US Patent:
39314952, Jan 6, 1976
Filed:
Dec 11, 1974
Appl. No.:
5/531665
Inventors:
Walter J. Dzaack - Glenshaw PA
Donald M. Cunningham - Pittsburgh PA
Frank T. Walton - Oakmont PA
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H05B 368
US Classification:
219463
Abstract:
The heating unit is particularly adapted for a stove panel and the like, and comprises a pan adapted to be supported on the panel, the pan having an opening in its side wall. A sheathed electric heating element has an active heating portion formed into a flat spiral, such heating portion being supported crosswise of the top of the pan. The heating element has at least two terminal portions extending downwardly from the active heating portion and laterally thereof, the terminal portions extending through the pan opening for connection to a source of electrical energy. A closure, formed of an elastic material, such as cured silicone rubber, closes the pan opening. The terminal portions extend through the closure and the latter cooperates with the terminal portions to provide a hinge about which the heating element may be pivoted to swing the active heating portions upwardly from its supported position on the top of the pan.

US Patent:
42107997, Jul 1, 1980
Filed:
Oct 4, 1978
Appl. No.:
5/948569
Inventors:
Walter J. Dzaack - Glenshaw PA
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H05B 308
US Classification:
219541
Abstract:
The invention is directed to a termination for a surface unit having a flat spiralled active heating portion and a single, downward and laterally-extending terminal leg. The termination is particularly adapted for a surface unit of the type shown in U. S. Pat. No. 4,010,350, issued Mar. 1, 1977, to Donald M. Cunningham, and assigned to the assignee of this application.

US Patent:
40399958, Aug 2, 1977
Filed:
May 4, 1976
Appl. No.:
5/682955
Inventors:
Frank T. Walton - Oakmont PA
Walter J. Dzaack - Glenshaw PA
Assignee:
Emerson Electric Co. - St. Louis MO
International Classification:
H01C 722
US Classification:
338295
Abstract:
An electric resistance heating element, comprising at least two elongated dielectric bodies, each having a plurality of openings extending longitudinally thereon in radially displaced, parallel relation. Three metal pins fit into openings in the dielectric bodies and at least certain maintain the latter in longitudinally aligned relation. A resistance wire is wound on each of the bodies, each wire having longitudinally spaced terminals. One of the terminals of each resistance wire is electrically connected to one pin; the opposite terminal of one resistance wire is electrically connected to a second pin; and the opposite terminal of the other resistance wire is electrically connected to the third pin, whereby the one pin serves as a common electrical connection for both resistance wires, and the second and third pins serve as separate electrical connections to the respective resistance wires, whereby separate electrical circuits may be established within the heating element. Our invention also makes it possible to provide three phase electrical connections between resistance wires separately wound on at least three dielectric cores. This is accomplished by properly orienting the cores so that the opposite terminals on each are aligned for electrical engagement with three terminal pins which pass through longitudinally aligned openings in the cores.
