US Patent:

6509554, Jan 21, 2003

Filed:

Apr 6, 2001

Appl. No.:

09/827323

Inventors:

Keith Howard - Cookeville TN
James Sherrill - Cookeville TN
Ike Walker - Monterey TN

Assignee:

Tutco, Inc. - Cookeville TN

International Classification:

H05B 306

US Classification:

219536, 174138 J

Abstract:

A clip for connecting one or two insulators to a rail (preferably a T-bar member) of an electric heater including at least one bendable metal clinching member, where the clip is securable to the rail by bending the clinching member around the rail. Preferably, the clinching member is one or two T-shaped end members disposed on transverse ends of the clip. Opposite end sections of the ridge of the T-shaped end member constitute clinching flaps which, in use, are clinched around a stem of a T-bar of an electric heater.

Appl. No.:

10/404086

Inventors:

James L. Sherrill - Cookeville TN

Assignee:

Tutco, Inc. - Cookeville TN

International Classification:

H05B 306

US Classification:

219536, 219537

Abstract:

An open coil resistance heating apparatus uses a pair of twisted wires having a particular gauge and pitch as the resistance heating wire. Using the twisted pair of wires in the selected gauge and pitch results in significant cost reductions; less wire is needed to achieve the same heating capacity.

Appl. No.:

10/879286

Inventors:

H. Keith Howard - Cookeville TN, US
James L. Sherrill - Cookeville TN, US

Assignee:

Tutco, Inc. - Cookeville TN

International Classification:

H05B 3/06

US Classification:

219548, 219536

Abstract:

An open coil resistance heater uses one or more standoffs to engage and support the generally straight or uncoiled run of bare or insulated wire that is part of the resistance wire of the heater. The standoff has slots, which are sized to engage the bare or insulated wires for support purposes, and is removably mountable to the heater frame for supporting the run of uncoiled wire.

Tutco, Inc. - Cookeville TN

International Classification:

H05B 3/06

US Classification:

219532, 219536, 219537, 219541, 219552, 219478, 392350

Abstract:

An open coil resistance heater assembly is made for universal mounting between left and right hand installations in an appliance or other equipment. The heater assembly has its coils arranged symmetrically about a bisecting plane of the heater assembly and/or a center line of its terminal assembly aligned with the bisecting plane. The symmetrical coil arrangement and/or bisected terminal assembly allow the heater to be used in right hand or left hand installations.

Appl. No.:

11/987542

Inventors:

James L. Sherrill - Cookeville TN, US
R. Devin Ridley - Cookeville TN, US

Assignee:

Tutco, Inc. - Cookeville TN

International Classification:

H05B 3/06
H01C 3/14

US Classification:

219532, 219536, 219537, 219535, 219541, 219552, 219476, 219477, 219478, 338304, 338305, 338319, 338320, 338299

Abstract:

An open coil electrical resistance heater uses a number of offset insulators to support the coil of the heater. The offset insulators configure the run of coil in a sinusoidal shape to hold the insulators in a more secure manner and reduce vibration and noise generation during heat operation. The sinusoidal configuration of the coil also reduces the problem of shadowing of portions of the resistance wire coil.
