Support Clips And Insulators For Use In Electric Heaters And Electric Heaters Containing Same
view source
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.

Open Coil Electric Resistance Heater Using Twisted Resistance Wires And Methods Of Making

US Patent:

6737616, May 18, 2004
Filed:

Apr 2, 2003
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.

Standoff For Use With Uncoiled Bare Wire And Insulated Runs Of An Open Coil Electric Resistance Heater, Method Of Use, And An Open Coil Resistance Heater Using The Standoff

US Patent:

7075043, Jul 11, 2006
Filed:

Jun 30, 2004
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.

US Patent:

7154072, Dec 26, 2006
Filed:

Dec 3, 2004
Appl. No.:

11/002671
Inventors:

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

Tutco, Inc. - Cookeville TN
International Classification:

H05B 3/06
H05B 3/08
H05B 3/16
F24D 5/10
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.

US Patent:

7947932, May 24, 2011
Filed:

Nov 30, 2007
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.
