Electric Cartridge Heater With Metal Sleeve Adapter

US Patent:
3937923, Feb 10, 1976
Filed:
Apr 28, 1975
Appl. No.:
5/572054
Inventors:
Herman P. Smith - Monroeville PA
Assignee:
Emerson Electric Company - St. Louis MO
International Classification:
H05B 306
US Classification:
219523
Abstract:
Cartridge heaters are most frequently used for heating metal parts by insertion into bores in such parts. Such heaters are manufactured in various diameters to closely fit within complementary bores to provide heat according to required specifications. My invention makes it possible to use a heater of known sheath diameter in bores of larger diameter, by use of metal sleeve means which have an inside diameter to closely receive the heater and an outside diameter to closely fit within the bore.
