ELECTRIC SAD-IRON.
Specification of Letters Patent.
Patented N 0v. 10, 1914.
Application filed Kay 13, 1909. Serial No. 495,779.
To all whom it may concern Be it known that 1, WILLIAM S. HADA- WAY, Jr., a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, haveinvented a new and useful Improvement in Electric Sad-Irons, of which the following is a specification.
My inventidn relates to electric heating devices, and it hasfor its object to provide a simple and indestructible electrically heated sad iron or similar device and an inexpensive and eificient process for producing the same.
The single figure of the accompanying drawing is a transverse sectional view of a sad iron constructed in accordance with my the handle being omitted.
The structure here shown comprises a body 11 of cast iron or other suitable metal having a recess 12' which is formed by an upwardly projecting flange 14 and contains a resistance element 3 and a body 13 of Babbitt or other easily fusible metal.
' I prefer to construct the device as follows: A suitable resistance element 3 (preferably comprising a .strip or ribbon of steel having a plurality of slots cut alternately from opposite edges to provide a zig-zag ath for the electric current, as shown, -or example, in my Patent No.
pov'ered with a thin enmica ribbon which are placed on the respective sides; 0
the resistance ribbon and then to form a homogeneous body metal of insulation in which the resistance is embedded, when heat is applied. The insulated resistance is then covered with a sheath 5 of sheet metal and the metal clad element thus produced is properly disposed in the recess 12 of the base 11. The body 13 of Babbitt or other metal is then cast or flowed around the resistance member, the thickness of the sheet metal sheath 5 being such that it is fused and united with the casting without injuring the insulation. A sheet metal cap or cover 10 may then be fitted upon the body 11 to provide an air space above the heat-producing element of the iron.
v I claim as my invention:
1. An electric heating devicecomprising a metal base having a flange to produce a receptacle, a metal clad resistance element disposed therein, and a metal body which is poured or flowed into the receptacle around the metal clad resistance element.
2. An electric heating device comprising a flanged metal base forming a receptacle, a clad resistance element disposed therein and a body of metal having a rela--; tively low melting point, which is poured or flowed into the receptacle around the metal clad resistance element.
In testimony whereof, I have hereunto subscribed my name this 5th day of May,
