PORATION OF MICHIGAN.
ELECTRICAL HEATING UNIT.
Specification of Letters Patent.
Patented Sept. 21, 1915.
Application filed October 16, 1909. Serial No. 523,016.
To all whom it may concern:
Be it known that we, FRANK KUHN and FRANK E. SHAILOR, citizens of the United .JStates of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvementsin Electrical Heating Units, of which. the following is a specification, reference being had therein to the accompanying drawings. I
The invention relatesto electrical heating units designed for use in various constructions of electrical heaters, and it is the ohthe invention to obtain a thoroughly ance, and one in which the-heat is dissipated through conduction from all portions of the resistance. r
To this end, the invention. consists In the construction as hereinafter set forth.
tive view of one form of unit; Fig. 2 is a perspective view with a portion of the armor and an insulating plate broken away, of a slightly modified construction, the resistance element being diagrammatically shown Fig. 3 is a conventional section On line w-w,
plates in firm contact with the mica and resistance throughout their extent, a plurality of intermediate stays F are employed and these as shown, are in the form of hollow rivets which pass through the insulating plates and armor plates but avoid the resistance. I
G are terminals which in the construction shown in Fig. 1, are mechanically secured to H attached to the ends of the plates C and D by rivets J. The ends I of the resistance are clamped between the flange K on the terminal, and a washer L,
the several parts of the terminal being suitably insulated from' the plate H.
In Fig. 2 the support for the terminal is formed by an integral extension of the plates and D but the resistance is con: nected to the terminal in the same manner as described in connection with Fig.1.
In use the construction of the unit de- SCIIIbGU. will-be thoroughly protected from 1n ury and from short circuit, and at the same time the heat is dispersed with almost as great facility as from the base resistance.
What We claim as our invention is:
1.7 A flat heating unit, comprising a flat resistance element, fiat insulation upon opposite sides of the resistance, a flat armor inclosing the resistance and insulation and firmly clamping the insulation and'resistance therebetween, and plug engaging ter- In the dra-vvings-F1gure lwis a perspec 2. A flat heating unit, comprising a fiat resistance element, flat insulation upon opposite sides of the resistance, a fiat armor inclosing the resistance and the insulation and firmly clamping the resistance and insulation therebetween, said armor having a projection, and plug engaging terminals rigidly carried by said projection and insulated therefrom, said resistance, armor and terminals forming a unitary structure.
'3'. A flat heating unit, comprising a flat resistance element, flat insulator plates upon opposite sides of said resistance, armor plates parallel to the insulator plates positioned upon opposite sides of the latter and united to each other at the margins thereof, a plurality of spacer; hollow rivets passing through said insulator plates and armor plates to prevent bucklin thereof, and plug engaging terminals carried by said armor plates and forming a unitary part of the I nnited to each other at the margins thereof, n
' In testimony whereof We afiix our signatures 1n presence of two wltnesses.
