FRANK KUHN AND FRANK E. SHAILOR, OF DETROIT, MICHIGAN, ASSIGNORS TO AMERICAN ELECTRICAL HEATER COMPANY, OF DETROIT, MICHIGAN, A COR- PORATION OF IVIICI'IIGAN.
I ELECTRICAL HEATING UNIT.
Specification of Letters Patent.
Patented Feb. 11, 1913.
To all whom it may concern:
Be it known that we, FRANK KUHN and FRANK E. srriuLony'cit-izens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Electrical Heating Units, of which the following is a specification, reference being had therein to the accompanying drawings. i
The invention relates to electrical heating units, being more particularlydesigned for use in electrically-heated sad irons, and the invention consists in the construction as here inafter set forth.
In the drawings Figure 1 is a perspective view of the various parts composing the unit detached; Fig. 2 is a plan view of the unit complete, and Fig. 3 is a section on line xw Fig. 2.
In the construction of electrically-heated sadirons, it is desirable to distribute the heat over the bottom oi the iron, and par ticularly to conduct the heat into the point of the iron. This has been accomplished in certain constructions heretofore used, by forming the unit of a plurality of sections a, b and 0 arranged parallel to each other, with the centra-l'section b in advance of the sections a and c on opposite sides thereof. These sections must be connected to each other in series, and also connected to terminal contacts for the attachment of the conductor .cordQ 1 -Our improved construction is one which permits of assembling, clamping together, and electrically-connecting the several sections of the unit'wi'th an exceedingly simple and inexpensive construction of the parts. In detail, describing the sections 2, A is the heat-producing resistance, which is in the form -of' a flat conductor secured upon an insulator supporting plate B.
C and C are insulator plates arranged upon opposite sides of the plate B and resistance A, and D and E are clamping plates upon opposite sides of the insulator plate, which also forms the terminal connections for the resistance. The plates D and E comprise a heat conducting medium and are each of a size to substantially cover one face of the heating resistance, the plates C, C serving to insulate the plates D and E for substantially the'ir entire area from.
the terminal contact post I is, secured. The
plate E is also provided with a laterallyextending portion J, but this forms a connector to a plate K for the adjacent section b of the unit, the latter plate having the same relative position to the section b as the plate E. The plates E'ahd D of the section 0 however, are positioned upon the opposite sides of the resistance element from which they occupy in the'section a, while the heat conducting medium or plates of the section b comprises two plates K carried by the plates E of sections '0; and 0. Thus the bottom plates E and K of the adjacent units are formed integral witheach other, and form an electrical connection between. the two sections of the resistance.
To secure the parts together a U-shapcd member L is engaged with each section and the flangesl/ thereof bent down, the flanges L and the bottom L of the U-shaped membcr comprising. plates between which all the parts of the section are clamped. The flanges I, are. cut-away at L to avoid contact with the laterally projecting conductor portions F and J.
In assembling the "parts, the insulator strips C and C which are of slightly lesser length than the resistance A are so arranged that one end of the resistance A will be exposed for contact with the plate D, while the other end of said resistance will be exposed for contact with the plate EQ Insulator strips M'are also placed between the plates-D and E, and-the U-shapcd member L, and insulator strips N are arranged to cover the lateral projections F and J. Thus all portions of the circuit will be thoroughly protected, with. exception of the terminals G, which are arrangedto-be out of contact with any contacting paftffof-athesstructure. All of the parts of eaoh 'fsectionare apertured at O in al'inement"witlfieach-otherfor the insertion of'iscrewsorother fastening 1 I devices body to beheated; r
With the above described const-mctiorgth assembling of the parts will completdthe circuit through all of the sections which are I in series witheg'ighlother being connected by by whichthe 'unit-iswsegured to the theplates E and K and the integral portion J. These plates perform the further function of the heat conductors and distrib-uters, and together with the U-shaped member- L serve to holdthe heating resistance in firm contact with the insulating strips on opposite sides thereof.
What we claim as our invention is:
1. An electrical heating unit, comprising a flat insulated resistance and a fiat conducting plate extending over a considerable I portion of'the outer surface of the resistance and clamped thereto,- said plate forming a part of the electric circuit and having a terminal integral therewith.
2. An electricalheating unit, comprising a tortuous resistance, insulating plates on opposite sides of said resistance, and conducting plates clamped t-osaid resistance andextending over a considerable portion of the-outer surface of the resistance, one of said plates forming a part of the electric circuit arid having a terminal integral therewith.
3. An electrical heating unit, comprising a plurality ofsepa-rat-e insulated resistances,
and plates clamped to said resistances forming integral connections" therebetween.
4. 'An electrical heating unit, comprising a plurality of separate heating resistances, and plates clamped to said resistances inte gra-lly connected to each otherand'formin'g .tions.
the electrical connection between said resistances.
5. An electrical heating unit, comprising a plurality of separate insulated resistances, platesfclamped to said resistances integrally connected with each other;"sg'apar'ate co6p crating plates also clamped to' 'said" resistintegral terminal conneC- ances and having 6.

An electrical heating pro ect;ion struck up therefrom to" form a u comprising a plurality of separate fiat heating resistances, insulating plates embracing said resistances, plates clamped to adjacent resist-- ances integral with each other and forming an integral'connection between said resistances, and cooperating'plates also clamped to the end resistances having terminal connections formed integral therewith.
