BESISTAE'CE UNIT,
Specification of Letters Patent. 7 Patented D 19 1916 Application filed ()etober '25, 1915. Serial No. 57,720.
To all whom it may concern I v Be it lmown that We, Gnonen H. DORGELOH and Eo ne Ports citizens of the United States, at Schenectady in the or? T rial between the turns of the spiral base to form a spacer for the resistance element.
For fuller understanding of our inventic-n reference may be had to the accompanyi'ng drawing, in which Figure l is a side elevation, partially broken away and partially in section, of a resistance unit embodying our invention;
- Fig. 2 is an and elevation thereof; Fig. 3 is a side elevation of one of the sections of the spiral insulating base; Fig i is a side elevation of one the sections of the insulating septum; 5 is a side view of a portion of the insulating base with the insulating septum between the spiral. portions thereof; and Fig. 6 is a side elevation of one of the insulating annuli located at the end of the unit.
Referring, now, to the drawings A is a spiral base of insulating material, such as asbestos compound or the like, formed of any number or sections 10. These sections are preferably formed with a part cut away at 11 so as to form less than one turn of the spiral. This insulating base is preferal/ 7; thoug h not necessarily mo member 12 which is tube of insuiati- A septum mica is recent .e of the insulati: g based preferably formed of section which sector cut away, septa :ms with the 2 grooue. within which the reszstanc D merit 1G received the septum thus const;- tilting spacer for the resistance element.
Preferably, he resistance element is in the form of a compound helical resistance member through which an insulating cord 17 of a material such as asbestos may be thgeaded to hold the same in position. An insulating disk or annulus 18 is located at either end of the resistance unit and is preferably ro vided with slots 19 through which the ends 20 of the resistance element extend. These ends are connected to terminals comprising a split clamping ring ,2 within which a connecting terminal 23 received.
In assembling, one. of the terminals is clamped to the member 12, and the ring 18 slipped over the tube 12 and brought into engagement with the terminal. The sec tions 10 of the insulating base and the secthe spaces formed between the successive Preferably,
turns of the insulating base. the insulating septum is formed of a double layer of insulating material, with overlapping oints. It will be apparent that a resistance unit of this character may be conveniently made up in any lengths desired.
In accordance with the provisions of the patent statutes, we have descri ed the principle of operation. of our inve n, together with the apparatus which "w consider to represent the best emb but we desire to have it c apparatus shown is that the invention can be carried out by other means.
What we claim'as new and desire to secure by Letters Patent of the United. States, is:-- 1. In av resistance unit, a spiral base of insulating material and a septum of insulating material received between the turns of the base to form a spacer for the resistance elem nt.
resistance unit comprising a spiral sulating" material, a resistanceelespirally thereon, and a septum gr material between the turns of forming a spacer the turns L resistance element.
resistance unit comprising a spiral sulating' material, a rigid member through said base, and a septum lating material between the turns of the support and forming spacer for the resistance element.
formed in sections and forming a spacer for the resistance element. i
5. A resistance unit comprising a spiral base of insulating material formed in secltions, and a septum of insulating material formed from insulating annuliwith sectors cut away, and received between the turns of the base support.
6. A resistance unit comprising aspiral base of insulating material, a compound helical resistance element wound thereon, a
rigid member extending through said base, and a septum of insulating material received between the turns of the base support to form a spacer for the resistance 2 element.
7. A resistance unit comprising a spiral base of insulating material formed in sections, aseptum of insulating material 'be tween the turns of the base, insulating disks at the endof the resistance element formed with slots throughwhich the ends of the resistance element pass, and terminals for said resistance element.
8. A resistance unit comprising a spiral base of insulating material, a compound helical resistance element wound on said base, a septum of insulating material re ceived between the turns of said base to form a spacer for the resistance element, and an insulating cord'threaded through the resistance unit to hold the same in position.
In witness whereof we have hereunto set our hands this 21st day of October, 1915.
