-I1rance, and a resident of Iaris,'France, have invented a new and useful Improvement in and Relating to-Electrical Resist-slices, which ..-=improv ement' is -fuily.se t forth jinthe follow- -;,inmspeoilicatioa, Q -.,-}.--Electrieail resistances. are more and more generally employed in electrical work at the ,presenttimm. A rcsisteuce is generally constituted by a wire through which the current is passed. The electrical energy is transformed into calorie energy and then dispersed by couductiyi tyand radiation. Electrical rc- -sistanecs have numerous applications sueh,
' for example, as the starting'of motors, regulat ngdamps, heating, the. There is therefore the greatest possiblemterest in securing a simple economical but strong form of resistanc'c.
This invention has for its object to form an electrical resistance presentingall the prop-- cities which have been enumerated.
In the accompanying drawings, illustrative 1 of one embodiment of the invention, Figure 1 is a'view of three insulating-beads such .a'sused in my invention, two being shown in front elevation and one in side elevation. Fig. 21s afrontclevation of a resistance fabric constructed according to my invention .and embodyingu continuous conductor. Fig. 3 issya'front elevation of aresistance fabric of 1 slightly'diflerentarrangementiu which anumberof conductors are employed. Fig. 4 shows -.two similarbeads such as employed for insula'ting theside edges of the resistance fabric,
one beadbeing shown in transverse section through one of the openings orbores and the .btiher-fbad .in f front' clevation.-' Fig. 5 is a vfront.elevation of a modified form of resist .unce fabric, and Fig. 6 is a frontclevstion of aifurther modified form ofresistance fabric able'kindk such, for example, as glass, porce- ]ain, or the like. A wire otsuitable'rnetal-f such .as Ucrmanflsdvermr on, or thejlikceis threaded. through 'agcertain n um her of beads,
'suchas the row 3, Fig.2, halfnt the bottom and- ,ha'lfat the top. I W hen the widthdetermined Specification of Letters Patent; ,Applieatieufiled in, as, 1904. Serial No. 209,246.

upon hasbeen reached, this wire is turned and threaded upon the opposite side. passing italtcrnately through the-bottom holes,.which'have been left vacant in the beads of the upper row, and through the top holes of.,the new bonds, which are used as occasion requires. The new beads are arranged in the intcrva ls remaining ,vacant irrthe upper row. -When the end of the side is reached, Fig. 9, turning is again effected, and so on in succession, always with the same wire, which may thus be as long as desired. il"l1en liuished, the whole presents the appearance of a large Gallc chain, the links of which are the beads and the pins the conducting-avire, but with this dillerence, that the Pins or axes as a'wh'ole forma continuous conductor. So far the conductor has been assumcd to be in one piece; but it is equally possible to, ell'cct each threadingupou a sepa- 'IRt-O wire, as shown in lfig. 2, and in this case such connections as are considered desir- ,able may be made between thoextrcmities (i, v7,8, 9, 10, 11,12, 13, and' so.ou. These wires may be connected up in parallel for electromotive force, and so on, according torequire ments. In connecting, for example, by a connection 6 8, 9 11, 1O 12 a continuous conductor will be obtained between 7 and '13. It will beunderstood, therefore. from what has been stated that with suitable beads wellselcctcd and strongwircs, resistance elements as large as desired may be formed, corresponding to any given resistance and to a given dissipation of watts. A. fabric or web forming a perfect resistance unit is thereby constituted. i
It will, of course be understood that it is possible to make theheads of any suitable form adapted fort-ho purpose in view; For example, it will be noted that the fabric or sheet is perfectly protected except at the edges and that if the beads adjoin the conductor can not he touched. This feature is of the greatest importance in the construction of rheostats, as it obviates accidental and dangerous derivations of current. For the-edges a special-bead may be employed, which isprovidcd -with a slit. In this slit the turns, such as 3 and 4, may be laid. This head in: y advanta- "goouslypresent the 'form illustrated in Fig. 4; butitwill ofeourse be understood that any appropriate form may be selected.
hitherto been referred to; butordinary beads with one hole or beads-offtliis kind specially AVAELABLECGP made may be used, as shown in Fig. 5. The purpose of the two kinds of beads or buttons will be readilyapparent; Those with one hole serve exclusively to cover the wire. Those with twoholesalso serve toestablish mechanical connection betweenone row and the next. Finally, by an-extension of the idea, but with cut departing from the principle of the invention, beads witlrmore than two holes maybe employed. Three or r. y desired number of holes may be used. .Fig; Ggires anexample of fabric made with beads presenting-three holes; butI do not wish to confine myself to this example, as any number of other arrangements mighthe devised The holes, wr example,'need not be in the same plane, sothattwo distinct planes-for the; wires-maybeformed.
