To 1U whomy it may concern; i
Be it known that I, LAWRENCE E. BAiniiN- one, a citizen of the United Sintes, residing at Seheneciedy, in J[he County of Schenectady, Staie of New York, have invented ceiinin new and useful linpmvemenie in Insulaiin'g Materiel for Embedding Elec* li-ical, Conductors, of which the following is n speeihenion.
rlhie invention relates to improvements in ineulaiing compounds and has foi' its ob'jeol; Jdie provision of 21 material which is :in eleotiicel insulator of e high order in addition to being capable of withstanding a. high ieini'ieintui'e Without injury, which nl ordinary lenniei'eiuie will be suliciently plastic o permit oi embedding :i metallic conductor therein :ind `which will hin-den under steam lieatinent.
In my pieuious application, No. 274,409, filed Mey lllh, l905, ll have described and claimed e piioeees; Whei'eby ny mate "fil muy be produced. l have found, howevei, thai ihiel maeiisi'l possesses qualit-ies which make ih Very deoiinble :is a eiibsiance in which lo embed eleeli'iczil conductors. Ae disclosed in ihe ebovenientioned :ipplieniioin the mnieiiel may be hardened undei` Steam inentineni, e pressure of 150 lbs., eoi'iiesponding l'o n lenipeifniuie of 181 C., being- Sullieieni to harden ii in about live hours.
li has been commonheretofore to embed ci'indiielors in' Substances such as enamel,
which are lnsed around the conduolzoi' oi1 cementewhich 'are nir-hardened around ihe conductor. lnbennees like elaye or porci lfnn cannoli be need for oi'nbedding bocaux@ of the high lenipemtnie neoesszn'y foi' hsn (lening 'which would lend to elngginn' oi: lhe ineinl uil'li ille innulniion. ,Enamel nino line ille disndvunlnge of requiring heni which renders necessary mueh caro in application. is exi'ieneive und when ooinplel'ed will nel elnnd :my great ternpeiuiuie changesy with out munching und exposing (he eondln'loi'. lnmnelnl also oonduol when healed, conducilifiiy beginning juni. below redness :1nd inmenging; i'fi'pidly es the ieinpei'ni'ui'e niece.

desired that an insulating material. assume. l have found in hardening my materiel that it shrinks en amount just snfi'ieienl; to tighten n F 1 Land iiinily hold a eondnctoi' in place. lhe temperature at which it' ie formed iS 16W and the inatei'inl when formed will stand a high ienipeiziiui'e and is highly insulating, ni all temperatures. The inaeirinl uf'hile e. li'emely herd and strong; cen be inziel'iined when desirable ior Special shapes lapped foii seiews, etc.
ln carrying ouiJ my invention, the 'process used is the seme es that described in the abovementioned application. Ai qmlntity of asbestos or othei" fibioiisinnieiiel isinixed Wiih :i definite qunniiijv of calcium hydrate and flint, or eilieu. Other ineieiizile euch ne magnesium hi'di'nl'e oi" magnesium meid. may be used, ii'` beingl onliY eeeenlinl that neubnlunee be employed which will combine Wi'l'h Siliea lo i'oim n. silicate under steam tiene ment. it is preferable in mixingl nini'eiinle io be combined in l'hie "manner ilnil, ninounie corresponding io ihe molecular in'oi'ioi'iions be used: the nppionimnie formule oij the Silieno ioiined being` (feSiflflO. he nei'ceni'ugfe of ':itoii'fsi viiig somewhnl. For ineinnee when slnked linie and ilini' .fne uned in ho pi'onoilion of ifi lo (l0. llieie will be, no exc of eii'hel linie oi' llinl'. lhe exnei' inonoiiionn inni". howevel. he varied llnonggfhoul' u eonnideinble innige. und l have found (hul im' ceilziin (deseen of' noel( l'ho propo'iimis oi GCI nshentoe, 38C? dint und 295 calcium h'vdiziie give Vous eniiniinci'oiy i'esulls. Those ingredimin, :ililei' beine thoroughly mixed. ui'e moislened und block ot high insulating material; and Fig.
5 is an end view of the saine.
The form shown in Fig. l requires no description, since it merely shows one of the possible uses to which I l0. in the form ci a block having a stud 1l connected therewith, islfirmly embedded in the material.
In Fig.. 2 I. have applied my invention to a rheostat. The resistance conductor l2 may be embedded in the material in any desired inanneruasfor instance, by Winding the Wire about a glas/s rod 13 and then embedding the rods in ythe material as shown.
In Figs. l and 5 I have shown another possible arrangement. lIn this case I have formed a starting rheostat by embedding the rcsistances la in fthe material in the. manner shown in' F1g.-2 and .forming terininals for the sections o't' resista-nce by cnibedding studs'l5 after the manner shown in Fig. l. A controlling arm 16, pivoted at 1i', is arranged to successively engage the studs to vary the resista ice.
It will be seen rom the yforegoing that I have produced an insulating material which is exceedingly valuable as `an embedding substance for. metallic conductors. When hardened, it. becomes like slate or soapstoue, but has' theI advantage over these of being capable ot' lending itself readily to various forms by i'i'iolding vin addition t'o being/ capable ot being machined.
Many modilications of my invention will vsiiggest themselves to those skilled, in the art, and it should be understood that I do not limit my invention `to the materials o'r ,process ofV formingv and arranging'fsame Vherein motioned, but that all suchl medidcations wi'll come within) the spirit of my may apply my invention. In this case a metallic conductor iboebais `invention in sofar as they falll Within the scope of the claims annexed to and forming a part of this application.
What I claim as new and desire to secure by Letters Patent of the United States, isf- 1. A steamLhardened insulating compound having an electrical conductor embedded therein.
2. A steamhar dened insulating compound of silica and a hydrate having an electrical conductor embedded therein.
3. A steam-hardened insulating compound of an alkaline hydrate and silica having a metallic conductor'embedded therein.
