To a?! Vlf/mm 'it may concern Be it known thatwe, Q'r'ro Fmi-amm, a subject of` the German Emperor, and residing at Charlottenburg, near Berlin, Germany, and MARCELLO von PnANr, a subject of thc King of Italy, and residing at'W'ilmersdorf, near Berlin, Germany, have invented a certain new `and useful Improved lrocess of Mounting Metallic Filaments on FilamentCarriers of Incandescent Lamps, of which the following is a speciation.
Uur invention relates to the manufacture of metallic filamentincandescent lamps.
It is preferable to employ as thin filament holders as possible for incandescent lamps having metallic filaments particularly in order to be able to fuse as large a number as possible of the holders at a sufficient dis` tance apart in as small glass 'beads as possible, in order to `diminish the conduction of heat from the filaments. In incandescent lamps, in which a continuous metal Wire is wound on the filament holders, one is limited however in the selection of the thickness of and the incandescent filament is then Wound,`
in the customary manner. Owing to the winding the filament obtains a certain tension,funder the influence of Which it Would contract lthe holders as soon as they are removed from the supporting device. In order to prevent this the filament is heated by a current passed through it before its re` lease from the holders. The heating may take place in the open air and a short rush of current suffices. The filament completely loses its tension and remains without tension in the position given to it.
Instead of supporting the thin holders by a special device, when the filament is being wound they may be relieved by simultaneously employing stronger holders, vvhose'sole A of example in purpose is to give the necessary resistance during the winding Operation. When-the winding is completed lthe incandescent lament is distentione-d in lilremanner by a 'l current and the strong holders` are `bent back so that the filament is -finally supported only f' by the thin holders.
Vri'niodified mode of carrying our process"- lntopractlce consists in 'placing'the vmetal filament firstly over irmfhooked' members which are connectedv With the yielding holders for the nal support of .the filament. After-the desired shape hasfbcen given to it the filament is transferred'frem the-'firm to the yielding holders.
011e form of filament carriereeniprising one form of lament holder for earrying'our process into' practice is represented-by way perspective in the aecompany- 111g drawing.
' Referring to the drawing, a designates the more resisting portion and b the very liable portion of a filament holder. Thef end c in the firm part t serves for'thelwindin'giof the wire, and' the bend d inthepliable part.
for receiving the Wir'e after 'it"has been wound. In order to -transferA-thewire from thel bend c to the bend d the .entirecarrying arm or holder is bent downwardvs'omewhat and replaced into its original position after lthe transference has ',beene'ected.'` Before 3 B5 the transference of the filament the wire is distentioned 'by an electric current, as de,
scribed above.
We claim 1-. The process of mounting continuous metallic filaments, which comprises Winding the filament back -and forth and resisting the tension-bf the Wire by rigid supporting means, passing 'electric currentl through the filament to distention it, and subsequently causing the filament to 'be supported by thin pliable holders. o -A 2. The process of mountingl continuous metallic filaments on thin pliable filament hoiders' unable to resistthe strain of Wind` ing the' filament, which 'comprises winding the pliable holders the sole. support of the ilament-` 1 10o ,p the filament over holders rigidly supported 105- 3. The-proeess-of -monnting zcontinuueament and dependent uponthe pliable holders.
-- 'metallic filaments on holders' which comi the `ilamentgpreliininarily` over 'firm sectmns of holders, e'ach holder comprising aI firm section and-a pliable sec-e tion, vpassing current -through the `filan'leiit lprises Windin 14, The process ofl mounting continuous to jdistention the same and, subsequently ransferring the filament to the'pliable sec'- ,'tion'of the holder'.
V5. The process of mounting continuous v metallic ilamentswhich comprises Winding the filament over the firm section of a per- :vman'ent holder comprising irm`and pliable i sections, passing current through the ila .ment to distention it and bending the indivi'dual arms othe holders inward to free.
v Copies of this patent may be obtained .fo five cents each, by addressing the Commissioner of Patents, Y
the, filament, transferring the Vfilament to the vpliahle section of Athe holders lattached to the free ends of the firm section.thereof and bending the individual arms of the holders back into their original position.
l 6. The method of nountinga ilament on 'yielding holderseah comprising a rigid re# sisting part and ayielding tip. Which consists"n Winding the lament on the .resisting part. oi? th holder and subsequently transferring the i'lament'tc the tip of the holder by'which itis finally supported. Y
The processof mounting y'continuous ilaments fon holders ,having a relatively rigid portion and a relatively'elastic p0r- "tion Whicl'consists in Stringing saidlilamentonthe rigid portion, heating it to give ita set,aknd transferring the filament to the elasticportion.
