' l li JlfL'EIMLTING ELECTRIC GLOW-LAMPS.
Patented Feb. t, 193.3.
Application filed Lug'ust 30, I911. el-tel I010. 546,810.
To all whom it may conccmx Be it known that l, ERNST Anonsr Kntisns, subject of the German Emperor, residing at Seehausen, Altmark, Prussia, in Germany, have invented a certain new and useful Improved liilethod of Regenerating Electric, Glow-Lamps, of which the follow inn; is a specification.
The proved method of, end apparatus for, regenerating burnt out-electric glow lamps by providing them with new filaments. The novelty resides in the manner in which the cemented joints connecting the filament to the electrodes are dried, the black deposit inside the glass bulb being also removed hi the some time.
The method hitherto adopted consists in melting? the cemented joint conductive by drying it with the aid or an electric arc,
which frequently results in damage to tie filament joint, and in removing the black deposit inside the bulb by heating the latter with a blow lamp, which causes intense and rapid local heating and is also liable to cause breakage. These drawbacks are obvi ated by the present invention, according to distributed, as regards the bulb, so that there is no risk ofbrealmge.
The invention is illustrated in the accompanying drawing, in which- Figures 1, 2 and 3 are vertical sections of the apparatus, eachshowing a different appliance for effecting the heating of the bulb. Referring in the first place to Fig. l, the
apparatus shown comprises a box ac, into.
which is inserted the bulb b of the glow lamp, the cap a or the lamp remaining outside. The box may be constructed to simul taneously hold any desired number of lamps in this manner. The new filamen g is introduced into the lamp bulb through the opening 6, and is fastened to the leading in- Wires 0, c by means of cement joints d, al The closed box or chamber is then heated up to the desired temperature by means of a burner f inserted into the box. The cap a, howerer, is not heated with the other parts of the lamp and may be subjected to e current or" cold air to insure its being kept present invention consists in an imcool. Instead of inserting the burner, the box may be heated from outside. The cemented joims are dried very rapidly in this manner and the black deposit in the bulbs 79 is simultaneously removed, instead of requiring, as heretofore, the heating of each bulb separately With ablow lamp, manipulated by hand.
In the modification shown in Fig. 2, the lamp 2), held together with e nizmber of others, not shown, in the box, also has its cap a outside the box and has three leadingiii-wires c, (2 0 to which the new filament is fastened by cement joints (Z, al (Z The cementedjoints are in this case dried and heated by introducing highly vheated air into the bulb by means of the tube 9 inserted in the opening 6. The current of air may be directedagainst the cemented ioints so that the same are rapidly dried. its the Whole lamp, with the exception of the cap, is inclosed in a chamber, the heat is concentrated as much as possible, and the deposit in the lamp bulb is likewise removed. The drying 1 of the cement and the removal of the black deposit may be synchronous or successive, operations. In the latter case the tempera .ture in the inclosed chitmber, or of the air introduced thereinto, is 'at first only raised suiliciently to dry the cemented joint, Where-j upon the temperature is gradgually increased until the black deposit entirely disappears. In the first case the temperature is some What higher to begin with, so that the ocmerited joint is dried and the deposit is removed from the bulb simultaneously.
The improved method may also vbe carried into effect during the production of the vacuum. The lamps are for this purpose placed in the inclosed case and heated after the connection with the vacuum pump has been made. In this case again. the cemented joint is dried simultaneously with the re-' -moval of the depositfrom the interior of the bulb, but, of course, the lamp bulbs can only be heated externally after having been placed in the inclosed chamber to be heated, the caps again being arranged outside.
The operation may also be carried out by drying the cemented joints, as shown in Fig. 3, by beating them by means of the heat developed by an electric current. For this purpose a spiral wire it, heated to the desired degree by the electric current, is intro duced into each lamp bulb b at e and placed also. 7
The three niethod'o'of i. iting,'il1ustrated in the drswihftg', may aiso'be combined in e suitable umrmerv I The method is applicdbie to CHIbOIl filer merits and also to metal filemeut iamps.
VVhet-I claim as my invention and desire to secure by Letters Patent ofifthe Undead States is: i
1. The method ofregeriemting an electric glow lamp by cementing a new filament to the electrodes we heating the oemented joints to o temper eture of from 270 to 320 C. epproximotely; by which the cement is emme dried and the deposit inside the bulb of the lamp removed.
2. The method of regenerating an electric glow lamp by cementing a nc.v filament to the electrodes, heating the cemented joints to atemperature at which they become-dry,
on'd gradually continuing the increase of temperature in such manner as to remove the deposit from inside the bulb.
In witness whereof I have signed this specification in the presence of two witmesses.
