6 Claims. (Cl. 176-29) I n Myi invention relates to electric lamps or simthe ordinary low melting point solders may be ar evices comprising one or more e1ectr1c enused. One which has given good results is comergy translation elements sealed in a bulb and posed of 40% bismuth 40% lead and 207 tin more pa icularly to the portions of such devices The mass of metal 39 also preferably encl ses a 53181195231125 tahedcziilnectigns between the leads of metal collar 20 which is securely clamped to the 5 Althou h n lli te external electr cal c rcuit. nsulation 2i on wire l8. The collar is smallest particfiarlyldal 'l ed o deii t e in vfhi li 3 131 3211.; a l dlmireter at 22 sq as not to be easily pulled from emerge at different portions thereof, an example nfe gm a zi li f igg fi i fi igf z s h g is the double-ended lamp, the leads of the outer orifice of the pocket smallez' in cro s fi w w ic emerge at opposite ends. My invention is particularly adapted for application to lamps used iy gg y gfig 2 322 2 2 :5 of n fi in strings for various decorative purposes such as y e p 6 Cu 8 Christmas tree ornamentation. According to my mg Sham aemg transferred to the bulb m 15 invention, the lamp bulb carries an extension in filf fi i fff g gg i i g $2 15 which the lead wire is sealed and the outer end t p a ng m w re an gl-ves portion thereof is hollow and receives the end of a S fa cqnneztlonfeven though the soldering an external conductor.

What I claim as new and desire to secure by Letters Patent in the United States is:

1. An electric lamp or similar device comprising a bulb having an extension, a leading-in conductor sealed in said extension and having its outer end extending into a pocketin said extension having an outer end orifice of smaller cross-section than the rest of said pocket and a mass of easily fusible metal located in said pocket andsurrounding said outer end of said leadingin conductor and having embedded therein an end of an external conductor.

2. A double-ended electric lamp or similar device comprising a bulb having extensions at either end in each of which is sealed a leading-in wire having its outer end extending into a pocket in said extension having an outer end orifice of smaller cross-section than the rest of said pocket and a mass of easily fusible metal located I in said pocket and surrounding said outer end of said leading-in conductor and having embedded therein an end of an external insulated conductor to which is crimped a collar which is united to said easily fusible metal.

3. The combination of an electric lamp or similar device and an external conductor constituting a device adapted to form part of a string of said lamps or similar devices with intervening lengths of said conductor, said lamp or similar device comprising a bulb having an extension, a leading-in conductor sealed in said extension and having its outer end extending into a pocket insaid extension, the end of said external conductor extending also into said pocket, and a mass of easily fusible metal filling a. portion of.

said pocket and securing together the endsof said leading-in conductor and said external conductor.

d, The combination of a double-ended incan= descent lamp or similar device and external conductors constituting a device adapted to form part of a string of said lamps or similar devices with intervening lengths of said conductors, said lamp or similar device comprising a bulb having an extension at each end, a leading-in conductor sealed in said extension and having its outer end extending into a pocket in said extension, the end of said externalconductor extending also into said pocket, and a mass of easily fusible metal filling a portion of said pocket and securing together the ends of said leading-in conductor and said external conductor.

5. The combination of an electric lamp and an external conductor adapted to form part of a string of lamps with intervening lengths of said conductor, said lamp comprising a bulb of vitreous material having an integral extension the end portion of which constitutes a pocket, a leading-in conductor having a portion thereof sealed in said bulb and an end extending into said pocket and a mass of easily fusible metal confined within the walls of said pocket and having embedded therein said leading-7m conductor end, an end of said external conductor being also embedded in said mass.

6. The combination of a double-ended electric lamp and external conductors one at each end thereof adapted to form part of a string of lamps with intervening lengths of said conductors, said lamp comprising a bulb of vitreous material having at each end an integral extension the end portion of which constitutes a pocket, a leadingin conductor having a portion thereof sealed in said bulb and an end extending into said pocket and a mass of easily fusible metal confined-within the walls of said pocket and having embedded therein said leading-in conductor end, an end of said external conductor being also embedded in said mass.
