RARE THOMSON HOUSTON Threadless Base 1885 patent Antique Light Bulb / Lamp:
$200

Thomson – Houston Electric Company electric light bulb.

2 patent dates are visible, 1879 and 1885(I didn't want to disturb the original sticker to get the months.)

There is no exterior threading but the inner hole at bottom is threaded. I believe this is still what collectors would term as threadless.

Measures about 5 1/4" long.

The filament is still intact but I have no way of testing. Thomson -Houston merged with General Electric -Edison Companyaround 1894. Sockets did notbecome standardizeduntil around 1912.

Condition is excellent on this. It was found encased and very well protectedin some crochet with a woven basket bottom to create what looked like a miniature hot air balloon. I had to cuta thread on the crochet balloon but it could easily be reused and I will include this in the sale.

The following passage comes from the Thomson-Houston Electric Company catalog dated 1890:

“The incandescent lamps used with the Thomson-Houston Dynamo for incandescent lighting are superior in many respects to lamps of other makes, being manufactured under the well known Sawyer-Man patents. Owing to a special method of treatment during the process of manufacture, used only by this company, the carbon filament, though similar to that used by other manufacturers, gives this lamp superior advantages. It has a distinctive form, a quarter turn being given to it, which permits an equal radiation of light in all directions. Under repeated tests the life of these lamps has greatly exceeded the guaranteed number of hours, and at the same time they maintain a uniform candle-power without blackening of the bulb. They are made for long-distance incandescent light, using the transformer system; for use with Distributors; in series on Arc Lighting circuits and for Direct Current Lighting by low-tension currents.

Sorry but no buy it nows.
