THOMSON-HOUSTON ELECTRIC COMPANY

How To ID A T-H Socket

The first Thomson-Houston sockets used baseless bulbs as shown below.
The early red fiber version though still sold after 1890, predated their patent for it which was applied for in 1889.

Thomson-Houston 1885 Baseless
Thomson-Houston 1885-1891 Fiber
Thomson-Houston 1891 Porcelain

Just because a socket has the T-H style base (screw thread base), it does not make it a Thomson-Houston product.
There were many different manufacturers of this style socket.
The sockets shown below were made by the Thomson-Houston Electric Company.

The 1885 T-H Socket (1890 Patent)

Though the patent above was applied for on 01/17/1889 and approved on 05/27/1890, this socket was already being sold by Sawyer-Man which had been bought out by Thomson-Houston. The picture to your right was taken from an article in Electrical World March 27, 1886. This is shown as "A New Incandescent Lamp Switch" Also another picture describes this switch as "SAWYER-MAN Lamp with New Switch"

Early shells for this switch use the patent no. 363,183 which was an electric switch patent applied for 11/27/1885 and approved 05/17/1887


The 1890 Porcelain T-H Socket (1891 Patent Approved)

When the switch is turned to the ON position the brass contact bar on the key handle moves up to make contact with the bulb base, which makes the electrical connection.

This patent was applied for on 03-15-1890 and approved
on 05-05-1891
