—The only known extant Spencer Electric Co., Potbelly Candlestick Telephone (serial no. 32!) Sold!

Spencer-Potbelly-Candlestick-Telephone Almost impossible to find, a telephone which is unknown to the large and very active community of telephone collectors, the Spencer Potbelly Candlestick Telephone. I could not find a picture or any record in any publication in the field of historic telephony, or on the Internet! The only records I could find are three patents issued to James H. Spencer and Malcolm S. Keyes, both of New York City, N.Y., a description in the Scientific American Supplement issue of January 29, 1898, and a description of the novel transmitter published in the Electrical World and Engineer, Volume 34, page 248.
There are many telphone related patents issued and no actual hardware was ever found; this was true about the US Patents with the numbers 596'834, issued on January 4, 1898, and the consecutive numbers 624'696, and 624'697, both issued on the same day, May 9, 1899, untill this telephone was found to prove that it was actually manufactured. The serial number of 32 is an indication that there where not many made.
This candlestick telephone with the novel form of transmitter patented by Spencer and Keyes was manufactured by the the Spencer Electrical Company, 163 Greenwich Street, New York City, N.Y.
A description of the novel transmitter, published in the Electrical World and Engineer, Volume 34, page 248, states: “The object of the invention is to avoid metallic vibrations, only the intended actual sound being properly transmitted. To accomplish this result, Mr. Spencer employs novel means of supporting the diaphragm,” read more>>

Thumbnail-image-of-item,-click-to-download-large-image!






This is an exceedingly rare version with the three cutting knifes of the Peerless Pencil Pointer. If you are an experienced collector, you know that the last one of these showed up on eBay two years ago with a buy it now price of $950.00. The machine sold as soon as it was listed.
Whittler applied for a patent and started manufacturing before the patent issued. In short order, he first manufactured a machine with just one rotating knife, then two, and finally three. The patent never issued and Whittler had to seize production, hence, the machine is very scarce, read more>>
