PART I:


1005 THOMAS A. EDISON DUPLEX TELEGRAPH MODEL:(30KB) This model, manufactured in Edison's laboratory consists of a

1 X 2 Ft. board (28KB) with

a set of wires on the bottom (34KB). On this board, 3 wind-up clockwork mechanisms labeled "Terry Clock Co. Waterbury, CT, Pat'd Dec 1, 1868 are mounted.

Each clockwork mechanism has had its escapement removed and replaced with an air-propellor to govern its speed (47KB). Each clockwork mechanism turns a

rotating disk that makes contact with an adjustable wiper contact (46KB). The disk has an

insulated spot that breaks the contact at an adjustable point in its rotation (54KB). The device was an early experimental model of a form of mechanical time-division multiplex designed to allow 3 telegraph messages to be sent on the same line.


1010 * K1BH's TRANSATLANTIC CABLE KEY:(32KB) Small double (plated) lever key with ivory knobs on Gutta-Perchia base stamped: Edouard BOUTY. Constructeur. Traded to K1BH, 1995.


1011 * VERY EARLY EUROPEAN SUBMARINE TELEGRAPH CABLE KEY: (61KB) This is an unusual and very early cable key. Some of the insulators are ivory. The maker is not known.

1011e * A view of the wiring under the base of the cable key:(60KB)


1012 SIEMENS BROTHERS CABLE KEY:(29KB) This massive cable key has its entire mechanism mounted on high columns above the base because of the high voltages which were often necessary in order to transmit messages through the very long cables. It measures 6-1/4"long by 4-1/2"wide by 5" high. The base is stamped Siemens Brothers & Co. The unusual triangular levers are used to hold the contacts in the closed position.


1014 * ELLIOTT BROTHERS CABLE KEY:(20KB) Large and massive cable key similar to 1012 with the high voltage columns but labelled Elliott Brothers and with brass handled shorting cams.>K5VT


1015 UNUSUAL ROCKER-TYPE BRITISH CABLE KEY: This is a very unusual cable key that uses a rocker-type mechanism. Pressing the left knob puts a positive voltage on the cable and pushing the right knob puts a negative voltage on the cable. There is no maker's name on the key but the hardware strongly suggests that it is British.


1016 * Ted Huston's CABLE DISCHARGE KEY:(14KB) This large key was used to discharge the capacitances on the long submarine cables in order to permit measurements. The high columns isolate the high voltages on the mechanism from the base. It is in the Ted Huston collection.


1019 * CABLE KEY LITERATURE SHOWING/DESCRIBING ABOVE KEYS:(80KB) This page shows some of the keys (shown above) which were used for submarine telegraph signalling and testing on the Washington to Alaska Military Cable and Telegraph System.


1020 * VERY EARLY AND UNUSUAL STRAIGHT KEY:(15KB) Heavy long oval brass base with round hole in the middle. steel lever. Extremely unusual round brass bar under steel lever runs between left and right upright pivot posts. Shorting lever under this bar is stamped WESTERN ELECTRIC CO.

1025 * VERY EARLY STRAIGHT KEY: Old all-brass key has a straight 1/4X1/4 inch brass lever bent down for an early-style knob. Wooden base with cotton-covered wires embedded in channels on the underside. The spring has a long gentle taper like Clapp-Eastham "Boston" key which it slightly resembles.


1026 * VERY EARLY STRAIGHT KEY & SOUNDER:(32KB) Key like #1025 with matching sounder.


1050 BEARINGLESS ''STEINER'' KEY: (20KB) The Steiner key is a very small key which is characterized by having no trunnion or bearings. The lever is supported only by a spring and knife edge. This one has a brass base which is stamped W.E.Co. New York. Pat'd Dec.21,1880. Mounted on newer wooden base.


1054 ''RESTORED'' STEINER KEY: (17KB) This is a small Steiner Key which has had its long legs cut off so it could be mounted on a metal base. The key has been chrome plated and the insulators have been replaced with white plastic material. The shorting lever knob has been replaced with a machined knob. I personally prefer to leave these keys in the as-found condition with perhaps a light cleaning to remove dirt.

1054a Another view of the ''RESTORED'' Steiner Key: (17KB)


1055 STEINER KEY: (28KB) This is a small Steiner Key whose design is characterized by having no trunnion and the lever supported only by a spring and knife edge. Brass base stamped W.E.Co. New York. Pat'd Dec.21,1880. This one has been mounted on a newer marble base.


1057 * STEINER KEY WITH UNUSUAL WESTERN ELECTRIC SOUNDER:(15KB) This Steiner Key was used with this very unusual Western Electric Sounder. The key has a brass base stamped W.E.Co. New York. Pat'd Dec.21,1880. The sounder has an unusual round anvil. I believe that this is a transitional design between the Western Electric rectangular frame sounders and the Western Electric all round frame sounders.

1057b * Closer view of the Round-Anvil Western Electric Sounder:(12KB)

1062 * PRIVATE-LINE CAST-BASE KOB WITH STEINER KEY:(35KB) This KOB has a Steiner Key and sounder cast into it's base. Private-Line KOB's were designed to be used on ''private telegraph lines'' in homes and businesses. They were made on cast iron bases which were often decorated with flowers and designs to better integrate into a home or business environment.


1067 EXCEPTIONALLY UNUSUAL STEINER KEY AND STRANGE AND COMPLEX RELAY ON WOODEN BASE, KOB:(40KB) This instrument was probably made and used by Western Electric since they were the most frequent users of Steiner keys. Its base was covered with mud indicating that it was immersed in a flood at some time. Removal of some mud revealed that the base and key were painted black while the relay was nickel plated brass.

The Steiner key is the only one if its kind that I have ever seen. It has a rectangular frame over the lever. This rectangular frame converts the normally-open contacts of the Steiner key into normally-closed contacts. All of the Steiner keys that I have seen are configured like the one on the Private-Line KOB and other Steiner keys shown above and have normally open contacts and no rectangular frame. I believe that the closed-circuit feature of this Steiner key was probably found to be necessary to work with the complex relay system to produce some sort of duplex operation.

The most unusual feature of this instrument is the extremely complex relay mounted on its wooden base. It was probably used in some kind of duplex circuit. Duplex circuits often employed complex relays in an attempt to send two signals on the same line and this is certainly a very complex relay. It has a set of single-pole double-throw contacts on top that move back and forth when BOTH of the coils are energized simultaneously. It has another set of single-pole double-throw contacts located toward the key that move from side to side when one OR the other coil is activated or when there is an imbalance in the pull exerted by the two coils. This is generally called a polar relay configuration in that the contact remains in its last position untill pulled over by the other coil. It is also clear that a box, probably made of wood, was mounted on the four pins that stick up around the relay. The exposed coils that could be easily damaged also suggest that the box was used to protect them and perhaps to keep people from trying to adjust the very delicate mechanism. Close views of the underside of the base show that the wiring was changed probably several times in what must have been an attempt to explore different circuit configurations.

1080 PUMP HANDLE KEY (The "Twentieth Century Key"):(48KB) Serial #386. All brass key with hanging wooden lever shaped like a pump handle, mounted on very heavy cast iron base. Wooden lever is pushed left to make contact. This key was designed to help overcome "Telegrapher's Paralysis" which we now call "Carpal Tunnel Syndrome". A small knob on the front of the key acts as the shorting switch. Key stamped "Made by Foote Pierson & Co. New York. Pat Applied For."
1082 PUMP HANDLE KEY:1082 ("The Twentieth Century Key").As above.Serial #1067. (Traded to K5VT).


1125 * MODERN SWEDISH ERICSSON-STYLE KEY:(21KB) A modern version of the lovely Ericsson keys shown below. (This key is the same as number 5050.)


1200 LARGE EARLY SWEDISH ERICSSON-STYLE KEY:(15KB) This is the classic early Swedish land-line key made from the 1870s well into the 20th Century. The key has a very long lever and a crisp 'feel'. Operators were trained to sit in front of the operating table with their upper arm straight down and their lower arm pointing straight ahead. Their seat height was adjusted so their arms made a right angle with each other. Their lower arm was thus parallel with the operating table. They were taught to grasp the key knob firmly with thumb and forefingers and to use ONLY up and down whole-arm movements to operate the key. You can see the cuts in the wooden base which were used to allow the wires to come up to the key connectors from the operating table. This is my all-time favorite key to own and to operate on the air.

1200b Another View of the Swedish Key:(17KB)


1215 SWEDISH ERICSSON-STYLE KEY: (49KB) Very large old all-brass key on a wooden base with very long lever and beautiful brass hardware and switch block. Made in 1880's by ERICSSON or KUNGLIGA TELEGRAFUERKET (The Royal Telegraph Administration) at their NYNASHAMN factory S. of Stockholm.


1217 SWEDISH ERICSSON-STYLE KEY: (49KB) Same as above but plated brass.


1219 SWEDISH ERICSSON KEY: (45KB) Like 1215 but smaller and perhaps older.
1221 * SWEDISH ERICSSON KEY: More modern version of above. Circa 1960s.
1222 * SWEDISH/NATO ERICSSON-STYLE KEY: Long 7" lever on brown base. Circa 1960s.


{1222} 5060 * {Duplicated from Wireless Keys section.} EARLY DANISH - GREAT NORTHERN TELEGRAPH WORKS KEY: This Danish key carries a label that reads: Great Northern Telegraph Works, Copenhagen, Denmark. No. 77773. It is not likely that 77773 of these keys were made since they do not show up very often. I think it is more likely that the manufacturer started with a high serial number. The picture was sent to me by another collector.

5060a * The Label on the Early Danish key:


{1223} 5070 * {Duplicated from Wireless Keys section.} LATER DANISH - GREAT NORTHERN TELEGRAPH WORKS KEY: This appears to be a later version of the Danish key above. This Danish key carries a label that reads: Great Northern Telegraph Works, Copenhagen, Denmark. No. 13779. Since it is not likely that 13779 of these keys were made it is more likely that the manufacturer started with a high serial number. Circa 1960s. The picture was sent to me by another collector.

1290 EARLY SWISS / ITALIAN LAND LINE KEY:(31KB) Heavy brass key with 1/2 X 5/16 X 4-1/2" straight lever. Adjustable pull-down spring beyond pivot. Doorknob shaped knob. Make & Break contacts. Huge adjusting screws. All parts and screw heads are numbered "12". 5-7/8 X 2-13/16" wooden base with recessed wiring. Greg Ulsamer, DL1BFE, reports that this kind of key was first made in the 1850's by a Mechanicus by the name of Kaufman in the town of Solothurn and later by the 'Eidgenoessische Telegraphenwerkstaette' which was the workshop of the (governmental) Swiss Telegraph Administration. Since many of these keys are found in Italy, it has previously been assumed that they were Italian.

1294 EARLY STYLE SWISS / ITALIAN LAND LINE KEY:(17KB) This medium sized brass key is typical of the early straight-lever Swiss/Italian land line keys (See above for an explanation of the confusion about the key's origin).

1294a A different view of the Swiss/Italian key:(18KB)


1295 * EARLY STYLE SWISS / ITALIAN LAND LINE KEY:(25KB) This medium sized brass key has the unique automatic shorting contacts that are typical of the early Swiss/Italian land line keys. Placing fingers on the knob pushes a plastic plate forward and unshorts the key readying it for transmission. Releasing the lever automatically places it in the receive mode. Greg Ulsamer reports that this key is called the ''Forchieri-key'' which is a family name from the Italian portion of Switzerland. It was first made by the workshops of the Swiss Telegraph Administration in the 1890s and used on the American type of Closed Circuit lines in Switzerland.

1295r * REPRODUCTION OF THE EARLY STYLE SWISS / ITALIAN LAND LINE KEY:(25KB) This key is a recent reproduction made in Italy in the 1990's.


1296 RECENT SWISS PRACTICE LAND LINE KEY:(28KB) This interesting key has its contacts supported on strips of thin spring metal. I am told that it was used by the Swiss military for practice... but the reason for placing the contacts on springs is unclear. The most likely explanation is that it reduces the noise of the contacts and it is less likely to annoy or confuse nearby student operators. The maker's name and location, E. Bischhausen, Bern is stamped on the frame under the lever.

1490 VERY UNUSUAL DELANEY PATENT KEY IN ROUND BOX USED FOR CONVEYING MORSE CODE OVER THE TELEPHONE:(51KB) This device consists of a J.H.BUNNELL "Triumph" key mounted inside an extremely well made 6" diam. circular wooden box. The metal label on the outside reads "DELANY PATENTS 1270398 1274520". There are absolutely NO electrical connections to the key which is entirely enclosed inside the box with the exception of the end of the lever and knob which extend out of the side of the box. The original 1917 patent sent to me by the well-known telegraph historian and key collector Roger Reinke shows that this key was placed underneath a candlestick telephone and that pressing the lever made a mechanical clicking sound against the base of the telephone which could be heard and read as morse code by the person on the other end of the telephone line. This seems very funny since there was already voice communication with the person on the other end of the line. Could it have been an early attempt at providing secure communications that could not have been listened in upon unless the eavesdropper knew the morse code? - But then, almost everyone knew the morse code in those days. ??
