170 EXTREMELY EARLY GERMAN LAND-LINE CAMELBACK KEY:(14KB) This is one of the very earliest German Camelback keys that I have ever seen. I believe that it dates to the early 1850's based on my research in the Siemens and Deutches Museum Archives in Munich. I believe that the number stamped on the side of the key is either a part number or the date in which it was placed in service. I have included several different views of the key.

181 EARLY GERMAN BRASS LEVER CAMELBACK PRACTICE KEY:(18KB) Small 3-3/4" brass lever with camelback curve and upward pointing end leading directly into knob. An early flat spring provides the tension. This design is typical of most of the early Prussian land-line keys. These keys were used with early German telegraph practice sets as shown below which are the German equivalent of the American Bunnell Camelback key and sounder practice sets.
182 * EARLY GERMAN TELEGRAPH SET: KEY, REGISTER, RELAY:(13KB) This simple practice set is the German equivalent of the American Bunnell Camelback key and sounder practice sets. The simply-made key follows the classic lines of the earliest Prussian Camelback keys. The register is also of very simple design. The paper tape is simply pulled through the register by hand. The relay, although simply made, is patterned after the earliest Prussian relays.
182a * ANOTHER EARLY GERMAN PRACTICE REGISTER:(23KB)
This is another variant of the very simple, hand-operated design.
182b CATALOG ILLUSTRATION OF COMPLETE EARLY GERMAN PRACTICE SET:(22KB)
This illustration shows a box containing a complete German practice set consisting of 2 glass batteries, 2 keys, 2 registers, and 2 rolls of wire. The catalog was published in 1910/1911 by Edmund Prandstatter of Munich, Germany. It is interesting to note that registers were still being produced and sold at this late date in Germany while Americans had abandonned registers in favor of copying code by ear from sounders around the 1860's. It is also interesting to note that there are NO sounders offered for sale anywhere in the catalog !!
182c CATALOG ILLUSTRATION OF ANOTHER GERMAN PRACTICE SET:(15KB)
This practice set from the above catalog included a more complex spring-driven register which pulled the paper tape automatically.

183 VERY EARLY GERMAN CAST LEVER CAMELBACK KEY:(25KB) Massive 4-3/4" long cast lever with the classical Prussian camelback shape. An early flat spring provides the tension. Normally open contacts only.
185 UNUSUAL EARLY GERMAN CAMELBACK KEY:(15KB) Small 4-1/4"Camelback lever with unusual upward pointing end leading directly into knob. Key is pivoted on far end and has coil spring. Black 3-1/2x2-1/2 base stamped: E.ZIMMERMAN, LEIPZIG. This key was sold for use in scientific experiments as well as for telegraph.
0187 EARLY GERMAN 'SIEMENS' KEY, REGISTER, & GALVANOMETER (KROB) SET:(16KB) This set is a typical example of an early European land-line telegraph system consisting of a straight-lever German key, an ink writing register, and a galvanometer for measuring the condition of the line. A roll of paper tape on which the dots and dashes were written (in ink) is stored in the drawer under the register. This set was manufactured by Siemens.

0188 EARLY FRENCH KEY, REGISTER, & GALVANOMETER (KROB) SET:(21KB)
This set is a typical example of the early European land-line telegraph systems which consisted of a straight-lever German-design key, an ink writing register, and a galvanometer for measuring the condition of the line. It is called a ''KROB'' set which stands for: Key and Register on Base. A roll of paper tape on which the dots and dashes were written (in ink) is stored in the drawer under the register. This set is stamped with the French manufacturer's name but the design of the key and register are clearly Siemens. The name stamped on the set reads: Societe Industrielle des Telephones, 25 Rue du 4 Septembre, Paris. I believe that the set was probably originally manufactured or certaily licensed by Siemens.
NOTE the interesting telegraph key which has the characteristic German Siemens spring-mounted lower contacts AND surprisingly, it has two tension springs. One spring is mounted in front of the trunnion and one spring is mounted in back of the trunnion. It is unclear why the spring in back of the trunnion was needed.
The only other two-spring key that I have been able to find is listed in the Spark and Radio keys' and the 'German Military keys' sections of this museum. The following views of this set allow you to see all of the important details.

This set is a typical example of a land-line telegraph system consisting of a straight-lever German key, an ink writing register, and a galvanometer for measuring the condition of the line. This one is somewhat later than number 0187 and the black meters were probably added later than it's first date of manufacture. It was manufactured by H. Wetzer, Pfronten Bayern.

190 LARGE WESTERN UNION TRANSATLANTIC CABLE KEY:(51KB) Two large old brass levers mounted on a 4-1/2x6" black rubber base. The left lever was used to send dots. Pressing it drove the cable voltage positive. The right lever was used to send dashes and drove the cable negative. Since the cable was thousands of miles long, it acted as a huge capacitor and the full plus-to-minus voltage was necessary to help it discharge. The messages were recorded on a moving paper strip and it took skill to visually tell the difference between dots & dashes.

192 LARGE ELLIOTT BROTHERS TRANSATLANTIC CABLE KEY:(51KB)This is a very fine example of an early submarine cable key. It has survived in very good condition and shows a plethora of adjustments that allow it to be set to the exact tension and spacing desired by an operator. The left lever was used to send dots. Pressing it drove the cable voltage positive. The right lever was used to send dashes and drove the cable negative. Since the cable was thousands of miles long, it acted as a huge capacitor and the full plus-to-minus voltage was necessary to help it discharge. The cable messages were usually recorded on a moving paper strip and it took skill to visually tell the difference between dots & dashes. This key, however, was used with the super-sensitive relay shown below instead of the typical paper tape recorder.

193 SUPER-SENSITIVE POLAR RELAY USED IN SUBMARINE TELEGRAPH CABLE LINES:(70KB)The electrical signals on a submarine telegraph cable were usually recorded on a moving paper tape and then translated into letters by eye. This relay has the extremely high resistance of 506 Ohms, making it sensitive enough to detect the very small voltage changes in a submarine cable. In addition, it has numerous very fine adjustments that allow it to be set to react to very weak signals such as thouse received over very long cables. There is some engraved writing on the top of the relay but I have been unable to read it because it is not engraved deeply enough into the metal. This relay was located along with the Elliott Brothers Submarine Telegraph Cable Key shown above and was probably also made by Elliott Brothers.

212 COMPLETE PORTABLE WESTERN UNION TELEGRAPH OFFICE:(17KB) This is a complete portable 1870's Telegraph office. It is contained in a special box which serves as a desk and which can be attached to a telegraph pole. It was carried in a railroad car and used for emergency communications along the railroad line. This is a very interesting set so I have included many different views of it and it's components. Several views are very similar to each other but have slightly different color balance. As you can see, the set can be attached to any convenient telegraph pole using a chain attached to the back of the cabinet. It can be electrically hooked into any telegraph line using the special connector called a 'Wrecking Clamp'. A blueprint shows the wiring of many of the telegraph poles along the railroad line so the telegraph operator can know which line to tap into. The following views and descriptions should explain the operation of this unusual set...
Very similar portable telegraph offices were carried in Fire Chiefs' buggies in major city fire departments to allow communications during major fires. A pole-mounted tent was often used to protect the equipment and telegrapher from the elements in bad weather.

232 EXTREMELY UNUSUAL STRAIGHT LEVER FLAT TERMINAL LEWIS KEY:(16KB) This is the strangest Lewis Key that I have ever seen. The lever is nearly straight which is unusual for Lewis keys but the most unusual aspect of the key is the three flat-topped terminals which, as you can see from the underside view connect to the normally open, normally closed, and frame of the key. There is no way to connect wires to these terminals directly so I can only assume that the key was slid into some sort of spring loaded contact assembly. I have included several different views of the key.

280 * VERY EARLY CHARLES WILLIAMS (Boston) KEY & SOUNDER:(36KB) Early brass straight lever key and extremely early sounder mounted on a wooden base. Sounder design suggests that it is circa 1850's. Traded to W2PM
281 VERY EARLY AND UNUSUAL 'PUTT' NON-ELECTRIC PRACTICE SET:(36KB)This set is very similar to the Charles Williams Set listed as number 280. It has, however, no electric mechanism. Pressing down on the key operates a long metal bar hidden under the base which, in turn, pulls down the sounder. Each time the key is pressed, therefore, the sounder makes a clicking sound. The set was used for code practice without the need for batteries. The wooden base is stamped: PAT'D MAY 31.70 D.W.PUTT & Co. WELLSVILLE.O
285 VERY EARLY JAMES CLARK (Philadelphia) CAMELBACK KEY & BOX SOUNDER:(35KB) Very unusual camelback key with pull-down spring at far end and Prussian-like upswept lever mounted on wooden base with early wooden box sounder. Circa 1850s.

Key mechanically connected to a bar which strikes an anvil inside the resonator making clicking sounds for practicing sending & receiving. Marked:SOUNDER D'EXERCICE,Alban La FON,EVEREUX. Signed R.Guillet,PTT twice.
315 BUNNELL NON-ELECTRIC PRACTICE SET:(39KB) Brass, horizontally-mounted sounder lever with small telegraph key knob attached directly to it. It was used to provide practice clicking sounds for people learning the Morse code without the need for batteries and wiring. Japanned, pinstriped frame on wooden base. Original box & stamps.
325 BUNNELL ARTICULATED NON-ELECTRIC PRACTICE SET:(15KB) Interesting combination of a brass sounder and telegraph key with a mechanical connection whereby pressing the key causes the sounder to move downward to make a click. It was used to provide practice sounds for people learning the Morse code without the need for batteries and wiring.
325a EARLY BUNNELL LOGO STAMPED INTO BASE:(22KB)
405 KNUDSEN MORSE REGISTER:(62KB) Made by Cornelius Knudsen in Denmark. - circa 1850 Before it was discovered that the Morse code could be copied by ear, "Registers" were used to print the characters on a paper tape for later transcription. These spring powered Registers continued to be used because they were thought to be more reliable than sound copy and because they made a permanent record. This is a very early brass register with an unusual armiture which presses the paper tape up against the (missing) pen to mark dots or dashes on the tape in ink. It has a key wound mechanism (with key) which runs constantly.
650 * EARLY L.G.TILLOTSON SOUNDER:(17KB)
Early all brass frame with brass armiture stamped L.G.Tillotson, 8 Dey St. New York with steel trunnion crimped into brass armiture. Horizontal adjusting spring. Wooden base. Notice the box-like anvil. It is similar to the Williams Sounder (Number 280) and the Putt practice set sounder (Number 281) seen above although those anvils were mounted on a single upright post.

685 * VERY EARLY L.G.TILLOTSON SOUNDER: Very early all brass frame with
brass armiture stamped L.G.Tillotson, 26 Dey St. New York with steel
trunnion crimped into brass armiture. Horizontal adjusting spring.
690 UNUSUAL VERY EARLY ROUND L. G. TILLOTSON SOUNDER:(29KB) Ornate brass design with brass armiture stamped L.G.Tillotson, 8 Dey St. New York, with steel trunnion crimped into brass. Horizontal adjusting spring. All mounted on ROUND plated brass base.
691 * VERY EARLY TILLOTSON SOUNDER: Medium size, all-brass sounder in
excellent condition. Armiture is stamped "L.G.TILLOTSON & Co. 5&7 Dey
St. New York." and "Pat'd Feb 16, 1875". Base is also stamped TILLOTSON
and same address.
692 * VERY EARLY TILLOTSON SOUNDER: Similar to above but smaller. Armiture
patent reads "Patent July 1874. No address on base. >Traded out.
693 * UNUSUAL TRANSITIONAL SOUNDER WITH VERTICAL AND HORIZONTAL SPRINGS:(17KB) This is an interesting sounder which has parts for both horizontal and vertical springs. Although the Anvil is broken off, you can see where the horizontal spring adjusting screw was mounted. You can also see how the vertical spring was mounted. The transition from horizontal springs to vertical springs is generally believed to signal a major shift in sounder design strategy and this sounder appears to incorporate both designs.

694 * VERY EARLY GREELEY SOUNDER: All plated. E. S.GREELEY & CO.
5 & 7 Dey St. New York.
740 VERY UNUSUAL SOUNDER-ACTUATOR?:(8KB) This extremely unusual sounder/Actuator was found at an abandonned railroad station in the far west. It is of cast iron construction and looks very early. The sounder mechanism has an added long lever which allows it to act as an actuator to perhaps activate another mechanical mechanism.
800 * EXTREMELY EARLY TILLOTSON RELAY:(33KB) This extremely early L.C. Tillotson relay exhibits the early spring-through-the-post design along with the post-mounted contacts. These features were abandonned early in the design of relays. It is stamped L.C.T. & CO. 6 DEY ST. NY. 60 ohms. Circa 1850's. (Traded to John Casale - W2NI.)
945 VERY EARLY TELEGRAPH PLUG-BOARD:(33KB) This board was used to connect office telegraph instruments to 4 telegraph lines. Brass plugs with insulated handles shorted the blocks together and made the connections.
