Probably acquired for use in Telegraphy courses run at the Ballarat SChool of Mines between 1875 and 1893. Telegraph relays amplified electrical signals in a telegraph line. Telegraph messages traveled as a series of electrical pulses through a wire from a transmitter to a receiver. Short pulses made a dot, slightly longer pulses a dash. The pulses faded in strength as they traveled through the wire, to the point where the incoming signal was too weak to directly operate a receiving sounder or register. A relay detected a weak signal and used a battery to strengthen the signal so that the receiver would operate. This relay was made by the firm of Charles T. and John N. Chester, two brothers who successfully partnered in New York City. Charles (1826-1880) founded the firm and provided the expert telegraphy knowledge while John (1820-1871) kept the books and managed the business operations.(http://americanhistory.si.edu/collections/search/object/nmah_706518, accessed 25/01/2018)Electromagnetic relay device used in telegraphy. The working parts mounted on a brass plate, attached to a wood base. Equipped with four terminal posts. Adjustable contactor mechanism. This electromagnetic Relay Device was used in Telegraphy at the Ballarat School of Mines. After a special meeting of the Ballarat SChool of Mines Council in 1874, a decision was made to offer instruction in Telegraphy, a subject not directly related to mining. Telegraphy was taught by W.P. Bechervaise, postmaster at Ballarat. On 07 October 1874 the Ballarat Courier correspondent reprted on Telegraphic training: "... these classes ... are a snare and a delusion, as there is scarcely the remotest chance of obtaining employment when the examination has been passed."scientific instrument, telegraph relayer, telegraphy relay device, telegraphy

The Postmaster-General's Department (P.M.G.) of Australia was created in 1901 with Federation taking control over all six Colonies (States) Postal and Telegraphic services within Australia to form the national Postal and Telegraphic services within Australia. The Department was administered by the Postmaster-General. This manual was produced as a syllabus of training for Army Personnel units in P.M.G's Department schools.In war times the postal organisation was a vital link between the services, the community and overseas centres. The Postmaster-General's Department co-operated with service departments in the installation and operation of radio, telephone and telegraph systems. Its laboratories also designed, developed and manufactured vital defence equipment. This item reflects that contribution and history.A 31 pp buff colored book with orange cloth binding.

A telegraph key or Morse key is a specialised electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Keys are used in all forms of electrical telegraph systems, including landline (also called wire) telegraphy and radio (also called wireless) telegraphy. An operator uses the telegraph key to send electrical pulses of two different lengths: short pulses, called dots or dits, and longer pulses, called dashes or dahs. These pulses encode the letters and other characters that spell out the message.Metal device with black knob mounted on a wooden base. A plaque with printed text is also attached to the base.Printed: GIVE A SERIES OF DASHES INSTEAD / OF A STEADY EXPOSURE WHEN CALL- / ING FOR LIGHT, OR SHOWING LIGHT. / USE THE PLUG IN No. 1 / SOCKET AS LONG AS THE / LIGHT IS GOOD ENOUGH. / THEN CHANGE TO No. 2 THIS WILL / LENGTHEN THE LIFE OF BOTH BULB / AND BATTERY.morse code, communication, telegraph key, messages, pulses

Galvanometers are an instrument used for detecting and measuring electric current. They had a magnetic needle moved by the magnetic field produced by coils carrying the current to be measured, and the earth's field had to be taken into consideration. They were used to detect current in either direction in telegraphy systems, and to test equipment.Post Office Galvonometer.
