Used to communicate with the local telephone exchange and for connection to other subscribers. The introduction of automatic exchanges saw the their demise. This phone was used in the family home of the donor at Caboolture (aboriginal for carpet snake) during the 1940s and 1950s.A magneto telephone for communication with a manual telephone exchange. The handle on the right hand side, which was turned to rotate the magneto to call the exchange - ask operator for a number and then to be connected. Telephone enclosed in a specially designed box for mounting on the wall. There was a bell on top which rang when the magneto ringer at the exchange was turned. Fitted with a carbon microphone mounted on the front of the box for the transmission of the spoken word and an electro- magnet. A receiver which hangs on the left hand side on a hook. The hook acts as the on and off switch to answer the call and to switch on the battery to provide power for the receiver and energize the transmitter. There is an angled ledge for writing any messages. There is no battery. The circuit for the phone is on the inside of the door to the interior of the phone. pHone is type CDA116 - PMG Registered - Ericsson.communication, telephonic

The Strowger switch is the first commercially successful electro-mechanical stepping switch telephone exchange system. It was developed by the Strowger Automatic Telephone Exchange Company founded in 1891 by Almon Brown Strowger. In 1912 Australia's first automatic telephone exchange was installed at Geelong. Victoria. The exchange equipment was Strowger Automatic telephone apparatus, manufactured by the Automatic Electric Company, Chicago USA. This is a useful research tool for the history of telephony.A 96 pp bound book with a dark brown cover.

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.

The Ericofon was the first commercially successful telephone which incorporated both handle and dial within a single unit. Manufactured by the Swedish company Ericsson, and available for lease from the Postmaster-General’s Department, the streamlined design has been praised for anticipating the cordless phone, and later mobile phone, by several decades. The ‘cobra’ design was formulated in the 1940s and manufactured in the 1950s; Australian cases were likely made in the L M Ericsson Broadmeadows factory. Although new thermoplastic technology allowed for a bolder aesthetic than traditional black Bakelite telephones, Ericofon sales accounted for only 4% of the market and it never enjoyed popularity with Australian subscribers. The design did, however, spark a conceptual shift whereby the telephone “was seen more as a consumer product than merely an extension of telephony” (Ericsson).Clear plastic telephone casing inside which are coloured electrical wires. Telephone has a broad base that contains the dial, mouthpiece and cord with cream plastic coated wall plug attached at rear. Handle tapers in a curve to a stylised squared earpiece.

W.B Withers wrote of Sutton: "In the realm of science Ballarat has become of world-wide fame through the inventions by Mr Henry Sutton, a native of the place. His skill and acquirements in electricity, telegraphy, telephony, photography and also in astronomical and microscopal studies have won for him a high position as a practical scientist, and the credit is the greater as he is a self-taught student … Mr Sutton, before he was fourteen years old, had read every book on science to be found in the library of the Ballarat Mechanics' Institute." The Ballarat School of Mines (SMB) was fortunate to have this genius appointed as the lecturer-in-charge of the new Electricity and Magnetism department from 23 April 1883. Although Henry Sutton submitted his resignation to the Council of SMB in October 1884 it was resolved that he be asked to reconsider, and Mr Sutton continued to teach at SMB until the end of 1886. He was a prominent member of the Camera Club, and many of the other SMB clubs. Sutton had an active and fertile brain, and was known for his inventions, especially his work on the telephone, telephane and carbon lamps. Sutton presented a vacuum pump, worked by water jet, for use in SMB Chemistry classes. His report of 1883 states: ‘A telephonic circuit has been laid down between the [SMB] engine-house and workshops, to be used for experimental purposes.’ Henry Sutton spent much thought on artificial flight, and made some interesting experimental studies with flying birds. The storage of electricty also attracted his attention, and, after much work and thought evolved the Sutton Secondary Battery. A paper on this battery was presented to the Royal Society, London, and was afterwards printed in the 'Transactions'. Henry Sutton is listed on the Federation University Honour Roll at https://www.federation.edu.au/curator/honour-roll/honourroll_sutton.shtmlA crude scientific instrument that measures amps, with a timber base and frame. Terminal posts and sliders contacts are positioned on top of the base, with flex attached. Henry Sutton lectured at the Ballarat School of Mines (SMB) in Electricty and Magnestism between 1883 and 1886. In 1883 Sutton reported: ‘…The class has been unfortunately situated, by having to wait for instruments of precision ordered from England, but which have not come to hand. The delay has caused us to start constructing instruments, which it is hoped will bear favourable comparison with those of older date.'ammeter, henry sutton, electrical, inventor, electricity and magnetism, sutton, scientific instruments
