It is thought that this item may have been made for use at the Ballarat School of Mines. The use is unknown. At one time it was thought to have something to do with lens-making, but this is no longer thought to be the case. A photograph of this item has the catalogue number 01002.A mechanism made of cast brass mounted onto a second hand timber base board. Two horizontal coaxial shafts, each ending with a hemispherical cup, facing each other. The right hand shaft is fitted with a crank handle. The diameter of the two brass domes is 6 cm. The space between the two brass domes from spindle to spindle is 7 cm. Only one dome turns, the one attached to the handle. Brass plate on second handtimber base board "J. Sturrock, Dundee. Patentee.

A hacksaw is a fine-tooth saw with a blade held under tension by a frame. It is used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, and pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. On the push stroke, the arch flexes slightly, decreasing the tension on the blade.Steel frame for blade. adjustment lever in handle.Dimpled feature on curved sectionhacksaw, tool, ballarat school of mines, trade, cutting, metal, plastics

A mining safety cage was used in a mine lift. It was fitted with mechanisms to prevent the cage from dropping if the lifting rope broke. In the 1870s in Victoria, deaths and injuries from falling cages in vertical shafts of gold mines were a major problem. The inventor of this safety cage was Robert Allan, a machinery maker of Creswick Rd, Ballarat. He said his cage featured a ‘dissolving’ fulcrum. Others called it an eccentric (off centre) system. Note the pair of clutch levers designed to grab the side guides if tension ceases in the suspending rope from the poppet head pulley. Also, the hinged ‘lids’; designed to protect miners trapped in a braked cage from falling rope, and to enable rescue of the miners. This model was presented to The Ballarat School of Mines Council in November 1876. This model was shown at the Smeaton Show in November 1874, Ballarat School of Mines Museum from 1876, and examined by the 1879 Victorian Board of Inquiry (Pg 15 of FedUni Catalogue 3437) From the Argus of 13 November 1874: At Smeaton Show, Robert Allan of Ballarat won 1st prize for a Model of a Mining Cage, a Butter working machine, a Cheese press and a Curd Mill. By 1878 an Allan Safety-Cage was in operation in the Number 6 shaft of the Band and Albion Consols mine in Ballarat. This cage was judged the best inspected by the Victorian Board of Inquiry by 1879, p. 39.Mining was a big industry in Ballarat in the late 1800s and a lot of deaths were recorded because of mining accidents, the development of the mining safety cage brake limited the deaths and injuries from falling cages in vertical shafts. The model also has links to the Ballarat School of Mines, being presented to the council in 1876. Ballarat School of Mines is the oldest Technical School in Australia and is a predecessor of Federation University. The model is significant to Ballarat's mining history.Model of a mine safety cafe. A grey painted wooden frame with metal model of cage and safety brake system. When tension ceases in rope a pair of crutch levers grab strongly onto the wooden guide strips which run down the sides of a vertical shaft. This safety cage was discussed in "Safety Mining Cages.

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
