Name/TitleEquipment: Corporal Coles Prosthetic Hand
About this objectIn 1842, while preparing a cannon for a celebratory firing in honour of the birth of the Duke of Cornwall, it exploded early and Corporal Coles lost his right hand and most of his left hand except the thumb. Governor Grey organised the making of a prosthetic hand by Surgeon Dentist Robert Norman, paid out of his own pocket. A silver plaque is attached to the hand. The hand was used until John Coles died in 1886. The hand is made out of whalebone, has four fingers and is operated using strings and pulleys. The fingers are flexed by contracting the strings which are connected to a ring on the remaining thumb.
Corporal John Coles, Miner and Sapper, was injured in a parade ground accident. In 1842, while preparing for the second firing of a cannon in a celebratory salute in honour of the birth of the Duke of Cornwall, the gunpowder exploded and Corporal Coles lost the fingers of his right hand except the thumb, and the top of his left hand forefinger. Colonial Surgeon, James Nash, performed minimal amputation of the damaged areas as Corporal Coles was concerned to not have his entire hand amputated.
Robert Hasting Norman, Surgeon Dentist, arrived in Adelaide in 1844, establishing Adelaide and the colony’s first dental practice in Wright Street. A learned gentleman, Robert Norman also carved objects from ivory and bone, exploring mechanical applications with his craft. Governor Grey sponsored the construction of a prosthetic hand by Robert Norman for John Coles. An engraved silver plaque, "Presented by His Excellency Governor Grey. Robert Norman "Inventor", is attached to the prosthetic hand. John Coles used the prosthetic hand until his death 1886.
The prosthetic hand was reported as being made form “sea-cow”, intricately carved to copy details of fingers and nails. The catgut pulleys were interlinked with small spools, carefully worked into the knuckle joints, manoeuvred by the limited lateral mobility of the only remaining digit, the right thumb, over which a ring was placed which attached to the pulleys. The prosthetic hand was described as ‘beautiful in its mechanism and accurate in its working that Corporal Coles could pick up a button or a sixpence with pleasing facility’.
