The International Exhibition: Spencer's patent magnetic purifying-filter, 1862. Creator: Unknown

The International Exhibition: Spencer's patent magnetic purifying-filter, 1862. This filter has secured for its inventor, Mr. Spencer...one of the prize medals of the International Exhibition of 1862. The magnetic filter is the only one known which effects a chemical purification of water. Indeed, it has been said by one of our scientific authorities that "miasmetic or unwholesome water with the magnetic filter is impossible." Those fitted up for domestic use comprise three compartments, separated from each other by perforated plates. The upper open compartment is for the water to be purified; the middle one contains the proto-carbide of iron, which is the magnetic purifying medium; the lower one is for the purified water to be drawn off at the tap as required. It is affirmed that...these filters never require cleansing or renovation, but will constantly give forth colourless and odourless water, free from gaseous or organic impurity, and which will remain free from the growth of animalculae or vegetation. The protocarbide bears the closest affinity to the loadstone, or natural magnet, and its magnetic power is equally indestructible; whilst bulk for built, from its extreme purity, the artificial body exercises the more powerful agency'. From "Illustrated London News", 1862

EDITORS COMMENTS
This image showcases Spencer's patent magnetic purifying-filter, a groundbreaking invention that earned its creator, Mr. Spencer, one of the prestigious medals at the International Exhibition of 1862. The magnetic filter represented a significant advancement in water purification, as it was the only known filter capable of chemically cleansing water. According to scientific authorities, water treated with this filter became impossible to classify as miasmatic or unwholesome. The filter consisted of three compartments, each separated by perforated plates. The upper compartment held the water to be purified, while the middle one contained the proto-carbide of iron, the magnetic purifying medium. The lower compartment was designed for collecting the purified water, which could be drawn off at a tap as needed. The inventor claimed that these filters never required cleansing or renovation, and they would consistently produce colorless and odorless water free from gaseous or organic impurities. Moreover, the water would remain free from the growth of animalculae or vegetation. The proto-carbide in the filter bore a close resemblance to the lodestone or natural magnet, and its magnetic power was equally indestructible. Its extreme purity granted the artificial body a more potent magnetic agency. This filter represented a significant leap forward in water purification technology, offering a reliable solution for producing clean water for both domestic and potentially industrial use.
