Historical information

Samuel Cross worked for the Hamilton Waterworks Trust and his invention relates to a box joint in two sections and is particularly useful for repairing a pipe containing fluid under either high or low pressure in which a leak, blow out, or burst occurs. Samuel Cross' invention is mentioned in the minutes of the Hamilton Waterworks Trust, copied pages can be found in the supplementary files.


Cross' invention helped to prevent water loss whilst a pipe was being repaired. Hamilton Waterworks Trust was an early predecessor to Glenelg Water which later merged with Portland Coast Water and South West Water to form Wannon Water. The patent is significant because the invention was revolutionary for the early Victorian 20th century engineering, and it is still being used today.
