An immense hydraulic riveting plant the largest ever made has been built in London for an engineering company in Holland, and is to be employed on marine boilers. The riveter has a gap 12 feet deep, closes its jaws with a power of 200 tons, and is capable of closing rivets up to 3$ inches in diameter. A traveling travel-ing crane, 50 feet high, is designed to raise and manipulate a boiler weighing anything up to 50 tons. The crane is operated by two engines, steam for which and the powerful pumps giving hydraulic power for the riveter's great accumulator is supplied by two steel boilers, each capable of doing duty equal to about 1:30 indicated horse power.
