The Workshop.

RIVETING BY HYDRAULIC POWER _ The Engineer illustrates an hydraulic riveting machine, which is a representative specimen of the system which is now coming into extensive use in England. It can deal with a row of rivets about six feet six inches long, and the compressing strain is about eighty tons per rivet when the machine is doing its maximum, which can be reduced to twenty tons by taking weights off the accumulator. This is by far the most powerful riveting machine ever made. One at Jarrow, England, can take in a seam eleven feet lon°-, but the strain per rivet is only thu-ty°tons. Ine great range, however, of the Jarrow machine enables a marine boiler shell to be riveted straight off, without stopping to turn it end for end. °
