The cylinder is secured to the topcross members of tiie press frame by four bolts extending up-ward between the channels. A three-way valve with suit-able piping provides for the admission of air to either sideof the piston and for the exhaust of the air to the atmos-phere. The space between the side frames is 10 ft. 6 in. and thehead room above the bedplate is 7 ft. 9 in., providing ampleroom for the operators and permitting the use of a sledge ifnecessary.
