Morgan & Orr, in Philadelphia, was one of the largest press-makers in the world at the time as well as a major boiler maker. Their property extended most of the block between Callowhill and Noble Streets in Philadelphia, in the block between 12th and 13th (even with and two blocks behind the Convention Center); it's no longer there today. This model, which they called the Ajax, was capable of 150 strikes per minute and 200 tons' pressure.
