The air pump is the regularConover pattern, vertical, single-acting, and is made amply largefor the slowest revolutions required to give the proper amountof water through the circulating pump. The pumps are arrangedto vary the speed to give the proper amount of circulating waterthrough the surface condenser at all times, the air pump takingcare of itself. The air pump, excepting for the slight difference infriction, requires practically the same power to operate it withoutreference to the speed.

As the same water and air are delivered ineach case, a faster speed merely delivers a smaller quantity at eachstroke, and proportionately reduces the mean effective arrangement, therefore, gives all the advantages of separate air and circulating pumps in a combined machine, with less worl The Jackson & Sharp Company, of Wilmington, Del., has justcompleted a number of long suburban cars for the Rochester &.
