ssure in adirection opposite to that acting upon the impeller disk, whilethe chamber upcn the opposite side of the balancing disk is con-nected to the suction inlet, thus completely neutralizing {he un-balanced pressure on all of the wheels. As in the case of single-stage blowers, the head-delivery char-acteristic can be varied considerably to meet different require-ments. Generally where compressed air is used in tools, a fairlyconstant pressure over a wide range of delivery is desired. Thecappcities in such cases range between 2,000 and 10.000 cu. ft.per nun., and the pressures from 75 to 120 lb. per sq. in. Less than 2,000 cu. ft. per min, is usually not practicable. The largermachines for these pressures or machines which must run atmotor speeds, are usually built in two sections, with separateshafts and housings, the speeds available with electric motors ofthese sizes requiring either a compressor with a large numberof stages and several housings, or the use of a step-up gear, by

The use of acids for this i)urpose is not entirely satis-factory and this method is also dangerous for the workmen. Tlie matter of cleaning has assumed increased importancewith the general advent of the steel passenger car, and wheresand blasting has been adopted it seems to have been productiveof remarkably good results.

Ingersoll-Rand Low Pressure Type Turbo-Blower generally employed for the classes of service mentioned andin the case of the I-R turbo-blower, the high operative speedpermits direct coupling to the motor. This motor-drivenblower maintains constant pressure while delivering any volume from zero to maximum demand and proportionatelyvarying the electrical horsepower input. These blowers embody the four bearing construction fea-tured in all turbo machines of this make. The casing is hori-zontally split for ease in installation and subsequent inspec-tion. The assembled casing is doweled and bolted to a heavysub-base which ordinarily serves for both blower and drivingelement. The I-R machine occupies small floor space and itslack of vibration in operation obviates the necessity forfoundation bolting. The impeller is of the enclosed doubleflow type, which is claimed to secure the highest efficiency.The wheel is machined from a solid, special steel forging.The vanes and covers are of pressed s
