Are you familiar with the air-brake and signal instructions as approvedby the M. C! B. and Master MechanicsAssociations? What other books on air-brake instruction have you studied ? A. Yes, sir. Also Westinghouse In-struction Book. Above is a diagram showing the capacityof the Hancock inspirator as tested in theapparatus shown. It will be seen that thewater-delivering range of the inspirator isremarkably wide. With 25 pounds press-ure when working full, the capacity of theinspirator was 1,000 gallons an hour. Asthe steam pressure was increased, the ca-pacity rose almost in a straight line Testing the Hancock Inspirator. The engraving shows a verycomplete and convenient testing room con-nected with the works of the Hancock In-spirator Company, Boston. The apparatviswas designed by Mr. Park, superintendentof the works, and has him to make 236 at the iiuiximum steam pressure of iSopounds to the .square inch, the capacity perhour was 1,400 gallons. The lower cur\ the action of the instrument whenthe feed was restricted to the lowest possi-ble limit. The study of that curve willshow that at one point the range betweenthe lowest and highest capacity variedabout 700 gallons per hour. «EAR lEPRHTMENT
