Railway and Locomotive Engineering . p as an awful of waste ofcnergv. utilizing as it does only about1/10 of the heat of the fuel consumed ingenerating the steam used. Loss of en-ergy is by no means confined to the steamengine. In a paper read before theAcademy of Science cf Washington byProfessor Langley he demonstrated thatin the argand burner only 24 parts ofenergy out of every 1,000 arc utilized aslight—a loss about four times greaterthan the steam engine. Some months ago we printed a descrip-tion of the Goff system of electro-pneu-matic brakes for steam road service thatwas particularly adaptable to freight carsand at the present time we have a cutshowing a brake system for street cars,that mav also be used in steam railroad reservoirs at all times, regardless of re-peated applications of the brakes, whichinsures efficiency and safety, particularlyon mountain grades or in congested trafficcenters. Full combined capacity of thecar reservoir, brake pipe and air com-pressor may be delivered to the brake cyl-. kesi;k\oik .\.\d goff brakk-. service. The illustration shows the com-plete system for a car, and it will beobserved that no triple valves are re-quired, the brake however being auto-matic. The inventor claims, and a studyof the description will show, that thebrakes will positively apply whenever themotorman so desires, or in all cases ofaccident or failure, such as broken wires,failure of current, battery or generatorfrom any cause. The brake may be ap-plied or released in full, or graduated onor off with any desired pressure. .Acci-dental of the air hose or brakepipe does not interfere with the applica-tion or the release of brakes. The max-imum air pressure is maintained in the inder, guaranteeing a high pressure emer-gency brake. A glance at the cut will show that thisdevice is so simple as to require nolengthy description, an ordinarj electro-magnet being used to control the flow ofcompressed air f
