In accord nce with the provisions of lthe patent statutes, Ihave 'described the principle of operation of. my invention, together with the apparatus which I now consider to. represent the vbest embodiment thereof; but I desireto have it understood that the apparatus shownis only illustrative, and that the invention can be carried out by other means.

What l claim as new-and desire to secure bv Letters Patent of the United States, is

l. The combination with a stem turbine supplying exhaust steam to consumption devices, 'of a speed governor, a valve for admitting high pressure steam to the turbine, a valve admitting lhigh -pressure steam to the exhaust pipe, and a valve Jfor blowing 0E steam Jfrom 'said pipe, all three valves/ being controlled by the speed governor; f

Q. The combination with a steam turbine, supplying exhaust stearato consumption de- ,5 vices, of a speed governor, a valve. Jfor admitting high pressure steam to the turbine, a valve admitting high pressure steam to the exhaust pipe,` and a valve for blowing od steam from said pipe, all Vthree valves being G ,controlled by the speel governor, a device responsive to pressure changes in the exhaust v A A v g Asupplying exhaust steam 18 to open the blow-off valve 16130A relieve' Without vdisturbing the valve 3. The .Sys` and compen load onv the turbine or the demand. of the' on said pipe,

3. The combination 'with-a steam turbine..

vices, of a .valve admitting sumption devices increases, and for opening i the blow-o valve under opposite' condit1ons.

5. The combination with a steam turbine supplying exhaust steam to consumption devices, of a valve admitting high ressure steam to ,the exhaust pipe, a blow-olii' valve a speed governorior the turbine, a pressure 'responsive deviceiconnected with the. exhaust pipe, and operative connections between said valves andtli'e governorand pressure Fegulator whereby an increase o load on the turbine or a decrease in the demand of the consumption devices will cause an opening of the blow-oli' valve, and opposite conditions an opening of the high pressure steam valve.

In witness whereof, I my hand this second day of September, 1914.
