, Beit known thatl, GEORGE NEWTON. JONES, of Chicago,.in the county of (IiookandA State ofA Illinois, have invented a,` new,and useful Improvement. in' a Whistle forHSteam-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable 'others skilled inthe art to 4make and usethe same, reference being hadto the ccompanyin'gdrawing'formingpart of this specifica- "My invention relatesjto steam-whistles, to `give the aiarmat high or low water, in the boiler of an engine.

The drawing' represents a boiler, with 'a float, B,

. rising' and falling .therein witlifthe water. l

lglance the relative location of my. improvements with respect tothe other'devices employed in connection witlifsteamboilers.

The mode of operation is as follows:

L The? steam presses constantly against the slide-valvel 0,'and whenever vthe water rises above the maximum fixed upon, the oat I) rises, the arma ofthe level' is borne upward, and the aperturev r registers with the steam-tube N, when the whistle blows. On the other hand, if the water falls below the proper line of dej- A`maroation,`the tube 0 is brought down so low that aperture q registers with the ltube1\T,when the whistle alsohlows.

Having thus described all that is necessary to a clear understanding of' my invention,

What I claim as new,a.nd desire to protect-.by Leb.
