sTEANBonER ATTACHMENT TO PREVENT Ex-
PLOsIoNs AT THE FAIR OF THE AMERICAN
INSTITUTE.
An extraordinary new invention, which stands
alone in an unoccuped field ana which has been exam
,ned by President Barnard OF Columbia College, and
many Of the most eminent practical engineers and me-
chancans the Exhibition, aud pronounced By them to
be complete success and toful requirements

motive and other steamboers and will certainly equal
ize automatically the temperature Of an parts OF the
boiler and It's contents under any condition of heating
to within very few degrees of constant uniformity so
that whether the water chances TO DO high low from
earelessness or inaentiOn. that portions OF the
heating surface become uncovered by water. and the
steam begins to be heated above the temperature due to
s pressure valves are opened and the wHer from the
bottom of the boiler is instantly brought up snd Injected

constantly keeping ut nearly fe temperature due TO its
pressure and simply and effectively at small cost pre-

costly repair which largely eat needessy
much of the profits OF railroads and steamers
This invention Is based upon the discovery that steam
