TIE CLOSING WEEK-THE ATTENDANCE-STEAM
BOILERS
This il the last week of the American Institute
Fair ON Saturday evening next it closes for the year 80
far, IL has been In every complete SUCCESS Tne
display of novel and curious productions and inventions
probably exceeds variety and general interest that OF
any previous year In the history OF the Institutes and of
tho standard articles which always expects to md In
exhibitions Of this kind, the specimens remarkably
good Tho people OF New-York have not been backward
i showing their appreciation OF the offered
them Upward Of persons have already visited the
Exhibition, and the whole number will undoubtedly ex,
100000 it's close The arrangement OF tho Fair ~
admirable. The articles on exhibition are so skifnly
creed even on st VISIT in finding any particular OBJ

Messs r. W and ID. Davis OF this city present style Ell
boiler combining great economy and safety with COM
pactness and durability. Starting With the idea
That the upright tubular boiler combines TO a
greater degree than any other OF the ordinary
forms these requisites, they have sought to
utizo the waste heat which usually escapes from
the tubes at the top To do this this they have placed
within tie smoke box at the top OF the boiler large
steam drum against and around which the heated air and
gas passes Around this steam drum again, and directly
number OF hollow spheres Of cast iron. connected TO
each other by short tubes These spheres form super
heater of the most efficient kind. The steam, having
been already dried and partially superheated IN the
drum, passes TO the first of these spheres,
ard thence through each one successfully 10
the last whence IL goes 70 the engine It Is
Thus cnectuaIY euperheatcd separately from the
10 an unequal heating OF different parts OF H. and do
this with tile heat which in the ordinary boiler Is allowed
10 go 10 waste As still further economic and safe pre-
caution all tho tubes except the outer row, closed at
the top hy capa. each perforated with single small
hole 80 that the drnught and heat are drawn chiefly
through the outer tubes against the greatest body OF
water while the inner tubes become heating-chambers
without allowing the escape OF heat This arrange
nnt prevents the concentration Of heat against the
center OF the crown sheet, thus avoiding the danger
OF lifting tho water and burning the sheet.
one OF the Messrs Davis's boilers, rated at 25horse
mower has been employed during the Fair to furnish
stearn 10 BabcOci and Wilcox engine rated az 60horhe
noWrr aud working at from one half 20 twothirds or ITS
capacity This task 10 has successfully accomplshed-a
fact which speaks exceedingly wei Tor the economy VI
both boiler nnd engine.
