STOKING AND SMOKING.

The Device In Use at tho Cincinnati
to1iIng-Hzfll-!AM Mcclaa si1cal Arrange

| Work Well In large establishments Il
but Tao Complicated for Small Ones.
An ordinance has been passed by the Coun
| ell and has received the signature of th
| Mayor which Is intended to compel manu-
! factutcrs and others to use some method 70
| consuming the smoke from their establish
ments. This naturally turns the attention
| Of those WHO will come under the pro
visions Of this ordinance, as we'll as other:
interested, to the many different device:
which have been invented for this purpose
For those invented it has been claimed
that they would perfectly consume the
smoke, but subsequent trials have resulted
in only partial consumption in the case OF
many.
There is, however: one in operation now at
the Cincinnati Rolling-Alill Company's est;b-
lishnent which, it is believed, as nearly
overcomes the aforementioned fault as it Is
possible to be done.
It is the Invention Of Afr. Samuel Danks.
General Superintendent OF the above-nanled
co1lpary's works. Mr.. Danks says lie does
not call his device a ''smokc consumer" but
mechanical stoker and smoke preventer,"
and which it truly is. It is simple in its con-
struction and most effective il, its working.
a reporter OF the Gu5ettc, visiting the Gin
cinnali Rolllns-Nlll recently, saw the "snloke
preventer" i'll operation, and had it explained
by Alr. Danks.
The fire-grate for the boilers is like an or
dinary one, but is set outside, with bridge
wall bnck. which is even with the front of
the boilers. This CRATE is inclosea with walls
of tireDrlck. In front Of this sort Of oven is Il
hopper made Of iron plates divided into four
compartments. Through the bottom of each
OF these compartments runs screw or
anger, Oh the end OF which, outside the
hopper, is ratchet an wheel. , .a, Ials ansef S
BY an engine, to which is attached q "paw"
that works in the ratchet wheel on the end of
the anger, turning 1t one, two three, or rs
many notches At Il time rs is thought neces-
sary, In the hopper is placed the coal. and
the turning of this ,auger carries. it into the
furnace with its blades, fast or slow, accord
ing to the speed Ut the machine. Running
under the grate-bars into the ash-pt is u
pipe, through which (: blast from 4 fam
blower is forced with 4 pressure OF about
OF a pound more than the ordinary
Iaa d491 ot the a*
through the fuel. and all the volatile matter
Of the coal, which is the cause OF smoke,
necessarily passes through the highly in
fuel. This gas is mainly carbonic
oxide. Now, to counteract this. a large pipe
runs to the toI, Of the furnace, in which are
il VI LltUES+ du t!ttf1 iH
diameter, running through the roof OF the
furnace. Through these tubes part Of the
same blast Is blown down into the gases
rlSi1M from below, BY reason 1T the blast from
beneath the fuel, and is mixed with them.
This blast is regulated by valves SO that it
caI be increased or diminished, and so effect !
! perfect combustion Of the carbon, anil con- |
vert this carbonic oxide gas into carbouic |
tcid gas. 4 damDer is inserted in OF OIL the !
chimney to regulate the outflow Of gase5, as |
t is found desirable to maintain 4 slight |
Internal pressure above the natural pressure ]
II the atmosphere, for the purpose OF giving /
he blast time to mingle thoroughly with tue ]

lem time to burn. In this way Z perfect |
OF fuel and gases is obtatlleu, re-
hitting in 4 great saving OF fuel. The open |
ng from this furnace into the Space u!l-
Ter the boilers is about two feet square, anu
lie space under. the boilers is much higher [
han III most furnaces. The usual hight
t this space is but a few inches, the oo-
yet being 10 keep the flame near the boilers;
The principle upon which this device Is BASEL
) that the gases rising from the combustion
t TIC fuel, coming in contact with the 9o!l-
rs filled with water, are cooled nif al;d drop
own and pass off beforc they are entirely
onsu1ned. The blast used in this dcvlce
orceS these gases to rise rs fast as they be-
olne cooled, and being met BY the blast fruit

stect a perfect combustion before they pass
The hoppers for receiving the coal can be
lade as large and divided into as many COM
as is Necessary. 3lr- DankS is
