COMPLETE SPECIFICATION,
Improvements in Smoke Consumers.
ALEXANDER
MELHADO, Counsellor-at-Law, both of No. 234 Broadway, in the City and State
of New York, United States of America, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
We, EDDY TAYLOR THOMAS, Consulting Engineer, and
The object of this invention is to prevent smoke and assist combustion in burning
soft coal and particularly to prevent smoke while steam is being generated in the
main boiler.
Our invention consists in a supplementary generator or boiler, an adjustable jet
pipe, two generator pipes leading into a jet pipe, an adjustable deflection plate and
a heating device.
Fig. 1. represents a longitudinal section of a furnace having several appliances
forming our improvements.
Fig. 2. is an end view of Fig. 1. showing the generators and pipe connections.
Fig. 3. is the furnace door and frame having jet support and recess for the
deflection plate lever.
Fig. 4. shows the generator pipes leading into the jet pipe.
Fig. 5. shows the jet pipe and supports and
Fig. 6. shows how an extension frame may be secured to the furnace frame to
support the deflection plate.
A. Fig. 1. represents the necessary part of a furnace and boiler to show the
general improvements.
A Figs. 1. and 2. is a furnace boiler of usual construction adapted to rapidly
generate steam.
B. Figs. 1. and 2. is a feed pipe which is coupled to the union C. and enters the
boiler A at B', it is provided with a cock B' by which the steam from the boiler A¹
to the jet pipe 1) is controlled.
F2 Figs. 1. and 2. is a small boiler in which steam is quickly generated, it is
supported to the wall or partition N. by brackets F3; G. Figs. 1. and 2. is a
pipe supported by the brackets G and has a series of holes G2 through which gas
passes, which when burning forms the flame G³, that intense heat may be obtained,
with a small percentage of gas, air is allowed to mingle with gas through holes in
the bulb, G on the principle of the well known Bunsen burner.
F. Figs. 1. and 2. is a feed pipe secured to the boiler F at F1 and is coupled to
the union C., it is provided with the cock F by which the steam from the boiler F
to the jet pipe D' is regulated.
C. Figs. 1. 2. and 4. is a union joint having lugs C and C2 to which the feed
pipes B. and F. are fastened, it is provided with two passages C3 and C4 which'
lead into a single passage D' or pipe D¹.
D. Figs. 1. and 2. is a stop cock set into the head D10 by which the steam is
turned into or shut off from the jet pipe D.
D' Fig. 5. is an adjustable cock plug having a jet pipe D and a recess D
opposite the opening Ď which allows the steam to enter the chamber D", the
recess D³ is of sufficient width to always be opposite the hole D' whenever the plug D'
is turned by the bandle D to elevate or lower the jet pipe D' that the jet of
steam may be guided just above the fire bed.

page_text: The head D Fig. 5. has an opening D which extends to the walls D' D* and
forms a stop for the jet pipe D. that it may not be raised or lowered too far.
That the jet pipe D' may be extended into the furnace a passage D' is formed
in the door frame M. and mason work M' as shown in Figs. 1 and 2.
E Figs. 1. 3. and 6. is an adjustable deflection plate (having a detachable
plate E held by bolts E Figs. 1. and 3.) supported on the shaft E which is held
in the mason work or extension frame M Fig. 6. by the journal bearings Eas
shown by dotted lines in Fig. 3. and is made adjustable by aid of the lever E.
which is fastened to the plate as shown in Fig. 3. or it may be integral with the
plate.
E Eigs. 1. and 3. is a rack having notches E' which engage with a snap pin (not
shown) on the lever E. and holds the deflection plate E in the proper adjustment
to guide the air from the draught holes A downward; that the lever E' may have
the proper adjustment a space E' is cast in the door frame M. Fig. 3. and a
recess is left in the mason work as shown in Fig. 1.
The operation is as follows: When steam is to be generated in boiler A', the
Bunsen burners G. are lighted, which quickly generates steam in the boiler F³,
the fire is then started in the furnace A., the cock B2 is closed to prevent steam
from entering the pipe B. or boiler A', the cocks F and D. are then opened which
permits a jet of steam to be forced through the jet pipe D' over the burning
coal and prevent the smoke from escaping, when steam has been generated in
the boiler A the Bunsen burners G. are turned out, the cock F* closed and the
cock B opened permitting steam from boiler A to be used, by this plan it is
readily seen that no smoke is allowed to escape while steam is being generated
in the large boiler A' as was the case previous to this invention.
When a high fire is built as shown by line A' Fig. 1. the jet pipe D' should be
set to the highest point, but in case of a low fire as A' the jet D' should be set at
a low point or between the two extremes.
When a new fire is to be built or coal to be put on, the fireman by aid of the
handle E pulls the lever E. down, which raises the deflecting plate E' out of
the way.
The modification in Fig. 6. shows the deflecting plate E journalled to an
extended frame M2, instead of the mason work, in which case the furnace door A
is dispensed with, the deflecting plate taking its place and forming a closed
aperture to the fire-hox as it rests against the flange M but when opened as shown
by dotted lines E the air is permitted to pass and when coal is to be put on the
fire, the plate is raised as shown in dotted lines E10; this plan will be adopted in
applying the improvements to old furnaces.
The boiler F may he used to contain compressed air or gas which would answer
the same purpose as steam.
Water may be sprayed into the boiler F through the valve F which would
require less heat than by using a large amount of water in one body.
We do not desire to be limited to one jet pipe D as two may be employed, one
from each boiler instead of using the union C.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
First. The boiler A' having pipe B. in combination with the adjustable jet
pipe D as and for the purpose described.
