page_text: I, YOUNG JOHN HAMILTON, of 32 Sydney Avenue, Blackrock, Dublin, Ireland, do
hereby declare the nature of this invention to be as follows:-
This Invention relates to improvements in the construction of Furnace Bars for
Stationary, locomotive, and other engines and is especially adapted for Brewers and
distillers Furnaces.
It is designed to afford amongst other advantages greater lightness, and durability
than bars hitherto in use; and also to diminish the quantity of smoke caused by the
burning of the fuel in the furnace.
The nature and construction of my said invention will be readily understood on
reference to the accompanying drawings in which Fig. 1, represents a plan and Fig. 2
a longitudinal elevation of my improved furnace Bar.
The bar is formed of one solid casting; a, a, being the bar proper, and b, b, the
strengthening portion; c, c, are vertical slots or apertures pierced through the bar for
the admission of air-These slots are splayed, or dished downwards both transversely,
and longitudinally as partly represented by the dotted lines in Fig. 2, the object being
to facilitate the falling through of burned fuel, and also to further facilitate the current
of air.
The sides of the bar are provided with vertical grooves d, which form apertures
when two or more bars are placed together and which further contribute towards the
free admission of air-Longitudinal apertures e, e, are also provided in the ends, or
supports of the bar for the same purpose.
The parts i, i, of the strengthening portion of the bar are wedge, or inverted ✓ shaped
in section, for the purpose of reducing or diminishing the obstruction offered to the
falling of burned fuel.

page_text: I, YOUNG JOHN HAMILTON, of 32 Sydney Avenue, Blackrock Dublin Ireland,
Gentleman, 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 :--
This Invention relates to improvements in the construction of Furnace Bars, for
stationary, locomotive, and other engines, and is especially adapted for Brewers' and
distillers Furnaces.
It is designed to afford amongst other advantages greater lightness and durability
than bars hitherto in use; and also to diminish the quantity of smoke caused by the
burning of the fuel in the furnace.
The nature, and construction of my said invention may be more readily understood
ou reference to the accompanying Drawings:-Fig. 2 represents a plan Fig. 1 a
longitudinal elevation; Fig. 3 a transverse section on line a Fig. 1; and Fig. 4 an
end view of my improved Furnace Bar.
The bar is formed of one solid casting; a, a being the bar proper, and b, b, the
strengthening portion; c, c, are vertical slots or apertures pierced through the bar for
the admission of air-The longitudinal sides of these slots are splayed or dished down-
wards as shown in the sectional view (Fig. 3) the object being to facilitate the falling
through of burned fuel, and also to further facilitate the easy passage of air.
The sides of the bar are provided with vertical grooves d, which form apertures when
two or more bars are placed along side each other, and which further contribute
towards the free admission of air.
For the same purpose, as also and, moro especially when the Bar is used in com-
bination with a current of steam longitudinal apertures or chambers e, e, are
pierced through the entire length of the bar, provided with lateral passages f, on
each side.
The parts i, i, of the strengthening portion of the Bar are wedge or inverted V
shaped in section (see Fig. 3) for the purpose of reducing or diminishing the obstruction
offered to the falling of the burned fuel.
Having new particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would bave it understood
that I am aware of Patents having been hitherto granted for Furnace Bars of various
kinds, as likewise for improvements in Furnace Bars, having in some cases objects in
view, analogous to those for which this invention is designed, and to such Patented

page_text: Inventions I lay no general claim, but what I claim and desire to secure by Letters
Patent is
1st. In Furnace Bars the splaying or dishing of the apertures c, c, for the purpose
and in the manner herein described.
2nd. In Furnace Bars the use of the wedge or inverted V shaped tops i, i, for the
purpose and in the manner herein specified.
3rd. In Furnace Bars when used for the purpose herein described, and more
especially in combination with a current of steam, the longitudinal apertures e, e, and
lateral passages ff in the manner substantially as specified and set forth.
Dated this 25th day of February 1889.
