PROVISIONAL SPECIFICATION.
Improvements in Firebars, and Bearers therefor.
I, ZEPHANIAH WILLIAM BAUGH, of 12 Bratt Street, West Bromwich, in the
County of Stafford, Manufacturer, do hereby declare the nature of my said invention
to be as follows:-
My invention has for its object improvements in fire bars and their bearers by
which means I first provide a fire bar which is so serrated or perforated that the
air, instead of passing away through the serrations in an horizontal direction, is
deflected and thus caused to take an upward direction and secondly: I provide a
bearer which allows the full length of the bar to be perforated or serrated from
end to end and these bearers may be used with similar success in the case of any
ordinary bars; and thirdly; may be adapted to any tubular flue.
In carrying my improvement into effect I serrate the top of my bar crosswise in
a circular form thus preventing the air current from so easily passing from one side
to the other and thereby giving it an upward direction & through the fuel and yet
there are no sharp corners to become clogged. In the case of my bars I divide
them up say into three parts in proportion to their length, and form a square or
bearing surface on the underside which are made so as to rest upon my specially
constructed bearers which are preferably of a diamond section with the exception
of a small square at the top to receive the bar, and thus there is little or no
interference with the upward current of the air and these bearers may be perforated
with holes to retain them as cool as possible. These bars or bearers either
separately or together are particularly applicable to locomotive traction tubular
boilers & furnaces of all kinds.

I, ZEPHANIAHI WILLIAM BAUGH, of 12 Bratt Street, West Bromwich, in the
County of Stafford, Manufacturer, do hereby declare the nature of my said invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:
My invention has for its object improvements in fire bars and their bearers by
which means I first provide a fire bar which is so serrated or perforated that the
air instead of passing away through the serrations in an horizontal direction is
deflected and thus caused to take an upward direction and secondly I provide a
bearer which allows the full length of the bar to be perforated or serrated from
end to end and these bearers may be used with similar success in the case of any
ordinary bars and thirdly may be adapted to any tubular flue.
In carrying my improvements into effect I serrate the top of my bar crosswise in
a diagonal or circular form thus preventing the air current from so easily passing
гр.

page_text: from one side to the other and thereby giving it an upward direction and through
the fuel and yet there are no sharp corners to become clogged. In the case of my
bars I divide them up say into three parts in proportion to their length and form a
square or bearing surface on the underside which are made so as to rest upon my
specially constructed bearers which are preferably of a diamond section with the
exception of a small square at the top to receive the bar and thus there is little or
no interference with the upward current of the air and these bearers may be
perforated with holes to retain them as cool as possible. These bars or bearers
either separately or together are particularly applicable to locomotive traction
tubular boilers and furnaces of all kinds.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements. together with
the mode of carrying the same into effect.
Figure 1., is a broken off view of my fire bars and bearers in relative position.
Figure 2., is a section through the bearers showing the bar in elevation.
Figure 3., is a view of my improved bar.
Figure 4., is a plan of Figure 3.
Figure 5., is a section through the bars showing the bearer in position in the
boiler.
My improved bearer and bars consist of a serrated top A having a supporting
flange A upon its underside which is divided into two, three, or more lengths by
the square seatings a³ which are formed to fit the top of the specially constructed
bearers B which is provided with the square bearing surface 6 formed to receive
the seating of the bar. This diamond-shaped bearer offers to slight resistance of
the upward current of the air while they may be perforated with holes to retain
them as cool as possible. Rods or bars may be provided to pass through the
bearers and thus prevent them from tilting out of position longitudinally while cross
ends are provided to prevent them twisting out of position in the reverse
direction. By this means the whole of the bars and bearers are retained in
position in such a manner that they can readily be withdrawn or replenished at
any time.
In place of the diagonal or square serrations to the bars I may serrate the top
of the bar in a circular form as shown by Figures 3 and 4 in which the blocks are
divided by the circular dividing slots as thus preventing the air current from so
easily passing from one side to the other & giving it an upward direction through
the fire thus assisting to obtain a more perfect combustion.
Having now particularly described and ascertained the nature of my said improve-
ments & in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in fire bars and their bearers substantially as and for the
purpose herein set forth and shown upon the accompanying drawings.
2nd. The fire bars A having seatings a³ in combination with the bearers B
substantially as & for the purpose herein set forth.
3rd. In fire bars the circular serrated top substantially as and for the purpose
herein set forth and shown by Figures 3 and 4.
