PROVISIONAL SPECIFICATION.
Improvements in Furnace or Fire Bars.
I, GEORGE BEELEY of Soho Foundry, Soho Street Sheffield in the County of
York Ironfounder do hereby declare the nature of this invention to be as
follows:-
This invention relates to furnace or fire bars and the objects are
1. To so construct and arrange the same that the weight of bars necessary for a
furnace is lighter than with furnaces arranged with ordinary bars.
2. To so construct each bar that the ash may more freely fall through or between
the same than is possible with ordinary bars and
3. To so arrange the bars that they become more durable and present a better
surface for the fire than ordinary bars, to attain which I form each middle bar with
a central web part and extending on each side of the upper part thereof I form
lugs or projections which are tapered both horizontally and vertically.
The projection on one side of one bar fills up the space between two projections
on the next bar and each projection has formed through it two or more vertical
oblong holes which are wider at their lower parts than at the top and each said hole
runs in the direction of the web of bar.
The surface of each bar is channelled on the top of web and over each projection
and each side bar of the furnace receives the said improved projections on one side
thereof only.
Dated this 27th day of November 1893.

COMPLETE SPECIFICATION.
Improvements in Furnace or Fire Bars.
I, GEORGE BEELEY of Soho Foundry Soho Street, Sheffield in the County of
York Ironfounder, 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 furnace or fire-bars and the objects thereof are
1. To construct and arrange the same that the weight of bars necessary for a
furnace is lighter than furnaces arranged with ordinary bars.
2. To so construct each bar that the ash may more freely fall through or between
the bars than is possible with ordinary bars and
3. To so arrange the bars that they become more durable and present a better
surface for the fire than is possible with ordinary bars.
To attain the said objects I construct my improved bars and arrange the same
substantially as described with reference to the accompanying drawings in which
Fig. 1. is a plan of a middle or inner bar and Fig. 2. is an enlarged cross section
of same taken on line a a of Fig. 1. and
Fig. 3 is a plan of outer or side bar.
Similar letters of reference denote corresponding parts in each view.
I form auch middle ber A with a contre web nart a' and extending on each side

page_text: of the upper part thereof I form lugs or projections a' which are tapered both
horizontally and vertically as shown at Fig. 2.
The projection a³ on one side of bar A fills up the space between two projec-
tions a' on the opposite or next bar and each projection a has formed through it
two or more vertical holes a³ of oblong shape and which are wider at their lower
parts than at the top as shown, Fig. 2 and each said hole a' runs parallel in the
-direction of the web a' of bar A. The surface of each bar is preferably channelled
on the top of web a' and over each projection a².
Each side bar A of furnace see Fig. 3, receives the said improved projections a³
on one side thereof only.
I would have it understood that I do not claim as my invention the channelling
of the bars nor the mere use of ordinary projections on one or both sides of a
web a¹ but
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
.I claim is :
1. In furnace or fire-bars A the combination with a web a' of horizontally and
vertically tapered lugs as having two or more oblong holes as through the same the
-said holes a being wider at their lower parts than at the upper and running parallel
to the web a¹ and arranged substantially as described and illustrated and for the
-attainment of the object specified.
Dated this 25th day of June 1894.
