Improvements in Steam Boiler and other Furnaces.
I, JOHN JAMES WHITTAKER, of 33, Avenue Parade, Accrington, in the County
of Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My improvements relate to steam boiler and other furnaces, and are improve-
ments on Patent No. 13972/95.
The object is to obtain more air space through the bars and make the bars in
one or more lengths with a jointing cover plate; for the better combustion of
fuel and to minimize the warping of bars.
In carrying out this improvement I have dead plates and brackets for carrying
troughs and bars as described in Patent No. 13972/95.
In providing more air space through the bars I cut away part of the centre
rib of bar which makes the air spaces longer, and to prevent the ashes getting
into the troughs I cast angle pieces on the underside of the teeth of sufficient
width to cover the troughs.
When making the bars in two or more lengths I provide a cover plate with a
recess for the reception of projecting pieces cast on the underside of bars to
prevent the bars moving away from each other.
This cover plate may be cast in one piece with the trough if required.

This cover plate may be cast in one piece with the trough if required.
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:-
1st. The combination of furnace bars with angle pieces on the underside,
with water troughs as and for the purpose set forth.
2nd. The combination of furnace bars with angle pieces on the underside and
projecting pieces on the ends, with a cover plate having a recess for the reception
of projecting pieces for jointing two or more lengths of bars as and for the
purpose set forth.
