PETER HOLLAND 4 Carter Street Higher Broughton Manchester Piston-ring
Maker, do hereby declare the nature of this invention to be as follows:-
The invention is for an improved form of fire-bars and fire-bar bearers for use in
steam boilers.
The top surface of the bars and bearers being made convex, or angular, or higher
in the centre than at the sides.
These bars or bearers can be made suitable for any boiler, the amount of crown,
or angle required, being determined according to size of boiler. Fire bars of this
description would be used for round or square fire places in vertical boilers. When
in position the bars would be placed to taper downward from the centre to the
circumference, the upper surface of the bars forming a complete conical surface.
For oblong fire places in longitudinal or horizontal boilers fire bar bearers, with
the upper surface convex or angular or higher in the centre than at the sides, would
be employed on which the ordinary straight fire bars could be placed.

Maker 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 :-
Figure 1 on drawing shews the improved fire-bars placed in position in a square
fire-place. As will be seen from the section through A. B, the top surfaces of the
bars, on which the coal is deposited, instead of being flat straight across as in the
ordinary way, are made convex, or higher in the centre than at the sides, and from
the front elevation, it will be seen that the top surfaces of the bars, are also made
convex transversely, the upper surface of the bars thus forming a complete convex
surface, with its highest point at the centre of the two diagonals. The amount of
crown required, would be determined by the size of fire-place. Bara of this
description would be used in either round or square fire-places.
Figure 2 shews the improved form of fire-bar bearers. The bearer, instead of
being flat straight across, is made with the upper surface convex, or higher at the
centre than at the ends. These fire-bar bearers, would be used in longitudinal fire-
places, and when the ordinary straight fire bars are placed and fitted on the crown
shaped bearers, the upper surface of the bars as seen from the end elevation will
form a convex surface.
Figure 3 also shews the improved form of fire-bar bearers. Instead of the upper
surface being made crown shaped, the top sides are made angular, the taper being
gradually upward from the ends to the centre.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.
1. Fire bars for round or square fire-places, with the upper surface of the bars
made convex.
2. Fire bar bearers for longitudinal fire-places with the upper surface made
convex.
3. Fire bar bearers for longitudinal fire-places, with the upper surface with taper
or angular sides.
Dated this 25th day of January 1895.
