PROVISIONAL SPECIFICATION.
Improved Slow Combustion Coal Saver for use in Fire Grates.
HORATIUS JOHN BOLTON HOLLAND Iron & Tin Plate Worker Pearson
Street Mill Blackburn I do hereby declare the nature of this invention to be as
follows:
My invention is an improvement in appliances used in fire grates on my own
Patent taken out 22 Oct. 1885, No. 12643.
The improvement is as follows, I do away with a middle cross bar, and also
2 flat bars, and instead of the 2 flat cross bars, which obstruct the ashes from falling
through, I replace with 2 half round bars which answer the purpose without
holding the ashes, thereby giving a cleaner and brighter fire.
Dated 17th day of October 1891.

COMPLETE SPECIFICATION.
Improved Slow Combustion Coal Saver for use in Fire Grates.
I HORATIUS JOHN BOLTON HOLLAND, of Pearson Street Mill Blackburn in
the County of Lancaster Iron Worker, 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 appliances used in the ordinary domestic
fire grates and consists of further improvements in appliances for which Her
Majesty's Royal Letters Patent No. 12643 were granted to the present applicant
and dated the 22nd day of October 1885.
According to this my present invention, I dispense with the middle, or cross bar,
and also the two flat bars which are described in the Specification of Patent as
aforesaid, as in practice I found that the two flat bars prevented the ashes from
falling through the bottom of the fire grate, and obstructed the free access, or
draught of air to the underside of the fire, but by substituting two half round or
convex bars, in lieu of the flat ones the ashes are allowed to pass through the bottom
of the grate, and the current, or draught of air passing therethrough causes the fire
to burn clearer, and brighter.
Such being the nature, and object of my said invention the following is a
complete description of same reference being made to the accompanying drawings
in which :-
Fig. 1 is a front elevation of my improved slow combustion coal saver.
Fig. 2 is a sectional end elevation of Fig. 1.
Fig. 3 is a plan view of Fig. 1.
According to this my present invention the coal saver is made in the ordinary
manner, and consists of a series of bars 1. 1. held together by cross bars, or
stays 2. 2. and one, two, or more of the bars 1 are bent to the shape shewn at 3 by
Fig. 2 so that when the saver is placed inside the fire grate, the parts 3 pass
between the bottom grate bars, and so hold the saver steadily in the required
position.
Across the bottom of the saver, and at right angles, or transversely to the bars 1. 1.
I fix, preferably, two semicircular, or half round bars 4. 4 the circular, or convex
parts of the bars 4. 4 being placed upwards, or towards the fuel contained in the
fire grate, and the bars 4. 4 are fixed in position by turning over, or bending their
ends 5. 5. so as to encircle the outer bars 1. 1. to which they are secured.

page_text: By the use of the bars as above described the ashes produced by the combustion
of fuel in the grate, are allowed to pass through the bottom of the grate when the
fire is raked so that a free passage of air, or a draught, has access to the bottom
of the fire whereby the fuel is more effectively consumed, the result being that the
fire burns brighter, and cleaner, and the heat therefrom is thrown more directly
into the room, less fuel being used with better results than heretofore obtained.
Having now particularly described and ascertained the nature, and object of my
said invention, and in what manner the same is to be employed I declare that
what I claim is :-
-
1. The improved slow combustion coal saver constructed as herein described,
and having the half round bars 4. 4 fixed transversely, or at right angles to the
bars 1. 1. as and for the purpose herein described, and as illustrated by the
accompanying drawings.
