Complete Specification Accepted, 7th Sept., 1888
We, ALFRED HASLAM of 110 Oxford Grove, and JOHN SETTLE of 305 Vernon
Street, Engineer, both of Bolton in the County of Lancaster, do hereby declare the
nature of our said invention to be as follows:-
Our invention relates to improvements in the construction of domestic and other
analogous fire-places or grates and consists in providing an ordinary house fire or
other similar grate with a metallic frame laid at the bottom or otherwise of the present
arrangements and connected by square or other rods in any convenient manner.
The ends of the frame are provided with bearings in which are mounted suitable fire-
bars of the alternate toothed form, interlocking with each other, with the pivots or
centres at each end of the bars and so disposed in the carrying frame that the points
of the teeth of the bars can be raised to break up the fire and clean out the fine
ashes. Suitable air spaces are provided between the interlocking teeth of the bars.
The back bar is operated by suitable projections from the front bar which is provided
with a preparation to receive a bar to rock and move the same in either direction.
The bars and frame can be fixed at any desired point in the fire-grate; the latter being
provided with an ash-pan or its equivalent to receive the dust and ashes and facilitate
the removal of the same and ensure cleanliness. We construct our improved apparatus
in various forms to suit the different constructions and arrangements of domestic and
other similar fire-places.
The advantages of this invention are that the use of the ordinary poker is almost
dispensed with; raking or scaling out the fire more effectually performed, as well as
that of more thoroughly cleaning and breaking up a domestic or other similar fire
than hitherto.

Improvements in the Construction of Domestic and other Analogous
Fire-places or Grates.
We, ALFRED HASLAM of 110 Oxford Grove, and JOHN SETTLE of 305 Vernon
Street, Engineer, both of Bolton in the County of Lancaster, do hereby declare the
nature of our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The
Our invention relates to improvements in the construction of domestic and other
analogous fire-places or grates and consists in providing an ordinary house fire or
other similar grate with a metallic frame laid at the bottom or otherwise of the present
arrangements and connected by square or other rods in any convenient manner.
ends of the frame are provided with bearings in which are mounted suitable fire-bars
of the alternate tooth form, interlocking with each other, with the pivots or centres at
each end of the bars and so disposed in the carrying frame that the points of the
teeth of the bars can be raised to break up the fire and clean out the fine ashes.
Suitable air spaces are provided between the interlocking teeth of the bars. The
back bar is operated by suitable projections from the front bar which is provided with
a preparation to receive a bar to rock and move the same in either direction. The
bars and frame can be fixed at any desired point in the fire-grate; the latter being
provided with an ash-pan or its equivalent to receive the dust and ashes and facilitate
the removal of the same and ensure cleanliness. We construct our improved apparatus
in various forms to suit the different constructions and arrangements of domestic and
other similar fire-places.
The advantages of this invention are that the use of the ordinary poker is almost
dispensed with raking or scaling out the fire more effectually performed, as well
as that of more thoroughly cleaning and breaking up a domestic or other similar fire
than hitherto.
Fig. 1 is a sectional elevation of a domestic or other analogous fire-place or grate
constructed according to our invention-Fig. 2 is a plan of same, and Fig. 3 is a
side elevation showing outside frames for carrying our improved rocking fire-bars.
A is the ordinary domestic fire-place or grate; B are the ordinary front grate-bars
at present employed in domestic and other similar fire-places. On the ordinary
metallic plate or bottom we mount the side frames D at each end of the fire-place,
and connect them with the square rods E screwed at each end and secured by the
nuts F. The front end of the side frames D hook on to one of the front bars B as
shown in Figs. 1 and 3. The frames D are provided with bearings in which are
mounted loosely the rocking bars G and H with the centres 1 and J respectively.
The rocking bars G and H are provided on one side only with the fire-bars K and L
respectively of the alternate toothed form interlocking each other, by which the bars K
and L will tilt upwards only as shown in Fig. 4, when operated to break up the fire
and clean out the fine ashes. Suitable air spaces M are provided between the fire-
bars K and L as shown in Fig. 2. The back fire-bars L are provided with the

page_text: crosspieces N underneath which operate the bars K¹ when the latter are raised by a
poker or bar O as in Fig. 4. The rocking bar G is provided with the socket P to
receive the end of an ordinary poker or the bar O as shown in Figs. 1 and 4, by
which the whole of the bars are tilted as in Fig. 4. If desired the underside of the
fire-grate can be supplied with the ash-pan R as in Fig. 3 to collect the dust and ashes
to facilitate removal of the latter and ensure cleanliness. To prevent the fire being
forced through the spaces between the bars B when operating the tilting fire-bars K
and L we provide the longitudinal bars S mounted in the side frames T, the latter
being supported on the centres U on the frames D.
In another modification we construct the bars L and frame D in one piece as shown
in Fig. 6, of which Fig. 5 is a section through line C¹ D¹. In this arrangement the
back bars L are stationary and the fire is broken up by tilting the fire-bars K only as
shown in sectional elevation in Fig. 7. The bars K are cast to the rocking bar G
provided with the centres I mounted in the bearings W in the frame D. The bars K
are tilted as in Fig. 7 by placing a screw-key or spanner on the square end X. To
prevent the tilting bars dropping too low the projections Y are provided, which operate
against the inside of the front face of the frame D as in Fig. 5.
Each fire-bar K and L can be made separately and mounted on the square bars G
and H; the latter being mounted in square bearings to ensure the bars supported
therefrom being stationary as shown in Figs. 8 and 9. The object of making the
tilting and stationary bars in sections is to allow of their being easily replaced in case
of breakage at the least possible cost. The front supporting or rocking bar G is
turned at each end and sits in the bearings Z in the frame D; the bars being
operated in either direction by a bar placed in the socket P cast on one of the
bars K.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
1. The use, in a domestic and other analogous fire-place or grate, of the front and
back tilting fire-bars provided with pivots on one edge so that they will tilt
upwards only, substantially as described and as shown on the drawings in Figs. 1, 2,
3, and 4.
2. The use, in a domestic and other analogous fire-place or grate, of the side
frames D with bearings for supporting the tilting fire-bars, substantially as described
and illustrated on the drawings.
3. The use of the crosspieces N on the tilting fire-bars for the purpose specified.
4. In a domestic and other analogous fire-place or grate the combination and
arrangement of stationary bars L, frame D, tilting bars K with their pivots on the
outer edge so that they will tilt upwards only, substantially as described and shown on
the drawings in Figs. 5, 6, and 7.
5. In a domestic and other analogous fire-place or grate the combination and
arrangement of movable and stationary fire-bars constructed in the manner described
and set forth on the drawings in Figs. 8 and 9.
