Improvements in and relating to the Construction of Seats for Back
Boilers of Kitchen Ranges.
I, RICHARD HAMPSON, of 7, Devonshire Street, Accrington, in the County of
Lancaster, Range Fitter, do hereby declare the nature of this invention to be as
follows: :―
This invention has reference to certain improvements in and relating to the
construction of seats for back boilers of kitchen ranges, such boilers as is well
These seats
known being used for supplying hot water to baths, lavatories, etc.
occupy a position underneath the bottom of the back boiler, the flue or draught
hole for conveying the hot air from the firegrate intervening between the seat
and the boiler, so that the hot air may pass under the bottom of the boiler,
and up the back to the chimney flue. Now, these seats usually take the form
of a cast iron plate or dead plate having_supporting bricks at the sides, on
which the bottom of the back boiler rests. In course of time, when it is desired
to clear this dead plate or seat of ashes, which accumulate thereon from the
fire-grate, the ashes have to be raked forward into the fire-grate, covering
various articles about the range with dust.
This invention is chiefly designed to provide means for the discharge of the
ashes into the open space below the boiler seat and beyond the fire-grate, so that
such ashes may find their way into the ashes draught at the back of the range,
and is also designed to protect the bricks or other supports from damage when
stirring or poking the fire. These bricks have often to be replaced owing to the
damage done to them.
According to my invention, I form a square or round hole in the bottom of
the boiler seat provided with bevelled edges, into which fits a small lid having
corresponding bevelled edges, and formed at the top in the centre with a
countersunk hole, strid by a cross bar, by which such lid may be readily raised
by a hooked rod or the like, and the ashes raked through the hole at the bottom
of the boiler seat.
The boiler seat is also cast with angular protecting plates on each side of the
draught hole, and also the front portion facing the fire. The angular plates are
at right angles to the boiler seat, and take the respective corners of the fire-
bricks supporting the back boiler at each side, thoroughly shielding them from
damage. The angular plates forming the corners of the draught hole may be
rounded at the corners.
The front top portion of the angular plates may be formed with bevelled
edges running inward, and a cast iron perforated fire-back having bevelled
edges at the bottom may be fitted on to the same.

I, RICHARD HAMPSON, of 7, Devonshire Street, Accrington, in the County of
Lancaster, Range Fitter, 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 has reference to certain improvements in and relating to the
construction of seats for back boilers of kitchen ranges, such boilers as is well
known being used for supplying hot water to baths, lavatories, etc. These seats
occupy a position underneath the bottom of the back boiler, the flue or draught
hole for conveying the hot air from the firegrate intervening between the seat
and the boiler, so that the hot air may pass under the bottom of the boiler,
and up the back to the chimney flue. Now, these seats usually take the form
of a cast iron plate. or dead plate having supporting bricks at the sides, upon
which the bottom of the back boiler rests. In course of time, when it is desired
to clear this dead plate or seat of ashes, which accumulate thereon from the
fire-grate, the ashes have to be raked forward into the fire-grate, covering
various articles about the range with dust.
This invention is chiefly designed to provide means for the discharge of
ashes into the open space below the boiler seat and beyond the fire-grate, so that
such ashes may find their way into the ashes draught at the back of the range,
and is also designed to protect the bricks or other supports from damage when
stirring or poking the fire. These bricks have often to be replaced owing to the
damage done to them.
According to my invention, I form a square or round hole in the bottom of
the boiler seat provided with bevelled edges, into which fits a small lid having
corresponding bevelled edges, and formed at the top in the centre with a
countersunk hole, strid by a cross bar, by which such lid may be readily raised
by a hooked rod or the like, and the ashes raked through the hole at the bottom
of the boiler seat.
The boiler seat is also cast with angular protecting plates on each side of the
draught hole, and also the front portion facing the fire. The angular plates are
at right angles to the boiler seat, and take the respective corners of the fire-
bricks supporting the back boiler at each side, thoroughly shielding them from
damage. The angular plates forming the corners of the draught hole may be
rounded at the corners.,
The front top portion of the angular plates may be formed with bevelled
edges running inward, and a cast iron perforated fire-back having bevelled
edges at the bottom may be fitted on to the same.
In the accompanying drawings, Fig. 1 is a perspective front view of a back
boiler seat for kitchen ranges, constructed in accordance with my invention.
Fig. 2 is a perspective view of the seat and boiler with fire-back in position.
The seat A is cast or formed with upright iron corner plates or blocks B C
on each side, which protect the supporting bricks 1 from injury or damage by
fire or poker. These corner plates take the respective corners of the boiler seat
adjacent to the fire space, as shewn. The cost of renewing is thereby saved,
which is frequently entailed when the bricks are unprotected.
The seat is also formed with a square or round hole, such as E, having bevelled
edges, into which closely fits loose cover F (see Fig. 2). The said cover may

page_text: be removed by hooked rod G, and for this purpose may be constructed with cross
bar H and recess. The cover preferably comes flush with the bottom of the seat.
By the removal of loose cover F in the manner aforesaid, the flue under boiler
can always be kept clean, as any accumulated ashes may be raked through
opening E into the ashes draught underneath.
In combination with my improved back boiler seat as described, may be used
a perforated protection plate or fire-back J, which may be constructed with
bevelled edge at the bottom to fit upon corresponding bevelled edges K at the
top of the upright corner plates. This iron fire-back protects the copper boiler L
from damage by the poker, whilst the perforations allow of the heating of the
water in the boiler.
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. The improved construction and arrangement of seats for back boilers of
kitchen ranges, substantially as described and illustrated.
2. A seat for back boilers of kitchen ranges provided with upright iron corner
blocks or plates B C at the respective corners adjacent to the fire space, sub-
stantially as and for the purpose described and shewn.
3. A seat for back boilers of kitchen ranges having opening E and loose
cover F in combination with upright corner plates B C at the respective corners
adjacent fire space, substantially as described and shewn for the purpose specified.
4. A back boiler seat for kitchen ranges provided with opening such as E
and loose cover F substantially as and for the purpose described and shewn.
5. A perforated fire-back J having bevelled edge to fit corresponding bevelled
edges K at top of upright corner plates in combination with my improved con-
struction of boiler seat, substantially as claimed in Claims 2 and 3.
