Improvements in Firegrates or Stoves.
1, JOSEPH RIGBY, 7, Extension View, off Robins Lane, Sutton, near
St. Helens, Lancashire, retired Grocer, do hereby declare the nature of this
invention to be as follows:-
An improvement for kitchen fire grates, & for all other grates such as bedrooms
and parlour grates or stoves, with open fire places to be worked as shown on the
plan by back draught; it will save in fuel in each grate from sixpence to a shilling
per week, as it will consume the commonest of coal or slack, & burn up all cinders
and will save the Corporation a deal of carting, and will improve the night soil by
excluding all cinders from it, the angle to be altered to suit differant discriptions of
fire places and to be put in as shown on the plan or with a plain angle it will be a
great benefit in heating ovens and ironing and casting more heat into the rooms as
the heat will be on the front bars, the heating to be regulated by opening & closing
the swing door or damper as it may be called as shown on the plan.
Fig. 1. A triangular prismatic frame hollow and without bottom with bars on
the long side slanting towards the bottom of the front bars inside the frame is a
swinging damper marked c Fig. 2 which can be brought up close to the bars
by means of the handle (marked d in Fig. 2) when it is desired to shut off the
draught.

Improvements in Firegrates or stoves.
I JOSEPH RIGBY 7 Extension View off Robins Lane Sutton near St. Helens
Lancashire retired Grocer 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 :-
An improvement for kitchen firegrates & for all other grates such as bedrooms
and parlour grates or stoves with open fireplaces to be worked as shown on the plan
by back draught it will save in fuel in each grate from sixpence to a shilling per week
as it will consume the commonest of coal or slack & burn up all cinders and will
save the Corporation a deal of cartage and will improve the night soil by excluding
all cinders from it the angle to be altered to suit different discriptions of fireplaces
and to be put in as shewn on the plan or with a plain angle it will be a great benefit
in heating ovens and ironing and casting more heat into the rooms as the heat will
be on the front bars the heating to be regulated by opening & closing the swing
door or damper as it may be called as shewn on the plan. The drawings herein
referred to are those which were filed with my Provisional Specification.
Fig. 1. A triangular prismatic frame, hollow and without bottom with bars on
the long side slanting towards the bottom of the front bars inside the frame is a
swinging damper marked c Fig. 2 which can be brought up close to the bars

page_text: by means of the handle (marked d) in Fig. 2, when it is desired to shut off the
draught.
Figure 3 is a front elevation & Figure 4 is a section of a stove fitted with the
prismatic frame. The structure of the prismatic frame is built in at the back of
firegrate.
The novelty in the structure is to keep the back free from dust & to give the air
a free passage which enables it to burn up inferior fuel.
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
That with this improvement an inferior class of coal may be burnt owing to the
increased draught and a greater amount of useful heat will be obtained from a
smaller amount of fuel.
