We, FRANCIS BLANKLEY BRAMHAM and ALFRED JOHN CRIPPIN, trading as
Joseph Bramham, of 104, Dale Street, Liverpool, Hot Water Engineers, do hereby
declare the nature of the said invention to be as follows:-
-
This invention relates to boilers for heating and circulating the water of hot-
water heating systems.
A boiler according to this invention is of saddle form, with the usual flow and
return pipes. The boiler is internally fired by a furnace disposed within the
saddle. Such furnace may extend about two-thirds or three-quarters the length
of the boiler, and at the back of the furnace, and consequently about one-third
or one-quarter the length of the boiler from the rear end thereof, we form a water-
way or bridge, which passes from one side of the boiler to the other. Between
the top of this water-way or bridge and the concave crown of the boiler is a flue
space for the passage of flame and hot gases from the furnace, whilst the rear of
the boiler is check-ended, that is to say a water-way extends from the crown of
the boiler downwards to a point below the level of the bridge water way but does
not reach to the bottom of the boiler, thus forming a flue space.
The course of the products of combustion in the above described boiler is as
follows: The water way which forms a bridge to the furnace deflects the current
of hot gases upward so as to impinge against the crown of the boiler. The
meet
until they
the
gases then pass along the crown of the boiler
water-way end of the boiler against which they impinge and then travel
downwards and pass through the space underneath such water-way end. From
this point the products of combustion may be led through flues extending along
the outside of the boiler to the front thereof and then returned to the rear
thereof and thence to the uptake or chimney.

ment:
-
This invention relates to boilers for heating and circulating the water of hot-
water heating systems.
A boiler according to this invention is of saddle form, with the usual flow and
return pipes. The boiler is internally fired by a furnace disposed within the
saddle. Such furnace may extend about two-thirds or three-quarters the length
of the boiler, and at the back of the furnace, and consequently about one-third
or one-quarter the length of the boiler from the rear end thereof, we form a water-
way or bridge, which passes from one side of the boiler to the other. Between
the top of this waterway or bridge and the concave crown of the boiler is a flue
space for the passage of flame and hot gases from the furnace, whilst the rear of
the boiler is check-ended, that is to say a waterway extends from the crown of
the boiler downwards to a point below the level of the bridge water-way but does
not reach to the bottom of the boiler, thus forming a flue space.
In the drawings hereto annexed Figure 1 is a longitudinal section of our
improved boiler, set in brickwork. Figure 2 is an end view of the boiler.
Upon reference being made to the drawing it will be seen that across the furnace
space of the boiler we construct a water-way bridge a which extends to the bottom
of the boiler but does not reach as high as the crown, whereby a flue space exists
between such bridge and the crown. The bridge a is disposed a short distance
from the rear end of the boiler. Such rear end b is also a waterway, and extends
from the crown of the boiler to a level below that of the bridge a.
The course of the products of combustion in the above described boiler is as
follows: The waterway a, which forms a bridge to the furnace, deflects the
current of hot gases upward so as to impinge against the crown of the boiler
until they meet the water-way end 6 of the boiler against which they impinge
and then travel downwards and pass through the space underneath such water-
way end. From this point the products of combustion are led through flues
extending along the sides of the boiler to the front thereof, and then pass up-
wards to a flue which extends along the crown of the boiler to the rear thereof,
and from thence they pass to the uptake or chimney. These brickwork flues
may however be otherwise arranged if desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
1. A saddle boiler, the characteristic feature of which is the waterway bridge a,
disposed in front of the waterway check-end b, whereby the products of combustion
are deflected upwardly against the crown of the boiler, along which they pass until
they encounter the check-end, which deflects them downwards into the return
flues, substantially as herein set forth with reference to the drawings.
