to be as follows:-
My invention relates to improvements in fire bars for steam generators the
object being to provide more durable fire bars which serve also as a fuel economiser.
I construct the fire bars in the form of tubes, and circulate water through
them from the boiler. The said tubes may be of any convenient section, but
are preferably elliptical..
The tubular bars are preferably so arranged as to form the bridge, and are
continued to the back of the boiler for connection either to the economiser or
direct to the boiler.
My improved bars, besides being more durable, improve the draught by pre-
venting the formation of clinker.

I, CLARENCE GLOVER, of Wortley Low Mills, Leeds, in the County of York,
Woollen Cloth Manufacturer, 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:-
My invention relates to improvements in steam generators, the object being to
provide a more durable and efficient furnace for this purpose I employ a tubular
furnace consisting of hollow or tubular grates or fire-bars.
I construct the fire-bars in the form of tubes or hollow bars, through which
water is allowed to circulate from the boiler, or through which water may be
pumped or injected to feed the boiler; the said bars may be of any convenient
shape or section, but are preferably round or elliptical.
The tubular furnace consists of a series of tubes, which have air spaces between
them and are preferably so arranged as to pass to or beyond the bridge to any
convenient distance, where they may either be connected to the boiler or be
returned over the bridge for re-connection to the front of the boiler.
My improved tubular furnace, besides adding, considerably to the durability

also considerably increases the steam raising power of the boilers to which it is
applied.
DESCRIPTION OF DRAWINGS.
Fig. 1 shows a sectional elevation of my invention as applied to an ordinary
Lancashire boiler.
Fig. 2 shows a front elevation of same partly in section.
A are the tubes which issue from a lower or inlet chamber B fixed upon the
front of the boiler. The said tubes form the fire-bars at the bottom of the furnace
of the boiler, and are preferably carried beyond the bridge C, then turned and
brought forwards again near the top of the furnace to the front of the boiler,
where they enter the arched upper or outlet chamber D).
The lower chambers B B are connected to each other and to the boiler by a
three-way inlet pipe E (or the said chambers may be supplied from a suitable
feed-water pump or injector), and the upper chambers D D have each an outlet E
to the boiler.
The fire-bars may consist throughout of my improved tubular bars, or tubular
bars may be employed in combination with solid bars, arranged alternately or
otherwise as may be desired.
My invention is equally applicable to all types of steam generators, as for
instance to the boilers of portable engines, and to marine, locomotive, Cornish,
and Lancashire boilers, the arrangement of the said fire-bars being modified
according to the type of boiler to which they are applied.
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) In steam generators, the employment of tubular fire-bars of any suitable
section, through which water is circulated from the boiler or injected to feed the
boiler, substantially as shown and described.
(2) In a Lancashire or Cornish boiler, the combination of the tubular fire-
bars A, the lower chamber or chambers B (supplied either by the inlet pipe E
from the boiler, or by a suitable feed-water pump or injector), the arched upper
chamber or chambers D, and the outlet pipe or pipes F substantially as and for the
purposes shown and described.
