Improvements in and relating to Set Boilers.
I, ALBERT EDWARD SMITH, trading as James Smith, of Bridge End Tin, Copper
and Brass Works, Burnley, in the County of Lancaster, Tin Plate Worker, do
hereby declare the nature of this invention to be as follows:-
This invention relates to set boilers heated either by gas, oil, or fuel, and con-
sists in the combination with a set boiler of a condenser for condensation of the
steam, which arises from the hot water in the boiler, and which has hitherto been
allowed to escape, either through the lid of the boiler, or by a pipe to the chimney.
By the application of my invention, the heat carried by the steam evolved from
the hot water is confined within the precincts of the boiler, and raises the temper-
ature thereof either by passing thereto with the condensed steam, or in the vapor-
ized surrounding atmosphere.
The condenser may be of any suitable construction, but it preferably consists
of a short copper tube fitted to the top of the boiler, and provided with a perforated
metal plate, for condensing the steam, and furnished with a condensing chamber,
preferably of copper, and about four to six inches in length. This chamber may
be either circular, conical, cylindrical, or of any other desirable form.
The condensed steam returns back to the boiler by the short length of pipe.

I, ALBERT EDWARD SMITH, trading as James Smith, of Bridge End Tin, Copper

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

This invention relates to what are generally known as set' boilers heated
either by gas, oil, or other fuel, and consists in the combination with a
< set" boiler
of a condenser for condensation of the steam, which arises from the hot water in
the boiler, and which has hitherto been allowed to escape either through the lid
of the boiler, or by a pipe to the chimney.
By the application of my invention, the heat carried by the steam evolved from

page_text: the hot water is confined within the precincts of the boiler, and raises the temper-
ature of the water either by passing thereinto with the condensed steam, or remain-
ing in the confined adjacent vapor.
The condenser may be of any suitable construction, but it preferably consists
of a short copper tube a fitted to the top of the boiler b (as seen on the accompany-
ing sketch of a boiler top with my invention applied thereto) and if desired pro-
vided with a perforated metal plate (not shewn on the drawing) for assisting the
condensing of the steam, and furnished with a condensing chamber c, preferably
of copper, and about four to six inches in length. This chamber c may be either
circular, conical, cylindrical as shewn, or of any other desirable form with plain,
corrugated, or indented sides and top.
The boiler is shewn with the usual loose hinged flap or top 6*. The condensed
steam or hot water returns back to the boiler 6 by the short length of pipe a, if
the latter is used; if not, the bottom of the chamber of course is open directly to
the upper part of the boiler.
Thus the water in the boiler will be more quickly heated and will retain its
heat longer than is the case when no condenser is used.
my
Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed I declare that what
I claim is-
-
"
The combination with a set boiler of a condensing chamber fitted to the top
of the boiler, and communicating with the steam space above the water therein,
substantially as and for the purposes hereinbefore described.
Dated this 2nd day of December 1898.
