PHILIP SYNG JUSTICE, of No. 27, Southampton Buildings, Chancery Lane, in the
County of Middlesex, Engineer. "IMPROVEMENTS IN APPARATUS FOR EXTIN-
GUISHING BURNING SPARKS AND CINDERS, WHICH INVENTION IS ALSO APPLICABLE
THE CONDENSING OF THE EXHAUST STEAM FROM PORTABLE AND OTHER
ENGINES."
TO
This Invention consists of apparatus by which the live or burning sparks and
cinders usually ejected from the smoke funnel of steam engines when at work may
be extinguished, and made to fall outside the funnel, and is also applicable for con-
densing the volume of exhaust steam into water as it passes from the mouth of the
smoke funnel, thereby overcoming one of the objections to the use of steam engines
on the tramways and public roads.
A tubular hoop properly pierced with small orifices is attached to the rim or
mouth of the smoke funnel, said hoop being connected by a small pipe with the
steam chamber or the exhaust of the steam engine, by which a constant pressure
of steain is maintained within the said tubular hoop, and issuing thence through
the small orifices extinguishes the sparks as they rise from and fall outside of the
mouth of the smoke funnel
To still more effectually complete the extinguishment of said sparks a peculiarly
curved or other suitable shaped " cowl" or "cap" is attached above the inouth of
the funnel, the lower portion or rim extending around and below the rim of the
smoke funnel at a sufficient distance from it to avoid choking the draught of the
engine. The rim of said "cowl" has in like manner to the smoke funnel a tubular
hoop pierced with small holes for the egress of steam supplied in same way as to
the smoke funnel hoop. When the live cinders and sparks are thrown through the
mouth of the funnel they first meet with the numerous small jets of steam from the
hoop surrounding its rim, which tend to increase the draught, and after striking the
properly curved or other suitably shaped " cowl
or "cap" are deflected towards
the rim of the "cowl," from which additional small jets of steam are issuing, when
they are at once precipitated into a water and cinder box surrounding the upper
part of the smoke funnel, in which may be placed pans of water, if needed, to
complete the extinguishing of the larger cinders. This cinder and water box may
be divided into sections, and by having its outer walls hinged the water pans may

therein, as needed.
By supplying similarly placed tubular hoops with cold water instead of steam
and under sufficient pressure from the pump or other arrangement, and having the
apertures in the hoops properly pierced so that the water issuing from them
and the condensed steam will not again fall into the smoke funnel and become
vaporized, the volume of exhaust steam will be condensed in passing the water
spray, and fall into the water pans, from whence it may be carried off either to the
tank of the engine after filtering or to any convenient place. This plan will also
effect a perfect extinguishinent of the sparks if the water be either cold or hot; and
if used for a spark extinguisher only the hot water of the boiler will supply the
requisite pressure without the aid of the pump.
