WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the County of
Middlesex. "IMPROVEMENTS IN AND CONNECTED WITH LOCOMOTIVE ENGINES."
(A communication from abroad by Albert Focke, of the Firm Louis Reichel and
Company, of Cöthen, Anhalt, Germany.)
.
This Invention has reference to the automatic feeding of fuel to the furnaces of loco-
motive engines and the prevention of the escape of sparks from the chimneys thereof.
For feeding fuel apertures are formed through the front of the fire box leading
into the interior of the same just above the fire grate. There may be one or more
such apertures according to circumstances. Each aperture is provided with a barrel
in which works a plunger actuated by a connecting rod from an eccentric fixed on
the front axle of the tender. In front of the apertures and close above each of the
barrels is a trough or hopper, in which is placed the fuel to be fed on to the grate.
That part of the barrel immediately below the bottom of the trough or hopper is
open at top, so that the fuel may drop freely from the trough or hopper into the
barrel in such manner that when the plungers are actuated fuel will be forced by
them through the apertures on to the fire grate.
There is a fire door as usual for the examining and stirring the fire, et cætera.
The fire grate is inclined upwards towards the front end of the engine.

page_text: In-Figs-1-and-2 of the accompanying Sheet of Drawings a, a', are two eccentrics
firmly keyed on the front axle b of the tender and working-by means of straps and
rods two plungers c and c¹, which work in the barrels d, ', to which water is led
through two pipes provided with cocks. e, e, are hoppers provided with gratings
of round rod iron, which-prevent-pieces of fuel of too large a size coming in contact
with the plungers. The fuel is broken up by the fireman until it can fall through
the gratings.
To prevent the escape of sparks there is fixed centrally within the chimney a
conical-tube, with its large end extending down just into the blast pipe, and its
small end reaching about half way up the chimney. Above this conical tubo is
fixed another and shorter tube of the form of an inverted truncated cone, above
the mouth of which is fixed a metal disc or baffle plate. Part of the exhaust steam
issuing from the blast pipe passes up through the lower conical tube into the upper
one, and is by the disc deflected outwards and downwards into the annular space
between the tube and chimney. Sparks carried up the annular space by the exhaust
steam from the blast pipe are met by the counter current from between the upper
edge of the inverted conical tube and the disc, and are extinguished.
In Fig. 3 of the Drawings (which is to a larger scale than Figs. 1 and 2) f is the
lower conical tube; g, the upper conical tube; h, the disc or baffle plate; i, the
chimney.
The arrows indicate the direction of the current issuing between the upper conical
tube and the disc or baffle plate.
