Improvements in or relating to the Method of Stoking Furnaces, and
in Appliances for Effecting the same.
I, JOSEF LEOPOLD, of Kladno, in the Kingdom of Bohemia, in the Austrian
Empire, Engineer, do hereby declare the nature of my said invention and in what
manner the same 18 to be performed, to be particularly described and ascertained
in and by the following statement:―
My invention relates to the operation of stoking furnaces supplied with solid
fuel, and its object is to facilitate such operations by providing means whereby the
frequency of opening the fire doors and admitting cold air to the furnaces is
greatly reduced.
According to my invention I provide an opening in the fire door through which
the 1od used in stoking may be introduced, and the fuel stred and mampulated
without opening the door, other openings fitted with slabs of mica being provided
for viewing the state of the fui nace
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.

and the like

a a are fui nace doors baie doors, the frames of which are fitted with slabs
or plates of mica b' to enable the stoker to examine the state of the fire without
opening the fire door a
a 18 the stoking rod which passes through a conical
aperture d in the fire door.
In some cases I fit the rod c in a globular bearing g, as shown in Fig 4, the
bearing being held to the door by the plate h. Slots s (Fig 1) and s (Fig. 5) are
formed in the door a, extending from the edge of the door to the normal position
required for the rod c. Sliding covers e e¹ are fitted to these slots, the covers being
notched to receive the rod c A fork(Fig 1) may be added to lock the rod in
position. The rod c and sliding covera e e¹ may be moved towards the edge of the
door to accommodate the removal of the rod to other suitable positions, as required
Instead of the sliding bars e el, a hinged door p (Figs. 7 and 8) may be fitted
to the door a. The door is locked by the pivoted bar k, which is formed with a
notch for the passage of the rod c, the door p being amilarly notched for the same
purpose
In Figs. 9 and 10 is shown a similar fall down door g, fitted with a roller r to
support the rod o and reduce friction. This door g, 18 locked by the bar ¹ pivoted

by the bar, the door q, being readily looked by the end, and unlocked by its
removal.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I wish it to be understood
that I do not confine myself to the exact details above described, as the same may
be varied without departing from the nature of my invention, and I declare that
what I claim is;-
1. The improved method of stoking furnaces substantially as and for the purposes
described.
2. The improved construction of the fire doors of furnaces whereby the rod o may
be introduced into the furnace and manipulated without opening the door of the
furnace substantially as herein before described and illustrated by the drawings
3. In combination with furnace doors constructed as aforesaid, the application
and use of doors b fitted with transparent material for examining the state of the
fire, substantially as described
