PROVISIONAL SPECIFICATION.
Improvements in Fire Grates.
We, SIEGFRIED MARCUS, Engineer and Inventor, and EUGEN FERDINAND
BOTHE, Mechanic, both of 37 Mariahilfer Strasse, in the City of Vienna, in the
Ere of Austria, do hereby declare the nature of our invention for "IMPROVE--
MENTS IN FIRE GRATES," to be as follows:-
This invention relates to improvements in fire grates the object of the same being
to prevent all slacking of the grate, to keep the interstices free and thus permit
the unhindered passage of air to the fuel on said grate. This construction of grate
can be readily applied to all kinds of furnaces and the like, and offers the great
advantage that a better combustion of the fuel and consequently a higher
utilization of the same is attained.
In carrying out our said invention a group of thin rails is arranged under the
grate beneath the interstices of the latter which rails we term the grate comb,.
which when not in use lies beneath the bars of the grate.
This grate comb or cleaner may be arranged at an incline to the fire bars, so.
that the same can be moved through the interstices of the grate by means of a
suitable device such as a lever whereby the rails of the comb will not only pass
through the interstices of the fire bars, but can penetrate a desired distance into
the fuel. The distance to which the comb can penetrate the fuel is limited by
means of a stop or by a pin or peg.
It will be evident that when this so called comb is operated from time to time,
all slacking or clogging of the grate will be prevented and that the combustion of
the fuel will be more economical and smokeless in consequence of the free passage.
of atmospheric air, and forms a substitute for the troublesome stocking of the fuel
or scraping out the fire bars with a scraper as now customary.
It will be evident that the form of the grate and also the arrangement of the:
grate can be modified to suit the requirements of the case.

Improvements in Fire Grates.
We, SIEGFRIED MARCUS, Engineer and Inventor, 37 Mariahilfer Strasse,.
Vienna, Austria, and EUGEN FERDINAND BOTHE, Mechanic, 37 Mariahilfer
Strasse, Vienna, Austria, 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 :-
This invention relates to improvements in grate cleaners, the object of the same
being to prevent all slacking of the grate, to keep the interstices free, and thus
permit the unhindered passage of air to the fuel on said grate.
This construction
of grate with a device for cleaning same can be readily applied to all kinds of
furnaces and the like, and offers the great advantage that a better combustion of
the fuel, and consequently a higher utilization of the same is attained.
In the accompanying drawing
Fig. 1 is a top view, Fig. 2 a side view, Fig. 3 is a cross section of the grate with
the cleaning device, and
Fig. 4 a perspective view of the reverse grate.

page_text: As will be seen by the accompanying drawing, a group of thin rails (a, a', a²,
a³, a, a,) beneath the interstices of the latter, and which we term the grate
comb (B) which, when not in use, lies beneath the bars of the grate (Fig. 2).
Figure 2 represents our grate comb or cleaner B, arranged at an incline to the
fire bars, in such manner, that the same can be moved through the interstices of
the grate by means of a suitable device, or, as shown in Fig. 2, by means of a
lever b, whereby the rails of the comb will not only pass through the interstices of
the fire bars, but can penetrate a desired distance into the fuel.
The distance to which the comb can penetrate the fuel is limited by means of a
stop, or as represented in Figs. 2 & 3 by a pin or peg c.
It will be evident that when this so called comb is operated from time to time,
all slacking or clogging of the grate will be prevented and that the combustion of
the fuel will be more economical and smokeless in consequence of the free passage
of atmospheric air, and forms a substitute for the troublesome stoking of the fuel
or scraping out of the fire bars with a scraper, as now customary.
It will be evident that the form of the device for cleaning the grate corresponds
to the form and size of the latter, which varies according to the different purposes
and requirements for which the grate is employed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
An improved grate cleaning device for grates of any description and consisting
of a grate comb (B) formed of a number of rails (a, a', a², etc.) connected together
so as to correspond with the interstices between the fire bars, and adapted to be
operated by a lever (b) or other suitable device in order to free said interstices
from slag, and penetrate into the fuel on the grate for admitting air to such fuel,
substantially as described in the Specification and shown in the drawings.
