page_text: Improved Magazine Stove.
I, ROBERT WINTER, of 42, Burgstrasse, Hanover, Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements made in magazine-stoves and
the special object contemplated by this invention is a feeding hopper arranged
at the top of the stove.
A further object of this invention is a vertical grating arranged at the rear
part of the stove, within the latter and in front of the gas outlet-hole.
A still further improved arrangement of the magazine-stove, forming the
object of the present invention, consists in an inner jacket formed of perforated
and tubular kiln-bricks placed all around of the fire-room except on the side of
the vertical grating.
Another arrangement consists in the fire-gas collector at the top and all around
of the stove.
The first mentioned feeding-hopper, for the introduction of the fuel is hung
on a packing or shoulder formed in the upper wall of the top part of the magazine
stove and rests at the same time, with its lower edge upon the upper edge of the
vertical grating to hold the latter. This feeding-hopper is closed by a movable
cover, tightening the said hopper and closing the stove hermetically. The cover
turns on hinges arranged at the back part thereof and the front part of this
cover has a small pivoted lever, extending downwardly and provided with a pad
to apply on a small air-admission-hole, bored in the curved wall of the top-part
of the stove, and to close this hole. The said lever carries another small lever
provided with a hook at one end and which, when lowered engages with a pro-
jecting border of the air-admission-hole to close the latter and to secure the closure
of the cover of the feeding-hopper. The last mentioned lever being disengaged
from the projecting border and withdrawn, the other lever is lifted, whereby
the air-admission-hole is first opened and the cover of the feeding-hopper after-
wards. All these movements are done by one sole operation and very quickly.
The fire-gas collector of the improved magazine-stove is arranged at the top
and the rear part of the stove. The gases coming from the fire-room flow into
the upper collector formed by the annular space all around of the feeding hopper
and thence, these gases are led downwardly through a descending passage forming
the back collector of the stove. This back collector is provided with a hole at
the upper part thereof through which enters air mixing with the gases to burn
these latter in front of the gas outlet pipe, arranged at the lower part of the back
collector.
In order to cause the fire-gases to flow off very quickly from the fire-room,
this fire-room is formed, on one hand by a vertical grating at the back part, and
on the other hand by a circular jacket, formed of kiln-bricks provided with tubular
passages, discharging in an annular space, leading to the fire-gas collector.
By this arrangement, it will he seen that the gases produced by the combustion
of the fuel, remain no longer in the combustion room, thus ensuring a normal

without producing any smoke, which is a very important point never found with
other ordinary stoves.

I, ROBERT WINTER, of 42, Burgstrasse, Hanover, in the Empire of Germany,
Manufacturer, 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:-
My invention relates to an improved magazine stove.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig's. 1, and 2, are vertical sections.
Fig. , is a transverse section.
Fig's. 4, 5, 6, 7, and 8, are sectional détails drawn to an enlarged scale.
Fig's. 7, and 8. The cover 1) is connected by means of the hinge U-S', to the
crown or arch R and has at the extremity opposite to this hinge, two lugs V,
to which is jointed the little cover 11 by means of the lug W. This cover Di
which serves the purpose of closing the air admission opening, is provided with
two lugs X, to which is jointed or articulated the lever or the handle d', the
lower extremity d of which can engage with a projecting rib on the projection r
of the crown or arch R which serves to retain that extremity when the said
lever is lowered. When the cover D is closed, the projections with which
it is provided, maintain the hopper T upon the edge R of the arch or crown R.
To these improvements belongs the special application of the feed hopper T,
which serves to charge the stove from above and at the same time to permit the
gases which escape from the receiver or chamber to accumulate in the upper
part of the stove. This hopper is suspended from a flange R° of the crown or
upper arch of the stove and tightened upon R° by the cover ]). In order to
effect this latter purpose, the cover is provided with a hinge 1° which maintains
it in place, and opposite to 10° is situated a pivoted lever D¹, having plug
adapted to hermetically close an aperture r formed in the crown or arch R for the
admission of air, and which should be opened before the opening of the cover D.
In connection with the lever D) is provided another lever, pivotally secured
to the former and which, when it is lowered, engages through its hooked por-
tion behind a projecting ledge or catch and thus secures the closure of the
aperture or hole r, the cover D and the feed hopper T tightened upon the
flange R° of the crown or arch by the flange of the cover.
In order that the rising or upright grate F° hereinafter mentioned may be
likewise fixed or held in place, the lower portion of the feed hopper is arranged
to bear upon the upper edge of the grate. When the lever is raised to dis-
engage the hook d thereof and then farther raised the lever D¹ rises so as to open
the hole or aperture and lastly the cover D, all these movements being effected
This is the
by a single operation of the hand or a single upward movement.
more important from the fact that any mistake is thus rendered impossible.
Moreover this tightening or securing of the hopper of the cover, and of the grate

page_text: is a matter of the greatest importance for the transportation of the stoves to
any considerable distance.
Another improvement applied to this magazine stove consists in the formation
of a common chamber or collector for the gases which are given off from the
receiver or container. As a matter of fact it is especially important in magazine
stoves to remove the gases as quickly as possible from the receiver or container.
For this purpose a chamber or collector S° is arranged above the receiver or
container for the gases which rise, and at the side or the discharge pipe A is
situated the rising or upright grate F which is provided with large escape or
vent holes through which the largest possible quantity of gas which may be
given off lower down in the receiver or container will be able to gain access to
the rear part of the collector S. This latter commences at the height of the
zone of combustion properly so called, and opens at the top into the chamber S°
which latter surrounds the hopper T. The fresh or outside air penetrates into
the chamber S at M and mixes with the gases which are contained in this latter
and which burn below, in front of, as well as above the discharge pipe A.
As however the gases, which are given off in the receiver or container F in the
front part of it, and especially at its circumference, are not able to pass through
the entire mass of the combustible material or fuel contained in the receiver or
container in order to reach the chamber S, an annular space G is provided round
the stove, which annular space or flue is formed of bricks composed of some suit-
able refractory material, and provided with escape or vent holes passages or con-
duits of such a shape that they will not become stopped up by the combustible
material or fuel and will allow free passage to the gases.
At different heights in these escape passages or conduits in the bricks are pro-
vided slots or slits, to admit of the gases gaining easy access to the annular
space G, and from thence, as much from above as from the side, into the collector
S, into which opens from both sides the said annular space G, as is shown in
Fig. 3.
Fig's. 4, to 6, show one form of construction for the bricks to form the annular
space G. This latter is bordered at the exterior by smooth faced annular refrac-
tory bricks B, which are situated against the casing of the stove, whilst at the
interior are placed the bricks C with the passages or conduits C¹ for the escape
of the gas, which the slits or slots C° conduct into the space G. In order to allow
of the bricks supporting themselves or resting against each other, they are pro-
vided with little tenons or projections c, with which they are either so placed as
to rest flat against the bricks B, or to enter into recesses provided in these latter
as is shown in Fig's. 4, to 6. These tenons or pins do not impede the flow of the
gases passing from below in an upward direction, or laterally towards the collec-
tor S, but provide for the interior lining an excellent support.
From the preceeding it will be evident that this arrangement of bricks, the
passages or conduits in which for the escape of the gas may be of any other
suitable form, will cause the gases in the front part and in the circumference of
the receiver or container to pass directly and without experiencing any resistance
to the collector S, where they become mixed with the air and can burn with the
lowest possible minimum of smoke, which is not the case with the arrangements
of stoves hitherto known.
The arrangement for closure mentioned in the first place, and the arrangement
described of an annular space G and of a collector S° and above all things of S,
impart to this new stove the greatest value.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: —
1. A magazine stove with upper or top feed, characterized by the fact that from
the receiver or container F of the stove the gases arrive or are delivered partly
directly, that is to say upwardly or towards the top or laterally by a rising or

page_text: upright grate Fo, partly indirectly through slots or slits Co, which are provided
in the passages or conduits C', for the escape of gas, of the lining of refractory
bricks C, and which open into the annular space G in the collectors S° and S,
in order to burn in S mixed with fresh air, before their escape into the chimney.
2. In a stove such as that characterized in the first claim, the tightening or
screwing of the feed hopper T upon the interior edge R° of the crown or upper
arch of the stove by means of the rim or flange of the cover D, and of the
rising or upright grate Fo, by the lower edge of the hopper T by means of a
fastening device in two parts D', ', the part D' of which serves to close the air
admission hole or aperturer in the crown or upper arch R, whilst the other part
engages through its hooked portion & behind the protecting edge or catch r
of the crown or arch and thus fixes or secures the cover in position, the hopper
and the grate.
3. In a stove such as that characterized in the first claim, the arrangement
of refractory bricks C which rest through tenons or pins against smooth
surfaced bricks B, or held in recesses in these latter, and in the flutings or ways
or passages C (having the form shown in Fig. 6, of the drawing) of which prevent
by the contraction of their front portions or orifices the entrance into them of
the combustible or fuel, and having slits or slots C° for the passage of the gas
which accumulates in C into or towards the annular space G of the stove, sub-
stantially as hercinabove described and illustrated in the accompanying drawing.
