PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Vehicles.
A communication from the Firm H. W. VON DER LINDE, of Crefeld, Germany,
Chemical Manufacturers.
I, WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields in the County of
London, Consulting Engineer, and Chartered Patent Agent, do hereby declare the
nature of this invention to be as follows:-
This invention has reference to improvements in apparatus for heating
vehicles such as broughams, tramcars and the like the objects being to provide
apparatus requiring but little attention, and to enable the heating to be
economically effected without any unpleasant fumes or vapor being allowed to
enter the vehicle.
For this purpose there is arranged beneath one or more of the seats of th.
vehicle to be heated a light cast-iron or sheet-iron box, capable of being closed air-
tight and provided with a removable grate, upon which fuel preferably in the form
of briquettes is burnt, the entry and exit of air being provided for by means of
pipes.
Specially prepared wood charcoal briquettes capable of being broken into pieces
and which burn without giving off smell are by preference used.
In the accompanying drawings,
Fig. 1 shows an elevation of the body of a brougham having heating apparatus
constructed according to this invention arranged beneath the front seat; and
Fig. 1 shows a cross section of the same.
Fig. 2 shows an elevation of a tramcar having heating apparatus adapted to take
three briquettes arranged beneath the seat between the wheel-cases.
Fig. 3 shows a front elevation of heating apparatus which is closed air-tight by
means of a cover screwed on to the front:
Fig. 4 shows a side-view of the same; and
Fig. 5 shows a front view thereof with the cover removed.
In all the figs. similar reference letters denote corresponding parts.
The heating box H which is made of cast-iron, or if desired-for example for
tramcars of sheet-metal, contains a loose grate c (Fig. 5) and receives the air
supply necessary to support the combustion of the fuel either by means of the
vertical tube a (Fig. 2) passing through the bottom of the vehicle or of the
tubes a, a, a² (Figs. 1, 14, 3, 4 and 5). The two air outlet tubes in the example
illustrated in Figs. 1 and 14 pass under the seat through the rear wall of the
vehicle, and in the example illustrated in Fig. 2 are conducted along the walls and
through the roof. Such apparatus is used as follows:-
The grate is removed from the box, the briquette or briquettes is or are placed
upon it and ignited. Then the grate with the burning briquette or briquettes is
slidden into the box and the latter closed air-tight by means of the cover, which
may be provided with square headed screw-bolts that screw into holes formed in
the box, a specially formed key F shewn in dotted lines in Fig. 4 being provided
For turning said screw bolts. In consequence of the circulation of air through the
tubes a a' a', the box, and the tubes b, a uniform and gradual combustion then takes
place.
The heating apparatus is particularly economical as the briquettes employed are

page_text: very cheap and burn a fairly long time, say about 8 or 9 hours, without attention
or the necessity of any addition of fuel.

Improvements in Apparatus for Heating Vehicles.
A communication from the Firm H. W. VON DER LINDE, of Crefeld, Germany,
Chemical Manufacturers.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Chartered Patent Agent, 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 has reference to improvements in apparatus for heating
vehicles such as broughams, tram-cars and the like the objects being to provide
apparatus requiring but little attention, and to enable the heating to be:
economically effected without any unpleasant fumes or vapour being allowed to
enter the vehicle.
For this purpose there is arranged beneath one or more of the seats of the
vehicle to be beated a light cast-iron or sheet-iron box capable of being closed air-
tight and provided with a removable grate upon which fuel preferably in the form
of briquettes can be burnt, the entry and exit of air being provided for by means
of pipes.
The specially prepared wood charcoal briquettes which are capable of being
broken into pieces and which burn without giving off smell are by preference used.
In the drawings filed with my Provisional Specification,
Fig. 1 shows in elevation the body of a brougham with heating apparatus
constructed according to this invention arranged beneath the front seat therein;
and
Fig. 1 is a cross-section thereof.
Fig. 2 shows in elevation a tramcar with heating apparatus arranged beneath
the car seat between the wheel-cases and adapted to burn three briquettes at
a time.
Figs. 3 and 4 are front and end elevations to a larger scale showing the heating-
apparatus detached and closed air-tight by means of a cover screwed on to its
front side.
Fig. 5 is a similar view to Fig. 1 but with the front cover removed.
The heating-box H, which may be made of cast-iron, or if desired-for example
for tramcars of sheet-metal, contains a loose grate c (Fig. 5) and receives the air-
supply necessary to support the combustion of the fuel either by means of the
vertical tube a (Fig. 2) passing through the bottom of the vehicle or of the
tubes a, a, a² (Figs. 1, 1, 3, 4, and 5). The two cutlet tubes in the example
illustrated in Figs. 1 and 14 pass under the seat and through the rear wall of the
vehicle, and in the example illustrated in Fig. 2 are conducted along the walls
through the roof.
Such apparatus is used as follows:-
The grate is removed from the box, and the briquette or briquettes is or are
placed upon it and ignited. Then the grate with the burning briquette or
briquettes is slidden into the box and the latter closed air-tight by means of the
cover, which may be provided with square headed set screws that screw into holes
formed in the box, a specially formed key F, as shewu in dotted lines in Fig. 4,

page_text: being provided for turning said set screws. In consequence of the circulation of
air through the tubes a a' a², the box, and the tubes b, a uniform and gradual
combustion then takes place.
The heating apparatus is particularly economical as the briquettes employed are
very cheap and burn a fairly long time, say about 8 or 9 hours, without attention.
and without the addition of any other fuel.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
An apparatus for heating vehicles such as carriages and tramcars, in which the
combustion of the fuel takes place on a removable grate c surrounded by a heating
box H capable of being closed air-tight, and in which the circulation of air and hot
gases is effected by one or more inlet tubes a entering at the bottom of the heating-
box, and outlet tubes 6 leaving at the top of the said box whereby the combustion
of the fuel and the heating of the vehicle is effected with very little attention and
without liability of unpleasant fumes or vapor entering the vehicle substantially as
described and shown.
