Improvements in Steam Carriages.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of
18, Buckingham Street, Strand, W.C., London, Patent Agent, do hereby declare
the nature of this invention, a communication to me from abroad by François Gros,
of 57 Rue de l'Ourcq, Paris, France, Engineer, to be as follows:-
This invention consists in a steam carriage for use on roadways, in which the
furnace, boiler, and all mechanism is arranged on or within the forecarriage
and in connexion with the two fore wheels which are guiding as well as driving
wheels.
The whole of the rear carriage body can thus be left free for passengers or
goods and may be of any suitable kind.
The fore-carriage carries two rearwardly extended parallel bars which are
supported by the springs of the axle of the rear wheels.
On these bars the rear carriage body may be secured, the said body having any
desired shape and being easily removable and replaceable by another shape without
any interference with the driving machinery within the fore body.
The fore-wheels are carried in the usual way by a rotary frame and through
the pivotal centre of this frame passes a vertical shaft having at its lower end a
worm gearing with a pinion and driving the fore wheels of the vehicle through
spur gear and differential gear box of the usual construction. The connection of
spur wheels by pivoted links permits of a movement of the axle of the running
wheels in a vertical plane under the action of the supporting springs and inequalities
in the road. The shaft aforesaid is driven by bevelled gear from a crank shaft
revolved by rods of pistons in steam cylinders. The boiler with vertical water
tubes is provided with a steam super-heater; a float in the boiler governs a slide
valve and the latter is adapted when open to allow steam to pass to actuate the
feed pump so that the water level is automatically maintained in the boiler.
Petroleum is adopted for the firing and is contained in a reservoir whence it passes
to atomizers firing the boiler through holes in the furnace wall. Steam is fed to
the atomizers and to the driving cylinders by a balance which acts to reduce the
supply to the atomizers as the pressure rises and vice versa. A feed water tank and
pipe for condensing the waste steam are also provided. A pedal lever governs
the admission of steam to the cylinders and the pedal lever operates a brake on
the rear wheels.
The guiding of the vehicle is effected through a hand-wheel and gear
operating on a worm and worm-wheel on the king bolt of the rotary plate or
wheel frame.

I, REGINALD HADDAN of the Firm of Herbert Haddan & Co. of
18 Buckingham Street, Strand, W.C. London, Patent Agent do hereby declare
the nature of this invention, a communication to me from abroad by François Gros,
of 57 Rue de l'Ourcq, Paris in the Republic of France, Civil Engineer and in

page_text: matner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention consists in a steam carriage for use on roadways, in which the
furnace, boiler, and all mechanism is arranged on or within the forecarriage and
in connection with the two fore wheels which are guiding as well as driving
wheels.
The whole of the rear carriage body can thus be left free for passengers or goods
and may be of any suitable kind.
In the annexed drawing which is merely intended to illustrate the relative
arrangement of the parts one with regard to another and is not intended to show
details of construction.
Fig. 1 is a side elevation of the fore carriage and of the frame connected with
it to carry the wheels of the rear carriage. Fig. 2 shows the same with addition of
the rear carriage body.
Fig. 3 is a front elevation.
Fig. 4 is a section through the forecarriage and body in direction of the length
of the vehicle and Fig. 5 is a vertical cross section thereof, both on a larger scale
showing the disposition of the driving mechanism.
Fig. 6 is a cross section of the boiler.
The forecarriage a carries the two rearwardly extended parallel bars b which are
supported by the springs e of the axle of the rear wheels d. On these bars b the
rear carriage body e may be secured, the said body e having any desired shape and
being easily removable and replaceable by another shape without any interference
with the driving machinery within the fore body a.
The fore wheels fare carried in the usual way by a rotary frame and through
the pivotal centre of this frame passes the vertical shaft B' having at its lower
end the worm C gearing with the pinion D and driving the fore wheels through
gear E E E and differential gear box G of the usual construction. The con-
nection of wheels E, E' E' by pivoted links E, E permits of a movement of the
axle of wheels in a vertical plane under the action of the supporting springs
and inequalities in the road. The shaft B' is driven by bevel gear B B from a
crank shaft A revolved by rods of pistons in the steam cylinders A¹. H represents
a boiler with vertical water tubes K. J is the steam superheater. L is a float in
the boiler and L' a slide valve of any usual construction governed by the position
of the float, and the latter is adapted when open to allow steam to pass to actuate
any kind of feed pump (not shown) communicating with chamber R so that the
water level is automatically maintained in the boiler. Petroleum is adopted for
the firing and is contained in a reservoir Q whence it passes to suitable atomizers Q'
firing the boiler through holes T. Steam is fed to the atomizers and to the driving
cylinders A' through the distribution box M in which is a piston balanced by the
counter pressure of the steam and a spring and is connected to the levers V₁
regulating the cocks on the atomizers so as to act to reduce the supply to the
atomizers as the pressure rises and vice versa. R is the feed water tank and S the
pipe for condensing the waste steam. N is a pedal lever operating a valve
governing the admission of steam to the cylinder A' and O à lever operating
through any suitable connections a brake on the rear wheels. V represents a
jacketting of bad heat conducting material.
The guiding of the vehicle is effected through a hand wheel P and gear Y Y¹
worm X and worm wheel Z on the king bolt of the plate or frame g.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I would have it understood
the invention here is not in the details, for all the parts separately are old, and no
claim is made to any construction of the parts but I declare that what I
claim is.
1. In a steam carriage the combination with the fore body of steam generating
apparatus therein, a motor therein, a rotary frame supporting said fore body a

page_text: vertical shaft traversing the pivot of said frame and geared to said motor wheels
on said frame, and gear connecting said wheels and vertical shaft substantially as
set forth.
2. In a steam carriage the combination of a fore body, a rotary wheel frame
supporting said fore body, parallel bars connected to said fore body, a rear wheel
frame supporting said bars, a removable carriage body on said bars, a steam motor
in said fore body, a shaft traversing the pivotal axis of the rotary wheel frame under
said fore body, gear connecting said motor and shaft and gear connecting said
shaft and the wheel axle of said rotary wheel frame substantially as and for the
purpose set forth.
3. In a steam carriage the combination with the fore body of a rotary wheel
frame thereunder, a steam motor in said fore body, a shaft traversing the pivotal
axis of the said wheel frame, gear connecting said shaft and motor, gear connecting
said shaft and the axle of the wheel frame, hand wheel P and gear connecting said
hand wheel and rotary wheel frame for the movement thereof substantially as set
forth.
4. In a steam carriage the combination with a boiler, a motor adapted to be
driven by steam therefrom and atomizers adapted to supply liquid hydrocarbon for
the heating of said boiler, of a balance valve M adapted to automatically regulate
the supply of steam to said atomizers in accordance with the steam used by the
motor and the pressure prevailing in the boiler substantially as set forth.
5. In a steam carriage the combination with a boiler of a feed pump thereto, a
float L in said boiler and a valve L' directly controlled by said float and adapted
to admit steam to the feed pump when the float falls to a predetermined level.
