page_text: I, HENRI VALLEE, Constructor, of 60, Rue de l'Australie, Mans, in the Republic
of France, do hereby declare the nature of this invention to be as follows:
:-
This car is formed firstly by a frame of steel tubes cold drawn without brazed
joints, secondly by a fore-carriage with jointed parallelogram.
The steering levers are attached on ball sockets by means of a triangle or cross-
piece and of two links suitably inclined towards the axis of the vehicle, in such.
manner as to suppress the scraping of the wheels in turning.
The fore-carriage can make a rotating movement about its points in the vertical
plane.
Thirdly the wheels: which enable broken spokes to be easily replaced comprise
a tapped rim rivetted on the felloe, which receives a nut in which is adjusted the
head of the spoke. At the nave, the spoke also receives a nut.
Fourthly, the naves are formed as follows: On the axle tree of the wheels are
fitted two rings provided with grooves to receive the balls. In the nave properly
so called, two roller sockets are forced, into which the ball rings enter without play.
Leather washers bear the end friction, and form a joint to the ball box, filled
with oil. A washer is fitted on a square to avoid its being rotated.
Fifthly. The alterations of speed are effected by friction. For this purpose two.
step cones, having any desired number of speeds and covered with leather to obtain
perfect adherence, are keyed on the spindle of the motor or on that carrying the
small pinions and the differential gearing.
In front of each step on the cones are placed rollers also covered with leather and
having a diameter greater than the space existing between the cones; these rollers
may be forced between the cones by a number of buttons or pedals equal to that of
the speeds to be obtained, the pedals are arranged on the carriage in proximity to
the feet. Any system of return movement enables one or the other of the rollers to
be engaged as desired by simply pressing on the corresponding pedal, A return
spring automatically disengages the roller as soon as the pressure on the pedal is
relieved. For the backward movement I arrange on the small speed and in-
dependently, of the driving roller, two similar rollers but of a smaller diameter,
which permit of a backward travel.
Sixthly. The motor, which is of the two equal cylinder four stroke cycle type,
comprises a compression chamber attached to the bottom of the cylinders. It is
ignited by electricity.
The admission of carburetted and of pure air takes place in a special chamber
by means of bronze discs rotating about two axes situated in the same prolonged
line. These discs are bored with holes and pass over two surfaces bored with holes
of the same diameter, and are pressed on these surfaces by a suitable spring.
The cylinders are insulated from the compression chamber by a thick joint of
asbestos. Each fly wheel is provided with four openings with wings which circu-
late the air when working. A plate fixed on the motor constitutes with the fly.

Autocar with Special Petroleum Motor.
I, HENRI VALLÉE, Constructor, of 60, Rue de l'Australie, Mans, in the Republic
of France, do hereby declare the nature of this invention, and in what manner the 1
same is to be performed to be particularly described and ascertained, in and by
the following statement; -
This invention has for its object a new type of autocar and a new petroleum
motor, specially designed to actuate it.
These carriages present the following particulars :
".
The frame is in steel tubes cold drawn without brazed joints. It is formed of
two similar longitudinal tubes stayed by perpendicular or inclined tubes which
make a perfect rigid structure. The tubes are all joined together by sockets
similar to those of cycles.
II. FORE-CARRIAGE..
Fig. 1 is a sectional side elevation of the fore-carriage, Fig. 2 is a part front eleva-
tion of the same. Fig. 3 is a half plan view of the same.
The fore-carriage is formed in front of two uprights and of a rigid crosspiece A
which connects them together, this rigid part is connected to the frame B by pieces
jointed or pivotted on crank-pins so as to be enabled to oscillate in all directions,
as will hereafter be described.
The crosspiece A is maintained near both of its ends between two plates A¹
fixed upon crank-pins A2 around which they can ascillate. The crank-pins A
are formed at a and a¹ with pivotal heads around which are freely jointed
levers A3 A4. The upper lever A³ is arranged on an axis or fixed point a² on the
carriage frame, the lower lever A which is also arranged on a pivot a³, has a pro-
longation at the back suspended at its free end, by means of a strong suspension
spring supported from the frame and having for its object to prevent vibration
or shocks and to return the lower lever A into its normal position.
By this disposal of fore-carriage with pivoted parallelogram all possible shocks
to the frame of the carriage and consequently to the travellers are prevented.
It is seen by the arrangement shown on Fig. 1 that the fore-carriage can execute
a rotative movement around its joints, in a vertical plane. As the two lateral
or parallelogram parts, are independent, one of the wheels can therefore ascend
an obstacle without the other following its movement and without oscillating the
frame.
:

page_text: VI. MOTORS, (Figs. 8, 9).
The motor has two equal cylinders connected to cranks at 180°. This arrange-
ment suppresses, shocks and renders the rotation more regular and even.
The mechanism of the motor, the frame, cylinders, and compression chamber
are in the same axis and the dimensions are reduced to assure a minimum of space
and weight for a given force..
.:
The cycle is a four stroke cycle, with two successive explosions, that is, a complete
cycle with four strokes. The utilised product is the ordinary commercial volatile
oil. The speed varies between 200 to 500 revolutions. The compression and
ignition are effected in a compression chamber attached and bolted on to the
bottoms of the cylinders.
The ignition is electrical, by means of a battery and of a Ruhmkorff coil. ...
This ignition can also be effected by means of incandescent tubes.
The admission of carburetted and of pure air takes place in a special chamber,
through bronze discs rotating about two axes co-axial (see Figs. 7, 8, 9). These
discs bored with holes of a convenient diameter, work on two surfaces bored with
holes of the same diameter, and are pressed on these surfaces by a spring. In setting
in different ways the holes of the discs in relation to those of the surfaces or seats,
the richness of the explosive mixture and the quantity of this mixture introduced
in the cylinders can be varied at pleasure. The discs may be set in many ways,
for example, by cranks i and levers placed on the carriage, near the conductor.
This chamber is not so heavy or so cumbersome as cocks or tubes.
This explosive mixture goes from the box h into the cylinders, passing by the
admission pipes h Figs. 7, 8, 9.
The exhaust of burnt gases is effected by the lower and lateral outlets 7.
The heated parts of the motor and especially of the cylinders, are cooled by
means of a simple circulation of air, in the following manner:
1. The cylinders and the compression chamber are insulated from one another
by means of a joint of asbestos of great thickness. The object to be attained is to
specially cool the cylinders, in view of the oiling and wear of the segments. Now,
it is clear that the highest temperature is in the compression chamber and that it
´is much higher than that which the explosive mixture communicates by itself to
the cylinders. Therefore, the compression chamber, is greatly heated and heats
the cylinders by conductibility. By insulating the explosion chamber the heating
of the cylinders is diminished. That is the object of the joint of asbestos.
2. Each fly-wheel has four openings C which are provided with wings C¹ curved
and presenting their concavity in the direction of rotation of the fly-wheel, and
which gather the air during the working of the motor. A plate of sheet-iron C³
fixed on the motor by any process, constitutes with the rim of the fly-wheel a con-
duit in which the air circulates at a great speed. The frame and the cylinder
carry laterally for the outlet of this air two openings C. The cylinders and the
compression chamber carry small ribs or wings D, representing a great cooling
surface, the base of the cylinders and of the compression chamber are hollowed
between these small wings so as to let the current of air circulate between them.
This current passes over all the surface of the cylinders and of the compression
chamber; a covering of sheet iron D¹ surrounding the whole, assures the passage
on the parts to be cooled. The air escapes at the back by two openings situated
just opposite the exhaust valves which are thus in the full cooling current.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:
1. In an autocar with special petroleum motor: the combination of a frame in
steel tubes cold drawn without brazed joints, with a fore-carriage with parallelo-
gram and being able to take great inclinations.

page_text: 2. The combination of a frame and fore-carriage already claimed with wheels
with spokes easily interchangeable, and dust proof hubs having the advantages
of the leather packed hub and of the ball hub.
3. The combination of the body of a carriage as above claimed with a friction
speed by means of cones, stepped or not, between which rollers can be forced by
the foot.
4. The combination of an autocar as above, with a two cylinder balanced motor
suppressing the vibration, of which the frame, the cylinders, and the compression
chamber are disposed in the same axis; the admission of exploding gases being
effected by juxtaposited discs pierced with holes whose positions can be varied,
the fly wheel being provided with openings having small vanes giving a great
cooling air current around the mechanism susceptible of being heated.
