I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, as communicated to me by Louis
Lockert, Engineer, Victor d'Alten, Engineer, and Charles de l'laten, Landed
Proprietor, all of 26, Place Dauphine, Paris, France, to be particularly described
and ascertained in and by the following statement:―
This invention relates to a rotary motor with equilibrated multiple explosions.
In the accompanying drawings Fig. 1 is a transverse section of our motor
perpendicular to the axis,
Fig. 2 a longitudinal section through O_X, and
Fig. 3 a longitudinal section through O Y.
The machine is composed substantially:-
1. Of a fixed circular space formed by two parallel cylinders A and B, con-
nected together by two bottom plates and f, so as to form a closed vessel.
2. Of a motor arrangement rotating in the interior of the latter, composed of
two flat crowns" joined together by two pallets P and P¹ diametrically opposite
to one another.

One of the crowns C forms part with a hub p fixed to the shaft O, which
rotates in bearings 6 b₁ cast in one piece with the cylinder B and carries two fly
wheels V and v. Two drums D and D¹ diametrically opposite to one another,
contain two cylindrical closing contrivances d and mounted on two
axes o and o¹ which emerge from the plate F through two sockets such as a, cast
in one piece with this plate.
To the axes o and o¹ two pinions e e¹ are fixed. These pinions are made of
pressed raw hide. They engage with a bronze wheel E mounted on the shaft ().
The axes o o have two rotary motions in a direction contrary to that of O, and
a double angular speed, which are communicated to the closing contrivances d
and . These are grooved according to two indentations or recesses, the out-
lines of which are combined with those of the pallets P and P¹, so that the latter
move freely, in consequence of the continuous movement of the closing con-
trivances around their axes o o¹ across the drums D D without ever coming into
contact with one another or with any part of the closing contrivances d and d¹.
The rotary motion is such that, as soon as the pallets P and PI leave the
drums D and D¹, the closing contrivances d and close the circular channel
behind them, so that they can draw in the detonating mixture for the explosion.
The position of the indentations and pallets is indicated by dots. The suction
is effected by the action of valves S and S', which are opened at the desired
moment by the cams such as r, attached to the fly wheel V.

page_text: Whilst the suction is proceeding, over an angular space which depends on the
circular length of the cam r, the closing contrivances & and d¹ continue to rotate
and the junction between their outer walls and the internal walls of the
drums D and D¹ is extended and becomes sufficient for the explosion to produce
its full serviceable effect.
I
This explosion results from the closing of the valve, which is effected by the
action of the spring R, when the cam r has passed; each of these valves has a
continuous rotary motion produced by a cord which passes over the two grooved
pulleys G and g. The effect of this continuous rotary motion is to keep the
valve S and its seat s constantly ground (smooth); it creates further, a tangential
component known by the name of tacking motion (louvoyant) which assists and
renders very easy the reciprocating movements for opening and closing, under
the action of the cam r and of the spring R (Fig. 3 shows one valve only of the
two valves S and S₁ diametrically opposite to one another; the same process
goes on simultaneously in regard to the valve S¹).
Under the action of the spring R, the valve S first closes the orifice H through
which the detonating mixture passes behind the pallet, at the same time as
the core n penetrates into the cylinder N, in communication by a lateral conduit
with the source of the explosive mixture; a certain quantity of this latter is thus
confined between S and s and is forced back into a semicircular pocket I, whence
it soon escapes, the valve being completely closed by the conduits h, passing on
to the igniter I, uncovered by the valve, the closing position of which is shown
by dots.
The igniter I is a platinum spring igniting pellet on the end of a small platinum
tube which latter conducts a hydrocarburatted mixture from the exterior of the
motor to the platinum cap I & thus brings the latter to a heat sufficient to
produce the ignition of the explosive mixture. The explosive mixture ignites on
its way and causes fire to appear behind the pallet by means of the conduits h
which are opposite to the orifice H. The preliminary explosion which takes
place inside the valve S assists in closing it; in order to avoid the expansion and
compression of gas in the movements of this valve, the external air may be drawn
in and forced back through the orifice L at will, and circulated in its interior,
thus assisting in cooling it.
Grooves formed on the friction surfaces ensure the junctions of the pellets
and P¹ with the cylindrical surfaces A and B and "wings" formed on the outside
The
of these same cylinders, effect cooling without any circulation of water.
vehicle is set going by means of a crank mounted directly on the shaft O on
the same side as the fly-wheel V.
The explosive fluid is formed of a mixture in suitable proportions of air with
illuminating, acetylene gas, vapours of petroleum, alcohol, and ether, etc.
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
"

crowns c and C rotating in the closed circular space A B F f substantially as

page_text: metrical and opposite to one another, of the closing contrivances d and d, the
valves S and S₁ and the igniters I and I' in such a manner as to produce in turn
four explosions two together simultaneously, constituting two perfectly equili
