page_text: WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN THE MEANS EMPLOYED FOR TRANSMITTING AND ARRESTING MOTION ON RAILWAYS
FROM THE LOCOMOTIVE TO THE CARRIAGES AND TRUCKS," and have petitioned
Her Majesty to grant unto me, my executors, administrators, and
assigns, Her Royal Letters Patent for the same, and have made solemn
Declaration that it has been communicated to me from abroad by
Orange McConnell Chamberlain, of 13, Rue Gaillon, Paris, Engineer.
NOW KNOW YE, that I, the said William Morgan-Brown, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be peformed, in and by the following
statement thereof, that is to say :-
This Invention of improvements in the means employed for trans-
mitting motion on railways, from the locomotive to the rolling stock,
consists in augmenting the adhesion of the trains to the rails without
increasing the power of the locomotive by applying the force of the
locomotive to all the wheels of the train, which being connected together
become thus all driving wheels. To obtain this result I employ pulleys
and endless chains or bands to unite the axles of the same wagon
together, and gearing to unite the locomotive to the wagons, as well as
cach wagon to the other.
In the two Figures of the Drawing hereto attached forming part
of this Specification I have represented the new system adapted to
railway wagons, Figure 1 being a plan, and Figure 2 a longitudinal
elevation.
In these Figures a, a, represent the rails; b, b, the wheels; c, c, their
axles; and d, d, the framing of the wagons, according to the system in
actual use; e, e, are two pulleys keyed upon the axles c, c; and f, an
endless chain clipping these pulleys, so that the movements of the axles
shall be simultaneous, whatever the direction in which the train moves;
g, h, and i are the gears serving to unite the locomotive to a wagon, or
two wagons to each other. The wheels g and h, which are of the same
diameter, are keyed upon the axles c, c; the wheel i, which is of a lesser
diameter, is an intermediate one gearing into the two wheels g, h, of
which it serves to transmit the movement either from g into h or from
h into g.
So as to be able to regulate the degree of penetration or
gearing of the teeth of i into g, h, as well as to prevent their being broken
accidentally when the wagons are coupled, it is essential that this intor-

page_text: mediate may be easily moved out of gear when desired at any time.
Different dispositions may be adopted for this purpose. It will suffice
that I indicate it, which consists in mounting this intermediate wheel in
the extremity of a frame k suspended by its centre on the axle o, and of
which the other extremity is connected by a link to a screw shaft m,
which is lifted and lowered by the wheel nut n turning in the support o.
The frame k, shown to the right of Figures 1 and 2, is represented with
its intermediate wheel geared into the driving wheels g and ⁄;`that
of the left is represented with the lever in the position that it only
gears with the wheel g, the wheel of the wagon following being out of
gear:
"
The advantages resulting from these improvements are as follows:-
A more effective traction in consequence of the great increase in the
adhesion, a more effective power to stop the train, because when the
locomotive stops each wheel being stationary opposes its movement, a
single brake on the locomotive or on one of the wagons reacts on all the
train; in the same way by the reversing of the motion of the locomotive
each wheel of the train bears its contingent of resistance to that of the
locomotive, economy in the weight and consequently in the price of the
locomotive, since it is the entire weight of the train which produces the
adhesion of the wheels, and not the locomotive alone; a locomotive
with one pair of wheels suffices for all the train of whatever nature it
may be economy in the construction of the permanent way caused by
the diminution of the weight of the locomotive.
Having now described and particularly set forth the nature of the
said Invention, and the manner of carrying the same into effect, I would
have it understood that what I claim is, the means herein indicated of
coupling the wheels of locomotives and railway carriages for the pur-
poses set forth, substantially as described.

hereunto set my hand and seal, this Tenth day of September, in
the year of our Lord One thousand eight hundred and seventy-
