A Motor for Shunting Rolling Stock on Railways and other.
Purposes.
DIGBY DE LA MOTTE DU BOULAY Captain in Her Majesty's 7th Dragoon Guards
Avishayes Shaftesbury Dorset do hereby declare the nature of this invention to be as
follows:-
The revolving fly wheel such as above described is made to revolve very rapidly
by means of multiplying wheel or wheels &c. When it is going a good pace or
what is judged to be sufficent pace it is suddenly connected with an everlasting rope
or chain or strap and this power may be used to start or shunt trucks &c. or raise
weights &c. &c. &c. The revolving fly wheel &c. may be either stationary and move
what is required by a direct connection or it may be on a carriage or trolly which it
will impel forwards or backwards or sideways &c. and so drag with it what it is
required to move &c. by means of the object or objects being connected by a
rope or chain &c. to the trolly &c.
The trolly could run on a narrow guage parallel to the lines of railway on which
it was required to move trucks &c. In this case it would go where the horse does at
present. One of the objects of this invention is to substitute it as much as possible for
the horses used on railways &c. for shunting &c. This would save a good deal of
expense in horses &c.
It could be worked by one or two men.

A Motor for Shunting Rolling Stock on Railways and other
Purposes.
I DIGBY DE LA MOTTE DU BOULAY Captain in Her Majesty's 7th Dragoon Guards
of Avishayes Shaftesbury Dorset 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 relates to means by which heavy bodies may be moved or set in
movement, its purpose being principally for the shunting of railway vehicles, and
lifting of goods. The invention consists in so mounting a heavy fly-wheel or other
body that it may be brought into rotation, the momentum of the revolving fly-wheel
or body being afterwards converted into a force operating on the matter to be moved
in the direction in which it is to travel or to be lifted.
Referring to the accompanying drawings which illustrate a mode of performing my
invention.
Fig. 1 is a sectional elevation of the motor.
Fig. 2 a side elevation and Fig. 3 a plan thereof.
A is a heavy fly-wheel mounted on the shaft B journalled in bearings C. C firmly
attached to a suitable foundation D.-E is a pulley fixed on the shaft. Fa tooth pinion
revolving loosely on the shaft; G a clutch revolving with the shaft and operated so as
to engage the pinion F by suitable means such as lever J with fork H. L is a large
tooth wheel mounted on a shaft N journalled in bearings Q and R, said tooth wheel
gearing with the pinion F and operated by crank M fitted on to the square head P.
The crank M¹ being placed on the square head 0, the shaft B may be set in slow
rotation.
When sufficient speed is given to the fly-wheel A, the crank M³ may be shifted to
the head P (or a separate crank M as shown may be used) and the clutch G engaged,
by revolving the crank M on the head P the speed of the fly wheel A may be still
further increased. A rope S attached to the vehicle or matter to be moved or raised is
brought near the pulley E. The clutch G is disengaged and two or three turns of
the rope are made over the pulley E so that the whole force of the revolving fly-wheel
or body A is exerted as a direct pull on the vehicle or other object to be moved.
In largo yards a suitable number of these apparatus should be placed at convenient
stations so as to enable the rolling stock or other matter to be moved in any part of
the yard or in any direction that may be required.
When used for shunting purposes the motor herein described may also be mounted
on a truck or carriage, adapted to run on rails, this truck or carriage being attached
to the vehicles to be shunted. The fly-wheel having attained the required momentum
will then be geared by pulley E to the axles or wheels of the truck so as to propel the
latter and so shunt the vehicles. I do not confine myself to any special details in the
construction or arrangement of the parts.

page_text: 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 :-
In a motor for setting in motion and moving railway rolling stock and lifting
materials and for other purposes:—
1. The application of the momentum of a heavy revolving fly-wheel to the movement
of rolling stock and generally to the moving or lifting of bodies.
2. A Hy-wheel or heavy body A mounted on a shaft, B adapted to revolve in
combination with pulley E as and for the purpose set forth.
3. The combination of a fly-wheel or heavy body A mounted on a shaft B adapted
to revolve a pulley E on the same shaft, a clutch & thereon, a tooth wheel F revolving
loosely on said shaft and square head O, with tooth-wheel L gearing into tooth
wheel F and square head P for operating said tooth-wheel L by means of a hand crank
substantially as and for the purpose set forth.
