Improvements in connection with Engines for Driving Roundabouts.
1, FREDERICK JOHN BURRELL, of Saint Nicholas Works, Thetford, in the
County of Norfolk, Engineer, do hereby declare the nature of this invention to be
as follows:
The object of the invention is to provide a means whereby road locomotives as at
present constructed and having a dynamo carried on the front part driven by a
belt from the fly-wheel, may, without altering the design of the engine, be fitted
with a turret so as to be available for driving roundabouts by occupying the centre.
position in place of the usual centre engine.
In order to do this, I arrange a separate small engine combined with and forming
part of the turret so that turret and engine can be easily adapted to existing road
engines, steam being supplied by the boiler of the traction engine.
The engine which drives the turret may be placed in a convenient position
horizontally above the working parts of the traction engine and in such a manner
as to be easily accessible and under the control of the driver, so that one man only
is necessary to drive both engines and one boilor only is used to supply steam for
both engines.
The turret being fixed on the traction engine at the proper working height, the
roundabouts can be more quickly got to work than at present, the usual centre
engine supported on trestles and packed up to the necessary height, being dispensed
with. When not required in the centre of the roundabouts, the traction engine in
available for dragging the machine from place to place.
By placing the traction engine in the centre much valuable ground space is saved
and there is one load less to be drawn about.
The power required for lighting up the machine being about six times that
required for driving the same, the advantage of having a small separate engine to
drive the turret is obvious, thus allowing the whole power of the traction engine to
be devoted to driving the dynamo at a constant speed.

[, FREDERICK JOHN BURRELL, of St. Nicholas Works, Thetford in the
County of Norfolk, Engineer, 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 :-
The object of the invention is to provide a means whereby road locomotives as
at present constructed and having a dynamo carried on the front part driven by a
belt from the fly wheel, may, without altering the design of the engine, be fitted
with a turret so as to be available for driving roundabouts by occupying the centre
position in place of the usual centre engine.

In order to do this arrange a separate small engine combined with and forming
part of the turret so that turret and engine can be easily adapted to existing road
engines, steam being supplied by the boiler of the traction engine. The engiue

page_text: which drives the turret may be placed in a convenient position horizontally above
the working parts of the traction engine and in such a manner as to be easily
accessible and under the control of the driver, so that one man only is necessary
to drive both engines, and one boiler only is used to supply steam for both
engines.
The turret being fixed on the traction engine at the proper working height the
roundabouts can be. more quickly got to work than at present, the usual centre
engine supported on trestles and packed up to the necessary height, being dispensed
with. When not required in the centre of the roundabouts the traction engine is
available for dragging the machine from place to place.
By placing the traction engine in the centre much valuable ground space is saved
and there is one load less to draw about.
The power required for lighting up the machine being about six times that
required for driving the same the advantage of having a small separate engine to
drive the turret is obvious, thus allowing the whole power of the traction engine to
be devoted to driving the dynamo at a constant speed.
And in order that iny invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being bad to letters and
figures marked thereon.
Fig. 1, is a side elevation showing my invention applied to a road locomotive.
Fig. 2, is an end elevation of same.
In Fig. 1, a is the small engine combined with and forming part of the turret b
which carries the ring e, power being transmitted from the crank shaft d through
the gearing to the arms e eby which the roundabout is propelled. Steam is supplied
by the boiler f of the traction engine through the steam pipe f and controlled by
the stop valve g. The turret b is pinned to the top of the traction engine in about
the centre of its entire length, the smoke being carried by the beat chimney h
into the centre of the turret, the turret wheel'e being carried at the proper working
height, the usual centre engine is dispensed with.
The dynamo is driven by a belt from the fly-wheel of the road locomotive
which runs at á constant speed.
I am aware that turrets have been carried upon traction engines, but differing
from my invention in that the power of the traction engine was used for driving
the roundabout and therefore I do not claim the use of a turret combined with.or
attached to a traction engine.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In road locomotives or engines constructed to occupy the centre position of a
roundabout, and carrying a turret upon it, the use of a separate engine combined,
with or coupled to the turret for driving the roundabout, so that the main engine
may be free to drive a dynamo at a constant speed quite independently of the
turret engine, substantially as herein described and according to the accompanying
drawings.
2. In engines for driving roundabouts, the combination of turret driven by
separate engine attached to a traction engine, having a dynamo carried upon the
engine and driven from the crank shaft of the traction engine, substantially as
herein described.
3. In engines for driving roundabouts, the arrangement and combination
substantially as described with reference to Figs. 1, and 2, and for the purpose
herein set forth.
