Improvements in Roundabouts.
I, FREDERICK SAVAGE of St. Nicholas Iron Works, Kings Lynn in the County of
Norfolk Engineer do hereby declare the nature of this invention to be as
follows:-
This Invention has for its object improvements in roundabouts.
The improvements have reference to roundabouts in which horses or other animals
or seats for riders are suspended from cranks on crank shafts which are carried radially
in bearings on a circular horizontal frame capable of being revolved around a central
vertical axis and in which each radial crank shaft has three or other number of cranks
upon it and a separate horse suspended from each crank-and in which also
the horses are free to swing outwards away from the central vertical axis as they
travel around it as described in the Specification of a Patent No. 15383 in the
year 1885.
The three or other number of horses in each set I suspend by separate rods from
cranks on one radial crank shaft. At the upper end of each rod I provide a joint
which allows of the lower end of the rod moving outwards away from the central axis
as the roundabout revolves, and in order to ensure that the three or other number of
horses in each set shall remain at the same distance apart as they are carried around
the central vertical axis I make the rods of each set to descend through links or loops
forming part of a horizontal frame and this frame I suspend in such a manner as to
leave it free to swing towards or away from the central vertical axis. In this way if
one horse swings outwards or inwards the other horses in the same set are carried
along with it.
The rods hanging down from the several crank shafts are braced together in pairs
to ensure uniformity of motion.

invention, and
Figure 2 is a back elevation of the same.
a a is the horizontal framework suspended from a central vertical axis in the usual
way is one of the radial crank shafts it is carried in bearings on the bars a, a, a as
shewn in figure 2-c, c, e are suspension rods working upon the cranks, they are
pivoted by means of pins d to bearings e upon the cranks, so that they
not only move up and down but are also free to swing outwards as the roundabout
revolves The suspension rods c pass through links or loops (shown in plan at
figure 3) which are carried by a frame suspended by the bars hinged to the frame a

page_text: as shown in figure 2 and are provided with steel ferrules to protect them at the place
where they pass through the loops -The suspension rods c which carry two
adjacent sets of horses are braced together in pairs by means of the rods ; as shown in
figure 1.
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. Suspending the horses, animals or seats of each set by separate rods from cranks
on a single radial crank shaft substantially as described.
2. Keeping the distance between the horses animals or seats of each set, constant,
by links or loops surrounding the suspension rods substantially as described.
3. The method of bracing together two sets of horses animals or seats substantially
as described.
4. My improvements in roundabouts substantially as described.
