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:-
My invention relates to the class of roundabouts wherein models of horses or the
like are given movements resembling the movements of horses my said invention
having for its object to provide simple and efficient mechanism for the said
roundabouts.
The model horses may be suspended in the usual manner by rods from cranked
spindles carried by the revolving top and receiving motion from bevil gearing
round the central support by coupling rods with universal joints. Beneath the
models of horses is a continuous circular platform or analogous support suspended
from the radial arms or levers of the revolving top framework.
The "horse irons" viz. the rods by which the models of horses are suspended or rods
depending from the undersides thereof are made sufficiently long to pass downwards
through guides or orifices in the platform or analogous support preferably through
swivelling guides which are carried (at distances apart corresponding with the
distances apart of the cranks) in a frame free to slide in grooves or guideways fixed
to the platform or support in a radial direction from the centre of the machine
leaving the models of horses free to swing out as the roundabout revolves.
As the roundabout revolves and the top cranked spindle is caused to rotate on
its axis the models of horses have a rising and falling motion given to them and
they are kept the proper distance apart by the lower ends of the horse irons
passing through the aforesaid guides or orifices whilst when these guides or orifices
are arranged to slide radially as described the models of horses can swing freely
away from the centre into the position which they naturally assume owing to the
centrifugal force.

COMPLETE SPECIFICATION (AMENDED).
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 and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
My invention relates to the class of roundabouts wherein models of horses or the

page_text: like are given movements resembling the movements of living horses or the like
my said invention having for its object to provide means whereby the model horses
or the like are maintained at the proper distances apart circumferentially or one in
advance of another and further so that they are if-desired free to move either
separately or collectively radially away from and towards the axis of the
roundabout. I will refer to these models as "horses."
The horses may be suspended and have motion given to them in any convenient
or usual way such as for instance by rods from cranks on shafts supported by
radial arms carried by the revolving top the said shafts being rotated by bevel
gearing arranged round the central support and connected to the said shafts by
coupling rods with universal joints as is well understood. Beneath the horses is a
circular or annular platform or analogous support suspended from the radial arms
carried by the revolving top.
The horse-irons" or rods by which the horses are suspended or rods depending
from the undersides thereof are made sufficiently long to pass downwards through
guides slots or orifices in the platform which preferably allow the horses to swing
out radially as they revolve they the said horse-irons preferably passing through
swivelling guides which are free to slide in slots or guideways provided in or fixed
to the platform or analogous support in a radial direction from the centre of the
machine, leaving the horses free to swing out as the roundabout revolves.
As the roundabout revolves and the cranked shafts are caused to rotate the
horses have a rising and falling motion given to them by the cranks and they are
kept at the proper distance apart circumferentially or one in advance of another
by the lower ends of the "horse irons passing through the aforesaid guides or
orifices whilst when radial movement is allowed for as described the horses can
swing away from the centre into the position which they naturally tend to assume
owing to centrifugal force.
Figure 1 of the drawings represents in elevation so much of a roundabout as is
sufficient to illustrate an arrangement according to my invention for keeping the
horses at the proper distance apart both radially and one in advance of another,
Figure 2 is a similar view illustrating un-arrangement necording to -my-invention
and for permitting the horses to move in a radial direction by the centrifugal force
due to the motion of the roundabout but maintaining them at suitable distances
apart one in advance of another and Figures 32, 4 3 and 5 4 illustrate a suitable
construction of sliding and swivelling guides for permitting of the said radial
motions of the horses whilst maintaining them at the proper distances apart circum-
ferentially. The horses A are suspended by rods B from cranks C, the upper ends
of the rods B being pivotted as at a to the bearing for the crank pins so as to
permit of the rocking or swinging motions of the horses when the roundabout is
in action.
I have not shewn the gearing for transmitting rotation to the crank shafts as
this may be of the usual kind.
In the arrangement illustrated in Figure 1 the The rods or projections B2
which may be either extensions of the rods B or separate rods or projections
attached to the horses. pass through-holes b-in-the platform D so as to keep the
horses ut uniform distances apart both radially-and-circumferentially and serve as
guides to steady them in their rising and falling movements. In the arrangement
illustrated by Figure 2 The horses A are permitted to move in a radial direction
whilst receiving the rising and falling and the rocking or galloping motions
imparted to them by the cranks C. The rods or projections B2 pass through guide
eyes E, provided with trunnions by which they are mounted and can swivel in
brackets F, see Figures 32, 4 3 and 4, which may be fixed on a frame G, as
shewn in Figures 32 and 5 4 to maintain the horses at a certain distance apart the
frames G being fitted to slide in guides H arranged on the platform D radially
from the centre of the apparatus so as to permit of the horses attached to the
rods B moving outwards under centrifugal force. Or if desired the frames G may
be dispensed with and suitable guides such as E be fitted to slide separately in

page_text: radial slots or guides in or attached to the platform or the irons themselves may
slide radially in such slots or guides.
The platform D is suspended by rods K from the radial arms L carrying the
bearings in which the crank shafts C' are mounted the whole being caused to
revolve round the axis I by gearing in the ordinary or any convenient manner.
As the speed of rotation increases the centrifugal force will cause the horses to
move the sliding frames G outwards more or less, and the horses to lean sideways
towards the axis I the swivelling guide eyes E through which the rods or
projections B2 pass permitting of the said rods assuming an angular position thus
giving to the horses a motion which resembles the galloping motions of a horse
when turning corners.
I do not limit myself to the precise details shewn in the drawings the essential
features of my invention being the guiding of the horses by rods depending from
their undersides and working up and down in guides in the platform and further
the provision of means for allowing of radial movement substantially as set forth.
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
-
1. A roundabout in which-models of horses or the like are onused to receive
movements resembling-the-movements of horses and are also capable-of-moving
and are guided in a radial direction relatively to the axis on which the roundabout
turns substantially as hereinbefore described.
In roundabouts in which models of horses or the like are caused to receive
movements resembling the movements of horses, depending rods or projections
extending from the model horses or the like through swivelling or equivalent
guides fitted to slide radially on a rotating platform or analogous support, so as to
permit of the model horses or the like moving either independently or collectively
in a radial direction under centrifugal action substantially as hereinbefore described.
3. A roundabout in which models of horses or the like are caused to receive
movements resembling the movements of a horse-or-the-like-the models of horses
or the like being provided with rods or projections-to-slide-up and down-in-holes
elots or guides in the rotating platform of the roundabout for the purpose of
keeping the model horses or the like at suitable distances apart substantially as
hereinbefore described-with-reference to Figure 1 of the accompanying drawings.
Dated this 21st day of September 1891.
