Improvements in or relating to Roundabouts.
I, ARTHUR JENKINSON, of 89 Duke Street, Sheffield, in the County of York,
Edge Tool Maker do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in Roundabouts such as are generally
used for pleasure in markets or fairs its object being the construction of an
arrangement whereby horses revolving by any suitable mechanical means are
made to jump hurdles, fences, or like obstructions, at intervals as well as retaining
the ordinary galloping or oscillating motion.
According to this invention I arrange at any suitable height above the horse
any suitable rail rails or road, preferably in a circular shape and on the rail, rails or
road I arrange suitable projections which are meant to give an oscillating motion
to the horse by means of two connecting rods preferably at the sides of the horses.
The ends of the rods are carried on the rail, rails, or road by independent bars
axles, or carriers the ends of which can be carried if necessary on wheels and alsq
fixed in suitable guides which can also be fixed in the revolving frame above the
rail, rails or road and bearing on wheels if necessary at any suitable angle so that
in revolving the machine or frame the bars axles or carriers meet with the
projections of the rail, rails, or roads and ride over them; thus when one carrier
is riding over the aforesaid projection the other is receding or running parallel on
the rail rails or road thus obtaining the up and down oscillating motion of the
horse by the connecting rods attached to the bars axles or carriers and attached to
a frame fore and aft by the side of the horse.
Thus we obtain the aforesaid galloping motion.
Again at any suitable position on the rail rails or roads at intervals I form
another or other larger projection of any desired shape so as to cause the horses
to have a jumping motion over the hurdle fence or like obstruction by the bars
carriers or axles taking the suitable larger projections on the rail, rails or roads.
After the horse has taken this jumping attitude by the large projection it comes
on the parallel rail rails or road until the bars axles or carriers meets with the
smaller curvature projection giving the horse a galloping motion.
Underneath the rail rails or road I suspend a sliding bracket of any desired
shape which encloses the connecting rods to the horse. And at the bottom of this
said bracket I arrange a movable plate which acts as a stay to the horse in its
revolutions and I make any suitable arrangements such as a stop catching this
movable plate. so as to regulate the oscillation of the up and down motion of the
horse and to prevent accidents.
Again if necessary I can extend one or both or more bars axles and carriers
so as to meet any suitable projection outside of the guides so as to give the horse
either a bucking rearing or any desired attitude independent of the galloping and
jumping arrangement.

page_text: I do not bind myself to the number of horses I may apply either abreast or
otherwise nor to the angle of the guides or to the shape or curvatures of small
or larger projections on the rail rails or road and any suitable mechanical power
may be used for propelling the frame and the guides, which may be bracketted
or fixed to the revolving frame carrying the bars axles or carriers around the
fixed rail rails or roads and over the suitable projections thereon. The revolving
frame may be fixed or carried by any suitable means.

Improvements in or relating to Roundabouts.
i
I, ARTHUR JENKINSON, of 89 Duke Street, Sheffield, in the County of York,
Edge Tool Maker, 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 improvements in roundabouts such as are generally
used for pleasure in markets or fairs its object being the construction of an
arrangement whereby horses revolving by any suitable mechanical means are
made to jump hurdles fences or like obstructions at intervals as well as to retain
the ordinary galloping motion.
In the accompanying drawings,
Fig. 1 is an elevation partly in section of a roundabout, comprising improve-
ments according to this invention.
Fig. 2 is a half plan of the same.
Like letters indicate like parts throughout the drawings.
In constructing my roundabout I form'a floor A and upon the same fix or fasten
some kind of obstruction or hurdle B; overhead I form a flooring or platform CC
of iron or other suitable material supported by pillars and upon this plat-
form C C I place rails or tracks D D₁ having a number of curves or humps such
as D2 D3 and D.
I preferably place at the centre of the roundabout a framing E having a number
of projections E (Fig. 1) forming guides the frame E being fastened to the
central socket E2 by suitable arms E³, (being made in segments) if desired.
The frame E is caused to revolve.
Underneath and.at a.suitable distance from the platform c¹ I suspend a circular
plate or plates F from the frame E by distance pieces and bolts F which hold
the plate F in suspension.
Upon the plate F I place a number of slides G each preferably carrying a
frame G¹ at its base containing a movable plate G2 which can be tilted and fixed
as desired.
Within the guides of the projection E of the frame E are carried spindles H H¹
with rollers H2 H3 which run on the rails D Dr.
From the spindles H H₁ are suspended one or more rods H4 H5 attached at
their lower ends. H6 H7 to the fore and hind parts of the horses K; the
spindles H H. are: preferably strapped together by leather or other suitable
strappings to prevent them when taking the downward part of the curves D2 D3 D4
from descending too fast.

page_text: From the socket E of the frame E, tie rods E extend to the circumference of
the latter. In the plate F and also in the guides G I cut or form clearance holes
as F2 and G³ for the connecting rods H H. It will be readily understood that as
the spindles H H¹ are carried around by the projections E¹ of the frame E they
cause the rollers H2 H3 to surmount the various curves or humps D2 D3 and D
so making the horses K to rise and fall so that they have a jumping galloping
or similar motion.
.
The connecting rods H+ H³-are-drawn-nearer to one another when the rollers H³
and H³ take the curves or humps. Thus for instance in jumping the hurdles or
obstructions B the slide G is slightly retarded in its revolving motion by the
checking of the rods H³ as the runners mount the curves so that the horse simulates
the natural action.
The movable plate G2 regulates the angle or position of the horses K when taking
their motion from the spindles H and H' in either ascending or descending the
curves D2 D3 and D.
When the rollers are ascending say the greatest curves such as D² the horses
are put at an angle by that position and the rods H H become nearer together
providing the movable plate G2 is in a vertical or as near as possible a vertical
position, so as not to affect them; but as soon as the movable plate G2 is fixed in
a more horizontal position it has a tendency to keep the rods H H apart from
one another whatever the curvature may be on the rails and it therefore compels
the horses K to rise either in a parallel or angular position according to the
relation of the plate G2 to the rods H H thus the horses can surmount the
obstacles in a parallel or any desired angular position, even if the spindles H
and H are taking the greatest curves.
It must be understood that other suitable devices such as boats, hounds, stags
or such like objects may be used and given the desired motion by the above
described arrangement.
In the preceding description the rollers or wheels H2 H3 are described as being
within the frame E, so that every row of horses meet, the same humps or curves of
the rails, but if necessary I can arrange on the platform ce¹ (outside or inside of
the frame E) other rails or tracks and curves for some of the horses if desired, as
for instance one row of horses might be made to continually buck jump the other
being operated in another manner on another track.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
"
1. In a roundabout the combination of a rotating frame such as E rollers such
as H2 H3 a "humped" or similar track along which the rollers are propelled by
the frame and "horses" or other passenger-carrying devices suspended from the
axles of the rollers 'for the purpose described.
2. In a roundabout of the kind described the combination with rods such as H4 H5
carried by rollers which traverse a "humped" track, of a travelling frame such as G
having an adjustable device such as G2 for the purpose described.
"
or
3. In a roundabout of the kind described the combination with "horses
other passenger carrying devices operated by rods such as H H in the manner
described of means for regulating the angle at which the "horses" surmount
obstacles substantially as described.
4. In a roundabout of the kind described the combination with a rotating frame
such as E of a plate such as F and sliding frame such as G substantially as and
for the purpose described.
5. In a roundabout imparting a jumping galloping or similar motion to a horse
or other passenger carrying device by apparatus arranged and operating sub-
stantially as and for the purpose described.
6. The combination and arrangement of parts constituting the complete round-

page_text: about substantially as and for the purpose described and illustrated in the
accompanying drawings.
