page_text: We THOMAS BLINKHORN and WILLIAM SIMPSON KEY both of 18° Norfolk
Street Boston in the County of Lincoln Engineers do hereby declare the nature
of this invention to be as follows:-
Our invention relates to improved means for imparting a galloping movement
to horses or other animals mounted upon a roundabout of the kind described in
the Specification of a former Patent granted to us No. 3200 in 1885.
The roundabout as described in the Specification of this former Patent is con-
structed of a number of wooden frames connected together end to end to form a
horizontal ring which is made to rotate in any suitable manner.
Underneath each frame is an angle iron frame which is supported by a pair of
wheels and is jointed at its forward end to the upper frame and at its rear end
pressed downwards by springs interposed between the two frames.
Each lower frame carries a horse or other animal in the following manner.
Attached to and between the upper part of the fore legs of the animal is a cross
bar from which rods descend to a block or bearing which is carried by the pin of
a crank on the axle of the pair of wheels by which the lower frame is supported.
From under the centre or somewhat in rear of the centre of the body two
upright wooden springs pass downwards to the under frame.
When the fore part of the body is raised by the crank the springs are unbent
but become bent when the fore part of the body is drawn downwards by the crank.
When the crank commences to again lift the fore part of the body the springs
assist it to do so.
In this way the tendency of the weight of the rider to cause the wheels to run
faster when the fore part of the body is descending than when it is ascending is
counteracted and a more uniform movement is obtained.
In place of the cross bar attached to the front legs and the rods descending from
it to the crank, the front legs may be left free and the hoofs of the hind legs have
a rod passed from them to a crank on an axle which is driven by toothed wheel
gear from the axle of the pair of wheels by which the frame is supported and
which act as driving wheels.

We, THOMAS BLINKHORN and WILLIAM SIMPSON KEY both of 18 Norfolk
Street Boston in the County of Lincoln, Engineers 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 :-
Our invention relates to improved means for imparting a galloping movement
to horses or other animals mounted upon a roundabout of the kind described in the
specification of a former Patent granted to us No. 3200 in 1885.
The roundabout as described in the specification of this former Patent is con-
structed of a number of wooden frames connected together end to end to form a
horizontal ring which is made to rotate in any suitable manner.
Underneath each frame is an angle iron frame which is supported by a pair of
wheels and is jointed at its forward end to the upper frame and at its rear end
pressed downwards by springs interposed between the two frames.
Each lower frame carries a horse or other animal in the following manner :-
Attached to and between the upper part of the fore legs of the animal is a cross
bar from which rods descend to a block or bearing which is carried by the pin of
a crank on the axle of the pair of wheels by which the lower frame is supported.
From under the centre or somewhat in rear of the centre of the body two
upright wooden springs pass downwards to the under frame.
When the fore part, of the body is raised by the crank the springs are unbent
but become bent when the fore part of the body is drawn downwards by the crank.
When the crank commences to again lift the fore part of the body the springs
assist it to do so.
In this way the tendency of the weight of the rider to cause the wheels to run
faster when the fore part of the body is descending than when it is ascending is
counteracted and a more uniform movement is obtained.
In order that our said invention may be most fully understood and readily carried
into effect we will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation of a horse mounted in accordance with our
invention.
A is the under frame jointed at A¹ to the upper frame to which it is also con-
nected at its rear by the springs A2 B are the rods supporting the fore legs of the
horse They descend to the block or bearing B¹ on the pin of the crank C.
the springs which support the centre of the body of the horse.
E are
In place of connecting the two frames together by means of springs at the rear
of the horse as shown in Figure 1, they may be connected by means of hanging
rods, as shown in Figures 2 and 3. In these figures F. G are brackets fixed
respectively to the upper and lower frames. These brackets are connected together
by the hanging rods H H.

page_text: In place of the cross bar attached to the front legs and the rods descending from
it to the crank, the front legs may be left free and the hoofs of the hind legs have
a rod passed from them to a crank on an axle which is driven by toothed wheel
gear from the axle of the pair of wheels by which the frame is supported and
which act as driving wheels.
Figure 4 shows a side elevation of a horse mounted in this way.
Figure 5 is an end view of the supporting wheels and gear-In this case also as
is shown, the centre of the body of the horse is supported on springs.
.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The use of springs for supporting horses and other animals on roundabouts
substantially as described.
2. The method of supporting and giving motion to horses and other animals
on roundabouts substantially as described and shown in Figure 1 and also the
modification shown in Figures 2 and 3.
3. The method of mounting and supporting horses and other animals substan-
tially as described and illustrated in Figures 4 and 5.
