JOSEPH BRINDLE, of 14 and 16, Field Street, Failsworth, near Manchester,
Engineer, do hereby declare the nature of this invention to be as follows;-
This invention is for the purpose of adjusting the distance between horses on
roundabouts; to keep such horses at a fixed distance from each other so as to
prevent any possibility of a collision between one horse and another.
To effect my purpose I use the ordinary rotating platform and upon this plat-
form the horses are placed in the ordinary way. There may be two, three or
more horses abreast as required. Underneath this platform I attach or fix three
arms, two of which I attach or fix to and underneath the rotating platform. I
attach;-
1st. A small arm fastened at one end to the rotating platform.
2nd. A longer arm fastened also at one end to the rotating platform and point-
ing to the loose end of the smaller arm.
3rd. A longer arm still but this is placed upon the loose ends of the two
arms above mentioned and is coupled at one end to the small arm, and about the
centre to the larger arm. The coupling is made at the loose ends of the two arms
that are fixed to the platform.
It will be understood that where two or more dobby horses go abreast that I
use a similar arrangement for each horse and I use a connecting rod to fasten the
long arms (No. 3) together.
The rotating platform being in the ordinary position with the dobby horses
upon it, I secure the dobby horses to the long arins (No. 3) by means of the usual
rod fitted into a socket at the end of arm No. 3.
Then when the platform begins to rotate, and the horses assume a galloping
motion, this invention causes the horses to swing out all together and keeps them
at regular distances from each other.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention is for the purpose of adjusting the distances between horses on
roundabouts, to keep such horses at a fixed distance from each other so as to pre-
vent any possibility of a collision between one horse and another and also to
prevent any undue backward or forward motion. To effect my purpose I use the
ordinary rotating platform and upon this platform the horses are placed in the
ordinary way. There may be two, three or more horses abreast as required,
Underneath this platform I attach or fix three radial arms two of which I attach
or fix to and underneath the rotating platform. I attach first a small arm No. 1
on the drawing at one end to the rotating platform, Secondly a longer arm No. 2
on the drawing fastened also at one end to the rotating platform and pointing
to the loose end of the small arm No. 1. Thirdly a longer arm still No. 3 on the
drawing but this is placed upon the loose ends of the arms No. 1 and No. 2 and
is coupled at one end to the loose end of the small arm No. 1 and about the
centre to the loose end of the larger arm No. 2. It will be understood that where
two or more dobby horses go abreast that I use a similar arrangement for each
horse and I use a connecting rod No. 4 on the drawing to fasten the largest
arms No. 3 together. The rotating platform being in the ordinary position with
the dobby horses upon it, I secure the dobby horses to the longest arms No. 3
by means of the usual rod 5 fitted into a socket 5 at the end of the longest
arms No. 3. Then when the platform 6 begins to rotate and the horses assume a
galloping motion this invention owing to the centrifugal force, which causes the
horses to swing out controls the horses and keeps them at regular distances from
each other and also prevents any undue backward or forward motion.
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:-
The invention of the radial arms Nos. 1, 2 and 3 on the drawing and the con-
necting rod No. 4 on the drawing and which control the distances of the horses
one from another and also prevent any undue backward or forward motion of the
horses during the action of the centrifugal forcé.
