PROVISIONAL SPECIFICATION.
Improvements in Dumb Jockeys.
I JAMES GLOSSOP of 2 Queen's Square Leeds in the County of York,
Saddler and Harness Manufacturer do hereby declare the nature of this invention
to be as follows :-
My invention refers to that class of apparatus used when breaking in or
forming the mouth of young horses, which is fitted to the back of the horse, and
to which the reins are connected in such a manner as to put a pull or tension
on the reins in imitation of a rider, and which are hence termed dumb jockeys.
An improved dumb jockey in accordance with my invention is constructed as
follows:-
Two pieces of wood suitably shaped (preferably slightly S shaped) are hinged
together about a common axis. The two lower portions fit over the back of the
horse and are connected at their lower ends with the horse girth. They are also
provided at suitable positions with pads, by means of which they rest upon the
back of the horse.
The upper portions are each formed in two parts, which are hinged together in
such a manner, that when placed on the back of the horse, the top pieces, (which
for the sake of distinction I shall call the "hand" pieces) can be bent forwards and
downwards towards the horses head. In order however to retain the hand pieces
normally in position, they are connected together by means of two straps, and a
thick rubber ring, (or other flexible spring). By buckling up or letting out one of
the straps the tension of the rubber ring (or spring) can be increased or lessened,
and so vary the force necessary to bend down and forward the "hand" pieces.
The upper ends of the hand pieces are connected to the mouth bit by means of
reins, the length of which are so adjusted that when the horse holds his head in a
normal position and the "hand" pieces of the dumb jockey are vertical, the
reins are just slack, but if the horse moves his head to one side or other
the opposite "hand" piece is drawn forwards, stretching the rubber band
(or spring) putting a corresponding tension on the rein, whilst if the horse
throws his mouth forward both the "hand" pieces are similarly put forward and a
corresponding tension is put on both reins.
By adjusting the rubber band straps, or by altring the size of the rubber band, the
tension on the rein can be adjusted equivalent to the pull of a man, a lady, or a child.
By attaching rings to the upper part of the rubber bands or top straps of the
same and connecting these with the tail band an additional check is thrown on the
horse, when making any attempt at bucking or kicking.
The hinging of the two main S shaped pieces of the dumb jockey is preferably
so arranged that they can be moved about the hinge pin only sufficiently to allow
of adjustment to suit or fit the backs of various sized horses.

Improvements in Dumb Jockeys.
I JAMES GLOSSOP of 2 Queen's Square Leeds in the County of York
Saddler and Harness Manufacturer do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention refers to that class of apparatus used in breaking in or forming

page_text: the mouth of young horses, which is fitted to the back of the horse, and to
which the reins are connected in such a manner as to put a pull or tension on
the reins in imitation of a rider, and which are hence termed dumb jockeys.
An improved dumb jockey in accordance with my invention is constructed as
follows:-
Two pieces of wood suitably shaped (preferably slightly S shaped) are hinged
together about a common axis. The two lower portions fit over the back of the horse
and are connected at their lower ends with the horse girth. They are also provided at
suitable positions with pads, by means of which they rest upon the back of the
horse.
The upper portions are each formed in two parts, which are hinged together
in such a manner that when placed on the back of the horse, the top pieces
(which for the sake of distinction I shall call the hand pieces) can be bent
forwards and downwards towards the horses head. In order however to retain
the hand pieces normally in position, they are connected together by means of
two straps and a thick rubber ring, (or other flexible spring). By buckling up
or letting out one of the straps the tension of the rubber ring (or spring) can
be increased or lessened, and so vary the force necessary to bend down and forward
the "hand" pieces. The upper ends of the hand pieces are connected to the mouth
bit by means of reins, the lengths of which are so adjusted that when the horse:
holds his head in a normal position and the "hand" pieces of the dumb jockey are
vertical the reins are just slack, but if the horse moves his head to one side or the
other, the opposite "hand" piece is drawn forwards, stretching the rubber band
(or spring), and putting a corresponding tension on the reins; whilst if the horse
throws his mouth forward both the "hand" pieces are similarly pulled forward and
a corresponding tension is put on both reins.
By adjusting the rubber band straps, or by altering the size of the rubber band,
the tension on the rein can be adjusted equivalent to the pull of a man, a lady, or a
child.
By attaching rings to the middle or upper parts of the bands, or the top straps
of the same, and connecting these with the tail band an additional check is thrown
on the horse when making any attempt at bucking or kicking.
The hinging of the two main S shaped pieces of the dumb jockey is preferably
so arranged, that they can be moved about the hinge pin only sufficiently to allow
of adjustment to suit or fit the backs of various sized horses.
And in order that my invention and the manner in which the same is to be
performed may be more clearly understood I have annexed hereto the accompanying
sheet of drawings, in which Fig. 1 is a perspective view of a dumb jockey con-
structed in accordance with my invention, as seen from the back; whilst Fig. 2 is
a part side view.
"A A', A A' are the two pieces of wood or arms hinged together at b. The
lower portions A' A' fit over the back of and are connected at their lower ends to
the horse girth. d represents the padding. The upper portions are formed in two
parts A. a, hinged together by the hinge e, the parts A A being formed each in one
piece with one of the parts A' A' respectively. a are the hand pieces, and these
are connected to the mouth bit by means of the reins ff. When the horse throws
his head to one side, the opposite side rein pulls the hand piece forwards and
downwards about the hinge e as indicated by the dotted lines in Fig. 2. These hand
pieces are normally retained in the position shewn in Fig. 1 by means of the two
straps g and hand the thick rubber ring i. By taking up or letting out the strap g,
the tension of the rubber ring can be adjusted.
kkare rings attached to the rubber bands ii, (or they may be attached to the
top straps g), and also to the tail band by means of the straps mm; so that when
the horse attempts to lower his head before bucking and kicking, the hand pieces a a
are drawn forward, and by means of the straps mm pull the tail band I and thus
check any attempt at bucking or kicking.
In addition to the dumb jockey reins ff, a second pair of reins (not shewn in the

page_text: drawings) are attached to the bit, and passed through the rings c or c¹, to enable
the driver to guide the horse.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is :-
1st. A dumb jockey consisting of two arms (such as A A¹) hinged together
capable of being adjusted to fit the back of a horse and provided at their upper
ends with hinged pieces such as a a and rubber (or other springs) such as i i
substantially as and for the purposes herein set forth.
2nd. A dumb jockey consisting of two arms hinged together capable of being
adjusted to fit the back of a horse, the lower ends being attached to the girth; and
the upper ends, provided with hinged pieces connected at the front to the reins and
at the back to rubber or other springs and to the tail band, substantially as and for
the purposes herein set forth.
3rd. A dumb jockey constructed substantially as herein set forth and illustrated
in the accompanying drawings.
