A New or Improved Instrument or Appliance for the Cure of Sand
Cracks in the Hoofs of Horses and other Animals.
I, JOHN ARNOLD of the firm of Arnold and Sons, of West Smithfield in the City
of London, Surgical Instrument Makers do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to provide a simple and efficient instrument or
appliance for the cure of sand cracks in the hoofs of horses and other animals.
According to my invention I arrange on a spindle which is screw threaded at one
end with a right hand thread and at the other end with a left hand thread a clip or
clamp free to travel on the thread. There is a nut between the two, which can be
operated by a spanner. The clips or clamps are placed on the hoof one on each side
of the sand crack, the hoof being prepared to receive the instrument by filing a groove
thereon for same and notches for the clips or clamps, the clamps clip in the notches
and by turning the nut on the screw the two clips or clamps come towards each other
and so draw the horn of the hoof together and the crack is thus prevented from
extending.

Cracks in the Hoofs of Horses and other Animals.
I, JOHN ARNOLD, of the firm of Arnold and Sons, of West Smithfield, in the City
of London, Surgical Instrument Makers 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:-
The object of my invention is to provide a simple and efficient instrument or
appliance for the cure of sand cracks in the hoofs of horses and other animals.
According to my invention I arrange on a spindle which is screw threaded at one
end with a right hand thread, and at the other end, with a left hand thread, two clips
or clamps which may be caused to travel on the respective threads. There is a nut
on the spindle between the two clips, which can be operated by a spanner.
In order that my invention may be more fully understood and readily carried
into effect I will proceed to describe the same by reference to the accompanying
drawings.
Figure 1 is a plan view of an instrument or appliance for the cure of sand cracks in
the hoofs of horses and other animals, constructed according to my invention shewing
the same applied. For the sake of clearness the instrument is drawn twice the
ordinary size; Figure 2 is a perspective view of one of the grippers detached ;
Figure 3 is a perspective view of the instrument shewn applied, and Figure 4 shews
the accompanying spanner for adjusting the width apart of the grippers.
Similar letters of reference refer to like parts in all the figures.
A A¹ are the clips, clamps, or grippers made as shewn with hooks or holders for
taking into the hoof of the animal. B is the spindle having a right hand thread at
one end and a left hand thread at the other, and on which screw spindle the clips,
clamps or grippers are caused to travel when the screw spindle is revolved. C is a
nut made in a piece with, or fixed to, the screw threaded spindle B.
To use the instrument, notches are cut in the hoof one on each side of the crack
to be cured, and into each notch, the hook or bolder part of the clips, clamps or
gripper A A¹ are inserted, then by turning the nut C by a spanner such as is shewn
at Figure 4 the said clips, clamps or grippers A A¹ are brought towards one
another owing to the threads on the spindle B being cut in opposite directions and
they are there held and maintained so long as may be necessary, and in such manner
that the horn of the hoof is drawn together and the crack thereby prevented from
extending, and heals.
When the instrument is in position the tension can be regulated with the greatest
nicety and according to circumstances.
By turning the nut C with the spanner in the contrary direction to that for tightening
up, the clips, clamps or grippers are gently and gradually released and the instrument
thereby removed or falls off.

for same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The new or improved instrument or appliance for the cure of sand cracks in the
hoof's of horses or other animals composed of clips clamps or grippers A A¹, on
right and left hand screw threaded spindle B, with central nut C, arranged, constructed
and acting substantially as hereinbefore described and illustrated with reference to
the accompanying drawings together with any mere modification or modifications
thereof.
