ROBERT CANNING JONES of 196 Blackfriars Rd in the County of Surrey
Wholesale Ironmonger, Trading as Jelley Son & Jones and JOHN WILLIAM
CUNNINGHAM manager to the above, do hereby declare the nature of our invention
for SLIPPING APPARATUS FOR INSTANTLY RELEASING OR DETACHING FALLEN
HORSES & OTHER ANIMALS FROM VEHICLES be as follows:-
Our Invention relates to an Improvement in Slip Links whereby pole chains or
other parts of Harness may be instantly released or detached in the event of
Horses falling down.
Our Slipping Arrangements consists of a Hook with a Lever which is hinged or
pivotted at the extreme end & to the other end of the Falling Lever is provided a
Nib or Projection which is formed in such a way that the Lever when closed forms
the neck of the Hook perfectly round.
The Neck is provided with a revolving Slotted Collar which is actuated on by
means of a Pin fastened in the round Neck by which means the Hook is fastened
or unfastened.
The top part of the Hook above the Revolving Collar is provided with a Shackle
for connecting it to the Harness or Vehicle.
The falling Lever is held in a locked position by means of the Revolving Collar.
The operation is as follows
Supposing the Hook to be attached to the Harness by the Shackle at one end, &
the Link of the Pole Chain inserted into the hinged Hook when closed, any pressure
will be brought to bear on the point where the Falling Lever is hinged or pivotted
to the Hook.
To release the Chain, you simply turn the revolving Collar into such a position,
that the Slot comes opposite the corresponding portion of the Falling Lever, thereby
allowing it to escape or fall out instantly.

Road in the County of Surrey Wholesale Ironmongers and JOHN WILLIAM
CUNNINGHAM Manager to the above, do hereby declare tho nature of our said
invention for "SLIPPING APPARATUS FOR INSTANTLY RELEASING OR DETACHING
FALLEN HORSES AND OTHER ANIMALS FROM VEHICLES" 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 improvements in slip links whereby the harness of
horses may be instantly released or detached from pole chains or other parts of
vehicles in the event of the horses falling.
Our improved slip link which is illustrated by figures 1 and 2 on the
accompanying drawing consists of two curved or hooked parts a and b the part a
being formed at one end with a cylindrical head or shank c and at its other or
outer end with a jaw d to which is hinged one end of the other curved part b
which overlaps the part a and constitutes a lever having its fulcrum at d that is to
say the direction of any pulling strain on the overlapping curvature of the part b
of the link will be outside the fulcrum d.
The other end of the curved or lever part 6 has a square shaped lip or lug e
which when the two parts a and b are closed together so as to form the link as
seen in figure 1 takes into a recess f (figure 2) in the head or shank c.-g is a bush
or collar surrounding the head or shank c and normally pressed downwards by a
spiral (or other) spring / placed between it and a gland i which is retained in
position by the shackle; on the outer end of the head or shank c-the shackle j
connecting the link to the harness of the horse.
Though and along the circumference of the bush or collar g is a slot k termi-
nating at each end in a receding notch for receiving the stud or pin which
projects from the head or shauk c-A square shaped gap m is also formed through
the circumference of the bush or collar g for the passage of the lip or lug e on the
end of the lever part 6 of the link.
b
The action of our improved slip link or apparatus is as follows:-
Assuming the link to be closed and its various parts in the position seen in
figure 1 (the link being connected with the pole chain or other part of a vehicle
and the shackle; with the harness) if the horse falls the 'bush or collar is pushed
upwards against the springh until the stud or pin is clear of the notch at that
end of the slot when the bush or collar g is partially turned round on the head 3
or shank c until the stud or pin is opposite to the notch at the other end of the
slot or in the position seen in figure 2 when the bush or collar g locking itself on
the stud or pin by the recoil of the spring ħ the square shaped gap m through the
circumference of the bush or collar g'will be clear of or allow passage to the lip or
lug e at the upper end of the lever part b of the link and the strain of the harness 4
on the lower curvature of the lever part b will thereby instantly cause the latter to
fly outwards on its hinge or fulcrum d and so disengage the harness from the pole
chain or other part of the vehicle and release the horse.

page_text: On closing the parts a and b of the link and reversing the action of the bush or
collar g the horse and harness can be again connected with the vehicle.
By our invention safety is ensured to horses from the many accidents arising
from the old clumsy method of fastening now in use.
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
The construction and use of a slip link formed in two parts combined with
apparatus for locking and separating or releasing the same substantially as and for
the purpose hereinbefore described and illustrated by the accompanying drawing.
