SPECIFICATION.
An Improved Slip Hook for Instantly Releasing a Fallen Horse
from the Shafts of a Cart, or from the Shafts of a Waggon, or
from the Pole of a Waggon.
FREDRICK SHEPHERD, 9, King's Row, Horsleydown, S.E. Smith and Farrier, do
hereby declare the nature of this invention to be as follows:-
The slip hook is composed of five pieces, the box, or fraine, the hook, the sliding
catch, the two V springs. The hook which is very long, is pivoted at one end of the
box, the other end of the hook is made with a catch which, when the hook is closed
meets with a sliding catch inside the box; then the sliding catch is held firmly and
securely in its place by a V spring. The advantage of the hook being long is, that
the weight or pressure is taken off the catch & put on to the pivot, thus enabling the
sliding catch to be moved easily when the weight or strain is on the hook. In the
centre of the box and the sliding, catch is a hole or slot for the insertion of the finger
by which it can be gently pulled back, and when the sliding catch is thus pulled back
the hook is then immediately released and is thrown open by another V spring, so that
the chain or any other thing to which the hook is connected slips off and the horse is
at liberty.
It is also
The slip hook is fitted to pole or hames with a coupling, or shackle.
fitted on the hames with a bolt or rivet as a draft hook. It is fitted on to the bar of
the shafts with bolts where the draft hook is not used on the hames.
The slip hook can also be fitted to any other part of the harness. When the hook is
closed it is impossible for dirt to get into the box, so that it cannot get clogged, nor
the springs corroded as is the case of some kinds that are in use.

COMPLETE SPECIFICATION.
An Improved Slip Hook for Instantly Releasing a Fallen Horse
from the Shafts of a Cart, or from the Shafts of a Waggon, or
from the Pole of a Waggon.
FREDRICK SHEPHERD, 9, King's Row, Horsieydown, S.E. Smith and Farrier, do
hereby declare the nature of this invention and in what manner the same is to be
perforined to be particularly described and ascertained in and by the following
statement-
I construct of iron and steel an improved slip book. I make it of six pieces,
namely, the box or frame, the sliding catch, the hook and two V springs. The box
or frame is hollow made in two pieces and fixed together with three screws. I make
the hook very long and harden it at the pivot hole and pivot it at one end of the box,
or frame with a steel pivot to prevent it from soon wearing. At the other end of the
hook I make a catch, which, when the book is closed meets with the sliding catch
inside the box or frame; then the sliding catch is held firmly and securely in its place
by one of the V springs. I make the pivoted hook long to take much strain from the
catch end of the hook and put more on to the pivoted end. I will now refer to the
drawings. The box or frame is hollow made in two pieces which are marked & b
as shown in Fig. 1. Fig. 2. and Fig. 3. I fix the box or frame together with three
screws and the pivot as shown in Fig. 3. At one end of the hook c, I make a catch,
as shown in Fig. 2. which when the hook c is closed, as shown in Fig. 1. meets with
the sliding catch d inside the box or frame; then the sliding catch d is held firmly

page_text: and securely in its place by the V spring f as shown in Fig. 1. I make the pivoted
hook c as shown in Fig 1. long to take much strain from the catch end of the hook c
and put more on to the pivoted end, see Fig. 1. and Fig. 3. Thus the sliding catch d
can be moved easily when the whole strain of the horse is on the hook. I make a hole
in the box or frame and the sliding catch, as shown in Fig. 3. for the insertion of the
finger, by which the sliding catch can be pressed lengthways the hook. When the
sliding catch d is thus pressed the catch end of the hook c is released and thrown open
by the spring e which I place at the back of the hook c as shown in Fig. 1. and
Fig. 2.
In Fig. 2. I have not shown the hook c wide open, but the hook c does fly
wide open, then immediately the chain or any other thing with which the hook is
connected slips off and the horse is at liberty. My Improved slip hook when closed,
as shown in Fig. 3. is so constructed that dirt is prevented from getting into the box
or frame, thus the springs are protected. I fix my Improved slip hook to the hames
as a draft hook with a bolt or rivet, see Fig. 5. and Fig. 6. I fix my Improved slip
hook to pole or hames with a coupling as shown in Fig. 4. I also fix iny Improved
slip hook to the bar of the shafts with a bolt or rivit. My Improved slip hook can be
fitted to other parts of the horse's harness, for instance the breetching. In each of
these slightly different patterns of the box or frame adapted merely to be fitted on
different parts of the horse's harness, the inside action is exactly the same as shown in
Fig. 1. and Fig. 2.
I am aware that there are already slip hooks in use, but the action in them is
different from the action in my Improved slip hook. I make my pivoted hook long
as shown in Fig. 1. those slip hooks now in use have short pivoted hooks. I make
the catch end of my pivoted hook, as shown in Fig. 2. quite different from the catch
ends of those now in use. Slip hooks now in use have no V springs to act on the
pivoted hooks; my Improved slip hook has the V spring to act on the pivoted hook
as shown in Fig. 1. My Improved slip hook has the sliding catch, and the V spring
acting on that sliding catch; slip hooks now in use have neither the sliding catch nor
the V spring.
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
