JOHN HOBART ARMSTRONG Chartered Accountant 82 Eldon Street Newcastle-on-
Tyne, do hereby declare the nature of my invention for SLIPPING DOGS OR OTHER
ANIMALS IN PERSUIT OF GAME, &C 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 this invention is the construction of a slip-hook or coupling
connected with a cord or other leash, and so designed that dogs or other animals
may be retained or instantly released at the will of the person having them in
charge.
The improvements may be thus described :-The hook, at its shank end is shaped
into a ring to which a cord or other leash is securely attached. At a point a little
above the centre of the bend of the hook is a hinge allowing the point, or slip
portion, of the hook to move freely either towards or away from the shank end of
the hook The point end of the hook is of greater length than the shank end, and
is so shaped as to fit closely against that portion of the cord or leash immediately
attached to the shank.
The point end is kept in position when the slip book is closed, by a circular
collar or thimble running freely upon the leash, and wide enough in diameter to
encircle both the leash, and point of the hook.
"
The collar or thimble is hollowed out or cupped in a pear" shape the diameter
of the mouth being less than that of the interior. The extreme point of the hook
is slightly bent outwards, forming a nose and fits into the cupped portion of the
thimble when the latter is placed in position by the slip being closed. By this
means the tension caused by pressure on the slip, tends to press the nose (formed
by bending the point of the hook) into the cupped or hollow portion of the thimble
and thus secures it in its place-To the thimble is attached a second cord which is
carried back to the hand of the person controlling the leash, and which when
pulled draws back the thimble, at the same time releasing the point or slip end
of the hook and thus instantaneously freeing the collar of the animal to be slipped.
For the better illustration of my invention I have annexed hereto a drawing of
about life size with letters of reference marked thereon.
A slip hook having at its shank end (a) a ring to which is attached a rope or
other leash (f) the hook having a hinge (b) a little above the centre of the bend
of the book which allows the point end of the hook (e e) to move backwards or
forwards (see dotted lines).
The "point" end being of greater length than the "shank" end it rests when
shut upon a portion of the leash being held in position by a collar or thimble (cc)
running free upon the leash and which is wide enough at the mouth to encircle
both the leash and point end of the hook. The thimble is hollowed as shewn by
dotted lines, the nose formed by bending backward the extreme point of the hook
being shewn in a similar manner. The thimble is drawn back at will by a second
cord (d) which liberates the point end of the hook, allowing it to fly back and so
release the animal to be slipped.

page_text: 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:-
1. The application of a collar or thimble in securing the slip and the absence of
any spring or other part likely to be affected by or to failure in use.
2. The novel combination and construction of the various parts by which the
slip can be used either for the purposes for which it is intended or in the place of
a buckle or other fastening for a leash.
8. The arrangement of the thimble whereby the greater the strain on the alip
the more secure it becomes.
