SPECIFICATION.
An Improved Dog Slip.
1, FREDERIC THOMAS KERSLAKE BAKER, of 88 Fleet Street, in the County
of London, Gun Maker, do hereby declare the nature of this invention to be as
follows:-
:―
My invention relates to the improved construction of a "slip," for releasing
retrievers, greyhounds and other dogs, for sporting or other purposes, and the main
object of the said invention is to construct a "slip" in such manner that it can be
readily attached to a dog by a single motion of one hand only. "Slips" as
heretofore constructed cannot be operated in such a manner.
66
My improved "slip" consists substantially of a short tube, or barrel, provided at
one end with a hook for attachment to the ordinary ring on the collar of the dog,
and at the other end with a loop to receive a strap in the usual way. The aforesaid
hook slopes away from the barrel, for a reason to be presently described.
Within the tube, or barrel, is placed a sliding bolt, one end of the said bolt is
chamfered, and forced against the inside of the hook by a spring, the other end
being provided with a ring, or eye, to receive a cord. The device can instantly be
applied to the ring on a dog's collar with one hand, by merely entering the point of
the hook in the ring and exerting a slight pressure to cause the ring to pass by the
chamfered end of the bolt. As soon as the ring has passed the bolt, the latter
shoots out again and securely locks the ring within the hook.
To release the dog the bolt is drawn clear of the hook by means of the cord, and,
as the hook slopes away from the barrel, as previously described, it instantly falls
out of the ring and the dog is free.
1
To ensure the chamfer on the end of the bolt being always presented in the right
direction, a flat may be formed on the bolt and a pin be inserted transversely
through the barrel to bear thereon, or any other suitable means may be employed
to prevent the bolt rotating in the barrel."

COMPLETE SPECIFICATION.
An Improved Dog Slip.
I, FREDERIC THOMAS KERSLAKE BAKER, of 88 Fleet Street, in the County
of London, Gun Maker, 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:-
My invention relates to the improved construction of a "slip," for releasing
retrievers, greyhounds and other dogs, for sporting, or other purposes, and the main
object of the said invention is to construct a "slip," in such manner, that it can be
readily attached to a dog, by a single motion of one hand only. Slips as
heretofore constructed, cannot be operated in such a manner.
In the accompanying sheet of drawings;
Fig. 1 is an external plan of my improved "slip," and,
Fig. 2 is a sectional clevation of the same through the line A A in Fig. 1.
,,
B is a short tube or barrel, provided at one end with a hook C, for attachment to
the ordinary ring on the collar of the dog, and at the other end with a loop D, to
D021

page_text: receive a strap in the usual way. The said hook and loop are preferably made in
one piece with the barrel B, as shewn.
Within the said barrel is placed a sliding bolt, one part E of the said bolt is a
sliding fit within the. barrel, while the remainder E₁, is of reduced diameter, and
slides within a collar F, fitting into the barrel and secured in place by a set screw H,
the point of which enters a recess in the collar. A helical spring J is placed
around the reduced part E of the bolt, its ends abutting against the collar F and
the shoulder formed by the enlarged part E, so that it keeps the end of the bolt
forced out against the hook C as shewn, the said end is chamfered as shewn at E²,
while the other end is provided with a ring K, for the attachment of a cord.
The device can instantly be applied to the ring on a dog's collar, with one hand,
by merely entering the point of the hook C in the said ring and exerting a slight
pressure to cause the ring to pass by the chamfered end E2 of the bolt. As soon as
the ring has passed the bolt, the latter is shot out again by means of the spring J,
and securely locks the ring within the hook, while no amount of pulling by the dog
can tend to force the bolt back and release the ring.
To disengage the dog, it is merely necessary to pull the cord attached to the
ring K, and so withdraw the bolt, and as the inner edge C¹ of the hook slopes away
from the barrel, as clearly shown in Fig. 2, it must instantly fall out of the ring on
the collar, leaving the dog free. The sloping of the hook in this manner forms
therefore an essential and most important part of my invention.
To prevent the bolt rotating within the barrel, so that the chamfer E' shall be
always presented in the right direction, a piece may be cut out of the enlarged
part E of the bolt, leaving a flat E³, and a pin L be inserted transversely through
the barrel, to bear thereon, or any other suitable means may be employed to prevent
rotation of the bolt.
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
66
1. In a dog slip," a hook C having an outwardly sloping inner edge C¹, and a
spring actuated sliding bolt E, bearing against the said edge, substantially as set
forth.
<<
2. In a dog slip," a hook C having an outwardly sloping inner edge C¹, and a
spring actuated bolt E, with a chamfered end E³, bearing against the said edge,
substantially as set forth.
*
3. In a dog slip," a hook C having an outwardly sloping inner edge C¹, a
barrel B attached to said hook and having a loop D and containing a bolt with
part E, sliding within said barrel, reduced part E', sliding within collar F, gap in
part E and stop pin L passing through said gap, chamfered end E³, pressed by a
spring J against said edge C¹, and a ring K, substantially as set forth.
