PROVISIONAL SPECIFICATION.
Improvements in and connected with Swivel and Releasing Hooks.
I, WILLIAM HENRY WILSON, of 58 Mountpottinger Road, Belfast, Ireland,
Ironmonger, do hereby declare the nature of this invention to be as follows :-
The object of my invention is to provide a hook which will answer the same
purpose as a spring hook and having the advantage in not having or requiring a
spring to keep it closed.
In the ordinary spring hook the joint which allows the part to open is in the
neck of the hook and therefore it is opened to the inside. Whereas in these hooks
the joint is at the point where the end of the part that opens in the ordinary spring
hook falls against, and therefore it opens to the outside which allows it to hook a
larger article than the spring hook.
The part that opens in these hooks has two claws which fall into a place on the
neck of hook which is hollowed for the purpose, and having a protection in the
hollow of the neck with a corresponding hollow at the claws, the protection keeps
the claws steady in their place when the hook is closed, as the claws are dovetailed
as it were into the neck of hook.
The part that opens in the hook is kept closed by a link or square end as the
case may be, by having attached to them two flat pieces fitting into the neck of
hook and parallel to hook joined to neck of hook by a pivot which will allow it to
swing backwards or forwards allowing the top of the flat piece to come upon the
claws which will keep them from opening when the link or square part is parallel
to hook, the flat piece has two hollows at the side which when the link is parallel to
hook the hollows are at right angles to hook and when the hook is required to be
opened the link part is brought up at right angles to hook bringing the two hollows
opposite the two claws of the hook, which then allow it to open.
These hooks can be made double or single.

COMPLETE SPECIFICATION.
Improvements in and connected with Swivel and Releasing Hooks.
I, WILLIAM HENRY WILSON of 58 Mountpottinger Road, Belfast, 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—
This invention relates to an improved construction of safety hooks to be used
in place of that class of safety hooks in which a portion is pivotted to the main
hook, and opens inwardly being held closed by a spring; by this arrangement the
space for the admittance of the article to be hooked is reduced by the thickness of
the pivotted part. By my invention, I make this pivotted part to open outwardly
and so admit a larger article the opening part being secured when closed without
the aid of a spring as hereafter described.
To enable my invention to be properly understood I will proceed to fully
describe the same with aid of the accompanying drawings.
Figure 1 is one arrangement of the above described hook closed.
Figure 2 side view of same.

page_text: Figure 3 showing a portion of the same turned on one side to admit of the
pivotted portion being opened outwardly.
Figures 4, 5, 6, 7, 8, and 9 illustrate various forms and positions of the said
hooks.
A is the hook proper, B the outwardly opening piece the free end of which is
made with a tongue or claws C to pass through ward openings D upon the part. E,
this part is pivotted to the shank of the hook which is recessed to allow the claw
part C to come flush with the other part so that the pivotted part E can turn round
over it by which means the part B is locked, and this locking is secured so long as
there is any strain upon the shackle part G of the hook. For further security
this latter part may be divided in two as at Figures 6 and 7 the rope or chain
passing through both so that any strain draws these parts together and holds the
part E over the claws C.
To open the hooks it is only necessary to turn the part E at right angles to the
hook as at Figure 3 when the pivotted part B can be opened outwardly as shown
by dotted lines at Figure 1. It will readily be understood that the part B need
not have its free end formed as a claw C nor need the part E have openings D to
enable the part B to be secured as described by the turning of part E. Figures 4
and 5 show how hook is attached to a strap or band, the part ( being altered to
that shown in these figures at G₁. Figures 8 and 9 show this invention applied to
ring hooks arranged for attachment to a wall or otherwise to open the ring it must
be laid down flat as shown by dotted lines.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. A safety hook having the hinged part B arranged to be secured and opened
by turning a pivotted part to cover or free the end of part B, as described and
illustrated by the accompanying drawings.
2. A safety hook or ring having the hinged part B arranged to be secured or
opened by turning the ring or hook part A, as described and illustrated at
Figures 8 and 9.
