COMPLETE SPECIFICATION.
An Improved Hook, suitable for Use in connection with Chains,
Shipping-tackle, and the like.
I, JOHN VENABLES of the Firm of Samuel Venables and Son, Spring-hook
and Chain Manufacturers of Shaw Street, Walsall in the County of Stafford
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 consists in the combination and arrangement of parts hereinafter
described forming and constituting an improved hook, suitable for use in connection
with horse-chains dog-chains and other chains and also suitable for use in connection
with shipping-tackle and also suitable for use in small sizes in connection with the
make-up of watch-chain and other small chains.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used.
Figure 1 represents a front view of closed hook.
Figure 2 represents a side view of Figure 1.
Figure 3 represents a front view of
open hook.
Figure 4 represents a side view of Figure 3.
Figure 5 represents a detailed front view of hook.
Figure 6 represents a side view of Figure 5.
Figure 7 represents a front view of hook covering-arm.
Figure 8 represents a side view of Figure 7.
Figure 9 represents a front view of link.
Figure 10 represents a side view of Figure 9.
Figure 11 represents an enlarged diagram shewing position of flattened side of
link moved into position that would enable the link to pass out through the slot in
hook covering-arm.
Figure 12 represents the link moved so as to present the full unflattened side of
link to the opening in hook covering-arm.
In carrying out my invention I provide the hook a as shewn at Figures 1234
and as shewn in detail in front view at Figure 5 and in side view at Figure 6.
I next provide the covering-arm as shewn at Figure 7 and in side view at
Figure 8.
I next provide the link e as shewn at Figures 1 2 3 and 4 and as shewn in detail
at Figures 9 and 10.
One side or end of the link c is formed of a D shaped section as shewn at d
Figures 9 and 11 or of any other dimensions and configuration suitable to pass
through the locking slot e provided in the covering-arm.
The hook a covering-arm band link c would be connected together in the
following manner.
C
The link would in some cases be permanently connected to the hook a by
passing the link through the link-hole h before the link is welded together,
although I have shewn a perfect jointless link c nevertheless it will be apparent
that any class of link either welded or open at the joint can be utilized, the novel
part of the link consisting of its reduced or flattened part d or other equivalent
narrowed part.
I next take the covering-arm band place it in position over the hook a as shewn
at Figure 4 and then pass a stud or rivet j through the stud-holes f and 9; in some
Pl

page_text: cases I prefer to cast or otherwise produce the stud either on the hook or on the
hook-cover in lieu of using a loose stud j.
I next move the covering-armb on its stud or rivet j as an axis until the slot e
travels over the radial path shewn in dotted lines at Figure 4 and onwards over
the reduced part d of link, the link is then moved from the side position shewn at
Figures 3 and 4 into its end position as shewn at Figures 1 and 2, thus moving the
full part of link over the internal entrance to slot e and thereby locking the link
within the link-hole of covering arm as shewn in the enlarged sectional broken off
view Figure 12 and as also shewn at Figures 1 and 2; the lip of the hook a is
beviled and stepped at 1 to correspond with the stepped and bevilled end m of
covering-arm b, such bevilling being provided to form a stop-joint and thus prevent
the covering-arm passing over the vertical intersection with hook a.
Each of the separate parts herein before described can be produced by the casting
process, forging process, stamping process, or by other suitable mechanical means
in accordance with the strength and size of the complete article.
I am aware that a variety of hooks have been made each with a covering arm
technically known as the spring-book closing arm. I am also aware that a hook has
been made with a covering arm actuated without a spring, all of such covering
arms have been connected to the hook part in such a manner as to move off the
hook (to uncover the hook-point) in a vertical direction thus offering but a small
opening through which to pass a link of chain, a rope or other lifting appliance.
In contradistinction to such old style method of adjusting the covering-arm of a
hook I by my improved method of connection and adjustment in an horizontal
position, present to view the point of hook and the full width of the opening over
hook-point so that a rope or chain of larger dimensions can be readily passed over
the hook than could be done by the use of a hook with a vertically connected
covering-arm.
Instead of filling or otherwise removing a portion of the link-side or link-end to
form the narrow part d I in some cases prefer to compress the link as a means of
forming the narrow part as shewn at n Figure 10, in such cases the compressed
part would bulge out at the sides and so give to the link a strength at the narrow
part equal or nearly equal to the strength of the main part of the link, this com-
pressing method is more particularly necessary when the hooks are made in large
sizes to connect to heavy chains, cables, and such like.
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 :-
1st. The making of a book with a hook-cover and link to form and forming a
lockable covered hook for use in connection with horse-chains dog-chains watch-
chains and other chains and also for use in connection with shipping-tackle as
illustrated and described in relation to figures one to twelve.
2nd. In the hook-cover of a covered hook the providing of a locking-slot through
which to pass the narrow part of a link to lock or retain the link within the
shank-end of hook-cover as illustrated and described in relation to figures four
eleven and twelve.
3rd. In the link of a covered hook the providing of a narrow part of smaller
dimensions than the main part to enable such narrow part of link to be passed
through a slot provided in the cover of the hook so that any portion of the main
full part of link can be moved into position as shewn at figure twelve to lock or
secure the hook-cover over the link.
