Improvements in Spring Hooks.
We, HENRY WILLIAM LEY, of 17 Charing Cross Road, in the County of
Middlesex, Mechanician, and ARTHUR GREVILLE BAGOT, of Fisherwick, in the
County of Staffordshire, late Captain 60th Royal Rifles, do hereby declare the
nature of this invention to be as follows:-
Our improvements refer more particularly to such hooks as comprise a body, a
tongue and a spring.
In accordance with our invention we make the hook-body from sheet-metal
stampings, that is to say we make the said body composite.
In carrying our invention into practice we may, for example, employ two
hook-shaped stampings each preferably formed with a recess. Each of these
stampings is the inverse of the other and the aforesaid recesses are so fashioned
that when the two stampings are rigidly united to form the hook-body, a chamber
will be produced which will serve to receive a suitable axle for carrying the
tongue and which will also afford ample room for the reception and action of
the tongue-spring.
Hooks constructed in accordance with our invention are specially suitable for
"sail-hanks."

Improvements in Spring Hooks.
We, HENRY WILLIAM LEY, late of 17 Charing Cross Road, but now of
2 Whitcomb Court, Piccadilly Circus, in the County of London, Mechanician, and
ARTHUR GREVILLE BAGOT, of Fisherwick, in the County of Stafford, late
Captain 60th Royal Rifles, 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 :-
Our invention relates to spring hooks and an important feature thereof is the
construction of such hooks with composite bodies preferably formed from sheet
metal stampings, whereby such hooks can be made light and strong.
Hooks made according to our invention are moreover easy to handle, and are
certain and reliable in their action.
In carrying our invention into practice we may, according to one arrangement,
combine together two hook shaped stampings each having a recess in one side
thereof, one stamping being the converse of the other, so that when the two stampings
are rigidly united they will form a hollow hook body, with a cavity or chamber
for the reception of the tongue and spring. It will be obvious however that the

page_text: said hooks can be formed in a variety of ways without departing from the nature
of our invention, an essential feature of which is the composite formation of the
hook body.
In order that the invention may be readily understoood we will proceed to more
fully describe the same by reference to the accompanying drawings which illustrate
various forms of our improved hook.

shown in Figures 1 to 10, but made up of an inner stamping with recesses on both
sides and outer stampings which fit into these recesses.
Figures 22 and 23 are cross sections taken respectively on the lines y' y' and y² y
of Figure 20.
Figures 24, 25 and 26 are respectively side, back edge, and plan views of a
construction of hook provided with special means for operating the tongue.
Figures 27, 28 and 29 are detail views thereof drawn to a larger scale.
Figure 30 is a side view of another construction of hook provided with special
means for operating the tongue and in which the tongue is opened outwards.
Figures 31, 32 and 33 are detail views of this last construction.
Throughout the drawings the same letters of reference indicate corresponding
parts.
Referring more particularly to Figures 1 to 10, a are the stampings which form
the body of the hook. They are advantageously made of steel and are galvanised
when protection is required from the corrosive action of water. Each of them
is, on one side, set over or flanged at the edges a¹ and provided with a shoulder as
ata, the portion a² beyond the shoulder being flat and the overset and shoulder
being of such a depth that when the stampings are placed together with their
edges a¹ and flat portions a² in contact to make up the hook body, a chamber
is formed immediately above the shoulder. The turn-over at the edges of the
stampings adds very greatly to their rigidity and strength. b is the tongue of
the hook which is pivoted on a pin c secured between the two stampings a. This
tongue is acted upon by a spiral spring d tending to keep it in the position shown
in full lines, and serving to return it to this position after it has been forced back
or opened as indicated in dotted lines (Figure 4). The said spring is coiled around
a pin e, secured between the stampings a and its outer extremity is hooked as

page_text: shown at d and engages with a projection 6 on the tongue. It will be seen that
the chamber above referred to between the stampings a serves very advantageously
to accommodate the said spring and the lower part of the tongue. The flat
portions a of the stampings when brought together as explained can then be
securely united by a pair of thimbles f which are passed through eyes or
apertures g formed in the said portions a' and have their edges folded over or
clinched as seen more clearly in Figures 2 and 3. The eyes 9 serve also for
securing the hooks in position as required by means of cords or lashings in the
ordinary manner.
Obviously however these hooks instead of having eyes may be formed with a
curved or fluted T-piece which may be bound lengthwise against a rope.
The hook shown in Figures 11 to 15 is mainly formed of a single flat stamping a
and the tongue & is forked at each arm of the fork carrying a boss o cylindrical
projection 63 analogous to a hollow trunnion. At each side of the stamping a is.
secured, by rivets or otherwise, a cheek & (see Figures 11 and 13) having an
aperture adapted to receive the projections 6. Between the arms 6 of the fork
and around a square pin e¹ secured between said arms, is arranged a coiled spring d
one end of which is secured to the said pin while the other end bears at d² against
the body of the hook, as seen more clearly in Figure 14. This spring serves the
same purpose as that in the hook above described, that is to say it tends to keep the
end of the tongue against the hook as indicated in full lines Figure 11 and to return
it into this position after it has been moved back or opened. The stamping a is
formed with eyes or apertures g for enabling it to be secured in place. It is to be-
noted that in this arrangement the cheeks form a portion of the composite body of:
the hook.
The hook illustrated in Figures 16 to 19 has its body formed of two outer
stampings a and an intermediate and thicker stamping a* which is cut away, as
indicated by the dotted line a to form a space into which the tongue 6 of the hook
can fall back. This tongue is provided with a thumb piece and projecting
from an hollow boss or cylinder 6 which serves as a spring barrel to receive a
spring d connected at one end to a pin e¹ secured between the outer stampings a..
The hollow boss is wider than the space between the stampings a however, and
the latter are formed with swellings or enlargements a to receive the ends of the
said boss, so that the enlargements form bearings in which the tongue turns.
this hook the eyes g are formed in the intermediate stamping a".
The hook shown in Figures 20 to 23 has its body formed of three stampings, but
in this case the intermediate stamping a* has flanged edges and recesses, in which
latter the outer stampings a are inserted as seen more clearly in Figures 22 and 23.
In this hook the tongue is arranged in a manner similar to that shown in Figure 4,
and to perinit of such arrangement the intermediate stamping is cut away as
indicated by the dotted line a' in order to form a recess or cavity between the outer
stampings a.
In the arrangement shown in Figures 24 to 29, wherein special means are
provided for operating the tongue, the body as before consists of three stampings,
the intermediate one of which is cut away leaving a space between the outer
stampings as indicated by the dotted lines Figure 24 for the operating mechanism
which is shown to a larger scale in Figures 27, 28 and 29. This operating
mechanism comprises a spring barrel i having a series of teeth engaging with
rack teeth at one end of a bolt k. The tongue & has also a series of teeth engaging
with rack teeth at the other end of the bolt. At one side of the bolt and in gear
with lateral teeth thereon, is arranged a partly toothed disc l enclosed in a
suitable casing m and mounted on a vertical axle 1 in said casing, which latter -
communicates with the chamber in the book body by means of an opening m*.
A finger piece or pusher a projects from the side of the hook and its stem a is
connected to a crank pin on the disc / so that when the said pusher is moved in
or out, the disc is rotated and operates the bolt k. In the present example of hook.
the parts are so arranged that the spring barrel normally draws the bolt k to the

page_text: left (Figure 27) and so keeps the tongue b closed. When however the pusher n is
forced inward, the disc is rotated and moves the bolt to the right so turning back
and opening the tongue, which will be again closed by the spring when the pusher
is released.
In the arrangement shown in Figures 30 to 33, a bolt k is also employed for
operating the tongue b but in this case it has only one set of teeth which engage
with corresponding teeth on the tongue. One end of the bolt works in an aperture
in a plate and the outer end is enlarged. at and forms a slide which works
upon the surface a of the body of the hook and between the stampings a. Around
the bolt is arranged a spiral spring abutting at one end against the plate k and
at the other end against a shoulder on the bolt, the outer stampings of the
hook body being enlarged or swelled outward to accommodate the said spring, as in
Figures 32 and 33.
In this case the tongue of the hook is arranged to open outwardly, and is when
closed connected with the bolt by means of a pair of hook-like teeth 6, which
come together after the ordinary teeth on the tongue and the bolt have passed
out of engagement as shown in. Figure 31. The purpose of these hook-teeth is to
prevent the tongue being opened by direct pressure thereon, as they prevent rotary
movement of the tongue until the bolt has been pushed back a sufficient distance to
disengage them, when the ordinary teeth on the said bolt come into engagement with
those on the tongue and effect the opening of the latter. It will be observed that
in the example shown in these figures, the innermost tooth k* on the bolt is made
larger than the others, and engages in a corresponding recess d in the tongue, the
purpose of this being to ensure the engagement of the teeth on the said bolt and
tongue.
Spring hooks constructed according to our invention are adapted for use as sail
hanks although they are obviously applicable for various other purposes for which
spring hooks are suitable.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A spring hook, in which the body is composite that is to say formed of two or
more separate metal pieces or stampings, substantially as described and for the
purposes specified.
2. A composite spring hook constructed as herein before described with reference
to Figures 1 to 10; Figures 11 to 15; Figures 16 to 19; Figures 20 to 23;
Figures 24 to 29; or Figures 30 to 33 of the accompanying drawings.
