Improvements in Safety Hooks for Signal Halyards for Marine and
other Purposes.
I James Alfred HALLETT of 7 Saint Martins Place Trafalgar Square in the County
of Middlesex Navy Agent and Banker (a communication from abroad by Lieutenant
Hugh Blencowe Rooper of H.M.S. Lily Bermuda) do hereby declare the nature of
said invention for "IMPROVEMENTS IN SAFETY HOOKS FOR SIGNAL HALYARDS FOR
MARINE AND OTHER PURPOSES to be as follows:
23
This invention has for its object improvements in safety hooks for signal halyards
for marine and other purposes and consists of a pivotted hook. The opening on the
one side being closed by a hinged part which opens outwardly and in its normal position
closed by an indiarubber band or other suitable spring and the link which is introduced
therein is made of a taper shape the narrowed end of the link being connected to the
hook aforesaid and the larger end to receive the signal halyard.
This device is held or suspended by a swivel ring or hook in the usual manner. The
advantage of an indiarubber ring over a steel or brass spring is that they can be more
readily applied and with less liability to get out of order. The hook and the closing
piece are advantageously provided with a recess to receive the indiarubber band.

Improvements in Safety Hooks for Signal Halyards for Marine and
other Purposes.
I JAMES ALFRED HALLETT of 7 St. Martins Place Trafalgar Square in the County
of Middlesex Navy Agent and Banker (a communication from abroad by Lieutenant
Hugh Blencowe Rooper of H.M.S. Lily, Bermuda), do hereby declare the nature of
said Invention for "IMPROVEMENTS IN SAFETY HOOKS FOR SIGNAL HALYARDS FOR
MARINE AND OTHER PURPOSES," and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This Invention has for its object improvements in safety hooks for signal halyards
for marine and other purposes and consists of a pivotted or swivel hook, the opening
on the one side being closed by a hinged part connected to the ring and opens
outwardly.
It is kept in its normal or closed position by an india rubber band or it may be any
other suitable spring and the link which is introduced thereon is in some cases made of
a taper shape, the narrowed end of the link being connected to the hook aforesaid and
the larger end to receive the signal halyard. This device is held or suspended by a
swivel or jointed ring or hook in the usual manner.
The advantage of an india rubber ring over a steel or brass spring, is that they can
be more readily applied and with less liability to get out of order, but a coiled steel or
other spring may surround the hook. The hook and the closing piece are advan-
tageously provided with a recess or equivalent device to receive the india rubber or
other band..
In the accompanying drawings are shewn two views one in part side elevation at
Fig. 1 and in end view at Fig. 2 in these figures 'a' is the hook and swivelled or other-
wise suitably connected to the ring 'd, as by the means represented at a¹. To a part
of the hook a' or in some cases it may be to the ring, the closing piece 'b' is hinged at 'c,'
shewn in the Figure 1. The india rubber or other clastic or spring band '" surrounds
the hook a and the hinged closing piece 'b, and is retained in its position by the
projections e on the hook or the part 6, or it may be effected by suitable grooves.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I would have it under-
stood that I do not confine myself to the ring or the hook, as the same may be hinged
or swivelled or otherwise connected, but what I do claim is :-
⚫ In safety hooks for signal halyards, the means herein described and illustrated,
operating substantially in the manner and for the purposes set forth.
