I, JAMES GRIFFIN, of High Street, Uckfield, Gentleman, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in or connected with mechanism for the
lowering and releasing of ship's boats, said mechanism being more particularly
intended for use in connection with my Improvements in raising and lower-
ing ship's boats" Patented to me on the 7th. May, 1896, and numbered 9729,.
while the releasing hook hereinafter referred to is similar in every respect to that.
described in the specification of my former Letters Patent No. 16687, 28th. July,
1896, and entitled "A new or improved, device or appliance for use in connection
with the releasing of ship's boats and the like."
The object of this invention is to enable the boat to be lowered by one of the
occupants instead of a man being necessary to operate the lowering gear from the
vessel or ship, while when the boat has been sufliciently lowered it can be auto-
matically released, and by this means the whole of a ship's crew may enter the
boats before casting off, thus doing away or obviating the risk of the boat being
stove in against the ship's side while waiting for the man usually employed in
operating the lowering gear as has hitherto been the case.
In carrying my invention into practical effect, I connect to one end of the brake
lever described in connection with my former Patent No. 9729 and above referred
.to, a suitable rope or cord, said rope or cord leading to a clip and sheave in the.
davits and from thence to the boat where it may be made fast in any suitable
manner. By this means any person within the boat is enabled to control the brake
of the lowering gear and to regulate the operation of same and the lowering of the
boat as required.
In order that the boat may be released when sufficiently lowered I provide two
ropes or cords secured one to each releasing hook, which is of a similar construction
to that described in my former Patent No. 16687 hereinbefore referred to, the end
of said cords or ropes passing over a suitable pulley or the like conveniently
arranged so that by pulling a third cord or rope connected to the free ends of the
aforesaid two ropes or cords, the two releasing hooks, one at each end of the boat,,
are simultaneously operated, and the boat released therefrom.

I, JAMES GRIFFIN, of High Street, Uckfield, Gentleman, 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 improvements in or connected with mechanism for the
lowering and releasing of ship's boats, said mechanism being more particularly in-
tended for use in connection with my "Improvements in raising and lowering
ship's boats" Patented to me on the 7th. May, 1896, and numbered 9729, while the
releasing hook hereinafter referred to is similar in every respect to that described
in the Specification of my former Letters Patent No. 16687, 28th. July, 1896, and
entitled "A new or improved device or appliance for use in connection with the
releasing of ship's boats and the like."
The object of this invention is to enable the boat to be lowered by one of the
occupants, instead of a man being necessary to operate the lowering gear from the
vessel or ship, while when the boat has been sufficiently lowered it can be easily
released, and by this means the whole of a ship's crew may enter the boats before
casting off, thus doing away or obviating the risk of the boat being stove in
against the ship's side while waiting for the man usually employed in operating
the lowering gear, as has hitherto been the case.
I
In order that my invention may be fully understood, I will now proceed to de-
scribe same with reference to the accompanying drawings in which Fig. 1 is a
side elevation of a part of the mechanism and my improved means for regulating
the lowering of the boat, and Fig. 2 is an elevation or diagrammatic view showing
the means I employ for releasing the boat.
In carrying my invention into practical effect, I connect to one end of the brake
lever, 2 described in connection with my former Patent No. 9729 and above re-
ferred to, a suitable cord, rope, or flexible connection, a which passes over sheaves
or pulleys P, P', p³, and p³, two of which are conveniently arranged or carried on
the davit d, while one is carried by the frame f and another suitably pivoted or
connected to the brake lever c², the end of the said rope or flexible connection then
passing into the ship's boat 6 where it may be made fast in any convenient
manner.
By this means it will readily be seen that any person within the boat is enabled
to control the lowering gear by pulling the cord or flexible connection a which
applies the brake, and thus regulate the lowering of the boat as desired.
In order that the boat may be released when sufficiently lowered, I provide two
cords or ropes c, c¹, secured one to each releasing hook h, h', which is of a similar
construction to that described in the Specification of my former Letters Patent No.
16687 A.D. 1896 hereinbefore referred to, the ends of these cords, ropes or flexible
connections being spliced or connected to a third cord, rope, or the like g passing
over a pulley 61 of the pennant 2 which is suitably suspended between the
davits d, d, as shown.
The cord or rope g passes down into the boat which is indicated by dotted lines
so that when the said boat has been sufficiently lowered it is only necessary to
sharply pull the rope or cord g which simultaneously "trips" the hooks h, h', thus
releasing the boat at both ends.
I do not restrict myself to the exact form or arrangement of the pulleys as shown
in Fig. 1 as they may be arranged in other suitable positions if required.

page_text: 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:-
1. In mechanism for lowering ship's boats the use of a suitable cord or flexible
connection such as a, having one end secured to the brake lever c³ of the lowering
gear and being led over suitable guiding pulleys to the boat 6 for the purpose of
enabling the lowering gear and the lowering of the boat to be regulated by a person
within same, substantially as set forth.
2. In mechanism for releasing ship's boats, the use of two cords, leaders or
flexible connections c, c¹, the ends of which are secured to hooks or releasing
devices h, h¹, in combination with a third or operating rope or cord g, passing
over a pulley such as b¹ suitably arranged for the purpose, the whole combined and
operating substantially as herein described and shown with reference to Fig. 2 of
the accompanying drawings.
