Improved Appliances for Disengaging Boats.
WILLIAM CRANG, 8 Brassey Square Shaftsbury Park, London, Messenger, and
GEORGE HARRIS, 34 Selcroft Street East Greenwich, Messenger, 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 :-
The object of our invention is to effect improvements in appliances for dis-
engaging boats.
Our invention consists of an improved form and arrangement of disengaging
hooks. One of these hooks is attached to the slings at the bow of the boat &
another to those at the stern, whereby the boat is slung to the davits, ready for
lowering; the disengagement of the boat from the falls being effected by one man
in the boat, on or before its reaching the water.
And in order that our said invention may be particularly described & ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of our improved disengaging appliance, after being released
from the falls, and Fig. 2 is a section showing its position, when the boat is slung
to the davits.
A is the shell of the appliance. B is the hook, pivoted to the shell at g. C is a
catch, pivoted at h. D is a safety pin. EE are the shackles, attached to the
slings k k.
m is the eye of the pulley attached to the fall, shown by dotted lines
in Fig. 2.
In order to sling the boat, the hook B is passed through the eye m attached to
the fall. The safety pin D. is then placed in the holes d' of the shell whereby the
hook B is secured in position. The appliance is then ready for hoisting.
When about to lower the boat the pennants Fare hauled taut by means of
purchase falls the end being made fast to a cleat in the stern.
The safety pins D are then removed, and the boat is lowered by the falls, the
pennant F holding the catch C in position. When the boat rests on the water the
purchase falls are released. This slackens the pennants F, at each end of the boat,
and releases the catches C. The end of the hook B then throws back the catch C,
and releases the boat from the falls; both ends of the boat being thereby
simultaneously released.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. An appliance for disengaging boats consisting of a shell A. or its equivalent
fitted with shackles E. E., a pivoted hook B, and pivoted locking catch C; the
catch C being capable of being locked by the safety pin D or the pennant F, the
pennant forming a purchase to the tail end of the catch C for locking the hook B;
all severally operating substantially as herein before described and illustrated by
the drawings.
2. The general construction, arrangement and combination of the several and
respective parts, together forming our invention of an appliance for disengaging
boats, substantially as herein before described and illustrated by the drawings.
