PROVISIONAL SPECIFICATION.
An Improved Combined "Chock" and "Gripe" Arrangement for
.Ships' Boats.
WILLIAM BELL Manager Messrs. Gourlay Brothers & Co. Dundee do hereby
leclare the nature of this invention to be as follows:-
"
The boat is supported on struts, movable vertically through the "skids." To
these struts the "chocks are attached. Instead of the ordinary "gripes" flat iron
or steel bars are substituted passing through slots in the "skids," hooked over the
gunwale and secured in position by stops on the underside of the "skids." The
whole is so arranged that by moving a lever the "gripes" are released, and
the struts and chocks fall down clear, leaving the boat completely free, suspended
from the davits, ready for swinging out and lowering, without touching the falls.
Dated this the 18th day of December 1891.
COMPLETE SPECIFICATION.
An Improved Combined "Chock" and " Gripe" Arrangement for
Ships' Boats.
I WILLIAM BELL of Camperdown Shipyard Dundee in the County of Forfar
North Britain, Naval Architect, 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 boat is supported on struts movable vertically through the skids. To these
structs the chocks are attached. Instead of the ordinary gripes flat iron or steel
bars are substituted passing through slots in the skids hooked over the gunwale and
secured in position by stops or by preference secured to hook bolts fastened to
the skids.
On the accompanying sheets of explanatory drawings
Figure 1 Sheet 1 is a transverse vertical section at an end strut and
Figure 2 Sheet 1 a transverse vertical section through middle strut.
Figure 1 Sheet 2 shews catch lever in place and boat stowed.
Figure 2 Sheet 2 shews catch lever raised and supporting arm released.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In carrying out my invention when the boat has to be stowed the struts A
working in the sockets B are supported by portable pins (not shown) passing
through holes C in the struts A. The boat is then lowered by the tackles until
it rests in the chocks D. The gripes E are now inserted in the hook bolts F fixed
to the skids G and the lever H is raised revolving the shaft I and with it the
tongues K forged on the shaft I at each socket B. These tongues K work into slots
cut in the struts A and thus raise the boat sufficiently to tighten up and secure the
gripes E. When the gripes E are tight the catch lever L engages the arm M
keyed on the shaft. I and securely holds the boat in position. The portable pins in
the holes C of the struts A are now withdrawn and the boat is stowed.
When the boat has to be got out the catch lever L is raised when the struts A
and with them the chocks D at once fall down clear of the boat the gripes E
release themselves and the boat hangs suspended by the tackles from the davits
ready for swinging outboard.

page_text: Having now particularly described the nature of my said invention and in what
manner the same is to be performed 1 declare that what I claim is
The improved combination of parts herein before described and shewn in the
accompanying drawings whereby a boat is stowed and secured on shipboard in such
manner that it can be instantaneously released from all its fastenings and got ready
for swinging outboard by a single movement of a lever.
Dated this Sixteenth day of September 1891.
