PROVISIONAL SPECIFICATION.
Improvements in Stowing Boats and Rafts upon Skids.
I, RICHARD ROPER, of Palace Chambers, 9 Bridge Street, Westminster, in
the County of Middlesex, Marine Contractor and Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to Improvements in Stowing Boats and Rafts upon
Skids.
For stowing boats and rafts upon skids I provide two chocks. One of these
lies at each end of the boat or raft and is hinged to the side of the skid in such a
manner that the pin upon which it turns is made to turn upon its axis with the
movements of the chock, being of course supported in suitable eyes secured to the
skid. Each end of this pin is grooved longitudinally so as to receive a short pin
or tumbler pivoted to the side of the skid at each end of the slotted pin. When
the said tumblers lie in these grooves their axes are in a line with that of the
grooved pin. Suitable means are provided for turning the chocks downward out
of engagement with the boat. The boat is held down upon the chocks by means
of cords connected to clips or hooks passed over the gunwale of the boat and
provided with eyes or loops at their lower end threaded upon the tumblers pivoted
to the skids. As will be seen from the foregoing description these tumblers are
held in position by the grooved end of the pin upon which the chocks turn.
the chocks being turned down to release the boat the pin upon which it turns is
rotated so as to bring the grooves in its ends into such a position as to liberate the
tumblers which either fall away or may be turned to release the cords holding
down the boat.
On
When the boat or raft is stowed on the skids at some distance inwards from the
davits I mount it upon a cradle or trolley provided with anti-friction wheels so that
on the release of the chocks and holding lines in the manner already described the
boat or raft may be pushed towards the side of the vessel so as to be lifted by the
davits.

COMPLETE SPECIFICATION.
Improvements in Stowing Boats and Rafts upon Skids.
I, RICHARD ROPER, of Palace Chambers, 9 Bridge Street, Westminster, in
the County of Middlesex, Marine Contractor and Engineer, 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 :-
This invention relates to Improvements in Stowing Boats and Rafts upon
Skids.
For stowing boats and rafts upon skids I provide two chocks. One of these

manner that the pin upon which it turns is made to turn upon its axis with the
movements of the chock, being of course supported in suitable eyes secured to the
skid. Each end of this pin is grooved longitudinally so as to receive a short pin
or tumbler pivoted to the side of the skid at each end of the slotted pin. When
the said tumblers lie in these grooves their axes are in a line with that of the
grooved pin. Suitable means are provided for turning the chocks downward out
of engagement with the boat. The boat is held down upon the chocks by means
of cords connected to clips or hooks passed over the gunwale of the boat and
provided with eyes or loops at their lower end threaded upon the tumblers pivoted
to the skids. As will be seen from the foregoing description these tumblers are
held in position by the grooved end of the pin upon which the chocks turn. On
the chocks being turned down to release the boat, the pin upon which it turns is
rotated so as to bring the grooves in its ends into such a position as to liberate the
tumblers which either fall away or may be turned to release the cords or chains
holding down the boat.
When the boat or raft is stowed on the skids at some distance inwards from the
davits I mount it upon a cradle or trolley provided with anti-friction wheels so
that on the release of the chocks and holding lines in the manner already described,
the boat or raft may be pushed towards the side of the vessel so as to be lifted by
the davits.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompanying
drawings, of which Fig. 1 is a part side elevation; and Fig. 2 an end elevation
of a boat and skid shewing the application of my invention; Fig. 3 section
on line A-B (Fig. 2) and Figs. 4, 5 and 6 a side elevation plan and end elevation
respectively of the boat trolley.
The boat or raft a rests on the skids b of which two or more may be provided,
and is supported thereon at each end by chocks c hinged to the sides of the skids in
such a manner that the pins d upon which they turn and which are supported in
suitable eyes e are made to revolve upon their axes with the movement of the
chocks.
Each end of each of these pins d is grooved longitudinally preferably in the
manner shewn in Fig. 3 so as to receive the free end of a short pin or tumbler f
pivoted to the skid.
These tumblers have threaded on them eyes or loops on the ends of chains or
cords g which chains or cords pass under the skids and are secured by clip hooks h
to the gunwale of the boat or to the raft, so holding the latter down upon the
skids.
It will then be seen that when the chocks c are turned down and the pin d
thereby revolved, the tumblers will be allowed to fall and consequently the end of
the chains or cords g released.
Cords may be connected to the upper ends of the chocks c or other means
provided to enable them to be pulled down out of engagement with the
boat.
When the boat is stowed on the skids at some distance from the davits, I mount
it upon a cradle or trolley k shaped on its upper surface to the lines of the boat
and provided with anti-friction wheels and guides m to enable it to run on the
skids to allow said boat when released to be pushed along the skids towards the
davits.
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. The apparatus for supporting and holding boats and rafts upon skids,

page_text: 2. The combination of the apparatus above claimed with trolley k, sub-
stantially as and for the purpose described and illustrated in the accompanying
drawings.
