PROVISIONAL SPECIFICATION.
Improvements in and relating to Boats.
We, EUGÈNE MICHEL LÉOMY, of 32, Avenue de Neuilly and BERNARD
CHATEAU, Doctor of Medicine, of 75, Rue St. Dominique, both in Paris, in the
Republic of France, do hereby declare the nature of this invention to be as
follows:-
:-
Our invention relates to a boat provided with means whereby it can be used
as a bridge over a river, canal or the like or several of the boats may be used to
form a bridge, the sections or parts of the bridge resting on intermediate floats.
These boats can be used in time of war for forming bridges and the hold of the
boat can further be utilized so as to serve as a hospital for the wounded.
They can also be utilized as tow-boats for the transport of merchandise, for
dredging purposes, making the foundations of bridges and the like.
The boat comprises two beams or bays located one on each side of the boat in
angular iron frames, these beams or bays being designed to constitute the
bridge.
When the bridge is to be projected the beams are raised by means of pulleys
arranged upon supports or davits carried by the boat. The beams have on one
side at their centre of gravity small pivot-plates.
When the beams have been lifted bars or cross pieces are placed above the
recesses in which they were located and on these bars the beams then rest. By
means of pulleys fixed to the side the beams are turned 90 degrees so as to lie flat
on the deck.
The pivot plates are then fixed to the bars by means of cramps, the davits are
laid along the edges of the vessel and by means of a pulley the two beams are
caused to turn on their pivots in the same direction and at the same time and
are thus brought perpendicular to the axis of the boat.
.
The beams are also provided with pulleys whereby the beams are then moved
longitudinally. The two beams or bays projecting over the sides of the boat are
then brought in a line with each other and the bridge is complete.

Improvements in and relating to Boats.
We, EUGENE MICHEL LÉOMY, of 32, Avenue de Neuilly, and BERNARD
CHATEAU, Doctor of Medicine, of 75, Rue St. Dominique, both in Paris, in the
Republic of France, 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 :-
Our invention relates to a boat provided with means whereby it can be used as a
bridge over a river, canal or the like or several of the boats may be used to form a
bridge, the sections or parts of the bridge resting on intermediate floats.
These boats can be used in time of war for forming bridges and the hold of the
boat can further be utilized so as to serve as a hospital for the wounded.
They can also be utilized as tow-boats for the transport of merchandise, for

In the accompanying drawing.
Figure 1 is a longitudinal elevation of a boat provided with means whereby it
can be converted into a bridge according to my invention.
Figure 2 is a transverse section, and,
Figure 3 is a plan of the same.
Figures 4, 6 and 7 are plans, and,
Figure 5 is a transverse section illustrating the various positions of the parts
when bridging a stream or the like.
The boat comprises two beams or bays T T located one on each side of the boat
in angular iron frames m, n, p, q, these beams or bays being designed to constitute
the bridge.
When the bridge is to be projected the beams T, T are raised by means of
pulleys arranged upon supports or davits B, B, B carried by the boat. The beans
have on one side at their centre of gravity small pivot-plates q', 9:
When the beans T have been lifted as shewn by the dotted lines in Figure 2,
bars or cross pieces r, r, r are placed above the recesses in which they were located
and on these bars the beams then rest. By means of pulleys fixed to the side C,
Figure 4, the beams are turned 90 degrees so as to lie flat on the deck in the
position shewn at T', T" in Figure 5.
The pivot plates q, q', are then fixed to the bars r, r," by means of cramps, the
davits B are laid along the edges of the boat and by means of a pulley the two
beams are caused to turn on their pivots in the same direction and at the same time
and are thus brought into the position shewn at T1, T2, Figure 4, perpendicular to
the axis of the boat.
The beams are also provided with pulleys a, a over which pass ropes b, bas
shewn in Figure 6, whereby the beams are then moved longitudinally into the
position shewn in Figure 7. The two beams or bays projecting over the sides of
the boat are then brought in a line with each other by sliding one of them from
the position shewn by the full lines at Ts to that shewn in dotted lines at T
and the bridge is complete.
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. A boat comprising two lateral beams or bridge-bays which can be raised above
the boat, turned 90°, pivotted on turning plates to bring them to right angles to
the axis of the boat, moved longitudinally, and finally brought end to end in order
to constitute a movable bridge, substantially as hereinbefore described.
2. The improved boat and means whereby it can be used as a bridge, substantially
as herein before described and illustrated in the accompanying drawing..
