manner,
My invention is intended to clear the boat from the ship in a prompt and safe
to avoid the swamping of the boat; it is absolutely under the control of
one man by lifting the lever upwards to release the boat from her tackles simul-
taneously fore and aft.
My invention consists of a shackle of a special type fixed to the lower block of
the tackle, and of an apparatus adapted to the life or other boat. The said
apparatus is composed,
1st. Of an iron shaft, of which the strength and dimensions vary with the length
and weight of the boat to which it is to be adapted. At each end of the said shaft
there is a cup in which a groove is cut, and in the centre of the shaft a working
lever is pinned on it.
Both cups are of corresponding shape and dimensions, while the longitudinal axis
of one groove corresponds to the axis of the working lever and also to that of the
groove in the second cup.
2nd. Of two forged iron chairs consisting of two uprights, intended, one to support
the cup of the shaft, and the other to maintain the hinged bolt ;-One of these
chairs is placed at each end of the boat in a suitable manner and secured to the
boat, once the cups of the shaft have been introduced in their bearings, at the top of
which, we may mention here, an oil hole is drilled.
Now, it has already been understood that the hinged bolt can be lowered and
lifted at will, and that when it is lowered in the axis of the groove cut in the cup
of the shaft, its end easily penetrates into the interior of the cup and that at this
moment if the shaft is turned with the working lever, the end of the hinged bolt is
locked in the cup.
Then, taking a boat suspended by means of my apparatus, which can be done by
introducing the hinged bolt into the shackles fixed to the tackles, and bringing
them (the hinged bolt) down in the axis of the grooves cut in the cups, forcing them
into the interior, and making them fast by turning the shaft from right to left, or
left to right, which is immaterial, it is easy to understand that it is only necessary,
by bringing the working lever in a vertical position with the handle upwards, to get
the grooves cut in the cups so placed again, that the hinged bolt will be released,
and consequently at the moment of letting go, the boat will be freed simultaneously
from the fore and aft fastenings.
For the better intelligence of this Specification, I have annexed to it drawings of
the different parts of my apparatus, marked I to 1X as follows

Improvements in Disconnecting Gear for Life and other Boats.
1 ABRAHAM BLAMPIED 12 Faubourg de la Barre, Dieppe, Seine Inferieure
France, Marine Superintendent 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 has for its object to promptly and safely clear a boat from a ship
-so as to avoid accident or injury to the boat. One advantage of my invention is
that it is absolutely under the control of one man who by simply raising a lever
releases the boat from her fore and aft tackles simultaneously.
My invention consists of a suitable shackle fixed to the lower block of each tackle
and of an apparatus whereby to suspend the boat from such tackles. This apparatus
:consists of an iron shaft the strength and dimensions whereof vary with the length
and weight of the boat which it is intended to carry. A working lever is fitted to
the centre of such shaft while at each end of the latter there is a grooved cup.
Both cups are of corresponding shape and dimensions and the longitudinal axis of
the groove in one cup corresponds to the axis of the working lever and also to that
of the groove in the other cup. Placed at each end of the boat is an iron chair
furnished with two uprights one of which carries the cupped end of the shaft while
the other forms a bearing to carry a hinged bolt which can be raised or lowered at
will. The chairs are placed in any convenient position and after the cupped ends of
the shaft have been fitted in their bearings such chairs are screwed or otherwise
fastened to the boat. Suitable oil holes are drilled in the cup bearings to admit of
lubrication when requisite.
The boat is suspended from this apparatus by inserting the hinged bolts into the
shackles fixed to the boat tackles and then bringing such bolts down the grooves
cut in the cups and forcing them into the hollows of the cups wherein they are
locked by operating the working lever on the centre of the shaft and turning such
shaft from right to left or left to right as most convenient. In order to release
such bolts it is only necessary to bring the working lever in a vertical position with
the handle upwards whereby the grooves cut in the cups are brought into such a
position that the bolts are released, and consequently at the moment of letting go,
the boat is freed simultaneously from her fore and aft tackles.
In order that my said invention may be better understood and readily carried
into effect I refer to the drawings of the different parts of my apparatus marked I
.to IX respectively accompanying my Provisional Specification of which drawings
the following is a description-
I. Apparatus shewing the hinged bolts locked in the cups of the shaft.
II. Working lever with the handle downwards.
III. Upright holding the hinged bolt.
IV. Hinged bolt.
V. Section of cup shewing the hollow in the cup together with the groove cut
therein to allow the hinged bolt to pass and be locked in, in the manner herein before
described.
VI. Upright bearing which carries the cup of the shaft.
VII. Hinged bolt shewn through the revolving part of the shackle.
VIII. Shackle with revolving holt fitted themin

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
The improved disconnecting gear for life and other boats consisting of suitable
shackles attached to the fore and aft tackles of a boat and of a revolving shaft fitted
with a working lever and having cupped grooved ends wherein hinged bolts work,
such shaft and bolts being carried in suitable bearings fixed to the boat all sub-
stantially as hereinbefore described and shewn.
