I, WILLIAM HORSEMAN Pattern inaker 37 Plevna Street West. Hartlepool County
Durham, do hereby declare the nature of this invention to be as follows:-
An apparatus by which a ship's boat may be instantaneously lowered from the deck
of a vessel into the water, or lifted from the water to the deck, only one man is
required to do this. The advantages of this invention are simplicity arising from tho
absence of blocks, shackles, loose fall-ropes & the easy method of unfastening the boat
prior to lowering.
Guys, hinged or loose chocks, boat beams, lanyards for lashing boat to deck are all
done away with & in place of the ordinary cumbrous chock-stands & stays, the boat
stands are combined with the davits & move with them on one centre.
The davits being the width of the boat inboard are not in danger of being damaged
by contact with coal spouts &e when the vessel is in dock.
It will be impossible for the boat to be lowered except on an even keel as both falls
pay off the same barrel together & cannot foul.
In place of the ordinary manilla rope used for the boat fall-ropes, flexible steel wire
rope of a small size is substituted, of this about th of the ordinary amount will be
required. The brass bushed metal sheaves which will be used will not be so liable to
corode & foul as are the ordinary wood blocks & sheaves. It will be impossible for
the wire rope in any manner to get out of gear.
The passage to the ships side between the davits will not be blocked by the stays
the boat stands as is the case in the ordinary way.
of
The great feature of this invention is that one man by merely turning the handle of
the barrel once throws the weight of the boat on to the davits, this causes the davits
with the boat to fall out over side of ship as shewn in plan. The boat can be held in
this position or lowered at the discretion of the person in charge of the landle.
The boat is kept in position by the two chains as per plan. To release these all that
is necessary is to turn the two hooks.

page_text: 1, WILLIAM HORSEMAN, Pattern Maker, residing at 37 Plevna Street, West,
Hartlepool, County Durham, England 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-
A Combined Lifting and Boat Lowering Apparatus, by which a Boat of any
description can be lowered from a ship's or vessels deck into the water, by one man,
either from the deck of Ship or vessel or from the Boat, when in the boat, by
releasing or keeping the rope in hook at the bottom of Boat, one man can lift the
boat out of the water, and replace it on chocks..
The advantages of this invention are simplicity arising from the abscence of blocks,
shackles loose fall ropes, and the easy method of unfasting the boat prior to lowering,
guys, hinged or loose chocks, Boat beams, Lanyard's for Lashing boat to deck, are all
done away with, and in place of the ordinary embrous chocks, stands and stays the
Boat stands and davits are combined and move on a Centre pin or bolt that passes
through the combined boat stands and davits into and fastened in the davit stands.
The davits being the width of the boat inboard, are not in danger of being damaged
by contact with coal spouts &c. when the ship or vessel is in dock.
.
It will be impossible for the boat to be lowered, except on an even keel, as both
falls pay off the same barrol together, and cannot foul, as the screw or worm wheel
is between the two groves that receive the steel wire or chain fall ropes.
In place of the ordinary manilla rope used for the boat fall ropes, flexible steel wire
rope or chain of a small size, is substituted of this about one fifth of the ordinary
quantity will be required.
The brass bushed metal sheaves which will be used will not be so liable to corode
and foul as are the ordinary wood sheaves.
It will be impossible for the wire rope or chain in any manner to get out of gear.
The passage to the ships side between the davits and stands will not be blocked by
the stays of the boat stands, as in the case in the ordinary way.
The great feature of this invention is that, one man can release the boat, and have
it down ready for as many person's to get into the boat as wish to leave the vessel.
The Officer that takes charge of the boat can lower the boat (wherein is as many
person's as the boat can carry) either by the brake handle on deck, or, by the rope
that communicates with the brake handles and the boat, the Officer can lower away,
quick, or slow and stop and start again at discretion as soon as the boat is water borne,
the hooks detach themselves when the boat is quite free from the ship or vessel..
The apparatus is constructed, and numbered on drawings, in the following manner,
The Davit stands 1, 1, are constructed of angle iron, or steel, with a foot, or base,
turned, & welded, & strengthened with a plate of iron, 9, 9, commonly called a knee,
securely riveted to the perpendicular. The guide bars and stays, 2, 2, are constructed
of bar iron, or steel, with pieces of cast iron at the top with a groove in them, to allow
the boat falls to pass clear through them, and bolt holes to bolt the guide bars 2, 2,

page_text: together at top, at the base or floor the guide bars 2, 2. are bolted to cast iron shoes,"
socurely fastened to floor or deck, the stays 2. 2. are made of the same material as
guide bars, and can either be riveted with straps or welded to guide bars at junction.
The outside stays have a foot turned on them to bolt down with, the inside stays are
riveted to knees 9. 9.
At the junction of guide bars and stays 2. 2. the bolt or pin goes through on which
the combined davits and boat stands H, H, move. The cam levers A, A, work in top
of perpendiculars 1, 1, on the inside flange of which there are oblong holes through
which the toggles on the cam levers A, A, pass through & fasten the combined davits
& stands H, H.
The stays 3, 3, and 4 are for staying davit stands fore & aft.
The combined davits and boat stands H. H. are .constructed in the following
manner,
The davits are constructed either of bar iron or steel riveted together with pieces of
iron between, or of channel iron, or steel, (of this section
) the outside bars
of boat stands are riveted to davits near the bottom, and extend the length required
with pieces of iron riveted between the outer ends, on which are fastened eyes, to
receive the ends of chains or grips B, B.
The inside bars are riveted to & between the davits and extend down to outside bars
at the point where the bolt or pin passes through on which the combined davits and
boat stands move.
The chocks G. G. are made of wood and riveted to the outside and inside bars.
The urs 7 & 8 tie the fore & aft davits together and prevents oscillation when the
davits are over the ships or vessels side.
The five cast iron brass bushed sheaves are so arranged that they cannot foul or the
boat fall ropes jump off, as they are enclosed within the sides of the combined davits,
and boat stands and move with them.
There are also two sheaves to each davit stand and two to the winch, to guide the
boat falls on to the barrel of winch.
The winch is constructed in the following manner, The winch stands, 10, are made
of cast iron, on the end next to handle C there is an oblong hole, or slot, 11 for screw
or worm shaft M, to rise or fall, when worked with brake lever F.
The barrel of winch is also cast iron with a groove on each side for boat falls to
wind on and off; and in the space between the two grooves the screw, or worm wheel,
with a bevelled flange on each side receives the brake K. which is made of thin bar
iron or steel with the ends turned to form a bolt hole through which (a
goes and is bolted over the screw or worm shaft M. with two keeps.
bolt)
The brake K has a piece of wood fastened to it to ensure more friction when
lowering.
The brake lever F works between two lugs cast on winch stand, 10, and extend the
required length with a handle on the top and an eye for the rope J. to fasten to, and
about midway a lug is forged on from which another lever 12 works up to the worm
or screw shaft M and embraces loosely so that when the shaft is raised up out of gear
with wheel it will not jamb, and the pall fixed at bottom of lever F drops into recess
and prevents the worm or screw being connected with wheel.
The attaching eyes and detaching hooks D, D), are made of wrought iron with a
square hoop through which the boat falls pass on to. & faster with a thimble in a slot
in the lower part near the hook and work on a pin or bolt and the eyes at the top.
being heavier than the hooks at the bottom when the weight is released the eyes fall
over & detach the hooks.
To unfasten or release the boat the person turns the two cam levers A, A, (Fig. I.
II. III.) which unlock the, combined davits & boat stands H, H, & G, G, at the same
time releases the chains B. B, which fasten the boat in the chocks G. G. then take a
few turns with the winch handle C. untill the attaching eyes D, D, will rest on the

page_text: top of davits at E, E, then reverse the turning of the winch handle C. and the weight
of the boat brings the combined davits & boat stands H, H, & G, G, in the position
shown in (Fig. IV, V, VI,) level with the vessel's or ships deck, As many persons
as wish to enter the boat can do so when the officer or person in charge takes the
chain I, off brake handle F and by either pressing the brake handle F when on deck
or pulling the rope J (which rope is fastened to brake lever and leads through an
eye fast on winch to the hook in the bottom of the boat) when in the boat lifts up the
screw shaft M, M, out of gear and applies the brake K at the same time then the
person who has charge can either lower away quick, slow, or stop & start again as
desired, the brake lever F is provided with a loose pall that drops into notch so that
there is no danger of the screw dropping into gear with the wheel when the person
leaves loose of brake handle F, or rope J, which allows the boats to run down until
water borne when the attaching eyes D, D, fall over and release the hooks, when the
boat is quite, free from the vessel or ship.
To lift or raise boat out of the water attach the eyes D, D, on to the hooks in the
boat, drop the screw shaft M, M., into gear with wheel then fasten chain I on to the
brake handle F and commence turning winch handle C, until the shackles or stops on
the eyes D, D, come against the davits at E, E, when the boat can either he left
hanging out over ship's or vessels side or by continuing the turning of the winch
handle it brings or raises the davits & chocks H, H, & &G with the boat from the
position shewn (in Fig. IV, V, & VI,) to the position as shewn (in Fig. I, I, III,)
when by reversing the turning of the winch handle C it lowers the boat on to the
chocks G. G. then pass the chains or grips B, B, over the boat and slip the eyes or end
links on to the cam levers A, A, which pulls down the chains or Grips B, B, tight and
locks the davits at the same time, so that the boat with the combined davits are
securely fastened.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed I declare that what I claim is,
1st. Combined Davits and Boat stands that work on onc centre pin or bolt at
cach end.
2nd. The two Cam Levers for locking davits and fastening boat at the same time.
3rd. By using for boat falls, Steel wire rope or chain and dispensing with all
Blocks.
4th. The barrel of winch having screw or worm wheel with a groove on each side
for the steel wire rope or chain boat falls to wind on and off.
5th. The brake being connected to and with loose screw shaft descends from the
screw shaft down to and underneath the harrel and ascends at the other side up to the
other end of same shaft, so that when the screw shaft is lifted out of gear it applies
the brake at the same time.
6th. The attaching eyes which bring the combined davits and stands over the ships
side and are to be hooked on to the hooks in boat, to lift the Boat out of water &
replace it on the chocks.
7th. The whole of this apparatus to be used for or in any other capacity other than
for lifting and lowering ships boats.
8th. Brass bushed metal sheaves that work in the combined davits & stands.
9th. Arrangement of sheaves for lifting and lowering combined Davits & boat
stands either with or without the boat.
