We, HAVELOCK HARFORD, Engineer, of 6 Victoria Terrace, and CHARLES
FREDERICK SUTOLIFFE, Surgeon Dentist, of 5 Ocean Road, both of South Shields,
in the County of Durham, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to an improved mode of constructing torpedo launches, small
gunboats and similar craft in such a manner that they are capable of being readily
taken into separate parts when required, for conveyance overland for use in inland
lakes or rivers or for transport-by sea.
The vessel consists of three main parts viz: a deck of ✓ section containing the
boilers, engines and machinery etcetera, traversed by. two fore and aft girders, one
along each side, and two hollow cylindrical vessels tapering from centre toward each
end. These vessels are air tight, and may be fitted with air tight compartments, and
are situated one on each side below the deck portion to which they are attached by
stanchions bolted each end of each of the fore and aft girders by means of strong
bolts through the stanchions the lower ends of which form bearings in which the
"trunnion" ends of the tapered vessels work. These vessels form the buoyant portion
being nearly entirely submerged and also form the propellers being provided with
right and left hand blades either in continuous spirals or at intervals along their
length, except at centre where they are each fitted with a pitched chain wheel
to receive a pitched chain from a driving wheel on main shaft of engine, an opening
being left in the deck portion for the passage of the two chains to the propellers
which are driven one right and the other left hand.
The engines will be preferably high pressure and connected direct to the driving
shaft overhead but may be geared if necessary to get up the revolutions of propellers.
The deck portion is fitted to suit torpedo service, to carry a gun or as may be required.
The vessel has no rudder, steering and manoeuvring being effected by working the
propellers separately or one ahead the other astern.
When required to be taken apart for land or other transport the deck with girders
and stanchions forms one piece or the stanchions may also be detached-and each
of the tapered vessels or propellers form separate pieces but in larger craft still further
separation is easily provided for.

Improved Torpedo Launches, Small Gun Boats, or similar Craft.
We, HAVELOCK HARFORD Engineer of 6 Victoria Terrace and CHARLES FREDERICK
SUTCLIFFE, Surgeon Dentist of 5 Ocean Road South Shields in the County of Durham
do hereby declare the nature of our invention for IMPROVEMENTS IN TORPEDO
LAUNCHES, &c., 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 an improved mode of construction torpedo launches, small
gun boats and similar craft in such a manner that they are capable of being readily
taken into separate parts when required for conveyance over land for use on inland
lakes or rivers or for transport by sea.
The vessel consists of three main parts, viz, a deck of V section containing the 1
boilers engines and machinery etcetera, traversed by two fore and aft girders one along
each side, and two hollow cylindrical vessels tapering from centre towards each end.
These vessels are air tight, and may be fitted with air tight compartments and are
situated one on each side below the deck portion to which they are attached by
stanchions bolted to each end of each of the fore and aft girders by means of strong
bolts through the stanchions, the lower ends of which form bearings in which the
trunion ends of the tapered vessels work. These vessels form the buoyant portion
being nearly entirely submerged and also form the propellers, being provided with
right and left hand blades either in continuous spirals or at intervals along their
length except at centre, where they are each fitted with a pitched chain wheel to
receive a pitched chain from a driving wheel on main shaft of engine an opening
being left in the deck portion for the passage of the two chains to the propellers which
are driven one left hand the other right hand. The engines will be preferably high
pressure and connected direct to the driving shaft over head but may be geared if
necessary to get up the revolutions of propellers. The deck portion is fitted to suit
torpedo service, to carry a gun or as may be required. The vessel has no rudder
steering and manucevering being effected by working the propellers separately or one
ahead the other astern.
When required to be taken apart for land or other transport, the deck with girders
and stanchions forms one piece, or the stanchions may also be detached, and each of
the tapered vessels or propellers form separate pieces, but in larger craft still further
separation is easily provided for.
DESCRIPTION OF DRAWING.
The accompanying drawings illustrates our invention. Fig. 1 on drawing No. 1 is
LLU 11

page_text: exception that the blade is right hand, and these are driven by chain wheels shewn on
end elevation drawing No. 2 figs. 12 & 13.
Fig. 8 on drawing No. 1 represents chain wheel on each body, fig. 10 on drawing
No. 1 and figs. 10 and 11 on No. 2 are girders with stanchions figs. 3 and 4 on No. 1
drawing bolted to the ends.
Fig. 5 on No. 1 shows bolt head which forms bearings for trunion ends, these bolts
are square and run right through stanchions and girder ends and fastened on top with
a nut fig. 15 on No. 1.
Fig. 14 on No. 1 represents V shaped deck, fig. 7 on No. 2 drawing shows
horizontal boiler.
Fig. 6 on No. 2 are engine side frames which are bolted on both girders, Figs. 16
and 17 on No. 1 and No. 2 drawings represent oscillating cylinders which drive chain
wheels figs. 12 and 13 on No. 2 drawing.
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
That the buoyant portion of the vessel being also the propelling portion it does
away with low resistance and suction at the stern.
