Complete Specification Left, 2nd Nov., 1898-Accepted, 23rd Dec., 1898
I, HARRY EDWARD MORRISS, of 31, Moray Road, Finsbury Park, in the County
of London, Engineer, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to a portable and adjustable steam motor and apparatus
for driving river or other boats.
A water tight chamber containing the engines is fixed to the outside of the stern
of boat by means of adjustable clamps or other adjustable fixings, so that the
apparatus can be attached or detached without alteration or injury to the boat.
The watertight chamber containing the engines, and to which the propeller is
attached on the outside thereof, by means of a shaft passing through a stuffing
box and connected to the engines; is wholly or partley submerged in the water.
The inlet and outlet pipes for the supply and exhaust of steam, to and from
engines are fixed to the water tight chamber and connected with the pipes from
the boiler in the boat by means of flexible pipes and unions.

A Portable Steam Driving Apparatus for Boats.
I, HARRY EDWARD MORRISS, of 31, Moray Road, Finsbury Park, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement: -
This invention relates to a portable steam driving apparatus for boats.
A watertight chamber containing the engines is fixed to the outside of the stern.
of the boat by means of adjustable clamps or other adjustable fixings, so that
the apparatus can be attached or detached without alteration or injury to the boat..
The watertight chamber containing the engines and to which the propeller is
attached on the outside thereof by means of a shaft passing through a stuffing box
and connected to the engines, is wholly or partly submerged in the water.
The inlet and outlet pipes for the supply and exhaust of steam to and from
engines are fixed to the watertight chamber and connected with the pipes from the
boiler in the boat by means of flexible pipes and unions.
I now proceed to describe my invention with reference to the accompanying
drawings.

adjusting chamber A to the sloping stern of a boat.

The same letters denote the same parts in all figs.
Fig. 1 is a section showing position of tubes U U for the inlet and outlet of
steam and tube S forms a bearing for the spindle R.
A is watertight chamber containing pipes U, U for supplying and letting off
exhaust steam too & from cylinders B, B.
:
C is crank shaft D is shaft to which propeller E is attached.
Fis ball thrust bearing G is stuffing box 0 is rudder attached to spindle R
which passes through tube S and is worked by yoke T.
I is a flat bar having holes drilled at varying distances to enable chamber A
to be raised or lowered to suit the draught of the boat to which it is attached J J
are two movable clamps attached to bar I by means of bolts & nuts.
H is a movable joint to allow chamber A to be fixed in a vertical position
irrispective of the extent of slope on the stern of boat.
The chamber A is attached to the stern of the boat by passing rod K through
holes in the ends of clamps J J and into rudder eyelets L L, usually found on the
stern of a boat.
The chamber A is kept rigid by screwing the rods M M out of the luggs V V
into the sockets shown at the ends of bar N, they force the chamber A outwards
thereby causing same to be a fixture enabeling the rudder to be operated on
by yoke T.
The object of these moveable clamps, as before stated, is to keep the watertight
chamber in a vertical position on the stern of any boat, whatever its slope may be.
In reference to the whole of the drawings, I say that the apparatus is shewn
thereby irrespective of the letters, and these explanations, in a manner sufficient
to enable any competent workman to make the same.
Besides being fixed to a boat by the devices shewn, the apparatus can be fixed
to sailing vessels and other craft by other means.
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
1. In relation to an apparatus worked by steam power for propelling a rowing
or sailing boat or the like, a watertight chamber containing an engine or engines,
separate from the boat or vessel, and to be used wholly or partly submerged in
the water, substantially as described.
2. An apparatus worked by steam power for propelling boats or other vessels,
substantially as described, capable of adjustment to any rowing or sailing boat.
3. In connection with an apparatus worked by steam power for propelling a
rowing or sailing boat, the encasement of steam engines in a chamber of sufficient
buoyancy to sustain them in the water, in combination with a propeller.
