Submarine and Torpedo Boat for Use in Naval Warfare and Diving
Operations.
We, SILAS ROGERS and GEORGE ROGERS, both of 41 Port Hall Street, Dyke
Road Drive, Brighton, Sussex, Carpenters, 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 :-
The boat is made in cylindrical form capable of being expanded or contracted
by means of a screw or screws or levers worked by hand or other motive power
which causes it to rise or sink in the water. At the stern is a propellor or
propellors worked by electric or other motors. At a convenient part of the boat
is a chamber with water-tight doors to allow of egress or ingress when under water.
On the upper part or deck is a conning tower or towers fitted with water-tight
doors. Rudders are placed at the stern and other parts of the boat. The water-
tight doors are hung in sockets with the rebates fitted with rubber flanges. A
cross bar on the centre of the door drops into a slot on each side and is screwed up
with a nut and balt or secured with a lever. There are two rudders, one on each
side of the boat, to steer the latter in an upward or downward course; the stern

page_text: rudder is used in the usual manner. Torpedoes are launched from the deck or
from tubes fitted with watertight doors and slides.
Our invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a plan of our improved, boat.
Fig. 2 is a vertical longitudinal section drawn on the line 2-2 of Fig. 3.
Fig. 3 is a longitudinal horizontal sectional view.
Fig. 4 is a vertical cross section drawn on the line 4-4 of Fig. 2.
Fig. 5 is a vertical cross section drawn on the line 5-5 of Fig. 2.
Fig. 6 is a horizontal section of part of the bow of the boat showing a tube for
discharging torpedoes.
Fig. 7 is an elevation and Fig. 8. is a cross section of a water-tight door.
Figs. 6, 7, 8 are drawn to larger scales than Figs. 1 to 5.
The body of the boat is constructed of two parts a a¹ telescopically fitted so that
the part a' can slide to and fro within the part a. The part a is provided with a
packing or gland at a to fit tightly around the part a', and this latter part is fitted
with a packing or gland at a³ to fit tightly within the part a to prevent the
entrance of water into the interior of the boat between the parts a a¹ thereof.
The packing of the glands may be somewhat similar to a pneumatic tyre. In
order to obtain still further security against the entry of water into the
interior of the boat through any leakage past the glands a' a', we fix around
the inner end of the part a¹ one edge of a piece of waterproof canvas or other
suitable material b, the other edge of which is fixed to the interior. of the
part a. In order to ease the motion of the parts a a¹ and guide them in
relation to each other we fit around the exterior of the part a' two or more
series of rollers or wheels c which bear against and run on rails (not shown)
on the interior of the part a. The part a is. formed with a hollow, keel d
within which works a guide bar e fixed to the part a'. Thus the parts a a¹
will be kept in correct line with each other by means of the guide bar e,
which, in other words, will prevent any rotary motion of the parts a a¹ in
relation to each other. Motion is given to the part a' to expand or contract
the boat in length by means of a screw working within a nut g formed or
fixed in a frame a fixed to the inner end of the part a' and supported in a
bearing formed or fixed in a frame a fixed within the part a. Thus, by
turning in one or the other direction the hand wheel fixed on the screw f, the
latter will move the part a¹ to expand or contract the boat in length as may be
desired.
i i are side rudders or planes which are employed to steer the boat in either an
upward or downward course as may be desired. These rudders or planes i i are
fixed on the ends of a cross shaft which can be rotated in the required direction
by means of a tiller wheel and chain, which latter passes around a suitable
chain wheel on the tiller wheel shaft or axis and another on the cross shaft i¹.
jis the stern rudder, the tiller arm of which is connected to the two ends of a
chain k which is guided by suitable guide rollers and passes around a chain wheel m¹
fixed ou the shaft of the tiller wheel m. A pair of guide rollers are carried by a
bracket fixed to the part a' to keep the chain k taut at all relative positions of
the parts a a¹
.J
n is a chamber for affording ingress and egress to the boat; this chamber is fitted
with water-tight doors n', which may be constructed, as shown at Figs. 7 and 8,
with a rebate to fit a corresponding rebate in the walls of said chamber n, suitable
packing being employed between.such parts to secure a tight joint. The said doors
are fitted with cross bars n³ mounted on screw bolts n', on which latter are mounted
internally threaded clamping wheels n'. These cross bars n³ can be swung on their
centres into and out of position with the sockets n' to secure or release the door by
the aid of the wheels n. A valve enables the chamber n to be filled with water
when a man desires to enter said chamber from the outside or after a man has
⚫ entered such chamber from the inside of the boat. When entering the boat the
chamber n is first filled with water by the valve n', the door n is then opened,

page_text: the man enters and then closes such door n' securely behind him; the water is
then removed in any suitable manner from the chamber n, after which the
door n is opened; the man then enters the interior of the boat and closes the
door n securely; for leaving the boat the door n' will be first opened, no
water being in the chamber n, a man will enter said chamber and the door n'
will be hermetically closed; the chamber n will then be filled with water, the
door n will then be opened, the man will walk out of said chamber and
securely close the door n', after which the water can be forced out of said
chamber. The chamber n communicates with the conning tower a and the latter
with the lower parts of the boat by the stairs a².
o, Fig. 6, is a torpedo tube fitted in the bow of the boat and communicating with
the interior of the latter by a door o¹ of somewhat similar character to the doors n¹ n².
o is a sliding door at the fore end of the tube o which is employed to open or close
the fore end of such tube. For charging the tube o with a torpedo and permitting
its exit therefrom, the doors o' o' are opened and closed similarly to the doors n'
and the chambero is filled with water and emptied in like manner to the chamber n.
pp are propellors which may be worked by electric or other motors.
n'
The boat will be provided with stores of compressed air or oxygen to be used as
required and as is well understood.
The details of construction of the various parts may be varied without departing
from the peculiar character of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
