COMPLETE SPECIFICATION.
Submarine Boat.
I, JAMES RYAN HAYDON, an Engineer, a resident of No. 13 Goldsmith Court,
Cleveland, Cuyahoga County, Ohio, United States of America, 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 :-
My invention relates to a submarine boat constructed of steel plates or their
equivalent and substantially of the form herein after described. The mechanism in
said boat being such that it may be raised or lowered any distance by the
manipulation of the operator within said boat, air and power being supplied from
a tender above through the medium of suitable conductors as herein after fully
explained.
That the invention may be fully seen and understood by others reference will be
had to the following Specifiation and annexed drawings forming part thereof.
Figure 1 is an elevation of my improved submarine boat.
Figure 2 is an enlarged vertical longitudinal section of the middle portion of the
boat.
Figure 3 is an enlarged, skeleton, vertical, longitudinal section of the rear end.
Figure 4 an enlarged, skeleton, vertical, longitudinal section of the forward end
of said boat.
Figure 5 is a cross section on line a, x, Fig. 2, aud
Figure 6 a cross section on line ¹, ¹, Fig. 2.
Like characters of reference designate like parts in the drawings and
Specification.
My improved submarine boat is constructed of sheets of steel of sufficient
thickness, riveted to the frame work of the boat, which consists of steel bands 1, 1, 1,
Figs. 2, 3, 4, 5 & 6, and the girths 2, Fig. 2.
The ends of the boat both rear and forward are conical in form as shown
Within the middle or
in Fig. 1. The middle portion is in the form of a cylinder.
cylindrical portion of the boat is a second cylinder 3, Figs. 2, 3, 4, 5 & 6. The
inner cylinder 3 as well as the outer (which will herein after be called casing, to
avoid prolixity) do not have the same center, the center of the inner cylinder being
lower than that of the outside casing, thus making more weight in the bottom of
the boat and preventing it from rolling over, which owing to its shape would be the
natural tendency were it not thus avoided.
Within the cylinder 3 are two pistons 4 & 5, Figure 2. The piston 4 has a right
hand female thread therein, while the piston 5 has a left hand female thread therein.
A rod 6, Figs. 2 & 3, with a right hand thread thereon is threaded into the piston 4,
the outer terminal extending out of the rear of the cylinder 3, and a rod 7,
Figs. 2 & 4, with a left hand thread thereon, is threaded into the piston 5, the outer
terminal having its bearing at the forward end of the cylinder 3, as shown in Fig. 4.
These two screw rods are rigidly bolted together at their point of contact in the
middle of the cylinder 3 (shown at 8, Fig. 2).
There is a passage way 9, Fig. 2, from the exterior of the boat to the interior of
the cylinder 3. The pistons 4 & 5 are made tight within the cylinder by means of
rubber packing 10, held in close contact by the set screws 11 in the plate 12, said
plate being rigidly attached to the piston.
The rear terminal of the screw rod 6 has a gear wheel 13, Fig. 3, keyed thereon.
The gear 13 is in mesh with the pinion 14 on the shaft 15, on the opposite end of
which is the pinion 16. The pinion 16 is in mesh with the gear 17 on the power
shaft 18, which is connected with the motor. The double screw rod 6 & 7 is
operated by this gear mechanism. It will readily be seen from Fig. 2, that if the

page_text: screw rod is turned to the right it will cause the two pistons 4 & 5 to recede from
the middle of the cylinder 3, thereby permitting a volume of water to enter the
opening 9, equal to the space between the two pistons 4 & 5, which causes the boat
to sink when a sufficient amount of water has been admitted. If the screw rod be
turned to the left, the pistons 4 & 5 will approach each other and force the water
out of the passage-way 9 and cause the boat to rise.
Air is supplied to the boat through a tube 19, Figs. 1 & 3, and the electric
current through a wire 20 from a tug or tender above.
The boat is propelled by a screw wheel 21, Figs. 1 & 3, ou the shaft 22, which
is readily connected and disconnected from the motor shaft 18 by means of the
screws 23 & 24, Fig. 3.
There is an arrangment of pipes under the cylinder 3 for compressed air, which
is forced into said pipes through the tube 19 from the tender above. This may be
done by any known means, as the ordinary air compressor or pump and suitable
valves.
Two lookouts 25 & 26, Figs. 1, 3 & 4, are arranged on the boat; these are also
used for the entrance to the boat when above water level. The doors 27 to the
look outs are operated at follows. The rods 28 extend up from the side of the look
out. An arm 29 is attached to the top of the door and has an eye 30 in the end
thereof. The rod 28 passes through the eye 30, so when the door is raised up, the
weight of said door will cause the eye 30 to bind on the rod 28, and consequently
hold the door at any desired height. I do not however wish it understood that I
confine myself to this form of door, as any suitable door that can be made to fit
air tight, can be used.
I place two thick lenses 31 at the rear and forward ends of the boat for the
purpose of throwing out light provided by electricity.
The boat may be guided by any ordinary rudder 32, operated by a chain or
cable running forward to a wheel.
In the forward part of the boat is arranged a chamber 33, Fig. 4, with an air
tight cover. This chamber is for the purpose of allowing a person sufficiently
protected with any kind of diving clothes or apparatus, to get out of the boat when
under water. The diver enters the chamber 33 and the cover 34 is secured down
air tight, he then opens the lower door 35 and is able to get out. The water enters
the chamber but does not enter the body of the boat owing to the air tight cover 34.
The chamber 33 is also intended to be used in case of any break or accident to the
machinery when under water.
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―
1st. In a submarine boat, a cylinder 3, within an air tight casing with conical
ends, said casing having an opening 9 therein, in open communication with the
middle of the cylinder 3, in combination with two pistons 4 and 5 arranged within
said cylinder 3, and operated by the right and left screw rod 6, 7, conjointly with
the gear system and motor, whereby a volume of water may be admitted or forced
out of the cylinder 3 as desired for sinking or raising the boat, substantially in the
manner and for the purpose set forth.
2nd. In a submarine boat, in combination an air tight casing conical at each end
and having look outs 25 and 26 on top thereof, an interior cylinder 3 with opening
9 therein, the right and left screw piston rod 6 and 7 and pistons 4 & 5, operating
conjointly with the motor and gear system, substantially in the manner as and for
the purpose set forth.
3rd. In a submarine boat an air tight casing, a cylinder of less size than the
casing located in the bottom thereof, pistons located within the cylinder, a passage-
way extending from the cylinder between the pistons to the outside of the casing,
and means carried within the casing for operating the pistons to admit water to or {
expel it from the cylinder, substantially as described.

page_text: 4th. In a submarine boat, a cylindrical casing conical at both ends, a cylinder
located in said casing with a passageway leading to the outside, means for admitting
water to or expelling it from the cylinder, a motor located in the casing, and means
for connecting the motor with the propelling device or with the water forcing
means as desired, substantially as described.
5th. In a submarine boat with an exterior air tight casing and an interior
cylinder, the right and left screw rod and 7 operating the two pistons in conjoint
operation with the gear system and motor whereby said pistons are caused to recede
or approach each other for the purpose of filling or emptying the cylinder of water
and sinking or raising the boat substantially in the manner specified.
Dated this 22nd day of December 1892.
