PROVISIONAL SPECIFICATION.
Improvements in or connected with Ships and other Vessels.
We, JAMES ARNOTT, of 70 Harlow Terrace, Harrogate, Mechanical Engineer,
and GEORGE AINSWORTH of Midland Buildings Bradford Manufacturer, both
in the County of York; do hereby declare the nature of this invention to be as
follows:-
-
It is well known that a large expenditure of power is required to force a vessel
through the water at any great speed, the resistance being mainly due to the
vessel advancing against such water, the inertia of which is undisturbed.
The object of our invention is to construct apparatus which shall disturb or
break the resisting element (viz. the water) prior to the arrival of the vessel, and
thus the bow of such vessel does not encounter a heavy undisturbed mass of water,
but water which has already been set in motion.
According to our invention we construct a plate or casing in the form or
symmetry of the bow of the vessel, such casing being perforated with holes, which
are preferably directed upwards toward the vessel. This plate or casing is attached
to the bow of the vessel, and at a suitable distance in front of same, so as to leave
a space between for the water to discharge itself.
It will be readily understood that on the vessel moving forward, the plate divides
the water, which rushes through the perforations, and is thus broken before the
arrival of the vessel itself. The vessel as it advances does not therefore encounter
an unyielding mass of water, but water which is already disturbed in a forward
direction, consequently the resistance to be overcome is greatly reduced, and the
power required is very small compared to the speed that may be obtained by the
employment of apparatus as above described.
The thickness of the plate may be varied according to requirements, and it may
be made detachable from the vessel, to be employed or not as desired under varying
circumstances.
Above the plate or attached thereto at the upper part, we provide a tube having
perforations in same; and by feeding oil to such tube by pressure or by a natural
flow, the said oil may be evenly distributed in front of, or on the bow of the vessel,
or on the plate, thus calming rough waves during stress of weather.

Improvements in or connected with Ships and other Vessels.
We, JAMES ARNOTT of 70 Harlow Terrace, Harrogate, Mechanical Engineer,
and GEORGE AINSWORTH of Midland Buildings, Bradford, Manufacturer, both
in the County of York, 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 :-

through the water at any great speed, the resistance being mainly due to the vessel
advancing against water, the inertia of which is undisturbed.
The object of our invention is to construct apparatus which shall disturb or
break the resisting element (riz., the water) prior to the arrival of the vessel, and
thus the bow of such vessel does not encounter a heavy undisturbed mass of water,
but water which has already been set in motion; and also to provide apparatus in
connection with the vessel whereby the waves may be calmed during rough or
boisterous weather.
In order that our invention may be fully understood we will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer to
like parts in all the figures.
Fig. 1 is a side elevation of a vessel shewing our invention applied thereto, and
Fig. 2 is a plan of same. Figs. 3. 4. 5 and 6 are detail views.
According to our invention we construct a plate or casing A in the form or
symmetry of the bow of the vessel B, such casing A being perforated with holes C
which are preferably directed upwards toward the vessel. This plate or casing A
is attached to the bow of the vessel in any suitable way, and at a suitable distance
therefrom, in such a manner as to leave a space D between the plate A and the
vessel B for the water to discharge itself.
By particular reference to Figs. 3. 4. 5 and 6 the plate A will be clearly seen,
and it is obvious that the form of the plate may be varied to suit various types of
vessels to which they are to be applied.
It will be readily understood that on the vessel B moving forward, the plate A
divides the water, which rushes through the perforations C and is thus broken
before the arrival of the vessel itself. The vessel as it advances does not therefore
encounter an unyielding mass of water, but water which is already disturbed in a
forward direction, consequently the resistance to be overcome is greatly reduced,
and the power required is very small compared to the speed that may be obtained
by the employment of apparatus as above described.
The thickness of the plate A may be varied according to requirements, and it
may be made detachable from the vessel, to be employed or not as desired under
varying circumstances.
In order to calm the waves during stress of weather, we employ a perforated
tube E running the full length round the vessel B, the said tube being divided into
sections by means of the cocks F.
Oil is stored in a tank G which is in communication with pipes H, which latter
communicates with the various sections of the perforated tube E, the supply being
regulated by the. cocks J.
It will thus be seen that oil from the tank G may be supplied along the pipes H
to one or more of the various sections of the perforated tube E, and by regulating
the supply by means of the cocks J, oil may be distributed or dispersed in any
required quantity at any suitable part of the vessel.
An auxiliary tube K is situated on the plate A at the bow of the vessel, for the
purpose of distributing oil in front of her, in which case it will be found desirable
to pump or otherwise force the oil in order to project same at a distance.
The plate A being situated outside the tube E, the oil from the said tube E is
fed into the space D between the plate A and vessel B, where it mixes with the
inrushing water, thus relieving materially the vessel from strain during boisterous
weather.
The employment of a natural flow of oil, or of a flow at a pressure caused by
pumping or other means is optional, and may be changed or varied according to the
varying circumstances or conditions of the particular case in question.
Although we have described a particular arrangement of pipes and cocks for
distributing oil on the water from any part of the vessel, yet we do not confine
ourselves to the particular arrangement shewn and described, as it is obvious that
these may be altered or modified without departing from the nature of our
invention.

page_text: 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 :-
--
1. The plate A having holes C, substantially as and for the purposes set
forth.
2. The combination of the plate A, the vessel B and auxiliary tube K,
substantially as and for the purposes set forth.
3. The perforated tube E, cocks F, oil tank G, pipes H. and cocks J,
substantially as and for the purposes set forth.
4. The general arrangement, construction and combination of the various parts
forming improvements in or connected with ships and other vessels, substantially as
herein set forth.
