PROVISIONAL SPECIFICATION.
A New or Improved Oil Shell or Projectile for Distributing Oil on
the Surface of Water.
I, ROBERT WHITBY 49 Cranmer Road Forest Gate Essex Engineer R.N.
do hereby declare the nature of this invention to be as follows
:-
This invention consists in the construction and arrangement of a projectile or
shell containing oil so that when the shell is fired from a gun, suitable apertures are
opened in the shell through the action of the firing charge upon mechanism to be
more fully described hereafter; the oil being free to distribute itself through said
apertures in the shell and the same is carried out in the following manner.
I provide a cylindrical or other shaped receptacle having a tube of any suitable
section running through same from end to end thus forming a space or compartment
for the reception of the oil. One end of this receptacle is provided with suitable
perforations which communicate with the oil compartment. The tube aforesaid is
also provided with suitable perforations which communicate with the oil compartment
aforesaid. A rod or piston of a section similar to that of the tube aforesaid, passes
through the said tube. One end of this rod carries a plate of a suitable size &
shape which plate covers the apertures in the end of the receptacle and is sealed
hermetically thereto; the other end of the rod or piston terminates at the other end
of the receptacle and is also hermetically sealed at the end of the tube aforesaid.
It will be seen that when the receptacle is placed in a gun with its perforated and
plate covered end next the muzzle and fired therefrom, the rod carrying the cap
will, owing to its lighter weight be blown out of the receptacle by the action of the
charge upon the end of the rod aforesaid and the oil free to distribute itself. The
receptacle is so weighted as to cause the perforated end to remain upwards while
the receptacle is sinking in the water which sinking takes place owing to the dis-
placement of the oil from the receptacle through the apertures in the end of same;
the water entering the receptacle through the perforations in the tube aforesaid
running through the receptacle. If desired I provide a band of suitable material
running round the receptacle at a convenient part thereof which band engages with
the rifling when such a gun is used thus imparting rotary motion to the projectile.
If desired I may dispense with the cover plate aforesaid & end perforations and
utilize the perforations in the tube aforesaid for purposes of oil distribution.

5 A New or Improved Oil Shell or Projectile for Distributing Oil on
the Surface of Water.
I, ROBERT WHITBY (late R.N.) 49 Cranmer Road Forest Gate Essex,
Engineer, 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 :-
This invention consists in the construction and arrangement of a projectile or
shell, containing oil, so that when the shell is fired from a gun, suitable apertures
are opened in the shell through the action of the firing charge upon mechanism to
מ

page_text: be more fully described, hereafter, the oil being free to distribute itself by escaping
through the said apertures in the shell and tube from the moment of leaving the
gun, and the same is carried out in the following manner.
I provide a cylindrical or other shaped receptacle having a tube of any suitable
section running through same from end to end, thus forming a space or compartment
for the reception of the oil. One end of this receptacle is provided with suitable
perforatious which communicate with the oil compartment. The tube aforesaid is
also provided with suitable perforations which communicate with the oil compart-
ment aforesaid. A rod or piston of a section similar to that of the tube aforesaid,
passes through the said tube. One end of this rod carries a plate of a suitable size
and shape which plate covers the apertures in the end of the receptacle and is sealed
hermetically thereto, the other end of the rod or piston terminates at the other
end of the receptacle, and is also hermetically sealed at the end of the tube
aforesaid. It will be seen that when the receptacle is placed in a gun, with its
perforated and plate covered end next the muzzle & fired therefrom, the rod
carrying the cap will, owing to its lighter weight be blown out of the receptacle by
the action of the charge upon the end of the rod aforesaid and the oil free to
distribute itself. The receptacle is so weighted, as to cause the perforated end to
remain upwards, while the receptacle is sinking in the water, which sinking takes
place, owing to the displacement of the oil from the receptacle through the apertures
in the end of same, the water entering the receptacle through the perforations in the
tube aforesaid running through the receptacle. If desired I provide a band of
suitable material running round the receptacle at a convenient part thereof which
band engages with the rifling, when such a gun is used, thus imparting rotary
motion to the projectile, so that it can be thrown a considerable distance in aid of
persons in distress or ships in peril. If desired I may dispense with the cover plate
aforesaid & end perforations and utilize the perforations in the tube aforesaid for
purposes of oil distribution.
Referring to the annexed drawings
Fig. 1. is a longitudinal section of my invention.
Fig. 2. side elevation of rod & cover plate detached.
Fig. 3. modified arrangement in which the rod and cover plate is dispensed with.
Figs. 4 & 5 further modified arrangements.
Fig. 6 plan view of Figure 1.
Fig. 7. plan view of Figure 3.
Fig. 8. plan view of Figure 4.
Fig. 9. view of my invention in operation.
Referring to Figure 1.
a is the shell or casing provided with inner tube 6 & perforations c in same.
d perforations in end of shell. e rod carrying cover plate being sealed in any
convenient manner at g & h.
Referring to Figure 3.
In this case the cover plate f & apertures d are dispensed with & the tube b is
provided with the annular recess & projection or rim j to ensure proper sealing.
In this case & also 4 & 5 the rod e is replaced by a hollow tube e¹ closed at both
ends.
Referring to Figure 4.
In this case a screw plug k is inserted having square 1 for insertion of key, in the
end of the tube e' which can be removed when desired.
Referring to Figure 5.
In this case, the inner tube is provided with a thread m, engaging with a
corresponding thread in the case on shell ends. In Figures 1. 3 & 4 the inner
tube may be fixed in the shell in any convenient manner, such as soldering, folding
or formed integral therewith. These projectiles also form a convenient method of
storing oil and can be emptied if wanted for another purpose and refilled. sealing
material.

page_text: 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.
1. The combined construction and arrangement of the various parts, substantially
as described and shewn.
2. In oil shells or cartridges, an outer casing provided with an inner tube having
perforations, said casing having a perforated end in combination with a rod &
cover plate, substantially as described & shewn.
3. In oil shells or cartridges, an outer casing provided with an inner tube, having
perforations, grooves & projections in combination with a tube closed at both ends
& engaging in said inner tube, substantially as described & shewn.
4. In oil shells or cartridges an outer casing provided with an inner tube having
perforations, grooves & projections, said tube screwing into the ends of the casing,
with or without a screw for retaining a tube closed at both ends in the inner tube
aforesaid & in combination therewith.
