Improvements in Apparatus for use in Effecting Ejectment or
Removal of Ashes, Grain, and other matters from Ships and
from and in other Structures and for other like purposes.
I MYER LEWIS ISAACS of No. 40 Furnival Street in the County of Middlesex
Wholesale Optician 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 said invention consists of apparatus for use in effecting ejectment or
removal of ashes grain and other matters from ships and in effecting ejectment of
ashes grain sawdust and other matters from mills and other structures and in
effecting removal of such matters in mills and other structures and for other like
purposes the said apparatus being so constructed that when it is connected with a
supply of steam or compressed air and with suitable delivery conduits and the
matters to be ejected or removed are supplied to it the passage through it of the
steam or compressed air in the form of a blast effects the ejectment or removal of
the said matters as required.
In the accompanying drawings two forms of apparatus constructed according to
my invention are illustrated.
Figure 1 of the said drawings is a central vertical section of one of the said
forms of apparatus showing connections suitable in cases where the said apparatus
is to be used for the ejectment of ashes and the like from the stoke-hold of a ship
through the side thereof.
Figure 2 is a horizontal section of the said apparatus taken on the line A A.
Figure 1.
Figure 3 is a plan view of a portion of the apparatus illustrated in Figure 1.
Figure 4 is a vertical section of the other of the said forms of apparatus and
portions of some of the connections required when the apparatus is in use the
section being taken on the line 13 B Figure 5 which is a plan of the same the
said connections being shown in section.
Figure 6 is a section of a portion of the said apparatus the section being taken
on the line C C, Figure 4.
In the following description of the said drawings the parts thereof are referred
to by the letters and figures marked thereon. The same letters and figures of
reference indicate the same parts in all the figures of each form of apparatus.
I will first describe the form of apparatus illustrated in Figures 1, 2 and 3 of the
drawings. Referring to the said figures a is the base of the apparatus consisting
of a pan shaped receptacle into which the matters to be ejected or removed are
placed or delivered the said receptacle resting on the flooring plates of the
stoke-hold of the ship. To a bracket c formed on the said part a is secured the
body of the ejector apparatus consisting of a cylindrical tube d having a flange d'
around its upper end the interior of which tube communicates with an annular
chamber e formed around it and provided with a flanged nozzle e' which is connected
to a supply of steam or air under pressure when the apparatus is set up for use.
fis a bush having a screw thread formed on its exterior which is engaged with a
screw thread formed on the inner wall of the chamber e. Part of the said bush /
projects below the chamber e and is provided with a flange having radial
holes formed in it for the reception of a lever or "tommy" by means of
which the said bush may be turned in order to adjust its position relatively to the
[D7

page_text: lower part of the tube d. 7 is a ring connected to the upper end of the bush
which ring obstructs to a greater or less extent the communication between the
tube d and the chamber e according to the position of the bush f. As shown in
Figure of the drawings the tube d and chamber e and bush fare all of equal
internal diameter and the upper face of the ring g and the part of the tube d which
is opposed to it are of conical form consequently when the bush is in such a
position that the said faces of the said parts are not in contact the space between
them constitutes a passage h communicating between the chamber e and the interior
of the tube d the inward direction of which passage is upward. The apparatus
consisting of the parts a d f g herein before described is connected by means of
flanged tubes i to a tube provided with a sluice valve and secured around an
orifice in the side of the ship by means of bolts and nuts m m. n is a ring secured
by rivets n n to the outerside of the ship around the said orifice for the purpose
of strengthening the plate in which the said orifice is cut. A plan or face view of
the cover or "bonnet " o of the box in which the screwed stem of the sluice
valve works is shown in Figure 3.
When the apparatus is set up as illustrated in the drawings and the nozzle e¹ is
connected with a supply of steam or air under pressure the said apparatus is ready
for use and is used and acts as follows. The ashes or other matters to be ejected
are deposited in the pan a the steam or air under pressure is admitted to the
chamber e and the sluice valve is opened. The steam or air admitted to the
chamber e rushes therefrom through the passage in an upward direction into
and through the tubes diij and the orifice in the side of the ship causing
current of air to pass between the edge of the pan a and the lower end of the
bush through the said bush into and through the tube d which current of air
carries the ashes or other matters deposited in the said pan a into the said tube d
from which they pass through the tubes iij out of the ship with the steam or
compressed air from the chamber e.
iL
The force of the blast of steam or compressed air issuing from the chamber e
through the passage may be varied as required by increasing or decreasing the
sectional area of the said passage which is effected by turning the bush f so as to
lower or raise the ring y.
I will now describe the form of apparatus illustrated in Figures 4 and 5 in which
apparatus the blast of steam or air issues from the mouth of a tube communicating
with a conduit formed in the pan of the apparatus and opening under a hood
supported above the said pan to which hood tubes leading to the outlet in the
ship's side are connected.
Referring to the said Figures 4 and 5 p is the pan or receptacle for the matters
to be ejected. is the conduit formed in the said pan the outer end of which
conduit has a flange formed on it to admit of its connection with the pipe by which
steam or compressed air is conveyed to the apparatus. is the tube from
which the blast issues the mouth of the said tube being of conical form internally
and having mounted concentrically in it a conical blocks supported by rods t
connected to the said tube as shown in Figure 6 which is a horizontal section
of the blast tube and conical block taken on the line CC Figure 4.
hood into which the blast is delivered. The said hood is supported above the
pan p by a bracket p' formed thereon and is connected at its upper end to pipes
leading to an outlet as in the arrangement illustrated in Figure 1 a portion of one
of which pipes is shown at v in Figures 4 and 5.
י
u is the
The action of this form of apparatus is as follows. The blast of steam or air
passes from the tube in an upward and outward direction into the hood u and
tlience through the. pipes connecting it to the outlet and the ashes and other
matters which are deposited in the pan p are caused to pass to and through the
hood u to the said outlet as hereinbefore described with reference to the
arrangement illustrated in Figure 1.
Both the forms of apparatus hereinbefore described may be used for discharging
ashes or other matters from ships below the water line if desired. Both the said

page_text: forms of apparatus arc also suitable for use in all cases where matters capable of
being conveyed through a tube shaped conduit by a strong current of air are
required to be removed from ships and from and in other structures and for other
like purposes.
Although in the accompanying drawings the parts of the apparatus above the
pan are shown as supported simply by a bracket formed on the pan it will be
understood that the said parts may be otherwise supported and that additional
support may be provided for the said parts if desirable.
In Figure 1 of the accompanying drawings a suitable form of valve for closing
the outlet pipes connected to the ejecting apparatus is illustrated. I would
however observe that the said valve forms no part of this invention and that I make
no claim to it either in combination with the ejecting apparatus hereinbefore
described or otherwise.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be or may be performed I wish it to
be understood that the said invention is not restricted to the precise forms of
apparatus hereinbefore described and illustrated in the accompanying drawings as
considerable variations may be made without departing from the nature of the said
invention but I declare that I claim -
First Apparatus constructed substantially as herein before described for use
in effecting ejectment or removal of ashes grain and other matters from ships and
from and in other structures and for other like purposes that is to say apparatus so
constructed that the passage through it of a blast of steam or air causes ejectment
or removal of the matters as required when they are supplied to the said
apparatus.
Secondly-The general combination and arrangement of the parts ad ef g of
the apparatus illustrated in Figure 1 of the accompanying drawings for use in
effecting ejectment or removal of ashes grain and other like matters from ships and
from and in other structures and for other like purposes.
Thirdly The general combination and arrangement of parts constituting the
apparatus illustrated in Figures 4 and of the accompanying drawings for use in
effecting ejectment or removal of ashes grain and other like matters from ships and
from and in other structures and for other like purposes.
