and Sons, of the Grove, Southwark, in the County of Surrey, Engineer,
for the Invention of "AN IMPROVED MODE OF AND IMPROVEMENTS IN APPA-
RATUS FOR SUPPLYING SURFACE CONDENSERS WITH WATER, PART OF WHICH

PROVISIONAL SPECIFICATION left by the said James Chapman Amos
at the Office of the Commissioners of Patents, with his Petition, on the
21st April 1862.
I, JAMES CHAPMAN AMOS, of the Firm of Easton, Amos, and Sons, of the
Grove, Southwark, in the County of Surrey, Engineer, do hereby declare the
nature of the said. Invention for "AN IMPROVED MODE OF AND IMPROVEMENTS
IN APPARATUS FOR SUPPLYING SURFACE CONDENSERS WITH WATER, PART OF WHICH
IMPROVEMENTS IS APPLICABLE TO BLOWERS AND ROTARY PUMPS GENERALLY," to be as
follows:
The object of this Invention is, first, to provide a ready access to the fan or
impeller of rotary pumps, particularly when applied to the injection of water
into surface condensers, and also, when required, to the fans of blowers. In
the application of rotary pumps or impellers on shipboard, and also on land,
the space that can be afforded them is frequently very limited, and great
Price 8d 1

page_text: difficulty has heretofore been found in providing means for removing the fan
and working parts for examination and repair, the construction of the fan case
(when not divided down the middle) requiring space to be left on both sides,
on one side for the removal of the bonnet of the case, and on the other for
giving the fan axle an endway motion. I now propose to form the case in
such manner that the mere removal of the cover will allow of the removal of
the fan together with its axle and bearings. To effect this object I make the
line of the flange of the cover cut the axis of the fan shaft, or I may carry
that line behind the axle. The withdrawal, therefore, of the bolts which
attach the cover to the other parts of the case will permit of the front of the
case being laid open to such an extent as will allow of the fan being lifted out
of its bearings, without space being required at the sides of the case for the
purpose already mentioned. The above remarks apply also to blowers.
Secondly, I propose, when applying rotary pumps for injecting water into
the surface condensers of marine engines, to draw the water at pleasure either
from the exterior or interior of the. ship. This I effect by mounting the pump
on a suction box fitted with a divided sluice, the compartments of which
communicate respectively with the exterior and interior of the vessel. The
slide of this sluice being actuated by a screw, as usual, may be made to cut off
either or both supplies at pleasure. But when the vessel has sprung a leak
or shipped water the slide is to be shifted so as to admit the bilge water only
to the sluice box. This part of my Invention I propose to carry out also, in
connection with reciprocating pumps.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Chapman Amos in the Great Scal Patent Office on the
21st October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
CHAPMAN AMOS, of the Firm of Easton, Amos, and Sons, of the Grove, South-
wark, in the County of Surrey, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Chapman Amos, Her special license that I, the said James Chapman
Amos, my executors, administrators, and assigns, or such others as I, the said
James Chapman Amos, my executors, administrators, and assigns, should at

page_text: any time agree with, and no others, from time to fime and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain' and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
MODE OF AND IMPROVEMENTS IN APPARATUS FOR SUPPLYING SURFACE CONDENSERS
WITH WATER, PART OF WHICH IMPROVEMENTS IS APPLICABLE TO BLOWERS AND
.1
ROTARY PUMPS GENERALLY," upon the condition. (amongst others), that i, the
said James Chapman Amos, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to, be filed in the. Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters]
Patent...
NOW KNOW YE, that I, the said James Chapman Amos, do hereby
declare, the nature of my said. Invention, and in what manner the same is--to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say):
The object of, this Invention is, first, to provide a ready access to the fan
or impeller of rotary pumps, particularly when applied to the injection of
water into surface condensers,,,and, also, when required, to the fans of blowers.
In the application of rotary pumps or impellers on shipboard, 'and 'also on land,
the space that can be afforded them is frequently, very limited, and great
difficulty has therefore been found in providing means for removing the fan
and, working parts for examination and repair, the construction of the fan case
(when not divided down the middle) requiring space to be left on both sides,
on one side for the removal of the bonnet of the case, and on the other for
giving the fan axle an, endway motion. I now propose to form the case in
such manner that the mere removal of the cover will allow of the removal of
the fan together with its axle and bearing:
:
In the accompanying Drawing, Fig. 1 shews in side elevation fan case
constructed according to this Invention, and Fig. 2 is a plan view of the
same with the cover or bonnet removed, shewing the rotary fan or impeller in
position in the case. By referring to Fig. 1 it will be seen that I make the
line of the flange of the bonnet or cover (which forms an obtuse angle), cut
the axis of the fan shaft. The cover is. of such proportion that when removed
an opening will be provided superior in length to the diameter of the fan.
When, therefore, the fan shaft is disengaged from its bearings it may, with
the fan, be lifted out of the case in the direction of the red lines, Fig. 1; no
space being required at the sides of the case for the purposes already men-

page_text: tioned. I would also remark that the line of the flange cover may, if thought
desirable, be behind instead of cutting the axis of the fan shaft; but I prefer
the arrangement shewn in the Drawing. This arrangement of case, it will be
obvious, is alike applicable to blowers and pumps fitted with rotary impellers
and intended to be used in a confined space, the mere withdrawal of the bolts,
which attach the cover to the other part of the case and keep the impeller
shaft in its bearings, permitting of the front or most accessible part of the case
being laid open to an extent that will admit of the fan or impeller, without
further displacement of parts, being lifted out of its bearings.
Secondly, I propose, when applying rotary pumps for injecting water into
the surface condensers of marine engines, to draw the water at pleasure either
from the exterior or interior of the ship. This I effect by mounting the pump
on a suction box fitted with a divided sluice, the compartments of which com-
municate respectively with the exterior and interior of the vessel, and opening
or cutting off at pleasure the communication between these compartments and
the pump.
Fig. 3 shews in longitudinal' section, and Fig. 4 in cross section a steam
vessel fitted according to this part of the Invention; Fig. 5 is a longitudinal
sectional elevation of the suction or divided sluice box on an enlarged scale.
In Figures 3 and 4, a, a, is a hollow guide or tubular channel set in a line
with the keel and connected by openings with the several water-tight com-
partments b, b, of the steam ship, which openings are closed by valves c, c,
operated through screw rods from the lower deck. The channel a is connected
by branch pipes d, d, with the suction boxes e, c. These boxes are severally
fitted with a vertical partition f, which divides the box into two compartments
g and h, the compartment g being in connection with the bilge-water pipe d,
and the compartment h being open to the water exterior of the ship. A slide
valve i, operated by a rod k, which is screwed into a tapped lug on the back of
the valve, and is supported in suitable bearings in the sluice box, slides the
valve either to or fro as desired, and opens or closes the ports 1, 1, of the
compartments g and has required, thereby admitting to the pump of the
condenser (which pump is mounted on the suction box, as shewn at m, Fig. 4,)
either bilge water or water external of the vessel. This valve may also be
made to cut off either or both supplies at pleasure. But in the event of the
vessel springing a leak or shipping water the slide valve is to be shifted so as
to admit the bilge water only to the sluice box. The bilge water is then
forced by the pump into the surface condenser, and after circulating therein
discharged at the ship's side. By this means- the use of hand pumps on board
steam ships may be to a great extent or wholly avoided, and that without

page_text: putting any additional work on the engines. This principle of utilizing the
bilge water in surface condensers I propose to carry out also in connection
with reciprocating pumps, using for that purpose the arrangement above
described for bringing the pumps into communication with the bilge water or
the water exterior of the ship at pleasure, or any other suitable and analogous
arrangement.
Having now set forth the nature of my Invention of "An Improved Mode
of and Improvements in Apparatus for Supplying Surface Condensers with
Water, Part of which Improvements is applicable to Blowers and Rotary,
Pumps generally," and explained the manner of carrying the same into effect,
I wish it to be understood that under the above in part recited Letters Patent
I claim,
First, constructing the cases of marine and other rotary pumps and blowers
in the manner above described, whereby, on the removal of an easily accessible
cover, the fan may be readily removed for repairs.
Secondly, I claim utilizing the bilge water on board of steam ships, in the
manner and for the purpose above described.
In witness whereof, I, the said James Chapman Amos, have hereunto set
my hand and seal, the Twenty-first day of October, in the year of our
Lord One thousand eight hundred and sixty-two.

No text detected.

page_text: tionable by disclaiming so much of the title of the Patent and Specification
as refers to the mode of supplying surface condensers with water, and to the
construction of blowers, that is to say:
I desire to amend by Disclaimer the title of the Patent, by striking out
the words "improved mode of and," also striking out the final "s" to the
following word improvements;" also to strike out the words "apparatus
for supplying surface condensers with water, part of which improvements
is applicable to blowers and," and to strike out the final word "generally *
when the title will stand thus "An Improvement in Rotary Pumps."
"
And with respect to the Specification, I desire to disclaim, and hereby
disclaim and strike out the now superfluous word "first". at line 18, p. 3
of the printed Specification; also at line 20 the words "and also when
required to the fans of blowers; " at line 30 I strike out the words "fan
case," and substitute the words "rotary pump" in place thereof. AL
line 34 I strike out the word which," and the final "s" in the following
word "forms," also the phrase "cuts the axis of the fan shaft" in lines 34
and 35. In page 4 at line 2, I strike out the words "instead of cutting
the axis of," and also "but I prefer," and continue the erasure to the
remaining descriptive portion of the Specification, striking out also the
several Figures of the Drawing referred to therein.
In the introduction to the claims in page 5, I recite the amended title,
and at line 13 I strike out the word "first," and also the words "and blowers."
And I further strike out the whole of the second claim, when the amended
Specification will stand thus,
The object of this Invention is to provide a ready axis to the fan or
impeller of rotary pumps, particularly when applied to the injection of
water into surface condensers. In the application of rotary pumps or
impellers on shipboard and also on land; the space that can be afforded
them is frequently very limited, and great difficulty has therefore been
found in providing means for removing the fan and working parts for
examination and repair, the construction of the fan case (when not divided
down the middle) requiring space to be left on both sides, on one. side for the
removal of the bonnet of the case, and on the other for giving the fan axle
an endway motion. I now propose to form the case in such manner that the
mere removal of the cover will allow of the removal of the fan, together with
its axle and bearing.
In the accompanying Drawing, Fig. 1 shews in side elevation a fan case
of a rotary pump constructed according to this Invention, and Fig. 2 is a plan
view of the same with the cover or bonnet removed, shewing the rotary fan

page_text: or impeller in position in the case. By referring to Fig. 1 it will be seen that
I make the line of the 'flange of the bonnet or cover (which forms an obtuse
angle) cut the axis of the fan shaft. The cover is of such proportion that when
removed, an opening will be provided superior in length to the diameter of the
fan. When therefore the fan shaft is disengaged from its bearings it may
with the fan be lifted out of the case in the direction of the red lines, Fig. 1,
no space being required at the sides of the case for the purposes already men-
tioned. I would also remark that the line of the flange cover may if
thought desirable be behind, instead of cutting the axis of the fan shaft.
Having now set forth the nature of my Invention of "An Improvement in
Rotary Pumps," and explained the manner of carrying the same into effect, I
wish it to be understood that under the above in part recited Letters Patent. 1
claim constructing the cases of marine and other rotary pumps in the manner
above described, whereby, on the removal of an easily accessible cover, the fan
may be readily removed for repairs.
In witness whereof, I, the said James Chapman Amos, have ⚫ hereunto
set my hand and seal, this Seventh day of December, in the year
of our Lord One thousand eight hundred and sixty-three.
