Year: 1859

page_text: LETTERS PATENT to Elias Sloman, of Upper East Smithfield, in the
County of Middlesex, for the Invention of "AN IMPROVED FEED WATER
AND HEATING APPARATUS."-A communication from Gottfreyd May,
resident at Magdeburch, in the Kingdom of Prussia.
Sealed the 10th February 1860, and dated the 18th August 1859.
PROVISIONAL SPECIFICATION left by the said Elias Sloman at the
Office of the Commissioners of Patents, with his Petition, on the 13th
August 1859.
I, ELIAS SLOMAN, of Upper East Smithfield, in the County of Middlesex,
do hereby declare the nature of the said Invention for "AN IMPROVED FEED
WATER AND HEATING APPARATUS," (a communication from Gottfreyd May,
resident at Magdeburch, in the Kingdom of Prussia,) to be as follows:-
This Invention has for its objects the feeding of boilers, either marine, loco-
motive, stationary, or portable, and can be applied to either the one or the
other, at the same time heating the feed water before entering the boiler, and
preventing the bursting thereof. The manner in which these objects are
effected is as follows:-At the side of the boiler or other convenient part is
placed a short pipe having a tap or cock at each end; to these taps or cocks
are attached short levers, the ends of which are fastened to a connecting rod;
the taps or cocks have only one water way each, and are in opposite directions

page_text: so that as they both move simultaneously, one is open when the other is shut,
and vice versâ the water passes in at an entrance in a pipe below the feed
water pipe, and traverses through until it reaches another pipe above, whence
it makes its exit from an outlet into the boiler, the water thus being
previously heated. By this means the ordinary feed pump is entirely dis-
pensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Elias Sloman in the Great Seal Patent Office on the 13th
February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELIAS
SLOMAN, of Upper East Smithfield, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of August, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Elias Sloman, Her special licence that I, the said Elias Sloman, my
executors, administrators, and assigns, or such others as I, the said Elias
Sloman, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter 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 FEED
WATER AND HEATING APPARATUS," (a communication from Gottfreyd May,
resident at Magdeburch, in the Kingdom of Prussia) upon the condition
(amongst others) that he, the said Elias Sloman, his executors or adminis-
trators, by an instrument in writing under his or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said
Invention, 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 Elias Sloman, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, that is to say:-

page_text: This Invention has for its objects the feeding of boilers, either marine, loco-
motive, stationary, or portable, and can be applied to either the one or the
other, at the same time heating the feed water before entering the boiler, and
preventing the bursting thereof.
In order to explain the said Invention as completely as possible, I now pro-
ceed to describe the best means I am acquainted with for carrying the same
into practical effect, reference being had to the illustrative Sheets of Drawings
hereto annexed, and to the numeral figures and letters of reference marked
thereon respectively as follows:-
The feed water and heating apparatus supplies the boiler to which it is
attached in such a manner and at such a rate that the water level does not
şink below its proper minimum height, when the greatest consumption of steam
takes place; also that it cannot rise above its proper maximum point when the
least amount of steam is consumed, thereby keeping the water on the same
level when the consumption of steam is normal. The apparatus heats the
water up to boiling point without any particular consumption of steam.
The apparatus consists of a vessel of any suitable form, communicating
alternately with the boiler and a water reservoir, as shewn in the accom-

page_text: position y, before the crank has reached the position a escapes through the
openings d and e into the vessel G, which is surrounded by the reservoir H:
The steam condenses in G, flows back at the next movement through the
tube f into the tap. The steam which enters G heats the water surrounding
it in the reservoir H. L is a tube in the boiler open at each end preventing
the dirt or scum which is flowing on the surface of the water from entering
the apparatus; V is a valve for shutting off the communication between the
apparatus and the boiler. The hollow space h in the cock M is used for
discharging the tap, and is connected with the boiler by the canal i. The
réservoir His to be kept well filled up with water, the tube T serving as
an outlet.
Figure 4 represents the before described apparatus fitted upon the top of
the boiler, corresponding letters of reference denoting the same parts as lin
Figures 1, 2, and 3. The water flows here from the tap through the tube. ĺ
into the boiler, which tube ends at the point of the normal water level A, B.
A further feeding or flowing out of the water ceases as soon as the outlet of Z
reaches the water. The wider tube L, which is open at each end being sup-
ported by rods projecting from the tube / prevents the dirt from the surface of
the water entering the apparatus.
Figures 5, 6, 7, and 8 represent the same apparatus as Figures 1, 2, and 3,
but here is applied the slide N' in lieu of the cock or tap, which is analogous
with Figure 1 of the described apparatus, being moved by the crank K, taking
up water when its opening is placed before the inlet opening a, and the water
flows out into the boiler when it is placed before the outlet opening b. The
hollow slide N conducts (also in this case) the steam through the openings &
and e, and the tubes 9 and f into the condensing vessel G, at the next move"
ment the condensed steam flows again through. f into the hollow space of
slide N. When the water level reaches its normal height shewn by the'
line A, B, the feed water ceases likewise to enter the boiler when this apparatus
is applied, and the same may also be placed at the top of the boiler in the
manner shewn and described at Figure 4.
.
Each of the before-mentioned apparatuses may also be applied with the
same safety and advantage without the use of the condenser G as the steam
entering the tap N from the boiler is conducted through the opening a into the
water of the reservoir H, and thus heating it. It is essential that a continued
uniform motion of the crank is obtained to keep the water at its proper level. ⚫
At Sheet 2 the Figures represent different views of an apparatus in which.
the vessel N is applied instead of the tap or cock and hollow slide n, it

page_text: communicates alternately (through the canal a and b) with the water reser-
voir H, and the boiler through 6 shutting off a. The steam producing an
opening d causes the water to flow easier. from the vessel. N into the
boiler; the slide e closes this opening when by the motion of the slide [n
the water reservoir H is communicating with the vessel N, and it is open
when the boiler is communicating with the vessel N. The valves V and
V₁ are placed between the slide box and the boiler connecting them both.
The steam enters from the upper part of the boiler through the tube L, and
the valve V, and the water enters the boiler through the valve V. The
line A, B, indicates the normal water level; A', B', is the highest line, and
A, B, is the lowest line between which the apparatus (continually in uniform
motion) keeps the water level, even when the steam consumption is the most
irregular possible, whereas when the steam consumption is regular, it keeps
also the water continually at its normal or proper level. The circular motion
of the slide n is caused by the shaft or spindle W, and the crank K connected
to it, the latter moving with the pivot k in the conducting curve E, E, makes a
backward and forward motion as often as the curve is turned once round by
means of the pully Z. The conducting curve E, E, is of such an arrange-
ment that in its first quarter of a revolution, or that of the pulley, it moves the
crank K. forward, in its second quarter of a revolution the slide rests, leaving
time for the water to flow from N into the boiler, in the third quarter of a
revolution it moves the crank K backward, and in the last quarter, the slide
again rests, leaving proper time for the water to flow from H into N. It is
evident also that with this apparatus the pulley has to be kept continually
moving, no matter in which direction. Cocks or taps may also be applied in
this apparatus instead of the slides. If this apparatus be placed upon the top
of the boiler, as shewn at Figure 4, Sheet 1, the entrance of the water is
through the valve V, and a tube reaching below the level of the lowest water
height, whereas the steam enters through the valve V¹, and a tube reaching
the highest water height or line. The handle as shewn at Figures 2, 4,
and 5, of Sheet 2, is to be applied to each of the before-mentioned apparatuses,
so that water can be supplied to the boiler by hand when the other motive
power is temporarily stayed.
Having now fully described the nature and object of the said Invention of
"An Improved Feed Water and Heating Apparatus," together with the
manner in which the same is to be performed, I would remark in conclusion
that I do not confine or restrict myself to the precise details herein described,
and shewn in the accompanying Sheets of Drawings, as many slight modifi-

page_text: cations may be made therein without in any way departing from the principle
of the Invention, but what I claim as the Invention intended to be secured to
me by the herein in part recited Letters Patent is the method of heating the
feed water, and supplying the same to the boiler, keeping it at its normal
height in the manner and for the purposes shewn by the accompanying
Drawings, and herein. fully described and set forth.

One thousand eight hundred and sixty.
