page_text: LETTERS PATENT to John Richardson, Engineer to the Firm Robey
and Company, Limited, Perseverance Works, Lincoln, and Charles
Julius Ball, of 21, New Bridge Street, Blackfriars, in the City of
London, Civil Engineer, for the Invention of "IMPROVED ARRANGE-
MENTS OF ENGINE AND BOILER WITH AIR OR GAS COMPRESSING APPARATUS IN
Sealed the 10th August 1875, and dated the 16th February 1875.
PROVISIONAL SPECIFICATION left by the said John Richardson and
Charles Julius Ball at the Office of the Commissioners of Patents,
with their Petition, on the 16th February 1875.
We, JOHN RICHARDSON, Engineer to the Firm Robey and Company,
Limited, Perseverance Works, Lincoln, and CHARLES JULIUS BALL, of
21, New Bridge Street, Blackfriars, in the City of London, Civil
Engineer, do hereby declare the nature of the said Invention for
"IMPROVED ARRANGEMENTS OF ENGINE AND BOILER WITH AIR OR GAS COMPRESSING
APPARATUS IN COMBINATION," to be as follows:-

page_text: with air or gas compressing apparatus in combination, and consists in
fitting the engine upon a foundation plate or bed, and below the barrel
of the boiler when a horizontal boiler is used with the shafts and other
gearing in proximity, so as to be independent of such boiler, which rests
fore and aft upon the foundation. The smoke box end rests and is
bolted down upon the steam cylinders, the fire-box end resting direct
upon the foundation, which is preferably hollow and forms a feed water
tank.
The engine proper is so fitted that it operates upon air or gas com-
pressing apparatus fitted as part of the structure, and from which air or
gas compressing apparatus machinery or appliances can be driven. The
combination is applicable to the vertical type of boilers in a corre-
sponding manner. The engine can be driven to work machinery when
disconnected from the air pump..
The air or gas compressing apparatus is of a novel character, as is
described in the Specification of Patent No. 1749, of the year 1874,
granted to Charles Julius Ball, one of the parties hereto.
The arrangement of the compressing apparatus being necessarily
made in conformity with the class of engine boiler and foundation
employed.
The apparatus consists mainly of a pumping cylinder open at one end,
and containing a piston actuated directly by a connecting rod driven by
a crank formed upon a suitable crank shaft carrying a heavy fly wheel.
The air or gas cylinder is fixed to the bed plate, also the cylinder of a
steam engine, which causes the fly wheel to revolve by means of a 2
connecting rod working upon another crank formed upon the same
aforesaid shaft. The pump cylinder is surrounded by a cistern, which is
kept filled with cold water, and the water having free access to the
inside and outside of the cylinder and piston they are kept cool and
prevent the ill effect of the heat given out by the air during compression.
The closed end of the pump is fitted with inlet and outlet valves (which
may also be surrounded by a water cistern) so arranged that little or no
clearance is allowed between them and the pump piston when the latter
is at the end of its stroke, and nearly the whole of the useful effect of
the pump is thus utilized. The bearing of the connecting rod which 8
drives the piston may be adjustable.

page_text: In order to absorb the heat evolved by the compression of the air the
opening to the inlet valve is in the form of a tube, and water in the
form of spray is forced with the inflowing air into this tube, such jet
disseminating and carrying with it a sufficient quantity of water which
is allowed to fall in front of it (or to be raised by it from a small depth)
through a pipe (or pipes), the end of which is immediately in front of
the jet and at right angles to it. By this arrangement the inflowing air
is saturated with moisture in a fine state of division.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Richardson and Charles Julius Ball in the
Great Seal Patent Office on the 16th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
.RICHARDSON, Engineer to the Firm Robey and Company, Limited,
Perseverance Works, Lincoln, and CHARLES JULIUS BALL, of 21, New
Bridge Street, Blackfriars, in the City of London, Civil Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of February, in the
year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said John Richardson and Charles
Julius Ball, Her special licence that we, the said John Richardson and

page_text: Charles Julius Ball, our executors, administrators, and assigns, or such
others as we, the said John Richardson and Charles Julius Ball, our
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 "Im-
PROVED ARRANGEMENTS OF ENGINE AND BOILER WITH AIR OR GAS COMPRESSING
APPARATUS IN COMBINATION," upon the condition (amongst others) that we,
the said John Richardson and Charles Julius Ball, or one of us,
our executors or administrators, by an instrument in writing under
our, or one of our, 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 we, the said John Richardson and Charles
Julius Ball, do hereby declare the nature of said Invention, and in
.what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to
say:―
This Invention relates to improved arrangements of engine and boiler
with air or gas compressing apparatus in combination, and consists,
substantially as shown in the accompanying Drawings, in fitting the
engine A upon a foundation plate or bed B, and below the barrel C of
the boiler when a horizontal boiler is used, as in Figures 1 and 2, with
the shaft D and other gearing in proximity, so as to be independent of
such boiler, which rests fore and aft upon the foundation B. The smoke
box end E rests and is bolted down upon the steam cylinder A, the fire-
box end F resting direct upon the foundation, which is preferably hollow
and forms a feed water tank.
The engine proper, single or double-action, is so fitted that it operates
upon air or gas compressing apparatus G, fitted as part of the structure
as shown, and from which air or gas compressing apparatus G machinery
or appliances can be driven. The combination is applicable to the
vertical type of boilers, as in Figures 3 and 4, in a corresponding manner.

page_text: a pump.
The air or gas compressing apparatus is of a novel character, as is
described in the Specification of a Patent, No. 1749, in the year 1874,
granted to Charles Julius Ball, one of the parties hereto, the arrangement
of this compressing apparatus being necessarily made in conformity with
the class of engine boiler and foundation employed.
The apparatus consists mainly of a pumping cylinder G open at one
end, and containing a piston actuated directly or indirectly by a con-
necting rod driven by a crank formed upon a crank shaft H, carrying
one or more heavy fly wheels I. The air or gas cylinder or cylinders G
is fixed to the bed plate, also the cylinder A of a steam engine, which
causes the fly wheel to revolve by means of a connecting rod working
upon another crank formed upon the same shaft. The pump cylinder is
surrounded by a cistern J, which is kept filled with cold water, and the
water having free access to the inside and outside of the cylinder and
piston they are kept cool and prevent the ill effect of the heat given out
by the air during compression. The closed end of the pump is fitted
with inlet and outlet valves (which may also be surrounded by a water
cistern), so arranged that little or no clearance is allowed between them
and the pump piston when the latter is at the end of its stroke, and
nearly the whole of the useful effect of the pump is then utilized.
The bearing of the connecting rod which drives the piston may be
adjustable.
In order to absorb the heat evolved by the compression of the air the
opening to the inlet valve is in the form of a tube K, and water in the
form of a minutely divided spray is sucked or forced in with the
inflowing air into this tube, such spray being obtained by a small jet
of compressed air being made to impinge at right angles or otherwise on
the edge of a small water pipe carrying with it a sufficient quantity of
water, which is allowed to fall in front of the air jet (or to be raised by
it from a small depth). There can be one or several pipes. By this
arrangement the inflowing air is saturated with moisture in a fine state
of division, which enables it to absorb at once the heat evolved by the

page_text: independently of the boiler upon a foundation plate or bed, substantially
as described and shown.
In witness whereof, we, the said John Richardson and Charles
Julius Ball, have hereunto set our hands and seals, this Thirteenth
day of August, One thousand eight hundred and seventy-five.
