Improved Means for Heating Air and other Gases for Heating
Purposes Generally.
I JOHN ALEXANDER ROSSITER of Newera Elliya, Ceylon, Planter do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to obtain a supply of heat by mechanical means,
working, for that purpose on the principle, of compression.
In carrying out my invention, 1 employ, say, a pair of vertical cylinders
fitted with pistons, the rods of which carry antifriction bowls at their upper
ends.
Mounted above these cylinders is a V shaped balanced beam, which is intended
to bear against the antifriction bowls of the piston rods, and alternately to depress
the pistons in their cylinders.
Below each cylinder is a water tight chamber, fitted severally with a coil of pipe,
which pipes connect with the bottom of their respective cylinders.
The other ends of these coils of pipe conuect with a compression pump, which
supplies them with compressed air or gas, as may be desired.
The air or gas flows from these coils into their respective cylinders, and thus
balances the pistons of the two cylinders.
If, now, pressure is applied to one end of the balanced beam, it will force down
the piston below the depressed end of the beam, and thereby compress the air
contained in the cylinder, and in the pipe communicating therewith.
In proportion to the pressure applied to the air or gas, the temperature of the
same will rise, and the heat thus obtained will be taken up by the water surrounding
the coil.
In like manner, when the load is shifted to the opposite end of the beam, com-
pression of the air or gas in the other cylinder will cause a rise of temperature in
the same, which will be taken up in like manner by the water in the chamber
surrounding the coil.
It will be obvious that the heat thus generated may be applied to the raising
of steam for the working of the apparatus itself, as well as to other uses in
the arts.

Improved Means for Heating Air and other Gases for Heating
Purposes Generally.
1 JOHN ALEXANDER ROSSITER of Newera Elliya, Ceylon, Planter, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to obtain a supply of heat by mechanical means
working, for that purpose, on the principle of compression.
In carrying out my invention, 1 employ, say, a pair of vertical cylinders,
fitted with pistons, the rods of which carry antifriction bowles at their upper
ends.
Mounted above these cylinders is a V-shaped balanced beam, which is intended

page_text: the pistons in their cylinders.
Below each cylinder is a steam-tight chamber, fitted severally with a coil of pipe,
which pipes connect with the bottom of their respective cylindors.
The other ends of these coils of pipe connect with a compression pump, which
supplies them with compressed air or gas, as may be desired.
The air or gas flows from these coils into their respective cylinders, and thus
balances the pistons of the two cylinders.
If, now, pressure is applied to one end of the balanced beam. it will force down
the piston below the depressed end of the beam, and thereby compress the air
contained in the cylinder and in the pipe communicating therewith.
In proportion to the pressure applied to the air or gas, the temperature of the
same will rise, and the heat thus obtained will be taken up by the water or other
body surrounding the coil.
In like manner, when the lond is shifted to the opposite end of the beam, com-
pression of the air or gas in the other cylinder will cause a rise of temperature in
the same, which will be taken up in like manner by the water or other body in the
chamber surrounding the coil.
It will be obvious that the heat this generated may be applied to the raising
of steam for the working of the apparatus itself, as well as to other uses in
the arts.
In the accompanying drawing,
Fig. 1 shews in side elevation, and
Fig. 2 in sectional elevation, an arrangement of apparatus for carrying out
the object of my invention, and corresponding with the description given above.
1 should here state, that my invention is based on the theory that after each
compression of the air or gas contained in the machine to produce heat, which is
absorbed by water or other body, and the subsequent expansion of the air, which
abstracts heat. there is always a residuum of heat left, and it is this residuum which
propose to apply for heating purposes generally.
To this end, have devised the arrangement of apparatus which I will now
proceed to explain.
A Aare a pair of vertical cylinders fitted with pistons, the rods a a³ of which
carry, at their upper ends, anti friction bowles.
These cylinders are mounted upon chambers B B', which rest upon a bed
plate.
Standing up from this bed plate is a pair of standards cc, which extend up above
the range of the piston rods, and carry the rock shaft D of a vibrating V-shaped
beam D¹.
This beam stands over the centres of the cylinders A A', and its onds bear upon
the bowles of the piston rods.
Keyed to the shaft D, is an arm d, from which depends n connecting rod E, the
strap of which embraces an excentric E', mounted on a shaft E³, which has its
bearings in brackets on the bed plate.
Rotary motion is imparted to this excentric by a band and pulley, or otherwise,
for the purpose of rocking the boam D', and thus alternately depressing the pistons
of the cylinders A A¹.
The chambers B B are fitted with coils of pipo F F', which severally connect
with their respective cylinders, and with a pipeƒƒ".
C is a force pump connected by pipes with the pipes ff'.
This pump is for the purpose of supplying air or gas at a pressure to the
coils, and, through them, to charge the cylinders A. A for, say, one half
of their capacity, the pistons being, at the time of supplying the air or gas, at their
intermediate position.
The chambers B B are charged with water or equivalent heat-absorbing body,
and the supply is maintained throughout the working of the apparatus.
Steam or other hot body is taken off from these chambers for utilization by

page_text: the pipe b, and escape valves are provided at 6* to secure the safety of the
apparatus.
It will now be understood that on the rocking of the beam D' being started, the
pistons will be alternately depressed in their cylinders, and the force of expansion
of the compressed air or gas in one cylinder bearing up the piston rod against one
limb of the V-shaped beam, will serve to compress the air or gas in the other
cylinder, for the action of the expansion of the air or gas in one cylinder is equal
to the compression of the gas in the other.
Thus, in whatever position the ends of the beam are placed, by reason of the
varying volume of the contents of the cylinders, a perfect balance is always
sustained.
My object in employing the excentric is to apply a small power to turn the scale,
and give the beam the rocking motion necessary for depressing the pistons in their
respective cylinders, and thereby generating heat, which, as before stated, can be
used for heating purposes generally, such as producing steam or heating air or any
other body.
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 :-
The means above described for obtaining heat for heating purposes generally
through the
agency of pressure.
