the Commissioners of Patents, with his Petition, on the 14th
January 1873.
I, PETER SALMON, Engineer, of No. 5, Mabledon Place, Burton
Crescent, London, W.C., in the County of Middlesex, do hereby declare.
the nature of the said Invention for "IMPROVEMENTS IN STEAM BOILERS
AND OIL GAS APPARATUSES, AND IN OIL GAS ENGINES AND BOILERS, AND IN THE
APPARATUSES CONNECTED THERE WITH, PARTLY TO WARM, VENTILATE, AND LIGHT
RAILWAY CARRIAGES AND OTHER VEHICLES," to be as follows:-
These improvements are applicable,―
Firstly. To steam boilers and oil gas apparatuses to produce gas for
lighting, cooking, warming, smelting ironstone, heating iron or other
metals for rolling, conversion of iron into steel, or other purposes.
And Secondly. To oil gas engines and boilers for locomotive, marine,
portable, stationary, road, omnibus, car, wagon, truck, or other purposes
where power is requisite, in which the superheated steam in passing
through the oil gas generator forms a lubricated and combustible gas,

page_text: which is first used as a motive power by its clasticity or expansion,
and after it has so actuated the pistons of the cylinders of power
engines it is consumed in the boiler or boilers to raise steam from
the water and expand the air (if any). forced into the boiler or
superheater.
Under the first division of steam boilers and oil gas apparatuses, to
produce gas for any of the purposes before named, my Invention for
these improvements consists-
Firstly. In forcing of the requisite quantity of air (heated prefered)
by force pump, fan, or other appliance in connection with conveyance
pipes, into the steam boiler or boilers (prefered), superheater, gas
generator, or conveyance pipes, to promote the circulation of the water
in the first and of oil in the third named, also to prevent the formation
of scale in the first, but chiefly to assist the combustion of the gas
either for bright lights, or strong heating or smelting power; this is
claimed in combination with the production of gas by these generators.
Also the option of forcing the requisite quantity of oil direct into the
steam boiler, and thus dispensing with the gas generator.
Secondly. My Invention consists in the conjunction of the two parts,
viz., the scrubbers and driers, into one part; being a vessel placed
vertically, made of iron, clay, or other suitable substance, built in
brickwork, with fire or flame under and around it, the cover of which
vessel is removeable by bolts and nuts, close set; has a false bottom,
perforated, and the said vessel is filled with charcoal, coke, and a part
of lime, or other alkali or metallic substance. The gas from generator
is conveyed by pipes and enters this vessel under the false bottom,
and passing upwards through the foregoing substances, which are in a
state of red heat, the said oil gas is by this process rendered permanent,
dry, and after being cooled is fit for use or storing in the gasometer.
And Thirdly. My Invention consists in the application of this gas
(manufactured and improved, as before described, from similar or
inferior oils, or other liquids or substances) to fire-grates, or stoves,
filled with asbestos, pumicestone, or other metallic substances, to
which the gas is applied underneath, or burned in the terra cotta clay
stoves, cooking apparatuses, or other domestic or commercial uses, and
also to the smelting of iron or other stone in blast furnaces, heating
iron or other metals in furnaces or fires for plates, rods, rails, or

page_text: manufacturing purposes, and for furnaces or retorts for the conversion
of iron into stecl. The steam used at iron and steel works for the oil
gas generators may be generated by the waste gases of furnaces or
fires.
And under the second division of oil gas engines and boilers for any
of the purposes before named my Invention for these improvements
consists―
Firstly. In forcing a requisite portion of air (heated prefered) by
force pump, fan, or other appliance, into the steam boiler (prefered
and claimed in conjuction with these oil gas engines), superheater, gas
generator, or conveyance pipes, to circulate the water in the former
and prevent scale forming on the plates, and in either of them (and
chiefly) to assist the combustion of the gas after it has actuated the
pistons of the cylinders of any power engine. And the application of
this to existing steam engines and boilers of all kinds, converted to the
use of oil from that of coal, coke, wood, or other combustible. Also
in an improved bell-crank valve, to regulate the combustion under
pressure with communicating rod and handle to driver.
Secondly. My Invention consists in a reciprocating axle, by the
bushes moving in a slot in the circular plates of the plumber blocks,
for say twelve inches (more or less), to prevent friction on locomotive,
road, car, omnibus, wagon, or truck engines, or to the axles of any
description of vehicles attached thereto. Also in winding leather on
its edge in strips, on the tyres of driving tramway wheels to prevent
slipping on the rails.
Thirdly. My Invention consists in placing these engines vertically,
fixed to the steam boilers, and the option of dividing them into two,
for use in omnibusses, tramway cars, wagons, trucks, or similar vehicles
for the common roads, or railway purposes, placed vertically at the
sides and actuated from either end of the vehicles, so as to give a clear
passage through these vehicles from end to end.
Fourthly. My Invention consists in the application of the gas
improvers and pipes of fire-clay or metal, fitted on the exhaust gas
pipes in the combustion chambers of the steam boilers, and of branch
starting tubes and fillers to any of the engines for any of the purposes
before specified.

page_text: Fifthly. My Invention consists in the option of forcing direct into
the steam boilers of these oil gas engines of any description the requisite
quantity of oil and air (heated prefered), and thus dispensing with
the gas generator and superheater; this can be carried out at small
cost to existing steam engines of all kinds to be converted from the use
of coal or coke to that of oil.
Sixthly. My Invention consists in the use of these improved oil gas
engines and boilers at fixed stations on the line of route of railways,
tramways, or common roads, for compressing air or raising steam to
supply the receivers in the vehicles, to actuate power engines fixed
therto for any of these purposes.
And Seventhly. My Invention consists in connection with these
oil gas engines, as locomotives on railways, and tramway car and
omnibus engines, in improved conveyance pipes, unions, fittings, and
apparatus for conveying the steam from the boiler or exhaust to and in
the carriages, omnibusses, and cars, in connection therewith, to warm
these vehicles in cold weather; or for this purpose, and that of lighting,
gas from the generators may be conveyed by pipes and unions of
smaller size and burned in these vehicles in stoves and glass globes to
give warmth and light. By the same apparatus I effect ventilation
of these vehicles in hot weather by fresh air from force pump or other
appliance.
