Improvements in Oil Fired Furnaces for Generating Steam for Water
Raising Apparatus, and for other purposes.
I GEORGE ROSE, Engineer of Eathell Cottage Bishopbriggs near Glasgow do hereby
declare the nature of this invention to be as follows:-
Force pumps as hitherto made have all a seperate Boiler for Raising Steame to work
thein and also an attendent to look after the Boiler I propose therefore to. do away
with the attendent after the pump or apparatus has once been started as well as
making it more simple than and easier to work also the cost will be much cheaper.
In working out my invention I mount a cassing having two or more wheels the
cassing would be lined with Brick or any suiatable material so as to conserve the heate
inside of same, inside of the brick work I place a steame generator of tubular construction
the ends of the water passages would be kept outside and there would be cleaning
screws or plugs on the ends projecting for the purpose of Removing any deposite from
the Water A drum is connected to the tubuler arrangement for the purpose of Holding
Steame and also to assist in the Making of steame water would be supplyed in the
ordinarey manner or the genearator would be conected to a gravitation suply The
fuile to be used is oil preferably, though Coale or Coake may be used to Raise Steame
when either of these are used a fire box would be attached, When oil is used an oil
Spray would be used Mixed with Steame or air under Compression The pumps would
be Mounted on the Top of the Caseing and all Conections for working pump would be
made to the Drum and So as to allow the Pump to be Intyrley Independent of aney
outside water Suply I fit a Close Tank on the underside of the Casing A hand pump
would be fitted into same for the purpose of Creating a presure to begin with. After
the pump has been once Started it would keep up its own presure in the Water Tank
by a small auxilary pump, a valve for allowing excess of presure to escape would be
fitted on the Water Tank and by this Means a uniform presure Can be Maintained
in Tanks.
Under a Modification I fit an Anular Chamber inside of a cassing Suiatable handles
for lifting it about would be fixed to same the one end of Geneareator has a Coile wound
Round it the water pases through this to Generator and is heated by the action of
the hot Gases it at the same time keeps the end of Generator Cool and so prevents
Generator from becoming over heated instead of a force pump being fited in this Case
I fit what I Call A Water Raiser or Injector to the Generator, the heate would be
suplyed in either of the ways allready mentioned and by letting a jet of Steame escape
into the Chimirey a Much More Intense heate may be got, Insted of using a steame or
air oil spray I would fit an oil gas or oil vapour Genearator in side of one end of the flame
passage in Steame Genearator the Heate from the flame would radiate on to same and
maintain sufeiicent heate to vapourize the oil to be used for Raising Steam I may
also place the vapourizer so as to be heated by the waste gases. This form of
Water Raiser can be made so small that aney one can carrey it about. A Water
Tank would be raised above the Raiser and be used as a storage Tank water
would be drawen. from it as required When water is required to be forced a greate

page_text: height I would lead a second pipe from where the Water is stored back to the
genearator instead of having a Separate Presure Tank the water presure for Raising
Steame would be had from this second pipe instead of using two pipes a branch
from the Delivery pipe would serve the purpose the presure inside this pipe
would give the necessery water presure for Raising Steame in the Genearator,
Instead of using the Diferant Methods aforementioned for giving intense heates
in furnaces I would use an oil Well this well would be fitted with a float valve
for keeping the oil at a proper leavel the oil would simpley be set fire to The oil
would be suplyed to the well from a separate oil Tank The well would be made
or fixed so that the Deposite left by the burning oil Could be Removed The oil
Well would be fixed preferably on the underside of the brick lined Cassing or furnaces
and air to suport cumbustion would prefrably Come in between the Bricks and the
Top of the well, so as to assist Cumbustion I place a steame or air Jet in the funnel
and also another at the Point where the flame from oil Well enters the furnace the
Induced Curent of air Caused by these jets gives almost a smokless flame without
them the oil will not burn properley When a streame of water is wanted to be throwen
a greate height I Mount a Small Tank on the Injector the Water is forced into it The
Imprisoned air would act as a Cushion the Water would be led by a hosepipe
prefrably from the bottom of the aforementioned Tank This apparatus would
be invaluable for Irigating or for puting out fires owing to its lightness and
portibility.
When Intense heates is wanted in fire brick lined furnaces I put a small generator
in the funnel and Make steame to Create a partial vaucum to give Draught The gases
from the oil Well would be drawn through the Coumbustion Box or gas Chamber of
furnace A jet of steame might also be used to blow in amongest the ascending gases A
Most Intense Heate can be got in this way Instead of Making Steame I may use Steame
from a seperate Boiler to get this Intense heate.
When the Apparatus is used for heating by the use of Steame onley I would allow the
Steame to escape into the emptey pipes the Condensed Steame would would be caught
in a pan or it may Trickle into a Drain Also when a long uniform heate is wanted I
may lengthen the oil well as I may employ Two or More Gas Apparatuses as afore
Mentioned and so as to allow a full suply of air for the furnaces perforated Bricks
are placed in suitable parts of the furnaces or Gas Chambers.

Improvements in Oil Fired Furnaces for Generating Steam for Water
Raising Apparatus, and for other purposes.
I GEORGE ROSE Engineer of Ethell Cottage Bishopbriggs near Glasgow, do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
Force pumps as hitherto made have all had to be supplied with steam boilers and
also an attendant, to work same. In Working out my Invention I do away with the
attendant, simplify the construction as well as cheapen the cost and manufacture
of same.
And in order that my present Invention may be properly understood I have
annexed the accompanying Drawings.
As shewn on Fig. 1 Sheet 1 of the Drawings, in working out my Invention I
mount a force pump 7 on a casing 8 lined with a fire-brick or other suitable heat
resisting material mounted on Two or more wheels 9 by which it can be easily

page_text: wheeled about. Inside the fire-brick lining I fit a steam drum 10 of longitudinal
cylindrical form preferably having tubes 11 projecting from the bottom thereof
Suitable cleaning plugs or other arrangements would be made on the ends of the tubes 11
for removing any deposit that may take place by the evaporation of the water. The
water may be supplied by pipe 12 from the ordinary gravitation supply, or from a
tank 13 having a pump 14 for purpose of creating a pressure inside of same so as to
force the water into the generator 10. The heat would be supplied by any suitable
oil spray burner 15 working with a jet of steam by pipe 16 from generator; oil being
led by pipe 17 from tank 18. The ends of the tubes 11 are preferably kept outside
the casing so as to be kept away from the intense heat. When once the force
pump 7 is set going, which is fed by pipe 19 with steam, which takes about
10 minutes no more attention is needed. The pressure in the tank 13 may be kept
up by the hand-pump 14 or a small auxiliary pump (not shewn) working in connection
with large one. Any surplus pressure created in water tank 13 being allowed to
escape by valve 20 and so keep a uniform pressure therein.
Under a modification as shewn at Fig. 2 I fit a steam generator 10 into the
casing 8 lined with brick and having suitable carrying arrangements 21 instead
of wheels 9. The generator 10 is preferably of an annular shape On the end of
the generator 10 I wind a coil of piping 22 through which the water is allowed
to pass before entering the generator. By this arrangement the water is not
only heated but the end of the generator 10 is kept from becoming overheated
by the gases from the burner. Instead of a force pump being mounted for
water raising I fit to the generator an injector or water raiser 24. Fig. 3*
supplied with steam from generator 10 by pipe 27 The heat supplied would be
in the same way as already described and to cause a draught in chimney 28 I
would fit a small steam jet nozzle for steam to issue out of.
Instead of using a steam oil-spray burner I would fit an oil-gas or vapour
generating burner 25 inside of one end of flame passage at 55 Fig. 2 the heat
from the oil flame would radiate on to same to enable the oil to be gasified or
vapoured; or the said oil-vapour generator may be fitted outside of generator but
inside of casing so as to receive sufficient heat from the waste gases for the perfect
vapouriring of the oil, the oil gas made therein would be led to bottom of generator
and burned as already described for the generating of steam. This form of water
raiser can be made very small and is intended for household purposes. The
water raised by Apparatus would flow into a storage tank, and so as to keep the
generator always supplied with water for making stean a pipe would be led from
bottom of storage tank (not shewn) and connected to generator. This would make
apparatus entirely self-contained and automatic in its action.
Instead of using the burners aforesaid I fit an oil well or pan 29 Fig. 4 on the
underside of steam generator which may be surrounded with a light casing half-way
up (not shewn). On top of steam generator a coil of pipe would be placed so as to
heat the water by the waste gases passing away The pan 29 would be placed so as to
allow the proper proportion of air to enter flame passage along with gases from the oil.
Otherwise the oil cant be properly burnt. The oil would be led to the pan by
suitable connections.
As shewn at Fig. 2 Sheet 2. I apply the same principle to a self-contained crucible
furnace In this case the oil well or pan 29 would be provided with a ball-valve
arrangement 30 for regulating supply of oil to same This oil-well or pan would
be partially covered over on top and have a round or square hole for the gases to pass
through into the furnace; the gases from the oil in this pan would not be allowed to
ignite, otherwise the pan would be destroyed. The proper amount of air would be
allowed to enter in along with the oil-gases entering into furnace. So as to cut off all
communication suddenly of the gases I fit a damper 50 to go between the top of oil
pan and bottom of furnace.
Fig. 1, Sheet 2 illustrates a portable self contained furnace. In this case a shallow
pan 59 is fitted or hinged to bottom of furnace. In this case the oil is allowed to
ignite in the pan and the air is allowed to impinge on to the bottom of inside of pan 59

page_text: and mixes freely with the flame in the pan made from the oil. This form of pan
possesses advantages over oil-well 29 as almost all the deposit from the oils is carried
away by the action of the fierce flame which takes place inside of it, and is intended
to be used for short heats only. The air to support combustion would be drawn in by
the action of forced draught caused by a steam jet placed in the funnel or any
suitable part of furnace as at point 57.
When long furnaces are to be heated I fit a combustion chamber 61 similar to those
before already described this apparatus not being shown. The funnel to carry off
the bye-product would be preferably in the centre; The air to support combustion
may be leated to whatever temperature is desirable before being allowed to come in
contact with the oil gases. By doing so a greater heat can thus be attained.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st. A steam generator with heating coil on the top in combination with an oil
well or pan for the purpose of generating heat from the oil the air to support
combustion entering in between the bottom of generator and top of said pan
or oil-well.
2. Self-contained Portable furnaces with oil-well or pan burners substantially as
described and shewn.
3. In combination with Furnaces or Steam Boilers, an apparatus working with
oil for the generating of heat having a pan or oil-well burners substantially as
described and shown.
4. In combination with furnaces, steam generators or boilers working with oil
as before described and shewn, a steam jet for creating a forced draught or suction
in the funnel for the better combustion of the crude oils.
5. The general combination and arrangement of parts of steam generators,
boilers or furnaces, as and for the purposes set forth and shewn.
Dated this 1st day of June 1897.
