A New or Improved Method of and Means for Automatically Supply-
ing Paraffin or other Oil to Oil Lamps more particularly Intended
for Use in connection with Incubators.
1, GEORGE WALLIN, of 54, Gt. Dover Street, Borough, S.E., Gentleman, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved method of and means for auto-
matically supplying oil, to oil lamps such as are more particularly intended for
use in connection with incubators, although it may be used with other lamps
required to be automatically supplied with oil to allow of their burning for a
considerable period without attention, the object of this invention being to
provide simple and efficient means for the purpose in view.
This invention consists essentially in running the supply pipe into the oil
chamber of the lamp and furnishing it at its inner extremity with a simple
automatically operated valve which shall allow oil to pass through the supply
pipe, which is in connection with a suitable storage tank or reservoir, into the
lamp as it is required for use.
In carrying this invention into practical effect, the inner extremity of the
supply pipe or a screw threaded extension thereof is closed at the end and
furnished with a hole or perforation upon the top side through which the oil is
designed to pass.
The extremity of this pipe is furnished with a vertical arm formed with a
lug or lugs through which a sliding rod passes, furnished at its lower extremity
with a cone shaped plug designed, when the said rod is depressed, to close the
aforesaid hole or perforation and cut off the supply of oil, but which is normally
retained in the raised position by means of a spiral spring or its equivalent.
This sliding valve rod is operated by means of a pivoted arm or lever one
extremity of which bears upon the upper end of the said rod, the other extremity
being furnished with a ball or float resting upon the surface of the oil within the
lamp.
As the quantity of oil within the lamp diminishes, the end of the operating
lever carrying the ball or float falls, the valve operating rod is automatically
raised by the action of the aforesaid spiral spring, and oil enters the lamp, while
upon any predetermined height or level of oil being reached within the lamp,
the operating lever is sufficiently raised to depress the valve operating rod, the
cone shaped plug at the extremity of the aforesaid rod closing the hole or
perforation herein before referred to, and cutting off a further supply of oil.

page_text: A New or Improved Method of and Means for Automatically Supply-
ing Paraffin or other Oil to Oil Lamps more particularly Intended
for Use in connection with Incubators.
I, GEORGE WALLIN, of 54, Gt. Dover Street, Borough, S.E., Gentleman, 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:—
This invention relates to a new or improved method of and means for auto-
matically supplying oil to oil lamps such as are more particularly intended for
use in connection with incubators, although it may be used with other lamps
required to be automatically supplied with oil to allow of their burning for a
considerable period without attention, the object of this invention being to
provide simple and efficient means for the purpose in view.
This invention consists essentially in running the supply pipe into the oil
chamber of the lamp and furnishing it at the inner extremity with a simple
automatically operated valve which shall allow oil to pass through the supply
pipe, which is in connection with a suitable storage tank or reservoir, into the
lamp, as it is required for use.
In carrying this invention into practical effect, the inner extremity of the
supply pipe or a screw threaded extension thereof is closed at the end and
furnished with a hole or perforation upon the top side through which the oil is
designed to pass.
The extremity of this pipe is furnished with a vertical arm formed with a
lug or lugs through which a sliding rod passes, furnished at its lower extremity
with a cone shaped end designed, when the said rod is depressed, to close the
aforesaid hole or perforation and cut off the supply of oil, but which is normally
retained in the raised position by means of a spiral spring or its equivalent.
This sliding valve rod is operated by means of a pivoted arm or lever one
extremity of which bears upon the upper end of the said rod, the other extremity
being furnished with a ball or float resting upon the surface of the oil within the
lamp.
As the quantity of oil within the lamp diminishes, the end of the operating
lever carrying the ball or float falls, the valve operating rod is automatically
raised by the action of the aforesaid spiral spring and oil enters the lamp, while
upon the predetermined height or level of oil being reached within the lamp
the operating lever is sufficiently raised to depress the valve rod, the cone shaped
end of which closes the hole or perforation herein before referred to, and cuts off
a further supply of oil.
In order that this invention may be more fully understood I will now proceed
to describe same with reference to the accompanying drawings in which:-
Fig. 1 is a general sectional view of the oil containing and supply receptacles
with the valve mechanism in elevation.
Fig. 2 is a side elevation of the valve detached and drawn in an enlarged
scale as compared with Fig. 1.
"
According to this invention and in the form shewn in Fig. 1 of the accom-
panying drawings, a represents the lamp reservoir or oil container which is
fitted with a burner of any suitable or well known form, while 6 represents the
oil supply tank. The supply pipe (Figs 1 & 2) is furnished at the top with a
hole or perforation c¹ through which the oil is designed to pass for feeding the
lamp reservoir a, and the extremity of this pipe c which is closed, carries a

page_text: vertical arm furnished with perforated lugs e e through which a sliding rod f
passes, and which is cone shaped at its lower extremity f¹, (Fig. 2), so as to close
the hole or perforation c¹ in the supply pipe c when depressed, but which is
normally retained in the raised position by the action of the spiral spring g
acting between the lower lug e and a screw stop g¹.
The sliding valve rod g is operated by a pivoted arm or lever h, carried by the
forked upper extremity of the vertical arm d, the extremity h¹ of the said
arm or lever resting or bearing upon the upper extremity of the valve rod f
while the other extremity of the said arm or lever h carries a hollow spherical
body or float q (Fig. 1).
The operation is as follows:-
As the quantity of oil in the lamp reservoir a diminishes, the end of the arm or
lever carrying the ball or float g, falls, thereby raising the extremity h¹ out of
contact with the valve rod f which is lifted by the action of the aforesaid spiral
spring g, and in this manner the hole or perforation d in the supply pipe c is
opened, and oil passes from the oil containing tank 6 to the lamp reservoir a.
As the oil passes into the lamp reservoir a, the extremity of the arm or
lever h carrying the ball or float q is gradually raised, the other extremity being
correspondingly depressed so as to bear upon the upper extremity of the
valve rod f which is gradually forced down until, upon a predetermined quantity
of oil having passed into the oil reservoir «, the hole or perforation cl in the
supply pipe c, is completely closed by the cone shaped end f¹ of the sliding
valve rod f, and a further supply of oil is cut off.
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--
1. The new or improved method of and means for automatically supply paraffin
or other oil to oil lamps, more particularly for use in connection with incubators,
consisting in combining an oil supply tank with a lamp reservoir, connecting
the two by a supply pipe and furnishing the supply pipe at the extremity within
the lamp reservoir with an opening or perforation through which the oil passes,
arranging a sliding valve rod above the said hole or perforation, which is raised
or lifted by the action of a suitably arranged spring, and providing a pivoted
arm or lever furnished at one extremity with a Hoat, for depressing the sliding
valve rod for closing the hole or perforation in the supply pipe upon the required
quantity of oil having passed into the lamp reservoir, the whole arranged,
constructed, and operating, substantially as herein described and shewn with
reference to the accompanying drawings, and for the purposes specified.
2. The new or improved method of and means for automatically supplying
paraffin
or other oil to oil lamps, more particularly intended for use in con-
nection with incubators, substantially as herein described and shewn, with
reference to the accompanying drawings and for the purposes specified.
