JAMES FREDERICK HOYNE, of No. 7, Water Lane, in the City of London,
Gentleman. "IMPROVEMENTS IN LAMPS FOR BURNING LIGHT OILS." A com-
munication from abroad by Robert Hitchcock, John Morton Sigourney, and William
Van Vranken Rosa, all of Watertown, County Jefferson, State of New York, United
States of America.
This Invention relates to lamps intended more especially to burn what is called
or known as "light oils," and is an improvement on the Patents granted to John
Henry Johnson, dated 3rd October 1873, No. 3212. "For Improvements in Lamps
for Burning Heavy Oils," being a communication from the said Robert Hitchcock
and others, and to the Patent of the 12th December 1874, No. 4283, granted to
John Henry Johnson, "For Improvements in Lamps, Parts of which Improvements
are Applicable to Spring or Clock-work Movements generally," being a communi-
cation from abroad by the said Robert Hitchcock and others. For the purposes of
the present Provisional Specification I refer to Fig. 1 on the Drawing attached
to the Specification of 1873, and to Fig. 2 in_the_Drawing-attached-to-the
Specification-of-1874.
By my present improvement I retain the position of the vase holding the oil
above the fan, as shewn in Figure 1 in the Specification of 1873, and the spring or
clockwork movement to work the fan, as shewn in Figs. 1 and 2 in the Specification
of 1874, but I dispense with the pump and all the apparatus actuating the same;
so that my present Invention is a combination of the aforesaid two Inventions, so
that I am enabled to use light oils without the use or application of the pump.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Frederick Hoyne in the Great Seal Patent Office on the 14th
September 1880.
JAMES FREDERICK HOYNE, of 7, Water Lane, in the City of London, Gentleman.
"IMPROVEMENTS IN LAMPS FOR BURNING LIGHT OILS."
This Invention is for the purpose of supplying a continuous current of air to the
flame of lamps suitable for burning "light oils," so as to secure a more perfect
combustion, thus producing a brighter and steadier light, freedom from smoke and
smell, and obviating the necessity of a chimney.
The Invention is an improvement on the Patents granted to John Henry Johnson,
dated 3rd October 1873, and Nod. 3212, for "Improvements in Lamps for Burning
Heavy Oils," being a communication from Robert Hitchcock and others, and to the
Patent of the 12th December 1874, No. 4283, granted to John Henry Johnson, for
Improvements in Lamps, Parts of which Improvements are Applicable to Spring
or Clockwork Movements generally," being a communication from abroad from the
said Robert Hitchcock and others.
"
To accomplish this I use the following means:-Firstly, a fan driven by suitable
mechanism to cause a current of air; secondly, passages or ducts through which
the current of air is carried to the flame; thirdly, either one or more domes or caps
having an aperture or apertures for the passage of the flame, and so constructed as
to allow the current of air to pass through both and to impinge on the flame; and,
fourthly, the wind regulator or brake hereinafter described.
Figure 1 of the Drawing hereto represents a vertical section of the lamp con-
structed in accordance with this Invention; Figure 2 is a perspective Drawing of
the case or jacket containing the fan, with its clockwork motor and key or winder.
C, Figure I., is the case of the lamp, which is made of any suitable size, shape, or
material. It is open at the base, which is perforated, as shewn in the Drawing, to
allow a passage for air. The part of the case can be removed, being fitted in
any suitable manner into the swell of the case at 0³.
B, Figure I., is the oil reservoir attached to the part of the case C¹, which is of
any suitable size and shape to fit the lamp, but so as to allow sufficient space
between it and the case for the free passage of air. To the reservoir "B" is fixed
an ordinary gallery, and to the gallery is attached the dome or cap "A," with an
aperture for the flame.
To the reservoir is attached the ordinary apparatus for holding the wick, with
rack work for adjusting the same, worked by the thumbscrew A¹.
In the waist of the case C is fitted a tube P, into which the head of a jacket or
case L (which contains a fan with any suitable clockwork motor or driving gear)
projects, so as to carry the current of air into the cavity between the case and the
reservoir.
The case or jacket L, Fig. I., containing the clockwork, is of such a size as to
allow space for the passage of air between it and the case C, and is attached thereto
by lugs X, X. The arbor of the spring working the clockwork projects from the
case L into the base of the case C, to which is attached the key or winder N. Y is
a catch for stopping the clockwork when neceessary. To the top or nearest side to
the case L of the key or winder is attached a disc or flange S, which is placed at a
suitable distance from the base of the passage Q, with the object of preventing a
too great rush of air into the passage Q. There is also a flange or ring R attached
to the inner part of the case C, and projecting between the base of the passage Q
and the flange S and towards the centre of the lamp, and of such a depth as to
overlap the flange S; thus by the combination of the disc S and ring R forming a
zigzag passage for the entrance of the air into the passage Q, the object being to
form a
"wind brake" regulator or check to any sudden rush of air caused by the
lamp being carried about.

page_text: Figure 2 is a Drawing in perspective. I represents the case containing the fan,
with any suitable clockwork driving gear; N is the key and S the flange or disc
hereinbefore described. The part E which supports the fan is cut away, as shown
at H, so as to allow the air to be drawn through by the fan; I is the fan, which
works horizontally, and is attached to the clockwork by a rod.
When the fan is set in motion the air enters at the perforations at the base of
the case C, passing between the flange S and the ring R into the passage through
the apertures shewn at H, Fig. 2, thence forced by the fan into the passage P, then
into the space between the case C and the reservoir B through the dome A on to
the flame.
Having now described the nature of my Invention I do not claim the particular
form of lamp or the fan and apparatus actuating the same, nor the several parts of
which the whole is composed, but what I claim is, the method of causing a current
of air to impinge on the flame of the lamp so as to obviate the necessity of using a
chimney, by means of a combination of a fan and air ducts, together with the
arrangement for regulating the current of air, all substantially as described in this
Specification and the Drawings accompanying it.
In witness whereof, I, the said James Frederick Hoyne, have hereunto set
my hand and seal, this Thirteenth day of September, One thousand eight
hundred and eighty.
JAMES FREDERICK HOYNE. (LS.)
