Year: 1878

page_text: LETTERS PATENT to William Edward Teale, of Fern Bank, Worsley, in the
County of Lancaster, Lamp Manufacturer, for the Invention of "CERTAIN
IMPROVEMENTS IN LAMPS FOR DOMESTIC AND OTHER PURPOSES."
Sealed the 27th May 1879, and dated the 30th November 1878.
PROVISIONAL SPECIFICATION left by the said William Edward Teale at
the Office of the Commissioners of Patents on the 30th November 1878.
WILLIAM EDWARD TEALE, of Fern Bank, Worsley, in the County of Lancaster,
Lamp Manufacturer. "CERTAIN IMPROVEMENTS IN LAMPS FOR DOMESTIC AND
OTHER PURPOSES."
My Invention has for its object to make hand lamps more serviceable by
preventing the possibility of accidents by tampering or by carelessness, and to afford
a superior light. In carrying my Invention into effect I make a circular metallic
lamp cell in the inside of which I place pieces of ordinary sponge; on the upper
surface of the said cell I fix a wick tube carrying on its outer surface an ordinary
screw thread which takes into a similar thread within an extinguisher of circular
form, which said extinguisher carries a screw thread taking into a metal cap or
cover which covers the lamp cell; I fix a stop pin on the extinguisher in a con-
venient position to enable it to come in contact with a moveable bolt fixed in the
side of the metallic cap or cover. On the upper surface of the said cap I fix a series
of stout wire pillars carrying a ring or disc to which I fix a wire gauze. Between
the space of the lamp cap or cover and the metallic ring or disc I place a closely
fitting glass tube. In putting my Invention into effect I place a wick within the
wick tube extending the same within the metallic cell; I then fill the cell with
naphtha or petroleum or other inflammable oil; I then screw the extinguisher down
upon the wick tube. I then light the wick, and by means of the screw thread

page_text: carried by the exterior of the extinguisher I screw the same into the cap or cover,
bringing the said cap or cover completely over the metallic cell. The various parts
being thus in position I push forward the bolt towards the extinguisher, so that it
may come in contact with the stop pin carried thereon, and so prevent its being
unscrewed. Any attempt to unscrew the lamp brings the wick tube down within
the extinguisher and so puts out the light. To the moveable bolt I fix a spring
which, when pushed forward into position, is let go and prevents the bolt being
released from the outside of the cap or cover. For the more convenient use and
carrying about of my improved lamp I fix to the stout wire pillars a handle. On
the upper surface of the cap or cover I cut a series of grooves to admit air to
support combustion.

WILLIAM EDWARD TEALE, of Fern Bank, Worsley, in the County of Lancaster,
Lamp Manufacturer. "CERTAIN IMPROVEMENTS IN LAMPS FOR DOMESTIC AND OTHER
PURPOSES."
My Invention has for its object to make hand lamps more serviceable by
preventing the possibility of accident by tampering or by carelessness, & to afford
a superior light.
In carrying my Invention into effect I make a circular metallic lamp cell, in the
inside of which I place pieces of ordinary sponge.
On the upper part of the said cell I fix a wick tube carrying on its outer surface
an ordinary screw thread whch takes into a similar thread within an extinguisher
of circular form, which said extinguisher carries a screw thread which takes into a
metal cap or cover which covers the lamp cell.
•
I fix a stop pin on the extinguisher in a convenient position to enable it to come
in contact with a moveable bolt fixed in the side of the metallic cap or cover. On
the upper surface of the said cap I fix a series of stout wire pillars carrying a ring or
dise to which I fix a wire gauze. In the space between the lamp cap or cover and
the metallic ring or disc I place a closely fitting glass tube.
In putting my Invention into effect I place a wick within the wick tube
extending the same within the metallic cell. I then fill the cell with suitable
inflammable oil. I then screw the extinguisher down upon the wick tube. I then
light the wick, & by means of the screw thread carried by the exterior of the
extinguisher I screw the same into the cap or cover, bringing the said cap or cover
completely over the metallic cell.
The various parts being thus in position I push forward the bolt towards the
extinguisher, so that it may come in contact with the stop pin carried thereon, &
so prevent its being unscrewed; any attempt to unscrew the lamp brings the wick
down within the extinguisher, and so puts out the light.
To the moveable bolt I fix a spring which when pushed forward into position is
let go and prevents the bolt being returned from the outside of the cap or cover.
For the more convenient use and carrying about my improved lamp I fix to the
stout wire pillars a handle.
On the upper surface of the cap or cover I cut a series of grooves to admit air
to support combustion.
Hereafter I will more fully describe & illustrate the particulars of my said
Invention.
In order that my Invention may be clearly understood I annex hereto a Sheet
of Drawings, marked with figs. & letters of reference.
Figure 1 is an elevation.
Figure 2, a plan.
Figure 3, a sectional elevation.
Figure 4, a section through y, z.
Fig. 5, a section with the metallic cell & wick tube removed.
Fig. 6, a side view of the metallic cell & wick tube.
Fig. 7 is a plan of a moveable bolt with a semicircular end H, H.
Fig. 8, a side view of Fig. 7, showing a spring T.
A is a metallic lamp cell; B, a cap or cover for the lamp; C, a wick tube
rising from the centre of the metallic cap or cover carrying a screw thread; D is a
hollow metal cone partly cut away at its base to admit air immediately below the.
flame of the lamp, and to cause more perfect combustion, the said cone being
suitably adjusted for that purpose; E is an extinguishing tube carrying a screw
thread at S&a sunk collar at its lower extremity; G is a moveable bolt fixed in
the side of the metallic cover B & carrying a semicircular collar at H, H; i is a

page_text: button shaped termination to the bolt G for the better manipulation of the same by
the fingers; J is a metal case fixed in the side of the cover B in which the bolt Ğ
moves; K is a circular glass cylinder for protecting the flame; Q are stout wire
pillars terminating in a metallic ring or disc; P is a moveable disc for closing the
orifice of the cell A after filling the same with oil; L, L, are two metal brackets
fixed on the stout wire pillars Q carrying a handle M for the more convenient
moving of the lamp from place to place. In order to facilitate the cleaning of the
glass cylinder K I unscrew one of the stout wire pillars and remove the glass
cylinder for that purpose. F is a stop pin fixed in the sunk collar of the extinguish-
ing tube E; N is a chimney fixed upon a wire gauze u supported by the disc P.
Without & surrounding the said chimney N I place a wire gauze when I require
to use my improved lamp for mining purposes.
The various parts being thus described, in order to put my Invention into use I
place a lamp wick within the wick tube C extending the same within the lamp
cell A; I then fill the cell with suitable oil & screw down the extinguishing tube E
over the wick tube C and light the lamp; I then screw the cell A & extinguishing
tube into the cap or cover B, thus effectually closing the lamp, and when in this
position I push forward the bolt G, the semicircular point thereof taking into
the sunk collar of the extinguishing tube E, when the spring I is let go projecting
against the metal case J (as shown at Fig. 3), any attempt to unscrew the lamp
brings the stop pin F in contact with the bolt G, the effect being the wick tube Ċ
is drawn within the extinguishing tube E & thus puts out the light. In order to
re-light the lamp I depress the spring T and push back the bolt G from the stop
pin F, and unscrew the extinguisher from its position & again light the lamp and
close it as before described.
Having now fully described & ascertained the nature of my said Invention, & in
what manner the same may be carried into effect, I would observe in conclusion that
what I claim as novel & original, & as secured to me by the aforesaid in part recited
Letters Patent is,―
Firstly. The arrangement of the various parts of mechanism in the manner & for
the purpose herein described & illustrated.
Secondly. The application & use of a hollow metal cone for the purpose of
increasing combustion in lamps, as herein described and illustrated.
In witness whereof, I, the said William Edward Teale, have hereunto set my
hand & seal, this Twenty eighth day of May, in the year of our Lord One
thousand eight hundred & seventy nine.
