IMPROVEMENTS IN LAMPS AND THEIR BURNERS
Year: 1882

page_text: LETTERS PATENT to Henry Salsbury of 125 and 126 Long Acre in the County
of Middlesex, Lamp Manufacturer for an Invention of IMPROVEMENTS IN
LAMPS AND THEIR BURNERS
PROVISIONAL SPECIFICATION left by the said Henry Salsbury at the
Office of the Commissioners of Patents on the 22nd November 1882.
HENRY SALSBURY of 125 and 126 Long Acre in the County of Middlesex,
Lamp Manufacturer IMPROVEMENTS IN LAMPS AND THEIR BURNERS
This Invention relates to certain detail improvements in lamps and their
burners.
The first part refers to the oil well and its burner or wick holder hinged thereto
or to a collar thereon that it may be turned back to permit of oil being poured into
the well through the opening which the base of the burner fits by inclined surfaces
on its lower part which corresponds with an inclined faced collar or ferrule fitted
in or to the oil well itself. The collar or ferrule has an aperture to allow for
expansion and also to permit of the well being filled to that level. By this portion
of my Invention the usual filling hole and its threaded socket and threaded cap
are dispensed with.
The hinged burner can be secured in position by any form of clip spring but I
prefer to attach a light metal flat spring to the lower part of the oil well and
within a shield that the upper part which is exposed and dished and the edges
undercut may act upon the taper rim of the burner and hold it firmly.
The Second part of my Invention has reference to certain means of holding the
star wheels securely and thereby preventing the wick dropping during the
travelling motion of a vehicle to which such may be fitted. For this purpose I fit
a shield over the star wheels and cause it to bear for about one half of the
circumference by a loop spring piece which I force in between the shield and the
inner surface of the taper rim or of the top cap and I fit them in position by
the lower cap.

The next part of my Invention relates to fitting the reflector on a hinged flap at
the back of the lamp body so that the flap can on being lifted expose the reflector
to enable it to be cleaned. The opening is sufficiently large to enable the wick to
be lighted without the lamp, say a Hub lamp being removed from the machine.
When the flap is closed it can be fastened by a sliding or other bolt.
According to the next part of my Invention I fit dioptric or other shaped lenses
or prisms in the sides of lamps with certain parts of the lenses or prisms projecting
that rays of light of the same or of different colours may be refracted to the back
of say a vehicle. By this means I dispense with the usual coloured glass in the
back of the lamp and obtain increased brilliancy with a much greater spread of ]
light than is possible by the present methods.

HENRY SALSBURY of 125 and 126 Long Acre in the county of Middlesex
Lamp Manufacturer IMPROVEMENTS IN LAMPS AND THEIR BURNERS
This invention relates to certain detail improvements in lamps and their
burners as shown in the annexed drawings.
The first part refers to the oil well A and its burner or wickholder B hinged
thereto or to a collar thereon that it may be turned back to permit of oil being
poured into the well through the opening C which the base of the burner fits by
inclined surfaces D on its lower part which corresponds with an incline faced collar
or ferrule E fitted in or to the oil well A as shown at Figures 1 and 2 of the
drawings annexed. The collar or ferrule E has an aperture F to allow for
expansion and also to permit of the well A being filled to that level also for
emptying. By this portion of my invention the usual filling hole and its threaded
socket and threaded cap are dispensed with.
The hinged burner B can be secured in position by any form of clip spring but
I prefer to attach a light metal flat spring G to the lower part of the oil well A and
within a shield H that the upper part which is exposed and dished and the edges
under cut may act upon the tapered rim of the burner B and hold it firmly as
shown at Figure 3.
The second part of my invention has reference to certain means of holding the star
wheels I securely and thereby preventing the wick dropping during the travelling
motion of a vehicle to which such may be fitted. For this purpose I fit a shield
over the star wheels I and cause it to bear for about one half of the circumference
by a spiral spring K which I force in between the shield J and the inner surface
of the taper drum of the top cap B and I fit them in position by the lower cap D.
Figure 4 shows a modified method of fitting the star wheel shield J and
spring K. In this arrangement I form the shield J in a piece with a plate a by
arms b b which plate a serves for the abutment of the spring K whose opposite end
would rest against the wickholder and so pull the shield J into contact with the
star wheel I
The next part of my invention relates to fitting the reflector on a hinged flap M
at the back of the lamp body N so that the flap M can on being lifted expose the
reflector and enable it to be cleaned. The opening is sufficiently large to enable
the wick to be lighted without the lamp being removed from the machine.
When the flap is closed it can be fastened by a sliding or other bolt P.
I have shown my hinged flap and reflector to a hub lamp of a bicycle or
tricycle but it can be arranged to any lamp in which the reflector is required.
According to the next part of my invention I fit dioptric or other shaped lenses
or prisms in the sides R of lamps with certain parts S of the lenses or prisms
projecting that rays of light of the same or of different colours may be refracted
to the back of, say, a vehicle. By this means I dispense with the usual coloured
glass in the back of the lamp and obtain increased brilliancy with a much greater
spread of light than is possible by the present methods
Having now described the nature of my said invention and in what manner
the same is to be performed I declare that I claim
First Hingeing a cupped and tapered-base-wick-holder to an oil well of a lamp to
enable the wick holder to be thrown up for filling purposes as set forth and
as shown in the annexed drawings

page_text: Secondly I claim. The spring on the body of the oil well to nip the wick holder
in position as set forth and as shown in the annexed drawings.
Thirdly I claim Fitting a half or segmental band within the chamber of a wick
holder to impinge against the teeth of the star wheel by the pressure of a
spring as and for the purposes described and substantially as shown at
Figures 3 and 4 of the annexed drawings
Fourthly I claim The employment of prisms as part of side glasses of lamps to
refract portions of light to the rear of the machine as described and
substantially as shown at Q. S Figure 5 of the annexed drawings.
In witness whereof I the said Henry Salsbury have hereunto set my hand
and seal this twenty second day of May One thousand eight hundred and
eighty three
HENRY SALSBURY. (L.S.)
