of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS IN
LAMPS." A communication from abroad by George Chappel, of Brooklyn, New
York, United States of America, Manufacturer.
The object of this Invention is to simplify and cheapen the construction of lamps,
also to provide a lamp that can be conveniently filled without removing the cap of
the same for the purpose.
The Invention consists of a lamp provided with a collar having a hemispherical
top, with an opening therein, in combination with a rotating or partially rotating
dome-shaped cup provided with an opening corresponding with the opening in the
dome-shaped top of the collar, the wick tube, which is provided with a series of
arms at its upper end being made in one piece with or otherwise attached to said
tube, which is secured to the dome-shaped top of the lamp collar at its centre, and
serves as a pivot around which the cap rotates in order to open or close the lamp,
the cap being permanently secured to the lamp. The improvements may be con-
structed of metal.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS IN
LAMPS." A communication from abroad by George Chappel, of Brooklyn, New
York, United States of America.
This Invention relates to certain improvements in lamps, its object being to
simplify and cheapen the construction of the same, and provide a lamp than can be
conveniently filled without removing the cap of the same for the purpose.
The Invention consists of a lamp provided with a collar having a hemispherical
top, with an opening therein, in combination with a rotating or partially rotating
dome-shaped cap provided with an opening corresponding with the opening in the
dome-shaped top of the collar; the wick tube, which is provided with a series of
arms at its upper end made in one piece with or otherwise attached to the said tube,
and which is secured to the dome-shaped top of the lamp collar at its centre, and
serves as a pivot around which the cap rotates in order to open or close the lamp,
the cap being permanently secured to the lamp.
In the Drawing Figure 1 represents a side view of the improved lamp, showing
the cap closed; Fig. 2 is a similar view, showing the cap open; Fig. 3 is a top view
of the lamp, showing the cap open.
Similar letters indicate corresponding parts.
The letter A represents the body of the lamp, and B a collar secured permanently
to the neck thereof. Said collar is provided with a dome-shape top, which has an
opening b at one side, and to the centre of which is secured the wick tube C, the
latter being provided with three or more arms c, formed of the same piece of metal,
and bent into proper shape to support the chimney or shade D.
If desired the arms c may be formed on a separate tube, which slips over the wick
tube.
The letter E represents a rotating or semi-rotating cap similar in configuration to
the dome-shaped top of the collar, and provided with a corresponding opening b.
Said cap is secured over the dome-shaped top of the collar, an aperture being made
at its centre, trough which the wick tube C passes. Said wick tube is provided
with a shoulder e, just above the cap, which serves to confine said cap on the dome-
shaped top of the collar, the cap being capable of rotating or partly rotating around
the wick tube. In the present instance the cap is represented as. having only a
partial rotation, its motion being limited in both directions by means of lugs d
stamped up at each side of the opening in the top of the lamp collar, which enters
into the recesses g in the rotating cap when the same is fully opened or closed.
The lower edge of the cap is milled or roughened to facilitate turning.
I claim,-
1. The wick tube C having arms c for supporting the chimney or globe in com-
bination with the collar B, having the opening b, and provided with a moveable cap,
said cap having an axis on the wick tube C, substantially as described.
2. In combination with collar of the lamp, provided with a dome-shaped top,
having an opening therein, the rotating cap secured on the top of the collar, and the
wick tube passing through said cap, and secured to the dome-shaped top; said tube
having supporting arms formed in one piece therewith, and a shoulder for confining
the cap in place, substantially as herein set forth.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Third day of December, in the year of our Lord One
thousand eight hundred and seventy-seven.
