"IMPROVEMENTS IN CONNECTING THE RESERVOIRS OF OIL AND SPIRIT LAMPS,
FLOWER VASES, CENTRE PIECES, AND OTHER ARTICLES TO THEIR PILLARS OR
STANDS, AND IN CONNECTING THE BURNERS OF OIL AND SPIRIT LAMPS TO THEIR
RESERVOIRS."
My Invention consists of the construction and combination of parts, hereinafter
described, for connecting the reservoirs of oil and spirit lamps, flower vases, centre
pieces, and other articles to their pillars or stands, and for connecting the burners
of oil and spirit lamps to their reservoirs.
By my Invention a very simple and efficient connection of the parts to be connected
is effected, and the use of plaster of Paris or other cement is dispensed with.
For convenience of description I will first describe my Invention as applied to
the connection of the reservoir of an oil or spirit lamp to its stand.
On the underside and at the centre of the glass reservoir of the lamp I make a
long peg, the said pog having a square or oval figure in cross section, or the said
peg may have the figure of a cylinder flattened at one or more parts. Near the
lower end of the peg I make an annular groove or deep ring like depression. The
metal socket by which the reservoir is to be directly connected to the lamp pillar
or stand has an internal figure, the counterpart of the external figure of the peg
on the reservoir, so that when the socket is placed upon the peg, the former cannot
rotate upon the latter. The lower end of the metal socket has an external scrow
to take into a corresponding concave screw in the top of the lamp pillar or stand.
When the socket is fitted upon the upper part of the peg of the resorvoir, and in
contact with the underside of the reservoir, the lower end of the screwed part of the
socket is situated immediately above the annular groovo in the peg. In the said
annular groove a strip of lead or other soft metal is placed by bending the strip
around a part or the whole of the groove. The soft metal strip when placed in the
groove constitutes a washer. The said washer is made of a thickness equal to the
combined depth of the groove and the thickness of the screwed edge of the socket, so
that the upper edge of the washer projects in front of or is presented to the lower
screwed edge of the socket.

page_text: A head or expanded part is thus formed at the front of the screw collar, which
prevents the latter being withdrawn from the peg. After the metal socket has
been secured to the peg of the reservoir in the way described, the screw of the
socket is screwed into the lamp pillar or stand in the usual manner. By the
screwing home of the socket the reservoir is connected to the pillar or stand, the
soft metal washer on the peg being enclosed or surrounded by the upper part of
the pillar or stand and held securely in its place on the peg.
A protuberance may be formed on the reservoir or on the peg, and the
protuberance be made to fit into a corresponding recess, notch, or depression in the
socket to prevent the rotation of the said socket; or the parts described may be
reversed with the same effect.
.
In applying my improvements to the connecting of flower vases, centre pieces,
and other like articles to their pillars or stands, I construct and combine the parts,
substantially as described with respect to a lamp reservoir.
In applying my improvements to the connecting of lamp burners to their oil
reservoirs, I make the neck at the summit of the oil reservoir longer than usual, and
in the lengthened neck the groove for receiving the soft metal retaining washer is
made. Upon the said neck a scrow collar or ring is fitted which is prevented
from rotating thereon and is retained in its place in the manner described with
respect to the collar on the peg of the reservoir. The bottom part of the burner is
furnished with an internal screw for screwing upon the external screw of the collar
on the neck, the screwing home of the burner on the neck of the reservoir covering
and holding in its place the soft metal washer in the groove of the neck, as
before described.
