PROVISIONAL SPECIFICATION.
Improvements in Means for Stopping the Flow of Oil or other
Liquid from Lamp or other Supply Vessels.
I, SAMUEL NOTON, of 124, Ashton Road, Oldham, in the County of Lancaster,
Ironmonger, do hereby declare the nature of this invention to be as follows:—
This invention relates to improvements in means for stopping the flow of oil or
other liquid from lamp or other supply vessels when refilling the same and has for
its object to dispense with the plug or tap usually employed for the said purpose
and the necessity of packing or grinding of the same and prevent the leakage
heretofore experienced especially in highly searching oils or other liquids.
To this end my improvements consist in the use of an internally applied disc
or other suitable valve operated from the outside of the oil or other liquid supply
vessel.
According to one form of my invention I furnish or form the outlet of the supply
vessel with a short tube projecting outwardly the end of which serves as a valve
seating and the exterior of which is threaded, to permit of screwing the supply vessel
into a socket or supply pipe. On the said valve seating is arranged to operate a
disc or other suitable valve formed on or furnished with a rod or chain passing
through the oil or other liquid supply vessel. The outer end of the said valve rod
or chain is formed or furnished with a mut screwed onto an externally threaded tube
projecting from the top of the oil or other liquid vessel and adapted to screw the
disc or other suitable valve against or away from its seating, thus stopping the flow
of oil or other liquid from the supply vessel when filling the same or vice versa. The
said supply vessel by means of the threaded tube at its outlet is screwed into a
socket or pipe which causes the valve to be positioned internally and thus prevents
all leakage.
According to another form of my invention the said disce or other suitable valve
may be employed separately from the rod or chain operating the same. This I effect
by placing the said disc or other suitable valve upon a spring in the aforesaid socket
or supply pipe which spring presses the said disc or other suitable valve against
its seating from which it is removed by simply screwing down the aforesaid rod.
In this case as well as in the former the valve rod or chain may be raised or lowered
by means of a lever in lieu of by a mut.

COMPLETE SPECIFICATION.
Improvements in Means for Stopping the Flow of Oil or other
Liquid from Lamp or other Supply Vessels.
I, SAMUEL NOTON, of 124, Ashton Road, Oldham, in the County of Lancaster,
Ironmonger, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :--
This invention relates to improvements in means for stopping the flow of oil or
other liquid from lamp or other supply vessels when refilling the same and has
for its object to dispense with the plug or tap usually employed for the said purpose
and the necessity of packing or grinding of the same and prevent the leakage
heretofore experienced especially in highly searching oils or other liquids.

page_text: To this end my improvements consist in the use of an internally applied disc
or other suitable valve operated from the outside of the oil or other liquid supply
vessel.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a longitudinal section of an oil supply vessel for a lamp fitted with my
improvements. Figs. 2, 5, 7 & 8, are longitudinal sections of each end, Figs. 3 & 4
of the bottom end and Figs. 6 & 9 of the top end of the oil supply vessel showing
various modifications of the said valve and the means for operating the same.
Figs. 10 & 11 are side views of the oil supply vessel in connection with an outdoor
and indoor lamp respectively.
According to one form of my invention and referring to Fig. 1, 1 furnish or form
the outlet end a of the supply vessel b with a short tube c with or without a flange,
projecting outwardly, the lower end of which serves as a valve seating d and the
interior or exterior of which is threaded, to permit of screwing the supply vessel b
into a socket or supply pipe e. On the valve seating d is arranged to operate a disc
or other suitable valve formed on or furnished with a rod g, or chain, see Fig. 5,
passing through the oil or other liquid supply vessel. The upper end of the said
valve rod or chain g is formed or furnished with a mut screwed onto an externally
threaded short tube with or without a flange or with a plug screwed into a nut i
soldered to the top of the oil or other liquid vessel band adapted to screw the disc
or other suitable valve against or away from its seating d, thus stopping the flow
of oil or other liquid from the supply vessel when refilling the same or vice versa.
The supply vessel by means of the said threaded tube e at its outlet or lower end
is screwed into a socket or pipe e which causes the valve f to be positioned internally
and thus prevents all leakage.
In lieu of forming or furnishing the bottom end of the supply vessel b with a
short tube e and the top end with a short tube or nut as described, I may employ
a tube, which passes through the whole length thereof, see Fig. 2. The lower
end of this tube i', which is screwed into the socket e and soldered to the outlet or
lower end of the supply vessel b, serves as a seating d for the disc or other valve f
and the upper end to receive the nut or screwed plug similarly as hereinbefore
described. The valve rod or chain is employed inside of the tube and the lower
end thereof perforated to permit of the oil or other liquid entering the same from
the supply vessel b.
In order to prevent, in case of back pressure, the oil or other liquid from being
disturbed in the vessel I form the upper end of the rod 9, see Fig. 9, with a
thread on which I place a nut h. The latter is arranged to be turned loosely in the
short tube or socket which permits the valve f of closing selfactingly on a back
pressure being exerted thereon. Instead of forming the valve seating at the
lower end of the tube c, it may be formed internally thereof, see Fig. 3, so as to
cause the disc or other valve fto act against the same from the inside of the supply
vessel b.
According to another form of my invention the said disc or other suitable valve f
may be employed separately from the rod g operating the same. This effect by.
placing the said disc or other suitable valve f, see Fig. 4, upon a spring k in the
aforesaid socket or supply pipe which spring k presses the said disc or other
suitable valve against its seating d, from which it is removed by simply screwing
down the aforesaid rod y by means of the nut, or plug h.
In this case as well as in the former the valve rod or chain g may be raised or
lowered by means of a lever in lieu of by a nut or plug h, preferably such as shown
in Figs. 6 & 7, which consists of a lever I formed with a cam m which is pivoted to
the valve rod or chain g and bears against the upper end or tube i of the supply
vessel b.
In lieu of employing a valve of the lift type, as described, I may employ a
partially rotating one, such for instance as shown in Fig. 8.

page_text: In order to prevent all leakage of oil from the joint between the supply pipe e
and the tube c I solder the latter either to the former or I solder a jacket c
surrounding the same to the supply vessel and supply pipe e, as shown in Fig. 1.
The valve arrangement described will not only serve for refilling the supply
vessel but also for feeding the oil to the burner and the valve f itself may be
employed at any convenient part in the outlet pipe e.
Having now particularly described and ascertained the nature of my inven
tion and in what manner the same is to be performed, I declare that what I
claim, is-
"In means for stopping the flow of oil or other liquid from lamp or other supply
vessels."
1st. The application to the outlet end a or pipe e of the supply vessel 6 of a disc
or other suitable valve employed internally thereof, substantially as and for the
purpose specified.
2nd. The valve f specified in the preceding claim formed or furnished with a rod
or chaing and operated externally of the supply vessel, by means of a mut or
plug or lever, substantially as and for the purpose specified.
