PROVISIONAL SPECIFICATION.
Improvements in Railway Carriage-roof and like Lamps.
WILLIAM CARPENTER Railway Porter G.N.R. Railway 19 Queen's Street
Grantham Lincolnshire do hereby declare the nature of this invention to he as
follows:-
In Railway Carriage Roof & like Lamps commonly used for the burning of colza
and similar expensive oils to so control the oil flow from the lamp cistern to the
burner as to permit of petroleum and similar cheaper oils being used and also by thus
controlling the oil flow to extinguish the light without removing the lamp from its
position in the carriage. The controlling of the oil flow is preferably achieved by
either one of the two following means, ri. :-First, by a rod fitted with a plug at the
bottom end carrying a rubber washer there being an ordinary knob at the top for
operating such rod which is designed to pass up and down the feed tube which conveys
the oil from the lamp cistern to the burner when the lower end of the rod is drawn
nearer to or pushed further from the cistern hole communicating with the feed tube
the oil flow through the cistern hole is thereby controlled at will. Second, the same
object may also be gained by a slide being fitted inside the cistern to open or close the
cistern hole leading to the feed tube such slide being operated by a knob jointed
thereto working in a slot through the top of the cistern. The extinguishing of the
light is accomplished by the cistern hole leading to the feed tube being closed by
means of either the rod or slide above described thereby stopping the oil flow when the
light dies out at once through want of such oil.
Dated this 28th day of January 1890.

COMPLETE SPECIFICATION.
Improvements in Railway Carriage-roof and like Lamps.
WILLIAM CARPENTER 19 Queen Street, Grantham, Lincolnshire Foreman Railway
Porter 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 :-
Figure 1, No. 1 is the oil cistern, No. 2 is the cistern conducting pipe, No. 3 is the
burner conducting pipe, No. 4 is an adjustable rod, No. 5 is the piston or plunger,
No. 6 is the knob for operating same, No. 7 is the oil hole leading to wick; by press-
ing the knob No. 6 down the oil has a controllable outlet to the wick through the hole
No. 7; by means of the plunger the whole of the oil hole No. 7 may be made use of
or only just so much of it as may be desired. If desired the pipe No. 2, Figure 1, can
be made solid at the bottom end and the rod No. 4, Figure 1, carried through the
bottom of the pipe No. 2 and riveted thereto then by rotating the pipe No. 2 by means
of the knob No. 6 the oil supply could he also controlled. Figure 2; No 1, is the
oil cistern, No. 2 is a tap, No. 3 is a handle for working same; this tap achieves the
same object as the plunger in Figure 1. Figure 3; No 1 is the cistern, No. 2 is a
rod with a conical shaped piece at the under side and a screwed piece at the top side,
the latter by means of the thumb nut No. 3 is made to regulate the oil supply and
thus achieve the object of the plunger No. 5 in Figure 1. Figure 4; No. 1 is the
cistern, No. 2 is a similar rod and operated in a similar way as No. 2 in Figure 3, but
having a wing valve No. 4 attached to its lower end which, raised by the thumb nut
No. 3, also regulates the oil supply. Figure 5; No. 1 is the cistern, No. 2 is a similar
rod and operated in a similar way as No. 2 in Figure 3, but having a disc No. +

page_text: (preferably of indiarubber or leather) secured to its lower end which, raised by the
thumb nut No. 3, also regulates the oil supply.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, 1 declare that what I claim is:
In Railway Carriage Roof & like Lamps commonly used for the burning of colza
and similar expensive oils to so control the oil flow from the lamp cistern to the
burner as to permit of petroleum and similar cheaper oils being used.
Dated this day 27th of September 1890.
