COMPLETE SPECIFICATION.
Improvements relating to Lamps, Oil Cans, or the like.
I, ISAAC WEBSTER, of Church Street, Kirkstall, near Leeds, in the County of
York, Tinner, 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 :-
My invention has reference to certain improvements in lamps, oil cans, or
the like.
Hitherto the feed holes of lamps, oil cans and the like have been closed by
means of a screwed lid or cover.
It is found that the screwing on and off of such lid takes up too much time, is
liable to become easily damaged or deranged, and is generally unsatisfactory.
The object of my invention is to provide improved apparatus for opening and
closing the feed holes of lamps, oil cans and the like, which shall supersede the said
screwed lid, and obviate the disadvantages aforesaid.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a side elevation showing my improvements applied to lamp.
Fig. 2. is a plan of Fig. 1.
In carrying out the object of my invention I employ a domed top, lid or dished
topped cover A, and a flanged ring B, made to correspond with the said lid or
cover. The lid or cover has two or more recesses C, and the ring, feedhole, or
mouth of the vessel or feeder D, two or more grooved studs or clutches E, to
correspond with the recesses in the said lid or cover, so that when they are brought
together the lid or cover can be taken off, or removed as required.
Or the lid or cover can be moved or turned past the grooved studs or clutches E
so as to close the feed hole. On that taking place the two flanged surfaces meet
and prevent leakage of the oil or other liquid, the flange of the said lid or cover
[Price 6d.]

page_text: moving in the grooved studs or clutches E, and binding itself tight, the said flange
being made slightly smaller at the parts nearest the recesses.
The lid or cover A may be fastened to the lamp or can by means of a piece of
chain in the usual manner.
The lid or cover A and flanged ring B are made slightly taper so as to obtain
the necessary binding contact of the parts. The flanged ring B and grooved studs
or clutches E are cast, rivetted, soldered, or otherwise secured.
The said improved apparatus may be made of cast metal, or of steel, or may be
drawn or pressed out of brass, copper, tin, or other suitable metal by the aid of
machinery.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
For closing and opening the feed holes of lamps, oil cans, and the like, the com-
bination of lids or covers A having recesses C, flanged rings B, and the grooved
studs or clutches E, operating for the purposes such as shown and described.
