COMPLETE SPECIFICATION.
Improvements in Lubricating Cans.
I, JOHN ROTHERHAM, of 27, Spon Street, Coventry, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in lubricating cans and my invention
consists in a lubricating can which is dust proof and especially adapted to be used
by cyclists, said can being provided with improved means hereinafter described
for cutting-off the supply of oil through the spout.
In order that my invention may be readily understood reference is made to the
accompanying drawings wherein like letters of reference indicate corresponding
parts throughout the several figures and in which:
Fig. 1 shows one part of my improvements:
Fig. 2 shows the other part.
Figs. 3 and 3 show an alternative construction of said two parts.
Fig. 4 shows in sectional side elevation a lubricating can provided with my
improvements.
In carrying my invention into practice I employ a disc A which I attach to a
suitable part of a lubricating can L, said disc A having an aperture a and a
slot or equivalent of suitable dimensions and for the purposes hereinafter
described. If desired said disc. A may be formed with a tongue e shown in Fig. 1
which will ensure that said disc will not turn in its seating.
On the outer side of the disc A I provide a cap or equivalent B which cap is
in contact with and covers the disc A and is capable of being rotated thereon.
Said cap B is provided with a pin which enters the slot b in the disc A and by
means of which the rotary movement of the disc B is limited by reason of said
pin & coming in contact with either one end or the other of the slot b.
The cap B is also provided with an aperture d which corresponds with the
aperture a in the disc A, the arrangement being such that when the
cap B is.
turned its full extent in one direction the aperture d will coincide with the
aperture a and a clear passage consequently left for the passage of the oil into
the spout S which spout is carried by the cap B as shown in Fig. 4. But if the
cap B be turned to its full extent in the opposite direction, the aperture a will
be shut off by the cap B and the flow of oil cut off.
For the purpose of ensuring sufficient frictional contact between the cap B and
the disc A, I prefer to make one or other of the parts A, B slightly convex about
as shown in Fig. 3, so that when the cap B is forced tightly against the disc A the
frictional contact between said parts will be considerable and the wear between
them will be "taken up."
I do not confine myself to any particular manner of fastening the disc A or the
cap B in position.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a lubricating can, a disc covered with a revolvable cap, said disc and cap
having corresponding apertures respectively, a pin fixedly attached to the cap
said pin entering a slot in the disc so as to limit the circular movement of the
cap on the disc all for the purposes and substantially as set forth.
2. In a lubricating can a disc normally depressed by a revolvable cap so as to
increase the frictional contact between and also so as to take up the wear between
such parts said disc and cap being provided with a common aperture to permit
of the passage of oil and the cap being provided with a pin which enters a slot
in the disc all for the purposes and substantially as set forth.
Dated this 13th day of October 1897.
