An Improved Oil Can for Lubricating Velocipedes or
other Machinery.
THOMAS HENRY HAWLEY Castlegate Malton Yorks. Draper and Cycling Outfitter
and EDMUND JACKSON Welham Road, Malton Yorks. Architect do hereby declare the
nature of this invention to be as follows:-
This invention is applied to oil cans suitable for lubricating velocipedes and other
machinery and consists of an improved arrangement for permitting the escape of the
lubricating or other material contained in the reservoir, together with provision for
operating the same. It is provided with a spindle guided in the proper directions
with valve fixed on or forming part of spindle, which valve is pressed up to the valve
seating in end of nozzle or spout by the spiral spring thereby closing the valve-
opening and retaining the fluid. Pressure on the flexible side, sides or bottom of
reservoir by means of levers suitably provided presses the spindle in the reverse
direction to the action of the spring thereby opening the valve and allowing the
escape of the fluid contained in the reservoir, and which fluid is forced out also by the
pressure on the side, sides or bottom of reservoir. The valve is provided at its
external end with a needle or point for the purpose of keeping clean and free the
valve opening and preventing the admission of material likely to obstruct the passage
or opening aforesaid.

An Improved Oil Can for Lubricating Velocipedes or
other Machinery.
We, THOMAS HENRY HAWLEY of Castlegate Draper and EDMUND JACKSON, of
Welham Road, Architect both in Malton, Yorkshire, do hereby declare the nature of
our said invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of this invention is to manufacture improved oil-cans or oil feeders for
lubricating velocipedes, and other articles and machinery.
Our invention consists of a can, of any convenient form and size, preferably made
of tin or brass, and fitted with a nozzle for delivering the lubricant. The inside of
the nozzle, near its outer end, is formed into a valve seating, and a spindle is placed
inside the nozzle, and suitably guided; the outer end of the spindle is formed to fit
the valve seating, against which it is pressed, by a spiral or other spring, and
thereby forms a valve.
One or more side or sides or the bottom or other part of the can, is or are buckled
and made to bulge, in order that it or they may be capable of being pressed
inward by the thumb or finger, and resume its or their normal shape or shapes
on the removal of such pressure. The motion of the buckled plate is utilised in
withdrawing the spindle from the valve seat, and thereby permitting the flow of
oil, the buckling of the plate or plates causing its expulsion, and the spiral or
other spring returning the spindle to its seat and closing the valve; thus preventing
both leakage of oil and entry of dust and dirt.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.

dd are two provisions for supporting the transverse axle e. o is the nozzle. fis a
bell crank lever, one end of which impinges against the buckled plate a, which is
preferably protected from wear by a plate of metal g affixed thereto, and the other
end enters a slot in the spindle g. is a provision for guiding the lower end of the
spindle is a spring surrounding a portion of the spindle; and pressing the same
upwards. n is a screw cap covering the hole for filling the can.
When the plate a is pressed inwards, the lever draws down the spindle g, and
thereby opens the valve m, thus permitting the flow of oil through the valve m.
When the pressure is removed from the plate a, the lever f immediately returns to its
normal position, permitting the spindley to be pressed to the valve seating by the
spring k, thus closing the valve m.

bottom, the lever being made straight, and a connecting rod p being fitted to move
the same.

In Fig. 6 the conical end of g is made flush with the outer end of o. In
Fig. 7 the valve is placed farther back in order to protect it from damage, when
accidentally dropped.
The cans sometimes have handles of various kinds fitted to them, and also air vents
and other conveniences for admitting the atmosphere, and for replenishing with oil
or other lubricant.
Having now particularly described and ascertained the nature of our said Invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. The manufacture and use of oil cans constructed arranged and operating
substantially as hereinbefore described and shewn on the drawings.
2. In the construction of oil cans for the purposes aforesaid, the special arrangement
of the valve m, opening inwards, and operated by the buckling of one or more of the
sides or the bottom, substantially as herein before described and shewn on the
drawings.
3. The general construction, arrangement and combination of the several and
respective parts, together forming our invention of an improved oil-can for lubricating
velocipedes and other machinery, substantially as herein before described and shewn
on the drawings.
