COMPLETE SPECIFICATION.
Improved Lubricator for Cycle-bearings and other Mechanism.
I, ELLIS MENKE, Manufacturer, of 41, Blittersdorffplatz, Frankfort on the
Main, Germany, 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 an automatic cycle lubricator constructed in such a
manner, that no dust can enter the oil receptacle during the process of lubrication.
In the accompanying drawings,
Fig. 1 is an axial section of a lubricator embodying my invention;
Fig. 2 represents a modification, and
Fig. 3 is a section along line A-B of Fig. 1.
The lubricator chiefly comprises a spherical receptacle k, into which is soldered
at the bottom a screw-threaded connecting pipe u for securing the lubricator to
the bearing, while the top is provided with an opening o for the reception of oil.
In order to securely close the opening against dust, a valve v is introduced into
the receptacle k before the latter is soldered together with the tube u, and also a
volute spring fadapted to press the valve v against the fill-opening o.
If it is desired to charge the oil receptacle, the valve v is pressed down slightly
by the spout of the lubricating can, and the oil allowed to flow down through the
opening o. After the removal of the lubricating can, the valve vis automatically
closed by the action of the spring f, so as to prevent the loss of oil and the intrusion
of dust during the motion of the vehicle.
The valve spindle is flattened at its lower end a which extends into the oil
outlet, in order to guide the valve rod in the said opening and to diminish the flow
of oil.
If it is desired, that no oil should run out of the lubricator while it is being
charged, the valve spindle i may be made thick enough to close the orifice for the
discharge of oil, while the valve is being pressed down. In this case the valve
spindle is bevelled off at the lower end.
In Fig. 2 the valve carries a small funnel m provided with two radial apertures n,"
through which the oil flows into the interior of the oil receptacle, when the funnel
is pressed down.
To guide the spout or nozzle of the oil can, the receptacle k may have a funnel-
shaped flange around the opening o.
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:
A device for the dustproof lubrication of cycle bearings and other mechanism,
comprising in its construction an oil-receptacle provided with a fill-opening and
adapted to be mounted on a bearing, and a valve situated in the interior of the
said oil receptacle, said valve being accessible from outside and adapted to close
the fill opening during the lubrication and to open by yielding to external pressure,
with or without simultaneous closing of the discharge opening, substantially as
described.
