PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
I ALEXANDER MELVILLE CLARK of the firm of A. M. & Wm. Clark
of 53, Chancery Lane, in the County of Middlesex, Fellow of the Chartered
Institute of Patent Agents, do hereby declare the nature of this invention (a com-
munication to me from abroad by John Emile Borne of 80 South Street New.
York City, United States of America, Exporter and Oil Manufacturer) to be as
follows:-
This invention relates to an improvement in the feed for oil cups and equivalent.
lubricating devices, and has for its object to provide a feed which may be used
without a wick, and capable of conveying the most viscous oil from the lubricating.
device to the bearing in regulated quantity.
The feed device of this invention is in the form of a siphon, the short member of
which dips into the oil contained in the oil cup and is provided with a valve.
adapted to close against a seat in the lower extremity of said short member. The
valve is preferably of conical form and it is attached to a rod which screws into an
aperture in the upper part of the siphon. The lower extremity of the long member
of the siphon is preferably made conical in order that the outlet may be of much ..
less diameter than the diameter of the body of the siphon.
The location of the valve may, it is evident, be somewhat changed without
departing from the spirit of the invention, and that the valve may be otherwise.
manipulated, and that the entire device may be placed in a lubricating device.
in any manner best adapted to the construction of the device and to obtain a
proper feed.
.
When applied to an ordinary oil-cup the long member of the siphon would be
placed in the tube of the cup usually employed to hold the wick, and conducts the
oil, contained in the body of the cup and siphoned through the shorter end of the
device to the bearing to be lubricated. By manipulating the valve more or less oil
may be fed from the cup to the bearings, and by decreasing the area of the outlet,
of the longer member-the valve at the end of the shorter member being closed,
thus holding the oil in suspension-the device may be removed from the cup or box
without the escape of the oil, as the pressure of the atmosphere will be directly
against the central portion of the column of oil and not against the said column at
the sides thereof.

Improvements in Lubricators.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Chartered Institute
of Patent Agents, do hereby declare the nature of this invention (a communication
to me by John Emile Borne, Exporter and Manufacturer of Oils, of 80, South
Street, New York City, in the County and State of New York, United States of
America) 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 improvement in the feed for oil cups and equivalent .
PB77

page_text: lubricating devices and has for its object to provide a feed which may be used
without a wick and capable of conveying the most viscous oil from the lubricating
device to the bearing in regulated quantity.
The invention consists in a siphon feed, the same being provided with a valve
whereby the quantity of oil to be fed may be controlled, the siphon feed being so
constructed that the siphon may be removed from the lubricating device and laid
aside without danger of the oil contained therein and beld by a vacuum, oozing out
or spilling and thus destroying the siphon effect.
.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar figures and letters of reference indicate corresponding
parts in both the views.
Figure 1 is a central vertical section through a lubricating device, illustrating
the application of the siphon feed, the said siphon feed being also in vertical
section, and Figure 2 is a horizontal section, taken practically on the line 2-2 of
Figure 1.
The feed device constituting the feature of the invention is in the form of a
siphon, 10 being the long member and 11 the short member thereof. Preferably
in the upper end of the short member there is a threaded aperture 12 through
which passes a rod 13 into the said member of the siphon; the upper portion of
the rod being screw-threaded exteriorly, as illustrated at a in Figure 1, the rod
being turned through the medium of an attached knob 14 or any equivalent thereof.
The lower end of the rod 13 has a valve 15 rigidly secured thereto, the said valve
being adapted to close or to partially close the lower end of the siphon member:
in which the rod is located. The valve is preferably of conical shape and the inner
surface of the siphon at the extremity surrounding the valve is bevelled to form
a seat a' therefor. The lower extremity of the long member of the siphon is
preferably made conical, as illustrated at a' in Figure 1, and by thus shaping this
portion of the siphon the outlet is of much less diameter than the diameter of the
body.
I desire it to be distinctly understood that the location of the valve may be
somewhat changed without departing from the spirit of the invention and that the
valve may be manipulated otherwise than in the manner shewn and that the
entire device may be placed in a lubricating device in any manner best adapted to
the construction of the device and to obtain a proper feed.
In the drawing the feed is illustrated as applied to an ordinary oil cup and the
long member of the siphon is placed in the tube of the cup usually employed to
hold the wick and conducts the oil contained in the body of the cup and siphoned
through the shorter end of the device to the bearings to be lubricated. It is evident
by manipulating the valve 15 more or less oil may be fed from the cup to the
bearings, and further that by decreasing the area of the outlet of the long member
-the valve at the end of the short member being closed thus holding the oil in
suspension-the device may be removed from the cup or box without the escape
of the oil as the pressure of the atmosphere will be directly against the central
portion of the column of oil and not against the said column at the sides thereof.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is―
1. A feed for lubricating devices, substantially as shewn and described.
2. As an improved article of manufacture, a siphon feed provided with a valve,
as and for the purpose specified.
3. The combination, with a siphon feed, of a valve located in one of its members
and adapted to control the size of the opening therein, as and for the purpose
specified.

page_text: 4. A valved siphon feed having its exit opening of less diameter than its body,.
as and for the purpose specified.
5. The combination, with a siphon adapted for the purpose described and provided
with an outlet of less diameter than its body, of a valve controlling the inlet of
the siphon, as and for the purpose specified.
