the State of Massachusetts, of the United States of America, for the
Invention of "CERTAIN NEW AND USEFUL IMPROVEMENTS IN OIL FEEDERS,
VESSELS OR CANS FOR OILING MACHINERY."- Partly a communication.
Sealed the 17th February 1857, and dated the 4th December 1856.
COMPLETE SPECIFICATION filed by the said. Ebenezer Daggett Draper
and George Draper at the Office of the Commissioners of Patents, with
their Petition and Declaration, on the 4th December 1856, pursuant to
the 9th section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT
KNOWN, that we, EBENEZER DAGGETT DRAPER and GEORGE DRAPER, of
the State of Massachusetts, of the United States of America, are in possession
of an Invention of Certain "NEW AND USEFUL IMPROVEMENTS IN OIL FEEDERS,
VESSELS, OR CANS FOR OILING MACHINERY," (the same in part having been
invented by us and in part communicated to us by one or more persons
residing abroad). And we do hereby declare that the nature of our Invention.
and the manner in which the same is to be performed, are fully set forth and
represented in the following Specification and the accompanying Drawings.
The nature of our Invention consists mainly of certain improvements in the
oil can or feeder, for which Letters Patent, bearing date the Thirteenth day of

page_text: August, A.D. 1855, have been granted to us by Her Majesty Queen Victoria,
such improvements being specially defined in the following description and the
claims made therein.
Figures 1, 2, 3, 4, and 5 of the Drawings above mentioned, exhibit vertical
sections of our improved oil feeders or cans.
In Figures 1 and 2, A denotes the body or oil reservoir of a can, the same
being provided with a discharging spout or pipe B, which is surrounded at or
near its lower end by an annular trough or cup C, from the bottom of which
a tube D extends downward to and into a conical vessel or chamber E,
arranged within the body or oil reservoir A, and either at the lower part
thereof, as shown in Figure 1, or at or near the upper part thereof, as shown
in Figure 2; the said tube D enters the chamber and terminates at a short
distance from its bottom. Another pipe F extends out of the top of the
chamber E and upwards toward the discharge pipe B, and is made either to
enter the same or to terminate a short distance below it, as shown in the
Figures. The chamber E may be arranged in any other proper position within
the body or oil reservoir.
The objects of our improvements are, first, to cause any oil which may run
down on the outer surface of the discharge pipe B to find its way either into
the body A of the can, or into the said discharge pipe, and without running
down on the external surfaces of the sides of the can so as to soil or injure the
same, or a bench or other thing on which the can may be placed.
Second, to properly vent the can, so as to permit the oily contents thereof
to freely flow out of its discharge pipe when the can is turned down or inverted
for the purpose of oiling a piece of machinery.
Third, either to regulato or arrest the flowage of such oil, as occasion may
require, while the can or feeder is so turned down or inverted.
Fourth, to so combine or affix the air chamber E and its inlet and outlet
tubes with the screw cap of the vessel A as to enable such chamber and its
tubes to be removed together and with the screw cap from the vessel.A, in
order that the said vessel may be easily clenused, or any extraneous matters
removed from it, as occasion may require.
By arranging the tube F so that it will pass upwards from the chamber E
instead of downwards from it, as shown in the Specification of our Patent
dated August 13th, A.D. 1855, oil of the body or reservoir A, when the can
is turned down or inverted, will not run into the tubo F so as to choko it and
impede the proper passage of air through it; besides this, when the can is
turned down, the tube D will be free of oil, so that air can pass through it
into the chamber E; the oil which may previously have passed through such

page_text: tube and into the chamber E being caused to flow out of the said chamber and
through the pipe F. The oil that enters the drip cup c of the cans, shown in
Figures 1, 2, 3, and 5, flows into the reservoir A after passing through the
chamber E and its discharge pipe. When the discharge pipe of the chamber E
extends downwards from the said chamber and into the oil reservoir, the oil
that may be in the latter will enter the said pipe, and of course during tho act
of inverting or turning down the can, all the oil that may be in the tube F
would have a tendency to flow into the oil chamber; this oil meeting the air
flowing through the tube would operate, more or less, to prevent its ascent,
and thus the can would be improperly vented. Our improved arrangement,
shown in Figures 1, 2, 3, and 5, obviates that difficulty; and besides this, it
overcomes another, incident to the action of our patented can, in which the
oil which is in the discharge tube of the reservoir (especially when such tube
is long), by falling back into the reservoir after the can has been turned up or
set down upon its bottom, will so act on the air and oil therein, or in the air
chamber, as to cause oil to be ejected from the catching recess.or cup, so as to
run down on the outside of the can or be thrown upon any object in the vicinity
thereof.
In Figures 3 and 4, the discharging mouth of the vessel A is shown to
have a diameter somewhat larger than that of the air chamber E, the said
mouth being closed by a cuppel cap C screwed into it, as shown at a. The air
vessel or chamber E is fastened to the cap C either directly, as shown in
Figure 4, or indirectly and by the pipe D, as shown in Figure 3, in which the
pipe is represented as fastened both to the cap and air chamber, the discharging
pipe B extending upwards from the cap C. By unscrewing the cap C, so as to
remove it from the oil reservoir, we at the same time may separate and draw
out of the same the air vessel and its pipes of inlet and discharge, so as to leave
the vessel A free to be cleansed, or to enable the removed parts to be applied
to another such vessel A, in case the first may have become damaged or leaky.
When the tubo B is very long, as it sometimes has to be in oil feeders for
Jocomotive or various other engines, we arrange within it a valve G, so as to
operate against and close the inner end of the discharge tube B, such valve
and its arrangement being shown in Figure 5. This valve may have its stem b
jointed to one arm of a bent lever c, made to turn on a fulcrum d, and to have
a thumb slide e (surmounted by a button or head k) extending from its other
arm and out of the reservoir and upper part of its handle f, as shown in
Figure 5. A spring 9 applied to the valve stem, and a cross bar h through
which the said stem may slide, serves to depress the valve away from its seat i.
In order to force the valvo towards its seat, a person should press his thumb

page_text: or finger on the button of the slide e. By means of the valve G and its
operative mechanism, the flowage of the contents of the can through the tube B
may be arrested or suffered to continue, at any time while the can or feeder is
turned down or inverted. When the valve is closed on its seat, the pressure
of the atmosphere will prevent the oil that may be in the discharge tube from
running out of it. If desirable, the stem e may be made tubular, so as to
allow air to pass through it and into the can.
What we claim is the improved arrangement of the outlet tube of the air
chamber E, viz., so that it may extend upwards out of the same, while the inlet
tube or that projecting from the cup C may pass down from such cup, whether
the chamber be arranged either at the upper or lower part of the oil can or in
any other proper part of the same.
We also claim the improvement of so affixing or combining the chamber E
with the screw cap, and constructing the cap and mouth of the can, that such
chamber or air vessel with its pipes and the screw cap may be capable of being
bodily removed from the can.
We also claim combining with the oil reservoir and its discharging tube an
air inlet and a valve, and mechanism by which such valve may be operated,
substantially in manner and for the purpose as described.
In testimony whereof, we have hereunto set our signatures and seals, the
Twentieth of November, One thousand eight hundred fifty-six.
