I, FRED CLINTON SMITH, of Delavan, in the State of Wisconsin, United States
of America, Gentleman, 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:-
_
My invention relates to oil pumps, which are used in connection with cans con-
taining oil, and which extend down to or near the bottom of the can, and are
provided with nozzles projecting up above the top of the can, the pump being
so constructed that a lamp placed on top of the can may be filled without liability
of overflowing as any excess of oil supplied to the lamp will be drawn back into
the can.
In the accompanying drawing,
Figure 1 is a perspective view partly broken away of an oil can, provided with
a pump constructed in accordance with my invention.
Figure 2 is an elevation, partly in section of the pump removed from the can.
Figure 3 is a vertical section on the line x, x, Fig. 4.
Figure 4 is a horizontal sectional view on the line y, y, Fig. 3.
Figure 5 is a similar view on the line z, z, Fig. 3.
Figure 6 is a view of the nozzles looking from the underside.
Figure 7 is a vertical section on the line a, a, Fig. 4.
To enable others to make use of my invention I will proceed to describe the
same in detail, referring to the said drawing in which the reference numeral 1
designates an oil can or receptacle of any ordinary or suitable construction
having a circular opening in the top, to allow the pump to be inserted in the can.
The numeral 2 designates the pump cylinder having a valve opening 3 in its
lower end provided with a valve 4. The upper end of this cylinder is secured to
a circular disk shaped cap provided with a flange 6, which rests upon the top of
the can and is supported thereby. The upper end of the cylinder and the cap are
formed with openings for the passage of the pump rod 7. Said cap around the
opening is formed with a circular depression 8, so that any oil which may be
drawn up by said rod and the piston attached thereto will be caught in said
depression and be conducted back into the can, through the openings through
which said rod passes.
The numeral 9 denotes the piston secured to the inner end of the rod and
10 a knob at the upper end thereof by which it may be operated. Secured to one
side of said cylinder at the lower end is a cylindrical valve casing 12, which com-
municates with the said cylinder by means of a passage 13. This valve casing
is provided with a partition 14, having a central opening 15, above which is
located a valve 16. Connected with the upper end of said casing is a pipe or
tube 17, on the upper end of which telescopes a tube 18, the upper end of which
is curved and provided with a curved nozzle 19.

page_text: Secured to one side of the pump cylinder is a curved plate 20, forming a
chamber 21, closed at top and bottom. Communicating with the lower end of
this chamber is a pipe 23, with which telescopes a curved pipe 24, having a curved
nozzle 25, similar to those above described. The ends of these nozzles converge
towards each other and their inner sides are flattened as seen in Fig. 6.
chamber 21 communicates at its upper end with the pump cylinder by means of
an opening 26.
The
Near the upper end the pump cylinder is formed with an opening 27, to enable
the oil forced upwardly by the piston to escape back into the can, and with a
partition 28, formed with a central opening 29, through which the pump rod
loosely passes. A valve 30 and washer 31, which are movable on the pump rod
serve to close said opening 29 on the downstroke of the plunger. In front of
said opening is a shield 35, to prevent the oil splashing against the cap.
The inner ends of the pipes 18 and 24, pass loosely through tubular sleeves 32,
secured to the underside of the cap 5, and the lower ends of the pipes 17 and 23
are cut away or pointed so as to form guides 34, which enter between the sleeves
and the pipes 17 and 18 and thus guide said pipes in place.
In using the pump it is inserted in the can through the hole in the top and
secured thereto in any suitable manner. When it is desired to fill a lamp the
latter is placed on the can and the pump rod operated. The oil will be drawn
into the cylinder on the upstroke of the piston and on the downstroke will be
forced into the valve casing 15, up through the pipes 17 and 18, which are the
supply pipes and out through the nozzle 19, into the lamp. This operation will
continue until the lamp is filled and the fluid therein reaches the said nozzles,
when the supplies will be drawn by the downstroke of the piston into
pipes 24 and 23 which are suction pipes, into the chamber 21, and through the
opening near the upper end, into the pump cylinder. On the next upstroke of
the piston this oil will be expelled from said cylinder through the opening 26
into the can. By this construction it will be impossible for the lamp to overflow
as any excess of oil is sucked out of the same into the pump as fast as fed to the
lamp.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination of the pump cylinder, having a valve at the lower end,
and an opening near the upper end, the cap to which said cylinder is secured, the
pump passing through said cap, the piston, the valve and washer, movable on
said rod, the valve casing with which the pump cylinder communicates, the pipe
connected therewith, the telescoping pipe and nozzle, the curved plate secured to
the cylinder forming a closed chamber and provided with passages at the upper
and lower ends, the pipe communicating with said lower passage, the telescoping
pipe and nozzle, substantially as described.
2. In a pump of the character described, the combination with the cap, the
sleeves secured thereto and the telescoping pipes, passing through said sleeves and
the nozzles, substantially as specified.
3. In a pump of the character described, the combination of the curved nozzles
having their ends cut away or flattened at the inner sides, substantially as
described.
4. In a pump of the character described, the combination of the cap, the sleeves
secured thereto, the telescoping pipes having their inner ends cut away and pointed
and the pipes with which said telescoping pipes engage, substantially as specified.
5. The combination with the cap having openings therein, the pump cylinder
having an opening near the upper end, the valve at the lower end of the cylinder,
the piston, the pump rod, the movable valve and washer on said rod, the valve
casing and valve, the pipe connected therewith, the telescoping pipe and nozzle,
the curved plate secured to said cylinder, the pipe connected with the lower end

page_text: thereof, the telescoping pipe and nozzle, the sleeves secured to said cap and the
shield secured to the pump cylinder in front of the opening at the upper end
thereof, substantially as described.
