Improvements in and connected with Pumps for Raising Liquids
from Barrels and the like.
I, JOHN OAKS ELLISTON, Store Keeper, of Southampton, Suffolk County, State
of New York, United States of America, 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 that class of pumps which are designed to be removably
placed in barrels and used to discharge the same of their contents, and it con-
sists in the peculiar and advantageous construction hereinafter described and
particularly pointed out in the claims appended.
In the accompanying drawing:
Fig. 1. is a sectional view illustrating my improved pump in its operative
position in a barrel.
Fig. 2 is a perspective view of the pump cylinder.
Fig. 3 is a perspective view of a dripper forming part of the pump.
Fig. 4 is a perspective view of the collar which renders the connection of the
dripper to the barrel head substantially air tight.
In the said drawing, similar letters designate corresponding parts in all of the
views, referring to which;
A is an ordinary barrel which, in order to enable it to receive my improve-
ments, is provided in its upper head a or in its side with the ordinary opening
or bung hole b.
B is the cylinder of my improved pump which is preferably formed of sheet
metal, and contains an upwardly opening clack or other suitable valve c, and
a piston d carried by a rod e and having one or more openings f and an upwardly
opening valve g controlling the same. The cylinder is provided at its lower
end on one side with a short screw i designed to be turned into the lower head j
or side of the barrel so as to fix the cylinder against casual movement. This
arrangement of the screw is advantageous since it admits of the lower end of the
pump cylinder approaching quite close to the bottom of the barrel, and enables
the pump to remove all or practically all of the contents of the barrel.
upper end the said cylinder is slightly enlarged as indicated by h and is provided
with a lip arranged as shown in Fig. 1 to discharge liquid as it is raised by
the pump into a vessel placed to receive it.
At its
C is the dripper of my improved pump which is also preferably formed of
sheet metal. The said dripper comprises a body m which is made up of a
bottom n, side walls p, and a hinged cover q and is designed to rest above the
head a of the barrel, and a tubular depending portion r which is designed to rest
in the opening b of the barrel head and loosely receive the pump cylinder after
the manner shown. At its lower end the dripper C rests in a lug s on the pump
cylinder, and adjacent to its upper end it is detachably connected to the said
cylinder, preferably through the medium of a bolt t and wing nut u, as shown.
By reason of the construction just described the pump cylinder and dripper
are securely held together, and yet may be readily disconnected by simply

page_text: removing the bolt and nut and moving the cylinder endwise to disengage
the lugs from the lower end of the dripper tube r. With this done the cylinder B
may be drawn out of the dripper and the tuber of the dripper may then be
readily cleared of any sediment that may have collected therein.
D) is a collar of wood or other suitable material of a less height than the
distance between the bottom of the body of the dripper and the top of the barrel
and which snugly receives the tuber of the dripper and occupies the opening b
in the barrel head. This collar D is exteriorly tapered as shown, and hence it
will be seen that it may be made to snugly fit openings 6 of various sizes, to render
the connection of the tuber to barrel heads substantially air tight.
When my improved pump is to be placed in a barrel, the cylinder B and the
dripper tuber are inserted through the opening and are pressed downwardly
and turned so as to force the screw i into the lower portion of the barrel. With
this done the pump is secured against casual disconnection from or movement
in the barrel, notwithstanding the upward pull exerted incident to the upward
movement of the pump piston. After the pump is secured to the barrel as
described, the collar D is moved down into the hole & when the pump is ready for
operation.
In use the piston of the pump is reciprocated in the usual manner to lift liquid
in the cylinder B, and the vessels to receive the raised liquid are placed on the
bottom of the dripper below the lip of the cylinder. From this it follows
that any overflow of liquid from the vessels will be caught in the body of the
dripper and conducted by the tuber back into the barrel.
-
When the pump is not in use, the cover q of the dripper is closed to exclude
dust from the dripper and barrel, and also to prevent evaporation of the
contents of the barrel.
After the barrel has been discharged of its contents the pump may be readily
removed therefrom and may be as readily placed and secured in another barrel.
It will be appreciated from the foregoing that my improved pump is very simple
and cheap, that it may be readily placed and secured in an ordinary barrel after
an opening as 6 is formed therein, and that the pump cylinder and dripper may
be readily disconnected when it is necessary to free the latter of collected
sediment.
The valve at the lower end of the pump cylinder, and the piston d in said
cylinder may be of any construction suitable to the purposes of my invention
and I therefore do not desire to be understood as confining myself to the con-
struction shown and described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
a
1. The combination of a barrel having an opening b, a dripper comprising
body resting at a considerable distance above the barrel and having a bottom
and side walls and a cover, and a depending tube extending down through the
opening and into the barrel, a pump cylinder loosely arranged in the depending
tube of the dripper and extending up into the body thereof and having the
enlarged portion and lip at its upper end and also having a lug receiving
the lower end of the dripper tube, a detachable connection between the upper
portion of the pump cylinder and the body of the dripper, a screw connected to
the side of the pump cylinder and depending below the lower end of the same
and engaging the bottom of the barrel; said screw having its point disposed
off the longitudinal centre of the pump cylinder, and a removable, exteriorly
tapered collar surrounding the tube of the dripper and occupying the opening b
in the barrel said collar being of a less height than the distance between the
bottom of the body of the dripper and the top of the barrel, substantially as
specified.
2. In a barrel pump, the combination of a dripper comprising a body adapted to

page_text: rest at a distance above the barrel, and a depending tube adapted to extend
through an opening in the barrel, a pump cylinder extending through and
detachably connected to the depending tube of the dripper; said cylinder being
of a length to support the dripper body at a distance above the barrel, a screw
connected to the side of the pump cylinder and depending below the lower end of
the same and adapted to engage the bottom of a barrel; said screw having its
point disposed off the longitudinal centre of the pump cylinder, and a collar
surrounding the tube of the dripper and adapted to occupy the barrel opening;
said collar being adapted to be moved upwardly on the dripper tube and out of the
barrel opening, substantially as specified.
