Combined Pump and Bung for Drums or other Vessels containing
Liquids.
We, ALBERT JAMES DEWHURST, of Rose Cottage Tarden, Mellor, in the County
of Derby, Varnish Manufacturer, and EDWIN BLAKE SMITH, of 2, John Dalton
Street, Manchester, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows:-
Our invention consists principally of a simple force pump, the body of which
having an open top and closed bottom is affixed or secured to the bottom or side
of the drum cask tank or other vessel, which contains the liquid to be raised,
and is arranged with suitable inlet holes made in the side of the body, and a
little above the bottom of the drum or other vessel, and through which the
liquid will flow into the body of the pump when the plunger is above the afore-
said holes, and at the top of its stroke. The plunger consists of an ordinary
piece of metal fitting in the internal sides of the body, and having a suitable
packing ring if necessary. Secured to the centre of the plunger is a tube or pipe
opening into the body of the pump, and up which the liquid can flow; this tube
passes up through the bung and at the top is provided with a bent pipe the
two elbows of which are of unequal length, (which may be utilised as a handle
for the pump) so arranged that when the long elbow is attached to the tube
passing through the bung, the short elbow is sufficient distance above the drum
or other vessel to enable a receptacle to be placed under the same to catch the
liquid as it is forced out; when the short elbow is fixed or secured to the afore-
said tube, the end of the long elbow may be used to close an aperture in the top
of the drum or other vessel provided for the venting of the drum or other vessel,
and for the return of spilt liquid on the top of the drum or other vessel. The
tube is also provided with two stops to regulate the stroke of the plunger, one
of which stops we may use as a lock to hold the tube in its lowest position, and
so prevent the extraction of liquid from the drum or other vessel, except by the
disconnection of the same. The bung through which the tube passes consists
principally of a disc or plate, bossed in the middle and bored out for the tube,
and having two projecting lugs or ears on the outside, opposite each other, for
the purpose of turning the plate about its centre by hand or other means, the
bottom of the plate is provided with a washer of leather, or other material, for
the purpose of making a liquid tight joint on the top of the drum or other
vessel. The plate or disc is cut away on opposite sides for rather more than
the quarter of the circumference, in each case leaving a short concentric ring
of metal, or other material, projecting beyond the plate or dise to the ears or
lugs these concentric rings slide under two concentric clamps attached to the
top of the drum or other vessel. When the plate or dise is turned on its axis.
these clamps are rather more open at the front than at the back, and therefore
when the plate or dise is turned on its axis, the concentric rings, attached to
ame, are wedged on to the top of the drum or other vessel, by sliding under the
clamps, and so keeping a liquid tight joint.

page_text: We may also use one or more ears or lugs and clamps, for the purpose of
attaining this object; the plate or disc may be likewise fixed in one position,
and the clamps having inclined edges, made movable, to slide or screw on top
of the plate, to attain the same object. During the operation of pumping we
may also use a little tundish, fixed or placed in the vent hole before mentioned,
for the purpose of more conveniently allowing any waste or spilling liquid to
return into the drum or vessel.
The operation of pumping the liquid from the drum or vessel consists princi-
pally as follows. The plunger is at the bottom of its stroke, the long elbow is
fast in the vent hole, so that everything is secure and rigid, the tube and plunger
is raised to the top of its stroke by lifting the top of the bent tube, and so with
drawing the long elbow from the vent hole the short elbow is detached from
the tube, and the long elbow is affixed to it, meanwhile liquid has flowed in
through the holes in the side of the cylinder, and under the plunger, by then
pressing down on the top of the bend, the liquid, which is inside the cylinder,
is compelled to flow up the tube, the plunger having covered the holes in the
side of the cylinder, and so run into any receptacle placed underneath the short
elbow the stroke being controlled, as before mentioned, by two stops affixed to
the tube or bung. The bung is of such size as to enable the plunger and tube
to be withdrawn from the drum or other vessel, when it is unslacked, and also
to facilitate the cleaning of the inside of the drum or vessel.
Dated this 22nd day of March 1898.

COMT DELE DITUIFICATION.
Combined Pump and Bung for Drums or other Vessels containing
Liquids.
We, ALBERT JAMES DEWHURST, Rose Cottage, Tarden, Mellor, in the County
of Derby, Oil Refiner, and EDWIN BLAKE SMITH, Brook Lea, Mellor, in the
County of Derby, Engineer, late of 2, John Dalton Street, Manchester, County
of Lancaster, 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:-
The invention has for its object the construction of a combined pump and
bung for drums, tanks, or any other vessel containing liquids, the pump being
of the type whereby the liquid is forced up an outlet tube, without the use of
valves, and the bung of the flat type, being used not only for the keeping of a
tight joint, easily replaceable, but also to act in conjunction with the pump tube
or not.
Fig. 1 is a sectional elevation of our improved combined pump and bung
shown as applied to an ordinary oil drum and shows the pump and tube in a
position ready for pumping and also the screwed vent hole.
Fig. 2 is a plan of the top of the drum showing the bung tightened up and
otherwise in all respects as the elevation.
Fig. is a plan of the top of drum with the handle part of tube reversed
and screwed into vent hole and also the coupling forming a joint on top of
bung.
Fig. 4 shows the bung in position ready to be lifted off, or tightened as the
case may be, after the tube is unscrewed."

and shows the connection made between the cylinder or dish and the bung, to
keep same in position.
Fig. is a further sectional elevation of the pump and bung shown as applied
to a bottle or decanter.
The invention consists principally of a dish or cylinder A Fig. 1, of metal,
glass or other suitable material, closed at one end and open at the other, and
having at the open end holes, slots or ports in the sides of dish or cylinder to
allow the influx of the liquid into the aforesaid dish or cylinder.
The cylinder may be fixed to the bottom of the drum or other vessel see
Fig. 1, or may be connected to the bung and form one self contained article
see Fig. 6.
Working in the cylinder is a piston B attached to tube Chaving a hole in
the same so that the liquid may pass out of cylinder A and up tube C which
passes up through the bung plate D. On the tube C at a suitable distance we
affix a collar E which regulates the upward stroke of piston B, so that the liquid
is enabled to flow through the holes or ports in cylinder A and to fill same.
The top of tube (which passes through bung plate D is screwed for half the
length of coupling and when it is in the position as shown in Fig. 1 the
bottom of coupling F strikes the top of bung plate D and so regulates the down
stroke of the piston B. The tube is continued past coupling F by a short bent
tube G having two legs of unequal length each end of the legs being screwed a
greater distance than the length of coupling F, so that when in use for pumping
liquid see Fig. 1 the long leg is screwed into the remaining half of coupling F,
and the short leg stands some distance above the drum or other vessel in a posi-
tion either over the drum or turned away from same.
When the pump is not in use the long leg of bent tube G is screwed into a
coupling H fixed level with the top of drum or other vessel (which acts as vent
when in use Fig. 1) and the coupling is screwed its full length on to the short
leg of bent tube G; the whole is then screwed down into coupling H until the
end of short leg of bent tube G comes flush with the top of tube C, the coup-
ling F is then screwed down on to tube C and comes tightly on to top of bung D
forming a joint by means of leather or other washer see Fig. 3. The bent tube G
then forming a handle to facilitate the moving of the vessel.
The bung which works in connection with the pump consists principally of a
flat plate 1 having a projection on its under-side which fits the hole made in
the top of the drum or other vessel, this being of such size that access for clean-
ing is easily accomplished. A hole is made in the centro of bung plate D
through which the tube C slides. The bung plate D has two or more concen-
tric strips K (three are shown on the drawings annexed) the length of each of
which on the circumferential line is slightly less than the circumferential dis-
tance between the clamps I, which are secured to the top of drum so that the
bung may when desired be lifted free from the aforesaid clamps I see Fig. 4.
The clamps I the top parts of which come over the concentric strips K on the
bung are made with an inclined plane on the underside so that the plate and
strips when turned on the centre point for which lugs or projections J are pro-
vided on the plate wedge themselves against the same, under the plate we place
a leather or other washer which makes a joint on the top of drum. We might
also make the inclined plane on the plate and leave the clamp level see Fig. 6
which would have the same effect, that is the tightening of the piate on the top
of drum. If a metal joint is required we may secure a ring having a coned seat
on to the top of drum and the bottom projection on bung D would likewise he
coned; the concentric strips and clamps being the same as before a metal tight
joint would be made, when the bung was turned.
We may also invert the arrangement and make the clamps I part of the bung

page_text: plate D and have the concentric strips K attached to, or part of the bottle,
decanter or vessel see Fig. 7 and the incline may be either on the strips or the
clamps as before stated.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is ;-
1. In a drum or other vessel containing liquids, a combined, or otherwise pump
and bung, the combination of a pump consisting of a cylinder with ports and a
piston having an opening to the outlet tube, passing up through the bung and
without valves, for the purpose of raising liquid from the vessel.
2. In a drum or other vessel containing liquids, the combination of a bent
tube having two unequal legs attached to the top of the main tube, firstly for
the purpose of forming a handle and spout, for raising the liquid and secondly
for the purpose when reversed of forming a handle to facilitate the moving of
the vessel, and to form air tight joints at the vent hole and bung.
3. In a drum or other vessel containing liquids the combination of a bung plate
and clamps of such size as to allow easy access to the inside of vessel and also
to close the hole in the drum and at the same time to be a guide for the pump
tube.
4. A combined pump and bung constructed and operated substantially as des-
cribed and illustrated by annexed drawings.
