We GEORGE SMITH, 36 Gosforth Street, Monkwearmouth, Sunderland, in the
County of Durham, Machinist, and WILLIAM HEROD, Stoney Lane Southwick
Sunderland in the County of Durham Gardener do hereby declare the nature of this
invention to be as follows:-
Our Invention relates to a device for raising, drawing, conveying, and propelling
of Liquids, as Water, Oils, &c., from Wells, Tanks, Ships-holds, Reservoirs and other
similar uses, at Breweries, Dry-docks, Coffer-dams, Water-works, Pit-shafts, &c.,
through, or by means of a suitable pipe, cylinder, or tube.
The Invention essentially consists of two acting Valve Buckets, one being attached
to a hollow rod or tube, the other being connected to a solid rod or spear the latter
running internally and longitudinally through the former, having sufficient clearance
for working, and both being straight and parallel the one to the other, these working
simultaneously together, one descending to receive its supply, the other ascends to
discharge, hence the double character of its movement when in operation.

Machinist WILLIAM HEROD Stoney Lane Southwick Sunderland County of Durbain
Gardener, 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 :-
Our Invention relates to a device for drawing, lifting or raising, and propelling of
Liquids, as water, oils &c. and for other similar uses.
The invention essentially consists of a suitable barrel or pipe wherein are two acting
valve buckets with sliding tube which may be made of brass, the said barrel having a
side pocket or branch pipe cast on connecting the delivery side of the lower or interior
pump bucket, and the suction side of the upper or outside pump bucket, at the bottom
of which a weighted relief valve is fitted which acts in case of pressure.
The upper pump bucket is attached to a hollow rod or sliding tube by means of a
screw, and also having two rods one on either side of the sliding tube which being
parallel to it, are screwed into the crosshead of the valve guard or clam-plate, the

upper ends being secured to the crosshead by means of a screw and nut.
bucket is connected to a solid rod or spear screwed into it, the said rod passing
through the centre of the upper pump bucket, and running internally and longi-
tudinally through the sliding tube, surrounding this rod where it passes through the
centre of the upper pump bucket there is a gland screwed to or into the upper pump
bucket, whereby the air is excluded.
The two buckets working simultaneously in opposite directions, up and down, or
hither and thither as the case may be. The lower bucket when rising delivers its
quantity through the upper descending bucket into the well or receiver, from whence
it is discharged into the main or outlet. The upper one descending to receive its
supply, and when reversed. The now ascending upper bucket delivers its quantity at
the same time that the lower one is descending to lay hold of a fresh supply:-hence
the double character of the movement when in operation.

Having particularly described and ascertained the nature of the said invention and
the manner of performing the same we hereby declare that what we claim is :-
1st. The employment in combination of the sliding tube or hollow rod and the
upper pump bucket constructed arranged and applied substantially as and for the
purposes herein described and shown in the drawings.
2nd. The combination of the gland surrounding the lower bucket rod and the
upper pump bucket arranged and applied substantially as shown in letter K.
3rd. The employment in combination of the lower pump bucket rod and the sliding
tube or rod and the upper pump bucket and gland arranged and applied as shown in
the letters H. J. G. E. K.
4th. The employment in combination of the two rods L pump running parallel with
the sliding tube or rod and the upper bucket as shown in the letters F. F. G. E.
5th. The employment in combination with the working barrel or pipe and the side
pocket or branch pipe having relief valve constructed and applied as shown in the
letters B. and C.
6th. The employment in combination of the crosshead and the sliding tube and side
rods arranged as shown in the letter D.
7th. The employment in combination of the two pump buckets working simultaneously
in opposite directions arranged and applied as shown in the drawings.
In witness whereof we the said George Smith and William Herod have hereunto
set our hand this Twelfth day of October in the year of our Lord One thousand
Eight hundred and Eighty seven.
