I, JOHN LECKIE, Manor Crescent Gourock in the county of Renfrew, Scotland,
Clerk, do hereby declare the nature of my invention for QUADRUPLE ACTION LIFT
AND FORCE PUMPS to be as follows:-
My invention relates to a construction of pump, simple, compact, economical in
space as well as in cost capable of lifting and discharging or forcing continuously with
small expenditure of power a constant and very large volume of water.
Placed vertically alongside each other a few inches apart are two chambers
connected together at bottom by a flanged or junction piece.
Chambers are close or plug ended at top
to bottom end of chamber on right hand
chamber. A similar attachment connects
hand.
Top end of chamber on left is connected
side by a pipe about half diameter of
chamber on right to chamber on left
An orifice is formed near centre of each chamber into which a crank fixed on to a
straight shaft moves in and out when actuated by handles attached' to shaft aforesaid.
This orice is enclosed all round, and the box or cavity formed by such enclosure
forms pump head, into which water from chamber is discharged and from thence runs
off by a nozzle fixed conveniently therein.
A three wayed branch pipe or underseat connects with both chambers at bottom, to
main or bottoin branch of underseat is connected suction pipe of pump.
Valves are mounted upon material forming joint between flanges connecting
chambers to underseat, for regulating inflow of water into chambers.
A strong spiral spring may be placed in upper end of chambers to act in a downward
direction upon end of pump buckets which will be placed in chambers immediately
below spring aforesaid, and kept pressing against spring upwardly by extremities of
crank already mentioned.
Buckets or plungers are of peculiar construction, upper end or half forming a solid
plunger or piston, suitably packed, while lower end (which is divided from upper end
by a groove or slot running through centre of length about half way) is what is

page_text: known as an open bucket or pump box having valve for allowing water to pass
through upon down stroke, and closing upon return stroke being administered. Solid
plugs are cast in bottom end of upper half of plungers and upper end of lower half of
plungers against which plugs or surfaces crank presses raising and depressing buckets
in chambers when actuated from without by handles or levers fixed on to shaft
aforesaid, a vacuum thereby being created simultaneously in upper portion of left
chamber with lower portion of right chamber, and an ejectory impetus is com-
municated to water in upper portion of right chamber and lower portion of left
chamber at the same time and by the same means.

page_text: I, JOHN LECKIE, Manor Crescent, Gourock in the county of Renfrew, Scotland,
Clerk, do hereby declare the nature of my invention for QUADRUPLE ACTION LIFT
AND FORCE PUMPS 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 a construction of pump simple, compact, economical of
space as well as cost, capable of lifting and discharging or forcing continuously, with
small expenditure of force or power, a constant and large volume of water.
Figure I of the accompanying drawings is a vertical section of a pump according to
my invention. A, A", are the barrels or chambers which are connected at bottom to
underseat B. to bottom or main branch of which is connected tail or suction pipe of
pump, the two lateral branches being for the purpose of dividing and delivering the
water raised, into each chamber. Between these parts are the inlet or induction
valves C, C, opening upwards into chambers A, A.
Alongside, and running parallel with chambers A, A, are side passages or branch
pipes D, Dd, side passage D' communicating with upper and lower parts of chambers A
at bottom, and upper part of chamber A a at top only, whereas side passage D d
communicates with upper and lower parts of chambers A a at bottom and upper part
of chamber A at top only. Figure 2 of drawings shews mode of communication
between side passages and chambers at top end of pump. Space between upper and:
lower parts of chambers A and A a is enclosed all round forming head of pump
marked E on drawing, front or face of head being loose to admit of access being had
to same when necessary. Passing through head E is a straight spindle or shaft F.
made watertight where it passes through front or back, or through both front and
back of head E by means of packing glands or nuts. Keyed, or, otherwise fixed on
to centre of shaft F is a crossbar or beam G having cam at each end (fixed or loose)
while outside of head E handles, levers, or cranks may be attached to spindle or
shaft F for actuating same
Discharge nozzle H may be placed on back or front, or on both back and front of
head E.
Within upper parts of chambers A and A a pistons I and I i work respectively,
while in lower parts of chambers aforesaid buckets J and Jj (having valves opening
only as buckets descend) work respectively. Pistons and buckets are constructed in
one piece and have an eyepiece or socket K and Kk formed in centre, into which
cams at ends of crossbar or beam G fit exactly. Where piston rods II and ii pass
through roof of pump head E into upper parts of chambers A and A a respectively,
the roof of pump head is made air and watertight by means of packing nuts L
and L. Lower parts of chambers A and A a open into pump head E as shewn on
drawing.

page_text: A door may be placed on lower part of chambers A and A a for access being had to
inlet valves C and Cc when necessity exists.
On the handles or cranks attached to shaft F being raised and depressed the cams
at extremities of beam G press upon bottom and top of socket or eyepieces K and K k
in combined pistons and buckets, forcing them up and down alternately in chambers.
Upon the ascent of combined piston and bucket I J, the water by the opening of inlet
valve C passes into lower part of chamber A filling up the space between bucket J
and inlet valve C, into upper part of chamber A below piston I through side passage D,
and the descent of combined piston and bucket I, J, having taken place at the same
moment, a flow of water also takes place through the same channel into the upper
part of chamber A a above piston I i. Upon the ascent of combined piston and
bucket Ii Jj the water by the opening of inlet valve (e passes into lower part of
chamber A a filling up the space between bucket J ; and inlet valvo Cc, into upper
part of chamber A a below piston I through side passage D d, and the descent of
combined piston and bucket I J having taken place at the same moment, a flow of
water also takes place through the same channel into the upper part of chamber A
above piston I.
By the ascent of combined piston and bucket Ii Jj the water contained in upper
part of chamber A a above piston I i is forced through side passage D at the same
moment that by the descent of combined piston and bucket IJ the water in upper
part of chamber A below piston I is forced through the same channel into lower part
of chamber A, the valve on bucket J opening and allowing the water from the parts
mentioned, as well as the water contained in lower part of chamber A between
bucket J and inlet valve C (the latter closing immediately combined piston and
bucket IJ begins to descenci, and combined piston and bucket Ii Jj to ascend) to
pass through into head E and from thence through nozzle H into the open air.
By the ascent of combined piston and bucket IJ the water contained in upper part
of chamber A above piston J. is forced through side passage D d at the same moment
that by the descent of combined piston and bucket Ii Jj the water in upper part of
chamber A a below piston Ii is forced through the same channel into lower part of
chamber A a, the valve on bucket J j opening and allowing the water from the
parts mentioned, as well as the water contained in lower part of chamber A a, between
bucket J and inlet valve Ce (the latter closing immediately combined piston and
bucket IJ begins to descend, and combined piston and bucket 1 J to ascend) to
pass through into head E, and from thence through nozzle H into the open air.
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
1. A pump constructed, combined, and operating substantially as herein described
in reference to the accompanying drawings.
2. In a pump, a beam or cross bar having cams or castors on extremities, working
in a hollow socket or eyepiece, and oscillated by a central shaft, or on a central
pivot.
3. In a pump, combined pistons and buckets, having hollow socket or eyepiece in
centre, all' as described in reference to drawings figures 1 and 3.
