WILLIAM FRASER Engineer 49 Oxford Road Finsbury Park London N. do hereby
declare the nature of this invention to be as follows:-
The barrel of the Pump is made about 2" in diar. or thereby & about 6" long &
stands perpendicular in a wood or galvanised box about 6" high & about 12" by 16"
or thereby. The barrel is fixed to the top & bottom of the box by means of plates
& screws or otherwise the top end having a stuffing box. The plunger is a piece of
tube about 4" long or thereby, with two valves at each end 1.E. a valve at each end
to admit the water & one at each end for its escape. The barrel of the pump has a
slot about 1" long & about " wide at each side about half way down the barrel.
The plunger has a half inch hole at each side also, into which a nipple is screwed at
each side. 1.E. the nipples are screwed into the plunger after being placed in the
barrel & stands exactly opposite one another, but at opposite sides. The suction pipe
The
is attached to the right hand one & the delivery pipe to the left hand one.
nipples are each about 1" long & works up & down in the slots in the barrel of the
pump. The plunger is divided into two compartments each one being all the length
of the plunger. The suction pipe being attached by means of the nipple on the right
hand compartment, the delivery pipe being attached in like manner to the left hand
compartment, each compartment having two valves one at each end, the two in the
right hand compartment admitting the water. The two in the left hand compartment
discharging it. The piston rod of the plunger passes thro the top side of the box &
is about 2" long or thereby there is a spiral spring placed in the bottom of the barrel
about 24" long & gives the plunger the back stroke. I.E. when the pump is to be
used the suction pipe will draw from any pale or sistern the delivery pipe is held by
any of the hands or both by then standing on the top of the box which stands about
6" high & quite broad & long enought to do so by then placing the foot on a foot-
board which is hinged at the toe end. The heel end resting upon the piston of the
pump, by sending this board down with the heel the plunger is thus sent down the
same stroke compressing the spring at the bottom end of the plunger. Thus the down

page_text: stroke of the pump is made by the foot & the up stroke by the spring. L.E. if 50 lbs.
of pressure was wanted by placing 100 lbs. pressure or weight upon the foot board &
then removing same after the plunger had been sent down the spring being the
necessary strength required forces the plunger up again so to get a double stroke of
the pump at 50 lbs. pressure one push of double the pressure required must be given
to the foot board, by simply putting your weight upon the board & removing or
releasing same the moment the plunger is sent home. Thus the pump can be wrought
by the heel & a continuous flow obtained. The delivery pipe can be held by either
hand leaving the person working the pump with a hand free for any other purpose,
a small air chamber is placed inside the box & attached by a flexable piece of tube
to the delivery nipple thus making the continuous flow of water more perfect. The
box has a hinged cover on the top of it. The suction & delivery pipes being attached
to the nipples at each side resply. passes thro each end of the box directly opposite
the slots in the barrel & when not in use can be coiled up & put into the box (the
.other ends being permently fixed to the nipples) & the cover closed thus making a very
compact arrangement & weighing only about 10 or 12 lbs. The box in the drawing is
marked A. Suction & delivery pipes B & C resply.

purposes or for washing windows or can be fixed to the floor of any place for pumping
beer or the like.
The pump is most applicable for washing & cleaning windows as a continuous
stream of water can be thrown forty feet over head & with great force, the pump
being wrought by the foot in the manner already described.

I, WILLIAM FRASER of 49 Oxford Road, Finsbury Park, London N. Engineer,
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:
This invention relates to pumps or apparatus, as herein-after described, for raising,
forcing, and throwing water for various purposes.
Figure 1 represents in side elevation, a double action force pump, constructed in
accordance with my invention.
Figure 2 represents a complete vertical section of the said figure 1, but taken at
right angles thereto, and upon the dotted lines A B.
Figure 3 is a horizontal section, upon the lines CD figure 1, showing the base in
elevation.
Figure 4 represents a side elevation of the divisioned hollow plunger, exhibiting
the open side, wherethrough water from the suction pipe, inwardly passes.
Figure 5 represents a complete vertical section of the said plunger, but at right
angles to that shown at figure 4.
Figure 6 is a top side view of the said plunger, and figure 7 is an underside view
of the same, while figure 8 is a transverse section upon the dotted lines E F figure 5,
looking from above.
The same letters of reference indicate corresponding parts in the several figures of
the drawings.
a is the barrel of the pump, closed at top and bottom, and having working within
it, a hollow plunger b, partitioned or divided off into two compartments c and d. The
compartiment c, is provided with a longitudinal slot or opening c², wherethrough
water from the said plunger, outwardly passes through the delivery pipe e, while the
outside of the compartment d, of the said plunger, has also a longitudinal slot, where-
through water enters to the plunger, through the suction pipe f, whose nipple bas
upon it, a flexible hose f2, leading to a water tank or other vessel, from whence liquid
to be raised or thrown, is drawn by suction.
The plunger is provided with two upper and two lower valves, marked respectively
c, c, d, d. The valves d³ d, are in connection with the compartment a, which
is in direct communication with the suction pipe, while the compartment c, has inlet
and outlet valves c³, c, both of which open inwardly, while the valves d³, d, of the
other compartment d, which has channels d³, running from it, open outwardly.
is a plunger rod, working through a stuffing box a², in the upper part of the
barrel a, and has at its summit, an underside flanged disc a³, for holding in position
the top end of the coiled spring h, which partially encircles both barrel and plunger
rod.

page_text: The lower end of the coiled spring, seats itself upon a rest a³, surrounding the
barrel at the junction of it, with the suction and delivery passages.
The extreme summit of the plunger rod, carries a cap g, upon which the underside
of the operating lever i, fulcrumed at 2, presses itself, on the lowering of the lever,
by a foot placed within the swinging stirrup j, whose foot plate 3, is at its lower
end.
The lever i, is supported upon an upright or standard k, resting upon a base
plate k³.
The lower end of the barrel a, below the suction and outlet passages, is surrounded
by a cylinder, which constitutes an air chamber, for producing continuous flow of
liquid, through the outlet pipe, on the momentary change of stroke occuring; com-
munication between the outlet pipe, which has a flexible hose upon its nipple, is made
by a depending tube m, down which water passes, and the necessary pressure there-
through, exerted by the compressed air in the interior of the said chamber.
It will be observed, that the plunger is lowered within its cylinder, by the pressure
of the foot, while the same is raised by the pressure exerted by the spring, after
compression. Thus, the plunger has its backward stroke given to it, and the parts
taken back to their normal positions as represented in figure 1, by the opening out of
the spring, which was previously compressed, by the down stroke.
The plunger is provided with cup leathers n, at top and bottom, but it is obvious
that any other suitable packing may be used, or a plunger without packing at all.
The pump is operated, as follows:-
The foot is placed in the stirrup 1, 2, and the lever i, forced downwardly, and
turned upon its joint ², thereby compressing the plunger rod 92 and giving the
plunger its downstroke, which causes the liquid enclosed under the piston, to be forced
through the valve opening of the valve c³, into the chamber c, and out through the
slot c, and thence to the delivery pipe e, to a hose or other pipe in connection there-
with. The flowing of liquid into the chamber c, closes the valve c, at the upper end
of piston and chamber c, while the spring his also compressed.
The down stroke as aforesaid, creates a vacuum in the upper end of the barrel
above the plunger, and so the valve d', opens, and through the passage which it covers,
liquid is drawn through the chamber d, from the suction pipe f; so that on the
plunger completing its down stroke, the upper interior of the barrel above the plunger,
is filled with liquid.
By releasing pressure of the foot upon the stirrup, which is limited by a stop i³,
the spring expands itself, and gives the return stroke to the plunger, which in its
upward motion, closes the valve d*, and opens the valve c', wherethrough the valve
passage of the latter, liquid flows to the chamber c, and from thence through its
gapped side c², to the delivery pipe e. The said upward stroke of the plunger, closes
the valve c³, and opens the valve d³, so that liquid is now drawn under the plunger,
ready for its next stroke, to be expelled as aforesaid.
A constant flow is kept up, by the compressed air enclosed within the upper part of
the cylinder, acting upon a stratum of water in the said cylinder, being forced up
the depending pipe n, leading into the orifice of the delivery pipe.
The lever i, is made adjustable, by the pin-holes, so that by changing the joint
centre, to one or other of the holes, the lever can be lengthened or shortened, so as to
acquire greater or less power.
The barrel of the pump, can be slotted or gapped, instead of the plunger, and the
suction and delivery pipes or nipples, attached (screwed) to the plunger, instead of to
the barrel.
Instead of the valves as represented other forms may be employed.
The spring can be applied above or below the plunger, outside or inside the
barrel.
The air chamber, could be got or obtained, by utilizing the spare space, inside the
plunger, that is, only leaving a through water way about " in diameter, at each side
respectively, of the plunger, from end to end, and utilizing the remaining space,
as an air chamber, and trapping the air in a similar manner, to that already shown.

page_text: The pump can be fitted on a box, of any kind of material, and with the bottom end
of the said pump, resting upon the inside of box, while the top end would project
through the top side, sufficiently, to give the necessary throw to the pump; then by
standing on the top of the box, the pump could be worked, by either causing pressure
direct upon the top end of the piston rod of the plunger, or by having a suitable lever,
for placing the foot in (or upon it) hinged to the box at one end, the other end working
up and down, with the piston and spring.
A pair of pumps could be worked upon this principle, by simply standing first on
one, and then the other; that is, putting first, the weight of the body on one lever,
then upon the other, the springs in both pumps, giving the return strokes..
The box of the pump so fitted, could be utilized for holding water, and the pump
or pumps, may be made to draw their supply from the same. The pump or pumps in
this box, could be fitted with a lever and stirrup, and worked by standing on the
ground, and not on the top of the box.
The pumps could if necessary, be worked by means of a spring-board, arranged
immediately above the piston rod, which may be attached to same; that is, the board
could be fitted with a spring or springs, of sufficient strength, to give the pump or
pumps, the back or return stroke.
The plunger can be fitted with any kind of metallic rings or packing, or the cup
leathers may be dispensed with.
Having now particularly described' and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First. Giving the back or returned stroke, to the plunger or piston, of a pump, or
other liquid raiser or thrower, by a coil spring or its equivalent, either outside, or
inside the barrel, above or below the plunger, as set forth.
Secondly. A hollow plunger, divided off into compartments c, d, and respectively
provided with gaps and valves c³, c³, c¹, d², d³, d, or their equivalents, substantially as
set forth.
Thirdly. The combination with a barrel a, and hollow plunger, with compart
ments c, d, of an air chamber 1, and suction and delivery passages e, f, as described
and set forth.
Fourthly. The combination with the barrel a, and air chamber 1, of a delivery pipe,
and depending pressure tube m, as set forth.
Fifthly. The improvements in pumps, syringes, or other water, or liquid forcing
and raising means, as set forth; and the parts of which said apparatus or appa-
ratuses, is or are constructed, arranged, and work, substantially as described and
illustrated.
