Improvements in Pumps.
I, LIONEL DE LAUTOUR WELLS, of the Metropolitan Fire Brigade Head Quarters,
Southwark, in the County of London, Commander in the Royal Navy, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to hand pumps such as are employed by fire-men
and others in extinguishing small outbreaks of fire. With such pumps as
ordinarily made it is practically impossible for one man to hold the suction end
of the pump barrel in a bucket of water, to actuate the pump bucket or piston and,
at the same time, to direct the jet of water, which is discharged through a short
length of hose that is attached to the outlet of the pump and is fitted with a
nozzle. It has previously been proposed to provide a folding canvas, bucket to
which a pump can be detachably connected by means of a bayonet joint, the
bucket being fitted with foot plates by standing on which the operator can hold
the bucket and connected pump barrel in place whilst actuating the pump
bucket or piston with one hand and directing the water jet with the other.
Such an arrangement is cumbrous and not easily got ready for use.
Now according to this invention, I provide the lower end of a pump, such as
an ordinary hand fire pump, with a pivoted or other stirrup or the like, by placing
his foot in which the fireman can hold down the pump barrel, and attach to the
pump barrel, below the inlet openings thereto, a collapsible bag of canvas, leather
or other suitable material, the arrangement being such that the pump occupies
a more or less central position in the bag, which, when open, can be filled with
water and serves as a reservoir for the pump, and which, when the pump is not
required for use, can be collapsed or closed around it after the manner of an
umbrella. The bag may be attached to ribs of metal, cane or the like, that are
arranged radially around and are jointed to the pump barrel and may also be
jointed at a convenient part of their length and formed with abutments to limit
their movements; the arrangement may be such that, when open, the bag will
form a vessel more or less cylindrical for the greater part of its length but with
a tapering or conical lower end.

page_text: declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:-
This invention has reference to hand pumps such as are employed by fire-men
and others in extinguishing small outbreaks of fire. With such pumps as
ordinarily made it is practically impossible for one man to hold the suction end
of the pump barrel in a bucket of water, to actuate the pump bucket or piston and,
at the same time, to direct the jet of water, which is discharged through a short
length of hose that is attached to the outlet of the pump and is fitted with a
nozzle. It has previously been proposed to provide a folding canvas bucket to
which a pump can be detachably connected by means of a bayonet joint,. the
bucket being fitted with foot plates by standing on which the operator can hold
the 'bucket and connected pump barrel in place whilst actuating the pump
bucket or piston with one hand and directing the water jet with the other.
Such an arrangement is cumbrous and not easily got ready for use.
Now according to this invention, I provide the lower end of a pump, such as
an ordinary hand fire pump, with a pivoted or other stirrup or the like, by placing
his foot in which the fireman can hold down the pump barrel, and attach to the
pump barrel, below the inlet openings thereto, a collapsible bag of canvas, leather
or other suitable material, the arrangement being such that the pump occupies
a more or less central position in the bag, which, when open, can be filled with
water and serves as a reservoir for the pump, and which, when the pump is not
required for use, can be collapsed or closed around it after the manner of an
umbrella.
it;
In the accompanying drawings such a construction of pump is illustrated.
Fig. 1 is an elevation thereof with its collapsible bag or reservoir closed around
Fig. 2 a sectional elevation thereof at right angles to Fig. 1, the bag or reservoir
being open and charged with water; and
Fig. 3 an underside view thereof with the bag or reservoir indicated by dotted
lines in its open position.
The pump barrel proper is contained within an outer casing 1 which forms the
delivery passage and to the upper end of which is connected a length of hose 2,
preferably covered with asbestos and which terminates in a nozzle 2. The lower
end of the casing 1 is fitted into a skeleton socket 3 formed with a screw that
screws into a stirrup 4; the stirrup also serves as a base or foot on which the
pump stands. 5 is a metal ring which is clamped between the stirrup and the
socket 3 to which are pivoted metal ribs 6; these ribs are jointed at 6" and their
pivoted ends are formed with abutments which bear against the ring 5 and limit
their downward movement when they are in a horizontal attitude. 7 is the canvas
bag or reservoir which is preferably formed with external pockets into which the
ribs 6 extend as shown; the bottom of the bag is formed with a central aperture
through which the screw 3" extends and the material around which is gripped
between the socket 3 and the ring 5. The lower end of the casing 1 is connected
to the socket 3 by a bayonet joint so as to rigidly connect the pump with its
stirrup 8 is a loose spring catch which is inserted in the groove (formed as part
of the bayonet joint) in the socket 3 to prevent the pump being accidentally
detached.
The pump piston rod is provided with a handle and with projections 9" which
can be caused by turning the handle to enter slots or grooves 10 formed in a
projecting flange of the guide ring 11; the slots or grooves 10 are formed with
upwardly extending inner portions (sce Fig. 2^) into which the projections 9"
take and thus prevent the piston rod moving lengthwise of the barrel, thereby
enabling the pump, with its bag or reservoir, either charged with water or not,
to be readily carried about. 12 is a strap attached to the bag by which it may be
secured in its closed position around the pump barrel as shown in Fig. 1.
As will be seen, the stirrup being directly beneath the pump it can be easily

page_text: held by the foot and there will be practically no tendency to tip the reservoir
when pumping, which can be readily done with one hand, whilst the jet from
the nozzle is directed by the other. Instead of the ribs 6 being of metal they
may be of other suitable material such as cane and the arrangement may be such
that, when open, the bag or reservoir will form a vessel more or less cylindrical
for the greater part of its length but with a tapering or conical lower end.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
A pump provided at its lower end with a holding down stirrup and with a
surrounding collapsible bag or reservoir having supporting ribs the pump being
more or less centrally arranged within the said bag or reservoir, substantially as
described and shown in the accompanying, drawings.
