Improvements in or relating to Portable Pumping Apparatus.
We, DONALD NOBLE, and JOHN ARTHUR BROWN, of The Nobro Works, Little
Queen Street, Leeds, in the County of York, Engineers, do hereby declare the
ature of this invention to be as follows:-
This invention relates to a simple arrangement of portable pumping apparatus
capable of being attached to the leg of the operator, and worked by the foot.
The pumping apparatus may also, if desired, be mounted upon a suitable stand and
operated by the foot by means of any convenient stirrup or lever arrangement.
According to this invention in its simplest form, and the form we prefer
employing, consists of any convenient diameter and length provided with one or
more covers and divided into three compartments to form a spring compartment,
the pump barrel, and an air vessel. The pump barrel is preferably, though not
necessarily so, arranged between the spring compartment and the air vessel; but if
desired the air vessel might be arranged separately at the side of but in connection
with the pump barrel. In the pump barrel is arranged a piston, the rod of which
passes through the spring compartment and projects beyond the lower end of the
tube. The outer end of the pump rod is armed or provided with an enlarged base.
A suitable helical or other spring is arranged within the spring compartment and
connected to the piston rod for returning the piston to the bottom of the pump
barrel. To the tube is fixed and combined therewith in any suitable manner a
valve box containing any suitable arrangement of valves for regulating and
controlling the inlet and outlet of water to the pump barrel. Suitable clips alone,
or clips and straps combined, as well as rests or projections and straps or their
equivalents for the operator's foot or heel are provided on or fixed to the tube for
respectively, attaching the apparatus to the operator's leg, and for reciprocating
the piston. When a stirrup arrangement is employed it may be fixed directly to
the piston rod.
The pumping apparatus may be connected with any suitable water receptacle,
and with a self-feeding water brush, or its equivalent, by means of india rubber
tubes (armed with suitable fittings) attached respectively to the valve box and the
air vessel.
Provision is also made for throwing the piston in and out of action without
detaching it from the operator's leg.
Portable pumping apparatus constructed as above described is particularly
applicable for watering, sprinkling, and cleansing purposes, say in combination with
a bucket or other water receptacle carried from place to place, as for instance in
window or carriage washing or cleansing.

Improvements in or relating to Portable Pumping Apparatus.
We,
DONALD NOBLE, and JOHN ARTHUR BROWN, of The Nobro Works, Little
Queen Street, Leeds, in the County: of York, Engineers, 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 a simple arrangement of portable pumping apparatus
capable of being attached to the leg of the operator and worked by the foot. The
pumping apparatus may be operated by the foot by means of any convenient stirrup
fixed to a tube strapped to the back of the leg.
Portable pumping apparatus constructed as herein described is particularly
applicable for watering, sprinkling, and cleansing purposes, say in combination with
a bucket or other water receptacle carried from place to place as for window or
carriage washing or cleansing.

Figs. 13 and 14 are an elevation and a plan of clip at the top of pump barrel.
Like parts in all the views are marked with the same letters of reference.
According to this invention in its simplest form, and the form we prefer
employing, consists of a tube or barrel of any convenient diameter and length, say
one and three quarters inches in diameter and fifteens inches long, provided with
one or more covers a, a', two are shown in the drawings. The barrel is divided
into three compartments by means of division plates a², a², to form a spring
compartment A, the pump barrel A', and an air vessel A². The pump barrel A,
'is preferably, though not necessarily so, arranged between the spring compartment A
and the air vessel A2, but if desired the air vessel might be arranged separately at
the side of, but in connection, with the pump barrel. In the pump barrel A is
arranged a piston B, the rod B₁ of which passes through the spring compartment A
and projects beyond the lower cover a¹ of the spring compartment A. The piston B
is formed of two plates bb, held together by the pin and nut 62. Between the
plates b, b, is inserted a flat circular spring around which is placed a wrapping
or packing of asbestos 6, hemp, or its equivalent. The piston rod B¹ may, if
desired, be made of a piece of tube provided with solid ends soldered or otherwise
fixed within the tube.
The outer end of the piston rod B' is armed or provided with an enlarged
base, consisting of the cup & armed with a leather or other washer screwed to
the lower end of the piston rod. A suitable helical or other spring C is arranged
within the spring compartment A around the piston rod for returning the piston to
the bottom of the pump barrel A'. The ends of the spring C are made to bear
against the underside of the division plate a³, and against a projection D soldered
or otherwise fixed to the piston rod. To the pump barrel is fixed and combined
therewith in any suitable manner a valve box, such as shown at E, containing any
suitable arrangement of valves, for regulating and controlling the inlet and outlet
of water to and from the pump barrel.

page_text: the valve box E is mounted a ball valve e, the
in e. The valve e controls the inlet of the water through passage e to which
let tube F is secured or otherwise fixed. An opening for the passage of water
the valve chamber E to the pump barrel A' is provided at e³. The outlet
e e' is arranged within the air vessel A2, the division plate a² being perforated
own and made to form the valve seat. This valve is prevented from rising
high by means of the bell mouth tube G which passes nearly to the bottom of
air vessel as shown. The tube G is also perforated at g to permit of the water
ering the air chamber. The water on entering the air chamber compresses the
and the pressure thereof provides a regular and constant supply.
Suitable clips alone, or clips H H' and straps I combined as shown in the
wings, as well as a rest or stirrup J and a heel back guard or metal strap K (or
eir equivalents) are provided for operator's heel, and the stirrup J. and strap K are
nted to the clip or fixing H', fixed to the lower portion of the outer portion of
e barrel forming the spring compartment, for respectively attaching the apparatus
the operator's leg and for reciprocating the piston.
The pumping apparatus may be connected with any suitable water receptacle,
ad with a self feeding water brush or it equivalent, by means of india rubber
abes, such as inlet tube F and outlet tube M (armed with suitable fittings) attached
espectively to the valve box E, and to elbow gl of the tube G, which passes through
he air vessel.
Provision is also made for throwing the piston in and out of action without.
detaching it from the operator's leg, such as for instance, by means of a similar
arrangement to a bayonet joint, consisting of the vertical slot L formed in the
spring compartment portion of the barrel in which slot works the pin d, formed on:
and projecting from the boss D. When it is desired to throw the pump out of
action, the piston B is forced to the top of the compartment A' by the operator
resting the weight of his body on the heel and turning the foot and leg slightly to
the right hand, the base of the piston rod then forming the pivot, the pin d will
then be carried into the horizontal or catch portion of the slot L, thereby tightly
holding the piston and rod in their highest, or in-position, so that the operator can
walk about with the pump strapped to his leg.
The mode of operation
as follows:-
fastened to the operator's leg with the barrel at the back
The pump barrel
5 thereof. The heel, say, of the right foot having been placed in the stirrup J with
the back of the heel in contact with the metal strap K, and the leg within the
upper clip H, the pump is then secured by the straps I to the leg. The strap
attached to the stirrup and lower clip H' is arranged to be passed over the instep
of the foot. By slightly depressing and turning the leg and foot (when the heel is
in
40 near the ground,-the base of the piston rod forming the pivot) to the left hand,
the pin d will be moved out of the horizontal slot 7 to permit of the spring C to
act upon
the boss D for bringing the piston B from the in-position to the bottom a²
of the pump barrel. The pump barrel is then caused to be raised, that
direction of arrow 1 by spring C. expanding which raises the barrel, and by means
45 of the stirrup J raises the heel of the operator's foot, the toe or forepart of the
foot remaining on the ground to form the pivot. Whenever the pump barrel is
raised, valve e is opened (valve e closed) and water drawn from the bucket o
other receptacle through inlet tube F into valve chamber E and from thenc
through aperture e³, into pump barrel A'. It will be readily understood that th
50 piston remains stationary during the ejection of the water whilst the pump barre
reciprocates or is being depressed.
On the depression of the heel, valve e will be closed and valve e, opened for allowin
the water in compartment or pump barrel A' to be passed through aperture
into the air vessel A2, and from thence through tubes G and M. to the self feedi
55 brush or other armature on the outlet end of tube M for ejection of water on
the article or other object to be washed or cleansed. The above described oper
tions may be repeated as often as desired and the piston again fixed in the in-posit

page_text: (and released therefrom) by a mere twist of the leg and foot as previously described
when the operator can walk to the desired position for again commencing the
pumping and washing operations.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1st. A pump adapted to be strapped to the leg and worked by the heel, the
forepart of the foot forming the pivot, substantially as herein set forth and
illustrated.
2nd. In a pump adapted to be strapped to the leg and worked by the heel,-the
forepart of the foot forming the pivot, the fixing of the piston in, and releasing
