Improvements in Hand Pumps for Garden Use, also Applicable to
other Purposes.
We THOMAS SIMPSON YORKE of 25 St. Giles Street, Northampton, Club Manager,
and WILLIAM GODFREY, of 3 Woburn Street, Northampton, Gas Fitter, do hereby
declare the nature of our invention to be as follows:-
Our invention is designed to provide a convenient form of hand pump for use in
Garden or small fire engines which is independent of the tank or receptacle for water
or liquid and is simply placed so as to stand therein when required for use, and is so
constructed to allow ready access to all the valves and other parts of the pump for the
purpose of cleaning repairing or adjusting.
Our invention is further designed to simplify adjustment of the plunger without
the necessity of repacking and also to provide a ready and effective method of using
the apparatus in a conservatory or otherwise for watering flowers and the like so as
to obviate the necessity of using the ordinary watering can or syringe.
In carrying out our invention we provide preferably a cylindrical tube, or pump
barrel of metal or other suitable material having cast or affixed to one-side thereof, a
second and smaller tube parallel or nearly so to the main tube and we bend or form
the top of this second and smaller tube in any convenient manner to enable the
delivery pipe or hose to be affixed thereto. The lower extremity of the second tube
communicates by means of a passage with the main tube or barrel said passage being
closed by means of a suitable valve or flap, opposite to which and in the second tube
we provide a hand hole with a suitable cover and fastenings to allow of access to the
valve or flap.
The lower extremity of the main tube or pump barrel is carried out to form a base
with feet, or orifices are provided for liquid to flow through or it may be flanged and
bolted to a separately formed base of suitable shape.
At this lower extremity of the main tube a bottom or floor is formed in which is
an orifice provided with a suitable valve through which the liquid enters the pump
and through which the hand may be inserted to regulate the plunger or for other
purposes.
The plunger is formed of two hollowed discs of C section placed back to back
thus and having between them a packing of india rubber or other elastic
material. The lower end of the plunger rod passes through these which are attached
therǝto in such a manner as will allow of the discs being adjusted by means of a
tightening screw and nut the discs expanding with the elastic packing when screwed
more tightly together.
A suitable cap is provided at the upper extremity of the pump barrel closely fitting
same and is provided with a suitably packed orifice through which the plunger rod
works, said rod being provided with a handle in the usual way. Outlets for air are
also formed.
To the end of the bent part of the second tube we may attach a pliable hose carrying
a nozzle to which may be affixed a watering rose or spreader or other convenient
device for delivering the liquid.
Dated this 3rd day of June 1889.

We THOMAS SIMPSON YORKE of 25 St. Giles Street Northampton Club Manager
and WILLIAM GODFREY of 3 Woburn Street Northampton Gas. Fitter 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 is designed to provide a convenient form of hand pump for use in
Garden or small fire engines which is independent of the tank or receptacle for water
or liquid and is simply placed so as to stand therein when required for use and is so
constructed as to allow ready access to all the valves and other parts of the pump for
the purpose of cleaning repairing or adjusting.
Our invention is further designed to simplify adjustment of the plunger without
the necessity of repacking and also to provide a ready and effective method of using
the apparatus in a conservatory or otherwise for watering flowers and, the like so as
to obviate the necessity of using the ordinary watering can and syringe.
Referring to the accompanying drawings and to the letters of reference marked
thereon.
Figure 1 is a sectional elevation of our pump or engine.
Figure 2 is a view of an attachment we prefer to employ for use in conservatories
and for watering flowers, plants and the like.
In carrying out our invention we provide preferably a cylindrical tube or pump
barrel A of metal or other suitable material having cast or affixed to one side thereof
a second and smaller tube B parallel or nearly so to the main tube and we bend or
form the top of this second and smaller tube in any convenient manner to enable the
delivery pipe or hose C to be affixed thereto.
The lower extremity of this second tube communicates by means of a passage D
with the main tube or barrel A said passage being closed by a suitable valve or flap E
opposite to which and in the second tube we provide a hand hole with a suitable cover
and fastening F to allow of access to the valve or flap E.
The lower extremity of the main tube or pump barrel is carried out to form a base G
with feet; orifices a are provided for liquid to flow through or it may be flanged and
bolted to a separately formed base of suitable shape.
At this lower extremity of the main tube a bottom or floor H is formed in which
is an orifice provided with a suitable valve I through which the liquid enters the
pump and through which the hand may. be inserted to regulate the plunger J or for
other purposes.
The plunger J is formed of two hollowed discs of C section placed back to back
thus and having between them a packing of indiarubber or other suitable
material. The lower end of the plunger rod K passes through these which are
attached thereto in such a manner as will allow of the discs being adjusted by means
of a tightening screw and nut L the discs expanding with the elastic packing when
screwed more tightly together. A suitable cap M is provided at the upper extremity
of the pump barrel closely fitting sanie and is provided with a suitably packed orifice
through which the plunger rod K works, said rod being provided with a handle N
in the usual way. Outlets 6 for air are also provided and an overflow O may be fixed
if desired.
To the end of the bent part of the second tube B we may attach a pliable hose
carrying a nozzle to which may be affixed a watering rose or spreader or other
convenient device for delivering the liquid.

page_text: 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 :-
First In a pump or engine as hereinbefore described the employment of a
plunger composed of two or more concave pieces of metal or other suitable material
placed back to back and between which is placed a packing, said packing being
expanded by the compression of the two concave pieces of metal or other material
by means of a nut or screw substantially as herein described.
Second-The general arrangement and combination of parts constituting our
improved pump or engine substantially as herein described and illustrated in the
accompanying drawings.
