Improvements in Garden Watering Cans.
I, GUILLERMO ANTONIO FARINI, of Dartmouth Lodge Perry Vale, Forest
Hill, in the County of Surrey, Gentleman 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:-
My invention relates to certain improvements in watering cans for gardening and
kindred purposes and has for its object the regulation of the flow of water, the
same being controlled by the person using the can by increasing or diminishing the
supply of air thereto.
In order that my said invention may be the better understood, I have appended
the accompanying sheet of drawings in which
Figure 1 is a sectional elevation of a watering can made in accordance with my
invention and
Figure 2 is an elevation of another type of can.
Figure 3 shows one method of securing hermeticity, and Figures 4 and 5 show
alternative methods.

Figures 6 and 7 are sectional views of parts of handles or hoops of cans, shewing
the air inlets.
As far as possible, similar letters of reference are used to indicate corresponding
parts throughout the several views.
In carrying my invention into effect I secure hermeticity by constructing the
mouth F tapering, with an internal annular groove m. A plug E with a ring or
like device k is covered externally by a sheath of india rubber, or like elastic
material so that when pressed into the tapering mouth F the elastic sheathing
aforesaid slightly expands into the groove m and makes a water and airtight joint.
Figure 5 shows this device, the sectional elevation being drawn to a larger scale,
and the plug E detached. Thus, after the can B is filled, it is easily closed by
pressing the plug E into the mouth F, and the only inlet for air is a small hole a
in the hollow handle or hoop A, preferably placed so as to be within reach of the
thumb or fingers of one hand of the person holding the can. Said can being held
in position for pouring, and being also hermetically sealed or closed as herein before
described, may be made to distribute the fluid contained therein at intervals
of time, and varying quantities as may be desired, by simply closing the orifice a
to stop the flow, and vice-versa, without altering the position of the can.
Referring to the appended drawings, the controlling device may be a simple
hole a Figure 6. in the handle or hoop A, or I may in some cases employ a reverse
valve or stop a, with a spiral spring and plunger or centre guide b, as shown by
Figure 7.
Figure 2 is an elevation of another form of can, with the same controlling device
as herein before described.
A
Figure 3 shows an alternative method of closing the mouth of the can, c.
cap or cover C is made to fit outside the mouth c loosely, and a handle or the
like K fitted thereto for free manipulation. A washer of india rubber or like
resilient or elastic substance is placed inside the cap C in such a manner as to be
compressed by the edge of the mouth c when said cap is in position. An inclined
plane d, which may be helical, is formed upon or is attached to the outside of the
mouth c, two or more being used, and oppositely placed with reference to each other.
Projections / upon the cover C engage therewith, and the washer is tightly

page_text: compressed by turning the cap C slightly in the direction of the inclination of the
projections d. Another alternative is shewn by Figure 4, where a screwed stopper
or cap g is used, the screw thread ff being cut away at eel, so that when placed
into the mouth of the can, which in this case is provided with an internal screw
thread similarly cut away, said cap may be pressed down and secured by a slight
turn. An elastic washer upon the mouth, or under the head of g may thus be
compressed and effect the desired hermeticity.
I do not confine myself to any particular method of, or means for, securing
hermeticity, but hold as the essential feature of my said invention the control of
the air supply to the water surface within the can by the same hand holding said
can, so that the amount of water poured, and the period of pouring may be
efficiently regulated by such means.
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 ;-
First. In an improved watering can for garden and other purposes, the
combination of an hermetically closed can, and air inlet under the control of the
hand of the person using said can, substantially as and for the purposes herein
set forth, with reference to the drawings.
Second. In an improved watering can for garden and other purposes, the
combination of a plug or cover, water vessel and spout, with an air inlet in the
handle or hoop, substantially as herein described and shewn by the drawings.
Dated this 10th day of June 1895.
