Improvements in Nozzles for Garden Syringes and the like.
I, EDWARD ALBERT WHITE, of Beltring, Paddock Wood, in the County of
Kent, 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:-
This invention relates to improvements in nozzles for garden syringes and the
like, and it consists mainly in constructing same in such a manner as to enable
a filling valve to be employed in combination with a central plug by means of
which the water is caused to issue from the outlet orifice of the nozzle in the
form of a spray or in a state of fine division.
The invention is illustrated in the accompanying drawing, in which
Fig. 1 is a side elevation, and
Fig. 2 a plan view of a nozzle constructed according, to my invention.
Fig. 3 is a vertical section, and
Fig. 4 a horizontal cross section on the line 4-4 of Fig 3.
In carrying out my invention I make the nozzle A of conical form, same being
provided at its lower end with a screw thread a or other suitable means by
which it can be attached to the body of the syringe. At its upper end a small
orifice is made, through which the liquid is forced by operating the piston
of the syringe in the usual manner.
On the side of the nozzle A near the base of the cone, a small tubular inlet
branch B opening into the interior of the former is provided, same being made
with a valve seat at its outer end, against which a valve C (preferably hollow
and of comical form) is adapted to seat itself. Such valve C fits loosely in the
tubular branch B, and is prevented leaving the latter by a bar & extending across
the interior of the tube, or by any other suitable means.
To effect the distribution of the liquid in the form of a spray I insert in the
body of the nozzle a plug 1, leaving a space E between the end of the latter and
the end of the nozzle in which the orifice a¹ is formed, and I connect such space E
with the main body of the nozzle by one or more (preferably two) grooves or
waterways of helical or other form, provided on the periphery of or formed
through the plug. By changing the direction of these grooves or by altering
the position of the plug in the nozzle the form of spray produced may be varied,
and to enable this to be readily done either by substituting a plug with grooves
of a different character to those in the one in use. or altering the position of
the plug in the nozzle, I prefer to make such plugs with extensions d'which can
be grasped by the fingers, when the plug can be unscrewed and removed and a
different one substituted, or its position in the nozzle be adjusted.
The operation of the arrangement is as follows:-
When the syringe provided with the improved nozzle is to be used the nozzle
is inserted in the liquid from which the supply is to be taken, and the piston
drawn outwards in the usual manner. The effect of this will be to draw the
valve C from its seat b thus permitting the liquid to enter the syringe around such

page_text: valve, and so greatly facilitating the filling of the former. When the syringe is
being discharged the water entering will force the valve C onto its seat, thus
closing the opening by which the liquid entered, so that such liquid will be
driven through the grooves F in plug 1 into space E, and thence through the
small orifice a in the form of spray.
I find it preferable to provide the end of the tubular branch B with a cap or
cover G of perforated metal or wire gauze, which will not allow any leaves or
other substances in the liquid from which the supply is taken to enter such
opening, and thereby prevent the valve C from fitting its seat properly when the
syringe is being discharged, but the improved nozzle may be used without such
cap or cover if desired.
'
It will be readily understood that the cap or cover G above described might be
applied to inlet branches of syringes of different construction to that. above
described.
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:
1 A nozzle of conical form for garden syringes and the like provided with a
plug fitting within such nozzle and having grooves through which the liquid to
be diffused in the form of spray is forced to-pass before it issues from the nozzle,
and also with an inlet bianch for.such liquid, in which a valve of conical or other
suitable form is arranged, such valve opening when the liquid is being drawn into
the syringe and closing when it is being expelled therefrom, substantially as
specified.
•
"
2. Fitting the inlet opening or branch of garden syringes and the like with
a cap or cover of perforated metal or wire gauze, substantially as and for the
purpose specified.
