PROVISIONAL SPECIFICATION.
Improved Means for Destroying Weeds and other Obnoxious
Growths.
I MARK VICE, of Abbey Street, Bermondsey, S.E. Forage Merchant, do
hereby declare the nature of this invention to be as follows:-
This invention refers to improved means for destroying weeds and other obnoxious
growths, and consists of an implement for containing a suitable weed-exterminating
liquid, a predetermined quantity of which, by means of the implement, can be
injected into the roots of the said weeds or the like.
According to my invention, I provide a hollow tube of brass or other suitable
material fashioned at one end into the form of a spike.
At the other end of this hollow tube is a screw-top, which closes the hollow tube.
In this screw-top is formed an opening through which passes the end of a rod, which
travels nearly the entire length of the hollow tube.
The other extremity of this rod enters into an inner tube, around which is a coil-
spring, which presses against a circular projection on the aforesaid rod.
The upper part of the said circular projection, forms in its normal position, a
valve or stopper for closing the entrance to the chamber formed by the aforesaid
hollow tube or case. This hollow tube or case will be filled or partly filled with
any suitable liquid weed-destroyer, an inlet being provided in the hollow tube or
case, for the introduction of same."
When the beforementioned spike at the end of the hollow tube or case is inserted
into the roots of the weed or the like, the upper extremity of the beforedescribed
inner rod, which projects through the screw-top of the hollow tube or case as
aforesaid, so as to form a push-piece, is depressed, thereby opening the outlet in
the chamber formed by the hollow tube or case, and allowing the liquid to travel
down the inner tube, and so through perforations formed in the case, into the
punctured root of the weed or the like which is being operated upon.
In order to regulate the supply of liquid to each weed, a second chamber is
divided off by a horizontal partition or roof, which has a circular or other opening
in same, through which the liquid weed-destroyer passes, into the said chamber.
This chamber is normally kept filled with the liquid, but when the beforedescribed
valve, in the bottom of same, is opened, the chamber is gradually emptied of its
contents, and to prevent fresh liquid from entering same, a projecting rim formed
on the rod, is provided at a convenient distance above the eutrauce in the above-
described second chamber, so that when as aforesaid, the valve in the bottom of
the said chamber is opened by the action of the rod being depressed, the same
movement will bring the said projecting rim on the rod, over the entrance to the
second chamber, and so prevent more liquid from entering same.
Suitable means may be provided for preventing the perforations in the puncturing
end of the implement from being clogged by earth or the like.

Improved Means for Destroying Weeds and other Obnoxious
Growths.
I MARK VICE, of Abbey Street, Bermondsey, S.E. Forage Merchant, 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 improved means for destroying weeds and other obnoxious
growths, and has for its object an implement for piercing the roots or other parts
of weeds and other noxious plante, and injecting into the incisions so formed, a
suitable quantity of weed-exterminating liquid, in a.novel, simple, and effective
manner.
And in order that my invention may be the more readily understood, I have
shewn same upon the accompanying sheet of illustrative drawings, wherein :
Fig. 1 is a section of the implement,
Fig. 2 being a side view of the exterior of same.
Like letters of reference indicate corresponding parts throughout the drawings.
A is a tube or cylinder of brass or similar non-corroding metal, having "sweated,"
or soldered in one end, a brass or other plug a, provided with a screw-threaded
projection a' upon which is screwed a nozzle B tapering to a point, to form a
piercer b.
י.
This piercer is perforated longitudinally forming a minute passage b' leading to
the opening or slot 6 which is bevelled off towards the point of the piercer as
shewn in Fig. 2, so that the mould and dirt will not clog the passage, and also to
render it easy of clearing out such extraneous matter as is caused to lodge in the
said passage. The liquid poison with which the implement is charged, also finds
its way out through this opening or slot 6 as well as through the point of the nozzle.
The passage of larger diameter leading from the opening or slot & to a circular
chamber in which is fitted a coil or other suitable spring against one end of
which abuts the head of a presser-rod c, the other end of the spring pressing
against the shoulder 6*.
が
The rod c passes partly through a circular passage in the plug a, its end c¹ resting
against the end of the piston-rod C.
One end of the plug a is given a cup form, so that the end of the piston-rod C
may more readily be inserted in the passage formed in such plug.
The portion of the piston rod C, and the presser-rod c, have two of their sides
cut away, so that an end section of same would be triangular, and are so fashioned
for the purpose of allowing the liquid poison in the main chamber A¹ to escape
therefrom into the passage formed in the plug a, and so find its way through
the chamber and passage b', out through the slot or opening and the small
opening at the end of the piercer b, when the stopper or head c* is removed from
the end of the passage by the action of the piston-rod C being depressed or pushed
down.
The spring returning the stopper or head to its normal position when
the downward pressure upon the said piston rod is removed.
=
A top-piece Dis" sweated," or soldered in, or formed integral with, the end of
the tube or cylinder A, the said top-piece being perforated longitudinally at d
through which the rod C passes, through the suitably packed stuffing-box ', and
so through the screw-threaded milled-headed plug which closes same, the end c*
of the rod projecting a short distance through same, and being provided with a
head for convenience in pushing the rod C downward.
Handles E are provided for convenience in pressing the point of the implement
into the roots or other parts of the plants to be exterminated.
An inlet having a screw-cap is also provided for the purpose of filling the
tube or cylinder A with the weed-exterminating liquid.

page_text: The transverse pin G is intended to prevent the rod C sliding out when the
implement is held in an inverted position.
Having now particularly described and ascertained the nature of-my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is :-
==
.

tube or cylinder A, uozzle B, perforated piercer b, cupped plug a, top-pieco D,
and screw-plug substantially as described and illustrated in the accompanying
drawing.
2. In an improved implement for destroying weeds and the like, the combination
of the tube or cylinder A for containing the liquid, the nozzle B, having chamber b;
perforated piercer b with bevilled opening 6 cupped plug a top-piece D.; with
stuffing-box and screw-plug d³; the inlet F and handles E, with the rod C formed
as described at 2, having a transverse piu G, and the rod.c with stopper or head c³,
and also the spring 64, substantially as described and illustrated in the accompanying
drawing.
3. The complete implement for destroying weeds and similar plants, substantially
as described and illustrated in the accompanying drawing.
