Year: 1884

page_text: COMPLETE SPECIFICATION.
I EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35 Southampton Buildings Chancery Lane in the County of
Middlesex do hereby declare the nature of the Invention for "IMPROVEMENTS
IN APPARATUS FOR TREATING VINES OR OTHER PLANTS WITH INSECTICIDE
LIQUID OR OTHER SUBSTANCE" 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 more especially to the Invention for which I obtained
Her Majesty's Royal Letters Patent dated March 15th A.D. 1883, and numbered
1382, for "An Improved Apparatus for Injecting Insecticide Liquid or other
Substance into Vines or other Plants."

The present Invention has for its object improvements in the general
arrangement and in the details of apparatus constructed according to the said
Invention.
In the accompanying Drawing which is in illustration of this Invention,
Figure 1 represents an injecting apparatus or nozzle with a straight metal cone.
Figure 2 a similar nozzle having an elbowed metal cone.
Figure 3 shows a different form of metal conė.
Figure 4 is a non-metallic nozzle without a cone.
ر
Figure 5 represents the ordinary coned nozzle having its point bevilled.
Figure 6 shews the coned nozzle screwed at its extremity in order to fix it either
directly into the plant to be treated, or into a suitable metal plate applied to the
plant or tree. In the latter case the plate would be provided with a boss into
which the point would be screwed so as to hermetically close the opening in the
metal and in the branch or tree operated upon.
Figure 7 shews a metallic plate fitted with a soft lining of gutta percha, leather,
india rubber, cork, cloth, or other suitable material, a being the hole, and 6 bands
or strings by which the plate can be fixed upon the tree.
Figure 8 shows an injector, the stem of which passes through a metal or other
plate or band.
Figure 9 shows an injector of india rubber or other suitable soft material fixed
directly upon the tree by strings
Figure 10 shows a hole in the tree withinotches in the hark.”

page_text: Figure 15 shews a novel arrangement of apparatus for filling the elastic balls
described in the former Specification already referred to. f is a pipe conveying the
liquid forced into the reservoir g. h is a cock upon the reservoir g. k is a glass
guage tube shewing the height of the liquid in the reservoir g. 1, 1, are pipes
through which the liquid under pressure passes into the distributing vessels i, i,
and thence to the several regulating cocks m. The guide rails n, n, support the
injectors whilst they are being filled by the flexible pipes p.
In cases where the liquid used is of such a nature as would destroy the elastic
balls used as injectors, they may be replaced by screws.
For this purpose a hole of greater depth than the length of the screw is made in
the plant, as shewn in Figure 11, this hole being filled with the liquid and the
screw screwed in so as to compress the liquid forcibly and prevent its escape by the
sap, and all contact with the external air.
By this means, any desired chemical reaction may be produced in the stem of
the plant.
Figure 12 shews different forms of screws to be used in the manner just
described.
Or instead of screws, a metallic injector may be used. Figure 18 shews a
hermetically closed conical metal vessel terminating in a pipe screwed at its
extremity, and provided with a cock.
When this vessel is fitted upon one of the filling pipes of the filling apparatus, the
cock being open, it will be filled with gas or liquid under a pressure dependent upon
the force applied to the pump. If a small quantity of liquid be introduced, and
then air under pressure, and the cock is then closed, the liquid and gas will not
escape when the vessel is removed from the filling pipe. The screwed end of the
pipe upon the vessel being then screwed into the stem of the plant and the cock
being opened, the injection of the gas or liquid will proceed automatically, the
liquid first entering the plant and then the gas according to the position of the
instrument and the pressure of gas employed.
This instrument is useful more especially for substances affecting india-rubber
and which are intended to effect chemical decomposition; if for instance it is desired
to inject into the plant a current of hydro-sulphurous acid gas together with
sulphuret of iron mixed with hydrochloric acid.
And in cases where metal would be attacked by the substances employed, a
glass vessel may be used as shewn in Figure 14, in which the chemical
decompositions are effected and whence the gases disengaged pass through a short
piece of india rubber tube fitted to the end of one of the simple injectors fixed in
the tree.
With the novel apparatus described and shewn all known diseases or affections
of the vine, such as pyralis, phylloxera, or phylloxera eggs, mildew, or oīdium, or
diseases or affections of other plants, can be treated.
I do not claim the precise form and proportions of the several parts of the
apparatus described and shewn, which may be varied to suit varying circumstances,
but 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: The apparatus for injecting liquids, or gases into vines or other plants,
substantially as and for the purposes described and shewn in the Drawing.
