Improvements in Instruments for Inoculating Vine-plants with
Di-sulphide of Carbon.
I, ALEXANDER SZIGETI, of Kecskemét, in the Kingdom of Hungary, Machine
Manufacturer, 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;-
The present invention relates to improvements in the instruments used for
inoculating vine-plants with di-sulphide of carbon. The improvements relate on
the one part to the container for the liquid and on the other to the valves.
The nature of the improvements is shown in the accompanying drawings, in
which Fig. 1 represents a longitudinal section of the whole instrument, with the
improvement, and Fig. 2 likewise a longitudinal section, on a larger scale, of a
valve with valve box.
The cylinder a of the container is made of some transparent substance such
as glass, so that the liquid contained in it is visible and there is a scale on the
cylinder a by means of which the quantity of fluid to be ejected may be regulated.
In cases where an opaque substance is used for the cylinder a instead of a trans-
parent one, some suitable appliance is adopted to indicate on the outside the
quantity of fluid.
A further improvement is in the position of the valves. Hitherto in these
instruments only one pressure valve was provided and this was in the line of the
longitudinal axis of the instrument. The drawback of this system was the
difficulty of cleaning and the fact that when a valve began to leak the instrument
became useless. To remove this drawback, I provide one or several valves and
place them at the side.
In the accompanying drawings the valve-box bis at the side of the channel c;
there may be several valves in the present case (Fig. 1) there are, for instance,
three. The valve box is closed by the lid d; by opening the lid the spiral valve e
can easily be taken out and cleaned.
The valve e consists of the disc f made of leather or such like material, fitting
into the hollow of the plug g, and pressed by the spring / against the valve
seat i.
The method of proceeding is as follows:
--
The fluid enters the channel c through the openings m m. From there it is
forced on to the valve or valves by pressing the knob k of the piston 7. The
piston has a leather jacket. The pressure upon the piston has to overcome the
resistance of the spiral spring p. If there are more than one valve they are con-
nected with each other by channels. When the fluid has passed through all the
valves it reaches the outlet o.
As soon as the pressure upon the knob k is discontinued the piston recedes to
its former position in consequence of the action of the spring p. A vacuum is
hereby created in the channel c, the suction of which serves to draw in more
fluid through the openings m m.
At the upper end of the piston rod of piston / are the rings r which also serve

page_text: to regulate the quantity of fluid to be ejected by limiting the stroke of the piston
rod.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is.
-
1. The improvement in instruments for inoculating vine-plants with di-sulphide
of carbon, consisting in making the cylinder a of the container of some trans-
parent material.
2. The improvement in the instrument described in Claim 1 consisting in pro-
viding the cylinder a with a scale by which the quantity of fluid to be ejected
may be controlled.
3. The improvement in instruments for inoculating vine-plants with di-sulphide
of carbon consisting in the instrument being fitted with an appliance which will
indicate on the outside the quantity of fluid contained in it.
4. The improvement in the instruments described in Claims 1 and 3 consisting
in providing rings 2 at the upper end of the piston rod by which means the
quantity of fluid to be ejected may be controlled.
5. The improvement in instruments for inoculating vine-plants with di-sulphide
of carbon, in which the valve or valves are placed at the side, in order to be more
easily accessible.
6. The improvement in the instruments described in Claims 1 to 4, consisting
in placing the valves as described in Claim 5.
7. The improvement in the instruments described in Claims 1 to 6 consisting
in providing several valves, connected with each other by channels so that if one
valve begins to leak the others will still hold back the fluid.
8. The improvement in instruments for inoculating vine-plants with di-sulphide
of carbon, such improvement consisting in a valve e in which a disc f made of
leather or such like material is fitted into a hollow in the plug thus securing better
and more durable packing.
9. The improvement in the instruments described in Claims 1 to 7 consisting
in providing them with one or more of the valves as described in Claim 8.
