COMPLETE SPECIFICATION.
Valves and Connections for use in Compressing, Exhausting, or
Storing Air or other.
I HERMANN KUDINE of Steglitz near Berlin in the German Empire, Engineer do
hereby declare the nature of this invention and in what manner the samé is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The present invention has for its object the removal of those drawbacks which arise
when vessels or receptacles of any kind or material are placed under pressure or
during evacuation of same, the vessels being of small size to which the application of
the means as used in the case of extensive operations, is unsuited. If, for instance,
generating gases are to be carried off, or articles of use having elastic walls to be
provided with compressed air, a good and speedy result is attained by using the
following process:
The article (Z) being dealt with, is at a suitable place provided with a short tube A.
This may be of ordinary form (see Fig. 2), or of particular construction such as
is shown in Figs. 6 to 14. In Fig. 2 closure of the tube A is effected by an ordinary
plug cock X
According as the introduction of compressed air or the exhaustion of air or gases
is to be effected, a valve-piece Y of peculiar construction is applied to the tube A,
said valve-piece carrying a specially constructed valve X.
The air-pump W can be brought into connection with the said valve-piece, or it
may be permanently united with same.
The main feature of the invention is that the vessel is provided only with the tube,
and not with tube and valve, so that it is always ready for use and is independent
from defects in the latter.
Taking for example the india-rubber tyre of a cycle, by removal of the valve from
same, i.e. when the tyre is provided only with the tube, it can never occur that the
tyre fails in action by the valve becoming injured when riding. Similarly in
the case of the absorption of corrosive gases or fluids, where the valve, if it is on the
tube is very soon corroded by the gases and fluids, examination or control in the case
of such an arrangement being very difficult.
On the accompanying drawing the fundamental principles of the invention are
shown:

Fig. 2 shows the parts in part section and disconnected.

W the air-pump.
The tube A is either of ordinary form (Fig. 2) or of special construction (Figs. 6-14).
A is the tube (Figs 6-8) a and b two central passages which at suitable distance
from each other have lateral branches ab, so that each passage in itself forms an
angle, curve or the like, or runs slantingly. The tube is covered by a cap B having a
groove C. parallel or nearly parallel with the passages a and b which effect a connection
between the passages a a¹, b b¹, on the cap B being suitably turned, so that there
is only one channel in bent or other form, which admits of being used as inlet or
outlet, accordingly, upon the tube being brought into connection with the necessary
medium: A lock-nut D), nose-piece or the like forms a means for securing the cover,
on the tube, closing being effected by a thumb-piece E or the like.
In the three modifications shown in Figs. 9 to 14, the tube A has a central
passage a; a¹ is the lateral branch, B the cover, C the communicatory passage or
groove, E the thumb-piece serving as closing means, D the lock-nut for the cover,
H stop-pin, I guide for same on cover, K connection for suction or compression
medium.
The cover B, of any desired form, has a groove or grooves which may be brought
into connection with the passage in the tube, thus establishing a connection making
the tube applicable as inlet or outlet. This is done by turning the cover, whereby the
lock-nut, nose etc. serve as locking means and at the same time as stop to limit its
motion. The cover has a further arrangement which renders it applicable for connec-
tion with a compressing or suction medium, such as an air-pump; such means may be
a screw junction-piece K.
The valve X consists essentially of an elastic material which acts automatically by
tension in the vessel, or the pressure thereby exercised, or by an elastic ring N,
spring O or other suitable arrangement forming a closure and acting as relief valve.
As shown on the drawing, this valve has the form of a funnel, of any desired material,
india-rubber being preferable. The funnel tube L ends as above described in a
capillary M (Fig. 2); Fig. 3 shows the substitution by springs O; Fig. 5 by ring N ;
Fig. 4 shows a valve with outlet P and three way cock R, suitable for use in exhausting
gases and the like.
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:
1. A process and mechanism for placing under pressure, or for the evacuation of'
vessels or receptacles (Z) of any kind, as also of other similar articles, the same con-
sisting in the article (Z) being provided with a closable tube (A) of particular
construction, which tube when in use is connected with a valve-piece (Y) likewise of
particular construction, said valve-piece being further in connection with an air-
pump (W), the valve-piece and pump being also capable of permanent connection, all
substantially as and for the purposes hereinbefore set forth.
2. In a process as claimed in claim 1, a closable tube (A.) of such construction that
the central passage (a b) is interrupted at the middle and deviated to form
branches (a' ') the tube (A) being encircled by a cover (B) suitably locked, and
having in its interior a communicatory groove (C) which when the cover is
appropriately turned, makes or prevents communication between the two branches (a¹ b¹)
all substantially as hereinbefore set forth.
3. In a process as claimed in claim 1, a closable tube (A) with lateral passage (a a¹)
in combination with a suitably locked cover (B) having communicatory groove (C),
stop (HF) and screw junction piece (K) for connection of the compression or suction
medium, for the purpose of effecting or preventing flow, all substantially as
herein before set forth. .

page_text: 4. In a process as claimed in claim 1 a valve-piece (Y) with internal flexible
tube (L) which in a state of rest, by the pressure of the tension produced in the
vessel (Z) is held together automatically or mechanically by a compressing medium
such as a capillary (M), springs (0) Ring (N) or the like, all substantially as
hereinbefore set forth.
Tated this 8th day of September 1897.
