PROVISIONAL SPECIFICATION.
Improvements in Valves and Cooks.
I, ALOIS KOLBEN, of I Fleischmarkt 1, Vienna, in the Empire of Austria,
Master Tinsmith, do hereby declare the nature of this invention to be as
follows,
The closing of valves and cocks has hitherto been accomplished mostly by
pressing a flat or arched loaded or unloaded valve disc against a valve seat.
This method of closing has the disadvantage that owing to the same parts of
the valve disc being continually forced against the valve seat, a looseness in
the closing of the valve very soon takes place, especially with high pressure,
such as foi example with water conducting cocks
The object of the present invention is to do away with these evils, and to this
end the invention consists, as represented in Figure 1 of the drawing in longi-
tudinal section, in a valve-ball à being fixed loosely, that is to say so as to be
able to rotate in all duections, in a movable casing attached to the valve
spindle 0
By this arrangement of the movable valve-ball a perfect seating of the same
on the valve seat d is always maintained, thus sparing the latter to the utmost,
as owing to the friction caused by the water passing through the valve which
causes the ball to turn and its position to change, a different surface of the ball
is continually presented to the seating, so that a perfectly even wearing away
with a continual perfect tightness of the valve closing 18 brought about."
In Figure 2 a second form of carrying out the invention is shown.
The valve ball a in this form of construction remains free, thus lying upon
valve seat d without a casing. The pressing of the ball upon the valve seat
is in this form effected by a piston 6 which 18 movably fastened on the spindle c,
whereby it may be screwed down on to the ball On the raising of this piston
the valve ball is set free and the water lifts it automatically off the valve seat.

I, ALOIS KOLBEN, of 1, Fleischmarkt 1, Vienna, in the Empire of Austria,
Master Tinsmith, 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
1
The closing of valves and cocks has hitherto been accomplished mostly by
pressing a flat or arched loaded or unloaded valve disc against a valve seat.

page_text: This method of closing has the disadvantage that owing to the same parts of
the valve disc bong continually forced against the valve seat, a looseness in
the closing of the valve very soon takes place, especially with high pressure,
such as for example with water conducting cocks
The object of the present invention is to do away with these evils, and to this
end the invention consists, as represented in longitudinal section, in Figure 1
of the drawings filed with the Provisional Specification in a valve ball a being
fixed loosely, that is to say so as to be able to iotate in all directions, in a movable
casing attached to the valve spindle c.
By this arrangement of the movable valve-ball a perfect seating of the same
on the valve seat d 18 always maintained, thus sparing the latter to the utmost,
as owing to the fiction caused by the water passing through the valve which
causes the ball to tuin and its position to change, a different surface of the ball
18 continually presented to the seating, so that a perfectly even wearing away
with a continual perfect tightness of the valve closing is brought about.
In Figure 2 a second form of canying out the invention is shown
The valve ball a in this form of construction remains free, thus lying upon
valve seat d without a casing The pressing of the ball upon the valve seat
is in this form effected by a piston b which is movably fastened on the spindle c,
whereby it may be screwed down on to the ball On the raising of this piston
the valve ball is set free and the water lifts it automatically off the valve seat.
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 18:-
1. A ball joint for valves and cocks of all kinds consisting of a valve ball (a)
arianged loosely movable or revoluble in a casing (b) attached to the valve
spindle (c) in such a way that by the rotation of the ball caused by the water
passing through the valve a different portion of the ball surface is continually
presented to the seating, substantially as described
2. A form of construction of the ball joint, hereinbefore described in which
the valve ball rests loosely on the valve seat (d) and when the valve is closed is
pressed on the valve seat by means of a piston (b) movably mounted on 8
spindle (c), substantially as described.
