I, PAUL REIMANN, of Landsberg on the Warthe, in the Empire of Germany,
Engineer, 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:
This invention consists in the arrangement of a fixed abutment for the swinging
lever of a regulating valve, which oscillates on a movable fulcrum. The object
of the new arrangement is, that, when the valve which is usually depressed by a
spring, or weight is owing to any circumstances whatever, brought to a standstill,
the closing of the valve is effected by the valve lever striking against the abutment,
and thus forcing the valve cone to descend.
In the accompanying diagrams which illustrate the invention, Figures 1 and 2
show the auxiliary closing apparatus when the valve is at the lowest and highest
points respectively. Figures 3 to 5 show a practical form of the lever represented
in Figures 1 and 2 in three different working positions. Figure 6 shows the
arrangement of this apparatus in connection with, for example, a Widemann
regulating valve.
The invention referred to applies to that class of valves whose valve levers aro
secured to the valve spindle, and where, therefore, the valve levers have a movable
fulcrum, as for example, in Widemann's Proell's, Hartung's and like valve gear.
The principle of the invention is, that, when the valve remains suspended to
the valve lever on account of its altered position, its fulcrum describes another
arc, and consequently strikes against an abutment which it does not touch in its
normal orbit.
As may be seen from the diagrams, Figs. 1 and 2, the valve arm a is brought
alternately into the positions cd, and gh, through the action of the closing
spring on the one hand, and the rolling plane b of the lever arm a on the other
hand. The lines e-d and g- intersect geometrically speaking at the point e,
(Figure 2).
Inside the triangle d, e, g, formed by the two positions mentioned an abutment i
is placed, which effects the forced closing of the valve. If the power of the spring f
fails, after the lever swings after it is taken off the position g, h, round the new
fixed point h, g.
In this way it strikes the fixed abutment i and is by this again
forced to take up the position c, d, and close the valve.
In practice, the diagrammatic form of the lever arm shown in Figs. 1 and 2 is
modified as is shown by Figs. 3 to 5, wherein a form of adaptation is shown. Here
the arm is provided with a special nose n for contact with the abutment, and
through this construction the dead movement of the arm between the two abut-
ments i and b is lessened; and, therefore, the closing movement is hastened when
the valve sticks.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
Auxiliary closing apparatus for regulating valves which are opened with the
help of a lever arm rolling against an abutment, and closed by a spring or weight
characterized by the arrangement on the opposite side of the broad abutment 6 of
the lever a of a second fixed abutment i against which the arm a strikes-when the
valve cannot be depressed by the force of the spring etc., while moving in the
valve closing direction, and consequently this arm by utilizing this abutment as
a point of support depresses the valve forcibly into its place.
