I LOUIS STROH of 44 Liebigstrasse, Frankfurt am Main, Germany, Manu-
facturer do hereby declare the nature of this invention to be as follows:-
The present invention relates to an outlet-valve-motion for gas- and petroleum-
engines.
An eccentric which is wedged on the crank-shaft of the engine with a convenient
leading-angle, is at its circumference provided with a number of worms which
catch into a worm-wheel which has a double number of teeth, and revolve the
same. This worm-wheel is situated in an eccentric-ring which is jointed to the
frame by an arm, and stands through a spindle in connection with a curve-disc
against which a slide, which is also situated on the eccentric-ring and carrying a
pivot, is constantly pressed by means of a spring.
In consequence of the double transmission between the eccentric and the worm-
wheel, the slide pushed once forward and backward while the crank-shaft is
making two revolutions, the curve-disc being placed in such a position that in the
high position of the eccentric the slide is in one of its extreme positions and stands
still for some time, while the motion of the valve takes place only when the
eccentric passes through the lower half of the circular course. Accordingly the
pivot will push against the valve-rod only at every second revolution of the crank-
shaft and raise the outlet-valve.
Dated this 30th day of November 1893.

I, LOUIS STROH of 44 Liebigstrasse, Frankfort of Main, Germany, 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 an outlet-valve-motion for gas- and petroleum-
engines.
Fig. 1 of the accompanying drawing shows the section of one part of the
contrivance in question,
Fig. 2 is the plan of the same, and
Fig. 3 represents the horizontal section through its toothing.
The eccentric a which is wedged on the crank-shaft of the engine with a con-
venient leading-angle, is at its circumference provided with a number of (in this
case 6) worms which catch into a worm-wheel b which has a double number of
teeth, and revolve the same. This worm-wheel is situated in an eccentric-ring c
which is jointed to the frame by an arm, and stands through the spindle din
connection with a curve-disc e against which the slide g, which is also situated on
the eccentric-ring c and carrying the pivot i, is constantly pressed by means of the
spring h.
In consequence of the double transmission between the eccentric and the worm-
wheel, the slide 9 is pushed once forward and backward while the crank-shaft in

high position of the eccentric the slide is in one of its extreme positions and stands
still for some time, while the motion of the valve takes place only when the
eccentric passes through the lower half of the circular course. Accordingly the
pivot will push against the valve-rod only at every second revolution of
the crank-shaft and raise the outlet-valve.
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 :
In an outlet-valve-motion for gas- and petroleum-engines the eccentric a which is
provided with a number of worms by means of which latter the eccentric catches
into the worm-wheel arranged in the eccentric-ring c, with a double number of
teeth, in order to-by means of the curve-disc e on the spindle d-move the slide y
in such a way that its pivot i pushes against the rod f of the outlet-valve only at
every second revolution of the crank-shaft, substantially as described.
