Complete Specification Left, 23rd Dec., 1896-Accepted, 20th Feb.. 1897
I WILLY SECK of Oberursel near Frankfort-on-Main in the Empire of
Germany, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to an outlet-valve motion for gas- and oil-engines with
several cylinders.
As shown by the accompanied drawing there is fixed on the crank-shaft A the
worm B which drives the screw Con the shaft T. The shaft T moves the
eccentric D and the crank-pin E. By the connecting rod F the crank-pin moves
the lever G, which is connected by the bolt H with the motion-bar K, moving
the latter forwards and backwards; the eye L serves the bar as a guide.
The motion bar bears the lifters i, the one of which is fixed to the bar,
therefore moving equally with the bar, whilst the other is moved by the
eccentric D, the bent-lever M and the connecting-rod N, therefore sliding on the
motion bar.
The engine works upon the "Otto "-cycle, consequently the outlet-valves must
open on every second inward stroke of the pistons.
The gearing of the worm and worm-wheel is 1:4, consequently the lifters slide
during four revolutions of the crank-shaft once forwards and once backwards and
lift the rolls O O' which are connected to the spindles P P of the outlet-valves.
The outlet-valves are opened therefore once whilst the crank-shaft makes two
revolutions.
The motion of the lifter which slides on the bar K, may by other means be
effected for instance by fixing it to a second motion bar which is connected to the
bent-lever in the same manner as the har K is connected with the lever G.
Q is the body of the engine, R R are the two cylinders, S is one of the shaft-
bearings.
Altering the gearing of the worm and worm-wheel to 1:2, this mechanism may
as well be applied to two-cycle engines.
Deted this 14th day of April 1896.

I, WILLY SECK of Oberursel near Frankfort-on-Main 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 relates to an outlet valve motion for gas and oil engines with
several cylinders.

page_text: As shown by the drawing accompanying the Provisional Specification there is
fixed on the crank shaft A a worm B which drives the worm wheel C on the
shaft T. The shaft T moves the eccentric D and the crank-pin E. By the con-
necting rod F the crank pin moves the lever G, which is connected by the bolt H
with the motion bar K, moving the latter forwards and backwards; the eye L
serves the bar as a guide. The motion bar bears the lifters i i¹, one of which i is
fixed to the bar, therefore moving equally with the bar, whilst the other ¹ is
moved by the eccentric D, the bent lever M and the connecting rod N, therefore
sliding on the motion bar. The engine works upon the "Otto "-cycle, conse-
quently the outlet valves must open on every second inward stroke of the
pistons.
The gearing of the worm and worm-wheels is 1 : 4, consequently the lifters slide
during four revolutions of the crank shaft once forwards and once backwards and lift
the rollers O O which are connected to the spindies P P¹ of the outlet-valves. The
outlet-valves are opened therefore once whilst the crank-shaft makes two revolu-
tions. The motion of the lifter ', which slides on the bar K, may be effected by
other means, for instance by fixing it to a second motion bar which is connected to
the bent lever in the same manner as the bar K is connected with the lever G.
Q is the body of the engine, R R are the two cylinders, S is one of the shaft-
bearings.
If the gearing of the worm and worm-wheel be altered to 1:2, this mechanism
may equally well be applied to two-cycle engines.
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. An outlet valve motion for gas and oil engines characterised by the outlet
valve being raised both on the outward and inward stroke, by means of lifters
arranged on a bar receiving a backwards and forwards motion from a shaft
driven by gearing in the proportion of 1:4 substantially as hereinbefore set
forth.
2. The general construction and combination of parts taken as a whole, forming
the improved outlet valve motion for gas and oil engines, substantially as
described and illustrated.
