Improvements in the Valve Apparatus of Explosion Motors.
We, EDOUARD ALEXIS VIVINUS and AUGUSTE JULES HECHT, both of Schaerbeck-
lez-Bruxells, Belgium, Engineers, 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 improved arrangement of valve apparatus for
explosion motors and has for object to enable the valves to be quickly and easily
put together and taken to pieces in order to permit of examination and if
necessary the immediate replacing thereof, a matter of considerable importance
in the case of the motors of autocars.
According to our invention two removable valve cases are so arranged that
they are independent of the body of the motor, the two cases being, by means of
screw bolts, simultaneously secured to a common support carried either by the
cylinders or by the cover of the motor.
The holding bolts are arranged so that they can be taken out sideways from
the valve cases, the heads of the bolts being hook-shaped and fitting on to
inwardly and upwardly inclined surfaces made in one of the valve cases.
The accompanying drawings show a construction of valve apparatus according
to our invention Fig. 1 being an elevation partly in section of the two valves
fitted to an explosion motor and Fig, 2 a vertical section of the same along the
line Fig. 1.
a is a piece or casing provided with the seat for the admission valve b, and c
is another piece or casing provided with the seat for the exhaust valve & which is
especially exposed to the hot exhaust gases. The valve casings a and c are
completely independent of the cylinder or of the motor cover; they are secured,
with or without the use of a joint, to a common cylindrical support e, which in
the example shown is cast in one with the motor cover f and the interior of
which communicates with the explosion or compression chamber of the motor.
The two valve casings a and c are simultaneously secured to their support e by
two screw bolts gg, the upper part of each of which passes between two side
lugs hh cast in one with the casing a of the admission valve, the nuts of the
bolts being screwed home against the upper surface of these lugs; whilst the
opposite ends or heads of the bolts. are hook-shaped (see Fig. 2) and press
against inwardly and upwardly inclined surfaces made on the exterior of the
exhaust valve casing c. The casing a is provided with connecting tubular
portion for the gas admission pipe whilst the casing c is provided with connecting
tubular portion for the burnt gas exhaust conduit. The igniter may be screwed
to the support e.
When it is desired to take the arrangement to pieces in order to examine
the valves it is only necessary to slightly loosen the nuts of the bolts and to
remove these bolts laterally from the casings a and c in order to immediately
render these parts free and ready to be lifted off, examined and put quickly
together again. When an accident to these organs renders it necessary to replace

page_text: them by fresh parts, these can be put in position in a few seconds, it being only
necessary to place the casings against the support e, to hook on the two bolts g
laterally beneath the inclined surfaces k of the lower casing by placing them
between the lugs of the upper casing and to then tighten the nuts; the two
casings are in this way tightened up simultaneously in situ and the motor is
once more ready to start.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. Valve arrangement for explosion motors in which the casings of the two
valves are removable or independent of the body of the motor and are arranged
so that they can be simultaneously screwed on to a common support carried
either by the cover or by the cylinder of the motor substantially as described.
2. In a valve arrangement such as that specified in Claim 1 the combination of
of removable valve casings, a support therefor and holding bolts so arranged
as to screw the two casings on to their support and to be capable of being removed
laterally from the said casings and supports substantially as described.
3. In a valve arrangement of the kind specified in Claim 1 the combination of
removable valve casings arranged opposite one another, a support for the cases,
and screw bolts whose heads are hook-shaped and adapted to engage inclined
surfaces on the exterior of one of the valve cases substantially as described.
4. Valve apparatus constructed and arranged as shown in and described with
reference to the accompanying drawing.
Dated this 20th day of Tune 1900.
