7b all whom it may concern:
Be it known that I, HAMILTON G. BLUM-
BERG, a citizen of the United States, residing
at San Antonio,.in the county of Bexar
5 and State of Texas, have invented certain
new and useful Improvements in Cylinder-
Heads, of which the following is a speci-
cation.
This invention relates to an improvement
10 in removable cylinder heads for gas engines
which can be applied to any number of cyl-
inders, and the object is to provide integral
intake and exhaust conduits. Water is re-
ceived within the head for maintaining it
15 in a cool condition, and the water is caused
to circulate around the intake and exhaust
conduits and around the valve guides, so
that all of the parts are maintained in a cool
condition.
20 The invention relates to still other novel
features of construction and combinations of
parts which will be hereinafter more fully
described and pointed out in the claims.
In the accompanying drawings:
25 Figure 1 is a longitudinal vertical sec-
tional view; -
Fig. 2 is a transverse vertical sectional
view ; and
Fig. 3 is a horizontal sectional view.
so A represents the head, which is prefer-
ably made hollow for forming a -Rater cham-
ber through which the water may circulate
for maintaining the head in a cool condi-
tion. I have only shown the head as being
35 applied to two -cylinders, but it is not the
intention to limit the application of the head
to any - particular number of cylinders.
For each engine cylinder, as is well known,
there is an exhaust and intake port, and in
40 this instance I have shown two exhausts and
two intakes. The exhaust and intake con-
duits are cast integrally with the head, and
the exhaust conduits are designated as 1, and
the intake conduits as 2. ' The exhaust con-
45 duits are provided with a port which leads
from one side of the casing through the
lower side thereof, as at 3, to the engine cyl-
inder, through which the exhaust gases from
the engine cylinder are discharged. The in-
5o take conduits 4, 4 are located adjacent to
each other, and are so constructed thajt at
their outer end they converge into a single
conduit as at 5, each conduit 4 leading to an
engine cylinder, while the conduit 5 leads to
65 the manifold, not shown. By this construe-.
Lion, a bettor distribution of th.e ';q" is o -tained, than by the usual four-way method,
generally provided.
The intake and exhaust ports, and par-
ticularly the exhaust ports 3, are formed co
along the upper wall of the conduits 1 in an
are of say forty-five degrees. The purpose
of this is to prevent the exhaust gases from
carrying any gases, lubricating oil, carbon,
or soot into the valve guides 6, which are 65
connected to the conduits and head, and ex-
tend above the head A for forming a guide
for the valve stems 7, which carry the
valves 8.
With the conduit or port generally pro- 70
'ided in gas engines, the exhaust gases will
enter the guide along the valve stem, and
eventually cause the stems to stick, but with
the formation of the wall of the port at an
angle of forty-five degrees at the point where 75
the valve stem slides into the guide, it is pos-
sible to overcome this objection, and prevent
the direct influx of the gases into the valve
guides. The intake ports are provided with
Svalve 9, which have stems 10 connected SO
thereto, sliding through guides 11, which are
constructed similarly to the guide conduits
and stem 7 of the exhaust stem 7.of the ex-
haust valves. These valves are seated against
the lower side of the head for forming a 85
closure for the exhaust and intake ports, and
are held .in this position by means of the
springs 12, 12.
The water jacket 13 around the engine
cylinders B is in communication with the 90
chamber of the head A, so that a constant
circulation of water is maintained. The in-
let of the water is provided as at 14, in the
water jacket of the cylinder, and the out-
let port as at 15, of the head A. The head, 95
of course, is connected to the engine cylin-
der by means of bolts, 16.
I claim:
1. The combination with a cylinder head,
of intake and exhaust conduits integrallyI 10
cast therein, valves for closing the conduits,
valve stems connected to the valves eter :
ing through the head, said conduits haviit
the upper walls thereof, where the val
stems pass through the head, formed in the 05
arc of a circle for causing the exhs'4 gases
and foreign matter carried therewith to pass
through the conduits without affecting the
valve stems, the arched portion of said con-
duits extending beyond the point of en- }_L
trance oai: Ivlve.
