This invention relates to new and useful im
provements in valves.
_
One object‘of the invention is to provide an
improved valve ‘structure which may be readily
5 install'edin the intake chamber of a gas engine
'to control' the admittance of fuel to said engine.
An important object of the' invention is to pro
vide an improved valve structure including a
valve head which is arranged to be mounted in
10 the intake chamber of a gas engine in place of
the usual large single valve; said head having a
plurality of relatively light valves mounted there
in, whereby battering or marring of the valve
seat due to the pounding action rof a large valve,
15 which is relatively heavy, against said seat is
eliminated.
'
j‘ectito vari-ation; as it has been found that the
same is readily mounted in any of a number of
>standard-gasengines, namely, “Bessemer”, “Su
perior”, “Marion”, “J.> C.”, and “Reid”. The
A‘valve chamber is provided with a transverse par
tition YIl* ‘located at sumtantially mid-height
therein and `an.- opening I2 in the top» of the
‘chamberijestablishes communication between the
interior _of the' chamber and the'corn'bustion
chamber of'> the engine (not shown). A horizon lil
'tal inletport YI3rextends through the wall of the
casing below thej partition II~ to admit theV fuel
mixture into the chamber> lil, while a central cy
lindrical; opening I4 isv formed in the partition, >
whereby the fuel Vmixture may flow upwardly :i
through said opening I Il> and chamber, from
Another object of the invention is to provide
an improved valve cluster which is adapted to be
substituted for the usual single intake valve of
'where it is conducted to thev engine. ‘_Manifestly,

light Valves control the admission of fuel, said
valves being actuated by the engine suction and
due to their light weight are quick opening and
closing, whereby fuel waste is minimized; each
25 valve being individually mounted in the assembly
to permit its repair or replacement without af
fecting the other valves.
’
A further object of the invention is to provide
an improved valve cluster of the character de
scribed, wherein the stroke of the individual
valves is limited which eliminates hammering or
pounding of said valves in operation; said valves
being arranged >to seat on a head forming part
of the assembly, whereby operation of the valves
35 causes no appreciable wear on the engine valve
chamber.
A construction designed to carry out the in
vention will be hereinafter described, together
with other features of the invention.
The invention will be more readily understood
40
fro-m a reading of the following specification and
by reference to the accompanying drawing, in
which an example of the invention is shown, and
wherein:

VThe upper vportion of 'the' opening I? is en
larged' torform an annular seat I5’and it has
been the usual practice to employ a single valve
Yadapted to engage the seat. Such a valve is
guided' in’its movement by a depending stem
Whichis' s'lidable in a sleeve or collar I6 extend
¿ing upwardly from the bottom of the chamber
Ill.Y The'single Valve is comparatively heavy in
weight and' since engine suction is depended upon
to raise said valve, the’ operation of the same is 30
relatively slow. Also, the'weight of the valve
causes'the same to seat with a great deal of
force'which batters the seat I5, resulting in a
poor seating engagementwiththe valve. Vlïhen
said seat vdoes become worn, it is necessary to
eitherV replace the entire> intake chamber or re
move the same from the lengine to repair it. Fur
ther, wear of the valve itself requires replacement
of the entire valve.
'
. '
To overcome theY disadvantages of a single valve
such as is now in common use, a cylindrical
valve head I1, is inserted within the opening I4
and is supported on the annular shoulder I5, as
is clearly shown in Figure 1. An axial shank i8
depends from the head, being preferably made 45
integral therewith, and said shank extends below
the bottom >of' the partition II .into the lower
end of the chamber l0. An axial stem I9 has its
upper end threaded in the bottom of the shank,
while its lowerV end is inserted within the »up
wardly extending sleeve or collar I6. The bore
of the sleeve is threaded to receive the lower
threaded end of the stem and manifestly, the
stem acts toisecurely fasten theV head Il' on the
seat
I5.

be of any usual construction, such as may be

an >equal distance apart around the head. As is
purchased on the open market. The particular

Further, the valve disks and seats are not subject
10 vided. Each valve member is arranged to closef to severe pounding or hammering action because 10
one of the ports and since all of the members and ofthe lightness in weight of the valves and also
ports are exactly alike, a description of one mem
because of the limited movement which the valves
ber and its engagement, with its respective port undergo. If any one of the valve members be
will sufûce. Each valve member includes a valve
15 disk 22 having an annular bevel 23 on its under
side at its marginal portion. The upper end of
each port is formed with a complementary bevel
to form a seat 24 arranged to be engaged by the
bevel of the valve disk. A valve stem 25, prefer
20 ably integral with the disk, depends axially from
the underside of said disk and passes through a
vertical bore or opening 26 formed in a radially
extending guide boss or collar 21. The guide
collar is preferably made integral with the lower
25 end of the shank I8 and as clearly shown in Fig
ure 4, a guide collar is provided for each valve
member and is so positioned that the stem 25 of
said member passes through the bore thereof. A
suitable .guide sleeve 28 is inserted in the bore 26
30 of each boss or collar and surrounds the stem.
The sleeve has an annular flange 29 at its lower .
end which flange abuts the underside of the boss
when in position within the bore.
l
The lower end of each stem -25 extends below
35 its boss or collar and is enlarged as shown at 30,
whereby a flanged ring 3I may be slidably con
fined on the stem.
A coiled spring 3 I ’ surrounds
each stem, being confined between the ring 3|
and the underside of the boss or collar, and con
40 stantly exerts its pressure to urge the valve mem
ber downwardly with the disk 22 engaging the
seat 24. Thus, said springs tend to hold the valve
members in a closedposition, whereby communi
cation between the lower end and the upper end of
the
chamber is prevented.
45
Manifestly, the valve members 2I control the
now of the fuel mixture to the combustion cham
ber of the gas engine (not shown) and the size of
the ports 2li is such that their combined area ad
mits sufñcient fuel when the disks 22 of the mem
50
bers are unseated. The suction of the engine acts
upon the upper surface of the disks to unseat the
same under tension vof the coiled springs 3|' and
since the valve members are relatively light, said
suction quickly opens the members. Similarly,
55
when the suction is relieved, the springs 3I’
immediately seat the disks to close the openings.
The lightness of the members obviates the pound
ing or hammering action against their seats which
60 prolongs the life of both the seats and disks.
To limit the upward movement of the valve
members 2I so that the suction does not raise said
members farther than is necessary, a spider 32 is
formed with a central depending collar 33, which
collar rests on the top of the head I1 at the central
65 portion thereof. The spider arms 34 overhang the
disks 22 of the valve members 2I and a stud bolt
35 passes through a vertical axial bore 36 formed
in the spider and collar and is threaded into the
70 head I'I. Obviously, upward movement of the
members is limited by the disks 22 striking the
spider arms 34. . It is noted that other means for
limiting the >upward movement of the members
may be employed, such as providing a projection
75 on the stem LÈS-arranged to strike the underside of
come worn, it can easily be replaced Without
aifecting the other valve members. Also, if the 15
seats become worn the assembly may be removed
and said seat re-ground, or an entire new assem
bly substituted therefor. It is particularly noted
that the construction herein shown causes no wear
on the intake chamber as the shoulder I 5 therein
merely supports the head and does not act as a
zo
valve seat, as has been the practice heretofore.
