13 Claims. (Cl. 137-153)
Our invention relates to valves and more pap
ticularly to rotor valves for control of gas or
other fluids.
The general object of our invention is to pro
vide a single rotor valve adapted to service one
or more burners, in which is incorporatedy an
automatic- control to prevent intermediate vposi
tioning of the valve between certain adjustments.
Another object ofv our invention‘is to provide
a. rotor valve in combination with a pressure reg
ulator which is eiilcient under all conditions of
temperature and pressure.
Another object _is to provide a -rotor valve
adapted to automatically assure certain prese
lected adjustments, operating in combination with
a pressure regulator coacting with said valve.
Another object is-to provide a power control
for a rotor valve which will allow adjustment at
deñnite selected positions and prevent any inter
mediate adjustment between those positions by
returning the valve automatically to the selected
la L!
Another object is to provide a rotor valve which
supplies gas selectively to a low burner adjust
ment and to a high burner adjustment, which is
equipped with a power means acting circumfer
entiallyto prevent any intermediate adjustment
between low and high burner adjustment and
which will allow all stages of adjustment between
low burner and off position.
A further object is to apply a tangential force
to thegsliding element of a rotor valve which will
tend to rotate the rotor when opposed by a cam
face and allow the rotating element to retain its
position when bearing tangentially against the
side of the cam.
A still further object is to apply a spring con
trolled element tangentially to the rotating mem
ber of a rotor valve whose action will be initiated
40 by contact with a cam -face on assumption by the
rotor of a ñrst preselected adjustment and con
tinue to return the rotor to that adjustment until
the cam point has rotated past the element to as
sume a second preselected adjustment and which
will again continue to return the rotor to the
i'lrst adjustment when the cam point has passed
the element on- reversal of the rotating motion.
Another object is to provide a rotor valve com
bined with a steam pressure shut-off in which the
50 rotor and shut-oil’ means are housed within the
valve and in which the automatic features are
concealed and simpliiied.
In pursuance of the foregoing'objects We aim
to provide' a rotor valve housing a steam pressure
regulator and a rotor member, which supplies se
lectively a small burner alone and jointly a small
burner and a large burner with a regulated gas
supply and which can be set in all intermediate
stages of adjustment between shut-oil.’ position
and “on" position for the small burner but which
cannot be set for any intermediate stages between
the full “on” position for both burners and an
adjustment at which the large burner is shut off,
which corresponds simultaneously with a full
“on” position for the small burner alone. Fur 10
ther objects and advantages of our invention will
become apparent as the description proceeds
taken- in connection with the accompanying
-drawings which form a part of this specification.

While our invention is susceptible of embodi

the drawings and will herein describe in detail a
preferred embodiment thereof, together with sev
eral modifications, with the understanding that 35
we do not intend to limit our invention to the par
ticular construction and arrangement shown, it
being contemplated that various changes may
4be made by those skilled in the art without> de
parting from the spirit and scope of the appended 40
A need has been felt for a combined valve' and
regulator for :iiuid ñred steam devices which will
maintain its high eiiiciency under all conditions
of temperature and pressure. In adapting a. ro 45
tor valve to this function problems were pre
sented in connection with regulation and control
where one valve jointly serves several outlets.
Steam pressure regulators operating on a diaphragm have beenï known, but it is felt that pre 50
viously no attempt has been made to combine the
beneñts of a rotor valve with a steam pressure
regulator in a novel, well protected manner. The
principle of the rotor valve has been Acalled upon
to perform this service and the application .is
. devoted in part to the solution ofthe attendant

would customarily occupy on the side of a gas
heated steam radiator of the type usually used for
space heating purposes.
base portionv 5 screws
into the radiator by means of threads 6 and to
it is attached the body 1 of the valve~ by means of
screws 8. Within the body-and rotatably sliding
10 thereon is a rotor 9 which is turned by handle I8
by means of stem I I to which both are firmly at
this end the handle III is provided with a pointer -
35, which, aided by marks on the body, indicates
Gasfenters the valve at -inlet I5, shown also
the corresponding position of the rotor.. Slots ` ‘I
or stops 36, 31 and 38 are formed in a head piece
48 and are adapted to receive a wedge portion
39 of the handle to retain the handle immovable
in the respective positions of' “off”, “low” and
“high”._ A coiled spring 4I acts between the bot
tom of 48 and a washer 42 bearing against the
shoulder 43 of the handle I0.
For attachment of the loosely fitting handle
III eccentrically to stem II a pin 45 is used. The
action of spring 4I is therefore to return the

15 From the inlet the gas enters and fills the gas to maintain the wedge 39 in any one of the
chamber I6 and passes around the bottom of notches, from which it may be released for read
the` rotor 9 into passage I1. A short duct I8 justment by manually pressing the end of handle
connects the passage I1 with a curved groove or
slot I9 formed on the face of the rotor. A 'by
pass 20 also. connects the gas chamber with
groove I9. In the adjustment illustrated in Fig.
2 the rotor is turned so that gas is being fed
to port 23 which supplies a large or high flame
burner, which it is not felt necessary to show. ‘ A
25 conduit 24 conducts the gas from port 23, to
which it has been delivered by groove or aper
ture I9, to the threaded outlet 25. A_small or
low flame burner, also not shown but which con-A
" nects directly to the valve, is supplied by gas
30 passing into port 26, and then thru outlet 21.
This port is always open when port 23 is being
supplied but may continue open after .port 23
has Vbeen closed. 'I‘he position that rotor‘slot or
groove I9 would occupy for full “off” position is
35 shown by the dotted lines on Fig. 3. The arrow
indicates the direction of movement in turning
‘the gas on, and it will be: readily seen that pört
26 can be supplied before port 23 need be turned
on, _and that when port 23 is “on” both are neces#

to pull the rotor 9 Aupward and draw the face
46 of the rotor into intimate contact with cor 20
responding face 41 of -the body so that no gas
will pass therebetween.
The stem may be non-rotatably attached to
rotor 9 by means of screw 48 and key 49. The
connection at the same time is slightly loose to
permit the. rotor faces to adjust themselves tight
ly without the necessity of stem Il being rigidly _
in 90 degree alignment with the rotor. To form
a gas tight joint without hamperingthe freedom
of thestem connection with the rotor, a cap screw
50 is screwed into the passage I1 against a
washer 5I.
For reasons particular to the adaptation -of
the device to the purpose described it is desired
to have the rotor adjustable to all intermediate 35
positions between “off” position and “low” but to
assure no intermediate adjustments between
"low" >and “high”, thereason being that lan ad
justment slightly above “low” wouldv permitgas

pending on the number of ports and outlets to be
supplied, gas may be carried to any single port
45 opening without it being Ynecessary to open any
other port and the same principle can be car
riedas far as convenience will permit a multi
plicity of outlets.
When the valve is in operation among/its com
50 mon uses is to supply fuel for generating steam
in a boiler or a combination gas and steam
radiator. If this be the case the base,5 may be
connected to the steam reservoir so that cham
ber 30 will be filled with steam under whatever
55 pressure is maintained in the radiator. As the
- pressure increases due to the continued heating
of the water in the~ radiator vitacts againsta
diaphragm 3| clamped between gaskets 32 and
spring 55 is provided, anchored at the bottom
at 55 and the top end 51 protruding through slot
58 in head piece 48.
Tension is set in the spring 55 on assembly
by twisting it the desired amount before fasten
ing head piece 40 with its 5screws 44. A pin 59
is positioned in stem I0 so that as the handle is A
turned to “low” position the pin 59 comes into 50
contact with the end of the already tense spring
55. From this position to “high” position the
rotation is constantly against the force of spring
55 so that if the handle be released in any inter
mediate position it will be immediately forced 55
back to the point marked “low”. There is a slot

tension in this position by the end 6| of slot. As
the handle is moved from “low” toward “high”
the pin 59 picks up the springend 51 and carries
it along so that if the handle is released the spring
immediately forces it back to the “low” position
where the spring movement is halted and the~
conical spring 4| snaps the handle ‘wedge into
slot 31. When the handle is finally turned to full
“high” position a similar snapping action engages
it in slot 38, where it is held until manually re
leased by tilting. At this adjustment the rotor
groove i9 opens both ports 23 and 26 allowing gas
to pass thereto from the gas chamber.
