VALVE MECHANISM FOR CONTROLLING
A DRIER
George M. Gibson, Waterloo, Iowa, assigner to
National Metal Products Company, Waterloo,
Iowa, a corporation of Iowa
Application January 27, 1934, Serial No. 708,640
5 Claims.
(C1. 121-465)
This invention relates to improvements in
mechanism for operating and controlling driers,
and particularly that type of drier used in con
nection with domestic washing machines, and in
5 which is employed fluid under pressure for oper
ating the same, the drier being of that type em
ploying a rigid container in which is supported a
ilexible waterproof clothes container adapted to
receive clothes to be dried, and capable of being
10 partially collapsed to squeeze the water from the
clothes by fluid under pressure forced between
the sides of the drier and the clothes container,
suitable means being provided for discharging
the water from the clothes into the washing ma
]5 Chine.
Heretofore various types of pumps have been
used to deliver the fluid to the clothes drier for
the purpose of collapsing the clothes container.
These pumps work quite satisfactorily if proper
„D attention is given them from time to time. The
initial cost of manufacture is also quite high.
I find that a large number of the cities and
towns have water systems which operate under a
considerable pressure, varying from 30 pounds to
N) Cl 150 pounds per square inch, and that water from
the ordinary piping system such as installed in
the ordinary residence and having a pressure
above 30 pounds to the square inch may be uti
lized to advantage to provide pressure to operate
CO Ü driers of the type above described.
It is, therefore, the object of my invention to
provide a simple, durable and reliable valve
mechanism which may be used in place of the
pump for applying pressure to the drier, and in
F- connection therewith is provided a simple and
reliable means for controlling the flow of water
from the water system to the drier and from the
drier to the point of discharge, and in which is
included suitable means for easily and quickly at
40 taching the valve mechanism to the faucet of the
ordinary piping system.
A further object of my invention is to provide
an improved pressure regulating and reducing
device which may be easily and quickly attached
¿D to the ordinary drier of the fluid operated type
above described, and in which is employed a
single manually controlled device so arranged
that when the pressure reducing mechanism is
attached to the faucet of the water system, then
i
50 the operator may easily and quickly apply the
pressure to the drier when so desired, and also
accomplish the release of said pressure.
A further object is to provide in a fluid con
trolled device of the type above described, means
55T whereby a predetermined pressure within the
drier may be automatically maintained even if
the supply pressure varies considerably.
My invention consists in the construction, ar
rangement and combination of the various parts .
of the device, whereby the objects contemplated 5
are attained, as hereinafter more fully set forth,
pointed out in my claims, and illustrated in the
accompanying drawing, in which:
Figure l is a vertical longitudinal sectional
view of my improved valve mechanism showing 10
the valves in position to permit fluid under pres
sure to enter the pressure chamber, with exhaust
valve closed.
Figure 2 is a longitudinal sectional view of the
valve mechanism for controlling the flow of 15
water to and from a drier of the type above de
scribed, the valves being in a normal position
with the water shut olf from the drier.
Figure 3 is a longitudinal sectional view of same
showing the valves in the position they would 20
assume when pressure is being applied to the
drier and automatically maintained at said pres
sure.
Figure 4 is a detail end view of the lever mecha- y
nism for operating the valve.

Referring to the accompanying drawing, I
have used the reference numeral I1 to indicate
the valve casing in which one end of the pipe I5
leading to drier mechanism is connected. A dis
charge pipe I8 is connected in the upper end of
the casing Il to which a hose may be connected,
the end of which may lead to a sink or to a drain
in the floor on which the washing machine is
supported. The bottom end of the casing Il is
provided with a pipe 23 to which a suitable hose
to supply water under pressure is connected.
The casing Il is secured to the supporting
frame of a washing machine tub by means of
suitable brackets 2l. The bottom of the casing
I1 is provided with a screw threaded opening in
which is mounted a plug 29 having a vertically
arranged bearing 30. The upper end of the cas
ing I 'I is provided with a screw threaded opening
3| in which is mounted a bushing 32. The upper
end of the bushing is pro-vided with an upwardly
extending pipe 33 and having its lower end closed
and provided with an opening 34.
The casing I‘I is provided with a contracted
portion 35 having a valve opening 3B and also a,
partition 3l provided with an opening 38. The
35
40
45
50
partition 3l and the contracted portion 36 provide
means for dividing the casing into an inlet cham
ber 39, a pressure chamber 40 and a discharge
chamber 4 I. The walls of the chamber 4I have a
discharge opening 42 in which the pipe I8 is con- 55
2
2,062,126
nected, the walls of the chamber 49 are provided
with an opening 43 for receiving the pipe | 6,
while the wall of the chamber 39 is provided with
an opening 44 for receivingY the pipe 23.
Supported longitudinally through the center of
the casing |1 I have provided a valve stem 45, the
lower end of which is contracted and slidably
supported in the bearing 36. The upper end of
the valve stem 45 is provided with ahead 45 slid
10 ably mounted inthe pipe 33. The lower end of
the enlarged portion of the valve stem 45 is pro
vided with a screw threaded portion 41.
The screw threaded portion 41 supports valve
members 48, 49 and 59, said valve members being
15 formed preferably of yieldable material such as
leather or rubber. The valve members 48 and 49Y
are separated by a washer 5| and secured in posi
tion by means of suitable nuts 52, while the valve
member 56 is secured in position by means of
20
nuts 53.
`
Slidably mounted in the opening 36 is a sleeve
54 having an outwardly extending flange 55 at its
upper end designed to rest on the upper end of
the contracted portion 35 when the sleeve is at
25 its lower limit of movement. The lower end of
the sleeve’ has an inwardly extending annular
iiange 56 vfor forming a'valve seat. A discharge
opening 51 is formed in said ilange. A spring 58
has its lower end carried by the flange 56 and its
30 upper end resting against the lower end of the
bushing 32, while'a spring 59 has its lower end
' resting on the lower end of the bushing 32 and
its upper end'against the under surface of the
head 46.
35
«
`
The valves 48, 49 and 50 are supported normally
in the position illustrated in Figure Y2, with the
valve member 49 resting on the valve seat 68
formed on the upper surface of the member 31
with the valve 58 near the lower end of the charn
40 ber 39. The sleeve 54 is forced downwardly by
means of the spring 58 with its lower end termi
nating inthe chamber 40 and above the valve 48
a considerable distance.
The valve 49 is held against its seat by forcing
45 the rod>45 downwardly against the tension of the
spring 59 by means of a lever controlled mecha
nism comprising a spring 6| resting on the upper
Vend of the head 46 and placed under tension by
means of a head 62 also slidably mounted in the
50 pipe 33 andoperated by a rod 63 extending up
wardly through a packing gland 64 in the upper
end of the pipe 33.
The upper end of the rod 63 lis connected to a
Vhead 65 slidably mounted in a pipe 66 secured to
the upper end of the packing gland 64. The
upper end of the rod 63 is pivotally connected to
a link 61 forming the lower side of a lever device
68. Said lever device 68 includes link members
69 pivotally connected to the upper end of the
60 pipe 66. The member 68` is provided with an
operating handle 10. The packing gland 64 is
provided with a slidable member 1| resting on
top of the packing 12. A spring 13 has its lower
end resting on the member 1| and its upper end
65 against the head 65.
The spring 13 creates a downward pressure on
the member 1| which is slidably mounted in the
pipe 66 and thereby applies pressure to the pack
ing 12 so that a tight joint is always provided
70 around the shaft 63. The spring 13 also impartsY
a lifting force to the head 65 in such a manner as
to support the handle 10 in an elevated position
when unlocked, and in turn the head 62 also> sup
ported in an elevated position as shown in
75 Figure 3.
The links 61 and 69 are so arranged that the
shaft 63 is locked at its lower limit of movement
when the handle 10 is in its lowered position
illustrated in Figure 2, said parts being locked
with the rod 63 at its lower position of movement
on account of the pivotal connection between the
member 61 and the links 69 passing to the right
of a dead center line common to the pivotal con
nection between the links 69 and the pipe 66 and
the pivotal _connection between the link 61 and 10
the rod 63, at which time the outer end of the
member 68 will engage the upper end of the pipe
66 and thus limit the downward movement of
said lever.
When the head 62 is moved to its lowered posi 15
tion of movement, asv shown in Figure 2, pressure
will be applied to the spring 6|, which in turn
will apply pressure to the head 46 andl the rod 45,
causing the valve 49 'to engage the seat 60 with
the valve 48 spaced below the ñange 56 of the 20
sleeve 54 with the valve 5D belowthe partition _31.
This is the normally closed positions of the valves.
Assuming that the pipe 23 has been connected
to suitable water supply under pressure, then
water under pressure will enter the pipe 23 and 25
the inlet chamber 39. Assuming that it is de
sired to supply water to the drier for operating
the same, then the operator grasps the lever _10
and moves it upwardly, permitting the spring 13
to lift the head 65 to the position illustrated in 30
Figure 3, after which the spring 59 will lift the
head 46 causing the valves 48, 49 and 50 to be`
elevated to the positions shown in Figure 1, with
the valve 48 against the flange 56 of the sleeve 54.,
Water will then iiow upwardly through the 35
opening 38 and around the threaded portion of
the rod 45 into the pressure chamber 4||.v The
valve 48 will prevent water from passing through
the opening 51. Pressure will then be built up
on the pipe I6 and in the space`|5 between the
drier and the clothes container until the said
pressure equals the resiliency of the spring 5B.
Further pressure development in the pressure
chamber will cause the sleeve 54 to be moved
upwardly and in turn the valve 50 until the said 45
valve 56 engages the valve seat 14 in the mem
ber 31, at which time the ñow of water from
the chamber 39 will cease with the water in the
chamber 40 having the desired pressure to op
50
erate the drier.
When the clothes have been properly dried,
the handle 16 is then moved downwardly, caus
ing the valve 49 to be moved to position on its
seat 60 and the valve 48 Vto be separated from
the flange 56, after which water from the drier 55
will be forced upwardly through the opening 51
into the chamber 4| and from there to the dis
charge pipe I8.
'
'
Thus it will be seen that I have provided Va.control device which is of comparatively simple 60
construction and which may be easilyY attached
to a clothes drier of the type above described,
which is reliable and accurate in its operation,
and in which the entire operation of the device
may be controlled by a single lever and at the 65
same time provides means for automatically
maintaining a predeterminedV pressure in the
pressure chamber. Said predetermined pressure
may be varied by adjusting the bushing 32 in the
casing |1, said bushing being locked in its ad 70
justed position by means of a lock nut 16.
The spring 6| provides means whereby adjust
able and yieldableV pressure will always be main
tained between the valve 49 and its seat 60, even
2,062,126
if the valve seat and the valve are worn a con
siderable amount.
Sometimes it is desired to ñll the Washing ma
chine tub to which the drier is attached with
Water from the supply pipe 23. At such times the
operator simply places one end of a hose connected
to the discharge pipe I8 in the upper end of said
tub and then elevates the lever l@ a slight amount,
just enough to unseat the valve 49 without clos
Water
will then ñow upwardly through the opening 38
into the chamber 40, thence through the opening
51 into the chamber 4 l, and then into the pipe l 9
and finally to the tub I0, thereby providing means
15 whereby water may be delivered from the faucet
10 ing the valve 48 and its coacting seat.
25 to the tub without having to actuate a valve
in said water supply pipe, and thus providing a
single control for both supplying Water to a
washing machine tub and other containers.
In actual practice the diameter of the threaded
portion of the shaft 135 and the size of the open
ing 38 should be such as to provide a restricted
passage so that a considerable pressure drop will
result between the chambers 39 and ¿l5 when the
25 valves are at their maximum open position, to
3
ling the opening and closing movements of said
rod; and yieldable means for locking the rod in
its last position of movement.
3. In a device of the class described, a casing
provided with a pressure chamber having inlet
and outlet passages; a sleeve supported in the
outlet passage to slide toward or from sai-d pres
sure chamber, its inner end having a Valve seat;
