LIQUID DISPENSING DEVICE
George B. Davis, Jr., Washington, D. 0.
Application June 22, 1937, Serial No. 149,762
4 Claims.
This invention relates to a liquid dispensing
device designed primarily for use with the type
of measuring apparatus used at ?lling stations
for dispensing liquid fuel to automotive vehicles,
.5 but it is to. be understood that the device, in
accordance with this invention, is for use in any
connection for which it may be found applicable,
and the invention has for its object to provide,
in a manner as hereinafter set forth, a device
“10 of the type referred to so constructed and ar
ranged to provide for a variable ?ow of the liquid
therefrom when occasion requires.
A further object of the invention is to provide,
in a manner as hereinafter set forth, a device
~ 3:5
of the type referred to which may be expeditious
1y secured ‘to the regular standard ?exible hose
leading from the liquid measuring apparatus.
A further; object of the invention is to provide,
in a manner as hereinafter set forth, a device
of the type referred to including a nozzle coupling
portion, a combined valve chamber and handle
part and a shiftable- spring controlled manually
operated Valve controlling means depending from
said part and arranged forwardly of the front
. 25
of the handle for controlling the dispensing ac
tion of the device.
Further objects of the invention are to provide,
in a manner as hereinafter set forth, a device
(Cl. 221-84)
be resorted to which fall within the scope of the
invention as claimed.
In the drawing:
Figure 1 is a side elevation of the device in
stalled with respect to a liquid conducting line
leading from a source of supply,
Figure 2 is a vertical sectional view of the
device with the nozzle element thereof removed,
Figure 3 is a section on line 3—3, Figure 2,
and
10
Figure 4 is a top plan view of the controlling
lever partly in section.
The device includes a casting l formed of
any suitable material channeled from end to end
thereof.
The casting I consists of a nozzle cou
pling portion 2, a valve chamber portion 3 and
a handle or hand grip forming portion 4. The
portion 3 couples the portions 2 and 4 together
and is substantially of elbow-shape in length
wise section. The portion 2 is straight. The
portion 3- inclines rearwardly and depends from
the rear end of the portion 3. The channel which
extends from end to end of the casting I has
the part 5 thereof arranged in portion 4, part
6 thereof arranged in portion 3, the lip or part
1 thereof arranged in portion 3 and the part 8
thereof arranged in the portion 2. The part 8
merges into the forward end of the part ‘I and
for the purpose referred to which is simple in its Y the rear end of the latter merges into the for
l. 3.0
construction and arrangement, strong, durable,
compact, readily assembled, thoroughly et?cient
ward end of the part 6. The upper end of part
5 merges into the other end of part 6. The part
in its use, conveniently and expeditiously Opel‘?
ated to provide a liquid dispensing function and
5 is disposed at an inclination with respect to
the part 6. The latter is of ‘curved contour and
has its forward portion arranged above the rear
of part 'I'. The part 8 is straight and opens at
the rear end of its bottom into part 1. The
part 8 is of greater diameter than the parts 5, 6
and ‘l. The portion 3v of casting I. has an integral
depending web 9 between the parts In and II of
such portion. The web 9 aligns with the longi
tudinal median of portion 3 and is spaced from
the side faces of the latter. The forward end‘ of
the wall of part 6 of the channel is bevelled as at
[2 to provide a valve seat arranged at the top
of part 1 of the channel and within the portion
3 of the casting. Directly below and spaced from
the seat l2 the part I0‘ of the portion 3 of the
casting is formed with a vertically disposed valve
chamber I3 which opens into the part ‘I of the
comparatively inexpensive to manufacture. The
.35 channel is of large size at the inlet end where it
connects with the supply pipe and gradually de
creases in size throughout its length to the valve
below described, and just beyond the valve is
also. of small size, from whence it is greatly and
40 immediately enlarged and so. continues. to the
exit. The result of this structure is that toward
the‘center oi“v the device the flow is choked back
and decreased in volume, but due to the enlarge
ment ofv the exit a free passage is provided and
45 the ?ow not forced out but allowed to move
quietly whereby turbulence and splashing‘ is
prevented.
'
.
To the above ends essentially and to others
which may hereinafter appear, the invention
50 consists of the novelv construction, combination
and arrangement of parts as will be more spe
ci?cally described and illustrated inithe accom
panying drawing; wherein is shown an embodi
ment of the invention, but. it is to be understood
155 that changes, variations and modifications may
channel and also opens‘ at the bottom of the
part ill of portion 3 of the casting. The outer
portion of the wall M, of valve chamber I3 is
threaded as at [5 and engaging therewith is an
outer packing gland l6 formed at its inner end
with an inwardly extending annular flange 11,
2
2,127,860
and at its outer end with an outwardly directed
annular flange l8. The gland I6 is interiorly
threaded and engaging therewith is a peripher
ally threaded inner packing gland l9 having an
external ?ange 2D abutting ?ange l8.
Extending through the glands l6 and I9 is a
stern 2| formed with a circular head 22 of a
diameter to snugly engage the wall M of valve
chamber |3. Fixed to the top of head 22 is a
bevelled disc-shaped valve 23 adapted to engage
the seat |2 for the purpose of closing part 8 of
the channel to part 1 0f the latter. When the
valve 23 is off its seat, communication is estab
lished between the parts 6 and ‘| of the channel
of the casting. The stem 2| is of a length to
project beyond the gland l9 and carries at its
outer end a diametrically extending pin 24. In
terposed between the flange ll of gland l6 and
the inner end of gland l9 and surrounding stem
2| is a packing 25.
The device includes a nozzle 26 which is inte
riorly threaded and engages with the peripheral
threads 2'! formed on the portion 2. The latter
has an annular stop or rib 28 on its periphery on
the inner end of the threads 21.
The device includes a shiftable spring con
trolled manually operated controlling lever 29 for
the valve structure consisting of the stem 2|,
head 22 and disc 23. The lever 29 is of angle
form and consists of an upper horizontally ex
tending leg 30 and a vertically disposed leg 3|
depending from the inner end of the leg 39. The
leg 30 has a bifurcated forward end 32 provided
with aligning slots 33 and at its rear end is formed
with a pair of ears 34 having aligned openings
35. The inner face of the leg 3| is formed with
a groove 36 extending lengthwise thereof. The
pin 24 projects laterally in opposite directions
from the stem 2| and is slidably mounted in the
The lower end of the stem 2| is posi
tioned in the bifurcated end 32 of the leg 39.
The web 9 is formed with an opening 31 which
aligns with the openings 35. A pin 38 extends
40 slots 33.
through the aligning openings 35, 31 for pivotally
45
connecting the rear end of the leg 39 to the por
tion 3 of the casting I.
The forward side of the portion 4 of casting I
has a groove 39 lengthwise thereof and which
opposes the groove 36. Arranged between the
leg 3| and the front of the portion 4 of casting
| is a spring 49 formed of a looped part 4| and
a pair of end parts 42, 43 extending'in opposite
directions with respect to each other. The end
part 42 bears against the wall of the groove 36.
The end part 43 bears against the wall of the
groove 39. The spring 40 functions to normally
maintain the valve structure in position to shut
off communication between parts 6 and ‘l of the
channel in casting |.
The valve structure is slidably connected to the
60
lever 29 or in other words, there is a loose sliding
connection between the lever 29 and the lower
end of the stem 2|. When rearward pressure is
exerted against the leg 3| of lever 29 the leg 33
is lowered which in turn will force the valve
structure downwardly and the extent of the shift
will provide for varying the flow of the discharge
of the liquid from the casting | into the nozzle 25.
With reference to Figure 1 a ?uid conducting
line is indicated at 44 and is attached to the por
tion 4 of the casting |.
The disc 23 is to be constructed of any suitable
material and is anchored to the head 22 by the
holdfast means 45.

ing including an intermediate portion, a forward
