Application March 7, 1935, Serial No. 9,722
6 Claims. (Cl. 226-127)
My invention relates to tubes for transferring the mechanism outlined herein and covered by
fluids and to valve mechanism therefor and more
particularly to such devices for transferring fluids
from a source of supply to a place of discharge
5 such as a tank', tube, or other receptacle to bei ñlled to a predetermined level or to be ñlled with
a predetermined amount of ñuid.
'I‘he general type of device to be described here
in is similar in many respects to those described
lo and claimed in patents previously issued to me
and in applications which are now pending in
myäname in the Patent Oflice.v However, the
device of the instant application is one which is
simple and, therefore, may be manufactured
l5 easily and cheaply and, in addition, the present
device differs in other respects, as set forth below,
from the various embodiments of my basic inven
tion.
In a device embodying my present invention
„o the trigger mechanism for cooking the valve into
open position has been dispensed with and the
structure is greatly simplified. The valve is moved
into open position by a part engaging the mar
ginal surfaces of the receptacle adjacent the
.25 opening through which it _is filled. Also, in em
bodiments of my device, as heretofore used by
me, the passage through which the fluid _passed
was constricted to form a Venturi >opening soÁ
that the increased rate of ñow of the fluid through
30 such constricted opening would cause a. suction
. which,> when the port for an equalizing ñow of
air was closed, would cause the valve to close by
movement of a diaphragm. In embodiments of
the claims.
In the drawing, wherein similar characters are
used to designate 4similar parts, Fig. 1 is a sec
tional vicw through the nozzle; Fig. 2 is a cross
section along thel line 2-2 in Fig. l; Fig. 3 is a
section along the line 3_3 in Fig. 2; and Fig. 4
is a partial section along the line 4-4 in Fig. l.
Referring to the figures the nozzle shown
therein as embodying one form of my invention 10k
comprises a. casing I which, for cheapness of
manufacture, is preferably cast in one piece'so
as to include an upper cylindrical extension 2
forming a valve chamber communicating with
the hollow interior 3 of the casing proper and 15
a lower extension 4 from which extends the out
let tube 5 and its axially movable sleeve 6, for
the purposes outlined below. The casing may
_be made of any suitable material, but is prefer
ably cast of aluminum or other durable and light 20
metal.
.
Arranged, preferably, centrally of the casing
in thehollow interior 3 is a block 'I which is drilled
to receive a freely rotatable shaft 8. The shaft
near the inner end thereof is cut or otherwisev A25
formed with a reduced cam surface 9. The shaft
8 is maintained in'position and prevented from
longitudinal movement by a pin IB projecting
beyond the circumference thereof at diametrically
opposite points positioned between the shoulder 30
II formed on the block 'I and a nut I2 threaded
into the body of the casing I. The nut I2 pref-`
erably has a recessed portion to receive a pack
this invention the valve opening has the seat ~ ing material such as graphite as indicated at I3
35 thereof formed to provide a constricted opening
through which the iiuid passes and the velocity
of the fluid passing through the valve opening
and past the valve seat causes a suction similar
in all respects to that heretofore caused by the
40 Venturi tube.
'
Furthermore, often it is desirable that the
valve be automatically shut off to prevent further
flow of iìuid when a predetermined amount of
fluid has been transferred tothe place of dis
45 charge and, therefore, my present invention pro
vides means for so stopping the ñow.
In the accompanying drawing I have shown
my invention to acomplish the above and other
objects as embodied in a filler spout nozzle formed
50 as a part of a tube for dispensing liquid such
as gasoline into the fuel tants of an automobile.
However, it is' to be understood that this em

its broad

and a packing nut I4 threaded into the inner 35
surface of the nut I2 whereby the packing ma
terial may be, conñned and whereby fluid passing
through the nozzle will not ñnd its way into the
bore of the block l. In manufacturing the de
'vice the shaft 8 and its packing may be assem- 40
bled and the unit may be inserted into place by
turning the nut I2 into the threaded portion of
the casing body.
Opening between the valve chamber 2a in the
extension 2 of the casing and the hollow interior 45
3 thereof is a valve opening I5 which has the
sides thereof -inclined inwardly in the direction
of flow therethrough or which is otherwise formed
toprovide a constricted opening through which
passes fluid being dispensed by the nozzle. Pref
erably the valve op
is formed so that ‘the
constricted part p1. tents a seat for a valve I6
of the usual type. The valve I6 is carried by a
guide rod I1, one
of which is slidably mount
ed in a boss I8 and the other end of which ex» 5,.'

The means forvso rotating the shaft.8 to open
the valve iscontrolled by movement of the slid
ing sleeve 6 along the outlet tube 5 of the nozzle.
The tube 5 is threaded in the body of the casing
15 I as at 2| and the`»\lower extension4 of thecas
ing is vbored out to provide an annular opening
around the tube. The inner end of the sleeve
6 isprovided with a shoulder 22 and the sleeve
is prevented from moving too ` far outwardly
20 along the tube 5 by a nut~23 threaded in the ex
45 .which is freely rotatable about the shaft 8
and which is, in this embodiment, normally im
pelled in: a clockwise direction by a spring 46.

as at 48`to receive the end 44 of the bell crank

mechanism therefor.
