NOZZLE PACKER
Howard B. Hale, Long Beach, Calif.
Application March 2, 1936, Serial No. 66,645
1 Claim.
This invention relates to a novel nozzle packer,
by means of which the space between a nozzle
and a iiller pipe is packed off while a liquid is
being admittedv to the stock tank thru the ñller
5
plpe.
An object of my invention is to provide a novel
nozzle packer which will effectively pack off the
space between the nozzle and diiïerent sized filler
pipes.
10' Still another object is to provide a novel nozzle
packer which can be quickly and easily attached
to the nozzle and which can be so arranged as to
quickly pack oiî around the nozzle.
Still another object is to provide a nozzle
15 packer of the character stated, which is simple
in construction and inexpensive to manufacture.
Other objects, advantages and features of in
vention may appear from the accompanying
drawing, the. subjoined detailed description and
20 the appended claim.
In the drawing
~
(Cl. 285-161)
tween the nozzle and the pipe, I provide a packer
4. The packer is made entirely of iiexible mate
rial, such as rubber, and consists of a sleeve 5
which tightly grips the nozzle I. The walls of
the sleeve are relatively thin, so that the sleeve 5
can be pulled outwardly and fitted over the pipe
3, as shown at 6, in Fig. 2. If the diameters of
the nozzle I and the pipe 3 are approximately
the same, then the lower end of the sleeve 5 may
butt against the top of the pipe, as shown in 10
Fig. 1. If it is desired to have a somewhat
thicker wall at the bottom in order to pack oiî a
somewhat larger pipe, the sleeve 5 can be bent
back upon itself, as shown at> 'I in Fig. 4.
A cup~8 is integrally formed on one end of the 15
sleeve 5, and the walls of this cup are somewhat `
thicker than the sleeve 5 so that the cup will at
all times retain its shape. The cup flares out
wardly, as shown, and the outer surface of this
cup may be corrugated as shown at 9, for the 2o
purpose of strengthening the walls of the cup-,

of packing oiî around the nozzle.
nozzle I may be dropped into the pipe to a point
where the cup 8 fits into the pipe, ‘as shown in 25
_
25
Figure 2 is a. View similar to Fig. 1, showing
another method of packing off the nozzle.
Figure 3 is a view similar to Fig. 1, showing
still another method of packing oiï the nozzle,
with the same packer as illustrated in Fig. 1.
30
Figure 4 is a view similar to Fig. 1, showing a
fourth way of packing oft' around the nozzle.
Figure 5 is a view similar to Fig. 1, showing a
ñfth way in which the packer can pack: off
around the nozzle.
Referring more particularly to the drawing, the
numeral I indicates a nozzle which is attached
by means of the usual hose 2 toI a tank truck, or
the like, from which the liquid is drawn and de
posited in the stock tank, such as in a gasoline
40 service station, or the like.
The iiller pipe 3 extends into the stock tank
(not shown). These ñller pipes are of different
diameters and, consequently, there is an annular
- space between the nozzle I and the pipe 3 which
5 must be packed off in order that the liquid may
flow quickly from the truck into the stock tank.
For the purpose of packing oiî the space be
'
If the pipe 3 is quite large in diameter, the
Fig. 3. If desired, the packerrmay be reversed,
with the cup 8 extending downwardly, and then
the inside of the cup fits over the outside of the
pipe 3, as shown in Fig. 5.
The sleeve 5, as previously stated, tightly grips 30
the nozzle I and no other holding means is
necessary.
Also, with my arrangement, the packer can
easily be removed from the nozzle and reversed
for the purpose of using it as shown in Fig. 5.
35
Also, the packer can be moved longitudinally
of the nozzle to suit varying conditions.
Having described my invention, I claim:
A nozzle packer adapted to be mounted on a
ñller nozzle comprising a sleeve tightly gripping 40
the nozzle, a cup integrally formed with the
sleeve, said cup and sleeve Ybeing formed of rub
ber, the walls of said sleeve being relatively thin,
the walls of said cup being relatively thick, and
the outer surface of said cup being corrugated. 45
