DEVICE FOR APPLYING GRANULAR
»MATERIALS
Orlando D. Shonnard, Upper Montclair, N. J.,
assigner to Joseph Dixon Crucible Company,
`lersey City, N. J., a. corporation of New Jersey
Application January 14, 1937, Serial No. 120,547
9 Claims. (ci. zei-32)
The invention relates Vto' an improvement in
devices for applying granular materials to sur
faces, and more especially to devices for apply
ing iinely divided-materials, such as powdered
5‘1 graphite, plumbago, and the like, to surfaces to
be lubricated or protected from the action of >the
atmosphere and other deleterious action. More
particularly the invention relates to an improve
ment in such devices provided with` means for
10T opening and shutting the nozzle.
It 'has been proposed heretofore to provide noz
zle `controlled devices for expelling ñnely divided
materials, in the form of a small cloud, as to
surfaces requiring lubrication or protection, and
«15' several such devices, some of them patented, have
appeared on the market. Although the attempt
has been made to satisfy the demand for such
devices, especially> those for applying powdered
graphite, the devices which have> heretofore ap
peared have not been entirely satisfactory for all
20 uses, since their construction has involved ex
penses requiring a retail price beyond that of
many purchasers. Hence, there has arisen a de
mand for a device of this character which can
_, be produced at low cost and so sold to the trade
unable to purchase the more elaborately con
structed devices for applying finely divided mate
rials.
,
' One object of the present invention is to pro
_ , duce an improved and simpliñed device for expel
‘50 ling from a reservoir finely divided material when
needed, such as powdered graphite or the like
to surfaces requiring lubrication, or protection
from the action of the atmosphere or the action
_ of other natural elements.
A further object of
the invention is to produce a device of this char
acter of such construction that it can be manu
factured cheaply and so be sold at retail at prices
within the range of the purchasing power of large
numbers of persons who cannot afford to pur
chase the more expensive and elaborate devices
of this nature heretofore placed on the market.
Another object of the invention is to provide such
devices with improved means for controlling the
‘_- expulsion of the powdered ,materiaL Another
object of the invention is to produce a 'device of
this character having provision for ready removal
of the nozzle assembly for refilling and cleaning
purposes, should those occasions arise. To these
' ends the invention consists in the improved de
vice for applying finely divided’ materials here
inafter more fully described and particularly
pointed out in the appended claims.

In the accompanying drawing illustrating the
preferred form of- the' invention,- Fig. l'is a side
elevation of the improved device for applying 1
granular materials, with the nozzle turned to open
position; Fig. 2 is a View of the upper part of
the device shown in Fig. 1, but with the nozzle
turned to closed or shut position; Fig. 3 is a top 5
plan of the device shown in Fig. 1; Fig. 4 is a
longitudinal section, on an enlarged scale, taken
on the line 4-4 of Fig. 1, and showing the nozzle
in open position; Fig. 5 is a View similar to Fig.
4, but with the nozzle in closed position; Fig. 6 10
is a transverse section taken on the line 6_6 of
Fig. 4; and Figs. 7, 8 and 9 are views-similar to
Fig. 4, of modified forms of the invention.
The improved device for expressing and apply
ing ñnely divided materials, such as applying 15
powdered-graphite or other'granular materials
to surfaces, as illustrated in the drawing, com
prises an elongated resilient cylindrical reservoir
I0, which may conveniently be composed of any
resilient material, such as Celluloid, closed at its
inner or lower end II and open at its outer or 20
upper end I2. In the open end I2 of the cylin
drical resilient reservoir I0 is located a plug or
stopperk|4 composed of a resilient material, such
as cork. The resilient plug I4 has a smooth cylin
drical exterior to i’it tightly in the outer end of 25
the reservoir, and flat inner and outer faces.
The plug I4 may be permanently secured in the
open end-of the reservoir I0, as by cementing,
or it may be tightly but removably located there
in, being secured against accidental removal 30
therefrom by any convenient means such as the
nail` I3.
In thepreferred form of the 'invention illus
tratediin Figs. l to 6, the plug I4 is provided
axially throughout its length with a cylindrical
bore adapted to'receive snugly but rotatably the
tubular inner part or extension I5 of a nozzle
assembly consisting of the conical tubular nozzle
proper Il provided at its inner end with a disk- 40
like collar I6 having a flat inner face adapted to
seat against the outer end of the reservoir I 0 ‘
and adjacent to the outer face of plug I4, as
shown in-Figs. 4 and 5. From the center lof the
collar I6 the conical tubular nozzle I1 extends
outwardly, having a contracted oriñce I9 in its
outer end.
The inwardly extending portion rI5
of the nozzle assembly constitutes an inner pro
longation of the nozzle I1. The disk-like collar
I6 is provided atits outer edge with a rearwardly 50
extending annular ñange IB which snugly but
rotatably embraces the exterior surface of the
outer end of the reservoir I0 so that the nozzle
structure as a whole, composed o_f the parts I5,
I6, I1 and I8, may be rotated,

It has been found desirable in the operation
of devices like that of the present invention, for
expressing from a container or reservoir ñnely
divided materials, such as powdered graphite, to
provide means for preventing the expulsion of
the material except when needed. -To this end
the device of the present invention isprovided
with novel means for permitting the expression

pose a plate 28 secured against the lower or in
ner face of the plug I4 is provided with a hole
40 29 (of substantially the same size as or smaller
than the hole 22) , which permits only restricted
quantities of the material 26 to pass into the re
cess 24 when the resilient sides of the reservoir
are squeezed, thereby preventing clogging of the
45 ducts of the device.
From the recess 24 the
granular material passes outthrough the aper
ture 22 and the orifice I9.
’
Plate 28 is preferably of a stiff, compression
resistant material, such as fiber or metal, having
50
an external diameter slightly less than the in
ternal diameter of the cylindrical reservoir I0.
At its central point the plate 28 is perforated to
receive the inner extremity of the nozzle part I5.
The plate 28 may be secured to the inner face of
the resilient plug I4 by any convenient means,
as by cementing, or by the nails 30. It is well
known that although cork is resilient, and may
be easily compressed, it does not tend readily to
return to its former size or position, and that
60
after repeated compressions it is appreciably
smaller than its original size. In order to pre
vent the inner end of the resilient-plug I4, which
is conveniently composed of. cork, from being
compressed into a permanently less size than
65 its original diameter, the present inventionpro
vides at the end or face of the plug I4, the plate
28 which resists the inward compression of the
outer end of the reservoir I0,\when the middle
portion thereof is squeezed to express the ñnely
70 divided material from the reservoir.
In this
manner the original size of the resilient plug I4
is preserved and it continues to fit tightly in the
open end of the reservoir throughout the active
service of the device.

In the modified formI of the invention shown
in Fig. 8, the inner tubular portion 45 of the 40
nozzle 46 is provided with a cup-shaped sealing
plug 41 having a lateral flange 48 which over
lies not only the inner end of the tubular por
tion 45 of the nozzle but ‘also the adjacent inner
part 49 of the plate 50, which construction pre 45
vents the removal of the nozzle 46 from the de
vice unless the fastening means such as the
nail 52 for preventing accidental removal of the
plug 53 fromv the outer end of the reservoir Il) is
ñrst taken out. The plate 5I) shown in Fig. 8 50
may conveniently be held against the inner face
of the plug 43 by the teeth 55 turned outwardly
from the plate itself. In respects other than
those described above, the fo-rm of the invention
shown in Fig. 8, is similar to that shown in Figs.
4 and 5. It will be understood that the nozzle
assembly: shown in Fig. 8 constitutes with the
resilientl plug 53 a unitary structure for removal
from and reinsertion in the open end of the
60
reservoir.
The device of the present invention for apply
ing iinely divided materials on surfaces, because
of its simplicity of construction and consequent
low selling price, justiñes its cost when the ma
terial, such as powdered graphite, contained 65
within the reservoir I0 is used up. The empty
device can then be thrown away. With the more
frugally minded,lhowever, there is a demand for
reñllable devices. Those illustrated in Figs. 1
to 8 may all be reñlled by removing the means 70
holding the resilient plug in the open end of
the reservoir and then by one means or another
abstracting the sealing plug. However, these
forms ofthe invention are not particularly adapt
ed- for ready ‘removal of the sealing'plug from 75
2,106,470
the reservoir’.
A more vconvenient means of re~'
moving the sealing plug for refilling the reser~
Voir is shown in the modified form of the in~
vention illustrated in Fig. 9, which is substan
tially the same in construction and mode of op~
eration as the form of the invention shown in
Figs. 1 to S, except that the resilient sealing plug
5l is shown provided with an outwardly extending
part $4 the outside diameter of which is sub
stantially the same as the outside diameterof
the cylindrical reservoir l0, and is provided with
a shoulder 59 which seats against the outer open
end of the reservoir l0. In this form of the in
vention the slightly conical collar 60 of the noz
zle 6| terminates at its outer edge 63 flush with
the periphery of the outer end 64 of the resilient
plug 5l, thereby providing an area which may
be grasped by the fingers of the user and so be
readily pulled out of the reservoir Ill, after re
20 moving the fastening means, such as the nail
65, which holds the resilient plug 51 against ac
cidental displacement from the reservoir Iü. In
this connection, it will be understood that the
cooperation of the resilient materials of which
25 the reservoir and sealing plug are composed hold
the plug tightly in the reservoir, and that the
auxiliary fastening means, such as the nails
shown in the various modiiications of the inven
tion are only provided to secure against acciden
30 tal removal of the plugs. `It will be understood
further that in those cases in which the resil
ient sealing plug is not to be removed from the
reservoir, it may be permanently secured therein,
as by means of cement or the like without the
use of mechanical fastening means.
Whether the resilient sealing plugs are'per
manently or removably secured in the reservoirs,
the nozzles may or may not be permanently con
nected with the sealing plugs.
The nozzle as
40 semblies shown in Figs. 4, 5, 7 and 9 provide
a convenient arrangement for the ready removal
of the nozzle assembly only,- without the plug, in
case is should be desired to clean out the ducts of
the nozzle.
