This invention relates to a sprayer construction
and particularly to a sprayer ot the type which
may be carried by the operator and in which the
fluid is placed under pressure by air.
.
It is desirable in such a sprayer to have a recep
therein. This opening` must be closed during the
spraying operation and it is desirable to have a
"10 simple means and one which may be easily and
quickly operated to tightly close thesaid opening
and receptacle. A pump >cylinder for pumping
air is provided and it is desirable to have the
handle which operates the plunger' rod of the
pump or pump 'cylinder also used for eifecting
said closure.
It is an object of this invention, therefore, to
provide a simple and efficient type of receptacle
adapted to receive the spraying iiuid.
`
It is aV further object of the invention to pro
vide a receptacle having a comparatively large
opening for the reception of the spraying fluid
together with simple and easily and quickly op
erated means for closing said opening.
It is still another object of the invention to pro
vide a sprayer having an air pump cylinder with
a plunger rod equipped with a handle, said handle
also being constructed and arranged to be used in
effecting the closure of the receptacle.
30
It is still further .an object of the invention to
provide a sprayer comprising a receptacle having
an opening at its upper end surrounded by a
gasket-receiving surface, a closure plate carrying
a gasket adapted to engage said plate and rotat
able means for pressing said gasket against said
surface without rotating said gasket.
These and other objects and advantages of the
invention will be fully set forth in the following
description made in connection with the accom
panying drawings in which like reference ‘charac~
ters refer to similarparts throughout the several
views and in whichz--
o

_
Fig. 3 is la partial view in side elevation of the
closure means together with a portion of the
pump cylinder and the pump plunger rod and
handle;
Fig. 4 is a horizontal section taken on line fi-ll
of Fig. 3 as indicated by thearrows;
Fig. 8 is a top plan View of the container.
Referring to the drawings, a sprayer is shown
comprising a receptacleV lil and while various lO
forms oi receptacles might be used, in the embodi
ment of the invention illustrated the receptacle
it is shown as an upright cylinder having beads
lila adjacent its tcp and bottom and having a
cup-shaped portion iilb at its top. The portion
lill; is open at its upper' end and the side wall
thereof forms an upstanding rim, the
being
shown as having an outwardly turned bead lilo
at its upper edge. A short distance inwardly of
the side wall of portion illb the same is formed
with a plurality of partly circular helical flanges
ltd, said iianges being partly circular as shown
in Fig. 8. The upper part ille of container EEB
upon which portion itil) seats and to which it is
secured, extends inwardly horizontally and is pro- f
vided with a` central opening lilf of comparatively
large diameter, which opening is surrounded by
a bead ity struck up from portion ille. A closure
plate l l is provided carrying at its central portion
a pump cylinder i2 which extends downwardly
below said plate into receptacle it and which has
its open upper end projecting some distance above
said plate, said upper end being provided with
an outwardly extending bead läd. The plate H
at its outer portion’is bent to forni an annular :3,:
trough in which is seated a gasket member i3.
The bead its forms a gasket-receiving surface or
a seat for gasket i3 which engages the saine to
form a tight closure. A second plate lf2.- is pro
vided, which plate is formed at its outer edge with . i
a plurality of partly circular helical ilanges lila
adapted to cooperate with flanges läd. It will be
seen from Figs. 4 and 8 that said ilanges have ad
jacent ends, the high portion of one flange being
adjacent the low portion of the other ñange and f .
disposed some distance'above the same.
With
this arrangement the flanges lila may have their
ends enter below the flanges illd and in the rota
tion of plate lli the same will be drawn down
wardly toward the receptacle by ñanges ind.
Plate ill engages the top of plate le! adjacent the
outer top portion of the latter and is adapted to
press plate il downwardly as plate irl is rotated.
Plate lil has: an upwardly pressed central portion
Mb forming a substantially cylindrical recess at
à
2,111,961
its lower side adapted to receive the upper end of
the pump cylinder I2. The wall surrounding said
recess has circumferentially spaced resilient por
tions Ific separated a distance slightly less than
UI the diameter of the bead IZa. As shown in Fig. 7
these portions are straight portions at opposite
sides of portion I 4b. The bead I2a and thus the
upper end of pump cylinder I 2 must be forced
past portions Ille with considerable pressure to
be received in the recess in portion Mb.
The
pump cylinder and thus plate II are then con
pump the air through cylinder i2 and into the
nected to plate Iâ against longitudinal separation
receptacle I5. After the desired air pressure has
been attained the handle I6 can again be moved
to insert lugs itc through the slots Md and said
lugs may be moved to the ends of said slots. The
sprayer can then be carried by means of handle
I6 if desired. The member iâlb forms in effect a
funnel and prevents spilling of any liquid which
might not at once enter the opening IElf, The
or movement by any ordinary force but are ro
tatable relatively to plate It. Said parts may
be separated by a longitudinal pull thereon with
the application of considerable force. Member
it has a central opening through which extends
a plunger rod I5 extending into pump cylinder
I2 and which will be provided at its lower end
20 with the usual plunger for the air pump. Rod
I5 has a handle I6 secured to its upper end and
while this handle might be variously formed, in
the embodiment of the invention illustrated it is
shown as having upwardly curved sides rectilinear
and parallel at their upper portions and connected
by horizontal portions Ilia. Portions Ita are also
shown as connected by a ’central portion I 6b hav
ing oppositely disposed concave sides. Plate I4
at either side of rod I5 has curved slots Idd, the
30 same having at their centers outwardly extend
ing enlargements Ille. 'I‘he top of portion Mb is
also pressed upwardly at portions IM at the ends
of said slots and at their outer sides to form
small recesses on the underside of said portion.

lilo. Owing to the provision `forrelative rotation
between the upper end of the pump cylinder and
plate It the plate I I need not rotate so that there
will be no rotation of gasket I3. This is desirable
as it is objectionable to rotate the gasket on its Ul
seat. The sprayer is now tightly closed and the
desired air pressure can be placed on the liquid by
slightly rotating handle I6 so that the lugs IIic
can be withdrawn through slots Idd and enlarge
ments Ille and the handle then reciprocated to 10
Handle I6 has projecting downwardly from its
lower side at each side of rod I5, lugs IIìc and
these lugs have outwardly extending portions or
projections läd with fiat top surfaces. In Fig. 1
the sprayer is shown as having small brackets I'I
secured in vertically spaced relation along one
side in which are connected the rings I8, in turn
pivotally connected to clips I9 secured to the
ends of a supporting strap 20 which the operator
may place around his shoulders. A portion of
the discharge tube 2| for the sprayer is also
shown in Fig. l.
In operation, when the sprayer is to receive the
spraying fluid, the lugs ,i60 will be placed down
wardly through the slots Idd through portions
Ille. Handle I5 will then be rotated in a counter
clockwise direction and the projections läd will
move under the top of portion Mb and said lugs
will engage the ends of slots Iâd and rotate plate
ill. Said plate will be rotated to bring the helical
flanges Illa out of engagement with the flanges on
the top of container IIJ. Handle I6 will then be
lifted and at this time the projections iSd will
seat in the recesses formed at the undersides of
portions IM. Plate I4 and plate II, which, as
60 stated, is connected thereto, will now be lifted and
removed together with pump cylinder I2. The
spraying fluid can now be poured into opening
Ilìf- When the desired amount of fluid has been
placed in the container the plates Il and Irl to
65 gether with pump cylinder I2 will be again placed
portion Iüb being permanently secured to the 20
container is always available and a funnel is
always thus in place for use.
From the above description it is seen that ap
plicant has provided a very simple and efñcient
structure of sprayer and particularly of the 25
closure means for the sprayer. The structure is
very compact and comprises very few parts. The
filling of the container can be easily and quickly
done and the sprayer quickly put in condition for
use. lI’he device has been amply demonstrated in 30
actual practice and found to be very successful
and efficient.
It will, of course, be understood that various
changes may be made in the form, details, ar
rangement and proportions of the parts, without 35
departing from the scope of applicant’s invention,
which generally stated, consists in a device capa
ble of carrying out the objects above set forth in
the parts and combinations of parts disclosed and
defined in the appended claims.
