6 Claims. (Cl. 15—128)
My invention relates to fountain brushes and
it has special reference to brushes that are em
ployed for washing automobiles and other ve
My improvements contemplate a brush struc
ture comprising a. hollow body of suitable out
line and preferably formed of separable parts
that are united by a common means.
Also- in
this connection I have provided novel means for
more particularly pointed out in the claims. Ref
erence is made to the accompanying drawing that
forms a part of this speci?cation.
In the drawing:--
Figure l is a view partly in side or edge eleva
tion and partly in vertical section showing de
tails of my improved fountain brush.
Figure 2 is a perspective, partly broken away
in section, of the unitary gasket and cushion or
sealing the meeting portions of adjacent parts
of the body, and I have also provided bumper
or cushioning means that prevent the brush body
contacting the vehicle or surface being washed.
Figure 3 is a fragmentary plan of the perforat
ed plate, with the bristles removed.
The drawing is to be understood as being more
The gasket o-r sealing means and the cushion or
if) bumper are a unitary integral structure so that
when the parts of the body are assembled the
cushion and the gasket will be disposed in de
sired positions without additional labor or ad
justment. This combined gasket and cushion is
preferably molded from rubber, rubber compo
sition or other comparatively soft pliable ma
The brush structure which I have invented
preferably embodies a perforated plate in which
the brush bristles are secured, which plate is
provided with outlet apertures for the discharge
and the distribution of ?uid from within the body,
and there is a. dome-shaped top co-acting with
the bristle plate to provide a chamber within
30 the body.
The gasket member is compressed
between the plate and top in a position to dis
pose the bumper peripherally around the outer
edges of these parts. Fluid is supplied'to the in
terior of the hollow body by means of a tubular
.- handle connected with a source of water supply.
The assembly of the parts is such that they are
readily separable so that the brush member and
gasket may be renewed whenever desired.
In devising my improvements I have numerous
objects in mind among which may be mentioned
that I have produced an article of this character
that is novel in construction; is dependable in
performing the functions for which it is designed;
is made of sturdy parts to withstand hard usage;
45 is made of few parts which require but a single
operation to assemble; and is economical to man
ufacture so that it may be sold at a resonable re
tail price to the user. Other objects and advan
tages of my improvements will be apparent to
50 persons skilled in the art after the construction
and operation of the device is understood from
the following disclosure.
I prefer to practice my invention, and to ac
complish the objects thereof, in substantially
55 the manner hereinafter fully described and as
or less schematic for the purpose of disclosing a
typical or preferred form in which my invention 15
may be made, and in the drawing like reference
characters identify the same parts wherever said
parts appear in the different views.
The body of the brush comprises a bristle plate
5 and a top member 6 that are maintained in de 20
sired relation to each other by common means
that urges these parts towards each other. The
plate 5 as well as the top member 6 may be of
any suitable outline, such as circular, oval, tri
angular, or rectangular, and said plate is pro 25
vided with a plurality of seats ‘I in which the
bundles of bristles 8 are secured in any suitable
manner so- that they project from the outer face _
of the plate. 5. The said plate is also provided with
a plurality of outlet openings or passages 9 that 30
permit ?uid to pass through the plate from one
side to the other.
The top member 6 embodies a central dome
shaped portion Ill that arches upwardly to pro
vide, with plate 5, an internal chamber H, and
at the center of the dome-shaped portion there
is a hollow stub that depends centrally there
from. This stub I2 is interiorly threaded to re
ceive the threaded shank 13 of a bolt that passes
through a central aperture l4 in the bristle plate 40
5 so as to provide common means for drawing
the two parts together Beyond the edge of the
upwardly extended dome-shaped portion the top
member 6 is provided with an annular rim l5
that is preferably flat and is disposed in parallel
relation to and opposing the marginal portion
of the bristle plate 5.
A suitable gasket, shown in detail in Fig. 2, is
interposed between the rim 15 of the top member
and the opposing marginal portion of the bristle
plate 5. This gasket is preferably in the form of
a ring-like ?ange iii of slightly greater width
than the rim l5 of the top member, as seen in
Fig. 1. The lower face of the gasket I5 is pref
erably a plain surface, while the upper face is 55
somewhat channel-shaped in cross section. This
channel formation is accomplished by providing
a small upstanding bead I‘! at the inner edge
of the ?ange 16 that is of su?icient height to ex
tend upwardly into the lower portion of the
dome-shaped part of the top member at the in
ner edge of the rim IS. The outer portion of the
gasket I6 is preferably connected to the inner
annular face of a substantially vertical disposed
10 buffer or cushion IS.
The gasket ?ange I6 is
preferably molded integral with a buffer or a
cushion l8 and extends from the inner face there
of intermediate and spaced from the edges of the
buffer. As will be seen in Fig. l, the vertical
dimension of buffer I 8 is slightly greater than the
combined dimensions of, the plate 5, the gasket
[8 and the rim I5, so that the upper and lower
edges of the buffer extend respectively above and
below the rim and the plate a distance to prevent
the metal parts contacting the surface being
washed and marring the ?nish thereon.
From theforegoing it will be seen the struc
ture comprising the bristle plate 5, the gasket and
buffer, and the top member 6 are superposed upon
each other and are secured together by common
means in the form of a bolt l3 and when the parts
are being assembled, the one upon the other in the
manner shown, the turning of the bolt will cause
the gasket to be compressed between the margin
of the plate 5 and the annular rim [5 of the top
member. This also securely anchors the buffer
and cushion in a position outside the edges of the
plate and top member where it is in position
to be engaged with the surface of the vehicle
being washed, thus avoiding contact of the edge
portions of the brush structure with the ?nished
' surface of the vehicle.
Water is supplied to the
interior chamber I I through a tubular handle [9
that has its lower end screwed into an enlarge
40 ment 2!] that is bored and threaded to receive
said handle. It will be understood that with the
construction herein disclosed the brush plate and
its bristles and the gasket may be readily renewed
by unscrewing the bolt to cause the separation of
the respective parts.
What I claim is:
l. A fountain brush comprising an apertured
plate, bristles secured to said plate and extending
from the outer surface thereof, a top member
50 having a dome-shaped central portion and an
