Application March 20, 1937, Serial No. 132,004
10 Claims.
This invention relates to what is generally
known as a fountain paint brush. This application is a continuation-in-part of a prior application, Serial No. 70,092, filed March 21, 1936,
5 entitled “Fountain paint brush device.”
The chief object of this invention is to provide
a fountain brush or like device construction
which will eliminate the dipping of the brush into
the material to be applied by the brush.
Another object of the invention is to provide
for the ñowing of the paint or like from the brush
in band o1' stream form.
Another object of the invention is to arrange
the brush such that as the bristles wear the im-
mediate supply means for supplying paint to the
bristles may be adjusted in accordance with
bristle wear.
Another object of the invention is to flexibly
connect the immediate paint supply means of the
20 brush when desired, so that for certain classes of
work (other than :dat Work) flipping of the paint
due to bristle exposure of the supply means, is
The chief feature of the invention consists in
25 the construction of a fountain brush capable of
accomplishing the foregoing objects as well as all
the objects recited by the aforementioned copending application and the features specifically
disclosed herein are in .addition to the features
3.0 disclosed in the before mentioned copending application.
Still a further feature of the invention consists in providing a remote control device for the
brush and mountable upon the brush to permit
35 the brush operator to hold the brush in anyone
of several diifei‘ent manners and yet at the same
time have complete control over the paintsupply.
Another feature of the invention consists in
the addition of flared flexible tips upon the ends
40 of the bristle enclosed flexible paint supplying
tubes, which ileXible tips are also bristle enclosed.
Another feature of the invention consists in the
detachable association of the several parts so
45 that not only can cleaning of the entire brush be
effected most expeditiously and efficiently but the
tive detachable parts are of such character
that for replacement purpçses’ when
th b
e rus
bristles are worn out, there 1s required only a new
50 base with the new bristles supported thereby and
new tube tips, if necessary.
Other features of this invention will be more
fully' Sel', ÍOl’th hereinafter in the detailed description.
The full nature of the invention will be under-_v
(Cl. 15-128)
stood from the accompanying drawing and the
following description and claims:
In the drawing, Fig. 1 is an enlarged central
sectional View of a fountain brush embodying the
invention, the valve control portion being shown 5
in elevation, the dotted lines indicating the ñnal
adjustment possible when the brush is prac
tically Worn out.
Fig. 2 is a sectional view of the brush shown
in Fig. lbut is taken at right angles thereto and 10
on line 2-2 of Fig. l and in the direction of the
arrows, said brush, however, being shown pro
vided with a remote control attachment.
Fig. 3 is a view similar to Fig. 2 and of a modi
fied form of brush, the remote control attach- 15
ment being omitted for clearness.
In Figs. 1 and 2 of the drawing, I0 indicates
a base provided with a plurality of apertures II
extending therethrough, the apertures being
herein shown in alignment and parallel to each 20
other. A central aperture I3 is also provided.
The bristles I4 are suitably secured to the base.
This may be of molded rubber, or the like, if de
sire-d. The aperture I3 may be threaded to re
ceive the externally threaded tubular member I5 25
having the coaxial opening I6 therein.
Press-ñtted or molded in the base I0 and posi
tioned in the apertures II, are the tubes I1 in
ternally threaded as at I8 and terminating in a
frusto-conical mouth I9.
A head structure 20 includes a chamber 2| and
a flange 22, the latter bearing on the gasket 23
of suitable material and interposed between the
flange and the base. The head 20 is nested in a
well formed by the band 24 suitably secured to 35
and peripherally enveloping the base Ill andy pro
jecting in opposite directions therefrom to enclose
the bristles adjacent their connection to the base
and to form said Well. The head 2e is apertured
as at 25 adapted to receive a tubular portion 26, 40
the bore of the latter being internally threaded as
at 21 and Deal" its lOWel“ end being DTOVÍdSd With

by the numeral 3|, the latter terminating in a
threaded tubular end 32 which mounts a retain
ing threaded Collar. 01. nut 33_ The paint supply 50
is Connected to end 32_
A remote Control arrangement may be asso
Ciated with said Valve and the same is illus
trated in Fig. 2. It includes an apertured an
choring end 34, a hand engageable portion 35, 55
the latter portion being channel or U-shaped
in cross section and the sides 36 partially em
bracing the handle 3|. Portions 35 and 36 are
oiîset laterally and outwardly as at 31 and 38,
respectively, and thence downwardly as at 39
and 49, and the latter portion merges with the
extension 4I of the portion 39. Suitably secured
to the interior of portion 31 is a clip 42 and the
same is adapted to lie below the head of the
valve 29 while the portion 39 lies above the same.
The side portions 46 adjacent thereto thus form
with portions 39 and clip 42 a four-sided pocket
that receives the head.
This remote control attachment is readily ap
plied to the brush handle by merely removing the
nut 33 and telescoping the apertured portion 34
over the exposed threaded end 32 and in this
movement registering the remote control device
such that- the head of the valve 29 nests in the
pocket, as shown in Fig. 2. 'I'hereupon the nut 33
is replaced which secures the handle in position
and permits valve control by manipulation of
the remote control device. This permits the
brush operator to operate valve 29 to control the
supply of paint to the bristles, such control being
effected by the operator independent of the posi
tion in which he holds the brush. This device,
therefore, prevents fatigue and does not neces
sitate the brush operator always holding the
brush in a predetermined position-that is, a
position wherein the thumb always must be in
registration with the valve 39. It is to be under
stood Figs. 1 and 2 relate to the same brush, al
though the latter figure shows the addition of the
remote control attachment.
Reference will again be had to Fig. 1. In this
íigure the handle structure adjacent the valve 29
is shown provided with a shoulder 43 and between
said shoulder and the embossment 44 on the head
40 is interposed a gasket 45.
Slidably mounted in each of the tubes I1 is
a flexible tube 46.
This tube, as shown clearly
in the lower left hand portion of Fig. l, is a double
wound spring, the exterior tubular spring struc
45 ture being indicated by the numeral 46a and the
interior by the numeral 46h. The upper end of
the tubular portion supports an externally thread
ed tubular head 41 having a. diametrical slot 48
therein for screw driver engagement. If desired,
50 ’the connection between the tube 46 and the tubu
lar head may be of rotative character. In normal
operation, however, the two are rigidly associated
together. In either event, the rotation of the
tubular head secures axial adjustment of the tube
46. The limit of such adjustment is shown by
the dotted lines in the left hand portion of Fig. 1
about the middle of the ligure.
The lower end of the tube 46 is provided with
a metallic tip having the tubular portion 49 and
60 the ñattened ilared portion 56. The same sup
ports and discharges into an elongated flexible
tip structure having the tubular portion 5I and
the flattened portion 52. A split ring or lock 53
secures the metallic tip to the end of the tube 46
and when thus secured, it will be obvious that
the flexible tips are simultaneously secured to the
Whenever it is desired to yieldingly associate
the ilexible tubes together for substantial unit
70 movement and prevent undue relative movement
therebetween, the purpose for which will be read
ily apparent to painters, there is provided a ñexi
ble connection. This may be merely a leather
strip 54 apertured at 55 and the tubes 46 are posi
tioned inthe apertures. Thus, all the tubes 46
are connected together for relative unitary move
ment, although relative independent movement
within the limits 0f the tying or connecting de
vice is permitted.
Each of the apertures II is provided with a Cn
tube I1 and each tube I1 supports a tubular
structure such as last described, provided with
the ñexible leather tip 52. The central tubular
supply means is mounted slightly differently and
reference will now be had to substantially the
central portion of Fig. 1.
Tubular member I5 has its coaxial opening I6
internally threaded in the same manner as the
interior of the tubes I1 are threaded as at I8.
It also is externally threaded near its upper end 15
as at 56 and is threaded into a nut 51 embedded
or molded in the chamber exposed face of the
base I6. A nut 58 is threaded upon the opposite
end 59 of the enlarged portion I5 and bears
against the bristle supporting face of the base. 20
Thus, member I5 is rigidly locked in and to and
supported by the base I6. The tubular extension
59 terminates at its lower end in a frusto-conical
portion 60, portions 59 and 60 being substantially
similar to the bristle exposed portion of tube I1 25
and its frusto-conical end I9. The interior of
extension 59 is threaded as at 6I similar to the
threading I8 in tube I1, so that one of the flexible
tube units 46 with its tubular threaded member
48 may be associated therewith and with mem
ber I5.
» Somewhat similar to the anchorage between
the handle and the base shown in the before men
tioned application, there is herein illustrated an
anchorage as follows: Portion I5 includes an 35
opposite tubular extension 62 which may or may
not be internally threaded, as desired. It is,
however, externally threaded as at 63 to receive
the internally threaded portion 21 of the tubular
portion 26. Member I5 by reason of its threaded 40
engagements with the respective nuts 51 and
58 is non-rotatably mounted in the brush base
I0 and when the tubular portion 26 of the handle
structure is inserted in the aperture in the head
20 and threadedly engages the threaded exten 45
sion 62 of the member I5, the handle and the
base are drawn together with the gaskets 45 and
23 interposed therebetween and with the head
structure 20 between the gaskets. Thus, a closed
and relatively sealed supply chamber is provided,
paint being supplied through the tubular handle
and discharging to the tube I1 by way of the
chamber`2l fed by ports 28, the central tubular
structure being fed direct from the handle.
From the foregoing it will be obvious that,
as the several threaded members 41 are grad
ually elevated toward the base I0 to retract the
discharge ends of the tubes in accordance with
bristle wear or for flow adjustment and smooth
ness of operation, the life of the brush is de
terminable by the wear to which the bristles are
subjected and the ñnal limit of tube adjustment.
For cleaning purposes, the chamber may be
readily opened by disconnecting the handle from
the base which exposes the interior of the handle
for cleaning purposes, the head exposed portion
of the base for cleaning purposes and the head
passage and chamber. The metallic tip and the
ñexible tip may be readily detached from the free
end of each ñexible supply tube, and then if the
connecting member 54 is employed, it may be
removed from all of the tubes. Thereupon each
of the members 41 together with the tubes 46
may be unthreaded from the tube I1 and these
tubes 46 cleaned. Then the tubes I1 and 59 as
Well as the bristles may be cleaned. In this way
the entire brush may be made ready for subse
quent use with a different color or paint ma
By the terminology “paint” herein, the same
is used broadly and refers to any liquid surface
covering material that may be applied like paint,
even though not specifically of paint character,
such as for example, enamel, and the like.
In Fig. 3 there is illustrated a modiñed form
of the invention and for clearness only a portion
of the handle is illustrated and the remote con
trol attachment intentionally has been omitted.
In this disclosure, there is illustrated a base H5
15 to which is suitably secured bristles IM and the
band |24 is suitably associated therewith. A
head member |20 includes a chamber |2|. The
head member bears on a gasket |23 and bear
ing on the head member is a gasket |45. The
handle |3| having the valve structure |29 in
cludes the compression shoulder |43.
The brush shown herein is not a wide flat brush
but a single feed brush, the base HB being pro
vided with a bore H3 therethrough and having
25 suitably secured thereto the nut |57. The tubu
lar member ||5 has threaded connection with
the nut |51 and is clampingly associated with
the base by the nut |58. The tubular member
||5 includes the tubular extension |59 having
30 the frusto-conical end ISB receiving the flexible
tube |46, the latter supporting the metallic tip
|50 secured as at |53 and supporting the flexible
tip |52.
The member || 5 includes an opposite exten
35 sion |62 which is externally threaded .and is
adapted to have threaded connection with the
interiorly threaded extension on the handle |3|,
which extension is substantially identical to that
shown at 26 in Fig. l. It is, of course, to be un»
40 derstood that threaded within the tubular por
tion |59 is the threaded member 41.
While the invention has been illustrated and
described in great detail herein, the same is to
be considered as illustrative and not restrictive
45 in character. The several modifications herein
illustrated and/or described as well as others
which will readily suggest themselves to persons
skilled in this art, are all considered to be within
the broad scope of the invention, reference being
50 had to the appended claims, although the sub
