Divided and this application Mar. 19, 1964, Ser. No. 353,655 Ciairns. (Ql. -547) This application comprises a divisional application of my copendigg application, Serial No. 135,230, for Combined Paint Pump and Roller Applicator, filed August 31, 1961, now Patent No. 3,135,005.
This invention relates to a novel and useful combined paint applicator and handle pump and more specifically to a paint applicator of the brush type and including a handle portion with the brush portion thereof including a flexible paint reservoir enclosed Within the brush bristles thereof.
The paint applicator of the instant invention may or may not be provided with a paint pump in the handle portion thereof but is, in all instances, provided with a paint reservoir enclosed within the bristles and paint conduit means communicated with the paint reservoir at one end and adapted for communication with a suitable source of paint supply at the other end. The handle portion of the paint applicator may include a hand actuated pump or may be devoid of a pump in which instance the paint conduit extending to the paint reservoir may be communicated with a supply of paint under pressure at its inlet end.
In addition to the above mentioned components, the handle portion of the paint applicator remote from the brush portion may be provided with a mounting coupling for removable securernent to one end of an elongated tubular handle. Should the paint applicator be provided with such a tubular handle, the paint conduit of the applicator may extend through the tubular handle to the aforementioned source of paint.
A main object of this invention is to provide a paint applicator including means whereby a supply of paint from a source thereof may be continuously delivered to the paint applicator thereby eliminating the necessity of a painter having to intermittently stop his work in order to replenish the supply of paint on the applicator.
A further object of this invention, in accordance with the immediately preceding object, is to provide a paint applicator including a handle portion having a paint pump mounted thereon for pumping paint from a source of paint to the appl-icating portion of the pain-t applicator whereby a painter using the paint applicator may continuously control the amount of paint being delivered to the applicator portion of the paint applicator.
Another object of this invention is to provide a combined handle-type paint pump constructed in a manner whereby it may be readily adapted for use in connection with various types of paint applicators.
A final object of this invention to be specifically enumerated herein is to provide a combined paint pump applicator and handle pump which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, long lasting .and relatively trouble-free in operation.
These together with other obje ts and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIGURE 1 is a perspective view of one form of the paint applicator of the instant invention with portions thereof being broken away to more clearly illustrate the structural details thereof:
FIGURE 2 is a fragmentary longitudinal sectional view taken substantially upon a plane passing through the handle portion of the applicator illustrated in FIGURE 1 and illustrating the structural details of the paint applicator which enable it to be removably secured to one end of an elongated tubular handle (not shown);
FIGURE *3 is .a perspective view of the mounting coupling utilized to interconnect the handle portion of the paint applicator of the instant invention and one end of an elongated handle;
FIGURE 4 is .a perspective view of a modified form of paint applicator including a paint pump in the handle portion thereof and with portions of the applicator portion thereof being broken away;
FIGURE 5 is a fragmentary longitudinal vertical sectional view taken substantially upon a plane passing through the longitudinal center line of the hand pump illustrated in FIGURE 4; and
FIGURE 6 is a vertical transverse sectional view taken substantially upon the plane indicated by section line 66 of FIGURE 5.
Referring now more specifically to the drawings, the paint applicator of the instant invention is generally referred to by the reference numeral 124 and includes a handle portion 126 .and a brush head portion 128.
The brush head portion 128 includes a plurality of brush bristles 130 similar to those provided on conventional types of brushes and disposed within the bristles 1 30 is a flexible and apertured pancake-like bladder reservoir generally referred to by the reference numeral 132. The reservoir 132 includes an inlet neck portion 1-34 and it may be observed from FIGURE 2 of the drawings that the handle portion 126 includes a longitudinal bore 136 through which the end of a flexible conduit 60 extends.
The outlet end of the flexible conduit 60 is secured to the inlet neck portion 134 in any convenient manner and it will be noted that a mounting coupling generally referred to by the reference numeral 138 is also provided for the handle portion 126 and that the mounting coupling 138 includes a cylindrical portion 140 provided with J-shaped slots 142, The end or" an elongated tubular handle (not shown) may be telescoped within the cylindrical portion 140 and be provided with laterally outwardly projecting projections releasably securable in the J-shaped slots 1'42 whereby a bayonet type connection between the cylindrical portion 140 and the associated tubular handle (not shown) may be formed. Additionally, it may be observed from FIGURE 2 of the drawings that the mounting coupling 13% is removably secured to the handle portion 1-26 by means of spring urged detent elements 144 carried by a slide 146 which is clampingly secured to mounting coupling 13 8 by means of spring arms .148 and 151 formed integrally with the cylindrical portion 140.
The end of the flexible conduit 613 remote from the inlet neck portion 134 may be adapted for communication with any suitable supply of paint. Such a supply of paint maybe under pressure so as to continuously supply paint to the reservoir 132. Additionally, a control valve (not shown) may .be disposed in the flexible conduit 60 intermediate its inlet and outlet ends for controlling the flow of paint therethrough to the reservoir 132.
With attention now directed to FIGURES 4-6 of the drawings there will be seen a modified form of brush type applicator generally referred to by the reference numeral 152. The brush-like applicator 152 also includes a pancake-like bladder reservoir 154 similar to the reservoir 132 and it will be noted that the handle portion of the applicator .152. is generally referred to by the reference numeral Patented Aug. 3, 1965 156 and comprises a hand pump. The hand pump 156 includes a pair of half handle portions 153 and 160 which are secured together by means of fasteners 161. The hand pump 155 has a reciprocal piston sleeve 162 mounted therein for reciproca-ble movement in the end of the flexible conduit 164 which corresponds to the flexible conduit 6%. A flap-type valve 166 is disposed in the inl t end of the piston sleeve 152 and opens to admit paint into the piston sleeve 162 upon movement of the piston sleeve to the left as viewed in FIGURE 5. Then, upon return of the piston sleeve 162 to the right as viewed in FIGURE 5, the flap valve .166 will close and thus force a portion of the paint disposed therein outwardly of the outlet 168 of the hand pump 156 which is in communication with the interior of the reservoir 154.
A movable actuator lever 170 is pivotally mounted between the two halves S and 168 by means of a pivot pin 172 and the piston sleeve 162 includes a laterally projecting arm 173 which is spring urged to the right as viewed in FIGURE 5 by means of a compression spring 174 disposed between the pivot pin 1'72 and the arm 173.
A pair of levers 176 are secured to the movable actuator 179 by means of pivot pin 17S and have journalled between their free ends a roller 189 by means of a pivot pin 182. The roller 18!? is disposed in rolling contacting relation with an abutment surface 184. A pair of levers 186 are each pivotally secured at one end to the pivot pin 182 and have a roller 188 rotatably supported between the opposite ends by means of a pivot pin 1%. The roller 188 is disposed in rolling contacting relation with the abutment surface 192 and in contact with the laterflly projecting arm 173 of the piston sleeve 162. Thus, upon depression of the free end of the movable actuator 170, the linkage formed by the lever 17% and 186 will be extended in order to move the arm 173 to the left as viewed in FIGURE 5. Accordingly, paint may be pumped through the flexible conduit 164 and into the reservoir 154 by actuation of the movable actuator 170.
Thus it may be seen that the hand pump 156 may be utilized to pump paint into the reservoir 154. However, it is to be noted that the applicator 152 is to be used in conjunction with a suitable supply of paint with which the inletend of the flexible conduit 164 is in communication.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
