INVENTOR. LEE 5. CHADWICK II BV K Z 64:
A T TORNEV United States Patent 3,134,130 PRESSURE FED LIQUID APPLICATOR Lee S. Chadwick H, St. Albans, Vt., assignor to Union Carbide Corporation, a corporation of New York Filed June 22, 1961, Ser. No. 118,997 6 Claims. ((31. 552) This invention relates to an applicator for liquids and refers more particularly to an applicator of the type wherein a liquid is supplied to a liquid applying surface from an external liquid reservoir by pressure means. For reasons of convenience, the discussion of the invention will be particularly directed to paint applicators.
The use of a roller instead of a brush to apply paint to a surface has become a widespread practice. The well known roller and pan method of applying paint wherein the roller is dipped in a pan or tray of paint is commonly practiced, but it is inconvenient with respect to the time consumed in pan rolling to obtain the desired distribution of paint on the roller and the relative undesirability of operating from an open, spillable, pan of aint. p The prior art is replete with methods for applying paint to the surface of a roller. For example, hollow rollers are designed to be filled internally by hand and then sealed for use. The paint is deposited on the surface of the roller by absorption through the material covering the roller surface. Unfortunately, these rollers are excessively heavy due to the internal paint reservoir which must be carried, and also, they must be frequently refilled.
Other rollers call for a distribution tube extending across the surface of the roller which permits the paint to be deposited directly on the external surface of the roller. A roller disclosed in U.S. Patent 2,955,310 is provided with a manifold with spaced openings in pressure contact with the roller which permits paint to be applied directly to the surface of the roller, with a minimum of splattering. A particular problem encountered with this type of roller is the tendency for the paint to be applied in streaks rather than uniformly on the surface to be painted. Moreover, for one reason or another, all of the roller systems of the prior art have been found to possess some inherent disadvantages.
The principal object of the invention is to provide a pressure fed liquid applicator with improved means for depositing and distributing the liquid on the surface of the applicator.
Another object of this invention is to provide a painting system wherein the paint is completely confined until it is delivered to an applicator.
Still another object of the invention is to provide a completely portable leak-proof and spill-proof painting system.
The above objects are accomplished by the applicator of the invention which comprises a paint pervious belt which rotates about a paint impervious core and a paint feeder tube. The paint feeder tube is provided with aperture means which allow the paint to be deposited on the inner surface of said paint pervious belt and thereby ultimately on the outer surface of said belt. A completely portable painting system is provided by connecting the above described applicator to a portable sealed paint container which is in communication with a portable pressure source.
The particular liquid pervious material to be employed as the belt depends, of course, in each instance, on the particular liquid or paint to be applied. Among suitable materials are porous flexible plastic foams, porous natural and synthetic rubber, porous paper, etc. An open-pore polyurethane belt approximately one-quarter inch thick has been found to serve as an excellent paint pervious belt.
3,134,130 Patented May 26, 1964 The invention will be more readily understood by reference to the accompanying drawing, wherein:
FIG. 1 is a front elevational view, partially in section, which illustrates an applicator embodying the invention in conjunction with a reservoir of paint and pressure means for delivering said paint to said applicator;
'FIG. 2 is a view taken along the line 2--2 of FIG. 1;
FIG. 3 is a horizontal sectional view along the line 33 of FIG. 2, showing a feeder tube having a slot of increasing width; and
'FIG. 4 is a vertical sectional view of a feeder tube having a passageway diagonal to the axis of the feeder tube and showing a slot of varying depth.
Referring now to the drawing, a completely portable painting system is shown which comprises a pressure source 10, in communication with a closed paint container 12, and an applicator 14 as its basic components. Any pressure source 10 may be employed, a convenient source being a closed container which contains a liquefied gas. A shut-off valve 16 is provided between the pressure source 10 and the paint container I12 or if desired a conventional pressure regulator (not shown) may be used. A flexible hose 18 connects the paint container 12 to a handle 20 provided with a conduit 21, and to which the paint applicator 14 is attached. A control valve 22 is provided in the handle member 20. A conduit member 24 connects the handle 20 to a hollow end fitting 26 provided on the applicator 14. A paint impervious core 28 is mounted in the yoke 29 of the paint applicator 14-. Preferably, this core 28 is mounted so that it is free to rotate within the yoke 29. Fixedly mounted in the yoke 29 of the applicator 14 and in communication with the hollow end fitting 26, is a feeder tube 30. The passageway 31 in the feeder tube 30 is in communication with the surface 'of the feeder tube 30 by means of a longitudinal slot 36 which permits the paint from the feeder tube 30 to be deposited on the inside of a paint pervious belt 32 which is mounted on the paint impervious core 28 and the feeder tube 30. The paint pervious belt 62 will rotate about the paint impervious core 28 and the feeder tube 30 as the applicator 14 is moved over the surface to be painted. A bracket 34 seals the far end of the paint passage of the feeder tube 30.
In order to insure a more uniform deposit of paint across the entire inner surface of belt 32, the width of the slot 36 which connects the passageway 31 with the surface of the feeder tube 30 should be narrowest at the end which first receives the paint under the highest pres sure, i.e., at :end fitting 26, and it should become wider the further across the feeder tube 30 it extends to compensate for the pressure drop which is encountered as shown in FIG. 3. Alternatively, the width of the slot 36 may be kept constant and instead the passageway 31 may be provided diagonally to the axis of the feeder tube 30' as shown in FIG. 4. The 'depth of the slot 86' should be greatest at the end which first receives the paint and least at the far end of the feeder tube 30". The greatest slot depth, results in higher fluid friction, and thus compens-ates for the higher pressure at the feed end of the passageway 31.
Operation of the illustrated system is as follows: When the valve 16 is opened, the paint in the container 12 is pressurized due to the pressure source 10, and the paint will flow through the flexible hose 18 into the conduit 21 provided in the applicator handle 20. When the valve 22 is opened, the paint will flow through the conduit member 24 into the end fitting 26 and subsequently into the passageway 31 of the feeder tube 30 from whence it passes to the paint pervious belt 32 by means of the longitudinal slot 36. As the belt '32 is caused to rotate about the paint impervious core 28 and the feeder tube 30, the paint is constantly deposited on the inner surface of the 3 belt 32 and it permeates the belt 32 through to the external surface as the line of deposit on the belt approaches the impervious core 28, and the paint will be transferred to the desired surface as the applicator is rolled over it.
The paint pervious belt performs a two-fold purpose. First it aids in the even distribution of paint across the paint applicator, and secondly, it serves as a paint reservoir, thereby preventing drippage.
It will of course be appreciated that the applicator device of the invention is also well suited to the application of other liquid coatings such as, for example, floor wax, white Wash and varnish.
