[57] ABSTRACT An applicator for applying paints or adhesives to a surface in various width stripes includes a guide member and a dispensing element. Different width stripes are obtained by positioning the external surfaces of the dispensing element in predetermined spatial relationships relative to the edges of the guide member.

6 Claims, 3 Drawing Figures cab/9770s PATENTEU MR 1 9 I924 sum 10F 2 PAINT AND ADHESIVE APPLICATOR BACKGROUND OF THE INVENTION This invention relates to adhesive and paint applicators and, more particularly, to applicators for dispensing adhesives and paints in various width stripes.

In numerous instances, it is both desirable and necessary to apply an adhesive or a paint to a surface in various width stripes. Historically, such stripes were obtained by the laborious technique of employing a small hand brush. Indeed, use of a hand brush consumes an inordinate amount of time. In addition to being inefficient, use of a hand brush also yields nonuniform stripes. More often than not, adhesives applied via the hand-brush technique were not properly distributed and, hence, poor adhesion resulted.

Numerous devices have been proposed in an attempt at overcoming the obvious disadvantages of the early hand brush application technique. For example, devices including various felt wheel arrangements have been employed to apply adhesives and paints in stripes on surfaces. For the most part, the prior wheel-type applicators are clumsy and awkward, requiring wheel size changes in order to obtain different width stripes.

Still other known devices utilize a variety of nozzle and similar arrangements for applying adhesives or paints to surfaces. Like the wheel devices, a change in the nozzle is required to obtain a different width stripe.

In general, the prior known adhesive and paint applicators lack symmetry. That is to say, the adhesive or paint could only be applied to a surface when holding the prior devices in a single position relative to the surface on which the stripe was being applied. Such arrangements become awkward when applying adhesives or paints to surfaces having numerous bends or turns, thereby requiring turning of the applicator in order to obtain a desired stripe.

SUMMARY OF THE INVENTION These and other problems are resolved in accordance with the inventive principles to be described herein for applying adhesives or paints to a surface in various width stripes. An applicator, in accordance with the invention, includes a guidemember having a predetermined geometric shape and a dispensing element also having a predetermined geometric shape advantageously mounted upon the guide member. Various width stripes of an adhesive, paint or other liquid .being dispensed are obtained, in accordance with the invention, by selectively positioning the external surface of the dispensing element in predetermined spatial relationships with the edges of the guide member.

In one embodiment of the invention, a guide member and a dispensing element both having substantially square external shapes are employed to obtain different width stripes. The surfaces of the guide member are arranged advantageously to support the dispensing element so that a desired flow of adhesive or paint is'realized. Accordingly, the dispensing element, which may be a felt wick or the like, is supportedly mounted in substantially the center of the guide member protruding from the lower surface by a predetermined distance. A container for holding a supply of the adhesive or paint being dispensed is also mounted on the guide member and is arranged so that the adhesive or paint is readily supplied to the dispensing element. The container is also advantageously arranged to serve as a handle for the applicator.

Various width stripes are obtained, in accordance with the invention, by positioning the external edges of the dispensing element in predetermined spatial relationships with the edges of the guide member. For example, in this embodiment of the invention, a first width stripe is obtained by positioning the edges of the wick dispensing element so that they are substantially parallel to'the edges of the guide member. A second larger width stripe is obtained, in accordance with the invention, by rotating the wick dispensing element so that its edges are positioned at at least a predetermined angle relative to the edges of the guide member.

A feature of the invention, therefore, is that different width stripes are obtained while maintaining symmetry of the applicator.

BRIEF DESCRIPTION OF THE DRAWING These and other objects and advantages of the invention will be more fully understood from the following detailed description of an illustrative embodiment thereof taken in connection with the appended drawings in which:

FIG. l is an exploded perspective view of an applicator illustrating the principles of the invention;

FIG. 2 is a sectional view further showing details of the applicator of FIG. 11; and

FIG. 3 is a break-away view of the guide member of FIG. 1 illustrating the relationship between the wick and guide member.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 illustrates an applicator assembly generally indicated as H which, in accordance with the invention, dispenses paints or adhesives in various desired width stripes. FIG. 2 is a sectional view showing an assembled version of applicator 10.

Accordingly, applicator 10 includes guide member 11 which, in this example, not to be construed as limiting the scope of the invention, is a template having a generally square shape. The edges of guide member 11 are rounded to allow for smooth movement along the boundary of various surfaces to which paint or adhesive stripes are being applied. Circular passage 12 is positioned substantially in the center of guide member 11 and is advantageously arranged to accommodate mounting of adapter assembly 20.

Base ring is advantageously mounted on guide member ll] by screws (not shown) passed through holes 14. Ring 15 has a threaded passage ll6 for accommodating ball plunger assembly 17. Ball plunger assembly f7 may be anyone of the numerous types known in the art. Preferably, a Jergens ball plunger is employed in this embodiment of the invention.

External and interior dimensions of ring 15 are arranged to accommodate adapter assembly 20. Assembly 20 includes adapter 21, collet 22, collar 23, and dispensing element 24. Dispensing element 24 is held by collet 22. When assembled element 24 is arranged to protrude from both the upper and lower surfaces of collet 22 by predetermined distances. In this example, dispensing element 24 is a felt wick having a substantially square cross section.

Adapter 23 is substantially cylindrical in shape having a stepped exterior surface for coacting advantageously with base ring 15. The lower portion of the external surface of adapter 21 is threaded to accept collar 23. Adapter 21 also has a lower interior passage which is tapered and dimensioned to accept collet 22. Collct 22 is arranged to hold dispensing element 24. When assembled, collet 22 and dispensing element 24, are inserted into the tapered lower passage of adapter 21 and held in place by collar 23. Because of the taper, tightening of collar 23 causes collet 22 to close about dispensing element 24, thereby securing element 24 in place, as shown in FIG. 2.

The central portion of the external surface of adapter 21 has a plurality of hemispherical indentures namely, indents 25 and 26, which eoact with ball plunger 17 for positioning adapter 21 and, hence, dispensing element 24 in predetermined spatial relationships, in accordance with the invention, with the external edges of guide member 11. In this example, adapter 21 (FIG. 1) has been rotated by 90 relative to ball plunger 17 for purposes of illustration. The external diameter of the central portion of adapter 21 is substantially equal to the interior diameter of ring 15.

The upper portion of the external surface of adapter 21 has a predetermined diameter so that adapter 21 seats on ring 15, as shown in FIG. 2.

Adapter 21 has an upper threaded passage dimensioned to accommodate container 30. The upper and lower passages of adapter 21 are contiguous thereby allowing fluid communication between container 30 and wick 24. Container 30 may be constructed of any material capable of holding the paints or adhesives to be dispensed. It is preferred, however, that a glass container be employed having sufficient thickness so that container 30 may be used as a handle for applicator 10.

When assembled, applicator takes the form shown in FIG. 2. Note that dispensing element 24, which in this example is a felt wick, is arranged to protrude below the lower edge of guide member 11. The paint, adhesive or other liquid to be dispensed flows from container 30 to element 24. The surfaces of guide member 11 are arranged so that only the lower surface of the felt wick, i.e., element 24, engages surface 40 (FIG. 2) when the edge of guide member 11 engages boundary 50 of surface 40.

A first width stripe of a paint or an adhesive is obtained, in this example, by arranging adapter 21 so that one of the indents, for example, indent 25 engages ball plunger 17 when the edges of element 24 are in substantially parallel alignment with the edges of guide member 11. Then, a second width stripe is obtained, in accordance with the invention, by rotating adapter 21 by a predetermined angular displacement. In this example, adapter 21 and, hence, element 24 is rotated by 45 (FIG. 3). Again, ball plunger 17 engages indent 26 to hold adapter assembly in place.

FIG. 3 illustrates the various width stripes obtained, in accordance with the invention, by rotating element 24 relative to the edges of guide memeber 11. The stripe obtained when the edges of element 24 are substantially parallel to the edges of guide member 11 is shown by the solid lines, while the stripe obtained when element 24 is rotated by 45 relative to the edges of guide member 11 is shown in dashed outline.

As can be readily seen from FIG. 3, stripes having different widths are obtained while maintaining symmetry of applicator 10. This symmetry greatly simplifies the application of paints or adhesives in different width stripes onto a surface because the applicator may be freely rotated relative to a reference position, for example, a horizontal plane.

In one example from practice, applicator 10 is advantageously employed in the installation of the foil strips used in burgular alarm systems. In installing the foil strip in such systems, a first width stripe of a varnish adhesive is used to secure the foil to a glass surface, for example, a windown, a door or the like. Then, a second wider stripe of varnish is used to seal the foil to the window. As stated above, various width stripes are obtained, in accordance with the invention, by positioning dispensing element 24 (FIG. 3) in predetermined spatial relationships with the edges of guide member 11.

The above-described arrangements are, of course, merely illustrative of the application of the principles of the invention. Numerous other arrangements may be devised by those skilled in the art without departing from the spirit and scope of the invention.
