6 Claims. (Cl. 15209) This invention relates to an improved applicator for applying and spreading paste or liquid wax on the floor or other surface which is to be wax-coated and also for polishing a coating of wax.

The principal objects of the invention are to provide an applicator which will be long wearing, which will not be adversely affected-by the wax, water or the wax solvent, which can be cleaned easily, which can be renewed in part, and which will throughout its'life spread the wax uniformly.

As herein illustrated the applicator comprises a'rigid head block, a cushion layer and a layer of fabric arranged one beneath the other in the order named with the marginal edge of the fabric layer covering the entire lower surface of the cushion layer, folded upwardly about its edges, and overlapping and being adhesively secured to thecushion layer and to the peripheral edge of the head block. The cushion layer'is preferably a sponge. The fabric layer is preferably mohair having a thick stiff pile on its outer side and the adhesive which unites the layers is in the form of an impervious barrier situated between the fabric layer and the cushion layer which is insoluble in water and the wax solvent and is not adversely affected by the wax itself. Optionally a slip cover comprised of mohair fabric may be applied to the applicator and secured thereto when the original pile surface becomes so worn as to have lost its elficacy, thereby to renew the use of the applicator and. to obtain the benefits of the unworn cushion layer without having to obtain a completely new applicator.

The invention will now be described in greater detail with reference to the accompanying drawings in which- Fig. 1 is an isometric view of an applicator embodying the invention; s

Fig. 2 is a section taken on the line 2-2 of Fig. l; Fig. 3 is an isometric view of the head block with'the cushion layer omitted;

Fig. 4 is an isometric view of a slip cover which may be used'to renew the surface of the applicator shown in Figs. 1 and 2 or applied to the head block shown in Fig. 3 without benefit of the cushion; and

Fig. 5 is an isometric view of a circular 'or disc-like applicator for use on motor driven applying and polishing machines.

Referring to the drawings the applicator as shown in Figs. 1 and 2 is comprised of a wooden head block 12, a cushion layer 14 and an applying layer 16. The head block 12 is rectangular and has a threaded opening 18 in its top side set at an angle for receiving the lower threaded end of a handle by means of which it may be pushed over the surface to which the wax is to be applied. The bottom side of the block is fiat and the cushion layer 14, which is substantially coextensive therewith, is suitably attached to the block for example with adhesive. The layer 14 is of a soft yieldingly resistant material and preferably is porous, being comprised of porous rubber such as sponge rubber or foam rubber or of one of the porous synthetics. The cushion layer ICE 2 i 14 is preferably about a quarter A) to a half /2) inch thick and its outer surface may be of somewhat smaller area than the side having contact with the'block so that and yielding as 'long as the layer '16 remains intact, that is, is not worn through or otherwise broken.

its marginal edges may be rounded olf.

The applicator layer 16 is of larger area than the cushion layer 14, covers its outer surface, its marginal edges and is turned upwardly about the edges of the block 12 so as to cover the junction between the cushion layer and the block. The applicator layer 16 is a woven fabric having a stiff pile 20 on one side, for example about oneeighth 0/8) inch in thickness and on its opposite side a layer of rubber or rubber-like material 22 which helps to anchor the pile in place and also to make the layer impervious. The layer 16 is fastened to the cushion layer 14 and the block 12 by a continuous layer of adhesive 24 which is impervious and insoluble to water and the common solvents employedin the manufacture'of'wax and also to the wax itself.

The adhesive employed herein which gives the impervious and insoluble characteristics desired is comprised of a mixture of two (2) parts of a rubber cement M244 Part land one (1) part of M244 Part 2 made by the Rubber and Asbestos Corporation of Bloomfield, New Jersey, which after being thoroughly mixed is thinned with a solvent so as to be easily spreadable. The composition is applied to the back side ofthe mohair over the rubber coating, whereupon the coated mohair is laid over the cushion layer 14 and folded upwardly so as to have contact with the edges of the block and held in this position under enough tension to slightly compress the cushion layer 14. Conveniently this is accomplished by pressing the block with the cushion layer and applicator layer facing down into a 'hollow mold and leaving it there until the adhesive cures. At room temperature curing takes'place in about twenty-four hours to make a permanent bond; The immay be'reduced by employing artificial heat. At a temperature of F. curing may be effected in fourhours, at 200 F. two hours and at 250 F. one hour.

The combined effect of the rubber layer 22 and the adhesive layer 24 is to make a continuous barrier between the inner surface of the 'applicatorlayer "16 and the cushion layer 14 which prevents penetration of water, wax, solvents, dirt and any other extraneous matter through the layer 16 into the cushion layer with the result that the cushion layer remains'perfectly elastic Consequently the elastically yielding nature of the applicator is preserved almost indefinitely unlike applicators of the conventional type wherein the wax, 'dirt'and the like enters the poresof the pad or-'cushionand eventually clogs it up so that it becomes hard and stiff, "rendering it useless after a short time in spite of careful washings after each use. The impervious and insoluble character of the adhesive also resists the caustic action of hot soapy wash water and strong solvents used in the wax so that the bond remains intact and there is no danger that the applicator layer will become detached from the block. By having the outer or applicator layer 16 overlap the block and hence the junction between the cushion layer and the block there is no danger that solvents or water can gain entrance between the block and the cushion layer.

As long as the cushion layer is maintained soft and yieldable the applicator layer 16 will also remain soft and yieldable so that wax being applied to surfaces which are not entirely flat can be spread uniformly. Moreover the yieldable nature of the cushion layer minimizes damage and wear of the applicator layer, thereby prolonging its life.

Because of the permanence of elasticity afforded by the construction described above, it is inevitable that the pile 20 will wear down to the 'basefabriceventually :and

yet the applicator will still 'have the characteristics of softness that it had in the first place. Accordingly the applicator is provided with a slip cover 26 (Fig. 4) which may be applied to renew the pile layer. .As shown in Fig. 4 the slip cover comprises a pile fabric 28 of the same kind attachedto the block, stitched along its opposite edges to a ply 30 of suitable material for example a fabric, so as to form a tubular sheath which may be slipped endwise over the head block with the pile fabric overlying the worn out applicator layer. To hold it in place the headblockis provided with fastener elements 32 and the ply 30 with corresponding mating fastening elements 34 by means of which the slip cover may be removably secured in place. A pairof openings 36 is made in the ply 30 in such a position that when the slip cover is slipped into place regardless of which side one of the openings 36 will come opposite the "threaded opening 18 so as to permit the handle to be screw into place. After each use the slip cover may be removed and washed. Thus the applicator maybe used indefinitely by replacing each worn out slip cover with a new cover.

A less desirable form of applicator and one not embodying the yieldable characteristics described above may be made by omitting the elastic layer 14 and applying the slip cover 26 directly to the block 12, the latter being shown in Fig. 3 without the sponge layer applied thereto. Of course the slip cover has to be made somewhat smaller because of the absence of the cushion layer 14.

The applicator as described above is of the block type propelled by a handle by pushing and pulling. However the characteristics of the applicator are desirable for motor-driven apparatus such as the single or double brush applicators. Accordingly it is within-the scope of the invention to make the head block circular as shown at 12a in Fig. 5. A circular cushion layer is then secured to its underside and an applying layer 16a having a pile on one side and an adhesive on the other such as described above is applied to the lower side of the cushion layer and folded upwardly about the block so as to unite the applicator layer to the sponge layer and the block.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.
