WAX APPLICATOR AND METHOD OF MAKING THE SAME Filed Nov. 27, 1934.
LACQUER CELLULOSE INVENTOR JOHN S TROOP ATTORNEY '20 for these purposes.
disintegrated by the hydrocarbon solvent in the Patented Feb. 23, 1937 WAX APPLICATOR AND METHOD OF MAKING THE SAME John Stroop, New York, N. Y., assignor to Pad-Y- Wax Company, Inc., a corporation of New York Application November 27,1934, Serial No. 754,951 '13 Claims. Rel. 91-625) The present invention relates to wax applicators and methods of making the same.
The present invention contemplates a form of wax applicator. which is a complete article of manufacture provided with a quantity of wax substance and solvent held in a porous reservoiring structure suitable for direct application to a surface to be waxed and of a nature to gradually give up the wax as it is rubbed on the surface, and yet require no extraneous means (as a cover) to 1191a it together. v
Most porous structures, such as cloth, felt, and the like, which require no covering means to hold them intact are unsatisfactory for the purposes as they have a very limited power to absorb wax, and retain a very large proportion of what they do absorb. The more common structures of high degree of porosity, such as rubber sponge or natural sponge are not suited The rubber sponge is quickly wax and by the wax itself so that this material cannot be employed. Natural spongejbesides being too expensive is notavailable in satisfactory qu ntitiesand sizes and with the uniform porosity required of a manufactured article. The preferred reservoiring material is an artificial sponge of nitrated cellulose. Y
, This sponge is artificially produced by nitrating and processing a base of cellulose stock in such a manner that a sequence of interconnected cells are created in a structure which functionally has every attribute of the natural sponge. This process is known and forms no part of the present invention. This artificial sponge forms a highly compressible structure of flexible skeleton form having interconnected voids and has the advantage of possible production in any shap or size suitable to wax applicators and in addition to this can be produced with cell or pore characteristics exactly designed to serve as the efilcient reservoir for wax. The cellulose character of this sponge is unaffectedby waxes or the customary hydrocarbon solvents of wax compounds. Hence 5 ficial sponge in contact.
' The applicators may be produced in any size determined only by the amount of wax to be reservoired. The applicator may be of small size suitable for waxing shoes or furniture or for automobiles or maybe larger to reservoir sufficient wax for floor waxing. A further object of the present invention is to providethe sponge with'an impervious back. This may, for example, be in the form of a sheet a stable article may be made with wax and artiand passed under a scraper l2 which holds the of lacquered fabric secured to the sponge by adhesive or bysewing, or may comprise a layer or coating of cellulose lacquer. Where a handle is desired, the handle may be secured in place by lacquer which acts as an adhesive, or by sewing.
The accompanying drawing shows, for purposes of illustrating the present invention several embodiments in which the invention may take form together with the method of making the pads, it
being understood that the drawing is illustrative of the invention rather than limiting the same.
In this drawing:
Fig. l is a diagrammatic view illustrating a portion of the process of manufacture;
Fig. 2 is a similar view illustrating, a further portion of the process;
Fig. 3 illustrates the cutting of the waxing pads into units; V
Fig. 4 is a perspective view of a maxing pad showing the manner of use; and j Figs. 5 to 8 inclusive are sectional views through pads of various forms of construction.
The artificial cellulose nitrate sponge used in making these pads has a high degree of porosity. The openings are preferably as large as possible and yet retain the wax in place. Too large holes permit large masses of wax without anything to hold them in place, and are therefore to be avoided. Too small pores hold the wax back and hinder its flow when the .pad is rubbed over a surface. A sponge with the maximum size of opening of about inch is preferred.
The sponge is cut or formed to the right thickness (approximately inch for a hand pad).
For ease in processing, a large sheet or layer of sponge is employed suflicient for the manufac-- ture of a number of pads.
The cellulose sponge in its natural state is stiff and harsh and-not suitable for rubbing on a surface to be waxed- This harshness is not present when the sponge is wet. Water has a softening physical effect on the sponge, but it is not permanent. ,On evaporation of the water the hard state is restored. The treatment of the sponge to receive the wax involves twostrips, the providing of an impervious back and the softening ,of the sponge. Either step may be performed first. I
To render the back of the sponge sheet im'- pervious to'wax and wax solvents, the sponge may be coated with a lacquer as shown in Figure 1. The sponge layer is indicated at. l0, and nitro cellulose lacquer is flowed onto it as indicated at H. The sponge is moved to the right While the lacquer is still wet, handle strips having loops H which project up so as to stay out of the lacquer. The lacquer dries very quickly and seals all the pores on that side of the sponge as well as secures the handles in place.
The softening may be accomplished and permanently retained if the water is mixed with a suitable hygroscopic agent to prevent evaporation. These agents may include a number of organic materials which are compatible with the wax and sponge. Glycerine is the preferred agent for this purpose. The sponge sheet is passed under a spout l9 which applies a solution of glycerine in water. From 30% to of glyceririe may be used. The wet sponge is then squeezed to remove as much of the glycerine and water as possible. This may be done We wringer 20. The glycerine retained will not evaporate and will insure that the water content is always present. If desired, the glyoerine and water may be applied and wrung out before the lacquering step.
The softened sponge is then passed under filler spouts 2| where the wax and wax solvent, heated slightly to melt them, is allowed to fiow onto the sponge. A sufiicient quantity is emplayed to fill all the pores. Any excess may be removed by a scraper 22. The wax solidifies. and the large sheet is then cut, as indicated at 23 and 24 of Figure 3, to form square or rectangular pads, each having a uniform charge of wax, a flexible impervious backing and a handle. Instead of hydrocarbon-type of wax, one may use an emulsion type of wax. The pad is shown in Figures 4 and 5.
The pad produced as described is ready for use. The user can-pass the fingers through the strap as indicated in Figure 4 and easily rub the pad over a surface so as'to leave a film of wax. The surface of the pad is soft and pliable and'produces a. very satisfactory feel" as the pad is used. As the pad is used the wax keeps worldng out to the pad surface so as to be ready to be transferred to the surface of the article being waxed. The pad is pliable so that a sub.- stantially kneading action takes place. The en tire supply of wax may therefore be used. Owing to the impervious layer at the back,the hand does not become soiled.
These applicators are packaged in cellophane I envelopes which protect the wax from deteriorative evaporation. These envelopes are superior to cans or bottles in ease of access and are resealable in such a manner that no loss of wax occurs.
Figure 6 shows a pad similar to that of Figure 4, except that the handle strap 25 is formed to receive all four fingers. It is secured in the lacquer backing while still wet.
Figure 7 shows'a pad in which a layer 2} of fabric, preferably lacquer coated (or oilcloth) is secured to the sponge'body. byadhesive lacquer 21. The handle 28 is secured by adhesive.
