17 Claims.

This invention relates to a novel polishing pad structure of the type having a self-contained supply of polishing agent, such e. g. as a quantity of wax paste, wax powder or` other polishing medium, cleansing agent or the like; such pad structure providing a hand manipulatable polishing, medium applicator adapted to gradually exude and spread the polishing material upon a surface over which the pad is rubbed.

This invention has for an object to provide, as a complete article of manufacture ready for use, a novel wax or like containing pad structure which is of low production cost, while nevertheless being highly efficient for the intended purposes. To this end the pad structure is provided with a novel means for holding and supporti/ng its contentof wax paste or the like subject to,A gradual expression from the pad under the pressure applied thereto by the act of rubbing and moving the pad over-a surface desired to be treated. 'I'his novel wax holding and supporting means comprises preferably flexible or pliantv combined with a suitable backing or with suitable enclosing means; through which the Wax paste may be expressed from the grooves or channels when the pad is in use.

A further object of this invention is to provide a waxing or like pad structure of the general character above mentioned having either a single operative face or provided in a reversible form having a plurality of selectively usable operative faces; and the invention also contemplates the provision of wax impervious means to initially protect the operative or effective faces of the pad structure while at the same time sealing the wax content of the pad against accidental escape or deterioration of the Wax content thereof. A

Other objects of. this invention, not at this time more particularly enumerated, Will be unpad made according to the principles of this inventon; Fig. 2 is a longitudinal vert-ical sectional view of the same, takenon line 2-2 in Fig. 1; and Fig. 3 is a fragmentary transverse vertical means being provided (Cl. S51-54.7)

sectional view of a somewhat modified arrangement of said simple form of pad.

Fig. 4 is a transverse vertical sectional view` of another form of the novel waxing or like pad of the reversible type.

Fig. 5 is a transverse vertical sectional view of a, modified construction'of the Waxing or like pad embodying the principies of this invention, the same being of the non-reversible type.

Fig. 6 is a transverse vertical sectional'view of another modified form and arrangement of waxing or like pad of the reversible type.

Figs. '7 and 8 are respectively fragmentary transverse vertical sectional views of other modified forms of the waxing or like pad Within the principles of this invention.

In the novel waxing pads according to this invention, the Wax supporting means comprises cor- -rugated holder sheet or sheets II made of more -or less flexible or pliant material, which may be grease-proof or impervious to wax, although in some cases, especially when the holder sheet is enclosed in an enveloping external covering, it is immaterial Whether the same isimpervious to wax or not. In fact, in some constructions of the novel pad, it may be advantageous that the holder sheet be of perviou's material. Generally, however, it is preferable to make `the holder sheet of comparatively strong paper, such e. g. as manila, craft or the like. The corrugated holder sheet il provides on one or both faces a series of spaced grooves or channels which form pockets or holding spaces I2 into which is filled a waX` paste I3 of suitableconsistency, such as a mixture of wax and a solvent therefor.

Referring to Figs. 1 and 2, there is shown therein a simple form of the novel Waxing pad, comprising a corrugated holder sheet II having the holding spaces I2 on one side or face thereof filled with the wax paste I3. To the wax charged side or face of the holder sheet is aiXed a backing member I6, preferably of a more or less pliant character and of wax impervious material. The marginal portions I5 of the holder sheet II and the marginal portions I6 of the backing member I4 are registered in meeting relation and securedA together by a suitable glue or by any other method or means adapted to fasten and seal' these parts together, whereby the holder sheet and backing member are retained in assembled relation and the ends of the wax filled spaces I2 closed against escape of wax therethrough. The outwardly facing bottom walls of the wax lled corrugations I2 of the holder sheet, which, in

the arrangement shown in Figs. 1 and 2 are exposed to provide the workingface of the pad, are provided with a plurality of spaced wax discharge perforations or ventsv l1. Initially the outwardly presented face of the pad thus formed is covered by a removable wax impervious cover sheet I8; this cover sheet being preferably made of transparent cellulosic material such as; known to trade by the name Cellophane. The wax exposed at the perforations or vents il of the pad will be suicient to adhere and retain the cover sheet in place `until removed. vIf desired' however, a light spotting of glue of a char- -acter suihcient to hold the cover sheet against accidental displacement while not resistant to normal detachment thereof may be employed. The cover sheet it, when in place, will hermetically seal the perforations or vents il against escape of volatile constituents of the waxpaste and consequent undue hardening or other deterioration of the wax content of the pad. If

interruption of the use'of thepad occurs before entire consumption of its wax paste content, the

cover sheet it may be replaced over the working face oi the pad in closing and sealing relation the wax vents or perforations il. If desired,

. a handle loop i9 may be suitably secured to the backing member ld.

In the use of the simple form of waxing pad above described, the cover sheet l is removed prior to application of the pad to a surface to be waxed. Having removed the cover sheet it, the operative face of the pad is applied to and rubbed over. the surface desired to be treated. As the pad is pressed against the surface to be treated, the convex apical portions of the Wax holder sheet will contact said surface and will present thereto the wax vents or perforations il. The pressure exerted upon the back of the pad, together with the lateralmovements induced by the reciprocation of the pad over the surface upon which it is rubbed, by reason of the somewhat exible or pliable character of the material of which the holder sheet Il is made, Acauses both a squeezing and a lateral swaying movement or play of the wax containing corrugations of said holder sheet. Such movements effect a kneading or working of the wax content of the holding spaces i2, which assures exudation of some of the wax through the vents or perforations il for deposit upon the surface treated, over which surface the wax is spread by the wiping travel of the pad as a whole back and forthl upon said surface, It will be obvious thatthe spaced corrugations of the holder sheet it serve to segregate the wax content of the pad into individual masses upontvhich the kneading or working effects are exerted to' best advantage. By reason of the kneading or working effects, a wax paste of normally comparatively sti consistency may be employed, since said eiects quickly operate to soften the paste adjacent the vents or perorations i1 so as to assure exudation thereof without undue tendency to express a quantity of the wax in excess of that required to properly coat the surface under treatment.

The corrugations of the holder Il, which impinge upon the backing member I4 may be aflxed to the latter,- as e. g. by a suitable glue orl cement, or by 4mechanical fastening means; If

- desired, however, these corrugations which im- `pinge upon thebackin'g member may be unattached to the latter; in which case a greater scope of swaying or lateral play and consequent spaces l2.

-rugauons' will be permitted. 1f the latter arrangement is employed, the holder sheet Ill will be attached to the backing member I4 only along its marginal edge portions.

As an alternative to the simple form of waxing pad shown in Figs. 1 and 2,1 have shown a modiiied'form thereof in Fig. 3, wherein instead ofy utilizing the inwardly facing grooves or channels of the corrugated holder sheet il as the wax holding spaces or chambers, I employ the outwardly facing grooves or channels for 'this purpose, thereupon covering the same with a iacing sheet 2l) which closes over the wax lledspaces l. This facing sheet may be of textile fabric material or of any other suitable wax pervious material, or it may be of paper or the like; in the latter case it will be provided with vents or perforations 2t' aligned along and communieating with the wax iilled spaces i2.

Referring to Fig. 4, there is shown therein a waxing pad which embodies the principles ofv this invention but which further includes a construction adapted to provide a reversible form of pad; either face of which may be used at will. This form of pad comprises the corrugated holder sheet li, the'spaced grooves or channels on both sides .or faces of which are utilized as wax holding spaces or chambers I2 which are lled with the wax paste i3 or other polishing or cleansing agent. The holder sheet in this arrangement is interposed between two 'facing sheets 2l and 22, the respective marginal portions 23 and 2li of lwhich extend beyondfthe periphery of the holder sheet and are brought together and secured by glue or cement, or by any suitable mechanical fastening means, thus enveloping said holder sheet and its wax content. The facing sheets 2| and 22 may be made of textile fabric material or of any other suitable wax pervious material, or they may be made of paper or the like, in which case the same will` be provided with vents or perforations 25 aligned along and communicating with the adjacent wax lled 'l'he facing sheets 2l-22, as thus applied and joined together, constitute an enclosing envelope for the holdersheet i l. Secured to opposite margins of this. envelope are hand attachment straps 26 and 2'1, the free ends of which may be secured together by a coupling buckle 2d or other suitable ljoining means. It will be obvious that said straps 26 and 2l may be joined to form a hand attachment loop selectively entendible across one or the otherof the operative faces of the pad, according to which 4.face of the latter is to be freely presented for application to a surface to be treated. The fixed or anchored ends of the straps 26 and Zi may be interposed and secured between the meeting marginal portions 23-24 of the facing sheets by the same means which serves .to join and secure said marginal portions together, thus providing a very simple and economical method of construction. vInitially the facing sheets 2| and 22 are covered by removable Wax impervious cover sheets 29, which serve both to initially close and seal the wax vents 25, and also as a backing and vprotection against the escape of wax from that face of the pad use of which is reserved while the opposite face of the pad is in use. The cover sheet 29 on the reservedface of the pad also protects the hands of the user from contact I of this form of pad, the pad attachment straps 75 may be reversed, the cover sheet 29 on the .re-

' it too is discharged of its wax content. In the A thereof opposed in register or alignment.

use of this form of the pad, the pressure and lateral play effective upon the corrugations of the holdersheet will also produce the wax kneading or working effects calculated to assure the desired Agradual exudation of the wax content thereof.

In Fig. I have shown a pad construction of vnon-reversible form, but having an arrangement of holder sheet means calculated to provide a larger Wax content capacity, than does the simple arrangement of holder sheet means shown in Figs. l and 2. In the construction shown in Fig. 5, two corrugated holder sheets II are arranged in superposed relation with interior grooves or channels 'thereof opposed in register or alignment to thereby provide double capacity wax holding spaces or chambers I2 in which the wax paste I 3 is lodged. The margins 3B of the holder sheets Il are brought together in meeting relation and secured, as by glue or cement, or by other fastening means. The holder sheet structure thus provided is backed on one side by a wax impervious backing member 3l suitably secured thereto. If desired, a hand attachment loop 32 may be secured to and across said backing member. The convex apical portions of the corrugations exposed along the opposite face of the holder sheet arrangement are provided with a plurality of spaced vents or perforations Il through which the wax may be discharged when the pad is in use. The pad thus formed may be provided, in secured and covering relation to its working face, with a facing sheet 33 of textile fabric or other wax pervious material. of such facing sheet vis optional. In Fig. 6 I have shown another form of th novel waxing pad adapted to provide a large wax content capacity; as shown the pad is of the reversible type. In this construction, a plurality of holder sheets II are arranged in superposed relation with interior grooves or channels All the grooves or channels on both faces of each so arranged holder sheet II are constituted 'wax holding spaces or chambers I2 and are filled with the wax paste I3. 'Ihe holder sheet arrangement is enclosed between facing sheets 34 and 35, the marginal portions of which are extended beyond said holder sheet arrangement and are brought together and secured one to the other, thus forming an enclosing envelope around said holder sheet arrangement. If desired reversible hand loop straps 36 and 31 are secured to opposite margins of the pad, the free ends of said straps being detachably coupled together by a suitable fastener 38. The side walls of the corrugations of the respective holder sheets are provided with openings or perforations 39 whereby communication is established between the inner and cuter wax holding spaces or chambers I2, so that when the pad is used, and under` pressure-and kneading or working effects similar to those already described, the wax will be gradually fed from inner to outer spaces or chambers as consumption from the outer spaces or chambers occurs by reason of discharge `of Wax therefrom when the pad is in use. In this modified pad structure, instead of employing wax impervious sheet material for thecorrugated holder means and The use providing therein the intercommunicating openings or perforations- 39, said corrugated holder means may be made vof wax pervious material, such e.-g. as muslin or a more or less stffened porous textile fabric. The facing sheets 34 and 35 are provided with a plurality of wax discharging vents or perforations 40 which comv municate with the respective outer wax filled spaces or chambers of the holder sheets. Each facing sheet 34 and 35 is initially covered over with a detachable Wax impervious cover sheet klil which closes and seals the underlying wax discharge vents or vperforations 40. It will be obvious that while one .working face of this type of pad is in use the other or second face thereof is in reserve, but may be used when desired by reversing the pad. Although but two holder sheets have been' shown relative to the last described form of the pad, it will be apparent that more than two holder sheets may be superimposed to form the wax supporting and carrying means the'eof.

' Other variations in the form and arrangement of the pads, but including the basic element of a corrugated wax holder sheet structure, are possible. Illustrative of some of such further variations, I have shown in Figs. 7 and 8 additional modified forms of reversible pad types.' In Fig.

Over the desired, a wax pervious outer facing sheet of textile fabric may be secured over each facing sheet 43. In Fig. 8 the pad structure comprises an intermediate or partition vsheet 46 of wax impervious material. Upon opposite sides of said partition sheet 46 are superposed corrugated holder sheets II, the inwardly facing grooves or channels I2 to contain the wax paste I3. Provided in the outwardly presented convex apical covered with a layer 48 of wax pervious textile.

If desired,

fabric of any suitable character. this fabric layer or cover may be made of terry cloth or other pile napped material. Removable cover sheets of wax impervious material, such e. g. as Wax paper, glassine paper, Cellophane or the like may be employed for the purposes-hereinbefore referred to. It will be obvious that, in the use of pads of the type shown in Figs. 7 and 8, ythe Wax impervious intermediate'or partition sheets serve to back the particular Wax holder sheet which is applied for the discharge of its wax content upon a surface to be treated; the same operating to transfer pressure in use to the wax content so as to discharge the same, while corrugations are subject to the same lateral play or movement effective to produce the desired kneading or working of the wax content in aid of operative exudation thereof.

It will be obvious that many other variations and modifications of the novel pad structure, other than those already hereinabove referred .channels of which provide holding chambers,
