13 Claims. (Cl. 15-131) This invention relates to polishing devices and is more particularly concerned with improvements in a polishing device whichis particularly designed for bufiing or shining shoes.
It is a general object of. the invention to provide an improved polishing device in the form of an elongate generally rectangular strip or sheet of relatively fiexible material having a supply of a polishing. substance on one face or surface thereof for application to the surface of the shoe or other object to be polished, and having an opposite face or surface suitable for bufling or polishing the surface of the object when .the ends of the device are gripped in the hands of the user, the device being initially provided in a neat and compact package which makes it convenient for storage and use by travelers, hotel guests, or others who desire an inexpensive device which may be kept readily available for this purpose.
It is a more specific objectof the invention to provide a shoe polishing device which is formed preferably of non-fabric materialscut from a web or sheet so-as to provide an elongate strip with a polishing substance provided on one. face thereof and with the opposite face being available .for bufiing the shoe with or without the application of the polishing substance to the surface.
It is another objectof the invention to'provi'de a shoe polishing device. orkitwhich comprises an elongate strip of a laminated web or. sheet having: a supply of a polishingsubstancecarried onone face thereof, which web or sheet isv formedby binding an absorbent paper to oppositefaces-of acarrier web or sheet'of material-came ble of preventingthemigration of the polishing substance from one. face to the other.
It is. a. further object of the invention to'provide'a readily disposable non-fabric shoe polishing device which comprises-.a pair offibrous sheetsof generallyrectangular,. elongateform bound together bya flexible plastic film andhaving on onesface thereof a series of spaced spotsor stripes of apolishing. substance, with the composite strip being. folded onspaced foldlines Which'are located between the spots of polishing substance so as to. bringthe spots ofpolishingsubstance into face-toface contact. in the-folded condition in which thedevice is storediorspackaged a I It isranother. object of the invention to provide a shoe polishing device of cloth-like form which is fabricated by. bonding. elongate. strips of paper or similar fibrous sheet or web material to opposite faces of a similar strip of thermoplastic film 'and'applying a series-of transversely extending. and longitudinally spaced stripes of polishing-- wax to. one face thereof, thecomposite strip or cloth being then folded on transverse fold lines which are longitudinally. spacedand located between the stripes of polishingwaxsothat the stripes of wax will bein faceto-face contact. a
.It is still another object of the invention to provide a shoe polishing device of the character referred to where inthesheetrnaterials employed are capable of stretching Patented N ov.. .29, 1 9.60.
in the direction longitudinally of the composite strip so that when the device is gripped at opposite ends by the user and applied to the shoe surface for the polishing operation, it will stretch over the surface of the shoe and conform to the contour thereof.
It is a further object of the invention toprovide a shoe polishing device of the character described which is formed from a laminated'material comprising a pair of strips or webs of relatively soft absorbent paper which is creped or otherwisetreated to render it somewhat stretchable and bound by heat and pressure to opposite faces of a flexible and stretchable plastic film whereby the device, when grasped at opposite ends and pulled back and forth across the surface of the shoe, will conform to the contour of the surfacethereof during the polishing opera tion.
It isanother object of the invention to provide a method of fabricating a polishing device wherein continuous webs of absorbent non-fabric sheet material, for example, paper, are broughttogether on opposite sides of a thermoplastic film and bound thereto by heat and pressure, apolishing wax is applied in continuous longitudinally extending transversely spaced stripes to one surface of the composite web, the web is folded onlongitudinal transversely spaced fold lines which are located between the stripes of polishing wax into compacted relation, with the stripes of polishing wax in face-to-face contact and with marginal edge portions being free of the wax, the compacted material is cut into sections, each forming an accordion folded unit, of elongate rectangular form when opened out, which sections are thereafter enclosed in wrappers or envelopes formed from sheets or webs of substantially impervious wrapping material and hermetically sealed therein, thereby providing an inexpensive polishing device which can be stored' for a substantial period of time without hardening of the polishing wax and which may be readily disposed of after one or several polishing operations.
These and other objects and advantages of the invention will be apparent from a-consideration of the polishing device and the method of fabricating the same which is shown by way of illustration in the accompanying drawings wherein:
Figure 1 is, a perspective view of a shoe polishing device enclosed in a protective wrapper or envelope in which the device is adapted to be marketed;
Figure 2 is a plan view of the shoe polishing device in opened. out, ready for use condition, with the polish applying face uppermost;
Figure 3 is a perspective view ofthe polishing device in partially unfolded condition;
Figure 4 is a partial side edge view of the polishing device in the folded condition, to an enlarged-scale, andwith the thickness of the material being exaggerated;
Figure 5 is a plan view of one endof the polishing device, to anenlarged'scale, and with portions broken away; V
Figure 6 is a fragmentary plan view of a modified form of the polishing device;
Figure 7 is a schematic perspective view illustrating. a method of fabricating the device of Figure 1; and
Figure 8 is a schematic plan view illustrating the methodof Figure 7.
Referring to Figures 1 to 5 of the drawings, there is illustrated a form of polishing device which embodies the principal features of the invention and which is particularly adapted for supplying the needs of travelers and others who desire a readily available and inexpen sive device having the form or shape of the fabric cloth strips commonly used for polishing shoes but which will have incorporated therein a supply of polishing wax sufii cient for one or two applications and a buffing surface for polishing the shoe after the application of wax and which may be readily disposed of after being used once or several times at the most.
The polishing device 10, as illustrated, comprises an elongate strip of material having the generally rectangular form in which Woven or knitted fabric strips or cloths provided for shoe polishing purposes have generally been supplied. The device has flexibility and bufiing or polishing characteristics comparable to a cloth strip supplied for the same purpose and for convenience in description it may be referred to as a polishing cloth. However, it will be understood that when the device is designated as a cloth, the intended use of the device is referred to and not the material from which it is formed.
As shown in Figures 4 and 5, the polishing device or cloth 10 comprises outer or facing strips 11 and 12 of flexible paper or similar sheet material and an inner carrier strip 13, which is preferably of a continuous thermoplastic film, and to the opposite faces of which the outer strips 11 and 12 are adhered. One of the facing strips which may be conveniently referred to as the inner strip 11 is provided on its exposed surface with a series of longitudinally spaced transversely extending stripes or spots of a paste wax or other polishing substance. The stripes of polishing wax 14 are applied intermediate the ends of the device and gripping spaces 15 and 16 are provided at the ends of the device, the latter being free of the polishing substance and enabling the user to firmly grip the ends of the device in his two hands without contacting the polishing substance when the device is opened out and employed in the polish applying and butfing operations. The device is initially formed into a neat and compact unit by dividing it into sections of equal length which are folded in accordion fashion on the transversely extending fold lines 17, with the fold lines 17 being located between stripes 14 of the polishing substance so that when the device is folded the stripes or areas of the polishing substance are in face-toface contact which results in a minimum of evaporation of the solvent or plasticizer.
To further prevent evaporation of the polish solvent or plasticizer, the device 10 in its folded and compact condition, is wrapped or packaged in an envelope-like container 18 which preferably comprises superimposed sheets 19 of a moisture vapor proof material which are hermetically sealed at the peripheral margins 20 to enclose the folded device or cloth 10.
The exterior sheets 11 and 12 of the polishing device 10 are preferably formed of a relatively thin, flexible, fibrous, sheet material, such as paper, of a type which has substantial moisture absorbing characteristics, for example, paper toweling and creped paper. Preferably, the paper is of the type in which the fibers are arranged with the longitudinal axes extending in one direction which results in the paper having substantial stretch in the direction transversely of the long axis of the fibers with substantially less stretch in the direction of the long axis of the fibers. In another form of the device the paper may be embossed or creped in both directions in order to provide the desired stretched characteristics. A further material which has been found satisfactory for the exterior sheets is available commercially under the name Miracloth which is understood to comprise cellulose fibers treated or sized with a material which is insoluble in water when dry, so that it may be washed, and to which dust and dirt tend to adhere, the fibers being arranged to extend in the same general direction so that the material, when formed into relatively thin sheets, has substantially greater stretch in the direction transversely of the long axis of the fibers than in the direction of the long axis thereof. This material has sufiicient strength for use in forming the device 10 while at the same time it is capable of stretching a substantial amount in the direction transversely of the grain without rupturing so that it conforms to the surface of the object being polished when used for the bufiing operation.
The inner ply or binder sheet 13 is preferably formed from a relatively thin flexible thermoplastic such as polyethylene or vinyl sheeting Pliofilm, or the like, which is impervious to water and which serves as a barrier against the migration of the polishing substance which is carried on the one outer ply or sheet 11. The plastic film is preferably capable of stretching sufficiently to cooperate with the polish applying and buffing exterior sheets 11 and 12 in conforming to the contour of the surface which is being polished and has sufficient strength to reinforce the exterior sheets and resist tearing when in use.
The polishing substance which is preferably applied in the form of stripes 14 to the exterior surface of the outer ply or sheet 11 may be a paste-type shoe polish formed from carnauba, montan, cerisin or other wax with a suitable hydrocarbon or alcohol solvent. A sufficient amount is applied on the stripes or spots 14 to polish a pair of shoes. The spaced stripes or spots 14 of the polishing substance are arranged on the surface of the outer sheet 11 so that the device 10 may be folded as shown in Figures 2 and 3 to bring each of the stripes or spots 14 into face-to-face contact with another stripe or spot 14 and reduce to a minimum the exposed surface of the polish thereby minimizing the degree of evaporation of the solvent between the time of the application of the polish and the use of the device. The particular shape or form of the stripes or spots 14 is a matter largely of choice, it being possible to apply the polish in a decorative pattern or in order to provide information, such as, for example, the trade name under which the device may be marketed, It is desirable to have the polish applied in a pattern which is arranged so that at least substantial portions of the coated areas will be in face-to-face engagement when the device is folded into package form. This is desirable to keep the rate of evaporation of the solvent to a minimum and thus increase the period over which the device may be stored without hardening of the polish before it is used.
A modification of the device is shown in Figure 6 in which the one face of the device 21 is provided with stripes or areas 22 of the polishing substance which are bordered or enclosed by a relatively narrow line or band 23 of paraffin wax, the latter providing a readily separable seal around each stripe 22 of polish when the device 21 is folded as illustrated in Figure 3 with the polish stripes 22 in face contacting relation. This border or band of parafiin, when pressed into engagement with a like band of paraffin, provides a seal to aid in retarding the evaporation of the solvent in the polish in the stripes or areas 22 and increases the effective period during which the device may be stored without hardening of the polish. The polishing device .21 may be otherwise fabricated in the same manner as the preferred form thereof.
The wrapping material 19 for the envelope or wrapper 18 is preferably a sheeting which has a high resistance to the passage of the solvent used in the polishing substance such as metal foil, plastic film, coated or foil lined paper, or any other heat scalable material which is capable of forming an hermetically sealed container for the device.
A satisfactory method of fabricating the polishing de vice is illustrated in Figures 7 and 8. Two exterior webs of paper 31 and 32 are fed into superimposed relation with a thermoplastic web 33 between a pair of embossing rolls 34. The embossing rolls 34 apply to the surface of the webs 31 and 32 an embossing or creping to provide a two way stretch in the web material. The rolls 34 may be heated and arranged to apply pressure to the composite web so as to adhere the exterior webs 31 and 32 to the inner or binder web 33. The composite web isthen passed between a polish applicator roll 35'and acooperating back up roller 36 for application of continuous lines 37 of the polishing substance, the applicator roll 35 having applying bands 38 in encircling relation on the periphery thereof and spaced axially so that continuous stripes 37 of the polishing substance are applied in transversely spaced relation on the uppermost. surface of the composite web. The applicator roll 35 is provided with a doctor roller and fountain arrangement as indicated at 39. The composite web with the stripes or lines 37 of polishing substance applied thereto isv fed to a folding or pleating mechanism which comprises a pair of cooperating disc carrying rollers 40 between which the web passes and which folds the same on lines 41 extending longitudinally of the web between the transversely spaced stripes 37 of the polishing substance. From the folding rollers 40 the composite web is passed to a pair of cooperating compacting rollers 42 which bring the folds together and form a relatively narrow. folded strip of the material as indicated at 43. The strip 43 is cut by a severing mechanism 44 into sections which form the individual polishing units 45; each in accordion folded condition. The polishing devices or units 45, in their folded conditon, are fed across a guideway or magazine 4'6 0 a Wrapping mechanism 47. The units 45 are fed successively by a reciprocating pusher 48 between a pair of article spacing and web feeding rolls 49 between which webs of wrapping material 50 are also fed into superimposed relation with the units 45 being fed between the webs at spaced intervals. Thereafter. the assembly advances to a pair of sealing rollers. 51 which heat seal the side edges of the webs 50 and at longitudinally spaced intervals apply a cross seal between the units 45toform a series of connected packages 52.- which are separated into single or multiple package units as desired by reciprocating knives indicated at 53. Both the forming and packaging mechanisms are provided with suitable guides for supporting the variousmaterials in assembled relation as the. successive operations are carried out. a
