April 5,1932- T. A. GREEN RENEWABLE SURFACE DUST CLOTH 'Filed Dec. 27, 1929 Patented Apr. 5, 1932 THORNTON A. GREEN, OF ONTONAGON, MICHIGAN RENEWABLE SURFACE DUST CLOTH Application filed December 27, 1929. Serial No. 416,8),1.
This invention relates to dust cloths and more particularly to a paper dust cloth having a plurality of fresh cleaning surfaces which are successively available by stripping off the outermost one.
It has been more or less customary in this art to utilize dust'cloths of fabric or dust cloths having only a single cleaning surface so that when the surface is soiled from use the dust cloth must either be discarded or washed, or refolded to expose-a partiallyclean surface but in each of these cases economy is not secured and the dirt or grease which is removed from the surface being cleaned is very likely to be rubbed into the next portion of the surface or another surface being treated so as to manthe same or result in an ineflicient cleaning of the same. These disadvantages are all eliminated by the present invention which additionally pre sents advantages of its own peculiar to its nature and composition.
In a general way, the present dust cloth is composed of a comparatively thick body of loosely matted fibers arranged in a number of very thin superposed layers each of which readily separates from the under-lying layers merely by stripping off the same. In this way a dust cloth of a given size can be utilizcii very economically and for a' much greater surface or area to be cleaned even than a plurality of dust cloths of the known types, and as each outermost layer becomes soiled a fresh under-lying layer canbe readily made available by simply stripping off the outermost soiled layer. In addition the dust cloth may be and preferably is impregnated with any suitable or desirable wax or ,oil or the like for the usual purposes.
The drawing illustrates a perspective view of a preferred embodiment ofthe invention,
several of the layers being partially turned.
backto show more clea'rly'the manner in which the dust cloth is made.
' Referring now particularly to the drawing in detail the dust cloth is indicated in its,
entirety by the numeral 10. The dust cloth may be of any appropriate size and shape and the particular embodiment shown is apsurface being cleaned or dusted. 'avcon dition is reached the soiled layer can readily be picked up at one of its corners by proximately twelve inches in length and of about the same width.
The material of the dust cloth is, as has already been stated, paper and composed of a plurality of superposed and meshed thin fibrous loosely'compacted layers 11. -Each layer is relativelyvery thin and absorbent due to its loose texture which may be called anincomplete unsized paper web. The dust cloth may be formed by rolling into a large roll a considerable length of the loosely compacted fibrous web and from the large roll thus formed portions of suitable size and thickness may be cut out to any desired de th of material, thereby determining the num er of layers in a given dust cloth and hence the number of fresh cleaning surfaces.
Each dust cloth may thus consist of a number of thin layers and in practice the number of layers may run anywhere from a comparatively small number as 5 or 6 to a comparatively large number say 25 or '50 or even more. y
The loosely compacted fibrous web may be impregnated with a wax or oil at any desired stage in its formation but one convenient manner of impregnation has been found to-be that of spraying or atomizing the oil or wax in a liquid condition onto the paper Web as it comes from the forming roll. It is clear however, that the impregnation could be performed at other points in the formation of the dust cloth-as by incorporating the materials in the vat or Jordan machine in which the pulp is mixed or even by exposing the dust cloths or rollsof fibrous material before they are cut into dust cloths to the vapors or other action of the wax or oil under suitable conditions, i i p In use, a dust cloth' say of approximately 12 by l2inches is manually manipulatedover the surface to be cleaned such as that of furniture, automobiles,flo ors, glass or the like until the outermost surface which is being utilized for the cleaning operation is relatively dirty or soiled so that its "further'use would be inefiicient or even detrimental to the When such the fingers and stripped off leaving exposed therebeneath a clean surface immedlately ready for use. When this next layer is simi' larly soiled it may be stripped oil as was the first layer and the cleaning operation may be continued if desired until the dust cloth has been fully utilized or when the remaining layers become very few in number they may be readily added to another dust cloth of similar kind merely by super osing them thereon, whereupon the loose brous structure of one layer will in a measure adhere to the loose fibers of the'adjacent layers. In this manner there is no waste of material un-, der any circumstances and the cleaning operation can proceed without interruption.
A given thin loosely compacted web may be rolled into a large roll of considerable length in order that the loosely compacted fibres of each of the layers of the web thereby formed will intermeshhnd cling to the fibres of adjacent layers to form a loosely compacted but composite roll of polishing orodust cleaning material. To obtain a dust cloth of a desired length, width or depth, a. lanar section is cut across said roll to a dep responding to a desired number of layers of compacted webs.
These dust cloths can be made exceedingly cheaply so as to be Widely sold or dispensed at a nominal price and moreover the soiled layers are very easily disposed of and if desired a water soluble paperifiber may be used tlzhereby aiding the ready disposal ofthe soiled ayers. v
It has been found in practice that such a dust cloth as I have above described is very easy to utilize and the absorbent nature of the layers enables a relativel great amount of soiled matter to be heldjln therloosely compacted fibers; The advantages'are great and the dust cloths may be shaped to fit the hand and in any desirable shape so as to facilitater their use.
