. MANIFOLDING MATERIAL Application filed October 6, 1927. Serial No. 924,488.

My invention relates to "manifolding, and

more particularly to the provision of a car-.

' and is preferably of a light color distinctively different from the pigment of the carbon or transfer material, thus disguising and concealing the character of the coating of transfer material and simulating the appearance of an ordinary piece of record paper.

There is a rapidly increasing use of one time carbon or duplicating material for manifolding records. Usually the deposit of carbon or transfer material is applied di- 16 rectly to the reverse face of the record sheet.

Inasmuch as such record, data sheet and the like must be handled by clerks, auditors and accountants, such carbonized record sheets are objectionable since the material rubs off 20 soiling the hands of persons who may have to handle such records. Moreover, when such carbonized sheets are superposed on each other there is a tendency for the faces of the sheets to become soiled and unsightly by their contact with the carbonized faces of adjacent sheets. Aside from the objection that such carbon material smudges, smears or rubs off, there is also an objection from an esthetic point of view to the dark color of the reversed sides of such carbonized record sheets.

Two of the primary objects of the present invention are to provide a protective coating or sizing over the deposit of carbon or transfer material which will prevent smudging or smearing of the transfer material by frictional contact, but which will be sufiiciently yielding to permit the transfer material to be projectedtherethrough by the pressure incident to the writing upon the face of the sheet or on an overlying sheet and further to render such sealing coat opaque and of distinctively different color from the carbon or transfer material in order to disguise and conceal the deposit of transfer material and to simulate the appearance of the face or record receiving side of the sheet.

With the above primary and other incidental objects in View, as will more fully appear in the specification, the invention consists of 59 the features of construction, the parts and combinations thereof, and themode of operation, or their equivalents, as hereinafter described and set forthin'the claims.

Referring to the drawing, wherein is shown the preferred, but obviously not neces- 5 sarily the only form of embodiment of the invention, Fig. 1 is an enlarged or exaggerated detail sectional view illustrating the successive strata comprising the composite manifolding sheets. Fig. 2 is a further de- 00 tail perspective view illustratin the succes-' sive strata as though separate from each other to more definitely illustrate their relative arrangement. Fig. 3 is a perspective view of an original and duplicate record sheet, the carbonized undersurface of the original being upturned. Fig. 4 is an exaggerated detail view showing how the inter-- mediate stratum of carbon or transfer mate rial is projected through the sealing or sur- 1o face coat by the pressure of the pencil point. Fig. 5 is a detail sectional view showing the invention applied to typewriter operation.

Like parts are indicated by similar characters of reference throughout the several views.

While the present invention is primarily designed for the manufacture of original and duplicate record sheets by applying to the reverse sides of such record sheets the necessar material to transfer the writing or inscrlption from one sheet to another, it will be understood that it is applicable to duplicating or manifolding sheets to be interposed or interleafed between other original and duplicate record sheets.

In the drawing, 1 represents the record sheet or supporting sheet, which is preferably, though not necessarily, a printed form on which is to be entered in writing various data. Ordinarily such forms are provided in a continuous succession to be fed through an autographic register or typewriter in association with one or more un'derlyin sheets to which is to be transferred a dupllcate of the inscription impressed upon the topmost record sheet. While this transfer may be made by an interposed sheet of transfer or manifolding material the customary and preferable method, especially for billing and accounting purposes, and the like is to promottled appearance. To avoid such discolorvide upon the reverse side of such original ation of the face of the record sheet the reand duplicate record sheet a coating 2 of verse side of such sheet may be coated with a carbon or transfer material. In order to selight deposit of talc or similar material or by cure copies with minimum pressure it is necother suitable sizing in order to close the essary that the carbon or transfer material pores of such paper prior to the appllcation be of such character that it will be readily of the stratum 2 of colored transfer material. transferred to the contacting surface of the The sealing coat or stratum 3, as well as underlying record sheet 4. the interposed coating of talc or other opaque This same characteristic, however, causes 'material ay be appli d in arious ways. it to rub off upon the fingers of such persons Such sealing coat may be applied by fl twho necessarily handle such records and upon i th carbonized t k upon a b d of u h other papers and desk tops u on which such coating material in liquid form or it may be carbonized records ay be $11 sequently sprayed in liquid form upon the surface of To Overcome this characteristic of g g carbon or transfer material.

Various materials may be used for sealing the surface of the carbon or transfer stratum 2. This coating may be a thin coating of paraffine or other wax or of compounds havingparafiine or other wax base.

There is some objection by users to the appearance of such carbonized record sheet, the desire being for a sheet which will not be markedly different from an ordinary sheet of paper. In order to simulate the appearance of an ordinary record sheet and to disguise and conceal the deposit 2 of carbon or transfer material the sealing coat 3 is preferably rendered opaque. This may be done by incorporating a pigment or a filler material in such sealing coat. A suitable material for this purpose has been found to be talc which may be incorporated directly in the coating 3, but is preferably, though not necessarily applied to the surface of the deposit 2 prior to the application of the paraifine or other wax coatin Obviously other materials, such as chal or whiting may be employed in lieu of talc, or even materials of other terial sufiicient to disguise and conceal the underlying deposit.

It is to be understood that the present manifolding material is equally applicable to typewriter use. In such case the impact of the type face upon the surface of the uppermost sheet will displace the coating material by pressing it aside while thrusting the coating of transfer material into contact with the underlying sheet. While paraffine and other Wax havelbeen mentioned for illustrative purposes as preferable material it is to be understood that any other plastic material of suitable character of which many are available may be employed.

From the above description it will be apparent that there is thus provided a material of the character described, possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions and arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.
