Application September as, 194:, Serial No. 503,54: Claims. (or. 101-431 This invention relates to a duplicator or re is one object of the inpanion sections so arranged and of such nature 1 that when properly writing or the like type folded the sheet may have d or otherwise inscribed thereon and the inscribed sheet then passed.

through a duplicating machine and copies of the inscribed sheet reproduced.

' Another object of the invention is to provide a duplicator sheet including a master sheet,ra car- "bon sheet, and an anti-smudge sheet which serves to prevent the carbon sheet or section from smearing the master sheet or matter jinscribed thereon, the sections that by properly may be disposed -the anti-smudge Q, the master" sheet or sheets being so arranged folding them, the carbon sheet back of the master sheet with sheet therebetween to protect before use and while being'carried to a duplicating machine, the carbon sheet being disposed between and the rear face of the, master coated surface confronting the master sheet while inscribing matterupon master sheet, and the m to dispose it rearwardly the anti-smudge sheet with during passage of th duplicator sented outwardly the anti-smudge sheet the front face of th aster sheet being turned of the carbon sheet and its rear face prethrough a duplicating machine.

Another object of the invention is to so form and arrange the sheets or sections that while inscribing matter upon the master sheet a portion of the anti-smudge sheet may be disposed .between the carbon sheet and the rear face of the master sheet upon the front face of and thus act as a shield to prevent predetermined portions of matter inscribed the master sheet from being reproduced upon the rear face of the master sheet. Y

Another object of the -a sheet of the invention is to provide character described which includes a plurality of sections permanently ena d? with each other so that they will always be ready for use, a marginal portion of the carbon sheet being left uncoated so that soiling of a persons hands by contact with the coated surface of the carbon sheet will Another object of the device of this character struction, efficient in manufacture.

Figure 9 is a view similar to Figure 7 looking at the exposed rear face of the master sheet.

Figure 10 iliustrates a slightly modified construction. This improved reproducing sheet consists briefly of a master sheet I, a carbon sheet 2 and an antismudge sheet 3. These sheets or sections I, 2 and 3 may be formed from a single sheet of paper which is creased to'set oil the sheets or sections oil! from the remainder of the .scorIngIothatthisportionI or the anti-smudge sheet may be severed along posedincoveringanri removed from original condition so that the anti-smudge sheet shielding relation to the coated surface of the carbon sheet while the remaining .portion of the anti-smudge sheet is disposed back of the carbon sheet and the exposed portion of the coated face of the carbon sheet engaged the rear face of the master sheet. while there has been shown one portion 3' it is to be understood that additional portions of this nature may be provided by properlyv scorin the anti-smudge sheet.

The duplicator as manufactured and supplied to the user is folded as shown in Figures 2 and 3 to dispose the master sheet anti-smudge sheet between the master sheet and the coated surface of the carbon sheet. Since the coated surface of the carbon sheet is disposed inwardly, the carbon will not be rubbed off or soil at the front and the the anti-smudge sheet with its rear face presented rearwardly and since this face of the masterrsheet bears the reproduction of the subother sheets of a stack of duplicators. when the duplicator is used the operator grasps the carbon sheet by the uncoated edge portion 2 thereof and turns it to the position shown in Figures 4 and 5. In this position the carbon sheet is disposed between the anti-smudge sheet with its coated surface confronting the master thereof. 2' of carbon sheet to be understood-that the carbon sheet may be ofsuch width that its uncoated edge portion may be left flat as shown in Figure 10. with the duplicator so folded it may he placed in a typewriter or other suitable machine and data typed thereon, or subject matter may face of the master sheet with a pen or pencil. As subject matter is typed or otherwise inscribed upon the front face of the mastersheet a reproduction of the same in reverse will be produced upon the rear face of the master sheet by action While the-uncoated'side edge p rtion of the carbon sheet and since the reproductions on the rear face of the master sheet are directly back ofthe originals on its frontface they will occupy the same positions in the form marked in reverse uponthe rear face that they do in the form upon the front face. 1

After the subject upon the front face of the master sheet, it is the typewriter will be disposed between the carbon sheet and the rear face of th master sheet and prevent smudglng of the rear face of the master sheet. Figure shows master sheet and an anti-smudge sheet cut to form a recess I through which the lower end of be inscribed upon the front "iect matter in carbon and a sheet of P p r to receive thc copy is disposed against this face of the master sheet; pressure of the duplicating machine as the duplicator and the sheet of paper are sheet and the master' sheet and bearing against the rear face 2 has been shown folded, it is adjoining corner portionsof the portion 2' is exposed. This permits the carbon sheettobe readily grasped by its lower free corner and the sheets easily turned from one posl-- tion of assembly to another. In caseit is desired to. prevent certainportions 0f pon the rear face thereof. the antismudge sheet is severed along lines anda portion 3' of the anti-smudge sheet disposed in m te thesubiectmatter typed n e mas 1' sheet from being reprom5? front of the carbon sheet, as in Figure 6. V

and since' the anti-smudge treated to prevent carbon from reproductions of subiect matter of the master sheet in front of the anti-smudgev sheet will a face oftnis portion-of-the anti-smudge sheet. It will thus be seen that both'facea of the anti-smudge 'sheetwill at all timesbe' free from carbon and cannot cause the master sheet or other sheets tobe smudged or "otherwise M disfigured by carbonadheri g'to it. In order to make a reproduction of sheet "is chem callyupon the portion.

the por on 3' of i pear upon the rear anti smudge of the producing matter the mat is 2. a duplicator comp 'sheet and the carbon initially folded alon sheet markings inscribed the master sheet, and the duplicator being also sheet back of the exposed for re-' fromtherca'rfaceofthemastersheet it will cause an impression oi the pas ed through subject. matter paper. An exact copy of the subject matter typed or otherwise inscribed upon the master sheet will thus be reproduced upon paper. Numerous copies may. thus be produced by repeatedly passing the duplic tor and a sheet of paper through'a duplicating machine. After a sufllcient number of copies have been made, the master sheet is refolded to its initialposition and the duplicator may b put away for future use.

From the foregoing description, the construction and operation of my duplicating form will be readily understood and it will be seen that I have provided a comparatively simple, efficient means for carrying out jects of the invention. I
