My invention relates to a carbon copying set and refers more particularly to the means for removing carbon sheets from the set without disturbing the original and copies.

One object of my invention is to provide an original and a multiplicity of copy sheets with carbon sheets interposed between that can be easily removed without disturbing the copies and original. Another object of my invention resides in the form of the copy sheets.

A further object of my invention consists in the form of the carbon sheets.

Another valuable feature of my invention consists in arranging leaves after they are cut at the proper places and made up into a set as illustrated so that all of the copy sheets may be held with the lingers of the left hand and all of the carbon sheets may be held by the fingers of the right hand.

It is well known in the art that groups of copy and carbon sheets have been used but none incorporate the unique form or construction utilized in this particular set or have the same organization of elements utilized for the specific purpose of this set.

I accomplish this result by the means illustrated in the accompanyin drawings, where- 1n similar numerals re er to like parts $0 throughout the several views, in which Flgure 1, is a plan illustrating the arrangement of the set. v

Figure 2, is an enlarged detail taken on lines 2-2 of Figure 1.

. Figure 3, is an enlarged detail taken on lines 3 3 of Figure 1.

The ori al sheet 1, copy sheets 2, 3, 4 and 5,-and car on sheets 6, 7, 8 and 9, are all perforated at-10 and 11, and fastened together by the clips 12 and 13, all sheets having single holes 14 and 15 throu hall of the leaves, for hanging up and each of the sheets eXce t the. carbon sheets are provided with suitab e ruhngs and printed notations.

preferably cut away diagonally at the upper left hand corner and all of the carbon sheets 6 to 9, in flusive are cut away diagonally at the lower right hand corner. The carbonsheets are coated with a suitable All of the copy sheets 1 to 5, inclusive are 1928. Serial No. 277,579,

non-smearing carbon copying coating from 17 to 11, and all the carbon and copy sheets are plain, with no markings, above the perforations 10 and below the perforations ,11.

In operation, the group or set of sheets are placed in the typewriter or written upon by hand, after which the stub 20 is removed and the 'fingers of the left hand grasp all of the copy sheets in the corner space 18, and the lingers of the right hand grasp all of the carbon sheets in the corner space 19, whereupon, j by pulling the carbon sheets diagonally with the right hand, holding the original and copy sheets with the left hand, all of the carbon sheets can be easily removed from their place G5' between the copy sheets, after which the top part 20, andthe lower part 21, may be torn 'olf on the perforated ylines 10 and 11.

' Having thus described and illustrated the preferred embodiment of my invention I do not wish to limit myself to the exact construction or arrangement of parts shown, since it is evident that modifications may be made` therein without'departing from the spirit of the invention or scope of the claim. '75 I claim v The combination in a carbon copying set of an original sheet and a copy sheet, each cut away at one corner, and a carbon sheet interposed therebetween, cut away at the opposite corner, all of said sheets bound together and provided with lines of weakness above one cut, and within the other cut.

Signed at New York, in the county and State of New York, this 11th day of May, 85
