6 Claims. (Cl. 282-29) a portion of each sheet of carbon paper which cannot be used unless the same is taken out of the machineand inverted, this portion being that extending from the holder to which it is secured, to the platen of the machine, and the present invention has as an important object the production of a device by means of which this waste of carbon paper is eliminated, whereby a shorter sheet of carbon may be utilized, and which is entirely used.

Another object of the invention is the construction of such a device which may be used over and over again with a comparatively large number of sheets of carbon paper.

A further object of the in ention is the construction of such a device which securely holds the carbon paper and from which the same may be easily removed without tearing the paper or the like.

30 Another object ofthe invention is the production of such a device which is simple in construction and relatively inexpensive to manufacture.

Another object of the invention is the construc- 35 tion of such a device in which the carbon paper is structionherein shown and described will be ob- 40 vious to those skilled in the art from the disclo` sure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and iore par- 45 ticularly pointed o ut in the claims. Y

In the drawing wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a side elevational view illustrating the holders in use and showing a portion of a typical 50 machine upon which the same is to be used;

Fig. 2 is a plan view of the holder and sheet of carbon paper with a portion broken away to show the construction of the holder;

Fig. 3 is a side view of a holder with 9. Sheet 65 of carbon attached thereto; and

Fig. 4`is an enlarged sectional view of the holder with a-portion of the carbon paper.

Fig. 1 illustrates the device as used in on type of manifolding machine, l representing the pages to be filled in. Interposed between the 5 pages are relatively at rods 2 to which the ends of the carbon paper are ordinarily secured. The pages and the interposed sheets of carbon are then fed past the guide plate 3 and `around the platen l. As the pages of the manifold are fed 10 past the platen 4, the sheets of carbon paper will feed along withthem, and after a page has been completed, the paper release on the machine is manipulated, thereby releasing the pages, after which the rods 2 aredrawn away from the platen, thereby drawing the carbon paper back to its original starting position, which in this case, will then position the same in the next page to be filled in. This is accomplished for example by a lever 5 20 which is connected through a suitable mechanism to the rods 2 so that operation of the lever 5 will return the carbon sheets to their original starting position. After the carbon has been drawn back to the next page, the preceding completed page is removed from the machine. These pages which are ordinarily formed from a continuous strip of paper are perforated at their adjoining edges so that they may readily be disconnected from one another and removed from the machine.v The rods 2 will approach the platen as the page is lled in, and obviously, as the rods 2 cannot pass around the platen, but will reach the limit of their travel before. engaging the guide plate 3, there will be a portion of the car 35 bon paper extending from the rods 2 over the guide plate 3 and around the platen to the line of printing which will not be used unless the pagesl are taken out of the machine and the carbon paper turned around so that the unused portion will then be the first to enter the machine. Applicants device takes the place of the unused portion of the carbon paper and thereby eliminates wasting of the carbonV paper and the necessity of turning the same around in the machine, as well as enabling the use of carbon paper of a shorter length. v

As shown in Figs. 2, 3, and 4, the invention comprises a sheet oi paper 6 or other suitable material, which may or may not be suitably colored as desired, one end 1 of which is folded back K upon itself and stitched or otherwise secured at" -8 to form a pocket of a size to receive a rod 2, or if desired, may be held in place on the rod 2 by suitable clips or the like. This paper may be 55v in which it is to be used, the length being such as to utilize the entire piece of carbon paper 9 to which it is to be secured. The opposite edge of the sheet of paper I is provided with a.p1u rality of apertures Il which are preferably of triangular shape, the apex' l2 of the triangle being adjacent the free edge of the paper. Extending across each opening on one side of the paper is a piece of suitable ribbon` cement adhesive, the same preferably having a paper backing I3 with the adhesive Il adjacent the opening and also forming a means of securing the same to the paper sheet 6.

To use the device, the edge of the carbon paper 9 is placed over the opening Il with the carbon I8 on the upper or outside and the paper I1 down or on the bottom side adjacent the adhesive I l and aligned on the'sheet 6 by means of the guide line i5 printed on the latter. I'he adhesive material Il is non-drying or hardening so that the sheet 6 may be used over and over again. To'remove the sheet of carbon 9 from the sheet 6, the

carbon paper is merely turned' back over the sheet 8 and gently pulled therefrom. Due to the novel shape of the openings il, as the carbon paper is drawn back, only a very small portion of the adhesive surface isI removed at the start, the same increasing as the paper is removed therefrom. Thus, it will be seen that the carbon paper will be initially removed from a very small portion of the adhesive surface, increasing as the same is drawn away therefrom.` 'In other words, only a very small portion of the adhesive surface will resist the removal of the paper at the start, thereby preventing any tearing or the like of the carbon palper- It will be seen from the above descriptionthat I have provided a novel holder for carbon paper 40 which eliminates any shifting of the same or the necessity of turningthe paper around in the machine, and also allows the use of'a smaller sheet of carbon than has heretofore been used in this type of machine. Likewise, I have provided novel 45-means for seeming the' carbon paper to the holder whereby the same may be readily removed without tearing thereof.

Having thus described my invention, it is lobvious that various immaterial modifications may 50i-be made in the same without departing from the spirit and scope of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and com bination of parts herein shownand described or 5 uses mentioned.
