My invention relates Vto improvements in carbon copying systems, and more particularly to that type of copying system intended to be used in connection withv typewriters,
calculating and tabulating machines, and
oilice recordin machines of a similar nature.
Several di erent kinds or varieties of printed manifolding forms are manufactured at the present time and sold to customers, all ofv which have sheets of Acarbon paper, or transfer sheets as they are called in the trade, inserted betwee'n the original and each one of the copy sheets. As each customer uses a'series of forms adapted to his particular line of business, these forms must be printed to order, and thus the business of printing and selling these manifold forms with carbon included is highly specialized and expensive. An object of my invention is to provide a carbon copying system with the carbon or transfer sheets arranged in sets andA independentv of and separate from the copy forms, whereby these carbon sets become standard, and may be used with any kind of printed forms, for any reasonable number of copies, from one up, and whereby the same set of carbon sheets may be used with plain paper, if desired.
A further object of my invention is to provide a simple and practical set of carbon sheets which will permit the use of manifold and fold-pack forms in the ordinary typewriter or similar machine, without requiring fafny changes in or addition to the machine itse Another object of my invention is to provide a set of transfer sheets secured together in such a way as to allow for easy insertion or removalof the copy sheets, and also to allow the copy sheets to be pulled through the transfer sheets, thus permitting the transfer sheets to be used repeatedly until their utility has been exhausted. With the eigisting forms of manifolding sheets with transfer sheets included, the transfer sheets are torn oft` and discarded after beingused once. `It
, will be understood that by using the transfer sheets over and over, until exhausted, a large saving in cost is realized.
These and vother objects and advantages of my invention will appear in the following specifications with reference to the drawings and appended claims.
Broadly, my invention comprises a p1urality of transfer sheets, a reinforcing sheet of plain paper relatively lon er than the transfer sheets, means for securmg the trans.

Fig. 10 is a sectional view on the line 10- 10 of F 8, and
Fig. 11 is a diagrammatic sectional view indicating the method of stopping and holding the transfer set between the platen and Referring to the drawings 1n detail, in which like numerals refer to like parts throughout:
A transfer or carbon sheet 1 is formed with the strips or flaps 2 extending beyond the opposite side edges 3. A part ofthe sheet 1 near the top edge 4 is cut out or removed, as shown at 5. The sheet 1 is formed with spaced openings 6 corresponding to spaced openings in the copy forms, for the purpose of aligning transfersheets and copy sheets. The reinforced bottom edge of the sheet 1 is for the purpose of strengthening this edge and to facilitate the entrance of the top edge of a copy sheet, and is formed by folding a portion, indicated at 7 of the sheet 1 backward on itself through 180 and creasing it on the line 8. A plurality of carbon transfer sheets 1, 11 and 12`\are secured to each other and to the reinforcing sheet 9 by means of the stitches 10. The reinforcing sheet 9, as shown, is longer than the transfer sheets 1, 11, and 12, and is secured to the transfer sheets with its top edge 11 flush with the top edges 4 of these sheets, thus'leaving a portion 12 of the sheet 9 projecting below the bottom and folded edges 8 of the sheets 1, 11, and'l. The carbon transfer sheets 1, 11, and 12, are each made relatively longer than the precedin sheet, and, as they are secured together with their top edges 4 flush with each other, each of these sheets projects slightly below the sheet immediately above, as indicated at 14, thereby greatly aiding or assistin in the operation of inserting the indivi ual copy sheets, 15, of paper.
The transfer sheets 1, 11, and 1*, and the reinforcing sheet 9 are formed with rounded corners 13 at the intersection of the side edges 3 and top edge 4. The purpose of these rounded corners is to permit the square corners of the copy sheets to be visible outside of the round corners 13 for the purpose of accurate alignment of the copy sheets and transfer sheets. Also, to permit the operator to grasp the projecting ends of the copy sheets for their removal combined guide and stop strips 16V (see Fig. 7 are secured at the sideedges 17 of the projecting portion 12 of the reinforcing sheet 9 by the threads 10.
,These strips 16 are formed with the marginal acing stri 18, wed -sha at both ends 1g, and the integral aigid inwlfrddly extending guide flaps 29, thus forming a groove or channel 21, through which the side edges 22 of the copy sheets 15 are drawn as the are pulled eets.
' the typist. When the record has been completed, the typewriter will have fed the copy and transfer sheets upward until their bottom edges are approximately opposite the center of the platen 23, as indicated in Fig. 5 and Fig. 6. In this position, the wedgeshaped end portions 19 of the guide and stop strips 16 have engaged the platen 23 and friction rolls 24, thereby preventing the transfer sheet from being drawn Vupward any farther by the revolutions of the platen. The tension on the platen is now released, which permits the wedge-shaped portions 19 to enter a little farther into the space 25 between the platen 23A and friction rolls 24, thereby relieving all pressure on the copy sheets 15. In this position, 'the copy sheets 15 may be easily and quickly'pulled around the platen and through the transfer sheets, the latter held in position by the engagement of the side stop strips 16 between the platen 23 and the friction rolls 24. The copy sheets 15 are grasped in the area 5 and pulled upward, without causing any strain on the transfer sheets, until the line of weakness 26, indicating the bottom of the typed set of copy sheets, clears the top edges 4 and 11 of the transfer set and backing sheet 9. The platen is then revolved in the opposite direction, returning the to of the transfer sheets and new set of copy s eets to a printing position; the typed set of copy sheets are then torn off, and another record typed on the new set of copy' sheets.
YIn the modified form of my invention, illustrated in Figs. 8, 9, 10, and 11, the transfer sheets 13, 11, 15, 1, .and 11 are formed in a similar manner as 1, 11, and 12, and are secured to a short backing strip 26 with the threads or staples 27. The top edge 28, shown in dotted -lines in Fig. 8, of the backing strip 26 is located a short distance above the top of the opposite side extensions 2. The spacing and aligning strips 29 are secured at each of the side edges of the backing strip 26 near the bottom edge 30, and a guide strip 31 is secured to the spacing strips 29 by threads or staples 291 and extends across and is spaced from the short backing strip 26. The upper edge 32 of the guide strip 31 is bent down toward the hacking strip 26', thus forming a resilient member for holding the forms or paper against the backing strip 26', when they are drawn through.v The side edges of the paper are guided by the strips 29 in a Y similar manner to the strips 16.
Theo ration is the same as that described for the evice illustrated in Figs. 1 to 7, incl.,
except the spacing strips 29 engage the platen 23 and back plate 33, thus preventing any further upward movement of the transfer set at their top edges, and combined guide and stop strips secured to the side portions of said reinforcing sheet which extend below the bottom edge of said transfer sheets.
