3 Claims. (01. 282-22) This invention relates to booklets wherein original and carbon copies may be made and to special transfer sheet arrangements and correlated top cover structure in such booklets.

It is a major object of the invention to provide a booklet containing original and duplicate pages in succession and wherein a novel arrangement of carbon sheets is provided so that there is always a bound-in fresh or usable transfer sheet available for insertion between the pages.

A further object of the invention is to provide a novel booklet wherein a plurality of transfer sheets are bound into the booklet above the pages.

A further object of the invention is to provide a novel booklet wherein a plurality of transfer sheets are bound into the booklet above the pages and a special folded top cover contains the transfer sheets not in use while permitting insertion of the lower most sheet between two pages.

Figure 1 is a section through a partially open booklet according to a preferred embodiment of the invention;

Figure 2 is a front elevation looking into the open end of the partially open booklet;

Figure 3 is a section on line 3-3 of Figure 2 illustrating the bound edge enlarged;

Figure 4 is a section like Figure 3 but with the lower carbon sheet slipped between the pages a of the top folded paper slip; and

Figure 5 is a top plan view of a closed booklet with the cover partly cut away.

The booklet comprises a relatively stiff rectangular sheet of cardboard or the like II beneath which lies a thinner coextensive sheet of cardboard or the like I2. Sheet II is sufliciently stiif to serve as a rigid backing for the booklet during writing, and may be of low grade unfinished cardboard. Sheet I2 is essentially a bottom cover of finer surface which adds to the stiffness, but is intended chiefly to improve the appearance. If desired sheets II and 12 may be replaced by a single adequately stiff and finished sheet of cardboard or the like.

superposed above base I I is a stack of identical folded paper slips I3 each comprising a top original page I4 and a bottom duplicate page It of the same size connected at their outer ends by a serrated hinge portion Iii. The inner ends of lower pages I5 extend beyond the inner ends of pages I4 into a binding area H where they are tightly secured together as by staples I8 which also pass through base II and bottom cover I2. outwardly of staples I 8 and underlying the inner edge of page I4 each page I5 is formed with a perforated score line I9 so that it can be torn out of the booklet evenly with page I4.

Above the uppermost slip I3 a plurality of identical carbon transfer sheets 28 are bound into the stack by staples I B. These carbon sheets which may have lines across their inner ends near the binding I1 have their transfer surfaces on the bottom. Abovethe top carbon sheet 20 a top cover assembly comprising cover sheet 2| which is thicker than pages I4 or I5 and preferably of about the thickness and finish of sheet I2 is bound into the assembly by staples IS. The entire assembly is rectangular with all sheets and pages being of the same dimensions in plan, except for top cover 2I which at its outer end is folded at 22 to provide an undercover 23 that extends back under the carbon sheet section and terminates at about the level of score lines I9.

When the book is first purchased, all of the carbon sheets 2!] are contained by the top cover 2I and undercover 23 as illustrated in Figure 1. In starting use of the booklet, see Figure 5, the lowermost carbon sheet 20 is slipped out from undercover 23 and inserted between pages I4 and I5. The other carbon sheets 20 remain enclosed within the folded top cover assembly, and the user may write upon the top surface of original page I4 while producing a carbon duplicate on page I5.

After the top slip I3 is completed, it is removed from the booklet by stripping of page I5 at score line I9, and then the same lowermost carbon sheet is available to be slipped into the next top slip I3. This is continued until the lowermost carbon sheet 20 is used up or exhausted, at which time it can be torn out at binding I1, and the next lowermost carbon sheet is now available to be slipped out of the cover and used in the above fashion.

In this manner I always have a fresh or usable sheet of carbon available for each top slip I3. This is a great improvement over prior booklets of this type wherein only a single carbon sheet was bound in above the top slip with a few other carbon slips bound in at intervals between predetermined numbers of slips on the theory that each carbon slip would remain usable until the next bound-in carbon slip was reached. If the top carbon sheet in such prior booklets became damaged or useless, there was no bound-in carbon sheet available for the top series of folded slips and the messy slow operation of improvising and inserting a loose carbon sheet was necessary.

During the entire life of the booklet, the unused reservoir of fresh carbon sheets is held within the top cover assembly and only the carbon sheet being used is free. The undercover 23 not only enfolds the carbon sheets. not in use 7 but it protects the users hands from smearing on the undersurface of the lower carbon sheets in the reservoir.

The invention may be embodied in other speci fie forms with departing'from the spirit or essential characteristics thereof. The present embodiment istherefore to be considered in all re-- spects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description,

and all changes which come within the meaning and range of equivalency of the claims are there-; fore intended to be, embraced therein.

1. In a booklet, a stack ofpaper slips comprising a botton'r leaf having its inner endheld in a binding and its outer end connected along a fold line 'to the outer end of an. upper leaf that has a free inner end terminating adjacent said binding, a plurality of superposed transfer sheets held at their inner ends in said binding above said stack of slips and having individually free outer ends, and a top cover assembly having an forated tear portion adjacent the binding.
