M. HOPP TRANSFER SET Filed June 24., 1936 ilt- 4 1N VENTOR.
ATTORNEY.
Patented Dec. 15, 1936 UNITED STATES atr a PATENT FFEQE Application June 24,
4 Claims.
This invention relates to copying units or printed transfer sets having carbon or equivalent sheets incorporated therein.
One object of the invention is to provide a 5 transfer set having improved means for the convenient simultaneous removal of the writing sheets from the carbon sheet that is bound thereto, the removal being effected without requiring detachment of the carbon sheet from the binder portion although the several sheets are coextensive throughout and cannot therefore be gripped independently of each other, and the possibility of the very thin carbon paper tearing haphazardly being guarded against.
Another object of the invention is to provide a bound transfer set wherein the writing and carbon sheets are all of uniform oblong size, for neatness in appearance, and full typing area, and the carbon sheet being coordinated therewith in an improved manner for simultaneous removal of the carbon sheet and detachment of the binder portion from the writing sheets so that the latter appear like regularly finished sheets.
A particularly important object of the invention is to furnish a bound transfer set having an improved arrangement and association of the bound writing sheets and carbon sheet so as to permit simultaneous severance of the writing 30 sheets near the binding and severance of the carbon sheet near the bottom end of the set, and permitting the set to be held in the typewriter to its very bottom end with the carbon sheet as well as the writing sheets secured against slippage.
An end portion of the carbon sheet that may not be thus removed can be discarded by holding the opposite end of the writing sheets and shaking the same, thus affording a new, improved operation.
Other objects and advantages of the invention will become apparent as the specification proceeds.
With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described in their preferred embodiments, pointed out in the subjoined claims, and illustrated in the annexed drawing, wherein like parts are designated by O the same reference characters throughout the several views.
In the drawing:

transfer set in course of being severed or separated.

It will be obvious to those skilled in the art to which the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawing, therefore, is submitted merely as showing the preferred exemplification of the invention.
Generally described, this invention provides a transfer set having bound to the upper edge thereof a carbon sheet whose bottom edge portion is weakened at one or more points and extends to the bottom edge of the writing sheet at other points, for the combined purpose of permitting the carbon and writing sheets to be held in a typewriter as a unit at their lower edge so that the writing sheets can be fully typed, and to permit the carbon and writingsheets to be readily separated when grasped at their lower ends and pulled against the binding. The writing sheets may be arranged in any suitable manner so as to be detachable from the usual binding of the transfer set by the pull exerted as aforesaid to separate the writing sheets from the carbon sheet. To afford a finger grip area at the binding, the writing sheets may have lines of weakness spaced from the binding. The lines of weakness in the writing sheets are a series of smooth edge forming slits, and the line of weakness in the carbon sheet is a series of perforations which do not unduly weaken the same.
Referring in detail to the drawing, [0 denotes a transfer set embodying the invention. The same may comprise a pair or more of writing sheets, for instance, an original sheet H and a copy sheet 52. Each sheet may carry suitable printing, as, for example, a heading l3 spaced from the upper edge, and a series of straight guide lines E l providing transverse rows and longitudinal columns for entries. The writing sheets M, 2 may each have a transverse line of weakness 25, such as a line of slits. The same is disposed above the printing and in suitably spaced relation to the upper edge of the sheets.
Interposed between the writing sheets, in alternation therewith, are one or more sheets adapted to transfer writing, such as the carbon sheet H5. The different sheets H, [2, it are bound together by aconventional line of adhesive or by any adhesive or detachable binder l1, along the upper edge of the transfer set. To facilitate the adhesive connection, the carbon sheet may have an upper edge portion Ila free of carbon deposit.
The lower edge of the carbon sheet may have a generally diagonal line of weakness such as a series of perforations at one or both corners as at 18, and being in coincidence throughout as at IS with the bottom edge of the uniformly oblong transfer set. The line of weakness 18 leaves a corner l8a sufficiently large to permit a convenient grasp of the transfer set, as indicated at 20, without grasping the main body of the carbon sheet Hi. In this respect, it may be mentioned that the portion of the transfer set above the line of weakness I is sufficiently wide or broad to permit it to be easily grasped as shown at 2|.
It will be noted that the printing 14 extends downwardly into close proximity to the bottom edge of the transfer set. Differently stated, the writing sheets include a lower usable or printed portion 22 projecting downward of the line of weakness [8, and which would represent waste if any sheet were cut away thereat. An anchorage is afforded at the typewriter roll so that the bottom rows of printing can be filled in on the typewriter. In so doing, the carbon sheet I6 is securely held because its lower edge at l9 extends substantially to the bottom edge of the transfer set. The perforations at l8 are sufficiently small not to interfere with the transfer action. And by providing the line of weakness l8 the transfer set can be separated as in Fig. 2, without requiring undue wastage of paper at 22, and permitting the writing sheets to be kept rather small in size.
By this invention, the writing sheets, when separated, are regular and oblong in shape. Further, the act of separating the different sheets serves to separate the writing sheets from the binding portion.
The transfer set can be used in a typewriter in a conventional manner. The different sheets may be wholly free of each other, except for the binding.
The latter and the lines of weakness l5 may be regarded as a detachable means. More specifically, the strip portion 23 of the writing sheets together with the binding or independently thereof may be regarded as means detachably interconnecting the carbon and writing sheets. Generally speaking, the line of weakness at I5 is somewhat weaker than that at I8 because the writing sheets are stronger or thicker than the carbon sheet. The carbon sheet and the parts ll, 23 attached thereto, as in Fig. 2, may be discarded. The part lBa may be discarded by grasping the writing sheets at their upper end after removal of the carbon sheets and merely shaking the part |8w loose.
In Fig. 5, I provide a modified carbon sheet 24 which is exactly like that shown at I6, except that the carbon sheet may be perforated or weakened along a line 26 providing a detachable portion 26a which corresponds to that at Him. This arrangement permits the bottom portion of the set to be grasped at any point instead of at a corner only, as shown in Fig. 2.
The line of perforations 18 may be variously arranged and located, but is most convenient at a corner. If a line of slits were employed in the carbon paper, the latter would become practically severed and hence unduly weakened. If a line of perforations were used at [5, the writing sheets would be difiicult to sever, and would present an unfinished top edge as at 21. More important still, since there are two writing sheets for the single carbon sheet, the lines of weakness 85 must be weaker than the lines of weakness at 28 and 25, because the total pull required to sever the Writing sheets should not be greater than that required to sever the carbon sheet, for the reason that a minimum pull is preferable to avoid possible slippage between the writing and carbon sheet faces during the pulling action. slippage, if it occurred, would cause the copy sheet 13 to be soiled. If desired, the lines of weakness at E3 and 26 may have a series of slits with a plurality of perforations intervening between the successive slits.
I claim:
1. A transfer set including a plurality of writing sheets, a carbon sheet disposed therebetween, an adhesive binding along a top edge of the set interconnecting the sheets, the sheets being free of each other at the opposite edge of the set, the carbon sheet having a diagonal line of weakness at a corner thereof at said free edge, the writing sheets extending beyond the line of weakness at said corner and the sheets being coextensive with each other at said free edge, the writing sheets each having a line of weakness spaced from but in relative proximity to said adhesive binding, the carbon sheet being otherwise of uniform strength throughout, whereby the carbon sheet can be removed by grasping the set at the bound edge and at the said corner thereof.
2. A transfer set including a plurality of writing sheets, a carbon sheet therebetween, a binding along the top edge of the set detachably interconnecting said sheets, the writing sheets having lines of weakness in relative proximity to the binding and generally parallel therewith, the writing sheets having printed guide lines therealong extending substantially to the bottom edge thereof, the sheets having a bottom portion that can be held in a typewriter while typing down to the end of the guide line, the sheets being free of each other at the bottom and side edges of the set, said carbon sheet having a diagonal line of weakness at a corner, extending upward of said guide lines, and the bottom edges of the sheets being coincident with each other, with the writing sheets projecting beyond the line of weakness at the corner of the carbon sheet.
3. A transfer set including a plurality of writing sheets, a carbon sheet therebetween, means detachably interconnecting the carbon sheet with the main body of the writing sheets along one edge of the set to permit the main body of the writing sheets to be removed from the carbon sheet by exerting a pull on the set, the carbon sheet having a line of weakness at the bottom edge of the set opposite to the interconnecting means, the line of weakness being sufficiently spaced from the bottom edge of the set to permit the set to be grasped wholly below the line of weakness, and the carbon sheet and the writing sheets having their edges at said bottom edge of the set in continuous substantial coincidence with each other from corner to corner of the set and to permit the carbon sheet as well as the writing sheets to be reliably held and fully typed in a typewriter adjacent to said bottom edge of the set, and the writing sheets being free of any lines of weakness adjacent to the bottom edge thereof.
4. A transfer set including a plurality of writing sheets, a carbon sheet therebetween, means detachably interconnecting the carbon sheet with the main body of the writing sheets along one edge of the set to permit the main body of the writing sheets to be removed from the carbon sheet by exerting a pull on the set, said means including a line of slits in the top of each Writing sheet in sufiiciently spaced relation to the top edge thereof to permit the set to be grasped above the lines of slits, the carbon sheet having a portion thereof perforated near 15 the bottom edge of the set opposite to the interconnecting means, the perforations being sufliciently spaced from said bottom edge to permit the writing sheets to be grasped between the fingers below the perforations, and the carbon sheet and the writing sheets having their edges at said bottom edge of the set in substantial coincidence with each other to permit the carbon sheet as well as the writing sheets to be reliably held in a typewriter at said bottom edge of the set, and the latter to be fully typed throughout, the carbon sheet and the writing sheets being respectively free of lines of weakness at their upper and lower portions.
