Specification of Letters Patent.
Patented July 16, 1912.
Application filed August 19, 1910. Serial No. 577,967.
To all whom it may concern:
Be it known that I, ISAAC H. MALLIN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in CarbomSheets, of which the following is a full, clear, and exact specification.
y invention relates to improvements in carbon sheets which as ordinarily constructed are of rectangular, square or other form for adapting them for use'to different sizes and forms of paper to receive the carbon impressions therefrom.
Carbon sheets adhere more or. less to the sheets of paper upon which their impress is taken, with the result that before my invention their separationrequired that they must be pulled or peeled apart by the use of the thumbs and fingers of the operatorto such a disarrangement that. both must be rearranged for subsequent use on the one hand and convenient inspection on the other hand, and with an objectionable lossof time and exertion increasing with the 1 number of copies simultaneously taken, and aggravated when there is anecessity for quick and hurried work on the part of the operator of a typewriter in which carbon sheets are extensively used and in enormous numbers. The object of my invention is a carbon sheet so constructed that a separation besheets'and paper effected with ease and without any disarrangement of either, and whereby, when separated, both the carbon sheets and the paper sheets, however may be of the same impress, will be retained in their operative position'for further use and subsequent inspect-ion.
With these ends in view, my invention. finds embodiment in certain features of novelty in the construction, combination and arrangement of parts by and certain other objects hereinafter appearing are obtained, all as .fully described with reference- -to the accompanying drawing and more particularly claims.
In said drawing: plan view of a carbon sheet embo invention Figure 1 illustrates a y n y and Fig. 2 aside elevation of the many duplicates there which said objectspointed out in the I Similar characters of reference indicate similar parts in both figures of the drawing. 3 indicates a carbon sheet provided with parallel side edges 4 and 5, but instead of having parallel end edges 6 and 7 as before provided, one end edge is interrupted by a notch 8, and the opposite end edge by a tongue, 9. The notch 8 ispreferably located centrally of the width and is of such form and size as to permit. the passage of the thumb and finger without contact with the carbon sheet, while the tongue 9 projects be yond the impression surface of the carbon sheet and terminates at a point removed from the side edges of the sheet. The ends of the tongue 9 slope to their juncture with the sheet as indicated at 10-40 and preferably on reversibly-curved lines l0 l0, first-for the purpose of reducing its liability to be torn from thecarbon sheet; Second, to reduce its tendency to crease; and, third, to adapt the corners so formed for grasping close up to the carbon sheet a sheet of letter paper on a line diagonal to both for promoting their separation by a torsional strain upon each.
For the purposes of impression, acarbon sheet of my invention need not be carbonized throughout its surface, including the tongue, but preferably is for reasons of economy, in that it will require less expense to Carbonize the whole sheet than to omit a coating of carbon. at any particular point thereon. In operation, when it is desirable to s1- multaneously take one or more carbon sheets of a typewritten letter, the letter sheets and carbon sheets, however many there may be, are alternat-ely la id one upon the other wlth the letter sheet, projecting across the notch 8, but notiover the tongue 9, and are ma ntained in this position during the typewriting thereon typewriting machine. It will now be seen that if while in this position after removal, the several sheets of letter paper, extending across the notch, are firmly grasped between the thumb and index finger of one hand,
and the tongues of the carbon sheets are likewise graspedby the operator, the carbon sheets and the letter sheets, in any number either may be, will be simultaneously separated by pulling tions, and without, inanymanner, disturb and their removal from the them in opposite direcend, as must be done in order to utilize their sheets are grasped a entire surface, the letter sheets are shifted so that the type of the typewriting machine will strike" between the used spaces of the carbon sheet, and for this'purpose the last sheets are projected partly over upon the tongue of'the' carbon sheets, but not sufficiently to prevent clasping the ends of the carbon sheets and at the same time the letter sheets at the notch for their separation.
When separating them in the manner last above described, it should be observed that on taking hold of the-carbon sheets diagonally opposite thefl'oint where the letter jacent one end or the other of the tongue, a torsional or frictional strain will be exerted on the adhering surfaces facilitating their separation, and, in this connection, it may also be observed that when very fresh carbon sheets or those which have quite sticky surfaces are .employed, the letter sheetsmay be arranged as last described with reference to reversed carbon sheets.
It should be understood that my .inven-- tion is not limited to the exact form ofthe notch or the tongue nor to their relative location so long as they, or. either of them are of such form and arrangement that carbon sheets of an number may be simultaneously separate without disturbing the operative position of either the separated carbon sheets or letter sheets.
Having described my invention, what 1 claim and desire to secure by Letters Patent 1s:-
1. A carbon which are respectively pro'vided with a tongue and a notch whereby letter sheets and the'carbon sheets of any number may be simultaneously separated without disturbing the operative arrangement of either the separated carbon sheets or letter sheets.
2. A carbon sheet provided at opposite ends respectively with a notch centrally thereof and a tongue the ends of which terminate equidistantfrom the adjacent side edges of the sheet.
3. A carbon sheet provided at its opposite ends respectively with a tongue and a notch on a longitudinal line central of the width of said sheen substantially as, and for the purpose described.
In witnessWhereof, I "have hereunto set my hand and aflixed my seal-,rthis 16th day t of August A.-D.-1910..
