CARBON-SHEET HOLDER.

SPECIFICATION forming part of Letters Patent No. 660,142, dated October 23, 1900.

Application filed June 25,1900 Serial No. 21,452. (No model.)

To all whom it may concern:

Be it known that I, FRANZ A. BARTELMEZ, a citizen of the United States, residingin the city, county, and State of New York, have invented certain new and useful Improvements in Carbon-Sheet Holders,of which the followingis a specification sufficientto enable others skilled in the art to which the invention appertains to make and use the same.

My invention relates to holders for carbonsheets to be used in transferring copy to the page of a book or equivalent.

The object of the invention is to afiord a comparatively simple, cheap, and elfective device that may be discarded with the carbon-sheet to which it is attached when it is desired to replace the latter with a fresh carhon-sheet having its own holder. In other words, each carbon-sheet is attached to an individual holder of such economical construction that it maybe thrown away with the exhausted sheet, thereby avoiding the inconvenience and discomfort of attaching a fresh carbon-sheet to a holder from time to time, as heretofore required.

The invention consists in the special form and construction of parts attached to a carbon transfer-sheet and hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a blank representing my improved carbonsheet holder before it is folded upon itself. Fig. 2 is a top View of the holder folded, Fig. 3 is a view of the under side of the holder; Fig. 4, a transverse section, upon an enlarged scale, upon plane of line 4 4, Fig. 3, showing the holder folded, with the carbon-sheet and protecting-sheet attached to a coupling-strip. Fig. 5 is a view similar to Fig. 4, showing the holder open. Fig. 6 is a view similar to Fig. 4, showing an edge of a sheet of paper clamped in the holder, the carbon-sheet being in this case attached directly to the holder. Fig. 7 is an isometrical View of the holder open;

Fig. 8, a view of the under side of the holder,

In carrying out my invention I prefer to make the holder of a single piece or blank A, Fig: 1, of comparatively inexpensive materialas cardboard,stiff paper,or other fibrous material-although the device may obviously be made of metal or other relatively-costly material if preferred or designed for permanent use in connection with a succession of carbon-sheets. By making the holder of paper, cardboard, 850., it can be discarded with the depleted carbon-sheet to which it is attached, and of which it forms a part as an article of manufacture and trade.

The holder H consists of the lower plate or base h, to which one edge of the carbonsheet 0 and one edge of the protector-sheet p are attached, either directly or indirectly. Thus instead of attaching the carbon-sheet c and protecting-sheet p directly to the base It, as shown in Figs. 6 and 9, I prefer to interpose a coupling-strip s, of paper or other flexible material, said strip 3 being secured to the base it at one edge and overlapping the same sufficiently to afiord a margin s, to which an edge of the carbon-sheet c and an edge of the protecting-sheet 19 may be separately attached, as illustrated in Figs. 4, 5, and 8. The edge of the intermediate strip 8 being attached to the upper side of the base .h, the edges of the carbon-sheet and protecting-sheet are gummed to the under side of said strip 5, the edge 19 of the protectingsheet 19 being attached above the edge 0 of the carbon-sheet 0, so that the protectingsheet p may be stripped off without disturbing the carbon-sheet when the latter is desired for use, as indicated in Fig. 8. The strip s being of stronger texture than the carbon-sheet by its flexibility relieves the latter from undue strain in adapting itself to the requirements of use, it being obvious that a rigid connection between the comparatiyely thin fragile paper and the. substantially rigid plate his undesirable, although this direct connection of the carbon-sheet may be resorted to without departing from the spirit and intent of my invention and as indicated in Figs.-6 and 9.

The clip 71. for holding the sheet W to be written upon is formed directly from the plate h by cutting or stamping its front and sides out of the body thereof, the rear portion of the clip h remaining attached to the plate h. One or more of these clips may be used, although I prefer the use of a single clip 72/, as shown in the drawings, situated centrally and extending the greater portion of the length of the base-plate h. In most of the drawings the rear portion is shown as bent over to form a fold 7L2, which may be pressed down upon the clip h and paper W introduced thereunder, as shown. This plate It is preferably formed with rearwardly-projecting tongues 25 for engagement with and between the copy-sheets b b in proximity to the line of binding, as Z), in the case of copying book or pad B, as shown in Fig. 10. These projecting tongues i may be formed in one piece with the blank A, as indicated in Fig. 1, and then folded over and secured in position, or they may be separately formed and attached to the under side of the plate h, as may be found most expedient.

In use when a fresh carbon-sheet is desired the protection-sheetp is pulled 0%, as indicated in Fig. 8, one edge of a sheet of writing-paper W inserted under the clip 72 and the holder forced between the copy-sheets at the binding end, those sheets b above being folded over out of the way to leave the Writing-sheets unobstructed. The act of forcing the holder between the sheets I) forces the clip it down against the edge of the paper W, so that the latter is pinched and the sheet held against displacement, The Withdrawal of the holder releases the sheet w.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. As an article of manufacture a copying device consisting of a strip of stiff material having a paper-retaining clip formed integral therewith by cutting the body of the strip, a coupling-strip of flexible material attached to said strip of stiif material, a sheet of carbonpaper fastenedat one of its ends to said flexible cou pling-strip, and a protecting-sheet also fastened at one of its ends to said flexible coupling-strip substantially in the manner and for'the purpose described.

2. As an article of manufacture a copying device consisting of a strip of stiif material having a paper-retaining clip formed integral therewith by cutting the body of the strip, a sheet of carbon-paper connected at one of its ends to said strip of stiff material and a protecting-sheet also connected at one of its ends to said strip of stiff material above the connected edge of the carbon-sheet for the purpose and substantially in the mannerset forth.

3. As an article of manufacture a copying device consisting of a strip of stiff material" having a papenretaining clip formed integral therewith by cutting the body of the strip, said strip of stiffening material being also formed with rearwardly-projecting tongues for insertion between the sheets of a book or pad as set forth, in combination with a sheet of carbon-paper fastened at one of its ends to said strip of stiff material, as and for the purpose described.
