UNITED STATES PATENT OFFICE.

IRA MAOFARLAND, OF NEW YORK, N. Y.

CARBON-*SHEET HOLDER.

SPECIFICATION forming part of Letters Patent No. 645,400, dated March 13, 1900.

Application led May 27, 1899. Serial No. 718,495. (No model.)

Be it known that I, IRA MACFARLAND, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Devices for Oopying Manuscript, of which the following is a speciiication. Y

My invention relates to improvements for manifolding in books whereby a copy of letters, bills, tbc., may be made in a copy-book at the time of writing the original, thus avoiding the use of a copying-press and press-copy book, which latter must be made of leaves of tissue-paper.

By my invention a carbon manifold copy of manuscript writing may be conveniently and expeditiously made in an ordinary blank book of thick paper, and when a sheet of carbon-paper becomes exhausted a new sheet may be applied in the device without difti culty, and in using the device all handling of the carbon-paper with the fingers is avoided and no difficulty arises in properly placing the carbon-sheet and the sheet to receive the original in the book in which the copy is to be made and preserved.

In the accompanying drawings, to which reference is made, and which form a part of this speciiication, Figure 1 is a perspective view which illustrates the application of my invention in a copy-book, the letter-sheet being omitted. Fig. 2 is a plan view of the jaw or holding-strips without the carbon-sheet. Fig. 3 is a transverse section of the same on line X X of Fig. 2. Fig. 4 is a like view with the carbon attached. Figs. 5, 6, and 7 illustrate the method 0f arranging the device with the paper to be written on ready to be forced into the jaw of the book.

In t-he drawings, 2 represents a bound volume or book of thick paper, paper of any suitable quality to adapt it to receive and preserve copies of letters, bills, &c.

3 represents a carbon-sheet, and 4 asheet of letter-paper-an ordinary letter or bill head-t0 receive the original communication or matter to be written thereon with an ordinary pen or pencil. The carbon-sheet is connected at one edge to a plate 5 of metal or other suitable sti and lasting material. This plate 5 is straight at its edges and of proper width to adapt it to be pressed back lirmly into the jaw of the book between any of the leaves thereof, so that the pressure of the leaves at the binding will firmly h old the plate in place. The carbon-sheet is attached to the plate 5 in parallel, and the edges of the plate being straight no attention in using the device need be paid to the carbon-sheet, for the actv of pressing the plate back into place in the jaw of the book perfectly places and alines the carbon-sheet upon the sheet in the book to receive the copy. The length of the plate 5 is slightly more than the width of the sheet bound in the book, and in placing the plate in the jaw the thumbs of the user will be pressed against the outer corners of the plate, while the ends of the for'engers will be held under the plate and against the edges of the book-sheets, so as to act as guides and so that the carbon-sheet will not lap over at either edge of the book.

The carbon-sheet 3 is connected to the plate 5 by a strip 6 of stiff paper, gumrned on one of its surfaces, s0 that by merely moistening the gummed surface it may be applied to the plate 5. The strip 6 is attached to the carbonsheet 3 by a back-fold 7 of the carbon-sheet, to the surface of which adhesive material is applied.

When a carbon-sheet becomes exhausted, torn, 0r worn out, the strip 6 will be torn off along the edge of the plate 5, leaving the remainder on the plate 5, and then afresh carbon-sheet 3, with attached gummed strip 6, will be applied to the plate 5 upon or over the first strip 6 or over that which remains of it, so that the user will not haveany difficulty in sticking the subsequent carbon-sheets in place, as might be the case if he were compelled to stick the subsequent strips to the surface of the metal. Instead of tearing off the strip 6 along the edge of the plate 5, as just described, the carbon-sheet may be removed from the strip 6 at the folded-back edge 7 and another folded back and the mucilaged carbon-sheet applied upon the projecting edge of the strip 6; but more or less difficulty would arise from this latter method owing to the frail nature of the carbon-sheet and owing to the fact that any carbon that might remain IOO being made.

To the upper surface of the plate 5 are se cured clamps 8, any desired number, preferably three, and of any suitable form of construction adapted to receive andhold the edge of the sheet 4 to receive the original writing. In ordinary use it will be more convenient to put the sheet 4 in the clamps before the plate 5 is pressed back into the jaw of the book, so that the single act of pressing the plate back will place both the carbon-sheet and the letter-sheet squarely and properly in the book.

9 representsadevice for opening and closing the clamps S. This device may be of any desired construction. As here shown, itis a wire flattened to form a cam 10, so that by giving it a one-quarter turn it will lift the clamps, as shown in Fig. 6, and by turning it back to its original position will lower the clamp 4upon the paper, as shown in Fig. 7,. The ends of the wire 9 are extended past the ends of the plate 5 to form convenient handles l2 for manipulating the plate and the attached carbon and letter sheets. The folded ends or handles 12 overlap the ends of the plate to give ample grasp for opening the clasps and also to prevent the wire from turning around beyond bounds.

- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`

l. As a new article of manufacture, a bookcopying device, consisting of a narrow, thin and straight strip of metal, a sheet of carbonpaper fastened at one of its ends to said strip of metal, and one or more clamps attached to said strip of metal for holding a letter-sheet upon the non-carbonized surface of said sheet of carbon-paper, substantially as described.

2. As a new article of manufacture, a bookcopying device consisting of a narrow, thin and straight strip of metal, a sheet of carbonpaper fastened at one of its ends to said strip of metal, one or more clamps attached to said strip of metal for holdinga letter-sheet upon the non-carbonized surface of said sheet of carbon-paper, and means applied to said strip of metal and to said clamp or clamps for opening and closing the latter, substantially as described.

3. Asheet of carbon-paper, a strip of stiffening material applied to one edge of said sheet of carbon-paper and adhesive material applied to the surface of said strip of stiftening material which corresponds to the noncarbonized surface of the said sheet of carbon-paper, in combination with a narrow, thin and straight strip of metal, to which the said carbon-sheet is connected bythe said adhesive material applied to said stiffening-strip, substantially as described.

4. The plate 5 having clamps and the means for operating the same at its upper surface, in combination with a strip 6 applied to said plate, and a sheet of carbon-paper 3 applied to said strip 6, substantially as described.
