G'LAREBT('3E B. DAVIDSO N, OF SAN FRANCISCO, CALIFORNIA.
MANIFOLDING-BOOK AND THE METHOD OF MANIFOLDING.
To all whom it may concern Be it known that I, CLARENCE B. DAVID- soN, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have made a new and useful Invention'to wit, Improvements in Manifolding- Books and the Methods of ldzinifolding; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.
Among the objects of the'invention is to provide a triplicating book that is simple and convenient in operation and that will eliminate any back hand or offset copies on the reverse sides of any. of the record sheets, afterthe original impression has been taken.
Other objects and advantages will appear as this description progresses. I
In this. specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such forms, because it may be embodied inot her forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied. 4
In, the, accompanying one sheet of draw- 1ngs I Figure lis a plane view of a piece of carbon paper forming part of this invention.
, 1 Fig. 2 is a perspective view fromabove of a manifold book constructed in accordance with this invention, with the carbon incorporated therein. and shown ina slightly elevated position before folding into the record sheet below.
In detail the construction illustrated in the drawings comprises a manifold book formed into sections as shown in Fig. 2, each section is composed in the following order: Under thejtop cover,if any, a special carbonsheet coated on its opposite sides on re verse sides of its transverse center and about two thirds the length of the record sheets is so placed that the first carbonized half A faces downward and will be attached to the stub, so that the other half B of the carbon sheet facing upward, will fold over it when in use. Below this carbon 1 are a number of sheets of paper 2, that extend the full length of the book and have perforated lines as shown in 4, 5 and 6. About mid- Specification of LettersPatent.

Application filed October 7, 1918. Serial No. 257,307.
way in the book is placed a heavy flexible paper 3, immediately above another carbon sheet like the first one in the book. The number of legible manifolds possible from a single carbon sheet being known, the pages of the book are proportioned accordingly and the carbons may be distributed throughout the book by interposin them between a given number of pages. he sheet of heavy paper 3 superimposed above each carbon sheet prevents the pencil or pen pressure in maifolding, registering on the sheet below it. This heavy flexible paper 3 is the same length as thrla carbon and is perforated at the stub on y.
The present disclosure is confined to a triplicating book, so bound that it is intended that all three sheets be torn from the stub before a second sheet is operated upon. This is necessitated by the back of the carbon being bound inthe stub. It is obvious however, that by utilizing a loose carbon, not bound in the stub, that the triplicate impressionsmay be left bound to the stub and bent backward while the carbon is inserted above the succeeding full length page, the mode of operation being the same in either instance. The binding in of a multiplicity of carbons with superimposed heavy paper 3 .is of course optional and is not essentially a part of this invention, it being a good expedient in manifolding books containing a number of pages inexcess of the number that a single sheet of carbon will give a good transfer impression upon.
The carbons, the record sheet and the heavy flexible paper sheet are all bound together at the stub 7 by wire staples or other suitable means such as 8 and 9. The perforated line 10 on the stub facilitates the tearing oil of the sheets easily. The sheets are likewise perforated or scored as at 4:,between the division adjacent the stub and the intermediate division, that receives the original writing, and is similarly perforated at 5 between the' intermediate division and the sheet that becomes the duplicate. The second score line or perforation t should fall immediately beneath the division of the carbon between the blank and the carbonized surfaces thereon.
This invention is operated substantially as follows:
The record sheet is folded first along the perforated line 5, thus folding the outer division of the sheet backward and into superimposed position'over the end of the carbon 'portion 13 downward and superimposes the outer section or duplicate immediately above the portion C of thecarbon, which leaves the portion A of the carbon superimposed above the first divisionof the sheet that will become the triplicate. These various divisions are similarly printed or' lined to register when the sheet isfolded up. By this arrangement the carbonizedsurfaceA of; the carbon sheet lies immediately against the page upon which the triplicate impression is to be registered, the uncoated opposite side C'of the carbon protecting the sheet immediately above from any impression such as is made when a double coated or a carbon'sheet coated on both sides is used, and the uncoated portion D. similarly protects the original. By this invention the material dis advantages following the use of a sheet coated on both sides are obviated. First, such a double coated carbon is disagreeable to handle as it smudges the fingersof the operator and likewise the sheets against which it lies. Further duplicate and triplicate having carbon impressions on both sides smudge the others when packed or filed away; or when the stubs are left in thebook and further impressions are taken above them. The present invention gives a clear record on one side of the record sheet only.
The original record is impressed on the inverted middle section of thesheet when folded in the manner described. This record is transferred through the carbon 13 to the end section of the sheet immediately beneath which is the duplicate, being. the first impression under the original. The impression continues on through the carbon sheet A to the first sheet joined to the stub 7,; which becomes the triplicate impression of the original record. When the record is complete the leaf is unfolded to full length, the carbon turned back at the stub and the complete record sheet torn from the stub on the perforation line 6. This'shows the triplicate and the duplicates facing upward on the op posite ends of the sheet, and the original, on the intermediate section of the sheet, facing downward. The sheets may now be separated on the perforated lines 4-.-5 into the three separate divisions forming the orig- W1tnesses inal, the duplicate and the triplicate of the record, to be disposed of as desired.
Having thus described this invention,
what Iclaim and desire to secureby Letters Patent is 1. A manifolding book comprlsing a plurality of record sheets and carbon sheets bound together, each record sheet having two-fold lines and foldable'into end and in- V 'termediate sections, each carbon sheet having a single fold line and two carbon surfaces, the carbon surfaces being placed on opposite faces of the sheet and on opposite sides of the fold line; one of said carbon surfares facing downwardlyon an end section of said record sheet and the other carbon surface" facing away from the intermediate section, whereby the remaining end section may be folded over said last mentioned carbon surface and said last mentioned end section and intermediat section folded over onto the remaining end section, whereby an impression on one side of the intermediate section is made to appear;on the opposite side of the end sections,
2. Amanifolding book comprising a plurality of record sheets and carbon sheets bound together, each record sheet having two fold linesand three record sections; each carbon sh eethaving arsingle fold line and two carbon surfaces, equal in length to two sections of said record sheet, the carbon surfaces being placed on opposite faces of the sheet and on opposite sides of the line of the fold, one carbon surface facing downward over an end portion of the: record sheet and the opposite carbon surface facing upwardly away from the intermediate section of the same record sheet, whereby the remaining end section may befolded over said last mentioned carbon surface, and said end and lntermediate section folded over onto the remainlng end sect1on,whereby' an impression on one side of the intermediate section is made to appear on the opposite side on the end sections. Y
3. A manifold book for executing triplicate records comprising record sheets and carbon sheets bound together, each record sheet having two weakened lines of fold, and three record sections, and each carbonsheet having a single weakened line of fold and two carbon surfaces, the carbon surfaces being placedonopposite faces of the sheet and on opposite sides of the line of fold, in such manner that impressions will be recorded'on the upper; faces of the record sheet only.
In testimony whereof T'aflix' my signature in presence of two witnesses.
