Definitions

  • This invention relates to book constructions, particularly those of the blank book type in which a plurality of sheets of paper are loosely bound together as, for example, in memorandum books, vadvertising pamphlets, printed books, note books of the type commonly used by stenographers, etc.
  • Fig. 2 is a top plan view of a book after the sheets thereof have been straightened and a spiral bind ⁇ ing wire threaded through the series of binding holes to bind the sheets together;
  • Fig. 3 is an enlarged detailed View in sectionshowing the manas in ordinary books but a prominent convex edge which usually has a ragged appearance due to the fact that the holes in the sheets are generally larger than the binding rings which extend therethrough. This convex edge is not only unsightly but makes it diilicult to ilip over the pages of the book to find a particular page,.
  • Fig. 4 is a sectional view taken along the line 4--4 of Fig. 3;
  • Fig. 5 is a side elevation of the top Vportion of a finished book illustrating the arrangement of the binding wire and holes through which such Wire is threaded;
  • Fig. 6 is a partial end view of the top of the book illustrated in Fig. 5;
  • Fig. 7 is a View similar to Fig.
  • Fig. 8 is a top plan view of a portion of the upper end of a book of sheets after drilling the binding holes in accordance with the operation illustrated in Fig. 7;
  • Fig. 9 is a broken side elevation of a finished book made in accordance with the methodv shown in Fig. 7 and illustrating the arrangement of the sheets when the spiral binder is inserted in place;
  • Fig. 10 is a top planview of a portion Aof the' upper end of a book of sheets having holes drilled in a slightly different manner from that illustrated in Figs. 5 and 8;
  • Fig. 11 is a side velevation of the portion of the book illustrated in Fig. 10;
  • Fig. 12 is a View similar to Fig. 10 showing the binder in place and
  • Fig. 13 is a side elevational view of the portion of the book shown in Fig. 12.
  • the numeral I designates a stack of sheets of similar size, contained between two outer sheets 2V ⁇ which may be made of heavier paper than the sheets I which constitute the book.
  • the sheets 2 may be of substantially the same size as the sheets l, as shown in Figs. 1 and 2 of the drawings, so that they :form coversy for the latter and maybe integrally joined together as is common with note books, blank books, etc. in which the cover is made from a single piece of sheet material of sufficient size to form top and bottom cover portions for the book of sheets and an intermediate portion for covering the bound edges of the sheets.
  • 'Ihe closely related holes 3 are relatively sma in diameter being from .0185 of an inchtoz67 of an inch in diameter when ⁇ using a spiral binder.V whose convolutions are rcloselyrelatedand areV of minimum size in order to minimize the bulki- 2,279,193 j, n A
  • each sheet are arranged in a row which is disposed in substantial parallelism with the adjacent or binding edge of the sheet.
  • the rows of perforations in the sheets are variably spaced from the binding edges ofthe sheets so that a line extending through the centers of a setof successive perforations in the superimposed sheets will be bent from ⁇ the straight.
  • the row of perforations in each successivel sheet, starting from the top sheet is positioned a distance slightly farther from the bindingedge of the sheet than the ⁇ overlying sheet until the center of ⁇ the book is reached.
  • successive rows of perforations of the underlying sheets from the center of the book are graduated so that the distance of each successive row from the binding edge thereof is less than that of the overlying sheet.
  • This arrangement of the rows of perforations is more clearly illustrated in Fig. 5 of the drawings, the rows of perforationsl being preferably graduated so that a set of successive perforations will be a curved area whose arc of curvature is practically the same as the arc'of' curvature of the portion of the helical binder which extends through such set in the closed condition of the book.
  • the rows of holes 3 in the book illustrated in Figs.v 1 to 6 are not only variably spaced from the binding edges of the sheets but are also arranged so that successive perforations in the sheets areY variably spaced from Aa side edge ⁇ of the book.
  • Fig. 6 which shows the sets of successive perforations of all the rows graduated vso that each set of successive perforations, startingy from the top set, inclining towards the left hand side edge of the book, ⁇ as viewed in such gure.
  • the incline in this case is similar to the degree of offset or pitch of the portion of the helical wire which extends through a set of successive perforations in the closed condition of the book.
  • the perforations 3 are arranged in the sheets so that successive perforations in the sheets are curved and offset to the same extent as the portions of the helical wire which extend therethrough.
  • the side edgesof all the sheets constituting the book therefore will be four-square and contained in planes vertical to-the top sheet of the book and will be maintained in such condition bythe helically shaped binder.
  • the unperforated sheets are preferably first arranged so that the side edges thereof are obliquely disposed at the same angle to which the coils of the spiral binder which will bind the sheets t0- gether are offset and the top and bottom edges of the 'sheets are curved to approximately the same degree as the curvature of the coils of such
  • the book of sheets is then held in p0- sition by any suitable means and the rows of holes .then .provided along those edges of the sheets whichv are to constitute the binding edge of the book.
  • a paperr'cutting machine such as is illustrated and described in my copending application Serial No.
  • the ⁇ side .edges 'of the sheets however should be :inclined in the manner previously describedifthe binder is to be of the helical type in order to takecare of the offset ofthe coils thereof.
  • the straight line of the drill will be broken so that the drilled holes 3 form a V-shaped notch whose apex extends in a direction opposite to that of the notch in the guide plate
  • the diameter of the series of holes 3" should preferably be suiiiciently larger than the diameter of the helical binder 4 so that the sheets I and covers 2 will be maintained in the manner heretofore described.
  • the binding member is made from a single piece of wire so that the ring members 5 thereof are parallelly arranged in pairs with the ring members of each pair in spaced relation and each pair of members connected in spaced relation by longitudinally extending portions 6 of the binding wire, as is illustrated in Fig. 12 of the drawings
  • the book of sheets need not be ciset obliquely as in the case of the'books illustrated in Figs. 1, 2, 8 and 9 of the drawings, but need only be either arcuately arranged as is illustrated in Fig. 3 of the drawings or angularly arranged as is illustrated in Fig.
  • a book comprising a plurality of sheets having their binding edges and side edges substantially contained in planes vertical to a plane containing the topmost sheet in the closed condition of the book and having correspondingly spaced perforations along their binding edges and a unitary sheet binder having a length substantially equal to the width of the book and having portions thereof extending through successive perforations in said sheets and loosely securing the sheets to enable individual sheets to be shifted as a whole relative to the other sheets in the book, the perforations of each sheet being arranged in a row disposed in substantial parallelism with its binding edge, the rows of perforations in the sheets being variably spaced from the binding edges of the sheets in a graduated manner and the successive perforations in the sheets being variably spaced from a side edge of the book so that a line extending through the centers of a set of successive perforations will be bent from the straight and offset from a vertical plane containing the side edges of the sheet on one side of the book, the portions of said binder intermediate the outermost sheets of the book being bent
  • a book comprising a plurality of sheets having their binding edges and side edges substantially contained in planes vertical to a plane containing the topmost sheet in the closed condition of the book and provided with correspondingly spaced perforations along their binding edges, a unitary substantially helically shaped sheet binder having a length substantially equal to the width of the book and having portions of its coils extending through successive perforations in the sheets and loosely securing the sheets to enable individual sheets to be shifted as a whole relative to the other sheets in the book, the perforations of each sheet being arranged in a row disposed in substantial parallelism with its binding edge, the rows of perforations in the sheets being variably spaced from the binding edges of the sheets in a graduated manner and the successive perforations in the sheets being variably spaced from a side edge of the book so that successive perforations are arranged in a curved manner when viewed in the direction of the central axis of the helical binder and are obliquely disposed when viewed in a direction transverse
