Application filed March 2, 1917; Serial No. 152,031.
To all whom it may concern Be it known that I, JOHN MURRAY, a subject of the King of Great Britain and Ireland, and a resident of Edinburgh, Scot land, have invented'certain new and useful Improvements in Loose-Leaf Books, of which the following is the specification.
The invention relates to loose-leaf books and binders of the type in which pins secured in the binding cover pass through perforations in the leaves; and the invention has for its object to provide a loose-leaf book in which the various disabilities of existing binders are obviated, in which there are no complex locking devices and in which the insertion and removal of leaves is a matter of the greatest simplicity.
According to the invention the improved binding device comprises essentially a cover the back of which is of sufficiently rigid construction to serve as a guide. Coacting with guiding surfaces on either internal side of this back are rails having projecting pins engaging apertures perforated as usual in the loose leaves of the book, which rails lie on either side of the inner or back edge of the assembled leaves. Stops are provided in the back to limit the travel of the rails with the leaves therein, and a locking or clip device may be provided to retain them in position. Means are provided for retaining the rails at such a distance apart (irrespective of whether there be a full complement of leaves) that they snugly fit the guides in the back. The back may be curved or fiat, and is fitted with a case of cloth or other material after the manner of a book cover.
An example of the carrying out of the invention is shown upon two accompanying sheets of explanatory drawings, Figures 1 and 2, Sheet 1 being respectively an end elevation of the sheet metal back and leaf retaining rails, and an end elevation of an assembled volume, while Fig. 3 shows in end elevation an alternative form of sheet metal back. Figs. 4 and 5, Sheet 2, are respectively a sectional elevation of leaves assembled upon the rails and a vertical sec tional elevation of a completed volume.
According to this simple illustrative ex ample, the back A of sheet metal is ovoid in section, the edges B being inturned to form guides for the rails C which are of substantially semicircular section. A block D filling one end of the back (Fig. 5) closes the guides B and so determines the position of the rails 0 when they are pushed home. At the other end of the back the space behind the guides is filled by a similar block E. Instead of the guide edges B stopping abruptly as shown in F ig. 1, they may be out-turned as shown in Fig. 3 to form grooves in which the usual cover jointing strips are heldthus avoiding any tendency for these strips to be torn off when the book is opened.
On the rails C, and as to be seen most clearly in Fig. i, are pins G passing through the leaf apertures. The outer ends of the pins on one rail butt into recesses H formed in the other rail and thus determine the width between the rails. The covers J are arc mounted upon the back in usual bookbinders fashion, the back being also covered and finished in any desired manner.
Alternatively, the rails with the leaves may be adjusted to fit the guides in the back by the insertion of some form of filling either outside or inside the rails.
In order that the completed book may open flat or substantially so at any part, the pins on the rails may be curved. Or flexible pins, formed for example of closely wound helical coils, may be used. Any convenient form of catch or lock may be provided to prevent withdrawal of the filling from the back.
What I claim is l. A loose-leaf book device comprising a cover the back of which is of sufiiciently rigid contruction to serve as a guide, guiding surfaces on either internal side thereof, rails one on either side of the assembled leaves and coacting with the guiding surfaces, projecting pins on the rails engaging apertures in the loose leaves, and means to limit the travel of the rails in the back and to determine the width between the rails, as set forth.

A loose leaf book device comprising a cover the back of which is of sufiiciently rigid construction to serve as a guide, guiding surfaces on either internal side thereof, rails on either side of the assembled leaves and coacting with the guiding surfaces, projecting pins on the rails engaging apertures in the loose leaves, filler blocks at the oppo- In testimony whereof I have signed my site ends of the back one of said blocks bename to this specification, in the presence of mg larger than the other and extending Into two subscribing W1tnesses.
