Class 146(1) A loose leaf binder having two or more arches to pass through spaced apertures in sheets to be bound, has each arch constituted by a flexible tubular member with one end detachably securable to a board of the binder and the other end permanently secured a board of the binder which is formed with an aperture giving access to the bore of the tubular member, and a third aperture is formed in the board between the arches, so that .rigid members may be passed into the tubular members for strength during filing and the third hole used for lacing the sheets permanently together, Flexible tubular members 13, 14, comprising coiled springs, are permanently secured through holes 15, 16 in a back board 10 and support strip 20 and their free ends may be releasably secured over a rigid U-shaped member 17 hinged to a plate 18 on a front board 12 to form arches or secured under lugs 25 on a clamping bar 22. A rigid U-shaped member 26 may be passed through the holes 15, 16 to strengthen the member 13, 14 during filing of papers. A hole 19 between the holes 15, 16 is used for filing sheets permanently on a lace as in Specification 514,465. The boards 10, 12 may be hinged at 11 as shown, or may be flexible and have opposite edges folded over to house suspension rods. The whole device may be secured to the bottom board of a box file, the clamping bar 22 then being replaced by a known double wire clamping bar. According to the Provisional Specifica tion, the U-shaped member 26 may be used as a transfer device, the ends 27, 28 entering into the free ends of members 13, 14 and also may be made into a permanent binder by having screw-threaded ends engaged by nuts.
