Abstract

152,807. Cartwright, J. T. Aug. 5, 1919. Post files; locks and fastenings.-In a looseleaf binder of the type in which the filing-posts fixed to the bottom bar are provided with a T- shaped head engaged by a turn-button on the top bar, the button is attached to a lever, on which means are provided to hold the lever in the closed position. Fig. 3 shows the parts open, and Fig. 6 shows the parts closed. The top plate c is hinged to the upright portion b of the bottom plate a, and is formed with a number of openings, corresponding to the number of filing-posts, each of which is provided with flanged rings e, g to act as bearings for the hollow hub f<1> of a lever f. Diametrically opposite projections on the hub f<1> are turned in to form an interrupted flange f<2> which engages with the projections of the T-shaped top d' of the post d. A stud h on the lever is adapted to snap into the recess i in the plate c to hold the lever, which is made of springy material, in closed position, or alternative methods may be provided. The levers may be connected together so that all may be operated simultaneously. The locking-means may be in the form of a bayonetjoint.
