March 31, 1959 SHOZO MIYAKAWA CUMULATIVE PAPER FILING DEVICE Filed June 1. 1954 INVENTOR. wiakazz/cz CUMULATIVE PAPER FILING DEVICE Show myakawa, Tokyo-to, Japan Application June 1, 1954, Serial No. 433,704
1 CIairn.-- (Cl. 129-5) This invention refers to a cumulative paper filing device which is applicable for the filing of newspapers,'
pamphlets and slips and leaflets.
The principal object of the invention is to provide a device comprising a base and a pressing bar which are hinged together along the longer side of the bar, and on the base is provided metal filing hooks formed to have an arc concentric with the axis of said hinged line, while the upper part of the pressing bar has a profile conforming to the arc of said filing rods, so that the filing rods penetrate into the inside of the pressing bar through Fig. 1 shows the cross section of the device, in which 1 the solid line shows the pressing bar in its opened position and the dotted line illustrates the pressing bar in its closed position.
Fig. 2 shows the cross section of the device having the papers filed therein and opened.
Fig. 3 shows an end view of the device where a pressing device is attached to the pressing bar, and the dotted line shows the latching device in its opened position.
Fig. 4 shows a perspective view of the device when the pressing bar is opened.
An example of the device as used as a newspaper file is explained below, referring to the drawings. A base 1 and a pressing bar 2 are hinged together along the longer side of the pressing bar 2 by means of rotatable shafts 7 and 8 extending through and journaled on the pedestals 3 and 4 rigidly fixed to the base 1 on one hand and the end 5 of the pressing bar 2 and the bearing 6 affixed to the pressing bar 2. On the base 1 are provided several filing hooks 9, projecting therefrom along the width of the pressing bar 2, and having an arcuate form concentric with the axis of said rotating shafts 7 and 8. The upper surface of the pressing bar 2 has a profile conforming to the curvature of the said filing hooks 9. As the pressing bar 2 rotates, the filing hooks 9 penetrate into the cavities 12 provided in the pressing bar 2 through the holes 11 drilled in the front edge of the pressing bar. When the front edge 10 of the pressing bar reaches at the root of the filing hooks 9, the top points of the filing hooks 9 are designed to stop inside of the pressing lzaar 2 as shown by the dotted line 13 of the pressing bar Fig. 1.
To keep the front edge 10 of the pressing bar biased toward the base in order to hold the filed papers, there will be described a preferred form. A spiral spring 14 (Figs. 3 and 4) is provided on the shaft 8, one end 14a of such spring being affixed to the shaft by securing means 14b and the other end 140 resting in engagement ates Patent with the end of the pressing bar 2. A small lever 15 is afiixed to the rotating shaft 8 extending from the end of the pressing bar 2. When the lever 15 is pressed down to the lowest position against the torsional force of the torsion spring 14, and the latch 16 at the end of the lever 15 is latched to the complementally formed hook 17 afiixed to the base 1 by utilizing the inherent resilience of the lever 15, the front edge 10 of the pressing bar is kept by means of the torsional force of the torsion spring 14 biased toward the base for any amount of filed paper.
To file papers, the small lever 15 is pressed down by the thumb while the base 1 is gripped by the hand, and the latch 16 is disengaged from the hook 17 by pressing the lever 15 sideways a little. Then the lever will be easily turned by the thumb, and as this lever is engaged with the pressing bar 2 at the lug 18, the pressing bar 2 is turned together with the lever 15, so thata gap is produced between the front edge 10 of the pressing bar and the filing hooks 9, as shown in Fig. 1. The pressing bar 2 has formed thereon a gauging groove 2' for gauging the ends of the papers being filed with respect to the filing books 9 to properly punch the papers being filed. When the. lever 15 is turned to the left after having inserted the papers 19 to be filed into this gap and within the gauging groove 2', the papers 19 are pierced through by the filing rods 9 because of the shearing force between the top ends of the filing rods 9 and the holes 11 of the front edge 10 of the pressing bar, and are pressed down to the root of the filing rods 9, being pushed by the front edge 10 of the pressing bar. When the lever 15 is further pressed down to the lowest position and its latch 16 is engaged with the hook 17, the front edge 10 of the pressing bar will hold the papers 20, pressing them toward the base 1, as shown in Figs. 2 and 3.
This invention, including the mechanism as above de' scribed, has the advantages as mentioned below, and is an improvement on the filing devices hitherto used. The advantages are that it serves the purpose of accumulating filing by mere turning of the pressing bar to and fro while holding the papers to be filed by one hand and by the other one end of the base, and as the top points of the filing hooks remain inside of the pressing bar and are not exposed after the papers have been filed, there is no danger in handling as the entrance of the filing hooks into the pressing bar is made at the front edge of the pressing bar, the holding of papers is effected by such a narrow part that the part of paper that may be covered by the pressing bar when filed is at a minimum. Also, the smooth convexed surface of the pressing bar causes the papers that are turned over to bend naturally and prevented from being torn away.
I claim:
A binder for desired sheets comprising an elongated generally fiat barlike base, a first angular bracket mounted on said base near one end thereof and upwardly extending therefrom transverse thereof, a second similar angular bracket mounted on said base longitudinally spaced from said first bracket and upwardly extending therefrom transverse thereof along a line relatively considerably spaced from the other end of said base thus leaving a portion of said base free, such free portion of said base constituting a handle for manipulating said binder, a shaft journalled in said brackets and extending in parallel with said base near one edge thereof and vertically spaced therefrom, a plurality of arcuate pointed prongs mounted on said base and upwardly extending therefrom concentric with the axis of said shaft, an elongated arcuate clamping member extending longitudinally across the space between said brackets and cov 3 operatively connected with said shaft for rotation about the axis thereof, the curvature of the radially outwardly directed face of said arcuate clamping member extending concentric with the axis of said shaft and concentric :with said arcuate prongs, cavities formed in said arcuate clamping member which are respectively aligned with said prongs for respectively receiving said prongs through corresponding openings formed in the forwardly facing shoulder ofsaid clamping member when said clamping member is forwardly rotated into its operated closed clamping position with respect to said base, a torsion spring coiled about said shaft and having one end fixed thereto and having the opposite end thereof in engageaevems c clamping member 'into open position with 'the forward shoulder thereof away from said base for the purpose of ment with the other rearwardly facing shoulder of said clamping member for rotatably biasing said clamping member in the direction of its operated closed clamping position, a lug extending from said clampingmember at the end thereof which is adjacent said second angular bracket, a lever fixedly mounted on said shaft for rotajfiOn therewith adjacent said second angular bracket for engaging said lug upon rearward rotation to rotate said areuate clamping member rearwardly so as to move such permitting insertion of sheet material to be bound in the binder, a first latch member carried by said lever, and a second relatively stationary latch member carried by said base for latching coaction with said first latch member carried by said lever when said lever is rotated forwardly, said torsion spring exerting its force for rotating said clamping member forwardly into its closed operated position when said latch elements are inlatching coaction, the latching coaction of said latch members securing said clamping member in the closed operated position thereof against the torsional force of said spring.
