Q ATTORNEY ' 2,120.,t4t Patented June 14, 1938 UNITED STAES 'ATENT QFFE ' 2,120,648 ’ LOOSE LEAF BINDER Rubin Rosen, Brooklyn, N. Y. Application July 30, 1936, Serial No. 93,345 (Cl. 129-13) The invention relates to loose-leaf binders and threaded aperture in the leaf-engaging member 2 Claims. more particularly to binders of the post type. With‘binders of this type now in common use the posts are secured to one of the leaf-engaging 5 members and the other leaf-engaging member is locked to the posts by a more or less compli cated mechanism involving the use of a key to ‘release the movable leaf-engaging member for the insertion or removal of sheets from the book. 10 It thus becomes a time consuming operation to ‘remove or insert sheets and should the key be come lost or misplaced it is impossible for the book to function for the purpose for which it was designed. 15 The principal object of the present invention is to provide a loose-leaf post binder to overcome the foregoing serious objections. The binder is of extreme simplicity and is therefore economical to manufacture and can be operated with the 20 greatest of ease when it is desired to remove or insert sheets. Other objects and advantages will become ap parent as this speci?cation proceeds. Referring to the drawing forming a part thereof and in 25 which one embodiment of the invention is illus trated. ' Fig. 1 is an end elevation with parts broken out and parts in section, the binder being in its closed position; 30 Fig. 2 is a detail sectional view taken in a plane parallel to that of Fig. 1, on a larger scale and showing the parts in a position they would as sume when inserting or removing sheets; Fig. 3 is a fragmentary detail sectional view 35 taken at right angles to Fig. 2; ‘Figs. 4 and 5 are detail cross sectional views engaging member 20 to its cover 22. This leaf engaging member 20 carries a telescoping sleeve 23. Secured to the upper end of the sleeve 23 by a set-screw 24 is the operating knob 25. The sleeve 23 has a washer or ?ange 26 and the leaf engaging member 20 is con?ned between the ?ange 2G and the knob 25, it being understood that the sleeve may be freely rotated in rela 3D tion to the leaf-engaging member 20. The closed end of the lower part of the sleeve 23 forms what might be termed a nut, see Figs. 5 and 6. The thread 21 of this nut is interrupted by two out out portions 28. These cut out por tions 28 are of substantially the same cross-sec tional area as the tongues l9 formed on the head boss 14 are a loose thread. The telescoping sleeve 23 and the stationary sleeve I3 thus provide a post. While the post has been spoken of heretofore as in the singular it is to be understood that as many of such posts Fig. '7 is a detail perspective view of one of the ' Fig. 8 is a perspective view of an alternate con struction. Referring again to said drawing the reference numeral l0 designates the lower or what might be termed the stationary leaf-engaging member. 55 The movable leaf-engaging member 20 has the 20 customary ?exible portion 2| securing the leaf cover l2 in a conventional manner well known in ber; and ‘ Figs. 4 and 7. the art. Suitably mounted in the leaf-engaging member In is a stationary sleeve 13. As illustrated the sleeve I3 is provided with a threaded boss M on its lower end and this boss engages an interiorly of the lower part of the upper telescoping mem parts. 5O screw l5 are slabbed off or ?attened as indicated at El and threaded or otherwise secured to the upper end of the screw “5 is a head l8. The under side of the head I8 is provided with a boss having its sides slabbed off or ?attened to form lugs or tongues l9 as particularly illustrated in This member H3 is ?exibly connected at II to its Fig. 6 is a fragmentary detail perspective view 4 the only time it is necessary to remove the sleeve E3 is when one desires to insert additional length ening members to accommodate a large number of sheets. A stationary screw I5 is mounted in axial align ment with the sleeve l3. As shown the lower end of this screw is secured in the boss [4 by a pin I6. Obviously the means for securing the screw H5 in position may be widely varied. The sides of the l8. A spring 30 is interposed between the head IB and the top of the sleeve 23. When it is desired to remove the stationary sleeve l3 for purposes heretofore mentioned the openings 28 are brought into engagement with the tongues'l9 and the knob 25 may then be rotated and the threaded boss l4 thus easily re moved from its socket in the leaf-engaging mem ber Iii. In order to insure against unscrewing the head l8 off the end of the screw l5 when the stationary sleeve 1 3 is being removed the threads in the head l8 are what is termed a tight thread and those in the cover In for the reception of the taken on the lines 4-4 and 5—-5 respectively of Fig. 2; 40 ID. Means are provided and will later be de scribed for removing the sleeve I3. Practically 50 as desired may be utilized in a loose-leaf binder. 55 2 In tion and into 2,120,648 use the binder normally occupies the posi of Fig. 1, the spring 30 being compressed the telescoping sleeve 23 being slid down the stationary sleeve l3. Naturally the amount of the compression of the spring and the relation of position between the sleeves will de pend upon the number of sheets in the binder. In the position of Fig. 1 the threaded portions of the stud l5 will be engaging the interrupted 10 threads 2'! of the telescoping sleeve nut. The parts are thus locked in position and it is im possible to remove any sheets from the binder. When it is desired to remove sheets or add sheets the only operation necessary is to turn the 15 knobs 25 approximately 90°. This disengages the interrupted threads 2'! from the threaded por tions of the stud I5 and the spring 30 will in stantly raise the leaf-engaging member 20 to approximately the position of Fig. 2 or higher 20 making the sheets and binding posts readily accessible. After the new sheets have been added or some old sheets removed the leaf-engaging member 20 is pushed downwardly and the knobs 25 are again turned approximately 90° and the 25 parts are all locked in position. The sheets 3| may be notched in the conventional manner as indicated at 32 to permit of their easy removal or insertion. Referring to Fig. 8 the screw [5 is provided with 30 longitudinal stops 35 located diametrically oppo site each other at the junctures of the threaded portions and ?attened faces. When the parts are in the position of Figs. 2 and 5 the leaf~en gaging members as heretofore explained are free 35 to move away from each other and when it is desired to lock the leaf-engaging members the knob 25 is rotated approximately 90°. The stops 35 will prevent further movement of the nut .at the end of the sleeve 23 in relation to the screw I5 and will thus insure against inadvertently turn ing the knob 25 too much and releasing the parts.
