Hamlin, Syracuse, N. Y., assignor to Mc Millan Book Company, Syracuse, N. Y., a cor poration of New York Application September 30, 1935, Serial No. 42,763 2 Claims. My invention relates to loose leaf binders and more particularly to loose leaf binders of the post clamp type. An object of my invention is the provision of 5 a loose leaf binder of the post clamp type in which one cover section, including the casing for housing the post clamping mechanism, may be readily removed from the binder to enable re moval, ire-arrangement or replacement of sheets 10 of paper in the binder and the provision of means whereby the binder may be re-assembled quick ly and with a minimum of elfort by placing the casing over the ends of the posts and pressing thereupon to secure the casing to the posts. A further object of my invention is the provi 15 sion of a loose leaf binder of the post clamp type which is easy to operate, and in which the clamps, for securing the binder covering to the posts, are brought into holding engagement with the posts during re-assembly of the binder by merely pressing upon the casing which encloses the post clamps. My invention further contemplates the provi sion of a loose leaf binder of the post clamp type in which the post clamps are spring actu ated so that they may be secured to they posts merely by pressing upon the housing which en closes the post clamp and the provision of means operated from the ends of the casing for releas~ 3O ing the post clamps from the posts. Other objects and advantages of my inven tion will be more apparent from the following description when taken in connection with the accompanying drawings, in which: 35 Figure 1 is a perspective view showing a com plete binder with the pages thereof in assembled condition. ’ ' Figure 2 is a view taken on the line 2—2 of 40 Figure 1' in the direction indicated by the arrow. Figure 3 is a View taken on the line 3--3 of Figure 2 in the direction indicated by the arrow. Figure 4 is a plan view of the casing with the top portion thereof removed, taken approximate 4 ly on the line 4—4 of Figure 2. Figure 5 is a view taken on line 5-5 of Fig ure 4. Figure 6 is a perspective view of a saddle or fulcrum for the post clamps. 50 Figure 7 is a view showing a spring suitable for pressing the post clamps into clamping engage ment with the posts. ' Figure 8 is a view similar to Figure 2, showing a modi?ed form of the construction illustrated 55 in Figures 1 to' '7 inclusive. (Cl. 129—12) Figure 9 is a view taken on the line 9-9 of _ Figure 8. Figure 10 is a view taken on the line Ill-I0 of Figure 9. The loose leaf binder, in which my invention is embodied, comprises a pair of covers II and I2 between which a quantity of paper I3, pam phlets or similar articles are adapted to be found. Each of the covers is provided with hinge lugs I4 which are adapted to co-operate with similar 0 hinge lugs I6 extending from casings I1 and. I8. Suit-able pintles I9, extending through the hinge lugs Ill and I6, enable the covers II and I2 to hinge with respect to casings I1 and I8 re spectively. 15 The lower casing I'l, while it may consist of a ?at bar to which the posts 2I and 22 for re taining the paper are anchored, preferably com prises a tubular body 20 formed of sheet metal, the ends of which. are closed by metal end clo sures 23. The posts 2| and 22, while they may be permanently anchored in the casing H, are preferably removably threaded in anchor lugs 24 which are secured in the casing as by riveting the ends thereof as indicated in the drawings at 26. The posts 2| and 22 are preferably made in two sections, as indicated at 21, so that the top‘ half of each of the posts may be removed, if desired, and a longer section of post threaded into the lower half of the post in order to ac commodate a larger quantity of paper in the binder. Suitable apertures 28 and 29 are pro vided in each of the post sections for the insertion of a tool to enable the post sections to be readily unthreaded from each other or from the anchor 35 lugs 24. The upper casing I8 is formed in similar man ner to the lower casing I1 and houses releasable post clamping mechanism which upon release en ables removal of the casing I8 together with the cover I2 from the posts whereby sheets of paper may be inserted or removed from the binder. The housing I8 is provided with aligned openings 25 and 25’ for the reception of the ends of the posts which, when the binder is in assembled con-- 1. dition, project through the casing. The mecha nism for releasably securing the casing I8 to the posts 2I and 22 comprises post clamps 3| and 32 together with suitable mechanism for normally urging the post clamps into clamping engage- ' ment with the posts and mechanism for shift ing the post clamps from said position of en gagement when it is desired to remove the casing I8 and cover [2 from the posts. The post clamps 3| and 32 each consists ofa 55 2 2,125,048 by a metallic end closure 62 while the other end of the casing I8 is closed by two metallic end closure members 63 and 64. The end clo gripping section of each of the post clamps is sure member 64, shown most clearly in Fig provided with an opening 31 for the reception ‘ ure 5, is anchored in position by making the portion 66 thereof slightly larger than the casing, of the posts. The opening 31 in each of the gripping sections is slightly larger in diameter as indicated at 61, so that it bears against the than the diameter of the post and is preferably end of the casing. The end’ closure member 64 has an internal hollow portion 68 adapted slightly oval with the long axis thereof extend to receive a spring 69 one end of which is se 10 10 ing crosswise of the housing |8 so that the post, when the gripping section of the post clamp-ris cured to the leg 51 of the slide while the other perpendicular thereto, may freely pass ‘through end is secured to an anchor pin 1| retained in the opening. The openings 31, when the grip—' the end closure 64. The end closure 63 consti ping sections of the post clamps are perpendicular tutes a ?nger piece for moving the slide_52 to one leg 58 of which it is secured by riveting as 15 15 to the posts, are in registry'with the openings shown at 12. The’ ?nger piece 63 is slidable in 25 and 25’ in the bottom and top walls of the the casing and slidable with respect to the end housing I8. Each of the post clamps is pro closure 64. vided, at or near its midpoint, with a trans The mechanism described constitutes a sim verse slot 4| adapted to receive the- midpart 42 of an upstanding member 45 formed as part ple means for releasing the post clamps from 20 comparatively thin metal plate bent at approxi mately its midpoint as indicated at 33 to form gripping section 34 and a lever section 36; The of a post clamp saddle 43. The post cla‘m'p'saddle 43 comprises the upstanding member 45 which is formed with’ grooves 44 and fulcrum points '46 upon which the post clamp rocks. The other end of‘ the post clamp saddle'has an upstanding por tion 41 which is adapted’v to be received in an end slot 48‘ formed- inrthe post‘ clamp. A U shaped hairpin spring 49', shown in Figure '7, rests in the grooves 44 and has its legs extending through‘ apertures 5| formed in the base of the post clamp saddle. 7 When the post clamp saddle and the post clamp are’ in assembled relationship, the legs of the spring 49 rest upon the base of the sad dle and the upper portion of the spring which encircles‘ the upstanding portion 41 presses up wardly upon the lever section 36 of the post clamp thereby rocking the post clamp about the f‘ulcrumpoints 46 so that the walls of the open 40 ing 31 in the post clamp engage the sides of the post. The post clamp saddles may be held in the. casing l8 by striking up portions 50 of the housing. to retain the post clamp saddles against movement longitudinally of the housing and; con 45 ?ne them rigidly between the bottom and top walls of the casing. It will be appreciated that rocking of the post clamps on the fulcrum points 46 will raise‘or lower the gripping sections 34 of the-post clamps so as to release or engage the post clamps with the posts. Means are provided for raising the gripping sections 34 of the post clamps to a position per pendicular to the posts and thereby release the housing from the posts. Such means comprise a slide 52, suitably mounted in the housing l8, and adapted to move longitudinally thereof’ so as to‘ bring cam portions 53 formed in" the slide into engagement with the ends of the gripping sections of the post clamps; The cam portions 53 when movedv into engagement with the ends of the post clamps cam the gripping sections upwardly to a position perpendicular to‘the posts and thus release the posts; The opposite ends of the slide 52 are provided with openings 56‘form ing legs 51‘, 58, 59’ and 6| which straddle the posts, the cam portions-H53 of the slide being formed in these leg portions‘ of the slide, The central‘ portion of the slide has a raised por tion as indicated at 60 which engages the top 70 wall of the casing and retains the slide in the return automatically into a position such that when the binder is to be reassembled the eas ing may be pressed down over the posts and the post‘ clamps re-engaged with the posts without 25 the necessity of returning the slide to its nor mal position manually. When the ?nger piece 63 for releasing the slide is pushed inwardly the slide 52 is moved longitudinally of the casing |8 until’ the cam portions 53 engage the ends of the post'clamps 3| and 32 raising them against the tension of the springs 49 until the openings 31 are in registry with and the side walls of the openings free from the posts whereupon the cas ing I8, together with the cover l2, may be lifted from the ends of the posts. Upon release of the ?nger piece 63‘ from manual contact the spring 68 automatically draws the slide to the left, as viewed in the drawings; until the cam portions 53 are out of engagement with‘ the post 40 clamps 3| and 32, whereupon the springs 49 will automatically press the post clamps back into position to be engaged by the posts. ' When the binder is being re-assembled the housing I8' is placed over the ends of the posts 45 with the openings 25 therein in registry with the posts and upon a slight manual pressure being exerted on the top of the housing |8 the posts will cam the post clamps 3| and 32 up wardly so that the posts will enter the openings 50 in the post clamps and then pass upwardly through the openings 25' in the housing I8. As soon as the posts have passed through the open ings 31 in the post clamps‘ the springs 49 will automatically press the post clamps into en 55 gagement with the posts and upon further move ment of the casing, into the position shown in Figure 2, the housing l8 will be rigidly secured to the posts. ' ' ‘ In Figures 8 to 10 inclusive I have shown a 60 V modi?ed form of the construction illustrated in Figures 1 to' '7 inclusive. In this modi?ed con struction instead of using a single slide in the casing I8, as in the construction previously de 65 scribed, two slides 86 and 81 are used, to the inner ends 88 and 89 of which a spring 9| is secured. The spring 9| tends to move the inner ends 88 and 89 of the slides toward each other thereby moving outwardly the outer ends of the 70 proper position in the casing. A pin 65 extending slides which are secured as indicated at 90 to through the walls of the casing is‘in registry with a slot 65’ formed in the slide and serves to guide ?nger piece 63. Stationary end closure pieces > the‘ slide. 73 theposts and for enabling the post clamps to One open' end of the casing l8r is‘ blocked’ off end closures or ?nger pieces 92, similar to the 93' are also provided which are rigidly held in the casing in a similar manner to that described 75 3 2,125,048 in connection with the preferred form of the invention. In this modi?ed construction the operator presses upon both ?nger pieces 92 to push the slides 86 and 81 inwardly against the tension of the spring 9!. The inward movement of the slide brings the cam portions 53 of the slides into con tact with the post clamps to raise them out of engagement with the posts. When the casing l8 10 has been removed from the posts and the ?nger pieces 92 released the spring 9| automatically returns the slides to normal position. Outward movement of the slides so as to bring the ?nger pieces beyond the end closures 93 is prevented by 15 stops 94 provided respectively on the slides 86 and 81. The stops 94 engage the ends of the post clamp saddles 43 and prevent further outward movement of the slides. When the binder of Figures 8 to 10 is being reassembled the post 20 clamps are automatically engaged with the posts when the housing I8 is pressed down over the posts. It is believed that the operation of the construc tions shown is sufficiently clear from the fore 25 going description and it will be apparent there from that I have provided a loose leaf binder of the post clamp type in which one cover and its associated casing can be readily removed from the posts and when the binder is being reassem 30 bled, after the insertion or removal of sheets of means in the releasable housing adapted to move the post clamps to a substantially perpendicular position with respect to the posts is normally re tained out of engagement with the post clamps by spring means, characterized by a ?nger piece connected to said slide and protruding from one end of the releasable housing, said ?nger piece being movable at least part way into said housing against the action of the spring means to move the slide to post clamp disengaging position, a 10 closure member for the end of said releasable housing through which the ?nger piece protrudes, said member projecting beyond the housing along the rear edge of the ?nger piece, whereby said member protects the ?nger piece from being ac 15 eidentally operated, said construction enabling the operator to remove the releasable housing from the posts by grasping said releasable hous ing at its ends and pushing inward on the ?nger piece while simultaneously lifting the releasable 20 housing upward. 2. A loose leaf binder of the so-called post clamp type wherein the paper is tightly retained between a housing having posts rigidly secured thereto and a second housing releasably secured 25 to said posts, and wherein apertured post clamps are normally spring pressed into angular rela tionship with the posts to clamp the same thereto and wherein slide means in the releasable hous ing adapted to move the post clamps to a sub 30 tions illustrated without departing from the spirit stantially perpendicular position with respect to the posts is normally retained out of engagement with the post clamps by spring means, charac terized by ?nger operated means connected to said slide means and protruding from at least 35 one end of the releasable housing, said ?nger operated means being movable inward at least part way into- said housing against the action of of myinvention, as de?ned in the appended said spring means to move said slide means to paper, the housing may be quickly and conven iently secured to the posts merely by placing the openings in the housing in registry with the posts and pressing downwardly on the‘ top of the hous It will also be appreciated that various modi?cations and changes may be made in the form~ and relation of the parts of the construc 35 ing. 40 claims: 1. A loose leaf binder of the so-called post clamp type wherein the paper is tightly retained between a housing having posts rigidly secured thereto and a second housing releasably secured 45 to said posts, and wherein apertured post clamps in the releasable housing are normally spring pressed into angular relationship with the posts to clamp the same thereto, and wherein slide post clamp disengaging position, means in con 110 nection with the housing for protecting said ?nger operated means against accidental operation, said construction enabling the operator to remove the releasable housing from the posts by grasping said releasable housing at its ends and pushing v2. 1. inward on said ?nger operated means while simul taneously lifting the releasable housing upward.
