LOOSEJJEAF BINDER.

To all. trtom ii may concern:

. Be it. known that l. .TAConN Ltnstax, a 4citizen of the Unite'd States, :ttul a resident of Preston, Oneida county, Stateof Idaho, 5 have invented a certain new and Vnset'ul Loose-Leaf Binder, of which the .following is a specification. This invention is a loose leaf binder ent bodying an improvement upon, or au addi-v tion to, the loose leaf hinder fortuin,"`- the subject. matter of a prior patent, No. 921,467, granted May 11. lftfhupon an application of J. Schaub and. J.v X. Larsen, The salient feature of the vpresent invention consists oi' a binder so constructed that none of the leaves can he removed therefrom without employingr a specialvkcy which pct'- mits the operation olI a member. preferably Ta., locking,r slide, whereby one of the covers of the binder is released, whereupon one or a, plurality of leaves may be removed,r and, if desired, replaced by others, the key in the meantime becoming secured to said cover and remaining,r so secured until the said locking slide is manually operated to return it;

to its normal positio j `.More specifically stated. the invention cm- .bodies a binder plate provided with a'keeper for the locking hey :no with a `trrooved.:

member into which a moored locking' key adapted to slide, a lock-casing tired to said` hinder plate and having ,f frooved tlaugcs adapted to receive the grooved locking key, a post-lockintr slide having pintles to en- ,gage with 'the posts and prot idedralso, with shoulders and notches, and lockiutbolts` slidably tilted between the llaug'es and within the lock casing;` so'that they may be actuated by the insertion and withdrawal ol` the l10 key. The bolts are so positioned and operated that` when the ltey is witlulrawu. they ywill en -gage thtl shouldered notched slide to i vpreclude :novena-tit thereof, but when the, key is inserted into thc keeper and into the 35 grooved xneniberand the grooved llangjes ot' the. binder plate and the lock casing, respecti\'el Certain ot' said bolts are withdrawn i from the slide and other ltolts are thrown into en gagrmcnt with the key for the puri0 pose oi' retaining. said key in alockctl position dut-in;r the timethat. the slide is re.- leased trom the posts. rl'his is important for the reason that it indicates to tnebool:

illustrating a parl at' the bindet' plate, the locking mechanism and vcertain parts asso- .ciateo there ith` said locking mechanism bein tr represented in position for locking the post-locking' slide against movement. Fig. 4 isa view similar to Fig. 3 showilngr the keyr in the lockingh mechanism for the purpose of releasing the lockingIf bolts from the, postlockingr iide. and for retaining said key within a keeper otl the binder plate. Fig. 5 is a platt view ot' the post-locking slide removed from the bindt-r. Figs. G and i' are` crosssections ou the lines tft- 6 and 7--7 re- 85 spectively, of l"i Si. ln Figs. 1 and 2 lthe blnder is shown as having covers. A. and posts, B, on which are titt'cd the lea-ves. C. Cover, A', is provided with a plate. (t, on the inner side of J0 said cover. and to this plate is connected one end of a .series ot' posts, li. preferably by means ot pintles, The other cover, A, is shown as being, provided with a binder plate, l). which is secured firmly to the inner ot' said cover. A. said cover having,r a recess,

o'. shown more particularlyy in Fig. 2.

Binder plate. i) .`is shown in Figs. 3, 4, 6 :zml and at one edge said binder plate is provided with c ves. d', which are. separated 100 by interveningn slots. (F. lThe binder plate is provided, furtlurmore, with a longitudinal slot. c. and near oneedg'e of said binder plate it is-depressed. as at a', so as to form a lougittulinal channel` said, channel being 10.5 adapted for the reception of the locking key. whereby the depression and channel operate as a keeper for said locking key.

2 'ovinos F designates a locking slide which is provided on one of its edges with a series of y angle slots, f, and with pintles,l f', see Fig` 5.

Near one end the locking slif e is'provided with rais'cdtransverse flanges, g, kwhich are 'preferably knurled, said flanges being posi- 'tioned for operation in the longitudinal'slot,

e, of the binder plate, whereby the flanges serve the purpose of thumb pieces against which pressure may beapplied by hand for the pur ose of adjusting the slidelengthwise of the inder plate. An edge portion of slide, F, is fitted within the alined eyes, d',

.of the binder'plate, and this edge of the slide, together with pintles, f', areadapted to vmove in said eyes, d whereby the slide is connected to the binder plate, and said slide may bev moved inthe direction ofits length by applying pressure to thumb pieces,

g: Slide, F, 1s ositioned intermediate the inder plate an cover, A, as vshown more particularlvin` Fig. 2, andi-hnsl the slide is concealed from view, except that part thereo which is opposite to slot, of said binder p ate. y f

Locking slide, F, is provided with a flange, Ii, entending lengthwise thereof at one end portion ofthe slide, and on the opposite edge from pintles, f. This flange is produced Von thc slide b increasim1r the width of one' end portion t iereof sotliat the flange lies. in the plane of the slide. and in this tlangel are notches, li', which are separated so as to produce shoulders, h2. .The binder plate, l), isprovided at one end of the keeper, e', with a serrated or cor.

Yrngatcd member, d, see Fig. 1, and into this grooved member is adapted to slide a grooved part, E', of the locking key, E, the; latter lining shown in Fig. 4.

(l designates a lock-casing which is lixed to binder plate, l), in a position close to slot, e, and keeper, c', see Figs. 3, 4, 6 and 7.

This lock-casing is compact in construction.

and attached rigidlyl inv a suitable way 'to lthe binder plate, whereby the locking mech-` anism is brought` into cooperative relation to keeper, c', und to the notched and shouldered part of postl lmking slide, F. The lock-casing is providt-d iuteriorly thereof with flanges, g', which are parallel to'cnch other so as to provide intermediate spaces for the reception ot bolts, H, II', and.' I', said flanges .serving the purpose of guides for the sliding bolts. The flanges extendf .bci-oss the path of the key when the lat-ter.

mgved within keeper, e', so astok bcilin` serted ,into the lock-ea`siug, and in said end portins` the flanges :ne provided grooves, g2, adapted. to receive the grooved part, El', of the keyJ 'r'llie grooved parts, (fi, ot" t-lie flanfres and ilie--grooved member, Il, of the4 biu'dizr plate preclude the insertionof an Bolts, vH, H', are provided with teeth, i, and with these teeth mesh the teeth of a gear wheel, J', the latter being fitted loosely on a stud or journal, j, projecting from one of the flanges, g. The bolts, l, I', of the other pair areprovided with gear teeth, z', which mesh with the teeth of a gear, J', loosely mounted on a stud or journal, j', of another of the flanges, g', see Figs. a and 4. The gear, J, thus operatively connects bolts, H, H', for simultaneous movement in opposite directions, and similarly the other gear, J',

connects bolts, I, I', to insure simultaneous movement in opposite directions to said: bolts, I I. Each bolt is provided at one end with a bevel, k., adapted to enter a notch, li', of the post locking slide, F, whereby the fieY slide is adapted to be securely locked in poof said bolts, Il', I. It will thus be seen that one spring acts to iinpei bolt, H', in

one direction. and this bolt acts on rear, J, to move theeoinpanion bolt, H, of t iepair into engagement with a shoulder of locking slide, F. lIn a similar manner the other spring, L, acts' on bolt, I, which turns gear, J', for the purpose of moving the companion bolt, I', of the pair, I, I', so that the bolt, I',.

will enter a, notch of slide, F, the bolts, H,r

l', acting to lock the slidein an operative position.

Tlie bolts, rvH', I, are provided with rounded ends, ne, said rounded ends of the bolts being o )positie to the groovcd parts, g,
