LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Feb. with Application filed July 29, 1909. Serial No. 510,275.

110 all whom it may concern:

B0 it. known that I, lAlS'tl-Ilt l5. h'inmnn, n oitjizenot, the United States, residing in the city of New York, borough of Manhat- Ncw York. have: invented a certain new and useful \JHJPIOYCHKIW- in Loose-Leaf Binders, of -l lch the following is a specification.

The invention relates to that class of binders 1n which theniotched leaves are A teccivgcdon posts and held between bars attached to the latter. and the object, of the invention isto provide a binder in which the bars may he separated for the introducio' tio n or reinoval ot'lea Yes without detaching,

.the parts, and in which the. posts may be .lepgthencd or shortened to accommodate a greater or less number of leaves as required.

flAnothrr important object is to provide 2i n'reans .for insuring against. accidental separation of the parts, and for compressing ffand holding the leaves.

" .The accompanying; drawings form a part of this specification and show an approved i v, t t n 2F i0 1 n of the mechanism employed, with the "leayes'and melosmg covers omitted.

Figurel is an elevation showing the posts, hars; and compressor condihoned for service. Fig. 2 IS a planvicw of the top-bar.

li fl ilfltis is a horizontal section through the on the line 3-3 in Fig. 1, showing the compressor in plan view. partly in horijzontal section. Fig. 4 is a vertieal'section, fp'artly in elevation, showing one-0f the jl gposts, and portions of the top-bar and hottoin-bar. in the locked condition. Fig. 5 is a similar view showing the same parts in the open or expanded condition. Fig. 6 is a transverse section through the top-har.

will" 7 is a top View of one. of the postsl gimilar letters of reference indicate the same parts in all the figures. r

The bottonrhar A is shown as ti strip of metal of suitable thickness having sockets A screw-threaded internally to receive the correspondingly threaded lower ends of the posts which are. thus secured to the lower bar. a The posts 13 are short rods sored-threaded to matchto the sockets A or, as',sh0\vn. to'

match to similar screw-threaded ,axial holes in extension sections B of larger'(' ameter than the rods B and having nipples B received in the sockets or another extension section, by thus joining several extension sections together and to the lower lmr A the posts may lie lrent'z'tliened as found herrssary. Each post it is ltttltiFt'tl hp :1 tulle oi sleeve tthe same external diameter as the extension 15. hariue; its lower eel-4e curled inwardly to l'orin an internal thing U closet encircling the. hotly t tho post. M: the upper ends the sit-Pres are threaded and received in rorrespontllug hides llitlod and tapped in the lower plate 1) of the tophar. The upper plate I) is of sheet metal rolled in channel form and is held to the lower plate by stud-rivets l). thus ru-ovhh ing a space in which is located a lu king slide 1*) moved longitudinally h a screw ti having a squared end E tor the reception of a corresponding key. not shown. hr which the screw is turned in its am) not I)".

On the upper end of ea h post ll is a flared head It of a diameter at the top to match the interior of the sleeve t to permit the post to move telescopically therein while prevented from complete withdrawal lvv the engagement of the head with the llanee U. and the flat upper face ot'the head is drilled axially as at b to receive a spur h riveted to the interior of the upper plate l of the top-bar.

\Vhen the top and bottom-bars are forced toward each other to the limit permitted hy the. posts B the latter are anchored to the upper plate by the engagement of the. spurs F with the recesses 71 and the lateral strains due to the thrust of the slotted locking-slide R against. the heads are thus strongly resisted.

By reason of the flared or coniealtorm of the heads the posts are etlectually held against withdrawal when engaged by the lOPlUn J-Slttlt and accidental release is thus prevented while the reinforcement afforded by the spurs permits the locking-slide to he very iirmly thrust against the heads without danger of distortion or other injury.

G is acompressonbar through which the posts extend. composed of two plates or sections separated by studrivets G and containing a locking-plate H operated by a screw G in a fixed nnt- Gfl'similar to the locking-slide E above described. The function of the compressorbar is to hold the leaves beneath it in close contact with the bottom-bar and each other when the number is less than sufiicient to fill the space between thetop and bottom-bars. The comother forms of locking devices scopically in said sleeve,

pressor-bar is notched on one edge, as at g, to permit its application to and removal from the osts, and the locking-plate is similarly note ed, as at h, for the same purpose.

The notches g are preferably inclined or angular the better to resist direct strains and the notches h are each similarly inclined and formed with an offset partially encircling the post when adjacent thereto, thus permitting the compressor-bar to be raised or lowered on the posts by slackening the grip of the locking-plate H thereon while still maininsure against complete removal; the com pressor-bar may hefreed for such removal when desired by turning back the screw Gr far enough to allow thestraight sides of the notches It to coincide with those of the notches g, thus affording sufficient space for the assage of the posts as the compressorbar 18 drawn'away in an angular direction.

Modificationsina be' made in the forms i and proportions without do darting fromthe invention, and parts may e used without the whole. Other forms of compressor-bars may be substituted for the bar shown, and may be used in place of the locking-slide and lockingplate illustrated and described.
