Application filed July 7, 1905. Serial No. 268.662.

v Tol all whom it mayy concern:

Be it known that I, FREDERICK A. CLEVE- LAND, a citizen of the Unitedv States, and a resident ojfI N ewYork, inthecounty of New Yorl'-and State of New York, have invented certain new vand usefulv Improvements in Binders, ofwhich the following is a specification.

Thisi invention `relates to a device which may -bel appliedl toV ibinders of the loose-leaf type, theobject being to. rovide a device of.v

simple-construction -whic 4may be .use d in connection zwithcoversfor binders of this class, whichnmaytbe easily operated, and whichwill bepositive in its action.

The `user of binders of this description is welliunder'stooda'nd it is notI thought necessaryqtoenter intoan explanation of their operation further than to'state the principal requirement, which is .that any number of pages or leaves ymay-be inserted, replaced, or taken outwithout disturbingv .the .remaining leaves.

.The object of my invention is` to provide a f clamping-sectionfwhich may be attached totheycovers ofthe binder. These clampingsections are normally held apart by the action of springs contained intelescoping members attached `to. said:clamping-sections in the usual manner. Attached to one of these clamping-sections, preferably; ythe upper, I

:provide a post which carries a pawl or dog which is adapted to engage projections on the interior/of va coperating postV or casing which is .secured to the lower clamping-section. i `Thislatter post or casing isadapted to telescopeover the post carrying the pawl or dog. The construction of these parts is suchxthatwhen theclamping-sections are in the )position shown in the drawings a free inward .movement is permitted and the pawl or dogwilloperate to prevent an outward movement ofthe members. -As the position of the covers is reversed, the pawlor dog will drop out of engagement with the outer casing into an inoperative position, allowing the clampingmembers to be lseparated by the action of .the-springs heretofore referred tov or. by other suitable means.

vThe construction and Ioperation of the-:de-

vice will be more fully explained inconnection with' the drawings accompanying-this specification.

v Figure l isfa perspective side elevation of a :pair of clamping-sectionsvor :binder-frames with the4 covers and` leaves.` ofwthebook omitted. Fig. 2 isan enlarged side elevation in section of-the post and casing carrying; the locking mechanism-1. Fig. 3 isrianf-enlarged side elevation andi-detailview showing-the end-view of the pawl or dog in position at the.

lower end of the post carrying .the same as in` Fig.. 2. Fig, 4 isfan enlarged side elevation in section of `thepostiand casing,-,showing al modification of the locking mechanism. v iFig.

5 is anenlarged side lview of; the lower end of"4 the post carrying thepawl or dogishown in Fig. 4.

In Fig. `l at l and 2 is shownanupperand lower yclamping-section, respectively, lwhich may` be attached yby"any'suitabletmeansi to:v

the covers of the binder, or, if;=preferred,\.the coversl themselves .may form the clampingsections and have the lockingfdevice attached directly thereto.

At 3 3 are shown telescoping-members cone.

taining springs which operatenormallyto separate the clamping-sections .land 2.

lAt 4 is shown a ypost which-maybe attached to the upper clamping-section 'tt-,by

any suitable means .and preferably in! such afi ymanner that it may be rotated .thereini This `may be accomplished by socketing` the .upper end ofthepost in the clampingmember 1,-. as shown, and ,holding the same in positionby means of an ordinary flat-head screw. "This screw may be secured in Ithe post 4.byyany suitable means, and by usingflan. `ordinary screw-driver in. the slot thereof; the post ,may

be readily rotated inits. socket.

- At the lower end ofl the poste maybeprovided a slot in which a sliding pawl,.such as 5, as shown in the construction*illustrated` by Fig. 2, is carried. Thispawlhas an opening or slot therein, such as 5, which is ofsuch a shape and. size as=to permit -a limited movement of the'pawl 5 on either side of theretaining-pins 6.and 6.

The -lower end of the slot inzthe post 4 is provided with a beveled surface.v or wallv 7,

upon which thepawl 5 is operated. byngravity.

into or out of engagement with the inner surface of the casing 8. The pawl 5 is lnot at- IOO . a length to permit sufficient movement of the y pawl, so that `the projections from the outer tached or iXed in position in the slot in the post 4, but is retained therein and limited in its movement by means of the pins 6 land 6. The outeredge of the pawl 5 is provided with one or more projections which are adapted to engage corresponding projections on the interior of the casing 8 when the members stand in the position shown in the drawings.

When the positionof the covers and attached parts is reversed, the pawl 5 will drop back by gravity out o f engagement with the casing 8 and allow the partsnto be separated, as already described." y

The casing 8 may be secured to the lower clamping member 2 by any suitableI means, such as by threading the same therein, as shown, or otherwise.

Referring to Figs. 4 and 5, a pawl 9 of someiv what different construction is shown.

The recess in the lower end of the post 4 has the inner surface thereof, against which the pawl 9 rests, formed at slight angle with the center .line ofthe post 4 and is also curved outwardly, so -as to throw the pawl into engage ment with the projections on the inner surface of the casing 8 when the parts stand in the position shown inthe drawings, in which position gravity operates to move the pawl to the Vlower end of the recess;

When the position of the covers is reversed, the pawl 9 will drop to the opposite end of the recess, which is beveled in such a manner that the pawl which is beveled correspondingly is moved inwardly and out of engagement with the casing, so permitting the members to be separated.

A pin 10 projects from the post 4 into a slot 11 in the pawl 9. This slot is so formed as todimit the movement of the pawl 9 and prevent the same from binding or wedging between the post and casing, but is of such surface thereof engage' the projections on the interior of the casing 8. In this position the covers may be pressed together and will be held by the action of the pawl, as described.

The projections or serrations on the interior of the casing are preferably in the form of a screw-thread or spiral, and the projections on the surface of the pawl are made correspondingly. The object of this is to permit of a further tightening of the covers after the same have been pressed down upon the leaves. This may be eifected by rotating the post carrying the pawl by the use of a screw-driver in the slot of the screw at the upper end of the said post, or a lrnurled head `may be provided to allow the same to be turned by hand or by other suitable means.

It will be noted that the device herein shown and described as an illustration of an operative embodiment of my invention is composed of a very small number of parts and that such parts are of a simple construction and may be easily and. cheaply manufactured. It will also be noted that the device when assembled is very compact inform and that the operating parts are self-contained within the same. I do not confine myself, however, to the exact details of construction shown and described, as it will be evident that various modifications and changes may be made therein to adapt the device to vits several uses without departing from 'the'scope ofv my invention.
