eran r i ROBERT ULARENOE IDUNBAR, OF OTTAWA, CANADA..
rioosnnnar Brianna.
To all whom 5' may concern:
Be itI known that lf, ROBERT CLARENCE DUNBAR, a subject of the lling of Great Britain, and resident of the city of Ottawa, Canada, have invented certain new and useful linproveinents in llooselleaf Binders, of which the following is a specification.
The invention relates to improvements in loose leaf binders, as described in the present specification, and illustrated in the accompanying drawings that form part of the same.
The invention. consists essentially of a flanged backplate formed of an integral piece of sheet metal, and having` a flanged tiltable tongue portion carrying;4 filing posts, and adapted to interlock with the remainingl portion of the bach-plate.
rllhe objects of the invention are to devise a binder :tor filing; letters or other loose leaf documents and papers, which shall be of light and durable construction and most inexpensive with the fewest number of parts possible.
ln the df'awinn's, lligojure l is a perspective view of the binder with several leaves held therein. Fig. 2 is an elevation view of the binder from th-e inside. lil 3 is a inidcross sectional view ot' the binder when opened. Fin'. d is a mid-cross sectional view of the binder when closed.
llilre numerals of reference indicate cor responding1 parts in each lig-ure.
Referring" to the drawings l is the backplate having1 the flange 2 extending alongone side thereof, and the tonuue portion formed therefrom, and leaving; the side strips 4f.
5 is a flange formed along' the edge of the tongue 3, and corresponding` with the flan-ge 2.
6 are orifices through the flange 2.
7 is a ridge formed of the flange 2 by depressing` the same toward the back of the binder, the edge of said ridge being` set in from the edge of the flange 2 by approximately the thickness of the metal used.
l0 are filing posts projecting upwardly7 from the flange 5 opposite the orifices 6 of' the flange E2.
lt must be understood that the back plate with the tongue and the flanges as herein described are all formed from the one sheet of metal, having sufficient spring' to normally take the position shown in Fin'. 3, that is, with the tongue inclined inwardly at Specification of Letters Patent.
Application filed October 10, 1912.

serial No. 724,913.
the upper end, and the flange thereof turned therewith to tilt the filing posts with the upper ends thereof clear of the flange 2, whereby papers after being suitably perforated may be readily .filed thereon.
To close the binder it is only necessary to press the tops of' the side strips 4l with the flange 2 inwardly until the depressed portion forming the ridge on the flange E2 passes over the tongue 3, and springs downwardly with the edge thereof outside the ridge resting evenly on the top of the tongue 2, the said ridge meetingthe inner sideof the tongue 3, thus securely locking,` the binder. ils the ridge 7 passes over the tongue J3 the flange .2 springs upwardly, clearing' the tops of the posts l0, and when the flange springs downwardly into position upon the top of the tongue 3, the tiling posts lO enter the orifices 6, wherein they are firmly held.
'llo open the binder for the purpose of removing' sheets therefrom7 or filing' additional sheets thereon, it is only necessary to bear upwardly on the center of the flange Q, until the ridge 7 clears the top of the tonnuc rlllie saine action also diseng'apjes the liling posts l0 from the orifices 6, and the flange 2 is carried outwardly over the top of the tongue 3 bv the spring' of the metal in the side strips 4l, leaving` the filings' posts l() freely accessible. llt is not possible to open the binder except by this positive upward pressure on the center of the flange ik and as such a pressure could not be applied by any accidental means, there is no danger of the binder being opened by a fall or other accident.
rlhe binder as shown and described is of the simplest possible construction, and is readily formed from the one piece of sheet metal at a minimum cost, and when coinpleted is most attractive in appearance, and if desired may be covered on the outer surface with material such as cloth` leather or paper as customary with boolebaclc bindings. llt will be observed that, while the binder opens freely and locks securely, no rivets, hinges, springs or catches are used in its construction. llt is of' uniform strength throughout, and the only friction occurs at the point 7, so that it is practically free from wear and indestructible.
l/Vhat l claim as my invention is;
l. A loose leaf binder comprising a back plate formed of an integral piece of sheet metal having a flanged tiltable tongue portion and a filing post secured to said tongue and tiltable therewith.
2. A loose leaf binder comprising a back plate having side flanges and a' tongue formed therefrom and arranged to spring with one of said anges to a tilted position, binding posts secured to said tiltable flange and means for retaining said tiltable tongue and binding posts in lsquared posit-ion in said back plate.
3. A loose leaf binder comprising a back plate having flanges formed along the sides thereof and a tongue extending laterally across the bac-k from one of said flanges and leaving lateral end strips adapted to spring said tongue and the flange therewith to a tilted position, binding posts secured at one end thereof to said tiltable flange, orifices arranged in the other of said lianges, and adapted to receive the tiltable ends of said binding posts and a depression formed from one of said flanges and interlocking with the tiltalole end of said tongue.
Signed at Ottawa this sixth day of September, 1912.
