OORPURATIGN GF NEW YORK Loosen-Tsar BINDER Application filed September 29, 1927. v Serial No. 222,682. I

The present invention relates to loose leaf binders and more particularly to the type in which the binder comprises two binding members, one of which has impaiing projections thereon and the other of which has locls the purpose of repair or the substitution of others. Another object of the invention is to provide a leaf-retaining bar which may cooperate with a transfer member having inipaling projections and associated with a loose leaf binder so that the transfer member may be used as a temporary binder as well as for transferring leaves in the binder.

To these and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described: the novel features being pointed out in the appended claim.

In the drawings Fig. 1 is a perspective view of the loose leaf binder showing the binder members separated;

Fig. 8 is'a plan view of the retai and V Fig. 9 is a fra mentary side view with the parts in section showing the transfer memher with the retaining bar arranged thereon.

In the illustrated embodiment of this invention 1 indicates the back piece, 2 the cover leaves and 8 supporting bars for the binding members, the supporting bars being hinged at l to the hack piece 1 and hinged at 5 to the cover members 2.

Prior to this invention, it has been customary, in this ty lie of binder, to mount the bars of the binding members in the positions occupied by the supporting bars 3. The result is that when the binder becomes broken, in

either of its binding members, the binder must be thrown away or an expensive repair bill is involved. According to this invention the binding members may be readily repaired or replaced by others, due to the fact that the binding members are detachably arranged on the inner faces of the supporting bars 8. To this end, the binding membe 6 which is in the form of a bar or strip with spaced impaling projections 7 extending laterally from one side thereof is, by screws 8 passed through the bar 6, anchored to a supporting bar 8 and held to'such supporting bar. The other binding member or bar 9 is in the form of a chan nel member, the open s1de of which lies on "the inner side of the bar 3 and is held thereto by screws 10. This binding member 8 has the lockingmeans arranged therein in the form of a usual sliding locking bar 11 having a fin er niece atone end through which it 1s t) I V I o k: A 0

moved in one d1 ection against the action of a helical spring 12 also contained within the binding member 9. This locking bar has shoulders thereon as usual for engagement with shoulders 13. formed on some of the imhousing 9 to be engaged by the locking bar 11.

lVith this arrangement either or both of the binding members may be readilyv disconnected from the supporting bars 3 for the purpose of repair or for replacement by others.

As it is customary in this type of binder, there may be employed a transfer member comprising, in this instance, a. bar 15 with ims paling posts or projections 16 extending therefrom, these impaling posts being adapted to pass into any one of the openings 17 in the leaves 18 between the openings through which the impaling projections 7 pass. This transfer member also has projecting from the opposite side of the bar short posts 19 with shoulders 20 thereon. These short posts are adapted to pass through the openings 21 in the housing 9 to be engaged by locking shoulders on the locking bar 11, as is well-known in this art. Openings 1% are provided in the transfer member 15 which aline with the openings let so that the shouldered posts 7 may pass through to engage t 1e clutching means.

Another feature of this invention is to associate with the transfer member of a binder of this type, means for retaining the leaves on the transfer member so that the transfe member may act as a temporary binder. This means, in this instance, consists of a retaining bar 22 having openings 23 through which the posts 16 of the transier Adjacent the ends of the retaining bar are spring clutches 2% each in the form of a leaf spring riveted at one end at 25 to the retaining bar 22 and having its free end 26 extending slightly over one of the openings 23 so that when post 16 is passed through the opening, the spring clutch will be displaced and will enter into clutching engagement with a portion of the post projecting Ul rough the opening. A lip 27 projects from one side of the clutch beyond a side of the retaining bar and may be manipulated to break the engagement between the clutch and the post in order to permit the withdrawal of the retaining bar from the transfer member. l Jith this arrangement the transfer member with the retaining bar may be used as a temporary binding means for those leaves which have been removed from the binding projections Y. l he retaining member 22 may be arranged in apocket 28 formed on the inner face of one of the covers 2.

From the foregoing it will be seen that there has beenprovided, in a loose leaf binder of the type having the binding member provided with impaling projections and the binding member having locking means for interlocking with impaling projections on the first-mentioned member, means for securing the binding members to the cover so that the members may be readily removed or re placed by others. There has also been provided in connection with a transfer member in binder of the class described, a retaining iner ber may pass.

the impaling projections on the first-named binding member, and a transfer member hav- WILLIAM F. W ARNER, J R.
