BINDER.

Application filed October 12,1925. Serial No. 61,976. r

is used.

The usual method of locking the hingedly mounted binder top to the several posts eonsists of aligning each of the posts so that the respective post engaging pin may enter a transverse hole formed in each. The faults and short comings of the binder now in use need not further be mentioned.

It is an object of this invention to provide novel post engaging means which includes means for retaining each of the posts in the proper lock member engaging position.

' A still further object of this invention is the provision of a post engaging means which is hingedly carried by a support plate attached to the binder cover and which carries the post locking member.

An even further object of this invention is the provision of a binder post having oppositely disposed notches in each of its ends whereby the locking member may engage the same after, all the posts have been engaged by a guide member which supports the post locking means. Other objects pertaining to the compactness of structure, neatness and simplicity of design and the lack of a large number of complicated parts, will be set forth in thefollowing specification referring to the accompanying drawings. in which;

Figure 1 is a perspective view of a loose leaf binder constructed in accordance with the present invention.

Fig. 2 is an enlarged vertical section of the binder taken on line IIII of Fig. 1.

Fig. 3 is an enlarged fragmentary detailed cross section of the binder taken on line IIIIII of Fig. 2 and showing the same with the top or one of the covers thrown back to the open position.

Fig. 4 is a view similar to Fig. 3 with the book in the closed position.

Fig. 5 is a perspective view of the post engaging member showing the slidably;

' means showing one method of permanently locking the post locking means in the closed position.

Fig. 7 is a plan view of the open binder showing another way of hingedly mounting tllie post engaging member to the support p ate.

Fig. 8 is an end view of the binder shown in,Fig. 7, andv Fig. 9 is an enlarged perspective View of one of the binder posts entirely removed from the remaining structure.

Like reference characters refer to similar parts throughout the several views, and the number 10 designates the covers of a loose leaf binder which maybe bound together by a back 12 and which contains the ordinary loose leaf sheet 13.

In describing the post engaging member and locking means, together with the several minor parts,- it should be borne in mind that there is a similar structure supported or carried at the top and-bottom ofthe sheets 13 by each of covers 10. A support plate 14' is rigidly attached to each cover 10 by rivets or analogous means 15 with a portion thereof extended beyond the hinged edge of cover 10 to form a hinge eye 16 at each of its ends. A hinge pin 17 is carried by each hinge eye 16 and, in the instance shown rigidly engages a post engaging member 18 whereby the same is hingedly supported-to support. plate 14 and thence to cover 10. For the purpose of illustration, three sheet carrying posts 19 have been shown, but it is understood that the invention maybe used in connection with any number of posts which may be required to effectively hold sheets 13 in place. As is shown in Fig. 9 each of posts 19 is provided with a notch 20 adjacent each end thereof, said notehes faeing or opening out on opposite sides or edges of the post. Each post engaging member 18 has an opening 21 adapted to register with ing 21 of post engaging member18, a guide 7 means in the form of a. wall 22 may be formed integrally with member 18. This wall 22 engages the bound "edges of the sheets 13 and tends'to prevent their curling or rutfling in the binder, and when wall 22 has engaged the edges of sheets 13, it will be seen thatopening 21 will be in a position to allow the passage of posts 19 there-through. This wall 22 may be of any width up to and including half the distance between the stack of sheets 13, but it is preferred to construct it substantially as shown in the drawing.

After post 19 has been engaged by post engaging member 18 by passing through openings 21, the locking mechanism is brought into play to rigidly hold the posts and all the related binder parts in the bound position. Each" end of post 19 has passed far enough through post engaging member 18 to allow the notch 20 to be entered'by a locking bar 23 slidably mounted through the meansof a well known slot and pin construction 2st to the sheet engaging member 18. This locking bar 23 is also provided with openings 25 which register with openings 21 withthe post engaging member 18 when the bar is in the unlocked position.

This permits the passageof post 19 there through, yet allows "bar 23" to be moved so that a portion thereof adjacent each opening 25 will enter notch 20 to grip the post and keep the same from being moved in any direction. The notches 20 of each post 19 are provided with inclineswhich continue from the sides nearest the end of the post as shown in Fig. 9, and which. act as guides or guide faces for bar 23. This facilitates the entry of bar 23 and does not require that the bar and notches be in close alinement before the locking movement is imparted.

A finger engaging member 26 may be proJ vided on member 23, and a transverse crimp 27 formed in )ost en a ing member 18to' act as a positive positioner and to more or less retain member 23 in the post locking position. I f

It will be seen that through the use of the post engaging member 18 and the openings 21 formed therein,that no time islost in positioning all of theposts of the binder in place-to immediatelyreceive the locking bar 23. It is preferred to have the upper and lower locking bar of each binder move in opposite directions to engage the oppositely facing notches20 of post 19 as shown in Fi.gs.'2 and 9; Support plate'l t should also benotched to avoid striking the tops of posts. 19 and to permit the. binder to be closed to take up the least amount of room as shown in Fig. 4. Itis 'not partioular at what point on postengaging mem ber 18 the hinge pin17 is attached? It may,

if desired, be attached to ,wall 22 of this member, or ifdeslred the well knownpiano hinge construction "may be used between post engaging member 18 and support plate 14-.

to'a support plate. 1

binder comprising a pair ne6as74 binder after the desired entries have been.

made on all the sheets contained therein, any well known means may be used to prevent the further manipulation of loekingbaif 23, but it is preferred to use a depressible lug and notch construction as shown in 6. The lug 29 which is formed between two slits cut in the head of the pin of the slot and pin construction 2 1 is punched down into notch 30 formed in the slotthrough the use of some sharp instrument. Fig. 6 shows the locking bar 23in the open or unlocked position with the notch 30 clearly shown. hen thebar is in the lockedor closed position, notch 30 falls-directly beneath the cut out lug 29 and will easily and effectively receive the same whenever'it is desired to permanently lock the binder in such a way that the removal ,ofsheetswithout mutilat ing the same is prevented;

a sheet.
