Application September 21, 1934, Serial No. 744,882 In Canada November 9, 1933 9 Claims.

This invention relates particularly to binders adapted for use with books such as telephone directories which are provided with thin flexible covers, and our object is to provide a cover which the book, which is neat in appearance, which will not mar furniture with which it may contact, and which may be locked to prevent unauthorized removal of the book from the cover when the cover is chained in place.

We attain our object by means of the constructions which may be briefly described as follows: A

back is provided of channel form, preferably made of vulcanized fiber or other non-metallic sub,- stance which will withstand hard usage and yet will not mar table or other surfaces. Within this channel is secured a. metal back plate carrying at one end a fulcrum member for a hinged retaining bar and at the other end a lock for the free end of the holder bar. A case is provided comprising stiff covers connected with a stiff back by means of flexible hinge members. This case is fitted into the channel back and the hinge members are so proportioned that the covers hinge at the edges of the channel back. Within the case the back of the directory is fitted.

The retaining bar is of thin metal so as to take up as little space as possible in the book between the leaves of which it is inserted, and is pushed down to a position in which its end will be secured by the lock.

The fulcrum member is also furnished with an eye for the attachment of a chain or for direct engagement with a hook.

The invention is hereinafter more specifically described and is illustrated in the accompanying drawing in which Fig. 1 is a plan view of the holder without the covers;

Fig. 2 a cross section of the holder with the covers in place;

Fig. 3 a face view of the fulcrum member with the front removed;

Fig. 4 a face view of front removed;

Fig. 5 a longitudinal section; and

Fig. 6 is a front elevation of the lock casing.

In the drawing like numerals of reference. indicate corresponding parts in the different figures.

I is a channel-shaped member, preferably made of vulcanized fibre or similar tough, strong material not likely to scratch surfaces with which it may come into contact. 2 is a metal back plate, which, at each end, is formed with inverted U- shaped bends 3 and .4 respectively. 5 is an unthe lock member with the derlying metal plate, which is welded at each end to a part of the adjacent U-bend. At the left hand side in the drawing this underlying metal plate is shown as formed with the pair of hinge knuckles 6 which terminate in the lugs I 5 which are welded to the outer side of the adjacent U-bend. The metal plate thus closes the underside of the lJ-bend. Similarly the plate 5 closes the underside of the U-bend 4 at the other end of the device. Preferably the outer side of the U-bend is formed with the lug or flange 21 which is welded to the metal plate 5.

In the hinge knuckles 6 are journalled the arms 8 of the hanger member 8, which forms a loop by means of which the-device may be hung from a n l r h The U-bend 3 forms a fulcrum for the retaining bar H, which is preferably formed of thin steel so as not to take up too much room in the book with which the binder is used. Fitted in the 20 U -bend 3 is a filler piece 9, which is provided with a lateral projecting pivot l0 and is cut away for the passage of the end of the retainer bar which is formed with a hole through which the pivot passes. I 25 The U-bend 4 forms a lock casing in which slides the latch membfil 13, Which is provided with the bevelled nose Hi. This latch member is slidably mounted between the top and bottom of the lock casing. At one side thereof there is positioned between the walls of the lock casing the spacer member 16, which preferably extends from top to bottom of the cavity. At the other side of the lock casing is positioned the spacer member I! which preferably does not extend 35 down to the bottom of the cavity leaving room for the tail 18 of the latch member I3 to pass thereunder. The latch member is also provided with the shoulder l9 which is adapted to engage the inner side of the spacer member H to limit 40 the movement of the latch member l3 to the left. The latch member is normally moved to the left as shown in the drawing by means of the coil spring 28 which is positioned in the slot l5 in the latch member and engages the spacer member l6. .5 In the lock casing is formed a key hole 22 and on the latch member is formed a shoulder 23 engageable by a key inserted through the key hole to press the latch member back to release the retaining bar. The retaining bar is adapted to pass into the slot 20 formed in the lock casing 4 and has a hole 21 formed therein. When the retaining bar is pressed down it engages the bevelled nose l4 and presses back the latch member until the nose can engage in the hole 2| formed in the 55.

retaining bar. Of course, other means than a key might be provided to release the latch member H3.

The end of the retaining bar is preferably twisted to the horizontal position shown at 29 in the drawing to form a finger grip, by means of which it may be readily manipulated.

The

metal back plates

2 and 5 are secured to the channel member I by means of the rivets 30 and holes 3! are preferably formed in the metal plates through which screws may be passed to secure the device to a stationary support. In this case, of course, the vulcanite fibre back requires to be bored through in alinement with the holes 3|.

With the device is preferably used a case comprising the covers 24 connected to a back 32 by flexible hinge members 33, which hinge members are so proportioned that the covers hinge at the upper edges of the channel member.

When the device is to be used the latch member is released by means of a key and the retaining bar thrown back. The book to be held in the device is then placed in position with its back within the channel member i and is opened substantially midway between the back and front. The retaining bar is then brought down between the leaves of the book and is pressed down through the slot Zil and is automatically locked by the sliding latch l3. The temporarily bound book is then ready for use in any manner desired. While the book may have its back directly inserted in the channel member I the case comprising the covers, back and hinge members will usually be first inserted. (See Fig. 2).

From the above description it will be seen that we have devised a construction which will satisfactorily attain the object of our invention as set forth in the first part of this specification.
