MABERRY L. DAVIDSON, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO WILKINS BROS, OF MILFORD, NEW HAMPSHIRE, A FIRM.

BOOK.

Specification of Letters Patent.

Patented Dec. 12, 1905.

To aZZ whom it may concern:

Be it known that I, MABERRY L. DAVIDSON, a subject of the King of Great Britain, and a resident of Boston, in the county of Suifolk and State of Massachusetts, have invented new and useful Improvements in Books, of which the following is a specification.

My invention relates to books, and particularly to that class of books comprising a cover or holder and a separable or removable pad or body of leaves, such as are used for manifolding sales-books, blank notes, or similar purposes, in which the covers may be used again and again and the pads or the like renewed when the leaves have been used up.

More specifically, my invention relates to books of this character in which the cover is provided with a holding device for a hook or tongue upon the removable pad or body of leaves. An example of a book of this sort is to be found in- United States Patent No. 647,933 for a manifolding sales-book and holder, in which a pivoted bail upon the cover cooperates with a tongue or corresponding bail upon the pad to hold the parts together.

The object of my invention is to provide a device which will admit of assembling or detaching the parts more easily and expeditiously than has heretofore been possible and in which the pad or body of leaves, when the parts are assembled, will be more securely held against the possibility of accidental dislodgment than the devices heretofore produced. To this end I provide upon the cover of the book a hook-engaging member or pocket and upon the removable pad or body of leaves a hook or tongue adapted to slip into the hook-engaging member or pocket, and so hold the pad or the like to the cover. To prevent the dislodgment of the 4 hook and the hook-engaging member, I prothe book being open and the parts assembled. Fig. 2 is a section through the line 2 2 of Fig. 1. Fig. 3 is a side view of the book, showing the method of assembling the parts.

Referring to the drawings, 1 represents the holder or cover of the book, which may, as usual, be made of any suitable material, such as cardboard, leather, or cloth. The holder or cover may be singlethat is, it may be provided only upon one side of the bookor it may be doublethat is, it may embrace both sides-in which case the covers 1 and 2 are connected by some suitable flexible material, as shown at 3.

4: represents a pad or body of leaves bound together at the edge in any suitable manner, as by means of a binding-strip of cardboard or the like fastened over the edges of the leaves, as shown at 5. Upon the back of the pad 4: a hook or tongue 6 is provided, extending substantially parallel with the body of the leaves. This hook or tongue may be of any suitable material and may be attached to the pad in any convenient way. An admirable form of construction is that shown in the drawings, in which the binding-strip 5 is extended beyond the threads or wires 7, which bind the strip 5 and the leaves of the pad together, so as to form the tongue 6, which lies along the under side of the pad. To cooperate with the hook or tongue 6, I provide upon the cover a hook-engaging member or pocket 8. The movable stop to prevent the disengagement of the tongue and the engaging member is preferably in the form of a'plate 9, pivoted to the cover at 10 and yieldingly held in a vertical position with reference to the cover by coil spring'll. When in its normal and operative position, plate 9 engages the edge of the pad, as shown in Fig. 2, and prevents the tongue 6 from slipping out of pocket 8. When a pad is to be removed or inserted, plate 9 is swung down substantially into the plane of the cover, as shown in Fig. 3, out of the path of the edge of the pad. The hook or tongue may then be readily slipped into or out of hook-engaging member or pocket and the parts assembled or separated. Plate 9 is then released and the spring llat once restores it to its normal position.

It will be clear that no particular form of stop or connection between the stop and the cover is necessary, the only condition necessary to be observed being that the stop shall [with said pocket; and a stop pivoted upon be adapted normally to prevent such movement of the pad as to cause the hook to slide in or out of the hook-engaging member and shall be movable to admit of such manipulation of the pad. Neither is any specific form of hook or hook-engaging member required.

What I claim is- 1. A book comprising a cover; a movable pad or body of leaves; a hook upon one of these parts; a hook-engaging member upon the other, cooperating with the hook; a stop pivoted to the cover and adapted, when in its vertical position with reference to the cover, to engage the edge of the pad or body of leaves and prevent the disengagement of the hook and the hook-engaging member, and a spring for holding the stop in a vertical position while in use.

2. A book comprisinga cover provided with a hook-engaging member, a movable pad or body of leaves provided with a hook cooperating with the hook-engaging member, a stop pivoted to the cover and adapted, when in its vertical position with reference to the cover,

to engage the edge of the pad or body of leaves and prevent the disengagement of the hook and the hook-engaging member, and a spring for holding the stop in a vertical position while in use.

3. A book, comprising a cover provided with a hook-engaging member; a removable pad or body of leaves provided with a hook cooperating with the hook-engaging member; a stop pivoted to the cover and adapted when in its vertical position with reference to the cover to engage the edge ofthe pad or body of leaves and prevent the disengagement of the hook and the hook-holder; and a spring normally urging the stop toward such vertical position.

4:. A book, comprising a cover provided with a pocket; a removable pad or body of leaves provided with a tongue cooperating the cover near the mouthof the pocket normally adapted to prevent the disengagement of the tongue and pocket and capable of movement to admit of such disengagement.

5. A book, comprising a cover provided with a pocket; a removable pad or body of leaves provided with a tongue cooperating with said pocket; and a movable stop upon the cover near the mouth of the pocket yieldingly held in position to prevent the disengagement of the tongue and pocket.

6. A book, comprising a cover provided with a pocket; a removable pad or body of leaves provided with a tongue cooperating with the pocket; and a stop pivoted to the covernear the mouth of the pocket, yieldingly held in a vertical position with reference to the cover, and normally adapted to engage the edge of the pad or body of leaves and retain the tongue in engagement with the pocket.

7. A book, comprising a cover provided with a pocket; a removable pad or body of leaves provided with a tongue cooperating with the pocket; a plate pivoted to the cover near and across the mouth of the pocket, adapted to be swung substantially into the plane of the cover or into a position perpendicular to the cover; and a spring normally urging the plate into such perpendicular position.

8. In a book of the character described, a hook-engaging member adapted to receive a hook upon a pad or the like; that pad, provided with a hook; and a springactuated movable stop normally adapted to engage one side of the pad to prevent the disengagement of such hook and the hook-engaging member and movable against resistance of the spring to admit of the insertion of such hook into, or the removal of such hook from, the hookengaging member.

9. In a book-cover of the character described, a pocket adapted to receive a tongue upon a pad or the like, and a plate pivoted to the cover near and across the mouth of the pocket yieldingly held in a position substantially perpendicular to the cover and in the path of the edge of such pad when its tongue is in the pocket, and movable out of the path of the pad to admit of the insertion of such tongue into or the removal of such tongue from, the pocket.
