IMPROVEMENT IN DETACHABLE BOOK-COVERS.

Specifioniion forming part of Letters Patent No. 208,689, dated October E, 1879; application 1i1ed March 15, 1878.

T0 all whom zt may concem:

Be it known that I, EDWARD F. NEWKIRK, of Newark, in the county of Licking and State of Ohio, have invented a new and useful Improvement in Detachable Oovers for Memo randum-Books, of which the following is a full, clear, and exact description.

This invention relates to detachable covers for memorandum-books, writing-tablets, and the like, the leaves of which are at one end or side permanently connected together by a reg nlar backing.

My invention consists in providing one of the flaps of the cover With two sockets on opposite edges, for the reception and retention of the bound back of the memorandnm-book or tablet, each of the sockets being constructed with a fixed in wardly-proj ectin g need le-pointed pin to enter between the bonnd leaves, and one of them being pivoted or made laterally adinstable, so that it can be swnng out of the way when it becomes necessary to insert or remove a tablet or book.

Tire swinging or adj ustable socket is constructed to catch or look onto a detent when in position around the corner of the book.

In the accompanying drawings, Figure 1 is a perspective view of my improved detachable cover, with the front flap thereof thrown up to show the tablet contained therein. Fig. 2 is a similar perspective view of the cover, but withont the tablet, and showing the adjustable soeket swung outwardly to admit of the insertion of a tablet or book. Fig. 3 illustrates the holding-sockets in perspective.

The same letters of reference indicate like parts in all the figures.

The flaps A of the cover may be made of any suit-able material and connected together by a flexible back, B, in the usual manner.

C and D refer to the respective sockets for secnring the book or tablet to the cover. These sockets are preferably made of sheet metal, in the form best shown in Fig. 3, the base-plate being elongated to afford a long bearing for firmly securing them to one of the flaps of the cover. In the exampIe shown they are located near the flexible back B and at opposite edges of the back flap of the cover.

Each socket has a needle-pointed inwardly and laterafly-projecting fixed pin a, adapted to enter between the bound leaves of the 10001: or tablet.

Socket 0 is permanently and rigidly secnred, but socket D is so connected to the flap that it may be moved to one side in an outward direction, at least so far as to permit of the latera1 insertion of the book or tablet in socket 0. To this end it is here shown as pivoter], at d. near the extreme end of its eiongated baseplate D, and as provided With a hole, d, therein, adapted to engage a stud, (1*, on the flap of the cover when it is swnng around to clasp the corner of the book or tablet after the lateral insertion of the saine in socket 0.

The stnd 61 projects only slightly from the flap, and the base-plate D of socket D is made somewhat elastio, so that it can be bent up slightly t0 spring it over the said stud, or to disengage it therefrom, as the case may be.

It Will be observed that the sockets surronnd the corners of the baek of the book or tablet, and that the needle-pointed pins will prevent the endwise withdrawal thereof.

Te hold tablets from Which the leaves are successively torn, the tablets must be perforated near the back, so that stubs Will romain With the backing, by which the tablet may be retained until all its leaves have been usedup.

It is clear that the adjustable socket can be mounted in quite a different manner from that I have shown and described without departing from the principle of my invention.

VVhat I daim as my invention, and desire to secure by Letters Patent, is-

1. A detachable cover for memorandnm books, writing-tablets, and the like, o'ne flap of which is provided with a pair of sockets, having inwardly projecting needle pointed pins, one of the sockets being laterally shiftable, substantially as and for the pnrpose specified.

2. The combination, snbstantiafly as specified, With one of the flaps of a detachable cover for memorandum-books, writing-tablets, and the like, of a fixed socket having an inwardlyprojecting needle-pointed pin, a similarly-constrncted pivoted socket, and a stud for locking said pivoted socket.

In testimony whereof I have signed myname to the foregoing specification in the presence of two subscribing witnesses.

EDVVARD F. NEWKIRK.
