IMPROVEMENT IN RENiOVABLE BOOK-COVERS.

Specification forming part of Letters Patent No. 213,401., dated March 18, 1879; application tiled October 25, 1878.

To all whom it may concern:

Be it known that we, WILLIAM H. DoUTv and CHARLES H. DRAKE, of Shamolin, in the county of Northumberland and State of Pennsylvania., have invented a new and Improved Removable Book-Cover, of which the following is a specification:

Our invention relates to certain improvements in removable book-covers ot.' the class in which the back and sides may be together disconnected from the filling or contents, so that the contents may be removed and iiled away and a new set of pages or contents sup plied to the old cover.

The invention consists in providing thc stift' leaves of the cover with inwardly-projecting staples or studs, and the sides of the removable contents with slotted and tongued lockingstrips, of metal, adapted to receive and hold the staples or studs of the covers, so as to hold the contents and cover together. The parts are locked securely by a screw, as hereinafter described.

In the accompanying drawings, Figure lrepresents a portion of the contents of a book, with the slotted locking-plate connected therewith. Fig. 2 shows aportion ot' the cover havingthe staples connected to it, and Fig. 3 is a section showing the two parts connected together.

Similar letters of reference indicate corresponding parts.

A represents the outer cover, in the stiff sides of which is incorporated or riveted a plate, a, that has projecting from it staples b on theinner side. B represents the lilling of pages or contents of the book, which is provided with stift sides, on one side ot' which is riveted a metal strip, c. This strip c is formed with slots d, corresponding in position to the staples b of the cover when the parts are together, which slots are cut in a shape to form a tongue, e.

In applying the cover A to the contents B, the staples b will pass through slots d of strip c, and a slight endwise movement of the two parts in opposite directions will cause the tongues cto enter staples b, and the book and cover will be connected.

Instead of staples b, slots d, and tongues c, We sometimes provide the plate a. with L- shaped studsf, and the plate c with longitudinal slots g, which act in asimilar manner and upon the same principle of a tongue and eye for holding the said plates together.

To retain the book-cover and contents together and prevent their accidental separation, small screws z' are inserted through holes k in strip c, and enter screw-threaded holes in the projection l on the strip a.

Instead of the screws, a at spring, h, can be attached to the strip cin such position that its free end will spring down behind the staple b or stud f when the parts are in place; but we do not claim such means of fastening-to wit, the spring.

It is to be understood that the relative position of the tongues and eyes may be reversed, it' desired, the eyes being upon the filling and the locking-strip on the cover.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. 'Ihe combination of the plate a, att-ached to cover A and provided with staples b, and the plate c, attached to filling B, and pro. vided with the slots d and tongues c, substanA tially as and for the purpose described.

2. The combination of plate c, provided with the holes k, and the plate a, having the screwthreaded projections land the screws t', for preventing the accidental separation of the said plates, substantially as described.
