MOVABLE INDEX FOR LETTER-COPY BOOKS.

SPECIFICATION forming part of Letters Patent No.4*76,708, dated June 7, 1892.

Application filed March l0, 1892. Serial No. 424,437. (No model.)

To all 'LU/"1,0m it may concern:

Be it known that I, MILES VERNON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,have invented new and useful Improvements in Movable Indexes for Letter-Copy Books, of which the following is a specification.

This invention relates to a movable index for letter-copy books, and by means of this invention the index can be consulted separately from the book or conjointly therewith, as desired, without its being necessary to turn back and Vforth toward and from the index, as fully set forth in the following specification and claims, and illustrated in the accompanying drawings, in which Figure l shows aplan view of thebook open and of the index. Fig. 2 shows the index moved out of the book. Fig. Eis atransverse section of the book.

In the drawings the leiter A indicates the back of the book, having covers B and leaves C of the usual construction.

The index D is constructed, as usual, with the well-known marginal lettering or alphabet. The index D is secured at one corner by a pivot or joint E to theinner side of one corner of a cover B, preferably the rea-r cover, so that the index can be swungin a plane parallel with the cover into the book, as in Fig. l, or out of the book, as in Fig. 2.

To prevent the index from swinging too easily on the pivot E, a pad or spring F may be interposed between the index D and cover B, Fig. 3, so as to exert friction.

By swinging or moving the index to the position shown in Fig. 2 the book can be closed and the index will still be left exposed to examination as a practically independent book or pamphlet without disturbing the main book, or, if desired, the index when resting alongside the book, as in Fig. 2, can be consulted, and as the desired entries in the index are found the corresponding pages of the leaves C can be turned to without its being necessary to continually turn toV the back of the book to reach the index and then forward again to reach the desired page.

By this invention not only time is saved and annoyance avoided, but by doing away with the continual turning back to reach the index I avoid the niussing and crninpling of the leaves C, which is especially apt to occur Ain the case of thin tissue-leaves, such as generally employed in letter-press copying-books.

W'hat I claim as new, and desire to secure by Letters Patent, is-

l. A letter-press copy-book consisting of the covers B, the leaves (l, and the index D, pivoted at one corner to the inner side of one of the book-covers to swing in a plane parallel with the cover into and out of the book, substantially as described.

2. A letter-press copy-book consisting of the covers B, the leaves C, the index D, and the pivot E, engaged with a corner of one of the book-covers and pivotally connecting one corner of the index therewith, so that the index can swing in a plane parallel with the cover into and out ot the book, substantially as de' scribed.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
