DEVICE FOR SUSPENDING AND SECURLNG TELEPHONE-DIRECTORIES.

Specification of Letters latent.

Patented Apr. 8, 1919.

Application filed July 20,1917. Serial No. 181,921.

To all whom it may concern:

Be it known that I, WILLIAM E. LUDLoW, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of ()hio, have invented a certain new and useful Improvement in Devices for Suspending and Securing Telephone-Directories, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

Telephone companies have experienced a serious. loss in the number of telephone directories which are carried away from public booths. The object of the present invention is to provide a device for conveniently supporting the telephone directory, and at the same t1me so securing it that it will be difficult enough for removal so that the directory will not ordinarily be purloined. At the same time my device is readily removable from the directory by usual tools, en-' abling the substitution of a new book.

My supporting and securing device is clearly illustrated in the drawings hereof and is hereinafter more fully described, and its essential characteristics are summarized in the claims.

Figure 1 is a perspective view of my suspending and securing device attached at its upper end and secured at its lower end -to a telephone directory; Fig. 2 is an enlarged elevation of the device adjacent to the securing end; Fig. 3 is an edge view of the parts shown-in Fig. 2; Fig. 4 is an enlarged vertical section through the part of the device which engages the telephone directory; Fig. 5 is a detail in cross-section on the line 5 on Fig. 4.

In the drawings, A indicates a telephonedirectory and at the same time allows the desired freedom of movement of it in use.

The strap 4 is asheet metal member bent into a U-shape, and if desired may be made of spring material. :The eye 3 has a shank 7 extending through the crown of the U and provided with an upset head 8 on the inner side of the U. By this means the eye is permanently secured to the U and at the same time swiveled to it. r

The U-strap is ofsuch size as to readily but freely embrace the two sides of the telephone directory A. This strap is provided with two holes opposite each other through which the bolt 5 extends. This bolt is of such size that it may readily ass through a hole a formed through the te ephone directory adjacent to the corner. The bolt is provided atone end with screw threads 10 and has on the other end a suitable head 11, which is preferably rounded, as shown. The bolt 5 may be of the carriage bolt type, as shown, having a square portion 12 on its shank occupylng a square 11016111 the strap whereby it is prevented from turning.

The nut 6 is shown as an lar and adapted to be turned by a wrenc On the inner face of this nut is a radial notch 13 which is adapted to coact with lug 15 ofl'set outwardly from that side of the strap 4:. Fhis lug is abrupt on the side engaged by. the wall of the notch when the nut unscrews, but is gradual on the side engaged when the nut is screwing on, as clearly shown in Fig. 5. The result isthat the nut may be screwed on much more readily than it ma be screwed 01f. The body of the embrace book limits the inward movement of the arms of the U- shaped' strap, though the paper will, of course, stand some compression. Accordingly, by means of a wrench, the nut may be turned on over the ratchet detent described tightly enough so that it is impossible to remove it with ones fingers. It may, however, be removed by a suitable tool.

It is notthe intention to supply a burglarproof device, but to supply a holder which makes it so inconvenient to remove the book that it will not ordinarily be done. Experience has demonstrated that the removal of the books comes from actual users of the booth, who incidentally remove the book, rather than from persons entering the booth with a special intention of removing the book. Accordingly, while such ordinary tools as a suitable wrench or a pair of pincers are sufficient to effect the removal, the fact that they are required is effective in preventing a very large per cent. of the removals. At the same time it is a very simple matter for the em loyees of the telephone company, who supp ies new books, to remove the former issues.

Having thus described my invention, what I claim is:

1. The combination, with a book, of a U- shaped strap of yielding metal having parallel legs embracin the book, there being alined holes through the book and the two legs of the U, a bolt passing through said I holes and provided with a nut, a ratchet detent connection between the nut and strap enabling the elasticity of the book to keep this connection in engagement, an eye swivwith a U-shaped strap,

passing through two legs eled to the crown of the strip, and a flexible supporting member secured to the eye.

2. In a device for supporting and securing telephone directories, the combination of an eye swiveled to the eye, a bolt 'of the strap and and threaded at thereto, a chain secured having a head on one end the other, and a nut screwing onto the thread and having a notch in its inner face and an outward projection on the strap adapted to occu such-notch.

In testimony w ereof, I hereunto afiix my signature.

WILLIAM E. LUDLOW.
